But what if we had many more? Or what if the AIs we built effectively had many more? What kinds of things might then become possible? At 100 billion neurons, we know, for example, that compositional language of the kind we humans use is possible. At the 100 million or so neurons of a cat, it doesn’t seem to be. But what would become possible with 100 trillion neurons? And is it even something we could imagine understanding? </p>\n<p>My purpose here is to start exploring such questions, informed by what we’ve seen in recent years in neural nets and LLMs, as well as by what we now know about the <a href=\"https://writings.stephenwolfram.com/category/computational-science/\">fundamental nature of computation</a>, and about neuroscience and the operation of actual brains (like the one that’s writing this, imaged here): </p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2025/05/sw05202025catscimg1.png' alt='What If We Had Bigger Brains?

Imagining Minds beyond Ours' width='611' height='244'><span id=\"more-68380\"></span></p>\n<p>One suggestive point is that as artificial neural nets have gotten bigger, they seem to have successively passed a sequence of thresholds in capability:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/05/sw05202025catsbimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/05/sw05202025catsbimg1.png' alt='' title='' width='423' height='144'> </div>\n</p></div>\n<p>So what’s next? No doubt there’ll be things like humanoid robotic control that have close analogs in what we humans already do. But what if we go far beyond the ~10<sup>14</sup> connections that our human brains have? What qualitatively new kinds of capabilities might there then be? </p>\n<p>If this was about “computation in general” then there wouldn’t really be much to talk about. The <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> implies that beyond some low threshold computational systems can generically produce behavior that corresponds to computation that’s as sophisticated as it can ever be. And indeed that’s the kind of thing we see both in lots of abstract settings, and in the natural world. </p>\n<p>But the point here is that we’re not dealing with “computation in general”. We’re dealing with the kinds of computations that brains fundamentally do. And the essence of these seems to have to do with taking in large amounts of sensory data and then coming up with what amount to decisions about what to do next. </p>\n<p>It’s not obvious that there’d be any reasonable way to do this. The world at large is full of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>—where the only general way to work out what will happen in a system is just to run the underlying rules for that system step by step and see what comes out:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/05/sw05202025catsdimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/05/sw05202025catsdimg4.png' alt='' title='' width='531' height='201'> </div>\n</p></div>\n<p>And, yes, there are plenty of questions and issues for which there’s essentially no choice but to <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/#the-hard-limit-of-computational-irreducibility\">do this irreducible computation</a>—just as there are plenty of cases where <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">LLMs need</a> to <a href=\"https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/\">call on</a> our <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> computation system to get computations done. But brains, for the things most important to them, somehow seem to routinely manage to “jump ahead” without in effect simulating every detail. And what makes this possible is the fundamental fact that within any system that shows overall computational irreducibility there must inevitably be an infinite number of “pockets of computational reducibility”, in effect associated with “simplifying features” of the behavior of the system. </p>\n<p>It’s these “pockets of reducibility” that brains exploit to be able to successfully “navigate” the world for their purposes in spite of its “background” of computational irreducibility. And in these terms things like the progress of science (and technology) can basically be thought of as the identification of progressively more pockets of computational reducibility. And we can then imagine that the capabilities of bigger brains could revolve around being able to “hold in mind” more of these pockets of computational reducibility. </p>\n<p>We can think of brains as fundamentally serving to <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">“compress” the complexity of the world</a>, and extract from it just certain features—associated with pockets of reducibility—that we care about. And for us a key manifestation of this is the idea of concepts, and of language that uses them. At the level of raw sensory input we might see many detailed images of some category of thing—but language lets us describe them all just in terms of one particular symbolic concept (say “rock”).</p>\n<p>In a rough first approximation, we can imagine that there’s a direct correspondence between concepts and words in our language. And it’s then notable that human languages all tend to have perhaps 30,000 common words (or word-like constructs). So is that scale the result of the size of our brains? And could bigger brains perhaps deal with many more words, say millions or more? </p>\n<p>“What could all those words be about?” we might ask. After all, our everyday experience makes it seem like our current 30,000 words are quite sufficient to describe the world as it is. But in some sense this is circular: we’ve invented the words we have because they’re what we need to describe the aspects of the world we care about, and want to talk about. There will always be more features of, say, the natural world that we could talk about. It’s just that we haven’t chosen to engage with them. (For example, we could perfectly well invent words for all the detailed patterns of clouds in the sky, but those patterns are not something we currently feel the need to talk in detail about.)</p>\n<p>But given our current set of words or concepts, is there “closure” to it? Can we successfully operate in a “self-consistent slice of <a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/#the-notion-of-interconcept-space\">concept space</a>” or will we always find ourselves needing new concepts? We might think of <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/#generalized-economics-and-the-concept-of-progress\">new concepts as being associated with intellectual progress</a> that we choose to pursue or not. But insofar as the “operation of the world” is computationally irreducible it’s basically inevitable that we’ll eventually be confronted with things that cannot be described by our current concepts.</p>\n<p>So why is it that the number of concepts (or words) isn’t just always increasing? A fundamental reason is abstraction. Abstraction takes collections of potentially large numbers of specific things (“tiger”, “lion”, …) and allows them to be described “abstractly” in terms of a more general thing (say, “big cats”). And abstraction is useful if it’s possible to make collective statements about those general things (“all big cats have…”), in effect providing a consistent “higher-level” way of thinking about things. </p>\n<p>If we imagine concepts as being associated with particular pockets of reducibility, the phenomenon of abstraction is then a reflection of the existence of networks of these pockets. And, yes, such networks can themselves show computational irreducibility, which can then have its own pockets of reducibility, etc. </p>\n<p>So what about (artificial) neural nets? It’s routine to “look inside” these, and for example see the possible patterns of activation at a given layer based on a range of possible (“real-world”) inputs. We can then think of these patterns of activation as <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#the-concept-of-embeddings\">forming points in a “feature space”</a>. And typically we’ll be able to see clusters of these points, which we can potentially identify as “emergent concepts” that we can view as having been “discovered” by the neural net (or rather, its training). Normally there won’t be existing words in human languages that correspond to most of these concepts. They represent pockets of reducibility, but not ones that we’ve identified, and that are captured by our typical 30,000 or so words. And, yes, even in today’s neural nets, there can easily be millions of “emergent concepts”.</p>\n<p>But will these be useful abstractions or concepts, or merely “incidental examples of compression” not connected to anything else? The construction of neural nets implies that a pattern of “emergent concepts” at one layer will necessarily feed into the next layer. But the question is really whether the concept can somehow be useful “independently”—not just at this particular place in the neural net.</p>\n<p>And indeed the most obvious everyday use for words and concepts—and language in general—is for communication: for “transferring thoughts” from one mind to another. Within a brain (or a neural net) there are all kinds of complicated patterns of activity, different in each brain (or each neural net). But a fundamental role that concepts, words and language play is to define a way to “package up” certain features of that activity in a form that can be robustly transported between minds, somehow inducing “comparable thoughts” in all of them. </p>\n<p>The transfer from one mind to another can never be precise: in going from the pattern of activity in one brain (or neural net) to the pattern of activity in another, there’ll always be translation involved. But—at least up to a point—one can expect that the “more that’s said” the more faithful a translation can be. </p>\n<p>But what if there’s a bigger brain, with more “emergent concepts” inside? Then to communicate about them at a certain level of precision we might need to use more words—if not a fundamentally richer form of language. And, yes, while dogs seem to understand isolated words (“sit”, “fetch”, …), we, with our larger brains, can deal with compositional language in which we can in effect construct an infinite range of meanings by combining words into phrases, sentences, etc. </p>\n<p>At least as we currently imagine it, language defines a certain model of the world, based on some finite collection of primitives (words, concepts, etc.). The existence of computational irreducibility tells us that such a model can never be complete. Instead, the model has to “approximate things” based on the “network of pockets of reducibility” that the primitives in the language effectively define. And insofar as a bigger brain might in essence be able to make use of a larger network of pockets of reducibility, it can then potentially support a more precise model of the world.</p>\n<p>And it could then be that if we look at such a brain and what it does, it will inevitably seem closer to the kind of “incomprehensible and irreducible computation” that’s characteristic of so many abstract systems, and systems in nature. But it could also be that in being a “brain-like construct” it’d necessarily tap into computational reducibility in such a way that—with the formalism and abstraction we’ve built—we’d still meaningfully be able to talk about what it can do. </p>\n<p>At the outset we might have thought any attempt for us to “understand minds beyond ours” would be like asking a cat to understand algebra. But somehow the universality of the concepts of computation that we now know—with their ability to address the deepest foundations of physics and other fields—makes it seem more plausible we might now be in a position to meaningfully discuss minds beyond ours. Or at least to discuss the rather more concrete question of what brains like ours, but bigger than ours, might be able to do. </p>\n<h2 id=\"how-brains-seem-to-work\">How Brains Seem to Work</h2>\n<p>As we’ve mentioned, at least in a rough approximation, the role of brains is to turn large amounts of sensory input into small numbers of decisions about what to do. But how does this happen? </p>\n<p>Human brains continually receive input from a few million “sensors”, mostly associated with photoreceptors in our eyes and touch receptors in our skin. This input is processed by a total of about 100 billion neurons, each responding in a few milliseconds, and mostly organized into a handful of layers. There are altogether perhaps 100 trillion connections between neurons, many quite long range. At any given moment, a few percent of neurons (i.e. perhaps a billion) are firing. But in the end, all that activity seems to feed into particular structures in the lower part of the brain that in effect “take a majority vote” a few times a second to determine what to do next—in particular with the few hundred “actuators” our bodies have. </p>\n<p>This basic picture seems to be more or less the same in all higher animals. The total number of neurons scales roughly with the number of “input sensors” (or, in a first approximation, the surface area of the animal—i.e. volume<sup>2/3</sup>—which determines the number of touch sensors). The fraction of brain volume that consists of connections (“white matter”) as opposed to main parts of neurons (“gray matter”) increases as a power of the number of neurons. The largest brains—like ours—have a roughly nested pattern of folds that presumably reduce average connection lengths. Different parts of our brains have characteristic functions (e.g. motor control, handling input from our eyes, generation of language, etc.), although there seems to be enough universality that other parts can usually learn to take over if necessary. And in terms of overall performance, animals with smaller brains generally seem to react more quickly to stimuli. </p>\n<p>So what was it that made brains originally arise in biological evolution? Perhaps it had to do with giving animals a way to decide where to go next as they moved around. (Plants, which don’t move around, don’t have brains.) And perhaps it’s because animals can’t “go in more than one direction at once” that brains seem to have the fundamental feature of generating a single stream of decisions. And, yes, this is probably why we have a <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/\">single thread of “conscious experience”</a>, rather than a whole collection of experiences associated with the activities of all our neurons. And no doubt it’s also what we leverage in the construction of language—and in communicating through a one-dimensional sequence of tokens. </p>\n<p>It’s notable how similar our description of brains is to the basic <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">operation of large language models</a>: an LLM processes input from its “context window” by feeding it through large numbers of artificial neurons organized in layers—ultimately taking something like a majority vote to decide what token to generate next. There are differences, however, most notably that whereas brains routinely intersperse learning and thinking, current LLMs separate training from operation, in effect “learning first” and “thinking later”.</p>\n<p>But almost certainly the core capabilities of both brains and neural nets <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">don’t depend much</a> on the details of their biological or architectural structure. It matters that there are many inputs and few outputs. It matters that there’s irreducible computation inside. It matters that the systems are trained on the world as it is. And, finally, it matters how “big” they are, in effect relative to the “number of relevant features of the world”.</p>\n<p>In artificial neural nets, and presumably also in brains, memory is encoded in the<br />\nstrengths (or “weights”) of connections between neurons. And at least in neural nets it seems that the number of tokens (of textual data) that can reasonably be “remembered” is a few times the number of weights. (With current methods, the number of computational operations of training needed to achieve this is roughly the product of the total number of weights and the total number of tokens.) If there are too few weights, what happens is that the <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/#:~:text=pretty%20much%20the%20smallest%20that%20will%20work\">“memory” gets fuzzy</a>, with details of the fuzziness reflecting details of the structure of the network. </p>\n<p>But what’s crucial—for both neural nets and brains—is not so much to remember specifics of training data, but rather to just “<a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#models-for-human-like-tasks\">do something reasonable</a>” for a wide range of inputs, regardless of whether they’re in the training data. Or, in other words, to generalize appropriately from training data.</p>\n<p>But what is “appropriate generalization”? As a practical matter, it tends to be “generalization that aligns with what we humans would do”. And it’s then a remarkable fact that artificial neural nets with fairly simple architectures can successfully do generalizations in a way that’s roughly aligned with human brains. So why does this work? Presumably it’s because there are universal features of “brain-like systems” that are close enough between human brains and neural nets. And once again it’s important to emphasize that what’s happening in both cases seems distinctly weaker than “general computation”. </p>\n<p> A feature of “general computation” is that it can potentially involve unbounded amounts of time and storage space. But both brains and typical neural nets have just a fixed number of neurons. And although both brains and LLMs in effect have an “outer loop” that can “recycle” output to input, it’s limited. </p>\n<p>And at least when it comes to brains, a key feature associated with this is the limit on “working memory”, i.e. memory that can readily be both read and written “in the course of a computation”. Bigger and more developed brains typically seem to support larger amounts of working memory. Adult humans can remember perhaps 5 or 7 “chunks” of data in working memory; for young children, and other animals, it’s less. Size of working memory (as we’ll discuss later) seems to be important in things like language capabilities. And the fact that it’s limited is no doubt one reason we can’t generally “run code in our brains”. </p>\n<p>As we try to reflect on what our brains do, we’re most aware of our stream of conscious thought. But that represents just a tiny fraction of all our neural activity. Most of the activity is much less like “thought” and much more like typical processes in nature, with lots of elements seemingly “doing their own thing”. We might think of this as an “ocean of unconscious neural activity”, from which a “<a href=\"https://writings.stephenwolfram.com/2021/05/the-problem-of-distributed-consensus/\">thread of consensus thought</a>” is derived. Usually—much like in an artificial neural net—it’s difficult to find much regularity in that “unconscious activity”. Though when one trains oneself enough to get to the point of being able to “do something without thinking about it”, that presumably happens by organizing some part of that activity. </p>\n<p>There’s always a question of what kinds of things we can learn. We can’t overcome computational irreducibility. But how broadly can we handle what’s computationally reducible? Artificial neural nets show a certain genericity in their operation: although some specific architectures are more efficient than others, it doesn’t seem to matter much whether the input they’re fed is images or text or numbers, or whatever. And for our brains it’s probably the same—though what we’ve normally experienced, and learned from, are the specific kinds of input the come from our eyes, ears, etc. And from these, we’ve ended up recognizing certain types of regularities—that we’ve then used to guide our actions, set up our environment, etc. </p>\n<p>And, yes, this plugs into certain pockets of computational reducibility in the world. But there’s always further one could go. And how that might work with brains bigger than ours is at the core of what we’re trying to discuss here.</p>\n<h2 id=\"language-and-beyond\">Language and Beyond</h2>\n<p>At some level we can view our brains as serving to take the complexity of the world and extract from it a compressed representation that our finite minds can handle. But what is the structure of that representation? A central aspect of it is that it ignores many details of the original input (like particular configurations of pixels). Or, in other words, it effectively <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">equivalences many different inputs together</a>.</p>\n<p>But how then do we describe that equivalence class? Implementationally, say in a neural net, the equivalence class might <a href=\"https://www.wolframscience.com/nks/p275/\">correspond to an attractor</a> to which many different initial conditions all evolve. In terms of the detailed pattern of activity in the neural net the attractor will typically be very hard to describe. But on a larger scale we can potentially just think of it as some kind of robust construct that represents a class of things—or what in terms of our process of thought we might describe as a “concept”.</p>\n<p>At the lowest level there’s all sorts of complicated neural activity in our brains—most of it mired in computational irreducibility. But the “thin thread of conscious experience” that we extract from this we can for many purposes treat as being made up of higher-level “units of thought”, or essentially “discrete concepts”.</p>\n<p>And, yes, it’s certainly our typical human experience that robust constructs—and particularly ones from which other constructs can be built—will be discrete. In principle one can imagine that there could be things like “robust continuous spaces of concepts” (“cat and dog and everything in between”). But we don’t have anything like the computational paradigm that shows us a consistent universal way that such things could fit together (there’s <a href=\"https://www.wolframscience.com/nks/notes-12-4--continuous-computation/\">no robust analog of computation theory for real numbers</a>, for example). And somehow the success of the computational paradigm—potentially all the way down to the foundations of the physical universe—doesn’t seem to leave much room for anything else.</p>\n<p>So, OK, let’s imagine that we can represent our thread of conscious experience in terms of concepts. Well, that’s close to saying that we’re using language. We’re “packaging up” the details of our neural activity into “robust elements” which we can think of as concepts—and which are represented in language essentially by words. And not only does this “packaging” into language give a robust way for different brains to communicate; it also gives a single brain a robust way to “remember” and “redeploy” thoughts.</p>\n<p>Within one brain one could imagine that one might be able to remember and “think” directly in terms of detailed low-level neural patterns. But no doubt the “neural environment” inside a brain is continually changing (not least because of its stream of sensory input). And so the only way to successfully “preserve a thought” across time is presumably to “package it up” in terms of robust elements, or essentially in terms of language. In other words, if we’re going to be able to consistently “think a particular thought” we probably have to formulate it in terms of something robust—like concepts.</p>\n<p>But, OK, individual concepts are one thing. But language—or at least human language—is based on putting together concepts in structured ways. One might take a noun (“cat”) and qualify it with an adjective (“black”) to form a phrase that’s in effect a finer-grained version of the concept represented by the noun. And in a rough approximation one can think of language as formed from trees of nested phrases like this. And insofar as the phrases are independent in their structure (i.e. “<a href=\"https://www.wolframscience.com/nks/notes-10-12--context-free-languages/\">context free</a>”), we can parse such language by recursively understanding each phrase in turn—with the constraint that we can’t do it if the nesting goes too deep for us to hold the necessary stack of intermediate steps in our working memory.</p>\n<p>An important feature of ordinary human language is that it’s ultimately presented in a sequential way. Even though it may consist of a nested tree of phrases, the words that are the leaves of that tree are spoken or written in a one-dimensional sequence. And, yes, the fact that this is how it works is surely closely connected to the fact that our brains construct a single thread of conscious experience. </p>\n<p>In the actuality of the <a href=\"https://reference.wolfram.com/language/ref/entity/Language.html\">few thousand human languages</a> currently in use, there is considerable superficial diversity, but also considerable fundamental commonality. For example, the same parts of speech (noun, verb, etc.) typically show up, as do concepts like “subject” and “object”. But the details of how words are put together, and how things are indicated, can be fairly different. Sometimes nouns have case endings; sometimes there are separate prepositions. Sometimes verb tenses are indicated by annotating the verb; sometimes with extra words. And sometimes, for example, what would usually be whole phrases can be smooshed together into single words.</p>\n<p>It’s not clear to what extent commonalities between languages are the result of shared history, and to what extent they’re consequences either of the particulars of our human sensory experience of the world, or the particular construction of our brains. It’s not too hard to get <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/#identifying-computational-reducibility\">something like concepts to emerge</a> in experiments on training neural nets to pass data through a “bottleneck” that simulates a “mind-to-mind communication channel”. But how compositionality or grammatical structure might emerge is not clear.</p>\n<p>OK, but so what might change if we had bigger brains? If neural nets are a guide, one obvious thing is that we should be able to deal directly with a larger number of “distinct concepts”, or words. So what consequences would this have? Presumably one’s language would get “grammatically shallower”, in the sense that what would otherwise have had to be said with nested phrases could now be said with individual words. And presumably this would tend to lead to “faster communication”, requiring fewer words. But it would likely also lead to more rigid communication, with less ability to tweak shades of meaning, say by changing just a few words in a phrase. (And it would presumably also require longer training, to learn what all the words mean.)</p>\n<p>In a sense we have a preview of what it’s like to have more words whenever we deal with specialized versions of existing language, aimed say at particular technical fields. There are additional words of “jargon” available, that make certain things “faster to say” (but require longer to learn). And with that jargon comes a certain rigidity, in saying easily only what the jargon says, and not something slightly different. </p>\n<p>So how else could language be different with a bigger brain? With larger working memory, one could presumably have more deeply nested phrases. But what about more sophisticated grammatical structures, say ones that aren’t “context free”, in the sense that different nested phrases can’t be parsed separately? My guess is that this quickly devolves into requiring arbitrary computation—and runs into computational irreducibility. In principle it’s perfectly possible to have any program as the “message” one communicates. But if one has to run the program to “determine its meaning”, that’s in general going to involve computational irreducibility.</p>\n<p>And the point is that with our assumptions about what “brain-like systems” do, that’s something that’s out of scope. Yes, one can construct a system (even with neurons) that can do it. But not with the “single thread of decisions from sensory input” workflow that seems characteristic of brains. (There are finer gradations one could consider—like languages that are <a href=\"https://www.wolframscience.com/nksonline/page-938d/\">context sensitive</a> but don’t require general computation. But the Principle of Computational Equivalence strongly suggests that the separation between nested context-free systems and ones associated with arbitrary computation <a href=\"https://www.wolframscience.com/nks/notes-12-4--intermediate-degrees/\">is very thin</a>, and there doesn’t seem to be any particular reason to expect that the capabilities of a bigger brain would land right there.)</p>\n<p>Said another way: the Principle of Computational Equivalence says it’s easy to have a system that can deal with arbitrary computation. It’s just that such a system is not “brain like” in its behavior; it’s more like a typical system we see in nature. </p>\n<p>OK, but what other “additional features” can one imagine, for even roughly “brain-like” systems? One possibility is to go beyond the idea of a single thread of experience, and to consider a <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/#the-formal-structure-of-multicomputation\">multiway system</a> in which threads of experience can branch and merge. And, yes, this is what we imagine happens at a low level in the physical universe, particularly in connection with <a href=\"https://writings.stephenwolfram.com/2024/10/on-the-nature-of-time/#multiple-threads-of-time\">quantum mechanics</a>. And indeed it’s perfectly possible to imagine, for example, a “quantum-like” LLM system in which one generates a graph of different textual sequences. But just “scaling up the number of neurons” in a brain, without changing the overall architecture, won’t get to this. We have to have a different, multiway architecture. Where we have a “graph of consciousness” rather than a “stream of consciousness”, and where, in effect, we’re “thinking a graph of thoughts”, notably with thoughts themselves being able to branch and merge. </p>\n<p>In our practical use of language, it’s most often communicated in spoken or written form—effectively as a one-dimensional sequence of tokens. But in math, for example, it’s common to have a <a href=\"https://www.stephenwolfram.com/publications/mathematical-notation-past-future/\">certain amount of 2D structure</a>, and in general there are also all sorts of specialized (usually technical) diagrammatic representations in use, often based on using graphs and networks—as we’ll discuss in more detail below. </p>\n<p>But what about general pictures? Normally it’s difficult for us to produce these. But in <a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/\">generative AI systems it’s basically easy</a>. So could we then imagine directly “communicating mental images” from one mind to another? Maybe as a practical matter some neural implant in our brain could aggregate neural signals from which a displayed image could be generated. But is there in fact something coherent that could be extracted from our brains in this way? Perhaps that can only happen after “consensus is formed”, and we’ve reduced things to a much thinner “thread of experience”. Or, in other words, perhaps the only robust way for us to “think about images” is in effect to reduce them to discrete concepts and language-like representations.</p>\n<p>But perhaps if we “had the hardware” to display images directly from our minds it’d be a different story. And it’s sobering to imagine that perhaps the reason cats and dogs don’t appear to have compositional language is just that they don’t “have the hardware” to talk like we do (and it’s too laborious for them to “type with their paws”, etc.). And, by analogy, that if we “had the hardware” for displaying images, we’d discover we could also “think very differently”. </p>\n<p>Of course, in some small ways we do have the ability to “directly communicate with images”, for example in our use of gestures and body language. Right now, these seem like largely ancillary forms of communication. But, yes, it’s conceivable that with bigger brains, they could be more.</p>\n<p>And when it comes to other animals the story can be different. <a href=\"https://www.wolframscience.com/nks/notes-12-10--animal-communication/\">Cuttlefish are notable</a> for dynamically producing elaborate patterns on their skin—giving them in a sense the hardware to “communicate in pictures”. But so far as one can tell, they produce just a small number of distinct patterns—and certainly nothing like a “pictorial generalization of compositional language”. (In principle one could imagine that “generalized cuttlefish” could do things like “dynamically run cellular automata on their skin”, just like all sorts of animals <a href=\"https://www.wolframscience.com/nks/chap-8--implications-for-everyday-systems#sect-8-7--biological-pigmentation-patterns\">“statically” do in the process of growth or development</a>. But to decode such patterns—and thereby in a sense enable “communicating in programs”—would typically require irreducible amounts of computation that are beyond the capabilities of any standard brain-like system.)</p>\n<h2 id=\"sensors-and-actuators\">Sensors and Actuators</h2>\n<p>We humans have raw inputs coming into our brains from a few million sensors distributed across our usual senses of touch, sight, hearing, taste and smell (together with balance, temperature, hunger, etc.). In most cases the detailed sensor inputs are not independent; in a typical visual scene, for example, neighboring pixels are highly correlated. And it doesn’t seem to take many layers of neurons in our brains to distill our typical sensory experience from pure pieces of “raw data” to what we might view as “more independent features”. </p>\n<p>Of course there’ll usually be much more in the raw data than just those features. But the “features” typically correspond to aspects of the data that we’ve “learned are useful to us”—normally connected to pockets of computational reducibility that exist in the environment in which we operate. Are the features we pick out all we’ll ever need? In the end, we typically want to derive a small stream of decisions or actions from all the data that comes in. But how many “intermediate features” do we need to get “good” decisions or actions?</p>\n<p>That really depends on two things. First, what our decisions and actions are like. And second, what our raw data is like. Early in the history of our species, everything was just about “indigenous human experience”: what the natural world is like, and what we can do with our bodies. But as soon as we were dealing with technology, that changed. And in today’s world we’re constantly exposed, for example, to visual input that comes not from the natural world, but, say, from digital displays. </p>\n<p>And, yes, we often try to arrange our “user experience” to align with what’s familiar from the natural world (say by having objects that stay unchanged when they’re moved across the screen). But it doesn’t have to be that way. And indeed it’s easy—even with simple programs—to generate for example visual images very different from what we’re used to. And in many such cases, it’s very hard for us to “tell what’s going on” in the image. Sometimes it’ll just “look too complicated”. Sometimes it’ll seem like it has pieces we should recognize, but we don’t:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/05/sw05192025sensorsimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/05/sw05192025sensorsimg1.png' alt='' title='' width='675' height='270'> </div>\n</p></div>\n<p>When it’s “just too complicated”, that’s often a reflection of computational irreducibility. But when there are pieces we might “think we should recognize”, that can be a reflection of pockets of reducibility we’re just not familiar with. If we imagine a space of possible images—as we can readily produce with generative AI—there will be some that correspond to concepts (and words) we’re familiar with. But the vast majority will effectively lie in “<a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/\">interconcept space</a>”: places where we could have concepts, but don’t, at least yet:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/05/sw05192025sensorsimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/05/sw05192025sensorsimg2a.png' alt='' title='' width='684' height='220'> </div>\n</p></div>\n<p>So what could bigger brains do with all this? Potentially they could handle more features, and more concepts. Full computational irreducibility will always in effect ultimately overpower them. But when it comes to handling pockets of reducibility, they’ll presumably be able to deal with more of them. So in the end, it’s very much as one might expect: a bigger brain should be able to track more things going on, “see more details”, etc. </p>\n<p>Brains of our size seem like they are in effect sufficient for “indigenous human experience”. But with technology in the picture, it’s perfectly possible to “overload” them. (Needless to say, technology—in the form of filtering, data analysis, etc.—can also reduce that overload, in effect taking raw input and bringing our actual experience of it closer to something “indigenous”.)</p>\n<p>It’s worth pointing out that while two brains of a given size might be able to “deal with the same number of features or concepts”, those features or concepts might be different. One brain might have learned to talk about the world in terms of one set of primitives (such as certain basic colors); another in terms of a different set of primitives. But if both brains are sampling “indigenous human experience” in similar environments one can expect that it should be possible to translate between these descriptions—just as it is generally possible to translate between things said in different human languages.</p>\n<p>But what if the brains are effectively sampling “different slices of reality”? What if one’s using technology to convert different physical phenomena to forms (like images) that we can “indigenously” handle? Perhaps we’re sensing different electromagnetic frequencies; perhaps we’re sensing molecular or chemical properties; perhaps we’re sensing something like fluid motion. The kinds of features that will be “useful” may be quite different in these different modalities. Indeed, even something as seemingly basic as the notion of an “object” may not be so relevant if our sensory experience is effectively of continuous fluid motion.</p>\n<p>But in the end, what’s “useful” will depend on what we can do. And once again, it depends on whether we’re dealing with “pure humans” (who can’t, for example, move like octopuses) or with humans “augmented by technology”. And here we start to see an issue that relates to the basic capabilities of our brains.</p>\n<p>As “pure humans”, we have certain “actuators” (basically in the form of muscles) that we can “indigenously” operate. But with technology it’s perfectly possible for us to use quite different actuators in quite different configurations. And as a practical matter, with brains like ours, we may not be able to make them work.</p>\n<p>For example, while humans can control helicopters, they never managed to control quadcopters—at least not <a href=\"https://writings.stephenwolfram.com/2012/10/kids-arduinos-and-quadricopters/\">until digital flight controllers could do most of the work</a>. In a sense there were just too many degrees of freedom for brains like ours to deal with. Should bigger brains be able to do more? One would think so. And indeed one could imagine testing this with artificial neural nets. In millipedes, for example, their actual brains seem to support only a couple of <a href=\"https://www.wolframscience.com/nksonline/page-1011f/\">patterns of motion of their legs</a> (roughly, same phase vs. opposite phase). But one could imagine that with a bigger brain, all sorts of other patterns would become possible. </p>\n<p>Ultimately, there are two issues at stake here. The first is having a brain be able to “independently address” enough actuators, or in effect enough degrees of freedom. The second is having a brain be able to control those degrees of freedom. And for example with mechanical degrees of freedom there are again essentially issues of computational irreducibility. Looking at the space of possible configurations—say of millipede legs—does one effectively just have to trace the path to find out if, and how, <a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-multicomputational-systems/\">one can get from one configuration to another</a>? Or are there instead pockets of reducibility, associated with regularities in the space of configurations, that let one “jump ahead” and figure this out without tracing all the steps? It’s those pockets of reducibility that brains can potentially make use of.</p>\n<p>When it comes to our everyday “indigenous” experience of the world, we are used to certain kinds of computational reducibility, associated for example with familiar natural laws, say about motion of objects. But what if we were dealing with different experiences, <a href=\"https://www.wolframscience.com/nks/notes-10-13--biological-forms-of-perception/\">associated with different senses</a>? </p>\n<p>For example, imagine (as with dogs) that our sense of smell was better developed than our sense of sight—as reflected by more nerves coming into our brains from our noses than our eyes. Our description of the world would then be quite different, based for example not on geometry revealed by the line-of-sight arrival of light, but instead by the delivery of odors through fluid motion and diffusion—not to mention the probably-several-hundred-dimensional space of odors, compared to the red, green, blue space of colors. Once again there would be features that could be identified, and “concepts” that could be defined. But those might only be useful in an environment “built for smell” rather than one “built for sight”. </p>\n<p>And in the end, how many concepts would be useful? I don’t think we have any way to know. But it certainly seems as if one can be a successful “smell-based animal” with a smaller brain (presumably supporting fewer concepts) than one needs as a successful “sight-based animal”. </p>\n<p>One feature of “natural senses” is that they tend to be spatially localized: an animal basically senses things only where it is. (We’ll discuss the case of social organisms later.) But what if we had access to a distributed array of sensors—say associated with IoT devices? The “effective laws of nature” that one could perceive would then be different. Maybe there would be regularities that could be captured by a small number of concepts, but it seems more likely that the story would be more complicated, and that in effect one would “need a bigger brain” to be able to keep track of what’s going on, and make use of whatever pockets of reducibility might exist.</p>\n<p>There are somewhat similar issues if one imagines changing the timescales for sensory input. Our perception of space, for example, depends on the fact that light travels fast enough that in the milliseconds it takes our brain to register the input, we’ve already received light from everything that’s around us. But if our brains operated a million times faster (as digital electronics does) we’d instead be registering individual photons. And while our brains might aggregate these to something like what we ordinarily perceive, there may be all sorts of other (e.g. quantum optics) effects that would be more obvious. </p>\n<h2 id=\"abstraction\">Abstraction</h2>\n<p>The more abstractly we try to think, the harder it seems to get. But would it get easier if we had bigger brains? And might there perhaps be fundamentally <a href=\"https://writings.stephenwolfram.com/2025/01/who-can-understand-the-proof-a-window-on-formalized-mathematics/#what-about-a-higher-level-abstraction\">higher levels of abstraction</a> that we could reach—but only if we had bigger brains. </p>\n<p>As a way to approach such questions, let’s begin by talking a bit about the history of the phenomenon of abstraction. We might already say that basic perception involves some abstraction, capturing as it does a filtered version of the world as it actually is. But perhaps we reach a different level when we start to ask “what if?” questions, and to imagine how things in the world could be different than they are. </p>\n<p>But somehow when it comes to us humans, it seems as if the greatest early leap in abstraction was the invention of language, and the explicit delineation of concepts that could be quite far from our direct experience. The earliest written records tend to be rather matter of fact, mostly recording as they do events and transactions. But already there are plenty of signs of abstraction. <a href=\"https://writings.stephenwolfram.com/2021/05/how-inevitable-is-the-concept-of-numbers/\">Numbers independent of what they count.</a> Things that should happen in the future. The concept of money. </p>\n<p>There seems to be a certain pattern to the development of abstraction. One notices that some category of things one sees many times can be considered similar, then one “packages these up” into a concept, often described by a word. And in many cases, there’s a certain kind of self amplification: once one has a word for something (as a modern example, say “blog”), it becomes easier for us to think about the thing, and we tend to see it or make it more often in the world around us. But what really makes abstraction take off is when we start building a whole tower of it, with one abstract concept recursively being based on others.</p>\n<p>Historically this began quite slowly. And perhaps it was seen first in theology. There were glimmerings of it in things like early (syllogistic) logic, in which one started to be able to talk about the form of arguments, independent of their particulars. And then there was mathematics, where computations could be done just in terms of numbers, independent of where those numbers came from. And, yes, while there were tables of “raw computational results”, numbers were usually discussed in terms of what they were numbers of. And indeed when it came to things like measures of weight, it took until surprisingly modern times for there to be an absolute, abstract notion of weight, independent of whether it was a weight of figs or of wool. </p>\n<p>The development of algebra in the early modern period can be considered an important step forward in abstraction. Now there were formulas that could be manipulated abstractly, without even knowing what particular numbers <em>x</em> stood for. But it would probably be fair to say that there was a <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#some-historical-and-philosophical-background\">major acceleration in abstraction in the 19th century</a>—with the <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-and-the-story-of-computation/#what-is-mathematics-and-logic-made-of\">development of formal systems</a> that could be discussed in “purely symbolic form” independent of what they might (or might not) “actually represent”. </p>\n<p>And it was from this tradition that <a href=\"https://www.wolframscience.com/nks/notes-11-3--history-of-universality/\">modern notions of computation emerged</a> (and indeed particularly ones associated with symbolic computation that I personally have extensively used). But the most obvious area in which towers of abstraction have been built is mathematics. One might start with numbers (that could count things). But soon one’s on to variables, functions, spaces of functions, category theory—and a zillion other constructs that abstractly build on each other.</p>\n<p>The great value of abstraction is that it allows one to think about large classes of things all at once, instead of each separately. But how do those abstract concepts fit together? The issue is that often it’s in a way that’s very remote from anything about which we have direct experience from our raw perception of the world. Yes, we can define concepts about transfinite numbers or higher categories. But they don’t immediately relate to anything we’re familiar with from our everyday experience. </p>\n<p>As a practical matter one can often get a sense of how high something is on the tower of abstraction by seeing how much one has to explain to build up to it from “raw experiential concepts”. Just sometimes it turns out that actually, once one hears about a certain seemingly “highly abstract” concept, one can actually explain it surprisingly simply, without going through the whole historical chain that led to it. (A notable example of this is the concept of universal computation—which arose remarkably late in human intellectual history, but is now quite easy to explain, albeit particularly given its actual widespread embodiment in technology.) But the more common case is that there’s no choice but to explain a whole tower of concepts.</p>\n<p>At least in my experience, however, when one actually thinks about “highly abstract” things, one does it by making analogies to more familiar, more concrete things. The analogies may not be perfect, but they provide scaffolding which allows our brains to take what would otherwise be quite inaccessible steps. </p>\n<p>At some level any abstraction is a reflection of a pocket of computational reducibility. Because if a useful abstraction can be defined, what it means is that it’s possible to say something in a “summarized” or reduced way, in effect “jumping ahead”, without going through all the computational steps or engaging with all the details. And one can then think of towers of abstraction as being like networks of pockets of computational reducibility. But, yes, it can be hard to navigate these. </p>\n<p>Underneath, there’s lots of computational irreducibility. And if one is prepared to “go through all the steps” one can often “get to an answer” without all the “conceptual difficulty” of complex abstractions. But while computers can often readily “go through all the steps”, brains can’t. And that’s in a sense why we have to use abstraction. But inevitably, even if we’re using abstraction, and the pockets of computational reducibility associated with it, there’ll be shadows of the computational irreducibility underneath. And in particular, if we try to “explore everything”, our network of pockets of reducibility will inevitably “get complicated”, and ultimately also be mired in computational irreducibility, albeit with “higher-level” constructs than in the computational irreducibility underneath. </p>\n<p>No finite brain will ever be able to “go all the way”, but it starts to seem likely that a bigger brain will be able to “reach further” in the network of abstraction. But what will it find there? How does the character of abstraction change when we take it further? We’ll be able to discuss this a bit more concretely when we talk about computational language below. But perhaps the main thing to say now is that—at least in my experience—most higher abstractions don’t feel as if they’re “structurally different” once one understands them. In other words, most of the time, it seems as if the same patterns of thought and reasoning that one’s applied in many other places can be applied there too, just to different kinds of constructs. </p>\n<p>Sometimes, though, there seem to be exceptions. <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-2--the-need-for-a-new-intuition\">Shocks to intuition</a> that seem to separate what one’s now thinking about from anything one’s thought before. And, for example, for me this happened when I started <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/\">looking broadly at the computational universe</a>. I had always assumed that simple rules would lead to simple behavior. But many years ago I discovered that in the computational universe this isn’t true (hence computational irreducibility). And this led to a whole different paradigm for thinking about things. </p>\n<p>It feels a bit like in <a href=\"https://www.wolframscience.com/metamathematics/\">metamathematics</a>. Where one can imagine one type of abstraction associated with different constructs out of which to form theorems. But where somehow there’s another level associated with different ways to build new theorems, or indeed whole spaces of theorems. Or to build proofs from proofs, or proofs from proofs of proofs, etc. But the remarkable thing is that there seems to be an ultimate construct that encompasses it all: <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">the ruliad</a>. </p>\n<p>We can describe the ruliad as the entangled limit of all possible computations. But we can also describe it as the limit of all possible abstractions. And it seems to lie underneath all physical reality, as well as all possible mathematics, etc. But, we might ask, how do brains relate to it?</p>\n<p>Inevitably, it’s full of computational irreducibility. And looked at as a whole, brains can’t get far with it. But the key idea is to think about how brains as they are—with all their various features and limitations—will “parse” it. And what I’ve argued is that what “brains as they are” will perceive about the ruliad are the core laws of physics (and mathematics) as we know them. In other words, it’s because brains are the way they are that we perceive the laws of physics that we perceive.</p>\n<p>Would it be different for bigger brains? Not if they’re the “same kind of brains”. Because <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">what seems to matter for the core laws of physics are really just two properties of observers</a>. First, that they’re computationally bounded. And second, that they believe they are persistent in time, and have a single thread of experience through time. And both of these seem to be core features of what makes brains “brain-like”, rather than just arbitrary computational systems. </p>\n<p>It’s a remarkable thing that just these features are sufficient to make core laws of physics inevitable. But if we want to understand more about the physics we’ve constructed—and the laws we’ve deduced—we probably have to understand more about what we’re like as observers. And indeed, <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/#what-we-assume-about-ourselves\">as I’ve argued elsewhere</a>, even our physical scale (much bigger than molecules, much smaller than the whole universe) is for example important in giving us the particular experience (and laws) of physics that we have. </p>\n<p>Would this be different with bigger brains? Perhaps a little. But anything that something brain-like can do pales in comparison to the computational irreducibility that exists in the ruliad and in the natural world. Nevertheless, with every new pocket of computational reducibility that’s reached we get some new abstraction about the world, or in effect, some new law about how the world works. </p>\n<p>And as a practical matter, each such abstraction can allow us to build a whole collection of new ways of thinking about the world, and making things in the world. It’s challenging to trace this arc. Because in a sense it’ll all be about “things we never thought to think about before”. <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/#will-there-be-anything-left-for-the-humans-to-do\">Goals we might define for ourselves</a> that are built on a tower of abstraction, far away from what we might think of as “indigenous human goals”.</p>\n<p>It’s important to realize that there won’t just be one tower of abstraction that can be built. There’ll inevitably be an infinite network of pockets of computational reducibility, with each path leading to a different specific tower of abstraction. And indeed the abstractions we have pursued reflect the particular arc of human intellectual history. Bigger brains—or AIs—have many possible directions they can go, each one defining a different path of history.</p>\n<p>One question to ask is to what extent reaching higher levels of abstraction is a matter of education, and to what extent it requires additional intrinsic capabilities of a brain. It is, I suspect, a mixture. Sometimes it’s really just a question of knowing “where that pocket of reducibility is”, which is something we can learn from education. But sometimes it’s a question of navigating a network of pockets, which may only be possible when brains reach a certain level of “computational ability”. </p>\n<p>There’s another thing to discuss, <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/#preparing-for-an-ai-world\">related to education</a>. And that’s the fact that over time, more and more “distinct pieces of knowledge” get built up in our civilization. There was perhaps a time in history when a brain of our size could realistically commit to memory at least the basics of much of that knowledge. But today that time has long passed. Yes, abstraction in effect compresses what one needs to know. But the continual addition of new and seemingly important knowledge, across countless specialties, makes it impossible for brains of our size to keep up.</p>\n<p>Plenty of that knowledge is, though, quite siloed in different areas. But sometimes there are “grand analogies” to make—say <a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/#fitness-functions-based-on-aspect-ratio\">pulling an idea from relativity theory and applying it to biological evolution</a>. In a sense such analogies reveal new abstractions—but to make them requires knowledge that spans many different areas. And that’s a place where bigger brains—or AIs—can potentially do something that’s in a fundamental way “beyond us”. </p>\n<p>Will there always be such “grand analogies” to make? The general growth of knowledge is inevitably a computationally irreducible process. And within it there will inevitably be pockets of reducibility. But how often in practice will one actually encounter “long-range connections” across “knowledge space”? As a specific example one can look at metamathematics, where such connections are manifest in theorems that <a href=\"https://www.wolframscience.com/metamathematics/uniformity-and-motion-in-metamathematical-space/\">link seemingly different areas of mathematics</a>. And this example leads one to realize that at some deep level grand analogies are in a sense inevitable. In the context of the ruliad, one can think of different domains of knowledge as corresponding to different parts. But the nature of the ruliad—encompassing as it does everything that is computationally possible—inevitably imbues it with a certain homogeneity, which implies that (as the Principle of Computational Equivalence might suggest) there must ultimately be a correspondence between different areas. In practice, though, this correspondence may be at a very “atomic” (or “formal”) level, far below the kinds of descriptions (based on pockets of reducibility) that we imagine brains normally use.</p>\n<p>But, OK, will it always take an “expanding brain” to keep up with the “expanding knowledge” we have? Computational irreducibility guarantees that there’ll always in principle be “new knowledge” to be had—separated from what’s come before by irreducible amounts of computation. But then there’s the question of <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/\">whether in the end we’ll care about it</a>. After all, it could be that the knowledge we can add is so abstruse that it will never affect any practical decisions we have to make. And, yes, to some extent that’s true (which is why only some tiny fraction of the Earth’s population will care about what I’m writing here). But another consequence of computational irreducibility is that there will always be “surprises”—and those can eventually “push into focus” even what at first seems like arbitrarily obscure knowledge. </p>\n<h2 id=\"computational-language\">Computational Language</h2>\n<p>Language in general—and compositional language in particular—is arguably the greatest invention of our species. But is it somehow “the top”—the highest possible representation of things? Or if, for example, we had bigger brains, is there something beyond it that we could reach? </p>\n<p>Well, in some very formal sense, yes, compositional language (at least in idealized form) is “the top”. Because—at least if it’s allowed to include utterances of any length—then in some sense it can in principle encode arbitrary, <a href=\"https://www.wolframscience.com/nks/chap-11--the-notion-of-computation/\">universal computations</a>. But this really isn’t true in any useful sense—and indeed to apply ordinary compositional language in this way would require doing computationally irreducible computations.</p>\n<p>So we return to the question of what might in practice lie beyond ordinary human language. I wondered about this for a long time. But in the end I realized that the most important clue is in a sense right in front of me: the <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">concept of computational language</a>, that I’ve spent much of my life exploring. </p>\n<p>It’s worth saying at the outset that the way computational language plays out for computers and for brains is somewhat different, and in some respects complementary. In computers you might specify something as a <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> symbolic expression, and then the “main action” is to evaluate this expression, potentially running a long computation to find out what the expression evaluates to.</p>\n<p>Brains aren’t set up to do long computations like this. For them a Wolfram Language expression is something to use in effect as a “representation of a thought”. (And, yes, that’s an important distinction between the computational language concept of Wolfram Language, and standard “programming languages”, which are intended purely as a way to tell a computer what to do, not a way to represent thoughts.)</p>\n<p>So what kinds of thoughts can we readily represent in our computational language? There are ones involving explicit numbers, or mathematical expressions. There are ones involving cities and chemicals, and other real-world entities. But then there are higher-level ones, that in effect describe more abstract structures.</p>\n<p>For example, there’s <tt><a href=\"http://reference.wolfram.com/language/ref/NestList.html\">NestList</a></tt>, which gives the result of nesting any operation, here named <em>f</em>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/05/sw05192025computationalimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/05/sw05192025computationalbimg1.png' alt='' title='' width='458' height='44'> </div>\n</p></div>\n<p>At the outset, it’s not obvious that this would be a useful thing to do. But in fact it’s a <a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/27-applying-functions-repeatedly.html\">very successful abstraction</a>: there are lots of functions <em>f</em> for which one wants to do this.</p>\n<p>In the development of ordinary human language, words tend to get introduced when they’re useful, or, in other words, when they express things one often wants to express. But somehow in human language the words one gets tend to be more concrete. Maybe they describe something that directly happens to objects in the world. Maybe they describe our impression of a human mental state. Yes, one can make rather vague statements like “I’m going to do something to someone”. But human language doesn’t normally “go meta”, doing things like <tt>NestList</tt> where one’s saying that one wants to take some “direct statement” and in effect “work with the statement”. In some sense, human language tends to “work with data”, applying a simple analog of code to it. Our computational language can “work with code” as “raw material”.</p>\n<p>One can think about this as a “higher-order function”: a function that operates not on data, but on functions. And one can keep going, dealing with functions that operate on functions that operate on functions, and so on. And at every level one is increasing the generality—and abstraction—at which one is working. There may be many specific functions (a bit analogous to verbs) that operate on data (a bit analogous to nouns). But when we talk about operating on functions themselves we can potentially have just a single function (like <tt>NestList</tt>) that operates, quite generally, on many functions. In ordinary language, we might call such things “metaverbs”, but they aren’t something that commonly occurs.</p>\n<p>But what makes them possible in computational language? Well, it’s taking the computational paradigm seriously, and representing everything in computational terms: objects, actions, etc. In Wolfram Language, it’s that we can represent <a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/33-expressions-and-their-structure.html\">everything as a symbolic expression</a>. Arrays of numbers (or countries, or whatever) are symbolic expressions. Graphics are symbolic expressions. Programs are symbolic expressions. And so on. </p>\n<p>And given this uniformity of representation it becomes feasible—and natural—to do higher-order operations, that in effect manipulate symbolic structure without being concerned about what the structure might represent. At some level we can view this as leading to the ultimate abstraction embodied in the ruliad, where in a sense “everything is pure structure”. But in practice in Wolfram Language we try to <a href=\"https://writings.stephenwolfram.com/2010/10/the-poetry-of-function-naming/\">“anchor” what we’re doing to known concepts</a> from ordinary human language—so that we use names for things (like <tt>NestList</tt>) that are derived from common English words.</p>\n<p>In some formal sense this isn’t necessary. Everything can be “purely structural”, as it is not only in the ruliad but also in <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/\">constructs like combinators</a>, where, say, the operation of addition can be represented by:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/05/sw05192025computationalimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/05/sw05192025computationalimg2.png' alt='' title='' width='232' height='13'> </div>\n</p></div>\n<p>Combinators have been around for more than a century. But they are almost <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-and-the-story-of-computation/\">impenetrably difficult for most humans to understand</a>. Somehow they involve too much “pure abstraction”, not anchored to concepts we “have a sense of” in our brains. </p>\n<p>It’s been interesting for me to observe over the years what it’s taken for people (including myself) to come to terms with the kind of higher-order constructs that exist in the Wolfram Language. The typical pattern is that over the course of months or years one gets used to lots of specific cases. And only after that is one able—often in the end rather quickly—to “get to the next level” and start to use some generalized, higher-order construct. But normally one can in effect only “go one level at a time”. After one groks one level of abstraction, that seems to have to “settle” for a while before one can go on to the next one.</p>\n<p>Somehow it seems as if one is gradually “feeling out” a certain amount of computational irreducibility, to learn about a new pocket of reducibility, that one can eventually use to “think in terms of”. </p>\n<p>Could “having a bigger brain” speed this up? Maybe it’d be useful to be able to remember more cases, and perhaps get more into “working memory”. But I rather suspect that combinators, for example, are in some sense fundamentally beyond all brain-like systems. It’s much as the Principle of Computational Equivalence suggests: one quickly “ascends” to things that are as computationally sophisticated as anything—and therefore inevitably involve computational irreducibility. There are only certain specific setups that remain within the computationally bounded domain that brain-like systems can deal with.</p>\n<p>Of course, even though they can’t directly “run code in their brains”, humans—and LLMs—can perfectly well <a href=\"https://www.wolfram.com/resources/tools-for-AIs\">use Wolfram Language as a tool</a>, getting it to actually run computations. And this means they can readily “observe phenomena” that are computationally irreducible. And indeed in the end it’s very much the same kind of thing observing such phenomena in the abstract computational universe, and in the “real” physical universe. And the point is that in both cases, brain-like systems will pull out only certain features, essentially corresponding to pockets of computational reducibility. </p>\n<p>How do things like higher-order functions relate to this? At this point it’s not completely clear. Presumably in at least some sense there are hierarchies of higher-order functions that capture certain kinds of regularities that can be thought of as associated with networks of computational reducibility. And it’s conceivable that category theory and its higher-order generalizations are relevant here. In category theory one imagines applying sequences of functions (“morphisms”) and it’s a foundational assumption that the effect of any sequence of functions can also be represented by just a single function—which seems tantamount to saying that one can always “jump ahead”, or in other words, that everything one’s dealing with is computationally reducible. Higher-order category theory then effectively extends this to higher-order functions, but always with what seem like assumptions of computational reducibility.</p>\n<p>And, yes, this all seems highly abstract, and difficult to understand. But does it really need to be, or is there some way to “bring it down” to a level that’s close to everyday human thinking? It’s not clear. But in a sense the core art of computational language design (that I’ve <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\">practiced so assiduously</a> for nearly half a century) is precisely to take things that at first might seem abstruse, and somehow cast them into an accessible form. And, yes, this is something that’s about as intellectually challenging as anything—because in a sense it involves continually trying to “figure out what’s really going on”, and in effect “drilling down” to get to the foundations of everything. </p>\n<p>But, OK, when one gets there, how simple will things be? Part of that depends on how much computational irreducibility is left when one reaches what one considers to be “the foundations”. And part in a sense depends on the extent to which one can “find a bridge” between the foundations and something that’s familiar. Of course, what’s “familiar” can change. And indeed over the four decades that I’ve been developing the Wolfram Language quite a few things (particularly in areas like functional programming) that at first seemed abstruse and unfamiliar have begun to seem more familiar. And, yes, it’s taken the collective development and dissemination of the relevant ideas to achieve that. But now it “just takes education”; it doesn’t “take a bigger brain” to deal with these things.</p>\n<p>One of the core features of the Wolfram Language is that it represents everything as a symbolic expression. And, yes, symbolic expressions are formally able to represent any kind of computational structure. But beyond that, the important point is that they’re somehow set up to <a href=\"https://www.wolframscience.com/nks/chap-10--processes-of-perception-and-analysis#sect-10-12--human-thinking\">be a match for how brains work</a>. </p>\n<p>And in particular, symbolic expressions can be thought of “grammatically” as consisting of nested functions that form a tree-like structure; effectively a more precise version of the typical kind of grammar that we find in human language. And, yes, just as we manage to understand and generate human language with a limited working memory, so (at least at the grammatical level) we can do the same thing with computational language. In other words, in dealing with Wolfram Language we’re leveraging our faculties with human language. And that’s why Wolfram Language can serve as such an effective bridge between the way we think about things, and what’s computationally possible.</p>\n<p>But symbolic expressions represented as trees aren’t the only conceivable structures. It’s also possible to have symbolic expressions where the elements are nodes on a graph, and the graph can even have loops in it. Or one can go further, and start talking, for example, about the <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#what-is-space\">hypergraphs that appear in our Physics Project</a>. But the point is that brain-like systems have a hard time processing such structures. Because to keep track of what’s going on they in a sense have to keep track of multiple “threads of thought”. And that’s not something individual brain-like systems as we current envision them can do. </p>\n<h2 id=\"many-brains-together-the-formation-of-society\">Many Brains Together: The Formation of Society</h2>\n<p>As we’ve discussed several times here, it seems to be a key feature of brains that they create a single “thread of experience”. But what would it be like to have multiple threads? Well, we actually have a very familiar example of that: what happens when we have a whole collection of people (or other animals).</p>\n<p>One could imagine that biological evolution might have produced animals whose brains maintain multiple simultaneous threads of experience. But somehow it has ended up instead restricting each animal to just one thread of experience—and getting multiple threads by having multiple animals. (Conceivably creatures like octopuses may actually in some sense support multiple threads within one organism.) </p>\n<p>Within a single brain it seems important to always “come to a single, definite conclusion”—say to determine where an animal will “move next”. But what about in a collection of organisms? Well, there’s still some kind of coordination that will be important to the fitness of the whole population—perhaps even something as direct as moving together as a herd or flock. And in a sense, just as all those different neuron firings in one brain get collected to determine a “final conclusion for what to do”, so similarly the conclusions of many different brains have to be <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/#governance-in-an-ai-world\">collected to determine a coordinated outcome</a>.</p>\n<p>But how can a coordinated outcome arise? Well, there has to be communication of some sort between organisms. Sometimes it’s rather passive (just watch what your neighbor in a herd or flock does). Sometimes it’s something more elaborate and active—like language. But is that the best one can do? One might imagine that there could be some kind of “telepathic coordination”, in which the raw pattern of neuron firings is communicated from one brain to another. But as we’ve argued, such communication cannot be expected to be robust. To achieve robustness, one must “package up” all the internal details into some standardized form of communication (words, roars, calls, etc.) that one can expect can be “faithfully unpacked” and in effect “understood” by other, suitably similar brains. </p>\n<p>But it’s important to realize that the very possibility of such standardized communication in effect requires coordination. Because somehow what goes on in one brain has to be aligned with what goes on in another. And indeed the way that’s maintained is precisely through continual communication. </p>\n<p>So, OK, how might bigger brains affect this? One possibility is that they might enable more complex social structures. There are plenty of animals with fairly small brains that successfully form “all do the same thing” flocks, herds and the like. But the larger brains of primates seem to allow more complex “tribal” structures. Could having a bigger brain let one successfully maintain a larger social structure, in effect remembering and handling larger numbers of social connections? Or could the actual forms of these connections be more complex? While human social connections seem to be at least roughly captured by social networks represented as ordinary graphs, maybe bigger brains would for example routinely require hypergraphs.</p>\n<p>But in general we can say that language—or standardized communication of some form—is deeply connected to the existence of a “coherent society”. For without being able to exchange something like language there’s no way to align the members of a potential society. And without coherence between members something like language won’t be useful. </p>\n<p>As in so many other situations, one can expect that the detailed interactions between members of a society will show all sorts of computational irreducibility. And insofar as one can identify “the will of society” (or, for that matter, the “tide of history”), it represents a pocket of computational reducibility in the system.</p>\n<p>In human society there is a considerable tendency (though it’s often not successful) to try to maintain a single “thread of society”, in which, at some level, everyone is supposed to act more or less the same. And certainly that’s an important simplifying feature in allowing brains like ours to “navigate the social world”. Could bigger brains do something more sophisticated? As in other areas, one can imagine a whole network of regularities (or pockets of reducibility) in the structure of society, perhaps connected to a whole tower of “higher-order social abstractions”, that only brains bigger than ours can comfortably deal with. (“Just being friends” might be a story for the “small brained”. With bigger brains one might instead have patterns of dependence and connectivity that can only be represented in complicated graph theoretic ways.)</p>\n<h2 id=\"minds-beyond-ours\">Minds beyond Ours</h2>\n<p>We humans have a tremendous tendency to think—or at least hope—that our minds are somehow “at the top” of what’s possible. But with what we know now about computation and how it operates in the natural world it’s pretty <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-12--historical-perspectives\">clear this isn’t true</a>. And indeed it seems as if it’s precisely a limitation in the “computational architecture” of our minds—and brains—that leads to that most cherished feature of our existence that we <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/\">characterize as “conscious experience”</a>. </p>\n<p>In the natural world at large, computation is in some sense happening quite uniformly, everywhere. But our brains seem to be set up to do computation in a more directed and more limited way—taking in large amounts of sensory data, but then filtering it down to a small stream of actions to take. And, yes, one can remove this “limitation”. And while the result may lead to more computation getting done, it doesn’t lead to something that’s “a mind like ours”.</p>\n<p>And indeed in what we’ve done here, we’ve tended to be very conservative in how we imagine “extending our minds”. We’ve mostly just considered what might happen if our brains were scaled up to have more neurons, while basically maintaining the same structure. (And, yes, animals physically bigger than us already have larger brains—as did Neanderthals—but what we really need to look at is size of brain relative to size of the animal, or, in effect “amount of brain for a given amount of sensory input”.)</p>\n<p>A certain amount about what happens with different scales of brains is already fairly clear from looking at different kinds of animals, and at things like their apparent lack of human-like language. But now that we have artificial neural nets that do remarkably human-like things we’re in a position to get a more systematic sense of what different scales of “brains” can do. And indeed we’ve seen a sequence of “capability thresholds” passed as neural nets get larger.</p>\n<p>So what will bigger brains be able to do? What’s fairly straightforward is that they’ll presumably be able to take larger amounts of sensory input, and generate larger amounts of output. (And, yes, the sensory input could come from existing modalities, or new ones, and the outputs could go to existing “actuators”, or new ones.) As a practical matter, the more “data” that has to be processed for a brain to “come to a decision” and generate an output, the slower it’ll probably be. But as brains get bigger, so presumably will the size of their working memory—as well as the number of distinct “concepts” they can “distinguish” and “remember”. </p>\n<p>If the same overall architecture is maintained, there’ll still be just a single “thread of experience”, associated with a single “thread of communication”, or a single “stream of tokens”. At the size of brains we have, we can deal with compositional language in which “concepts” (represented, basically, as words) can have at least a certain depth of qualifiers (corresponding, say, to adjectival phrases). As brain size increases, we can expect there can both be more “raw concepts”—allowing fewer qualifiers—as well as more working memory to deal with more deeply nested qualifiers. </p>\n<p>But is there something qualitatively different that can happen with bigger brains? Computational language (and particularly my experience with the Wolfram Language) gives some indications, the most notable of which is the idea of “going meta” and using “higher-order constructs”. Instead of, say, operating directly on “raw concepts” with (say, “verb-like”) “functions”, we can imagine higher-order functions that operate on functions themselves. And, yes, this is something of which we see powerful examples in the Wolfram Language. But it feels as if we could somehow go further—and make this more routine—if our brains in a sense had “more capacity”.</p>\n<p>To “go meta” and “use higher-order constructs” is in effect a story of abstraction—and of taking many disparate things and abstracting to the point where one can “talk about them all together”. The world at large is full of complexity—and computational irreducibility. But in essence what makes “minds like ours” possible is that there are pockets of computational reducibility to be found. And those pockets of reducibility are closely related to being able to successfully do abstraction. And as we build up towers of abstraction we are in effect navigating through networks of pockets of computational reducibility. </p>\n<p>The progress of knowledge—and the fact that we’re educated about it—lets us get to a certain level of abstraction. And, one suspects, the more capacity there is in a brain, the further it will be able to go. </p>\n<p>But where will it “want to go”? The world at large—full as it is with computational irreducibility, along with infinite numbers of pockets of reducibility—leaves infinite possibilities. And it is largely the coincidence of our particular history that defines the path we have taken. </p>\n<p>We often identify our “sense of purpose” with the path we will take. And perhaps the definiteness of our belief in purpose is related to the particular feature of brains that leads us to concentrate “everything we’re thinking” down into just a single stream of decisions and action. </p>\n<p>And, yes, as we’ve discussed, one could in principle imagine “multiway minds” with multiple “threads of consciousness” operating at once. But we humans (and individual animals in general) don’t seem to have those. Of course, in collections of humans (or other animals) there are still inevitably multiple “threads of consciousness” —and it’s things like language that “knit together” those threads to, for example, make a coherent society.</p>\n<p>Quite what that “knitting” looks like might change as we scale up the size of brains. And so, for example, with bigger brains we might be able to deal with “higher-order social structures” that would seem alien and incomprehensible to us today.</p>\n<p>So what would it be like to interact with a “bigger brain”? Inside, that brain might effectively use many more words and concepts than we know. But presumably it could generate at least a rough (“explain-like-I’m-5”) approximation that we’d be able to understand. There might well be all sorts of abstractions and “higher-order constructs” that we are basically blind to. And, yes, one is reminded of something like a dog listening to a human conversation about philosophy—and catching only the occasional “sit” or “fetch” word. </p>\n<p>As we’ve discussed several times here, if we remove our restriction to “brain-like” operation (and in particular to deriving a small stream of decisions from large amounts of sensory input) we’re thrown into the domain of general computation, where computational irreducibility is rampant, and we can’t in general expect to say much about what’s going on. But if we maintain “brain-like operation”, we’re instead in effect navigating through “networks of computational reducibility”, and we can expect to talk about things like concepts, language and towers of abstraction.</p>\n<p>From a foundational point of view, we can imagine any mind as in effect being at a particular place in <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">the ruliad</a>. When minds communicate, they are effectively exchanging the rulial analog of particles—robust concepts that are somehow unchanged as they propagate within the ruliad. So what would happen if we had bigger brains? In a sense it’s a surprisingly “mechanical” story: a bigger brain—encompassing more concepts, etc.—in effect just occupies a larger region of rulial space. And the presence of abstraction—perhaps learned from a whole arc of intellectual history—can lead to more expansion in rulial space. </p>\n<p>And in the end it seems that “minds beyond ours” can be characterized by how large the regions of the ruliad they occupy are. (Such minds are, in some very literal rulial sense, more “broad minded”.) So what is the limit of all this? Ultimately, it’s a “mind” that spans the whole ruliad, and in effect incorporates all possible computations. But in some fundamental sense this is not a mind like ours, not least because by “being everything” it “becomes nothing”—and one can no longer identify it as having a coherent “thread of individual existence”.</p>\n<p>And, yes, the overall thrust of what we’ve been saying applies just as well to “AI minds” as to biological ones. If we remove restrictions like being set up to generate the next token, we’ll be left with a neural net that’s just “doing computation”, with no obvious “mind-like purpose” in sight. But if we make neural nets do typical “brain-like” tasks, then we can expect that they too will find and navigate pockets of reducibility. We may well not recognize what they’re doing. But insofar as we can, then inevitably we’ll mostly be sampling the parts of “minds beyond ours” that are aligned with “minds like ours”. And it’ll take progress in our whole human intellectual edifice to be able to fully appreciate what it is that minds beyond ours can do.</p>\n<p style='font-size:90%'><i>Thanks for recent discussions about topics covered here in particular to Richard Assar, Joscha Bach, Kovas Boguta, Thomas Dullien, Dugan Hammock, Christopher Lord, Fred Meinberg, Nora Popescu, Philip Rosedale, Terry Sejnowski, Hikari Sorensen, and James Wiles.</i></p>\n",

And over the course of years we’ll see the results of successive innovations. But most of the time those innovations won’t stay within one particular domain—say shapes of bicycle frames. Rather they’ll keep on pulling in innovations from other domains—say, new materials or new manufacturing techniques. But if we want to get closer to the study of the pure phenomenon of innovation we need a case where—preferably over a long period of time—everything that happens can be described in a uniform way within a single narrowly defined framework.<span id=\"more-67595\"></span></p>\n<p>Well, some time ago I realized that, actually, yes, there is such a case—and I’ve even personally been following it for about half a century. It’s the effort to build “engineering” structures within the <a href=\"https://www.wolframscience.com/nks/notes-6-8--structures-in-the-game-of-life/\">Game of Life cellular automaton</a>. They might serve as clocks, wires, logic gates, or things that generate digits of π. But the point is that they’re all just patterns of bits. So when we talk about innovation in this case, we’re talking about the rather pure question of how patterns of bits get invented, or discovered. </p>\n<p>As a long-time <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/\">serious researcher of the science of cellular automata</a> (and of what they generically do), I must say I’ve long been frustrated by how specific, whimsical and “non-scientific” the things people do with the Game of Life have often seemed to me to be. But what I now realize is that all that detail and all that hard work have now created what amounts to a <a href=\"https://datarepository.wolframcloud.com/resources/LifeWiki-Entity-Store/\">unique dataset</a> of engineering innovation. And my goal here is to do what one can call “metaengineering”—and to study in effect what happened in that process of engineering over the nearly six decades since the Game of Life was invented.</p>\n<p>We’ll see in rather pure form many phenomena that are at least anecdotally familiar from our overall experience of progress and innovation. Most of the time, the first step is to identify an objective: some purpose one can describe and wants to achieve. (Much more rarely, one instead observes something that happens, then realizes there’s a way one can meaningfully make use of it.) But starting from an objective, one either takes components one has, and puts human effort into arranging them to “invent” something that will achieve the objective—or in effect (usually at least somewhat systematically, and automatically) one searches to try to “discover” new ways to achieve the objective. </p>\n<p>As we explore what’s been done with the Game of Life we’ll see occasional sudden advances—together with much larger amounts of incremental progress. We’ll see towers of technology being built, and we’ll see old, rather simple technology being used to achieve new objectives. But most of all, we’ll see an interplay between what gets discovered by searching possibilities—and what gets invented by explicit human effort. </p>\n<p>The <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> implies that there is, in a sense, infinite richness to what a computational system like the Game of Life can ultimately do—and it’s the role of science to explore this richness in all its breadth. But when it comes to engineering and technology the crucial question is what we choose to make the system do—and what paths we follow to get there. Inevitably, some of this is determined by the underlying computational structure of the system. But much of it is a reflection of how we, as humans, do things, and the patterns of choices we make. And that’s what we’ll be able to study—at quite large scale—by looking at the nearly six decades of work on the Game of Life.</p>\n<p>How similar are the results of such “purposeful engineering” to the results of “blind” adaptive evolution of the kind that occurs in biology? I <a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/\">recently explored adaptive evolution</a> (as it happens, using <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">cellular automata as a model</a>) and saw that it can routinely deliver what seem like “sequences of new ideas”. But now in the example of the Game of Life we have what we can explicitly identify as “sequences of new ideas”. And so we’re in a position to compare the results of human effort (aided, in many cases, by systematic search) with what we can “automatically” do by the algorithmic process of adaptive evolution. </p>\n<p>In the end, we can think of the set of things that we can in principle engineer as being laid out in a kind of “metaengineering space”, much as we can think of mathematical theorems we can prove as being <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/\">laid out in metamathematical space</a>. In the mathematical case (notwithstanding <a href=\"https://writings.stephenwolfram.com/2025/01/who-can-understand-the-proof-a-window-on-formalized-mathematics/\">some of my own work</a>) the vast majority of theorems have historically been found purely by human effort. But, as we’ll see below, in Game-of-Life engineering it’s been a mixture of human effort and fairly automated exploration of metaengineering space. Though—much like in traditional mathematics—we’ve still in a sense always only pursuing objectives we’ve already conceptualized. And in this way what we’re doing is very different from what <a href=\"https://www.wolframscience.com/nksonline/toc.html\">I’ve done for so long in studying the science</a> (or, as I would now say, the <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#the-pure-basic-science-of-ruliology\">ruliology</a>) of what computational systems like <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/\">cellular automata</a> (of which the Game of Life is an example) do “in the wild”, when they’re unconstrained by objectives we’re trying to achieve with them. </p>\n<h2 id=\"the-nature-of-the-game-of-life\">The Nature of the Game of Life</h2>\n<p>Here’s a typical example of what it looks like to <a href=\"https://reference.wolfram.com/language/ref/CellularAutomaton.html\">run the Game of Life</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03242025video1UPimg1_copy.txt' data-c2c-type='text/html'> <video width=\"360\" height=\"246\" controls><source src=\"https://content.wolfram.com/sites/43/2025/03/anim2.mp4\" type=\"video/mp4\" /></video> </div>\n</p></div>\n<p>There’s a lot of complicated—and hard to understand—stuff going on here.

And indeed our main subject here is the actual development of such engineering over the past nearly six decades since the introduction of the Game of Life. </p>\n<p>What we’ll be concentrating on is essentially the “technology” of the Game of Life: how we take the “raw material” that the Game of Life provides, and make from it “meaningful engineering structures”.</p>\n<p>But what about the science of the Game of Life? What can we say about what the Game of Life “naturally does”, independent of “useful” structures we create in it? The vast majority of the effort that’s been put into the Game of Life over the past half century hasn’t been about this. But this type of fundamental question is central to what one asks in what I now <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#the-pure-basic-science-of-ruliology\">call ruliology</a>—<a href=\"https://www.wolframscience.com/nks/\">a kind of science</a> that I’ve been <a href=\"https://writings.stephenwolfram.com/category/new-kind-of-science/\">energetically pursuing</a> since the <a href=\"https://www.wolframscience.com/nks/chap-1--the-foundations-for-a-new-kind-of-science#sect-1-4--the-personal-story-of-the-science-in-this-book\">early 1980s</a>. </p>\n<p>Ruliology looks in general at classes of systems, rather then at the kind of specifics that have typically been explored in the Game of Life. And within ruliology, the Game of Life is in a sense nothing special; it’s just one of many <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-8--structures-in-class-4-systems\">“class 4” 2D cellular automaton</a> (in my numbering scheme, it’s the <a href=\"https://www.wolframscience.com/nks/p249--four-classes-of-behavior/\">2-color 9-neighbor cellular automaton with outer totalistic code 224</a>). </p>\n<p>My own investigations of cellular automata have particularly focused in 1D than 2D examples. And I think that’s been crucial to many of the scientific discoveries I’ve made. Because somehow one learns so much more by being able to see at a glance the history of a system, rather than just seeing frames in a video go by. With a class 4 2D rule like the Game of Life, one can begin to approach this by including “trails” of what’s previously happened, and we’ll often use <a href=\"https://www.wolframscience.com/nks/p249--four-classes-of-behavior/\">this kind of visualization</a> in what follows:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025natureimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025natureimg4.png' alt='' title='' width='640' height='311'> </div>\n</p></div>\n<p>We can get a more complete view of history by looking at the <a href=\"https://www.wolframscience.com/nks/p172--cellular-automata/\">whole (2+1)-dimensional “spacetime history”</a>—though then we’re confronted with 3D forms that are often somewhat difficult for our human visual system to parse:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025natureimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025natureimg5.png' alt='' title='' width='629' height='413'> </div>\n</p></div>\n<p>But taking a slice through this 3D form we get “silhouette” pictures that turn out to look remarkably similar to what I generated in large quantities starting in the early 1980s across many <a href=\"https://www.wolframscience.com/nks/p70--more-cellular-automata/\">1D cellular automata</a>: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025natureimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025natureimg6.png' alt='' title='' width='634' height='359'> </div>\n</p></div>\n<p>Such pictures—with their complex forms—highlight the <a href=\"https://www.wolframscience.com/nks/p737--computational-irreducibility/\">computational irreducibility</a> that’s close at hand even in the Game of Life. And indeed it’s the presence of such computational irreducibility that ultimately makes possible the richness of engineering that can be done in the Game of Life. But in actually doing that engineering—and in setting up structures and processes that behave in understandable and “technologically useful” ways—we need to keep the computational irreducibility “bottled up”. And in the end, we can think of the path of engineering innovation in the Game of Life as like an effort to navigate through an ocean of computational irreducibility, finding “islands of reducibility” that achieve the purposes we want. </p>\n<h2 id=\"whats-been-made-in-the-game-of-life\">What’s Been Made in the Game of Life?</h2>\n<p>Most of the structures of “engineering interest” in the Game of Life are somehow persistent.

(And, in that vein, structures in the Game of Life that remain constant are normally called “<a href=\"https://conwaylife.com/wiki/Still_life\" target=\"_blank\" rel=\"noopener\">still lifes</a>”.)</p>\n<p>Beyond structures that just remain constant, there are “<a href=\"https://conwaylife.com/wiki/Oscillator\" target=\"_blank\" rel=\"noopener\">oscillators</a>” that produce periodic patterns:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg2.png' alt='' title='' width='648' height='158'> </div>\n</p></div>\n<p>We’ll be discussing oscillators at much greater length below, but here are a few examples (where now we’re including a visualization that shows “trails”):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg3.png' alt='' title='' width='516' height='256'> </div>\n</p></div>\n<p>Next in our inventory of classes of structures come “gliders” (or in general “<a href=\"https://conwaylife.com/wiki/Spaceship\" target=\"_blank\" rel=\"noopener\">spaceships</a>”): structures that repeat periodically but move when they do so.

And so one of the early surprises (in 1970) was the discovery of a “<a href=\"https://conwaylife.com/wiki/Glider_gun\" target=\"_blank\" rel=\"noopener\">glider gun</a>” that shoots out a glider every 30 steps forever:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03252025whatEDimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/glider-gun.gif' alt='' title='' width='170' height='99'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg8.png' alt='' title='' width='560' height='287'> </div>\n</p></div>\n<p>Something that gives a sense of progress that’s been made in Game-of-Life “technology” is that a <a href=\"https://conwaylife.com/wiki/Period-15_glider_gun\" target=\"_blank\" rel=\"noopener\">“more efficient” glider gun</a>—with period 15—was discovered, but only in 2024, 54 years after the previous one:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg9.png' alt='' title='' width='572' height='279'> </div>\n</p></div>\n<p>Another kind of structure that was quickly discovered in the early history of the Game of Life is a “<a href=\"https://conwaylife.com/wiki/Puffer\" target=\"_blank\" rel=\"noopener\">puffer</a>”—a “spaceship” that “leaves debris behind” (in this case every 128 steps):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg10.png' alt='' title='' width='569' height='111'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg11.png' alt='' title='' width='589' height='339'> </div>\n</p></div>\n<p>But given these kinds of “components”, what can one build?

And—as we can see—they’re large (and complicated). But do they need to be so large? One of the lessons of the Principle of Computational Equivalence is that in the computational universe there’s almost always a way to “do just as much, but with much less”. And indeed in the Game of Life many, many discoveries along these lines have been made in the past few decades. </p>\n<p>As we’ll see, often (but not always) these discoveries built on “new devices” and “new mechanisms” that were identified in the intervening years. A long series of such “devices” and “mechanisms” involved handling “signals” associated with streams of gliders. For example, the “<a href=\"https://conwaylife.com/wiki/Glider_pusher\" target=\"_blank\" rel=\"noopener\">glider pusher</a>” (from 1993) has the somewhat subtle (but useful) effect of “pushing” a glider by one cell when it goes past:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg22_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg22.png' alt='' title='' width='617' height='195'> </div>\n</p></div>\n<p>Another example (actually already known in 1971, and based on the period-15 “<a href=\"https://conwaylife.com/wiki/Pentadecathlon\" target=\"_blank\" rel=\"noopener\">pentadecathlon</a>” oscillator) is a glider reflector: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg23_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg23.png' alt='' title='' width='587' height='164'> </div>\n</p></div>\n<p>But a feature of this glider pusher and glider reflector is that they work only when both the glider and the stationary object are in a particular phase with respect to their periods. And this makes it very tricky to build larger structures out of these that operate correctly (and in many cases it wouldn’t be possible but for the commensurability of the period 30 of the original glider gun, and the period 15 of the glider reflector). </p>\n<p>Could glider pushing and glider reflection be done more robustly? The answer turns out to be yes. Though it wasn’t until 2020 that the “<a href=\"https://conwaylife.com/wiki/Bandersnatch\" target=\"_blank\" rel=\"noopener\">bandersnatch</a>” was created—a completely static structure that “pushes” gliders independent of their phase:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg24_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg24.png' alt='' title='' width='581' height='281'> </div>\n</p></div>\n<p>Meanwhile, in 2013 the “<a href=\"https://conwaylife.com/wiki/Snark\" target=\"_blank\" rel=\"noopener\">snark</a>” had been created—which served as a phase-independent glider reflector:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg25_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg25.png' alt='' title='' width='552' height='242'> </div>\n</p></div>\n<p>One theme—<a href=\"https://writings.stephenwolfram.com/2025/03/what-can-we-learn-about-engineering-and-innovation-from-half-a-century-of-the-game-of-life-cellular-automaton/#building-from-history\">to which we’ll return later</a>—is that after certain functionality was first built in the Game of Life, there followed many “optimizations”, achieving that functionality more robustly, with smaller patterns, etc. An important methodology has revolved around so-called “<a href=\"https://conwaylife.com/wiki/Hassle\" target=\"_blank\" rel=\"noopener\">hasslers</a>”, which in effect allow one to “mine” small pieces of computational irreducibility, by providing “harnesses” that “rein in” behavior, typically returning patterns to their original states after they’ve done what one wants them to do. </p>\n<p>So, for example, here’s a <a href=\"https://conwaylife.com/wiki/R-pentomino_hasslers#p80\" target=\"_blank\" rel=\"noopener\">hassler</a> (found, as it happens just on February 8, 2025!) that “harnesses” the first pattern we looked at above (that didn’t stabilize for 1103 steps) into an oscillator with period 80:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg26_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025whatimg26.png' alt='' title='' width='551' height='279'> </div>\n</p></div>\n<p>And based on this (indeed, later that same day) the <a href=\"https://conwaylife.com/forums/viewtopic.php?p=203442#p203442\" target=\"_blank\" rel=\"noopener\">most-compact-ever “spaceship gun”</a> was constructed from this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03182025whatMarkimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03182025whatMarkimg2.png' alt='' title='' width='608' height='201'> </div>\n</p></div>\n<h2 id=\"the-arc-of-progress\">The Arc of Progress</h2>\n<p>We’ve talked about some of what it’s been possible to build in the Game of Life over the years. Now I want to talk about how that happened, or, in other words, the “arc of progress” in the Game of Life. And as a first indication of this, we can plot the number of new Life structures that have been identified each year (or, more specifically, the number of structures deemed significant enough to name, and to record in the <a href=\"https://conwaylife.com/wiki/\" target=\"_blank\" rel=\"noopener\">LifeWiki database</a> or its predecessors): </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg1.png' alt='' title='' width='359' height='168'> </div>\n</p></div>\n<p>There’s an immediate impression of several waves of activity. And we can break this down into activity around various common categories of structures:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg2.png' alt='' title='' width='647' height='161'> </div>\n</p></div>\n<p>For oscillators we see fairly continuous activity for five decades, but with rapid acceleration recently. For “spaceships” and “guns” we see a long dry spell from the early 1970s to the 1990s, followed by fairly consistent activity since. And for <a href=\"https://conwaylife.com/wiki/Conduit\" target=\"_blank\" rel=\"noopener\">conduits</a> and <a href=\"https://conwaylife.com/wiki/Reflector\" target=\"_blank\" rel=\"noopener\">reflectors</a> we see almost nothing until sudden peaks of activity, in the mid-1990s and mid-2010s respectively. </p>\n<p>But what was actually done to find all these structures? There have basically been two methods: construction and search. Construction is a story of “explicit engineering”—and of using human thought to build up what one wants. Search, on the other hand, is a story of automation—and of taking algorithmically generated (usually large) collections of possible patterns, and testing them to find ones that do what one wants. Particularly in more recent times it’s also become common to interleave these methods, for example using construction to build a framework, and then using search to find specific patterns that implement some feature of that framework.</p>\n<p>When one uses construction, it’s like “inventing” a structure, and when one uses search, it’s like “discovering” it. So how much of each is being done in practice? Text mining descriptions of <a href=\"https://conwaylife.com/wiki/LifeWiki:News_archive\" target=\"_blank\" rel=\"noopener\">recently recorded structures</a> the result is as follows—suggesting that, at least in recent times, search (i.e. “discovery”) has become the dominant methodology for finding new structures:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg3A_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg3.png' alt='' title='' width='464' height='152'> </div>\n</p></div>\n<p>When the Game of Life was being invented, it wasn’t long before it was being run on computers—and people were trying to classify the things it could do. Still lifes and simple oscillators showed up immediately. And then—evolving from the <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg4.png' width='13' height='13'/> (“<a href=\"https://conwaylife.com/wiki/R-pentomino\" target=\"_blank\" rel=\"noopener\">R pentomino</a>”) initial condition that we used at the beginning here—after 69 steps something unexpected showed up. In between complicated behavior that was hard to describe was a simple free-standing structure that just systematically moved—a “glider”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg5.png' alt='' title='' width='628' height='95'> </div>\n</p></div>\n<p>Some other moving structures (dubbed “spaceships”) were also observed. But the question arose: could there be a structure that would somehow systematically grow forever? To find it involved a mixture of “discovery” and “invention”. In running from the <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg6.png' width='13' height='13'/> (“R pentomino”) initial condition lots of things happen. But at step 785 it was noticed that there appeared the following structure:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg7.png' alt='' title='' width='597' height='116'> </div>\n</p></div>\n<p>For a while this structure (dubbed the “<a href=\"https://conwaylife.com/wiki/Queen_bee\" target=\"_blank\" rel=\"noopener\">queen bee</a>”) behaves in a fairly orderly way—producing two stable “beehive” structures (visible here as vertical columns). But then it “decays” into more complicated behavior:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg8.png' alt='' title='' width='159' height='238'> </div>\n</p></div>\n<p>But could this “discovered” behavior be “stabilized”? The answer was that, yes, if a “queen bee” was combined with two “<a href=\"https://conwaylife.com/wiki/Block\" target=\"_blank\" rel=\"noopener\">blocks</a>” it would just repeatedly “<a href=\"https://conwaylife.com/wiki/Queen_bee_shuttle\" target=\"_blank\" rel=\"noopener\">shuttle</a>” back and forth:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg9.png' alt='' title='' width='237' height='126'> </div>\n</p></div>\n<p>What about two “queen bees”? Now whenever these collided there was a side effect: a glider was generated—with the result that the whole structure became a <a href=\"https://conwaylife.com/wiki/Gosper_glider_gun\" target=\"_blank\" rel=\"noopener\">glider gun</a> repeatedly producing gliders forever:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg10.png' alt='' title='' width='140' height='189'> </div>\n</p></div>\n<p>The glider gun was the first major example of a structure in the Game of Life that was found—at least in part—by construction. And within a year of it being found in November 1970, <a href=\"https://conwaylife.com/wiki/New_gun_1\" target=\"_blank\" rel=\"noopener\">two more guns</a>—with very similar methods of operation—had been found: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg11.png' alt='' title='' width='331' height='193'> </div>\n</p></div>\n<p>But then the well ran dry—and no further gun was found until 1990. Pretty much the same thing happened with spaceships: four were found in 1970, but no more were found until 1989. As we’ll discuss later, it was in a sense a quintessential story of computational irreducibility: there was no way to predict (or “construct”) what spaceships would exist; one just had to do the computation (i.e. search) to find out. </p>\n<p>It was, however, easier to have incremental success with oscillators—and (as we’ll see) pretty much every year an oscillator with some new period was found, essentially always by search. Some periods were “long holdouts” (for example the first <a href=\"https://conwaylife.com/wiki/Cribbage\" target=\"_blank\" rel=\"noopener\">period-19 oscillator</a> was found only in 2023), once again reflecting the effects of computational irreducibility.</p>\n<p>Glider guns provided a source of “<a href=\"https://conwaylife.com/wiki/Conduit\" target=\"_blank\" rel=\"noopener\">signals</a>” for Life engineering. But what could one do with these signals? An important idea—that first showed up in the “<a href=\"https://conwaylife.com/wiki/Breeder_1\" target=\"_blank\" rel=\"noopener\">breeder</a>” in 1971—was “<a href=\"https://conwaylife.com/wiki/Glider_synthesis\" target=\"_blank\" rel=\"noopener\">glider synthesis</a>”: the concept that combinations of gliders could produce other structures. So, for example, it was found that three carefully-arranged gliders could generate a period-15 (“<a href=\"https://conwaylife.com/wiki/Pentadecathlon\" target=\"_blank\" rel=\"noopener\">pentadecathlon</a>”) oscillator: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03132025arcimg12.png' alt='' title='' width='650' height='61'> </div>\n</p></div>\n<p>It was also soon found that <a href=\"https://conwaylife.com/wiki/Gosper_glider_gun\" target=\"_blank\" rel=\"noopener\">8 gliders</a> could make the original glider gun (the breeder made glider guns by a slightly more ornate method). And eventually there developed the conjecture that any structure that could be synthesized from gliders would need at most 15 gliders, carefully arranged at positions whose values effectively encoded the object to be constructed. </p>\n<p>By the end of the 1970s a group of committed Life enthusiasts remained, but there was something of a feeling that “the low-hanging fruit had been picked”, and it wasn’t clear where to go next. But after a somewhat slow decade, work on the Game of Life picked up substantially towards the end of the 1980s. Perhaps <a href=\"https://www.stephenwolfram.com/publications/academic/cellular-automata/\">my own work on cellular automata</a> (and particularly the identification of <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-8--structures-in-class-4-systems\">class 4 cellular automata</a>, of which the Game of Life is a 2D example) had something to do with. And no doubt it also helped that the fairly widespread availability of faster (“workstation class”) computers now made it possible for more people to do large-scale systematic searches. In addition, when the web arrived in the early 1990s it let people much more readily share results—and had the effect of greatly expanding and organizing the community of Life enthusiasts. </p>\n<p>In the 1990s—along with more powerful searches that found new spaceships and guns—there was a burst of activity in constructing elaborate “machines” out of existing known structures. The idea was to start from a known type of “machine” (say a <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs#sect-3-4--turing-machines\">Turing machine</a>), then to construct a Life implementation of it. The constructions were made particularly ornate by the need to make the phases of gliders, guns, etc. appropriately correspond. Needless to say, any Life configuration can be thought of as doing some computation. But the “machines” that were constructed were ones whose “purpose” and “functionality” was already well established in general computation, independent of the Game of Life. </p>\n<p>If the 1990s saw a push towards “construction” in the Game of Life, the first decade of the 2000s saw a great expansion of search. Increasingly powerful cloud and distributed computing allowed “<a href=\"https://conwaylife.com/wiki/Category:Censuses\" target=\"_blank\" rel=\"noopener\">censuses</a>” to be created of structures emerging from billions, then trillions of initial conditions. Mostly what was emphasized was finding new instances of existing categories of objects, like oscillators and spaceships. There were particular challenges, like (as we’ll discuss below) finding oscillators of any period (<a href=\"https://conwaylife.com/wiki/Omniperiodic\" target=\"_blank\" rel=\"noopener\">finally completely solved in 2023</a>), or finding spaceships with different patterns of motion. Searches did yield what in censuses were usually called “<a href=\"https://catagolue.hatsya.com/census/b3s23/C1\" target=\"_blank\" rel=\"noopener\">objects with unusual growth</a>”, but mostly these were not viewed as being of “engineering utility”, and so were not extensively studied (even though from the point of the “science of the Game of Life” they are, for example, perhaps the <a href=\"https://www.wolframscience.com/nks/p740--computational-irreducibility/\">most revealing examples of computational irreducibility</a>).</p>\n<p>As had happened throughout the history of the Game of Life, some of the most notable new structures were created (sometimes over a long period of time) by a mixture of construction and search.

At the outset, it’s far from obvious that such a strategy would be viable. But the fact that it is seems to be similar to the story of why both <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">biological evolution</a> and <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">machine learning</a> are viable—which, as I’ve recently discussed, can be viewed as yet another consequence of the phenomenon of computational irreducibility.</p>\n<p>One thing that’s happened many times in the history of the Game of Life is that at some point some category of structure—like a conduit—is identified, and named. But then it’s realized that actually there was something that could be seen as an instance of the same category of structure found much earlier, though without the clarity of the later instance, its significance wasn’t recognized.

The activity brought in people from many different backgrounds. And particularly in earlier years, they often operated quite independently, and with very different methods (some not even using a computer).

The period-2 “blinker” was very obvious—showing up in evolution from almost any random initial condition. Some other oscillators were also easily found by looking at the evolution of particular, simple initial conditions. For example, a line of 10 black cells after 3 steps gives the period-15 “<a href=\"https://conwaylife.com/wiki/Pentadecathlon\" target=\"_blank\" rel=\"noopener\">pentadecathlon</a>”.

But there were still holdouts, like period 19 and for example pretty much all periods between 61 and 70 (except, as it happens, 66). At the time, though, all sorts of complicated constructions—say of prime generators—were nevertheless being done. And in 1996 it was figured out that one could in effect always “build a machine” (using only structures that had already been found two decades earlier) that would serve as an <a href=\"https://conwaylife.com/wiki/Herschel_circuit\" target=\"_blank\" rel=\"noopener\">oscillator of any (sufficiently large) period</a> (here 67)—effectively by “sending a signal around a loop of appropriate size”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03142025exampleimg17_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03142025exampleimg17.png' alt='' title='' width='462' height='185'> </div>\n</p></div>\n<p>But by the 2010s, with large numbers of fast computers becoming available, there was again an emphasis on pure random search. A handful of <a href=\"https://conwaylife.com/wiki/Tutorials/Software\" target=\"_blank\" rel=\"noopener\">highly efficient programs were developed</a>, that could be run on anyone’s machine. In a typical case, a search might consist of starting, say, from a trillion randomly chosen initial conditions (or “<a href=\"https://conwaylife.com/wiki/Soup\" target=\"_blank\" rel=\"noopener\">soups</a>”), identifying new structures that emerge, then seeing whether these act, for example, as oscillators. Typically any new discovery was immediately reported in <a href=\"https://conwaylife.com/forums/\" target=\"_blank\" rel=\"noopener\">online forums</a>—leading to variations of it being tried, and new follow-on results often being reported within hours or days.</p>\n<p>Many of the random searches started just from 16×16 regions of randomly chosen cells (or larger regions with symmetries imposed). And in a typical manifestation of computational irreducibility, many surprisingly small and “random-looking” (at least up to symmetries) results were found. So, for example, here’s the sequence of recorded <a href=\"https://conwaylife.com/wiki/Category:Oscillators_with_period_16\" target=\"_blank\" rel=\"noopener\">period-16 oscillators</a> with smaller-than-before cases highlighted:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03142025exampleimg18_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03142025exampleimg18.png' alt='' title='' width='473' height='216'> </div>\n</p></div>\n<p>Up through the 1990s results were typically found by a mixture of construction and small-scale search. But in 2016, results from <a href=\"https://conwaylife.com/wiki/Apgsearch\" target=\"_blank\" rel=\"noopen\">large-scale random searches</a> (sometimes symmetrical, sometimes not) started to appear. </p>\n<p>The contrast between construction and search could be dramatic, like here for <a href=\"https://conwaylife.com/wiki/Category:Oscillators_with_period_57\" target=\"_blank\" rel=\"noopener\">period 57</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03142025exampleimg19_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03142025exampleimg19.png' alt='' title='' width='297' height='172'> </div>\n</p></div>\n<p>One might wonder whether there could actually be a systematic, purely algorithmic way to find, say, possible oscillators of a given period. And indeed for one-dimensional cellular automata (<a href=\"https://content.wolfram.com/sw-publications/2020/07/computation-theory-cellular-automata.pdf\" target=\"_blank\" rel=\"noopener\">as I noted in 1984</a>), it turns out <a href=\"https://www.wolframscience.com/nks/p285--structures-in-class-4-systems/\">that there is.</a> Say one considers blocks of cells of width <em>w</em>. Which block can follow which other is determined by a de Bruijn graph, or equivalently, a finite state machine. If one is going to have a pattern with period <em>p</em>, all blocks that appear in it must also be periodic with period <em>p</em>. But such blocks just form a subgraph of the overall de Bruijn graph, or equivalently, form another, smaller, finite state machine. And then all patterns with period <em>p</em> must <a href=\"https://www.wolframscience.com/nks/p268--special-initial-conditions/\">correspond to paths through this subgraph</a>. But how long are the blocks one has to consider?</p>\n<p>In 1D cellular automata, it turns out that there’s <a href=\"https://content.wolfram.com/sw-publications/2020/07/computation-theory-cellular-automata.pdf\">an upper bound of 2<sup>2<em>p</em></sup></a>. But for 2D cellular automata—like the Game of Life—there is in general no such upper bound, a fact related to the <a href=\"https://www.wolframscience.com/nks/notes-12-8--undecidability-in-tiling-problems/\">undecidability of the 2D tiling problem</a>. And the result is that there’s no complete, systematic algorithm to find oscillators in a general 2D cellular automaton, or presumably in the Game of Life. </p>\n<p>But—as was actually already realized in the mid-1990s—it’s still possible to use algorithmic methods to <a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/FindMinimalTilings/\">“fill in” pieces of patterns</a>. The idea is to define part of a pattern of a given period, then use this as a constraint on filling in the rest of it, finding “solutions” that satisfy the constraint using <a href=\"https://reference.wolfram.com/language/ref/SatisfiabilityInstances.html\">SAT-solving techniques</a>. In practice, this approach has more often been used for spaceships than for oscillators (not least because it’s only practical for small periods). But one feature of it is that it can generate fairly large patterns with a given period.</p>\n<p>Yet another method that’s been tried has been to generate oscillators by colliding gliders in many possible ways. But while this is definitely useful if one’s interested in what can be made using gliders, it doesn’t seem to have, for example, allowed people to find much in the way of interesting new oscillators. </p>\n<h2 id=\"modularity\">Modularity</h2>\n<p>In traditional engineering a key strategy is modularity. Rather than trying to build something “all in one go”, the idea is to build a collection of independent subsystems, from which the whole system can then be assembled. But how does this work in the Game of Life? We might imagine that to identify the modular parts of a system, we’d have to know the “process” by which the system was put together, and the “intent” involved. But because in the Game of Life we’re ultimately just dealing with pure patterns of bits we can in effect just as well “come in at the end” and algorithmically figure out what pieces are operating as separate, modular parts.</p>\n<p>So how can we do this? Basically what we want to find out is which parts of a pattern “operate independently” at a given step, in the sense that these parts don’t have any overlap in the cells they affect.

Parts that appear “horizontally separated” (or, more precisely, in antichains, or in <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">physics terminology</a>, spacelike separated) can be generated independently and in parallel. But parts that follow each other in the partial order need to be generated in that order (i.e. in physics terms, they are timelike separated).</p>\n<p>As another example, let’s look at graphs for the various oscillators of period 16 that we showed above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03182025modularityimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03182025modularityimg6.png' alt='' title='' width='576' height='330'> </div>\n</p></div>\n<p>What we see is that the early period-16 oscillators were quite modular, and had many parts that in effect operated independently. But the later, smaller ones were not so modular. And indeed the last one shown here had no parts that could operate independently; the whole pattern had to be taken together at each step.</p>\n<p>And indeed, what we’ll often see is that the more optimized a structure is, the less modular it tends to be. If we’re going to construct something “by hand” we usually need to assemble it in parts, because that’s what allows us to “understand what we’re doing”. But if, for example, we just find a structure in a search, there’s no reason for it to be “understandable”, and there’s no reason for it to be particularly modular. </p>\n<p>Different steps in a given oscillator can involve different numbers of modular parts. But as a simple way to assess the “modularity” of an oscillator, we can just ask for the average number of parts over the course of one period. So as an example, here are the results for period-30 oscillators:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03182025modularityimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03182025modularityimg7.png' alt='' title='' width='678' height='265'> </div>\n</p></div>\n<p><a href=\"https://writings.stephenwolfram.com/2025/03/what-can-we-learn-about-engineering-and-innovation-from-half-a-century-of-the-game-of-life-cellular-automaton/#invented-or-discovered-made-for-a-purpose-at-all\">Later</a>, we’ll discuss how we can use the level of modularity to assess whether a pattern is likely to have been found by a search or by construction.

But what about the overall “flow of engineering progress”? And, in particular, when something new is found, how much does it build on what has been found before? In real-world engineering, things like patent citations potentially give one an indication of this.

It’s also notable that (for no particularly obvious reason) the frequency of the <em>n</em><sup>th</sup> <a href=\"https://www.wolframscience.com/nksonline/page-1014b/\">most common structure is roughly 1/<em>n</a></em>.</p>\n<p>So when were the various structures that appear here first found? As this picture shows, most—but not all—were found very early in the history of the Game of Life:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03242025buildingUPBimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03242025buildingUPBimg6.png' alt='' title='' width='643' height='271'> </div>\n</p></div>\n<p>In other words, most of the parts used in structures from any time in the history of the Game of Life come from very early in its history.

Because here we’re always treating each modular part of each pattern as a separate entity, so that we consider any given pattern to “depend” only on base modular parts. But “really” it could depend on another whole structure, itself built of many modular parts. And in what we’re doing here, we’re not tracking that hierarchy of dependencies. Were we to do so, we would likely be able to see more complex “technology stacks” in the Game of Life. But instead we’re always “going down to the primitives”. (If we were dealing with electronics it’d be like asking “What are the transistors and capacitors that are being used?”, rather than “What is the caching architecture, or how is the floating point unit set up?”)</p>\n<p>OK, but in terms of “base modular parts” a simple question to ask is how many get used in each pattern.

But now we also see that there have been an increasing number of patterns that use many modular parts—typically reflecting a higher degree of “construction” (rather than search) going on.</p>\n<p>By the way, for comparison, these plots show the total areas and the numbers of (black) cells in patterns found in each year; both show increases early on, but more or less level off by the 1990s:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03242025buildingUPBimg15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03242025buildingUPBimg15.png' alt='' title='' width='640' height='119'> </div>\n</p></div>\n<p>But, OK, if we look across all patterns in the database, how many parts do they end up using?

But a different possible objective is to find patterns that have some feature we can recognize, whether with obvious immediate “utility” or not. And as one example of this we can think about finding so-called “die hard” patterns that live as long as possible before dying out. </p>\n<p>The phenomenon of computational irreducibility tells us that even given a particular pattern we can’t in general “know in advance” how long it’s going to take to die out (or if it ultimately dies out at all). So it’s inevitable that the problem of finding ultimate die-hard patterns can be unboundedly difficult, just like <a href=\"https://writings.stephenwolfram.com/2021/03/after-100-years-can-we-finally-crack-posts-problem-of-tag-a-story-of-computational-irreducibility-and-more/\">analogous problems for other computational systems</a> (such as finding so-called <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#computation-theoretic-perspectives-and-busy-beavers\">“busy beavers” in Turing machines</a>). </p>\n<p>But in practice one can use both search and construction techniques to find patterns that at least live a long time (even if not the very longest possible time). And as an example, here’s a <a href=\"https://conwaylife.com/wiki/Die_hard\" target=\"_blank\" rel=\"noopener\">very simple pattern</a> (found by search) that lives for 132 steps before dying out (the “puff” at the end on the left is a reflection of how we’re showing “trails”; all the actual cells are zero at that point): </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03172025lifetimeimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03172025lifetimeimg1.png' alt='' title='' width='449' height='344'> </div>\n</p></div>\n<p>Searching nearly 10<sup>16</sup> <a href=\" https://conwaylife.com/wiki/Die_hard \" target=\"_blank\" rel=\"noopener\">randomly chosen 16×16 patterns</a> (out of a total of ≈ 10<sup>77</sup> possible such patterns), the<a href=\"https://conwaylife.com/forums/viewtopic.php?&p=172182#p172182 \" target=\"_blank\" rel=\"noopener\"> longest lifetime found is 1413 steps</a>—achieved with a rather random-looking initial pattern:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03172025lifetimeimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03172025lifetimeimg4.png' alt='' title='' width='510' height='299'> </div>\n</p></div>\n<p>But is this the best one can do?

Both involve the concept of trying out possibilities and building on ones that work. But technology development has always ultimately been driven by human effort, whereas biological evolution is, in effect, a “blind” process, based on the natural selection of random mutations. So what happens if we try to apply <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">something like biological evolution</a> to the Game of Life? As an example, let’s look at adaptive evolution that’s trying to maximize finite lifetime based on making a sequence of random point mutations within an initially random 16×16 pattern. Most of those mutations don’t give patterns with larger (finite) lifetimes, but occasionally there’s a “breakthrough” and the lifetime achieved so far jumps up:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03182025comparisonimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03182025comparisonimg1.png' alt='' title='' width='391' height='172'> </div>\n</p></div>\n<p>The actual behaviors corresponding to the breakthroughs in this case are:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03182025comparisonimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03182025comparisonimg2.png' alt='' title='' width='342' height='329'> </div>\n</p></div>\n<p>And here are some other outcomes from adaptive evolution:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03182025comparisonimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03182025comparisonimg3.png' alt='' title='' width='638' height='238'> </div>\n</p></div>\n<p>In almost all cases, a limited number of steps of adaptive evolution do succeed in generating patterns with fairly long finite lifetimes. But the behavior we see typically shows no “readily understandable mechanisms”—and no obviously separable modular parts. And instead—just like in my recent studies of both <a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/\">biological evolution</a> and <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">machine learning</a>—what we get are basically “lumps of irreducible computation” that “just happen” to show what we’re looking for (here, long lifetime). </p>\n<h2 id=\"invented-or-discovered-made-for-a-purpose-at-all\">Invented or Discovered? Made for a Purpose at All?</h2>\n<p>Let’s say we’re presented with an array of cells that’s an initial condition for the Game of Life. Can we tell “where it came from”? Is it “just arbitrary” (or “random”)? Or was it “set up for a purpose”? And if it was “set up for a purpose”, was it “invented” (and “constructed”) for that purpose, or was it just “discovered” (say by a search) to fulfill that purpose?</p>\n<p>Whether one’s dealing with archaeology, evolutionary biology, forensic science, the identification of alien intelligence or, for that matter, theology, the question of whether something “<a href=\"https://www.wolframscience.com/nks/p830--intelligence-in-the-universe/\">was set up for a purpose</a>” is a <a href=\"https://writings.stephenwolfram.com/2018/01/showing-off-to-the-universe-beacons-for-the-afterlife-of-our-civilization/\">philosophically fraught one</a>. Any behavior one sees one can potentially explain either in terms of the mechanism that produces it, or in terms of what it “achieves”. Things get a little clearer if we have a particular language for describing both mechanisms and purposes. Then we can ask questions like: “Is the behavior we care about more succinctly described in terms of its mechanism or its purpose?” So, for example, “It behaves as a period-15 glider gun” might be an adequate purpose-oriented description, that’s much shorter than a mechanism-oriented description in terms of arrangements of cells. </p>\n<p>But what is the appropriate “lexicon of purposes” for the Game of Life? In effect, that’s a core question for Game-of-Life engineering. Because what engineering—and technology in general—is ultimately about is taking whatever raw material is available (whether from the physical world, or from the Game of Life) and somehow fashioning it into something that aligns with human purposes. But then we’re back to what counts as a valid human purpose. How deeply does the purpose have to connect in to everything we do? Is it, for example, enough for something to “look nice”, or is that not “utilitarian enough”? There <a href=\"https://writings.stephenwolfram.com/2018/01/showing-off-to-the-universe-beacons-for-the-afterlife-of-our-civilization/\">aren’t absolute answers to these questions</a>. And indeed the answers can change over time, as new uses for things are discovered (or invented).</p>\n<p>But for the Game of Life we can start with some of the “purposes” we’ve discussed here—like “be an oscillator of a certain period”, “reflect gliders”, “generate the primes” or even just “die after as long as possible”. Let’s say we just start enumerating possible initial patterns, either randomly, or exhaustively. How often will we come across patterns that “achieve one of these purposes”? And will it “only achieve that purpose” or will it also “do extra stuff” that “seems irrelevant”? </p>\n<p>As an example, consider enumerating all possible 3×3 patterns of cells. There are altogether <nobr>2<sup>9</sup> = 512</nobr> such patterns, or just 102 after reducing by symmetries. Of these, 79 evolve to purely static patterns, while 17 evolve to patterns of period 2.

And we can view this as an immediate signal for “how human” each pattern is. In a sense it’s a reflection of the computational boundedness of our minds. When there are factored modular parts that interact fairly rarely and each behave in a fairly simple way, it’s realistic for us to “get our minds around” what’s going on. But when there’s just an “irreducible blob of activity” we’d have to compute too much and keep too much in mind at once for us to be able to really “understand what’s going on” and for example produce a human-level narrative explanation of it. </p>\n<p>If we find a pattern by search, however, we don’t really have to “understand it”; it’s just something we computationally “discover out there in the computational universe” that “happens” to do what we want. And, indeed, as in the example here, it often does what it does in a quite minimal (if incomprehensible) way. Something that’s found by human effort is much less likely to be minimal; in effect it’s at least somewhat “optimized for comprehensibility” rather than for minimality or ease of being found by search. And indeed it will often be far too big (e.g. in terms of number of cells) for any pure exhaustive or random search to plausibly find it—even though the “human-level narrative” for it might be quite short. </p>\n<p>Here are the causal graphs for all the period-9 oscillators from above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/04/sw04232025inventedQimg16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/04/sw04232025inventedXimg16.png' alt='' title='' width='439' height='466'> </div>\n</p></div>\n<p>Some we can see can readily be broken down into multiple rarely interacting distinct components; others can’t be decomposed in this kind of way. And in a first approximation, the “decomposable” ones seem to be precisely those that were somehow “constructed by human effort”, while the non-decomposable ones seem to be those that were “discovered by searches”.</p>\n<p>Typically, the way the “constructions” are done is to start with some collection of known parts, then, by trial and error (sometimes computer assisted) see how these can be fit together to get something that does what one wants. Searches, on the other hand, typically operate on “raw” configurations of cells, blindly going through a large number of possible configurations, at every stage automatically testing whether one’s got something that does what one wants. </p>\n<p>And in the end these different strategies reveal themselves in the character of the final patterns they produce, and in the causal graphs that represent these patterns and their behavior.</p>\n<h2 id=\"principles-of-engineering-strategy-from-the-game-of-life\">Principles of Engineering Strategy from the Game of Life</h2>\n<p>In engineering as it’s traditionally been practiced, the main emphasis tends to be on figuring out plans, and then constructing things based on those plans. Typically one starts from components one has, then tries to figure out how to combine them to incrementally build up what one wants. </p>\n<p>And, as we’ve discussed, this is also a way of developing technology in the Game of Life. But as we’ve discussed at length, it’s not the only way. Another way is just to search for whole pieces of technology one wants. </p>\n<p>Traditional intuition might make one assume this would be hopeless. But the repeated lesson of <a href=\"https://www.wolframscience.com/nks/\">my discoveries about simple programs</a>—as well as what’s been done with the Game of Life—is that actually it’s often not hopeless at all, and instead it’s very powerful. </p>\n<p>Yes, what you get is not likely to be readily “understandable”. But it is likely to be minimal and potentially quite optimal for whatever it is that it does. I’ve often talked of this approach as “<a href=\"https://writings.stephenwolfram.com/2022/06/alien-intelligence-and-the-concept-of-technology/\">mining from the computational universe</a>”. And over the course of many years I’ve had success with it in all sorts of disparate areas. And now, here, we’ve see in the Game of Life a particularly clean example where search is used alongside construction in developing technology. </p>\n<p>It’s a feature of things produced by construction that they are “born understandable”. In effect, they are computationally reducible enough that we can “fit them in our finite minds” and “understand them”. But things found by search don’t have this feature. And most of the time the behavior they’ll show will be full of computational irreducibility. </p>\n<p>In both <a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/\">biological evolution</a> and <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">machine learning</a> my recent investigations suggest that most of what we’re seeing are “lumps of irreducible computation” found at random that just “happen to achieve the necessary objectives”. This hasn’t been something familiar in traditional engineering, but it’s something tremendously powerful. And from the examples we’ve seen here in the Game of Life it’s clear that it can often achieve things that seem completely inaccessible by traditional methods based on explicit construction. </p>\n<p>At first we might assume that irreducible computation is too unruly and unpredictable to be useful in achieving “understandable objectives”. But if we find just the right piece of irreducible computation then it’ll achieve the objective we want, often in a very minimal way. And the point is that the computational universe is in a sense big enough that we’ll usually be able to find that “right piece of irreducible computation”. </p>\n<p>One thing we see in Game-of-Life engineering is something that’s in a sense a compromise between irreducible computation and predictable construction. The basic idea is to take something that’s computationally irreducible, and to “put it in a cage” that constrains it to do what one wants. The computational irreducibility is in a sense the “spark” in the system; the cage provides the control we need to harness that spark in a way that meets our objectives.</p>\n<p>Let’s look at some examples. As our “spark” we’ll use the R pentomino <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03172025principlesimg1.png' alt='' title='' width='13' height='13'/> that we <a href=\"https://writings.stephenwolfram.com/2025/03/what-can-we-learn-about-engineering-and-innovation-from-half-a-century-of-the-game-of-life-cellular-automaton/#the-nature-of-the-game-of-life\">discussed at the very beginning</a>. On its own, this generates all sorts of complex behavior—that for the most part doesn’t align with typical objectives we might define (though as a “side show” it does happen to generate gliders). But the idea is to put constraints on the R pentomino to make it “useful”. </p>\n<p>Here’s a case where we’ve tried to “build a road” for the R pentomino to go down:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03172025principlesimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03172025principlesimg2.png' alt='' title='' width='661' height='104'> </div>\n</p></div>\n<p>And looking at this every 18 steps we see that, at least for a while, the R pentomino has indeed moved down the road. But it’s also generated something of an “explosion”, and eventually this explosion catches up, and the R pentomino is destroyed. </p>\n<p>So can we maintain enough control to let the R pentomino survive? The answer is yes. And here, for example, is a period-12 oscillator, “powered” by an R pentomino at its center:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03172025principlesimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03172025principlesimg3.png' alt='' title='' width='597' height='163'> </div>\n</p></div>\n<p>Without the R pentomino, the structure we’ve set up cycles with period 6:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03172025principlesimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03172025principlesimg4.png' alt='' title='' width='597' height='78'> </div>\n</p></div>\n<p>And when we insert the R pentomino this structure “keeps it under control”—so that the only effect it ultimately has is to double the period, t0 12. </p>\n<p>Here’s a more dramatic example.

But what about more complex objectives? Of course, any pattern of cells in the Game of Life will do something. But the question is whether that something aligns with technological objectives we have. </p>\n<p>Generically, things in the Game of Life will behave in computationally irreducible ways. And it’s this very fact that gives such richness to what can be done with the Game of Life. But can the computational irreducibility be controlled—and harnessed for technological purposes? In a sense that is the core challenge of engineering in both the Game of Life, and in the real world. (It’s also rather directly the challenge we face in making use of the computational power of AI, but still adequately aligning it with human objectives.)</p>\n<p>As we look at the arc of technological development in the Game of Life we see over the course of half a century all sorts of different advances being made. But will there be an end to this? Will we eventually run out of inventions and discoveries? The underlying presence of computational irreducibility makes it clear that we will not. The only thing that might end is the set of objectives we’re trying to meet. We now know how to make oscillators of any period. And unless we insist on for example finding the smallest oscillator of a given period, we can consider the problem of finding oscillators solved, with nothing more to discover. </p>\n<p>In the real world nature and the evolution of the universe inevitably confront us with new issues, which lead to new objectives. In the Game of Life—as in any other abstract area, <a href=\"https://www.wolframscience.com/metamathematics/\">like mathematics</a>—the issue of defining new objectives is up to us. Computational irreducibility leads to infinite diversity and richness of what’s possible. The issue for us is to figure out <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/\">what direction we want to go</a>. And the story of engineering and technology in the Game of Life gives us, in effect, a simple model for the issues we confront in other areas of technology, like AI.</p>\n<h2 id=\"some-personal-backstory\">Some Personal Backstory</h2>\n<p>I’m not sure if I made the right decision back in 1981. I had come up with a very simple class of systems and was doing computer experiments on them, and was starting to get some interesting results. And when I mentioned what I was doing to a group of (then young) computer scientists they said “Oh, those things you’re studying are called cellular automata”. Well, actually, the cellular automata they were talking about were 2D systems while mine were 1D. And though that might seem like a technical difference, it has a big effect on one’s impression of what’s going on—because in 1D one can readily see “spacetime histories” that gave an immediate sense of the “whole behavior of the system”, while in 2D one basically can’t. </p>\n<p>I wondered what to call my models. I toyed with the term “polymones”—as a modernized nod to Leibniz’s monads. But in the end I decided that I should stick with a simpler connection to history, and just call my models, like their 2D analogs, “cellular automata”. In many ways I’m happy with that decision. Though one of its downsides has been a certain amount of conceptual confusion—more than anything centered around the Game of Life. </p>\n<p>People often know that the Game of Life is an example of a cellular automaton. And they also know that within the Game of Life lots of structures (like gliders and glider guns) can be set up to do particular things. Meanwhile, they hear about <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/\">my discoveries about the generation of complexity in cellular automata (like rule 30)</a>. And somehow they conflate these things—leading to all too many books etc. that show pictures of simple gliders in the Game of Life and say “Look at all this complexity!”</p>\n<p>At some level it’s a confusion between science and engineering. My efforts around cellular automata have centered on empirical science questions like “What does this cellular automaton do if you run it?” But—as I’ve discussed at length above—most of what’s been done with the Game of Life has centered instead on questions of engineering, like “What recognizable (or useful) structures can you build in the system?” It’s a different objective, with different results. And, in particular, by asking to “engineer understandable technology” one’s specifically eschewing the phenomenon of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>—and the whole story of the emergence of complexity that’s been so central to my own scientific work on cellular automata and so much else.</p>\n<p>Many times over the years, people would show me things they’d been able to build in the Game of Life—and I really wouldn’t know what to make of them. Yes, they seemed like impressive hacks. But what was the big picture? Was this just fun, or was there some broader intellectual point? Well, finally, not long ago I realized: this is not a story of science, it’s a story about the arc of engineering, or what one can call “metaengineering”. </p>\n<p>And back in 2018, in connection with the upcoming 50th anniversary of the Game of Life, I decided to see what I could figure out about this. But I wasn’t satisfied with how far I got, and other priorities interceded. So—beyond one small comment that ended up in a <a href=\"https://www.nytimes.com/2020/12/28/science/math-conway-game-of-life.html#\" target=\"_blank\" rel=\"noopener\">2020 <em>New York Times</em> article</a>—I didn’t write anything about what I’d done. And the project languished. Until now. When somehow my long-time interest in “<a href=\"https://writings.stephenwolfram.com/category/language-and-communication/\">alien engineering</a>”, combined with my <a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/\">recent results about biological evolution</a> coalesced into a feeling that it was time to finally figure out what we could learn from all that effort that’s been put into the Game of Life.</p>\n<p>In a sense this brings closure to a very long-running story for me. The first time I heard about the Game of Life was in 1973. I was an early teenager then, and I’d just gotten access to a computer. By today’s standards <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">the computer (an Elliott 903C)</a> was a primitive one: the size of a desk, programmed with paper tape, with only 24 kilobytes of memory. I was interested in using it for things like writing a <a href=\"https://writings.stephenwolfram.com/2023/02/a-50-year-quest-my-personal-journey-with-the-second-law-of-thermodynamics/#when-i-was-12-years-old\">simulator for the physics of idealized gas molecules</a>. But other kids who had access to the computer were instead more interested (much as many kids might be today) in writing games. Someone wrote a “Hunt the Wumpus” game. And someone else wrote a program for the “Game of Life”. The configurations of cells at each generation were printed out on a teleprinter. And for some reason people were particularly taken with the “Cheshire cat” configuration, in which all that was left at the end (as in Alice in Wonderland) was a “smile”. At the time, I absolutely didn’t see the point of any of this. I was interested in science, not games, and the Game of Life pretty much lost me at “Game”. </p>\n<p>For a number of years I didn’t have any further contact with the Game of Life. But then I met Bill Gosper, who I later learned had in 1970 discovered the glider gun in the Game of Life. I met Gosper first “online” (yes, even in 1978 that was a thing, at least if you used the <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">MIT-MC computer through the ARPANET</a>)—then in person in 1979. And in 1980 I visited him at Xerox PARC, where he described himself as part of the “entertainment division” and gave me strange math formulas printed on a not-yet-out-of-the-lab color laser printer</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg1.png' alt='Bill Gosper math formulas' title='Bill Gosper math formulas' width='490' height='142'/></p>\n<p>and also showed me a bitmapped display (complete with GUI) with lots of pixels dancing around that he enthusiastically explained were showing the Game of Life. Knowing what I know now, I would have been excited by what I saw. But at the time, it didn’t really register.</p>\n<p>Still, in 1981, having started my big investigation of 1D cellular automata, and having made the connection to the 2D case of the Game of Life, I started wondering whether there was something “scientifically useful” that I could glean from all the effort I knew (particularly from Gosper) had been put into Life. It didn’t help that almost none of the output of that effort had been published. And in those days before the web, personal contact was pretty much the only way to get unpublished material. One of my larger “finds” was from a friend of mine from Oxford who passed on “lab notebook pages” he’d got from someone who was enumerating outcomes from different Game-of-Life initial configurations:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg2-min.png' alt='Game-of-Life initial configurations' title='Game-of-Life initial configurations' width='614' height='539'/></p>\n<p>And from material like this, as well as my own simulations, I came up with some tentative “scientific conclusions”, which I summarized in 1982 in a paragraph in <a href=\"https://files.wolframcdn.com/pub/www.stephenwolfram.com/pdf/statistical-mechanics-cellular-automata.pdf\" target=\"_blank\" rel=\"noopener\">my first big paper about cellular automata</a>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg3-min.png' alt='Stephen Wolfram cellular automata paper' title='Stephen Wolfram cellular automata paper' width='626' height='421'/></p>\n<p>But then, at the beginning of 1983, as part of my continuing effort to do science on cellular automata, I made a discovery. Among all cellular automata there seemed to be <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-2--four-classes-of-behavior\">four basic classes of behavior</a>, with class 4 being characterized by the <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-8--structures-in-class-4-systems\">presence of localized structures</a>, sometimes just periodic, and sometimes moving:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg4.png' alt='Class 4 cellular automata behavior' title='Class 4 cellular automata behavior' width='567' height='211'/></p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03182025backstoryNEWimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03182025backstoryNEWimg1.png' alt='' title='' width='658' height='215'> </div>\n</p></div>\n<p>I immediately recognized the analogy to the Game of Life, and to oscillators and gliders there. And indeed this analogy was part of what “tipped me off” to thinking about the ubiquitous computational capabilities of cellular automata, and to the phenomenon of computational irreducibility.</p>\n<p>Meanwhile, in March 1983, I co-organized what was effectively the <a href=\"https://content.wolfram.com/sw-publications/2020/07/preface-cellular-automata.pdf\" target=\"_blank\" rel=\"noopener\">first-ever conference on cellular automata (held at Los Alamos)</a>—and one of the people I invited was Gosper. He announced his Hashlife algorithm (which was crucial to future Life research) there, and came bearing gifts: printouts for me of Life, that I annotated, and still have in my archives:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg5.png' alt='Annotated printouts' title='Annotated printouts' width='399' height='670'/></p>\n<p>I asked Gosper to do some “more scientific” experiments for me—for example starting from a region of randomness, then seeing what happened:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg6.png' alt='More Game-of-Life experiments' title='More Game-of-Life experiments' width='461' height='274'/></p>\n<p>But Gosper really wasn’t interested in what I saw as being science; he wanted to do engineering, and make constructions—like this one he gave me, showing two glider guns exchanging streams of gliders (why would one care, I wondered):</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg7.png' alt='Two glider guns' title='Two glider guns' width='250' height='286'/></p>\n<p>I’d mostly studied 1D cellular automata—where I’d discovered a lot by systematically looking at their behavior “laid out in spacetime”. But in early 1984 I resolved to also systematically check out 2D cellular automata. And mostly the resounding conclusion was that their basic behavior was very similar to 1D. Out of all the rules we studied, the Game of Life didn’t particularly stand out. But—mostly to provide a familiar comparison point—I included pictures of it in the <a href=\"https://content.wolfram.com/sw-publications/2020/07/two-dimensional-cellular-automata.pdf\" target=\"_blank\" rel=\"noopener\">paper we wrote</a>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg8.png' alt='2D cellular automata' title='2D cellular automata' width='512' height='388'/></p>\n<p>And we also went to the trouble of making a 3D “spacetime” picture of the Game of Life on a Cray supercomputer—though it was too small to show anything terribly interesting:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg9.png' alt='3D Game of Life' title='3D Game of Life' width='287' height='215'/></p>\n<p>It had been a column in <em>Scientific American</em> in 1970 that had first propelled the Game of Life to public prominence—and that had also launched the first great Life engineering challenge of finding a glider gun. And in both 1984 and 1985 a successor to that very same column <a href=\"https://www.stephenwolfram.com/media/computer-recreations/\">ran stories about my 1D cellular automata</a>. And in 1985, in collaboration with <em>Scientific American</em>, I thought it would be fun and interesting to reprise the 1970 glider gun challenge, but <a href=\"https://content.wolfram.com/sw-publications/2023/02/glider-gun-guidelines.pdf\" target=\"_blank\" rel=\"noopener\">now for 1D class 4 cellular automata</a>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg10-min.png' alt='Glider gun guidelines paper' title='Glider gun guidelines paper' width='494' height='766'/></p>\n<p>Many people participated. And my main conclusion was: yes, it seemed like one could do the same kinds of engineering in typical 1D class 4 cellular automata as one could in the Game of Life. But this was all several years before the web, and the kind of online community that has driven so much Game of Life engineering in modern times wasn’t yet able to form.</p>\n<p>Meanwhile, by the next year, I was <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">starting the development of Mathematica</a> and what’s now the <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>, and for a few years didn’t have much time to think about cellular automata. But in 1987 when Gosper got involved in making pre-release demos of Mathematica he once again excitedly told me about his discoveries in the Game of Life, and gave me pictures like:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg11.png' alt='Gliders guns using early Mathematica' title='Gliders guns using early Mathematica' width='430' height='325'/></p>\n<p>It was in 1992 that the Game of Life once again appeared in my life. I had recently embarked on what would become the <a href=\"https://writings.stephenwolfram.com/2022/05/the-making-of-a-new-kind-of-science/\">10-year project</a> of writing my book <em><a href=\"https://www.wolframscience.com/nksonline/toc.html\">A New Kind of Science</a></em>. I was working on one of the rather few “I already have this figured out” sections in the book—and I wanted to compare class 4 behavior in 1D and 2D. How was I to display the Game of Life, especially in a static book? Equipped with what’s now the Wolfram Language it was easy to <a href=\"https://www.wolframscience.com/nks/p249--four-classes-of-behavior/\">come up with visualizations</a>—looking “out” into a spacetime slice with more distant cells “in a fog”, as well as “down” into a fog of successive states:</p>\n<p><a href=\"https://www.wolframscience.com/nks/p249--four-classes-of-behavior/\" ><img src='https://content.wolfram.com/sites/43/2025/03/NKS-page.png' alt='Game of Life in A New Kind of Science' title='Game of Life in A New Kind of Science' width='452' height='576'/></a></p>\n<p>And, yes, it was immediately striking how similar the spacetime slice looked to my pictures of 1D class 4 cellular automata. And when I wrote a <a href=\"https://www.wolframscience.com/nksonline/page-964f/\">note for the end of the book about Life</a>, the correspondence became even more obvious. I’d always seen the glider gun as a movie. But in a spacetime slice it “made much more sense”, and looked incredibly similar to analogous structures in 1D class 4 cellular automata:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/NKS-page2.png' alt='Different glider guns' title='Different glider guns' width='550' height='841'/></p>\n<p>In <em>A New Kind of Science</em> I put a lot of effort into <a href=\"https://www.wolframscience.com/reference/notes/\">historical notes</a>. And as a part of such a note on “<a href=\"https://www.wolframscience.com/nks/notes-2-3--history-of-cellular-automata/\">History of cellular automata</a>” I had a paragraph about the Game of Life:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg14.png' alt='Historical note' title='Historical note' width='422' height='390'/></p>\n<p>I first met John Conway in September 1983 (at a conference in the south of France). As I would <a href=\"https://archive.org/details/geniusatplaycuri0000robe/page/150\" target=\"_blank\">tell his biographer many years later</a>, my relationship with Conway was complicated from the start. We were both drawn to systems defined by very simple rules, but what we found interesting about them was very different. I wanted to understand the big picture and to explore science-oriented questions (and what I would now call <a href=\"https://writings.stephenwolfram.com/category/ruliology\">ruliology</a>). Conway, on the other hand, was interested in specific, often whimsically presented results—and in questions that could be couched as mathematical theorems.</p>\n<p>In my conversations with Conway, the Game of Life would sometimes come up, but Conway never seemed too interested in talking about it. In 2001, though, when I was writing my note about the history of 2D cellular automata, I spent several hours specifically asking Conway about the Game of Life and its history. At first Conway told me the standard origin story that Life had arisen as a kind of game. A bit later he said he’d at the time just been hired as a logic professor, and had wanted to use Life as a simple way to enumerate the recursive functions. In the end, it was hard to disentangle true recollections from false (or “elaborated”) ones. And, notably, when asked directly about the origin of the specific rules of Life, he was evasive. Of course, none of that should detract from Conway’s achievement in the concept of the Game of Life, and in the definition of the hacker-like culture around it—the fruits of which have now allowed me to do what I’ve done here.</p>\n<p>For many years after the publication of <em>A New Kind of Science</em> in 2002, I didn’t actively engage with the Game of Life—though I would hear from Life enthusiasts with some frequency, but none as much as Gosper, from whom I was a recipient of hundreds of messages about Life, a typical example from 2017 concerning</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/03/sw03142025backstoryimg15.png' alt='' title='' width='307' height='359'> </div>\n</p></div>\n<p>and saying:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Re: Unlimited(?) novelty from just two LWSS backrakes</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\n<p>Novelty is mediated by the sporadic glider gas (which forms very sparse<br />\nbeams), sporadic debris (forming sparse lines), and is hidden in sporadic<br />\ndefects in the denser beams and lines.

It was a big <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-2--the-need-for-a-new-intuition\">shock to my intuition</a> at the beginning of the 1980s when I began to see <a href=\"https://www.wolframscience.com/nks/p23--how-do-simple-programs-behave/\">all the richness that even very simple programs can produce</a>. And it made me start to wonder about all our technological and other achievements. With our goals and intentions, were we producing things that were somehow <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-10--intelligence-in-the-universe\">different from what even simple programs “could do anyway”</a>? How would we be able to tell whether that interstellar radio signal was the product of some sophisticated civilization, or just something that “happened naturally”? My <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> implied that at an ultimate level there wouldn’t really be a way to tell. But I kept on wondering whether there might at least be some signature of “purposes like ours” that we could detect.</p>\n<p>At first it was <a href=\"https://writings.stephenwolfram.com/2018/01/showing-off-to-the-universe-beacons-for-the-afterlife-of-our-civilization/\">extraterrestrial intelligence and animal intelligence</a>, later also <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">artificial intelligence</a>. But the question kept on coming back: what distinguishes what’s engineered from what just “scientifically happens”? (And, yes, there was a <a href=\"https://www.wolframscience.com/nks/notes-12-12--universe-as-intelligent/\">theological question in there too</a>.) I had wondered for a while about using the Game of Life as a testing ground for this, and as the 50th anniversary of the Game of Life approached in 2018, I took this as a cue to explore it. </p>\n<p>Over the years I had accumulated a <a href=\"https://writings.stephenwolfram.com/2019/02/seeking-the-productive-life-some-details-of-my-personal-infrastructure/#archiving-and-searching\">paper file</a> perhaps 6 inches thick about the Game of Life (a few samples from which I’ve shown above). But looking around the web I was impressed at how much well-organized material there now was out there about the Game of Life. I started to try to analyze it, imagining that I might see something like an analog of Moore’s law. Meanwhile, over the preceding decade I had <a href=\"https://writings.stephenwolfram.com/category/historical-perspectives\">written a lot about the history of science</a>, and I thought that as part of my contribution to the 50th anniversary of the Game of Life I should try to write about its history. What were the stories of all those people whose names were attached to discoveries in Life? A research assistant of mine began to track them down, and interview them. It turned out to be a very disparate group, many of whom knew little about each other. (Though they often, but not always, had in common graduate-level education in math.) And in any case it became clear that writing a coherent history was going to be a huge undertaking. In addition, the first few ways I tried to discern trends in data about the Game of Life data didn’t yield much. And soon the 50th anniversary had passed—and I got busy with other things. </p>\n<p>But the project of studying the “metaengineering” of the Game of Life stayed on my “to do” list (and a couple of students at our <a href=\"https://education.wolfram.com/summer-school/\">Wolfram Summer School</a> worked on it). Then in 2022 a <a href=\"https://conwaylife.com/book/conway_life_book.pdf\" target=\"_blank\" rel=\"noopener\">nice book on the Game of Life</a> came out (by Nathaniel Johnston and Dave Greene, the latter of whom had actually <a href=\"https://education.wolfram.com/summer-school/alumni/2011/greene/\">been at our Summer School back in 2011</a>). Had my project been reduced to just reading this book, I wondered. I soon realized that it hadn’t. And there were now all kinds of questions on which I imagined a study of the Game of Life could shed light. Not only questions about the “signature of purpose”. But also questions about novelty and creativity. And about the arc and rhythm of innovation. </p>\n<p>Then in 2024 came the surprises of my work on <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">biological evolution</a>, and on <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">machine learning</a>. And I found myself again wondering about how things work when there’s “intentional engineering”. And so I finally decided to do my long-planned study of the Game of Life. There’s much, much more that can be done. But I think what I’ve done here provides an indication of some of the directions one can go, and some of what there is to discover in what is effectively the new field of “computational metaengineering”. </p>\n<h2 id=\"notes\" style='font-size:1.2rem'>Notes</h2>\n<p style='font-size:90%'>Thanks to Willem Nielsen of the <a href=\"https://www.wolframinstitute.org/\" target=\"_blank\">Wolfram Institute</a> for extensive help, as well as to Ed Pegg of Wolfram Research.

But might it also be possible to talk about medicine in a more general, more abstract way—and perhaps to create a framework in which one can study its essential features without engaging with all of its details?</p>\n<p>My goal here is to take the first steps towards such a framework. And in a sense my central result is that there are many broad phenomena in medicine that seem at their core to be fundamentally computational—and to be captured by remarkably simple computational models that are readily amenable to study by computer experiment.</p>\n<p>I should make it clear at the outset that I’m not trying to set up a specific model for any particular aspect or component of biological systems. Rather, my goal is to “zoom out” and create what one can think of as a “metamodel” for studying and formalizing the abstract foundations of medicine.<span id=\"more-66885\"></span></p>\n<p>What I’ll be doing builds on my recent work on using the <a href=\"https://www.wolframscience.com/nksonline/toc.html\">computational paradigm</a> to study the <a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/\">foundations of biological evolution</a>. And indeed in constructing idealized organisms we’ll be using the <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">very same class of basic computational models</a>. But now, instead of considering idealized genetic mutations and asking what types of idealized organisms they produce, we’re going to be looking at specific evolved idealized organisms, and seeing what effect perturbations have on them. Roughly, the idea is that an idealized organism operates in its normal “healthy” way if there are no perturbations—but perturbations can “derail” its operation and introduce what we can think of as “disease”. And with this setup we can then think of the “fundamental problem of medicine” as being the identification of additional perturbations that can “treat the disease” and put the organism at least approximately back on its normal “healthy” track.</p>\n<p>As we’ll see, most perturbations lead to lots of detailed changes in our idealized organism, much as perturbations in biological organisms normally lead to vast numbers of effects, say at a molecular level. But as in medicine, we can imagine that all we can observe (and perhaps all we care about) are certain coarse-grained features or “symptoms”. And the fundamental problem of medicine is then to work out from these symptoms what “treatment” (if any) will end up being useful. (By the way, when I say “symptoms” I mean the whole cluster of signs, symptoms, tests, etc. that one might in practice use, say for diagnosis.)</p>\n<p>It’s worth emphasizing again that I’m not trying here to derive specific, actionable, medical conclusions. Rather, my goal is to build a conceptual framework in which, for example, it becomes conceivable for general phenomena in medicine that in the past have seemed at best vague and anecdotal to begin to be formalized and studied in a systematic way. At some level, what I’m trying to do is a bit like what Darwinism did for biological evolution. But in modern times there’s a critical new element: the computational paradigm, which not only introduces all sorts of new, powerful theoretical concepts, but also leads us to the practical methodology of computer experimentation. And indeed much of what follows is based on the (often surprising) results of computer experiments I’ve recently done that give us raw material to build our intuition—and structure our thinking—about fundamental phenomena in medicine. </p>\n<h2 id=\"a-minimal-metamodel\">A Minimal Metamodel</h2>\n<p>How can we make a metamodel of medicine? We need an idealization of biological organisms and their behavior and development. We need an idealization of the concept of disease for such organisms. And we need an idealization of the concept of treatment. </p>\n<p>For our idealization of biological organisms we’ll use a class of simple computational systems called <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-1--how-do-simple-programs-behave\">cellular automata</a> (that I happen to have <a href=\"https://www.wolframscience.com/nks/chap-1--the-foundations-for-a-new-kind-of-science#sect-1-4--the-personal-story-of-the-science-in-this-book\">studied since the early 1980s</a>). Here’s a specific example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg1.png' alt='' title='' width='461' height='513'> </div>\n</p></div>\n<p>What’s going on here is that we’re progressively constructing the pattern on the left (representing the development and behavior of our organism) by repeatedly applying cases of the rules on the right (representing the idealized genome—and other biochemical, etc. rules—of our organism). Roughly we can think of the pattern on the left as corresponding to the “life history” of our organism—growing, developing and eventually dying as it goes down the page. And even though there’s a rather organic look to the pattern, remember that the system we’ve set up isn’t intended to provide a model for any particular real-world biological system. Rather, the goal is just for it to capture enough of the foundations of biology that it can serve as a successful metamodel to let us explore our questions about the foundations of medicine.</p>\n<p>Looking at our model in more detail, we see that it involves a grid of squares—or “cells” (computational, not biological)—each having one of 4 possible colors (white and three others). We start from a single red “seed” cell on the top row of the grid, then compute the colors of cells on subsequent steps (i.e. on subsequent rows down the page) by successively applying the rules on the right. The rules here are basically very simple. But we can see that when we run them they lead to a fairly complicated pattern—which in this case happens to “die out” (i.e. all cells become white) after exactly 101 steps. </p>\n<p>So what happens if we perturb this system? On the left here we’re showing the system as above, without perturbation. But on the right we’re introducing a perturbation by changing the color of a particular cell (on step 16)—leading to a rather different (if qualitatively similar) pattern:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg2.png' alt='' title='' width='543' height='446'> </div>\n</p></div>\n<p>Here are the results of some other perturbations to our system:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg3.png' alt='' title='' width='666' height='329'> </div>\n</p></div>\n<p>Some perturbations (like the one in the second panel here) quickly disappear; in essence the system quickly “heals itself”. But in most cases even single-cell perturbations like the ones here have a long-term effect. Sometimes they can “increase the lifetime” of the organism; often they will decrease it. And sometimes—like in the last case shown here—they will lead to essentially unbounded “tumor-like” growth.</p>\n<p>In biological or medical terms, the perturbations we’re introducing are minimal idealizations of “things that can happen to an organism” in the course of its life. Sometimes the perturbations will have little or no effect on the organism. Or at least they won’t “really hurt it”—and the organism will “live out its natural life” (or even extend it a bit). But in other cases, a perturbation can somehow “destabilize” the organism, in effect “making it develop a disease”, and often making it “die before its time”.</p>\n<p>But now we can formulate what we can think of as the “fundamental problem of medicine”: given that perturbations have had a deleterious effect on an organism, can we find subsequent perturbations to apply that will serve as a “treatment” to overcome the deleterious effect?</p>\n<p>The first panel here shows a particular perturbation that makes our idealized organism die after 47 steps. The subsequent panels then show various “treatments” (i.e. additional perturbations) that serve at least to “keep the organism alive”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025minimalimg4.png' alt='' title='' width='637' height='227'> </div>\n</p></div>\n<p>In the later panels here the “life history” of the organism gets closer to the “healthy” unperturbed form shown in the final panel. And if our criterion is restoring overall lifetime, we can reasonably say that the “treatment has been successful”. But it’s notable that the detailed “life history” (and perhaps “quality of life”) of the organism will essentially never be the same as before: as we’ll see in more detail later, it’s almost inevitably the case that there’ll be at least some (and often many) long-term effects of the perturbation+treatment even if they’re not considered deleterious.</p>\n<p>So now that we’ve got an idealized model of the “problem of medicine”, what can we say about solving it? Well, the main thing is that we can get a sense of why it’s fundamentally hard. And beyond anything else, the central issue is a fundamentally computational one: the phenomenon of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>. </p>\n<p>Given any particular cellular automaton rule, with any particular initial condition, one can always explicitly run the rule, step by step, from that initial condition, to see what will happen. But can one do better? Experience with mathematical science might make one imagine that as soon as one knows the underlying rule for a system, one should in principle immediately be able to “solve the equations” and jump ahead to work out everything about what the system does, without explicitly tracing through all the steps. But one of the central things I discovered in studying simple programs back in the early 1980s is that it’s common for such systems to show what I called computational irreducibility, which means that the only way to work out their detailed behavior is essentially just to run their rules step by step and see what happens.</p>\n<p>So what about biology? One might imagine that with its incremental optimization, biological evolution would produce systems that somehow <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#what-it-means-for-whats-going-on-in-biology\">avoid computational irreducibility</a>, and (like simple machinery) have obvious easy-to-understand mechanisms by which they operate. But in fact that’s not what biological evolution typically seems to produce. And instead—<a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/\">as I’ve recently argued</a>—what it seems to do is basically just to put together randomly found “lumps of irreducible computation” that happen to satisfy its fitness criterion. And the result is that biological systems are full of computational irreducibility, and mostly aren’t straightforwardly “mechanically explainable”. (The presence of computational irreducibility is presumably also why theoretical biology based on mathematical models has always been so challenging.)</p>\n<p>But, OK, given all this computational irreducibility, how is it that medicine is even possible? How is it that we can know enough about what a biological system will do to be able to determine what treatment to use on it? Well, computational irreducibility makes it hard. But it’s a fundamental feature of computational irreducibility that within any computationally irreducible process there must always be pockets of computational reducibility. And if we’re trying to achieve only some fairly coarse objective (like maximizing overall lifetime) it’s potentially possible to leverage some pocket of computational reducibility to do this. </p>\n<p>(And indeed pockets of computational reducibility within computational irreducibility are what make many things possible—including having <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">understandable laws of physics</a>, doing <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/\">higher mathematics</a>, etc.) </p>\n<h2 id=\"the-diversity-and-classification-of-disease\">The Diversity and Classification of Disease</h2>\n<p>With our simple idealization of disease as the effect of perturbations on the life history of our idealized organism, we can start asking questions like “What is the distribution of all possible diseases?” </p>\n<p>And to begin exploring this, here are the patterns generated with a random sample of the 4383 possible single-point perturbations to the idealized organism we’ve discussed above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg1.png' alt='' title='' width='647' height='537'> </div>\n</p></div>\n<p>Clearly there’s a lot of variation in these life histories—in effect a lot of different symptomologies.

And we can imagine also doing this in our simple model. But it’s already clear from the array of pictures above that this is not going to be a straightforward task. We’ve got a different detailed pattern for every different perturbation. So how should we group them together?</p>\n<p>Well—much as in medicine—it depends on what we care about. In medicine we might talk about signs and symptoms, which in our idealized model we can basically identify with features of patterns. And as an example, we might decide that the only features that matter are ones associated with the boundary shape of our pattern:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg4.png' alt='' title='' width='175' height='248'> </div>\n</p></div>\n<p>So what happens to these boundary shapes with different perturbations?

But what if we look at all possible “diseases”—at least all the ones produced by single-cell perturbations? Using boundary shape as our way to distinguish “diseases” we find that if we plot the frequency of diseases against their rank we get roughly a power law distribution (and, yes, it’s not clear <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#probabilistic-approximations\">why it’s a power law</a>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg6.png' alt='' title='' width='357' height='214'> </div>\n</p></div>\n<p>What are the “rare diseases” (i.e. ones with low frequency) like?

And we might imagine that if we set up enough tests, we could begin to discriminate between many discrete “diseases”. But somehow this seems quite ad hoc. </p>\n<p>So can we perhaps be more systematic by using machine learning? Let’s say we just look at each whole pattern, then try to place it in an image <a href=\"https://reference.wolfram.com/language/ref/FeatureSpacePlot.html\">feature space</a>, say a 2D one. Here’s an example of what we get:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg10.png' alt='' title='' width='619' height='625'> </div>\n</p></div>\n<p>The details of this depend on the particulars of the machine learning method we’ve used (here the default <tt><a href=\"http://reference.wolfram.com/language/ref/FeatureSpacePlot.html\">FeatureSpacePlot</a></tt> method in <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>). But it’s a fairly robust result that “visually different” patterns end up separated—so that in effect the machine learning is successfully automating some kind of “visual diagnosis”. And there’s at least a little evidence that the machine learning will identify separated clusters of patterns that we can reasonably identify as “truly distinct diseases”—even as the more common situation is that between any two patterns, there are intermediate ones that aren’t neatly classified as one disease or the other.</p>\n<p>Somewhat in the style of the human “International Classification of Diseases” (ICD), we can try arranging all our patterns in a hierarchy—though it’s basically inevitable that we’ll always be able to subdivide further, and there’ll never be a clear point at which we can say “we’ve classified all the diseases”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02032025treeclusterAimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg11.png' alt='' title='' width='605' height='382'> </div>\n</p></div>\n<p>By the way, in addition to talking about possible diseases, we also need to discuss what counts as “healthy”. We could say that our organism is only “healthy” if its pattern is exactly what it would be without any perturbation (“the natural state”). But what probably better captures everyday medical thinking is to say that our organism should be considered “healthy” if it doesn’t have symptoms (or features) that we consider bad. And in particular, at least “after the fact” we might be able to say that it must have been healthy if its lifetime turned out to be long. </p>\n<p>It’s worth noting that even in our simple model, while there are many perturbations that reduce lifetime, there are also perturbations that increase lifetime. In the course of biological evolution, genetic mutations of the overall underlying rules for our idealized organism might have managed to achieve a certain longevity. But the point is that nothing says “longevity perturbations” applied “during the life of the organism” can’t get further—and indeed here are some examples where they do:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg12.png' alt='' title='' width='565' height='267'> </div>\n</p></div>\n<p>And, actually, in a feature that’s not (at least yet) reflected in human medicine, there are perturbations than can make the lifetime very significantly longer.

And indeed such cases might remind us of tumor-like behavior in biological organisms. But what about a case that not only lives forever, but also grows forever? Well, needless to say, lurking out in the computational universe, one can find an example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg22_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diversityimg22.png' alt='' title='' width='535' height='315'> </div>\n</p></div>\n<p>The “incidence” of this behavior is about one in a million for 2 perturbations (or, more precisely, 7 out of 9.6 million possibilities), and one in 300,000 for 3 perturbations. And although there presumably are even more complicated behaviors out there to find, they don’t show up with 2 perturbations, and their incidence with 3 perturbations is below about one in 100 million. </p>\n<h2 id=\"diagnosis--prognosis\">Diagnosis & Prognosis</h2>\n<p>A fundamental objective in medicine is to predict from tests we do or symptoms and signs we observe what will happen. And, yes, we now know that computational irreducibility inevitably makes this in general hard. But also know from experience that a certain amount of prediction is possible—which we can now interpret as successfully managing to tap into pockets of computational reducibility.</p>\n<p>So as an example, let’s ask what the prognosis is for our idealized organism based on the width of its pattern we measure at a certain step. So here, for example, is what happens to the original lifetime distribution (in green) if we consider only cases where the width of the measured pattern after 25 steps is less than its unperturbed (“healthy”) value (and where we’re dropping the 1% of cases when the organism was “already dead” before 25 steps):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg1.png' alt='' title='' width='360' height='164'> </div>\n</p></div>\n<p>Our “narrow” cases represent about 5% of the total. Their median lifetime is 57, as compared with the overall median of 106. But clearly the median alone does not tell the whole story. And nor do the two survival curves:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg2.png' alt='' title='' width='358' height='160'> </div>\n</p></div>\n<p>And, for example, here are the actual widths as a function of time for all the narrow cases, compared to the sequence of widths for the unperturbed case:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg3.png' alt='' title='' width='617' height='139'> </div>\n</p></div>\n<p>These pictures don’t make it look promising that one could predict lifetime from the single test of whether the pattern was narrow at step 25. Like in analogous medical situations, one needs more data. One approach in our case is to look at actual “narrow” patterns (up to step 25)—here sorted by ultimate lifetime—and then to try to identify useful predictive features (though, for example, to attempt any serious machine learning training would require a lot more examples): </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg4.png' alt='' title='' width='634' height='227'> </div>\n</p></div>\n<p>But perhaps a simpler approach is not just to do a discrete “narrow or not” test, but rather to look at the actual width at step 25.

And, unsurprisingly, machine learning doesn’t help. Like here’s a <a href=\"https://reference.wolfram.com/language/ref/Predict.html\">machine learning prediction</a> (based on decision tree methods) for lifetime as a function of width (that, yes, is very close to just being the median):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg7.png' alt='' title='' width='311' height='202'> </div>\n</p></div>\n<p>Does it help if we use more history? In other words, what happens if we make our prediction not just from the width at a particular step, but from the history of all widths up to that point? As one approach, we can make a collection of “training examples” of what lifetimes particular “width histories” (say up to step 25) lead to:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/02/sw01312025diagnosisimg8A.png' alt='' title='' width='663' height='121'> </div>\n</p></div>\n<p>There’s already something of an issue here, because a given width history—which, in a sense is a “coarse graining” of the detailed “microscopic” history—can lead to multiple different final lifetimes:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/02/sw02032525diagnosisbracesimg9.png' alt='' title='' width='596' height='49'> </div>\n</p></div>\n<p>But we can still go ahead and try to use machine learning to predict lifetimes from width histories based on training on (say, half) of our training data—yielding less than impressive results (with the vertical line being associated with multiple lifetimes from a single width history in the training data):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025diagnosisimg10.png' alt='' title='' width='357' height='160'> </div>\n</p></div>\n<p>So how can we do better? Well, given the underlying setup for our system, if we could determine not just the width but the whole precise sequence of values for all cells, even just at step 25, then in principle we could use this as an “initial condition” and run the system forward to see what it does. But regardless of it being “medically implausible” to do this, it isn’t much of a prediction anyway; it’s more just “watch and see what happens”. And the point is that insofar as there’s computational irreducibility, one can’t expect—at least in full generality—to do much better. (And, as we’ll argue later, there’s no reason to think that organisms produced by biological evolution will avoid computational irreducibility at this level.)</p>\n<p>But still, within any computationally irreducible system, there are always pockets of computational reducibility. So we can expect that there will be some predictions that can be made. But the question is whether those predictions will be about things we care about (like lifetime) or even about things we can measure. Or, in other words, will they be predictions that speak to things like symptoms? </p>\n<p>Our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a>, for example, involves all sorts of underlying processes that are computationally irreducible. But the key point there is that what <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">physical observers like us</a> perceive are aggregate constructs (like overall features of space) that show significant computational reducibility. And in a sense there’s an analogous issue here: there’s computational irreducibility underneath, but what do “medical observers” actually perceive, and are there computationally reducible features related to that? If we could find such things, then in a sense we’d have identified “general laws of medicine” much like we now have “general laws of physics”. </p>\n<h2 id=\"the-problem-of-finding-treatments\">The Problem of Finding Treatments</h2>\n<p>We’ve talked a bit about giving a prognosis for what will happen to an idealized organism that’s suffered a perturbation.

But let’s (as we can in our idealized model) just enumerate all possible second perturbations (here 1554 of them).

Well, it depends on what we mean. Yes, they’ve managed to make the lifetime exactly what it would have been without the original “disease-inducing” perturbation. But in essentially all cases we see here that there are various “long-term side effects”—in the sense that the detailed patterns generated end up having obvious differences from the original unperturbed “healthy” form.</p>\n<p>The one exception here is the very first case, in which the “disease was caught early enough” that the “treatment perturbation” manages to completely heal the effects of the “disease perturbation”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg4.png' alt='' title='' width='382' height='329'> </div>\n</p></div>\n<p>We’ve been talking here about intervening with “treatment perturbations” to “heal” our “disease perturbation”.

They’re like seeds for diseases that never take hold, or like diseases that quickly burn themselves out. But from a theoretical point of view we can think of them as being where the unperturbed life history of our idealized organism is acting as <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-7--the-notion-of-attractors\">attractor</a>, to which certain perturbed states inexorably converge—a bit like how friction can dissipate perturbations to patterns of motion in a mechanical system. </p>\n<p>But let’s say we have a perturbation that doesn’t “spontaneously heal itself”. Then to remediate it we have to “do the medical thing” and in our idealized model try to find a “treatment perturbation”. So how might we systematically set about doing that? Well, in general, computational irreducibility makes it difficult. And as one indication of this, this shows what lifetime is achieved by “treatment perturbations” made at each possible point in the pattern (after the initial perturbation):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg8B.png' alt='' title='' width='380' height='295'> </div>\n</p></div>\n<p>We can think of this as providing a map of what the effects of different treatment perturbations will be.

But the main observation is that different detailed choices of treatment perturbations will often have very different effects. In other words, even “nearby treatments” will often lead to very different outcomes. Given computational irreducibility, this isn’t surprising. But in a sense it underscores the difficulty of finding and applying “treatments”. By the way, cells indicated in dark red above are ones where treatment leads to a pattern that lives “excessively long”—or in effect shows tumor-like characteristics. And the fact that these are scattered so seemingly randomly reflects the difficulty of predicting whether such effects will occur as a result of treatment.</p>\n<p>In what we’ve done so far here, our “treatment” has always consisted of just a single additional perturbation. But what about applying more perturbations? For example, let’s say we do a series of experiments where after our first “treatment perturbation” we progressively try other treatment perturbations. If a given additional perturbation doesn’t get further from the desired lifetime, we keep it. Otherwise we reject it, and try another perturbation. Here’s an example of what happens if we do this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg9.png' alt='' title='' width='661' height='192'> </div>\n</p></div>\n<p>The highlighted panels represent perturbations we kept.

But what if we require treatment perturbations to always be added on successive steps—starting right after the “disease perturbation” occurred? Here’s an example of what happens in this case:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg11.png' alt='' title='' width='503' height='192'> </div>\n</p></div>\n<p>And here’s what we see zooming in at the beginning:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg12.png' alt='' title='' width='523' height='196'> </div>\n</p></div>\n<p>In a sense this corresponds to “doing aggressive treatment” as soon as the initial “disease perturbation” has occurred. And a notable feature of the particular example here is that when our succession of treatment perturbations have succeeded in “restoring the lifetime” (which happens fairly quickly), the life history they produce is similar (though not identical) to the original unperturbed case. </p>\n<p>That definitely doesn’t always happen, as this example illustrates—but it’s fairly common:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025problemimg13.png' alt='' title='' width='464' height='192'> </div>\n</p></div>\n<p>It’s worth pointing out that if we allowed ourselves to do many single perturbations at the same time (i.e. on the same row of the pattern) we could effectively just “define new initial conditions” for the pattern, and, for example, perfectly “regenerate” the original unperturbed pattern after this “reset”. And in general we can imagine in effect “hot-wiring” the organism by applying large numbers of treatment perturbations that just repeatedly direct it back to its unperturbed form.</p>\n<p>But such extensive and detailed “intervention”—that in effect replaces the whole state of the organism—seems far from what might be practical in typical (current) medicine (except perhaps in some kind of “regenerative treatment”). And indeed in actual (current) medicine one is normally operating in a situation where one does not have anything close to perfect “cell-by-cell” information on the state of an organism—and instead one has to figure out things like what treatment to give based on much coarser “symptom-level” information. (In some ways, though, the immune system does something closer to cell-by-cell “treatment”.)</p>\n<p>So what can one do given coarse-grained information? As one example, let’s consider trying to predict what treatment perturbation will be best using the kind of pattern-width information we discussed above. Specifically, let’s say that we have the history of the overall width of a pattern up to a particular point, then from this we want to predict what treatment perturbation will lead to the best lifetime outcome for the system. There are a variety of ways we could approach this, but one is to make predictions of where to apply a treatment perturbation using machine learning trained on examples of optimal such perturbations.</p>\n<p>This is analogous to what we did in the previous section in applying machine learning to predict lifetime from width history. But now we want to predict from width history what treatment perturbation to apply. To generate our training data we can search for treatment perturbations that lead to the unperturbed lifetime when starting from life histories with a given width history. Now we can use a simple neural net to create a predictor that tries to tell us from a width history what “treatment to give”. And here are comparisons between our earlier search results based on looking at complete life histories—and (shown with red arrows) the machine learning predictions based purely on width history before the original disease perturbation:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02032025problemnewimg14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/02/sw02032025problemnewimg14.png' alt='' title='' width='637' height='381'> </div>\n</p></div>\n<p>It’s clear that the machine learning is doing something—though it’s not as impressive as perhaps it looks, because a wide range of perturbations all in fact give rather similar life histories. So as a slightly more quantitative indication of what’s going on, here’s the distribution of lifetimes achieved by our machine-learning-based therapy:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02032025problemnewimg15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/02/sw02032025problemnewimg15.png' alt='' title='' width='398' height='174'> </div>\n</p></div>\n<p>Our “best treatment” was able to give lifetime 101 in all these cases. And while the distribution we’ve now achieved looks peaked around the unperturbed value, dividing this distribution by what we’d get without any treatment at all makes it clear that not so much was achieved by the machine learning we were able to do: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02032025problemnewimg16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/02/sw02032025problemnewimg16.png' alt='' title='' width='357' height='160'> </div>\n</p></div>\n<p>And in a sense this isn’t surprising; our machine learning—based, as it is, on coarse-grained features—is <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/\">quite weak compared to the computational irreducibility</a> of the underlying processes at work.</p>\n<h2 id=\"the-effect-of-genetic-diversity\">The Effect of Genetic Diversity</h2>\n<p>In what we’ve done so far, we’ve studied just a single idealized organism—with a single set of underlying “genetic rules”. But in analogy to the situation with humans, we can imagine a whole population of genetically slightly different idealized organisms, with different responses to perturbations, etc. </p>\n<p>Many changes to the underlying rules for our idealized organism will lead to unrecognizably different patterns, that don’t, for example, have the kind of finite-but-long lifetimes we’ve been interested in. But it turns out that in the rules for our particular idealized organism there are some specific changes that actually don’t have any effect at all—at least on the unperturbed pattern of behavior. And the reason for this is that in generating the unperturbed pattern these particular cases in the rule happen never to be used:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025geneticimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025geneticimg1.png' alt='' title='' width='576' height='115'> </div>\n</p></div>\n<p>And the result is that any one of the 4<sup>3</sup> = 64 possible choices of outcomes for those cases in the rule will still yield the same unperturbed pattern. If there’s a perturbation, however, different cases in the rule can be sampled—including these ones. It’s as if cases in the rule that are initially “non-coding” end up being “coding” when the path of behavior is changed by a perturbation. (Or, said differently, it’s like different genes being activated when conditions are different.)</p>\n<p>So to make an idealized model of something like a population with genetic diversity, we can look at what happens with different choices of our (initially) “non-coding” rule outcomes:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025geneticimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025geneticimg3.png' alt='' title='' width='572' height='372'> </div>\n</p></div>\n<p>Before the perturbation, all these inevitably show the same behavior, because they’re never sampling “non-coding” rule cases.

But how does it affect “treatment”? For the “disease” above, we already saw that there’s a particular “treatment perturbation” that successfully returns our original idealized organism to its “natural lifespan”. So what happens if we apply this same treatment across all the genetic variants? In effect this is like doing a very idealized “clinical trial” of our potential treatment. And what we see is that the results are quite diverse—and indeed more diverse than from the disease on it own:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025geneticimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025geneticimg10.png' alt='' title='' width='613' height='535'> </div>\n</p></div>\n<p>In essence what we’re seeing is that, yes, there are some genetic variants for which the treatment still works. But there are many for which there are (often fairly dramatic) side effects. </p>\n<h2 id=\"biological-evolution-and-our-model-organism\">Biological Evolution and Our Model Organism</h2>\n<p>So where did the particular rule for the “model organism” we’ve been studying come from? Well, we evolved it—using a slight generalization of the idealized model for biological evolution that <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">I recently introduced</a>. The goal of our evolutionary process was to find a rule that generates a pattern that lives as long as possible, but not infinitely long—and that does so robustly even in the presence of perturbations. In essence we used lifetime (or, more accurately, “lifetime under perturbation”) as our “fitness function”, then progressively evolved our rule (or “genome”) by random mutations to try to maximize this fitness function.</p>\n<p>In more detail, we started from the null (“everything turns white”) rule, then successively made random changes to single cases in the rule (“point mutations”)—keeping the resulting rule whenever the pattern it generated had a lifetime (under perturbation) that wasn’t smaller (or infinite). And with this setup, here’s the particular (random) sequence of rules we got (showing for each rule the outcome for each of its 64 cases):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg1.png' alt='' title='' width='384' height='224'> </div>\n</p></div>\n<p>Many of these rules don’t “make progress” in the sense that they increase the lifetime under perturbation. But every so often there’s a “breakthrough”, and a rule with a longer lifetime under perturbation is reached:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg2.png' alt='' title='' width='568' height='473'> </div>\n</p></div>\n<p>And, as we see, the rule for the particular model organism we’ve been using is what’s reached at the end.</p>\n<p>In <a href=\"https://writings.stephenwolfram.com/2024/12/foundations-of-biological-evolution-more-results-more-surprises/\">studying my recent idealized model for biological evolution</a>, I considered fitness functions like lifetime that can directly be computed just by running the underlying rule from a certain initial condition. But here I’m generalizing that a bit, and considering as a fitness function not just lifetime, but “lifetime under perturbation”, computed by taking a particular rule, and finding the minimum lifetime of all patterns produced by it with certain random perturbations applied. </p>\n<p>So, for example, here the “lifetime under perturbation” would be considered to be the minimum of the lifetimes generated with no perturbation, and with certain random perturbations—or in this case 60:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg3.png' alt='' title='' width='618' height='177'> </div>\n</p></div>\n<p>This plot then illustrates how the (lifetime-under-perturbation) fitness (indicated by the blue line) behaves in the course of our adaptive evolution process, right around where the fitness-60 “breakthrough” above occurs:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg4.png' alt='' title='' width='638' height='233'> </div>\n</p></div>\n<p>What’s happening in this plot? At each adaptive step, we’re considering a new rule, obtained by a point mutation from the previous one. Running this rule we get a certain lifetime. If this lifetime is finite, we indicate it by a green dot. Then we apply a certain set of random perturbations—indicating the lifetimes we get by gray dots. (We could imagine using all sorts of schemes for picking the random perturbations; here what we’re doing is to perturb random points on about a tenth of the rows in the unperturbed pattern.) </p>\n<p>Then the minimum lifetime for any given rule we indicate by a red dot—and this is the fitness we assign to that rule. So now we can see the whole progression of our adaptive evolution process:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg5.png' alt='' title='' width='667' height='242'> </div>\n</p></div>\n<p>One thing that’s notable is that the unperturbed lifetimes (green dots) are considerably larger than the final minimum lifetimes (red dots). And what this means is that our requirement of “robustness”, implemented by looking at lifetime under perturbation rather than just unperturbed lifetime, considerably reduces the lifetimes we can reach. In other words, if our idealized organism is going to be robust, it won’t tend to be able to have as long a lifetime as it could if it didn’t have to “worry about” random perturbations.</p>\n<p>And to illustrate this, here’s a typical example of a much longer lifetime obtained by adaptive evolution with the same kind of rule we’ve been using (<em>k</em> = 4, <em>r</em> = 1 cellular automaton), but now with no perturbations and with fitness being given purely by the unperturbed lifetime (exactly as in my recent work on biological evolution):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg6.png' alt='' title='' width='579' height='622'> </div>\n</p></div>\n<p>OK, so given that we’re evolving with a lifetime-under-perturbation fitness function, what are some alternatives to our particular model organism? Here are a few examples:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg7.png' alt='' title='' width='595' height='512'> </div>\n</p></div>\n<p>At an overall level, these seem to react to perturbations much like our original model organism: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg8.png' alt='' title='' width='660' height='670'> </div>\n</p></div>\n<p>One notable feature here, though, is that there seems to be a tendency for simpler overall behavior to be less disrupted by perturbations. In other words, our idealized “diseases” seem to have less dramatic effects on “simpler” idealized organisms. And we can see a reflection of this phenomenon if we plot the overall (single-perturbation) lifetime distributions for the four rules above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01312025evolutionimg9.png' alt='' title='' width='636' height='72'> </div>\n</p></div>\n<p>But despite detailed differences, the main conclusion seems to be that there’s nothing special about the particular model organism we’ve used—and that if we repeated our whole analysis for different model organisms (i.e. “different idealized species”) the results we’d get would be very much the same. </p>\n<h2 id=\"what-it-means-and-where-to-go-from-here\">What It Means and Where to Go from Here</h2>\n<p>So what does all this mean? At the outset, it wasn’t clear there’d be a way to usefully capture anything about the foundations of medicine in a formalized theoretical way. But in fact what we’ve found is that even the very simple computational model we’ve studied seems to successfully reflect all sorts of features of what we see in medicine. Many of the fundamental effects and phenomena are, it seems, not the result of details of biomedicine, but instead are at their core purely abstract and computational—and therefore accessible to formalized theory and metamodeling. This kind of methodology is very different from what’s been traditional in medicine—and isn’t likely to lead directly to specific practical medicine. But what it can do is to help us develop powerful new general intuition and ways of reasoning—and ultimately an understanding of the conceptual foundations of what’s going on.</p>\n<p>At the heart of much of what we’ve seen is the very fundamental—and ubiquitous—phenomenon of computational irreducibility. I’ve <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">argued recently</a> that computational irreducibility is central to what makes biological evolution work—and that it’s inevitably imprinted on the core “computational architecture” of biological organisms. And it’s this computational irreducibility that inexorably leads to much of the complexity we see so ubiquitously in medicine. Can we expect to find a simple narrative explanation for the consequences of some perturbation to an organism? In general, no—because of computational irreducibility. There are always pockets of computational reducibility, but in general we can have no expectation that, for example, we’ll be able to describe the effects of different perturbations by neatly classifying them into a certain set of distinct “diseases”. </p>\n<p>To a large extent the core mission of medicine is about “treating diseases”, or in our terms, about remediating or reversing the effects of perturbations. And once again, computational irreducibility implies there’s inevitably a certain fundamental difficulty in doing this. It’s a bit like with the <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">Second Law of thermodynamics</a>, where there’s enough computational irreducibility in microscopic molecular dynamics that to seriously reverse—or outpredict—this dynamics is something that’s at least far out of range for computationally bounded observers like us. And in our medical setting the analog of that is that “computationally bounded interventions” can only systematically lead to medical successes insofar as they tap into pockets of computational reducibility. And insofar as they are exposed to overall computational irreducibility they will inevitably seem to show a certain amount of apparent randomness in their outcomes. </p>\n<p>In traditional approaches to medicine one ultimately tends to “give in to the randomness” and go no further than to assign probabilities to things. But an important feature of what we’ve done here is that in our idealized computational models we can always explicitly see what’s happening inside. Often—largely as a consequence of computational irreducibility—it’s complicated. But the fact that we can see it gives us the opportunity to get much more clarity about the fundamental mechanisms involved. And if we end up summarizing what happens by giving probabilities and doing statistics it’s because this is something we’re choosing to do, not something we’re forced to do because of our lack of knowledge of the systems we’re studying. </p>\n<p>There’s much to do in our effort to explore the computational foundations of medicine. But already there are some implications that are beginning to emerge. Much of the workflow of medicine today is based on classifying things that can go wrong into discrete diseases. But what we’ve seen here (which is hardly surprising given practical experience with medicine) is that when one looks at the details, a huge diversity of things can happen—whose characteristics and outcomes can’t really be binned neatly into discrete “diseases”. </p>\n<p>And indeed when we try to figure out “treatments” the details matter. As a first approximation, we might base our treatments on coarse graining into discrete diseases. But—as the approach I’ve outlined here can potentially help us analyze—the more we can directly go from detailed measurements to detailed treatments (through computation, machine learning, etc.), the more promising it’s likely to be. Not that it’s easy. Because in a sense we’re trying to <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/#the-hard-limit-of-computational-irreducibility\">beat computational irreducibility</a>—with computationally bounded measurements and interventions.</p>\n<p>In principle one can imagine a future in which our efforts at treatment have much more computational sophistication (and indeed the immune system presumably already provides an example in nature). We can imagine things like algorithmic drugs and artificial cells that are capable of amounts of computation that are a closer match for the irreducible computation of an organism. And indeed the kind of formalized theory that I’ve outlined here is likely what one needs to begin to get an idea of how such an approach might work. (In the thermodynamic analogy, what we need to do is a bit like reversing entropy increase by sending in large numbers of “smart molecules”.) </p>\n<p>(By the way, seeing how difficult it potentially is to reverse the effects of a perturbation provides all the more impetus to consider “starting from scratch”—as nature does in successive generations of organisms—and simply wholesale regenerating elements of organisms, rather than trying to “fix what’s there”. And, yes, in our models this is for example like starting to grow again from a new seed, and letting the resulting pattern knit itself into the existing one.)</p>\n<p>One of the important features of operating at the level of computational foundations is that we can expect conclusions we draw to be very general. And we might wonder whether perhaps the framework we’ve described here could be applied outside of medicine. And to some extent I suspect it can—potentially to areas like robustness of large-scale technological and social systems and specifically things like computer security and computer system failures. (And, yes, much as in medicine one can imagine for example “classifying diseases” for computer systems.) But things likely won’t be quite the same in cases like these—because the underlying systems have much more human-determined mechanisms, and less “blind” adaptive evolution. </p>\n<p>But when it comes to medicine, the very presence of computational irreducibility introduced by biological evolution is what potentially allows one to develop a robust framework in which one can draw conclusions purely on the basis of abstract computational phenomena. Here I’ve just begun to scratch the surface of what’s possible. But I think we’ve already seen enough that we can be confident that medicine is yet another field whose foundations can be seen as fundamentally rooted in the computational paradigm. </p>\n<h2 id=\"thanks--notes\" style='font-size:1.2rem'>Thanks & Notes</h2>\n<p style='font-size:90%'>Thanks to <a href=\"https://wolframinstitute.org/\" target=\"_blank\" rel=\"noopener\">Wolfram Institute</a> researcher Willem Nielsen for extensive help.</p>\n<p style='font-size:90%'>I’ve never written anything substantial about medicine before, though I’ve had many interactions with the medical research and biomedical communities over the years—that have gradually extended my knowledge and intuition about medicine.

Today I’m pleased to announce that we’re releasing Version 14.2, delivering the latest from our R&D pipeline.</p>\n<p>This is an exciting time for our technology, both in terms of what we’re now able to implement, and in terms of how our technology is now being used in the world at large. A notable feature of these times is the increasing use of <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> not only by humans, but also by AIs. And it’s very nice to see that all the effort we’ve put into consistent language design, implementation and documentation over the years is now paying dividends in making Wolfram Language uniquely valuable as a tool for AIs—complementing their own intrinsic capabilities.<span id=\"more-66116\"></span></p>\n<p>But there’s another angle to AI as well. With our <a href=\"https://www.wolfram.com/notebook-assistant-llm-kit/\">Wolfram Notebook Assistant</a> launched last month we’re using AI technology (plus a lot more) to provide what amounts to a conversational interface to Wolfram Language. As I <a href=\"https://writings.stephenwolfram.com/2024/12/useful-to-the-point-of-being-revolutionary-introducing-wolfram-notebook-assistant/\">described when we released Wolfram Notebook Assistant</a>, it’s something extremely useful for experts and beginners alike, but ultimately I think its most important consequence will be to accelerate the ability to go from any field X to “computational X”—making use of the whole tower of technology we’ve built around Wolfram Language.</p>\n<p>So, what’s <a href=\"https://reference.wolfram.com/language/guide/\\\nSummaryOfNewFeaturesIn142.html\">new in 14.2</a>? Under the hood there are changes to make Wolfram Notebook Assistant more efficient and more streamlined. But there are also lots of visible extensions and enhancements to the user-visible parts of the Wolfram Language. In total there are 80 completely new functions—along with 177 functions that have been substantially updated.</p>\n<p>There are continuations of long-running R&D stories, like additional functionality for video, and additional capabilities around symbolic arrays. Then there are completely new areas of built-in functionality, like game theory. But the largest new development in Version 14.2 is around handling tabular data, and particularly, big tabular data. It’s a whole new subsystem for Wolfram Language, with powerful consequences throughout the system. We’ve been working on it for quite a few years, and we’re excited to be able to release it for the first time in Version 14.2.</p>\n<p>Talking of working on new functionality: starting more than seven years ago we pioneered the concept of open software design, <a href=\"https://livestreams.stephenwolfram.com/\">livestreaming our software design meetings</a>. And, for example, since the release of Version 14.1, we’ve done 43 software design livestreams, for a total of 46 hours (I’ve also done 73 hours of other livestreams in that time). Some of the functionality that’s now in Version 14.2 we started work on quite a few years ago. But we’ve been livestreaming long enough that pretty much anything that’s now in Version 14.2 we designed live and in public on a livestream at some time or another. It’s hard work doing software design (as you can tell if you watch the livestreams). But it’s always exciting to see the fruits of those efforts come to fruition in the system we’ve been progressively building for so long. And so, today, it’s a pleasure to be able to release Version 14.2 and to let everyone use the things we’ve been working so hard to build.</p>\n<h2 id=\"notebook-assistant-chat-inside-any-notebook\">Notebook Assistant Chat inside Any Notebook</h2>\n<p>Last month we released the <a href=\"https://writings.stephenwolfram.com/2024/12/useful-to-the-point-of-being-revolutionary-introducing-wolfram-notebook-assistant/\">Wolfram Notebook Assistant</a> to “turn words into computation”—and help experts and novices alike make broader and deeper use of <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> technology. In <a href=\"https://reference.wolfram.com/legacy/language/v14.1/\">Version 14.1</a> the primary way to use Notebook Assistant is through the separate “side chat” Notebook Assistant window. But in Version 14.2 “chat cells” have become a standard feature of any notebook available to anyone with a <a href=\"https://www.wolfram.com/notebook-assistant-llm-kit/\">Notebook Assistant subscription</a>.</p>\n<p>Just type <span class=\"kbd\"><kbd>‘</kbd></span> as the first character of any cell, and it’ll become a chat cell:</p>\n<p><img style=\"margin:6px;\" loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225chatimg1a.png' alt='Chat cell' title='Chat cell' width='620' height='42'/></p>\n<p>Now you can start chatting with the Notebook Assistant:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225chatimg2d2_copy.txt' data-c2c-type='text/html'> <img src='https://content.wolfram.com/sites/43/2025/01/sw012225chatimg2d.png' width='620' height='auto'/> </div>\n</p></div>\n<p>With the side chat you have a “separate channel” for communicating with the Notebook Assistant—that won’t, for example, be saved with your notebook. With chat cells, your chat becomes an integral part of the notebook.</p>\n<p>We actually <a href=\"https://writings.stephenwolfram.com/2023/06/introducing-chat-notebooks-integrating-llms-into-the-notebook-paradigm/\">first introduced Chat Notebooks</a> in the middle of 2023—just a few months after the <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">arrival of ChatGPT</a>. Chat Notebooks defined the interface, but at the time, the actual content of chat cells was purely from external LLMs. Now in Version 14.2, chat cells are not limited to separate Chat Notebooks, but are available in any notebook. And by default they make use of the full Notebook Assistant technology stack, which goes far beyond a raw LLM. In addition, once you have a <a href=\"https://www.wolfram.com/notebook-assistant-llm-kit/\">Notebook Assistant + LLM Kit subscription</a>, you can seamlessly use chat cells; no account with external LLM providers is needed. </p>\n<p>The chat cell functionality in Version 14.2 inherits all the features of Chat Notebooks. For example, typing <span class=\"kbd\"><kbd>~</kbd></span> in a new cell creates a chat break, that lets you start a “new conversation”. And when you use a chat cell, it’s able to see anything in your notebook up to the most recent chat break. (By the way, when you use Notebook Assistant through side chat it can also see what selection you’ve made in your “focus” notebook.)</p>\n<p>By default, chat cells are “talking” to the Notebook Assistant. But if you want, you can also use them to talk to external LLMs, just like in our original Chat Notebook—and there’s a convenient menu to set that up. Of course, if you’re using an external LLM, you don’t have all the technology that’s now in the Notebook Assistant, and unless you’re doing LLM research, you’ll typically find it much more useful and valuable to use chat cells in their default configuration—talking to the Notebook Assistant. </p>\n<h2 id=\"bring-us-your-gigabytes-introducing-tabular\">Bring Us Your Gigabytes! Introducing Tabular</h2>\n<p>Lists, associations, datasets. These are very flexible ways to represent structured collections of data in the <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>. But now in Version 14.2 there’s another: <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt>. <tt>Tabular</tt> provides a very streamlined and efficient way to handle tables of data laid out in rows and columns. And when we say “efficient” we mean that it can routinely juggle gigabytes of data or more, both in core and out of core. </p>\n<p>Let’s do an example. Let’s start off by importing some tabular data:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01202025gigabytesimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01202025gigabytesimg1.png' alt='' title='' width='734' height='303'> </div>\n</p></div>\n<p>This is data on trees in New York City, 683,788 of them, each with 45 properties (sometimes missing). <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt> introduces a variety of new ideas.

In our penguin data, we’ve got an individual row for each penguin of each species. But what if we want instead to aggregate all the penguins of a given species, for example computing their average body mass? Well, we can do this with <tt><a href=\"http://reference.wolfram.com/language/ref/AggregateRows.html\">AggregateRows</a></tt>. <tt>AggregateRows</tt> works like <tt><a href=\"http://reference.wolfram.com/language/ref/ConstructColumns.html\">ConstructColumns</a></tt> in the sense that you specify columns and their contents.

Yes, data is in digital form. But it’s not clean; it’s not computable. The Wolfram Language has long been a uniquely powerful tool for flexibly cleaning data (and, for example, for advancing through the <a href=\"https://writings.stephenwolfram.com/2017/04/launching-the-wolfram-data-repository-data-publishing-that-really-works/#the-data-curation-hierarchy\">ten levels of making data computable</a> that I defined some years ago). </p>\n<p>But now, in Version 14.2, with <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt>, we have a whole new collection of streamlined capabilities for cleaning data. Let’s start by importing some data “from the wild” (and, actually, this example is cleaner than many):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg1.png' alt='' title='' width='737' height='201'> </div>\n</p></div>\n<p>(By the way, if there was really crazy stuff in the file, we might have wanted to use the option <tt><a href=\"http://reference.wolfram.com/language/ref/MissingValuePattern.html\">MissingValuePattern</a></tt> to specify a pattern that would just immediately replace the crazy stuff with <tt><a href=\"http://reference.wolfram.com/language/ref/Missing.html\">Missing</a></tt><tt>[</tt>…<tt>]</tt>.)</p>\n<p>OK, but let’s start by surveying what came in here from our file, using <tt><a href=\"http://reference.wolfram.com/language/ref/TabularStructure.html\">TabularStructure</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg2.png' alt='' title='' width='592' height='242'> </div>\n</p></div>\n<p>We see that <tt><a href=\"http://reference.wolfram.com/language/ref/Import.html\">Import</a></tt> successfully managed to identify the basic type of data in most of the columns—though for example it can’t tell if numbers are just numbers or are representing quantities with units, etc. And it also identifies that some number of entries in some columns are “missing”. </p>\n<p>As a first step in data cleaning, let’s get rid of what seems like an irrelevant <tt>\"id\"</tt> column:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg3.png' alt='' title='' width='737' height='195'> </div>\n</p></div>\n<p>Next, we see that the elements in the first column are being identified as strings—but they’re really dates, and they should be combined with the times in the second column. We can do this with <tt><a href=\"http://reference.wolfram.com/language/ref/TransformColumns.html\">TransformColumns</a></tt>, removing what’s now an “extra column” by replacing it with <tt><a href=\"http://reference.wolfram.com/language/ref/Nothing.html\">Nothing</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg4a.png' alt='' title='' width='732' height='195'> </div>\n</p></div>\n<p>Looking at the various numerical columns, we see that they’re really quantities that should have units. But first, for convenience, let’s rename the last two columns:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg5.png' alt='' title='' width='674' height='147'> </div>\n</p></div>\n<p>Now let’s turn the numerical columns into columns of quantities with units, and, while we’re at it, also convert from °C to °F:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg6a.png' alt='' title='' width='684' height='283'> </div>\n</p></div>\n<p>Here’s how we can now plot the temperature as a function of time:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg7.png' alt='' title='' width='376' height='233'> </div>\n</p></div>\n<p>There’s a lot of wiggling there. And looking at the data we see that we’re getting temperature values from several different weather stations. This selects data from a single station:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg8.png' alt='' title='' width='613' height='252'> </div>\n</p></div>\n<p>What’s the break in the curve? If we just scroll to that part of the tabular we’ll see that it’s because of missing data:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg9a.png' alt='' title='' width='684' height='176'> </div>\n</p></div>\n<p>So what can we do about this? Well, there’s a powerful function <tt><a href=\"http://reference.wolfram.com/language/ref/TransformMissing.html\">TransformMissing</a></tt> that provides many options. Here we’re asking it to interpolate to fill in missing temperature values:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg10a.png' alt='' title='' width='684' height='290'> </div>\n</p></div>\n<p>And now there are no gaps, but, slightly mysteriously, the whole plot extends further:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg11.png' alt='' title='' width='402' height='250'> </div>\n</p></div>\n<p>The reason is that it’s interpolating even in cases where basically nothing was measured.

Let’s look at the histogram of pressure values for our data:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg14.png' alt='' title='' width='296' height='187'> </div>\n</p></div>\n<p>Oops.

We can remove such “anomalous” values by using <tt><a href=\"http://reference.wolfram.com/language/ref/TransformAnomalies.html\">TransformAnomalies</a></tt>. Here we’re telling it to just completely trim out any row where the pressure was “anomalous”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg15.png' alt='' title='' width='592' height='170'> </div>\n</p></div>\n<p>We can also get <tt><a href=\"http://reference.wolfram.com/language/ref/TransformAnomalies.html\">TransformAnomalies</a></tt> to try to “fix” the data. Here we’re just replacing any anomalous pressure by the previous pressure listed in the tabular:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg16.png' alt='' title='' width='622' height='214'> </div>\n</p></div>\n<p>You can also tell <tt><a href=\"http://reference.wolfram.com/language/ref/TransformAnomalies.html\">TransformAnomalies</a></tt> to “flag” any anomalous value and make it “missing”. But, if we’ve got missing values what then happens if we try to do computations on them? That’s where <tt><a href=\"http://reference.wolfram.com/language/ref/MissingFallback.html\">MissingFallback</a></tt> comes in. It’s fundamentally a very simple function—that just returns its first non-missing argument:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg17_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg17.png' alt='' title='' width='586' height='44'> </div>\n</p></div>\n<p>But even though it’s simple, it’s important in making it easy to handle missing values. So, for example, this computes a “northspeed”, falling back to 0 if data needed for the computation is missing:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningimg18_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw012225cleaningdataimg18a.png' alt='' title='' width='583' height='163'> </div>\n</p></div>\n<h2 id=\"the-structure-of-tabular\">The Structure of Tabular</h2>\n<p>We’ve said that a <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt> is “like” a list of associations. And, indeed, if you apply <tt><a href=\"http://reference.wolfram.com/language/ref/Normal.html\">Normal</a></tt> to it, that’s what you’ll get:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg1.png' alt='' title='' width='361' height='116'> </div>\n</p></div>\n<p>But internally <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt> is stored in a much more compact and efficient way. And it’s useful to know something about this, so you can manipulate <tt>Tabular</tt> objects without having to “take them apart” into things like lists and associations. Here’s our basic sample <tt>Tabular</tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg2.png' alt='' title='' width='280' height='86'> </div>\n</p></div>\n<p>What happens if we extract a row?

Let’s look at the example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureAimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureAimg10.png' alt='' title='' width='548' height='142'> </div>\n</p></div>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/TabularStructure.html\">TabularStructure</a></tt> gives us a summary of the internal structure here:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg11.png' alt='' title='' width='621' height='264'> </div>\n</p></div>\n<p>The first thing to notice is that everything is stated in terms of columns, reflecting the fact that <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt> is a fundamentally column-oriented construct. And part of what makes <tt>Tabular</tt> so efficient is then that within a column everything is uniform, in the sense that all the values are the same type of data. In addition, for things like quantities and dates, we factor the data so that what’s actually stored internally in the column is just a list of numbers, with a single copy of “metadata information” on how to interpret them.</p>\n<p>And, yes, all this has a big effect. Like here’s the size in bytes of our New York trees <tt>Tabular</tt> from above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureZimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg12.png' alt='' title='' width='214' height='48'> </div>\n</p></div>\n<p>But if we turn it into a list of associations using <tt><a href=\"http://reference.wolfram.com/language/ref/Normal.html\">Normal</a></tt>, the result is about 14x larger:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureZimg14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg13.png' alt='' title='' width='281' height='48'> </div>\n</p></div>\n<p>OK, but what are those “column types” in the tabular structure? <tt><a href=\"http://reference.wolfram.com/language/ref/ColumnTypes.html\">ColumnTypes</a></tt> gives a list of them:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg14.png' alt='' title='' width='585' height='68'> </div>\n</p></div>\n<p>These are low-level types of the kind used in the Wolfram Language compiler. And part of what knowing these does is that it immediately tells us what operations we can do on a particular column. And that’s useful both in low-level processing, and in things like knowing what kind of visualization might be possible.</p>\n<p>When <tt><a href=\"http://reference.wolfram.com/language/ref/Import.html\">Import</a></tt> imports data from something like a CSV file, it tries to infer what type each column is. But sometimes (as we mentioned above) you’ll want to “cast” a column to a different type, specifying the “destination type” using Wolfram Language type description. So, for example, this casts column “b” to a 32-bit real number, and column “c” to units of meters:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureAimg15.png' alt='' title='' width='602' height='172'> </div>\n</p></div>\n<p>By the way, when a <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt> is displayed in a notebook, the column headers indicate the types of data in the corresponding columns. So in this case, there’s a little <img loading='lazy' style=\"margin-bottom: -4px\" src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg16.png' width='20' height='20'/> in the first column to indicate that it contains strings. Numbers and dates basically just “show what they are”. Quantities have their units indicated. And general symbolic expressions (like column “f” here) are indicated with <img loading='lazy' style=\"margin-bottom: -4px\" src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg17.png' width='20' height='20'/>. (If you hover over a column header, it gives you more detail about the types.)</p>\n<p>The next thing to discuss is missing data. <tt>Tabular</tt> always treats columns as being of a uniform type, but keeps an overall map of where values are missing.

Well, then you can designate all those columns as key columns:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg31_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg31.png' alt='' title='' width='484' height='162'> </div>\n</p></div>\n<p>And once you’ve done that, you can reference a row by giving the values in all the key columns:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg32_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025structureimg32.png' alt='' title='' width='283' height='43'> </div>\n</p></div>\n<h2 id=\"tabular-everywhere\">Tabular Everywhere</h2>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt> provides an important new way to represent structured data in the Wolfram Language.

But the more we’ve made it easy to do, the more we can see new places where we can polish the language further. And in Version 14.2—like every version before it—we’ve added a number of “language tune-ups”. </p>\n<p>A simple one—whose utility becomes particularly clear with <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt>—is <tt><a href=\"http://reference.wolfram.com/language/ref/Discard.html\">Discard</a></tt>.

Normally, <tt>Select</tt> just gives a list of the elements it selects. But in Version 14.2 you can specify other results. Here we’re asking for the “index” (i.e. position) of the elements that <tt><a href=\"http://reference.wolfram.com/language/ref/NumberQ.html\">NumberQ</a></tt> is selecting:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01162025languageAimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01162025languageimg2.png' alt='' title='' width='378' height='44'> </div>\n</p></div>\n<p>Something that can be helpful in dealing with very large amounts of data is getting a bit vector data structure from <tt><a href=\"http://reference.wolfram.com/language/ref/Select.html\">Select</a></tt> (and <tt><a href=\"http://reference.wolfram.com/language/ref/Discard.html\">Discard</a></tt>), that provides a bit mask of which elements are selected or not: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01162025languageAimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01162025languageimg3.png' alt='' title='' width='397' height='73'> </div>\n</p></div>\n<p>By the way, here’s how you can ask for multiple results from <tt><a href=\"http://reference.wolfram.com/language/ref/Select.html\">Select</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/Discard.html\">Discard</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01162025languageAimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01162025languageimg4.png' alt='' title='' width='490' height='44'> </div>\n</p></div>\n<p>In talking about <tt><a href=\"http://reference.wolfram.com/language/ref/Tabular.html\">Tabular</a></tt> we already mentioned <tt><a href=\"http://reference.wolfram.com/language/ref/MissingFallback.html\">MissingFallback</a></tt>. Another function related to code robustification and error handling is the new function <tt><a href=\"http://reference.wolfram.com/language/ref/Failsafe.html\">Failsafe</a></tt>. Let’s say you’ve got a list which contains some “failed” elements. If you map a function <tt>f</tt> over that list, it’ll apply itself to the failure elements just as to everything else:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01162025languageAimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01162025languageimg5.png' alt='' title='' width='385' height='45'> </div>\n</p></div>\n<p>But quite possibly <tt>f</tt> wasn’t set up to deal with these kinds of failure inputs. And that’s where <tt><a href=\"http://reference.wolfram.com/language/ref/Failsafe.html\">Failsafe</a></tt> comes in. Because <tt>Failsafe</tt>[<tt>f][</tt><em>x</em><tt>]</tt> is defined to give <tt>f[</tt><em>x</em><tt>]</tt> if <em>x</em> is not a failure, and to just return the failure if it is. So now we can map <tt>f</tt> across our list with impunity, knowing it’ll never be fed failure input:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01162025languageAimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01162025languageimg6.png' alt='' title='' width='372' height='45'> </div>\n</p></div>\n<p>Talking of tricky error cases, another new function in Version 14.2 is <tt><a href=\"http://reference.wolfram.com/language/ref/HoldCompleteForm.html\">HoldCompleteForm</a></tt>. <tt><a href=\"http://reference.wolfram.com/language/ref/HoldForm.html\">HoldForm</a></tt> lets you display an expression without doing ordinary evaluation of the expression.

At that time, these functions needed access to external LLM services. But with the release last month of <a href=\"https://writings.stephenwolfram.com/2024/12/useful-to-the-point-of-being-revolutionary-introducing-wolfram-notebook-assistant/\">LLM Kit (along with Wolfram Notebook Assistant)</a> we’ve made these functions seamlessly available for everyone with a <a href=\"https://www.wolfram.com/notebook-assistant-llm-kit/\">Notebook Assistant + LLM Kit subscription</a>. Once you have your subscription, you can use programmatic LLM functions anywhere and everywhere in Version 14.2 without any further set up. </p>\n<p>There are also two new functions: <tt><a href=\"http://reference.wolfram.com/language/ref/LLMSynthesizeSubmit.html\">LLMSynthesizeSubmit</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/ChatSubmit.html\">ChatSubmit</a></tt>. Both are concerned with letting you get incremental results from LLMs (and, yes, that’s important, at least for now, because LLMs can be quite slow).

The parallel computation can happen on multiple cores on a single machine, or across many machines on a network. (And, for example, in my own current setup I have 7 machines right now with a total of 204 cores.)</p>\n<p>In the past few years, partly responding to the increasing number of cores typically available on individual machines, we’ve been progressively streamlining the way that parallel computation is provisioned. And in Version 14.2 we’ve, yes, parallelized the provisioning of parallel computation. Which means, for example, that my 7 machines all start their parallel kernels in parallel—so that the whole process is now finished in a matter of seconds, rather than potentially taking minutes, as it did before:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01212025parallelimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01212025parallelimg1.png' alt='' title='' width='166' height='14'> </div>\n</p></div>\n<p><img src='https://content.wolfram.com/sites/43/2025/01/sw01212025parallelimg2.png' alt='' title='' width='410' height='71'/></p>\n<p>Another new feature for parallel computation in Version 14.2 is the ability to automatically parallelize across multiple variables in <tt><a href=\"http://reference.wolfram.com/language/ref/ParallelTable.html\">ParallelTable</a></tt>. <tt>ParallelTable</tt> has always had a variety of algorithms for optimizing the way it splits up computations for different kernels.

And, yes, there has been lots of game theory done with the <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>, and lots of packages written for particular aspects of it. But in Version 14.2 we’re finally introducing built-in system functions for doing game theory (both matrix games and tree games).</p>\n<p>Here’s how we specify a (zero-sum) 2-player matrix game:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01162025gameimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01162025gameimg1.png' alt='' title='' width='347' height='75'> </div>\n</p></div>\n<p>This defines payoffs when each player takes each action.

In other words, what action should each player take, with what probability, to maximize their average payoff over many instances of the game? (It’s assumed that in each instance the players simultaneously and independently choose their actions.) A “solution” that maximizes expected payoffs for all players is called a Nash equilibrium. (As a small footnote to history, <a href=\"https://www.wolframalpha.com/input?i=john+nash\">John Nash</a> was a long-time user of Mathematica and what’s now the Wolfram Language—though many years after he came up with the concept of Nash equilibrium.)

But now, in typical Wolfram Language fashion, it’s all computable and extensible—so you can study more realistic games, and quickly do lots of examples to build intuition. </p>\n<p>We’ve so far concentrated on “classic game theory”, notably with the feature (relevant to many current applications) that all action nodes are the result of a different sequence of actions. However, games like tic-tac-toe (that I happened to <a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-multicomputational-systems/\">recently study using multiway graphs</a>) can be simplified by merging equivalent action nodes. Multiple sequences of actions may lead to the same game of tic-tac-toe, as is often the case for iterated games. These graph structures don’t fit into the kind of classic game theory trees we’ve introduced in Version 14.2—though (as my own efforts I think demonstrate) they’re uniquely amenable to analysis with the Wolfram Language.</p>\n<h2 id=\"computing-the-syzygies-and-other-advances-in-astronomy\">Computing the Syzygies, and Other Advances in Astronomy</h2>\n<p>There are lots of “coincidences” in astronomy—situations where things line up in a particular way. <a href=\"https://writings.stephenwolfram.com/2024/03/computing-the-eclipse-astronomy-in-the-wolfram-language/\">Eclipses are one example</a>.

Of course it helped that we could rely on all the other capabilities of the Wolfram Language—and what we’ve been able to produce is immeasurably more valuable because of its synergy with the rest of the system. But over the years, with great effort, we’ve been steadily building up symbolic PDE modeling capabilities across all the standard domains. And at this point I think it’s fair to say that we can handle—at an industrial scale—a large part of the PDE modeling that arises in real-world situations. </p>\n<p>But there are always more cases for which we can build in capabilities, and in Version 14.2 we’re adding built-in modeling primitives for static and quasistatic magnetic fields. So, for example, here’s how we can now model an hourglass-shaped magnet. This defines boundary conditions—then solves the equations for the magnetic scalar potential:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01152025pdesimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01162025pdesAimg1.png' alt='' title='' width='583' height='315'> </div>\n</p></div>\n<p>We can then take that result, and, for example, immediately plot the magnetic field lines it implies:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01152025pdesimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01152025pdesimg2.png' alt='' title='' width='673' height='434'> </div>\n</p></div>\n<p>Version 14.2 also adds the primitives to deal with slowly varying electric currents, and the magnetic fields they generate. All of this immediately integrates with our other modeling domains like heat transfer, fluid dynamics, acoustics, etc. </p>\n<p><a href=\"https://reference.wolfram.com/language/PDEModels/tutorial/PDEModelsOverview.html\">There’s much to say about PDE modeling and its applications</a>, and in Version 14.2 we’ve added more than 200 pages of additional textbook-style documentation about PDE modeling, including some research-level examples.</p>\n<h2 id=\"new-features-in-graphics-geometry--graphs\">New Features in Graphics, Geometry & Graphs</h2>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/Graphics.html\">Graphics</a></tt> has always been a strong area for the <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>, and over the past decade we’ve also built up very strong computational geometry capabilities.

In Version 14.2 there are several notable pieces of polish that have been added. One concerns <a href=\"https://reference.wolfram.com/language/workflow/AutocompleteSymbolsWhenTyping.html.en\">autocompletion</a> for option values. </p>\n<p>We’ve long shown completions for options that have a discrete collection of definite common settings (such as <tt><a href=\"http://reference.wolfram.com/language/ref/All.html\">All</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/Automatic.html\">Automatic</a></tt>, etc.). In Version 14.2 we’re adding “template completions” that give the structure of settings, and then let you tab through to fill in particular values. In all these years, one of the places I pretty much always find myself going to in the documentation is the settings for <tt><a href=\"http://reference.wolfram.com/language/ref/FrameLabel.html\">FrameLabel</a></tt>. But now autocompletion immediately shows me the structure of these settings:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/01/sw01152025interfaceimg1.png' alt='Interface settings autocompletion' title='Interface settings autocompletion' width='427' height='88'/></p>\n<p>Also in autocompletion, we’ve added the capability to autocomplete context names, context aliases, and symbols that include contexts. And in all cases, the autocompletion is “fuzzy” in the sense that it’ll trigger not only on characters at the beginning of a name but on ones anywhere in the name—which means that you can just type characters in the name of a symbol, and relevant contexts will appear as autocompletions.</p>\n<p>Another small convenience added in Version 14.2 is the ability to drag images from one notebook to any other notebook, or, for that matter, to any other application that can accept dragged images. It’s been possible to drag images from other applications into notebooks, but now you can do it the other way too.</p>\n<p>Something else that’s for now specific to macOS is enhanced support for icon preview (as well as Quick Look). So now if you have a folder full of notebooks and you select <span class=\"promptformatted\">Icon</span> view, you’ll see a little representation of each notebook as an icon of its content:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/01/sw01152025interfaceimg2.png' alt='Notebook icon preview' title='Notebook icon preview' width='522' height='85'/></p>\n<p>Under the hood in Version 14.2 there are also some infrastructural developments that will enable significant new features in subsequent versions. Some of these involve generalized support for dark mode. (Yes, one might initially imagine that dark mode would somehow be trivial, but when you start thinking about all the graphics and interface elements that involve colors, it’s clear it’s not. Though, for example, after significant effort we did recently release dark mode for <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>.)</p>\n<p>So, for example, in Version 14.2 you’ll find the new symbol <tt><a href=\"http://reference.wolfram.com/language/ref/LightDarkSwitched.html\">LightDarkSwitched</a></tt>, which is part of the mechanism for specifying styles that will automatically switch for light and dark modes. And, yes, there is a style option <tt><a href=\"http://reference.wolfram.com/language/ref/LightDark.html\">LightDark</a></tt> that will switch modes for notebooks—and which is at least experimentally supported.</p>\n<p>Related to light/dark mode is also the notion of theme colors: colors that are defined symbolically and can be switched together. And, yes, there’s an experimental symbol <tt><a href=\"http://reference.wolfram.com/language/ref/ThemeColor.html\">ThemeColor</a></tt> related to these. But the full deployment of this whole mechanism won’t be there until the next version.</p>\n<h2 id=\"the-beginnings-of-going-native-on-gpus\">The Beginnings of Going Native on GPUs</h2>\n<p>Many important pieces of functionality inside the Wolfram Language automatically make use of GPUs when they are available. And already 15 years ago we introduced primitives for low-level GPU programming. But in Version 14.2 we’re beginning the process of <a href=\"https://reference.wolfram.com/language/guide/GPUComputing.html.en\">making GPU capabilities more readily available</a> as a way to optimize general Wolfram Language usage. The key new construct is <tt><a href=\"http://reference.wolfram.com/language/ref/GPUArray.html\">GPUArray</a></tt>, which represents an array of data that will (if possible) be stored so as to be immediately and directly accessible to your GPU. (On some systems, it will be stored in separate “GPU memory”; on others, such as modern Macs, it will be stored in shared memory in such a way as to be directly accessible by the GPU.)</p>\n<p>In Version 14.2 we’re supporting an initial set of operations that can be performed directly on GPU arrays. The operations available vary slightly from one type of GPU to another. Over time, we expect to use or create many additional GPU libraries that will extend the set of operations that can be performed on GPU arrays. </p>\n<p>Here is a random ten-million-element vector stored as a GPU array: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg1.png' alt='' title='' width='399' height='97'> </div>\n</p></div>\n<p>The GPU on the Mac on which I am writing this supports the necessary operations to do this purely in its GPU, giving back a <tt><a href=\"http://reference.wolfram.com/language/ref/GPUArray.html\">GPUArray</a></tt> result:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg2.png' alt='' title='' width='299' height='97'> </div>\n</p></div>\n<p>Here’s the timing:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg3.png' alt='' title='' width='308' height='44'> </div>\n</p></div>\n<p>And here’s the corresponding ordinary (CPU) result:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01152025nativeimg4.png' alt='' title='' width='664' height='44'> </div>\n</p></div>\n<p>In this case, the <tt><a href=\"http://reference.wolfram.com/language/ref/GPUArray.html\">GPUArray</a></tt> result is about a factor of 2 faster. What factor you get will vary with the operations you’re doing, and the particular hardware you’re using. So far, the largest factors I’ve seen are around 10x. But as we build more GPU libraries, I expect this to increase—particularly when what you’re doing involves a lot of compute “inside the GPU”, and not too much memory access. </p>\n<p>By the way, if you sprinkle <tt>GPUArray</tt> in your code it’ll normally never affect the results you get—because operations always default to running on your CPU if they’re not supported on your GPU. (Usually <tt>GPUArray</tt> will make things faster, but if there are too many “GPU misses” then all the “attempts to move data” may actually slow things down.) It’s worth realizing, though, that GPU computation is still not at all well standardized or uniform.

(I also showed that what I found was <a href=\"https://www.wolframscience.com/nks/notes-12-9--searching-for-logic-axioms/\">the simplest possible</a>.) </p>\n<p>It was an interesting result—that gave new intuition about just how simple the foundations of things can be, and for example helped inspire my efforts to find a <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">simple underlying theory of physics</a>. </p>\n<p>But how did I get the result? Well, I used automated theorem proving (specifically, what’s now <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> in <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>). Automated theorem proving is something that’s <a href=\"https://www.wolframscience.com/nks/notes-12-9--automated-theorem-proving/\">been around since at least the 1950s</a>, and its core methods haven’t changed in a long time. But in the rare cases it’s been used in mathematics it’s typically been to confirm things that were already believed to be true. And in fact, to my knowledge, my Boolean algebra axiom is actually the only truly unexpected result that’s ever been found for the first time using automated theorem proving.<span id=\"more-65170\"></span></p>\n<p>But, OK, so we know it’s true. And that’s interesting. But what about the proof? Does the proof, for example, show us why the result is true? Well, actually, in a quarter of a century, nobody (including me) has ever made much headway at all in understanding the proof (which, at least in the form we currently know it, is long and complicated). So is that basically inevitable—say as a consequence of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>? Or is there some way—perhaps <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">using modern AI</a>—to “humanize” the proof to a point where one can understand it?</p>\n<p>It is, I think, an interesting challenge—that gets at the heart of what one can (and can’t) expect to achieve with formalized mathematics. In what follows, I’ll discuss what I’ve been able to figure out—and how it relates to foundational questions about what mathematics is and how it can be done. And while I think I’ve been able to clarify some of the issues, the core problem is still out there—and I’d like to issue it here as a challenge:</p>\n<p style=\"font-size: 1.1rem;background: #e5f2f8b5;padding: 10px 20px;border: 2px solid #91c5dcfa;max-width:620px;margin: 0px 0px 15px 0px;line-height: 1.6;font-family: 'Source Serif 4',Georgia,serif;color: #383838;font-weight:600;font-optical-sizing:auto;\"><span style=\"color: #555;font-weight: 700;\">Challenge:</span> Understand the proof of the Theorem</p>\n<p>What do I mean by “understand”? Inevitably, “understand” has to be defined in human terms. Something like “so a human can follow and reproduce it”—and, with luck, feel like saying “aha!” at some point, the kind of way they might on hearing a proof of the Pythagorean theorem (or, in logic, something like de Morgan’s law <tt><a href=\"http://reference.wolfram.com/language/ref/Not.html\">Not</a></tt>[<tt><a href=\"http://reference.wolfram.com/language/ref/And.html\">And</a></tt>[<em>p</em>, <em>q</em>]]<span class=\"special-character\"></span><tt><a href=\"http://reference.wolfram.com/language/ref/Or.html\">Or</a></tt>[<tt><a href=\"http://reference.wolfram.com/language/ref/Not.html\">Not</a></tt>[<em>p</em>], <tt><a href=\"http://reference.wolfram.com/language/ref/Not.html\">Not</a></tt>[<em>q</em>]]). </p>\n<p>It should be said that it’s certainly not clear that such an understanding would ever be possible. After all, as we’ll discuss, it’s a basic metamathematical fact that out of all possible theorems almost none have short proofs, at least in terms of any particular way of stating the proofs. But what about an “interesting theorem” like the one we’re considering here? Maybe that’s different. Or maybe, at least, there’s some way of building out a “higher-level mathematical narrative” for a theorem like this that will take one through the proof in human-accessible steps.</p>\n<p>In principle one could always imagine a somewhat bizarre scenario in which people would just rote learn chunks of the proof, perhaps giving each chunk some name (a bit like how people learned bArbArA and cElArEnt syllogisms in the Middle Ages). And in terms of these chunks there’d presumably then be a “human way” to talk about the proof. But learning the chunks—other than as some kind of recreational or devotional activity—doesn’t seem to make much sense unless there’s metamathematical structure that somehow connects the chunks to “general concepts” that are widely useful elsewhere. </p>\n<p>But of course it’s still conceivable that there might be a “big theory” that would lead us to the theorem in an “understandable way”. And that could be a traditional mathematical theory, built up with precise, if potentially very abstract, constructs. But what about something more like a theory in natural science? In which we might treat our automatically generated proof as an object for empirical study—exploring its characteristics, trying to get intuition about it, and ultimately trying to deduce the analog of “natural laws” that give us a “human-level” way of understanding it. </p>\n<p>Of course, for many purposes it doesn’t really matter why the theorem is true. All that matters is that it is true, and that one can deduce things on the basis of it. But as one thinks about the future of mathematics, and the future of doing mathematics, it’s interesting to explore to what extent it might or might not ultimately be possible to understand in a human-accessible way the kind of seemingly alien result that the theorem represents. </p>\n<h2 id=\"the-proof-as-we-know-it\">The Proof as We Know It</h2>\n<p>I first presented a version of the proof on <a href=\"https://www.wolframscience.com/nks/p810--implications-for-mathematics-and-its-foundations/\">two pages</a> of my 2002 book <em><a href=\"https://www.wolframscience.com/nks/\">A New Kind of Science</a></em>, printing it in 4-point type to make it fit: </p>\n<p><a href=\"https://files.wolframcdn.com/pub/www.wolframscience.com/nks/nks-ch12-sec9.pdf\" ><img src='https://content.wolfram.com/sites/43/2025/01/sw01082025proofimg1.png' alt='Axiom proof' title='Axiom proof' width='619' height='373'/></a></p>\n<p>Today, generating a very similar proof is a one-liner in Wolfram Language (as we’ll discuss below, the · dot here can be thought of as representing the <tt><a href=\"http://reference.wolfram.com/language/ref/Nand.html\">Nand</a></tt> operation):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025FEPimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025proofimg2.png' alt='' title='' width='455' height='100'> </div>\n</p></div>\n<p>The proof involves 307 (mostly rather elaborate) steps.

Well, from the symbolic representation of the proof in the Wolfram Language we can immediately generate a “proof function” that in effect contains executable versions of all the lemmas—implemented using simple structural operations:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025proofCLOUDXimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025proofCLOUDAimg11A.png' alt='' title='' width='551' height='453'> </div>\n</p></div>\n<p>And when you run this function, it applies all these lemmas and checks that the result comes out right:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025proofCLOUDZimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025proofimg14.png' alt='' title='' width='259' height='43'> </div>\n</p></div>\n<p>And, yes, this is basically what one would do in a proof assistant system (like <a href=\"https://lean-lang.org/\" target=\"_blank\" rel=\"noopener\">Lean</a> or <a href=\"https://us.metamath.org/index.html\" target=\"_blank\" rel=\"noopener\">Metamath</a>)—except that here the steps in the proof were generated purely automatically, without any human guidance (or effort). And, by the way, the fact that we can readily translate our symbolic proof representation into a function that we can run provides an operational manifestation of the equivalence between proofs and programs. </p>\n<p>But let’s look back at our lemma-interdependence “proof graph”. One notable feature is that we see several nodes with high out-degree—corresponding to what we can think of as “pivotal lemmas” from which many other lemmas end up directly being proved. So here’s a list of the “most pivotal” lemmas in our proof:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01102025outdegreeimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01102025outdegreeimg1.png' alt='' title='' width='330' height='178'> </div>\n</p></div>\n<p>Or, more graphically, here are the results for all lemmas that occur:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01102025outdegreeimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01102025outdegreeimg2.png' alt='' title='' width='341' height='237'> </div>\n</p></div>\n<p>So what are the “pivotal lemmas”? <em>a</em> · <em>b</em> = <em>b</em> · <em>a</em> we readily recognize as commutativity. But the others—despite their comparative simplicity—don’t seem to correspond to things that have specifically shown up before in the mathematical literature (or, as we’ll <a href=\"https://writings.stephenwolfram.com/2025/01/who-can-understand-the-proof-a-window-on-formalized-mathematics/#llms-to-the-rescue\">discuss later</a>, that’s at least what the current generation of LLMs tell us).</p>\n<p>But looking at our proof graph something we can conclude is that a large fraction of the “heavy lifting” needed for the whole proof has already happened by the time we can prove <em>a</em> · <em>b</em> = <em>b</em> · <em>a</em>.

Or in effect to find a suitable “path” through the multiway graph of all possible substitutions etc. that can be made. </p>\n<p>So, for example, in the particular case we’re considering here, this is the graph that represents all possible transformations that can occur through a single substitution event:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg10.png' alt='' title='' width='582' height='285'> </div>\n</p></div>\n<p>The particular transformation (or “path”) we’ve used to prove <em>a</em> · <em>a</em> = <em>a</em> · ((<em>a</em> · <em>a</em>) · <em>a</em>) is highlighted. But as we can see, there are many other possible lemmas that can be generated, or in other words that can be proved from the two lemmas we’ve given as input. Put another way, we can think of our input lemmas as implying or entailing all the other lemmas shown here. And, by analogy to the concept of a light cone in physics, we can view the collection of everything entailed by given lemmas or given events as the (future) “<a href=\"https://www.wolframscience.com/metamathematics/metamathematical-space/#p-28\">entailment cone</a>” of those lemmas or events. A proof that reaches a particular lemma is then effectively a path in this entailment cone—analogous in physics to a world line that reaches a particular spacetime point.</p>\n<p>If we continue building out the entailment cone from our original lemmas, then after two (substitution) events we get:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg11.png' alt='' title='' width='701' height='454'> </div>\n</p></div>\n<p>There are 21 lemmas generated here. But it turns out that beyond the lemma we already discussed there are only three (highlighted here) that appear in the proof we are studying here:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg12.png' alt='' title='' width='281' height='60'> </div>\n</p></div>\n<p>And indeed the <a href=\"https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/#the-mechanics-of-proof\">main algorithmic challenge of theorem proving</a> is to figure out which lemmas to generate in order to get a path to the theorem one’s trying to prove. And, yes, as we’ll discuss later, there are typically many paths that will work, and different algorithms will yield different paths and therefore different proofs.</p>\n<p>But, OK, seeing how new lemmas can be derived from old by substitution is already quite complicated. But actually there’s something even more complicated we need to discuss: deriving lemmas not only by substitution but also by what we’ve called <a href=\"https://www.wolframscience.com/metamathematics/beyond-substitution-cosubstitution-and-bisubstitution/\">bisubstitution</a>. </p>\n<p>We can think of both substitution and bisubstitution as turning one lemma X == Y into a transformation rule (either X <img style=\"margin-bottom: -1px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow2.png\" width='15' height='11' > Y or Y <img style=\"margin-bottom: -1px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow2.png\" width='15' height='11' > X), and then applying this rule to another lemma, to derive a new lemma. In ordinary substitution, the left-hand side of the rule directly matches (in a Wolfram Language pattern-matching sense) a subexpression in the lemma we’re transforming. But the key point is that all the variables that appear in both our lemmas are really “pattern variables” (<tt>x_</tt> etc. in Wolfram Language). So that means there’s another way that one lemma can transform another, in which in effect replacements are made not only in the lemma being transformed, but also in the lemma that’s doing the transforming. </p>\n<p>The net effect, though, is still to take two lemmas and derive another, as in:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025KDCLOUDimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025KDCLOUDimg3.png' alt='' title='' width='414' height='130'> </div>\n</p></div>\n<p>But in tracing through the details of our proof, we need to distinguish “substitution events” (shown yellowish) from “bisubstitution” ones (shown reddish).

So why is that? Essentially it seems to be because bisubstitution events tend to produce larger lemmas, and ordinary substitution events tend to produce smaller ones—as we can see if we plot input and output lemma sizes for all events in the proof:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg37_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg37.png' alt='' title='' width='451' height='479'> </div>\n</p></div>\n<p>So in effect what seems to be happening is that the proof first has to “spread out in <a href=\"https://www.wolframscience.com/metamathematics/metamathematical-space/\">metamathematical space</a>”, using bisubstitution to generate large lemmas “far out in metamathematical space”. Then later the proof has to “corral things back in”, using ordinary substitution to generate smaller lemmas. And for example, at the very end, it’s a substitution event that yields the final theorem we’re trying to prove:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg38_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg38.png' alt='' title='' width='277' height='100'> </div>\n</p></div>\n<p>And earlier in the graph, there’s a similar “collapse” to a small (and rather pivotal) lemma:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg39_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg39.png' alt='' title='' width='406' height='120'> </div>\n</p></div>\n<p>As the plot above indicates, ordinary substitution can lead to large lemmas, and indeed bisubstitution can also lead to smaller ones, as in</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg40_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg40.png' alt='' title='' width='367' height='87'> </div>\n</p></div>\n<p>or slightly more dramatically:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg41_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg41.png' alt='' title='' width='630' height='140'> </div>\n</p></div>\n<p>But, OK, so this is some of what’s going on at a “machine-code” level inside the proof we have. Of course, given our axiom and the operations of substitution and bisubstitution there are inevitably a huge number of different possible proofs that could be given. The particular proof we’re considering is what the Wolfram Language <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> gives. (In the Appendix, we’ll also look at results from some other automated theorem proving systems.

But fundamentally what they’re doing is to try constructing certain lemmas, then to find sequences of lemmas that eventually form a “path” to what we’re trying to prove. And as some indication of what’s involved in this, here’s a plot of the number of “candidate lemmas” that are being maintained as possible when different lemmas in the proof are generated:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025machineCLOUDimg42_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025machineimg42.png' alt='' title='' width='354' height='145'> </div>\n</p></div>\n<p>And, yes, for a while there’s roughly exponential growth, leveling off at just over a million when we get to the “pulling everything together” stage of the proof.</p>\n<h2 id=\"unrolling-the-proof\">Unrolling the Proof</h2>\n<p>In what we’ve done so far, we’ve viewed our proof as working by starting from an axiom, then <a href=\"https://www.wolframscience.com/nks/notes-12-9--proof-structures/\">progressively building up lemmas</a>, until eventually we get to the theorem we want. But there’s an alternative view that’s in some ways useful in getting a more direct, “mechanical” intuition about what’s going on in the proof.</p>\n<p>Let’s say we’re trying to prove that our axiom implies that <em>p</em> · <em>q</em> = <em>q</em> · <em>p</em>. Well, then there must be some way to start from the expression <em>p</em> · <em>q</em> and just keep on judiciously applying the axiom until eventually we get to the expression <em>q</em> · <em>p</em>. And, yes, the number of axiom application steps required might be very large. But ultimately, if it’s true that the axiom implies <em>p</em> · <em>q</em> = <em>q</em> · <em>p</em> there must be a path that gets from <em>p</em> · <em>q</em> to <em>q</em> · <em>p</em>.</p>\n<p>But before considering the case of our full proof, let’s start with something simpler.

But if one does this, it inevitably involves repeating lots of work. Being able to use intermediate lemmas in effect lets one “share common subparts” in the proof. So that one ends up with just 104 “rule applications”, rather than 83314. Not that it’s easy to understand those 104 steps…</p>\n<h2 id=\"is-there-a-better-notation\">Is There a Better Notation?</h2>\n<p> Looking at our proof—either in its original “lemma” form, or in its “unrolled” form—the most striking aspect of it is how complicated (and incomprehensible) it seems to be. But one might wonder whether much of that complexity is just the result of not “using the right notation”. In the end, we’ve got a huge number of expressions written in terms of · operations that we can interpret as <tt><a href=\"http://reference.wolfram.com/language/ref/Nand.html\">Nand</a></tt> (or <tt><a href=\"http://reference.wolfram.com/language/ref/Nor.html\">Nor</a></tt>). And maybe it’s a little like seeing the operation of a microprocessor down at the level of individual gates implementing <tt>Nand</tt>s or <tt>Nor</tt>s. And might there perhaps be an analog of a higher-level representation—with higher-level operations (even like arithmetic) that are more accessible to us humans?</p>\n<p>It perhaps doesn’t help that <tt>Nand</tt> itself is a rather non-human construct. For example, not a single natural human language seems to have a word for <tt>Nand</tt>. But there are combinations of <tt>Nand</tt>s that have more <a href=\"https://www.wolframscience.com/nks/p807--implications-for-mathematics-and-its-foundations/\">familiar interpretations</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025notationimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025notationimg1.png' alt='' title='' width='228' height='127'> </div>\n</p></div>\n<p>But what combinations actually occur in our proof? Here are the most common subexpressions that appear in lemmas in the proof:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092925NLCLOUDimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092925NLCLOUDimg12.png' alt='' title='' width='290' height='316'> </div>\n</p></div>\n<p>And, yes, we could give the most common of these special names. But it wouldn’t really help in “compressing” the proof—or making it easier to understand.</p>\n<p>What about “upgrading” our “laws of inference”, i.e. the way that we can derive new lemmas from old? Perhaps instead of substitution and bisubstitution, which both take two lemmas and produce one more, we could set up more elaborate “tactics” that for example take in more input lemmas. We’ve seen that if we completely unroll the proof, it gets much longer. So perhaps there is a “higher-order” setup that for example dramatically shortens the proof. </p>\n<p>One way one might identify this is by seeing commonly repeating structures in the subgraphs that lead to lemmas. But in fact these subgraphs are quite diverse:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025notationCLOUDAimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025notationimg3.png' alt='' title='' width='589' height='130'> </div>\n</p></div>\n<h2 id=\"what-are-the-popular-lemmas\">What Are the Popular Lemmas?</h2>\n<p>A typical feature of human-written mathematical proofs is that they’re “anchored” by famous theorems or lemmas. They may have fiddly technical pieces. But usually there’s a backbone of “theorems people know”. </p>\n<p>We have the impression that the proof we’re discussing here “spends most of its time wandering around the wilds of metamathematical space”. But perhaps it visits waypoints that are somehow recognizable, or at least should be. Or in other words, perhaps out in the metamathematical space of lemmas there are ones that are somehow sufficiently popular that they’re worth giving names to, and learning—and can then be used as “reference points” in terms of which our proof becomes simpler and more human accessible.</p>\n<p>It’s a story very much like what happens with human language. There are things out there in the world, but when there’s a certain category of them that are somehow common or important enough, we make a word for them in our language, which we can then use to “compactly” refer to them. (It’s again the same story when it comes to computational language, and in particular the Wolfram Language, except that in that case it’s been my personal responsibility to come up with the appropriate definitions and names for functions to represent “common lumps of computation”.) </p>\n<p>But, OK, so what are the “popular lemmas” of <tt><a href=\"http://reference.wolfram.com/language/ref/Nand.html\">Nand</a></tt> proofs? One way to explore this is to enumerate statements that are “true about <tt>Nand</tt>”—then to look at proofs of these statements (say found with <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> from our axiom) and see what lemmas show up frequently in them. </p>\n<p><a href=\"https://www.wolframscience.com/nks/p818--implications-for-mathematics-and-its-foundations/\">Enumerating statements “true about <tt>Nand</tt>”</a>, starting from the smallest, we get</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg1.png' alt='' title='' width='598' height='222'> </div>\n</p></div>\n<p>where we have highlighted statements from this list that appear as lemmas in our proof.</p>\n<p>Proving each of these statements from our original axiom, here are the <a href=\"https://www.wolframscience.com/nks/notes-12-9--proof-lengths-in-logic/\">lengths of proofs we find</a> (for all 1341 distinct theorems with up to <tt><a href=\"http://reference.wolfram.com/language/ref/LeafCount.html\">LeafCount</a></tt> 4 on each side):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg2.png' alt='' title='' width='471' height='204'> </div>\n</p></div>\n<p>A histogram shows that it’s basically a bimodal distribution</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg3.png' alt='' title='' width='359' height='134'> </div>\n</p></div>\n<p>with the smallest “long-proof” theorem being:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg4.png' alt='' title='' width='173' height='14'> </div>\n</p></div>\n<p>In aggregate, all these proofs use about 200,000 lemmas.

So what are these lemmas? Here’s a plot of the usage frequency of lemmas against their size—with the “common ones” populating the top line: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg7.png' alt='' title='' width='438' height='192'> </div>\n</p></div>\n<p>And at first this might seem surprising. We might have expected that short lemmas would be the most frequent, but instead we’re seeing long lemmas that always appear, the very longest being:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg8.png' alt='' title='' width='516' height='40'> </div>\n</p></div>\n<p>So why is this? Basically it’s that these long lemmas are being used at the beginning of every proof. They’re the result of applying bisubstitution to the original axiom, and in some sense they seem to be laying down a kind of net in metamathematical space that then allows more diverse—and smaller—lemmas to be derived. </p>\n<p>But how are these “common core” popular lemmas distributed within proofs? Here are a few examples:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDXimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDXimg9.png' alt='' title='' width='566' height='579'> </div>\n</p></div>\n<p>And what we see is that while, yes, the common core lemmas are always at the beginning, they don’t seem to have a uniform way of “plugging into” the rest of the proof. And it doesn’t, for example, seem as if there’s just some small set of (perhaps simple) “waypoint” lemmas that one can introduce that will typically shorten these proofs.</p>\n<p>If one effectively allows all the common core lemmas to be used as axioms, then inevitably proofs will be shortened; for example, the proof of <em>a</em> · <em>b</em> = <em>b</em> · <em>a</em>—which only ends up using 5 of the common core lemmas—is now shortened to 51 lemmas:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDZimg10B.png' alt='' title='' width='282' height='479'> </div>\n</p></div>\n<p>It doesn’t seem to become easier to understand, though. And if it’s unrolled, it’s still 5013 steps. </p>\n<p>Still, one can ask what happens if one just introduces particular “recognizable” lemmas as additional axioms. For example, if we include “commutativity” <em>a</em> · <em>b</em> = <em>b</em> · <em>a</em> then we find that, yes, we do manage to <a href=\"https://www.wolframscience.com/nks/notes-12-9--proof-lengths-in-logic/\">reduce the lengths of some proofs</a>, but certainly not all:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDXimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg11.png' alt='' title='' width='554' height='280'> </div>\n</p></div>\n<p>Are there any other “pivotal” lemmas we could add? In particular, what about lemmas that can help with the length-200 or more proofs? It turns out that all of these proofs involve the lemma: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg12.png' alt='' title='' width='130' height='14'> </div>\n</p></div>\n<p>So what happens if we add this? Well, it definitely reduces proof lengths:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg13.png' alt='' title='' width='607' height='316'> </div>\n</p></div>\n<p>And sometimes it even seems like it brings proofs into “human range”. For example, a proof of</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025lemmasimg14.png' alt='' title='' width='104' height='14'> </div>\n</p></div>\n<p>from our original axiom has length 56. Adding in commutativity reduces it to length 18. And adding our third lemma reduces it to just length 9—and makes it not even depend directly on the original axiom:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDZimg15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025lemmasCLOUDZimg15.png' alt='' title='' width='272' height='249'> </div>\n</p></div>\n<p>But despite the apparent simplicity here, the steps involved—particularly when bisubstitution is used—are remarkably hard to follow. (Note the use of <em>a </em>= <em>a</em> as a kind of “implicit axiom”—something that has actually also appeared, without comment, in many of our other proofs.)</p>\n<h2 id=\"can-we-get-a-shorter-proof\">Can We Get a Shorter Proof?</h2>\n<p>The proof that we’ve been studying can be seen in some ways as a rather arbitrary artifact. It’s the output of <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt>, with all its specific detailed internal algorithms and choices. In the Appendix, we’ll see that other automated theorem proving systems give very similar results. But we still might wonder whether actually the complexity of the proof as we’ve been studying it is just a consequence of the details of our automated theorem proving—and that in fact there’s a much shorter (and perhaps easier to understand) proof that exists.</p>\n<p>One approach we could take—reminiscent of higher category theory—is to think about just simplifying the proof we have, effectively using proof-to-proof transformations. And, yes, this is technically difficult, though it doesn’t seem impossible. But what if there are <a href=\"https://www.wolframscience.com/metamathematics/the-topology-of-proof-space/\">“holes” in proof space</a>? Then a “continuous deformation” of one proof into another will get stuck, and even if there is a much shorter proof, we’re liable to get “topologically stuck” before we find it.</p>\n<p>One way to be sure we’re getting the shortest proof of a particular lemma is to explicitly find the first place that lemma appears in the (future) entailment cone of our original axiom. For example, as we saw above, a single substitution event leads to the entailment cone:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025shorterimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025shorterimg1.png' alt='' title='' width='645' height='285'> </div>\n</p></div>\n<p>Every lemma produced here is, by construction, in principle derivable by a proof involving a single substitution event. But if we actually use <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> to prove these lemmas, the proofs we get most involve 2 events (and in one case 4):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025shorterAimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025shorterAimg2.png' alt='' title='' width='645' height='75'> </div>\n</p></div>\n<p>If we take another step in the entailment cone, we get a total of 5062 lemmas. From the way we generated them, we know that all these lemmas can in principle be reached by proofs of length 2. But if we run <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> on them, we find a distribution of proof lengths:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025shorterimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025shorterimg3.png' alt='' title='' width='314' height='141'> </div>\n</p></div>\n<p>And, yes, there is one lemma (with <tt><a href=\"http://reference.wolfram.com/language/ref/LeafCount.html\">LeafCount</a></tt> 183) that is found only by a proof of length 15. But most often the proof length is 4—or about double what it could be. </p>\n<p>If we generate the entailment cone for lemmas using bisubstitution rather than just ordinary substitution, there are slightly more cases where <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> does worse at getting minimal proofs. </p>\n<p>For example, the lemma</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025shorterimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025shorterimg4.png' alt='' title='' width='671' height='14'> </div>\n</p></div>\n<p>and 3 others can be generated by a single bisubstitution from the original axiom, but <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> gives only proofs of length 4 for all of these.</p>\n<p>What about unrolled proofs, in which one can generate an entailment cone by starting from a particular expression, and then applying the original axiom in all possible ways?

Models and the Proof</h2>\n<p>We can think of logic (or Boolean algebra) as being associated with a certain collection of theorems. And what our axiom does is to provide something from which all theorems of logic (and nothing but theorems of logic) can be derived. At some level, we can think of it as just being about symbolic expressions. But in our effort to understand what’s going on—say with our proof—it’s sometimes useful to ask how we can “concretely” interpret these expressions.</p>\n<p>For example, we might ask what the · operator actually is. And what kinds of things can our symbolic variables be? In effect we’re asking for what in model theory are called <a href=\"https://www.wolframscience.com/metamathematics/the-model-theoretic-perspective/\">“models” of our axiom system</a>. And in aligning with logic the most obvious model to discuss is one in which variables can be <tt><a href=\"http://reference.wolfram.com/language/ref/True.html\">True</a></tt> or <tt><a href=\"http://reference.wolfram.com/language/ref/False.html\">False</a></tt>, and the · represents either the logical operator <tt><a href=\"http://reference.wolfram.com/language/ref/Nand.html\">Nand</a></tt> or the logical operator <tt><a href=\"http://reference.wolfram.com/language/ref/Nor.html\">Nor</a></tt>.</p>\n<p>The truth table, say for <tt>Nand</tt>, is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg1.png' alt='' title='' width='156' height='152'> </div>\n</p></div>\n<p>And as expected, with this model for ·, we can confirm that our original axiom holds:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg2.png' alt='' title='' width='379' height='274'> </div>\n</p></div>\n<p>In general, though, our original axiom allows two size-2 models (that we can interpret as <tt>Nand</tt> and <tt>Nor</tt>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg4.png' alt='' title='' width='98' height='52'> </div>\n</p></div>\n<p>It allows no size-3 models, and in fact in general <a href=\"https://www.wolframscience.com/nks/notes-12-9--operators-on-sets/\">allows only models of size 2<sup><em>n</em></sup></a>; for example, for size 4 its models are:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01082025actuallyimg6.png' alt='' title='' width='551' height='210'> </div>\n</p></div>\n<p>So what about <em>a</em> · <em>b</em> = <em>b</em> · <em>a</em>?

In other words, at least for size-2 models, satisfying the original axiom system implies satisfying <nobr><em>a</em> · <em>b</em> = <em>b</em> · <em>a</em>.</nobr></p>\n<p>And indeed any lemma derived from our axiom system must allow the models associated with our original axiom system. But it may also allow more—and sometimes many more. So here’s a map of our proof, showing how many models (out of 16 possible) each lemma allows:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025KDCLOUDimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025KDCLOUDimg5.png' alt='' title='' width='329' height='674'> </div>\n</p></div>\n<p>Here are the results for size-3 models:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01092025KDCLOUDimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01092025KDCLOUDimg6.png' alt='' title='' width='478' height='972'> </div>\n</p></div>\n<p>And, once again, these look complicated. We can think of models as defining—in some sense—<a href=\"https://www.wolframscience.com/nks/p804--implications-for-mathematics-and-its-foundations/\">what lemmas are “about”</a>. So, for example, our original axiom is “about” <tt>Nand</tt> and <tt>Nor</tt>. The lemma <em>a</em> · <em>b</em> = <em>b</em> · <em>a</em> is “about” symmetric functions. And so on. And we might have hoped that we could gain some understanding of our proof by looking at how different lemmas that occur in it “sculpt” what is being talked about. But in fact we just seem to end up with complicated descriptions of sets that don’t seem to have any obvious relationship with each other.</p>\n<h2 id=\"what-about-a-higher-level-abstraction\">What about a Higher-Level Abstraction?</h2>\n<p>If there’s one thing that stands out about our proof—and the analysis we’ve given of it here—it’s how fiddly and “in the weeds” it seems to be. But is that because we’re missing some big picture? Is there actually a more abstract way of discussing things, that gets to our result without having to go through all the details? </p>\n<p>In the history of mathematics many of the most important themes have been precisely about finding such higher-level abstractions. We could start from the <a href=\"https://www.wolframscience.com/nks/notes-12-9--groups-and-axioms/\">explicit symbolic axioms</a></p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025abstractionimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025abstractionimg1.png' alt='' title='' width='120' height='59'> </div>\n</p></div>\n<p>or even</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025abstractionimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025abstractionimg2.png' alt='' title='' width='165' height='22'> </div>\n</p></div>\n<p>and start building up theorems much as we’ve done here. Or we could recognize that these are axioms for group theory, and then start using the abstract ideas of group theory to derive our theorems.</p>\n<p>So is there some higher-level version of what we’re discussing here? Remember that the issue is not about the overall structure of Boolean algebra; rather it’s about the more metamathematical question of how one can prove that all of Boolean algebra can be generated from the axiom:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025abstractionimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025abstractionimg3.png' alt='' title='' width='183' height='14'> </div>\n</p></div>\n<p>In the last few sections we’ve tried a few semi-empirical approaches to finding higher-level representations. But they haven’t gotten very far. And to get further we’re probably going to need a serious new idea.</p>\n<p>And, if history is a guide, we’re going to need to come up with an abstraction that somehow “goes outside of the system” before “coming back”. It’s like trying to figure out the real roots of a cubic equation, and realizing that the best way to do this is to introduce complex numbers, even though the imaginary parts will cancel at the end. </p>\n<p>In the direct exploration of our proof, it feels as if the intermediate lemmas we generate “wander off into the wilds of metamathematical space” before coming back to establish our final result. And if we were using a higher-level abstraction, we’d instead be “wandering off” into the space of that abstraction. But what we might hope is that—at least with the concepts we would use in discussing that abstraction—the path that would be involved would be “short enough to be accessible to human understanding”.</p>\n<p>Will we be able to find such an abstraction? It’s a subtle question. Because in effect it asks whether we can reduce the computational effort needed for the proof—or, in other words, whether we can find a pocket of computational reducibility in what in general will be a computationally irreducible process. But it’s not a question that can really be answered just for our specific proof on it own. After all, our “abstraction” could in principle just involve introducing a primitive that represents our whole proof or a large part of it. But to make it what we can think of as a real abstraction we need something that spans many different specific examples—and, in our case, likely many axiomatic systems or symbolic proofs.</p>\n<p>So is such an abstraction possible? In the history of mathematics the experience has been that after enough time (often measured in centuries) has passed, abstractions tend to be found. But at some level this has been self fulfilling. Because the areas that are considered to have remained “interesting for mathematics” tend to be just those where general abstractions have in fact been found. </p>\n<p>In <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/\">ruliology</a>, though, the typical experience has been different. Because there it’s been routine to <a href=\"https://www.wolframscience.com/nks/\">sample the computational universe of possible simple programs</a> and encounter computational irreducibility. In the end it’s still inevitable that among the computational irreducibility there must be pockets of computational reducibility. But the issue is that these pockets of computational reducibility may not involve features of our system that we care about. </p>\n<p>So is a proof of the kind we’re discussing here more like ruliology, or more like “typical mathematics”? Insofar as it’s a mathematical-style proof of a mathematical statement it feels more like typical mathematics. But insofar as it’s something found by the computational process of automated theorem proving it perhaps seems more ruliology. </p>\n<p>But what might a higher-level abstraction for it look like? Figuring that out is probably tantamount to finding the abstraction. But perhaps one can at least expect that in some ways it will be metamathematical, and more about the structure and character of proofs than about their content. Perhaps it will be something related to the framework of higher category theory, or some form of meta-algebra. But as of now, we really don’t know—and we can’t even say that such an abstraction with any degree of generality is possible.</p>\n<h2 id=\"llms-to-the-rescue\">LLMs to the Rescue?</h2>\n<p>The unexpected success of LLMs in language generation and related tasks has led to the idea that perhaps eventually <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/\">systems like LLMs will be able to “do everything”</a>—including for example math. We already know—not least thanks to Wolfram Language—that <a href=\"https://www.wolfram.com/mathematica/\">lots of math can be done computationally</a>. But often the computations are hard—and, as in the example of the proof we’re discussing here, incomprehensible to humans. So the question really is: can LLMs “humanize” what has to be done in math, turning everything into a human-accessible narrative? And here our proof seems like an excellent—if challenging—test case. </p>\n<p>But what happens if we just ask a current LLM to generate the proof from scratch? It’s not a good picture. Very often the LLM will eagerly generate a proof, but it’ll be completely wrong, often with the same kind of mistakes that a student somewhat out of their depth might make. Here’s a typical response where an LLM simply assumes that the · operator is associative (which it isn’t in Boolean algebra) then produces a proof that on first blush looks at least vaguely plausible, but is in fact completely wrong:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/01/sw01072025rescueimg1.png' alt='Inadequate LLM proof' title='Inadequate LLM proof' width='611' height='489'/></p>\n<p>Coming up with an explanation for what went wrong is basically an exercise in “LLM psychology”. But in a first approximation one might say the following. LLMs are trained to “fill in what’s typical”, where “typical” is defined by what appears in the training set. But (absent some recent Wolfram Language and <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a> based technology of ours) what’s been available as a training set has been human-generated mathematical texts, where, yes, operators are often associative, and typical proofs are fairly short. And in the “psychology of LLMs” an LLM is much more likely to “do what’s typical” than to “rigorously follow the rules”. </p>\n<p>If you press the LLM harder, then it might just “abdicate”, and suggest using the <a href=\"https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/\">Wolfram Language as a tool</a> to generate the proof. So what happens if we do that, then feed the finished proof to the LLM and ask it to explain? Well, typically it just does what LLMs do so well, and writes an essay:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/01/sw01072025rescueimg2.png' alt='LLM proof essay' title='LLM proof essay' width='614' height='516'/></p>\n<p>So, yes, it does fine in “generally framing the problem”. But not on the details. And if you press it for details, it’ll typically eventually just start parroting what it was given as input. </p>\n<p>How else might we try to get the LLM to help? One thing I’ve certainly wondered is how the lemmas in the proof relate to known theorems—perhaps in quite different areas of mathematics. It’s something one might imagine one would be able to answer by searching the literature of mathematics. But, for example, textual search won’t be sufficient: it has to be some form of <a href=\"https://writings.stephenwolfram.com/2024/07/yet-more-new-ideas-and-new-functions-launching-version-14-1-of-wolfram-language-mathematica/#vector-databases-and-semantic-search\">semantic search</a> based on the meaning or symbolic structure of lemmas, not their (fairly arbitrary) textual presentation. A vector database might be all one needs, but one can certainly ask an LLM too:</p>\n<p><img src='https://content.wolfram.com/sites/43/2025/01/sw01072025rescueimg3.png' alt='LLM semantic search results' title='LLM semantic search results' width='619' height='485'/></p>\n<p>It’s not extremely helpful, though, charmingly, it correctly identifies the source of our original axiom. I’ve tried similar queries for our whole set of lemmas across a variety of LLMs, with a variety of RAG systems. Often the LLM will talk about an interpretation for some lemma—but the lemma isn’t actual present in our proof. But occasionally the LLM will mention possible connections (“band theory”; “left self-distributive operations in quandles”; “Moufang loops”)—though so far none have seemed to quite hit the mark.</p>\n<p>And perhaps this failure is itself actually a result—telling us that the lemmas that show up in our proof really are, in effect, out in the wilds of metamathematical space, probing places that haven’t ever been seriously visited before by human mathematics.</p>\n<p>But beyond LLMs, what about more general machine learning and neural net approaches? Could we imagine <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/#science-as-narrative\">using a neural net as a probe to find “exploitable regularities”</a> in our proof? It’s certainly possible, but I suspect that the systematic algorithmic methods we’ve already discussed for finding optimal notations, popular lemmas, etc. will tend to do better. I suppose it would be one thing if our systematic methods had failed to even find a proof. Then we might have wanted something like neural nets to try to guess the right paths to follow, etc. But as it is, our systematic methods rather efficiently do manage to successfully find a proof. </p>\n<p>Of course, there’s still the issue that we’re discussing here that the proof is very “non-human”. And perhaps we could imagine that neural nets, etc.—especially when trained on existing human knowledge—could be used to “form concepts” that would help us humans to understand the proof. </p>\n<p>We can get at least a rough analogy for how this might work by looking at <a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/\">visual images produced by a generative AI system</a> trained from billions of human-selected images. There’s a concept (like “a cube”) that exists somewhere in the feature space of possible images. But “around” that concept are other things—<a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/#the-notion-of-interconcept-space\">“out in interconcept space”</a>—that we don’t (at least yet) explicitly have words for:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/interconceptimg1_copy.txt' data-c2c-type='text/html'> <img src='https://content.wolfram.com/sites/43/2025/01/sw01072025rescueimg4.png' alt='Interconcept space' title='Interconcept space' width='494' height='494'/></div>\n</p></div>\n<p>And it’ll presumably be similar for math, though harder to represent in something like a visual way. There’ll be existing math concepts. But these will be embedded in a vast domain of “mathematical interconcept space” that we humans haven’t yet “colonized”. And what we can imagine is that—perhaps with the help of neural nets, etc.—we can identify a limited number of “points in interconcept space” that we can introduce as new concepts that will, for example, provide useful “waypoints” in understanding our proof.</p>\n<h2 id=\"but-why-is-the-theorem-true\">But Why Is the Theorem True?</h2>\n<p>It’s a common human urge to think that anything that’s true must be true for a reason. But what about our theorem? Why is it true? Well, we’ve seen a proof. But somehow that doesn’t seem satisfactory. We want “an explanation we can understand”. But we know that in general we can’t always expect to get one.</p>\n<p>It’s a fundamental implication of computational irreducibility that things can happen where the only way to “see how they happen” is just to “watch them happen”; there’s no way to “compress the explanation”.</p>\n<p>Consider the following patterns. They’re all generated by cellular automata. And all <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">live exactly 100 steps before dying out</a>. But why?</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01072025theoremimg1_copy-1.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025theoremimg1-1.png' alt='' title='' width='597' height='509'> </div>\n</p></div>\n<p>In a few cases it seems like we can perhaps at least begin to imagine “narratively describing” a mechanism. But most of the time all we can say is basically that they “live 100 steps because they do”. </p>\n<p>It’s a quintessential consequence of computational irreducibility. It might not be what we’d expect, or hope for. But it’s reality in the computational universe. And it seems very likely that our theorem—and its proof—is like this too. The theorem in effect “just happens to be true”—and if you run the steps in the proof (or find the appropriate path in the entailment cone) you’ll find that it is. But there’s no “narrative explanation”. No “understanding of why it’s true”. </p>\n<h2 id=\"intuition-and-automated-theorem-proving\">Intuition and Automated Theorem Proving</h2>\n<p>We’ve been talking a lot about the proof of our theorem. But where did the theorem to prove come from in the first place? Its immediate origin was an <a href=\"https://www.wolframscience.com/nks/notes-12-9--searching-for-logic-axioms/\">exhaustive search I did of simple axiom systems</a>, filtering for ones that could conceivably generate Boolean algebra, followed by testing each of the candidates using automated theorem proving. </p>\n<p>But how did I even get the idea of searching for a simple axiom system for Boolean algebra? Based on the axiom systems for Boolean algebra known before—and the historical difficulty of finding them—one might have concluded that it was quite hopeless to find an axiom system for Boolean algebra by exhaustive search. But by 2000 I had nearly two decades of experience in exploring the computational universe—and I was well used to the <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/\">remarkable phenomenon</a> that even very simple computational rules can lead to behavior of great complexity. So the result was that when I came to think about axiom systems and the foundations of mathematics my intuition led me to imagine that perhaps the simplest axiom system for something like Boolean algebra might be simple enough to exhaustively search for.</p>\n<p>And indeed discovering the axiom system we’ve discussed here helped further expand and deepen my intuition about the consequences of simple rules. But what about the proof? What intuition might one get from the proof as we now know it, and as we’ve discussed here?</p>\n<p>There’s much intuition to be got from observing the world as it is. But for nearly half a century I’ve had another crucial source of intuition: observing the computational universe—and doing computational experiments. I was recently reflecting on how I came to start developing intuition in this way. And what it might mean for intuition I could now develop from things like automated theorem proving and AI.</p>\n<p>Back in the mid-1970s <a href=\"https://www.stephenwolfram.com/publications/academic/particle-physics\">my efforts in particle physics</a> led me to start using computers to do not just numerical, but <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">also algebraic computations</a>. In numerical computations it was usual to just get a few numbers out, that perhaps one could plot to make a curve. But in algebraic computations one instead got out formulas—and <a href=\"https://content.wolfram.com/sw-publications/2020/07/effective-coupling-qcd.pdf\" target=\"_blank\" rel=\"noopener\">often very ornate ones full of structure and detail</a>. And for me it was routine to get not just one formula, but many. And looking at these formulas I started to develop intuition about them. What functions would they involve? What algebraic form would they take? What kind of numbers would they involve? </p>\n<p>I don’t think I ever consciously realized that I was developing a new kind of computationally based intuition. But I soon began to take it for granted. And when—at the beginning of the 1980s—<a href=\"https://www.wolframscience.com/nks/chap-1--the-foundations-for-a-new-kind-of-science#sect-1-4--the-personal-story-of-the-science-in-this-book\">I started to explore the consequences of simple abstract systems</a> like cellular automata it was natural to expect that I would get intuition from just “seeing” how they behaved. And here there was also another important element. Because part of the reason I concentrated on cellular automata was precisely because one could readily visualize their behavior on a computer. </p>\n<p>I don’t think I would have learned much if I’d just been printing out “numerical summaries” of what cellular automata do. But as it was, I was seeing their behavior in full detail. And—surprising though what I saw was—I was soon able to start getting an intuition for what could happen. It wasn’t a matter of knowing what the value of every cell would be. But I started doing things like identifying four general classes of cellular automata, and then recognizing the phenomenon of computational irreducibility. </p>\n<p>By the 1990s I was much more broadly exploring the computational universe—always trying to see what could happen there. And in almost all cases it was a story of defining simple rules, then running them, and making an explicit step-by-step visualization of what they do—and thereby in effect “seeing computation in action”.</p>\n<p>In recent years—spurred by our <a href=\"https://www.wolframphysics.org\" target=\"_blank\" rel=\"noopener\">Physics Project</a>—I’ve increasingly explored not just computational processes, but also <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\">multicomputational ones</a>. And although it’s more difficult I’ve made every effort to visualize the behavior of multiway systems—and to get intuition about what they do. </p>\n<p>But what about automated theorem proving? In effect, automated theorem proving is about finding a particular path in a multiway system that leads to a theorem we want. We’re not getting to see “complete behavior”; we’re in effect just seeing one particular “solution” for how to prove a theorem. </p>\n<p>And after one’s seen many examples, the challenge once again is to develop intuition. And that’s a large part of what I’ve been trying to do here. It’s crucial, I think, to have some way to visualize what’s happening—in effect because visual input is the most efficient way to get information into our brains. And while the visualizations we’ve developed here aren’t as direct and complete as, say, for cellular automaton evolution, I think they begin to give some overall sense of our proof—and other proofs like it.</p>\n<p>In studying simple programs like cellular automata, the intuition I developed led me to things like my <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-2--four-classes-of-behavior\">classification of cellular automaton behavior</a>, as well as to bigger ideas like the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> and computational irreducibility. So having now exposed myself to automated theorem proving as I exposed myself to algebraic computation and the running of simple rules in the past, what general principles might I begin to see? And might they, for example, somehow make the fact that our proof works ultimately seem “obvious”?</p>\n<p>In some ways yes, but in other ways no. Much as with simple programs, there are axiom systems so simple that, for example, the <a href=\"https://www.wolframscience.com/metamathematics/axiom-systems-in-the-wild/\">multiway systems they generate are highly regular</a>. But beyond a low threshold, it’s common to get very complicated—and in many ways seemingly random—multiway system structures. Typically an infinite number of lemmas are generated, with little or no obvious regularity in their forms.</p>\n<p>And one can expect that—following the ideas of universal computation—it’ll typically be possible to encode in any one such multiway system the behavior of any other multiway system. In terms of axioms what one’s saying is that if one sets up the right translation between theorems, one will be able to use any one such axiom system to generate the theorems of any other. But the issue is that the translation will often make major changes to the structure of the theorems, and in effect define not just a “mathematical translation” (like between geometry and algebra) but a <a href=\"https://www.wolframscience.com/metamathematics/uniformity-and-motion-in-metamathematical-space/#p-146\">metamathematical one (as one would need to get from Peano arithmetic to set theory)</a>. </p>\n<p>And what this means is that it isn’t surprising that even a very simple axiom system can generate a complicated set of possible lemmas. But knowing this doesn’t immediately tell one whether those lemmas will align with some particular existing theory—like Boolean algebra. And in a sense that’s a much more detailed question.</p>\n<p>At some metamathematical level it might not be a natural question. But at a “mathematical level” it is. And it’s what we have to address in connection with the theorem—and proof—we’re discussing here. Many aspects of the overall form and properties of the proof will be quite generic, and won’t depend on the particulars of the axiom system we’re using. But some will. And quite what intuition we may be able to get about these isn’t clear. And perhaps it’ll necessarily be fragmented and specific—in effect responding to the presence of computational irreducibility.</p>\n<p>It’s perhaps worth commenting that LLMs—and machine learning in general—represent another potential source of intuition. That intuition may well be more about the general features of us as observers and thinkers. But such intuition is potentially critical in framing just what we can experience, not only in the natural world, but also in the mathematical and metamathematical worlds. And perhaps the apparent impotence of LLMs when faced with the proof we’ve been discussing already tells us something significant about the nature of “mathematical observers” like us.</p>\n<h2 id=\"so-what-does-it-mean-for-the-future-of-mathematics\">So What Does It Mean for the Future of Mathematics?</h2>\n<p>Let’s say we never manage to “humanize” the proof we’ve been discussing here. Then in effect we’ll end up with a “black-box theorem”—that we can be sure is true—but we’ll never know quite how or why. So what would that mean for mathematics?</p>\n<p>Traditionally, mathematics has tended to operate in a “white box” kind of way, trying to build narrative and understanding along with “facts”. And in this respect it’s very different from natural science. Because in natural science much of our knowledge has traditionally been empirical—derived from observing the world or experimenting on it—and without any certainty that we can “understand its origins”. </p>\n<p>Automated theorem proving of the kind we’re discussing here—or, for that matter, pretty much any exploratory computational experimentation—aligns mathematics much more with natural science, deriving what’s true without an expectation of having a narrative explanation of why. </p>\n<p>Could one imagine practicing mathematics that way? One’s already to some extent following such a path as soon as one introduces axiom systems to base one’s mathematics on. Where do the axiom systems come from? In <a href=\"https://writings.stephenwolfram.com/2020/09/the-empirical-metamathematics-of-euclid-and-beyond/\">the time of Euclid</a> perhaps they were thought of as an idealization of nature. But in more modern times they are realistically much more the result of human choice and human aesthetics.</p>\n<p>So let’s say we determine (given a particular axiom system) that some black-box theorem is true. Well, then we can just add it, just as we could another axiom. Maybe one day it’ll be possible to prove <a href=\"https://www.wolframscience.com/nks/p765--undecidability-and-intractability/\">P≠NP</a> or the <a href=\"https://writings.stephenwolfram.com/2021/03/after-100-years-can-we-finally-crack-posts-problem-of-tag-a-story-of-computational-irreducibility-and-more/#classic-unsolved\">Riemann Hypothesis</a> from existing axioms of mathematics (if they don’t in fact turn out to be independent). And—black box or not—we can expect to add them to what we assume in subsequent mathematics we do, much as they’re routinely added right now, even though their status isn’t yet known. </p>\n<p>But it’s one thing to add one or two “black-box theorems”. But what happens when black-box theorems—that we can think of as “experimentally determined”—start to dominate the landscape of mathematics? </p>\n<p>Well, then mathematics will take on much more of the character of ruliology—or of an experimental science. When it comes to the applications of mathematics, this probably won’t make much difference, except that in effect mathematics will be able to become much more powerful. But the “inner experience” of mathematics will be quite different—and much less “human”.</p>\n<p>If one indeed starts from axioms, it’s not at the outset obvious why everything in mathematics should not be mired in the kind of alien-seeming metamathematical complexity that we’ve encountered in the discussion of our proof here. But <a href=\"https://www.wolframscience.com/metamathematics/mathematics-and-physics-have-the-same-foundations/\">what I’ve argued elsewhere</a> is that the fact that in our experience of doing mathematics it’s not is a reflection of how “mathematical observers like us” sample the raw metamathematical structure generated by axioms (or ultimately by the <a href=\"https://www.wolframscience.com/metamathematics/going-below-axiomatic-mathematics/\">subaxiomatic structure of the ruliad</a>). </p>\n<p>The physics analogy I’ve used is that we succeed in doing mathematics at a “fluid dynamics level”, far above the detailed “molecular dynamics level” of things like the proof we’ve discussed here. Yes, we can ask questions—like ones about the structure of our proof—that probe the axiomatic “molecular dynamics level”. But it’s an important fact that in doing what we normally think of as mathematics we almost never have to; there’s a coherent way to operate purely at the “fluid dynamics level”.</p>\n<p>Is it useful to “dip down” to the molecular dynamics? Definitely yes, because that’s where we can readily do computations—like those in our proof, or in general those going on in the internals of the Wolfram Language. But a key idea in the design of the Wolfram Language is to provide a computational language that can express concepts at a humanized “fluid dynamics” level—in effect bridging between the way humans can think and understand things, and the way raw computation can be done with them.</p>\n<p>And it’s notable that while we’ve had great success over the years in defining “human-accessible” high-level representations for what amount to the “inputs” and “outputs” of computations, that’s been much less true of the “ongoing processes” of computation—or, for example, of the innards of proofs. </p>\n<p>Is there a good “human-level” way to represent proofs? If the proofs are short, it’s not too difficult (and the <a href=\"https://www.wolframalpha.com/pro/step-by-step-math-solver\">step-by-step solutions technology of Wolfram|Alpha</a> provides a good large-scale example of what can be done). But—as we’ve discussed—computational irreducibility implies that some proofs will inevitably be long. </p>\n<p>If they’re not too long, then at least some parts of them might be constructed by human effort, say in a system like a proof assistant. But as soon as there’s much automation (whether with automated theorem proving or with LLMs) it’s basically inevitable that one will end up with things that at least approach what we’ve seen with the proof we’re discussing here. </p>\n<p>What can then be done? Well, that’s the challenge. Maybe there is some way to simplify, abstract or otherwise “humanize” the proof we’ve been discussing. But I rather doubt it. I think this is likely one of those cases where we inevitably find ourselves face to face with computational irreducibility. </p>\n<p>And, yes, there’s important science (particularly ruliology) to do on the structures we see. But it’s not mathematics as it’s traditionally been practiced. But that’s not to say that the results that come out of things like our proof won’t be useful for mathematics. They will be. But they make mathematics more like an experimental science—where what matters most is in effect the input and output rather than a “publishable” or human-readable derivation in between. And where the key issue in making progress is less in the innards of derivations than in defining clear computational ways to express input and output. Or, in effect, in capturing “human-level mathematics” in the primitives and structure of <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">computational language</a>. </p>\n<h2 id=\"appendix-what-about-a-different-theorem-proving-system\">Appendix: What about a Different Theorem Proving System?</h2>\n<p>The proof we’ve been discussing here was created using <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt> in the Wolfram Language. But what if we were to use a different automated theorem proving system? How different would the results be? In the spectrum of things that automated theorem proving systems do, our proof here is on the difficult end. And many existing automated theorem proving systems don’t manage to do it all. But some of the stronger ones do. And in the end—despite their different internal algorithms and heuristics—it’s remarkable how similar the results they give are to those from the Wolfram Language <tt>FindEquationalProof</tt> (differences in the way lemmas vs. inference steps, etc. are identified make detailed quantitative comparisons difficult):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/01/sw01082025appendixCLOUDZimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2025/01/sw01072025appendiximg1.png' alt='' title='' width='650' height='433'> </div>\n</p></div>\n<h2 id='thanks' style='font-size:1.2rem'>Thanks</h2>\n<p style='font-size:90%'>Thanks to Nik Murzin of the <a href=\"https://wolframinstitute.org/\" target=\"_blank\" rel=\"noopener\">Wolfram Institute</a> for his extensive help as part of the Wolfram Institute Empirical Metamathematics Project.

Turning Words into Computation</h2>\n<p>Nearly a year and a half ago—just a few months after <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">ChatGPT burst on the scene</a>—we introduced the <a href=\"https://writings.stephenwolfram.com/2023/06/introducing-chat-notebooks-integrating-llms-into-the-notebook-paradigm/\">first version of our Chat Notebook technology</a> to integrate LLM-based chat into <a href=\"https://www.wolfram.com/notebooks/\">Wolfram Notebooks</a>. For the past year and a half we’ve been building on those foundations. And today I’m excited to be able to announce that we’re releasing the fruits of those efforts: the first version of our <a href=\"https://www.wolfram.com/notebook-assistant-llm-kit/\">Wolfram Notebook Assistant</a>.</p>\n<p>There are all sorts of gimmicky AI assistants out there. But Notebook Assistant isn’t one of them. It’s a serious, deep piece of new technology, and what’s more important, it’s really, really useful! In fact, I think it’s so useful as to be revolutionary. Personally, I thought I was a pretty efficient user of <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>—but Notebook Assistant has immediately made me not only significantly more efficient, but also more ambitious in what I try to do. I hadn’t imagined just how useful Notebook Assistant was going to be. But seeing it now I can say for sure that it’s going to raise the bar for what everyone can do. And perhaps most important of all, it’s going to open up computational language and computational thinking to a vast range of new people, who in the past assumed that those things just weren’t accessible to them. </p>\n<p>Leveraging the decades of work we’ve done on the <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\">design and implementation</a> of the Wolfram Language (and <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>), Notebook Assistant lets people just say in their own words what they want to do; then it does its best to crispen it up and give a computational implementation. Sometimes it goes all the way and just delivers the answer. But even when there’s no immediate “answer” it does remarkably well at building up structures where things can be represented computationally and tackled concretely. People really don’t need to know anything about <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">computational language</a>—or <a href=\"https://writings.stephenwolfram.com/2016/09/how-to-teach-computational-thinking/#what-is-computational-thinking\">computational thinking</a> to get started; Notebook Assistant will take their ideas, rough as they may be, and frame them in computational language terms.<span id=\"more-63574\"></span></p>\n<p>I’ve long seen Wolfram Language as uniquely providing the infrastructure and “notation” to enable “computational X” for all fields X. I’m excited to say that I think Notebook Assistant now bridges “the last mile” to let anyone—at almost any level—access the power of computational language, and “do computational X”. In its original conception, Wolfram Notebook Assistant was just intended to be “useful”. But it’s emerging as something much more than that; something positively revolutionary.</p>\n<p>“I can’t believe it’ll do anything useful with <em>that</em>”, I’ll think. But then I’ll try it. And, very often, something amazing will happen. Something that gets me past some sticking point or over some confusion. Something that gives me an unexpected new building block—or new idea—for what I’m trying to do. And that uses the medium of our computational language to take me beyond where I would ever have reached before.</p>\n<p>So how does one use Notebook Assistant? Once you’ve <a href=\"https://www.wolfram.com/notebook-assistant-llm-kit/#pricing\">signed up</a> you can just go to the toolbar of any notebook, and open a Notebook Assistant chat window:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/12/sw12072024wordsAimg1.png' alt='Notebook Assistant chat window' title='Notebook Assistant chat window' width='608' height='292'/></p>\n<p>Now tell Notebook Assistant what you want to do. The more precise and explicit you are, the better. But you don’t have to have thought things through. Just type what comes into your mind. Imagine you’ve been working in a notebook, and (somehow) you’ve got a picture of some cats. You wonder “How can I find the cats in this picture?” Well, just ask Notebook Assistant!</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/12/sw12072024wordsAimg2.png' alt='How can I find the cats in this picture?' title='How can I find the cats in this picture?' width='617' height='436'/></p>\n<p>Notebook Assistant gives some narrative text, and then a piece of Wolfram Language code—which you can just run in your notebook (by pressing <img loading='lazy' style=\"margin-bottom: -7px\" src='https://content.wolfram.com/sites/43/2024/12/sw12072024wordsAimg3.png' alt='Click to enlarge' title='Click to enlarge' width='126' height='23'/>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12072024wordsAimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/cats-v3.png' alt='' title='' width='570' height='307'> </div>\n</p></div>\n<p>It seems a bit like magic. You say something vague, and Notebook Assistant turns it into something precise and computational—which you can then run. It’s not always as straightforward as in this example. But the important thing is that in practice (at least in my rather demanding experience) Notebook Assistant essentially always does spectacularly well at being useful—and at telling me things that move forward what I’m trying to do.</p>\n<h2 id=\"big-or-small-just-try-it\">Big or Small, Just Try It!</h2>\n<p>Imagine that sitting next to you, you had someone very knowledgeable about <a href=\"https://wolfram.com/language/\">Wolfram Language</a> and about computational thinking in general. Think what you might ask them. That’s what you should ask Notebook Assistant. And if there’s one thing to communicate here, it’s “Just try it!” You might think what you’re thinking about is too vague, or too specific, or too technical. But just try asking Notebook Assistant. In my experience, you’ll be amazed at what it’s able to do, and how helpful it’s able to be.</p>\n<p>Maybe you’re an experienced Wolfram Language user who “knows there must be a way to do something”, but can’t quite remember how. Just ask Notebook Assistant. And not only will it typically be able to find the function (or whatever) you need; it’ll also usually be able to create a code fragment that does the very specific thing you asked about. And, by the way, it’ll save you lots of typing (and debugging) by filling in those fiddly options and so on just how you need them. And even if it doesn’t quite nail it, it’ll have given a skeleton of what you need, that you can then readily edit. (And, yes, the fact that it’s realistic to edit it relies on the fact that Wolfram Language represents it in a way that humans can readily read as well as write.)</p>\n<p>What if you’re a novice, who’s never used Wolfram Language before, and never really been exposed to computational thinking, or for that matter, “techie stuff” at all? Well, the remarkable thing is that Notebook Assistant will still be able to help you—a lot. You can ask it something very vague, that doesn’t even seem particularly computational. It does remarkably well at “computationalizing things”. Taking what you’ve said, and finding a way to address it computationally—and to lead you into the kind of computational thinking that’ll be needed for the particular thing you’re trying to do.</p>\n<p>In what follows, we’ll see a whole range of different ways to use Notebook Assistant. In fact, even as I’ve been writing this, I’ve discovered quite a few new ways to use it that I’d never thought of before. </p>\n<p>There are some general themes, though. The most important is the way Notebook Assistant pivotally relies on the Wolfram Language. In a sense, the main mission of Notebook Assistant is to make things computational. And the whole reason it can so successfully do that is that it has the Wolfram Language as its target. It’s leveraging the unique nature of the Wolfram Language as a full-scale computational language, able to coherently represent abstract and real-world things in a computational way.</p>\n<p>One might think that the Wolfram Language would in the end be mainly an “implementation layer”—serving to make what Notebook Assistant produces runnable. But in reality it’s very, very much more than that. In particular, it’s basically the medium—the language—in which computational ideas are communicated. When Notebook Assistant generates Wolfram Language, it’s not just something for the computer to run; it’s also something for humans to read. Yes, Notebook Assistant can produce text, and that’s useful, especially for contextualizing things. But the most concentrated and poignant communication comes in the Wolfram Language it produces. Want the TL;DR? Just look at the Wolfram Language code!</p>\n<p>Part of how Wolfram Language code manages to communicate so much so efficiently is that it’s precise. You can just mention the name of a function, and you know precisely what it does. You don’t have to “scaffold” it with text to make its meaning clear. </p>\n<p>But there’s something else as well. With its symbolic character—and with all the coverage and consistency that we’ve spent so much effort on over the decades—the Wolfram Language is uniquely able to “communicate in fragments”. Any fragment of Wolfram Language code can be run, and more important, it can smoothly fit into a larger structure. And that means that even small fragments of code that Notebook Assistant generates can be used as building blocks. </p>\n<p>It produces Wolfram Language code. You read the code (and it’s critical that it’s set up to be read). You figure out if it’s what you want. (And if it’s not, you edit it, or ask Notebook Assistant to do that.) Then you can use that code as a robust building block in whatever structure—large or small—that you might be building.</p>\n<p>In practice, a critical feature is that you don’t have to foresee how Notebook Assistant is going to respond to what you asked. It might nail the whole thing. Or it might just take steps in the right direction. But then you just look at what it produced, and decide what to do next. Maybe in the end you’ll have to “break the problem down” to get Notebook Assistant to deal with it. But there’s no need to do that in advance—and Notebook Assistant will often surprise you by how far it’s able to get on its own.</p>\n<p>You might imagine that Notebook Assistant would usually need you to break down what you’re asking into “pure computational questions”. But in effect it has good enough “general knowledge” that it doesn’t. And in fact it will usually do better the more context you give it about why you’re asking it to do something. (Is it for chemical engineering, or for sports analytics, or what?)</p>\n<p>But how ambitious can what you ask Notebook Assistant be? What if you ask it something “too big”? Yes, it won’t be able to solve that 100-year-old problem or build a giant software system in its immediate output. But it does remarkably well at identifying pieces that it can say something about, and that can help you understand how to get started. So, as with many things about Notebook Assistant, you shouldn’t assume that it won’t be helpful; just try it and see what happens! And, yes, the more you use Notebook Assistant, the more you’ll learn just what kind of thing it does best, and how to get the most out of it.</p>\n<p>So how should you ultimately think about Notebook Assistant? Mainly you should think of it like an very knowledgeable and hardworking expert. But at a more mundane level it can serve as a super-enhanced <a href=\"https://reference.wolfram.com/language/\">documentation</a> lookup system or code completion system. It can also take something vague you might ask it, and somehow undauntedly find the “closest formalizable construct”—that it can then compute with. </p>\n<p>An important feature is that it is—in human terms—almost infinitely patient and hardworking. Where a human might think: “it’s too much trouble to write out all those details”, Notebook Assistant just goes ahead and does it. And, yes, it saves you huge amounts of typing. But, more important, it makes it “cheap” to do things more perfectly and more completely. So that means you actually end up labeling those plot axes, or adding a comment to your code, or coming up with meaningful names for your variables.</p>\n<p>One of the overarching points about Notebook Assistant is that it lowers the barrier to getting help. You don’t have to think carefully about formulating your question. You don’t have to go clicking through lots of links. And you don’t have to worry that it’s too trivial to waste a coworker’s time on the question. You can just ask Notebook Assistant. Oh, and it’ll give you a response immediately. (And you can go back and forth with it, and ask it to clarify and refine things.)</p>\n<h2 id=\"how-can-i-do-that\">“How Can I Do That?”</h2>\n<p>At least for me it’s very common: you have something in your mind that you want to do, but you don’t quite know how to achieve it in the <a href=\"https://wolfram.com/language/\">Wolfram Language</a>. Well, now you can just ask Notebook Assistant! </p>\n<p>I’ll show various examples here. It’s worth emphasizing that these examples typically won’t look exactly the same if you run them again. Notebook Assistant has a certain amount of “AI-style random creativity”—and it also routinely makes use of what you’ve done earlier in a session, etc. It also has to be said that Notebook Assistant will sometimes make mistakes—or will misunderstand what you’re asking it. But if you don’t like what it did, you can always press the <img loading='lazy' style=\"margin-bottom: -1px\" src='https://content.wolfram.com/sites/43/2024/12/sw12092024regeneratebutton.png' alt='' title='' width='16' height='16'> button to generate a new response. </p>\n<p>Let’s start off with a basic computational operation: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12092024howupdateimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12092024howupdateimg1.png' alt='' title='' width='370' height='37'> </div>\n<p id=\"examplegallery\"><a \nclass=\"magnific image\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/How-Can-I-Do-That-01-output-zoom-v2.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/How-Can-I-Do-That-01-output-v2.png\" height=\"252\" width=\"400\"\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>As an experienced user of Wolfram Language, a simple “do it with <tt><a href=\"http://reference.wolfram.com/language/ref/FoldList.html\">FoldList</a></tt>” would already have been enough. But Notebook Assistant goes all the way—generating specific code for exactly what I asked. Courtesy of Wolfram Language, the code is very short and easy to read. But Notebook Assistant does something else for one as well: it produces an example of the code in action—which lets one check that it really does what one wanted. Oh, and then it goes even further, and tells me about a function in the <a href=\"https://resources.wolframcloud.com/FunctionRepository\">Wolfram Function Repository</a> (that I, for one, had never heard of; wait did I write it?) that directly does the operation I want.</p>\n<p>OK, so that was a basic computational operation. Now let’s try something a little more elaborate:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/11/NAtest3img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/11/How-Can-I-Do-That-02-input-v2.png' alt='' title='' width='399' height='37'> </div>\n</p></div>\n<p id=\"examplegallery\"><a \nclass=\"magnific image\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/How-Can-I-Do-That-02-output-zoom-v2.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/How-Can-I-Do-That-02-output-v2.png\" width='620' height='430'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>This involves several steps, but Notebook Assistant nails it, giving a nice example.

Assistant provides a very powerful way to go from words to computational results. So what then is the role of computational language and of “raw Wolfram Language”? First of all, it’s the Wolfram Language that makes everything we’ve seen here work; it’s what the words are being turned into so that they can be computed from. But there’s something much more than that. The Wolfram Language isn’t just for computers to compute with. It’s also for humans to think with. And it’s an incredibly powerful medium for that thinking. Like a great generalization of mathematical notation from the distant past, it provides a streamlined way to broadly formalize things in computational terms—and to systematically build things up. </p>\n<p>Notebook Assistant is great for getting started with things, and for producing a first level of results. But words aren’t ultimately an efficient way say how to build up from there. You need the crisp, formal structure of computational language. In which even the tiny amounts of code you write can be incredibly powerful. </p>\n<p>Now that I’ve been using Notebook Assistant for a while I think I can say that on quite a few occasions it’s helped me launch things, it’s helped me figure out details, and it’s helped me debug things that have gone wrong. But the backbone of my computational progress has been me writing Wolfram Language myself (though quite often starting from something Notebook Assistant wrote). Notebook Assistant is an important new part of the “on ramp” to Wolfram Language; but it’s raw Wolfram Language that lets one really zoom forward to build new structures and achieve what’s computationally possible.</p>\n<h2 id=\"where-do-i-start\">“Where Do I Start?”</h2>\n<p>Computational thinking is an incredibly powerful approach. But sometimes it’s hard to get started with, particularly if you’re not used to it. And although one might not imagine it, Notebook Assistant can be very useful here, essentially helping one brainstorm about what direction to take.</p>\n<p>I was explaining this to our head of Sales, and tried:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/11/sw11262024whereimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/11/sw11262024whereimg1.png' alt='' title='' width='370' height='38'> </div>\n</p></div>\n<p id=\"examplegallery\"><a \nclass=\"magnific image\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/Where-Do-I-Start-01-output-zoom.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw11262024whereimg2.png\" width='618' height='521'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>I really didn’t expect this to do anything terribly useful … and I was frankly amazed at what happened.

I’m trying to invent a good system for finding books in my library. I just took a picture of a shelf of books behind my desk:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/11/sw11262024whereimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12092024wherebooks.png' alt='' title='' width='370' height='37'> </div>\n</p></div>\n<p id=\"examplegallery\"><a \nclass=\"magnific image\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/Where-Do-I-Start-03-output-zoom.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw11262024whereimg6.png\" width='399' height='937'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>Once again, a very impressive result. Not the final answer, but a surprisingly good start.

And when one gets used to using it, it starts to be quite natural to just try it on all sorts of things one’s thinking about. But if it’s just “quick, tell me something to compute”, it’s usually harder to come up with anything.</p>\n<p>And that reminds me of the very first time I ever saw a computer in real life. It was 1969 and I was 9 years old (and the computer was an IBM mainframe). The person who was showing me the computer asked me: “So what do you want to compute?” I really had no idea at that time “what one might compute”. Rather lamely I said “the weight of a dinosaur”. So, 55 years later, let’s try that again:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg11.png' alt='' title='' width='370' height='37'> </div>\n</p></div>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg12.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg12.png\" width='536' height='210'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>And let’s try going further:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg13.png' alt='' title='' width='370' height='37'> </div>\n</p></div>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg14.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024whereBimg14.png\" width='552' height='260'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<h2 id=\"tweak-the-details-for-me\">“Tweak the Details for Me”</h2>\n<p>Something I find very useful with Notebook Assistant is having it “tweak the details” of something I’ve already generated. For example, let’s say I have a basic plot of a sine curve in a notebook:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/Tweak-the-Details-img2.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/Tweak-the-Details-img2.png\" width='619' height='161'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>Assuming I have that notebook in focus, Notebook Assistant will “see” what’s there. So then I can tell it to modify my sine curve—and what it will do is produce new code with extra details added:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg4.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg4.png\" width='624' height='254'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>That’s a good result. But as a Wolfram Language aficionado I notice that the code is a bit more complicated than it needs to be. So what can I do about it? Well, I can just ask Notebook Assistant to simplify it:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg6.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg6.png\" width='619' height='228'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>I can keep going, asking it to further “embellish” the plot:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg8.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg8.png\" width='619' height='202'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>Let’s push our luck and try going even further:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg10.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg10.png\" width='619' height='239'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>Oops. Something went wrong. No callouts, and a pink “error” box. I tried regenerating a few times. Often that helps. But this time it didn’t seem to. So I decided to give Notebook Assistant a suggestion:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg12.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024tweakBimg12.png\" width='619' height='230'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>And now it basically got it. And with a little more back and forth I can expect to get exactly what I want. </p>\n<p>In the Wolfram Language, functions (like <tt><a href=\"http://reference.wolfram.com/language/ref/Plot.html\">Plot</a></tt>) are set up to have good automatic defaults. But when you want, for example, to achieve some particular, detailed look, you often have to end up specifying all sorts of additional settings. And Notebook Assistant is very good at doing this, and in effect, patiently typing out all those option settings, etc.</p>\n<h2 id=\"what-went-wrong-fix-it\">“What Went Wrong? Fix It!”</h2>\n<p>Let’s say you wrote some <a href=\"https://wolfram.com/language/\">Wolfram Language</a> (or perhaps Notebook Assistant did it for you). And let’s say it doesn’t work. Maybe it just produces the wrong output. Or maybe it generates all sorts of messages when it runs. Either way, you can just ask the Assistant “What went wrong?”</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/What-Went-Wrong-img2C.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/What-Went-Wrong-img2C.png\" width='620' height='105'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>Here the Assistant rather patiently and clearly explained the message that was generated, then suggested “correct code”:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/What-Went-Wrong-img3C.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/What-Went-Wrong-img3C.png\" width='620' height='103'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>The Assistant tends to be remarkably helpful in situations like this—even for an experienced Wolfram Language user like me. In a sense, though, it has an “unfair advantage”. Not only has it learned “what’s reasonable” from seeing large amounts of Wolfram Language code; it also has access to “internal information”—like a stream of telemetry about messages that were generated (as well as stack traces, etc.). </p>\n<p>In general, Notebook Assistant is rather impressive at “spotting errors” even in long and sophisticated pieces of Wolfram Language code—and in suggesting possible fixes. And I can say that this is a way in which using Notebook Assistant has immediately saved me significant time in doing things with Wolfram Language.</p>\n<h2 id=\"improve-my-code\">“Improve My Code”</h2>\n<p>Notebook Assistant doesn’t just know how to write <a href=\"https://wolfram.com/language/\">Wolfram Language</a> code; it knows how to write good Wolfram Language code. And in fact if you give it even a sloppy “outline” of Wolfram Language code, the Assistant is usually quite good at making it clean and complete. And that’s important not only in being able to produce code that will run correctly; it’s also important in making code that’s clear enough that you can understand it (courtesy of the readability of good Wolfram Language code).</p>\n<p>Here’s an example starting with a rather horrible piece of Wolfram Language code on the right:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/sw112720240840img2.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw112720240840img2.png\" width='620' height='349'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>The code on the right is quite buggy (it doesn’t initialize <tt>list</tt>, for example). But Notebook Assistant guesses what it’s supposed to do, and then makes nice “Wolfram style” versions, explaining what it’s doing.</p>\n<p>If the code you’re dealing with is long and complicated, Notebook Assistant may (like a person) get confused. But you can always select a particular part, then ask Notebook Assistant specifically about that. And the symbolic nature—and coherence—of the Wolfram Language will typically mean that Notebook Assistant will be able to act “modularly” on the piece that you’ve selected.</p>\n<p>Something I’ve found rather useful is to have Notebook Assistant refactor code for me. Here I’m starting from a sequence of separate inputs (yes, itself generated by Notebook Assistant) and I’m turning it into a single function:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/sw112720240840img4.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw112720240840img4.png\" width='620' height='276'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>Now we can use the function however we want:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/sw112720240840img5.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw112720240840img5.png\" width='620' height='223'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>Going the other way is useful too.

But (as with prose and math) you sometimes need a more detailed exploration. And providing narrative explanations of code is something else that Notebook Assistant is good at. Here it’s taking a <a href=\"https://www.wolframscience.com/nks/notes-10-5--lengths-of-number-representations/\">single line of (rather elegant) Wolfram Language code</a> and writing a whole essay about what the code is doing: </p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/sw11272024explainimg2.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw11272024explainimg2.png\" width='620' height='520'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>What if you have a long piece of code, and you just want to explain some small part of it? Well, since Notebook Assistant sees selections you make, you can just select one part of your code, and Notebook Assistant will know that’s what you want to explain.</p>\n<h2 id=\"fill-in-the-paperwork-for-me\">“Fill in the Paperwork for Me”</h2>\n<p>The <a href=\"https://wolfram.com/language/\">Wolfram Language</a> is carefully designed to have built-in functions that just “do what you need”, without having to use idioms or set up repeated boilerplate. But there are situations where there’s inevitably a certain amount of “bureaucracy” to do. For example, let’s say you’re writing a function to deploy to the Function Repository. You enter the definition for the function into a <a href=\"https://writings.stephenwolfram.com/2019/06/the-wolfram-function-repository-launching-an-open-platform-for-extending-the-wolfram-language/#contributing-to-the-repository\">Function Resource Definition Notebook</a>. But now you have to fill in documentation, examples, etc. And in fact that’s often the part that typically takes the longest. But now you can ask Notebook Assistant to do it for you. Here I put the cursor in the Examples section:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/sw11272024paperworkimg2.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw11272024paperworkimg2.png\" width='620' height='253'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>It’s always a good idea to set up tests for functions you define. And this is another thing Notebook Assistant can help with:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/11/sw11272024paperworkimg4.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/11/sw11272024paperworkimg4.png\" width='620' height='846'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<h2 id=\"the-inspiration-button\">The “Inspiration Button” <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/11/sw11272024inspirationimg2.png' alt='' title='' width='11' height='18'/></h2>\n<p>All the examples of interacting with Notebook Assistant that we’ve seen so far involve using the Notebook Assistant window, that you can open with the <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/11/sw11272024inspirationimg3.png' alt='' title='' width='16' height='16'/> button on the notebook toolbar. But another method involves using the <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/11/sw11272024inspirationimg4.png' alt='' title='' width='20' height='18'/> button in the toolbar, which we’ve been calling the “inspiration button”.</p>\n<p>When you use the Notebook Assistant window, the Assistant will always try to figure out what you’re talking about. For example, if you say “Plot that” it’ll use what it knows about what notebook you’re using, and where you are in it, to try to work out what you mean by “that”. But when you use the <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/11/sw11272024inspirationimg4.png' alt='' title='' width='20' height='18'/> button it’ll specifically try to “provide inspiration at your current selection”. </p>\n<p>Let’s say you’ve typed <tt><a href=\"http://reference.wolfram.com/language/ref/Plot.html\">Plot</a></tt><tt>[</tt><tt><a href=\"http://reference.wolfram.com/language/ref/Sin.html\">Sin</a></tt><tt>[x]</tt>.

Here’s what it suggests (and, yes, in this case, those aren’t such bad ideas):</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/sw12072024magicimg3.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12072024magicimg3.png\" width='620' height='666'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<h2 id=\"the-practicalities-of-the-assistant\">The Practicalities of the Assistant</h2>\n<p>One of the objectives for Notebook Assistant is to have it provide “hassle-free” access to AI and LLM technology integrated into the Wolfram System. And indeed, once you’ve set up your subscription (within <a href=\"https://account.wolfram.com/products\" target=\"_blank\">your Wolfram Account</a>), everything “just works”. Under the hood, there’s all sorts of technology, servers, etc. But you don’t have to worry about any of that; you can just use Notebook Assistant as a built-in part of the Wolfram Notebook experience.</p>\n<p>As you work with Notebook Assistant, you’ll get progressively better intuition about where it can best help you. (And, yes, we’ll be continually updating Notebook Assistant, so it’ll often be worth trying things again if a bit of time has passed.) Notebook Assistant—like any AI-based system—has definite human-like characteristics, including sometimes making mistakes. Often those mistakes will be obvious (e.g. code with incorrect syntax colored red); sometimes they may be more difficult to spot. But the great thing about Notebook Assistant is that it’s firmly anchored to the “solid ground” of Wolfram Language. And any time it writes Wolfram Language code that you can see does what you want, you can always confidently use it.</p>\n<p>There are some things that will help Notebook Assistant do its best for you. Particularly important is giving it the best view of the “context” for what you ask it. Notebook Assistant will generally look at whatever has already been said in a particular chat. So if you’re going to change the subject, it’s best to use the <img style=\"margin-top: 2px;position:relative;top:3px;\" src='https://content.wolfram.com/sites/43/2024/12/newchat-buttom.png' alt='' title='' width='20' height='17'/> button to start a new chat, so Notebook Assistant will focus on the new subject, and not get confused by what you (or it) said before. </p>\n<p>When you open the Notebook Assistant chat window you’ll often want to talk about—or refer to—material in some other notebook. Generally Notebook Assistant will assume that the notebook you last used is the one that’s relevant—and that any selection you have in that notebook is the thing to concentrate on the most. If you want Notebook Assistant to focus exclusively on what you’re saying in the chat window, one way to achieve that is to start a blank notebook. Another approach is to use the <img style=\"margin-top: 2px;position:relative;top:6px;\" loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/NA-sidechat-sources.png' alt='' title='' width='70' height='23'> menu, which provides more detailed control over what material Notebook Assistant will consider. (For now, it just deals with notebooks you have open—but external files, URLs, etc. are coming soon.) </p>\n<p>Notebook Assistant will by default store all your chat sessions. You can see your chat history (with chats automatically assigned names by the Assistant) by pressing the <img style=\"margin-top: 2px;position:relative;top:3px;\" src='https://content.wolfram.com/sites/43/2024/12/NA-sidechat-history.png' alt='' title='' width='18' height='18'/> History button. You can delete chats from your history here. You can also “pop out” chats with <img style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/12/NA-sidechat-history-popout.png' alt='' title='' width='15' height='15'/>, creating standalone notebooks that you can save, send to other people, etc. </p>\n<p>So what’s inside Notebook Assistant? It’s quite a tower of technology. The core of its “linguistic interface” is an LLM (actually, several different LLMs)—trained on extensive Wolfram Language material, and with access to a variety of tools, especially Wolfram Language evaluators. Also critical to Notebook Assistant is its access to a variety of RAGs based on vector databases, that it uses for immediate semantic search of material such as Wolfram Language documentation. Oh, and then there’s a lot of technology to connect Notebook Assistant to the symbolic internal structure of notebooks, etc.</p>\n<p>So when you use Notebook Assistant, where is it actually running? Its larger LLM tasks are currently running on cloud servers. But a substantial part of its functionally is running right on your computer—using Wolfram Language (notably the <a href=\"https://reference.wolfram.com/language/guide/MachineLearning.html\">Wolfram machine learning framework</a>, vector database system, etc.) And because these things are running locally, the Assistant can request access to local information on your computer—as well as avoiding the latency of accessing cloud-based systems.</p>\n<h2 id=\"chats-in-your-main-notebook-coming-soon\">Chats in Your Main Notebook (Coming Soon)</h2>\n<p>Much of the time, you want your interactions with Notebook Assistant to be somehow “off on the side”—say in the Notebook Assistant window, or in the inspiration button menu. But sometimes you want your interactions to be right in your main notebook.</p>\n<p>And for this you’ll soon (in Version 14.2) be able to use an enhanced version of the <a href=\"https://writings.stephenwolfram.com/2023/06/introducing-chat-notebooks-integrating-llms-into-the-notebook-paradigm/\n\">Chat Notebook</a> technology that we developed last year, not just in a separate “Chat Notebook”, but fully integrated into any notebook. </p>\n<p>At the beginning of a cell in any notebook, just press <span class=\"kbd\"><kbd>‘</kbd></span>. You get a chat cell that communicates with Notebook Assistant:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12082024chatinputA.png' alt='Chat cell' title='Chat cell' width='711' height='43'></p>\n<p>And now the output from that chat cell is placed directly below in the notebook—so you can create a notebook that mixes standard notebook content with chat content.</p>\n<p>It all works basically just like a fully integrated version of our Chat Notebook technology. (And this functionality is already available in Version 14.1 if you explicitly create a chat notebook with <span class=\"promptformatted\">File</span> > <span class=\"promptformatted\">New</span> > <span class=\"promptformatted\">Chat Notebook</span>.) As in Chat Notebooks, you use a chat break (with <span class=\"kbd\"><kbd>~</kbd></span>) to start a new chat within the same notebook. (In general, when you use a chat cell in an ordinary notebook to access Notebook Assistant, the assistant will see only material that occurs before the chat, and within the same chat block.)</p>\n<h2 id=\"also-introducing-llm-kit\">Also Introducing: LLM Kit</h2>\n<p>In mid-2023 we introduced <tt><a href=\"http://reference.wolfram.com/language/ref/LLMFunction.html\">LLMFunction</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/LLMSynthesize.html\">LLMSynthesize</a></tt> and related functions (as well as <tt><a href=\"http://reference.wolfram.com/language/ref/ChatEvaluate.html\">ChatEvaluate</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/ImageSynthesize.html\">ImageSynthesize</a></tt>, etc.) to let you access LLM functionality directly within the Wolfram Language. Until now these functions required connection to an external LLM provider. But along with Notebook Assistant we’re introducing today LLM Kit—which allows you to access all LLM functionality in the Wolfram Language directly through a subscription within your Wolfram Account. </p>\n<p>It’s all very easy: as soon as you enable your subscription, not only Notebook Assistant but also all LLM functionality will just work, going through our LLM service. (And, yes, Notebook Assistant is basically built on top of LLM Kit and the LLM service access it defines.)</p>\n<p>When you’ve enabled your Notebook Assistant + LLM Kit subscription, this is what you’ll see in the <span class=\"promptformatted\">Preferences</span> panel:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/12/sw12082024llmkitimg1.png' alt='Notebook Assistant + LLM Kit Preferences panel' title='Notebook Assistant + LLM Kit Preferences panel' width='616' height='392'/></p>\n<p>Our LLM service is primarily aimed at “human speed” LLM usage, in other words, things like responding to what you ask the Notebook Assistant. But the service also seamlessly supports programmatic things like <tt><a href=\"http://reference.wolfram.com/language/ref/LLMFunction.html\">LLMFunction</a></tt>. And for anything beyond small-scale uses of <tt><a href=\"http://reference.wolfram.com/language/ref/LLMFunction.html\">LLMFunction</a></tt>, etc. you’ll probably want to upgrade from the basic “Essentials” subscription level to the “Pro” level. And if you want to go “industrial scale” in your LLM usage, you can do that by explicitly purchasing <a href=\"https://www.wolfram.com/service-credits/\">Wolfram Service Credits</a>. </p>\n<p>Everything is set up to be easy if you use our Wolfram LLM service—and that’s what Notebook Assistant is based on. But for Chat Notebooks and programmatic LLM functionality, our Wolfram Language framework also supports connection to a wide range of external LLM service providers. You have to have your own external subscription to whatever external service you want to use. But once you have the appropriate access key you’ll be able to set things up so that you can pick that LLM provider interactively in Chat Notebooks, programmatically through <tt><a href=\"http://reference.wolfram.com/language/ref/LLMConfiguration.html\">LLMConfiguration</a></tt>, or in the <span class=\"promptformatted\">Preferences</span> panel. </p>\n<p>(By the way, we’re continually monitoring the performance of different LLMs on Wolfram Language generation; you can see weekly benchmark results at the <a href=\"https://www.wolfram.com/llm-benchmarking-project\">Wolfram LLM Benchmark Project website</a>—or get the data behind that from the <a href=\"https://datarepository.wolframcloud.com/\">Wolfram Data Repository</a>.)</p>\n<h2 id=\"opening-up-the-ability-to-go-computational\">Opening Up the Ability to “Go Computational”</h2>\n<p>There’s really never been anything quite like it before: a way of automatically taking what can be quite vague human thoughts and ideas, and making them crisp and structured—by expressing them computationally. And, yes, this is made possible now by the unexpectedly effective linguistic interface that LLMs give us. But ultimately what makes it possible is that the LLMs have a target: the <a href=\"https://wolfram.com/language/\">Wolfram Language</a> in all its breadth and depth. </p>\n<p>For me it’s an exciting moment. Because it’s a moment where everything we’ve been building these past four decades is suddenly much more broadly accessible. Expert users of Wolfram Language will be able to make use of all sorts of amazing nooks of functionality they never knew about. And people who’ve never used Wolfram Language before—or never even formulated anything computationally—will suddenly be able to do so.</p>\n<p>And it’s remarkable what kinds of things one can “make computational”. Let’s say you ask Wolfram Notebook Assistant to make up a story. Like pretty much anything today with LLMs inside, it’ll dutifully do that:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/Opening-Up-the-Ability-01-output-zoom.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12082024abilityimg1.png\" width='601' height='237'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>But how can one make something like this computational? Well, just ask Notebook Assistant:</p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image fullzoom\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/Opening-Up-the-Ability-02-output-zoom.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12082024abilityimg2.png\" width='430' height='838'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p id=\"examplegallery\"><a \nclass=\"magnific image\" alt=\"\" title=\"\" \n href=\"https://content.wolfram.com/sites/43/2024/12/Opening-Up-the-Ability-03-output-zoom.png\"><img \n src=\"https://content.wolfram.com/sites/43/2024/12/sw12082024abilityimg3.png\" width='619' height='177'\n loading=\"lazy\" alt=\"Click to enlarge\" title=\"Click to enlarge\"></a></p>\n<p>And what it does is rather remarkable: it uses Wolfram Language to create an interactive agent-based computational game version of the story! </p>\n<p>Computation is the great paradigm of our times. And the development of “computational X” for all X seems destined to be the future of pretty much every field. The whole tower of ideas and technology that is the modern Wolfram Language was built precisely to provide the computational language that is needed. But now Notebook Assistant is dramatically broadening access to that—making it possible to get “computational language superpowers” using just ordinary (and perhaps even vague) natural language. </p>\n<p>And even though I’ve now been living the computational language story for more than four decades Notebook Assistant keeps on surprising me with what it manages to make computational. It’s incredibly powerful to be able “go computational”. And even if you can’t imagine how it could work in what you’re doing, you should still just try it! Notebook Assistant may well surprise you—and in that moment show you a path to leverage the great power of the computational paradigm in ways that you’re never imagined. </p>\n<p><!--Version Release Stripe--></p>\n<p style=\"font-style: italic; color: #555;\">\n<style type=\"text/css\">\ndiv.bottomstripe { \n max-width:620px; \n margin-bottom:10px;\n background-color: #fff39a;\n border: solid 2px #ffd400;\n padding: 7px 10px 7px 10px;\n line-height: 1.2;}\n#blog .post_content .bottomstripe a,\n #blog .post_content .bottomstripe a:link,\n #blog .post_content .bottomstripe a:visited {\n font-family:\"Source Sans Pro\",Arial,Sans Serif; \n font-size:11pt; \n color:#aa0d00;}\n</style>\n<style type='text/css'>div.bottomstripe { background-color: #ff6516; border: solid 2px #ff6516; max-width: 100%; border-radius: 5px; } #blog .post_content .bottomstripe a, #blog .post_content .bottomstripe a:link, #blog .post_content .bottomstripe a:visited { color: white; }#blog #content .post_content a:hover { color: #ffe59b; }</style>\n<div class=\"bottomstripe\">\n<a href=\"https://www.wolfram.com/notebook-assistant-llm-kit/\"><strong>Subscribe to Wolfram Notebook Assistant now »</strong></a>\n</div>\n",

A Minimal Model for Biological Evolution and Other Adaptive Processes</a> [May 3, 2024].</em></p>\n<h2 id=\"even-more-from-an-extremely-simple-model\">Even More from an Extremely Simple Model</h2>\n<p><a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">A few months ago I introduced an extremely simple “adaptive cellular automaton” model</a> that seems to do remarkably well at capturing the essence of what’s happening in biological evolution. But over the past few months I’ve come to realize that the model is actually even richer and deeper than I’d imagined. And here I’m going to describe some of what I’ve now figured out about the model—and about the often-surprising things it implies for the foundations of biological evolution.</p>\n<p>The starting point for <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#the-model\">the model</a> is to view biological systems in abstract computational terms. We think of an organism as having a genotype that’s represented by a program, that’s then run to produce its phenotype. So, for example, the <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-1--how-do-simple-programs-behave\">cellular automaton</a> rules on the left correspond to a genotype which are then run to produce the phenotype on the right (starting from a “seed” of a single red cell):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg1.png' alt='' title='' width='475' height='394'> </div>\n</p></div>\n<p><span id=\"more-64272\"></span></p>\n<p>The key idea in our model is to adaptively evolve the genotype rules—say by making single “point mutations” to the list of outcomes from the rules:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg2.png' alt='' title='' width='210' height='78'> </div>\n</p></div>\n<p>At each step in the adaptive evolution we “accept” a mutation if it leads to a phenotype that has a higher—or at least equal—fitness relative to what we had before. So, for example, taking our fitness function to be the height (i.e. lifetime) of the phenotype pattern (with patterns that are infinite being assigned zero fitness), a sequence of (randomly chosen) adaptive evolution steps that go from the null rule to the rule above might be:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg3.png' alt='' title='' width='646' height='289'> </div>\n</p></div>\n<p>What if we make a different sequence of randomly chosen adaptive evolution steps? Here are a few examples of what happens—each in a sense “using a different idea” for how to achieve high fitness:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg4.png' alt='' title='' width='623' height='1014'> </div>\n</p></div>\n<p>And, yes, one can’t help but be struck by how “lifelike” this all looks—both in the complexity of these patterns, and in their diversity. But what is ultimately responsible for what we’re seeing? It’s long been a core question about biological evolution. Are the forms it produces the result of careful “sculpting” by the environment (and by the fitness functions it implies)—or are their most important features somehow instead a consequence of something more intrinsic and fundamental that doesn’t depend on details of fitness functions?</p>\n<p>Well, let’s say we pick a <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#other-adaptive-evolution-strategies:~:text=what%20about%20other%20kinds%20of%20objectives\">different fitness function</a>—for example, not the height of a phenotype pattern, but instead its width (or, more specifically, the width of its bounding box). Here are some results of adaptive evolution in this case:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg5.png' alt='' title='' width='581' height='776'> </div>\n</p></div>\n<p>And, yes, the patterns we get are now ones that achieve larger “bounding box width”. But somehow there’s still a remarkable similarity to what we saw with a rather different fitness function above. And, for example, in both cases, high fitness, it seems, is normally achieved in a complicated and hard-to-understand way. (The last pattern is a bit of an exception; as can also happen in biology, this is a case where for once there’s a “mechanism” in evidence that we can understand.) </p>\n<p>So what in the end is going on? As I discussed <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">when I introduced the model a few months ago</a>, it seems that the “dominant force” is not selection according to fitness functions, but instead the fundamental computational phenomenon of <a href=\"https://www.wolframscience.com/nks/p737--computational-irreducibility/\">computational irreducibility</a>. And what we’ll find here is that in fact what we see is, more than anything, the result of an interplay between the computational irreducibility of the process by which our phenotypes develop, and the computational boundedness of typical forms of fitness functions.</p>\n<p>The importance of such an interplay is something that’s very much come into focus as a result of our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a>. And indeed it now <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#mathematics-and-physics-have-the-same-foundations\">seems that the foundations</a> of both physics and mathematics are—more than anything—reflections of this interplay. And now it seems that’s true of biological evolution as well. </p>\n<p>In studying our model, there are many detailed phenomena we’ll encounter—most of which seem to have surprisingly direct analogs in actual biological evolution. For example, here’s what happens if we plot the behavior of the fitness function for our first example above over the course of the adaptive evolution process:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg6.png' alt='' title='' width='663' height='227'> </div>\n</p></div>\n<p>We see a sequence of “plateaus”, punctuated by jumps in fitness that reflect some “breakthrough” being made. In the picture, each red dot represents the fitness associated with a genotype that was tried. Many fall below the line of “best results so far”. But there are also plenty of red dots that lie right on the line. And these correspond to genotypes that yield the same fitness that’s already been achieved. But here—as in actual biological evolution—it’s important that there can be “<a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#:~:text=phenomena.%20There%20are-,%E2%80%9Cfitness%2Dneutral%E2%80%9D%20mutations,-that%20can%20%E2%80%9Cgo\">fitness-neutral evolution</a>”, where genotypes change, but the fitness does not. Usually such changes of genotype yield not just the same fitness, but also the exact same phenotype. Sometimes, however, there can be multiple phenotypes with the same fitness—and indeed this happens at one stage in the example here</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg7.png' alt='' title='' width='644' height='277'> </div>\n</p></div>\n<p>and at multiple stages in the second example we showed above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/12032024modelimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/12032024modelimg8.png' alt='' title='' width='646' height='236'> </div>\n</p></div>\n<h2 id=\"the-multiway-graph-of-all-possible-evolutions\">The Multiway Graph of All Possible Evolutions</h2>\n<p>In the previous section we saw examples of the results of a few particular random sequences of mutations. But what if we were to look at all possible sequences of mutations? As I <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#the-multiway-graph-of-all-possible-mutation-histories\">discussed when I introduced the model</a>, it’s possible to construct a <a href=\"https://www.wolframscience.com/nks/chap-5--two-dimensions-and-beyond#sect-5-6--multiway-systems\">multiway graph</a> that represents all possible mutation paths. Here’s what one gets for symmetric <em>k</em> = 2, <em>r</em> = 2 rules—starting from the null rule, and using height as a fitness function:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg1.png' alt='' title='' width='633' height='445'> </div>\n</p></div>\n<p>The way this graph is constructed, there are arrows from a given phenotype to all phenotypes with larger (finite) height that can be reached by a single mutation. </p>\n<p>But what if our fitness function is width rather than height? Well, then we get a different multiway graph in which arrows go to phenotypes not with larger height but instead with larger width:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg2.png' alt='' title='' width='606' height='375'> </div>\n</p></div>\n<p>So what’s really going on here? Ultimately one can think of there being an underlying graph (that one might call the “<a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#:~:text=graph%20of%20every%20possible%20way\">mutation graph</a>”) in which every edge represents a transformation between two phenotypes that can be achieved by a single mutation in the underlying genotype: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg3.png' alt='' title='' width='635' height='429'> </div>\n</p></div>\n<p>At this level, the transformations can go either way, so this graph is undirected. But the crucial point is that as soon as one imposes a fitness function, it defines a particular direction for each transformation (at least, each transformation that isn’t fitness neutral for this fitness function). And then if one starts, say, from the null rule, one will pick out a certain “evolution cone” subgraph of the original mutation graph.</p>\n<p>So, for example, with width as the fitness function, the subgraph one gets is what’s highlighted here:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg4.png' alt='' title='' width='495' height='278'> </div>\n</p></div>\n<p>There are several subtleties here. First, we simplified the multiway graph by doing <a href=\"https://reference.wolfram.com/language/ref/TransitiveReductionGraph.html\">transitive reduction</a> and drawing only the minimal edges necessary to define the connectivity of the graph. If we want to see all possible single-mutation transformations between phenotypes we need to do <a href=\"https://reference.wolfram.com/language/ref/TransitiveClosureGraph.html\">transitive completion</a>, in which case for the width fitness function the multiway graph we get is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg5.png' alt='' title='' width='611' height='336'> </div>\n</p></div>\n<p>But now there’s another subtlety. The edges in the multiway graph represent fitness-changing transformations. But there are also fitness-neutral transformations. And occasionally these can even lead to different (though equal-fitness) phenotypes, so that really each node in the graph above (say, the transitively reduced one) should sometimes be associated with multiple phenotypes</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg6.png' alt='' title='' width='667' height='347'> </div>\n</p></div>\n<p>which can “fitness neutrally” transform into each other, as in:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg7.png' alt='' title='' width='580' height='318'> </div>\n</p></div>\n<p>But even this isn’t the end of the subtleties. Fitness-neutral sets typically contain many genotypes differing by changes of rule cases that don’t affect the phenotype they produce. But it may be that just one or a few of these genotypes are “primed” to be able to generate another phenotype with just one additional mutation. Or, in other words, each node in the multiway graph above represents a whole class of genotypes “equivalent under fitness-neutral transformations”, and when we draw an arrow it indicates that some genotype in that class can be transformed by a single mutation to some genotype in the class associated with a different phenotype:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg8.png' alt='' title='' width='664' height='125'> </div>\n</p></div>\n<p>But beyond the subtleties, the key point is that particular fitness functions in effect just define particular orderings on the underlying mutation graph. It’s somewhat like choices of reference frames or families of simultaneity surfaces in physics. Different choices of fitness function in effect define different ways in which the underlying mutation graph can be “navigated” by evolution over the course of time.</p>\n<p>As it happens, the results are not so different between height and width fitness functions. Here’s a combined multiway graph, indicating transformations variously allowed by these different fitness functions:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg9.png' alt='' title='' width='623' height='385'> </div>\n</p></div>\n<p>Homing in on a small part of this graph, we see that there are different “flows” associated with maximizing height and maximizing width: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024multiwayimg10.png' alt='' title='' width='297' height='309'> </div>\n</p></div>\n<p>With a single fitness function that for any two phenotypes systematically treats one phenotype as fitter than another, the multiway graph must always define a definite flow. But as soon as one considers changing fitness functions in the course of evolution, it’s possible to get cycles in the multiway graph, as in the example above—so that, in effect, “evolution can repeat itself”. </p>\n<h2 id=\"fitness-functions-based-on-aspect-ratio\">Fitness Functions Based on Aspect Ratio</h2>\n<p>We’ve looked at fitness functions based on maximizing height and on maximizing width. But what if we try to combine these? Here’s a plot of the widths and heights of all phenotypes that occur in the symmetric <em>k</em> = 2, <em>r</em> = 2 case we studied above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg1.png' alt='' title='' width='636' height='404'> </div>\n</p></div>\n<p>We could imagine a variety of ways to define “fitness frontiers” here. But as a specific example, let’s consider fitness functions that are based on trying to achieve specific aspect ratios—i.e. phenotypes that are as close as possible to a particular constant-aspect-ratio line in the plot above. </p>\n<p>With the symmetric <em>k</em> = 2, <em>r</em> = 2 rules we’re using here, only a certain set of aspect ratios can ever be obtained:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessBimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg2.png' alt='' title='' width='638' height='36'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg3.png' alt='' title='' width='638' height='76'> </div>\n</p></div>\n<p>The corresponding phenotypes (with their aspect ratios) are:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg4.png' alt='' title='' width='622' height='357'> </div>\n</p></div>\n<p>As we change the aspect ratio that we’re trying to achieve, the evolution multiway graph will change:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessBimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024fitnessAimg5.png' alt='' title='' width='646' height='626'> </div>\n</p></div>\n<p>In all cases we’re starting from the null rule. For target aspect ratio 1.0 this rule itself already achieves that aspect ratio—so the multiway graph in that case is trivial. But in general, different aspect ratios yield evolution multiway graphs that are different subgraphs of the complete mutation graph we saw above. </p>\n<p>So if we follow all possible paths of evolution, how close can we actually get to any given target aspect ratio? This plot shows what final aspect ratios can be achieved as a function of target aspect ratio:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12052024fitnessBimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12052024fitnessBimg6.png' alt='' title='' width='427' height='276'> </div>\n</p></div>\n<p>And in a sense this is a summary of the effect of “developmental constraints” for “adaptive cellular automaton organisms” like this. If there were no constraints then for every target aspect ratio it’d be possible to get an “organism” with that aspect ratio—so in the plot there’d be a point lying on the red line. But in actuality the process of cellular automaton growth imposes constraints—that in particular allows only certain phenotypes, with certain aspect ratios, to exist. And beyond that, which phenotypes can actually be reached by adaptive evolution depends on the evolution multiway graph, with “different turns” on the graph leading to different fitness (i.e. different aspect ratio) phenotypes.</p>\n<p>But what the plot above shows overall is that for a certain range of target aspect ratios, adaptive evolution is successfully able to get at least close to those aspect ratios.

There are a few examples where new rule cases show up only at the end, as if a new “incrementally engineered” pattern was being “grafted on at the end”.

And somehow those few “tweaks” lead to higher fitness—even though there’s no obvious reason why, and no obvious way to predict where they should be.</p>\n<p>It’s interesting to compare this with actual biology, where it’s pretty common to see what appear to be “random gratuitous changes” between apparently very similar organisms. (And, yes, this can lead to all sorts of problems in things like comparing toxicity or drug effectiveness in model animals versus humans.) </p>\n<p>There are many ways to consider quantitatively characterizing how “rule utilization” builds up.

We might have expected that different fitness functions would cleanly select visibly different parts of morphospace. But at least with our machine-learning-based way of laying out morphospace that’s not what we’re seeing. And it seems likely that this is actually a general result—and that there is no layout procedure that can make any “easy to describe” fitness function “geometrically simple” in morphospace. And once again, this is presumably a consequence of underlying computational irreducibility—and to the fact that we can’t expect any morphospace layout procedure to be able to provide a way to “untangle the irreducibility” that will work for all fitness functions.</p>\n<h2 id=\"probabilities-and-the-time-course-of-evolution\">Probabilities and the Time Course of Evolution</h2>\n<p>In what we’ve done so far, we’ve mostly been concerned with things like what sequences of phenotypes can ever be produced by adaptive evolution. But in making analogies to actual biological evolution—and particularly to how it’s captured in the fossil record—it’s also relevant to discuss time, and to ask not only what phenotypes can be produced, but also when, and how frequently. </p>\n<p>For example, let’s assume there’s a constant rate of point mutations in time. Then starting from a given rule (like the null rule) there’ll be a certain rate at which transitions to other rules occur. Some of these transitions will lead to rules that are selected out. Others will be kept, but will yield the same phenotype. And still others will lead to transitions to different phenotypes.</p>\n<p>We can represent this by a “phenotype transition diagram” in which the thickness of each outgoing edge from a given phenotype indicates the fraction of all possible mutations that lead to the transition associated with that edge: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12052024probabilitiesXimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12052024probabilitiesBimg1.png' alt='' title='' width='625' height='447'> </div>\n</p></div>\n<p>Gray self-loops in this diagram represent transitions that lead back to the same phenotype (because they change cases in the rule that don’t matter).

Things happen quickly down at the level of individual mutation and selection events—but the fitness function defines overall “goals” for the system that in effect change only slowly. (It’s a bit like a fluid where there are fast molecular-scale processes, but typically slow changes of macroscopic parameters like pressure.) </p>\n<p>But if the fitness function defines a goal, how well does the system manage to meet it? Here’s a comparison between an aspect ratio goal (here, linearly increasing) and the distribution of actual aspect ratios achieved, with the darker curve indicating the mean aspect ratio obtained by a weighted average over phenotypes, and the lighter blue area indicating the standard deviation:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12042024macroscopicimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12042024macroscopicimg5.png' alt='' title='' width='409' height='257'> </div>\n</p></div>\n<p>And, yes, as we might have expected from earlier results, the system doesn’t do particularly well at achieving the goal. Its behavior is ultimately not “well sculpted” by the forces of a fitness function; instead it is mostly dominated by the intrinsic (computationally irreducible) dynamics of the underlying adaptive evolution process.</p>\n<p>One important thing to note however is that our results depend on the value of a parameter: essentially the rate at which underlying mutations occur relative to the rate of change of the fitness function. In the picture above 5000 mutations occur over the time the fitness function goes from minimum to maximum value. This is what happens if we change the number of mutations that occur (or, in effect, the “mutation rate”):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12042024macroscopicimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12042024macroscopicimg6.png' alt='' title='' width='603' height='145'> </div>\n</p></div>\n<p>Generally—and not surprisingly—adaptive evolution does better at achieving the target when the mutation rate is higher, though in both the cases shown here, nothing gets terribly close to the target.</p>\n<p>In their general character our results here seem reminiscent of what one might expect in typical studies of continuum systems, say based on differential equations. And indeed one can imagine that there might be “continuum equations of adaptive evolution” that govern situations like the ones we’ve seen here. But it’s important to understand that it’s far from self evident that this is possible. Because underneath everything is a multiway evolution graph with a definite and complicated structure. And one might think that the details of this structure would matter to the overall “continuum evolution process”. And indeed sometimes they will. </p>\n<p>But—as we have seen throughout our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a>—underlying computational irreducibility leads to a certain inevitable simplicity when looking at phenomena perceived by <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">computationally bounded observers</a>. And we can expect that something similar can happen with biological evolution (and indeed <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">adaptive evolution in general</a>). Assuming that our fitness functions (and their process of change) are computationally bounded, then we can expect that their “aggregate effects” will follow comparatively simple laws—which we can perhaps think of as laws for the “flow of evolution” in response to external input. </p>\n<h2 id=\"can-evolution-be-reversed\">Can Evolution Be Reversed?</h2>\n<p>In the previous section we saw that with different fitness functions, different time series of phenotypes appear, with some phenotypes, for example, sometimes “going extinct”.

But could we perhaps construct a fitness function for the reverse graph that will successfully corral the evolution process to precisely retrace the steps of the forward graph? </p>\n<p>In general, this isn’t something we can expect to be able to do. Because to do so would in effect require “breaking the computational irreducibility” of the system. It would require having a fitness function that can in essence predict every detail of the evolution process—and in so doing be in a position to direct it. But to achieve this, the fitness function would in a sense have to be computationally as sophisticated as the evolution process itself. </p>\n<p>It’s a variant of an argument we’ve used several times here. Realistic fitness functions are computationally bounded (and in practice often very coarse). And that means that they can’t expect to match the computational irreducibility of the underlying evolution process. </p>\n<p>There’s an analogy to the <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">Second Law of thermodynamics</a>. Just as the microscopic collisions of individual molecules are in principle easy to reverse, so potentially are individual transitions in the evolution graph. But putting many collisions or many transitions together leads to a process that is computationally sophisticated enough that the fairly coarse means at our disposal can’t “decode” and reverse it. </p>\n<p>Put another way, there is in practice a certain inevitable irreversibility to both molecular dynamics and biological evolution. Yes, with enough computational effort—say carefully controlling the fitness function for every individual organism—it might in principle be possible to precisely “reverse evolution”. But in practice the kinds of fitness functions that exist in nature—or that one can readily set up in a lab—are computationally much too weak. And as a result one can’t expect to be able to get evolution to precisely retrace its steps.</p>\n<h2 id=\"random-or-selected-can-one-tell\">Random or Selected? Can One Tell?</h2>\n<p>Given only a genotype, is there a way to tell whether it’s “just random” or whether it’s <a href=\"https://writings.stephenwolfram.com/2018/01/showing-off-to-the-universe-beacons-for-the-afterlife-of-our-civilization/\">actually the result of some long and elaborate process</a> of adaptive evolution? From the genotype one can in principle use the rules it defines to “grow” the corresponding phenotype—and then look at whether it has an “unusually large” fitness. But the question is whether it’s possible to tell anything directly from the genotype, without going through the computational effort of generating the phenotype.</p>\n<p>At some level it’s like asking, whether, say, from a cellular automaton rule, one can predict the ultimate behavior of the cellular automaton. And a core consequence of computational irreducibility is that one can’t in general expect to do this. Still, one might imagine that one could at least make a “reasonable guess” about whether a genotype is “likely” to have been chosen “purely randomly” or to have been “carefully selected”. </p>\n<p>To explore this, we can look at the genotypes for symmetric <em>k</em> = 2, <em>r</em> = 2 rules, say ordered by their lifetime-based fitness—with black and white here representing “required” rule cases, and gray representing undetermined ones (which can all independently be either black or white):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024randomimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024randomimg1.png' alt='' title='' width='285' height='602'> </div>\n</p></div>\n<p>On the right is a summary of how many white, black and undetermined (gray) outcomes are present in each genotype. And as we have seen several times, to achieve high fitness all or almost all of the outcomes must be determined—so that in a sense all or almost all of the genome is “being used”. But we still need to ask whether, given a certain actual pattern of outcomes, we can successfully guess whether or not a genotype is the result of selection.</p>\n<p>To get more of a sense of this, we can look at plots of the probabilities for different outcomes for each case in the rule, first (trivially) for all combinatorially possible genotypes, then for all genotypes that give viable (i.e. in our case, finite-lifetime) phenotypes, and then for “selected genotypes”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12032024randomimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12032024randomimg2.png' alt='' title='' width='479' height='167'> </div>\n</p></div>\n<p>Certain cases are always completely determined for all viable genomes—but rather trivially so, because, for example, if <img style=\"margin-bottom: -2px\" loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/randomboxrow.png' alt='' title='' width='73' height='13'/> then the pattern generated will expand at maximum speed forever, and so cannot have a finite lifetime. </p>\n<p>So what happens for all <em>k</em> = 2, <em>r</em> = 2 rules?

But what’s true in general? Is there something that can be determined with bounded computational effort (i.e. without explicitly computing phenotypes and their fitnesses) that gives a good estimate of whether a genome is selected? There are good reasons to believe that computational irreducibility will make this impossible. </p>\n<p>It’s a different story, of course, if one’s given a “fully computed” phenotype.

So now we can ask: can we evolve this evolution? Or, in other words, can we apply adaptive evolution to systems like multiway Turing machines?</p>\n<p>As an example, let’s assume that we make single point mutation changes to just one case in a multiway Turing machine rule:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12052024machinesimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12052024machinesimg4.png' alt='' title='' width='223' height='283'> </div>\n</p></div>\n<p>Many multiway Turing machines won’t halt, or at least won’t halt on all their branches. But for our fitness function let’s assume we require multiway Turing machines to halt on all branches (or at least go into loops that revisit the same states), and then let’s take the fitness to be the <a href=\"https://bulletins.wolframphysics.org/2021/02/multiway-turing-machines/#the-halting-problem-and-busy-beavers\" target=\"_blank\" rel=\"noopener\">total number of nodes in the multiway graph when everything has halted</a>. (And, yes, this is a direct generalization of our lifetime fitness function for ordinary Turing machines.) </p>\n<p>So with this setup here are some examples of sequences of “breakthroughs” in adaptive evolution processes: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12122024C2Cupdateimg5_copy.txt' data-c2c-type='text/html'> <img src='https://content.wolfram.com/sites/43/2024/12/sw12052024machinesimg5.png' alt='Breakthrough sequences' title='Breakthrough sequences' width='620' height='1003'/> </div>\n</p></div>\n<p>But what about looking at all possible paths of evolution for multiway Turing machines? Or, in other words, what about making a multiway graph of the evolution of multiway Turing machines?</p>\n<p>Here’s an example of what we get by doing this (showing at each node just a single example of a fitness-neutral set):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/12/sw12052024machinesimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/12/sw12052024machinesimg6.png' alt='' title='' width='651' height='459'> </div>\n</p></div>\n<p>So what’s really going on here? We’ve got a multiway graph of multiway graphs. But it’s worth understanding that the inner and outer multiway graphs are a bit different. The outer one is effectively a <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">rulial multiway graph</a>, in which different parts correspond to following different rules. The inner one is effectively a branchial multiway graph, in which different parts correspond to different ways of applying a particular rule. Ultimately, though, we can at least in principle expect to encode branchial transformations as rulial ones, and vice versa. </p>\n<p>So we can think of the adaptive evolution of multiway Turing machines as a first step in exploring “higher-order evolution”: the evolution of evolution, etc. And ultimately in exploring inevitable limits of recursive evolution in the ruliad—and how these might relate to the formation of observers in the ruliad.</p>\n<h2 id=\"some-conclusions\">Some Conclusions</h2>\n<p>What does all this mean for the foundations of biological evolution? First and foremost, it reinforces the idea of <a href=\"https://www.wolframscience.com/nks/chap-8--implications-for-everyday-systems#sect-8-5--fundamental-issues-in-biology\">computational irreducibility as a dominant force in biology</a>. One might have imagined that what we see in biology must have been “carefully sculpted” by fitness constraints (say imposed by the environment). But what we’ve found here suggests that instead much of what we see is actually just a direct reflection of computational irreducibility. And in the end, more than anything else, what biological evolution seems to be doing is to “recruit” lumps of irreducible computation, and set them up so as to achieve “fitness objectives”.</p>\n<p>It is, as I recently discovered, very similar to <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">what happens in machine learning</a>. And in both cases this picture implies that there’s a limit to the kind of explanations one can expect to get. If one asks why something has the form it does, the answer will often just be: “because that’s the lump of irreducible computation that happened to be picked up”. And there isn’t any reason to think that there’ll be a “narrative explanation” of the kind one might hope for in traditional science.</p>\n<p>The simplicity of models makes it possible to study not just particular possible paths of adaptive evolution, but complete multiway graphs of all possible paths. And what we’ve seen here is that fitness functions in effect define a kind of <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/foliations-and-coordinates-on-causal-graphs\" target=\"_blank\" rel=\"noopener\">traversal order or (roughly) foliation for such multiway graphs</a>. If such foliations could be arbitrarily complex, then they could potentially pick out specific outcomes for evolution—in effect successfully “sculpting biology” through the details of natural selection and fitness functions. </p>\n<p>But the point is that fitness functions and resulting foliations of multiway evolution graphs don’t get arbitrarily complex. And even as the underlying processes by which phenotypes develop are full of computational irreducibility, the fitness functions that are applied are computationally bounded. And in effect the complexity that is perhaps the single most striking immediate feature of biological systems is therefore a consequence of the interplay between the computational boundedness of selection processes, and the computational irreducibility of underlying processes of growth and development. </p>\n<p>All of this relies on the fundamental idea that biological evolution—and biology—are at their core computational phenomena. And given this interpretation, there’s then a remarkable unification that’s emerging. </p>\n<p>It begins with the <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">ruliad</a>—the abstract object corresponding to the entangled limit of all possible computational processes. We’ve talked about the ruliad as the ultimate foundation for physics, and for <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/\">mathematics</a>. And we now see that we can think of it as the ultimate foundation for biology too. </p>\n<p>In physics what’s crucial is that <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">observers like us “parse” the ruliad</a> in certain ways—and that these ways lead us to have a perception of the ruliad that follows core known laws of physics. And similarly, when observers like us do mathematics, we can think of ourselves as “extracting that mathematics” from the way we parse the ruliad. And now what we’re seeing is that biology emerges because of the way selection from the environment, etc. “parses” the ruliad. </p>\n<p>And what makes this view powerful is that we have to assume surprisingly little about how selection works to still be able to deduce important things about biology. In particular, if we assume that the selection operates in a computationally bounded way, then just from the inevitable underlying computational irreducibility “inherited” from the ruliad, we immediately know that biology must have certain features. </p>\n<p>In physics, the <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">Second Law of thermodynamics arises from the interplay</a> of underlying computational irreducibility of mechanical processes involving many particles or other objects, and our computational boundedness as observers. We have the impression that “randomness is increasing” because as computationally bounded observers we can’t “decrypt” the underlying computational irreducibility. </p>\n<p>What’s the analog of this in biology? Much as we can’t expect to “say what happens” in a system that follows the Second Law, so we can’t expect to “explain by selection” what happens in a biological system. Or, put another way, much of what we see in biology is just the way it is because of computational irreducibility—and try as we might it won’t be “explainable” by some fitness criterion that we can describe. </p>\n<p>But that doesn’t mean that we can’t expect to deduce “general laws of biology”, much as there are general laws about gases whose detailed structure follows the Second Law. And in what we’ve done here we can begin to see some hints of what those general laws might look like.</p>\n<p>They’ll be things like bulk statements about possible paths of evolution, and the effect of changing the constraints on them—a bit like laws of fluid mechanics but now applied to the rulial space of possible genotypes. But if there’s one thing that’s clear it’s that the minimal model we’ve developed of biological evolution has remarkable richness and potential. In the past it’s been possible to say things about what amounts to the pure combinatorics of evolution; now we can start talking in a structured way about what evolution actually does. And in doing this we go in the direction of finally giving biology a foundation as a theoretical science. </p>\n<h2 id='theres-so-much-more-to-study'>There’s So Much More to Study!</h2>\n<p>Even though this is my second long piece about my minimal model of biological evolution, I’ve barely scratched the surface of what can be done with it. First and foremost there are many detailed connections to be made with actual phenomena that have been observed—or could be observed—in biology. But there are also many things to be investigated directly about the model itself—and in effect much ruliology to be done on it. And what’s particularly notable is how accessible a lot of that ruliology is. (And, yes, you can click any picture here to get the Wolfram Language code that generates it.) What are some obvious things to do? Here are few. Investigate other fitness functions. Other rule spaces. Other initial conditions. Other evolution strategies. Investigate evolving both rules and initial conditions. Investigate different kinds of changes of fitness functions during evolution. Investigate the effect of having a much larger rule space. Investigate robustness (or not) to perturbations. </p>\n<p>In what I’ve done here, I’ve effectively aggregated identical genotypes (and phenotypes). But one could also investigate what happens if one in effect “traces every individual organism”. The result will be abstract structures that generalize the multiway systems we’ve shown here—and that are associated with higher levels of abstract formalism capable of describing phenomena that in effect go “below species”.</p>\n<p><span class=\"Subsubsection\"><a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#historical-notes\">For historical notes see here »</a></span></p>\n<h2 id=\"thanks\" style='font-size:1.2rem'>Thanks</h2>\n<p style='font-size:90%'>Thanks to Wolfram Institute fellows Richard Assar and Nik Murzin for their help, as well as to the supporters of the new Wolfram Institute initiative in theoretical biology.

But what actually is it? In traditional scientific accounts it’s often represented as some kind of coordinate much like space (though a coordinate that for some reason is always systematically increasing for us). But while this may be a useful mathematical description, it’s not telling us anything about what time in a sense “intrinsically is”. </p>\n<p>We get closer as soon as we start thinking in computational terms. Because then it’s natural for us to think of successive states of the world as being computed one from the last by the progressive application of some computational rule. And this suggests that we can identify the progress of time with the “progressive doing of <nobr id=\"link-test\"> computation</nobr> by the universe”. </p>\n<p>But does this just mean that we are replacing a “time coordinate” with a “computational step count”? No. Because of the phenomenon of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>. With the traditional mathematical idea of a time coordinate one typically imagines that this coordinate can be “set to any value”, and that then one can immediately calculate the state of the system at that time. But computational irreducibility implies that it’s not that easy. Because it says that there’s often essentially no better way to find what a system will do than by explicitly tracing through each step in its evolution.<span id=\"more-63438\"></span></p>\n<p>In the pictures on the left there’s computational reducibility, and one can readily see what state will be after any number of steps <em>t</em>. But in the pictures on the right there’s (presumably) computational irreducibility, so that the only way to tell what will happen after <em>t</em> steps is effectively to run all those steps:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/10/sw10082024timeBimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/10/sw10082024timeBimg1.png' alt='' title='' width='642' height='178'> </div>\n</p></div>\n<p>And what this implies is that there’s a certain robustness to time when viewed in these computational terms. There’s no way to “jump ahead” in time; the only way to find out what will happen in the future is to go through the irreducible computational steps to get there. </p>\n<p>There are simple idealized systems (say with purely periodic behavior) where there’s computational reducibility, and where there isn’t any robust notion of the progress of time. But the point is that—as the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> implies—our universe is inevitably full of computational irreducibility which in effect defines a robust notion of the progress of time.</p>\n<h2 id=\"the-role-of-the-observer\">The Role of the Observer</h2>\n<p>That time is a reflection of the progress of computation in the universe is an important starting point. But it’s not the end of the story. For example, here’s an immediate issue. If we have a computational rule that determines each successive state of a system it’s at least in principle possible to know the whole future of the system. So given this why then do we have the experience of the future only “unfolding as it happens”?</p>\n<p>It’s fundamentally because of the way <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">we are as observers</a>. If the underlying system is computationally irreducible, then to work out its future behavior requires an irreducible amount of computational work. But it’s a core feature of observers like us that we are computationally bounded. So we can’t do all that irreducible computational work to “know the whole future”—and instead we’re effectively stuck just doing computation alongside the system itself, never able to substantially “jump ahead”, and only able to see the future “progressively unfold”.</p>\n<p>In essence, therefore, we experience time because of the interplay between our computational boundedness as observers, and the computational irreducibility of underlying processes in the universe. If we were not computationally bounded, we could “perceive the whole of the future in one gulp” and we wouldn’t need a notion of time at all. And if there wasn’t underlying computational irreducibility there wouldn’t be the kind of “progressive revealing of the future” that we associate with our experience of time.</p>\n<p>A notable feature of our everyday perception of time is that it seems to “flow only in one direction”—so that for example it’s generally much easier to remember the past than to predict the future. And this is closely related to the Second Law of thermodynamics, which (as <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">I’ve argued at length elsewhere</a>) is once again a result of the interplay between underlying computational irreducibility and our computational boundedness. Yes, the microscopic laws of physics may be reversible (and indeed if our system is simple—and computationally reducible—enough of this reversibility may “shine through”). But the point is that computational irreducibility is in a sense a much stronger force.</p>\n<p>Imagine that we prepare a state to have orderly structure. If its evolution is computationally irreducible then this structure will effectively be “encrypted” to the point where a computationally bounded observer can’t recognize the structure. Given underlying reversibility, the structure is in some sense inevitably “still there”—but it can’t be “accessed” by a computationally bounded observer. And as a result such an observer will perceive a definite flow from orderliness in what is prepared to disorderliness in what is observed. (In principle one might think it should be possible to set up a state that will “behave antithermodynamically”—but the point is that to do so would require predicting a computationally irreducible process, which a computationally bounded observer can’t do.)</p>\n<p>One of the longstanding confusions about the nature of time has to do with its “mathematical similarity” to space. And indeed ever since the early days of relativity theory it’s seemed convenient to talk about “spacetime” in which notions of space and time are bundled together.</p>\n<p>But in our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> that’s not at all how things fundamentally work. At the lowest level the state of the universe is <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#what-is-space\">represented by a hypergraph</a> which captures what can be thought of as the “spatial relations” between discrete “atoms of space”. <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#time\">Time then corresponds</a> to the progressive rewriting of this hypergraph.</p>\n<p>And in a sense the “atoms of time” are the elementary “rewriting events” that occur. If the “output” from one event is needed to provide “input” to another, then we can think of the first event as preceding the second event in time—and the events as being “timelike separated”. And in general we can construct a <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#the-graph-of-causal-relationships\">causal graph</a> that shows the dependencies between different events. </p>\n<p>So how does this relate to time—and spacetime? As we’ll discuss below, our everyday experience of time is that it follows a single thread. And so we tend to want to “parse” the causal graph of elementary events into a series of slices that we can view as corresponding to “successive times”. As in <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#deriving-special-relativity\">standard relativity theory</a>, there typically isn’t a unique way to assign a sequence of such “simultaneity surfaces”, with the result that there are different “reference frames” in which the identifications of space and time are different. </p>\n<p>The complete causal graph bundles together what we usually think of as space with what we usually think of as time. But ultimately the progress of time is always associated with some choice of successive events that “computationally build on each other”. And, yes, it’s more complicated because of the possibilities of different choices. But the basic idea of the progress of time as “the doing of computation” is very much the same. (In a sense time represents “computational progress” in the universe, while space represents the “layout of its data structure”.)</p>\n<p>Very much as in the derivation of the Second Law (or of fluid mechanics from molecular dynamics), the <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#general-relativity-and-gravity\">derivation of Einstein’s equations</a> for the large-scale behavior of spacetime from the underlying causal graph of hypergraph rewriting depends on the fact that we are computationally bounded observers. But even though we’re computationally bounded, we still have to “have something going on inside”, or we wouldn’t record—or sense—any “progress in time”.</p>\n<p>It seems to be the essence of observers like us—as captured in my <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">recent Observer Theory</a>—that we equivalence many different states of the world to derive our internal perception of “what’s going on outside”. And at some rough level we might imagine that we’re sensing time passing by the rate at which we add to those internal perceptions. If we’re not adding to the perceptions, then in effect time will stop for us—as happens if we’re asleep, anesthetized or dead. </p>\n<p>It’s worth mentioning that in some extreme situations it’s not the internal structure of the observer that makes perceived time stop; instead it’s the underlying structure of the universe itself. As we’ve mentioned, the “progress of the universe” is associated with successive rewriting of the underlying hypergraph. But when there’s been “too much activity in the hypergraph” (which physically corresponds roughly to too much energy-momentum), one can end up with a situation in which “there are no more rewrites that can be done”—so that in effect some part of the universe can no longer progress, <a href=\"https://www.wolframphysics.org/technical-introduction/potential-relation-to-physics/cosmology-expansion-and-singularities\" target=\"_blank\" rel=\"noopener\">and “time stops” there</a>. It’s analogous to what happens at a spacelike singularity (normally associated with a black hole) in traditional general relativity. But now it has a very direct computational interpretation: one’s reached a “fixed point” at which there’s no more computation to do. And so there’s no progress to make in time.</p>\n<h2 id=\"multiple-threads-of-time\">Multiple Threads of Time</h2>\n<p>Our strong human experience is that time progresses as a single thread. But now our <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#the-inevitability-of-quantum-mechanics\">Physics Project suggests</a> that at an underlying level time is actually in effect multithreaded, or, in other words, that there are many different “paths of history” that the universe follows. And it is only because of the way we as observers sample things that we experience time as a single thread. </p>\n<p>At the level of a particular underlying hypergraph the point is that there may be many different updating events that can occur, and each sequence of such updating event defines a different “path of history”. We can summarize all these paths of history in a multiway graph in which we merge identical states that arise:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/10/sw10082024timeAimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/10/sw10082024timeAimg2.png' alt='' title='' width='194' height='242'> </div>\n</p></div>\n<p>But given this underlying structure, why is it that we as observers believe that time progresses as a single thread? It all has to do with the notion of <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/the-concept-of-branchial-graphs/\" target=\"_blank\" rel=\"noopener\">branchial space</a>, and our presence within branchial space. The presence of many paths of history is what leads to quantum mechanics; the fact that we as <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/#the-case-of-quantum-mechanics\">observers ultimately perceive just one path</a> is associated with the traditionally-quite-mysterious phenomenon of “measurement” in quantum mechanics. </p>\n<p>When we talked about causal graphs above, we said that we could “parse” them as a series of “spacelike” slices corresponding to instantaneous “states of space”—represented by spatial hypergraphs. And by analogy we can similarly imagine breaking multiway graphs into “instantaneous slices”. But now these slices don’t represent states of ordinary space; instead they represent states of what we call branchial space.</p>\n<p>Ordinary space is “knitted together” by updating events that have causal effects on other events that can be thought of as “located at different places in space”. (Or, said differently, space is knitted together by the overlaps of the elementary light cones of different events.) Now we can think of branchial space as being “knitted together” by updating events that have effects on events that end up on different branches of history. </p>\n<p>(In general there is a close analogy between ordinary space and branchial space, and we can define a multiway causal graph that includes both “spacelike” and “branchlike” directions—with the branchlike direction supporting not light cones but what we can call entanglement cones.)</p>\n<p>So how do we as observers parse what’s going on? A key point is that we are inevitably part of the system we’re observing. So the branching (and merging) that’s going on in the system at large is also going on in us. So that means we have to ask how a “branching mind” will perceive a branching universe. Underneath, there are lots of branches, and lots of “threads of history”. And there’s lots of computational irreducibility (and even what we can call <a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-\nmulticomputational-systems/#humanizing-multicomputational-processes\">multicomputational irreducibility</a>). But computationally bounded observers like us have to equivalence most of those details to wind up with something that “fits in our finite minds”. </p>\n<p>We can make an analogy to what happens in a gas. Underneath, there are lots of molecules bouncing around (and behaving in computationally irreducible ways). But observers like us are big compared to molecules, and (being computationally bounded) we don’t get to perceive their individual behavior, but only their aggregate behavior—from which we extract a thin set of computationally reducible “fluid-dynamics-level” features. </p>\n<p>And it’s basically the same story with the underlying structure of space. Underneath, there’s an elaborately changing network of discrete atoms of space. But as large, computationally bounded observers we can only sample aggregate features in which many details have been equivalenced, and in which space tends to seem continuous and describable in basically computationally reducible ways. </p>\n<p>So what about branchial space? Well, it’s basically the same story. Our minds are “big”, in the sense that they span many individual branches of history. And they’re computationally bounded so they can’t perceive the details of all those branches, but only certain aggregated features. And in a first approximation what then emerges is in effect a single aggregated thread of history. </p>\n<p>With sufficiently careful measurements we can sometimes see “quantum effects” in which multiple threads of history are in evidence. But at a direct human level we always seem to aggregate things to the point where what we perceive is just a single thread of history—or in effect a single thread of progression in time.</p>\n<p>It’s not immediately obvious that any of these “aggregations” will work. It could be that important effects we perceive in gases would depend on phenomena at the level of individual molecules. Or that to understand the large-scale structure of space we’d continually be having to think about detailed features of atoms of space. Or, similarly, that we’d never be able to maintain a “consistent view of history”, and that instead we’d always be having to trace lots of individual threads of history. </p>\n<p>But the key point is that for us to stay as computationally bounded observers we have to pick out only features that are computationally reducible—or in effect boundedly simple to describe. </p>\n<p>Closely related to our computational boundedness is the <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/\">important assumption</a> we make that we as observers have a certain persistence. At every moment in time, we are made from different atoms of space and different branches in the multiway graph. Yet we believe we are still “the same us”. And the crucial physical fact (that has to be derived in our model) is that in ordinary circumstances there’s no inconsistency in doing this.</p>\n<p>So the result is that even though there are many “threads of time” at the lowest level—representing many different “quantum branches”—observers like us can (usually) successfully still view there as being a single consistent perceived thread of time.</p>\n<p>But there’s another issue here. It’s one thing to say that a single observer (say a single human mind or a single measuring device) can perceive history to follow a single, consistent thread. But what about different human minds, or different measuring devices? Why should they perceive any kind of consistent “objective reality”?</p>\n<p>Essentially the answer, I think, is that they’re all sufficiently nearby in branchial space. If we think about physical space, observers in different parts of the universe will clearly “see different things happening”. The “laws of physics” may be the same—but what star (if any) is nearby will be different. Yet (at least for the foreseeable future) for all of us humans it’s always the same star that’s nearby. </p>\n<p>And so it is, presumably, in branchial space. There’s some small patch in which we humans—with our shared origins—exist. And it’s presumably because that patch is small relative to all of branchial space that all of us perceive a consistent thread of history and a common objective reality. </p>\n<p>There are many subtleties to this, many of which aren’t yet fully worked out. In physical space, we know that effects can in principle spread at the speed of light. And in branchial space the analog is that effects can spread at the maximum entanglement speed (whose value we don’t know, though it’s <a href=\"https://www.wolframphysics.org/technical-introduction/potential-relation-to-physics/units-and-scales/\" target=\"_blank\" rel=\"noopener\">related by Planck unit conversions to the elementary length and elementary time</a>). But in maintaining our shared “objective” view of the universe it’s crucial that we’re not all going off in different directions at the speed of light. And of course the reason that doesn’t happen is that we don’t have zero mass. And indeed presumably nonzero mass is a critical part of being observers like us. </p>\n<p>In our Physics Project it’s roughly the density of events in the hypergraph that determines the density of energy (and mass) in physical space (with their associated gravitational effects). And similarly it’s roughly the density of events in the multiway graph (or in branchial graph slices) that determines the density of action—the relativistically invariant analog of energy—in branchial space (with its associated effects on quantum phase). And though it’s not yet completely clear how this works, it seems likely that once again when there’s mass, effects don’t just “go off at the maximum entanglement speed in all directions”, but instead stay nearby.</p>\n<p>There are definitely connections between “staying at the same place”, believing one is persistent, and being computationally bounded. But these are what seem necessary for us to have our typical view of time as a single thread. In principle we can imagine observers very different from us—say with minds (like the inside of an idealized quantum computer) capable of experiencing many different threads of history. But the Principle of Computational Equivalence suggests that there’s a high bar for such observers. They need not only to be able to deal with computational irreducibility but also multicomputational irreducibility, in which one includes both the process of computing new states, and the process of equivalencing states. </p>\n<p>And so for observers that are “anything like us” we can expect that once again time will tend to be as we normally experience it, following a single thread, consistent between observers. </p>\n<p>(It’s worth mentioning that all of this only works for observers like us “in situations like ours”. For example, at the <a href=\"https://www.wolframphysics.org/technical-introduction/potential-relation-to-physics/event-horizons-and-singularities-in-spacetime-and-quantum-mechanics/\" target=\"_blank\" rel=\"noopener\">“entanglement horizon” for a black hole</a>—where branchially-oriented edges in the multiway causal graph get “trapped”—time as we know it in some sense “disintegrates”, because an observer won’t be able to “knit together” the different branches of history to “form a consistent classical thought” about what happens.)</p>\n<h2 id=\"time-in-the-ruliad\">Time in the Ruliad</h2>\n<p>In what we’ve discussed so far we can think of the progress of time as being associated with the repeated application of rules that progressively “rewrite the state of the universe”. In the previous section we saw that these rules can be applied in many different ways, leading to many different underlying threads of history. </p>\n<p>But so far we’ve imagined that the rules that get applied are always the same—leaving us with the mystery of “Why those rules, and not others?” But this is where <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">the ruliad</a> comes in. Because the ruliad involves no such seemingly arbitrary choices: it’s what you get by following all possible computational rules.</p>\n<p>One can imagine many bases for the ruliad. One can make it from all possible hypergraph rewritings. Or all possible (multiway) Turing machines. But in the end it’s a single, unique thing: the entangled limit of all possible computational processes. There’s a sense in which “everything can happen somewhere” in the ruliad. But what gives the ruliad structure is that there’s a definite (essentially geometrical) way in which all those different things that can happen are arranged and connected.</p>\n<p>So what is our perception of the ruliad? Inevitably we’re part of the ruliad—so we’re observing it “from the inside”. But the crucial point is that what we perceive about it depends on what we are like as observers. And my big surprise in the past few years has been that assuming even just a little about what we’re like as observers immediately implies that what we perceive of the ruliad follows the core laws of physics we know. In other words, by assuming what we’re like as observers, we can in effect derive our laws of physics.</p>\n<p>The key to all this is the interplay between the computational irreducibility of underlying behavior in the ruliad, and our computational boundedness as observers (together with our related assumption of our persistence). And it’s this interplay that gives us the Second Law in statistical mechanics, the Einstein equations for the structure of spacetime, and (we think) the path integral in quantum mechanics. In effect what’s happening is that our computational boundedness as observers makes us equivalence things to the point where we are sampling only computationally reducible slices of the ruliad, whose characteristics can be described using recognizable laws of physics.</p>\n<p>So where does time fit into all of this? A central feature of the ruliad is that it’s unique—and everything about it is “abstractly necessary”. Much as given the definition of numbers, addition and equality it’s inevitable that one gets 1 + 1 = 2, so similarly given the definition of computation it’s inevitable that one gets the ruliad. Or, in other words, there’s no question about whether the ruliad exists; it’s just an abstract construct that inevitably follows from abstract definitions. </p>\n<p>And so at some level this means that the ruliad inevitably just “exists as a complete thing”. And so if one could “view it from outside” one could think of it as just a single timeless object, with no notion of time. </p>\n<p>But the crucial point is that we don’t get to “view it from the outside”. We’re embedded within it. And, what’s more, we must view it through the “lens” of our computational boundedness. And this is why we inevitably end up with a notion of time. </p>\n<p>We observe the ruliad from some point within it. If we were not computationally bounded then we could immediately compute what the whole ruliad is like. But in actuality we can only discover the ruliad “one computationally bounded step at a time”—in effect progressively applying bounded computations to “move through rulial space”. </p>\n<p>So even though in some abstract sense “the whole ruliad is already there” we only get to explore it step by step. And that’s what gives us our notion of time, through which we “progress”. </p>\n<p>Inevitably, there are many different paths that we could follow through the ruliad. And indeed every mind (and every observer like us)—with its distinct inner experience—presumably follows a different path. But much as we described for branchial space, the reason we have a shared notion of “objective reality” is presumably that we are all very close together in rulial space; we form in a sense a tight “rulial flock”.</p>\n<p>It’s worth pointing out that not every sampling of the ruliad that may be accessible to us conveniently corresponds to exploration of progressive slices of time. Yes, that kind of “progression in time” is characteristic of our physical experience, and our typical way of describing it. But what about our experience, say, of mathematics?</p>\n<p>The first point to make is that just as the ruliad contains all possible physics, it also <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/\">contains all possible mathematics</a>. If we construct the ruliad, say from hypergraphs, the nodes are now not “atoms of space”, but instead abstract elements (that in general <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#metamath-emes\">we call emes</a>) that form pieces of mathematical expressions and mathematical theorems. We can think of these abstract elements as being laid out now not in physical space, but in some abstract metamathematical space. </p>\n<p>In our physical experience, we tend to remain localized in physical space, branchial space, etc. But in “doing mathematics” it’s more as if we’re progressively expanding in metamathematical space, carving out some domain of “theorems we assume are true”. And while we could identify some kind of “path of expansion” to let us define some analog of time, it’s not a necessary feature of the way we explore the ruliad.</p>\n<p>Different places in the ruliad in a sense correspond to describing things using different rules. And by analogy to the concept of motion in physical space, we can effectively “move” from one place to another in the ruliad by translating the computations done by one set of rules to computations done by another. (And, yes, it’s nontrivial to even have the <a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/\">possibility of “pure motion”</a>.) But if we indeed remain localized in the ruliad (and can maintain what we can think of as our “coherent identity”) then it’s natural to think of there being a “path of motion” along which we progress “with time”. But when we’re just “expanding our horizons” to encompass more paradigms and to bring more of rulial space into what’s covered by our minds (so that in effect we’re “expanding in rulial space”), it’s not really the same story. We’re not thinking of ourselves as “doing computation in order to move”. Instead, we’re just identifying equivalences and using them to expand our definition of ourselves, which is something that we can at least approximate (much like in “quantum measurement” in traditional physics) as happening “outside of time”. Ultimately, though, everything that happens must be the result of computations that occur. It’s just that we don’t usually “package” these into what we can describe as a definite thread of time.</p>\n<h2 id=\"so-what-in-the-end-is-time\">So What in the End Is Time?</h2>\n<p>From the paradigm (and Physics Project ideas) that we’ve discussed here, the question “What is time?” is at some level simple: time is what progresses when one applies computational rules. But what’s critical is that time can in effect be defined abstractly, independent of the details of those rules, or the “substrate” to which they’re applied. And what makes this possible is the Principle of Computational Equivalence, and the ubiquitous phenomenon of computational irreducibility that it implies.</p>\n<p>To begin with, the fact that time can robustly be thought of as “progressing”, in effect in a linear chain, is a consequence of computational irreducibility—because computational irreducibility is what tells us that computationally bounded observers like us can’t in general ever “jump ahead”; we just have to follow a linear chain of steps. </p>\n<p>But there’s something else as well. The Principle of Computational Equivalence implies that there’s in a sense just one (ubiquitous) kind of computational irreducibility. So when we look at different systems following different irreducible computational rules, there’s inevitably a certain universality to what they do. In effect they’re all “accumulating computational effects” in the same way. Or in essence progressing through time in the same way.</p>\n<p>There’s a close analogy here with heat. It could be that there’d be detailed molecular motion that even on a large scale <a href=\"https://writings.stephenwolfram.com/2023/01/how-did-we-get-here-the-tangled-history-of-the-second-law-of-thermodynamics/#what-is-heat\">worked noticeably differently in different materials</a>. But the fact is that we end up being able to characterize any such motion just by saying that it represents a certain amount of heat, without getting into more details. And that’s very much the same kind of thing as being able to say that such-and-such an amount of time has passed, without having to get into the details of how some clock or other system that reflects the passage of time actually works.</p>\n<p>And in fact there’s more than a “conceptual analogy” here. Because the <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">phenomenon of heat is again a consequence of computational irreducibility</a>. And the fact that there’s a uniform, “abstract” characterization of it is a consequence of the universality of computational irreducibility.</p>\n<p>It’s worth emphasizing again, though, that just as with heat, a robust concept of time depends on us being computationally bounded observers. If we were not, then we’d able to break the Second Law by doing detailed computations of molecular processes, and we wouldn’t just describe things in terms of randomness and heat. And similarly, we’d be able to break the linear flow of time, either jumping ahead or following different threads of time. </p>\n<p>But as computationally bounded observers of computationally irreducible processes, it’s basically inevitable that—at least to a good approximation—we’ll view time as something that forms a single one-dimensional thread. </p>\n<p>In traditional mathematically based science there’s often a feeling that the goal should be to “predict the future”—or in effect to “outrun time”. But computational irreducibility tells us that in general we can’t do this, and that the only way to find out what will happen is just to run the same computation as the system itself, essentially step by step. But while this might seem like a letdown for the power of science, we can also see it as what gives meaning and significance to time. If we could always jump ahead then at some level nothing would ever fundamentally be achieved by the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-7--the-phenomenon-of-free-will\">passage of time (or, say, by the living of our lives)</a>; we’d always be able to just say what will happen, without “living through” how we got there. But computational irreducibility gives time and the process of it passing a kind of hard, tangible character.</p>\n<p>So what does all this imply for the various classic issues (and apparent paradoxes) that arise in the way time is usually discussed? </p>\n<p>Let’s start with the question of reversibility. The traditional laws of physics basically apply both forwards and backwards in time. And the ruliad is inevitably symmetrical between “forward” and “backward” rules. So why is it then that in our typical experience time always seems to “run in the same direction”? </p>\n<p>This is closely related to the Second Law, and once again it’s consequence of our computational boundedness interacting with underlying computational irreducibility. In a sense what defines the direction of time for us is that we (typically) find it much easier to remember the past than to predict the future. Of course, we don’t remember every detail of the past. We only remember what amounts to certain “filtered” features that “fit in our finite minds”. And when it comes to predicting the future, we’re limited by our inability to “outrun” computational irreducibility. </p>\n<p>Let’s recall how the Second Law works. It basically says that if we set up some state that’s “ordered” or “simple” then this will tend to “degrade” to one that’s “disordered” or “random”. (We can think of the evolution of the system as effectively “encrypting” the specification of our starting state to the point where we—as computationally bounded observers—can no longer recognize its ordered origins.) But because our underlying laws are reversible, this degradation (or “encryption”) must happen when we go both forwards and backwards in time:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/10/sw10082024timeAimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/10/sw10082024timeAimg3.png' alt='' title='' width='169' height='167'> </div>\n</p></div>\n<p>But the point is that our “experiential” definition of the direction of time (in which the “past” is what we remember, and the “future” is what we find hard to predict) is inevitably aligned with the “thermodynamic” direction of time we observe in the world at large. And the reason is that in both cases we’re defining the past to be something that’s computationally bounded (while the future can be computationally irreducible). In the experiential case the past is computationally bounded because that’s what we can remember. In the thermodynamic case it’s computationally bounded because those are the states we can prepare. In other words, the “arrows of time” are aligned because in both cases we are in effect “requiring the past to be simpler”. </p>\n<p>So what about time travel? It’s a concept that seems natural—and perhaps even inevitable—if one imagines that “time is just like space”. But it becomes a lot less natural when we think of time in the way we’re doing here: as a process of applying computational rules. </p>\n<p>Indeed, at the lowest level, these rules are by definition just sequentially applied, producing one state after another—and in effect “progressing in one direction through time”. But things get more complicated if we consider not just the raw, lowest-level rules, but what we might actually observe of their effects. For example, what if the rules lead to a state that’s identical to one they’ve produced before (as happens, for example, in a system with periodic behavior)? If we equivalence the state now and the state before (so we represent both as a single state) then we can <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#black-holes-singularities-etc\">end up with a loop in our causal graph (a “closed timelike curve”)</a>. And, yes, in terms of the raw sequence of applying rules these states can be considered different. But the point is that if they are identical in every feature then any observer will inevitably consider them the same. </p>\n<p>But will such equivalent states ever actually occur? As soon as there’s computational irreducibility it’s basically inevitable that the states will never perfectly match up. And indeed for the states to contain an observer like us (with “memory”, etc.) it’s basically impossible that they can match up. </p>\n<p>But can one imagine an observer (or a “timecraft”) that would lead to states that match up? Perhaps somehow it could carefully pick particular sequences of atoms of space (or elementary events) that would lead it to states that have “happened before”. And indeed in a computationally simple system this might be possible. But as soon as there’s computational irreducibility, this simply isn’t something one can expect any computationally bounded observer to be able to do. And, yes, this is directly analogous to why one <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/#maxwells-demon-and-the-character-of-observers\">can’t have a “Maxwell’s demon”</a> observer that “breaks the Second Law”. Or why one can’t have something that carefully navigates the lowest-level structure of space to <a href=\"https://writings.stephenwolfram.com/2020/10/faster-than-light-in-our-model-of-physics-some-preliminary-thoughts/\">effectively travel faster than light</a>. </p>\n<p>But even if there can’t be time travel in which “time for an observer goes backwards”, there can still be changes in “perceived time”, say as a result of relativistic effects associated with motion. For example, one classic relativistic effect is time dilation, in which “time goes slower” when objects go faster. And, yes, given certain assumptions, there’s a straightforward mathematical derivation of this effect. But in our effort to understand the nature of time we’re led to ask what its physical mechanism might be. And it turns out that in our Physics Project it has a surprisingly direct—and almost “mechanical”—explanation.</p>\n<p>One starts from the fact that in our Physics Project space and everything in it is represented by a hypergraph which is continually getting rewritten. And the evolution of any object through time is then defined by these rewritings. But if the object moves, then in effect it has to be “re-created at a different place in space”—and this process takes up a certain number of rewritings, leaving fewer for the intrinsic evolution of the object itself, and thus causing time to effectively “run slower” for it. (And, yes, while this is a qualitative description, one can make it quite formal and precise, and recover the usual formulas for relativistic time dilation.)</p>\n<p>Something similar happens with gravitational fields. In our Physics Project, energy-momentum (and thus gravity) is effectively associated with greater activity in the underlying hypergraph. And the presence of this greater activity leads to more rewritings, causing “time to run faster” for any object in that region of space (corresponding to the traditional “gravitational redshift”). </p>\n<p>More extreme versions of this occur in the context of black holes. (Indeed, one can roughly think of spacelike singularities as places where “time ran so fast that it ended”.) And in general—as we discussed above—there are many “relativistic effects” in which notions of space and time get mixed in various ways. </p>\n<p>But even at a much more mundane level there’s a certain crucial relationship between space and time for observers like us. The key point is that observers like us tend to “parse” the world into a sequence of “states of space” at successive “moments in time”. But the fact that we do this depends on some quite specific features of us, and in particular our effective physical scale in space as compared to time. </p>\n<p>In our everyday life we’re typically looking at scenes involving objects that are perhaps tens of meters away from us. And given the speed of light that means photons from these objects get to us in less than a microsecond. But it takes our brains milliseconds to register what we’ve seen. And this disparity of timescales is what leads us to view the world as consisting of a sequence of states of space at successive moments in time. </p>\n<p>If our brains “ran” a million times faster (i.e. at the speed of digital electronics) we’d perceive photons arriving from different parts of a scene at different times, and we’d presumably no longer view the world in terms of overall states of space existing at successive times. </p>\n<p>The same kind of thing would happen if we kept the speed of our brains the same, but dealt with scenes of a much larger scale (as we already do in dealing with spacecraft, astronomy, etc.).</p>\n<p>But while this affects what it is that we think time is “acting on”, it doesn’t ultimately affect the nature of time itself. Time remains that computational process by which successive states of the world are produced. Computational irreducibility gives time a certain rigid character, at least for computationally bounded observers like us. And the Principle of Computational Equivalence allows there to be a robust notion of time independent of the “substrate” that’s involved: whether us as observers, the everyday physical world, or, for that matter, the whole universe. </p>\n",

Addition. Subtraction. Maybe multiplication. Surely that’s not enough to be able to generate any serious complexity. In the early 1980s I had made the very surprising discovery that <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/\">very simple programs based on cellular automata could generate great complexity</a>. But how widespread was this phenomenon?</p>\n<p>At the beginning of the 1990s I had set about exploring this. Over and over I would consider <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs/\">some type of system</a> and be sure it was too simple to “do anything interesting”. And over and over again I would be wrong. And so it was that on the night of August 13, 1993, I thought I should check what could happen with integer functions defined using just addition and subtraction.<span id=\"more-62558\"></span></p>\n<p>I knew, of course, about <a href=\"https://www.wolframscience.com/nks/notes-3-5--fibonacci-numbers/\">defining functions by recursion</a>, like <tt><a href=\"http://reference.wolfram.com/language/ref/Fibonacci.html\">Fibonacci</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09232024surpriseAimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024surpriseimg1A.png' alt='' title='' width='330' height='17'> </div>\n</p></div>\n<p>But could I find something like this that would have complex behavior? I did the analog of what I have done so many times, and just started (symbolically) enumerating possible definitions.

But the behavior I’d seen reported for that function, while intricate, was <a href=\"https://www.wolframscience.com/nks/p130--recursive-sequences/\">nested and ultimately highly regular</a>. And, so far as I could tell, much like with <a href=\"https://www.wolframscience.com/nks/p27--how-do-simple-programs-behave/\">rule 30</a> and all the other systems I’d investigated, nobody had ever seen serious complexity in simple recursive functions.</p>\n<p>It was a nice example. But it was one among many. And when I published <em><a href=\"https://www.wolframscience.com/nks/\">A New Kind of Science</a></em> in 2002, I devoted just <a href=\"https://www.wolframscience.com/nks/chap-4--systems-based-on-numbers#sect-4-3--recursive-sequences\">four pages</a> (and <a href=\"https://www.wolframscience.com/nks/sect-4-3--recursive-sequences--notes/\">7 notes</a>) to “recursive sequences”—even though the <a href=\"https://www.wolframscience.com/nks/p130--recursive-sequences/\">gallery I made</a> of their behavior became a favorite page of mine:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09192024surpriseimg5.png' alt='Recursive sequences gallery' title='Recursive sequences gallery' width='383' height='422'/></p>\n<p>A year after the book was published we held our first <a href=\"https://education.wolfram.com/summer-school\">Wolfram Summer School</a>, and as an opening event I decided to <a href=\"https://writings.stephenwolfram.com/2007/07/science-live-and-in-public/\">do a live computer experiment</a>—in which I would try to make a real-time science discovery. The subject I chose was nestedly recursive functions. It took a few hours. But then, yes, we made a discovery! We found that there was a nestedly recursive function simpler than the ones I’d discussed in <em>A New Kind of Science</em> that already seemed to have very complex behavior: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09232024surpriseBimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024surpriseimg6A.png' alt='' title='' width='388' height='17'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02182025nestedlyc2cimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024surpriseimg7.png' alt='' title='' width='585' height='153'> </div>\n</p></div>\n<p>Over the couple of decades that followed I returned many times to nestedly recursive functions—particularly in explorations I did <a href=\"https://education.wolfram.com/summer-camp\">with high school</a> and other students, or in suggestions I made for student projects. Then recently I used them several times as <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/#combinators-in-the-wild-some-zoology\">“intuition-building examples” in various investigations</a>. </p>\n<p>I’d always felt my work with nestedly recursive functions was unfinished. Beginning about five years ago—particularly energized by our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a>—I started looking at harvesting seeds I’d sown in <em>A New Kind of Science</em> and before. I’ve <a href=\"https://writings.stephenwolfram.com/2024/08/five-most-productive-years-what-happened-and-whats-next/\">been on quite a roll</a>, with a few pages or even footnotes repeatedly flowering into rich book-length stories. And finally—particularly after my work last year on “<a href=\"https://writings.stephenwolfram.com/2023/09/expression-evaluation-and-fundamental-physics/\">Expression Evaluation and Fundamental Physics</a>”—I decided it was time to try to finish my exploration of nestedly recursive functions.</p>\n<p>Our modern <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> tools—as well as ideas from our Physics Project—provided some new directions to explore. But I still thought I pretty much knew what we’d find. And perhaps after all these years I should have known better. Because somehow in the computational universe—and in the world of <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#the-pure-basic-science-of-ruliology\">ruliology</a>—there are always surprises.</p>\n<p>And here, yet again, there was indeed quite a surprise.</p>\n<h2 id=\"the-basic-idea\">The Basic Idea</h2>\n<p>Consider the definition (later we’ll call this “P312”)</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09232024basicAimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024basicimg1A.png' alt='' title='' width='350' height='17'> </div>\n</p></div>\n<p>which we can also write as:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09232024basicAimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024basicimg2A.png' alt='' title='' width='300' height='17'> </div>\n</p></div>\n<p>The first few values for <em>f</em>[<em>n</em>] generated from this definition are:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09192024basicimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024basicimg3.png' alt='' title='' width='459' height='13'> </div>\n</p></div>\n<p>Continuing further we get:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02182025nestedlyc2cimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024basicimg4.png' alt='' title='' width='589' height='157'> </div>\n</p></div>\n<p>But how are these values actually computed?

For <em>n </em>= 2000 it so happens that we are at block 0 for the mod-1 subsequence. And the way things are set up, we just start by giving exactly the form of block 0 for each mod. So for mod 1 the block is: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09192024Acloserimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09192024Acloserimg10.png' alt='' title='' width='565' height='62'> </div>\n</p></div>\n<p>But now <em>n </em>= 2000 has offset 16 within this block, so the final value of <em>f</em>[2000] is simply the 16th value from this list, or 100. <em>f</em>[2001] is then simply the next element within this block, or 109. And so on—until we reach the end of the block. </p>\n<p>But what if we’re not dealing with block 0? For example, according to the table above, <em>f</em>[3000] is determined by mod-3 block 1.

As it turns out, though, the only values needed are <em>f</em>[–3], <em>f</em>[–2], <em>f</em>[–1] and <em>f</em>[0].</p>\n<p>How can one see this? In 3 + <em>f</em>[<em>n</em> – <em>f</em>[<em>n</em> – 2]] it’s only the outer <em>f</em> that can probe “far back” values.

Meanwhile, for larger <em>n</em>, there can never be additional “lookbacks”, because <em>f</em>[<em>n</em>] only grows like <img style=\"margin-bottom: 15px\" src='https://content.wolfram.com/sites/43/2024/09/sw09192024Acloserimg19.png' width= '35' height='20' align='absmiddle'>. </p>\n<p>So does any P312 recursion always have the same lookback? So far, we’ve considered specifically the initial condition <em>f</em>[<em>n</em>] = 1 for all <em>n</em> ≤ 0. But what if we change the value of <em>f</em>[0]?

The tree graph is basically an “unrolled” version of the minimal graph, in which all the possible paths that can be taken from the root node to the initial condition nodes have been treed out. </p>\n<p>In general, the number of edges that come out of a single node in a evaluation graph will be equal to the number of instances of the function <em>f</em> that appear on the right-hand side of the recursive definition we’re using (i.e. 2 in the case of the standard Fibonacci definition). So this means that if the maximum length of path from the root to the initial conditions is <em>s</em>, the maximum number of nodes that can appear in the “unrolled” graph is 2<sup><em>s</em></sup>. And whenever there are a fixed set of initial conditions (i.e. if there’s always the same lookback), the maximum path length is essentially <em>n</em>—implying in the end that the maximum possible number of nodes in the unrolled graph will be 2<sup><em>n</em></sup>.</p>\n<p>(In the actual case of the Fibonacci recurrence, the number of nodes in the unrolled graph is, or about 1.6<sup><em>n</em></sup>.)</p>\n<p>But if we actually evaluate <em>f</em>[7]—say in the Wolfram Language—what is the sequence of <em>f</em>[<em>n</em>]’s that we’ll end up computing? Or, in effect, how will the evaluation graph be traversed? Here are the results for the unrolled and minimal evaluation graphs—i.e. without and with caching:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09262024updatesfinalBimg22_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09262024updatesfinalBimg22.png' alt='' title='' width='621' height='84'> </div>\n</p></div>\n<p>Particularly in the first case this isn’t the only conceivable result we could have gotten. It’s the way it is here because of the particular “<a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/#the-question-of-evaluation-order\">leftmost innermost</a>” evaluation order that the Wolfram Language uses by default. In effect, we’re traversing the graph in a depth-first way. In principle we could use other traversal orders, leading to <em>f</em>[<em>n</em>]’s being evaluated in different orders. But unless we allow other operations (like <em>f</em>[3] + <em>f</em>[3] <img style=\"margin-bottom: -1px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow2.png\" width='15' height='11' > 2 <em>f</em>[3]) to be interspersed with <em>f</em> evaluations, we’ll still always end up with the same number of <em>f</em> evaluations for a given evaluation graph.</p>\n<p>But which is the “correct” evaluation graph? The unrolled one? Or the minimal one? Well, it depends on the computational primitives we’re prepared to use. With a pure stack machine, the unrolled graph is the only one possible.

And for nearly a hundred years there’s been a distinction made between “<a href=\"https://www.wolframscience.com/nks/notes-4-3--primitive-recursive-functions/\">primitive recursive functions</a>” and “general recursive functions”.

But it always just finds value 1—which is easy for us to represent without, for example, any extra nesting, etc.</p>\n<p>The ultimate (historical) definition of primitive recursion, though, doesn’t involve subsets of the Wolfram Language (the definition was given almost exactly 100 years too early!). Instead, it involves a <a href=\"https://www.wolframscience.com/nks/notes-4-3--primitive-recursive-functions/\">specific set of simple primitives</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09252024finalupdatesimg14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09252024finalupdatesimg14.png' alt='' title='' width='669' height='174'> </div>\n</p></div>\n<p>(An alternative, equivalent definition for recursion—explicitly involving <tt><a href=\"http://reference.wolfram.com/language/ref/Fold.html\">Fold</a></tt>—is <nobr><tt>r[g_, h_] := Fold[{u, v} <img style=\"margin-bottom: -2px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow.png\" width='18' height='12' > h[u, v, ##2]], g[##2]</nobr>, </tt><tt><a href=\"http://reference.wolfram.com/language/ref/Range.html\">Range</a></tt><tt>[0, #1 – 1]] &</tt>.)</p>\n<p>So can our nestedly recursive functions be written purely in terms of these primitives? The answer is yes, though it’s seriously complicated. A simple function like <tt><a href=\"http://reference.wolfram.com/language/ref/Plus.html\">Plus</a></tt> can for example be written as <tt>r</tt><tt>[p[1], s]</tt>, so that e.g. <tt>r[p[1], s][2,3]<img style=\"margin-bottom: -1px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow2.png\" width='15' height='11' >5</tt>. <tt><a href=\"http://reference.wolfram.com/language/ref/Times.html\">Times</a></tt> can be written as <tt>r[z, c</tt>[<tt>Plus</tt>, <tt>p[1], p[3]]]</tt> or <tt>r[z, c[r[p[1], s], p[1], p[3]]]</tt>, while <tt><a href=\"http://reference.wolfram.com/language/ref/Factorial.html\">Factorial</a></tt> can be written as <tt>r[c[s, z], c[</tt><tt>Times</tt>, <tt>p[1], c[s, p[2</tt><tt>]]]]</tt>. But even <tt><a href=\"http://reference.wolfram.com/language/ref/Fibonacci.html\">Fibonacci</a></tt>, for example, seems to require a very much longer specification.</p>\n<p>In writing “primitive-recursive-style” definitions in Wolfram Language we accumulated values in lists and associations. But in the ultimate definition of primitive recursion, there are no such constructs; the only form of “data” is positive integers. But for our definitions of nestedly recursive functions we can use a “<a href=\"https://arxiv.org/pdf/1706.04129\" target=\"_blank\" rel=\"noopener\">tupling function</a>” that “packages up” any list of integer values into a single integer (and an untupling function that unpacks it).

Well, <tt>If</tt> can be written in primitive recursive form too: for example, <tt>r[c[s, z], c[f, c[s, p[2]]]][n]</tt> is equivalent to <tt>If</tt><tt>[n ≤ 0, 1, f[n]]</tt>.</p>\n<p>So our nestedly recursive functions as we’re using them are indeed primitive recursive. Or, more strictly, finding values <em>f</em>[<em>n</em>] is primitive recursive. Asking questions like “For what <em>n</em> does <em>f</em>[<em>n</em>] reach 1000?” might not be primitive recursive. (The obvious way of answering them involves a <tt><a href=\"http://reference.wolfram.com/language/ref/FoldWhile.html\">FoldWhile</a></tt>-style non-primitive-recursive search, but proving that there’s no primitive recursive way to answer the question is likely very much harder.)</p>\n<p>By the way, it’s worth commenting that while for primitive recursive functions it’s always possible to compute a value <em>f</em>[<em>n</em>] for any <em>n</em>, that’s not necessarily true for general recursive functions. For example, if we ask “For what <em>n</em> does <em>f</em>[<em>n</em>] reach 1000?” there might simply be no answer to this; <em>f</em>[<em>n</em>] might never reach 1000. And when we look at the computations going on underneath, the key distinction is that in evaluating primitive recursive functions, the computations always halt, while for general recursive functions, they may not.</p>\n<p>So, OK. Our nestedly recursive functions can be represented in “official primitive recursive form”, but they’re very complicated in that form. So that raises the question: what functions can be represented simply in this form?

When we have functions (like T212) that “reach back” progressively further as <em>n</em> increases, there’s a question of what they’ll find. We’ve simply assumed <em>f</em>[<em>n</em>] = 1 for <em>n</em> ≤0. But what if there was something more complicated there? Even if <em>f</em>[–<em>m</em>] was given by some primitive recursive function, say <em>p</em>[<em>m</em>], it seems possible that in computing <em>f</em>[<em>n</em>] one could end up somehow “bouncing back and forth” between positive and negative arguments, and in effect searching for an <em>m</em> for which <em>p</em>[<em>m</em>] has some particular value, and in doing that searching one could find oneself outside the domain of primitive recursive functions.</p>\n<p>And this raises yet another question: are all definitions we can give of nestedly recursive functions consistent? Consider for example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09252024primitiveimg34_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09252024primitiveimg35.png' alt='' title='' width='319' height='14'> </div>\n</p></div>\n<p>Now ask: what is <em>f</em>[1]? We apply the recursive definition. But it gives us <nobr><em>f</em>[1] = 1 – <em>f</em>[<em>f</em>[0]]</nobr> or <em>f</em>[1] = 1 – <em>f</em>[1], or, in other words, an inconsistency. There are many such inconsistencies that seem to “happen instantly” when we apply definitions. But it seems conceivable that there could be “insidious inconsistencies” that show up only after many applications of a recursive definition. And it’s also conceivable that one could end up with “loops” like <em>f</em>[<em>i</em>] = <em>f</em>[<em>i</em>]. And things like this could be reasons that <em>f</em>[<em>n</em>] might not be a “total function”, defined for all <em>n</em>.</p>\n<p>We’ve seen all sorts of complex behavior in nestedly recursive functions. And what the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> suggests is that whenever one sees complex behavior, one must in some sense be dealing with computations that are “as sophisticated as any computation can be”. And in particular one must be dealing with computations that can somehow support <a href=\"https://www.wolframscience.com/nks/p642--the-phenomenon-of-universality/\">computation universality</a>. </p>\n<p>So what would it mean for a nestedly recursive function to be universal? For a start, one would need some way to “program” the function. There seem to be a couple of possibilities. First, one could imagine packing both “code” and “data” into the argument <em>n</em> of <em>f</em>[<em>n</em>]. So, for example, one might use some form of tupling function to take a description of a rule and an initial state for a Turing machine, together with a specification of a step number, then package all these things into an integer <em>n</em> that one feeds into one’s universal nestedly recursive function <em>f</em>. Then the idea would be that the value computed for <em>f</em>[<em>n</em>] could be decoded to give the state of the Turing machine at the specified step. (Such a computation by definition always halts—but much as one computes with Turing machines by successively asking for the next steps in their evolution, one can imagine setting up a “harness” that just keeps asking for values of <em>f</em>[<em>n</em>] at an infinite progression of values <em>n</em>.)</p>\n<p>Another possible approach to making a universal nestedly recursive function is to imagine feeding in a “program” through the initial conditions one gives for the function. There might well need to be decoding involved, but in some sense what one might hope is that just by changing its initial conditions one could get a nestedly recursive function with a specific recursive definition to emulate a nestedly recursive function with any other recursive definition (or, say, for a start, any <a href=\"https://reference.wolfram.com/language/ref/LinearRecurrence.html\">linear recurrence</a>).</p>\n<p>Perhaps one could construct a complicated nestedly recursive function that would have this property. But what the Principle of Computational Equivalence suggests is that it should be possible to find the property even in “naturally occurring cases”—like P312 or T212. </p>\n<p>The situation is probably going to be quite analogous to what happened with the <a href=\"https://www.wolframscience.com/nks/chap-11--the-notion-of-computation#sect-11-8--the-rule-110-cellular-automaton\">rule 110 cellular automaton</a> or the <a href=\"https://www.wolframscience.com/prizes/tm23/\"><em>s</em> = 2, <em>k</em> = 3 596440 Turing machine</a>. By looking at the actual typical behavior of the system one got some intuition about what was likely to be going on. And then later, with great effort, it became possible to actually prove computation universality. </p>\n<p>In the case of nestedly recursive functions, we’ve seen here examples of just how diverse the behavior generated by changing initial conditions can be. It’s not clear how to harness this diversity to extract some form of universality. But it seems likely that the “raw material” is there. And that nestedly recursive functions will show themselves as able join so many other systems in fitting into the framework defined by the Principle of Computational Equivalence.</p>\n<h2 id=\"some-history\">Some History</h2>\n<p>Once one has the concept of functions and the concept of recursion, nestedly recursive functions aren’t in some sense a “complicated idea”. And between this fact and the fact that nestedly recursive functions haven’t historically had a clear place in any major line of mathematical or other development it’s quite difficult to be sure one’s accurately tracing their history. But I’ll describe here at least what I currently know.</p>\n<p>The concept of something like recursion is very old. It’s closely related to mathematical induction, which was already being used for proofs by Euclid around 300 BC. And in a quite different vein, around the same time (though not recorded in written form until many centuries later) <a href=\"https://www.wolframscience.com/nks/notes-3-5--fibonacci-numbers/\">Fibonacci numbers</a> arose in Indian culture in connection with the <a href=\"https://www.wolframscience.com/nks/notes-2-3--the-concept-of-rules/\">enumeration of prosody</a> (“How many different orders are there in which to say the Sanskrit words in this veda?”). </p>\n<p>Then in 1202 Leonardo Fibonacci, at the end of his calculational math book <em>Liber Abaci</em> (which was notable for popularizing Hindu-Arabic numerals in the West) stated—more or less as a recreational example—his “rabbit problem” in recursive form, and explicitly listed the Fibonacci numbers up to 377. But despite this early appearance, explicit recursively defined sequences remained largely a curiosity until as late as the latter part of the twentieth century.</p>\n<p>The concept of an abstract function began to emerge with calculus in the late 1600s, and became more solidified in the 1700s—but basically always in the context of continuous arguments. A variety of specific examples of recurrence relations—for binomial coefficients, <a href=\"https://writings.stephenwolfram.com/2015/12/untangling-the-tale-of-ada-lovelace/#the-bernoulli-number-computation\">Bernoulli numbers</a>, etc.—were in fairly widespread use. But there didn’t seem to have yet been a sense that there was a general mathematical structure to study. </p>\n<p>In the course of the 1800s there had been an <a href=\"https://www.wolframscience.com/nks/notes-12-9--history-of-concept-of-mathematics/\">increasing emphasis on rigor and abstraction</a> in mathematics, leading by the latter part of the century to a serious effort to axiomatize concepts associated with numbers. Starting with concepts like the recursive definition of integers by repeated application of the successor operation, by the time of <a href=\"https://www.wolframscience.com/nks/notes-12-9--axioms-for-arithmetic/\">Peano’s axioms for arithmetic</a> in 1891 there was a clear general notion (particularly related to the induction axiom) that (integer) functions could be defined recursively. And when <a href=\"https://writings.stephenwolfram.com/2020/12/where-did-combinators-come-from-hunting-the-story-of-moses-schonfinkel/#gottingen-center-of-the-mathematical-universe\">David Hilbert</a>’s program of axiomatizing mathematics got underway at the beginning of the 1900s, it was generally assumed that all (integer) functions of interest could actually be defined specifically using primitive recursion.</p>\n<p>The notation for recursively specifying functions gradually got cleaner, making it easier to explore more elaborate examples. And in 1927 Wilhelm Ackermann (a student of Hilbert’s) introduced (in completely modern notation) a “<a href=\"https://www.wolframscience.com/nksonline/page-906c/\">reasonable mathematical function</a>” that—as we discussed above—he showed was not primitive recursive. And right there, in his paper, without any particular comment, is a nestedly recursive function definition:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg1.png' alt='Ackermann nestedly recursive function paper' title='Ackermann nestedly recursive function paper' width='533' height='113'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg2.png' alt='Ackermann nestedly recursive function definition' title='Ackermann nestedly recursive function definition' width='533' height='139'/></p>\n<p>In 1931 Kurt Gödel further streamlined the representation of recursion, and solidified the notion of general recursion. There soon developed a whole field of recursion theory—though most of it was concerned with general issues, not with specific, concrete recursive functions. A notable exception was the work of Rózsa Péter (Politzer), beginning in the 1930s, and leading in 1957 to her book <em>Recursive Functions—</em>which contains a chapter on “Nested Recursion” (here in English translation):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg3.png' alt='Nested recursion book chapter' title='Nested recursion book chapter' width='468' height='261'/></p>\n<p>But despite the many specific (mostly primitive) recursive functions discussed in the rest of the book, this chapter doesn’t stray far from the particular function Ackermann defined (or at least Péter’s variant of it). </p>\n<p>What about the recreational mathematics literature? By the late 1800s there were all sorts of publications involving numbers, games, etc. that at least implicitly involved recursion (an example being Édouard Lucas’s 1883 <a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-multicomputational-systems/#towers-of-hanoi-etc\">Tower of Hanoi puzzle</a>). But—perhaps because problems tended to be stated in words rather than mathematical notation—it doesn’t seem as if nestedly recursive functions ever showed up. </p>\n<p>In the theoretical mathematics literature, a handful of somewhat abstract papers about “nested recursion” did appear, an example being one in 1961 by William Tait, then at Stanford: </p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg4.png' alt='Nested recursion paper by William Tait' title='Nested recursion paper by William Tait' width='504' height='165'/></p>\n<p>But, meanwhile, the general idea of recursion was slowly beginning to go from purely theoretical to more practical. <a href=\"https://writings.stephenwolfram.com/2023/08/remembering-the-improbable-life-of-ed-fredkin-1934-2023-and-his-world-of-ideas-and-stories/#computers\">John McCarthy</a>—who had coined the term “artificial intelligence”—was designing LISP as “the language for AI” and by 1960 was writing papers with titles like “<a href=\"https://writings.stephenwolfram.com/2020/12/combinators-and-the-story-of-computation/#practical-computation\">Recursive Functions of Symbolic Expressions and Their Computation by Machine</a>”. </p>\n<p>In 1962 McCarthy came to Stanford to found the AI Lab there, bringing with him enthusiasm for both AI and recursive functions. And by 1968 these two topics had come together in an effort to use “AI methods” to prove properties of programs, and in particular programs involving recursive functions. And in doing this, John McCarthy came up with an example he intended to be awkward—that’s exactly a nestedly recursive function:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg5.png' alt='John McCarthy nestedly recursive function example' title='John McCarthy nestedly recursive function example' width='623' height='185'/></p>\n<p>In our notation, it would be:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg6.png' alt='' title='' width='251' height='30'> </div>\n</p></div>\n<p>And it became known as “McCarthy’s 91-function” because, yes, for many <em>n</em>, <em>f</em>[<em>n</em>] = 91. These days it’s trivial to evaluate this function—and to find out that <em>f</em>[<em>n</em>] = 91 only up to <em>n</em> = 102:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02182025nestedlyc2cimg64_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg7.png' alt='' title='' width='271' height='77'> </div>\n</p></div>\n<p>But even the evaluation graph is somewhat large</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg8.png' alt='' title='' width='473' height='371'> </div>\n</p></div>\n<p>and in pure recursive evaluation the recursion stack can get deep—which back then was a struggle for LISP systems to handle. </p>\n<p>There were efforts at theoretical analysis, for example by Zohar Manna, who in 1974 published <em>Mathematical Theory of Computation</em> which—in a section entitled “Fixpoints of Functionals”—presents the 91-function and other nestedly recursively functions, particularly in the context of <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/#the-question-of-evaluation-order\">evaluation-order questions</a>. </p>\n<p>In the years that followed, a variety of nestedly recursive functions were considered in connection with proving theorems about programs, and with practical assessments of LISP systems, a notable example being Ikuo Takeuchi’s 1978 triple recursive function:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg9.png' alt='Ikuo Takeuchi triple recursive function example' title='Ikuo Takeuchi triple recursive function example' width='623' height='261'/></p>\n<p>But in all these cases the focus was on how these functions would be evaluated, not on what their behavior would be (and it was typically very simple). </p>\n<p>But now we have to follow another thread in the story. Back in 1961, right on the Stanford campus, a then-16-year-old Douglas Hofstadter was being led towards nestedly recursive functions. As Doug tells it, it all started with him seeing that squares are interspersed with gaps of 1 or 2 between triangular numbers, and then noticing patterns in those gaps (and later realizing that they <a href=\"https://www.wolframscience.com/nks/notes-4-2--relation-of-powers-to-substitution-systems/\">showed nesting</a>). Meanwhile, at Stanford he had access to a computer running Algol, a language which (like LISP and unlike Fortran) supported recursion (though this wasn’t particularly advertised, since recursion was still generally considered quite obscure). </p>\n<p>And as Doug tells it, within a year or two he was using Algol to do things like recursively create trees representing English sentences. Meanwhile—in a kind of imitation of the Eleusis “guess-a-card-rule” game—Doug was apparently challenging his fellow students to a “function game” based on guessing a math function from specified values. And, as he tells it, he found that functions that were defined recursively were the ones people found it hardest to guess.</p>\n<p>That was all in the early 1960s, but it wasn’t until the mid-1970s that Doug Hofstadter returned to such pursuits. After various adventures, Doug was back at Stanford—writing what became his book <em>Gödel, Escher, Bach</em>. And in 1977 he sent a letter to Neil Sloane, creator of the 1973 <em>A Handbook of Integer Sequences</em> (and what’s now the <a href=\"https://oeis.org/\" target=\"_blank\" rel=\"noopener\">Online Encyclopedia of Integer Sequences, or OEIS</a>):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg10.png' alt='Douglas Hofstadter letter to Neil Sloane' title='Douglas Hofstadter letter to Neil Sloane' width='623' height='354'/></p>\n<p>As suggested by the accumulation of “sequence ID” annotations on the letter, Doug’s “eta sequences” had <a href=\"https://www.wolframscience.com/nks/notes-4-2--relation-of-powers-to-substitution-systems/\">actually been studied in number theory before</a>—in fact, since at least the 1920s (they are now usually called <a href=\"https://mathworld.wolfram.com/BeattySequence.html\">Beatty sequences</a>). But the letter went on, now introducing some related sequences—that had nestedly recursive definitions: </p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg11.png' alt='Sequences with nestedly recursive definitions' title='Sequences with nestedly recursive definitions' width='623' height='388'/></p>\n<p>As Doug pointed out, these particular sequences (which were derived from golden ratio versions of his “eta sequences”) have a very regular form—which we would now call nested. And it was the properties of this form that Doug seemed most concerned about in his letter. But actually, as we saw above, just a small change in initial conditions in what I’m calling S1 would have led to much wilder behavior. But that apparently wasn’t something Doug happened to notice. A bit later in the letter, though, there was another nestedly recursive sequence—that Doug described as a “horse of an entirely nother color”: the “absolutely CRAZY” Q sequence:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg12.png' alt='Crazy Q sequence' title='Crazy Q sequence' width='623' height='211'/></p>\n<p>Two years later, Doug’s <em>Gödel, Escher, Bach</em> book was published—and in it, tucked away at the bottom of page 137, a few pages after a discussion of recursive generation of text (with examples such as “the strange bagels that the purple cow without horns gobbled”), there was the Q sequence: </p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg13.png' alt='Chaotic Q sequence' title='Chaotic Q sequence' width='623' height='195'/></p>\n<p>Strangely, though, there was no picture of it, and Doug listed only 17 terms (which, until I was writing this, was all I assumed he had computed):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg14.png' alt='17 Q-sequence terms' title='17 Q-sequence terms' width='623' height='455'/></p>\n<p>So now nestedly recursive sequences were out in the open—in what quickly became a very popular book. But I don’t think many people noticed them there (though, as I’ll discuss, I did). <em>Gödel, Escher, Bach</em> is primarily a playful book focused on exposition—and not the kind of place you’d expect to find a new, mathematical-style result. </p>\n<p>Still—quite independent of the book—Neil Sloane showed Doug’s 1977 letter to his Bell Labs colleague Ron Graham, who within a year made a small mention of the Q sequence in a staid academic math publication (in a characteristic “state-it-as-a-problem” Erdös form):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg15.png' alt='Erdös and Graham math paper' title='Erdös and Graham math paper' width='533' height='174'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg16.png' alt='Erdös and Graham math paper continued' title='Erdös and Graham math paper continued' width='533' height='181'/></p>\n<p>There was a small and tight-knit circle of serious mathematicians—essentially all of whom, as it happens, I personally knew—who would chase these kinds of easy-to-state-but-hard-to-solve problems. Another was Richard Guy, who soon included the sequence as part of problem E31 in his <em>Unsolved Problems in Number Theory</em>, and mentioned it again a few years later.<em> </em></p>\n<p>But for most of the 1980s little was heard about the sequence. As it later turns out, a senior British applied mathematician named Brian Conolly (who wasn’t part of the aforementioned tight-knit circle) had—presumably as a kind of hobby project—made some progress, and in 1986 had written to Guy about it. Guy apparently misplaced the letter, but later told Conolly that John Conway and Sol Golomb had worked on similar things.</p>\n<p>Conway presumably got the idea from Hofstadter’s work (though he had a habit of obfuscating his sources). But in any case, on July 15, 1988, Conway gave a talk at Bell Labs entitled “Some Crazy Sequences” (note the word “crazy”, just like in Hofstadter’s letter to Sloane) in which he discussed the <a href=\"https://oeis.org/A004001\" target=\"_blank\" rel=\"noopener\">regular-enough-to-be-mathematically-interesting sequence</a> (which we’re calling G<sub>3</sub>111 here):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg18_copy.txt' data-c2c-type='text/html'><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg19.png' alt='' title='' width='404' height='14'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02182025nestedlyc2cimg65_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg20.png' alt='' title='' width='358' height='98'> </div>\n</p></div>\n<p>Despite its visual regularity, Conway couldn’t mathematically prove certain features of the wiggles in the sequence—and in his talk offered a $10,000 prize for anyone who could. By August a Bell Labs mathematician named Colin Mallows had done it. Conway claimed (later to be contradicted by video evidence) that he’d only offered $1000—and somehow the whole affair landed as a story in the August 30 <em>New York Times</em> under the heading “<a href=\"https://www.nytimes.com/1988/08/30/science/intellectual-duel-brash-challenge-swift-response.html\" target=\"_blank\" rel=\"noopener\">Intellectual Duel: Brash Challenge, Swift Response</a>”. But in any case, this particular nestedly recursive sequence became known as “Conway’s Challenge Sequence”. </p>\n<p>So what about <a href=\"https://writings.stephenwolfram.com/2016/05/solomon-golomb-19322016/\">Sol Golomb</a>? It turns out he’d started writing a paper—though never finished it:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg21.png' alt='Discrete Chaos paper' title='Discrete Chaos paper' width='533' height='249'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg22.png' alt='Discrete Chaos paper continued' title='Discrete Chaos paper continued' width='533' height='254'/></p>\n<p>He’d computed 280 terms of the Q sequence (he wasn’t much of a computer user) and noticed a few coincidences. But he also mentioned another kind of nestedly recursive sequence, no doubt inspired by his work on feedback shift registers:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg23_copy.txt' data-c2c-type='text/html'><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg24.png' alt='' title='' width='178' height='14'> </div>\n</p></div>\n<p>As he noted, the behavior depends greatly on the initial conditions, though is always eventually periodic—with his student Unjeng Cheng having found long-period examples.</p>\n<p>OK, so by 1988 nestedly recursive functions had at least some notoriety. So what happened next? Not so much. There’s a <a href=\"https://content.wolfram.com/sites/43/2024/09/NestedlyRecursiveFunctions-Bibliography-9-27.pdf\">modest academic literature</a> that’s emerged over the last few decades, mostly concentrated very specifically around “Conway’s Challenge Sequence”, Hofstadter’s Q function, or very similar “meta Fibonacci” generalizations of them. And so far as I know, even the first published large-scale picture of the Q sequence only appeared in 1998 (though I had pictures of it many years earlier):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg25.png' alt='Klaus Pinn Q-sequence paper' title='Klaus Pinn Q-sequence paper' width='533' height='287'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024historyimg26.png' alt='Klaus Pinn Q-sequence paper continued' title='Klaus Pinn Q-sequence paper continued' width='533' height='365'/></p>\n<p>Why wasn’t more done with nestedly recursive functions? At some level it’s because they tend to have too much computational irreducibility—making it pretty difficult to say much about them in traditional mathematical ways. But perhaps more important, studying them broadly is really a matter of <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#the-pure-basic-science-of-ruliology\">ruliology</a>: it requires the idea of exploring spaces of rules, and of expecting the kinds of behavior and phenomena that are characteristic of systems in the computational universe. And that’s something that’s still not nearly as widely understood as it should be.</p>\n<h2 id=\"my-personal-story-with-nestedly-recursive-functions\">My Personal Story with Nestedly Recursive Functions</h2>\n<p>I think 1979 was the year when I first took recursion seriously. I’d heard about the Fibonacci sequence (though not under that name) as a young child a decade earlier. I’d implicitly (and sometimes explicitly) encountered recursion (sometimes through error messages!) in computer algebra systems I’d used. In science, I’d studied fractals quite extensively (<a href=\"https://www.stephenwolfram.com/publications/the-father-of-fractals/?ref=josephnoelwalker.com\">Benoit Mandelbrot</a>’s book having appeared in 1977), and I’d been exposed to things like iterated maps. And I’d quite extensively studied cascade processes, <a href=\"https://content.wolfram.com/sw-publications/2020/07/qcd-model-annihilation.pdf\">notably of quarks and gluons in QCD</a>.</p>\n<p>As I think about it now, I realize that for several years I’d written programs that made use of recursion (and I had quite a lot of exposure to LISP, and the culture around it). But it was in 1979—<a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">having just started using C</a>—that I first remember writing a program (for doing percolation theory) where I explicitly thought “this is using recursion”. But then, in late 1979, I began to design <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">SMP (“Symbolic Manipulation Program”)</a>, the forerunner of the modern Wolfram Language. And in doing this I quickly solidified my knowledge of mathematical logic and the (then-fledgling) field of theoretical computer science.</p>\n<p>My concept of repeated transformations for symbolic expressions—which is still the core of Wolfram Language today—is somehow fundamentally recursive. And by the time we had the first signs of life for our SMP system, Fibonacci was one of our very first tests. We soon tried the Ackermann function too. And in 1980 I became very interested in the problem of evaluation order, particularly for recursive functions—and the best treatment I found of it (though at the time not very useful to me) was in none other than the book by Zohar Manna that I mentioned above. (In a strange twist, I was at that time also studying gauge choices in physics—and it was <a href=\"https://writings.stephenwolfram.com/2023/09/expression-evaluation-and-fundamental-physics/\">only last year that I realized</a> that they’re fundamentally the same thing as evaluation orders.) </p>\n<p>It was soon after it came out in 1979 that I first saw Douglas Hofstadter’s book. At the time I wasn’t too interested in its Lewis-Carroll-like aspects, or its exposition; I just wanted to know what the “science meat” in it was. And somehow I found the page about the Q sequence, and filed it away as “something interesting”. </p>\n<p>I’m not sure when I first implemented the Q sequence in SMP, but by the time we released Version 1.0 in July 1981, there it was: an external package (hence the “X” prefix) <a href=\"https://files.wolframcdn.com/pub/www.stephenwolfram.com/pdf/smp-library.pdf\" target=\"_blank\">for evaluating “Hofstadter’s recursive function”</a>, elegantly using memoization—with the description I gave saying (presumably because that’s what I’d noticed) that its values “have several properties of randomness”:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg1.png' alt='Hofstadter recursive function' title='Hofstadter recursive function' width='583' height='315'/></p>\n<p>Firing up a copy of SMP today—running on a virtual machine that still thinks it’s 1986—I can run this code, and easily compute the function:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09252024personalAimg2A.png' alt='SMP evaluation' title='SMP evaluation' width='581' height='345'/></p>\n<p>I can even plot it—though without an emulator for a 1980s-period storage-tube display, only the ASCIIfied rendering works:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09252024personalAimg3A-v3.png' alt='ASCIIfied rendering' title='ASCIIfied rendering' width='581' height='314'/></p>\n<p>So what did I make of the function back in 1981? I was interested in <a href=\"https://www.wolframscience.com/nks/chap-1--the-foundations-for-a-new-kind-of-science/#sect-1-4--the-personal-story-of-the-science-in-this-book\">how complexity and randomness could occur in nature</a>. But at the time, I didn’t have enough of a framework to understand the connection. And, as it was, I was just starting to explore cellular automata, which seemed a lot more “nature like”—and which soon led me to things like <a href=\"https://writings.stephenwolfram.com/2019/10/announcing-the-rule-30-prizes\">rule 30</a> and the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">phenomenon of computational irreducibility</a>. </p>\n<p>Still, I didn’t forget the Q sequence. And when I was building Mathematica I again used it as a test (the .tq file extension came from the brief period in 1987 when we were trying out “Technique” as the name of the system):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg4.png' alt='Combinatorial functions' title='Combinatorial functions' width='583' height='123'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg5.png' alt='Combinatorial functions continued' title='Combinatorial functions continued' width='583' height='200'/></p>\n<p>When Mathematica 1.0 was released on June 23, 1988, the Q sequence appeared again, this time as an example in the soon-in-every-major-bookstore Mathematica book:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg6.png' alt='Q sequence in Mathematica book' title='Q sequence in Mathematica book' width='623' height='81'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg7.png' alt='Q sequence in Mathematica book continued' title='Q sequence in Mathematica book continued' width='623' height='254'/></p>\n<p>I don’t think I was aware of Conway’s lecture that occurred just 18 days later. And for a couple of years I was consumed with tending to a young product and a young company. But by 1991, I was getting ready to launch into basic science again. Meanwhile, the number theorist (and today horologist) Ilan Vardi—yet again from Stanford—had been working at Wolfram Research and writing a book entitled <em>Computational Recreations in Mathematica</em>, which included a long section on the analysis of Takeuchi’s nested recursive function (“TAK”). My email archive records an exchange I had with him:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg8.png' alt='Wolfram–Vardi email' title='Wolfram–Vardi email' width='483' height='603'/></p>\n<p>He suggested a “more symmetrical” nested recursive function. I responded, including a picture that made it fairly clear that this particular function would have only nested behavior, and not seem “random”:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg9.png' alt='Wolfram–Vardi followup email' title='Wolfram–Vardi follow-up email' width='483' height='392'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg10.png' alt='Nested recursive function graphic' title='Nested recursive function graphic' width='263' height='218'/></p>\n<p>By the summer of 1991 I was in the thick of exploring different kinds of systems with simple rules, discovering the remarkable complexity they could produce, and filling out what became <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs/\">Chapter 3 of <em>A New Kind of Science</em>: “The World of Simple Programs”</a>. But then came <a href=\"https://www.wolframscience.com/nks/chap-4--systems-based-on-numbers/\">Chapter 4: “Systems Based on Numbers”</a>. I had known since the mid-1980s about the <a href=\"https://www.wolframscience.com/nks/p120--elementary-arithmetic/\">randomness in things like digit sequences</a> produced by successive arithmetic operations. But what about randomness in pure sequences of integers? I resolved to find out just what it would take to produce randomness there. And so it was that on August 13, 1993, I came to be enumerating possible symbolic forms for recursive functions—and selecting ones that could generate at least 10 terms:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg11.png' alt='Symbolic forms for recursive functions' title='Symbolic forms for recursive functions' width='423' height='203'/></p>\n<p>As soon as I plotted the “survivors” I could see that interesting things were going to happen:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg12.png' alt='Recursive function graphs' title='Recursive function graphs' width='612' height='492'/></p>\n<p>Was this complexity somehow going to end? I checked out to 10 million terms. And soon I started <a href=\"https://www.wolframscience.com/nks/p129--recursive-sequences/\">collecting my “prize specimens” and making a gallery of them</a>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg13.png' alt='Recursive functions gallery' title='Recursive functions gallery' width='533' height='434'/></p>\n<p>I had some one-term recurrences, and some two-term ones. Somewhat shortsightedly I was always using “Fibonacci-like” initial conditions <em>f</em>[1] = <em>f</em>[2] = 1—and I rejected any recurrence that tried to “look back” to <em>f</em>[0], <em>f</em>[–1], etc. And at the time, with this constraint, I only found “really interesting” behavior in two-term recurrences. </p>\n<p>In 1994 I returned briefly to recursive sequences, <a href=\"https://www.wolframscience.com/nks/notes-4-3--properties-of-recursive-sequences/\">adding a note</a> “solving” a few of them, and discussing the evaluation graphs of others:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg14.png' alt='Properties of sequences' title='Properties of sequences' width='483' height='284'/></p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg15.png' alt='Evaluation graphs' title='Evaluation graphs' width='483' height='360'/></p>\n<p>When I finally finished <em>A New Kind of Science</em> in 2002, I included a <a href=\"https://www.wolframscience.com/nks/notes-2-3--close-approaches-to-core-discoveries/\">list of historical “Close approaches”</a> to its core discoveries, one of them being Douglas Hofstadter’s work on recursive sequences:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg16-v2.png' alt='Douglas Hofstadter work on recursive sequences' title='Douglas Hofstadter work on recursive sequences' width='620' height='511'/></p>\n<p>In retrospect, back in 1981 I should have been able to take the “Q sequence” and recognize in it the essential “rule 30 phenomenon”. But as it was, it took another decade—and many other explorations in the computational universe—for me to build up the right conceptual framework to see this. In <em>A New Kind of Science</em> I studied many kinds of systems, probing them far enough, I hoped, to see their most important features. But recursive functions were an example where I always felt there was more to do; I felt I’d only just scratched the surface.</p>\n<p>In June 2003—a year <a href=\"https://writings.stephenwolfram.com/2022/05/the-making-of-a-new-kind-of-science/#how-to-publish-a-book\">after <em>A New Kind of Science</em> was published</a>—we held our first <a href=\"https://education.wolfram.com/summer-school\">summer school</a>. And as a way to introduce methodology—and be sure that people knew I was fallible and approachable—I decided on the first day of the summer school to do a “<a href=\"https://writings.stephenwolfram.com/2007/07/science-live-and-in-public/\">live experiment</a>”, and try to stumble my way to discovering something new, live and in public. </p>\n<p>A few minutes before the session started, I picked the subject: recursive functions. I began with some examples I knew. Then it was time to go exploring. At first lots of functions “didn’t work” because they were looking back too far. But then someone piped up “Why not just say that <em>f</em>[<em>n</em>] is 1 whenever <em>n</em> isn’t a positive integer?” Good idea! And very easy to try. </p>\n<p>Soon we had the “obvious” functions written (today <tt><a href=\"http://reference.wolfram.com/language/ref/Apply.html\">Apply</a></tt><tt>[</tt><tt><a href=\"http://reference.wolfram.com/language/ref/Plus.html\">Plus</a></tt><tt>, ...]</tt> could be just <tt><a href=\"http://reference.wolfram.com/language/ref/Total.html\">Total</a></tt><tt>[...]</tt>, but otherwise there’s nothing “out of date” here):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09252024personalboxc2cimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09252024personalboxc2cimg1.png' alt='' title='' width='595' height='164'> </div>\n</p></div>\n<p>In a typical story of Wolfram-Language-helps-one-think-clearly, the obvious function was also very general, and allowed a recurrence with any number of terms. So why not start with just one term? And immediately, there it was—what we’re now calling T311:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg19.png' alt='T311' title='T311' width='593' height='304'/></p>\n<p>And then a plot (yes, after Version 6 one didn’t need the <tt><a href=\"http://reference.wolfram.com/language/ref/Show.html\">Show</a></tt> or the trailing “;”):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg20.png' alt='RSValues plot' title='RSValues plot' width='589' height='400'/></p>\n<p>Of course, as is the nature of computational constructions, this is something timeless—that looks the same today as it did 21 years ago (well, except that now our plots display with color by default).</p>\n<p>I thought this was a pretty neat discovery. And I just couldn’t believe that years earlier I’d failed to see the obvious generalization of having “infinite” initial conditions. </p>\n<p>The next week I did a followup session, this time talking about how one would write up a discovery like this. We started off with possible titles (including audience suggestions):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg21-v2.png' alt='Suggested titles' title='Suggested titles' width='610' height='320'/></p>\n<p>And, yes, the first title listed is exactly the one I’ve now used here. In the notebook I created back then, there were first some notes (some of which should still be explored!):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg22.png' alt='Title notes' title='Title notes' width='353' height='474'/></p>\n<p>Three hours later (on the afternoon of July 11, 2003) there’s another notebook, with the beginnings of a writeup:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg23.png' alt='Initial recursive functions writeup' title='Initial recursive functions writeup' width='632' height='423'/></p>\n<p>By the way, another thing we came up with at the summer school was the (non-nestedly) recursive function: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg24_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg25.png' alt='' title='' width='352' height='14'> </div>\n</p></div>\n<p>Plotting <em>g</em>[<em>n</em> + 1] – <em>g</em>[<em>n</em>] gives:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2025/02/sw02182025nestedlyc2cimg66_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg26.png' alt='' title='' width='482' height='129'> </div>\n</p></div>\n<p>And, yes, bizarrely (and reminiscent of McCarthy’s 91-function) for <em>n</em> ≥ 396, <em>g</em>[<em>n</em> + 1] – <em>g</em>[<em>n</em>] is always 97, and <em>g</em>[<em>n</em>] = 38606 + 97 (<em>n</em> – 396).</p>\n<p>But in any case, a week or so after my “writeups” session, the summer school was over. In January 2004 I briefly picked the project up again, and made some pictures that, yes, show interesting structure that perhaps I should investigate now:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg27.png' alt='f[n - f[n - 1]]' title='f[n - f[n - 1]]' width='453' height='619'/></p>\n<p>In the years that followed, I would occasionally bring nestedly recursive functions out again—particularly in interacting with high school and other students. And at our summer programs I suggested projects with them for a number of students.</p>\n<p>In 2008, they seemed like an “obvious interesting thing” to add to our <a href=\"https://demonstrations.wolfram.com/\">Demonstrations Project</a>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/09/sw09242024personalimg28.png' alt='NKS summer school live experiment' title='NKS summer school live experiment' width='623' height='305'/></p>\n<p>But mostly, they languished. Until, that is, my <a href=\"https://writings.stephenwolfram.com/2024/08/five-most-productive-years-what-happened-and-whats-next/\">burst of “finish this” intellectual energy</a> that followed the <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/\">launch of our Physics Project in 2020</a>. So here now, finally, after a journey of 43 years, I feel like I’ve been able to do some justice to nestedly recursive functions, and provided a bit more illumination to yet another corner of the computational universe. </p>\n<p>(Needless to say, there are many, many additional questions and issues to explore. Different primitives, e.g. <tt><a href=\"http://reference.wolfram.com/language/ref/Mod.html\">Mod</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/Floor.html\">Floor</a></tt>, etc. Multiple functions that refer to each other. Multiway cases. Functions based on rational numbers. And endless potential approaches to analysis, identifying pockets of regularity and computational reducibility.)</p>\n<h2 id=\"thanks\" style='font-size:1.2rem'>Thanks</h2>\n<p style='font-size:90%'>Thanks to Brad Klee for extensive help. Thanks also to those who’ve worked on nestedly recursive functions as students at our summer programs over the years, including Roberto Martinez (2003), Eric Rowland (2003), Chris Song (2021) and Thomas Adler (2024).

So… what happened? Well, what happened was great. And in fact I’ve just had the most productive five years of my life.

Oh, and a bunch of big—and beautiful—ideas and results.</p>\n<p>It’s been wonderful. And unexpected. I’ve spent my life alternating between technology and basic science, progressively building a taller and taller tower of practical capabilities and intellectual concepts (and sharing what I’ve done with the world). Five years ago everything was going well, and making steady progress. But then there were the questions I never got to. Over the years I’d come up with a certain number of big questions. And some of them, within a few years, I’d answered. But others I never managed to get around to. </p>\n<p>And five years ago, as I explained in my birthday livestream, I began to think “it’s now or never”. I had no idea how hard the questions were. Yes, I’d spent a lifetime building up tools and knowledge. But would they be enough? Or were the questions just not for our time, but only perhaps for some future century?<span id=\"more-62482\"></span></p>\n<p>At several points before in my life I’d faced such issues—and things had worked out well (<em><a href=\"https://www.wolframscience.com/nks/\">A New Kind of Science</a></em>, <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>, etc.). And from this, I had gotten a certain confidence about what might be possible. In addition, as a serious <a href=\"https://writings.stephenwolfram.com/category/historical-perspectives\">student of intellectual history</a>, I had a sense of what kind of boldness was needed. Five years ago there wasn’t really anything that made me need to do something big and new. But I thought: “What the heck. I might as well try. I’ll never know what’s possible unless I try.”</p>\n<p>A major theme of my work since the early 1980s had been <a href=\"https://www.wolframscience.com/nksonline/toc.html\">exploring the consequences of simple computational rules</a>. And I had found the surprising result that even extremely simple rules could lead to immensely complex behavior. So what about the universe? Could it be that at a fundamental level <a href=\"https://www.wolframscience.com/nks/chap-9--fundamental-physics/\">our whole universe is just following some simple computational rule</a>? </p>\n<p>I had begun my career in the 1970s as a teenager <a href=\"https://www.stephenwolfram.com/publications/academic/\">studying the frontiers of existing physics</a>. And at <a href=\"https://writings.stephenwolfram.com/2020/04/how-we-got-here-the-backstory-of-the-wolfram-physics-project/#maybe-it-could-apply-to-physics\">first I couldn’t see</a> how computational rules could connect to what is known in physics. But in the early 1990s I had an idea, and by the late 1990s I had developed it and gotten some very suggestive results. But when I published these in <em>A New Kind of Science</em> in 2002, even my friends in the physics community <a href=\"https://writings.stephenwolfram.com/2020/04/how-we-got-here-the-backstory-of-the-wolfram-physics-project/#please-dont-do-that-project\">didn’t seem to care</a>—and I decided to concentrate my efforts elsewhere (e.g. building Wolfram|Alpha, <a href=\"https://reference.wolfram.com/language/\">Wolfram Language</a>, etc.).</p>\n<p>But I didn’t stop thinking “one day I need to get back to my physics project”. And in 2019 I decided: “What the heck. Let’s try it now.” It helped that I’d made a piece of technical progress the year before, and that <a href=\"https://writings.stephenwolfram.com/2020/04/how-we-got-here-the-backstory-of-the-wolfram-physics-project/#two-young-physicists-and-a-little-idea\">now two young physicists</a> were enthusiastic to work with me on the project. </p>\n<p>And so it was, soon after <a href=\"https://x.com/stephen_wolfram/status/1167118524537610240\" target=\"_blank\" rel=\"noopener\">my birthday in 2019</a>, that we embarked on our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a>. It was a mixture of computer experiments and big concepts. But before the end of 2019 it was clear: <a href=\"https://writings.stephenwolfram.com/2020/04/how-we-got-here-the-backstory-of-the-wolfram-physics-project/#oh-my-gosh-its-actually-going-to-work\">it was going to work</a>! It was an amazing experience. Thing after thing in physics that had always been mysterious I suddenly understood. And it was beautiful—a theory of such strength built on a structure of such incredible simplicity and elegance. </p>\n<p><a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/\">We announced</a> what we’d figured out in April 2020, right when the pandemic was in full swing. There was still much to do (and there still is today). But the overall picture was clear. I later learned that a century earlier many well-known physicists were beginning to think in a similar direction (matter is discrete, light is discrete; space must be too) but back then they hadn’t had the computational paradigm or the other tools needed to move this forward. And now the responsibility had fallen on us to do this. (Pleasantly enough, given our framework, many modern areas of mathematical physics seemed to fit right in.)</p>\n<p>And, yes, figuring out the basic “machine code” for our universe was of course pretty exciting. But seeing an old idea of mine blossom like this had another very big effect on me. It made me think: “OK, what about all those other projects I’ve been meaning to do? Maybe it’s time to do those too.”</p>\n<p>And something else had happened as well. In doing the Physics Project we’d developed a new way of thinking about things—not just computational, <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\">but “multicomputational”</a>. And actually, the <a href=\"https://www.wolframscience.com/nks/chap-5--two-dimensions-and-beyond#sect-5-6--multiway-systems\">core ideas behind this</a> were in <em>A New Kind of Science</em> too. But somehow I’d never taken them seriously enough before, and never extended my intuition to encompass them. But now with the Physics Project I was doing this. And I could see that the ideas could also go much further. </p>\n<p>So, yes, I had a new and powerful conceptual framework for doing science. And I had all the technology of the modern <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>. But in 2020 I had another thing too—in effect, a new distribution channel for my ideas and efforts. Early in my career I had used <a href=\"https://www.stephenwolfram.com/publications/academic/\">academic papers</a> as my “channel” (at one point in 1979 even averaging a paper every few weeks). But in the late 1980s I had a very different kind of channel: embodying my ideas in the design and implementation of <a href=\"https://www.wolfram.com/mathematica/\">Mathematica</a> and what’s now the Wolfram Language. Then in the 1990s I had another channel: putting everything together into what became my book <em>A New Kind of Science</em>. </p>\n<p>After that was published in 2002 I would occasionally write small posts—for the <a href=\"https://community.wolfram.com/content?curTag=wolfram%20science\">community site</a> around the science in my book, for our <a href=\"https://blog.wolfram.com/\">corporate blog</a>, etc. And in 2010 I <a href=\"https://writings.stephenwolfram.com/2010/09/welcome-to-the-blog/\">started my own blog</a>. At first I mostly just wrote small, fun pieces. But by 2015—partly driven by telling historical stories (<a href=\"https://writings.stephenwolfram.com/2015/11/george-boole-a-200-year-view/\">200th anniversary of George Boole</a>, <a href=\"https://writings.stephenwolfram.com/2015/12/untangling-the-tale-of-ada-lovelace/\">200th anniversary of Ada Lovelace</a>, …)—the things I was writing were getting ever meatier. (There’d actually already been some <a href=\"https://writings.stephenwolfram.com/2012/03/the-personal-analytics-of-my-life/\">meaty ones</a> about <a href=\"https://writings.stephenwolfram.com/category/personal-analytics/\">personal analytics</a> in 2012.)</p>\n<p>And by 2020 my pattern was set and I would routinely write 50+ -page pieces, full of pictures (all with immediately runnable “<a href=\"https://reference.wolfram.com/language/ref/ClickToCopy.html\">click-to-copy</a>” code) and intended for anyone who cared to read them. Finally I had a good channel again. And I started using it. As I’d found over the years—whether with <a href=\"https://reference.wolfram.com/language/\">language documentation</a> or with <em>A New Kind of Science</em>—the very act of exposition was a critical part of organizing and developing my ideas. </p>\n<p>And now I started producing pieces. Some were directly about specific topics around the Physics Project. But within two months I was already writing about a “spinoff”: “<a href=\"https://www.wolframphysics.org/bulletins/2020/06/exploring-rulial-space-the-case-of-turing-machines/\" target=\"_blank\" rel=\"noopener\">Exploring Rulial Space: The Case of Turing Machines</a>”. I had realized that one of the places the ideas of the Physics Project should apply was to the foundations of mathematics, and to metamathematics. In a footnote to <em>A New Kind of Science</em> I had introduced the idea of “<a href=\"https://www.wolframscience.com/nks/notes-12-9--empirical-metamathematics/\">empirical metamathematics</a>”. And in the summer of 2020, fuelled by my newfound “finish those old projects” mindset, I ended up writing an 80-page piece on “<a href=\"https://writings.stephenwolfram.com/2020/09/the-empirical-metamathematics-of-euclid-and-beyond/\">The Empirical Metamathematics of Euclid and Beyond</a>”. </p>\n<p>December 7, 1920 was the date a certain <a href=\"https://writings.stephenwolfram.com/2021/03/a-little-closer-to-finding-what-became-of-moses-schonfinkel-inventor-of-combinators/\">Moses Schönfinkel introduced</a> what we <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-and-the-story-of-computation/\">now call combinators</a>: the very first clear foundations for universal computation. I had always found combinators interesting (if hard to understand). I had used ideas from them back around 1980 in <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">the predecessor of what’s now the Wolfram Language</a>. And I had <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs#sect-3-10--symbolic-systems\">talked about them a bit</a> in <em>A New Kind of Science</em>. But as the centenary approached, I decided to make a <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/\">more definitive study</a>, in particular using methods from the Physics Project. And, for good measure, even in the middle of the pandemic I tracked down the <a href=\"https://writings.stephenwolfram.com/2021/03/a-little-closer-to-finding-what-became-of-moses-schonfinkel-inventor-of-combinators/\">mysterious history of Moses Schönfinkel</a>.</p>\n<p>In March 2021, there was <a href=\"https://www.youtube.com/watch?v=ultMxODJE7o\" target=\"_blank\" rel=\"noopener\">another centenary</a>, this time of <a href=\"https://writings.stephenwolfram.com/2021/03/after-100-years-can-we-finally-crack-posts-problem-of-tag-a-story-of-computational-irreducibility-and-more/#more-about-the-history\">Emil Post’s tag system</a>, and again I decided to finish <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs#sect-3-7--tag-systems\">what I’d started</a> in <em>A New Kind of Science</em>, and write <a href=\"https://writings.stephenwolfram.com/2021/03/after-100-years-can-we-finally-crack-posts-problem-of-tag-a-story-of-computational-irreducibility-and-more/\">a definitive piece</a>, this time running to about 75 pages.</p>\n<p>One might have thought that the excursions into <a href=\"https://writings.stephenwolfram.com/2020/09/the-empirical-metamathematics-of-euclid-and-beyond/\">empirical metamathematics</a>, <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/\">combinators</a>, <a href=\"https://writings.stephenwolfram.com/2021/03/after-100-years-can-we-finally-crack-posts-problem-of-tag-a-story-of-computational-irreducibility-and-more/\">tag systems</a>, <a href=\"https://www.wolframphysics.org/bulletins/2020/06/exploring-rulial-space-the-case-of-turing-machines/\" target=\"_blank\" rel=\"noopener\">rulial</a> and <a href=\"https://www.wolframphysics.org/bulletins/2021/02/multiway-turing-machines/\" target=\"_blank\" rel=\"noopener\">multiway Turing machines</a> would be distractions. But they were not. Instead, they just deepened my understanding and intuition for the new ideas and methods that had come out of the Physics Project. As well as finishing projects that I’d wondered about for decades (and the world had had open for a century). </p>\n<p>Perhaps not surprisingly given its fundamental nature, the Physics Project also engaged with some deep <a href=\"https://writings.stephenwolfram.com/category/philosophy/\">philosophical issues</a>. People would ask me about them with some regularity. And in March 2021 I started writing a bit about them, beginning with <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/\">a piece on consciousness</a>. The next month I wrote “<a href=\"https://writings.stephenwolfram.com/2021/04/why-does-the-universe-exist-some-perspectives-from-our-physics-project/\">Why Does the Universe Exist? Some Perspectives from Our Physics Project</a>”. (This piece of writing happened to coincide with the few days in my life when I’ve needed to do active cryptocurrency trading—so I was in the amusing position of thinking about a philosophical question about as deep as they come, interspersed with making cryptocurrency trades.)</p>\n<p>Everything kept weaving together. These philosophical questions made me internalize just how important the nature of the observer is in our Physics Project. Meanwhile I started thinking about the relationship of methods from the Physics Project to distributed computing, and to economics. And in May 2021 that intersected with practical <a href=\"https://www.youtube.com/watch?v=h94VrSuPFJc\" target=\"_blank\" rel=\"noopener\">blockchain questions</a>, which caused me to write about “<a href=\"https://writings.stephenwolfram.com/2021/05/the-problem-of-distributed-consensus/\">The Problem of Distributed Consensus</a>”—which would soon show up again in the <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">science and philosophy of observers</a>. </p>\n<p>The fall of 2021 involved really leaning into the new <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\">multicomputational paradigm</a>, among other things giving a <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/#potential-application-areas\">long list of where it might apply</a>: metamathematics, chemistry, molecular biology, evolutionary biology, neuroscience, immunology, linguistics, economics, machine learning, distributed computing. And, yes, in a sense this was my “to do” list. In many ways, half the battle was just defining this. And I’m happy to say that just three years later, we’ve already made a big dent in it. </p>\n<p>While all of this was going on, I was also energetically pursuing my “day job” as CEO of Wolfram Research. <a href=\"https://writings.stephenwolfram.com/2020/03/in-less-than-a-year-so-much-new-launching-version-12-1-of-wolfram-language-mathematica/\">Version 12.1</a> of the Wolfram Language had come out less than a month before the Physics Project was announced. <a href=\"https://writings.stephenwolfram.com/2020/12/launching-version-12-2-of-wolfram-language-mathematica-228-new-functions-and-much-more/\">Version 12.2</a> right after the combinator centenary. And in 2021 there were two new versions. In all 635 new functions, all of which <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\" target=\"_blank\" rel=\"noopener\">I had carefully reviewed</a>, and many of which I’d been deeply involved in designing. </p>\n<p>It’s a pattern in the history of science (as well as technology): some new methodology or some new paradigm is introduced. And suddenly vast new areas are opened up. And there’s lots of juicy “low-hanging fruit” to be picked. Well, that’s what had happened with the ideas from our Physics Project, and the concept of multicomputation. There were many directions to go, and many people wanting to get involved. And in 2021 it was becoming clear that something organizational had to be done: this wasn’t a job for a company (even for one as terrific and innovative as ours is), it was <a href=\"https://writings.stephenwolfram.com/2022/04/weve-got-a-science-opportunity-overload-its-time-to-launch-the-wolfram-institute/\">a job for something like an institute</a>. (And, yes, in 2022, we indeed launched what’s now the <a href=\"https://www.wolframinstitute.org/\" target=\"_blank\" rel=\"noopener\">Wolfram Institute for Computational Foundations of Science</a>.)</p>\n<p>But back in 1986, I had started the <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#theres-a-whole-new-field-to-build\">very first institute concentrating on complexity</a> and how it could arise from simple rules. Running it hadn’t been a good fit for me back then, and <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">very quickly I started our company</a>. In 2002, when <a href=\"https://writings.stephenwolfram.com/2022/05/the-making-of-a-new-kind-of-science/\"><em>A New Kind of Science</em> was published</a>, I’d thought again about starting an institute. But it didn’t happen. But now there really seemed to be no choice. I started reflecting on what had happened to “complexity”, and whether there was something to leverage from the institutional structure that had grown up around it. Nearly 20 years after the publication of <em>A New Kind of Science</em>, what should “complexity” be now?</p>\n<p>I wrote “<a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/\">Charting a Course for ‘Complexity’: Metamodeling, Ruliology and More</a>”—and in doing so, finally invented a word for the “pure basic science of what simple rules do”: <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#the-pure-basic-science-of-ruliology\">ruliology</a>. </p>\n<p>My original framing of what became our Physics Project had been to try to “find a computational rule that gives our universe”. But I’d always found this unsatisfying. Because even if we had the rule, we’d still be left asking “why this one, and not another?” But in 2020 there’d been a dawning awareness of a possible answer.</p>\n<p>Our Physics Project is based on the idea of <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#how-it-works\">applying rules to abstract hypergraphs</a> that represent space and everything in it. But given a particular rule, there are in general many ways it can be applied. And a key idea in our Physics Project is that somehow it’s always <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/\" target=\"_blank\" rel=\"noopener\">applied in all these ways</a>—leading to many separate threads of history, that branch and merge—and, importantly, giving us a way to <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#the-inevitability-of-quantum-mechanics\">understand quantum mechanics</a>.</p>\n<p>We talked about these different threads of history corresponding to different places in <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/the-concept-of-branchial-graphs/\" target=\"_blank\" rel=\"noopener\">branchial space</a>—and about how the laws of quantum mechanics are <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#general-relativity-and-quantum-mechanics-are-the-same-idea\">the direct analogs in branchial space</a> (or branchtime) of the laws of classical mechanics (and gravity) in physical space (or spacetime). But what if instead of just applying a given rule in all possible ways, we applied all possible rules in all possible ways?</p>\n<p>What would one get? In November 2021 I came up with a name for it: <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">the ruliad</a>. A year and a half earlier I’d already been <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#why-this-universe-the-relativity-of-rules\">starting to talk about rulial space</a>—and the idea of us as observers perceiving the universe in terms of our particular sampling of rulial space. But naming the ruliad really helped to crystallize the concept. And I began to realize that I had come upon a breathtakingly broad intellectual arc. </p>\n<p>The ruliad is the biggest computational thing there can be: it’s the entangled limit of all possible computations. It’s abstract and it’s unique—and it’s as inevitable in its structure as 2 + 2 = 4. It encompasses everything computational—including us. So what then is physics? Well, it’s a description of how <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#experiencing-the-ruliad\">observers like us embedded in the ruliad</a> perceive the ruliad.</p>\n<p><a href=\"https://writings.stephenwolfram.com/2023/02/a-50-year-quest-my-personal-journey-with-the-second-law-of-thermodynamics/#computational-irreducibility-and-rule-30\">Back in 1984 I’d introduced</a> what<a href=\"https://www.wolframscience.com/nks/notes-12-6--history-of-computational-irreducibility/\"> I saw as being the very central concept</a> of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>: the idea that there are many computational processes whose outcomes can be found only by following them step by step—with no possibility of doing what mathematical science was used to, and being able to “jump ahead” and make predictions without going through each step. At the beginning of the 1990s, when I began to work on <em>A New Kind of Science</em>, I’d invented the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a>—the idea that systems whose behavior isn’t obviously simple will always tend to be equivalent in the sophistication of the computations they do. </p>\n<p>Given the Principle of Computational Equivalence, computational irreducibility was inevitable. It followed from the fact that the observer could only be as computationally sophisticated as the system they were observing, and so would never be able to “jump ahead” and shortcut the computation. There’d come to be a belief that eventually science would always let one predict (and control) things. But here—from inside science—was a fundamental limitation on the power of science. All these things I’d known in some form since the 1980s, and with clarity since the 1990s. </p>\n<p>But the ruliad took things to another level. For now I could see that the very laws of physics we know were determined by the way we are as observers. I’d always imagined that the laws of physics just are the way they are. But now I realized that we could potentially derive them from the inevitable structure of the ruliad, and very basic features of what we’re like as observers. </p>\n<p>I hadn’t seen this philosophical twist coming. But somehow it immediately made sense. We weren’t getting our laws of physics from nothing; we were getting them from being the way we are. Two things seemed to be critical: that as observers we are computationally bounded, and that (somewhat relatedly) we believe we are persistent in time (i.e. we have a continuing thread of experience through time). </p>\n<p>But even as I was homing in on the idea of the ruliad as it applied to physics, I was also thinking about another application: the <a href=\"https://www.wolframscience.com/metamathematics/\">foundations of mathematics</a>. I’d been interested in the foundations of mathematics for a very long time; in fact, in the design of Mathematica (and what’s now the Wolfram Language) and <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">its predecessor SMP</a>, I’d made central use of ideas that I’d developed from thinking about the foundations of mathematics. And in <em>A New Kind of Science</em>, I’d included <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-9--implications-for-mathematics-and-its-foundations\">a long section on the foundations of mathematics</a>, discussing things like the network of all possible theorems, and the space of all possible axiom systems.</p>\n<p>But now I was developing a clearer picture. The ruliad represented not only all possible physics, but also all possible mathematics. And the actual mathematics that we perceive—like the actual physics—would be determined by our nature as observers, in this case mathematical observers. There were lots of technical details, and it wasn’t until March 2022 that I published “<a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/\">The Physicalization of Metamathematics and Its Implications for the Foundations of Mathematics</a>”. </p>\n<p>In some ways this finished what I’d started in the mid-1990s. But it went much further than I expected, in particular in providing a sweeping unification of the foundations of physics and mathematics. It talked about what the ultimate limit of mathematics would be like. And it talked about how “human-level mathematics”—where we can discuss things like the Pythagorean theorem rather than just the microdetails of underlying axioms—emerges for observers like us just like our human-level impression of physical space emerges from the underlying network of atoms of space. </p>\n<p>One of the things I’d discovered in computational systems is how common computational irreducibility is, along with undecidability. And I had always wondered why undecidability wasn’t more common in typical mathematics. But now I had an answer: it just isn’t what mathematical observers like us “see” in the ruliad. At some level, this was a very philosophical result. But for me it also had <a href=\"https://www.wolframscience.com/metamathematics/implications-for-the-future-of-mathematics/\">practical implications</a>, notably greatly validating the idea of using higher-level computational language to represent useful human-level mathematics, rather than trying to drill down to “axiomatic machine code”. </p>\n<p>October 22, 2021 had marked <a href=\"https://writings.stephenwolfram.com/2021/10/celebrating-a-third-of-a-century-of-mathematica-and-looking-forward/\">a third of a century of Mathematica</a>. And May 14, 2022 was the <a href=\"https://writings.stephenwolfram.com/2022/05/twenty-years-later-the-surprising-greater-implications-of-a-new-kind-of-science/\">20th anniversary of <em>A New Kind of Science</a></em>. And in contextualizing my activities, and planning for the future, I’ve increasingly found it useful to reflect on what I’ve done before, and how it’s worked out. And in both these cases I could see that seeds I’d planted many years earlier had blossomed, sometimes in ways I’d suspected they might, and sometimes in ways that far exceeded what I’d imagined. </p>\n<p>What had I done right? The key, it seemed, was drilling down to find the essence of things, and then developing that. Even if I hadn’t been able to imagine quite what could be built on them, I’d been able to construct solid foundations, that successfully encapsulated things in the cleanest and simplest ways. </p>\n<p>In talking about observers and the ruliad—and in fact our Physics Project in general—I kept on making analogies to the way that the gas laws and fluid dynamics emerge from the complicated underlying dynamics of molecules. And at the core of this is the <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">Second Law of thermodynamics</a>. </p>\n<p>Well, as it happens, the very first foundational question in physics that I ever seriously studied was the origin of the Second Law. But that was <a href=\"https://writings.stephenwolfram.com/2023/02/a-50-year-quest-my-personal-journey-with-the-second-law-of-thermodynamics/\">when I was 12 years old</a>, in 1972. For more than a century the Second Law <a href=\"https://writings.stephenwolfram.com/2023/01/how-did-we-get-here-the-tangled-history-of-the-second-law-of-thermodynamics/\">had been quite mysterious</a>. But when I discovered computational irreducibility in 1984 I soon realized that it <a href=\"https://writings.stephenwolfram.com/2023/02/a-50-year-quest-my-personal-journey-with-the-second-law-of-thermodynamics/#computational-irreducibility-and-rule-30\">might be the key to the Second Law</a>. And in the summer of 2022—armed with a new perspective on the importance of observers—I decided I’d better once and for all write down how the Second Law works.</p>\n<p>Once again, there were lots of <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">technical details</a>. And as a way to check my ideas I decided to go back and try to untangle the rather confused <a href=\"https://writings.stephenwolfram.com/2023/01/how-did-we-get-here-the-tangled-history-of-the-second-law-of-thermodynamics/\">150-year history of the Second Law</a>. It was an interesting exercise, satisfying for seeing how my new ways of thinking clarified things, but cautionary in seeing how wrong turns had been taken—and solidified—in the past. But in the end, there it was: the Second Law was a consequence of the interplay between underlying computational irreducibility, and our limitations as observers.</p>\n<p>It had taken half a century, but finally I had finished the project I’d started when I was 12 years old. I was on a roll finishing things. But I was also realizing that a bigger structure than I’d ever imagined was emerging. The Second Law project completed what I think is the most beautiful thing I’ve ever discovered. That all three of the core theories of twentieth century physics—general relativity, quantum mechanics and the Second Law (statistical mechanics)—have the same origin: the interplay between the underlying computational structure of the ruliad, and our characteristics and limitations as observers. </p>\n<p>And I knew it didn’t stop there. I’d already applied the same kind of thinking to the foundations of mathematics. And I was ready to start applying it to all sorts of deep questions in science, in philosophy, and beyond. But at the end of 2022, just as I was finishing my pieces about the Second Law, there was a surprise: <a href=\"https://openai.com/index/chatgpt/\" target=\"_blank\" rel=\"noopener\">ChatGPT</a>.</p>\n<p>I’d been <a href=\"https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/#personal-backstory\">following AI and neural nets</a> for decades. I first simulated a neural net in 1981. <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">My first company, started in 1981</a>, had, to my chagrin, been labeled an “AI company”. And from the early 2010s we’d integrated neural nets into the Wolfram Language. But—like the creators of ChatGPT—I didn’t expect the capabilities that emerged in ChatGPT. And as soon as I saw ChatGPT I started trying to understand it. What was it really doing? What would its capabilities be?</p>\n<p>In the world at large, there was a sense of shock: if AI can do this now, soon it’ll be able to do everything. But I immediately thought about computational irreducibility. And it gave us limitations. But those limitations would inevitably apply to AIs as well. There would be things that couldn’t be “quickly figured out by pure thought”—by humans and AIs alike. And, by the way, I’d just spent four decades building a way to represent things computationally, and actually do systematic computations on them—because that was the point of the Wolfram Language. </p>\n<p>So immediately I could see <a href=\"https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/\">we were in a very interesting position</a>. The Wolfram Language had the completely unique mission of creating a full-scale computational language. And now this was a crucial tool for AIs. The AIs could provide a very interesting and useful broad linguistic interface. But when it came to solid computation, they were—like humans—going to need a tool. Conveniently, Wolfram|Alpha already communicated in natural language. And it took only a few weeks to hook up Wolfram|Alpha—and Wolfram Language—to ChatGPT. We’d <a href=\"https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/\">given “computational superpowers” to the AI</a>. </p>\n<p>ChatGPT was everywhere. And people kept asking me about it. And over and over again I ended up explaining things about it. So at the beginning of February 2023 I decided it’d be better for me just to write down once and for all what I knew. It took a little over a week (yes, I’m a fast writer)—and then I had an “<a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">explainer</a>” (that ran altogether to 76 pages) of ChatGPT. </p>\n<p>Partly it talked in general about how machine learning and neural nets work, and how ChatGPT in particular works. But what a lot of people wanted to know was not “how” but “why” ChatGPT works. Why was something like that possible? Well, in effect ChatGPT was <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#what-really-lets-chatgpt-work\">showing us a new science discovery</a>—about language. Everyone knows that there’s a certain syntactic grammar of language—like that, in English, sentences typically have the form noun-verb-noun. But what ChatGPT was showing us is that there’s also a <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#semantic-grammar-and-the-power-of-computational-language\">semantic grammar</a>—some pattern of rules for what words can be put together and make sense. </p>\n<p>I’ve thought about the <a href=\"https://writings.stephenwolfram.com/category/language-and-communication\">foundations of language</a> for a long time (which isn’t too surprising, given the four decades I’ve spent as a computational language designer). So in effect I was well primed to think about its interaction with ChatGPT. And it also helped that—as I’ll talk about below—one of my long-unfinished projects is precisely on a formal framework for capturing meaning that I call “<a href=\"https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/\">symbolic discourse language</a>”.</p>\n<p>In technology and other things I always like best situations where basically nothing is known, and one has to invent everything from scratch. And that’s what was happening for functionality based on LLMs in the middle of 2023. How would <a href=\"https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/\">LLM-based Wolfram Language functions</a> work? How would a <a href=\"https://writings.stephenwolfram.com/2023/06/prompts-for-work-play-launching-the-wolfram-prompt-repository/\">prompt repository</a> work? How would <a href=\"https://writings.stephenwolfram.com/2023/06/introducing-chat-notebooks-integrating-llms-into-the-notebook-paradigm/\">LLMs interact with notebooks</a>?</p>\n<p>Meanwhile, there was still lots of foment in the world about the “AI shock”. Before the arrival of the Physics Project in 2019—I’d been <a href=\"https://writings.stephenwolfram.com/2019/06/testifying-at-the-senate-about-a-i-selected-content-on-the-internet/\">quite involved</a> in <a href=\"https://writings.stephenwolfram.com/2016/10/a-short-talk-on-ai-ethics/\">AI philosophy</a>, AI ethics, etc. And in March 2023 I wrote a piece on “<a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/\">Will AIs Take All Our Jobs and End Human History—or Not?</a>” In the end—after all sorts of philosophical arguments, and an <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/#afterword-looking-at-some-actual-data\">analysis of actual historical data</a>—the answer was: “It’s Complicated”. But along the way computational irreducibility and the ruliad were central elements: limiting the controllability of AIs, allowing for an infinite frontier of invention, and highlighting the inevitable meaninglessness of everything in the absence of human choice. </p>\n<p>By this point (and actually, with remarkable speed) my explainer on ChatGPT had turned into a <a href=\"https://www.wolfram-media.com/products/what-is-chatgpt-doing-and-why-does-it-work/\">book</a>—that proved extremely popular (and now, for example, exists in over 10 languages). It was nice that people found the book useful—and perhaps it helped remove some of the alarming mystique of AI. But I couldn’t help noticing that of all the many things I’d written, this had been one of the fastest to write, yet it was garnering one of the largest readerships.</p>\n<p>One might have imagined that AI was pretty far from our Physics Project, the ruliad, etc. But actually it soon became clear that there were close connections, and that there were things to learn in both directions. In particular, I’d come to think of minds that work in different ways as occupying different positions in the ruliad. But how could one get intuition about what such minds would experience—or observe? Well, I realized, one could just look at generative AI. In July I wrote “<a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/\">Generative AI Space and the Mental Imagery of Alien Minds</a>”. I called this the “cats in hats piece”, because, yes, it has lots of pictures of (often bizarrely distorted) cats (in hats)—used as examples of what happens if one moves a mind around in rulial space. But despite the whimsy of the cats, this piece provided a surprisingly useful window into what for me has been a very longstanding question of how <a href=\"https://writings.stephenwolfram.com/2018/01/showing-off-to-the-universe-beacons-for-the-afterlife-of-our-civilization/\">other minds might perceive things</a>. </p>\n<p>And this fed quite directly into my piece on “<a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">Observer Theory</a>” in December 2023. Ever since things like Turing machines we’ve had a formal model for the process of computation. My goal was to do the same kind of thing for the process of observation. In a sense, computation constructs sequences of new things, say with time. Observation, on the other hand, equivalences things together, so they fit in finite minds. And just what equivalencing is done—by our senses, our measuring devices, our thinking—determines what our ultimate perceptions will be. Or, put another way, if we can characterize well enough what we’re like as observers, it’ll show us how we sample the ruliad, and what we’ll perceive the laws of physics to be.</p>\n<p>When I started the Physics Project I wasn’t counting on it having any applications for hundreds of years. But quite soon it became clear that actually there were going to be all sorts of near-term applications, particularly of the formalism of multicomputation. And every time one used that formalism one could get more intuition about features of the Physics Project, particularly related to quantum mechanics. I ended up writing a variety of “ruliological” pieces, all, as it happens, expanding on footnotes in <em>A New Kind of Science</em>. There was “<a href=\"https://www.wolframphysics.org/bulletins/2021/10/multicomputation-with-numbers-the-case-of-simple-multiway-systems/\" target=\"_blank\" rel=\"noopener\">Multicomputation with Numbers</a>” (October 2021), “<a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-multicomputational-systems/\">Games and Puzzles as Multicomputational Systems</a>” (June 2022) and “<a href=\"https://writings.stephenwolfram.com/2023/11/aggregation-and-tiling-as-multicomputational-processes/\">Aggregation and Tiling as Multicomputational Processes</a>” (November 2023). And in September 2023 there was also “<a href=\"https://writings.stephenwolfram.com/2023/09/expression-evaluation-and-fundamental-physics/\">Expression Evaluation and Fundamental Physics</a>”. </p>\n<p>Back around 1980—when I was working on SMP—I’d become interested in the theory of expression evaluation. And finally, now, with the Physics Project—and my work on combinators and metamathematics—four decades later I had a principled way to study it (potentially with immediate application in distributed computing and computational language design around that). And I could check off progress on another long-pending project.</p>\n<p>I give many talks, and do many podcasts and livestreams—essentially all unprepared. But in October 2023 I agreed to give a TED talk. And I just didn’t see any way to fit a reasonable snapshot of my activities into 18 minutes without preparation. How was I to coherently explain the Physics Project, the ruliad and computational language in such a short time? I called the talk “<a href=\"https://writings.stephenwolfram.com/2023/10/how-to-think-computationally-about-ai-the-universe-and-everything/\">How to Think Computationally about AI, the Universe and Everything</a>”. And I began with what for me was a new condensation: “Human language. Mathematics. Logic. These are all ways to formalize the world. And in our century there’s a new and yet more powerful one: computation.” </p>\n<p>Over the years I’d done all sorts of seemingly very different projects in science and in technology. But somehow it seemed like they were now all converging. Back in 1979, for example, I’d invented the idea of transformations for symbolic expressions as a foundation for computational language. But now—more than four decades later—our Physics Project was saying that those kinds of transformations (specifically on hypergraphs) were just what the “machine code of the universe” was made of. </p>\n<p>Since the 1980s I’d thought that computation was a useful paradigm with which to think about the world. But now our Physics Project and the ruliad were saying that it wasn’t just useful; it was the underlying paradigm of the world. For some time I’d been viewing our whole Wolfram Language effort as a way to provide a way to formalize computation for the purposes of both humans and machines. Four hundred years ago mathematical notation had streamlined mathematical thinking, allowing what became the mathematical sciences to develop. I saw what we were doing with our <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">computational language</a> as a way to streamline computational thinking, and allow “computational X” for all fields “X” to develop. </p>\n<p>I began to see computational thinking as a way to “humanize” the ruliad; to pick out those parts that are meaningful to humans. And I began to see computational language as the bridge between the power of raw computation, and the kinds of things we humans think about. </p>\n<p>But how did AI fit in? At the beginning of 2024, lots of people were still asking in effect “Can AI Solve Science?” So I <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/\">decided to analyze that</a>. I certainly didn’t expect AI to be able to “break computational irreducibility”. And it didn’t. Yes, it could automate much of what humans could do in a quick look. But formalized, irreducible computation: that was going to need computational language, not AI. </p>\n<p>It’s easy to be original in the computational universe: if you pick a rule at random, it’s overwhelmingly likely <a href=\"https://x.com/stephen_wolfram/status/1420206573096513539/photo/1\" target=\"_blank\" rel=\"noopener\">nobody’s ever looked at it before</a>. But will anyone care? They’ll care if in effect that part of the ruliad has been “colonized”; if there’s already a human connection to it. But what if you define some attribute that you want, then just “search out there” for a rule that exhibits it? That’s basically what biological evolution—or machine learning training—seems to do.</p>\n<p>And as a kind of <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/#exploring-spaces-of-systems\">off-hand note</a> I decided to just see if I could make a minimal model for that. <a href=\"https://content.wolfram.com/sw-publications/2020/07/approaches-complexity-engineering.pdf\" target=\"_blank\" rel=\"noopener\">I’d tried before—in the mid-1980s</a>. And in the 1990s when I was writing <em>A New Kind of Science</em> I’d become convinced that computational irreducibility was in a sense a <a href=\"https://www.wolframscience.com/nks/chap-8--implications-for-everyday-systems#sect-8-5--fundamental-issues-in-biology\">stronger force than adaptive evolution</a>, and that when complex behavior was seen in biology, it was computational irreducibility that should take most of the credit.</p>\n<p>But I decided to just do the experiment and see. And although computational irreducibility in a sense tells one to always “expect the unexpected”, in all these years I’ve never fully come to terms with that—and I’m still regularly surprised by what simple systems somehow “cleverly” manage to do. And so it was with <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">my minimal model of biological evolution</a>.</p>\n<p>I’d always wondered why biological evolution managed to work at all, why it didn’t “get stuck”, and how it managed to come up with the ornate “solutions” it did. Well, now I knew: and it turned out it was, once again, a story of computational irreducibility. And I’d managed to finish another project that I started in the 1980s.</p>\n<p>But then there was machine learning. And despite all the energy around it—as well as <a href=\"https://www.wolfram.com/language/core-areas/machine-learning/\">practical experience with it</a>—it didn’t seem like there was a good foundational understanding of what it was doing or why it worked. For a couple of years I’d been asking all the machine learning experts I ran into what they knew. But mostly they confirmed that, yes, it wasn’t well understood. And in fact several of them suggested that I’d be the best person to figure it out. </p>\n<p>So just a few weeks ago, starting with ideas from the biological evolution project, and mixing in some things I tried back in 1985, I decided to embark on exploring minimal models of machine learning. I just <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">posted the results last week</a>. And, yes, one seems to be able to see the essence of machine learning in systems vastly simpler than neural nets. In these systems one can visualize what’s going on—and it’s basically a story of finding ways to put together lumps of irreducible computation to do the tasks we want. Like stones one might pick up off the ground to put together into a stone wall, one gets something that works, but there’s no reason for there to be any understandable structure to it. </p>\n<p>Like so many of the projects I’ve done in the past five years, I could in principle have done this project much earlier—even in the 1980s. But back then I didn’t have the intuition, the tools or the intellectual confidence to actually dive in and get the project done. And what’s been particularly exciting over the past five years is that I can feel—and even very tangibly see—how what I can do has grown. With every project I’ve done I’ve further honed my intuition, developed more tools (both conceptual and practical), and built my intellectual confidence. Could I have gotten here earlier in my life? I don’t think so. I think to get to where I am now required the kind of journey I’ve taken through science, technology and the other things I’ve done. A living example of the phenomenon of computational irreducibility. </p>\n<h2 id=\"the-process-of-getting-things-done\">The Process of Getting Things Done</h2>\n<p>I started my career young—and usually found myself the “youngest person in the room”. But shockingly fast all those years whizzed by, and now I’m usually the “oldest person in the room”. But somehow I always still seem to feel like a young whippersnapper—not settled into some expected pattern, and “pushing for the future”. </p>\n<p>I’ve always done projects that are hard. Projects that many people thought were impossible. Projects that stretched my capabilities to the limit. And to do this has required a certain mixture of confidence and humility. Confidence that it’s worth me trying the project. Humility in not assuming that it’ll be easy for me. </p>\n<p>I’ve learned a lot of fields by now, and with them a lot of different ways of thinking. But somehow it’s never enough to make the projects I do easy. Somehow the projects are always far enough out on the frontier that I have to learn new things and new ways of thinking to succeed at them. And so there I am, often the only person in the room whose project isn’t somehow easy for them. And who still has to be pushing, whippersnapper style.</p>\n<p>At this point, a fair fraction of the projects I do are ones that I’ve thought about for a long time; a smaller fraction are opportunistic—coming into scope just now as a result of something I’ve done, or something that’s happened in the world at large. Before the past five years I had a lot of projects that had languished, often for decades. Yes, I thought they would be interesting, and I gradually collected information about them. But somehow I wasn’t quite in a place to tackle them.</p>\n<p>But now I feel quite differently. In the past five years, I’ve gone back and finished a fair fraction of all those languishing projects. And it’s been great. Without exception, the projects turned out to be richer and more interesting than I expected. Often I realized I really couldn’t have done them without the tools and ideas (and infrastructure) I now have. And—often to my great surprise—the projects turned out to have very direct connections to big themes around the ruliad, the Physics Project and, for that matter, computational language. </p>\n<p>Why was this happening? Partly it’s a tribute to the breadth of the computational (and now multicomputational) paradigm. But partly it has to do with the specific character of projects I was choosing—always seeking what seemed like the simplest, most foundational versions of things. </p>\n<p>I’ve done quite a few big projects in my life, many seemingly very different. But as I look back, I realize that all my projects have a certain overall pattern to them. They’re all about taking something that seems complicated, then drilling down to find the foundations of what’s going on, and then building up from these—often with considerable engineering-style effort. And the methods and tools I’ve developed have in a sense implicitly been optimized for this pattern of work. </p>\n<p>I suppose one gets used to the rhythm of it all. The time when one’s drilling down, slowly trying to understand things. The time when one’s doing all the work to build the big structure up. And yes, it’s all hard. But by now I know the signs of progress, and they’re always energizing to see. </p>\n<p>At any given time, I’ll have many projects gestating—often for years or decades. But once a project becomes active, it’s usually the only one I’m working on. And I’ll work on it with great intensity, pushing hard to keep going until it’s done. Often I’ll be working with other people, usually much younger than me. And I think it’s always a surprise that I’ll routinely be the one who works with the greatest intensity—every day, at all hours. </p>\n<p>I think I’m <a href=\"https://writings.stephenwolfram.com/2019/02/seeking-the-productive-life-some-details-of-my-personal-infrastructure/\">pretty efficient too</a>. Of course, it helps that I have a tool—Wolfram Language—that I’ve been building for decades to support me. And it helps that I’ve developed all kinds of practices around how I organize code and notebooks I create, and how I set up my process of writing about things. Of course, it also helps that I have very capable people around me to make suggestions, explore additional directions, fill in details, check things, and get my write-ups produced and published.</p>\n<p>As I have <a href=\"https://writings.stephenwolfram.com/2019/02/seeking-the-productive-life-some-details-of-my-personal-infrastructure/\">written about elsewhere</a>, my life is in many ways set up to be quite simple and routine. I get up at the same time every day, eat the same thing for breakfast, and so on. But in a sense this frees me to concentrate on the intellectual things I’m doing—which are different every day, often in unexpected ways. </p>\n<p>But how is it that I even get the time to do all these intellectual things? After all, I am—as I have been for the past 38 years—the CEO of a <a href=\"https://www.wolfram.com/\">very active tech company</a>. Two things I think help (in addition, of course, to the fact that I have such a great long-term team at the company). First, organization. And second, resolve. Every day I’ll have <a href=\"https://writings.stephenwolfram.com/2012/03/the-personal-analytics-of-my-life/\">tightly scheduled meetings</a> over the course of the working day. (And there are lots of details to this. I get up in the late morning, then do my first two meetings while walking, and so on.) But somehow—mostly on evenings and weekends—I find time to work intensely on my intellectual projects.</p>\n<p>It’s not as if I ignore everything else in the world. But I do have a certain drive—and resolve—that fills any time available with my projects, and somehow seems to succeed in getting them done. (And, yes, there are many optimizations in the details of my life, saving me all sorts of time. And it probably helps that I’ve been a work-from-home CEO now for 33 years.)</p>\n<p>One might have thought that CEOing would greatly detract from being able to do intellectual work. But I find the exact opposite. Because in my experience the discipline of strategy and decision making (as well as communicating thoughts and ideas to other people) that comes with CEOing is critical to being able to do incisive intellectual work. And, by the way, the kind of thinking that goes with intellectual work is also incredibly valuable in being an effective CEO. </p>\n<p>There’s another critical part to my “formula”. And that has to do with exposition. For me, the exposition of a project is an integral part of the project. Part of it is that the very definition of the question is often one of the most important parts of a project. But more than that, it’s through exposition that I find I really understand things. It takes a certain discipline. It can be easy enough to make some highfalutin technical statement. But can one grind it down into truly simple pieces that one can immediately understand? Yes, that means other people will be able to understand it too. But for me, what’s critical is that that’s the way I can tell if I’m getting things right. And for me the exposition is what in the end defines the backbone of a project. </p>\n<p>Normally I write quickly, and basically without revision. But whenever there’s a piece I’m finding unduly hard to write I know that’s where I’m muddled, and need to go back and understand what’s going on. Some of my projects (like creating this piece, for example) end up being essentially “pure writing”. But most are deeply computational—and full of computer experiments. And just as I put a lot of effort into making written exposition clear, I do the same for computational language, and for pictures. Indeed, many of my projects are in large measure driven by pictures. Usually these are what one can think of as “algorithmic diagrams”—created automatically with a <a href=\"https://writings.stephenwolfram.com/2017/11/what-is-a-computational-essay/\">structure optimized for exposition</a>.</p>\n<p>And the pictures aren’t just useful for presenting what I’ve done; they’re also critical to my own efforts to figure things out. And I’ve learned that it’s important to get the presentational details of pictures right as early as possible in a project—to give myself the best chance to notice things. </p>\n<p>Often the projects I do require exploring large numbers of possible systems. And somehow with great regularity this leads to me ending up looking at <a href=\"https://www.wolframscience.com/nks/p55--more-cellular-automata/\">large arrays of little pictures</a>. Yes, there’s a lot of “looking” <a href=\"https://www.wolframphysics.org/technical-introduction/typical-behaviors/random-rules-and-overall-classification-of-behavior/#p-144\" target=\"_blank\" rel=\"noopener\">that can be automated</a>. But in the end computational irreducibility means there’ll always be the unexpected, that I basically have to see for myself. </p>\n<p>A great thing about the Wolfram Language is that it’s been very stable ever since it was first released. And that means that I can take notebooks even from the 1980s and immediately run them today. And, yes, given all the “old” projects I’ve worked on in the past five years, that’s been very important. </p>\n<p>But in addition to being very stable, the Wolfram Language is also very self contained—and very much <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">intended to be readable by humans</a>. And the result is something that I’ve found increasingly important: every computational picture in everything I write has Wolfram Language code “behind it”, that you can get by clicking. All the time I find myself going back to previous things I’ve written, and picking up <a href=\"https://reference.wolfram.com/language/ref/ClickToCopy.html\">click-to-copy</a> code to run for some new case, or use as the basis for something new I’m doing. </p>\n<p>And of course that click-to-copy code is open for anyone to use. Not only for its “computational content”, but also for the often-elaborate visuals it implements.</p>\n<p>Most of my writings over the past five years have been about new basic science. But interspersed with this—along with pieces about technology and about philosophy—are <a href=\"https://writings.stephenwolfram.com/category/historical-perspectives/\">pieces about history</a>. And in fact many of my scientific pieces have had extensive historical sections as well. </p>\n<p>Why do I put such effort into history? Partly I just find it fun to figure out. But mostly it’s to contextualize my understanding of things. Particularly in the past five years I’ve ended up working on a whole sequence of projects that are in a sense about changing longstanding directions in science. And to feel confident about making such changes, one has to know why people went in those directions in the first place. And that requires studying history.</p>\n<p>Make no mistake: history—or at least good history—is hard. Often there’ll be a standard simple story about how some discovery was suddenly made, or how some direction was immediately defined. But the real story is usually much more complicated—and much more revealing of the true intellectual foundations of what was figured out. Almost never did someone discover something “one day”; almost always it took many years to build up the conceptual framework so that “one day” the key thing could even be noticed. </p>\n<p>When I do history I always make a big effort to look at the original documents. And often I realize that’s critical—because it’s only with whatever new understanding I’ve developed that one would stand a chance of correctly interpreting what’s in the documents. And even if one’s mainly interested in the history of ideas, I’ve always found it’s crucial to also understand the people who were involved with them. What was their motivation? What was their practical situation? What kinds of things did they know about? What was their intellectual style in thinking about things?</p>\n<p>It has helped me greatly that I’ve had my own experiences in making discoveries—that gives me an intuition for how the process of discovery works. And it also helps that I’ve had my fair share of “worldly” experiences. Still, often it’s at first a mystery how some idea developed or some discovery got made. But my consistent experience is that with enough effort one can almost always solve it. </p>\n<p>Particularly for the projects I’ve done in recent years, it often leaves me with a strange feeling of connection. For in many cases I find out that the things I’ve now done can be viewed as direct follow-ons to ideas that were thought about a century or more ago, and for one reason or another ignored or abandoned since. </p>\n<p>And I’m then usually left with a strong sense of responsibility. An idea that was someone’s great achievement had been buried and lost to the world. But now I have found it again, and it rests on me to bring it into the future.</p>\n<p>In addition to writing about “other people’s history”, I’ve also been writing quite a bit about my own history. And in the last few years I’ve made a point of explaining my personal history around the science—and technology—I describe. In doing this, it helps a lot that I have <a href=\"https://writings.stephenwolfram.com/2019/02/seeking-the-productive-life-some-details-of-my-personal-infrastructure/#archiving-and-searching\">excellent personal archives</a>—that routinely let me track to within minutes <a href=\"https://writings.stephenwolfram.com/2024/06/ruliology-of-the-forgotten-code-10/\">discoveries I made even four decades ago</a>. </p>\n<p>My goal in describing my own history is to help other people contextualize things I write about. But I have to say that time and time again I’ve found the effort to piece together my own history extremely valuable just for me. As I go through life, I try to build up a repertoire of patterns for how things I do fit together. But often those patterns aren’t visible at the time. And it takes going back—often years later—to see them. </p>\n<p>I do the projects I do first and foremost for myself. But I’ve always liked the idea that other people can get their own pleasure and benefit from my projects. And—basically starting with the Physics Project—I’ve tried to open to the world not just the results of my projects, but the process by which they’re done. </p>\n<p>I post my <a href=\"https://www.wolframphysics.org/archives/index/\" target=\"_blank\" rel=\"noopener\">working notebooks</a>. Whenever practical I <a href=\"https://livestreams.stephenwolfram.com/\" target=\"_blank\" rel=\"noopener\">livestream</a> my working meetings. And, perhaps taking things to an extreme, I record even my own solitary work, posting it in “<a href=\"https://livestreams.stephenwolfram.com/category/personal-video-worklogs/\" target=\"_blank\" rel=\"noopener\">video work logs</a>”. (Except I just realized I forgot to record the writing I’m doing right now!) </p>\n<p>A couple of years before the Physics Project I actually also <a href=\"https://writings.stephenwolfram.com/2017/12/what-do-i-do-all-day-livestreamed-technology-ceoing/\">opened up my technology development activities</a>—livestreaming our <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\" target=\"_blank\" rel=\"noopener\">software design reviews</a>, in the past five years 692 hours of them. (And, yes, I put a lot of work and effort into designing the Wolfram Language!)</p>\n<p>At the beginning of the pandemic I thought: “There are all these kids out of school. Let me try to do a little bit of public service and livestream something about science and technology for them.” And that’s how I started my “<a href=\"https://livestreams.stephenwolfram.com/category/science-technology-qa-for-kids-and-others\" target=\"_blank\" rel=\"noopener\">Science & Technology Q&A for Kids & Others</a>” livestreams, that I’ve now been doing for four and a half years. Along the way, I’ve added “<a href=\"https://livestreams.stephenwolfram.com/category/history-of-science-and-technology-qa\" target=\"_blank\" rel=\"noopener\">History of Science & Technology Q&A</a>”, “<a href=\"https://livestreams.stephenwolfram.com/category/future-of-science-technology-qa/\" target=\"_blank\" rel=\"noopener\">Future of Science & Technology Q&A</a>”, and “<a href=\"https://livestreams.stephenwolfram.com/category/business-innovation-and-managing-life-qa\" target=\"_blank\" rel=\"noopener\">Business, Innovation & Managing Life Q&A</a>”. Altogether I’ve done 272 hours of these, that have generated 376 <a href=\"https://podcasters.spotify.com/pod/show/stephenwolfram\" target=\"_blank\" rel=\"noopener\">podcast episodes</a>.</p>\n<p>Twice a week I sit down in front of a camera, watch the feed of questions, and try to answer them. It’s always off the cuff, completely unprepared. And I find it a great experience. I can tell that over the time I’ve been doing this, I’ve become a better and more fluent explainer, which no doubt helps my written exposition too. Often in answering questions I’ll come up with a new way to explain something, that I’ve never thought of before. And often there’ll be questions that make me think about things I’ve never thought about at all before. Indeed, several of my recent projects actually got started as a result of questions people asked. </p>\n<p>When I was younger I always just wanted to get on with research, create things, and so on; I wasn’t interested in education. But as I’ve gotten older I’ve come to really like education. Partly it’s because I feel I learn a lot myself from it, but mostly it’s because I find it fulfilling to use what I know and try to help people develop. </p>\n<p>I’ve always been interested in people—a useful attribute in running a talent-rich company for four decades. (I’m particularly interested in how people develop through their lives—leading me recently, for example, to organize a 50-year reunion for my elementary school class.) I’ve had a <a href=\"https://writings.stephenwolfram.com/2019/08/fifty-years-of-mentoring/\">long-time “hobby” of mentoring CEOs and kids</a> (both being categories of people who tend to believe that anything is possible). </p>\n<p>But my main educational efforts are concentrated in a few weeks of the year when we do our <a href=\"https://education.wolfram.com/summer-school\">Wolfram Summer School</a> (started in 2003) and our <a href=\"https://education.wolfram.com/summer-research-high-school/\">Wolfram High School Summer Research Program</a> (started in 2012). All the students in these programs (775 of them over the past five years) do an original project, and one of my jobs is to come up with what all these projects should be. Over the course of the year I’ll accumulate ideas—though rather often when I actually meet a student I’ll invent something new. </p>\n<p>I obviously do plenty of projects myself. But it’s always an interesting—and invigorating—experience to see so many projects get done with such intensity at our summer programs. Plus, I get lots of extra practice in framing projects that helps when I come to frame my own projects.</p>\n<p>At this point, I’ve spent years trying to organize my life to optimize it for what I want to get out of it. I need long stretches of time when I can concentrate coherently. But I like having a diversity of activities, and I’m pretty sure I wouldn’t have the energy and effectiveness I do without that. Over the years, I’ve added in little pieces. Like my weekly virtual sessions where I “do my homework” with a group of kids, working on something that I need to get done, but that doesn’t quite fit elsewhere. Or my weekly sessions with local kids, talking about things that make me and them think. Or, for that matter, my “call while driving” list of calls it’s good to make, but wouldn’t usually quite get the priority to happen. </p>\n<p>Doing all the things I do is hard work. But it’s what I want to do. Yes, things can drag from time to time. But at this point I’m so used to the rhythm of projects that I don’t think I notice much. And, yes, I work basically every hour of every day I can. Do I have hobbies? Well, back when I was an academic, business was my main “hobby”. When I started CEOing, science became a “hobby”. Writing. Education. Livestreaming. These were all “hobbies” too. But somehow one of the patterns of my life is that nothing really stays quite as a “true hobby”.</p>\n<h2 id=\"whats-next\">What’s Next?</h2>\n<p>The past five years have not only been my most productive ever, but they’ve also built more “productivity momentum” than I’ve had before. So, what’s next? I have a lot of projects currently “in motion”, or ready to “get into motion”. Then I have many more that are in gestation, for which the time may finally have come. But I know there’ll also be surprises: projects that suddenly occur to me, or that I suddenly realize are possible. And one of the great challenges is to be in a position to actually jump into such things. </p>\n<p>It has to be said that there’s always a potentially complicated tradeoff. To what extent should one “tend” the things one’s already done, and to what extent should one do new things? Of course, there are some things that are never “done”—like the Wolfram Language, which I started building 38 years ago, and still (energetically) work on every day. Or the Physics Project, where there’s just so much to figure out. But one of the things that’s worked well in most of the basic science projects I’ve done in the past five years or is that once I’ve written my piece about the project, I can usually consider the project “done for now”. It always takes a lot of effort to get a project to the point where I can write about it. But I work hard to make sure I only have to do it once; that I’ve “picked the low-hanging fruit”, so I don’t feel I have to come back “to add a little more”.</p>\n<p>I put a lot of effort into the pieces I write about my projects. And I also give talks, do interviews, etc. (about 500 altogether in the past five years). But I certainly don’t “market” my efforts as much as I could. It’s a decision I’ve made: that at this point in my life—particularly with the burst of productivity I’m experiencing—I want to spend as much of my time as possible doing new things. And so I need to count on others to follow up and spread knowledge about what I’ve done, whether in the academic world, on Wikipedia, the web, etc. (And, yes, pieces I write and the pictures they contain are <a href=\"https://writings.stephenwolfram.com/terms/\">set up to be immediately reproducible wherever appropriate</a>.)</p>\n<p>OK, so what specific new things are currently in my pipeline? Well, there’s lots of science (and related intellectual things). And there’s also lots of technology. But let’s talk about science first. </p>\n<p>A big story is the Physics Project—where there’s a lot to be done, in many different directions. There’s foundational theory to be developed. And there are experimental implications to be found.</p>\n<p>It’d be great if we could find experimental evidence of the discreteness of space, or maximum entanglement speed, or a host of other unexpected phenomena in our models. A century or so ago it was something of a stroke of luck that atoms were big enough that they could be detected. And we don’t know if the discreteness of space is something we’ll be able to detect now—or only centuries from now. </p>\n<p>There are phenomena—particularly associated with black holes—that might effectively serve as powerful “spacetime microscopes”. And there are phenomena like dimension fluctuations that could potentially show up in a variety of astrophysical settings. But one direction I’m particularly interested in exploring is what one might call “spacetime heat”—the effect of detailed microscopic dynamics in the hypergraph that makes up spacetime. Could “dark matter”, for example, not be “matter” at all, but instead be associated with spacetime heat?</p>\n<p>Part of investigating this involves building practical simulation software to investigate our models on as large a scale as possible. And part of it involves “good, old-fashioned physics”, figuring out how to go from underlying foundational effects to observable phenomena. </p>\n<p>And there’s a foundational piece to this too. How does one set up mathematics—and mathematical physics—when one’s starting from a hypergraph? A traditional manifold is ultimately built up from Euclidean space. But what kind of object is the limit of a hypergraph? To understand this, we need to construct what I’m calling infrageometry—and infracalculus alongside it. Infrageometry—as its name suggests—starts from something lower level than traditional geometry. And the challenge is in effect to build a “21st century Euclid”, then Newton, etc.—eventually finding generalizations of things like differential geometry and algebraic topology that answer questions like what 3<img style=\"margin-bottom: -8px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2024/08/one-quarter-fraction.png\" alt=\"\" width=\"9\" height=\"24\" />-dimensional curvature tensors are like, or how we might distinguish local gauge degrees of freedom from spatial ones in a limiting hypergraph.</p>\n<p>Another direction has to do with particles—like electrons. The fact is that existing quantum field theory in a sense only really deals with particles indirectly, by thinking of them as perturbations in a field—which in turn is full of (usually unobservable) zero-point fluctuations. In our models, the structure of everything—from spacetime up—is determined by the “fluctuating” structure of the underlying hypergraph (or, more accurately, by the whole multiway graph of “possible fluctuations”). And what this suggests is that there’s in a sense a much lower level version of the Feynman diagrams we use in quantum field theory and where we can discuss the “effect of particles” without ever having to say exactly what a particle “is”.</p>\n<p>I must say that I expected we’d have to know what particles were even to talk about energy. But it turned out there was a “bulk” way to do that. And maybe similarly there’s an indirect way to talk about interactions between particles. My guess is that in our model particles are structures a bit like black holes—but we may be able to go a very long way without having to know the details.</p>\n<p>One of the important features of our models is that quantum mechanics is “inevitable” in them. And one of the projects I’m hoping to do is to finally “really understand quantum mechanics”. In general terms, it’s connected to the way branching observers (like us) perceive branching universes. But how do we get intuition for this, and what effects can we expect? Several projects over the past years (like <a href=\"https://www.wolframphysics.org/bulletins/2021/02/multiway-turing-machines/\" target=\"_blank\" rel=\"noopener\">multiway Turing machines</a>, <a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-multicomputational-systems/\">multiway games</a>, <a href=\"https://writings.stephenwolfram.com/2023/11/aggregation-and-tiling-as-multicomputational-processes/\">multiway aggregation</a>, etc.) I’ve done in large part to bolster my intuition about branchial space and quantum mechanics. </p>\n<p>I first <a href=\"https://x.com/stephen_wolfram/status/1370144700003463168\" target=\"_blank\" rel=\"noopener\">worked on quantum computers back in 1980</a>. And at the time, I thought that the measurement process (whose mechanism isn’t described in the standard formalism of quantum mechanics) would be a big problem for them. Years have gone by, and enthusiasm for quantum computers has skyrocketed. In our models there’s a rather clear picture that inside a quantum computer there are “many threads of history” that can in effect do computations in parallel. But for an observer like us to “know what the answer is” we have to knit those threads together. And in our models (particularly with my observer theory efforts) we start to be able to see how that might happen, and what the limitations might be.</p>\n<p>Meanwhile, in the world at large there are all sorts of experimental quantum computers being built. But what are their limitations? I have a suspicion that there’s some as-yet-unknown fundamental physics associated with these limitations. It’s like building telescopes: you polish the mirror, and keep on making engineering tweaks. But unless you know about diffraction, you won’t understand why your resolution is limited. And I have a slight hope that even existing results on quantum computers may be enough to see limitations perhaps associated with <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#branchial-motion-and-the-entanglement-horizon\">maximum entanglement speed</a> in our models. And the way our models work, knowing this speed, you can for example <a href=\"https://www.wolframphysics.org/technical-introduction/potential-relation-to-physics/units-and-scales/\" target=\"_blank\" rel=\"noopener\">immediately deduce</a> the discreteness scale of space. </p>\n<p>Back in 1982, I and another physicist wrote two papers on “Properties of the Vacuum”. <a href=\"https://content.wolfram.com/sw-publications/2020/07/properties-vacuum-mechanical-thermodynamic.pdf\" target=\"_blank\" rel=\"noopener\">Part 1 was mechanical properties</a>. <a href=\"https://content.wolfram.com/sw-publications/2020/07/properties-vacuum-electrodynamic.pdf\" target=\"_blank\" rel=\"noopener\">Part 2 was electrodynamic</a>. We announced a part 3, on gravitational properties. But we never wrote it. Well, finally, it looks as if our Physics Project shows us how to think about such properties. So perhaps it’s time to finally write “Part 3”, and respond to all those people who sent preprint request cards for it four decades ago. </p>\n<p>One of the great conclusions of our Physics Project—and the concept of the ruliad—is that we have the laws of physics we do because we are observers of the kind we are. And just knowing very coarsely about us as observers seems to already imply the major laws of twentieth century physics. And to be able to say more, I think we need more characterization of us as observers. And my guess is, for example, that some feature of us that we probably consider completely obvious is what leads us to perceive space as (roughly) three dimensional. And indeed I increasingly suspect that the whole structure of our Physics Project can be derived—a bit like early derivations of special relativity—from certain axiomatic assumptions about our nature as observers, and fundamental features of computation.</p>\n<p>There’s plenty to do on our Physics Project, and I’m looking forward to making progress with all of it. But the ideas of the Physics Project—and multicomputation in general—<a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/#potential-application-areas\">apply to lots of other fields too</a>. And I have many projects planned on these.</p>\n<p>Let’s talk first about chemistry. I never found chemistry interesting as a kid. But as we’ve added <a href=\"https://www.wolfram.com/language/core-areas/chemistry/\">chemistry functionality in the Wolfram Language</a>, I’ve understood more about it, and why it’s interesting. And I’ve also followed molecular computing since the 1980s. And now, largely inspired by thinking about multicomputation, I’ve become very interested in what one might call the foundations of chemistry. Actually, what I’m most interested in is what I’m calling “subchemistry”. I suppose one can think of it as having a similar kind of relation to chemistry as infrageometry has to geometry. </p>\n<p>In ordinary chemistry, one thinks about reactions between different species of molecules. And to calculate rates of reactions, one multiplies concentrations of different species, implicitly assuming that there’s perfect randomness in which specific molecules interact. But what if one goes to a lower level, and starts talking about the interactions not of species of molecules, but individual molecules? From our Physics Project we get the idea of making causal graphs that represent the causal relations between different specific interaction events. </p>\n<p>In a gas the assumption of molecular-level randomness will probably be pretty good. But even in a liquid it’ll be more questionable. And in more exotic materials it’ll be a completely different story. And I suspect that there are “subchemical” processes that can potentially be important, perhaps in a sense finding a new “slice of computational reducibility” within the general computational irreducibility associated with the Second Law.</p>\n<p>But the most important potential application of subchemistry is in biology. If we look at biological tissue, a basic question might be: “What phase of matter is it?” One of the major takeaways from molecular biology in the last few decades has been that in biological systems, molecules (or at least large ones) are basically never just “bouncing around randomly”. Instead, their motion is typically carefully orchestrated. </p>\n<p>So when we look at biological tissue—or a biological system—we’re basically seeing the result of “bulk orchestration”. But what are the laws of bulk orchestration? We don’t know. But I want to find out. I think the “<a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/#class-4-and-the-mechanoidal-phase\">mechanoidal phase</a>” that I identified in studying the Second Law is potentially a good test case. </p>\n<p>If we look at a microprocessor, it’s not very useful to describe it as “containing a gas of electrons”. And similarly, it’s not useful to describe a biological cell as “being liquid inside”. But just what kind of theory is needed to have a more useful description we don’t know. And my guess is that there’ll be some new level of abstraction that’s needed to think about this (perhaps a bit like the new abstraction that was needed to formulate information theory).</p>\n<p>Biology is not big on theory. Yes, there’s natural selection. And there’s the digital nature of biomolecules. But mostly biology has ended up just accumulating vast amounts of data (using ever better instrumentation) without any overarching theory. But I suspect that in fact there’s another foundational theory to be found in biology. And if we find it, a lot of the data that’s been collected will suddenly fall into place.</p>\n<p>There’s the “frankly molecular” level of biology. And there’s the more “functional” level. And I was surprised recently to be able to find a very minimal model that seems to capture <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">“functional” aspects of biological evolution</a>. It’s a surprisingly rich model, and there’s much more to explore with it, notably about how different “ideas” get propagated and developed in the process of adaptive evolution—and what kinds of tree-of-life-style branchings occur. </p>\n<p>And then there’s the question of <a href=\"https://www.wolframscience.com/nks/notes-12-10--self-reproduction/\">self replication</a>—a core feature of biology. Just how simple a system can exhibit it in a “biologically relevant way”? I had thought that self replication was “just relevant for biology”. But in thinking about the problem of observers in the ruliad, I’ve come to realize that it’s also relevant at a foundational level there. It’s no good to just have one observer; you have to have a whole “rulial flock” of similar ones. And to get similar ones you need something like self replication. </p>\n<p>Talking of “societies of observers” brings me to another area I want to study: economics. How does a coherent economic system emerge from all the microscopic transactions and other events in a society? I suspect it’s a story that’s in the end similar to the theories we’ve studied in physics—from the emergence of bulk properties in fluids, to the emergence of continuum spacetime, and so on. But now in economics we’re dealing not with fluid density or metric, but instead with things like price. I don’t yet know how it will work out. Maybe computational reducibility will be associated with value. Maybe computational irreducibility will be what determines robustness of value. But I suspect that there’s a way of thinking about “economic observers” in the ruliad—and figuring out what “natural laws” they’ll “inevitably observe”. And maybe some of those natural laws will be relevant in thinking about the kind of questions we humans care about in economics.</p>\n<p>It’s rather amazing in how many different areas one seems to be able to apply the kind of approach that’s emerged from the Physics Project, the ruliad, etc. One that I’ve very <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">recently tackled is machine learning</a>. And in my effort to understand its foundations, I’ve ended up coming up with some very minimal models. My purpose was to understand the essence of machine learning. But—somewhat to my surprise—it looks as if these minimal models can actually be practical ways to do machine learning. Their hardware-level tradeoffs are somewhat different. But—given my interest in practical technology—I want to see if one can build out a practical machine-learning framework that’s based on these (fundamentally discrete) models. </p>\n<p>And while I’m not currently planning to investigate this myself, I suspect that the approach I’ve used to study machine learning can also be applied to neuroscience, and perhaps to linguistics. And, yes, there’ll probably be a lot of computational irreducibility in evidence. And once again one has to hope that the pockets of computational reducibility that exist will give rise to “natural laws” that are useful for what we care about in these fields. </p>\n<p>In addition to these “big” projects, I’m also hoping to do a variety of “smaller” projects. Many I started decades ago, and in fact mentioned in <em>A New Kind of Science</em>. But now I feel I have the tools, intuition and intellectual momentum to finally finish them. <a href=\"https://www.wolframscience.com/nks/p130--recursive-sequences/\">Nestedly recursive functions</a>. <a href=\"https://www.wolframscience.com/nks/p221--systems-based-on-constraints/\">Deterministic random tilings</a>. <a href=\"https://www.wolframscience.com/nks/notes-12-8--undecidability-in-natural-systems/\">Undecidability in the three-body problem</a>. <a href=\"https://www.wolframscience.com/nks/notes-6-8--structures-in-the-game-of-life/\">“Meta-engineering” in the Game of Life</a>. These might on their own seem esoteric. But my repeated experience—particularly in the past five years—is that by solving problems like these one builds examples and intuition that have surprisingly broad application.</p>\n<p>And then there are history projects. Just what did happen to theories of discrete space in the early twentieth century (and how close did people like Einstein get to the ideas of our Physics Project)? What was “ancient history” of neural nets, and why did people come to assume they should be based on continuous real numbers? I fully expect that as I investigate these things, I’ll encounter all sorts of “if only” situations—where for example some unpublished note languishing in an archive (or attic) would have changed the course of science if it had seen the light of day long ago. And when I find something like this, it’s yet more motivation to actually finish those projects of mine that have been languishing so long in the filesystem of my computer. </p>\n<p>There’s a lot I want to do “down in the computational trenches”, in physics, chemistry, biology, economics, etc. But there are also things at a more abstract level in the ruliad. There’s more to study about metamathematics, and about how mathematics that we humans care about can emerge from the ruliad. And there are also foundational questions in computer science. P vs. NP, for example, can be formulated as an essentially geometric problem in the ruliad—and conceivably there are mathematical methods (say from higher category theory) that might give insight into it. </p>\n<p>Then there are questions about hyperruliads and hyporuliads. In a hyperruliad that’s based on hypercomputation, there will be hyperobservers. But is there a kind of “rulial relativity” that makes their perception of things just the same as “ordinary observers” in the ordinary ruliad? A way to get some insight into this may be to study hyporuliads—versions of the ruliad in which there are only limited levels of computation possible. A bit like the way a spacelike singularity associated with a black hole supports only limited time histories, or a decidable axiomatic theory supports only proofs of limited length, there will be limitations in the hyporuliad. And by studying them, there’s a possibility that we’ll be able to see more about issues like what kinds of mathematical axioms can be compatible with observers like us. </p>\n<p>It’s worth commenting that our Physics Project—and the ruliad—have all sorts of connections and resonances with long-studied ideas in philosophy. “Didn’t Kant talk about that? Isn’t that similar to Leibniz?”, etc. I’ve wanted to try to understand these historical connections. But while I’ve done a lot of work on the historical development of ideas, the ideas in question have tended to be more focused, and more tied to concrete formalism than they usually are in philosophy. “Did Kant actually mean that, or something completely different?” You might have to understand all his works to know. And that’s more than I think I can do.</p>\n<p>I invented the concept of the ruliad as a matter of science. But it’s now clear that the ruliad has all sorts of connections and resonances not only with philosophy but also with theology. Indeed, in a great many belief systems there’s always been the idea that somehow in the end “everything is one”. In cases where this gets slightly more formalized, there’s often some kind of combinatorial enumeration involved (think: <em>I Ching</em>, or various versions of “counting the names of God”). </p>\n<p>There are all sorts of examples where long-surviving “ancient beliefs” end up having something to them, even if the specific methods of post-1600s science don’t have much to say about them. One example is the notion of a soul, which we might now see as an ancient premonition of the modern notion of abstract computation. And whenever there’s a belief that’s ancient, there’s likely to have been lots of thinking done around it over the millennia. So if we can, for example, see a connection to the ruliad, we can expect to leverage that thinking. And perhaps also be able to provide new input that can refine the belief system in interesting and valuable ways. </p>\n<p>I’m always interested in different viewpoints about things—whether from science, philosophy, theology, wherever. And an extreme version of this is to think about how other “alien” minds might view things. Nowadays I think of different minds as effectively being at different places in the ruliad. Humans with similar backgrounds have minds that are close in rulial space. Cats and dogs have minds that are further away. And the weather (with <a href=\"https://www.wolframscience.com/nks/p845--historical-perspectives/\">its “mind of its own”</a>) is still further. </p>\n<p>Now that we have AIs we potentially have a way to study the correspondence—and communication—between “different minds”. I looked at one aspect of this in my <a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/\">“cats” piece</a>. But my <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/\">recent work on the foundations of machine learning</a> suggests a broader approach, that can also potentially tell us things about the fundamental character of language, and about how it serves as a medium that can “<a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#communicating-across-rulial-space\">transport thoughts</a>” from one mind to another.</p>\n<p>Many non-human animals seem to have at least some form of language—though mostly in effect just a few standalone words. But pretty unquestionably the greatest single invention of our species is language—and particularly compositional language where words and phrases can fit together in an infinite number of ways. But is there something beyond compositional language? And, for example, where might we get if our brains were bigger?</p>\n<p>With the 100 billion neurons in our brains, we seem to be able to handle about 50,000 words. If we had a trillion neurons we’d probably be able to handle more words (though perhaps more slowly), in effect letting us describe more things more easily. But what about something fundamentally beyond compositional language? Something perhaps “higher order”? </p>\n<p>With a word we are in effect conflating all instances of a certain concept into a single object that we can then work with. But typically with ordinary words we’re dealing with what we might call “static concepts”. So what about “ways of thinking”, or paradigms? They’re more like active, functional concepts. And it’s a bit like dogs versus us: dogs deal with a few standalone words; we “package” those together into whole sentences and beyond. And at the next level, we could imagine in effect packaging things like generators of meaningful sentences.</p>\n<p>Interestingly enough, we have something of a preview of ideas like this—in computational language. And this is one of those places where my efforts in science—and philosophy—start to directly intersect with my efforts in technology.</p>\n<p>The foundation of the Wolfram Language is the idea of representing everything in computational terms, and in particular in symbolic computational terms. And one feature of such a representation is that it can encompass both “data” and “code”—i.e. both things one might think about, and ways one might think about them. </p>\n<p>I first started building Wolfram Language as a practical tool—though one very much informed by my foundational ideas. And now, four decades later, the Wolfram Language has emerged as the largest single project of my life, and something that, yes, I expect to always put immense effort into. It wasn’t long ago that we finally finished my 1991 to-do list for Wolfram Language—and we have many projects running now that will take years to complete. But the <a href=\"https://writings.stephenwolfram.com/2020/10/our-mission-and-the-opportunity-of-artifacts-from-the-future/\">mission has always remained the same</a>: to take the concept of computation and apply it as broadly as possible, through the medium of computational language. </p>\n<p>Now, however, I have some additional context for that—viewing computational language as a bridge from what we humans think about to what’s possible in the computational universe. And this helps in framing some of the ways to expand the foundations of our computational language, for example to multicomputation, or to hypergraph-based representations. It also helps in understanding the character of current AI, and how it needs to interact with computational language.</p>\n<p>In the Wolfram Language we’ve been steadily trying to create a representation for everything. And when it comes to definitive, objective things we’ve gotten a long way. But there’s more than that in everyday discourse. For example, I might say “I’m going to drink a glass of orange juice.” Well, we do just fine at <a href=\"https://www.wolfram.com/language/12/food-and-nutrition-entities/\">representing “a glass of orange juice”</a> in the Wolfram Language, and we can compute lots of things—like nutrition content—about it. But what about “I’m going to drink…”? For that we need something different. </p>\n<p>And, actually, I’ve been thinking for a shockingly long time about what one might need. I first considered the question in the early 1980s, in connection with “extending SMP to AI”. I learned about the attempts to make “philosophical languages” in the 1600s, and about some of the thinking around modern conlangs (constructed languages). Something that always held me back, though, was use cases. Yes, I could see how one could use things like this for tasks like customer service. But I wasn’t too excited about that. </p>\n<p>But finally there was blockchain, and with it, smart contracts. And around 2015 I started thinking about how one might represent contracts in general not in legalese but in some precise computational way. And the result was that I began to <a href=\"https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/\">crispen my ideas about what I called “symbolic discourse language”</a>. I thought about how this might relate to questions like a “constitution for AIs” and so on. But I never quite got around to actually starting to design the specifics of the symbolic discourse language.</p>\n<p>But then along came LLMs, together with my theory that their success had to do with a “semantic grammar” of language. And finally now we’ve launched a serious project to build a symbolic discourse language. And, yes, it’s a difficult language design problem, deeply entangled with a whole range of foundational issues in philosophy. But as, by now at least, the world’s most experienced language designer (for better or worse), I feel a responsibility to try to do it. </p>\n<p>In addition to language design, there’s also the question of making all the various “symbolic calculi” that describe in appropriately coarse terms the operation of the world. Calculi of motion. Calculi of life (eating, dying, etc.). Calculi of human desires. Etc. As well as calculi that are directly supported by the computation and knowledge in the Wolfram Language.</p>\n<p>And just as LLMs can provide a kind of conversational linguistic interface to the Wolfram Language, one can expect them also to do this to our symbolic discourse language. So the pattern will be similar to what it is for Wolfram Language: the symbolic discourse language will provide a formal and (at least within its purview) correct underpinning for the LLM. It may lose the poetry of language that the LLM handles. But from the outset it’ll get its reasoning straight.</p>\n<p>The symbolic discourse language is a broad project. But in some sense breadth is what I have specialized in. Because that’s what’s needed to build out the Wolfram Language, and that’s what’s needed in my efforts to pull together the foundations of so many fields. </p>\n<p>And in maintaining a broad range of interests there are some where I imagine that someday there’ll be a project I can do, but there may for example be many years of “ambient technology” that are needed before that project will be feasible. Usually, though, I have some “conceptual idea” of what the project might be. For example, I’ve followed robotics, imagining that one day there’ll be a way to do “general-purpose robotics”, perhaps constructing everything out of modular elements. I’ve followed biomedicine, partly out of personal self interest, and partly because I think it’ll relate to some of the foundational questions I’m asking in biology. </p>\n<p>But in addition to all the projects where the goal is basic research, or technology development, I’m also hoping to pursue my interests in education. Much of what I hope to do relates to content, but some of it relates to access and motivation. I don’t have perfect evidence, but I strongly believe there’s a lot of young talent out there in the world that never manages to connect for example with things like the educational programs we put on. We–and I—have tried quite hard over the years to “bridge the gap”. But with the world as it is, it’s proved remarkably difficult. But it’s still a problem I’d like to solve, and I’ll keep picking away at it, hoping to change for the better some kids’ “trajectories”. </p>\n<p>But about content I believe my path is clearer. With the modern Wolfram Language I think we’ve gone a long way towards being able to take computational thinking about almost anything, and being able to represent it in a formalized way, and compute from it. But how do people manage to do the computational thinking in the first place? Well, like mathematical thinking and other formalized kinds of thinking, they <a href=\"https://writings.stephenwolfram.com/2016/09/how-to-teach-computational-thinking/\">have to learn how to do it</a>. </p>\n<p>For years people have been telling me I should “write the book” to teach this. And finally in January of this year I started. I’m not sure how long it will take, but I’ll soon be starting to post sections I’ve written so far.</p>\n<p>My goal is to create a general book—and course—that’s an introduction to computational thinking at a level suitable for typical first-year college students. Lots of college students these days say they want to study “computer science”. But really it’s computational X for some field X that they’re ultimately interested in. And neither the theoretical nor the engineering aspects of typical “computer science” are what’s most relevant to them. What they need to know is computational thinking as it might be applied to computational X—not “CS” but what one might call “CX”. </p>\n<p>So what will CX101 be like? In some ways more like a philosophy course than a CS one. Because in the end it’s about generally learning to think, albeit in the new paradigm of computation. And the point is that once someone has a clear computational conceptualization of something, then it’s our job in the Wolfram Language to make sure that <a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/\">it’s easy for them to concretely implement it</a>. </p>\n<p>But how does one teach computational conceptualization? What I’ve concluded is that one needs to anchor it in actual things in the world. Geography. Video. Genomics. Yes, there are principles to explain. But they need practical context to make them useful, or even understandable. And what I’m finding is that framing everything computationally makes things incredibly much easier to explain than before. (A test example coming soon is whether I can easily explain math ideas like algebra and calculus this way.)</p>\n<p>OK, so that’s a lot of projects. But I’m excited about all of them, and can’t wait to make them happen. At an age when many of my contemporaries are retiring, I feel like I’m just getting started. And somehow the way my projects keep on connecting back to things I did decades ago makes me feel—in a computational irreducibility kind of way—that there’s something necessary about all the steps I’ve taken. I feel like the things I’ve done have let me climb some hills. But now there are many more hills that have come into view. And I look forward to being able to climb those too. For myself and for the world.</p>\n",

Some Minimal Models\" title=\"What's Really Going On in Machine Learning? Some Minimal Models\"></p>\n<h2 id=\"the-mystery-of-machine-learning\">The Mystery of Machine Learning</h2>\n<p>It’s surprising how little is known about the foundations of machine learning. Yes, from an engineering point of view, an immense amount has been figured out about how to build neural nets that do all kinds of impressive and <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">sometimes almost magical things</a>. But at a fundamental level we still don’t really know why neural nets “work”—and we don’t have any kind of “scientific big picture” of what’s going on inside them. </p>\n<p>The basic structure of neural networks can be pretty simple. But by the time they’re trained up with all their weights, etc. it’s been hard to tell what’s going on—or even to get any good visualization of it. And indeed it’s far from clear even what aspects of the whole setup are actually essential, and what are just “details” that have perhaps been “grandfathered” all the way from when computational neural nets were first invented in the 1940s.</p>\n<p>Well, what I’m going to try to do here is to get “underneath” this—and to “strip things down” as much as possible. I’m going to explore some very minimal models—that, among other things, are more directly amenable to visualization. At the outset, I wasn’t at all sure that these minimal models would be able to reproduce any of the kinds of things we see in machine learning. But, rather surprisingly, it seems they can.<span id=\"more-61728\"></span></p>\n<p>And the simplicity of their construction makes it much easier to “see inside them”—and to get more of a sense of what essential phenomena actually underlie machine learning. One might have imagined that even though the training of a machine learning system might be circuitous, somehow in the end the system would do what it does through some kind of identifiable and “explainable” mechanism. But we’ll see that in fact that’s typically not at all what happens. </p>\n<p>Instead it looks much more as if the training manages to home in on some quite wild computation that “just happens to achieve the right results”. Machine learning, it seems, isn’t building structured mechanisms; rather, it’s basically just sampling from the typical complexity one sees in the computational universe, picking out pieces whose behavior turns out to overlap what’s needed. And in a sense, therefore, the possibility of machine learning is ultimately yet another consequence of the phenomenon of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>. </p>\n<p>Why is that? Well, it’s only because of computational irreducibility that there’s all that richness in the computational universe. And, more than that, it’s because of computational irreducibility that things end up being effectively random enough that the adaptive process of training a machine learning system can reach success without getting stuck. </p>\n<p>But the presence of computational irreducibility also has another important implication: that even though we can expect to find limited pockets of computational reducibility, we can’t expect a “general narrative explanation” of what a machine learning system does. In other words, there won’t be a traditional (say, mathematical) “general science” of machine learning (or, for that matter, probably also neuroscience). Instead, the story will be much closer to the fundamentally computational “<a href=\"https://www.wolframscience.com/nks/\">new kind of science</a>” that I’ve explored for so long, and that has brought us our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> and <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">the ruliad</a>.</p>\n<p>In many ways, the problem of machine learning is a version of the <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">general problem of adaptive evolution</a>, as encountered <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">for example in biology</a>. In biology we typically imagine that we want to adaptively optimize some overall “fitness” of a system; in machine learning we typically try to adaptively “train” a system to make it align with certain goals or behaviors, most often defined by examples. (And, yes, in practice this is often done by trying to minimize a quantity normally called the “loss”.)</p>\n<p>And while in biology there’s a general sense that “things arise through evolution”, quite how this works has always been rather mysterious. But (rather to my surprise) I recently <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">found a very simple model</a> that seems to do well at capturing at least some of the most essential features of biological evolution. And while the model isn’t the same as what we’ll explore here for machine learning, it has some definite similarities. And in the end we’ll find that the core phenomena of machine learning and of biological evolution appear to be remarkably aligned—and both fundamentally connected to the phenomenon of computational irreducibility.</p>\n<p>Most of what I’ll do here focuses on foundational, theoretical questions. But in understanding more about what’s really going on in machine learning—and what’s essential and what’s not—we’ll also be able to begin to see how in practice machine learning might be done differently, potentially with more efficiency and more generality. </p>\n<h2 id=\"traditional-neural-nets\">Traditional Neural Nets</h2>\n<p><span></p>\n<div id=\"gpt-stripe\" style=\"background: #f6fcff87; padding: 0.75rem 1.5rem;border: 1px solid #aeccd987;font-family: 'Source Sans Pro', sans-serif;margin-bottom: 2.5rem;max-width: 620px;/* font-size: .6rem; */\">\n<p style=\"font-size: .85rem;color: #3f5f6a;line-height: 1.5;padding-bottom: 0;display: block;\"><em>Note: Click any diagram to get Wolfram Language code to reproduce it.</em></p>\n</div>\n<p>To begin the process of understanding the essence of machine learning, let’s start from a very traditional—and familiar—example: a <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#machine-learning-and-the-training-of-neural-nets\">fully connected (“multilayer perceptron”) neural net</a> that’s been trained to compute a certain function <em>f</em>[<em>x</em>]:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08192024traditionalimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08192024traditionalimg1.png' alt='' title='' width='445' height='283'> </div>\n</p></div>\n<p>If one gives a value <em>x</em> as input at the top, then after “rippling through the layers of the network” one gets a value at the bottom that (almost exactly) corresponds to our function <em>f</em>[<em>x</em>]:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08192024traditionalimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08192024traditionalimg2.png' alt='' title='' width='546' height='321'> </div>\n</p></div>\n<p>Scanning through different inputs <em>x</em>, we see different patterns of intermediate values inside the network: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08192024traditionalimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08192024traditionalimg3.png' alt='' title='' width='683' height='281'> </div>\n</p></div>\n<p>And here’s (on a linear and log scale) how each of these intermediate values changes with <em>x</em>.

How are these values that we’re plotting determined? We’re using the <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#neural-nets\">standard setup for a fully connected multilayer network</a>. Each node (“neuron”) on each layer is connected to all nodes on the layer above—and values “flow” down from one layer to the next, being multiplied by the (positive or negative) “weight” (indicated by color in our pictures) associated with the connection through which they flow. The value of a given neuron is found by totaling up all its (weighted) inputs from the layer before, adding a “bias” value for that neuron, and then applying to the result a certain (nonlinear) “<a href=\"https://reference.wolfram.com/language/ref/ElementwiseLayer.html\">activation function</a>” (here ReLU or <tt><a href=\"http://reference.wolfram.com/language/ref/Ramp.html\">Ramp</a></tt>[<em>z</em>], i.e. <tt><a href=\"http://reference.wolfram.com/language/ref/If.html\">If</a></tt>[<em>z</em> < 0, 0, <em>z</em>]).</p>\n<p>What overall function a given neural net will compute is determined by the collection of weights and biases that appear in the neural net (along with its overall connection architecture, and the activation function it’s using). The idea of machine learning is to find weights and biases that produce a particular function by adaptively “learning” from examples of that function.

But to do machine learning, do we really need systems that have all those details? For example, do we really need every neuron on each layer to get an input from every neuron on the previous layer? What happens if instead every neuron just gets input from at most two others—say with the neurons effectively laid out in a simple mesh? Quite surprisingly, it turns out that such a network is still perfectly able to generate a function like the one we’ve been using as an example: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08202024topologyimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08202024topologyimg1.png' alt='' title='' width='403' height='270'> </div>\n</p></div>\n<p>And one advantage of such a “mesh neural net” is that—like a cellular automaton—its “internal behavior” can readily be visualized in a rather direct way.

But, somewhat surprisingly at first, it seems as if we can go much further in simplifying the systems we’re using—and still successfully do versions of machine learning. And in particular we’ll find that we can make our systems completely discrete. </p>\n<p>The typical methodology of neural net training involves progressively tweaking real-valued parameters, usually using methods based on calculus, and on finding derivatives. And one might imagine that any successful adaptive process would ultimately have to rely on being able to make arbitrarily small changes, of the kind that are possible with real-valued parameters. </p>\n<p>But in <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">studying simple idealizations of biological evolution</a> I recently found striking examples where this isn’t the case—and where completely discrete systems seemed able to capture the essence of what’s going on. </p>\n<p>As an example consider a (3-color) cellular automaton.

And the important point is that this rule can be found by a discrete adaptive process. The idea is to start, say, from a null rule, and then at each step to randomly change a single outcome out of the 27 in the rule (i.e. make a “single-point mutation” in the rule). Most such changes will cause the “lifetime” of the pattern to get further from our target of 40—and these we discard.

First, that they essentially all seem to be “using different ideas” to reach their goal (presumably analogous to the phenomenon of different branches in the tree of life). And second, that none of them seem to be using a clear “mechanical procedure” (of the kind we might construct through traditional engineering) to reach their goal. Instead, they seem to be finding “natural” complicated behavior that just “happens” to achieve the goal.</p>\n<p>It’s nontrivial, of course, that this behavior can achieve a goal like the one we’ve set here, as well as that simple selection based on random point mutations can successfully reach the necessary behavior. But <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">as I discussed in connection with biological evolution</a>, this is ultimately a story of <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>—particularly in generating diversity both in behavior, and in the paths necessary to reach it. </p>\n<p>But, OK, so how does this model of adaptive evolution relate to systems like neural nets? In the standard language of neural nets, our model is like a discrete analog of a recurrent convolutional network. It’s “convolutional” because at any given step the same rule is applied—locally—throughout an array of elements. It’s “recurrent” because in effect data is repeatedly “passed through” the same rule. The kinds of procedures (like “backpropagation”) typically used to train traditional neural nets wouldn’t be able to train such a system. But it turns out that—essentially as a consequence of computational irreducibility—the very simple method of successive random mutation can be successful.</p>\n<h2 id=\"machine-learning-in-discrete-rule-arrays\">Machine Learning in Discrete Rule Arrays</h2>\n<p>Let’s say we want to set up a system like a neural net—or at least a mesh neural net—but we want it to be completely discrete. (And I mean “born discrete”, not just discretized from an existing continuous system.) How can we do this? One approach (that, as it happens, <a href=\"https://content.wolfram.com/sw-publications/2020/07/approaches-complexity-engineering.pdf\">I first considered in the mid-1980s</a>—but never seriously explored) is to make what we can call a “rule array”. Like in a cellular automaton there’s an array of cells. But instead of these cells always being updated according to the same rule, each cell at each place in the cellular automaton analog of “spacetime” can make a different choice of what rule it will use. (And although it’s a fairly extreme idealization, we can potentially imagine that these different rules represent a discrete analog of different local choices of weights in a mesh neural net.)</p>\n<p>As a first example, let’s consider a rule array in which there are two possible choices of rules: <nobr><em>k </em>= 2, <em>r </em>= 1</nobr> <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs#sect-3-2--more-cellular-automata\">cellular automaton rules 4 and 146</a> (which are respectively <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-2--four-classes-of-behavior\">class 2 and class 3</a>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08192024arraysimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08192024arraysimg1.png' alt='' title='' width='366' height='116'> </div>\n</p></div>\n<p>A particular rule array is defined by which of these rules is going to be used at each (“spacetime”) position in the array.

Well, first we have to decide how we’re going to represent the numbers <em>x</em> and <em>f</em>[<em>x</em>] in our discrete rule array system. And one approach is to do this simply in terms of the position of a black cell (“one-hot encoding”). So, for example, in this case there’s an initial black cell at a position corresponding to about <em>x</em> = –1.1. And then the result after passing through the rule array is a black cell at a position corresponding to <em>f</em>[<em>x</em>] = 1.0:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysCimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysCimg1.png' alt='' title='' width='188' height='304'> </div>\n</p></div>\n<p>So now the question is whether we can find a rule array that successfully maps initial to final cell positions according to the mapping <em>x</em> <img style=\"margin-bottom: -2px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow.png\" width='18' height='12'> <em>f</em>[<em>x</em>] we want. Well, here’s an example that comes at least close to doing this (note that the array is taken to be cyclic):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg24_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg24.png' alt='' title='' width='687' height='414'> </div>\n</p></div>\n<p>So how did we find this? Well, we just used a simple adaptive evolution process. In direct analogy to the way it’s usually done in machine learning, we set up “training examples”, here of the form:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08222024MLupdatesAimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08222024MLupdatesAimg3.png' alt='' title='' width='573' height='76'> </div>\n</p></div>\n<p>Then we repeatedly made single-point mutations in our rule array, keeping those mutations where the total difference from all the training examples didn’t increase. And after 50,000 mutations this gave the final result above. </p>\n<p>We can get some sense of “how we got there” by showing the sequence of intermediate results where we got closer to the goal (as opposed to just not getting further from it):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg26_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg26.png' alt='' title='' width='597' height='246'> </div>\n</p></div>\n<p>Here are the corresponding rule arrays, in each case highlighting elements that have changed (and showing the computation of <em>f</em>[0] in the arrays):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg27_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg27.png' alt='' title='' width='609' height='289'> </div>\n</p></div>\n<p>Different sequences of random mutations will lead to different rule arrays. But with the setup defined here, the resulting rule arrays will almost always succeed in accurately computing <em>f</em>[<em>x</em>]. Here are a few examples—in which we’re specifically showing the computation of <em>f</em>[0]:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg28_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg28.png' alt='' title='' width='642' height='109'> </div>\n</p></div>\n<p>And once again an important takeaway is that we don’t see “identifiable mechanism” in what’s going on. Instead, it looks more as if the rule arrays we’ve got just “happen” to do the computations we want. Their behavior is complicated, but somehow we can manage to “tap into it” to compute our <em>f</em>[<em>x</em>].</p>\n<p>But how robust is this computation? A key feature of typical machine learning is that it can “generalize” away from the specific examples it’s been given. It’s never been clear just how to characterize that generalization (when does an image of a cat in a dog suit start <a href=\"https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/\">being identified as an image of a dog</a>?). But—at least when we’re talking about classification tasks—we can think of what’s going on in terms of <a href=\"https://www.wolframscience.com/nks/p624--human-thinking/\">basins of attraction</a> that lead to attractors corresponding to our classes.</p>\n<p>It’s all considerably easier to analyze, though, in the kind of discrete system we’re exploring here. For example, we can readily enumerate all our training inputs (i.e. all initial states containing a single black cell), and then see how frequently these cause any given cell to be black:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08242024arraysupdateFimg1_copy.txt' data-c2c-type='text/html'> <img src='https://content.wolfram.com/sites/43/2024/08/sw08242024arraysupdateFimg2.png' alt='' title='' width='186' height='302'/> </div>\n</p></div>\n<p>By the way, here’s what happens to this plot at successive “breakthroughs” during training:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg30_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg30.png' alt='' title='' width='660' height='309'> </div>\n</p></div>\n<p>But what about all possible inputs, including ones that don’t just contain a single black cell? Well, we can enumerate all of them, and compute the overall frequency for each cell in the array to be black:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08222024MLupdatesAimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08222024MLupdatesAimg4.png' alt='' title='' width='188' height='304'> </div>\n</p></div>\n<p>As we would expect, the result is considerably “fuzzier” than what we got purely with our training inputs. But there’s still a strong trace of the discrete values for <em>f</em>[<em>x</em>] that appeared in the training data. And if we plot the overall probability for a given final cell to be black, we see peaks at positions corresponding to the values 0 and 1 that <em>f</em>[<em>x</em>] takes on:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg32_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg32.png' alt='' title='' width='276' height='76'> </div>\n</p></div>\n<p>But because our system is discrete, we can explicitly look at what outcomes occur: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg33_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024arraysBimg33.png' alt='' title='' width='348' height='193'> </div>\n</p></div>\n<p>The most common overall is the “meaningless” all-white state—that basically occurs when the computation from the input “never makes it” to the output. But the next most common outcomes correspond exactly to <em>f</em>[<em>x</em>] = 0 and <em>f</em>[<em>x</em>] = 1. After that is the “superposition” outcome where <em>f</em>[<em>x</em>] is in effect “both 0 and 1”. </p>\n<p>But, OK, so what initial states are “in the basins of attraction of” (i.e. will evolve to) the various outcomes here? The fairly flat plots in the last column above indicate that the overall density of black cells gives little information about what attractor a particular initial state will evolve to. </p>\n<p>So this means we have to look at specific configurations of cells in the initial conditions.

But now we have a sense of what the reason for this is: it’s another consequence of computational irreducibility. Computational irreducibility gives us the effective randomness that allows us to find useful results by adaptive evolution, but it also leads to changes having what seem like random and unpredictable effects. (It’s worth noting, by the way, that we could probably dramatically improve the robustness of our attractor basins by specifically including in our training data examples that have “noise” injected.)</p>\n<h2 id=\"multiway-mutation-graphs\">Multiway Mutation Graphs</h2>\n<p>In doing machine learning in practice, the goal is typically to find some collection of weights, etc. that successfully solve a particular problem.

In practical work with traditional neural nets, learning is normally done using systematic algorithmic methods like backpropagation. But so far, all we’ve done here is something much simpler: we’ve “learned” by successively making random point mutations, and keeping only ones that don’t lead us further from our goal. And, yes, it’s interesting that such a procedure can work at all—and (<a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">as we’ve discussed elsewhere</a>) this is presumably very relevant to understanding phenomena like biological evolution. But, as we’ll see, there are more efficient (and probably much more efficient) methods of doing machine learning, even for the kinds of discrete systems we’re studying.</p>\n<p>Let’s start by looking again at our earlier example of finding an <tt>And</tt>+<tt>Xor</tt> rule array that gives a “lifetime” of exactly 30. At each step in our adaptive (“learning”) process we make a single-point mutation (changing a single rule in the rule array), keeping the mutation if it doesn’t take us further from our goal. The mutations gradually accumulate—every so often reaching a rule array that gives a lifetime closer to 30. Just as above, here’s a plot of the lifetime achieved by successive mutations—with the “internal” red dots corresponding to rejected mutations:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg1.png' alt='' title='' width='349' height='123'> </div>\n</p></div>\n<p>We see a series of “plateaus” at which mutations are accumulating but not changing the overall lifetime. And between these we see occasional “breakthroughs” where the lifetime jumps. Here are the actual rule array configurations for these breakthroughs, with mutations since the last breakthrough highlighted:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg2.png' alt='' title='' width='592' height='397'> </div>\n</p></div>\n<p>But in the end the process here is quite wasteful; in this example, we make a total of 1705 mutations, but only 780 of them actually contribute to generating the final rule array; all the others are discarded along the way.</p>\n<p>So how can we do better? One strategy is to try to figure out at each step which mutation is “most likely to make a difference”. And one way to do this is to try every possible mutation in turn at every step (as in multiway evolution)—and see what effect each of them has on the ultimate lifetime. From this we can construct a “change map” in which we give the change of lifetime associated with a mutation at every particular cell. The results will be different for every configuration of rule array, i.e. at every step in the adaptive evolution. But for example here’s what they are for the particular “breakthrough” configurations shown above (elements in regions that are colored gray won’t affect the result if they are changed; ones colored red will have a positive effect (with more intense red being more positive), and ones colored blue a negative one:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg3.png' alt='' title='' width='542' height='335'> </div>\n</p></div>\n<p>Let’s say we start from a random rule array, then repeatedly construct the change map and apply the mutation that it implies gives the most positive change—in effect at each step following the “path of steepest descent” to get to the lifetime we want (i.e. reduce the loss). Then the sequence of “breakthrough” configurations we get is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08222024otimizingUPDATEimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg4.png' alt='' title='' width='536' height='171'> </div>\n</p></div>\n<p>And this in effect corresponds to a slightly more direct “path to a solution” than our sequence of pure single-point mutations. </p>\n<p>By the way, the particular problem of reaching a certain lifetime has a simple enough structure that this “steepest descent” method—when started from a simple uniform rule array—finds a very “mechanical” (if slow) path to a solution:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg5.png' alt='' title='' width='640' height='124'> </div>\n</p></div>\n<p>What about the problem of learning <em>f</em>[<em>x</em>] = <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg6.png' alt='' title='' width='51' height='13'/>? Once again we can make a change map based on the loss we define. Here are the results for a sequence of “breakthrough” configurations. The gray regions are ones where changes will be “neutral”, so that there’s still exploration that can be done without affecting the loss. The red regions are ones that are in effect “locked in” and where any changes would be deleterious in terms of loss:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg7.png' alt='' title='' width='644' height='224'> </div>\n</p></div>\n<p>So what happens in this case if we follow the “path of steepest descent”, always making the change that would be best according to the change map? Well, the results are actually quite unsatisfactory. From almost any initial condition the system quickly gets stuck, and never finds any satisfactory solution. In effect it seems that deterministically following the path of steepest descent leads us to a “local minimum” from which we cannot escape. So what are we missing in just looking at the change map? Well, the change map as we’ve constructed it has the limitation that it’s separately assessing the effect of each possible individual mutation. It doesn’t deal with multiple mutations at a time—which could well be needed in general if one’s going to find the “fastest path to success”, and avoid getting stuck.</p>\n<p>But even in constructing the change map there’s already a problem. Because at least the direct way of computing it scales quite poorly. In an <em>n</em>×<em>n</em> rule array we have to check the effect of flipping about <em>n</em><sup>2</sup> values, and for each one we have to run the whole system—taking altogether about <em>n</em><sup>4</sup> operations. And one has to do this separately for each step in the learning process.</p>\n<p>So how do traditional neural nets avoid this kind of inefficiency? The answer in a sense involves a mathematical trick. And at least as it’s usually presented it’s all based on the continuous nature of the weights and values in neural nets—which allow us to use methods from calculus. </p>\n<p>Let’s say we have a neural net like this</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg10.png' alt='' title='' width='94' height='173'> </div>\n</p></div>\n<p>that computes some particular function <em>f</em>[<em>x</em>]:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg11.png' alt='' title='' width='148' height='95'> </div>\n</p></div>\n<p>We can ask how this function changes as we change each of the weights in the network:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg12.png' alt='' title='' width='625' height='231'> </div>\n</p></div>\n<p>And in effect this gives us something like our “change map” above. But there’s an important difference. Because the weights are continuous, we can think about infinitesimal changes to them. And then we can ask questions like “How does <em>f</em>[<em>x</em>] change when we make an infinitesimal change to a particular weight <em>w</em><sub><em>i</em></sub>?”—or equivalently, “What is the partial derivative of <em>f</em> with respect to <em>w</em><sub><em>i</em></sub> at the point <em>x</em>?” But now we get to use a key feature of infinitesimal changes: that they can always be thought of as just “adding linearly” (essentially because ε<sup>2</sup> can always be ignored compared to ε). Or, in other words, we can summarize any infinitesimal change just by giving its “direction” in weight space, i.e. a vector that says how much of each weight should be (infinitesimally) changed. So if we want to change <em>f</em>[<em>x</em>] (infinitesimally) as quickly as possible, we should go in the direction of steepest descent defined by all the derivatives of <em>f</em> with respect to the weights.</p>\n<p>In machine learning, we’re typically trying in effect to set the weights so that the form of <em>f</em>[<em>x</em>] we generate successfully minimizes whatever loss we’ve defined. And we do this by incrementally “moving in weight space”—at every step computing the direction of steepest descent to know where to go next. (In practice, there are all sorts of tricks like “ADAM” that try to optimize the way to do this.)</p>\n<p>But how do we efficiently compute the partial derivative of <em>f</em> with respect to each of the weights? Yes, we could do the analog of generating pictures like the ones above, separately for each of the weights. But it turns out that a standard result from calculus gives us a vastly more efficient procedure that in effect “maximally reuses” parts of the computation that have already been done. </p>\n<p>It all starts with the textbook chain rule for the derivative of nested (i.e. composed) functions:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg16.png' alt='' title='' width='145' height='44'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg17_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg17.png' alt='' title='' width='239' height='44'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg18_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg18.png' alt='' title='' width='361' height='44'> </div>\n</p></div>\n<p>This basically says that the (infinitesimal) change in the value of the “whole chain” <em>d</em>[<em>c</em>[<em>b</em>[<em>a</em>[<em>x</em>]]]] can be computed as a product of (infinitesimal) changes associated with each of the “links” in the chain. But the key observation is then that when we get to the computation of the change at a certain point in the chain, we’ve already had to do a lot of the computation we need—and so long as we stored those results, we always have only an incremental computation to perform.</p>\n<p>So how does this apply to neural nets?

But actually such reversibility doesn’t seem to help much—because although it allows us to “backtrack” whole states of the cellular automaton, it doesn’t allow us to trace the separate effects of individual cells. </p>\n<p>So how about using discrete analogs of derivatives and the chain rule? Let’s for example call the function computed by one step in rule 30 cellular automaton evolution <em>w</em>[<em>x</em>, <em>y</em>, <em>z</em>].

In our simple cellular automaton case, we can think of our change map as representing how a <a href=\"https://www.wolframscience.com/nks/p604--cryptography-and-cryptanalysis/\">change in an output cell “propagates back”</a> to previous cells. But if we just try to apply our discrete calculus rules we run into a problem: different “chain rule chains” can imply different changes in the value of the same cell. In the continuous case this path dependence doesn’t happen because of the way infinitesimals work. But in the discrete case it does. And ultimately we’re doing a kind of backtracking that can really be represented faithfully only as a multiway system. (Though if we just want probabilities, for example, we can consider <a href=\"https://www.wolframphysics.org/bulletins/2021/02/multiway-turing-machines/\" target=\"_blank\" rel=\"noopener\">averaging over branches of the multiway system</a>—and the change maps we showed above are effectively the result of thresholding over the multiway system.)</p>\n<p>But despite the appearance of such difficulties in the “simple” cellular automaton case, such methods typically seem to work better in our original, more complicated rule array case. There’s a bunch of subtlety associated with the fact that we’re finding derivatives not only with respect to the values in the rule array, but also with respect to the choice of rules (which are the analog of weights in the continuous case). </p>\n<p>Let’s consider the <tt>And</tt>+<tt>Xor</tt> rule array:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg44_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg44.png' alt='' title='' width='171' height='162'> </div>\n</p></div>\n<p>Our loss is the number of cells whose values disagree with the row shown at the bottom. Now we can construct a change map for this rule array both in a direct “forward” way, and “backwards” using our discrete derivative methods (where we effectively resolve the small amount of “multiway behavior” by always picking “majority” values): </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg45_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024optimizingimg45.png' alt='' title='' width='293' height='149'> </div>\n</p></div>\n<p>The results are similar, though in this case not exactly the same.

What functions can they represent? We already saw part of the answer earlier when we generated rule arrays to represent various Boolean functions. It turns out that there is a fairly efficient procedure based on <a href=\"https://reference.wolfram.com/language/ref/SatisfiabilityInstances.html\">Boolean satisfiability</a> for explicitly finding rule arrays that can represent a given function—or determine that no rule array (say of a given size) can do this. </p>\n<p>Using this procedure, we can find minimal <tt>And</tt>+<tt>Xor</tt> rule arrays that represent all (“even”) 3-input Boolean functions (i.e. <em>r</em> = 1 cellular automaton rules):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg8.png' alt='' title='' width='641' height='462'> </div>\n</p></div>\n<p>It’s always possible to specify any <em>n</em>-input Boolean function by an array of 2<sup><em>n</em></sup> bits, as in:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg10.png' alt='' title='' width='206' height='22'> </div>\n</p></div>\n<p>But we see from the pictures above that when we “compile” Boolean functions into <tt>And</tt>+<tt>Xor</tt> rule arrays, they can take different numbers of bits (i.e. different numbers of elements in the rule array). (In effect, the “algorithmic information content” of the function varies with the “language” we’re using to represent them.) And, for example, in the <em>n </em>= 3 case shown here, the distribution of minimal rule array sizes is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg11.png' alt='' title='' width='216' height='114'> </div>\n</p></div>\n<p>There are some functions that are difficult to represent as <tt>And</tt>+<tt>Xor</tt> rule arrays (and seem to require 15 rule elements)—and others that are easier.

But now we’ve got a case where we can explicitly enumerate all possible functions, at least of a given class. And in a sense what we’re seeing is evidence that machine learning tends to be very broad—and capable at least in principle of learning pretty much any function. </p>\n<p>Of course, there can be specific restrictions. Like the <tt>And</tt>+<tt>Xor</tt> rule arrays we’re using here can’t represent (“odd”) functions where <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg16.png' alt='' title='' width='69' height='9'/>. (The <tt><a href=\"https://reference.wolfram.com/language/ref/Nand.html\">Nand</a></tt>+<tt><a href=\"https://reference.wolfram.com/language/ref/First.html\">First</a></tt> rule arrays we discussed above nevertheless can.) But in general it seems to be a reflection of the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> that pretty much any setup is capable of representing any function—and also adaptively “learning” it. </p>\n<p>By the way, it’s a lot easier to discuss questions about representing or learning “any function” when one’s dealing with discrete (countable) functions—because one can expect to either be able to “exactly get” a given function, or not. But for continuous functions, it’s more complicated, because one’s pretty much inevitably dealing with approximations (unless one can use symbolic forms, which are basically discrete). So, for example, while we can say (as we did above) that (ReLU) neural nets can represent any piecewise-linear function, in general we’ll only be able to imagine successively approaching an arbitrary function, much like when you progressively add more terms in a simple Fourier series:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg17_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024learnedimg17.png' alt='' title='' width='639' height='74'> </div>\n</p></div>\n<p>Looking back at our results for discrete rule arrays, one notable observation that is that while we can successfully reproduce all these different Boolean functions, the actual rule array configurations that achieve this tend to look quite messy.

But in getting a sense of what rule arrays can do, we can consider rule arrays that are “<a href=\"https://www.wolframscience.com/nks/chap-11--the-notion-of-computation/\">programmable</a>”, in that their input specifies what function they should compute.

Mostly we’ve concentrated on rule arrays as a way to provide a minimal analog of standard “perceptron-style” feed-forward neural nets. But what about other architectures and setups?</p>\n<p>In effect, our rule arrays are “spacetime-inhomogeneous” generalizations of cellular automata—in which adaptive evolution determines which rule (say from a finite set) should be used at every (spatial) position and every (time) step. A different idealization (that in fact we already used in <a href=\"https://writings.stephenwolfram.com/2024/08/whats-really-going-on-in-machine-learning-some-minimal-models/#making-everything-discrete-a-biological-evolution-analog\">one section above</a>) is to have an ordinary homogeneous cellular automaton—but with a single “global rule” determined by adaptive evolution. Rule arrays are the analog of feed-forward networks in which a given rule in the rule array is in effect used only once as data “flows through” the system. Ordinary homogeneous cellular automata are like recurrent networks in which a single stream of data is in effect subjected over and over again to the same rule.</p>\n<p>There are various interpolations between these cases. For example, we can imagine a “layered rule array” in which the rules at different steps can be different, but those on a given step are all the same. Such a system can be viewed as an idealization of a convolutional neural net in which a given layer applies the same kernel to elements at all positions, but different layers can apply different kernels.</p>\n<p>A layered rule array can’t encode as much information as a general rule array. But it’s still able to show machine-learning-style phenomena. And here, for example, is adaptive evolution for a layered <tt>And</tt>+<tt>Xor</tt> rule array progressively solving the problem of generating a pattern that lives for exactly 30 steps:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg1.png' alt='' title='' width='591' height='329'> </div>\n</p></div>\n<p>One could also imagine “vertically layered” rule arrays, in which different rules are used at different positions, but any given position keeps running the same rule forever. However, at least for the kinds of problems we’ve considered here, it doesn’t seem sufficient to just be able to pick the positions at which different rules are run. One seems to either need to change rules at different (time) steps, or one needs to be able to adaptively evolve the underlying rules themselves.</p>\n<p>Rule arrays and ordinary cellular automata share the feature that the value of each cell depends only on the values of neighboring cells on the step before. But in neural nets it’s standard for the value at a given node to depend on the values of lots of nodes on the layer before. And what makes this straightforward in neural nets is that (weighted, and perhaps otherwise transformed) values from previous nodes are taken to be combined just by simple numerical addition—and addition (being <em>n</em>-ary and associative) can take any number of “inputs”. In a cellular automaton (or Boolean function), however, there’s always a definite number of inputs, determined by the structure of the function. In the most straightforward case, the inputs come only from nearest-neighboring cells. But there’s no requirement that this is how things need to work—and for example we can pick any “local template” to bring in the inputs for our function. This template could either be the same at every position and every step, or it could be picked from a certain set differently at different positions—in effect giving us “template arrays” as well as rule arrays.</p>\n<p>So what about having a fully connected network, as we did in our very first neural net examples above? To set up a discrete analog of this we first need some kind of discrete <em>n</em>-ary associative “accumulator” function to fill the place of numerical addition. And for this <a href=\"https://www.wolframscience.com/nks/notes-12-9--properties-of-logical-primitives/\">we could pick a function like</a> <tt><a href=\"http://reference.wolfram.com/language/ref/And.html\">And</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/Or.html\">Or</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/Xor.html\">Xor</a></tt>—or <tt><a href=\"http://reference.wolfram.com/language/ref/Majority.html\">Majority</a></tt>. And if we’re not just going to end up with the same value at each node on a given layer, we need to set up some analog of a weight associated with each connection—which we can achieve by applying either <tt><a href=\"http://reference.wolfram.com/language/ref/Identity.html\">Identity</a></tt> or <tt><a href=\"http://reference.wolfram.com/language/ref/Not.html\">Not</a></tt> (i.e. flip or not) to the value flowing through each connection. </p>\n<p>Here’s an example of a network of this type, trained to compute the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg2.png' alt='' title='' width='51' height='13'/> function we discussed above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg3.png' alt='' title='' width='591' height='138'> </div>\n</p></div>\n<p>There are just two kinds of connections here: flip and not. And at each node we’re computing the majority function—giving value 1 if the majority of its inputs are 1, and 0 otherwise. With the “one-hot encoding” of input and output that we used before, here are a few examples of how this network evaluates our function:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg4.png' alt='' title='' width='613' height='126'> </div>\n</p></div>\n<p>This was trained just using 1000 steps of single-point mutation applied to the connection types.

But we can also consider a network where connections can end up being zeroed out during training—so that they are effectively no longer present. </p>\n<p>Much of what we’ve done here with machine learning has centered around trying to learn transformations of the form <em>x </em><img style=\"margin-bottom: -1px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow2.png\" width='15' height='11' > <em>f</em>[<em>x</em>]. But another typical application of machine learning is autoencoding—or in effect learning how to compress data representing a certain set of examples. And once again it’s possible to do such a task using rule arrays, with learning achieved by a series of single-point mutations. </p>\n<p>As a starting point, consider training a rule array (of cellular automaton rules 4 and 146) to reproduce unchanged a block of black cells of any width. One might have thought this would be trivial. But it’s not, because in effect the initial data inevitably gets “ground up” inside the rule array, and has to be reconstituted at the end. But, yes, it’s nevertheless possible to train a rule array to at least roughly do this—even though once again the rule arrays we find that manage to do this look quite random:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg6.png' alt='' title='' width='668' height='261'> </div>\n</p></div>\n<p>But to set up a nontrivial autoencoder let’s imagine that we progressively “squeeze” the array in the middle, creating an increasingly narrow “bottleneck” through which the data has to flow. At the bottleneck we effectively have a compressed version of the original data. And we find that at least down to some width of bottleneck, it’s possible to create rule arrays that—with reasonable probability—can act as successful autoencoders of the original data:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08212024modelsimg7B.png' alt='' title='' width='679' height='700'> </div>\n</p></div>\n<p>The success of LLMs has highlighted the use of machine learning for sequence continuation—and the effectiveness of transformers for this.

But if we were to simplify it further, we would end up not with something like a cellular automaton but instead with something like a <a href=\"https://www.wolframscience.com/nks/p93--tag-systems/\">tag system</a>, in which one has a sequence of elements, and at each step removes a block from the beginning, and<tt>—</tt>depending on its form<tt>—</tt>adds a certain block at the end, as in:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/08/sw08222024modelsAimg22_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08222024modelsAimg22.png' alt='' title='' width='632' height='402'> </div>\n</p></div>\n<p>And, yes, such systems <a href=\"https://writings.stephenwolfram.com/2021/03/after-100-years-can-we-finally-crack-posts-problem-of-tag-a-story-of-computational-irreducibility-and-more/\">can generate extremely complex behavior</a><tt>—</tt>reinforcing the idea (that we have repeatedly seen here) that machine learning works by selecting complexity that aligns with goals that have been set.</p>\n<p>And along these lines, one can consider all sorts of different computational systems as foundations for machine learning. Here we’ve been looking at cellular-automaton-like and tag-system-like examples. But for example our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> has shown us the power and flexibility of systems based on <a href=\"https://www.wolframphysics.org/technical-introduction/basic-form-of-models/\" target=\"_blank\" rel=\"noopener\">hypergraph rewriting</a>. And from what we’ve seen here, it seems very plausible that something like hypergraph rewriting can serve as a yet more powerful and flexible substrate for machine learning.</p>\n<h2 id=\"so-in-the-end-whats-really-going-on-in-machine-learning\">So in the End, What’s Really Going On in Machine Learning?</h2>\n<p>There are, I think, several quite striking conclusions from what we’ve been able to do here. The first is just that models much simpler than traditional neural nets seem capable of capturing the essential features of machine learning—and indeed these models may well be the basis for a new generation of practical machine learning.</p>\n<p>But from a scientific point of view, one of the things that’s important about these models is that they are simple enough in structure that it’s immediately possible to produce visualizations of what they’re doing inside. And studying these visualizations, the most immediately striking feature is how complicated they look. </p>\n<p>It could have been that machine learning would somehow “crack systems”, and find simple representations for what they do. But that doesn’t seem to be what’s going on at all. Instead what seems to be happening is that machine learning is in a sense just “hitching a ride” on the <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs/\">general richness of the computational universe</a>. It’s not “specifically building up behavior one needs”; rather what it’s doing is to harness behavior that’s “already out there” in the computational universe.</p>\n<p>The fact that this could possibly work relies on the crucial—and at first unexpected—fact that in the computational universe even very simple programs can ubiquitously produce all sorts of complex behavior. And the point then is that this behavior has enough richness and diversity that it’s possible to find instances of it that align with machine learning objectives one’s defined. In some sense what machine learning is doing is to “mine” the computational universe for programs that do what one wants. </p>\n<p>It’s not that machine learning nails a specific precise program. Rather, it’s that in typical successful applications of machine learning there are lots of programs that “do more or less the right thing”. If what one’s trying to do involves something computationally irreducible, machine learning won’t typically be able to “get well enough aligned” to correctly “get through all the steps” of the irreducible computation. But it seems that <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#models-for-human-like-tasks\">many “human-like tasks”</a> that are the particular focus of modern machine learning can successfully be done. </p>\n<p>And by the way, one can expect that with the minimal models explored here, it becomes more feasible to get a real characterization of what kinds of objectives can successfully be achieved by machine learning, and what cannot. Critical to the operation of machine learning is not only that there exist programs that can do particular kinds of things, but also that they can realistically be found by adaptive evolution processes.</p>\n<p>In what we’ve done here we’ve often used what’s essentially the very simplest possible process for adaptive evolution: a sequence of point mutations. And what we’ve discovered is that even this is usually sufficient to lead us to satisfactory machine learning solutions. It could be that our paths of adaptive evolution would always be getting stuck—and not reaching any solution. But the fact that this doesn’t happen seems <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/#the-fitness-landscape\">crucially connected to the computational irreducibility</a> that’s ubiquitous in the systems we’re studying, and that leads to effective randomness that with overwhelming probability will “give us a way out” of anywhere we got stuck.</p>\n<p>In some sense computational irreducibility “levels the playing field” for different processes of adaptive evolution, and lets even simple ones be successful. Something similar seems to happen for the whole framework we’re using. Any of a wide class of systems seem capable of successful machine learning, even if they don’t have the detailed structure of traditional neural nets. We can see this as a typical reflection of the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a>: that even though systems may differ in their details, they are ultimately all equivalent in the computations they can do.</p>\n<p>The phenomenon of computational irreducibility leads to a fundamental tradeoff, of <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/\">particular importance in thinking about things like AI</a>. If we want to be able to know in advance—and broadly guarantee—what a system is going to do or be able to do, we have to set the system up to be computationally reducible. But if we want the system to be able to make the richest use of computation, it’ll inevitably be capable of computationally irreducible behavior. And it’s the same story with machine learning. If we want machine learning to be able to do the best it can, and perhaps give us the impression of “achieving magic”, then we have to allow it to show computational irreducibility. And if we want machine learning to be “understandable” it has to be computationally reducible, and not able to access the full power of computation.</p>\n<p>At the outset, though, it’s not obvious whether machine learning actually has to access such power. It could be that there are computationally reducible ways to solve the kinds of problems we want to use machine learning to solve. But what we’ve discovered here is that even in solving very simple problems, the adaptive evolution process that’s at the heart of machine learning will end up sampling—and using—what we can expect to be computationally irreducible processes. </p>\n<p>Like biological evolution, machine learning is fundamentally about finding things that work—without the constraint of “understandability” that’s forced on us when we as humans explicitly engineer things step by step. Could one imagine constraining machine learning to make things understandable? To do so would effectively prevent machine learning from having access to the power of computationally irreducible processes, and from the evidence here it seems unlikely that with this constraint the kind of successes we’ve seen in machine learning would be possible.</p>\n<p>So what does this mean for the “science of machine learning”? One might have hoped that one would be able to “look inside” machine learning systems and get detailed narrative explanations for what’s going on; that in effect one would be able to “explain the mechanism” for everything. But what we’ve seen here suggests that in general nothing like this will work. All one will be able to say is that somewhere out there in the computational universe there’s some (typically computationally irreducible) process that “happens” to be aligned with what we want. </p>\n<p>Yes, we can make general statements—strongly based on computational irreducibility—about things like the findability of such processes, say by adaptive evolution. But if we ask “How in detail does the system work?”, there won’t be much of an answer to that. Of course we can trace all its computational steps and see that it behaves in a certain way. But we can’t expect what amounts to a “global human-level explanation” of what it’s doing. Rather, we’ll basically just be reduced to looking at some computationally irreducible process and observing that it “happens to work”—and we won’t have a high-level explanation of “why”.</p>\n<p>But there is one important loophole to all this. Within any computationally irreducible system, there are always inevitably pockets of computational reducibility. And—as I’ve <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/\">discussed at length particularly in connection with our Physics Project</a>—it’s these pockets of computational reducibility that allow computationally bounded observers like us to identify things like “laws of nature” from which we can build “human-level narratives”.</p>\n<p>So what about machine learning? What pockets of computational reducibility show up there, from which we might build “human-level scientific laws”? Much as with the emergence of “simple continuum behavior” from computationally irreducible processes happening at the level of molecules in a gas or ultimate discrete elements of space, we can expect that at least certain computationally reducible features will be more obvious when one’s dealing with larger numbers of components. And indeed in sufficiently large machine learning systems, it’s routine to see smooth curves and apparent regularity when one’s looking at the kind of aggregated behavior that’s probed by things like training curves.</p>\n<p>But the question about pockets of reducibility is always whether they end up being aligned with things we consider interesting or useful. Yes, it could be that machine learning systems would exhibit some kind of collective (“EEG-like”) behavior. But what’s not clear is whether this behavior will tell us anything about the actual “information processing” (or whatever) that’s going on in the system. And if there is to be a “science of machine learning” what we have to hope for is that we can find in machine learning systems pockets of computational reducibility that are aligned with things we can measure, and care about.</p>\n<p>So given what we’ve been able to explore here about the foundations of machine learning, what can we say about the <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/\">ultimate power of machine learning systems</a>? A key observation has been that machine learning works by “piggybacking” on computational irreducibility—and in effect by finding “natural pieces of computational irreducibility” that happen to fit with the objectives one has. But what if those objectives involve computational irreducibility—as they often do when one’s dealing with a process that’s been successfully formalized in computational terms (as in math, exact science, computational X, etc.)? Well, it’s not enough that our machine learning system “uses some piece of computational irreducibility inside”. To achieve a particular computationally irreducible objective, the system would have to do something closely aligned with that actual, specific objective. </p>\n<p>It has to be said, however, that by laying bare more of the essence of machine learning here, it becomes easier to at least define the issues of merging typical “formal computation” with machine learning. Traditionally there’s been a tradeoff between the computational power of a system and its trainability. And indeed in terms of what we’ve seen here this seems to reflect the sense that “larger chunks of computational irreducibility” are more difficult to fit into something one’s incrementally building up by a process of adaptive evolution.</p>\n<p>So how should we ultimately think of machine learning? In effect its power comes from leveraging the “natural resource” of computational irreducibility. But when it uses computational irreducibility it does so by “foraging” pieces that happen to advance its objectives. Imagine one’s building a wall. One possibility is to fashion bricks of a particular shape that one knows will fit together. But another is just to look at stones one sees lying around, then to build the wall by fitting these together as best one can. </p>\n<p>And if one then asks “Why does the wall have such-and-such a pattern?” the answer will end up being basically “Because that’s what one gets from the stones that happened to be lying around”. There’s no overarching theory to it in itself; it’s just a reflection of the resources that were out there. Or, in the case of machine learning, one can expect that what one sees will be to a large extent a reflection of the raw characteristics of computational irreducibility. In other words, the foundations of machine learning are as much as anything rooted in the <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#the-pure-basic-science-of-ruliology\">science of ruliology</a>. And it’s in large measure to that science we should look in our efforts to understand more about “what’s really going on” in machine learning, and quite possibly also in neuroscience.</p>\n<h2 id=\"historical--personal-notes\" style='font-size:1.2rem'>Historical & Personal Notes</h2>\n<p style='font-size:90%'>In some ways it seems like a quirk of intellectual history that the kinds of foundational questions I’ve been discussing here weren’t already addressed long ago—and in some ways it seems like an inexorable consequence of the only rather recent development of certain intuitions and tools.</p>\n<p style='font-size:90%'>The idea that the brain is fundamentally made of connected nerve cells was considered in the latter part of the nineteenth century, and took hold in the first decades of the twentieth century—with the <a href=\"https://www.wolframscience.com/nks/notes-10-12--history-of-ideas-about-thinking/\">formalized concept of a neural net</a> that operates in a computational way emerging in full form in the work of Warren McCulloch and Walter Pitts in 1943. By the late 1950s there were hardware implementations of neural nets (typically for image processing) in the form of “perceptrons”. But despite early enthusiasm, practical results were mixed, and at the end of the 1960s it was announced that simple cases amenable to mathematical analysis had been “solved”—leading to a general belief that “neural nets couldn’t do anything interesting”.</p>\n<p style='font-size:90%'>Ever since the 1940s there had been a trickle of general analyses of neural nets, particularly using methods from physics. But typically these analyses ended up with things like continuum approximations—that could say little about the information-processing aspects of neural nets. Meanwhile, there was an ongoing undercurrent of belief that somehow neural networks would both explain and reproduce how the brain works—but no methods seemed to exist to say quite how. Then at the beginning of the 1980s there was a resurgence of interest in neural networks, coming from several directions. Some of what was done concentrated on very practical efforts to get neural nets to do particular “human-like” tasks. But some was more theoretical, typically using methods from statistical physics or dynamical systems. </p>\n<p style='font-size:90%'>Before long, however, the buzz died down, and for several decades only a few groups were left working with neural nets. Then in 2011 came a surprise breakthrough in using neural nets for image analysis. It was an important practical advance. But it was driven by technological ideas and development—not any significant new theoretical analysis or framework. </p>\n<p style='font-size:90%'>And this was also the pattern for almost all of what followed. People spent great effort to come up with neural net systems that worked—and <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#the-practice-and-lore-of-neural-net-training\">all sorts of folklore</a> grew up about how this should best be done. But there wasn’t really even an attempt at an underlying theory; this was a domain of engineering practice, not basic science. </p>\n<p style='font-size:90%'>And it was in this tradition that <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">ChatGPT burst onto the scene</a> in late 2022. Almost everything about LLMs seemed to be complicated. Yes, there were empirically some large-scale regularities (like scaling laws). And I quickly suspected that the success of LLMs was a <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#what-really-lets-chatgpt-work\">strong hint of general regularities in human language</a> that hadn’t been clearly identified before. But beyond a few outlier examples, almost nothing about “what’s going on inside LLMs” has seemed easy to decode. And efforts to put “strong guardrails” on the operation of the system—in effect so as to make it in some way “predictable” or “understandable”—typically seem to substantially decrease its power (a point that now makes sense in the context of computational irreducibility).</p>\n<p style='font-size:90%'>My own interaction with machine learning and neural nets <a href=\"https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/#personal-backstory\">began in 1980</a> when I was developing my <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">SMP symbolic computation system</a>, and wondering whether it might be possible to generalize the symbolic pattern-matching foundations of the system to some kind of “fuzzy pattern matching” that would be closer to human thinking. I was aware of neural nets but thought of them as semi-realistic models of brains, not for example as potential sources of algorithms of the kind I imagined might “solve” fuzzy matching. </p>\n<p style='font-size:90%'>And it was partly as a result of trying to understand the essence of systems like neural nets that <a href=\"https://www.wolframscience.com/nks/p17--the-personal-story-of-the-science-in-this-book/\">in 1981 I came up with</a> what I later learned could be thought of as one-dimensional cellular automata. Soon I was deeply involved in studying cellular automata and developing a new intuition about how complex behavior could arise even from simple rules. But when I learned about recent efforts to make idealized models of neural nets using ideas from statistical mechanics, I was at least curious enough to set up simulations to try to understand more about these models.</p>\n<p style='font-size:90%'>But what I did wasn’t a success. I could neither get the models to do anything of significant practical interest—nor did I manage to derive any good theoretical understanding of them. I kept wondering, though, what relationship there might be between cellular automata that “just run”, and systems like neural nets that can also “learn”. And in fact <a href=\"https://content.wolfram.com/sw-publications/2020/07/approaches-complexity-engineering.pdf\">in 1985 I tried to make a minimal cellular-automaton-based model</a> to explore this. It was what I’m now calling a “vertically layered rule array”. And while in many ways I was already asking the right questions, this was an unfortunate specific choice of system—and my experiments on it didn’t reveal the kinds of phenomena we’re now seeing.</p>\n<p style='font-size:90%'>Years went by. I wrote a <a href=\"https://www.wolframscience.com/nks/chap-10--processes-of-perception-and-analysis/#sect-10-12--human-thinking\">section on “Human Thinking”</a> in <em><a href=\"https://www.wolframscience.com/nks/\">A New Kind of Science</a></em>, that discussed the possibility of simple foundational rules for the essence of thinking, and even included a minimal discrete analog of a neural net. At the time, though, I didn’t develop these ideas. By 2017, though, 15 years after the book was published—and knowing about the breakthroughs in deep learning—I had begun to <a href=\"https://writings.stephenwolfram.com/2017/05/a-new-kind-of-science-a-15-year-view/#machine-learning-and-the-neural-net-renaissance\">think more concretely about neural nets as getting their power</a> by sampling programs from across the computational universe. But still I didn’t see quite how this would work. </p>\n<p style='font-size:90%'>Meanwhile, there was a new intuition emerging from practical experience with machine learning: that if you “bashed” almost any system “hard enough”, it would learn. Did that mean that perhaps one didn’t need all the details of neural networks to successfully do machine learning? And could one perhaps make a system whose structure was simple enough that its operation would for example be accessible to visualization? I particularly wondered about this when I was writing <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">an exposition of ChatGPT and LLMs in early 2023</a>. And I kept talking about “LLM science”, but didn’t have much of a chance to work on it.</p>\n<p style='font-size:90%'>But then, a few months ago, as part of an <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/\">effort to understand the relation between what science does and what AI does</a>, I tried a kind of <a href=\"https://writings.stephenwolfram.com/2024/03/can-ai-solve-science/#exploring-spaces-of-systems\">“throwaway experiment”</a>—which, to my considerable surprise, seemed to successfully capture some of the essence of what <a href=\"https://writings.stephenwolfram.com/2024/05/why-does-biological-evolution-work-a-minimal-model-for-biological-evolution-and-other-adaptive-processes/\">makes biological evolution possible</a>. But what about other adaptive evolution—and in particular, machine learning? The models that seemed to be needed were embarrassingly close to <a href=\"https://content.wolfram.com/sw-publications/2020/07/approaches-complexity-engineering.pdf\">what I’d studied in 1985</a>. But now I had a new intuition—and, thanks to <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>, vastly better tools. And the result has been my effort here. </p>\n<p style='font-size:90%'>Of course this is only a beginning. But I’m excited to be able to see what I consider to be the beginnings of foundational science around machine learning. Already there are clear directions for practical applications (which, needless to say, I plan to explore). And there are signs that perhaps we may finally be able to understand just why—and when—the “magic” of machine learning works.</p>\n<h2 id=\"thanks\" style='font-size:1.2rem'>Thanks</h2>\n<p style='font-size:90%'>Thanks to Richard Assar of the <a href=\"https://www.wolframinstitute.org/\">Wolfram Institute</a> for extensive help.

We’ve been doing this <a href=\"https://www.wolfram.com/mathematica/scrapbook/\">since 1986</a>: continually inventing new ideas and implementing them in our larger and larger tower of technology. And it’s always very satisfying to be able to deliver our latest achievements to the world. </p>\n<p>We released <a href=\"https://reference.wolfram.com/legacy/language/v14/\">Version 14.0</a> just half a year ago. And—following our modern version scheduling—we’re now releasing Version 14.1. For most technology companies a .1 release would contain only minor tweaks. But for us it’s a snapshot of what our whole R&D pipeline has delivered—and it’s full of significant new features and new enhancements.</p>\n<p>If you’ve been following <a href=\"https://livestreams.stephenwolfram.com/\">our livestreams</a>, you may have already seen many of these features and enhancements being discussed as part of our open software design process. And we’re grateful as always to members of the Wolfram Language community who’ve made suggestions—and requests. And in fact Version 14.1 contains a particularly large number of long-requested features, some of which involved development that has taken many years and required many intermediate achievements.<span id=\"more-60695\"></span></p>\n<p>There’s lots of both extension and polishing in Version 14.1. There are a total of 89 entirely new functions—more than in any other version for the past couple of years. And there are also 137 existing functions that have been substantially updated. Along with more than 1300 distinct bug fixes and specific improvements. </p>\n<p>Some of what’s new in Version 14.1 relates to AI and LLMs. And, yes, we’re riding the leading edge of these kinds of capabilities. But the vast majority of what’s new has to do with our continued mission to bring computational language and computational knowledge to everything. And today that mission is even more important than ever, supporting not only human users, but also rapidly proliferating AI “users”—who are beginning to be able to routinely make even broader and deeper use of our technology than humans. </p>\n<p>Each new version of Wolfram Language represents a large amount of R&D by our team, and the encapsulation of a surprisingly large number of ideas about what should be implemented, and how it should be implemented. So, today, here it is: the latest stage in our four-decade journey to bring the superpower of the computational paradigm to everything. </p>\n<h2 id=\"theres-now-a-unified-wolfram-app\">There’s Now a Unified Wolfram App</h2>\n<p>In the beginning we just had “<a href=\"https://reference.wolfram.com/legacy/v1/\">Mathematica</a>”—that we described as “A System for Doing Mathematics by Computer”. But the core of “Mathematica”—based on the very general concept of transformations for symbolic expressions—was always much broader than “mathematics”. And it didn’t take long before “mathematics” was an increasingly small part of the system we had built. We <a href=\"https://writings.stephenwolfram.com/2013/02/what-should-we-call-the-language-of-mathematica/\">agonized for years about how to rebrand things</a> to better reflect what the system had become. And eventually, just over a decade ago, we did the obvious thing, and named what we had “the Wolfram Language”. </p>\n<p>But when it came to actual software products and executables, so many people were familiar with having a “Mathematica” icon on their desktop that we didn’t want to change that. Later we introduced <a href=\"https://www.wolfram.com/wolfram-one/\">Wolfram|One</a> as a general product supporting Wolfram Language across desktop and cloud—with Wolfram Desktop being its desktop component. But, yes, it’s all been a bit confusing. Ultimately there’s just one “bag of bits” that implements the whole system we’ve built, even though there are different usage patterns, and differently named products that the system supports. Up to now, each of these different products has been a different executable, that’s separately downloaded. </p>\n<p>But starting with Version 14.1 we’re unifying all these things—so that now there’s just a single unified Wolfram app, that can be configured and activated in different ways corresponding to different products.</p>\n<p>So now you just go to <a href=\"https://www.wolfram.com/download-center/\">wolfram.com/download-center</a> and download the Wolfram app:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07262024appimg1.png' alt='Wolfram app' title='Wolfram app' width='48' height='48'/></p>\n<p>After you’ve installed the app, you activate it as whatever product(s) you’ve got: Wolfram|One, Mathematica, <a href=\"https://www.wolfram.com/wolfram-alpha-notebook-edition/\">Wolfram|Alpha Notebook Edition</a>, etc. Why have separate products? Each one has a somewhat different usage pattern, and provides a somewhat different interface optimized for that usage pattern. But now the actual downloading of bits has been unified; you just have to download the unified Wolfram app and you’ll get what you need. </p>\n<h2 id=\"vector-databases-and-semantic-search\">Vector Databases and Semantic Search</h2>\n<p>Let’s say you’ve got a million documents (or webpages, or images, or whatever) and you want to find the ones that are “closest” to something. Version 14.1 now has a function—<tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt>—for doing this. How does <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> work? Basically it uses machine learning methods to find “vectors” (i.e. lists) of numbers that somehow represent the “meaning” of each of your documents. Then when you want to know which documents are “closest” to something, <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> computes the vector for the something, and then sees which of the document vectors are closest to this vector.</p>\n<p>In principle one could use <tt><a href=\"http://reference.wolfram.com/language/ref/Nearest.html\">Nearest</a></tt> to find closest vectors. And indeed this works just fine for small examples where one can readily store all the vectors in memory. But <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> uses a full industrial-strength approach based on the new vector database capabilities of Version 14.1—which can work with huge collections of vectors stored in external files. </p>\n<p>There are lots of ways to use both <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> and vector databases. You can use them to find documents, snippets within documents, images, sounds or anything else whose “meaning” can somehow be captured by a vector of numbers. Sometimes the point is to retrieve content directly for human consumption. But a particularly strong modern use case is to set up “retrieval-augmented generation” (RAG) for LLMs—in which relevant content found with a vector database is used to provide a “dynamic prompt” for the LLM. And indeed in Version 14.1—as we’ll discuss later—we now have <tt><a href=\"http://reference.wolfram.com/language/ref/LLMPromptGenerator.html\">LLMPromptGenerator</a></tt> to implement exactly this pipeline.</p>\n<p>But let’s come back to <tt><a href=\"https://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> on its own. Its basic design is modeled after <tt><a href=\"http://reference.wolfram.com/language/ref/TextSearch.html\">TextSearch</a></tt>, which does keyword-based searching of text. (Note, though, that <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> also works on many things other than text.)</p>\n<p>In direct analogy to <tt><a href=\"http://reference.wolfram.com/language/ref/CreateSearchIndex.html\">CreateSearchIndex</a></tt> for <tt><a href=\"http://reference.wolfram.com/language/ref/TextSearch.html\">TextSearch</a></tt>, there’s now a <tt><a href=\"http://reference.wolfram.com/language/ref/CreateSemanticSearchIndex.html\">CreateSemanticSearchIndex</a></tt> for <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt>. Let’s do a tiny example to see how it works. Essentially we’re going to make an (extremely restricted) “inverse dictionary”. We set up a list of definition <img style=\"margin-bottom: -1px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow2.png\" width='15' height='11' > word elements:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg1.png' alt='' title='' width='603' height='161'> </div>\n</p></div>\n<p>Now create a semantic search index from this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08082024vectorBCimg2.png' alt='' title='' width='553' height='75'> </div>\n</p></div>\n<p>Behind the scenes this is a vector database.

Instead of just using 3 words, let’s set up definitions for all words in the dictionary. It takes a little while (like a few minutes) to do the machine learning feature extraction for all the definitions. But in the end you get a new semantic search index:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08082024vectorBCimg4.png' alt='' title='' width='560' height='111'> </div>\n</p></div>\n<p>This time it has 39,186 entries—but <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> picks out the (by default) 10 that it considers closest to what you asked for (and, yes, there’s an archaic definition of “seahorse” as “walrus”):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08082024vectorBCimg5.png' alt='' title='' width='634' height='44'> </div>\n</p></div>\n<p>We can see a bit more detail about what’s going on by asking <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> to explicitly show us distances:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07303034vectorSSimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' style=\"margin-left: 5px\"src='https://content.wolfram.com/sites/43/2024/07/sw07303034vectorSSimg1A.png' alt='' title='' width='570' height='31'> <img style=\"margin-left: 5px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg6A.png' alt='SemanticSearch distances' title='SemanticSearch distances' width='595' height='81'/></div>\n</p></div>\n<p>And plotting these we can see that “whale” is the winner by a decent margin:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg7.png' alt='' title='' width='409' height='248'> </div>\n</p></div>\n<p>One subtlety when dealing with semantic search indices is where to store them. When they’re sufficiently small, you can store them directly in memory, or in a notebook. But usually you’ll want to store them in a separate file, and if you want to share an index you’ll want to put this file in the cloud. You can do this either interactively from within a notebook</p>\n<p> <img loading='lazy' style=\"margin-left: 8px\" src='https://content.wolfram.com/sites/43/2024/08/sw07302024vectorimg8B.png' alt='SemanticSearchIndex' title='SemanticSearchIndex' width='559' height='148'> </p>\n<p>or programmatically:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg9.png' alt='' title='' width='554' height='158'> </div>\n</p></div>\n<p>And now the <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearchIndex.html\">SemanticSearchIndex</a></tt> object you have can be used by anyone, with its data being accessed in the cloud.</p>\n<p>In most cases <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> will be what you need. But sometimes it’s worthwhile to “go underneath” and directly work with vector databases.

First we create the database:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08082024vectorBCimg12.png' alt='' title='' width='570' height='75'> </div>\n</p></div>\n<p>And now we can search for the nearest vector to the one we give:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07302024vectorimg13.png' alt='' title='' width='302' height='44'> </div>\n</p></div>\n<p>In this case we get exactly the same answer as from <tt><a href=\"http://reference.wolfram.com/language/ref/Nearest.html\">Nearest</a></tt>.

Fundamentally, one provides a prompt, and then the LLM generates output that “continues” that prompt. Typically the last part of the prompt is the specific question (or whatever) that a user is asking. But before that, there’ll be “pre-prompts” that prime the LLM in various ways to determine how it should respond. </p>\n<p>In <a href=\"https://reference.wolfram.com/legacy/language/v13.3/\">Version 13.3</a> in mid-2023 (i.e. a long time ago in the world of LLMs!) we introduced <tt><a href=\"http://reference.wolfram.com/language/ref/LLMPrompt.html\">LLMPrompt</a></tt> as a symbolic way to specify a prompt, and we launched the <a href=\"https://resources.wolframcloud.com/PromptRepository\">Wolfram Prompt Repository</a> as a broad source for pre-built prompts. Here’s an example of using <tt><a href=\"http://reference.wolfram.com/language/ref/LLMPrompt.html\">LLMPrompt</a></tt> with a prompt from the Wolfram Prompt Repository:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg1.png' alt='' title='' width='570' height='44'> </div>\n</p></div>\n<p>In its simplest form, <tt><a href=\"http://reference.wolfram.com/language/ref/LLMPrompt.html\">LLMPrompt</a></tt> just adds fixed text to “pre-prompt” the LLM. <tt><a href=\"http://reference.wolfram.com/language/ref/LLMPrompt.html\">LLMPrompt</a></tt> is also set up to take arguments that modify the text it’s adding:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg2.png' alt='' title='' width='607' height='43'> </div>\n</p></div>\n<p>But what if one wants the LLM to be pre-prompted in a way that depends on information that’s only available once the user actually asks their question (like, for example, the text of the question itself)? In Version 14.1 we’re adding <tt><a href=\"http://reference.wolfram.com/language/ref/LLMPromptGenerator.html\">LLMPromptGenerator</a></tt> to dynamically generate pre-prompts. And it turns out that this kind of “dynamic prompting” is remarkably powerful, and—particularly together with tool calling—opens up a whole new level of capabilities for LLMs. </p>\n<p>For example, we can set up a prompt generator that produces a pre-prompt that gives the registered name of the user, so the LLM can use this information when generating its answer:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg3.png' alt='' title='' width='599' height='115'> </div>\n</p></div>\n<p>Or for example here the prompt generator is producing a pre-prompt about sunrise, sunset and the current time:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg4.png' alt='' title='' width='499' height='138'> </div>\n</p></div>\n<p>And, yes, if the pre-prompt contains extra information (like about the Moon) the LLM will (probably) ignore it:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg5.png' alt='' title='' width='479' height='161'> </div>\n</p></div>\n<p>As another example, we can take whatever the user asks, and first do a web search on it, then include as a pre-prompt snippets we get from the web. The result is that we can get answers from the LLM that rely on specific “web knowledge” that we can’t expect will be “known in detail” by the raw LLM:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg6.png' alt='' title='' width='582' height='208'> </div>\n</p></div>\n<p>But often one doesn’t want to just “search at random on the web”; instead one wants to systematically retrieve information from some known source to give as “briefing material” to the LLM to help it in generating its answer. And a typical way to implement this kind of “retrieval-augmented generation (RAG)” is to set up an <tt><a href=\"http://reference.wolfram.com/language/ref/LLMPromptGenerator.html\">LLMPromptGenerator</a></tt> that uses the <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> and vector database capabilities that we introduced in Version 14.1.</p>\n<p>So, for example, here’s a semantic search index generated from my (rather voluminous) writings:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg7.png' alt='' title='' width='604' height='75'> </div>\n</p></div>\n<p>By setting up a prompt generator based on this, I can now ask the LLM “personal questions”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg8.png' alt='' title='' width='513' height='68'> </div>\n</p></div>\n<p>How did the LLM “know that”? Internally the prompt generator used <tt><a href=\"http://reference.wolfram.com/language/ref/SemanticSearch.html\">SemanticSearch</a></tt> to generate a collection of snippets, which the LLM then “trawled through” to produce a specific answer:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg9.png' alt='' title='' width='440' height='14'><img loading='lazy' style=\"margin-left: -3px\" src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg9B.png' alt='' title='' width='500' height='204'> </div>\n</p></div>\n<p>It’s already often very useful just to “retrieve static text” to “brief” the LLM. But even more powerful is to brief the LLM with what it needs to call tools that can do further computation, etc. So, for example, if you want the LLM to write and run Wolfram Language code that uses functions you’ve created, you can do that by having it first “read the documentation” for those functions.</p>\n<p>As an example, this uses a prompt generator that uses a semantic search index built from the <a href=\"https://resources.wolframcloud.com/FunctionRepository/\">Wolfram Function Repository</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg10A_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07282024RAGsimg10A.png' alt='' title='' width='674' height='242'> </div>\n</p></div>\n<h2 id=\"connect-to-your-favorite-llm\">Connect to Your Favorite LLM</h2>\n<p>There are now many ways to use LLM functionality from within the Wolfram Language, and <a href=\"https://www.wolfram.com/notebooks/\">Wolfram Notebooks</a>. You can do it programmatically, with <tt><a href=\"http://reference.wolfram.com/language/ref/LLMFunction.html\">LLMFunction</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/LLMSynthesize.html\">LLMSynthesize</a></tt>, etc. You can do it interactively through <a href=\"https://writings.stephenwolfram.com/2023/06/introducing-chat-notebooks-integrating-llms-into-the-notebook-paradigm/\">Chat Notebooks</a> and related chat capabilities.</p>\n<p>But (at least for now) there’s no full-function LLM built directly into the Wolfram Language. So that means that (at least for now) you have to choose your “flavor” of external LLM to power Wolfram Language LLM functionality.

But in fact we have recently been mired in an intense debate about binomial coefficients—which has caused us in Version 14.1 to introduce a new function <tt><a href=\"http://reference.wolfram.com/language/ref/PascalBinomial.html\">PascalBinomial</a></tt> alongside our existing <tt><a href=\"http://reference.wolfram.com/language/ref/Binomial.html\">Binomial</a></tt>.</p>\n<p>When one’s dealing with positive integer arguments, there’s no issue with binomials. And even when one extends to generic complex arguments, there’s again a unique way to do this. But negative integer arguments are a special degenerate case. And that’s where there’s trouble—because there are two different definitions that have historically been used.</p>\n<p>In early versions of Mathematica, we picked one of these definitions. But over time we realized that it led to some subtle inconsistencies, and so for <a href=\"https://reference.wolfram.com/legacy/v7/guide/Mathematica.html\">Version 7</a>—in 2008—we changed to the other definition. Some of our users were happy with the change, but some were definitely not. A notable (vociferous) example was my friend <a href=\"https://www.wolframalpha.com/input?i=don+knuth\">Don Knuth</a>, who has written several well-known books that make use of binomial coefficients—always choosing what amounts to our pre-2008 definition. </p>\n<p>So what could we do about this? For a while we thought about adding an option to <tt><a href=\"http://reference.wolfram.com/language/ref/Binomial.html\">Binomial</a></tt>, but to do this would have broken our normal conventions for mathematical functions. And somehow we kept on thinking that there was ultimately a “right answer” to how binomial coefficients should be defined. But after a lot of discussion—and historical research—we finally concluded that since at least before 1950 there have just been two possible definitions, each with their own advantages and disadvantages, with no obvious “winner”. And so in Version 14.1 we decided just to introduce a new function <tt><a href=\"http://reference.wolfram.com/language/ref/PascalBinomial.html\">PascalBinomial</a></tt> to cover the “other definition”. </p>\n<p>And—though at first it might not seem like much—here’s a big difference between <tt><a href=\"http://reference.wolfram.com/language/ref/Binomial.html\">Binomial</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/PascalBinomial.html\">PascalBinomial</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg1.png' alt='' title='' width='170' height='43'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg2.png' alt='' title='' width='215' height='43'> </div>\n</p></div>\n<p>Part of why things get complicated is the relation to symbolic computation. <tt><a href=\"http://reference.wolfram.com/language/ref/Binomial.html\">Binomial</a></tt> has a symbolic simplification rule, valid for any <em>n</em>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg3.png' alt='' title='' width='149' height='43'> </div>\n</p></div>\n<p>But there isn’t a corresponding generic simplification rule for <tt><a href=\"http://reference.wolfram.com/language/ref/PascalBinomial.html\">PascalBinomial</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg4.png' alt='' title='' width='193' height='44'> </div>\n</p></div>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/FunctionExpand.html\">FunctionExpand</a></tt> shows us the more nuanced result in this case:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg5.png' alt='' title='' width='419' height='61'> </div>\n</p></div>\n<p>To see a bit more of what’s going on, we can compute arrays of nonzero results for <tt><a href=\"http://reference.wolfram.com/language/ref/Binomial.html\">Binomial</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/PascalBinomial.html\">PascalBinomial</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07272024binomialsimg6.png' alt='' title='' width='661' height='297'> </div>\n</p></div>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/Binomial.html\">Binomial</a></tt><tt>[n, k]</tt> has the “nice feature” that it’s symmetric in <em>k</em> even when <em>n</em> < 0.

For example, their “zero” shifts around depending on the calendar. And their granularity is more complicated than precision for numbers. In addition, a single date can have multiple different representations (say in different calendars or with different granularities). But it nevertheless turns out to be possible to define many kinds of statistics for dates. To understand these statistics—and to compute them—it’s typically convenient to make one’s whole collection of dates have the same form. And in Version 14.1 this can be achieved with the new function <a href=\"https://reference.wolfram.com/language/ref/ConformDates.html\"><tt>ConformDates</tt></a> (which here converts all dates to the format of the first one listed):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024datesimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024datesimg4.png' alt='' title='' width='570' height='58'> </div>\n</p></div>\n<p>By the way, in Version 14.1 the whole pipeline for handling dates (and times) has been dramatically speeded up, most notably conversion from strings, as needed in the import of dates. </p>\n<p>The concept of doing statistics on dates introduces another new idea: date (and time) distributions. And in Version 14.1 there are two new functions <a href=\"http://reference.wolfram.com/language/ref/DateDistribution.html\"><tt>DateDistribution</tt></a> and <a href=\"http://reference.wolfram.com/language/ref/TimeDistribution.html\"><tt>TimeDistribution</tt></a> for defining such distributions. Unlike for numerical (or quantity) distributions, date and time distributions require the specification of an origin, like <tt><a href=\"http://reference.wolfram.com/language/ref/Today.html\">Today</a></tt>, as well as of a scale, like <tt>\"Days\"</tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024datesimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024datesimg5.png' alt='' title='' width='466' height='88'> </div>\n</p></div>\n<p>But given this symbolic specification, we can now do operations just like for any other distribution, say generating some random variates: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024datesimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024datesimg6.png' alt='' title='' width='734' height='48'> </div>\n</p></div>\n<h2 id=\"building-videos-with-programs\">Building Videos with Programs</h2>\n<p>Introduced in <a href=\"https://reference.wolfram.com/legacy/v6/guide/Mathematica.html\">Version 6</a> back in 2007, <tt><a href=\"http://reference.wolfram.com/language/ref/Manipulate.html\">Manipulate</a></tt> provides an immediate way to create an interactive “manipulable” interface. And it’s been possible for a long time to export <tt><a href=\"http://reference.wolfram.com/language/ref/Manipulate.html\">Manipulate</a></tt> objects to video. But just what should happen in the video? What sliders should move in what way? In <a href=\"https://reference.wolfram.com/legacy/language/v12.3/\">Version 12.3</a> we introduced <tt><a href=\"http://reference.wolfram.com/language/ref/AnimationVideo.html\">AnimationVideo</a></tt> to let you make a video in which one parameter is changing with time. But now in Version 14.1 we have <tt><a href=\"http://reference.wolfram.com/language/ref/ManipulateVideo.html\">ManipulateVideo</a></tt> which lets you create a video in which many parameters can be varied simultaneously. One way to specify what you want is to say for each parameter what value it should get at a sequence of times (by default measured in seconds from the beginning of the video). <tt><a href=\"http://reference.wolfram.com/language/ref/ManipulateVideo.html\">ManipulateVideo</a></tt> then produces a smooth video by interpolating between these values:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024videoimg1_copy.txt' data-c2c-type='text/html'> <video autoplay width=\"567\" height=\"495\" loop><source src=\"https://content.wolfram.com/sites/43/2024/07/manipulatevideo.mp4\" type=\"video/mp4\"></video></div>\n<div>\n<p>(An alternative is to specify complete “keyframes” by giving operations to be done at particular times.) </p>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/ManipulateVideo.html\">ManipulateVideo</a></tt> in a sense provides a “holistic” way to create a video by controlling a <tt><a href=\"http://reference.wolfram.com/language/ref/Manipulate.html\">Manipulate</a></tt>. And in the last several versions we’ve introduced many functions for creating videos from “existing structures” (for example <tt><a href=\"http://reference.wolfram.com/language/ref/FrameListVideo.html\">FrameListVideo</a></tt> assembles a video from a list of frames). But sometimes you want to build up videos one frame at a time. And in Version 14.1 we’ve introduced <tt><a href=\"http://reference.wolfram.com/language/ref/SowVideo.html\">SowVideo</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/ReapVideo.html\">ReapVideo</a></tt> for doing this.

And now in Version 14.1 <tt><a href=\"http://reference.wolfram.com/language/ref/SpeechRecognize.html\">SpeechRecognize</a></tt> is getting a makeover. </p>\n<p>The most dramatic change is speed. In the past, <tt><a href=\"http://reference.wolfram.com/language/ref/SpeechRecognize.html\">SpeechRecognize</a></tt> would typically take at least as long to recognize a piece of speech as the duration of the speech itself. But now in Version 14.1, <tt><a href=\"http://reference.wolfram.com/language/ref/SpeechRecognize.html\">SpeechRecognize</a></tt> runs many tens of times faster, so you can recognize speech much faster than real time.</p>\n<p>And what’s more, <tt><a href=\"http://reference.wolfram.com/language/ref/SpeechRecognize.html\">SpeechRecognize</a></tt> now produces full, written text, complete with capitalization, punctuation, etc. So here, for example, is a transcription of <a href=\"https://www.wolframcloud.com/obj/5f070490-8074-441c-beba-9490d95e125a\">a little video</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024speechNewC2Cimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07302024speechBimg1.png' alt='' title='' width='527' height='166'> </div>\n</p></div>\n<p>There’s also a new function, <tt><a href=\"http://reference.wolfram.com/language/ref/VideoTranscribe.html\">VideoTranscribe</a></tt>, that will take a video, transcribe its audio, and insert the transcription back into the subtitle track of the video.</p>\n<p>And, by the way, <tt><a href=\"http://reference.wolfram.com/language/ref/SpeechRecognize.html\">SpeechRecognize</a></tt> runs entirely locally on your computer, without having to access a server (except maybe for updates to the neural net it’s using). </p>\n<p>In the past <tt><a href=\"http://reference.wolfram.com/language/ref/SpeechRecognize.html\">SpeechRecognize</a></tt> could only handle English. In Version 14.1 it can handle 100 languages—and can automatically produce translated transcriptions. (By default it produces transcriptions in the language you’ve specified with <tt><a href=\"http://reference.wolfram.com/language/ref/$Language.html\">$Language</a></tt>.) And if you want to identify what language a piece of audio is in, <tt><a href=\"http://reference.wolfram.com/language/ref/LanguageIdentify.html\">LanguageIdentify</a></tt> now works directly on audio.</p>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/SpeechRecognize.html\">SpeechRecognize</a></tt> by default produces a single string of text.

But that doesn’t mean there isn’t much that can be made computable about it. And in Version 14.1 we’re taking a major step forward in making historical geography computable. We’ve had extensive geographic computation capabilities in the Wolfram Language for well over a decade. And in Version 14.1 we’re extending that to historical geography.</p>\n<p>So now you can not only ask for a map of where the current country of Italy is, you can also ask to make a map of the Roman Empire in 100 AD:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg1.png' alt='' title='' width='558' height='338'> </div>\n</p></div>\n<p>And “the Roman Empire in 100 AD” is now a computable entity.

Of course, country borders may be disputed, and—particularly in the more distant past—may not have been well defined. But by now we’ve accumulated computable data on basically all of the few thousand known historical countries. Still—with history being complicated—it’s not surprising that there are all sorts of often subtle issues.</p>\n<p>Let’s start by asking what historical countries the location that’s now Mexico City has been in. <tt><a href=\"http://reference.wolfram.com/language/ref/GeoIdentify.html\">GeoIdentify</a></tt> gives the answer:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg4.png' alt='' title='' width='606' height='102'> </div>\n</p></div>\n<p>And already we see subtlety. For example, our historical country entities are labeled by their overall beginning and ending dates. But most of them covered Mexico City only for part of their existence. And here we can see what’s going on:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg6.png' alt='' title='' width='483' height='25'><img style=\"margin-left: -3px\"src='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg5A.png' alt='' title='' width='542' height='225'/> </div>\n</p></div>\n<p>Often there’s subtlety in identifying what should count as a “different country”. If there was just an “acquisition” or a small “change of management” maybe it’s still the same country. But if there was a “dramatic reorganization”, maybe it’s a different country. Sometimes the names of countries (if they even had official names) give clues. But in general it’s taken lots of case-by-case curation, trying to follow the typical conventions used by historians of particular times and places. </p>\n<p>For London we see several “close-but-we-consider-it-a-different-country” issues—along with various confusing repeated conquerings and reconquerings:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg7.png' alt='' title='' width='651' height='244'> </div>\n</p></div>\n<p>Here’s a timeline plot of the countries that have contained London:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg8.png' alt='' title='' width='504' height='711'> </div>\n</p></div>\n<p>And because everything is computable, it’s easy to identify the longest contiguous segment here:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07292024geographyimg9.png' alt='' title='' width='609' height='121'> </div>\n</p></div>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/GeoIdentify.html\">GeoIdentify</a></tt> can tell us what entities something like a city is inside. <tt><a href=\"http://reference.wolfram.com/language/ref/GeoEntities.html\">GeoEntities</a></tt>, on the other hand, can tell us what entities are inside something like a country.

There are four main coordinate systems that get used in doing this: horizon (relative to local horizon), equatorial (relative to the Earth’s equator), ecliptic (relative to the orbit of the Earth around the Sun) and galactic (relative to the plane of the galaxy). And when we draw a diagram of the sky (here on white for clarity) it’s typical to show the “axes” for all these coordinate systems:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07272024astroimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07272024astroimg1.png' alt='' title='' width='667' height='674'> </div>\n</p></div>\n<p>But here’s a tricky thing: how should those axes be labeled? Each one is different: horizon is most naturally labeled by things like cardinal directions (N, E, S, W, etc.), equatorial by hours in the day (in sidereal time), ecliptic by months in the year, and galactic by angle from the center of the galaxy. </p>\n<p>In ordinary plots axes are usually straight, and labeled uniformly (or perhaps, say, logarithmically). But in astronomy things are much more complicated: the axes are intrinsically circular, and then get rendered through whatever projection we’re using.</p>\n<p>And we might have thought that such axes would require some kind of custom structure. But not in the Wolfram Language. Because in the Wolfram Language we try to make things general.

We’ve thought about it for a long time (and by “long” I mean decades). And finally now in Version 14.1 we have a solution—that I think is very nice and very convenient. The core of it is a new notebook-oriented analog of <tt>%</tt>, that lets one refer not just to things like “the last result that was computed” but instead to things like “the result computed in a particular cell in the notebook”.</p>\n<p>So let’s look at our sequence from above again. Let’s start typing another cell—say to “try to get it right”.

Let’s pick the last one listed:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg4.png' alt='Last menu option' title='Last menu option' width='377' height='94'/></p>\n<p>The <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg6.png' alt='' title='' width='20' height='13'/> object is a reference to the output from the cell that’s currently labeled <tt>In[1]</tt>—and using <img loading='lazy' style=\"margin-bottom: -3px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg6.png' alt='' title='' width='20' height='13'/> now gives us what we wanted.</p>\n<p>But let’s say we go back and change the first (input) cell in the notebook—and reevaluate it:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/GIFflow1.gif' alt='Reevaluate Range' title='Reevaluate Range' width='377' height='82'></p>\n<p>The cell now gets labeled <tt>In[5]</tt>—and the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg6.png' alt='' title='' width='20' height='13'/> (in <tt>In[4]</tt>) that refers to that cell will immediately change to <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg9.png' alt='' title='' width='19' height='12'/>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg10.png' alt='Median' title='Median' width='377' height='52'/></p>\n<p>And if we now evaluate this cell, it’ll pick up the value of the output associated with <tt>In[5]</tt>, and give us a new answer:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg11.png' alt='New answer' title='New answer' width='377' height='84'/></p>\n<p>So what’s really going on here? The key idea is that <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg12.png' alt='' title='' width='13' height='14'/> signifies a new type of notebook element that’s a kind of cell-linked analog of <tt>%</tt>. It represents the latest result from evaluating a particular cell, wherever the cell may be, and whatever the cell may be labeled. (The <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg13.png' alt='' title='' width='13' height='14'/> object always shows the current label of the cell it’s linked to.) In effect <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg14.png' alt='' title='' width='17' height='14'/> is “notebook front end oriented”, while ordinary <tt>%</tt> is kernel oriented. <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg15.png' alt='' title='' width='17' height='14'/> is linked to the contents of a particular cell in a notebook; <tt>%</tt> refers to the state of the Wolfram Language kernel at a certain time. </p>\n<p><img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg16.png' alt='' title='' width='17' height='14'/> gets updated whenever the cell it’s referring to is reevaluated. So its value can change either through the cell being explicitly edited (as in the example above) or because reevaluation gives a different value, say because it involves generating a random number:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/GlFflow2.gif' alt='RandomInteger' title='RandomInteger' width='377' height='167'></p>\n<p>OK, so <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg18.png' alt='' title='' width='17' height='14'/> always refers to “a particular cell”. But what makes a cell a particular cell? It’s defined by a unique ID that’s assigned to every cell. When a new cell is created it’s given a universally unique ID, and it carries that same ID wherever it’s placed and whatever its contents may be (and even across different sessions). If the cell is copied, then the copy gets a new ID. And although you won’t explicitly see cell IDs, <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg19.png' alt='' title='' width='17' height='14'/> works by linking to a cell with a particular ID. </p>\n<p>One can think of <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg20.png' alt='' title='' width='17' height='14'/> as providing a “more stable” way to refer to outputs in a notebook. And actually, that’s true not just within a single session, but also across sessions. Say one saves the notebook above and opens it in a new session. Here’s what you’ll see:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg21.png' alt='Saving across sessions' title='Saving across sessions' width='377' height='180'/></p>\n<p>The <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg22.png' alt='' title='' width='17' height='14'/> is now grayed out. So what happens if we try to reevaluate it? Well, we get this:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/08/sw07302023flowimg23A.png' alt='Reconstruct or reevaluate' title='Reconstruct or reevaluate' width='614' height='146'/></p>\n<p>If we press <span class=\"kbd\"><kbd>Reconstruct from output cell</kbd></span> the system will take the contents of the first output cell that was saved in the notebook, and use this to get input for the cell we’re evaluating:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg25.png' alt='Reconstruct from output cell' title='Reconstruct from output cell' width='377' height='91'/></p>\n<p>In almost all cases the contents of the output cell will be sufficient to allow the expression “behind it” to be reconstructed. But in some cases—like when the original output was too big, and so was elided—there won’t be enough in the output cell to do the reconstruction. And in such cases it’s time to take the <span class=\"kbd\"><kbd>Go to input cell</kbd></span> branch, which in this case will just take us back to the first cell in the notebook, and let us reevaluate it to recompute the output expression it gives.</p>\n<p>By the way, whenever you see a “positional <tt>%</tt>” you can hover over it to highlight the cell it’s referring to:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/GIFflow3.gif' alt='Positional % highlighting' title='Positional % highlighting' width='377' height='180'></p>\n<p>Having talked a bit about “cell-linked <tt>%</tt>” it’s worth pointing out that there are still cases when you’ll want to use “ordinary <tt>%</tt>”. A typical example is if you have an input line that you’re using a bit like a function (say for post-processing) and that you want to repeatedly reevaluate to see what it produces when applied to your latest output. </p>\n<p>In a sense, ordinary <tt>%</tt> is the “most volatile” in what it refers to. Cell-linked <tt>%</tt> is “less volatile”. But sometimes you want no volatility at all in what you’re referring to; you basically just want to burn a particular expression into your notebook. And in fact the <tt>%</tt> autosuggest menu gives you a way to do just that. </p>\n<p>Notice the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg27.png' alt='' title='' width='21' height='15'/> that appears in whatever row of the menu you’re selecting:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/MedianPointer.png' alt='Iconize option' title='Iconize option' width='440' height='155'/></p>\n<p>Press this and you’ll insert (in iconized form) the whole expression that’s being referred to:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg29.png' alt='Iconized expression' title='Iconized expression' width='377' height='70'/></p>\n<p>Now—for better or worse—whatever changes you make in the notebook won’t affect the expression, because it’s right there, in literal form, “inside” the icon. And yes, you can explicitly “uniconize” to get back the original expression:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/diffMedianswooshA.png' alt='Uniconize' title='Uniconize' width='663' height='140'/></p>\n<p>Once you have a cell-linked <tt>%</tt> it always has a contextual menu with various actions:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg31.png' alt='Contextual menu' title='Contextual menu' width='407' height='186'/></p>\n<p>One of those actions is to do what we just mentioned, and replace the positional <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg32.png' alt='' title='' width='17' height='14'/> by an iconized version of the expression it’s currently referring to. You can also highlight the output and input cells that the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg32.png' alt='' title='' width='17' height='14'/> is “linked to”. (Incidentally, another way to replace a <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg33.png' alt='' title='' width='17' height='14'/> by the expression it’s referring to is simply to “evaluate in place” <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg34.png' alt='' title='' width='17' height='14'/>, which you can do by selecting it and pressing <span class=\"kbd\"><kbd>CMD</kbd><kbd>Return</kbd></span> or <span class=\"kbd\"><kbd>Shift</kbd><kbd>Control</kbd><kbd>Enter</kbd></span>.)</p>\n<p>Another item in the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg35.png' alt='' title='' width='13' height='14'/> menu is <span class=\"kbd\"><kbd>Replace With Rolled-Up Inputs</kbd></span>. What this does is—as it says—to “roll up” a sequence of “<img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg36.png' alt='' title='' width='13' height='14'/> references” and create a single expression from them:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg37.png' alt='Replace with rolled-up inputs' title='Replace with rolled-up inputs' width='499' height='525'/></p>\n<p>What we’ve talked about so far one can think of as being “normal and customary” uses of <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg38.png' alt='' title='' width='13' height='14'/>. But there are all sorts of corner cases that can show up. For example, what happens if you have a <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg39.png' alt='' title='' width='17' height='14'/> that refers to a cell you delete? Well, within a single (kernel) session that’s OK, because the expression “behind” the cell is still available in the kernel (unless you reset your <tt><a href=\"http://reference.wolfram.com/language/ref/$HistoryLength.html\">$HistoryLength</a></tt> etc.). Still, the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg40.png' alt='' title='' width='17' height='14'/> will show up with a “red broken link” to indicate that “there could be trouble”:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg41.png' alt='Red broken link' title='Red broken link' width='91' height='36'/></p>\n<p>And indeed if you go to a different (kernel) session there will be trouble—because the information you need to get the expression to which the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg42.png' alt='' title='' width='17' height='14'/> refers is simply no longer available, so it has no choice but to show up in a kind of everything-has-fallen-apart “surrender state” as:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg43.png' alt='Surrender state' title='Surrender state' width='87' height='36'/></p>\n<p><img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg44.png' alt='' title='' width='13' height='14'/> is primarily useful when it refers to cells in the notebook you’re currently using (and indeed the autosuggest menu will contain only cells from your current notebook). But what if it ends up referring to a cell in a different notebook, say because you copied the cell from one notebook to another? It’s a precarious situation. But if all relevant notebooks are open, <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg45.png' alt='' title='' width='17' height='14'/> can still work, though it’s displayed in purple with an action-at-a-distance “wi-fi icon” to indicate its precariousness:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg46.png' alt='Wi-fi icon' title='Wi-fi icon' width='74' height='18'/></p>\n<p>And if, for example, you start a new session, and the notebook containing the “source” of the <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg47.png' alt='' title='' width='17' height='14'/> isn’t open, then you’ll get the “surrender state”. (If you open the necessary notebook it’ll “unsurrender” again.)</p>\n<p>Yes, there are lots of tricky cases to cover (in fact, many more than we’ve explicitly discussed here). And indeed seeing all these cases makes us not feel bad about how long it’s taken for us to conceptualize and implement <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg48.png' alt='' title='' width='13' height='14'/>. </p>\n<p>The most common way to access <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg49.png' alt='' title='' width='17' height='14'/> is to use the <tt>%</tt> autosuggest menu. But if you know you want a <img loading='lazy' style=\"margin-bottom: -2px\" src='https://content.wolfram.com/sites/43/2024/07/sw07302023flowimg50.png' alt='' title='' width='17' height='14'/>, you can always get it by “pure typing”, using for example <span class=\"kbd\"><kbd>ESC</kbd><kbd><tt>%</tt></kbd><kbd>ESC</kbd></span>. (And, yes, <span class=\"kbd\"><kbd>ESC</kbd><kbd><tt>%%</tt></kbd><kbd>ESC</kbd></span> or <span class=\"kbd\"><kbd>ESC</kbd><kbd><tt>%</tt>5</kbd><kbd>ESC</kbd></span> etc. also work, so long as the necessary cells are present in your notebook.)</p>\n<h2 id=\"the-ux-journey-continues-new-typing-affordances-and-more\">The UX Journey Continues: New Typing Affordances, and More</h2>\n<p>We invented <a href=\"https://www.wolfram.com/notebooks/\">Wolfram Notebooks</a> more than 36 years ago, and we’ve been improving and polishing them ever since. And in Version 14.1 we’re implementing several new ideas, particularly around making it even easier to type Wolfram Language code.</p>\n<p>It’s worth saying at the outset that good UX ideas quickly become essentially invisible. They just give you hints about how to interpret something or what to do with it. And if they’re doing their job well, you’ll barely notice them, and everything will just seem “obvious”. </p>\n<p>So what’s new in UX for Version 14.1? First, there’s a story around brackets. We first introduced syntax coloring for unmatched brackets back in the late 1990s, and gradually polished it over the following two decades. Then in 2021 we started “automatching” brackets (and other delimiters), so that as soon as you type “f[” you immediately get <tt>f[ ]</tt>.</p>\n<p>But how do you keep on typing? You could use an <span class=\"kbd\"><kbd><img style=\"margin-bottom: -1px\" class='' src=\"https://content.wolfram.com/uploads/sites/32/2022/10/rightarrow2.png\" width='15' height='11' ></kbd></span> to “move through” the <tt>]</tt>. But we’ve set it up so you can just “type through” <tt>]</tt> by typing <span class=\"kbd\"><kbd>]</kbd></span>. In one of those typical pieces of UX subtlety, however, “type through” doesn’t always make sense. For example, let’s say you typed <tt>f[x]</tt>. Now you click right after <tt>[</tt> and you type <tt>g[</tt>, so you’ve got <tt>f[g[x]</tt>. You might think there should be an autotyped <tt>]</tt> to go along with the <tt>[</tt> after <tt>g</tt>. But where should it go? Maybe you want to get <tt>f[g[x]]</tt>, or maybe you’re really trying to type <tt>f[g[],x]</tt>. We definitely don’t want to autotype <tt>]</tt> in the wrong place. So the best we can do is not autotype anything at all, and just let you type the <tt>]</tt> yourself, where you want it. But remember that with <tt>f[x]</tt> on its own, the <tt>]</tt> is autotyped, and so if you type <span class=\"kbd\"><kbd>]</kbd></span> yourself in this case, it’ll just type through the autotyped <tt>]</tt> and you won’t explicitly see it.</p>\n<p>So how can you tell whether a ] you type will explicitly show up, or will just be “absorbed” as type-through? In Version 14.1 there’s now different syntax coloring for these cases: yellow if it’ll be “absorbed”, and pink if it’ll explicitly show up. </p>\n<p>This is an example of non-type-through, so <tt><a href=\"http://reference.wolfram.com/language/ref/Range.html\">Range</a></tt> is colored yellow and the <span class=\"kbd\"><kbd>]</kbd></span> you type is “absorbed”:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/syntaxGIF1.gif' alt='Range highlighted yellow' title='Range highlighted yellow' width='77' height='19'></p>\n<p>And this is an example of non-type-through, so <tt><a href=\"http://reference.wolfram.com/language/ref/Round.html\">Round</a></tt> is colored pink and the <span class=\"kbd\"><kbd>]</kbd></span> you type is explicitly inserted:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/syntaxGIF2.gif' alt='Round highlighted pink' title='Round highlighted pink' width='124' height='16'></p>\n<p>This may all sound very fiddly and detailed—and for us in developing it, it is. But the point is that you don’t explicitly have to think about it. You quickly learn to just “take the hint” from the syntax coloring about when your closing delimiters will be “absorbed” and when they won’t. And the result is that you’ll have an even smoother and faster typing experience, with even less chance of unmatched (or incorrectly matched) delimiters.</p>\n<p>The new syntax coloring we just discussed helps in typing code. In Version 14.1 there’s also something new that helps in reading code. It’s an enhanced version of something that’s actually common in IDEs: when you click (or select) a variable, every instance of that variable immediately gets highlighted:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/syntaxGIF3A.gif' alt='Highlighted variable' title='Highlighted variable' width='592' height='234'></p>\n<p>What’s subtle in our case is that we take account of the scoping of localized variables—putting a more colorful highlight on instances of a variable that are in scope:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302024UXimg4.png' alt='Multiple instances of a variable' title='Multiple instances of a variable' width='537' height='85'/></p>\n<p>One place this tends to be particularly useful is in understanding nested pure functions that use <tt>#</tt>. By clicking a <tt>#</tt> you can see which other instances of <tt>#</tt> are in the same pure function, and which are in different ones (the highlight is bluer inside the same function, and grayer outside):</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302024UXimg5.png' alt='Highlighting in nested functions' title='Highlighting in nested functions' width='304' height='14'/></p>\n<p>On the subject of finding variables, another change in Version 14.1 is that fuzzy name autocompletion now also works for contexts. So if you have a symbol whose full name is <tt>context1`subx`var2</tt> you can type <tt>c1x</tt> and you’ll get a completion for the context; then accept this and you get a completion for the symbol.</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07302024UXimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08142024UXBCimg6.png' alt='' title='' width='183' height='43'> </div>\n</p></div>\n<p>There are also several other notable UX “tune-ups” in Version 14.1. For many years, there’s been an “information box” that comes up whenever you hover over a symbol. Now that’s been extended to entities—so (alongside their explicit form) you can immediately get to information about them and their properties:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302024UXimg7.png' alt='Entity information box' title='Entity information box' width='352' height='45'/></p>\n<p>Next there’s something that, yes, I personally have found frustrating in the past. Say you’ve a file, or an image, or something else somewhere on your computer’s desktop. Normally if you want it in a Wolfram Notebook you can just drag it there, and it will very beautifully appear. But what if the thing you’re dragging is very big, or has some other kind of issue? In the past, the drag just failed. Now what happens is that you get the explicit <tt><a href=\"http://reference.wolfram.com/language/ref/Import.html\">Import</a></tt> that the dragging would have done, so that you can run it yourself (getting progress information, etc.), or you can modify it, say adding relevant options. </p>\n<p>Another small piece of polish that’s been added in Version 14.1 has to do with <tt>Preferences</tt>. There are a lot of things you can set in the notebook front end. And they’re explained, at least briefly, in the many <tt>Preferences</tt> panels. But in Version 14.1 there are now <span class=\"kbd\"><kbd>(i)</kbd></span> buttons that give direct links to the relevant workflow documentation:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07302024UXimg8.png' alt='Direct link to workflow documentation' title='Direct link to workflow documentation' width='619' height='167'/></p>\n<h2 id=\"syntax-for-natural-language-input\">Syntax for Natural Language Input</h2>\n<p>Ever since shortly after <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a> was released in 2009, there’ve been ways to access its natural language understanding capabilities in the Wolfram Language. Foremost among these has been <span class=\"kbd\"><kbd>CTRL</kbd><kbd>=</kbd></span>—which lets you type free-form natural language and immediately get a Wolfram Language version, often in terms of entities, etc.:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024syntaximg1.png' alt='Wolfram|Alpha entities' title='Wolfram|Alpha entities' width='453' height='24'></p>\n<p>Generally this is a very convenient and elegant capability. But sometimes one may want to just use plain text to specify natural language input, for example so that one doesn’t interrupt one’s textual typing of input.</p>\n<p>In Version 14.1 there’s a new mechanism for this: syntax for directly entering free-form natural language input. The syntax is a kind of a “textified” version of <span class=\"kbd\"><kbd>CTRL</kbd><kbd>=</kbd></span>: <tt>=[…]</tt>. When you type <tt>=[...]</tt> as input nothing immediately happens. It’s only when you evaluate your input that the natural language gets interpreted—and then whatever it specifies is computed.</p>\n<p>Here’s a very simple example, where each <tt>=[…]</tt> just turns into an entity:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024syntaximg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024syntaximg2.png' alt='' title='' width='227' height='54'> </div>\n</p></div>\n<p>But when the result of interpreting the natural language is an expression that can be further evaluated, what will come out is the result of that evaluation:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024syntaximg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024syntaximg3.png' alt='' title='' width='418' height='55'> </div>\n</p></div>\n<p>One feature of using <tt>=[…]</tt> instead of <span class=\"kbd\"><kbd>CTRL</kbd><kbd>=</kbd></span> is that <tt>=[…]</tt> is something anyone can immediately see how to type:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024syntaximg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024syntaximg4.png' alt='' title='' width='518' height='267'> </div>\n</p></div>\n<p>But what actually is <tt>=[…]</tt>?

It’s fairly easy to do “diffs” for plain text. But for notebooks—as structured symbolic documents—it’s a much more complicated story. But in Version 14.1 it’s here! We’ve got a function <tt><a href=\"http://reference.wolfram.com/language/ref/Diff.html\">Diff</a></tt> for doing diffs in notebooks, and actually also in many other kinds of things. </p>\n<p>Here’s an example, where we’re requesting a “side-by-side view” of the diff between two notebooks:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08142024diffUPDATEimg1.png' alt='' title='' width='438' height='184'/> </div>\n</p></div>\n<p>And here’s an “alignment chart view” of the diff:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08142024diffUPDATEimg2.png' alt='Click to enlarge' title='Click to enlarge' width='415' height='176'/> </div>\n</p></div>\n<p>Like everything else in the Wolfram Language, a “diff” is a symbolic expression. Here’s an example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08142024diffUPDATEimg3.png' alt='' title='' width='447' height='137'/> </div>\n</p></div>\n<p>There are lots of different ways to display a diff object; many of them one can select interactively with the menu:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/sw08142024diffUPDATEimg4.png' alt='Diff object viewing options' title='Diff object viewing options' width='352' height='450'/></p>\n<p>But the most important thing about diff objects is that they can be used programmatically. And in particular <tt><a href=\"http://reference.wolfram.com/language/ref/DiffApply.html\">DiffApply</a></tt> applies the diffs from a diff object to an existing object, say a notebook. </p>\n<p>What’s the point of this? Well, let’s imagine you’ve made a notebook, and given a copy of it to someone else. Then both you and the person to whom you’ve given the copy make changes. You can create a diff object of the diffs between the original version of the notebook, and the version with your changes. And if the changes the other person made don’t overlap with yours, you can just take your diffs and use <tt><a href=\"http://reference.wolfram.com/language/ref/DiffApply.html\">DiffApply</a></tt> to apply your diffs to their version, thereby getting a “merged notebook” with both sets of changes made.</p>\n<p>But what if your changes might conflict? Well, then you need to use the function <tt><a href=\"http://reference.wolfram.com/language/ref/Diff3.html\">Diff3</a></tt>. <tt><a href=\"http://reference.wolfram.com/language/ref/Diff3.html\">Diff3</a></tt> takes your original notebook and two modified versions, and does a “three-way diff” to give you a diff object in which any conflicts are explicitly identified. (And, yes, three-way diffs are familiar from source control systems in which they provide the back end for making the merging of files as automated as possible.)</p>\n<p>Notebooks are an important use case for <tt><a href=\"http://reference.wolfram.com/language/ref/Diff.html\">Diff</a></tt> and related functions. But they’re not the only one. <tt><a href=\"http://reference.wolfram.com/language/ref/Diff.html\">Diff</a></tt> can perfectly well be applied, for example, just to lists:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg6.png' alt='' title='' width='467' height='102'> </div>\n</p></div>\n<p>There are many ways to display this diff object; here’s a side-by-side view: </p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg7A.png' alt='Side-by-side diff view' title='Side-by-side diff view' width='718' height='245'/></p>\n<p>And here’s a “unified view” reminiscent of how one might display diffs for lines of text in a file:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg8A.png' alt='Unified diff view' title='Unified diff view' width='718' height='259'/></p>\n<p>And, speaking of files, <tt><a href=\"http://reference.wolfram.com/language/ref/Diff.html\">Diff</a></tt>, etc. can immediately be applied to files:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024diffimg9.png' alt='' title='' width='591' height='268'> </div>\n</p></div>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/Diff.html\">Diff</a></tt>, etc. can also be applied to cells, where they can analyze changes in both content and styles or metadata.

Steadily discovering—and inventing—new “lumps of computational work” that make sense to implement as functions or features in the Wolfram Language. The Wolfram Language is of course very much strong enough that one can build essentially any functionality from the primitives that already exist in it. But part of the point of the language is to define the best “elements of computational thought”. And particularly as the language progresses, there’s a continual stream of new opportunities for convenient elements that get exposed. And in Version 14.1 we’ve implemented quite a diverse collection of them.</p>\n<p>Let’s say you want to nestedly compose a function.

Well, you’ll want to make sure you’re doing the best algorithmic things you can (and making the best possible use of Wolfram Language superfunctions, etc.). And perhaps you’ll find it helpful to use things like <tt><a href=\"http://reference.wolfram.com/language/ref/DataStructure.html\">DataStructure</a></tt> constructs. But ultimately if you really want your code to run absolutely as fast as your computer can make it, you’ll probably want to set it up so that it can be compiled using the <a href=\"https://reference.wolfram.com/language/Compile/tutorial/Overview.html\">Wolfram Compiler</a>, directly to LLVM code and then machine code. </p>\n<p>We’ve been developing the Wolfram Compiler for many years, and it’s becoming steadily more capable (and efficient). And for example it’s become increasingly important in our own internal development efforts. In the past, when we wrote critical inner-loop internal code for the Wolfram Language, we did it in C. But in the past few years we’ve almost completely transitioned instead to writing pure Wolfram Language code that we then compile with the Wolfram Compiler. And the result of this has been a dramatically faster and more reliable development pipeline for writing inner-loop code.</p>\n<p>Ultimately what the Wolfram Compiler needs to do is to take the code you write and align it with the low-level capabilities of your computer, figuring out what low-level data types can be used for what, etc. Some of this can be done automatically (using all sorts of fancy symbolic and theorem-proving-like techniques). But some needs to be based on collaboration between the programmer and the compiler. And in Version 14.1 we’re adding several important ways to enhance that collaboration.</p>\n<p>The first thing is that it’s now easy to get access to information the compiler has. For example, here’s the type declaration the compiler has for the built-in function <tt><a href=\"http://reference.wolfram.com/language/ref/Dimensions.html\">Dimensions</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg1.png' alt='' title='' width='654' height='121'> </div>\n</p></div>\n<p>And here’s the source code of the actual implementation the compiler is using for <tt><a href=\"http://reference.wolfram.com/language/ref/Dimensions.html\">Dimensions</a></tt>, calling its intrinsic low-level internal functions like <tt>CopyTo</tt>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg2.png' alt='Compiler source code' title='Compiler source code' width='610' height='366'/></p>\n<p>A function like <tt><a href=\"http://reference.wolfram.com/language/ref/Map.html\">Map</a></tt> has a vastly more complex set of type declarations:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg3.png' alt='' title='' width='662' height='323'> </div>\n</p></div>\n<p>For types themselves, <tt><a href=\"http://reference.wolfram.com/language/ref/CompilerInformation.html\">CompilerInformation</a></tt> lets you see their type hierarchy:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg4.png' alt='' title='' width='378' height='514'> </div>\n</p></div>\n<p>And for data structure types, you can do things like see the fields they contain, and the operations they support:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg5.png' alt='' title='' width='431' height='307'> </div>\n</p></div>\n<p>And, by the way, something new in Version 14.1 is the function <tt><a href=\"http://reference.wolfram.com/language/ref/OperationDeclaration.html\">OperationDeclaration</a></tt> which lets you declare operations to add to a data structure type you’ve defined. </p>\n<p>Once you actually start running the compiler, a convenient new feature in Version 14.1 is a detailed progress monitor that lets you see what the compiler is doing at each step:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg6.png' alt='' title='' width='560' height='201'> </div>\n</p></div>\n<p>As we said, the key to compilation is figuring out how to align your code with the low-level capabilities of your computer. The Wolfram Language can do arbitrary symbolic operations. But many of those don’t align with low-level capabilities of your computer, and can’t meaningfully be compiled. Sometimes those failures to align are the result of sophistication that’s possible only with symbolic operations. But sometimes the failures can be avoided if you “unpack” things a bit. And sometimes the failures are just the result of programming mistakes. And now in Version 14.1 the Wolfram Compiler is starting to be able to annotate your code to show where the misalignments are happening, so you can go through and figure out what to do with them. (It’s something that’s uniquely possible because of the symbolic structure of the Wolfram Language and even more so of Wolfram Notebooks.)</p>\n<p>Here’s a very simple example:</p>\n<p><img src='https://content.wolfram.com/sites/43/2024/07/sw07312024compilerimg7.png' alt='Misalignment error message' title='Misalignment error message' width='604' height='95'/></p>\n<p>In compiled code, <tt><a href=\"http://reference.wolfram.com/language/ref/Sin.html\">Sin</a></tt> expects a numerical argument, so a Boolean argument won’t work.

And, by the way, because it’s completely efficient to call small pieces of compiled code within ordinary Wolfram Language code, it’s common to start by annotating and compiling the “innermost inner loops” in your code, and gradually “working outwards”. </p>\n<p>But, OK, let’s say you’ve successfully compiled a piece of code. Most of the time it’ll handle certain cases, but not others (for example, it might work fine with machine-precision numbers, but not be capable of handling arbitrary precision).

Well, you could always do that by using a web API served from the <a href=\"https://www.wolfram.com/cloud\">Wolfram Cloud</a>. And you could also do it locally by running the Wolfram Engine. But in Version 14.1 there’s something new: a way of integrating a standalone Wolfram Language runtime right into your application. The Wolfram Language runtime is a dynamic library that you link into your program, and then call using a C-based API. How big is the runtime? Well, it depends on what you want to use in the Wolfram Language. Because we now have the technology to prune a runtime to include only capabilities needed for particular Wolfram Language code. And the result is that adding the Wolfram Language will often increase the disk requirements of your application only by a remarkably small amount—like just a few hundred megabytes or even less. And, by the way, you can distribute the Wolfram runtime as an integrated part of an application, with its users not needing their own licenses to run it.</p>\n<p>OK, so how does creating a standalone Wolfram-enabled application actually work? There’s a lot of software engineering (associated with the Wolfram Language runtime, how it’s called, etc.) under the hood. But at the level of the application programmer you only have to deal with our Standalone Applications SDK—whose interface is rather simple. </p>\n<p>As an example, here’s the C code part of a standalone application that uses the Wolfram Language to identify what (human) language a piece of text is in. The program here takes a string of text on its command line, then runs the Wolfram Language <tt><a href=\"http://reference.wolfram.com/language/ref/LanguageIdentify.html\">LanguageIdentify</a></tt> function on it, and then prints a string giving the result: </p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/Ccode1B.png' alt='C code using Wolfram Language' title='C code example using Wolfram Language' width='583' height='563'></p>\n<p>If we ignore issues of pruning, etc. we can compile this program just with (and, yes, the file paths are necessarily a bit long):</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/08/Ccode2C.png' alt='Compiled C program' title='Compiled C program' width='660' height='77'></p>\n<p>Now we can run the resulting executable directly from the command line—and it’ll act just like any other executable, even though inside it’s got all the power of a Wolfram Language runtime:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2024/07/Ccode3C.png' alt='Command-line executable' title='Command-line executable' width='218' height='30'></p>\n<p>If we look at the C program above, it basically begins just by starting the Wolfram Language runtime (using <span class=\"computer-voice\">WLR_SDK_START_RUNTIME()</span>). But then it takes the string <span class=\"computer-voice\">(argv[1])</span> from the command line, embeds it in a Wolfram Language expression <tt><a href=\"http://reference.wolfram.com/language/ref/LanguageIdentify.html\">LanguageIdentify</a></tt><tt>[</tt><em>string</em><tt>]</tt>, evaluates this expression, and extracts a raw string from the result.</p>\n<p>The functions, etc. that are involved here are part of the new Expression API supported by the Wolfram Language runtime dynamic library. The Expression API provides very clean capabilities for building up and taking apart Wolfram Language expressions from C. There are functions like <tt>wlr_</tt><tt>Symbol</tt><tt>(\"</tt><em>string</em><tt>\")</tt> that form symbols, as well as macros like <nobr><tt>wlr_</tt><tt>List</tt><tt>(elem<sub>1</sub>, elem<sub>2</sub>, …)</tt></nobr> and <tt>wlr_</tt><tt>E</tt><tt>(</tt><em>head</em><tt>, arg<sub>1</sub>, arg<sub>2</sub>, …)</tt> that build up lists and general expressions. Then there’s the function <tt>wlr_Eval(expr)</tt> that calls the Wolfram Language evaluator. With functions like <tt>wlr_StringData(expr, &result, …)</tt> you can then extract content from expressions (here the characters in a string) and put it into C data structures. </p>\n<p>How does the Expression API relate to <a href=\"https://www.wolfram.com/wstp/\">WSTP</a>? WSTP (“Wolfram Symbolic Transfer Protocol”) is our protocol for transferring symbolic expressions between processes. The Expression API, on the other hand, operates within a single process, providing the “glue” that connects C code to expressions in the Wolfram Language runtime. </p>\n<p>One example of a real-world use of our new Standalone Applications technology is the LSPServer application that will soon be in full distribution. LSPServer started from a pure (though somewhat lengthy) Wolfram Language paclet that provides Language Server Protocol services for annotating Wolfram Language code in programs like Visual Studio Code. To build the LSPServer standalone application we just wrote a tiny C program that calls the paclet, then compiled this and linked it against our Standalone Applications SDK. Along the way (using tools that we’re planning to soon make available)—and based on the fact that only a small part of the full functionality of the Wolfram Language is needed to support LSPServer—we pruned the Wolfram Language runtime, in the end getting a complete LSPServer application that’s only about 170 MB in size, and that shows no outside signs of having Wolfram Language functionality inside.</p>\n<h2 id=\"and-yet-more\">And Yet More…</h2>\n<p>Is that all? Well, no. There’s more. Like new formatting of <tt><a href=\"http://reference.wolfram.com/language/ref/Root.html\">Root</a></tt> objects (yes, I was frustrated with the old one). Or like a new drag-and-drop-to-answer option for <tt><a href=\"http://reference.wolfram.com/language/ref/QuestionObject.html\">QuestionObject</a></tt> quizzes. Or like all the documentation we’ve added for new types of entities and interpreters. </p>\n<p>In addition, there’s also the continual stream of new data that we’ve curated, or that’s flowed in real time into the <a href=\"https://www.wolfram.com/language/core-areas/knowledgebase/\">Wolfram Knowledgebase</a>. And beyond the core Wolfram Language itself, there’ve also been lots of functions added to the <a href=\"https://resources.wolframcloud.com/FunctionRepository\">Wolfram Function Repository</a>, lots of paclets added to the <a href=\"https://resources.wolframcloud.com/PacletRepository/\">Wolfram Language Paclet Repository</a>, not to mention new entries in the <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/\">Wolfram Neural Net Repository</a>, <a href=\"https://datarepository.wolframcloud.com/\" target=\"_blank\" rel=\"noopener\">Wolfram Data Repository</a>, etc. </p>\n<p>Yes, as always it’s been a lot of work.

We call it measurement. We call it analysis. But in the end it’s about how we take the world as it is, and derive from it the impression of it that we have in our minds.</p>\n<p>We might have thought that we could do science “purely objectively” without any reference to observers or their nature. But what we’ve <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/\">discovered particularly dramatically</a> in our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> is that the nature of us as observers is critical even in determining the most fundamental laws we attribute to the universe.</p>\n<p>But what ultimately does an observer—say like us—do? And how can we make a theoretical framework for it? Much as we have a <a href=\"https://www.wolframscience.com/nks/chap-11--the-notion-of-computation/\">general model for the process of computation</a>—instantiated by something like a <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs#sect-3-4--turing-machines\">Turing machine</a>—we’d like to have a general model for the process of observation: a general “observer theory”.<span id=\"more-55098\"></span></p>\n<p>Central to what we think of as an observer is the notion that the observer will take the raw complexity of the world and extract from it some reduced representation suitable for a finite mind. There might be zillions of photons impinging on our eyes, but all we extract is the arrangement of objects in a visual scene. Or there might be zillions of gas molecules impinging on a piston, yet all we extract is the overall pressure of the gas. </p>\n<p>In the end, we can think of it fundamentally as being about equivalencing. There are immense numbers of different individual configurations for the photons or the gas molecules—that are all treated as equivalent by an observer who’s just picking out the particular features needed for some reduced representation.</p>\n<p>There’s in a sense a certain <a href=\"https://arxiv.org/abs/2301.04690\" target=\"_blank\" rel=\"noopener\">duality between computation and observation</a>. In computation one’s generating new states of a system. In observation, one’s equivalencing together different states.</p>\n<p>That equivalencing must in the end be implemented “underneath” by computation. But in observer theory what we want to do is just characterize the equivalencing that’s achieved. For us as observers it might in practice be all about how our senses work, what our biological or cultural nature is—or what technological devices or structures we’ve built. But what makes a coherent concept of observer theory possible is that there seem to be general, abstract characterizations that capture the essence of different kinds of observers.</p>\n<p>It’s not immediately obvious that anything suitable for a finite mind could ever be extracted from the complexity of the world. And indeed the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> implies that <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a> (and its <a href=\"https://www.wolframinstitute.org/bulletins/2022/06/multicomputational-irreducibility/\" target=\"_blank\" rel=\"noopener\">multicomputational generalization</a>) will be ubiquitous. But within computational irreducibility there must always be slices of computational reducibility. And it’s these slices of reducibility that an observer must try to pick out—and that ultimately make it possible for a finite mind to develop a “useful narrative” about what happens in the world, that allows it to make decisions, predictions, and so on.</p>\n<p>How “special” is what an observer does? At its core it’s just about taking a large set of possible inputs, and returning a much smaller set of possible outputs. And certainly that’s a conceptual idea that’s <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-7--the-notion-of-attractors\">appeared in many fields</a> under many different names: a contractive mapping, reduction to canonical form, a classifier, an acceptor, a forgetful functor, evolving to an attractor, extracting statistics, model fitting, lossy compression, projection, phase transitions, renormalization group transformations, coarse graining and so on. But here we want to think not about what’s “mathematically describable”, but instead about what <a href=\"https://www.wolframscience.com/nks/chap-10--processes-of-perception-and-analysis/\">in general is actually implemented</a>—say by our senses, our measuring devices, or our ways of analyzing things. </p>\n<p>At an ultimate level, everything that happens can be thought of as being captured by <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">the ruliad</a>—the unique object that emerges as the entangled limit of all possible computations. And in a vast generalization of ideas like that our brains—like any other material thing—are made of atoms, so too any observer must be embedded as some kind of structure within the ruliad. But a key concept of observer theory is that it’s possible to make conclusions about an observer’s impression of the world just by knowing about the capabilities—and assumptions—of the observer, without knowing in detail what the observer is “like inside”.</p>\n<p>And so it is, for example, that in our Physics Project we seem to be able to derive—essentially from the structure of the ruliad—the core laws of twentieth-century physics (general relativity, quantum mechanics and the Second Law) just on the basis of two features of us as observers: that we’re computationally bounded, and that we believe we’re persistent in time (even though “underneath” we’re made of different atoms of space at every successive moment). And we can expect that if we were to <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/#what-we-assume-about-ourselves\">include other features of us as observers</a> (for example, that we believe there are persistent objects in the world, or that we believe we have free will) then we’d be able to derive more aspects of the universe as we experience it—or of natural laws we attribute to it.</p>\n<p>But the notion of observers—and observer theory—isn’t <a href=\"https://writings.stephenwolfram.com/2023/12/observer-theory/#observers-of-abstract-worlds\">limited purely to “physical observers”</a>. It applies whenever we try to “get an impression” of something. And so, for example, we can also operate as “mathematical observers”, sampling the ruliad to build up conclusions about mathematical laws. Some features of us as physical observers—like the computational boundedness associated with the finiteness of our minds—inevitably carry over to us as mathematical observers. But other features do not. But the point of observer theory is to provide a general framework in which we can characterize observers—and then see the consequences of those characterizations for the impressions or conclusions observers will form.</p>\n<h2 id=\"the-operation-of-observers\">The Operation of Observers</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-02.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>As humans we have senses like sight, hearing, touch, taste, smell and balance. And through our technology we also have access to a <a href=\"https://www.wolframalpha.com/examples/science-and-technology/units-and-measures\">few thousand other kinds of measurements</a>. So how basically do all these work? </p>\n<p>The vast majority in effect aggregate a large number of small inputs to generate some kind of “average” output—which in the case of measurements is often specified as a (real) number. In a few cases, however, there’s instead a discrete choice between outputs that’s made on the basis of whether the total input exceeds a threshold (think: <a href=\"https://writings.stephenwolfram.com/2021/05/the-problem-of-distributed-consensus/\">distributed consensus</a> schemes, weighing balances, etc.)</p>\n<p>But in all cases what’s fundamentally happening is that lots of different input configurations are all being equivalenced—or, more operationally, the dynamics of the system essentially make all equivalenced states evolve to the same “attractor state”.</p>\n<p>As an example, let’s consider measuring the pressure of a gas. There are various ways to do this. But a very direct one is just to have a piston, and see how much force is exerted by the gas on this piston. So where does this force come from? At the lowest level it’s the result of lots of individual molecules bouncing off the surface of the piston, each transferring a tiny amount of momentum to it. If we looked at the piston at an atomic scale, we’d see it temporarily deform from each molecular impact. But the crucial point is that at a large scale the piston moves together, as a single rigid object—aggregating the effects of all those individual molecular impacts.</p>\n<p>But why does it work this way? Essentially it’s because the intermolecular forces inside the piston are much stronger than the forces associated with molecules in the gas. Or, put more abstractly, there’s more coupling and coherence “inside the observer” than between the observer and what it’s observing.</p>\n<p>We see the same basic pattern over and over again. There’s some form of transduction that couples the individual elements of what’s being observed to the observer. Then “within the observer” there’s something that in essence aggregates all these small effects. Sometimes that aggregation is “directly numerical”, as in the addition of lots of small momentum transfers. But sometimes it’s instead more explicitly like evolution to one attractor rather than another.</p>\n<p>Consider, for example, the case of vision. An array of photons fall on the photoreceptor cells on our retinas, generating electrical signals transmitted through nerve fibers to our brains. Within the brain there’s then effectively a <a href=\"https://reference.wolfram.com/language/ref/ImageIdentify.html\">neural net that evolves to different attractors</a> depending on what one’s looking at. Most of the time a small change in input image won’t affect what attractor one evolves to. But—much like with a weighing balance—there’s an “edge” at which even a small change can lead to a different output.</p>\n<p>One can go through lots of different types of sensory systems and measuring devices. But the basic outline seems to always be the same. First, there’s a coupling between what is being sensed or measured and the thing that’s doing the sensing or measuring. Quite often that coupling involves transducing from one physical form to another—say from light to electricity, or from force to position. Sometimes then the crucial step of equivalencing different detailed inputs is achieved by simple “numerical aggregation”, most often by accumulation of objects (atoms, raindrops, etc.) or physical effects (forces, currents, etc.). But sometimes the equivalencing is instead achieved by a more obviously dynamical process. </p>\n<p>It could amount to simple amplification, in which, say, the presence of a small element of input (say an individual particle) “tips over” some metastable system so that it goes into a certain final state. Or it could be more like a neural net where there’s a more complicated translation defined by hard-to-describe borders between basins of attraction leading to different attractors.</p>\n<p>But, OK, so what’s the endpoint of a process of observation? Ultimately for us humans it’s an impression created in our minds. Of course that gets into lots of slippery philosophical issues. Yes, each of us has an “inner experience” of what’s going on in our mind. But anything else is ultimately an extrapolation. We make the assumption that other human minds also “see what we see”, but we can never “feel it from the inside”. </p>\n<p>We can of course make increasingly detailed measurements—say of neural activity—to see how similar what’s going on is between one brain and another. But as soon as there’s the slightest structural—or situational—difference between the brains, we really can’t say exactly how their “impressions” will compare. </p>\n<p>But for our purposes in constructing a general “observer theory” we’re basically going to make the assumption (or, in effect, “philosophical approximation”) that whenever a system does enough equivalencing, that’s tantamount to it “acting like an observer”, because it can then act as a “front end” that takes the “incoherent complexity of the world” and “collimates it” to the point where a mind will derive a definite impression from it. </p>\n<p>Of course, there’s still a lot of subtlety here. There has to be “just enough equivalencing” and not too much. For example, if all inputs were always equivalenced to the same output, there’d be nothing useful observed. And in the end there’s somehow got to be some kind of match between the compression of input achieved by equivalencing, and the “capacity” of the mind that’s ultimately deriving an impression from it.</p>\n<p>A crucial feature of anything that can reasonably be called a mind is that “something’s got to be going on in there”. It can’t be, for example, that the internal state of the system is fixed. There has to be some internal dynamics—some computational process that we can identify as the ongoing operation of the mind. </p>\n<p>At an informational level we might say that there has to be more information processing going on inside than there is flow of information from the outside. Or, in other words, if we’re going to be meaningful “observers like us” we can’t just be bombarded by input we don’t process; we have to have some capability to “think about what we’re seeing”. </p>\n<p>All of this comes back to the idea that a crucial feature of us as observers is that we are computationally bounded. We do computation; that’s why we can have an “inner sense of things going on”. But the amount of computation we do is tiny compared to the computation going on in the world around us. Our experience represents a heavily filtered version of “what’s happening outside”. And the essence of “being an observer like us” is that we’re effectively doing lots of equivalencing to get to that filtered version.</p>\n<p>But can we imagine a future in which we “expand our minds”? Or perhaps encounter some alien intelligence with a fundamentally “less constrained mind”? Well, at some point there’s an issue with this. Because in a sense the idea that we have a coherent existence relies on us having “limited minds”. For without such constraints there wouldn’t be a coherent “self” that we could identify—with coherent inner experience.</p>\n<p>Let’s say we’re shown some system—say in nature—“from the outside”. Can we tell if “there’s an observer in there”? Ultimately not, because in a sense we’d have to be “inside that observer” and be able to experience the impression of the world that it’s getting. But in much the same way as we extrapolate to believing that, say, other human minds are experiencing things like we’re experiencing, so also we can potentially extrapolate to say what we might think of as an observer.</p>\n<p>And the core idea seems to be that an “observer” should be a subsystem whose “internal states” are affected by the rest of the system, but where many “external states” lead to the same internal state—and where there is rich dynamics “within the observer” that in effect operates only on its internal states. Ultimately—following the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a>—both the outside and the inside of the “observer subsystem” can be expected to be equivalent in the computations they’re performing. But the point is that the coupling from outside the subsystem to inside effectively “coarse grains” what’s outside, so that the “inner computation” is operating on a much-reduced set of elements.</p>\n<p>Why should any such “observer subsystems” exist? Presumably at some level it’s inevitable from the presence of pockets of computational reducibility within arbitrary computationally irreducible systems. But more important for us is that our very existence—and the possibility of our coherent inner experience—depends on us “operating as observers”. And—almost as a “self-fulfilling prophecy”—our behavior tends to perpetuate our ability to successfully do this. For example, we can think of us as choosing to put ourselves in situations and environments where we can “predict what’s going to happen” well enough to “survive as observers”. (At a mundane practical level we might do this by not living in places subject to unpredictable natural forces—or by doing things like building ourselves structures that shelter us from those forces.)</p>\n<p>We’ve talked about observers operating by <a href=\"https://www.wolframscience.com/nks/chap-10--processes-of-perception-and-analysis#sect-10-5--data-compression\">compressing the complexities </a>of the world to “inner impressions” suitable for finite minds. And in typical situations that we describe as perception and measurement, the main way this happens is by fairly direct equivalencing of different states. But in a sense there’s a higher-level story that relies on formalization—and in essence computation—and that’s what we usually call “analysis”. </p>\n<p>Let’s say we have some intricate structure—perhaps some nested, fractal pattern. A direct rendering of all the pixels in this pattern ultimately won’t be something well suited for a “finite mind”. But if we gave rules—or a program—for generating the pattern we’d have a much more succinct representation of it.</p>\n<p>But now there’s a problem with computational irreducibility. Yes, the rules determine the pattern. But to get from these rules to the actual pattern can require an irreducible amount of computation. And to “reverse engineer the pattern” to find the rules can require even more computation. </p>\n<p>Yes, there are particular cases—like repetitive and simple nested patterns—where there’s enough immediate computational reducibility that a computationally bounded system (or observer) can fairly easily “do the analysis” and “get the compression”. But in general it’s hard. And indeed in a sense it’s the whole mission of science to pick away at the problem, and try to find more ways to “reduce the complexities of the world” to “human-level narratives”. </p>\n<p>Computational irreducibility limits the extent to which this can be successful. But the inevitable existence of pockets of reducibility even within computational irreducibility guarantees that progress can always in principle be made. As we invent more kinds of measuring devices we can extend our domain as observers. And the same is true when we invent more methods of analysis, or identify more principles in science.</p>\n<p>But the overall picture remains the same: what’s crucial to “being an observer” is equivalencing many “states of the world”, either through perceiving or measuring only specific aspects of them, or through identifying “simplified narratives” that capture them. (In effect, perception and measurement tend to do “lossy compression”; analysis is more about “lossless compression” where the equivalencing is effectively not between possible inputs but between possible generative rules.)</p>\n<h2 id=\"how-observers-construct-their-perceived-reality\">How Observers Construct Their Perceived Reality</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-03.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>Our view of the world is ultimately determined by what we observe of it. We take what’s “out there in the world” and in effect “construct our perceived reality” by our operation as observers. Or, in other words, insofar as we have a narrative about “what’s going on in the world”, that’s something that comes from our operation as observers. </p>\n<p>And in fact from our Physics Project we’re led to an extreme version of this—in which what’s “out there in the world” is just the whole ruliad, and in effect everything specific about our perceived reality must come from how we operate as observers and thus <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#living-in-rulial-space\">how we sample the ruliad</a>.</p>\n<p>But long before we get to this ultimate level of abstraction, there are lots of ways in which our nature as observers “builds” our perceived reality. Think about any material substance—like a fluid. Ultimately it’s made up of lots of individual molecules “doing their thing”. But observers like us aren’t seeing those molecules. Instead, we’re aggregating things to the point where we can just describe the system as a fluid, that operates according to the “narrative” defined by the laws of fluid mechanics.</p>\n<p>But <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">why do things work this way</a>? Ultimately it’s the result of the repeated story of the interplay between underlying computational irreducibility, and the computational boundedness of us as observers. At the lowest level the motion of the molecules is governed by simple rules of mechanics. But the phenomenon of computational irreducibility implies that to work out the detailed consequences of “running these rules” involves an irreducible amount of computational work—which is something that we as computationally bounded observers can’t do. And the result of this is that we’ll end up describing the detailed behavior of the molecules as just “random”. As I’ve <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">discussed at length elsewhere</a>, this is the fundamental origin of the Second Law of thermodynamics. But for our purposes here the important point is that it’s what makes observers like us “construct the reality” of things like fluids. Our computational boundedness as observers makes us unable to trace all the detailed behavior of molecules, and leaves us “content” to describe fluids in terms of the “narrative” defined by the laws of fluid mechanics.</p>\n<p>Our Physics Project implies that it’s the <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#what-is-space\">same kind of story with physical space</a>. For in our Physics Project, space is ultimately “made” of a network of relations (or connections) between discrete “atoms of space”—that’s progressively being updated in what ends up being a computationally irreducible way. But we as computationally bounded observers can’t “decode” all the details of what’s happening, and instead we end up with a simple “aggregate” narrative, that turns out to correspond to continuum space operating according to the laws of general relativity.</p>\n<p>The way both coherent notions of “matter” (or fluids) and spacetime emerge for us as observers can be thought of as a consequence of the equivalencing we do as observers. In both cases, there’s immense and computationally irreducible complexity “underneath”. But we’re ignoring most of that—by effectively treating different detailed behaviors as equivalent—so that in the end we get to a (comparatively) “simple narrative” more suitable for our finite minds. But we should emphasize that what’s “really going on in the system” is something much more complicated; it’s just that we as observers aren’t paying attention to that, so our perceived reality is much simpler.</p>\n<p>OK, but what about quantum mechanics? In a sense that’s an extreme test of our description of how observers work, and the extent to which the operation of observers “constructs their perceived reality”.</p>\n<h2 id=\"the-case-of-quantum-mechanics\">The Case of Quantum Mechanics</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-04.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>In our Physics Project the underlying structure (hypergraph) that represents space and everything in it is progressively being rewritten according to definite rules. But the crucial point is that at any given stage there can be lots of ways this rewriting can happen. And the result is that there’s a <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#the-inevitability-of-quantum-mechanics\">whole tree of possible “states of the universe”</a> that can be generated. So given this, why do we ever think that definite things happen in the universe? Why don’t we just think that there’s an infinite tree of branching histories for the universe?</p>\n<p>Well, it all has to do with our nature as observers, and the equivalencing we do. At an immediate level, we can imagine looking at all those different possible branching paths for the evolution of the universe. And the key point is that even though they come from different paths of history, two states can just be the same. Sometimes it’ll be obvious that they’re same; sometimes one might have to determine, say, whether two hypergraphs are isomorphic. But the point is that to any observer (at least one that isn’t managing to look at arbitrary “implementation details”), the states will inevitably be considered equivalent.</p>\n<p>But now there’s a bigger point. Even though “from the outside” there might be a whole branching and merging <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\">multiway graph of histories</a> for the universe, observers like us can’t trace that. And in fact all we perceive is a single thread of history. Or, said another way, we believe that we have a <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/#the-quantum-observer\">single thread of experience</a>—something closely related to our belief that (despite the changing “underlying elements” from which we are made) we are somehow persistent in time (at least during the span of our existence).</p>\n<p>But operationally, how do we go from all those underlying branches of history to our perceived single thread of history? We can think of the states on different threads of history as being related by what we call a <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/the-concept-of-branchial-graphs/\" target=\"_blank\" rel=\"noopener\">branchial graph</a>, that joins states that have immediate common ancestors. And in the limit of many threads, we can think of these different states as being laid out “branchial space”. (In traditional quantum mechanics terms, this layout defines a “map of quantum entanglements”—with each piece of common ancestry representing an entanglement between states.)</p>\n<p>In physical space—whether we’re looking at molecules in a fluid or atoms of space—we can think of us operating as observers who are physically large enough to span many underlying discrete elements, so that what we end up observing is just some kind of aggregate, averaged result. And it’s very much the same kind of thing in branchial space: we as observers tend to be large enough in branchial space to be spread across an immense number of branches of history, so that what we observe is just aggregate, averaged results across all those branches. </p>\n<p>There’s lots of detailed complexity in what happens on different branches, just like there is in what happens to different molecules, or different atoms of space. And the reason is that there’s inevitably computational irreducibility, or, in this case, more accurately, multicomputational irreducibility. But as computationally bounded observers we just perceive aggregate results that “average out” the “underlying apparent randomness” to give a consistent single thread of experience. </p>\n<p>And effectively this is what happens in the transition from quantum to classical behavior. Even though there are many possible detailed (“quantum”) threads of history that an object can follow, what we perceive corresponds to a single consistent “aggregate” (“classical”) sequence of behavior. </p>\n<p>And this is typically true even at the level of our typical observation of molecules and chemical processes. Yes, there are many possible threads of history for, say, a water molecule. But most of our observations aggregate things to the point where we can talk about a definite shape for the molecule, with definite “chemical bonds”, etc. </p>\n<p>But there is a special situation that actually looms large in typical discussions of quantum mechanics. We can think of it as the result of doing measurements that aren’t “aggregating threads of history to get an average”, but are instead doing something more like a weighing balance, always “tipping” one way or the other. In the language of <a href=\"https://www.wolfram.com/quantum-computation-framework/\">quantum computing</a>, we might say that we’re arranging things to be able to “measure a single qubit”. In terms of the equivalencing of states, we might say that we’re equivalencing lots of underlying states to specific canonical states (like “spin up” and “spin down”).</p>\n<p>Why do we get one outcome rather than another? Ultimately we can think of it as all depending on the details of us as observers. To see this, let’s start from the corresponding question in physical space. We might ask why we observe some particular thing happening. Well, in our Physics Project everything about “what happens” is deterministic. But there’s still the “arbitrariness” of where we are in physical space. We’ll always basically see the same laws of physics, but the particulars of what we’ll observe depend on where we are, say on the surface of the Earth versus in interstellar space, etc.</p>\n<p>Is there a “theory” for “where we are”? In some sense, yes, because we can go back and see why the molecules that make us up landed up in the particular place where they did. But what we can’t have an “external theory” for is just which molecules end up making up “us”, as we experience ourselves “from inside”. In our view of physics and the universe, it’s in some sense the only “ultimately subjective” thing: where our internal experience is “situated”. </p>\n<p>And the point is that basically—even though it’s much less familiar—the same thing is going on at the level of quantum mechanics. Just as we “happen” to be at a certain place in physical space, so we’re at a certain place in branchial space. Looking back we can trace how we got here. But there’s no <em>a priori</em> way to determine “where our particular experience will be situated”. And that means we can’t know what the “local branchial environment” will be—and so, for example, what the outcome of “balance-like” measurements will be. </p>\n<p>Just as in traditional discussions of quantum mechanics, the mechanics of doing the measurement—which we can think of as effectively equivalencing many underlying branches of history—will have an effect on subsequent behavior, and subsequent measurements. </p>\n<p>But let’s say we look just at the level of the underlying multiway graph—or, more specifically, the multiway causal graph that records causal connections between different updating events. Then we can identify a complicated web of interdependence between events that are timelike, spacelike and branchlike separated. And this interdependence seems to correspond precisely to what’s expected from quantum mechanics. </p>\n<p>In other words, even though the multiway graph is completely determined, the arbitrariness of “where the observer is” (particularly in branchial space), combined with the inevitable interdependence of different aspects of the multiway (causal) graph, seems sufficient to reproduce the not-quite-purely-probabilistic features of quantum mechanics.</p>\n<p>In making observations in physical space, it’s common to make a measurement at one place or time, then make another measurement at another place or time, and, for example, see how they’re related. But in actually doing this, the observer will have to move from one place to the other, and persist from one time to another. And in the abstract it’s not obvious that that’s possible. For example, it could be that an observer won’t be able to move without changing—or, in other words, that “<a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/\">pure motion</a>” won’t be possible for an observer. But in effect this is something we as observers assume about ourselves. And indeed, as I’ve <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/#observers-and-their-physics\">discussed elsewhere</a>, this is a crucial part of why we perceive spacetime to operate according to the laws of physics we know.</p>\n<p>But what about in branchial space? We have much less intuition for this than for physical space. But we still effectively believe that <a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/#motion-beyond-physical-space-the-branchial-case\">pure motion is possible for us as observers in branchial space</a>. It could be—like an observer in physical space, say, near a spacetime singularity—that an observer would get “shredded” when trying to “move” in branchial space. But our belief is that typically nothing like that happens. At some level being at different locations in branchial space presumably corresponds to picking different bases for our quantum states, or effectively to defining our experiments differently. And somehow our belief in the possibility of pure motion in branchial space seems related to our belief in the possibility of making arbitrary sequences choices in sets of experiments we do. </p>\n<h2 id=\"observers-of-abstract-worlds\">Observers of Abstract Worlds</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-05.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>We might have thought that the only thing ultimately “out there” for us to observe would be our physical universe. But actually there are important situations where we’re essentially operating not as observers of our familiar physical universe, but instead of what amount to abstract universes. And what we’ll see is that the ideas of observer theory seem to apply there too—except that now what we’re picking out and reducing to “internal impressions” are features not of the physical world but of abstract worlds.</p>\n<p>Our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> in a sense brings ideas about the physical and abstract worlds closer—and the <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">concept of the ruliad</a> ultimately leads to a deep unification between them. For what we now imagine is that the physical universe as we perceive it is just the result of the particular kind of sampling of the ruliad made by us as certain kinds of observers. And the point is that we as observers can make other kinds of samplings, leading to what we can describe as abstract universes. And one particularly prominent example of this is <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/\">mathematics, or rather, metamathematics</a>.</p>\n<p>Imagine starting from all possible axioms for mathematics, then constructing the network of all possible theorems that can be derived from them. We can consider this as forming a kind of “<a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#metamathematical-space\">metamathematical universe</a>”. And the particular mathematics that some mathematician might study we can then think of as the result of a “mathematical observer” observing that metamathematical universe. </p>\n<p>There are both close analogies and differences between this and the experience of a physical observer in the physical universe. Both ultimately correspond to samplings of the ruliad, but somewhat different ones.</p>\n<p>In our Physics Project we imagine that physical space and everything in it is ultimately made up of discrete elements that we identify as “atoms of space”. But in the ruliad in general we can think of everything being made up of “pure atoms of existence” that we call emes. In the particular case of physics we interpret these emes as atoms of space. But in metamathematics we can think of emes as corresponding to (“subaxiomatic”) elements of symbolic structures—from which things like axioms or theorems can be constructed. </p>\n<p>A central feature of our interaction with the ruliad for physics is that observers like us don’t track the detailed behavior of all the various atoms of space. Instead, we equivalence things to the point where we get descriptions that are reduced enough to “fit in our minds”. And something similar is going on in mathematics.</p>\n<p>We don’t track all the individual <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#going-below-axiomatic-mathematics\">subaxiomatic emes</a>—or usually in practice even the details of fully formalized axioms and theorems. Instead, mathematics typically operates at a much higher and “more human” level, dealing not with questions like how real numbers can be built from emes—or even axioms—but rather with what can be deduced about the properties of mathematical objects like real numbers. In a physics analogy to the behavior of a gas, typical human mathematics operates not at the “molecular” level of individual emes (or even axioms) but rather at the “fluid dynamics” level of “human-accessible” mathematical concepts.</p>\n<p>In effect, therefore, a mathematician is operating as an observer who equivalences many detailed configurations—ultimately of emes—in order to form higher-level mathematical constructs suitable for our computationally bounded minds. And while at the outset one might have imagined that anything in the ruliad could serve as a “possible mathematics”, the point is that observers like us can only sample the ruliad in particular ways—leading to only particular possible forms for “human-accessible” mathematics.</p>\n<p>It’s a very similar story to the one we’ve encountered many times in thinking about physics. In studying gases, for example, we could imagine all sorts of theories based on tracking detailed molecular motions. But for observers like us—with our computational boundedness—we inevitably end up with things like the <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">Second Law of thermodynamics</a>, and the laws of fluid mechanics. And in mathematics the main thing we end up with is “higher-level mathematics”—mathematics that we can do directly in terms of typical textbook concepts, rather than constantly having to “drill down” to the level of axioms, or emes. </p>\n<p>In physics we’re usually particularly concerned with issues like predicting how things will evolve through time. In mathematics it’s more about <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#time-timelessness-and-entailment-fabrics\">accumulating what can be considered true</a>. And indeed we can think of an idealized mathematician as going through the ruliad and collecting in their minds a “bag” of theorems (or axioms) that they “consider to be true”. And given such a collection, they can essentially follow the “entailment paths” defined by computations in the ruliad to find more theorems to “add to their bag”. (And, yes, if they put in a false theorem then—because a false premise in the standard setup of logic implies everything—they’ll end up with an “<a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#the-notion-of-truth\">infinite explosion of theorems</a>”, that won’t fit in a finite mind.)</p>\n<p>In observing the physical universe, we talk about our different possible senses (like vision, hearing, etc.) or different kinds of measuring devices. In observing the metamathematical universe the analogy is basically different possible kinds of theories or abstractions—say, algebraic vs. geometrical vs. topological vs. categorical, etc. (with new approaches being like new kinds of measuring devices).</p>\n<p>Particularly when we think in terms of the ruliad we can expect a certain kind of <a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/#the-physicalized-laws-of-mathematics\">ultimate unity in the metamathematical universe</a>—but different theories and different abstractions will pick up different aspects of it, just as vision and hearing pick up different aspects of the physical universe. But in a sense observer theory gives us a global way to talk about this, and to characterize what kinds of observations observers like us can make—whether of the physical universe or the metamathematical one.</p>\n<p>In physics we’ve then seen in our Physics Project how this allows us to find general laws that describe our perception of the physical world—and that turn out to reproduce the core known laws of physics. In mathematics we’re not as familiar with the concept of general laws, though the very fact that higher-level mathematics is possible is presumably in essence such a law, and perhaps the kinds of regularities seen in areas like category theory are others—as are the inevitable dualities we expect to be able to identify between different fields of mathematics. All these laws ultimately rely on the structure of the ruliad. But the crucial point is that they’re not talking about the “raw ruliad”; instead they’re talking about just certain samplings of the ruliad that can be done by observers like us, and that lead to certain kinds of “internal impressions” in terms of which these laws can be stated.</p>\n<p>Mathematics represents a certain kind of abstract setup that’s been studied in a particularly detailed way over the centuries. But it’s not the only kind of “abstract setup” we can imagine. And indeed there’s even a much more familiar one: the use of concepts—and words—in human thinking and language. </p>\n<p>We might imagine that at some time in the distant past our forebears could signify, say, rocks only by pointing at individual ones. But then there emerged the general notion of “rock”, captured by a word for “rock”. And once again this is a story of observers and equivalences. When we look at a rock, it presumably produces all sorts of detailed patterns of neuron firings in our brains, different for each particular rock. But somehow—presumably essentially through evolution to an attractor in the neural net in our brains—we equivalence all these patterns to extract our “inner impression” of the “concept of a rock”.</p>\n<p>In the typical tradition of quantitative science we tend to be interested in doing measurements that lead to things like numerical results. But in representing the world using language we tend to be interested instead in creating symbolic structures that involve collections of discrete words embedded in a grammatical framework. Such linguistic descriptions don’t capture every detail; in a typical observer kind of way they broadly equivalence many things—and in a sense reduce the complexity of the world to a description in terms of a limited number of discrete words and linguistic forms. </p>\n<p>Within any given person’s brain there’ll be “thoughts” defined by patterns of neuron firings. And the crucial role of language is to provide a way to robustly “package up” those thoughts, and for example represent them with discrete words, so they can be communicated to another person—and unpacked in that person’s brain to produce neuron firings that reproduce what amount to those same thoughts. </p>\n<p>When we’re dealing with something like a numerical measurement we might imagine that it could have some kind of absolute interpretation. But words are much more obviously an “arbitrary basis” for communication. We could pick a different specific word (say from a different human language) but still “communicate the same thing”. All that’s required is that everyone who’s using the word agrees on its meaning. And presumably that normally happens because of shared “social” history between people who use a given word. </p>\n<p>It’s worth pointing out that for this to work there has to be a certain separation of scales. The collective impression of the meaning of a word may change over time, but that change has to be slow compared to the rate at which the word is used in actual communication. In effect, the meaning of a word—as we humans might understand it—emerges from the aggregation of many individual uses. </p>\n<p>In the abstract, there might not be any reason to think that there’d be a way to “understand words consistently”. But it’s a story very much like what we’ve encountered in both physics and mathematics. Even though there are lots of complicated individual details “underneath”, we as observers manage to pick out features that are “simple enough for us to understand”. In the case of molecules in a gas that might be the overall pressure of the gas. And in the case of words it’s a <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/#linguistics\">stable notion of “meaning”</a>. </p>\n<p>Put another way, the possibility of language is another example of observer theory at work. Inside our brains there are all sorts of complicated neuron firings. But somehow these can be “packaged up” into things like words that form “human-level narratives”. </p>\n<p>There’s a certain complicated feedback loop between the world as we experience it and the words we use to describe it. We invent words for things that we commonly encounter (“chair”, “table”, …). Yet once we have a word for something we’re more able to form thoughts about it, or communicate about it. And that in turn makes us more likely to put instances of it in our environment. In other words, we tend to build our environment so that the way we have of making narratives about it works well—or, in effect, so our inner description of it can be as simple as possible, and it can be as predictable to us as possible.</p>\n<p>We can view our experience of physics and of mathematics as being the result of us acting as physical observers and mathematical observers. Now we’re viewing our experience of the “conceptual universe” as being the result of us acting as “conceptual observers”. But what’s crucial is that in all these cases, we have the same intrinsic features as observers: computational boundedness and a belief in persistence. The computational boundedness is what makes us equivalence things to the point where we can have symbolic descriptions of the world, for example in terms of words. And the belief in persistence is what lets those words have persistent meanings. </p>\n<p>And actually these ideas extend beyond just language—to paradigms, and general ways of thinking about things. When we define a word we’re in effect defining an abstraction for a class of things. And paradigms are somehow a generalization of this: ways of taking lots of specifics and coming up with a uniform framework for them. And when we do this, we’re in effect making a classic observer theory move—and equivalencing lots of different things to produce an “internal impression” that’s “simple enough” to fit in our finite minds. </p>\n<h2 id=\"in-the-end-its-all-just-the-ruliad\">In the End It’s All Just the Ruliad</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-06.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>Our tendency as observers is always to believe that we can separate our “inner experience” from what’s going on in the “outside world”. But in the end everything is just part of the ruliad. And at the level of the ruliad we as observers are ultimately “made of the same stuff” as everything else. </p>\n<p>But can we imagine that we can point at one part of the ruliad and say “that’s an observer”, and at another part and say “that’s not”? At least to some extent the answer is presumably yes—at least if we restrict ourselves to “observers like us”. But it’s a somewhat subtle—and seemingly circular—story. </p>\n<p>For example, one core feature of observers like us is that we have a certain persistence, or at least we believe we have a certain persistence. But, inevitably, at the level of the “raw ruliad”, we’re continually being made from different atoms of existence, i.e. different emes. So in what sense are we persistent? Well, the point is that an observer can equivalence those successive patterns of emes, so that what they observe is persistent. And, yes, this is at least on the face of it circular. And ultimately to identify what parts of the ruliad might be “persistent enough to be observers”, we’ll have to ground this circularity in some kind of further assumption.</p>\n<p>What about the computational boundedness of observers like us, which forces us to do lots of equivalencing? At some level that equivalencing must be implemented by lots of different states evolving to the same states. But once again there’s circularity, because even to define what we mean by “the same states” (“Are isomorphic graphs the same?”, etc.) we have to be imagining certain equivalencing. </p>\n<p>So how do we break out of the circularity? The key is presumably the presence of additional features that define “observers like us”. And one important class of such features has to do with scale. </p>\n<p>We’re neither tiny nor huge. We involve enough emes that consistent averages can emerge. Yet we don’t involve so many emes that we span anything but an absolutely tiny part of the whole ruliad. </p>\n<p>And actually a lot of our experience is determined by “our size as observers”. We’re large enough that certain equivalencing is inevitable. Yet we’re small enough that we can reasonably think of there being many choices for “where we are”. </p>\n<p>The overall structure of the ruliad is a <a href=\"https://writings.stephenwolfram.com/2021/04/why-does-the-universe-exist-some-perspectives-from-our-physics-project/\">matter of formal necessity</a>; there’s only one possible way for it to be. But there’s contingency in our character as observers. And for example in a sense there’s a fundamental constant of nature as we perceive it, which is our extent in the ruliad, say measured in emes (and appropriately projected into physical space, branchial space, etc.).</p>\n<p>And the fact that this extent is small compared to the whole ruliad means that there are “many possible observers”—who we can think of as existing at different positions in the ruliad. And those different observers will look at the ruliad from different “points of view”, and thus develop different “internal impressions” of “perceived reality”. </p>\n<p>But a crucial fact central to our Physics Project is that there are certain aspects of that perceived reality that are inevitable for observers like us—and that correspond to core laws of physics. But when it gets to more specific questions (“What does the night sky look like from where you are?”, etc.) different observers will inevitably have different versions of perceived reality.</p>\n<p>So is there a way to translate from one observer to another? Essentially that’s a <a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/\">story of motion</a>. What happens when an observer at one place in the ruliad “moves” to another place? Inevitably, the observer will be “made of different emes” if it’s at a different place. But will it somehow still “be the same”? Well, that’s a subtle question, that depends both on the background structure of the ruliad, and the nature of the observer. </p>\n<p>If the ruliad is “too wild” (think: spacetime near a singularity) then the observer will inevitably be “shredded” as it “moves”. But computational irreducibility implies a certain overall regularity to most of the ruliad, making “pure motion” at least conceivable. But to achieve “pure motion” the observer still has to be “made of” something that is somehow robust—essentially some “lump of computational reducibility” that can “predictably survive” the underlying background of computational irreducibility. </p>\n<p>In spacetime we can identify such “lumps” with things like black holes, and particles like electrons, photons, etc. (and, yes, in our models there’s probably considerable commonality between black holes and particles). It’s not yet clear quite what the analog is in branchial space, though a very simple example might involve persistence of qubits. And in rulial space, one kind of analog is the very notion of concepts. For in effect concepts (as represented for example by words) are the analog of particles in rulial space: they are the robust structures that can move across rulial space and “maintain their identity”, carrying “the same thoughts” to different minds. </p>\n<p>So what does all this mean for what can constitute an observer in the ruliad? Observers in effect leverage computational reducibility to extract simplified features that can “fit in finite minds”. But observers themselves must also embody computational reducibility in order to maintain their own persistence and the persistence of the features they extract. Or in other words, observers must in a sense always correspond to “patches of regularity” in the ruliad. </p>\n<p>But can any patch of regularity in the ruliad be thought of as an observer? Probably not usefully so. Because another feature of observers like us is that we are connected in some kind of collective “social” framework. Not only do we individually form internal impressions in our minds, but we also communicate these impressions. And indeed without such communication we wouldn’t, for example, be able to set up things like coherent languages with which to describe things. </p>\n<h2 id=\"what-we-assume-about-ourselves\">What We Assume about Ourselves</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-07.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>A key implication of our Physics Project and the concept of the ruliad is that we perceive the universe to be the way we do because we are the way we are as observers. And the most fundamental aspect of observers like us is that we’re doing lots of equivalencing to reduce the “complexity of the world” to “internal impressions” that “fit into our minds”. But just what kinds of equivalencing are we actually doing? At some level a lot of that is defined by the things we believe—or assume—about ourselves and the way we interact with the world. </p>\n<p>A very central assumption we make is that we’re somehow “stable observers” of a changing “outside world”. Of course, at some level we’re actually not “stable” at all: we’re built up from emes whose configuration is changing all the time. But our belief in our own stability—and, in effect, our belief in our “persistence in time”—makes us equivalence those configurations. And having done that equivalencing we perceive the universe to operate in a certain way, that turns out to align with the laws of physics we know.</p>\n<p>But actually there’s more than just our assumption of persistence in time. For example, we also have an assumption of persistence in space: we assume that—at least on reasonably short timescales—we’re consistently “observing the universe from the same place”, and not, say, “continually darting around”. The network that represents space is continually changing “around us”. But we equivalence things so that we can assume that—in a first approximation—we are “staying in the same place”. </p>\n<p>Of course, we don’t believe that we have to stay in exactly the same place all the time; we believe we’re able to move. And here we make what amounts to another “assumption of stability”: we assume that <a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/\">pure motion is possible</a> for us as observers. In other words, we assume that we can “go to different places” and still be “the same us”, with the same properties as observers. </p>\n<p>At the level of the “raw ruliad” it’s not at all obvious that such assumptions can be consistently made. But as we discussed above, the fact that for observers like us they can (at least to a good approximation) is a reflection of certain properties of us as observers—in particular of our physical scale, being large in terms of atoms of space but small in terms of the whole universe. </p>\n<p>Related to our assumption about motion is our assumption that “space exists”—or that we can treat space as something coherent. Underneath, there’s all sorts of complicated dynamics of changing patterns of emes. But on the timescales at which we experience things we can equivalence these patterns to allow us to think of space as having a “coherent structure”. And, once again, the fact that we can do this is a consequence of physical scales associated with us as observers. In particular, the speed of light is “fast enough” that it brings information to us from the local region around us in much less time than it takes our brain to process it. And this means that we can equivalence all the different ways in which different pieces of information reach us, and we can consistently just talk about the state of a region of space at a given time.</p>\n<p>Part of our assumption that we’re “persistent in time” is that our thread of experience is—at least locally—continuous, with no breaks. Yes, we’re born and we die—and we also sleep. But we assume that at least on scales relevant for our ongoing perception of the world, we experience time as something continuous.</p>\n<p>More than that, we assume that we have just a single thread of experience. Or, in other words, that there’s always just “one us” going through time. Of course, even at the level of neurons in our brains all sorts of activity goes on in parallel. But somehow in our normal psychological state we seem to concentrate everything so that our “inner experience” follows just one “thread of history”, on which we can operate in a computationally bounded way, and form definite memories and have definite sequences of thoughts. </p>\n<p>We’re not as familiar with branchial space as with physical space. But presumably our “fundamental assumption of stability” extends there as well. And when combined with our basic computational boundedness it then becomes inevitable that (as we discussed above) we’ll conflate different “quantum paths of history” to give us as observers a definite “classical thread of inner experience”. </p>\n<p>Beyond “stability”, another very important assumption we implicitly make about ourselves is what amounts to an assumption of “independence”. We imagine that we can somehow separate ourselves off from “everything else”. And one aspect of this is that we assume we’re localized—and that most of the ruliad “doesn’t matter to us”, so that we can equivalence all the different states of the “rest of the ruliad”.</p>\n<p>But there’s also another aspect of “independence”: that in effect we can choose to do “whatever we want” independent of the rest of the universe. And this means that we assume we can, for example, essentially “do any possible experiment”, make any possible measurement—or “go anywhere we want” in physical or branchial space, or indeed rulial space. We assume that we effectively have “free will” about these things—determined only by our “inner choices”, and independent of the state of the rest of the universe. </p>\n<p>Ultimately, of course, we’re just part of the ruliad, and everything we do is determined by the structure of the ruliad and our history within it. But we can view our “belief of freedom” as a reflection of the fact that we don’t know <em>a priori</em> where we’ll be located in the ruliad—and even if we did, computational irreducibility would <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-7--the-phenomenon-of-free-will\">prevent us from making predictions about what we will do</a>. </p>\n<p>Beyond our assumptions about our own “independence from the rest of the universe”, there’s also the question of independence between different parts of what we observe. And quite central to our way of “parsing the world” is our typical assumption that we can “think about different things separately”. In other words, we assume it’s possible to “factor” what we see happening in the universe into independent parts. </p>\n<p>In science, this manifests itself in the idea that we can do “controlled experiments” in which we study how something behaves in isolation from everything else. It’s not self-evident that this will be possible (and indeed in areas like ethics it might fundamentally not be), but we as observers tend to implicitly assume it. </p>\n<p>And actually, we normally go much further. Because we typically assume that we can describe—and think about—the world “symbolically”. In other words, we assume that we can take all the complexity of the world and represent at least the parts of it that we care about in terms of discrete symbolic concepts, of the kind that appear in human <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">(or computational) language</a>. There’s lots of detail in the world that our limited collection of symbolic concepts doesn’t capture, and effectively “equivalences out”. But the point is that it’s this symbolic description that normally seems to form the backbone of the “inner narrative” we have about the world.</p>\n<p>There’s another implicit assumption that’s being made here, however. And that’s that there’s some kind of stability in the symbolic concepts we’re using. Yes, any particular mind might parse the world using a particular set of symbolic concepts. But we make the implicit assumption that there are other minds out there that work like ours. And this makes us imagine that there can be some form of “objective reality” that’s just “always out there”, to be sampled by whatever mind might happen to come along. </p>\n<p>Not only, therefore, do we assume our own stability as observers; we also assume a certain stability to what we perceive of “everything that’s out there”. Underneath, there’s all the wildness and complexity of the ruliad. But we assume that we can successfully equivalence things to the point where all we perceive is something quite stable—and something that we can describe as ultimately governed by consistent laws. </p>\n<p>It could be that every part of the universe just “does its own thing”, with no overall laws tying everything together. But we make the implicit assumption that, no, the universe—at least as far as we perceive it—is a more organized and consistent place. And indeed it’s that assumption that makes it feasible for us to operate as observers like us at all, and to even imagine that we can usefully reduce the complexity of the world to something that “fits in our finite minds”.</p>\n<h2 id=\"the-cost-of-observation\">The Cost of Observation</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-08.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>What resources does it take for an observer to make an observation? In most of traditional science, observation is at best added as an afterthought, and no account is taken of the process by which it occurs. And indeed, for example, in the traditional formalism of quantum mechanics, while “measurement” can have an effect on a system, it’s still assumed to be an “indivisible act” without any “internal process”.</p>\n<p>But in observer theory, we’re centrally talking about the process of observation. And so it makes sense to try asking questions about the resources involved in this process.</p>\n<p>We might start with our own everyday experience. Something happens out in the world. What resources—and, for example, how much time—does it take us to “form an impression of it”? Let’s say that out in the world a cat either comes into view or it doesn’t. There are signals that come to our brain from our eyes, effectively carrying data on each pixel in our visual field. Then, inside our brain, these signals are <a href=\"https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/\">processed by a succession of layers of neurons</a>, with us in the end concluding either “there’s a cat there”, or “there’s not”. </p>\n<p>And from artificial neural nets we can get a pretty good idea of how this likely works. And the key to it—as we discussed above—is that there’s an attractor. Lots of different detailed configurations of pixels all evolve either to the “cat” or “no cat” final state. The different configurations have been equivalenced, so that only a “final conclusion” survives.</p>\n<p>The story is a bit trickier though. Because “cat” or “no cat” really isn’t the final state of our brain; hopefully it’s not the “last thought we have”. Instead, our brain will continue to “think more thoughts”. So “cat”/”no cat” is at best some kind of intermediate waypoint in our process of thinking; an instantaneous conclusion that we’ll continue to “build on”. </p>\n<p>And indeed when we consider measuring devices (like a piston measuring the pressure of a gas) we similarly usually imagine that they will “come to an instantaneous conclusion”, but “continue operating” and “producing more data”. But how long should we wait for each intermediate conclusion? How long, for example, will it take for the stresses generated by a particular pattern of molecules hitting a piston to “dissipate out”, and for the piston to be “ready to produce more data”?</p>\n<p>There are lots of specific questions of physics here. But if our purpose is to build a formal observer theory, how should we think about such things? There is something of an analogy in the formal theory of computation. An actual computational system—say in the physical world—<a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/#the-world-of-the-s-combinator\">will just “keep computing”</a>. But in formal computation theory it’s useful to talk about <a href=\"https://www.wolframscience.com/nks/p759--undecidability-and-intractability/\">computations that halt</a>, and about functions that can be “evaluated” and give a “definite answer”. So what’s the analog of this in observer theory?</p>\n<p>Instead of general computations, we’re interested in computations that effectively “implement equivalences”. Or, put another way, we want computations that “destroy information”—and that have many incoming states but few outgoing ones. As a practical matter, we can either have the outgoing states explicitly represent whole equivalence classes, or they can just be “canonical representatives”—like in a network where at each step each element takes on whatever the <a href=\"https://writings.stephenwolfram.com/2021/05/the-problem-of-distributed-consensus/\">“majority” or “consensus” value </a>of its neighbors was.</p>\n<p>But however it works, we can still ask questions about what computational resources were involved. How many steps did it take? How many elements were involved? </p>\n<p>And with the idea that observers like us are “computationally bounded”, we expect limitations on these resources. But with this formal setup we can start asking just how far an observer like us can get, say in “coming to a conclusion” about the results of some computationally irreducible process.</p>\n<p>An interesting case arises in <a href=\"https://writings.stephenwolfram.com/2021/04/the-wolfram-physics-project-a-one-year-update/#can-we-finally-understand-quantum-mechanics\">putative quantum computers</a>. In the model implied by our Physics Project, such a “quantum computer” effectively “performs many computations in parallel” on the separate branches of a multiway system representing the various threads of history of the universe. But if the observer tries to “come to a conclusion” about what actually happened, they have to “knit together” all those threads of history, in effect by implementing equivalences between them. </p>\n<p>One could in principle imagine an observer who’d just follow all the quantum branches. But it wouldn’t be an observer like us. Because what seems to be a core feature of observers like us is that we believe we have just a single thread of experience. And to maintain that belief, our “process of observation” must equivalence all the different quantum branches. </p>\n<p>How much “effort” will that be? Well, inevitably if a thread of history branched, our equivalencing has to “undo that branching”. And that suggests that the number of “elementary equivalencings” will have to be at least comparable to the number of “elementary branchings”—making it seem that the “effort of observation” will tend to be at least comparable to reduction of effort associated with parallelism in the “underlying quantum process”.</p>\n<p>In general it’s interesting to compare the “effort of observation” with the “effort of computation”. With our concept of “elementary equivalencings” we have a way to measure both in terms of computational operations. And, yes, both could in principle be implemented by something like a Turing machine, though in practice the equivalencings might be most conveniently modeled by something like string rewriting.</p>\n<p>And indeed one can often go much further, talking not directly in terms of equivalencings, but rather about processes that show attractors. There are different kinds of attractors. Sometimes—as in <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-2--four-classes-of-behavior\">class 1 cellular automata</a>—there are just a limited number of static, global fixed points (say, either all cells black or all cells white). But in other cases—such as <a href=\"https://www.wolframscience.com/nks/p280--the-notion-of-attractors/\">class 3 cellular automata</a>—the number of “output states” may be smaller than the number of “input states” but there may be no computationally simple characterization of them.</p>\n<p>“Observers like us”, though, mostly seem to make use of the fixed points. We try to “symbolicize the world”, taking all the complexities “out there”, and reducing them to “discrete conclusions”, that we might for example describe using the discrete words in a language. </p>\n<p>There’s an immediate subtlety associated with attractors of any kind, though. <a href=\"https://www.wolframscience.com/nks/chap-9--fundamental-physics#sect-9-2--the-notion-of-reversibility\">Typical physics is reversible</a>, in the sense that any process (say two molecules scattering from each other) can run equally well forwards and backwards. But in an attractor one goes from lots of possible initial states to a smaller number of “attractor” final states. And there are <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/#why-the-second-law-works\">two basic ways this can happen</a>, even when there’s underlying reversibility. First, the system one’s studying can be “open”, in the sense that effects can <a href=\"https://www.wolframscience.com/nks/p456--irreversibility-and-the-second-law-of-thermodynamics/\">“radiate” out of the region</a> that one’s studying. And second, the states the system gets into can be “complicated enough” that, say, a computationally bounded observer will inevitably equivalence them. And indeed that’s the main thing that’s happening, for example, when a system “reaches thermodynamic equilibrium”, as described by the Second Law. </p>\n<p>And actually, once again, there’s often a certain circularity. One is trying to determine whether an observer has “finished observing” and “come to a conclusion”. But one needs an observer to make that determination. Can we tell if we’ve finished “forming a thought”? Well, we have to “think about it”—in effect by forming another thought.</p>\n<p>Put another way: imagine we are trying to determine whether a piston has “come to a conclusion” about pressure in a gas. Particularly if there’s microscopic reversibility, the piston and things around it will “continue wiggling around”, and it’ll “take an observer” to determine whether the “heat is dissipated” to the point where one can “read out the result”. </p>\n<p>But how do we break out of what seems like an infinite regress? The point is that whatever mind is ultimately forming the impression that is “the observation” is inevitably the final arbiter. And, yes, this could mean that we’d always have to start discussing all sorts of details about photoreceptors and neurons and so on. But—as we’ve discussed at length—the key point that makes a general observer theory possible is that there are many conclusions that can be drawn for large classes of observers, quite independent of these details.</p>\n<p>But, OK, what happens if we think about the raw ruliad? Now all we have are emes and elementary events updating the configuration of them. And in a sense we’re “<a href=\"https://www.wolframscience.com/metamathematics/going-below-axiomatic-mathematics/\">fishing out of this</a>” pieces that represent observers, and pieces that represent things they’re observing. Can we “assess the cost of observation” here? It really depends on the fundamental scale of what we consider to be observers. And in fact we might even think of our scale as observers (say <a href=\"https://www.wolframscience.com/metamathematics/counting-the-emes-of-mathematics-and-physics/\">measured in emes</a> or elementary events) as defining a “fundamental constant of nature”—at least for the universe as we perceive it. But given this scale, we can for example ask for there to develop “consensus across it”, or at least for “every eme in it to have had time to communicate with every other”. </p>\n<p>In an attempt to formalize the “cost of observation” we’ll inevitably have to make what seem like arbitrary choices, just as we would in setting up a scheme to determine when an ongoing computational process has “generated an answer”. But if we assume a certain boundedness to our choices, we can expect that we’ll be able to draw definite conclusions, and in effect be able to construct an analog of computational complexity theory for processes of observation.</p>\n<h2 id=\"the-future-of-observer-theory\">The Future of Observer Theory</h2>\n<p style=\"display: inline-block;float:left;padding: 0px;margin: 0px;margin-top: 8px;margin-right: 8px;margin-bottom: -4px;\"><img class=\"bookpost\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/12/swOTinset-09.png\" alt=\"\" width=\"68\" height=\"68\" style=\"margin: 0px;padding: 0px;margin-left: 0px;\"></a></p>\n<p>My goal here has been to explore some of the key concepts and principles needed to create a framework that we can call observer theory. But what I’ve done is just the beginning, and there is much still to be done in fleshing out the theory and investigating its implications.</p>\n<p>One important place to start is in making more explicit models of the “mechanics of observation”. At the level of the general theory, it’s all about equivalencing. But how specifically is that equivalencing achieved in particular cases? There are many thousands of kinds of sensors, measuring devices, analysis methods, etc. All of these should be systematically inventoried and classified. And in each case there’s a metamodel to be made, that clarifies just how equivalencing is achieved, and, for example, what separation of physical (or other) scales make it possible.</p>\n<p>Human experience and human minds are the inspiration—and ultimate grounding—for our concept of an observer. And insofar as neural nets trained on what amounts to human experience have emerged as <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">somewhat faithful models for what human minds do</a>, we can expect to use them as a fairly detailed proxy for observers like us. So, for example, we can imagine exploring things like quantum observers by studying multiway generalizations of neural nets. (And this is something that becomes easier if instead of organizing their data into real-number weights we can “atomize” neural nets into purely discrete elements.)</p>\n<p>Such investigations of potentially realistic models provide a useful “practical grounding” for observer theory. But to develop a general observer theory we need a more formal notion of an observer. And there is no doubt a whole abstract framework—perhaps using methods from areas like category theory—that can be developed purely on the basis of our concept of observers being about equivalencing.</p>\n<p>But to understand the connection of observer theory to things like science as done by us humans, we need to tighten up what it means to be an “observer like us”. What exactly are all the general things we “believe about ourselves”? As we discussed above, many we so much take for granted that it’s challenging for us to identify them as actually just “beliefs” that in principle don’t have to be that way. </p>\n<p>But I suspect that the more we can tighten up our definition of “observers like us”, the more we’ll be able to explain why we perceive the world the way we do, and attribute to it the laws and properties we do. Is there some feature of us as observers, for example, that makes us “parse” the physical world as being three-dimensional? We could represent the same data about what’s out there by assigning a one-dimensional (“space-filling”) coordinate to everything. But somehow observers like us don’t do that. And instead, in effect, we “probe the ruliad” by sampling it in what we perceive as 3D slices. (And, yes, the most obvious coarse graining just considers <a href=\"https://www.wolframphysics.org/technical-introduction/limiting-behavior-and-emergent-geometry/the-notion-of-dimension/\" target=\"_blank\" rel=\"noopener\">progressively larger geodesic balls</a>, say in the spatial hypergraphs that appear in our Physics Project—but that’s probably at best just an approximation to the sampling observers like us do.)</p>\n<p>As part of our Physics Project we’ve discovered that the structure of the three main theories of twentieth-century physics (statistical mechanics, general relativity and quantum mechanics) can be derived from properties of the ruliad just by knowing that observers like us are computationally bounded and believe we’re persistent in time. But how might we reach, say, the Standard Model of particle physics—with all its particular values of parameters, etc.? Some may be inevitable, given the underlying structure of our theory. But others, one suspects, are in effect reflections of aspects of us as observers. They are “derivable”, but only given our particular character—or beliefs—as observers. And, yes, presumably things like the “constant of nature” that characterizes “our size in emes” will appear in the laws we attribute to the universe as we perceive it.</p>\n<p>And, by the way, these considerations of “observers like us” extend beyond physical observers. Thus, for example, as we tighten up our characterization of what we’re like as <a href=\"https://www.wolframscience.com/metamathematics/the-underlying-structure-of-mathematics-and-physics/\">mathematical observers</a>, we can expect that this will constrain the “possible <a href=\"https://www.wolframscience.com/metamathematics/the-physicalized-laws-of-mathematics/\">laws of our mathematical universe</a>”. We might have thought that we could “pick whatever axioms we want”, in effect sampling the ruliad to get any mathematics we want. But, presumably, <a href=\"https://www.wolframscience.com/metamathematics/what-axioms-can-there-be-for-human-mathematics/\">observers like us can’t do this</a>—so that questions like “Is the continuum hypothesis true?” can potentially have definite answers for any observers like us, and for any coherent mathematics that we build.</p>\n<p>But in the end, do we really have to consider observers whose characteristics are grounded in human experience? We already reflexively generalize our own personal experiences to those of other humans. But can we go further? We don’t have the internal experience of being a dog, an ant colony, a computer, or an ocean. And typically at best we anthropomorphize such things, trying to reduce the behavior we perceive in them to elements that align with our own human experience. </p>\n<p>But are we as humans just stuck with a particular kind of “internal experience”? The growth of technology—and in particular sensors and measuring devices—has certainly expanded the range of inputs that can be delivered to our brains. And the growth of our collective knowledge about the world has expanded our ways of representing and thinking about things. Right now those are basically our only ways of modifying our detailed “internal experience”. But what if we were to connect directly—and internally—into our brains? </p>\n<p>Presumably, at least at first, we’d need the “neural user interface” to be familiar—and we’d be forced into, for example, concentrating everything into a single thread of experience. But what if we allowed “multiway experience”? Well, of course our brains are already made up of billions of neurons that each do things. But it seems to be a core feature of human experience that we concentrate those things to give a single thread of experience. And that seems to be an essential feature of being an “observer like us”.</p>\n<p>That kind of concentration also happens in a flock of birds, an ant colony—or a human society. In all these cases, each individual organism “does their thing”. But somehow collective “decisions” get made, with many different detailed situations getting equivalenced together to leave only the “final decision”. So that means that from the outside, the system behaves as we would expect of an “observer like us”. Internally, that kind of “observer behavior” is happening “above the experience” of each single individual. But still, at the level of the “hive mind” it’s behavior typical of an observer like us.</p>\n<p>That’s not to say, though, that we can readily imagine what it’s like to be a system like this, or even to be one of its parts. And in the effort to explore observer theory an important direction is to try to imagine ourselves having a different kind of experience than we do. And from <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#alien-views-of-the-ruliad\">“within” that experience</a>, try to see what kind of laws would we attribute, say, to the physical universe.</p>\n<p>In the early twentieth century, particularly in the context of relativity and quantum mechanics, it became clear that being “more realistic” about the observer was crucial in moving forward in science. Things like computational irreducibility—and even more so, our Physics Project—take that another step. </p>\n<p>One used to imagine that science should somehow be “fundamentally objective”, and independent of all aspects of the observer. But what’s become clear is that it’s not. And that the nature of us as observers is actually crucial in determining what science we “experience”. But the crucial point is that there are often powerful conclusions that can be drawn even without knowing all the details of an observer. And that’s a central reason for building a general observer theory—in effect to give an objective way of formally and robustly characterizing what one might consider to be the subjective element in science.</p>\n<h2 id='note' style='font-size:1.2rem'>Note</h2>\n<p style='font-size:90%'>There are no doubt many precursors of varying directness that can be found to the things I discuss here; I have not attempted a <a href=\"https://writings.stephenwolfram.com/category/historical-perspectives/\">serious historical survey</a>.

Mathematics. Logic. These are all ways to formalize the world. And in our century there’s a new and yet more powerful one: computation. </p>\n<p>And for nearly 50 years I’ve had the great privilege of building an ever <a href=\"https://www.stephenwolfram.com/\">taller tower of science and technology</a> based on that idea of computation. And today I want to tell you some of what that’s led to. </p>\n<p>There’s a lot to talk about—so I’m going to go quickly… sometimes with just a sentence summarizing what I’ve written <a href=\"https://www.wolfram-media.com/products/\">a whole book about</a>.<span id=\"more-54525\"></span></p>\n<p>You know, <a href=\"https://www.ted.com/talks/stephen_wolfram_computing_a_theory_of_all_knowledge?language=en\" target=\"_blank\" rel=\"noopener\">I last gave a TED talk thirteen years ago</a>—in February 2010—soon after <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a> launched.</p>\n<p><a href=\"https://www.ted.com/talks/stephen_wolfram_computing_a_theory_of_all_knowledge?language=en\" target=\"_blank\"><img title=\"TED Talk 2010\" src=\"https://content.wolfram.com/sites/43/2023/10/sw-ted-2010-min.jpg\" alt=\"TED Talk 2010\" width=\"620\" height=\"348\" /></a></p>\n<p>And I ended that talk with a question: is computation ultimately what’s underneath everything in our universe?</p>\n<p>I gave myself a decade to find out. And actually it could have needed a century. But in April 2020—just after the decade mark—we were <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/\">thrilled to be able to announce</a> what seems to be the <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">ultimate “machine code” of the universe</a>.</p>\n<p><a href=\"https://www.wolframphysics.org/visual-summary/dark/\"><img title=\"Wolfram Physics Project\" src=\"https://content.wolfram.com/sites/43/2023/10/ted2023-physics-project.png\" alt=\"Wolfram Physics Project\" width=\"620\" height=\"348\" /></a></p>\n<p>And, yes, it’s computational. So computation isn’t just a possible formalization; it’s the ultimate one for our universe.</p>\n<p>It all starts from the idea that <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#what-is-space\">space—like matter—is made of discrete elements</a>. And that the structure of space and everything in it is just defined by the network of relations between these elements—that we might call atoms of space. It’s very elegant—but deeply abstract.</p>\n<p>But here’s a humanized representation:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878695933?h=0202603bb8\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>A version of the very beginning of the universe. And what we’re seeing here is the emergence of space and everything in it by the successive application of very simple computational rules. And, remember, those dots are not atoms in any existing space. They’re atoms <em>of</em> space—that are getting put together to <em>make</em> space. And, yes, if we kept going long enough, we could build our whole universe this way.</p>\n<p>Eons later here’s a chunk of space with two <a href=\"https://arxiv.org/abs/2303.07282\" target=\"_blank\" rel=\"noopener\">little black holes</a>, that eventually merge, radiating ripples of gravitational radiation:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696037?h=91fb6e5261\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>And remember—all this is built from pure computation. But like fluid mechanics emerging from molecules, what emerges here is spacetime—and Einstein’s equations for gravity. Though there are deviations that we just might be able to detect. Like that the <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#the-dimensionality-of-space\">dimensionality of space won’t always be precisely 3</a>.</p>\n<p>And there’s something else. Our computational rules can inevitably be applied in many ways, each defining a different thread of time—a different path of history—that can branch and merge:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696367?h=dc1d3ca2fb\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>But as observers embedded in this universe, we’re branching and merging too. And it turns out that <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#the-inevitability-of-quantum-mechanics\">quantum mechanics emerges</a> as the story of how branching minds perceive a branching universe. </p>\n<p>The little pink lines here show the structure of what we call <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/the-concept-of-branchial-graphs/\" target=\"_blank\" rel=\"noopener\">branchial space</a>—the space of quantum branches. And one of the stunningly beautiful things—at least for a physicist like me—is that the same phenomenon that in <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#general-relativity-and-quantum-mechanics-are-the-same-idea\">physical space gives us gravity, in branchial space gives us quantum mechanics</a>.</p>\n<p>In the history of science so far, I think we can <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\">identify four broad paradigms for making models of the world</a>—that can be distinguished by how they deal with time. </p>\n<p><a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\" rel=\"noopener\"><img title=\"4 paradigms\" src=\"https://content.wolfram.com/sites/43/2023/10/multicomp-table.png\" alt=\"4 paradigms\" width=\"620\" height=\"312\" /></a></p>\n<p>In antiquity—and in plenty of areas of science even today—it’s all about “what things are made of”, and time doesn’t really enter. But in the 1600s came the idea of modeling things with mathematical formulas—in which time enters, but basically just as a coordinate value.</p>\n<p>Then in the 1980s—and this is something in which <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/\">I was deeply involved</a>—came the <a href=\"https://www.wolframscience.com/nksonline/toc.html\">idea of making models by starting with simple computational rules</a> and then just letting them run: </p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696414?h=b8bf5c5e8\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>Can one predict what will happen? No, there’s what I call <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility\">computational irreducibility</a>: in effect the passage of time corresponds to an irreducible computation that we have to run to know how it will turn out.</p>\n<p>But now there’s something even more: in our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> things become <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\">multicomputational</a>, with many threads of time, that can only be knitted together by an observer.</p>\n<p>It’s a new paradigm—that actually seems to unlock things not only in fundamental physics, but also in the <a href=\"https://www.wolframscience.com/metamathematics/\">foundations of mathematics</a> and <a href=\"https://writings.stephenwolfram.com/2023/09/expression-evaluation-and-fundamental-physics/\">computer science</a>, and possibly in areas like <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/#chemistry-molecular-biology\">biology</a> and <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/#economics\">economics</a> too.</p>\n<p>You know, I talked about building up the universe by repeatedly applying a computational rule. But how is that rule picked? Well, actually, it isn’t. Because all possible rules are used. And we’re building up <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">what I call the ruliad</a>: the deeply abstract but unique object that is the entangled limit of all possible computational processes. Here’s a tiny fragment of it shown <a href=\"https://www.wolframphysics.org/bulletins/2020/06/exploring-rulial-space-the-case-of-turing-machines/\" target=\"_blank\" rel=\"noopener\">in terms of Turing machines</a>:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696490?h=288b83f7ab\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>OK, so the ruliad is everything. And <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#observers-like-us\">we as observers are necessarily part of it</a>. In the ruliad as a whole, everything computationally possible can happen. But observers like us can just sample specific slices of the ruliad. </p>\n<p>And there are two crucial facts about us. First, we’re computationally bounded—our minds are limited. And second, we believe we’re persistent in time—even though we’re made of different atoms of space at every moment. </p>\n<p>So then here’s the big result. What <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/\">observers with those characteristics perceive</a> in the ruliad necessarily follows certain laws. And those laws turn out to be precisely the three key theories of 20th-century physics: general relativity, quantum mechanics, and statistical mechanics and the <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/\">Second Law</a>. </p>\n<p>It’s because we’re observers like us that we perceive the laws of physics we do. </p>\n<p>We can think of <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#alien-views-of-the-ruliad\">different minds as being at different places in rulial space</a>. Human minds who think alike are nearby. Animals further away. And further out we get to <a href=\"https://writings.stephenwolfram.com/2022/06/alien-intelligence-and-the-concept-of-technology/\">alien minds</a> where it’s hard to make a translation.</p>\n<p>How can we get intuition for all this? We can use generative AI to take what amounts to an incredibly tiny slice of the ruliad—aligned with images we humans have produced. </p>\n<p>We can think of this as a place in the ruliad described using <a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/\">the concept of a cat in a party hat</a>:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696513?h=0e16c7b964\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>Zooming out, we see what we might call “cat island”. But pretty soon we’re in <a href=\"https://writings.stephenwolfram.com/2023/07/generative-ai-space-and-the-mental-imagery-of-alien-minds/#the-notion-of-interconcept-space\">interconcept space</a>. Occasionally things will look familiar, but mostly we’ll see things we humans don’t have words for. </p>\n<p>In physical space we explore more of the universe by sending out spacecraft. In rulial space we explore more by expanding our concepts and our paradigms. </p>\n<p>We can get a sense of what’s out there by sampling possible rules—doing what I call <a href=\"https://writings.stephenwolfram.com/2021/09/charting-a-course-for-complexity-metamodeling-ruliology-and-more/#the-pure-basic-science-of-ruliology\">ruliology</a>:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696601?h=cf94415092\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>Even with <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/\">incredibly simple rules there’s incredible richness</a>. But the issue is that most of it doesn’t yet connect with things we humans understand or care about. It’s like when we look at the natural world and only gradually realize we can use features of it for technology. Even after everything our civilization has achieved, we’re just at the very, very beginning of exploring rulial space. </p>\n<p>But what about AIs? Just like we can do ruliology, AIs can in principle go out and explore rulial space. But left to their own devices, they’ll mostly be doing things we humans don’t connect with, or care about.</p>\n<p>The big <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">achievements of AI in recent times</a> have been about making systems that are closely aligned with us humans. We train LLMs on billions of webpages so they can produce text that’s typical of what we humans write. And, yes, the fact that this works is <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#what-really-lets-chatgpt-work\">undoubtedly telling us some deep scientific things</a> about the semantic grammar of language—and generalizations of things like logic—that perhaps we should have known centuries ago. </p>\n<p>You know, for much of human history we were kind of like LLMs, figuring things out by matching patterns in our minds. But then came more systematic formalization—and eventually computation. And with that we got a whole other level of power—to create truly new things, and in effect to go wherever we want in the ruliad.</p>\n<p>But the challenge is to do that in a way that connects with what we humans—and our AIs—understand. </p>\n<p>And in fact I’ve devoted a large part of my life to building that bridge. It’s all been about <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">creating a language for expressing ourselves computationally</a>: a language for computational thinking.</p>\n<p>The goal is to formalize what we know about the world—in computational terms. To have computational ways to represent cities and chemicals and movies and formulas—and our knowledge about them.</p>\n<p>It’s been a vast undertaking—that’s <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">spanned more than four decades of my life</a>. It’s something very unique and different. But I’m happy to report that in what has been <a href=\"https://www.wolfram.com/mathematica/\">Mathematica</a> and is now the <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> I think we have now firmly succeeded in creating a truly full-scale computational language.</p>\n<p>In effect, <a href=\"https://reference.wolfram.com/language/\">every one of the functions here</a> can be thought of as formalizing—and encapsulating in computational terms—some facet of the intellectual achievements of our civilization:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696695?h=b4462cc7b2\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>It’s the most concentrated form of intellectual expression I know: finding the essence of everything and coherently expressing it in the design of our computational language. For me personally it’s been an amazing journey, year after year building the tower of ideas and technology that’s needed—and nowadays <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\">sharing that process with the world on open livestreams</a>. </p>\n<p>A few centuries ago the development of mathematical notation, and what amounts to the “language of mathematics”, gave a systematic way to express math—and made possible algebra, and calculus, and ultimately all of modern mathematical science. And computational language now provides a similar path—letting us ultimately create a “computational X” for all imaginable fields X. </p>\n<p>We’ve seen the growth of computer science—CS. But computational language opens up something ultimately much bigger and broader: CX. For 70 years we’ve had programming languages—which are about telling computers in their terms what to do. But computational language is about something intellectually much bigger: it’s about taking everything we can think about and operationalizing it in computational terms.</p>\n<p>You know, I built the Wolfram Language first and foremost because I wanted to use it myself. And now when I use it, I feel like it’s giving me a superpower:</p>\n<div style=\"max-width:620px\">\n<div style=\"position:relative;height:0;padding-bottom:56.25%\"><iframe src=\"https://player.vimeo.com/video/878696815?h=6dc97bbf86\" width=\"620\" height=\"348\" style=\"position:absolute;left:0;top:0;width:100%;height:100%\" frameborder=\"0\" scrolling=\"no\" allowfullscreen></iframe></div>\n</div>\n<p><span></p>\n<p>I just have to imagine something in computational terms and then the language almost magically lets me bring it into reality, see its consequences and then build on them. And, yes, that’s the superpower that’s let me do things like our Physics Project.</p>\n<p>And over the past 35 years it’s been my great privilege to share this superpower with many other people—and by doing so to have enabled such an incredible number of advances across so many fields. It’s a wonderful thing to see people—researchers, CEOs, <a href=\"https://www.wolframcloud.com/obj/microsites/summer-research-high-school/projects.html\">kids</a>—using our language to fluently <a href=\"https://writings.stephenwolfram.com/2016/09/how-to-teach-computational-thinking/\">think in computational terms</a>, crispening up their own thinking and then in effect automatically calling in computational superpowers.</p>\n<p>And now it’s not just people who can do that. AIs can use our computational language as a tool too. Yes, to get their facts straight, but even more importantly, to compute new facts. There are already some <a href=\"https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/\">integrations of our technology into LLMs</a>—and there’s a lot more you’ll be seeing soon. And, you know, when it comes to building new things, a <a href=\"https://writings.stephenwolfram.com/2023/06/introducing-chat-notebooks-integrating-llms-into-the-notebook-paradigm/\">very powerful emerging workflow</a> is basically to start by telling the LLM roughly what you want, then have it try to express that in precise Wolfram Language. Then—and this is a critical feature of our computational language compared to a programming language—you as a human can “read the code”. And if it does what you want, you can use it as a dependable component to build on. </p>\n<p>OK, but let’s say we use more and more AI—and more and more computation. What’s the world going to be like? From the Industrial Revolution on, we’ve been used to doing engineering where we can in effect “see how the gears mesh” to “understand” how things work. But computational irreducibility now shows that won’t always be possible. We won’t always be able to make a simple human—or, say, mathematical—narrative to explain or predict what a system will do. </p>\n<p>And, yes, this is science in effect eating itself from the inside. From all the successes of mathematical science we’ve come to believe that somehow—if only we could find them—there’d be formulas to predict everything. But now computational irreducibility shows that isn’t true. And that in effect to find out what a system will do, we have to go through the same irreducible computational steps as the system itself.</p>\n<p>Yes, it’s a weakness of science. But it’s also why the passage of time is significant—and meaningful. We can’t just jump ahead and get the answer; we have to “live the steps”. </p>\n<p>It’s going to be a great societal dilemma of the future. If we let our AIs achieve their full computational potential, they’ll have lots of computational irreducibility, and we won’t be able to predict what they’ll do. But if we put constraints on them to make them predictable, we’ll limit what they can do for us. </p>\n<p>So what will it feel like if our world is full of computational irreducibility? Well, it’s really nothing new—because that’s the story with much of nature. And what’s happened there is that we’ve found ways to operate within nature—even though nature can still surprise us.</p>\n<p>And so it will be with the AIs. We might <a href=\"https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/\">give them a constitution</a>, but there will always be consequences we can’t predict. Of course, even figuring out societally what we want from the AIs is hard. Maybe we need a promptocracy where people write prompts instead of just voting. But basically every control-the-outcome scheme seems full of both political philosophy and computational irreducibility gotchas. </p>\n<p>You know, if we look at the whole arc of human history, the one thing that’s systematically changed is that more and more gets automated. And LLMs just gave us a dramatic and unexpected example of that. So does that mean that <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/\">in the end we humans will have nothing to do</a>? Well, if you look at history, what seems to happen is that when one thing gets automated away, it opens up lots of new things to do. And as economies develop, the <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/#afterword-looking-at-some-actual-data\">pie chart of occupations</a> seems to get more and more fragmented.</p>\n<p>And now we’re back to the ruliad. Because at a foundational level what’s happening is that automation is opening up more directions to go in the ruliad. And there’s no abstract way to choose between them. It’s just a question of what we humans want—and it requires humans “doing work” to define that.</p>\n<p>A society of AIs untethered by human input would effectively go off and explore the whole ruliad. But most of what they’d do would seem to us random and pointless. Much like now most of nature doesn’t seem like it’s “achieving a purpose”. </p>\n<p>One used to imagine that to build things that are useful to us, we’d have to do it step by step. But AI and the whole phenomenon of computation tell us that really what we need is more just to define what we want. Then computation, AI, automation can make it happen. </p>\n<p>And, yes, I think the key to defining in a clear way what we want is computational language. You know—even after 35 years—for many people the Wolfram Language is still an artifact from the future. If your job is to program it seems like a cheat: how come you can do in an hour what would usually take a week? But it can also be daunting, because having dashed off that one thing, you now have to conceptualize the next thing. Of course, it’s great for CEOs and CTOs and intellectual leaders who are ready to race onto the next thing. And indeed it’s impressively popular in that set. </p>\n<p>In a sense, what’s happening is that Wolfram Language shifts from concentrating on mechanics to concentrating on conceptualization. And the key to that conceptualization is broad computational thinking. So <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/#preparing-for-an-ai-world\">how can one learn to do that</a>? It’s not really a story of CS. It’s really a story of CX. And as a kind of education, it’s more like liberal arts than STEM. It’s part of a trend that when you automate technical execution, what becomes important is not figuring out how to do things—but what to do. And that’s more a story of broad knowledge and general thinking than any kind of narrow specialization.</p>\n<p>You know, there’s an unexpected human-centeredness to all of this. We might have thought that with the advance of science and technology, the particulars of us humans would become ever less relevant. But we’ve discovered that that’s not true. And that in fact everything—even our physics—depends on how we humans happen to have sampled the ruliad.</p>\n<p>Before our Physics Project we didn’t know if our universe really was computational. But now it’s pretty clear that it is. And from that we’re inexorably led to the ruliad—with all its vastness, so hugely greater than all the physical space in our universe. </p>\n<p>So where will we go in the ruliad? Computational language is what lets us chart our path. It lets us humans define our goals and our journeys. And what’s amazing is that all the power and depth of what’s out there in the ruliad is accessible to everyone. One just has to learn to harness those computational superpowers. Which <a href=\"https://www.wolfram.com/language/\">starts here</a>.

For what Doug was fundamentally trying to do over the forty years he spent developing his CYC system was to use the framework of logic—in more or less the same form that Aristotle and Leibniz had it—to capture what happens in the world. It was a noble effort and an impressive example of long-term intellectual tenacity. And while I never managed to actually use CYC myself, I consider it a magnificent experiment—that if nothing else ultimately served to demonstrate the importance of building frameworks beyond logic alone in usefully representing and reasoning about the world.<span id=\"more-53645\"></span></p>\n<p>Doug Lenat started working on artificial intelligence at a time when nobody really knew what might be possible—or even easy—to do. Was AI (whatever that might mean) just a clever algorithm—or a new type of computer—away? Or was it all just an “engineering problem” that simply required pulling together a bigger and better “expert system”? There was all sorts of mystery—and quite a lot of hocus pocus—around AI. Did the demo one was seeing actually prove something, or was it really just a trivial (if perhaps unwitting) cheat? </p>\n<p>I first met Doug Lenat at the beginning of the 1980s. I had just <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">developed my SMP (“Symbolic Manipulation Program”) system</a>, that was the forerunner of <a href=\"https://www.wolfram.com/mathematica/scrapbook/\">Mathematica</a> and the modern <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>. And I had been quite exposed to commercial efforts to “do AI” (and indeed our VCs had even pushed my first company to take on the dubious name “Inference Corporation”, complete with a “=>” logo). And I have to say that when I first met Doug I was quite dismissive. He told me he had a program (that he called <a href=\"https://en.wikipedia.org/wiki/Automated_Mathematician\" target=\"_blank\" rel=\"noopener\">“AM” for “Automated Mathematician”</a>, and that had been the subject of his Stanford CS PhD thesis) that could discover—and in fact had discovered—nontrivial mathematical theorems. </p>\n<p>“What theorems?” I asked. “What did you put in? What did you get out?” I suppose to many people the concept of searching for theorems would have seemed like something remarkable, and immediately exciting. But not only had I myself just built a system for systematically representing mathematics in computational form, I had also been <a href=\"https://www.wolframscience.com/nks/chap-1--the-foundations-for-a-new-kind-of-science#sect-1-4--the-personal-story-of-the-science-in-this-book\">enumerating large collections of simple programs</a> like cellular automata. I poked at what Doug said he’d done, and came away unconvinced. Right around the same time I happened to be visiting a leading university AI group, who told me they had a system for translating stories from Spanish into English. “Can I try it?” I asked, suspending for a moment my feeling that this sounded like science fiction. “I don’t really know Spanish”, I said, “Can I start with just a few words?” “No”, they said, “the system works only with stories.” “How long does a story have to be?” I asked. “Actually it has to be a particular kind of story”, they said. “What kind?” I asked. There were a few more iterations, but eventually it came out: the “system” translated one particular story from Spanish into English! I’m not sure if my response included an expletive, but I wondered what kind of science, technology, or anything else this was supposed to be. And when Doug told me about his “Automated Mathematician”, this was the kind of thing I was afraid I was going to find.</p>\n<p>Years later, I might say, I think there’s something AM could have been trying to do that’s valid, and interesting, if not obviously possible. Given a particular axiom system it’s easy to mechanically generate infinite collections of “true theorems”—that in effect <a href=\"https://www.wolframscience.com/metamathematics/\">fill metamathematical space</a>. But now the question is: which of these theorems will <a href=\"https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/\">human mathematicians find “interesting”</a>? It’s not clear how much of the answer has to do with the “social history of mathematics”, and how much is more about “abstract principles”. I’ve been <a href=\"https://www.wolframscience.com/metamathematics/empirical-metamathematics/\">studying this quite a bit in recent years</a> (not least because I think it could be useful in practice)—and have some rather deep conclusions about its relation to the nature of mathematics. But I now do wonder to what extent Doug’s work from all those years ago might (or might not) contain heuristics that would be worth trying to pursue even now.</p>\n<h2 id=\"cyc\">CYC</h2>\n<p>I ran into Doug quite a few times in the early to mid-1980s, both around a company called <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">Thinking Machines</a> (to which I was a consultant) and at various events that somehow touched on AI. There was a fairly small and somewhat fragmented AI community in those days, with the academic part in the US concentrated around MIT, Stanford and CMU. I had the impression that Doug was never quite at the center of that community, but was somehow nevertheless a “notable member”, who—particularly with his work being connected to math—was seen as “doing upscale things” around AI. </p>\n<p>In 1984 I wrote an article for a special issue of <em>Scientific American</em> on “computer software” (yes, software was trendy then). My article was entitled “<a href=\"https://content.wolfram.com/sw-publications/2020/07/computer-software-science-mathematics.pdf\" target=\"_blank\" rel=\"noopener\">Computer Software in Science and Mathematics</a>”, and the very next article was by Doug, entitled “Computer Software for Intelligent Systems”. The summary at the top of my article read: “Computation offers a new means of describing and investigating scientific and mathematical systems. Simulation by computer may be the only way to predict how certain complicated systems evolve.” And the summary for Doug’s article read: “The key to intelligent problem solving lies in reducing the random search for solutions. To do so intelligent computer programs must tap the same underlying ‘sources of power’ as human beings”. And I suppose in many ways both of us spent most of our next four decades essentially trying to fill out the promise of these summaries.</p>\n<p>A key point in Doug’s article—with which I wholeheartedly agree—is that to create something one can usefully identify as “AI”, it’s essential to somehow have lots of knowledge of the world built in. But how should that be done? How should the knowledge be encoded? And how should it be used?</p>\n<p>Doug’s article in <em>Scientific American</em> illustrated his basic idea:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/09/SA-v2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/SA-v2.png' alt='Click to enlarge' title='Click to enlarge' width='616' height='569'/></a></p>\n<p>Encode knowledge about the world in the form of statements of logic. Then find ways to piece together these statements to derive conclusions. It was, in a sense, a very classic approach to formalizing the world—and one that would at least in concept be familiar to Aristotle and <a href=\"https://writings.stephenwolfram.com/2013/05/dropping-in-on-gottfried-leibniz/\">Leibniz</a>. Of course it was now using computers—both as a way to store the logical statements, and as a way to find inferences from them.</p>\n<p>At first, I think Doug felt the main problem was how to “search for correct inferences”. Given a whole collection of logical statements, he was asking how these could be knitted together to answer some particular question. In essence it was just like <a href=\"https://www.wolframscience.com/metamathematics/relations-to-automated-theorem-proving/\">mathematical theorem proving</a>: how could one knit together axioms to make a proof of a particular theorem? And especially with the computers and algorithms of the time, this seemed like a daunting problem in almost any realistic case. </p>\n<p>But then how did humans ever manage to do it? What Doug imagined was that the critical element was heuristics: strategies for guessing how one might “jump ahead” and not have to do the kind of painstaking searches that systematic methods seemed to imply would be needed. Doug developed a system he called <a href=\"https://en.wikipedia.org/wiki/Eurisko\" target=\"_blank\" rel=\"noopener\">EURISKO</a> that implemented a range of heuristics—that Doug expected could be used not only for math, but basically for anything, or at least anything where human-like thinking was effective. And, yes, EURISKO included not only heuristics, but also at least some kinds of heuristics for making new heuristics, etc.</p>\n<p>But OK, so Doug imagined that EURISKO could be used to “reason about” anything. So if it had the kind of knowledge humans do, then—Doug believed—it should be able to reason just like humans. In other words, it should be able to deliver some kind of “genuine artificial intelligence” capable of matching human thinking. </p>\n<p>There were all sorts of specific domains of knowledge to consider. But Doug particularly wanted to push in what seemed like the most broadly impactful direction—and tackle the problem of commonsense knowledge and commonsense reasoning. And so it was that Doug began what would become a lifelong project to encode as much knowledge as possible in the form of statements of logic.</p>\n<p>In 1984 Doug’s project—now named CYC—became a flagship part of <a href=\"https://en.wikipedia.org/wiki/Microelectronics_and_Computer_Technology_Corporation\" target=\"_blank\" rel=\"noopener\">MCC (Microelectronics and Computer Technology Corporation)</a> in Austin, TX—an industry-government consortium that had just been created to counter the perceived threat from the <a href=\"https://en.wikipedia.org/wiki/Fifth_Generation_Computer_Systems\" target=\"_blank\" rel=\"noopener\">Japanese “Fifth Generation Computer Project”</a>, that had shocked the US research establishment by putting immense resources into “solving AI” (and was actually emphasizing many of the same underlying rule-based techniques as Doug). And at MCC Doug had the resources to hire scores of people to embark on what was expected to be a few thousand person-years of effort.</p>\n<p>I didn’t hear much about CYC for quite a while, though shortly after Mathematica was released in 1988 <a href=\"https://writings.stephenwolfram.com/2016/01/farewell-marvin-minsky-19272016/\">Marvin Minsky</a> mused to me about how it seemed like we were doing for math-like knowledge what CYC was hoping to do for commonsense knowledge. I think Marvin wasn’t convinced that Doug had the technical parts of CYC right (and, yes, they weren’t using Marvin’s theories as much as they might). But in those years Marvin seemed to feel that CYC was one of the few AI projects going on that actually made any sense. And indeed in my archives I find a rather charming email from Marvin in 1992, attaching a draft of a <a href=\"https://www.amazon.com/Turing-Option-Questar-Science-Fiction/dp/0446364967\" target=\"_blank\" rel=\"noopener\">science fiction novel (entitled </a><em><a href=\"https://www.amazon.com/Turing-Option-Questar-Science-Fiction/dp/0446364967\" target=\"_blank\" rel=\"noopener\">The Turing Option</a></em><a href=\"https://www.amazon.com/Turing-Option-Questar-Science-Fiction/dp/0446364967\" target=\"_blank\" rel=\"noopener\">)</a> that he was writing with <a href=\"https://www.wolframalpha.com/input?i=harry+harrison\">Harry Harrison</a>, which contained mention of CYC:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\"><em>June 19, 2024</em></p></blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">When Brian and Ben reached the lab, the computer was running<br />\nbut the tree-robot was folded and motionless. “Robin,<br />\nactivate.”</p></blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">…</p></blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">“Robin will have to use different concepts of progress for<br />\ndifferent kinds of problems.

But mostly AI as a whole was in the doldrums, and almost nobody seemed to be taking it seriously. Sometimes I would hear murmurs about CYC, mostly from government and military contacts. Among academics, Doug would occasionally come up, but rather cruelly he was most notable for his name being used for a <a href=\"https://en.wikipedia.org/wiki/List_of_humorous_units_of_measurement\" target=\"_blank\" rel=\"noopener\">unit of “bogosity”</a>—the lenat—of which it was said that “Like the farad it is considered far too large a unit for practical use, so bogosity is usually expressed in microlenats”.</p>\n<h2 id=\"doug-meets-wolframalpha\">Doug Meets Wolfram|Alpha</h2>\n<p>Many years passed. I certainly hadn’t forgotten Doug, or CYC. And a few times people suggested connecting CYC in some way to our technology. But nothing ever happened. Then in the spring of 2009 we were nearing the first release of <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>, and it seemed like I finally had something that I might meaningfully be able to talk to Doug about. </p>\n<p>I sent a rather tentative email:<br />\n<body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> something you might find interesting…</div>\n<div><span>Date:</span> Thu, 05 Mar 2009 11:15:04 -0500</div>\n<div><span>From:</span> Stephen Wolfram</div>\n<div><span>To:</span> Doug Lenat</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nWe’re in the final stages of a rather large project that I think relates to<br />\nsome of your interests.</p>\n<p>I just made a small blog post about it: </p>\n<p style=\"Source Sans Pro',Arial,sans-serif;\"\n\n<pre>http://blog.wolfram.com/2009/03/05/wolframalpha-is-coming/</pre>\n</p>\n<p>I’d be pleased to give you a webconference demo if you’re interested.</p>\n<p>I hope you’ve been well all these years.</p>\n<p>— Stephen</p></div>\n</div>\n<p></body></html></p>\n<p>Doug quickly responded:<br />\n<body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Re: something you might find interesting…</div>\n<div><span>Date:</span> Thu, 5 Mar 2009 13:23:31 -0600</div>\n<div><span>From:</span> Doug Lenat</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nHi, Stephen.</p>\n<p>You have become a master of understatement! This certainly<br />\ndoes relate to the 1000 person-years we’ve spent building Cyc’s ontology,<br />\nknowledge base, and inference engines, over the last 25 years. I’d very<br />\nmuch like to see a webconference demo, so we identify the opportunities for<br />\nsynergy.</p>\n<p>Regards<br />\nDoug</p></div>\n</div>\n<p></body></html></p>\n<p>It was definitely a “you’re on my turf” kind of response. And I wasn’t sure what to expect from Doug. But a few days later we had a long call with Doug and some of the senior members of what was now the Cycorp team. And Doug did something that deeply impressed me. Rather than for example nitpicking that Wolfram|Alpha was “not AI” he basically just said “We’ve been trying to do something like this for years, and now you’ve succeeded”. It was a great—and even inspirational—show of intellectual integrity. And whatever I might think of CYC and Doug’s other work (and I’d never formed a terribly clear opinion), this for me put Doug firmly in the category of people to respect.</p>\n<p>Doug wrote a blog post entitled “<a href=\"https://www.dataversity.net/doug-lenat-i-was-positively-impressed-with-wolfram-alpha/\" target=\"_blank\" rel=\"noopener\">I was positively impressed with Wolfram Alpha</a>”, and immediately started inviting us to various AI and industry-pooh-bah events to which he was connected. </p>\n<p>Doug seemed genuinely pleased that we had made such progress in something so close to his longtime objectives. I talked to him about the comparison between our approaches. He was just working with “pure human-like reasoning”, I said, like one would have had to do in the Middle Ages. But, I said, “In a sense we cheated”. Because we used all the things that got invented in modern times in science and math and so on. If he wanted to work out how some mechanical system would behave, he would have to reason through it: “If you push this down, that pulls up, then this rolls”, etc. But with what we’re doing, we just have to turn everything into math (or something like it), then systematically solve it using equations and so on. </p>\n<p>And there was something else too: we weren’t trying to use just logic to represent the world, we were using the full power and richness of computation. In talking about the Solar System, we didn’t just say that “Mars is a planet contained in the Solar System”; we had an algorithm for computing its detailed motion, and so on. </p>\n<p>Doug and CYC had also emphasized the scraps of knowledge that seem to appear in our “common sense”. But we were interested in systematic, computable knowledge. We didn’t just want a few scattered “common facts” about animals. We wanted systematic tables of <a href=\"https://reference.wolfram.com/language/ref/entity/Species.html\">properties of millions of species</a>. And we had very general computational ways to represent things: not just words or tags for things, but systematic ways to capture computational structures, whether they were entities, graphs, formulas, images, time series, or geometrical forms, or whatever. </p>\n<p>I think Doug viewed CYC as some kind of formalized idealization of how he imagined human minds work: providing a framework into which a large collection of (fairly undifferentiated) knowledge about the world could be “poured”. At some level it was a very “pure AI” concept: set up a generic brain-like thing, then “it’ll just do the rest”. But Doug still felt that the thing had to operate according to logic, and that what was fed into it also had to consist of knowledge packaged up in the form of logic.</p>\n<p>But while Doug’s starting points were AI and logic, mine were something different—in effect computation writ large. I always viewed logic as something not terribly special: a particular formal system that described certain kinds of things, but didn’t have any great generality. To me the truly general concept was computation. And that’s what I’ve always used as my foundation. And it’s what’s now led to the modern Wolfram Language, with its character as a <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">full-scale computational language</a>. </p>\n<p>There is a principled foundation. But it’s not logic. It’s something much more general, and structural: arbitrary symbolic expressions and transformations of them. And I’ve spent much of the past forty years building up coherent computational representations of the whole range of concepts and constructs that we encounter in the world and in our thinking about it. The goal is to have a language—in effect, a notation—that can represent things in a precise, computational way. But then to actually have the built-in capability to compute with that representation. Not to figure out how to string together logical statements, but rather to do whatever computation might need to be done to get an answer. </p>\n<p>But beyond their technical visions and architectures, there is a certain parallelism between CYC and the Wolfram Language. Both have been huge projects. Both have been in development for more than forty years. And both have been led by a single person all that time. Yes, the Wolfram Language is certainly the larger of the two. But in the spectrum of technical projects, CYC is still a highly exceptional example of longevity and persistence of vision—and a truly impressive achievement.</p>\n<h2 id=\"later-years\">Later Years</h2>\n<p>After Wolfram|Alpha came on the scene I started interacting more with Doug, not least because I often <a href=\"https://writings.stephenwolfram.com/2013/03/talking-about-the-computational-future-at-sxsw-2013/\">came to the SXSW conference in Austin</a>, and would usually make a point of reaching out to Doug when I did. Could CYC use Wolfram|Alpha and the Wolfram Language? Could we somehow usefully connect our technology to CYC?</p>\n<p>When I talked to Doug he tended to downplay the commonsense aspects of CYC, instead talking about defense, intelligence analysis, healthcare, etc. applications. He’d enthusiastically tell me about particular kinds of knowledge that had been put into CYC. But time and time again I’d have to tell him that actually we already had systematic data and algorithms in those areas. Often I felt a bit bad about it. It was as if he’d been painstakingly planting crops one by one, and we’d come through with a giant industrial machine. </p>\n<p>In 2010 we made a big “<a href=\"https://www.wolframalpha.com/docs/timeline\">Timeline of Systematic Data and the Development of Computable Knowledge</a>” poster—and CYC was on it as one of the six entries that began in the 1980s (alongside, for example, the web). Doug and I continued to talk about somehow working together, but nothing ever happened. One problem was the asymmetry: Doug could play with Wolfram|Alpha and Wolfram Language any time. But I’d never once actually been able to try CYC. Several times Doug had promised API keys, but none had ever materialized.</p>\n<p>Eventually Doug said to me: “Look, I’m worried you’re going to think it’s bogus”. And particularly knowing Doug’s history with alleged “bogosity” I tried to assure him my goal wasn’t to judge. Or, as I put it in a 2014 email: “Please don’t worry that we’ll think it’s ‘bogus’. I’m interested in finding the good stuff in what you’ve done, not criticizing its flaws.”</p>\n<p>But when I was at SXSW the next year Doug had something else he wanted to show me. It was a math education game. And Doug seemed incredibly excited about its videogame setup, complete with 3D spacecraft scenery. My son Christopher was there and politely asked if this was the default Unity scenery. I kept on saying, “Doug, I’ve seen videogames before; show me the AI!” But Doug didn’t seem interested in that anymore, eventually saying that the game wasn’t using CYC—though did still (somewhat) use “rule-based AI”.</p>\n<p>I’d already been talking to Doug, though, about what I saw as being an obvious, powerful application of CYC in the context of Wolfram|Alpha: solving math word problems. Given a problem, say, in the form of equations, we could solve pretty much anything thrown at us. But with a word problem like “If Mary has 7 marbles and 3 fall down a drain, how many does she now have?” we didn’t stand a chance. Because to solve this requires commonsense knowledge of the world, which isn’t what Wolfram|Alpha is about. But it is what CYC is supposed to be about. Sadly, though, despite many reminders, we never got to try this out. (And, yes, we built various simple linguistic templates for this kind of thing into Wolfram|Alpha, and <a href=\"https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/#cracking-some-old-chestnuts\">now there are LLMs</a>.)</p>\n<p>Independent of anything else, it was impressive that Doug had kept CYC and Cycorp running all those years. But when I saw him in 2015 he was enthusiastically telling me about what I told him seemed to me to be a too-good-to-be-true deal he was making around CYC. A little later there was a strange attempt to sell us the technology of CYC, and I don’t think our teams interacted again after that. </p>\n<p>I personally continued to interact with Doug, though. I sent him things I <a href=\"https://writings.stephenwolfram.com/2014/08/computational-knowledge-and-the-future-of-pure-mathematics/\">wrote about the formalization of math</a>. He responded pointing me to <a href=\"https://www.ijcai.org/Proceedings/77-2/Papers/099.pdf\" target=\"_blank\" rel=\"noopener\">things he’d done on AM</a>. On the <a href=\"https://writings.stephenwolfram.com/2019/05/wolframalpha-at-10/\">tenth anniversary of Wolfram|Alpha</a> Doug sent me a nice note, offering that “If you want to team up on, e.g., knocking the Winograd sentence pairs out of the park, let me know.” I have to say I wondered what a “Winograd sentence pair” was. It felt like some kind of challenge from an age of AI long past (apparently it has to do with identifying pronoun reference, which of course has become even more difficult in modern English usage). </p>\n<p>And as I write this today, I realize a mistake I made back in 2016. I had for years been thinking about what I’ve come to call “symbolic discourse language”—an extension of computational language that can represent “everyday discourse”. And—stimulated by blockchain and the idea of computational contracts—I finally <a href=\"https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/\">wrote something about this in 2016</a>, and I now realize that I overlooked sending Doug a link to it. Which is a shame, because maybe it would have finally been the thing that got us to connect our systems.</p>\n<h2 id=\"and-now-there-are-llms\">And Now There Are LLMs</h2>\n<p>Doug was a person who believed in formalism, particularly logic. And I have the impression that he always considered approaches like neural nets not really to have a chance of “solving the problem of AI”. But <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">now we have LLMs</a>. So how do they fit in with things like the ideas of CYC? </p>\n<p>One of the surprises of LLMs is that they often seem, in effect, to use logic, even though there’s nothing in their setup that explicitly involves logic. But (as I’ve <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#semantic-grammar-and-the-power-of-computational-language\">described elsewhere</a>) I’m pretty sure what’s happened is that LLMs have “discovered” logic much as Aristotle did—by looking at lots of examples of statements people make and identifying patterns in them. And in a similar way LLMs have “discovered” lots of commonsense knowledge, and reasoning. They’re just following patterns they’ve seen, but—probably in effect organized into what I’ve called a “<a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#semantic-grammar-and-the-power-of-computational-language\">semantic grammar</a>” that determines “<a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#meaning-space-and-semantic-laws-of-motion\">laws of semantic motion</a>”—that’s enough to often achieve some fairly impressive commonsense-like results. </p>\n<p>I suspect that a great many of the statements that were fed into CYC could now be generated fairly successfully with LLMs. And perhaps one day there’ll be good enough “LLM science” to be able to identify mechanisms behind what LLMs can do in the commonsense arena—and maybe they’ll even look a bit like what’s in CYC, and how it uses logic. But in a sense the very success of LLMs in the commonsense arena strongly suggests that you don’t fundamentally need deep “structured logic” for that. Though, yes, the LLM may be immensely less efficient—and perhaps less reliable—than a direct symbolic approach.</p>\n<p>It’s a very different story, by the way, with computational language and computation. LLMs are through and through based on language and patterns to be found through it. But computation—as it can be accessed through structured computational language—is something very different. It’s about processes that are in a sense thoroughly non-human, and that involve much deeper following of general formal rules, as well as much more structured kinds of data, etc. An LLM might be able to do basic logic, as humans have. But it doesn’t stand a chance on things where humans have had to systematically use formal tools that do serious computation. Insofar as LLMs represent “statistical AI”, CYC represents a certain level of “symbolic AI”. But computational language and computation go much further—to a place where LLMs can’t and shouldn’t follow, and should <a href=\"https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/\">just call them as tools</a>. </p>\n<p>Doug always seemed to have a very optimistic view of the promise of AI. In 2013 he wrote to me:<br />\n<body></p>\n<div class=\"email\">\n<div class=\"emailhead\"></div>\n<div class=\"emailbody\">Of course you are coming at this from the opposite end of the Chunnel than<br />\nwe are, but you’re proceeding, frankly, much more rapidly toward us than we<br />\nare toward you. I probably appreciate the significance of what you’ve<br />\naccomplished more than almost anyone else: when your and our approaches do<br />\nmeet up, the combination will be the existence of real AI on Earth. I<br />\nthink that’s the main motivation in your life, as it is in mine: to live to<br />\nsee real AI, with the obvious sweeping change in all aspects of life when<br />\nthere is (i) cradle-to-grave 24×7 Aristotle mentoring and advising for<br />\nevery human being and, in effect, (ii) a Land of Faerie intelligence<br />\neffectively present [e.g., that one can converse with] in every door, floor<br />\ntile,…every tangible object above a certain microscopic size.) And to<br />\nlive to see and be users ourselves in an era of massively amplified human<br />\nintelligence …</p>\n</div>\n</div>\n<p></body></html></p>\n<p>The last mail I received from Doug was on January 10, 2023—telling me that he thought it was great that I was <a href=\"https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/\">talking about connecting our tech to ChatGPT</a>. He said, though, that he found it “increasingly worrisome that these models train on CONVINCINGNESS rather than CORRECTNESS”, then gave an example of ChatGPT getting a math word problem wrong.<br />\nHis email ended:<br />\n<body></p>\n<div class=\"email\">\n<div class=\"emailhead\"></div>\n<div class=\"emailbody\">Yes, let’s chat again at your convenience… it bothers both of us, I<br />\nbelieve, that our systems aren’t leveraging each other! That just bothers<br />\nme more and more as I get old (not just older).</p>\n</div>\n</div>\n<p></body></html></p>\n<p>Sadly we never did chat again. We now have a team actively working on symbolic discourse language, and just last week I mentioned CYC to them—and lamented that I’d never been able to try it. And then on Friday I heard that Doug had died. A remarkable pioneer of AI who steadfastly pursued his vision over the whole course of his career, and was taken far too soon.</p>\n",

It’s an old and oft-debated question in philosophy. And it now turns out to also be a question that rises to prominence in connection with the <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">concept of the ruliad</a> that’s emerged from our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Wolfram Physics Project</a>.</p>\n<p>I’ve wondered about alien minds for a long time—and tried all sorts of ways to imagine what it might be like to see things from their point of view. But in the past I’ve never really had a way to build my intuition about it. That is, until now. So, what’s changed? It’s AI. Because in AI we finally have an accessible form of alien mind.<span id=\"more-52580\"></span></p>\n<p>We typically go to <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">a lot of trouble to train</a> our AIs to produce results that are like we humans would do. But what if we take a human-aligned AI, and modify it? Well, then we get something that’s in effect an alien AI—an AI aligned not with us humans, but with an alien mind.</p>\n<p>So how can we see what such an alien AI—or alien mind—is “thinking”? A convenient way is to try to capture its “mental imagery”: the image it forms in its “mind’s eye”. Let’s say we use a typical <a href=\"https://reference.wolfram.com/language/ref/ImageSynthesize.html\">generative AI</a> to go from a description in human language—like “a cat in a party hat”—to a generated image:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323img2.png' alt='' title='' width='149' height='149'> </div>\n</p></div>\n<p>It’s exactly the kind of image we’d expect—which isn’t surprising, because it <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/Stable-Diffusion-V1/\">comes from a generative AI</a> that’s trained to “do as we would”. But now let’s imagine taking the neural net that implements this generative AI, and modifying its insides—say by resetting <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#neural-nets\">weights that appear in its neural net</a>.</p>\n<p>By doing this we’re in effect going from a human-aligned neural net to some kind of “alien” one. But this “alien” neural net will still produce some kind of image—because that’s what a neural net like this does. But what will the image be? Well, in effect, it’s showing us the mental imagery of the “alien mind” associated with the modified neural net. </p>\n<p>But what does it actually look like? Well, here’s a sequence obtained by progressively modifying the neural net—in effect making it “progressively more alien”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071223sec1img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec1img3.png' alt='' title='' width='612' height='201'> </div>\n</p></div>\n<p>At the beginning it’s still a very recognizable picture of “a cat in a party hat”. But it soon becomes more and more alien: the mental image in effect diverges further from the human one—until it no longer “looks like a cat”, and in the end looks, at least to us, rather random. </p>\n<p>There are many details of how this works that we’ll be discussing below. But what’s important is that—by studying the effects of changing the neural net—we now have a systematic “experimental” platform for probing at least one kind of “alien mind”. We can think of what we’re doing as a kind of “artificial neuroscience”, probing not actual human brains, but neural net analogs of them.</p>\n<p>And we’ll see many parallels to neuroscience experiments. For example, we’ll often be “knocking out” particular parts of our “neural net brain”, a little like how injuries such as strokes can knock out parts of a human brain. But we know that when a human brain suffers a stroke, this can lead to phenomena like “<a href=\"https://en.wikipedia.org/wiki/Hemispatial_neglect\" target=\"_blank\" rel=\"noopener\">hemispatial neglect</a>”, in which a stroke victim asked to draw a clock will end up drawing just one side of the clock—a little like the pictures of cats “degrade” when parts of the “neural net brain” are knocked out. </p>\n<p>Of course, there are many differences between real brains and artificial neural nets. But most of the core phenomena we’ll observe here seem robust and fundamental enough that we can expect them to span very different kinds of “brains”—human, artificial and alien. And the result is that we can begin to build up intuition about what the worlds of different—and alien—minds can be like. </p>\n<h2 id=\"generating-images-with-ais\">Generating Images with AIs</h2>\n<p>How does an AI manage to create a picture, say of a cat in a party hat? Well, the AI has to be trained on “what makes a reasonable picture”—and how to determine what a picture is of. Then in some sense what the AI does is to start generating “reasonable” pictures at random, in effect continually checking what the picture it’s generating seems to be “of”, and tweaking it to guide it towards being a picture of what one wants.</p>\n<p>So what counts as a “reasonable picture”? If one looks at billions of pictures—say on the web—there are lots of regularities. For example, the pixels aren’t random; nearby ones are usually highly correlated. If there’s a face, it’s usually more or less symmetrical. It’s more common to have blue at the top of a picture, and green at the bottom. And so on. And the important technological point is that it turns out to be possible to use a neural network to capture regularities in images, and to generate random images that exhibit them.</p>\n<p>Here are some examples of “random images” generated in this way:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071223sec2img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec2img1.jpg' alt='' title='' width='624' height='834'> </div>\n</p></div>\n<p>And the idea is that these images—while each is “random” in its specifics—will in general follow the “statistics” of the billions of images from the web on which the neural network has been “trained”. We’ll be talking more about images like these later. But for now suffice it to say that while some may just look like abstract patterns, others seem to contain things like landscapes, human forms, etc. And what’s notable is that none just look like “random arrays of pixels”; they all show some kind of “structure”. And, yes, given that they’ve been trained from pictures on the web, it’s not too surprising that the “structure” sometimes includes things like human forms. </p>\n<p>But, OK, let’s say we specifically want a picture of a cat in a party hat. From all of the almost infinitely large number of possible “well-structured” random images we might generate, how do we get one that’s of a cat in a party hat? Well, a first question is: how would we know if we’ve succeeded? As humans, we could just look and see what our image is of. But it turns out we can also <a href=\"https://reference.wolfram.com/language/ref/ImageIdentify.html\">train a neural net to do this</a> (and, no, it <a href=\"https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/\">doesn’t always get it exactly right</a>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071623sec2rowexportimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec2img3.png' alt='' title='' width='610' height='108'> </div>\n</p></div>\n<p>How is the <a href=\"https://reference.wolfram.com/language/ref/NetTrain.html\">neural net trained</a>? The basic idea is to take billions of images—say from the web—for which corresponding captions have been provided. Then one progressively tweaks the parameters of the neural net to make it reproduce these captions when it’s fed the corresponding images. But the critical point is the <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#neural-nets\">neural net turns out to do more</a>: it also successfully produces “reasonable” captions for images it’s never seen before. What does “reasonable” mean? Operationally, it means captions that are similar to what we humans might assign. And, yes, it’s far from obvious that a computationally constructed neural net will behave at all like us humans, and the fact that it does <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">is presumably telling us</a> fundamental things about how human brains work.</p>\n<p>But for now what’s important is that we can use this captioning capability to progressively guide images we produce towards what we want. Start from “pure randomness”. Then try to “structure the randomness” to make a “reasonable” picture, but at every step see in effect “what the caption would be”. And try to “go in a direction” that “leads towards” a picture with the caption we want. Or, in other words, progressively try to get to a picture that’s of what we want. </p>\n<p>The way this is set up in practice, one starts from an array of random pixels, then iteratively forms the picture one wants:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071223sec2img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec2img5.jpg' alt='' title='' width='612' height='196'> </div>\n</p></div>\n<p>Different initial arrays lead to different final pictures—though if everything works correctly, the final pictures will all be of “what one asked for”, in this case a cat in a party hat (and, yes, there are a few “glitches”):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071623Sec2catshatsimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec2img6.png' alt='' title='' width='618' height='198'> </div>\n</p></div>\n<p>We don’t know how mental images are formed in human brains. But it seems conceivable that the process is not too different. And that in effect as we’re trying to “conjure up a reasonable image”, we’re continually checking if it’s aligned with what we want—so that, for example, if our checking process is impaired we can end up with a different image, as in hemispatial neglect. </p>\n<h2 id=\"the-notion-of-interconcept-space\">The Notion of Interconcept Space</h2>\n<p>That everything can ultimately be represented in terms of digital data is foundational to the whole computational paradigm. But the effectiveness of neural nets relies on the slightly different idea that it’s useful to treat at least many kinds of things as being characterized by arrays of real numbers. In the end one might extract from a neural net that’s giving captions to images the word “cat”. But inside the neural net it’ll operate with arrays of numbers that correspond in some fairly abstract way to the image you’ve given, and the textual caption it’ll finally produce.</p>\n<p>And in general neural nets can typically be thought of as associating “feature vectors” with things—whether those things are images, text, or anything else. But whereas words like “cat” and “dog” are discrete, the <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#the-concept-of-embeddings\">feature vectors associated with them</a> just contain collections of real numbers. And this means that we can think of a whole space of possibilities, with “cat” and “dog” just corresponding to two specific points. </p>\n<p>So what’s out there in that space of possibilities? For the feature vectors we typically deal with in practice <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/CLIP-Multi-domain-Feature-Extractor/\">the space is many-thousand-dimensional</a>. But we can for example look at the (nominally straight) line from the “dog point” to the “cat point” in this space, and even generate sample images of what comes between:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071223sec3Aimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec3Aimg1.png' alt='' title='' width='609' height='196'> </div>\n</p></div>\n<p>And, yes, if we want to, we can keep going “beyond cat”—and pretty soon things start becoming quite weird:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071623sec3catmorphimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec3Aimg2.png' alt='' title='' width='610' height='196'> </div>\n</p></div>\n<p>We can also do things like look at the line from a plane to a cat—and, yes, there’s strange stuff in there (wings <img title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071123rightarrow.png\" alt=\"\" width=\"16\" height=\"10\" /> hat <img title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071123rightarrow.png\" alt=\"\" width=\"16\" height=\"10\" /> ears?):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071223sec3Aimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071223sec3Aimg3.png' alt='' title='' width='619' height='199'> </div>\n</p></div>\n<p>What about elsewhere? For example, what happens “around” our standard “cat in a party hat”? With the <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/CLIP-Multi-domain-Feature-Extractor/\">particular setup we’re using</a>, there’s a 2304-dimensional space of possibilities. But as an example, we look at what we get on a particular 2D plane through the “standard cat” point:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img1A.jpeg' alt='' title='' width='621' height='621'> </div>\n</p></div>\n<p>Our “standard cat” is in the middle.

But relative to the whole space, each island is absolutely tiny—something like perhaps a fraction 2<sup>–2000</sup> ≈ 10<sup>–600</sup> of the volume of the whole space. And between these islands there lie huge expanses of what we might call “interconcept space”. </p>\n<p>What’s out there in interconcept space? It’s full of images that are “statistically reasonable” based on the images we humans have put on the web, etc.—but aren’t of things we humans have come up with words for. It’s as if in developing our civilization—and our human language—we’ve “colonized” only certain small islands in the space of all possible concepts, leaving vast amounts of interconcept space unexplored. </p>\n<p>What’s out there is pretty weird—and sometimes a bit disturbing.

In a sense, words fail us. They’re things on the shores of interconcept space, where human experience has not (yet) taken us, and for which human language has not been developed.</p>\n<p>What if we venture further out into interconcept space—and for example just sample points in the space at random? It’s just like we already saw above: we’ll get images that are somehow “statistically typical” of what we humans have put on the web, etc., and on which our AI was trained. Here are a few more examples:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071623sec3Zimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071623sec3Zimg1.jpg' alt='' title='' width='620' height='828'> </div>\n</p></div>\n<p>And, yes, we can pick out at least two basic classes of images: ones that seem like “pure abstract textures”, and ones that seem “representational”, and remind us of real-world scenes from human experience. There are intermediate cases—like “textures” with structures that seem like they might “represent something”, and “representational-seeming” images where we just can’t place what they might be representing.</p>\n<p>But when we do see recognizable “real-world-inspired” images they’re a curious reflection of the concepts—and general imagery—that we humans find “interesting enough to put on the web”. We’re not dealing here with some kind of “arbitrary interconcept space”; we’re dealing with “human-aligned” interconcept space that’s in a sense anchored to human concepts, but extends between and around them. And, yes, viewed in these terms it becomes quite unsurprising that in the interconcept space we’re sampling, there are so many images that remind us of human forms and common human situations. </p>\n<p>But just what were the images that the AI saw, from which it formed this model of interconcept space? There were a <a href=\"https://laion.ai/blog/laion-5b/\" target=\"_blank\" rel=\"noopener\">few billion of them, “foraged” from the web</a>. Like things on the web in general, it’s a motley collection; here’s a random sample:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071523sec3photogridimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071523sec3photogridimg1.jpg' alt='' title='' width='620' height='394'> </div>\n</p></div>\n<p>Some can be thought of as capturing aspects of “life as it is”, but many are more aspirational, coming from staged and often promotionally oriented photography. And, yes, there are lots of Net-a-Porter-style “clothing-without-heads” images. There are also lots of images of “things”—like food, etc. But somehow when we sample randomly in interconcept space it’s the human forms that most distinctively stand out, conceivably because “things” are not particularly consistent in their structure, but human forms always have a certain consistency of “head-body-arms, etc.” structure.</p>\n<p>It’s notable, though, that even the most real-world-like images we find by randomly sampling interconcept space seem to typically be “painterly” and “artistic” rather than “photorealistic” and “photographic”. It’s a different story close to “concept points”—like on cat island. There more photographic forms are common, though as we go away from the “actual concept point”, there’s a tendency towards either a rather toy-like appearance, or something more like an illustration.</p>\n<p>By the way, even the most “photographic” images the AI generates won’t be anything that comes directly from the training set. Because—as we’ll discuss later—the AI is not set up to directly store images; instead its training process in effect “grinds up” images to extract their “statistical properties”. And while “statistical features” of the original images will show up in what the AI generates, any detailed arrangement of pixels in them is overwhelmingly unlikely to do so.</p>\n<p>But, OK, what happens if we start not at a “describable concept” (like “a cat in a party hat”), but just at a random point in interconcept space?

Many have a certain artistic quality to them—and a feeling that they are some kind of “mindful interpretation” of a perhaps mundane thing in the world, or a simple, essentially mathematical pattern. And to some extent the “mind” involved is a collective version of our human one, reflected in a neural net that has “experienced” some of the many images humans have put on the web, etc. But in some ways the mind is also a more alien one, formed from the computational structure of the neural net, with its particular features, and no doubt in some ways <a href=\"https://www.wolframscience.com/nks/p737--computational-irreducibility/\">computationally irreducible</a> behavior.</p>\n<p>And indeed there are some motifs that show up repeatedly that are presumably reflections of features of the underlying structure of the neural net.

But what might a different kind of mind imagine?</p>\n<p>As a very rough approximation, we can think of just taking the trained “mind” we’ve created, and explicitly modifying it, then seeing what it now “imagines”. Or, more specifically, we can take the neural net we have been using, and start making changes to it, and seeing what effect that has on the images it produces.</p>\n<p>We’ll discuss later the details of how the network is set up, but suffice it to say here that it <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/Stable-Diffusion-V1/\">involves 391 distinct internal modules</a>, involving altogether nearly a billion numerical weights. When the network is trained, those numerical weights are carefully tuned to achieve the results we want. But what if we just change them? We’ll still (normally) get a network that can generate images. But in some sense it’ll be “thinking differently”—so potentially the images will be different. </p>\n<p>So as a very coarse first experiment—reminiscent of many that are done in biology—let’s just “knock out” each successive module in turn, setting all its weights to zero.

But how does this fit into a more general picture of alien minds and what they might be like?</p>\n<p>With the <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">concept of the ruliad</a> we finally have a principled way to <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#alien-views-of-the-ruliad\">talk about alien minds</a>—at least at a theoretical level. And the key point is that any alien mind—or, for that matter, any mind—can be thought of as “observing” or sampling the ruliad from its own particular point of view, or in effect, its own position in rulial space.</p>\n<p>The ruliad is defined to be the entangled limit of all possible computations: a unique object with an inevitable structure. And the idea is that anything—whether one interprets it as a phenomenon or an observer—must be part of the ruliad. The key to our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> is then that “observers like us” have <a href=\"https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/\">certain general characteristics</a>. We are computationally bounded, with “finite minds” and limited sensory input. And we have a certain coherence that comes from our belief in our persistence in time, and our consistent thread of experience. And what we then discover in our Physics Project is the rather remarkable result that from these characteristics and the general properties of the ruliad alone it’s essentially inevitable that we must perceive the universe to exhibit the fundamental physical laws it does, in particular the three big theories of twentieth-century physics: general relativity, quantum mechanics and statistical mechanics. </p>\n<p>But what about more detailed aspects of what we perceive? Well, that will depend on more detailed aspects of us as observers, and of how our minds are set up. And in a sense, each different possible mind can be thought of as existing in a certain place in rulial space. Different human minds are mostly close in rulial space, animal minds further away, and more alien minds still further. But how can we characterize what these minds are “thinking about”, or how these minds “perceive things”?</p>\n<p>From inside our own minds we can form a sense of what we perceive. But we don’t really have good ways to reliably probe what another mind perceives. But what about what another mind imagines? Well, that’s where what we’ve been doing here comes in. Because with generative AI we’ve got a mechanism for exposing the “mental imagery” of an “AI mind”. </p>\n<p>We could consider doing this with words and text, say with an LLM. But for us humans images have a certain fluidity that text does not. Our eyes and brains can perfectly well “see” and absorb images even if we don’t “understand” them. But it’s very difficult for us to absorb text that we don’t “understand”; it usually tends to seem just like a kind of “word soup”. </p>\n<p>But, OK, so we generate “mental imagery” from “minds” that have been “made alien” by various modifications. How come we humans can understand anything such minds make? Well, it’s bit like one person being able to understand the thoughts of another. Their brains—and minds—are built differently. And their “internal view” of things will inevitably be different. But the crucial idea—that’s for example central to language—is that it’s possible to “package up” thoughts into something that can be “transported” to another mind. Whatever some particular internal thought might be, by the time we can express it with words in a language, it’s possible to communicate it to another mind that will “unpack” it into different internal thoughts.</p>\n<p>It’s a nontrivial fact of physics that <a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/\">“pure motion” in physical space is possible</a>; in other words, that an “object” can be moved “without change” from one place in physical space to another. And now, in a sense, we’re asking about <a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/#motion-in-rulial-space\">pure motion in rulial space</a>: can we move something “without change” from one mind at one place in rulial space to another mind at another place? In physical space, things like particles—as well as things like black holes—are the fundamental elements that are imagined to move without change. So what’s now the analog in rulial space? It seems to be concepts—as often, for example, represented by words. </p>\n<p>So what does that mean for our exploration of generative AI “alien minds”? We can ask whether when we move from one potentially alien mind to another concepts are preserved. We don’t have a perfect proxy for this (though we could make a better one by appropriately training neural net classifiers). But as a first approximation this is like asking whether as we “change the mind”—or move in rulial space—we can still recognize the “concept” the mind produces. Or, in other words, if we start with a “mind” that’s generating a cat in a party hat, will we still recognize the concepts of cat or hat in what a “modified mind” produces? </p>\n<p>And what we’ve seen is that sometimes we do, and sometimes we don’t. And for example when we looked at “cat island” we saw a certain boundary beyond which we could no longer recognize “catness” in the image that was produced. And by studying things like cat island (and particularly its analogs when not just the “prompt” but also the underlying neural net is changed) it should be possible to map out how far concepts “extend” across alien minds.</p>\n<p>It’s also possible to think about a kind of inverse question: just what is the <a href=\"https://www.wolframphysics.org/bulletins/2020/06/exploring-rulial-space-the-case-of-turing-machines/#the-emerging-picture-of-rulial-space\" target=\"_blank\" rel=\"noopener\">extent of a mind in rulial space</a>? Or, in other words, what range of points of view, ultimately about the ruliad, can it hold? Will it be “narrow-minded”, able to think only in particular ways, with particular concepts? Or will it be more “broad-minded”, encompassing more ways of thinking, with more concepts?</p>\n<p>In a sense the whole arc of the intellectual development of our civilization can be thought of as corresponding to an expansion in rulial space: with us progressively being able to think in new ways, and about new things. And as we expand in rulial space, we are in effect encompassing more of what we previously would have had to consider the domain of an alien mind.</p>\n<p>When we look at images produced by generative AI away from the specifics of human experience—say in interconcept space, or with modified rules of generation—we may at first be able to make little from them. Like inkblots or arrangements of stars we’ll often find ourselves wanting to say that what we see looks like this or that thing we know.</p>\n<p>But the real question is whether we can devise some way of describing what we see that allows us to build thoughts on what we see, or “reason” about it. And what’s very typical is that we manage to do this when we come up with a general “symbolic description” of what we see, say captured with words in natural language (or, now, <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">computational language</a>). Before we have those words, or that symbolic description, we’ll tend just not to absorb what we see.</p>\n<p>And so, for example, even though <a href=\"https://www.wolframscience.com/nks/p187--substitution-systems-and-fractals/\">nested patterns</a> have always existed in nature, and were even explicitly <a href=\"https://writings.stephenwolfram.com/2018/01/showing-off-to-the-universe-beacons-for-the-afterlife-of-our-civilization/#lessons-from-the-past\">created by mosaic artisans in the early 1200s</a>, they seem to have never been systematically noticed or discussed at all until the latter part of the 20th century, when finally the framework of “fractals” was developed for talking about them. </p>\n<p>And so it may be with many of the forms we’ve seen here. As of today, we have no name for them, no systematic framework for thinking about them, and no reason to view them as important. But particularly if the things we do repeatedly show us such forms, we’ll eventually come up with names for them, and start incorporating them into the domain that our minds cover. </p>\n<p>And in a sense what we’ve done here can be thought of as showing us a preview of what’s out there in rulial space, in what’s currently the domain of alien minds. In the general exploration of <a href=\"https://writings.stephenwolfram.com/category/ruliology/\">ruliology</a>, and the investigation of what arbitrary simple programs in the computational universe do, we’re able to jump far across the ruliad. But it’s typical that what we see is not something we can connect to things we’re familiar with. In what we’re doing here, we’re moving only much smaller distances in rulial space. We’re starting from generative AI that’s closely aligned with current human development—having been trained from images that we humans have put on the web, etc. But then we’re making small changes to our “AI mind”, and looking at what it now generates. </p>\n<p>What we see is often surprising. But it’s still close enough to where we “currently are” in rulial space that we can—at least to some extent—absorb and reason about what we’re seeing. Still, the images often don’t “make sense” to us. And, yes, quite possibly the AI has invented something that has a rich and “meaningful” inner structure. But it’s just that we don’t (yet) have a way to talk about it—and if we did, it would immediately “make perfect sense” to us. </p>\n<p>So if we see something we don’t understand, can we just “train a translator”? At some level the answer must be yes. Because the <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a> implies that ultimately there’s a fundamental uniformity to the ruliad. But the problem is that the translator is likely to have to do an <a href=\"https://www.wolframscience.com/nks/p737--computational-irreducibility/\">irreducible amount of computational work</a>. And so it won’t be implementable by a “mind like ours”. Still, even though we can’t create a “general translator” we can expect that certain features of what we see will still be translatable—in effect by exploiting certain pockets of computational reducibility that must necessarily exist even when the system as a whole is full of computational irreducibility. And operationally what this means in our case is that the AI may in effect have found certain regularities or patterns that we don’t happen to have noticed but that are useful in exploring further from the “current human point” in rulial space.</p>\n<p>It’s very challenging to get an intuitive understanding of what rulial space is like. But the approach we’ve taken here is for me a promising first effort in “humanizing” rulial space, and seeing just how we might be able to relate to what is so far the domain of alien minds. </p>\n<hr style=\"border-width: 2px;margin-bottom: 2rem;\">\n<h2 id=\"appendix-how-does-the-generative-ai-work\">Appendix: How Does the Generative AI Work?</h2>\n<p>In the main part of this piece, we’ve mostly just talked about what generative AI does, not how it works inside. Here I’ll go a little deeper into what’s inside the particular type of generative AI system that I’ve used in my explorations. It’s a <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/Stable-Diffusion-V1/\">method called stable diffusion</a>, and its operation is in many ways both clever and surprising. As it’s implemented today it’s steeped in fairly complicated engineering details. To what extent these will ultimately be necessary isn’t clear. But in any case here I’ll mostly concentrate on general principles, and on giving a broad outline of how generative AI can be used to produce images.</p>\n<h3 id=\"the-distribution-of-typical-images\">The Distribution of Typical Images</h3>\n<p>At the core of generative AI is the ability to produce things of some particular type that “follow the patterns of” known things of that type. So, for example, <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">large language models (LLMs)</a> are intended to produce text that “follows the patterns” of text written by humans, say on the web. And generative AI systems for images are similarly intended to produce images that “follow the patterns” of images put on the web, etc. </p>\n<p>But what kinds of patterns exist in typical images, say on the web? Here are some examples of “typical images”—scaled down to 32×32 pixels and taken from a <a href=\"https://datarepository.wolframcloud.com/resources/CIFAR-100/\" target=\"_blank\" rel=\"noopener\">standard set of 60,000 images</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img1.png' alt='' title='' width='642' height='155'> </div>\n</p></div>\n<p>And as a very first thing, we can ask what colors show up in these images. They’re not uniform in RGB space: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img2.png' alt='' title='' width='192' height='72'> </div>\n</p></div>\n<p>But what about the positions of different colors? Adjusting to accentuate color differences, the “average image” turns out to have a curious “HAL’s eye” look (presumably with blue for sky at the top, and brown for earth at the bottom): </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img3.png' alt='' title='' width='67' height='67'> </div>\n</p></div>\n<p>But just picking pixels separately—even with the color distribution inferred from actual images—won’t produce images that in any way look “natural” or “realistic”: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img4.png' alt='' title='' width='630' height='48'> </div>\n</p></div>\n<p>And the immediate issue is that the pixels aren’t really independent; most pixels in most images are correlated in color with nearby pixels. And in a first approximation one can capture this for example by <a href=\"https://reference.wolfram.com/language/ref/LearnDistribution.html\">fitting the list of colors of all the pixels</a> to a multivariate Gaussian distribution with a covariance matrix that represents their correlation. <a href=\"https://reference.wolfram.com/language/ref/RandomVariate.html\">Sampling from this distribution</a> gives images like these—that indeed look somehow “statistically natural”, even if there isn’t appropriate detailed structure in them:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img5A.png' alt='' title='' width='630' height='158'> </div>\n</p></div>\n<p>So, OK, how can one do better? The basic idea is to use neural nets, which can in effect encode detailed long-range connections between pixels. In some way it’s similar to <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#inside-chatgpt\">what’s done in LLMs like ChatGPT</a>—where one has to deal with long-range connections between words in text. But for images it’s structurally a bit more difficult, because in some sense one has to “consistently fit together 2D patches” rather than just progressively extend a 1D sequence.</p>\n<p>And the typical way this is done at first seems a bit bizarre. The basic idea is to start with a random array of pixels—corresponding in effect to “pure noise”—and then progressively to “reduce the noise” to end up with a “reasonable image” that follows the patterns of typical images, all the while guided by some prompt that says what one wants the “reasonable image” to be of.</p>\n<h3 id=\"attractors-and-inverse-diffusion\">Attractors and Inverse Diffusion</h3>\n<p>How does one go from randomness to definite “reasonable” things? The key is to use the <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-7--the-notion-of-attractors\">notion of attractors</a>. In a very simple case, one might have a system—like this “mechanical” example—where from any “randomly chosen” initial condition one also evolves to one of (here) two definite (fixed-point) attractors:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img6.png' alt='' title='' width='573' height='62'> </div>\n</p></div>\n<p>One has something similar in a neural net that’s for example <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/050b1a0a-f43a-4c28-b7e0-72607a918467/\">trained to recognize digits</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img7.png' alt='' title='' width='649' height='30'> </div>\n</p></div>\n<p>Regardless of exactly how each digit is written, or noise that gets added to it, the network will take this input and evolve to an attractor corresponding to a digit. </p>\n<p>Sometimes there can be lots of attractors. Like in <a href=\"https://www.wolframscience.com/nks/chap-6--starting-from-randomness#sect-6-2--four-classes-of-behavior\">this (“class 2”) cellular automaton</a> evolving down the page, many different initial conditions can lead to the same attractor, but there are many possible attractors, corresponding to different final patterns of stripes:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img8.png' alt='' title='' width='665' height='75'> </div>\n</p></div>\n<p>The same can be true for example in 2D cellular automata, where now the attractors can be thought of as being different “images” with structure determined by the cellular automaton rule:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img9.png' alt='' title='' width='679' height='172'> </div>\n</p></div>\n<p>But what if one wants to arrange to have particular images as attractors? Here’s where the somewhat surprising idea of “stable diffusion” can be used. Imagine we start with two possible images, <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" /> and <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />, and then in a series of steps progressively add noise to them:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img10.png' alt='' title='' width='679' height='192'> </div>\n</p></div>\n<p>Here’s the bizarre thing we now want to do: train a neural net to take the image we get at a particular step, and “go backwards”, removing noise from it. The neural net we’ll use for this is somewhat complicated, with “<a href=\"https://reference.wolfram.com/language/ref/ConvolutionLayer.html\">convolutional</a>” pieces that basically operate on blocks of nearby pixels, and “<a href=\"https://reference.wolfram.com/language/ref/AttentionLayer.html\">transformers</a>” that get applied with certain weights to more distant pixels. Schematically in <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> the <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/Stable-Diffusion-V1/\">network looks at a high level like this</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img11.png' alt='' title='' width='594' height='278'> </div>\n</p></div>\n<p>And roughly what it’s doing is to make an informationally compressed version of each image, and then to expand it again (through what is usually called a “U-net” neural net). We start with an untrained version of this network (say just randomly initialized). Then we feed it a couple of million examples of noisy pictures of <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" /> and <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />, and the denoised outputs we want in each case. </p>\n<p>Then if we take the trained neural net and successively apply it, for example, to a “noised <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />”, the net will “correctly” determine that the “denoised” version is a “pure <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img12.png' alt='' title='' width='370' height='28'> </div>\n</p></div>\n<p>But what if we apply this network to pure noise? The network has been set up to always eventually evolve either to the “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />” attractor or the “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />” attractor. But which it “chooses” in a particular case will depend on the details of the initial noise—so in effect the network will seem to be picking at random to “fish” either “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />” or “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />” out of the noise:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img13.png' alt='' title='' width='572' height='164'> </div>\n</p></div>\n<p>How does this apply to our original goal of generating images “like” those found for example on the web? Well, instead of just training our “denoising” (or “inverse diffusion”) network on a couple of “target” images, let’s imagine we train it on billions of images from the web. And let’s also assume that our network isn’t big enough to store all those images in any kind of explicit way.</p>\n<p>In the abstract it’s not clear what the network will do. But the remarkable empirical fact is that it seems to manage to successfully generate (“from noise”) images that “follow the general patterns” of the images it was trained from. There isn’t any clear way to “formally validate” this success. It’s really just a matter of human perception: to us the images (generally) “look right”. </p>\n<p>It could be that with a different (alien?) <a href=\"https://www.wolframscience.com/nks/chap-10--processes-of-perception-and-analysis/\">system of perception</a> we’d immediately see “something wrong” with the images. But for purposes of human perception, the neural net seems to give “reasonable-looking” images—perhaps not least because the neural net operates at least approximately like our brains and our processes of perception seem to operate. </p>\n<h3 id=\"injecting-a-prompt\">Injecting a Prompt</h3>\n<p>We’ve described how a denoising neural net seems to be able to start from some configuration of random noise and generate a “reasonable-looking” image. And from any particular configuration of noise, a given neural net will always generate the same image. But there’s no way to tell what that image will be of; it’s just something to empirically explore, as we did above.</p>\n<p>But what if we want to “guide” the neural net to generate an image that we’d describe as being of a definite thing, like “a cat in a party hat”? We could imagine “continually checking” whether the image we’re generating would be recognized by a neural net as being of what we wanted. And conceptually that’s what we can do. But we also need a way to “redirect” the image generation if it’s “not going in the right direction”. And a convenient way to do this is to mix a “description of what we want” right into the denoising training process. In particular, if we’re training to “recover an <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />”, mix a description of the “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />” right alongside the image of the “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/A2helvetica.png\" alt=\"\" width=\"11\" height=\"15\" />”.</p>\n<p>And here we can make use of a key feature of neural nets: that ultimately they operate on arrays of (real) numbers. So whether they’re dealing with images composed of pixels, or text composed of words, all these things eventually have to be “ground up” into arrays of real numbers. And when a neural net is trained, what it’s ultimately “learning” is just how to appropriately transform these “disembodied” arrays of numbers. </p>\n<p>There’s a fairly natural way to generate an array of numbers from an image: just take the triples of red, green and blue intensity values for each pixel. (Yes, we could pick a different detailed representation, but it’s not likely to matter—because the neural net can always effectively “learn a conversion”.) But what about a textual description, like “a cat in a party hat”?</p>\n<p>We need to find a way to encode text as an array of numbers. And actually LLMs face the same issue, and we can solve it in basically <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#the-concept-of-embeddings\">the same way here as LLMs do</a>. In the end what we want is to derive from any piece of text a “feature vector” consisting of an array of numbers that provide some kind of representation of the “effective meaning” of the text, or at least the “effective meaning” relevant to describing images. </p>\n<p>Let’s say we train a neural net to reproduce associations between images and captions, as found for example on the web. If we feed this neural net an image, it’ll try to generate a caption for the image. If we feed the neural net a caption, it’s not realistic for it to generate a whole image. But we can look at the innards of the neural net and see the array of numbers it derived from the caption—and then use this as our feature vector. And the idea is that because captions that “mean the same thing” should be associated in the training set with “the same kind of images”, they should have similar feature vectors. </p>\n<p>So now let’s say we want to generate a picture of a cat in a party hat. First we find the feature vector associated with the text “a cat in a party hat”. Then this is what we keep mixing in at each stage of denoising to guide the denoising process, and end up with an image that the image captioning network will identify as “a cat in a party hat”.</p>\n<h3 id=\"the-latent-space-“trick”\">The Latent Space “Trick”</h3>\n<p>The most direct way to do “denoising” is to operate directly on the pixels in an image. But it turns out there’s a considerably more efficient approach, which operates not on pixels but on “features” of the image—or, more specifically, on a feature vector which describes an image. </p>\n<p>In a “raw image” presented in terms of pixels, there’s a lot of redundancy—which is why, for example, image formats like JPEG and PNG manage to compress raw images so much without even noticeably modifying them for purposes of typical human perception. But with neural nets it’s possible to do much greater compression, particularly if all we want to do is to preserve the “meaning” of an image, without worrying about its precise details.</p>\n<p>And in fact as part of training a neural net to associate images with captions, we can derive a “latent representation” of images, or in effect a feature vector that captures the “important features” of the image. And then we can do everything we’ve discussed so far directly on this latent representation—decoding it only at the end into the actual pixel representation of the image.</p>\n<p>So what does it look like to build up the latent representation of an image? With the particular setup we’re using here, it turns out that the feature vector in the latent representation still preserves the basic spatial arrangement of the image. The “latent pixels” are much coarser than the “visible” ones, and happen to be characterized by 4 numbers rather than the 3 for RGB. But we can decode things to see the “denoising” process happening in terms of “latent pixels”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071323sec7img14.png' alt='' title='' width='658' height='67'> </div>\n</p></div>\n<p>And then we can take the latent representation we get, and once again use a trained neural net to fill in a “decoding” of this in terms of actual pixels, getting out our final generated image.</p>\n<h2 id=\"an-analogy-in-simple-programs\">An Analogy in Simple Programs</h2>\n<p>Generative AI systems work by having attractors that are carefully constructed through training so that they correspond to “reasonable outputs”. A large part of what we’ve done above is to study what happens to these attractors when we change the internal parameters of the system (neural net weights, etc.). What we’ve seen has been complicated, and, indeed, often quite “alien looking”. But is there perhaps a simpler setup in which we can see similar core phenomena?</p>\n<p>By the time we’re thinking about creating attractors for realistic images, etc. it’s inevitable that things are going to be complicated. But what if we look at systems with much simpler setups? For example, consider a dynamical system whose state is characterized just by a single number—such as an iterated map on the interval, like <em>x</em> <img title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071123rightarrow.png\" alt=\"\" width=\"16\" height=\"10\" /> <em>a</em> <em>x</em> (1 – <em>x</em>).</p>\n<p>Starting from a uniform array of possible <em>x</em> values, we can show down the page which values of <em>x</em> are achieved at successive iterations:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img1.png' alt='' title='' width='613' height='180'> </div>\n</p></div>\n<p>For <em>a</em> = 2.9, the system evolves from any initial value to a single attractor, which consists of a single fixed final value. But if we change the “internal parameter” <em>a</em> to 3.1, we now get two distinct final values. And at the “bifurcation point” <em>a</em> = 3 there’s a sudden change from one to two distinct final values. And indeed in our generative AI system it’s fairly common to see similar discontinuous changes in behavior even when an internal parameter is continuously changed.</p>\n<p>As another example—slightly closer to image generation—consider (as above) a 1D cellular automaton that exhibits class 2 behavior, and evolves from any initial state to some fixed final state that one can think of as an attractor for the system:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img2.png' alt='' title='' width='575' height='148'> </div>\n</p></div>\n<p>Which attractor one reaches depends on the initial condition one starts from. But—in analogy to our generative AI system—we can think of all the attractors as being “reasonable outputs” for the system. But now what happens if we change the parameters of the system, or in this case, the cellular automaton rule? In particular, what will happen to the attractors? It’s like what we did above in changing weights in a neural net—but a lot simpler.</p>\n<p>The particular rule we’re using here has 4 possible colors for each cell, and is defined by just 64 discrete values from 0 to 3. So let’s say we randomly change just one of those values at a time. Here are some examples of what we get, always starting from the same initial condition as in the first picture above: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img3.png' alt='' title='' width='596' height='285'> </div>\n</p></div>\n<p>With a couple of exceptions these seem to produce results that are at least “roughly similar” to what we got without changing the rule. In analogy to what we did above, the cat might have changed, but it’s still more or less a cat. But let’s now try “progressive randomization”, where we modify successively more values in the definition of the rule. For a while we again get “roughly similar” results, but then—much like in our cat examples above—things eventually “fall apart” and we get “much more random” results:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img4.png' alt='' title='' width='596' height='285'> </div>\n</p></div>\n<p>One important difference between “stable diffusion” and cellular automata is that while in cellular automata, the evolution can lead to continued change forever, in stable diffusion there’s an annealing process used that always makes successive steps “progressively smaller”—and essentially forces a fixed point to be reached.</p>\n<p>But notwithstanding this, we can try to get a closer analogy to image generation by looking (again as above) at 2D cellular automata. Here’s an example of the (not-too-exciting-as-images) “final states” reached from three different initial states in a particular rule:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img5.png' alt='' title='' width='573' height='181'> </div>\n</p></div>\n<p>And here’s what happens if one progressively changes the rule:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/07/sw071123sec8img6.png' alt='' title='' width='594' height='229'> </div>\n</p></div>\n<p>At first one still gets “reasonable-according-to-the-original-rule” final states. But if one changes the rule further, things get “more alien”, until they look to us quite random. </p>\n<p>In changing the rule, one is in effect “<a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/#motion-in-rulial-space\">moving in rulial space</a>”. And by looking at how this works in cellular automata, one can get a certain amount of intuition. (<a href=\"https://www.wolframscience.com/nks/p391--fundamental-issues-in-biology/\">Changes to the rule</a> in a cellular automaton seem a bit like “changes to the genotype” in biology—with the behavior of the cellular automaton representing the corresponding “phenotype”.) But seeing how “rulial motion” works in a generative AI that’s been trained on “human-style input” gives a more accessible and humanized picture of what’s going on, even if it seems still further out of reach in terms of any kind of traditional explicit formalization.</p>\n<h2 id='thanks' style='font-size:1.2rem'>Thanks</h2>\n<p style='font-size:90%'>This project is the first I’ve been able to do with our new <a href=\"https://www.wolframinstitute.org/\">Wolfram Institute</a>.

And over the past 36 years, Notebooks have proved to be an incredibly convenient medium in which to do—and <a href=\"https://writings.stephenwolfram.com/2019/10/the-new-world-of-notebook-publishing/\">publish</a>—work (and indeed, I, for example, <a href=\"https://writings.stephenwolfram.com/2012/03/the-personal-analytics-of-my-life/\">have created</a> hundreds of thousands of them). And, yes, eventually the basic concepts of Notebooks were widely copied—though still not even with everything we had back in 1987!</p>\n<p>Well, now there’s a new challenge and opportunity for Notebooks: integrating LLM functionality into them. It’s an interesting design problem, and I’m pretty pleased with what we’ve come up with. And today we’re introducing Chat Notebooks as a new kind of Notebook that supports LLM-based chat functionality.<span id=\"more-51358\"></span></p>\n<div id=\"gpt-stripe\" style=\"background: #f6fcff87;padding: 0.75rem 1.5rem;border: 1px solid #aeccd987;font-family: 'Source Sans Pro', sans-serif;margin-bottom: 2.5rem;max-width: 620px;/* font-size: .6rem; */\">\n<p style=\"font-size: .85rem;color: #3f5f6a;line-height: 1.5;padding-bottom: 0;display: inline;\">The functionality described here will be built into the upcoming version of <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> (Version 13.3).

One that I’m particularly excited about—especially because of its potential to open up computational language to so many people—is for providing interactive <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> assistance. But I’ll talk about that separately. And instead here I’ll concentrate on the (already very rich) general concept of Chat Notebooks.</p>\n<p>The basic idea is simple: there’s a new kind of cell—a chat cell—that communicates with an LLM. (In what we’re calling “Chat-Driven Notebooks” chat cells are the default; in “Chat-Enabled Notebooks” you get a chat cell by pressing <span class=\"kbd\"><kbd>'</kbd></span>—i.e. quote—when you first create the cell.)</p>\n<table>\n<tbody>\n<tr>\n<td colspan='1' rowspan='1' class='Input'>\n<div>\n\t\t\t\t\t<video loading='lazy' height=\"auto\" width=\"639\" style=\"margin-left:0px\" muted=\"\" alt=\"Crocodile joke chat\" title=\"Crocodile joke chat\" style=\"margin-bottom: -15px\" src=\"https://content.wolfram.com/sites/43/2023/06/Crocodile-Joke-v2.mp4\" autoplay=\"\" loop=\"\" playsinline><br />\n</video>\n\t\t\t\t</div>\n<div class='IFL'\n\t\t\t\t\t<span class='close' id='z13_out_text'></span></p>\n<pre class='text' id='z13_out_text'></pre>\n</p></div>\n</td>\n</tr>\n</tbody>\n</table>\n<p>In a standard Notebook, we’re used to having input cells containing Wolfram Language, together with output cells that give the results from evaluating that Wolfram Language input:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg3.png' alt='' title='' width='404' height='89'> </div>\n</p></div>\n<p>And at a basic level, a chat cell is just a type of cell that uses an LLM—rather than the Wolfram Language kernel—to “evaluate” its output. And indeed, in a Chat Notebook, the way you send your input to the LLM is to press <span class=\"kbd\"><kbd>shift</kbd><kbd>enter</kbd></span>, just like for Wolfram Language input.</p>\n<p>And just like for standard input and output cells, chat input and output cells are grouped, so you can select them together, or double-click one of them to open or close them:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723croc-dataset-2.gif' alt='Opening and closing cells' title='Opening and closing cells' width='500' height='116'/></p>\n<p>One immediate difference with chat cells is that whereas an ordinary output cell is produced all at once, the contents of a chat output cell progressively “stream in” a word (or so) at a time, as the LLM generates it.</p>\n<p>There’s another important difference too. In an ordinary Notebook there’s a “temporal thread of evaluation” in which inputs and outputs appear in the sequence they’re generated in time (as indicated by <tt>In[<em>n</em>]</tt> and <tt>Out[<em>n</em>]</tt>, quite independent of where they are placed in the Notebook. Thus, for example, if you evaluate <tt>x = 5</tt> in an input cell, then subsequently ask for the value of <tt>x</tt>, the result will be 5 wherever in the notebook you ask—even if it’s above the “<tt>x = 5</tt>” cell:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg7A.png' alt='x = 5 calculations' title='x = 5 calculations' width='224' height='109'/></p>\n<p>But with chat cells it’s a different story. Now the order of cells in the Notebook matters. The “thread of a chat” is determined not by when chat cells were evaluated, but instead by the order in which they appear in the notebook. </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg8.png' alt='Order of chat cells in thread' title='Order of chat cells in thread' width='695' height='286'/></p>\n<p>Going down the notebook, successive chat cells are “aware” of what’s in cells above them. But even if we add it later, a cell placed at the top won’t “know about” anything in cells below it.</p>\n<p>All of this reflects an important difference between ordinary Wolfram Language evaluation and “LLM evaluation”. In Wolfram Language evaluation, the Wolfram Language kernel always has an internal state, and whatever you do in the notebook is in a sense merely a window into that state. But for LLM evaluation the whole state is determined by the actual content of the notebook.</p>\n<p>And each time you do an LLM evaluation, the Notebook system will package up all the content above the cell in which you’re doing the evaluation, and send it to the LLM. The LLM in a sense never knows anything about time history; all it knows is what’s in the notebook when the LLM evaluation is done.</p>\n<p>There are many consequences of this. One is that you can edit the chat history and “reevaluate with new history”. When the reevaluation “overwrites” a cell, the Chat Notebook will maintain the older version, and you can get back to it by pressing the <span class=\"kbd\"><kbd style=\"color: gray;font-size: 12px;padding: 0 .18rem 0 .1rem;\">◄</kbd></span><span class=\"kbd\"><kbd style=\"color: gray;font-size: 12px; padding: 0 .1rem 0 .18rem;\">►</kbd></span> arrows (for purposes of LLM evaluation, the chat history is always considered to be what’s showing when you do the evaluation):</p>\n<table>\n<tbody>\n<tr>\n<td colspan='1' rowspan='1' class='Input'>\n<div>\n\t\t\t\t\t<video loading='lazy' height=\"auto\" width=\"639\" style=\"margin-left:0px\" muted=\"\" alt=\"Name change chat scenario\" title=\"Name change chat scenario\" src=\"https://content.wolfram.com/sites/43/2023/06/BobBill-2.mp4\" autoplay=\"\" loop=\"\" playsinline><br />\n</video>\n\t\t\t\t</div>\n</td>\n</tr>\n</tbody>\n</table>\n<p>LLM evaluations pick up content that appears above them in the notebook. But there’s an important way to limit this, and to separate or “modularize” chats: the idea of a chatblock. </p>\n<p>You can begin a chatblock by pressing <span class=\"kbd\"><kbd>~</kbd></span> (tilde) when you create a cell in the Notebook you’ll then get:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg12B.png' alt='Chatblock separator' title='Chatblock separator' width='620' height='30'/></p>\n<p>And the point is that this indicates the beginning of a new chat. When you evaluate a chat cell below this separator, it’ll only use content up to the separator—so that means that in a single Chat Notebook, you can have any number of independent “chat sessions”, delimited by chatblock separators:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg13.png' alt='Name chat' title='Name chat' width='620' height='477'/></p>\n<p>In a sense LLM evaluation is a very Notebook-centric form of evaluation, always based on the sequence of content that appears in the Notebook. As we’ll discuss below, there are different detailed forms of LLM evaluation, but in most cases the evaluation will operate not just on chat cells, but on all cells that appear above it in a given chatblock.</p>\n<p>Another difference from ordinary evaluation is that LLM evaluation can often not be repeatable. Yes, if there are random numbers, or external inputs, ordinary Wolfram Language evaluation may not be repeatable. But the core evaluation process in Wolfram Language is completely repeatable. In an LLM, however, that may not be the case. For example, particularly if the LLM is operated with a nonzero value of its “temperature” parameter (which is usually the default), it’s pretty much guaranteed to give different results every time an evaluation is done. </p>\n<p>And in using Chat Notebooks, it’ll sometimes be convenient to just try to evaluate a chat cell multiple times until you get what you want. (You can go between different choices using <nobr>the <span class=\"kbd\"><kbd style=\"color: gray;font-size: 12px;padding: 0 .18rem 0 .1rem;\">◄</kbd></span><span class=\"kbd\"><kbd style=\"color: gray;font-size: 12px; padding: 0 .1rem 0 .18rem;\">►</kbd></span> arrows.)</nobr> Another helpful “trick” in Chat Notebooks is to edit not just your input, but also the output generated from LLM evaluation. When you do an LLM evaluation, the LLM is just given whatever appears above in the Notebook, regardless of where that “came from”. So if the LLM “makes a mistake” you can just fix it yourself, and then the LLM will typically “pick up the fix” when it comes to do later evaluations.</p>\n<p>The default in Chat Notebooks is always to use previous cells as “context” for any chat input you provide. But there’s also a mechanism for having “side chats” that don’t use (or affect) context. Instead of just typing to get a chat cell (in a Chat-Driven Notebook), start the cell with <span class=\"kbd\"><kbd>'</kbd></span> (“quote”) to get a “side chat” cell (in a Chat-Enabled Notebook, it’s <span class=\"kbd\"><kbd>'</kbd></span> to get a chat cell, and <span class=\"kbd\"><kbd>'</kbd></span><span class=\"kbd\"><kbd>'</kbd></span> to get a side chat cell):</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg15.png' alt='Side chat cell' title='Side chat cell' width='613' height='137'/></p>\n<h2 id=\"who-are-you-gonna-talk-to\">Who Are You Gonna Talk To?</h2>\n<p>When you evaluate a chat cell, you’ll get a response from an LLM. But what determines the “persona” that’ll be used for the LLM—or in general how the LLM is configured? There are multiple levels at which this can be specified—from overall <tt>Preference</tt> settings to Chat Notebook settings to chatblocks to individual chat cells. </p>\n<p>For a chatblock, for example, click the little chat icon to the left and you’ll see a menu of possible personas:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg16.png' alt='Personas menu' title='Personas menu' width='620' height='246'/></p>\n<p>Pick a particular persona and its icon will show up “perched” on the chatblock separator—and then in every chat cell that follows it’ll be that persona that by default responds to you: </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg17B.png' alt='Birdnardo query' title='Birdnardo query' width='620' height='149'/></p>\n<p>You can tell it’s that persona responding because its icon will show up as the “label” for the response. (It’ll also appear next to your input if you hover over the chat cell icon).</p>\n<p>We mentioned in passing above that when there are two kinds of Chat Notebooks you can create (e.g. with the <tt>File</tt> > <tt>New</tt> menu): Chat-Enabled Notebooks and Chat-Driven Notebooks. In future versions of the Wolfram Notebook system, Chat-Enabled Notebooks will probably be the standard default for all new notebooks, but for now it’s something you have to explicitly choose. </p>\n<p>So what is a Chat-Enabled Notebook, and how is it different from a Chat-Driven Notebook? The basic point is that a Chat-Enabled Notebook is intended to be used just like Wolfram Notebooks have been used for 35 years—but with additional chat capabilities added. In a Chat-Enabled Notebook the default new cell type (assuming you’re using the default stylesheet) expects Wolfram Language input. To get a chat cell, you explicitly type <span class=\"kbd\"><kbd>'</kbd></span> (“quote”) at the beginning of the cell. And when you make that chat cell, it’ll by default be talking to the Code Assistant persona, ready to help you with generating Wolfram Language code.</p>\n<p>A Chat-Driven Notebook is something different: it’s a notebook where chats are the primary content—and by default new cells are always chat cells, and there’s no particular expectation that you’ll be talking about things to do with Wolfram Language. There’s no special persona by default in Chat-Driven Notebook, and instead one’s pretty much just talking to the generic LLM (though there’s some additional prompting about being used in a Notebook, etc.) </p>\n<p>If you want to talk to another persona, though, you can specify that in the menu of personas. There are a few personas listed by default. But there are <a href=\"https://resources.wolframcloud.com/PromptRepository/category/personas\">many more in the Wolfram Prompt Repository</a>. And from <tt>Add & Manage Personas </tt>you can open the personas section of the Prompt Repository: </p>\n<p><a href=\"https://resources.wolframcloud.com/PromptRepository/category/personas\"><img src='https://content.wolfram.com/sites/43/2023/06/sw060723prompt-repo-menu-v3.png' alt='Wolfram Prompt Repository personas' title='Wolfram Prompt Repository personas' width='618' height='527'/></a></p>\n<p>Then you can go to a persona page, and press the <span class=\"kbd\"><kbd>Install</kbd></span> button to install that persona in your session:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/genzspeak-v5.png' alt='GenZSpeak persona' title='GenZSpeak persona' width='620' height='250'/></p>\n<p>Now you’ll be able to select this persona from any chatblock, chat cell, etc. persona menu:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg20.png' alt='GenZSpeak chat' title='GenZSpeak chat' width='620' height='131'/></p>\n<p>The Wolfram Prompt Repository contains a growing selection of curated contributed personas. But the <tt>Install from URL </tt>menu item also lets you install personas that have been independently deployed (for example in the <a href=\"https://www.wolframcloud.com/\">Wolfram Cloud</a>), and are available either publicly or for specific users. (<a href=\"https://writings.stephenwolfram.com/2023/06/prompts-for-work-play-launching-the-wolfram-prompt-repository/#adding-your-own-prompts\">As discussed elsewhere</a>, you can create personas using a Prompt Resource Definition Notebook.)</p>\n<p>Given a named persona—either defined in the Wolfram Prompt Repository, or that you’ve explicitly installed—you can always “direct chat” that persona in a particular chat cell by using <span class=\"promptformatted\">@persona</span>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg21.png' alt='Chat query about feathers' title='Chat query about feathers' width='620' height='300'/></p>\n<p>When you direct chat a persona in a particular chat cell, that persona gets sent the whole previous history in your current chatblock. But after that persona has responded, subsequent chat cells revert to using the current default persona. Nevertheless, any persona that you direct chat will automatically get installed in the list of personas you can use. Note, by the way, that direct chatting is an independent idea from side chats. Side chats don’t by default affect what persona you’re talking to, but give you a “localized” context, while direct chats affect the persona you’re talking to, but are “flowed into” the global history of the current chatblock.</p>\n<p>Personas let you define all sorts of aspects of how you want an LLM to behave. But ultimately you also have to define the underlying LLM itself. What model should it use? With what “temperature”? etc. At the bottom of the same menus that list personas there’s an <tt>Advanced Settings</tt> item:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg22.png' alt='Advanced Settings menu' title='Advanced Settings menu' width='420' height='225'/></p>\n<p>Like personas, these can be set at a chat cell level, chatblock level, notebook level—or globally, through <tt>Preferences</tt> settings. It’s typical to define things like authentication at the <tt>Preferences</tt> level. And ultimately everything about the configuration of an LLM is specified by a symbolic <a href=\"https://reference.wolfram.com/language/ref/LLMConfiguration.html\"><tt>LLMConfiguration</tt></a> object.</p>\n<p>As we’ll discuss elsewhere, a very important additional feature of full <a href=\"https://reference.wolfram.com/language/ref/LLMConfiguration.html\"><tt>LLMConfiguration</tt></a> objects is that they can specify “tools” that should be available to an LLM—essentially Wolfram Language APIs that the LLM should be able to send requests to in order to get computational results or computational actions. </p>\n<p>Within a particular Wolfram Language session, you can specify a default LLM configuration by setting the value of <a href=\"https://reference.wolfram.com/language/ref/$LLMEvaluator.html\"><tt>$LLMEvaluator</tt></a>. You can also programmatically create a Chat Notebook with a specified LLM configuration using: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg23_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg23B.png' alt='' title='' width='550' height='291'> </div>\n</p></div>\n<p>(This will make a chat-driven notebook; you can use <tt>\"ChatEnabled\"</tt> to make a chat-enabled notebook.)</p>\n<h2 id=\"applying-functions-in-a-chat-notebook\">Applying Functions in a Chat Notebook</h2>\n<p>As we discussed elsewhere, personas are ultimately just prompts. So when, for example, we say <span class=\"promptformatted\"><a href=\"https://resources.wolframcloud.com/PromptRepository/resources/Yoda/\">@Yoda</a></span> we’re really just adding the “Yoda prompt” (i.e. <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</a>[\"Yoda\"]</tt>) into a chat evaluation. </p>\n<p>But there are all sorts of prompts that don’t correspond to what we’d normally think of as personas. For example, there are “modifier prompts”, like <span class=\"promptformatted\"><a href=\"https://resources.wolframcloud.com/PromptRepository/resources/Emojified/\">Emojified</a></span> or <span class=\"promptformatted\"><a href=\"https://resources.wolframcloud.com/PromptRepository/resources/SEOOptimize/\">SEOptimize</a></span> or <span class=\"promptformatted\"><a href=\"https://resources.wolframcloud.com/PromptRepository/resources/TweetConvert/\">TweetConvert</a></span>, that describe particular output we want to get. And in a Chat Notebook, we can add such modifier prompts just using <span class=\"promptformatted\">#</span><em>prompt</em>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg24.png' alt='HaikuStyled chat modifier' title='HaikuStyled chat modifier' width='620' height='141'/></p>\n<p>The reason this works is that “under the hood”, a chat evaluation is effectively <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</a>[\"input\"]</tt>, and adding either a persona or a modifier prompt is achieved with <tt><a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\">LLMSynthesize</a>[<a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\">LLMPrompt</a>[</tt> … <tt>]]</tt>.</p>\n<p>You can add more than one modifier prompt just by putting in multiple <span class=\"promptformatted\">#</span> items. But what if a modifier prompt has a “parameter”, like in the case of <tt>\"<a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\">LLMPrompt</a>[\"Translated\", \"French\"]\"</tt>? Chat Notebooks provide a syntax for that, with each parameter separated by <span class=\"promptformatted\">|</span>, as in <span class=\"promptformatted\">#</span><em>prompt</em><span class=\"promptformatted\">|</span><em>parameter</em>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg25.png' alt='HaikuStyled and Translated chat modifiers' title='HaikuStyled and Translated chat modifiers' width='620' height='141'/></p>\n<p>Personas and modifiers are both intended to affect the output generated by an LLM in a chat. But the Wolfram Prompt Repository also contains “function prompts”, that are intended to operate on a specific piece of input you give. Function prompts are particularly suitable for programmatic use, as in: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg26_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg26.png' alt='' title='' width='649' height='43'> </div>\n</p></div>\n<p>But it’s also possible to use function prompts in Chat Notebooks. <span class=\"promptformatted\">!</span><em>prompt</em> specifies a function prompt:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg27.png' alt='FormalRephrase chat function prompt' title='FormalRephrase chat function prompt' width='620' height='106'/></p>\n<p>By default, a function prompt in a chat cell takes as its input the text you explicitly give in the chat cell (though it still “sees” previous history in the current chatblock.) But it’s also common to want to put the input in a cell of its own. You can make a function prompt take its input from the previous cell in the notebook by using <span class=\"promptformatted\">!</span><em>prompt</em><span class=\"promptformatted\">^</span>: </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg28.png' alt='FormalRephrase example' title='FormalRephrase example' width='620' height='143'/></p>\n<p>But what if you want to feed the complete history (in the current chatblock) to a function prompt? You can do that by using <span class=\"promptformatted\">^^</span> instead of <span class=\"promptformatted\">^</span>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg29.png' alt='Additional FormalRephrase example' title='Additional FormalRephrase example' width='620' height='235'/></p>\n<p>And, yes, there are a lot of little notations in Chat Notebooks. One gets used to them quickly, but here—for convenience—are all of them collected in a table:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723shortcuts-table-v5.png' alt='Chat Notebooks notation menu' title='Chat Notebook notation menu' width='620' height='424'/></p>\n<h2 id=\"the-design-of-chat-notebooks\">The Design of Chat Notebooks</h2>\n<p>One of the great long-term strengths of the Wolfram Language is the <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\">coherence of its design</a>. And that design coherence extends not only across the language itself, but also to the whole system around the language, including Wolfram Notebooks. So what about Chat Notebooks? As we said above, Chat Notebooks represent a new kind of Notebook—that have new kinds of requirements, and bring new design challenges. But as has happened so many times before, the whole Wolfram Language and Notebook paradigm turns out to be strong and general enough that we’ve been able to design Chat Notebooks so they fit coherently in with the rest of the system. And particularly for those (humans and AIs!) who know the existing system, it may be helpful to discuss some of the precedents and analogies for Chat Notebooks that exist elsewhere in the system.</p>\n<p>A key feature of Chat Notebooks is the concept of using a different evaluator for certain notebook content—in their case, an LLM evaluator for chat cells. But it turns out that the idea of having different evaluators is something that’s been around ever since we first invented Notebooks 36 years ago. Back in those days a common setup was a Notebook “front end” that could send evaluations either to a kernel running on your local machine, or <a href=\"https://reference.wolfram.com/language/workflow/UseASeparateKernelForEvaluation.html\">to remote kernels</a> running on other (perhaps more powerful) machines. (And, yes, there were shades of what we’d now call “<a href=\"https://www.wolframcloud.com/\">the cloud</a>”, though in those days remote computers often had phone connections, etc.)</p>\n<p>Right from the beginning we discussed having evaluators that weren’t directly based on what’s now Wolfram Language (and indeed at a programmatic level we provided plenty of <a href=\"https://reference.wolfram.com/language/guide/CallingExternalPrograms.html\">access to external programs</a>, etc.). But it was only when we <a href=\"https://www.wolframalpha.com/about\">released Wolfram|Alpha in 2009</a> that we finally had a compelling reason to think about integrating something other than Wolfram Language evaluation into the core user interface of Notebooks. Because then—through <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>’s natural language understanding capabilities—we had a way to specify Wolfram Language computations using something other than Wolfram Language: ordinary natural language. </p>\n<p>So this led us to introduce Wolfram|Alpha cells—where evaluation first interprets natural language you type, then does the Wolfram Language computation it specifies. You get a <a href=\"https://www.wolfram.com/language/fast-introduction-for-programmers/en/natural-language-input/\">Wolfram|Alpha cell by pressing <span class=\"kbd\"><kbd>=</kbd></span></a> when you create the cell (we also introduced the <a href=\"https://www.wolfram.com/language/fast-introduction-for-programmers/en/real-world-entities/\">inline <span class=\"kbd\"><kbd>control</kbd><kbd>=</kbd></span> mechanism</a>); then <span class=\"kbd\"><kbd>shift</kbd><kbd>enter</kbd></span> does the evaluation:</p>\n<p><img style=\"margin-left: 3px\" src='https://content.wolfram.com/sites/43/2023/06/sw060723Aimg31.png' alt='Wolfram|Alpha cell' title='Wolfram|Alpha cell' width='407' height='278'/></p>\n<p>In 2017 (with <a href=\"https://reference.wolfram.com/legacy/language/v11.2/\">Version 11.2</a>) the notion of access to “other evaluators” from notebooks took another step—with the introduction of external evaluation cells:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/python_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw060723python-print-hello.png' alt='External evaluation cell' title='External evaluation cell' width='620' height='66'/></div>\n</p></div>\n<p>And with this also came the notion of a menu of “possible evaluators”—a precursor to the personas menu of Chat Notebooks:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723python-menu.png' alt='External software menu' title='External software menu' width='233' height='210'/></p>\n<p>Then in 2019 came the introduction of <a href=\"https://writings.stephenwolfram.com/2019/09/the-ease-of-wolframalpha-the-power-of-mathematica-introducing-wolframalpha-notebook-edition/\">Wolfram|Alpha Notebook Edition,</a> with its whole framework around natural language “Wolfram|Alpha-style” input cells:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/sw060723notebook-edition.png' alt='Wolfram|Alpha Notebook Edition input cells' title='Wolfram|Alpha Notebook Edition input cells' width='620' height='543'/></p>\n<p>And in a sense this was the most direct precursor to Chat Notebooks. But now instead of having “free-form input” cells going to Wolfram|Alpha, we have chat cells going to an LLM. </p>\n<p>At a programmatic level, <a href=\"https://reference.wolfram.com/language/ref/ChatEvaluate.html\"><tt>ChatEvaluate</tt></a> (and <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a>) are in many ways not so different from <tt><a href=\"http://reference.wolfram.com/language/ref/CloudEvaluate.html\">CloudEvaluate</a></tt>, <tt><a href=\"http://reference.wolfram.com/language/ref/RemoteEvaluate.html\">RemoteEvaluate</a></tt> or <tt><a href=\"http://reference.wolfram.com/language/ref/ParallelEvaluate.html\">ParallelEvaluate</a></tt>. But what’s new is the Notebook interface aspect—which is what we’ve invented Chat Notebooks for. In things like <tt><a href=\"http://reference.wolfram.com/language/ref/ExternalEvaluate.html\">ExternalEvaluate</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/ParallelEvaluate.html\">ParallelEvaluate</a></tt> there’s a state maintained within the evaluator. But Wolfram|Alpha, for example, is typically stateless. So in <a href=\"https://www.wolfram.com/wolfram-alpha-notebook-edition/\">Wolfram|Alpha Notebook Edition</a> “state” is determined from previous cells in the notebook—which is essentially the same mechanism used in Chat Notebooks.</p>\n<p>But one of the new things in Chat Notebooks is that not only are previous cells that are somehow identified as “input” used to determine the “state”, but other cells (like text cells) are used as well. And, yes, ever since <a href=\"https://reference.wolfram.com/legacy/v3/\">Version 3</a> in 1996, there’ve been notebook programming constructs that have been able to process arbitrary notebook content. But Chat Notebooks are the first time “non-input” has been used in “evaluation”.</p>\n<p>Most of the defining features of Notebooks—like cells, cell groups, evaluation behavior, and so on—have been there ever since the beginning, back in 1988. But gradually over the years, we’ve progressively polished the concepts of Notebooks—introducing ideas like reverse-closed cells, template boxes, input ligatures, etc. And what’s remarkable to see now is how Chat Notebooks build on all these concepts.</p>\n<p>You can cut, copy, paste chat cells just like any other kinds of cells. You can close chat outputs, or reverse close chat inputs. It’s all the same as in the Notebook paradigm we’ve had for so long. But there are new ideas, like alternate outputs, chatblocks, etc. And no doubt over the months and years to come—as we see just how Chat Notebooks are used—we’ll invent ways to extend and polish the Chat Notebook experience. But as of now, it’s exciting to see how we’ve been able to take the paradigm that we invented more than 35 years ago and use it to deliver such a rich and powerful interface to those most modern of things: LLMs.</p>\n",

But it’s often convenient to use—or at least include—“pre-written” prompts, either ones that you’ve created and stored before, or ones that come from our new <a href=\"https://resources.wolframcloud.com/PromptRepository/\">Wolfram Prompt Repository</a>:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/05/sw052223WPR.png' alt='Wolfram Prompt Repository' title='Wolfram Prompt Repository' width='364' height='344'/></p>\n<p>Other posts in this series will talk in more detail about the Wolfram Prompt Repository—and about how it can be used in things like Chat Notebooks. But here we’re going to talk about how it can be used “programmatically” for LLM functions. </p>\n<p>The first approach is to use what we call “function prompts”—that are essentially pre-built <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> objects. There’s a whole section of function prompts in the Prompt Repository. As one example, let’s consider the <tt>\"<a href=\"https://resources.wolframcloud.com/PromptRepository/resources/Emojify/\">Emojify</a>\"</tt> function prompt. Here’s its page in the Prompt Repository:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/05/sw052223emojifyX.png' alt='Emojify page' title='Emojify page' width='506' height='385'/></p>\n<p>You can take any function prompt and apply it to specific text using <a href=\"https://reference.wolfram.com/language/ref/LLMResourceFunction.html\"><tt>LLMResourceFunction</tt></a>. Here’s what happens with the <tt>\"<a href=\"https://resources.wolframcloud.com/PromptRepository/resources/Emojify/\">Emojify</a>\"</tt> prompt:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg61_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg61.png' alt='' title='' width='606' height='55'> </div>\n</p></div>\n<p>And if you look at the pure result from <a href=\"https://reference.wolfram.com/language/ref/LLMResourceFunction.html\"><tt>LLMResourceFunction</tt></a>, we can see that it’s just an <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>—whose content was obtained from the Prompt Repository: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg62_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg62B.png' alt='' title='' width='276' height='82'> </div>\n</p></div>\n<p>Here’s another example: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg63_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg63.png' alt='' title='' width='670' height='46'> </div>\n</p></div>\n<p>And here we’re applying two different (but, in this particular case, approximately inverse) LLM functions from the Prompt Repository: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg64_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg64.png' alt='' title='' width='391' height='94'> </div>\n</p></div>\n<p><a href=\"https://reference.wolfram.com/language/ref/LLMResourceFunction.html\"><tt>LLMResourceFunction</tt></a> can take more than one argument:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg65A_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/w052223Aimg65B.png' alt='' title='' width='532' height='120'> </div>\n</p></div>\n<p>Something that we see here is that <a href=\"https://reference.wolfram.com/language/ref/LLMResourceFunction.html\"><tt>LLMResourceFunction</tt></a> can have an interpreter built into it—so that instead of just returning a string, it can return a computable (<a href=\"https://reference.wolfram.com/language/ref/interpreter/HeldExpression.html\">here held</a>) Wolfram Language expression. So, for example, the <tt>\"<a href=\"https://resources.wolframcloud.com/PromptRepository/resources/MovieSuggest\">MovieSuggest</a>\"</tt> prompt in the Prompt Repository is defined to include an interpreter that gives <tt>\"<a href=\"https://reference.wolfram.com/language/ref/entity/Movie.html\">Movie</a>\"</tt> entities</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Ximg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Ximg1.png' alt='' title='' width='624' height='100'> </div>\n</p></div>\n<p>from which we can do further computations, like:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Ximg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Ximg2.png' alt='' title='' width='609' height='330'> </div>\n</p></div>\n<p>Besides “function prompts”, another large section of the Prompt Repository is devoted to “persona” prompts. These are primarily intended for chats (“talk to a particular persona”), but they can also be used “programmatically” through <a href=\"https://reference.wolfram.com/language/ref/LLMResourceFunction.html\"><tt>LLMResourceFunction</tt></a> to ask for a single response “from the persona” to a particular input: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg66_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg66.png' alt='' title='' width='596' height='69'> </div>\n</p></div>\n<p>Beyond function and persona prompts, there’s a third major kind of prompt—that we call a “modifier prompt”—that’s intended to modify output from the LLM. An example of a modifier prompt is <tt>\"<a href=\"https://resources.wolframcloud.com/PromptRepository/resources/ELI5/\">ELI5</a>\"</tt> (“Explain Like I’m 5”). To “pull in” such a modifier prompt from the Prompt Repository, we use the general function <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a>. </p>\n<p>Say we’ve got an <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> set up: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg67_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg67.png' alt='' title='' width='490' height='70'> </div>\n</p></div>\n<p>To modify it with <tt>\"<a href=\"https://resources.wolframcloud.com/PromptRepository/resources/ELI5/\">ELI5</a>\"</tt>, we just insert <tt><a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a>[\"ELI5\"]</tt> into the “body” of the <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg68_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg68.png' alt='' title='' width='597' height='70'> </div>\n</p></div>\n<p>You can include multiple modifier prompts; some modifier prompts (like <tt>\"Translated\"</tt>) are set up to “take parameters” (here, the language to have the output translated into):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg69_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg69.png' alt='' title='' width='643' height='94'> </div>\n</p></div>\n<p>We’ll talk later in more detail about how this works.

Here we’re using the <tt>\"<a href=\"https://resources.wolframcloud.com/PromptRepository/resources/YesNo/\">YesNo</a>\"</tt> prompt, that forces a yes-or-no answer: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg71_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg71.png' alt='' title='' width='519' height='45'> </div>\n</p></div>\n<p>By the way, you can also use the <tt>\"<a href=\"https://resources.wolframcloud.com/PromptRepository/resources/YesNo/\">YesNo</a>\"</tt> prompt as a function prompt:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg72_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg72.png' alt='' title='' width='425' height='43'> </div>\n</p></div>\n<p>And in general, as we’ll discuss later, there’s actually lots of crossover between what we’ve called “function”, “persona” and “modifier” prompts.</p>\n<p>The Wolfram Prompt Repository is intended to have lots of good, useful prompts in it, and to provide a curated, public collection of prompts. But sometimes you’ll want your own, custom prompts—that you might want to share, either publicly or with a specific group. And—just as with the <a href=\"https://resources.wolframcloud.com/FunctionRepository\">Wolfram Function Repository</a>, <a href=\"https://datarepository.wolframcloud.com/\" target=\"_blank\" rel=\"noopener\">Wolfram Data Repository</a>, etc.—you can use exactly the same underlying machinery as the Wolfram Prompt Repository to do this. </p>\n<p>Start by bringing up a new Prompt Resource Definition notebook (use the <span class=\"computer-voice\">New</span> > <span class=\"computer-voice\">Repository Item</span> > <span class=\"computer-voice\">Prompt Repository Item</span> menu item). Then fill this out with whatever definition you want to give:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/05/wolfify.png' alt='Wolfify definition notebook' title='Wolfify definition notebook' width='600' height='374'/></p>\n<p>There’s a button to submit your definition to the public Prompt Repository. But instead of using this, you can go to the <span class=\"computer-voice\">Deploy</span> menu, which lets you deploy your definition either locally, or publicly or privately <a href=\"https://www.wolframcloud.com/\">to the cloud</a> (or just within the current Wolfram Language session).</p>\n<p>Let’s say you deploy publicly to the cloud. Then you’ll get a “documentation” webpage:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/05/wolfdoc.png' alt='Wolfify documentatin page' title='Wolfify documentation page' width='485' height='344'/></p>\n<p>And to use your prompt, anyone just has to give its URL:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg75B_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg75A.png' alt='' title='' width='578' height='95'> </div>\n</p></div>\n<p><a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a> gives you a representation of the prompt you wrote:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg76C_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg76A-1.png' alt='' title='' width='630' height='28'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg76B.png' alt='' title='' width='300' height='54'></div>\n</p></div>\n<h2 id=\"how-it-all-works\">How It All Works</h2>\n<p>We’ve seen how <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a>, etc. can be used. But now let’s talk about how they work at an underlying Wolfram Language level. Like everything else in Wolfram Language, <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a>, etc. are symbolic objects. Here’s a simple <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223upwardimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223upwardimg1.png' alt='' title='' width='317' height='84'> </div>\n</p></div>\n<p>And when we apply the <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, we’re taking this symbolic object and supplying some argument to it—and then it’s evaluating to give a result:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223upwardimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223upwardimg2.png' alt='' title='' width='441' height='81'> </div>\n</p></div>\n<p>But what’s actually going on underneath? There are two basic steps. First a piece of text is created. And then this text is fed to the LLM—which generates the result which is returned. So how is the text created? Essentially it’s through the application of a standard <a href=\"https://reference.wolfram.com/language/ref/StringTemplate.html\">Wolfram Language string template</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg80_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg80.png' alt='' title='' width='395' height='46'> </div>\n</p></div>\n<p>And then comes the “big step”—processing this text through the LLM. And this is achieved by <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg81_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg81.png' alt='' title='' width='339' height='45'> </div>\n</p></div>\n<p><a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a> is the function that ultimately underlies all our LLM functionality. Its goal is to do <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#its-just-adding-one-word-at-a-time\">what LLMs fundamentally do</a>—which is to take a piece of text and “continue it in a reasonable way”. Here’s a very simple example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg82_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg82.png' alt='' title='' width='306' height='43'> </div>\n</p></div>\n<p>When you do something like ask a question, <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a> will “continue” by answering it, potentially with another sentence:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg83_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg83.png' alt='' title='' width='433' height='45'> </div>\n</p></div>\n<p>There are lots of details, that we’ll talk about later. But we’ve now seen the basic setup, at least for generating textual output. But another important piece is being able to “interpret” the textual output as a computable Wolfram Language expression that can immediately plug into all the other capabilities of the Wolfram Language. The way this interpretation is specified is again very straightforward: you just give a second argument to the <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>.</p>\n<p>If that second argument is, say, <tt>f</tt>, the result you’ll get just has <tt>f</tt> applied to the textual output:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg84_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg84.png' alt='' title='' width='390' height='45'> </div>\n</p></div>\n<p>But what’s actually going on is that <tt><a href=\"http://reference.wolfram.com/language/ref/Interpreter.html\">Interpreter</a></tt><tt>[f]1</tt> is being applied, which for the symbol <tt>f</tt> happens to be the same as just applying <tt>f</tt>. But in general <tt><a href=\"http://reference.wolfram.com/language/ref/Interpreter.html\">Interpreter</a></tt> is what provides access to the powerful <a href=\"https://www.wolfram.com/natural-language-understanding/\">natural language understanding capabilities</a> of the Wolfram Language—that allow you to convert from pure text to computable Wolfram Language expressions. Here are a few examples of <tt><a href=\"http://reference.wolfram.com/language/ref/Interpreter.html\">Interpreter</a></tt> in action:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg85_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg85.png' alt='' title='' width='251' height='45'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg86_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg86.png' alt='' title='' width='441' height='57'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg87_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg87.png' alt='' title='' width='551' height='59'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg88_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg88.png' alt='' title='' width='405' height='45'> </div>\n</p></div>\n<p>So now, by including a <tt>\"Color\"</tt> interpreter, we can make <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> return an actual symbolic color specification:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg89_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg89.png' alt='' title='' width='395' height='45'> </div>\n</p></div>\n<p>Here’s an example where we’re telling the LLM to write <a href=\"https://reference.wolfram.com/language/ref/format/JSON.html\">JSON, then interpreting it</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg90_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg90.png' alt='' title='' width='702' height='69'> </div>\n</p></div>\n<p>A lot of the operation of <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> “comes for free” from the way <a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/42-string-patterns-and-templates.html\">string templates work in the Wolfram Language</a>.

And for consistency, all prompts from the Prompt Repository are given in the form of template objects. </p>\n<p>If there are no parameters, here’s how you can extract the pure text form of an <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg99_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg99.png' alt='' title='' width='397' height='45'> </div>\n</p></div>\n<p><a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a> effectively automatically resolves any <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a> templates given in it, so for example this immediately works:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg100_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg100.png' alt='' title='' width='495' height='70'> </div>\n</p></div>\n<p>And it’s this same mechanism that lets one include <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a> objects inside <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, etc. </p>\n<p>By the way, there’s always a “core template” in any <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>.

When the prompts don’t have parameters this is straightforward, and you can just give all the prompts you want directly in a list.</p>\n<p>But when prompts have parameters, things are a bit more complicated. Here’s an example that uses two prompts, one of which has a parameter:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg103_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg103.png' alt='' title='' width='588' height='115'> </div>\n</p></div>\n<p>And the point is that by using <tt><a href=\"http://reference.wolfram.com/language/ref/TemplateSlot.html\">TemplateSlot</a></tt> we can “pull in” arguments from the “outer” <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, and use them to explicitly fill arguments we need for an <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a> inside. And of course it’s very convenient that we can use general Wolfram Language <tt><a href=\"http://reference.wolfram.com/language/ref/TemplateObject.html\">TemplateObject</a></tt> technology to specify all this “plumbing”.</p>\n<p>But there’s actually even more that <tt><a href=\"http://reference.wolfram.com/language/ref/TemplateObject.html\">TemplateObject</a></tt> technology gives us. One issue is that in order to feed something to an LLM (or, at least, a present-day one), it has to be an ordinary text string. Yet it’s often convenient to give general Wolfram Language expression arguments to LLM functions. Inside <tt><a href=\"http://reference.wolfram.com/language/ref/StringTemplate.html\">StringTemplate</a></tt> (and <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>) there’s an <tt><a href=\"http://reference.wolfram.com/language/ref/InsertionFunction.html\">InsertionFunction</a></tt> option, that specifies how things are supposed to be converted for insertion—and the default for that is to use the function <tt><a href=\"http://reference.wolfram.com/language/ref/TextString.html\">TextString</a></tt>, which tries to make “reasonable textual versions” of any Wolfram Language expression.</p>\n<p>So this is why something like this can work:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg104_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg104.png' alt='' title='' width='373' height='46'> </div>\n</p></div>\n<p>It’s because applying the <tt><a href=\"https://reference.wolfram.com/language/ref/StringTemplate.html\">StringTemplate</a></tt> turns the <img style=\"margin-bottom: -2px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223pinkbox.png' alt='' title='' width='15' height='15'> expression into a string (in this case <tt><a href=\"https://reference.wolfram.com/language/ref/RGBColor.html\">RGBColor</a>[</tt>…<tt>]</tt>) that the LLM can process.</p>\n<p>It’s always possible to specify your own <tt><a href=\"http://reference.wolfram.com/language/ref/InsertionFunction.html\">InsertionFunction</a></tt>.

But what about the LLM inside? What specifies how it’s set up? </p>\n<p>The key is to think of it as being what we’re calling an “LLM evaluator”. In using Wolfram Language the default is to evaluate expressions (like 2 + 2) using the standard Wolfram Language evaluator. Of course, there are functions like <tt><a href=\"http://reference.wolfram.com/language/ref/CloudEvaluate.html\">CloudEvaluate</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/RemoteEvaluate.html\">RemoteEvaluate</a></tt>—as well as <tt><a href=\"http://reference.wolfram.com/language/ref/ExternalEvaluate.html\">ExternalEvaluate</a></tt>—that do evaluation”elsewhere”. And it’s basically the same story for LLM functions. Except that now the “evaluator” is an LLM, and “evaluation” means running the LLM, ultimately in effect using <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a>.</p>\n<p>And the point is that you can specify what LLM—with what configuration—should be used by setting the <a href=\"https://reference.wolfram.com/language/ref/LLMEvaluator.html\"><tt>LLMEvaluator</tt></a> option for <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a>, <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, etc. You can also give a default by setting the global value of <a href=\"https://reference.wolfram.com/language/ref/$LLMEvaluator.html\"><tt>$LLMEvaluator</tt></a>.</p>\n<p>Two basic choices of underlying model right now are <tt>\"<a href=\"https://platform.openai.com/docs/models/gpt-3-5\" target=\"_blank\">GPT-3.5-Turbo</a>\"</tt>, <tt>\"<a href=\"https://platform.openai.com/docs/models/gpt-4\" target=\"_blank\">GPT-4</a>\"</tt> (as well as <a href=\"https://platform.openai.com/docs/models\" target=\"_blank\">other OpenAI models</a>)—and there’ll be more in the future.

There are various options to support this. One is <tt>\"StopTokens\"</tt>—a list of tokens which, if encountered, should cause the LLM to stop generating output, here at the “ff” in the word “giraffe”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg109_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg109.png' alt='' title='' width='411' height='70'> </div>\n</p></div>\n<p><tt>LLMConfiguration</tt> lets you specify a full “symbolic LLM configuration” that precisely defines what LLM, with what configuration, you want to use:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg110_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg110.png' alt='' title='' width='594' height='103'> </div>\n</p></div>\n<p>There’s one particularly important further aspect of LLM configurations to discuss, and that’s the question of how much randomness the LLM should use. The most common way to specify this is through the <tt>\"Temperature\"</tt> parameter. Recall that at each step in its operation an <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#its-just-adding-one-word-at-a-time\">LLM generates a list of probabilities</a> for what the next token in its output should be. The <tt>\"Temperature\"</tt> parameter <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#its-just-adding-one-word-at-a-time\">determines how to actually generate a token</a> based on those probabilities.</p>\n<p>Temperature 0 always “deterministically” picks the token that is deemed most probable. Nonzero temperatures explicitly introduce randomness. Temperature 1 picks tokens according to the actual probabilities generated by the LLM. Lower temperatures favor words that were assigned higher probabilities; higher temperature “reach further” to words with lower probabilities.</p>\n<p>Lower temperatures generally lead to “flatter” but more reliable and reproducible results; higher temperatures introduce more “liveliness”, but also more of a tendency to “go off track”.</p>\n<p>Here’s what happens at zero temperature (yes, a very “flat” joke):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg111_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg111.png' alt='' title='' width='579' height='45'> </div>\n</p></div>\n<p>Now here’s temperature 1:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg112_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg112.png' alt='' title='' width='579' height='45'> </div>\n</p></div>\n<p>There’s always randomness at temperature 1, so the result will typically be different every time:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg113_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg113.png' alt='' title='' width='579' height='66'> </div>\n</p></div>\n<p>If you increase the temperature too much, the LLM will start “melting down”, and producing nonsense:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg114_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg114.png' alt='' title='' width='592' height='66'> </div>\n</p></div>\n<p>At temperature 2 (the current maximum) the LLM has effectively gone completely bonkers, dredging up all sorts of weird stuff from its “subconscious”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg115_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/llmsynthesize.png' alt='' title='' width='620' height='252'> </div>\n</p></div>\n<p>In this case, it goes on for a long time, but finally hits a stop token and stops. But often at higher temperatures you’ll have to explicitly specify the <tt><a href=\"http://reference.wolfram.com/language/ref/MaxItems.html\">MaxItems</a></tt> option for <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a>, so you cut off the LLM after a given number of tokens—and don’t let it “randomly wander” forever.</p>\n<p>Now here comes a subtlety. While by default <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> uses temperature 0, <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a> instead uses temperature 1. And this nonzero temperature means that <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a> will by default typically generate different results every time it’s used:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg116_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg116.png' alt='' title='' width='320' height='45'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg117_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg117.png' alt='' title='' width='556' height='45'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg118_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg118.png' alt='' title='' width='539' height='45'> </div>\n</p></div>\n<p>So what about <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>? It’s set up to be by default as “deterministic” and repeatable as possible. But for subtle and detailed reasons it can’t be perfectly deterministic and repeatable, at least with typical current implementations of LLM neural nets. </p>\n<p>The basic issue is that current neural nets <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#neural-nets\">operate with approximate real numbers</a>, and occasionally roundoff in those numbers can be critical to “decisions” made by the neural net (typically because the application of the activation function for the neural net can lead to a bifurcation between results from numerically nearby values). And so, for example, if different <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> evaluations happen on servers with different hardware and different roundoff characteristics, the results can be different.</p>\n<p>But actually the results can be different even if exactly the same hardware is used. Here’s the typical (subtle) reason why. In a neural net evaluation there are lots of arithmetic operations that can in principle be done in parallel. And if one’s using a GPU there’ll be units that can in principle do certain numbers of these operations in parallel. But there’s typically elaborate <a href=\"https://docs.nvidia.com/cuda/archive/11.8.0/floating-point/index.html\" target=\"_blank\" rel=\"noopener\">real-time optimization of what operation should be done when</a>—that depends, for example, on the detailed state and history of the GPU. But so what? Well, it means that in different cases operations can end up being done in different orders. So, for example, one time one might end up computing (<em>a</em> + <em>b</em>) + <em>c</em>, while another time one might compute <em>a</em> + (<em>b</em> + <em>c</em>).</p>\n<p>Now, of course, in standard mathematics, for ordinary numbers <em>a</em>, <em>b</em> and <em>c</em>, these forms are always identically equal. But with limited-precision floating-point numbers on a computer, they sometimes aren’t, as in a case like this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg119_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg119.png' alt='' title='' width='313' height='46'> </div>\n</p></div>\n<p>And the presence of even this tiny deviation from associativity (normally only in the least significant bit) means that the order of operations in a GPU can in principle matter. At the level of individual operations, it’s a small effect. But if one “hits a bifurcation” in the neural net, there can end up being a cascade of consequences, leading eventually to a different token being produced, and a whole different “path of text” being generated—all even though one is “operating at zero temperature”. </p>\n<p>Most of the time this is quite a nuisance—because it means you can’t count on an <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> doing the same thing every time it’s run. But sometimes you’ll specifically want an <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> to be a bit random and “creative”—which is something you can force by explicitly telling it to use a nonzero temperature. So, for example, with default zero temperature, this will usually give the same result each time:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg120_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg120.png' alt='' title='' width='556' height='46'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg121_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg121.png' alt='' title='' width='556' height='46'> </div>\n</p></div>\n<p>But with temperature 1, you’ll get different results each time (though the LLM really seems to like Sally!):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg122_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg122.png' alt='' title='' width='484' height='94'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg123_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg123.png' alt='' title='' width='459' height='70'> </div>\n</p></div>\n<h2 id=\"ai-wrangling-and-the-art-of-prompts\">AI Wrangling and the Art of Prompts</h2>\n<p>There’s a certain systematic and predictable character to writing typical Wolfram Language. You use functions that have been carefully designed (with <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\" target=\"_blank\" rel=\"noopener\">great effort</a>, over decades, I might add) to do particular, well-specified and documented things. But setting up prompts for LLMs is a much less systematic and predictable activity. It’s more of an art—where one’s effectively probing the “alien mind” of the LLM, and trying to “wrangle” it to do what one wants.</p>\n<p>I’ve come to believe, though, that the #1 thing about good prompts is that they have to be based on good expository writing. The same things that make a piece of writing understandable to a human will make it “understandable” to the LLM. And in a sense that’s not surprising, given that the LLM is trained in a very “human way”—from human-written text. </p>\n<p>Consider the following prompt:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg124_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg124.png' alt='' title='' width='374' height='45'> </div>\n</p></div>\n<p>In this case it does what one probably wants. But it’s a bit sloppy. What does “reverse” mean? Here it interprets it quite differently (as character string reversal):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg125_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg125.png' alt='' title='' width='333' height='46'> </div>\n</p></div>\n<p>Better wording might be:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg126_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg126.png' alt='' title='' width='382' height='45'> </div>\n</p></div>\n<p>But one feature of an LLM is that whatever input you give, it’ll always give some output. It’s not really clear what the “opposite” of a fish is—but the LLM offers an opinion:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg127_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg127.png' alt='' title='' width='327' height='45'> </div>\n</p></div>\n<p>But whereas in the cases above the <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> just gave single-word outputs, here it’s now giving a whole explanatory sentence. And one of the typical challenges of <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> prompts is trying to be sure that they give results that stay in the same format. Quite often telling the LLM what format one wants will work (yes, it’s a slightly dubious “opposite”, but not completely crazy):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg128_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg128.png' alt='' title='' width='524' height='44'> </div>\n</p></div>\n<p>Here we’re trying to constrain the output more—which in this case worked, though the actual result was different:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg129_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg129.png' alt='' title='' width='606' height='92'> </div>\n</p></div>\n<p>It’s often useful to give the LLM examples of what you want the output to be like (the <tt>\\n</tt> newline helps separate parts of the prompt):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg130_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg130.png' alt='' title='' width='543' height='44'> </div>\n</p></div>\n<p>But even when you think you know what’s going to happen, the LLM can sometimes surprise you. This finds phonetic renditions of words in different forms of English: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg131_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg131.png' alt='' title='' width='531' height='45'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg132_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg132.png' alt='' title='' width='550' height='45'> </div>\n</p></div>\n<p>So far, consistent formats. But now look at this (!):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg133_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg133.png' alt='' title='' width='510' height='46'> </div>\n</p></div>\n<p>If you give an interpretation function inside <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, this can often in effect “clean up” the raw text generated by the LLM. But again things can go wrong. Here’s an example where many of the colors were successfully interpreted, but one didn’t make it:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg134_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg134.png' alt='' title='' width='650' height='106'> </div>\n</p></div>\n<p>(The offending “color” is “neon”, which is really more like a class of colors.)</p>\n<p>By the way, the general form of the result we just got is somewhat remarkable, and characteristic of an interesting capability of LLMs—effectively their ability to do “linguistic statistics” of the web, etc. Most likely the LLM never specifically saw in its training data a table of “most fashionable colors”. But it saw lots of text about colors and fashions, that mentioned particular years. If it had collected numerical data, it could have used standard mathematical and statistical methods to combine it, look for “favorites”, etc. But instead it’s dealing with linguistic data, and the point is that the way an LLM works, it’s in effect able to systematically handle and combine that data, and derive “aggregated conclusions” from it.</p>\n<h2 id=\"symbolic-chats\">Symbolic Chats</h2>\n<p>In <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, etc. the underlying LLM is basically always called just once. But in a chatbot like <a href=\"https://chat.openai.com/\" target=\"_blank\" rel=\"noopener\">ChatGPT</a> things are different: there the goal is to build up a chat, with the LLM being called repeatedly, as things go back and forth with a (typically human) “chat partner”. And along with the release of <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a>, etc. we’re also releasing a symbolic framework for “LLM chats”.</p>\n<p>A chat is always represented by a chat object. This creates an “empty chat”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg135_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg135C.png' alt='' title='' width='195' height='80'> </div>\n</p></div>\n<p>Now we can take the empty chat, and “make our first statement”, to which the LLM will respond:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg136_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg136.png' alt='' title='' width='545' height='148'> </div>\n</p></div>\n<p>We can add another back and forth:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg137_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg137.png' alt='' title='' width='678' height='313'> </div>\n</p></div>\n<p>At each stage the <a href=\"https://reference.wolfram.com/language/ref/ChatObject.html\"><tt>ChatObject</tt></a> represents the complete state of the chat so far. So it’s easy for us to go back to a given state, and “go on differently” from there:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg138_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg138.png' alt='' title='' width='678' height='314'> </div>\n</p></div>\n<p>What’s inside a <a href=\"https://reference.wolfram.com/language/ref/ChatObject.html\"><tt>ChatObject</tt></a>? Here’s the basic structure:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg139_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg139A.png' alt='' title='' width='721' height='228'> </div>\n</p></div>\n<p>The “roles” are defined by the underlying LLM; in this case they’re “User” (i.e. content provided by the user) and “Assistant” (i.e. content generated automatically by the LLM).</p>\n<p>When an LLM generates new output in chat, it’s always reading everything that came before in the chat. <a href=\"https://reference.wolfram.com/language/ref/ChatObject.html\"><tt>ChatObject</tt></a> has a convenient way to find out how big a chat has got:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg140_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg140.png' alt='' title='' width='155' height='57'> </div>\n</p></div>\n<p><a href=\"https://reference.wolfram.com/language/ref/ChatObject.html\"><tt>ChatObject</tt></a> typically displays as a chat history. But you can create a <a href=\"https://reference.wolfram.com/language/ref/ChatObject.html\"><tt>ChatObject</tt></a> by giving the explicit messages you want to appear in the initial chat—here based on one part of the history above—and then run <tt>ChatEvaluate</tt> starting from that:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg141_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg141.png' alt='' title='' width='678' height='553'> </div>\n</p></div>\n<p>What if you want to have the LLM “adopt a particular persona”? Well, you can do that by giving an initial (<tt>\"System\"</tt>) prompt, say from the <a href=\"https://resources.wolframcloud.com/PromptRepository/\">Wolfram Prompt Repository</a>, as part of an <a href=\"https://reference.wolfram.com/language/ref/LLMEvaluator.html\"><tt>LLMEvaluator</tt></a> specification:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223yodaimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223yodaimg1.png' alt='' title='' width='678' height='362'> </div>\n</p></div>\n<p>Having chats in symbolic form makes it possible to build and manipulate them programmatically. Here’s a small program that effectively has the AI “interrogate itself”, automatically switching back and forth being the “User” and “Assistant” sides of the conversation:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg143_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223interrogation1.png' alt='' title='' width='550' height='216'> </br> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223interrogation2A.png' alt='' title='' width='675' height='482'></div>\n</p></div>\n<h2 id=\"this-is-just-the-beginning\">This Is Just the Beginning…</h2>\n<p>There’s a lot that can be done with all the new functionality we’ve discussed here. But actually it’s just part of what we’ve been able to develop by combining our longtime tower of technology with newly available LLM capabilities. I’ll be describing more in subsequent posts.</p>\n<p>But what we’ve seen here is essentially the “call an LLM from within Wolfram Language” side of things. In the future, we’ll discuss how Wolfram Language tools can be called from within an LLM—opening up very powerful multi-pass automatic “collaboration” between LLMs and Wolfram Language. We’ll also in the future discuss how a new kind of Wolfram Notebooks can be used to provide a uniquely effective interactive interface to LLMs. And there’ll be much more too. Indeed, almost every day we’re uncovering remarkable new possibilities. </p>\n<p>But <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> and the other things we’ve discussed here form an important foundation for what we can now do. Extending what we’ve done over the past decade or more in machine learning, they form a key bridge between the symbolic world that’s at the core of the Wolfram Language, and the “statistical AI” world of LLMs. It’s a uniquely powerful combination that we can expect to represent an anchor piece of what can now be done.</p>\n",

Elle permet l'utilisation de fonctions telles que la génération de texte et la traduction. L'installation se fait via `pip install litellm`, et son utilisation nécessite de définir des variables d'environnement et de créer un objet LiteLLM. LiteLLM supporte également un proxy pour rediriger les requêtes vers le modèle souhaité et offre des fonctionnalités supplémentaires comme le streaming, la gestion des exceptions, et le suivi des coûts. Plus d'informations sont disponibles sur la page GitHub de LiteLLM.",

Elle fournit une interface simple et uniformisée pour appeler ces modèles , ce qui va vous faciliter leur utilisation pour des choses comme de la génération de texte, de la traduction ou encore du chat…</p>\n\n\n\n<p>Pour l’installer, rien de plus simple : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>pip install litellm</code></pre>\n\n\n\n<p>Ensuite, y’a plus qu’à créer un objet LiteLLM dans votre code, en lui fournissant l’ID et le nom du modèle à utiliser. Par exemple pour vous connecter à OpenAI, le code sera le suivant : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>from litellm import completion\nimport os\n\n## set ENV variables\nos.environ[\"OPENAI_API_KEY\"] = \"your-api-key\"\n\nresponse = completion(\n model=\"gpt-3.5-turbo\", \n messages=[{ \"content\": \"Hello, how are you?\",\"role\": \"user\"}]\n)</code></pre>\n\n\n\n<p>Pour Claude 2, ça sera ça : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>from litellm import completion\nimport os\n\n## set ENV variables\nos.environ[\"ANTHROPIC_API_KEY\"] = \"your-api-key\"\n\nresponse = completion(\n model=\"claude-2\", \n messages=[{ \"content\": \"Hello, how are you?\",\"role\": \"user\"}]\n)</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1244015948\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Pour utiliser <a href=\"https://www.youtube.com/watch?app=desktop&v=1aXPuFrPtr0\" target=\"_blank\" rel=\"noopener\">Ollama</a>, ça donnerait également ça : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>from litellm import completion\n\nresponse = completion(\n model=\"ollama/llama2\", \n messages = [{ \"content\": \"Hello, how are you?\",\"role\": \"user\"}], \n api_base=\"http://localhost:11434\"\n)</code></pre>\n\n\n\n<p>Donc pas grand-chose qui change. </p>\n\n\n\n<p>Vous l’aurez donc compris, LiteLLM permet de pondre un seul et unique code, mais pour discuter avec tous les fournisseurs d’IA du moment (et les logiciels libres existants)</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"653\" height=\"1024\" src=\"https://korben.info/app/uploads/2024/01/SCR-20240115-ln9-653x1024.webp\" alt=\"\" class=\"wp-image-156049\" srcset=\"https://korben.info/app/uploads/2024/01/SCR-20240115-ln9-653x1024.webp 653w, https://korben.info/app/uploads/2024/01/SCR-20240115-ln9-191x300.webp 191w, https://korben.info/app/uploads/2024/01/SCR-20240115-ln9-768x1205.webp 768w, https://korben.info/app/uploads/2024/01/SCR-20240115-ln9.webp 928w\" sizes=\"(max-width: 653px) 100vw, 653px\" /></figure></div>\n\n\n<p>Y’a la possibilité d’avoir du stream sur les réponses (c’est à dire, le texte qui s’affiche au fur et à mesure), de la gestion des exceptions, du log, sans oublier du calcul de coût et l’usage que vous pouvez avoir de ces API afin de ne pas éclater votre compte en banque.</p>\n\n\n\n<p>LiteLLM intègre également un proxy OpenAI pour rediriger vos requêtes vers le modèle de votre choix. Pour l’installer : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>pip install 'litellm[proxy]'</code></pre>\n\n\n\n<p>Lancez ensuite le proxy avec le modèle de votre choix :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>litellm --model huggingface/bigcode/starcoder</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-259844503\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Et lui passer vos requêtes dans le code python directement : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>import openai # openai v1.0.0+\nclient = openai.OpenAI(api_key=\"anything\",base_url=\"http://0.0.0.0:8000\") # set proxy to base_url\n# request sent to model set on litellm proxy, `litellm --model`\nresponse = client.chat.completions.create(model=\"gpt-3.5-turbo\", messages = [\n {\n \"role\": \"user\",\n \"content\": \"this is a test request, write a short poem\"\n }\n])\n\nprint(response)</code></pre>\n\n\n\n<p>Si LiteLLM vous intéresse, vous trouverez toutes les infos <a href=\"https://github.com/BerriAI/litellm\" target=\"_blank\" rel=\"noopener\">sur la page Github</a> ainsi que les <a href=\"https://litellm-api.up.railway.app/\" target=\"_blank\" rel=\"noopener\">endpoints ici</a>.</p>\n",

Si vous aimez les jeux de mots et le pain, vous allez être servi !</p>\n\n\n\n<p>Sur le plan artistique, c’est vraiment cool : graphismes léchés, un mélange 2D/3D de toute beauté (même si ça n’a aucun sens d’avoir des personnages plats, contrairement à Paper Mario), de belles animations, de chouettes musiques, des cinématiques bien foutues, on est vite immergé dans cet univers absurde.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2024/02/Born-of-Bread-4.webp\" alt=\"\" class=\"wp-image-156332\" srcset=\"https://korben.info/app/uploads/2024/02/Born-of-Bread-4.webp 1000w, https://korben.info/app/uploads/2024/02/Born-of-Bread-4-300x169.webp 300w, https://korben.info/app/uploads/2024/02/Born-of-Bread-4-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Pour les connaisseurs, le gameplay ne propose rien de nouveau (hormis quelques délires à base de « spectateurs » lors de nos bastons) mais c’est une recette (miam) efficace et éprouvée, ça fonctionne vraiment très bien. En dehors de quelques énigmes un peu bizarres, les dialogues et affrontements s’enchaînent de manière fluide, le scénario est bien rythmé, c’est top !</p>\n\n\n\n<p>J’ai été embêté par quelques bugs et plantages, il faut espérer que les développeurs sortent un patch pour que ce soit parfait. 🤞 L’autre truc « un peu » gênant, c’est que finalement, le jeu reste en-dessous de ses modèles. Pour être honnête, si vous avez une Switch, j’aurais tendance à vous conseiller de choper <a href=\"https://korben.info/test-avis-super-mario-rpg-switch.html\">Super Mario RPG</a> ou d’attendre le remake de <a href=\"https://www.youtube.com/watch?v=sVCFBZl_RE4\" target=\"_blank\" rel=\"noopener\">Paper Mario : La Porte Millénaire</a>.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2024/02/Born-of-Bread-1.webp\" alt=\"\" class=\"wp-image-156333\" srcset=\"https://korben.info/app/uploads/2024/02/Born-of-Bread-1.webp 1000w, https://korben.info/app/uploads/2024/02/Born-of-Bread-1-300x169.webp 300w, https://korben.info/app/uploads/2024/02/Born-of-Bread-1-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-25926182\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Mais si vous n’avez pas de console Nintendo, alors <a href=\"https://dearvillagers.com/project/born-of-bread/\" target=\"_blank\" rel=\"noopener\">Born of Bread</a> est un très bon paliatif, une aventure qui se mange sans faim !

Voici un exemple de lancement de l’animation par défaut :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>confetti();</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-994311815\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Et voici un exemple de lancement de l’animation avec des options personnalisées :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>confetti({\n particleCount: 150, // Nombre de confetti à lancer\n spread: 180, // Angle maximal de dispersion des confettis\n startVelocity: 30, // Vitesse initiale des confettis\n origin: {\n x: Math.random(), // Position initiale aléatoire des confettis sur l'axe horizontal\n y: Math.random() - 0.2 // Position initiale légèrement plus élevée sur l'axe vertical\n },\n colors: ['#ff0000', '#00ff00', '#0000ff'], // Couleurs des confettis\n shapes: ['square', 'circle', 'star'], // Formes des confettis\n scalar: 2 // Taille des confettis\n});</code></pre>\n\n\n\n<p>Pour réinitialiser l’animation du confetti et effacer tous les confettis en cours d’animation, utilisez la méthode <code class=\"\">confetti.reset()</code> :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>confetti.reset();</code></pre>\n\n\n\n<p>Si vous souhaitez limiter l’espace sur votre page où les confettis apparaissent, vous pouvez utiliser un canvas personnalisé. Pour cela, créez un élément <code class=\"\"><canvas></code> dans votre HTML et appelez la fonction <code class=\"\">confetti.create()</code> en lui passant l’élément <code class=\"\"><canvas></code> et des options globales facultatives :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>const canvas = document.createElement('canvas');\ndocument.body.appendChild(canvas);\n\nconst myConfetti = confetti.create(canvas, { // Options globales facultatives\n resize: true, // Permet de redimensionner le canvas en fonction de la fenêtre\n useWorker: true // Utilise un web worker pour le rendu du confetti\n});\n\nmyConfetti({ // Options personnalisées\n particleCount: 100,\n spread: 160\n // Autres options personnalisées\n});</code></pre>\n\n\n\n<p>Enfin, si vous souhaitez créer des confettis personnalisés à partir d’une forme SVG ou d’un texte, utilisez les méthodes <code class=\"\">confetti.shapeFromPath</code> et <code class=\"\">confetti.shapeFromText</code> :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>const pathShape = confetti.shapeFromPath({ path: 'M0 10 L5 0 L10 10z' }); // Forme SVG\n\nconst textShape = confetti.shapeFromText({ text: '🐈', scalar: 2 }); // Texte personnalisé\n\nconfetti({\n shapes: [pathShape, textShape],\n scalar: 2\n});</code></pre>\n\n\n\n<p>Le mieux reste d’aller faire un tour sur <a href=\"https://www.kirilv.com/canvas-confetti/\" target=\"_blank\" rel=\"noopener\">la page de démo qui comporte également des exemples d’intégration</a>.</p>\n",

Exolegend, initié par Exotec, est un hackathon de programmation robotique qui se tiendra du 16 au 18 février à Lille, au BTWIN Village. </p>\n\n\n\n<p>Vous vous en doutez, ce n’est pas un simple événement, mais une expérience immersive où les participants vont devoir relever le défi de programmer des robots qui devront évoluer dans un labyrinthe et combattre leurs pairs.</p>\n\n\n\n<p>Pour la petite histoire, Exotec est une société qui conçoit des systèmes automatisés pour les usines et les entrepôts. Ils développent notamment le <strong>Skypod</strong>, un robot qui permet aux entreprises d’automatiser toute la gestion logistique dans leurs entrepôts. </p>\n\n\n\n<p>Ce robot, déjà adopté par Décathlon, Carrefour, Geodis…etc, est capable de transporter jusqu’à 30kg de marchandises en vue de préparer des commandes, atteignant des vitesses allant jusqu’à 4 mètres par seconde et accédant à n’importe quelle produit référencé en moins de 2 minutes. Il est également très agile et capable de se déplacer en trois dimensions (oui, il grimpe jusqu’à 12 mètres de haut) sans nécessiter la mise en place d’infrastructure complexe.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"EXOLEGEND - Plongez au cœur de la robotique avec le hackathon d'Exotec\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/j9_w3orTxNU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>L’objectif d’Exolegend est de faire connaitre leur savoir faire mais également recruter les ingénieurs les plus talentueux. Le programme de cette édition 2024 est plutôt captivant, vous allez voir. Les participants à ce hackathon n’ont pas besoin d’être déjà experts en robotique et auront à leur disposition un simulateur ainsi que des robots prêts à l’emploi. Et leur défi sera de programmer ces robots en C++ pour relever différentes missions dans les thématiques suivantes :</p>\n\n\n\n<ol>\n<li><strong>Conquête de territoire</strong> : Les participants devront utiliser 2 robots pour recouvrir le maximum de cases de l’arène avec de la peinture jaune ou bleue.</li>\n\n\n\n<li><strong>Navigation et stratégie</strong> : Dans celle-ci, il s’agit de guider les robots à travers l’arène, en évitant les obstacles et en déployant des tactiques efficaces pour dominer au maximum l’espace.</li>\n\n\n\n<li><strong>Défense et attaque</strong> : Les équipes devront protéger leurs propres robots tout en attaquant les adversaires, notamment en faisant exploser le ballon accroché sur les robots.</li>\n\n\n\n<li><strong>Temps limité et terrain rétrécissant</strong> : Les matchs durent 120 secondes, et le labyrinthe rétrécit régulièrement. Le but est de gagner en couvrant le plus grand territoire et en éliminant le plus grand nombre d’ennemis.</li>\n</ol>\n\n\n\n<p>L’événement rassemblera 50 équipes, guidées par 60 experts d’Exotec, prêtes à concourir dans une arène simulée et quatre arènes réelles. Les meilleurs participants se verront récompensés par des prix attractifs, notamment du coaching et des drones de la marque DJI.</p>\n\n\n\n<p>Ce hackathon est ouvert à tous, que l’on s’inscrive seul ou en équipe, et il ne requiert pas de frais d’inscription. Les inscriptions sont closes cette année avec plus de 150 participants mais le public est le bienvenu au Btwin Village de Lille le dimanche 18 février de 9h à 16h pour assister aux finales et découvrir le pilotage de robots.</p>\n\n\n\n<p>Vous trouverez toutes les informations sur <a href=\"https://www.exolegend.com/\" target=\"_blank\" rel=\"noopener\">Exolegend ici</a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"592\" height=\"837\" src=\"https://kbn.im/exotec\" alt=\"\"/></figure></div>",

Depuis un autre service a pas mal pris d’ampleur dans le même genre, c’est Amazon Prime Video. Je sais que certains d’entre vous l’utilisent et c’est donc l’occasion d’en profiter pour vous faire un petit rappel sur le sujet.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"729\" height=\"91\" src=\"https://kbn.im/ssaprime\" alt=\"Surfshark pour Amazon Prime, un VPN primé\"/></a></figure></div>\n\n\n<p>Comme pour son concurrent vous savez sans doute qu’Amazon Prime Video ne propose pas le même contenu selon le pays dans lequel vous résidez. Du coup si vous partez à l’étranger (travail, vacances …), vous n’êtes pas certain de pouvoir y visionner votre série préférée. C’est quand même moins fun d’être les doigts de pieds en éventail sur une plage sans pouvoir matter vos épisodes favoris parce qu’ils ne sont pas dispo en version française sur place. Je n’imagine même pas le sentiment de loose qui pourrait me prendre si je me rendais compte que les épisodes de Stargate en VF ne sont dispo qu’en anglais. De quoi ruiner mes futures vacances <s>sur une île paradisiaque</s> au fond de mon jardin.</p>\n\n\n\n<p>Mais surtout le VPN est une solution pour éviter qu’Amazon ne puisse pomper toutes vos données personnelles lorsque vous streamez leurs vidéos. En chiffrant vos données (via algorithme AES-256) , Surfshark va les rendre inutilisables par la plateforme ainsi que pour tous les autres sites web que vous visitez. Elle ne recevra plus d’infos sur l’endroit d’ou vous vous connectez vraiment, n’aura plus accès aux cookies de votre navigateur, etc. Et ne pourra plus vous bombarder de publicités (le VPN agit aussi comme un bloqueur pub).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"480\" height=\"271\" src=\"https://media.giphy.com/media/v1.Y2lkPTc5MGI3NjExdDlsc3YwZWl6Z3libm50a2tzaHoyZm9pYzVkbHBkcXprMGQxaHNuYyZlcD12MV9pbnRlcm5hbF9naWZfYnlfaWQmY3Q9Zw/SDcbLM9gbJYZlRQgtI/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>D’autant plus que l’année dernière Prime Video a annoncé que<strong> l’arrivée de la publicité sur son service</strong> se ferait courant 2024 (a priori vers le milieu de l’année dans l’hexagone). « À petite dose » selon leurs dires, mais on sait comment ça se finira. Probablement blindé de spots pour la malbouffe et avec un abonnement supplémentaire de quelques euros pour une expérience propre. Surfshark VPN coutera le même prix, avec en plus les bénéfices sur le respect de votre vie privée. Le calcul est vite fait et ce sera toujours quelques euros d’économies (en plus de celles que vous pouvez faire <a href=\"https://korben.info/surfshark-vpn-expatries.html\" data-type=\"link\" data-id=\"https://korben.info/surfshark-vpn-expatries.html\">sur vos billets, hôtels</a>, etc.) </p>\n\n\n\n<p>Et avec son gros parc de serveurs (+ de 3200, répartit dans plus de 100 pays) qui est en train de passer intégralement de 1 à 10 Gb/s, Surfshark est taillé pour du streaming stable et presque sans ralentissements notables. Si vous avez l’esprit d’aventure, vous pouvez aussi le coupler avec les protocoles Wireguard, OpenVPN ou IPsec/IKEv2.</p>\n\n\n\n<p><a href=\"https://korben.info/lip-fixe-debarque-chez-surfshark.html\" data-type=\"link\" data-id=\"https://korben.info/lip-fixe-debarque-chez-surfshark.html\">Adresse IP fixe</a> ou rotative, bouton kill switch, MultiHop dynamique, mode camouflage, DNS privé, split tunneling, GPS-Spoofing pour Android … Toutes ces fonctionnalités, que j’ai présentées dans mes précédents articles, sont toujours à votre disposition. De même que l’assurance que<strong> vos données ne sont pas enregistrées par Surfshark</strong> (ce qui a été vérifié par plusieurs audits ces derniers mois : Deloitte, Mobile App Security Assessment …).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"301\" src=\"https://korben.info/app/uploads/2024/02/alternative-id.jpg\" alt=\"Alternative ID Surfshark\" class=\"wp-image-156237\" srcset=\"https://korben.info/app/uploads/2024/02/alternative-id.jpg 600w, https://korben.info/app/uploads/2024/02/alternative-id-300x151.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" /></figure></div>\n\n\n<p>Au rayon des petites nouveautés de ce début 2024, sachez que Surfshark vient d’intégrer <a href=\"https://korben.info/surfshark-one-se-dote-de-loption-creation-didentite-alternative-promo-rentree-2023.html\" data-type=\"link\" data-id=\"https://korben.info/surfshark-one-se-dote-de-loption-creation-didentite-alternative-promo-rentree-2023.html\">son outil de création d’identités alternatives</a> dans tous ses packs. Donc même le plus petit abonnement vous offre cette fonctionnalité auparavant réservée à l’offre Surfshark One. Un petit bonus en plus !</p>\n\n\n\n<p>Voilà, vous savez maintenant quel est l’intérêt d’utiliser un VPN avec Amazon Prime Video. Mais cela fonctionne avec n’importe lequel de vos services de streaming préféré, de Disney+ à Hulu en passant par Netflix et Apple TV.</p>\n\n\n\n<p>D’ailleurs si vous pensez enfin sécuriser un peu mieux votre surf sur le web, n’oubliez pas que le service permet de connecter autant d’appareils que vous le voulez (desktop, mobile, console, routeur, Amazon Fire Stick, etc.) et de les utiliser en simultané. Le prix englobe donc vos machines, mais aussi celles de votre famille & co. Quel que soit l’OS utilisé par chacune d’entre elles. Pour moins de 3€/mois !</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" data-type=\"link\" data-id=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Découvrir l’offre de Surfshark VPN</a></h2>\n",

"description": "Depuis des années, les utilisateurs de Windows peuvent sécuriser leurs données avec Bitlocker grâce à la puce TPM. Le chercheur StackSmashing a trouvé comment extraire la clé de chiffrement de cette puce avec un Raspberry Pi Pico bon marché. Cette technique a été démontrée sur des Lenovo Thinkpad, mais elle pourrait s'adapter à d'autres ordinateurs. Les nouveaux processeurs intégrant le TPM rendent cependant l'attaque plus difficile.",

"description": "Shell GPT est un assistant personnel basé sur l'IA pour générer des commandes shell, du code et de la documentation. Il s'installe facilement via pip et nécessite la clé API OpenAI dans le .zshrc ou .bashrc. Avec différentes commandes, il peut exécuter des requêtes, lancer des commandes directes avec du code, initier des sessions de chat pour des interactions longues, et même intégrer des fonctions au shell. Il dispose aussi d'un mode REPL interactif et permet la personnalisation avec des rôles spécifiques.",

Hier on a vu un plugin VS Code pour coder plus rapidement. Et aujourd’hui, je vous propose<a href=\"https://github.com/TheR1D/shell_gpt\" target=\"_blank\" rel=\"noopener\"> Shell GPT</a>, un assistant personnel qui utilise ChatGPT pour vous aider à générer des commandes shell, des bouts de code et même de la documentation.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-822997040\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Pour l’installer, c’est easy : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>pip install shell-gpt</code></pre>\n\n\n\n<p>Il faudra quand même faire un <em>export OPENAI_API_KEY</em>comme d’habitude dans votre .zshrc ou .bashrc pour lui indiquer votre clé API OpenAI. Et redémarrez votre terminal pour que les modifications prennent effet.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>export OPENAI_API_KEY=\"votre_clé_API_OpenAI\"</code></pre>\n\n\n\n<p>Une fois installé, ça fait plein de trucs cool. Vous pouvez simplement exécuter la commande <code class=\"\">sgpt</code> suivie de votre requête pour lui demander tout ce que vous voulez. Par exemple, pour rechercher les couleurs d’un arc-en-ciel, vous pouvez exécuter la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>sgpt \"quelles sont les couleurs d'un arc-en-ciel ?\"\n</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"567\" height=\"62\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lll.png\" alt=\"\" class=\"wp-image-155856\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lll.png 567w, https://korben.info/app/uploads/2023/12/SCR-20231219-lll-300x33.png 300w\" sizes=\"(max-width: 567px) 100vw, 567px\" /></figure></div>\n\n\n<p>Mais vous pouvez surtout lui demander des commandes que vous ne sauriez pas construire. Par exemple : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>sgpt \"VOTRE DEMANDE\"</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"697\" height=\"483\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231219-log.webp\" alt=\"\" class=\"wp-image-155859\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231219-log.webp 697w, https://korben.info/app/uploads/2023/12/SCR-20231219-log-300x208.webp 300w\" sizes=\"(max-width: 697px) 100vw, 697px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1236069707\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Ou pour avoir une réponse plus directe avec uniquement du code, il suffit d’ajouter le paramètre –code : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>sgpt --code \"VOTRE DEMANDE\"</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"697\" height=\"231\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lr0.webp\" alt=\"\" class=\"wp-image-155861\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lr0.webp 697w, https://korben.info/app/uploads/2023/12/SCR-20231219-lr0-300x99.webp 300w\" sizes=\"(max-width: 697px) 100vw, 697px\" /></figure></div>\n\n\n<p>Pour ceux qui veulent, vous pouvez même lancer votre demande en mode shell pour pouvoir l’exécuter de suite : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>sgpt --shell \"VOTRE DEMANDE\"</code></pre>\n\n\n\n<p>Et pour aller encore plus loin, vous pouvez aussi le lancer en mode « chat ». S’engagera alors une discussion sur le long cours, avec possibilité de créer des fichiers, de les modifier, de lancer des commandes, etc… Remplacez NOM_SESSION par le titre à donner à votre chat, pour pouvoir ensuite y retourner en gardant le contexte.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>sgpt --chat NOM_SESSION \"VOTRE DEMANDE\"</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"942\" height=\"592\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lyh-1.webp\" alt=\"\" class=\"wp-image-155863\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lyh-1.webp 942w, https://korben.info/app/uploads/2023/12/SCR-20231219-lyh-1-300x189.webp 300w, https://korben.info/app/uploads/2023/12/SCR-20231219-lyh-1-768x483.webp 768w\" sizes=\"(max-width: 942px) 100vw, 942px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"815\" height=\"412\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lym.webp\" alt=\"\" class=\"wp-image-155864\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231219-lym.webp 815w, https://korben.info/app/uploads/2023/12/SCR-20231219-lym-300x152.webp 300w, https://korben.info/app/uploads/2023/12/SCR-20231219-lym-768x388.webp 768w\" sizes=\"(max-width: 815px) 100vw, 815px\" /></figure></div>\n\n\n<p>ShellGPT offre aussi d’autres fonctionnalités avancées, notamment le <strong>REPL mode</strong> qui permet d’interagir avec ShellGPT dans un mode interactif pour générer du code et exécuter des commandes (en appuyant sur la touche « e »</p>\n\n\n\n<pre class=\"wp-block-code\"><code>sgpt --shell --repl NOM_SESSION</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"909\" height=\"515\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231219-m4c.webp\" alt=\"\" class=\"wp-image-155865\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231219-m4c.webp 909w, https://korben.info/app/uploads/2023/12/SCR-20231219-m4c-300x170.webp 300w, https://korben.info/app/uploads/2023/12/SCR-20231219-m4c-768x435.webp 768w\" sizes=\"(max-width: 909px) 100vw, 909px\" /></figure></div>\n\n\n<p>Et vous pouvez aussi créer des rôles personnalisés pour personnaliser le comportement de ShellGPT dans des scénarios spécifiques, selon vos envies. Je vous invite à vous plonger dans la doc pour exploiter tout ça. Ça fait beaucoup de choses mais c’est super pratique et ça vous aidera à automatiser pas mal de choses.</p>\n\n\n\n<p>Enfin, et je terminerai avec ça, il est possible d’installer une intégration dans votre shell. </p>\n\n\n\n<pre class=\"wp-block-code\"><code>sgpt --install-integration</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1835868426\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>En gros, ça va ajouter quelques lignes dans votre .bashrc ou .zshrc pour simplement en appuyant sur </p>\n\n\n\n<pre class=\"wp-block-code\"><code>CTRL + l</code></pre>\n\n\n\n<p>transformer ce que vous avez écrit dedans en commande exécutable.</p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls src=\"https://korben.info/app/uploads/2023/12/243206128-bead0dab-0dd9-436d-88b7-6abfb2c556c1-2.mp4\"></video></figure>\n\n\n\n<p>Voilà, j’ai à peu pres fait le tour de cet outil merveilleux !</p>\n\n\n\n<p>L’IA c’est cool mais quand c’est bien intégré dans nos outils du quotidien, c’est encore meilleur !</p>\n\n\n\n<p><a href=\"https://github.com/TheR1D/shell_gpt\" target=\"_blank\" rel=\"noopener\">ShellGPT est à découvrir ici.</a></p>\n",

Sans aller jusque là, c’est un outil qui sera aussi assez utile dans certains cas plus classiques. Comme c’est le cas des expatriés qui vont habiter un autre pays.</p>\n\n\n\n<p>Et ici je ne parle pas forcément d’aller dans un pays comme Chine & Co, mais simplement d’aller vivre ailleurs. Dans votre lieu d’origine, vous aviez vos petites habitudes, par exemple pour vous connecter à votre banque ou d’autres services ayant des informations sensibles vous concernant (impôts, mutuelle …). Or, une fois expatrié vous allez peut-être commencer par devoir vous connecter à des wifi-publics, des réseaux moins sécurisés, etc. Surfshark VPN va vous aider à sécuriser vos données (via chiffrement AES-256 et IKEv2/IPse) afin que vos connexions, votre nouveau fournisseur d’accès & co ne puissent pas voir à quoi vous vous connecter et ce que vous faites.</p>\n\n\n\n<p>Un souci récurrent que beaucoup risquent de rencontrer c’est que l’accès à votre compte bancaire à vos données de santé ou divers sites gouvernementaux soit plus difficilement accessible depuis une adresse IP étrangère (voire totalement impossible). En choisissant un serveur situé dans le pays d’origine, le VPN vous aide à éliminer cet obstacle. Et cela peut s’avérer sacrément pratique lorsque vous êtes dans votre nouveau pays et qu’il vous faut demander des documents administratifs à distance.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"480\" height=\"480\" src=\"https://media.giphy.com/media/JQUzRKsg2jF1iJ3gf9/giphy.gif\" alt=\"\" style=\"width:218px;height:auto\"/></figure></div>\n\n\n<p>Il y a donc tout intérêt à opter pour une solution qui possède des serveurs dans un maximum d’endroits du monde. Et qui soient rapides. C’est le cas pour Surfshark puisque ce sont plus de 3200 serveurs, situés dans plus de 100 pays, et dont la plupart ont maintenant des vitesses de 10 Gb/s.</p>\n\n\n\n<p>Autre aspect positif d’un VPN que j’ai déjà abordé : les gains sur les prix des billets d’avion ou de train. Parce qu’en dehors de ceux qui veulent totalement couper les ponts avec leur vie passée, les expats ont souvent le mal du pays au bout d’un moment. Et pouvoir gratter quelques réductions en comparant les prix depuis plusieurs localisations, c’est toujours ça de gagné.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"650\" height=\"341\" src=\"https://kbn.im/surfsharkexpat\" alt=\"Surfshark VPN pour les expatriés\"/></figure></div>\n\n\n<p>Quant à vos films et séries hexagonales préférées vous n’aurez pas besoin de les « binger » avant le départ. Vous garderez l’accès à votre cher Netflix France (ou autres services similaires) depuis votre nouvel emplacement. Vous vous expatriez en famille ? Aucun souci non plus puisque <a href=\"https://get.surfshark.net/aff_c?offer_id=926&aff_id=13768&url_id=1489\" data-type=\"link\" data-id=\"https://get.surfshark.net/aff_c?offer_id=926&aff_id=13768&url_id=1489\" target=\"_blank\" rel=\"noreferrer noopener\">Surfshark VPN</a> vous permet toujours de <strong>connecter un nombre d’appareils illimités (et en simultané) sur un seul compte</strong>. Smartphones, laptop, ordinateur, smartTV et même votre console, ils seront tous couverts. Parmi ses autres fonctionnalités utiles :</p>\n\n\n\n<ul>\n<li>bouton kill switch</li>\n\n\n\n<li>split tunneling</li>\n\n\n\n<li>MultiHop dynamique</li>\n\n\n\n<li>protéger contre le leak DNS</li>\n\n\n\n<li>GPS-Spoofing pour Android</li>\n\n\n\n<li>changement d’IP automatique ou IP dédiée</li>\n\n\n\n<li>…</li>\n</ul>\n\n\n\n<p>Bref pour continuer votre vie numérique avec le moins de perturbations possible, le VPN est une solution qui devrait vous aider. Et vous pouvez en bénéficier pour moins de 2.5€/mois TTC (avec l’abonnement 2 ans). Plutôt honnête pour dormir sur vos 2 oreilles durant cette transition personnelle 😉 Et c’est satisfait ou remboursé durant 30 jours. Au niveau des paiements acceptés vous avez à peu près toutes les options : CB, PayPal, Apple/Amazon/Google Pay et même les cryptomonnaies (maintenant qu’elles se portent mieux, c’est un peu plus intéressant).</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.surfshark.net/aff_c?offer_id=926&aff_id=13768&url_id=1489\" rel=\"noreferrer noopener\" target=\"_blank\">Partez l’esprit tranquille avec Surfshark VPN !</a></h2>\n",

"description": "Alexandre a développé un IDE open source pour les bases de données nommé WebDB, qui facilite l'administration et la gestion des données. Avec une interface intuitive, WebDB permet une découverte aisée des serveurs, une gestion des données simplifiée, et un éditeur de requêtes efficace avec autocomplétion. Il supporte les mises à jour par lots, l'édition de colonnes, les relations SQL, et intègre ChatGPT ainsi que des fonctionnalités d'import/export de données.

J’ai trouvé ça très cool alors je vais le partager avec vous. Il s’agit d’un <strong>IDE totalement open source dédié aux bases de données</strong>. Cet outil libre simplifie les interactions que nous avons avec nos bases de données, ce qui rend leur administration et la gestion des données plus intuitives et surtout beaucoup plus facile. Vous allez voir !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1685582698\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Tout d’abord, <a href=\"https://webdb.app/\" target=\"_blank\" rel=\"noopener\"><strong>WebDB</strong></a> simplifie la découverte de serveurs et la connexion à ces derniers, grâce à un système de scan intelligent. Il détecte les ports utilisés pour chaque base de données et permet d’ajouter des hôtes spécifiques à analyser. Cela élimine la corvée de récupérer des mots de passe, car WebDB teste automatiquement des identifiants populaires. Pensez quand même à les changer à un moment pour des questions de sécurité 🙂</p>\n\n\n\n<p>En explorant plus profondément WebDB, on découvre que l’exploration de données est beaucoup plus facile et agréable que dans n’importe quel PhpMyAdmin ou autre. En seulement trois clics, on peut comme ça parcourir, mettre à jour ou supprimer des données. Le filtrage des données SQL et NoSQL se fait directement depuis l’explorateur, avec un design optimisé pour les clés étrangères et les ObjectID relationnels. Et ce n’est pas tout : WebDB permet de mettre à jours vos données par lots en utilisant des fichiers JSON. Pratiquement quand vous avez de la quantité à mettre à jour.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"559\" src=\"https://korben.info/app/uploads/2023/12/explore-1024x559.webp\" alt=\"\" class=\"wp-image-155799\" srcset=\"https://korben.info/app/uploads/2023/12/explore-1024x559.webp 1024w, https://korben.info/app/uploads/2023/12/explore-300x164.webp 300w, https://korben.info/app/uploads/2023/12/explore-768x419.webp 768w, https://korben.info/app/uploads/2023/12/explore-1536x838.webp 1536w, https://korben.info/app/uploads/2023/12/explore.webp 1686w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Le cœur de l’IDE WebDB réside dans son éditeur de requêtes. Avec de l’autocomplétion pour SQL et les structures spécifiques au serveur, rédiger des requêtes se fait en un clin d’œil. Les requêtes CRUD (create, read, update, and delete) pré-construites sont sauvegardées automatiquement et peuvent être marquées comme favorites.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"623\" src=\"https://korben.info/app/uploads/2023/12/sql-autocomplete-1024x623.webp\" alt=\"\" class=\"wp-image-155800\" srcset=\"https://korben.info/app/uploads/2023/12/sql-autocomplete-1024x623.webp 1024w, https://korben.info/app/uploads/2023/12/sql-autocomplete-300x182.webp 300w, https://korben.info/app/uploads/2023/12/sql-autocomplete-768x467.webp 768w, https://korben.info/app/uploads/2023/12/sql-autocomplete.webp 1240w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>La modification de colonnes SQL ou de champs NoSQL est également plus intuitive grâce à WebDB. Le logiciel propose tous les types possibles en fonction de la base de données et facilite la modification des colonnes avec des fonctions de casting intelligentes, applicables tant aux bases de données SQL qu’à NoSQL. Cette fonctionnalité permet une grande flexibilité et s’adapte à divers contextes linguistiques.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"943\" src=\"https://korben.info/app/uploads/2023/12/column-add-edit-1024x943.webp\" alt=\"\" class=\"wp-image-155801\" srcset=\"https://korben.info/app/uploads/2023/12/column-add-edit-1024x943.webp 1024w, https://korben.info/app/uploads/2023/12/column-add-edit-300x276.webp 300w, https://korben.info/app/uploads/2023/12/column-add-edit-768x707.webp 768w, https://korben.info/app/uploads/2023/12/column-add-edit.webp 1190w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1765731240\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Voilà… Sinon, WebDB gère également des éléments complexes comme les procédures SQL, les fonctions, et les types de données spécifiques. Il prend en charge les validateurs MongoDB et les contraintes SQL, offrant une compréhension complète de la base de données.</p>\n\n\n\n<p>La gestion des relations SQL dans WebDB est également totalement transparente grâce à une vue intuitive. L’outil déduit les relations pour aider à générer des données étrangères et à comprendre la structure de la base de données avec une facilité déconcertante. En plus, le versioning de base de données est une autre caractéristique clé de WebDB. Suivant les modifications et intégrant Git, il permet de revenir facilement à n’importe quelle version antérieure.</p>\n\n\n\n<p>L’intégration de ChatGPT dans WebDB apporte également un peu de « cerveau » à l’outil. ChatGPT offre des réponses précises en fonction de la structure de la base de données. Cette fusion entre intelligence artificielle et gestion de données ouvre de nouvelles perspectives pour les utilisateurs, surtout pour les débutants.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"884\" src=\"https://korben.info/app/uploads/2023/12/ai-dialog-1024x884.webp\" alt=\"\" class=\"wp-image-155802\" srcset=\"https://korben.info/app/uploads/2023/12/ai-dialog-1024x884.webp 1024w, https://korben.info/app/uploads/2023/12/ai-dialog-300x259.webp 300w, https://korben.info/app/uploads/2023/12/ai-dialog-768x663.webp 768w, https://korben.info/app/uploads/2023/12/ai-dialog.webp 1394w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Le module ERD de WebDB permet également de visualiser la structure et les relations de la base de données de manière moderne et intuitive. L’exportation de ces diagrammes au format PNG ou SVG se fait en un clic, ce qui vous permettra d’illustrer vos préz ou sites web / documentation super facilement.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"546\" src=\"https://korben.info/app/uploads/2023/12/erd-export-1024x546.webp\" alt=\"\" class=\"wp-image-155803\" srcset=\"https://korben.info/app/uploads/2023/12/erd-export-1024x546.webp 1024w, https://korben.info/app/uploads/2023/12/erd-export-300x160.webp 300w, https://korben.info/app/uploads/2023/12/erd-export-768x409.webp 768w, https://korben.info/app/uploads/2023/12/erd-export.webp 1430w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Enfin, l’importation et l’exportation de données avec WebDB sont simplifiées, que ce soit au format natif ou JSON, garantissant une compatibilité et des performances optimales. </p>\n\n\n\n<p>Vous l’aurez compris, Alexandre a bien bossé et WebDB se présente vraiment comme une solution complète et avant-gardiste pour la gestion des bases de données, accessible et efficace pour tous, que vous soyez total noob ou super expert en base de données.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-170344774\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p><a href=\"https://webdb.app/\" target=\"_blank\" rel=\"noopener\">Je vous invite à tester ça</a>.

Il offre des options pour sauvegarder les dumps, créer des vidages multiples, surveiller l'utilisation du processeur et de la mémoire, avec des seuils personnalisables.

Pour rappel, ProcDump est un outil de surveillance de processus et de débogage conçu pour permettre aux administrateurs système et aux développeurs de capturer des images de processus (des dumps) lorsqu’un processus atteint un certain critère, comme une utilisation élevée du CPU, une fuite de mémoire, ou une exception non gérée. Cela peut être utile pour identifier la cause profonde des pannes.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-324283312\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Et bien bonne nouvelle pour les Linuxiens, puisque Sysinternals a également sorti <a href=\"https://github.com/Sysinternals/ProcDump-for-Linux\" target=\"_blank\" rel=\"noopener\"><strong>ProcDump pour Linux</strong></a>. Ca fait tout pareil que son grand frère sous Windows et c’est compatible avec des distraits comme CentOS, Ubuntu ou encore Fedora.</p>\n\n\n\n<p><strong>Utilisation de base</strong></p>\n\n\n\n<p>Alors, c’est simple comme bonjour. Vous voulez garder un œil sur un processus particulier ? Rien de plus facile avec ProcDump. Tapez cette commande magique :</p>\n\n\n\n<p><code>sudo procdump [PID du processus]</code></p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1235404315\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Par exemple, pour espionner ce qui se passe dans le processus avec le PID 1234, lancez :</p>\n\n\n\n<p><code>sudo procdump 1234</code></p>\n\n\n\n<p>Et pouf ! Vous avez un joli vidage de mémoire à analyser. Mais attendez, il y a plus ! Vous voulez sauvegarder votre trésor ? Indiquez simplement un nom de fichier ou un répertoire :</p>\n\n\n\n<p><code>sudo procdump 1234 mondump.dmp</code></p>\n\n\n\n<p><strong>Création de plusieurs vidages</strong></p>\n\n\n\n<p>On passe à la vitesse supérieure ! Avec l’option <code>-n</code>, vous pouvez créer une série de vidages. Imaginez, vous pourriez avoir non pas un, mais TROIS vidages, en tapant :</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1911076332\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p><code>sudo procdump -n 3 1234</code></p>\n\n\n\n<p>Et si vous êtes du genre impatient, réglez l’intervalle entre chaque vidage avec <code>-s</code> :</p>\n\n\n\n<p><code>sudo procdump -n 3 -s 5 1234</code></p>\n\n\n\n<p>Trois vidages, toutes les 5 secondes. C’est pas génial, ça ?</p>\n\n\n\n<p><strong>Surveillance de l’utilisation du processeur</strong></p>\n\n\n\n<p>Et pour les mordus de performances, ProcDump peut aussi surveiller l’utilisation du processeur. Vous voulez un rapport dès que ça dépasse 65 % ? Facile :</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1557839000\" data-NKSYD1CP-trackid=\"124509\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_4' style='display:none;' class=\"Content_4\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos4' style='display:none;' class=\"Mobile_Pos4\"></div></div><p><code>sudo procdump -c 65 1234</code></p>\n\n\n\n<p>Ou pourquoi pas définir une plage ?

Vous serez alerté dès que le processus dépassera les 100 Mo :</p>\n\n\n\n<p><code>sudo procdump -m 100 1234</code></p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-584781808\" data-NKSYD1CP-trackid=\"124510\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_5' style='display:none;' class=\"Content_5\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos5' style='display:none;' class=\"Mobile_Pos5\"></div></div><p>Et pour les plus gourmands, spécifiez plusieurs seuils :</p>\n\n\n\n<p><code>sudo procdump -m 100,200,300 1234</code></p>\n\n\n\n<p>Allez, je ne vais pas vous faire l’article sur toutes les possibilités de cet outil de compét’, mais si vous êtes un Linuxien dans l’âme, c’est du caviar !</p>\n\n\n\n<p>Pour installer ProcDump sous Linux, je vous renvoie <a href=\"https://github.com/Sysinternals/ProcDump-for-Linux/blob/master/INSTALL.md\" target=\"_blank\" rel=\"noopener\">à la documentation ici</a>. <a href=\"https://github.com/Sysinternals/ProcDump-for-Linux\" target=\"_blank\" rel=\"noopener\">Les binaires et le reste des explications est ici</a>.</p>\n",

Bien qu’encore en développement, cet outil, est déjà suffisamment cool pour vous donner envie de l’utiliser afin de suivre vos tâches, vos sprints et autres feuilles de route.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"558\" src=\"https://korben.info/app/uploads/2023/12/hero-1024x558.webp\" alt=\"\" class=\"wp-image-155717\" srcset=\"https://korben.info/app/uploads/2023/12/hero-1024x558.webp 1024w, https://korben.info/app/uploads/2023/12/hero-300x164.webp 300w, https://korben.info/app/uploads/2023/12/hero-768x419.webp 768w, https://korben.info/app/uploads/2023/12/hero-1536x837.webp 1536w, https://korben.info/app/uploads/2023/12/hero-2048x1116.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>L’interface est plutôt agréable et vous permettra d’afficher les projets, d’y ajouter des pièces jointes, de créer des workflows maison, mais également d’importer toutes les tâches directement depuis d’autres outils comme Github ou Jira. Et bien sûr recevoir des notifs dans Slack, Discord et vos propres outils puisqu’il y a même une API.</p>\n\n\n\n<p>Vous pouvez également utiliser des <strong>cycles</strong> pour planifier des sprints, diviser les projets en <strong>modules</strong> et créer des <strong>filtres personnalisés</strong> pour trier les informations comme bon vous semble. Plane offre également la possibilité de faire de la documentation directement au fur et à mesure du développement de votre projet et tout s’intègre parfaitement à Github pour conserver à la fois votre code et vos issues synchronisées avec Plane.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-381790180\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Vous verrez, Plane est assez plaisant à prendre en main puisqu’il y a même Command K, un genre d’interface rapide à Spotlight pour chercher des tâches, créer de nouvelles actions….etc. sans oublier un petit bloc-notes propulsé à base de ChatGPT pour les grosses feignasses qui n’aiment pas écrire.</p>\n\n\n\n<p>Si ça vous branche, il n’y a plus qu’à découvrir <strong><a href=\"https://github.com/makeplane/plane\" target=\"_blank\" rel=\"noopener\">Plane</a></strong> et kiffer la vie de projets !

Pour le lancer, il suffit simplement de lui donner l’url du fichier à récupérer : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>aim https://domain.com/fichier.zip</code></pre>\n\n\n\n<p>Et pour uploader vers un endpoint c’est : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>aim fichier.zip https://domain.com/destination</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"956\" height=\"356\" src=\"https://korben.info/app/uploads/2023/12/aim.gif\" alt=\"\" class=\"wp-image-155699\"/></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-585294813\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Aim prend en charge plusieurs formats de sortie et vous permet de configurer des indicateurs personnalisés pour les barres de progression. Vous pouvez partager facilement des fichiers entre différentes machines et les télécharger à l’aide d’un simple navigateur.</p>\n\n\n\n<p>Vous pouvez par exemple partager un répertoire courant comme ceci :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>aim .</code></pre>\n\n\n\n<p>Et à partir d’une seconde machine, accéder à ce partage :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>aim http://ADRESSEIP:8080</code></pre>\n\n\n\n<p>Ou directement à un fichier précis : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>aim http://ADRESSEIP:8080/fichier.zip</code></pre>\n\n\n\n<p>L’une des particularités d’Aim est sa capacité à utiliser différentes méthodes d’authentification, telles que les <strong>URL basiques</strong>, les <strong>fichiers .netrc</strong>, les <strong>clés SSH</strong> et les <strong>dossiers AWS</strong>. Cela rend l’accès aux fichiers plus sécurisé et fiable, en évitant les problèmes d’authentification courants.</p>\n\n\n\n<p>Aim propose également un mode interactif avec l’option -i pour naviguer dans les fichiers dispo au bout d’une URL.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"800\" height=\"408\" src=\"https://korben.info/app/uploads/2023/12/aim_interactive.gif\" alt=\"\" class=\"wp-image-155701\"/></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-750023330\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Voilà pour la petite présentation d’Aim.

Vous avez déjà pris vos bonnes résolutions ? Parce que si ce n’est pas le cas, j’en ai une pour vous, et qui sera (peut-être) moins fatigante que le classique « se remettre au sport ». Ou mieux, prenez les 2 … oui je sais, je mets beaucoup de confiance en vous, mais j’ai décidé de commencer 2024 en voyant votre bon côté.</p>\n\n\n\n<p>Et cette résolution, c’est de vous décider à mettre toutes les chances de votre côté si vous cherchez un boulot dans le fabuleux monde du Devops ou que vous souhaitez évoluer dans votre position (demander une augmentation, etc.). En effet, les formations Kubernetes proposées par Ambient IT sont parmi les plus reconnues. Ça va booster votre niveau d’employabilité pour les recruteurs, ou vous permettre de mieux négocier votre salaire … ce n’est jamais inutile ! En plus, vous avez le choix du format entre présentiel et classe virtuelle, vous n’aurez même pas l’excuse du froid ! Autant rentabiliser votre temps à la maison cet hiver 😉</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"1440\" src=\"https://kbn.im/kbambient\" alt=\"\"/></figure></div>\n\n\n<p>Ce ne sont pas moins de <strong>5 certifications officielles issues de la Fondation Linux</strong> qui sont disponibles : KCNA, KCSA, CKAD, CKA et CKS. Je vous présente ça tout de suite :</p>\n\n\n\n<p>La formation <a href=\"https://www.ambient-it.net/formation/kcna/\" target=\"_blank\" rel=\"noopener\">KCNA</a> (pour Kubernetes and Cloud Native Associate), c’est celle qui vous permettra de maitriser toutes les bases fondamentales de la techno, mais aussi l’écosystème du cloud natif. Vous allez apprendre les architectures, les conteneurs et leurs organisations, les APIs, l’observabilité et l’optimisation des applis cloud native, etc. Si vous commencez votre parcours, c’est par là que vous allez démarrer, car il n’y a besoin d’aucun prérequis. En plus elle est assez rapide à passer (1 journée). </p>\n\n\n\n<p>La <a href=\"https://www.ambient-it.net/formation/certification-kcsa/\" target=\"_blank\" rel=\"noopener\">Kubernetes and Cloud Security Associate (KCSA)</a> de son côté est plus costaude (2 journées) et vous demandera de bien maitriser les bases. Sur 2 jours vous en apprendrez beaucoup plus sur la sécurité de votre environnement Kubernetes et du cloud natif : sécurité des pods, des conteneurs, des clusters et de l’infrastructure, modèles d’attaque (attaque réseau, codes malveillants …), etc. Vous apprendrez aussi à utiliser des choses comme l’outil en ligne de commande KubeCTL, Kubelet ou le mécanisme de sécurité RBAC.</p>\n\n\n\n<p>Passons à la certification <a href=\"https://www.ambient-it.net/formation/ckad/\" target=\"_blank\" rel=\"noopener\">CKAD</a> (sur 2 jours aussi) qui vous permet de devenir développeur d’application Kubernetes certifié. Comme son nom l’indique, elle vous donnera la possibilité de concevoir, configurer et lancer vos applis cloud natives. Mais aussi de les faire évoluer dans le temps. Ce sera donc l’occasion d’approfondir votre connaissance des pods, des services et mise en réseau ou encore du suivi (débug, observabilité, consommation de ressources …).</p>\n\n\n\n<p>Ensuite nous avons la CKA qui vous amènera à devenir <a href=\"https://www.ambient-it.net/formation/cka/\" target=\"_blank\" rel=\"noopener\">administrateur Kubernetes certifié</a>. Du stockage, au dépannage, en passant par la planification de pods et les charges de travail, vous serez à même de tout gérer. Vous apprendrez aussi à mettre en place et à gérer un cluster avec KubeADM et pas mal d’autres choses.</p>\n\n\n\n<p>Assez courte (1 jour), mais plutôt dense, la formation <a href=\"https://www.ambient-it.net/formation/cks/\" target=\"_blank\" rel=\"noopener\">CKS</a> (Certified Kubernetes Security Specialist) est, elle aussi, axée sécurité. De la mise en place à la protection d’un cluster, à la sécurisation du système, de la supply chain et des micro-services, en passant par la surveillance et la détection des attaques… vous deviendrez le spécialiste ultime de la sécu. Attention le niveau est relevé, il vous faut déjà posséder la certif CKA pour suivre cette certification et la <a href=\"https://korben.info/kubernetes-ambien-it.html\">formation Kubernetes avancée</a> est un plus.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"650\" height=\"228\" src=\"https://korben.info/app/uploads/2023/09/cartifications-kubernetes.jpg\" alt=\"\" class=\"wp-image-154038\" srcset=\"https://korben.info/app/uploads/2023/09/cartifications-kubernetes.jpg 650w, https://korben.info/app/uploads/2023/09/cartifications-kubernetes-300x105.jpg 300w\" sizes=\"(max-width: 650px) 100vw, 650px\" /></figure></div>\n\n\n<p>Ces formations durent chacune 1 ou 2 journées, donc c’est assez rapide et vous pouvez les cumuler au fil des semaines/mois. Elles sont proposées à des prix assez variés (de 995€ à 2190€ HT), prix qui comprend l’examen de passage de la formation (valeur 250€ à 395€). Et comme toujours, le bon plan c’est que vous pouvez faire valoir votre crédit CPF (compte personnel de formation) et d’autres aides. Petit point à prendre en compte tout de même, si les formations sont en français, les examens se font, eux, en anglais.</p>\n\n\n\n<p>Pourquoi passer par Ambient IT pour ces certifications ? Déjà parce qu’ils sont partenaires officiels de la Linux Foundation ET Kubernetes Training Partner. Ensuite parce que les formateurs sont d’un très bon niveau, que vous pouvez suivre tout cela à distance et vous recevrez même des conseils pour être paré à vos examens. De quoi vous mettre dans les meilleures conditions possibles !</p>\n\n\n\n<h2 class=\"wp-block-heading\">Promo spéciale Korben</h2>\n\n\n\n<p>Si vous me lisez régulièrement, vous savez que j’essaie toujours de vous dénicher de bons plans.

Concrètement, cela signifie que si quelque chose bouge devant votre caméra – que ce soit votre chat ou un voleur – Frigate le sait, le reconnait, et vous le savez aussi, instantanément.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"666\" src=\"https://korben.info/app/uploads/2023/12/media_browser-1024x666.webp\" alt=\"\" class=\"wp-image-155674\" style=\"width:808px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/12/media_browser-1024x666.webp 1024w, https://korben.info/app/uploads/2023/12/media_browser-300x195.webp 300w, https://korben.info/app/uploads/2023/12/media_browser-768x499.webp 768w, https://korben.info/app/uploads/2023/12/media_browser.webp 1257w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>L’intégration avec Home Assistant est tellement fluide qu’elle vous donnera l’impression que Frigate fait partie intégrante de votre install. Vous pouvez ainsi contrôler et consulter votre système de sécurité sans jamais quitter votre interface Home Assistant familière. Bien sûr, si vous êtes sur Raspberry Pi, soyez rassurés puisque Frigate est conçu pour être économe. Il sait quand être « attentif » mais aussi quand rester en veille, assurant ainsi une surveillance efficace sans gaspiller de ressources. Et si vous voulez passer à la vitesse supérieure, ajoutez un accélérateur <a href=\"https://amzn.to/46ScO0T\" target=\"_blank\" rel=\"noopener\"><strong>Google Coral</strong></a> et vous verrez Frigate traiter les images encore plus vite !!</p>\n\n\n\n<p>Ainsi, Frigate vous permettra de réduire les fausses alertes. Il est capable de faire la distinction entre les mouvements pertinents (personnes, voitures) et non pertinents (ombres, vent). L’utilisation de l’IA permet comme ça de filtrer uniquement les détections importantes et éviter de manquer les trucs importants.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1596527194\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>La clé de la performance de Frigate réside dans sa capacité à faire plusieurs choses à la fois. Il divise les tâches tout en s’assurant que la détection d’objets ne ralentisse jamais le flux de vos vidéos. De plus, l’enregistrement est aussi intelligent que la détection puisque Frigate ne garde que ce qui compte, en se basant sur les objets qu’il identifie. Vous pourrez donc dire enfin adieu aux heures de vidéo enregistrées inutiles.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"513\" src=\"https://korben.info/app/uploads/2023/12/events-ui-1024x513.webp\" alt=\"\" class=\"wp-image-155672\" srcset=\"https://korben.info/app/uploads/2023/12/events-ui-1024x513.webp 1024w, https://korben.info/app/uploads/2023/12/events-ui-300x150.webp 300w, https://korben.info/app/uploads/2023/12/events-ui-768x385.webp 768w, https://korben.info/app/uploads/2023/12/events-ui.webp 1214w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Frigate offre ainsi du suivi en temps réel des objets et des notifications précises lorsqu’une personne s’approche de votre porte ou qu’une voiture entre dans votre allée.</p>\n\n\n\n<p>Et pour ceux qui veulent garder un œil sur leur maison sans compliquer les choses, Frigate offre une retransmission du flux vidéo via RTSP pour limiter le nombre de connexions directes à toutes vos caméras IP. De plus, la faible latence et la visualisation en direct signifient que vous pouvez voir ce qui se passe chez vous grâce au WebRTC & MSE, où que vous soyez, et tout cela en temps réel.</p>\n\n\n\n<p>Frigate n’est pas seulement un outil qui fonctionne de manière isolée puisqu’il est également capable de communiquer via MQTT, ce qui signifie qu’il peut s’intégrer facilement dans un écosystème de maison intelligente plus large.</p>\n\n\n\n<p>En bref, Frigate ne se contente pas de regarder ce qui se passe chez vous. Il comprend ce qui se passe chez vous et ça, ça vous permettra de faire toute la différence au niveau des scénarios de votre installation domotique.</p>\n\n\n\n<p><a href=\"https://github.com/blakeblackshear/frigate\" target=\"_blank\" rel=\"noopener\">À découvrir ici.</a></p>\n",

Parce que je vous connais, vous avez encore procrastiné cet achat de protection numérique malgré les dernières offres à prix cassé de ces dernières semaines. Et parce que le budget fromage à raclette passait avant tout.</p>\n\n\n\n<p>Mais vous avez changé ! Vous avez décidé de démarrer 2024 en prenant vos responsabilités et en protégeant toute votre famille. De l’ordinateur familial, à la tablette de votre conjoint(e), en passant par la console du gamin et aux smartphones de tout le monde. Tous les appareils du domicile pourront être protégés via un seul abonnement Surfshark VPN.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"262\" src=\"https://kbn.im/srfshrkjanvier2024\" alt=\"\"/></figure></div>\n\n\n<p>Je pourrai m’arrêter là, car de l’illimité en simultané il n’y a quasi qu’eux pour le proposer. Mais c’est aussi l’un des VPN les plus actif et novateur, avec pas mal de nouveautés proposées rien qu’en 2023 ! L’occasion de fêter leurs 5 ans d’existence.</p>\n\n\n\n<p>On commence par le début : la connexion. Puisqu’il est possible de connecter autant de machines que vous voulez à votre compte, entrer un mot de passe complexe chaque fois n’était pas le plus rapide (bien choisir ses mots de passe). Dorénavant il est possible de le faire via le scan d’un simple QR Code ou via votre compte Google/Apple. À vous de choisir entre sécurité et facilité d’utilisation.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2004681049\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>L’ajout du <strong>MultiHop dynamique</strong>. Apparue début 2023, cette fonctionnalité permet de vous connecter à 2 serveurs en même temps … de manière dynamique. Ce qui rend encore plus difficile le suivit de votre activité en ligne. Le multihop n’est pas nouveau en soi (l’option existait déjà par le passé, mais avec 2 serveurs prédéterminés), c’est plutôt la personnalisation qui l’est. Vous pouvez maintenant choisir vos serveurs de connexions Surfshark en fonction de <a href=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" data-type=\"link\" data-id=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\">ceux qui vous conviennent le mieux</a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"280\" src=\"https://korben.info/app/uploads/2024/01/surfshark-vpn-multihop.jpg\" alt=\"Surfshark VPN MultiHop dynamique\" class=\"wp-image-155967\" srcset=\"https://korben.info/app/uploads/2024/01/surfshark-vpn-multihop.jpg 750w, https://korben.info/app/uploads/2024/01/surfshark-vpn-multihop-300x112.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></figure></div>\n\n\n<p><strong>L’automatisation a aussi fait son apparition</strong> (surtout sur iOS pour l’instant). Vous pouvez dorénavant activer/désactiver automatiquement votre VPN selon des actions spécifiques et/ou via commandes vocales. Démarrage à une certaine heure, mise en route en fonction du site visité ou du réseau wifi détecté, etc. Ce n’est pas une révolution en soi, mais c’est plutôt pratique.</p>\n\n\n\n<p><strong>Toujours plus rapide</strong> ! Cela fait maintenant plusieurs mois que le VPN améliore son parc de serveurs à travers le monde. Ces derniers passent peu à peu d’une vitesse de 1Gb/s à 10Gb/s, un petit x10 qui fera plaisir à tout le monde. Et qui prépare l’arrivée massive de la 5G dans les prochains mois.</p>\n\n\n\n<p><strong>La protection de votre webcam</strong>. Ajoutée courant de l’année, cette option vous permet de gérer les applications dont vous voulez bloquer ou autoriser l’accès à votre caméra. Et si une application veut y accéder sans votre consentement, une notification vous préviendra. Certains vont faire des économies de <s>duct tape</s> papier collant 😉</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"480\" height=\"270\" src=\"https://media.giphy.com/media/B6cpha9FVo3Li36Tzk/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Du côté de la fonctionnalité <strong>Surfshark Alert</strong>, ils vont un peu plus loin. Alors que le but initial était de simplement vous alerter si vos données personnelles avaient fuité quelque part, maintenant vous recevez aussi des indications de quoi en faire. Vous saurez donc quel site à leaké vos infos, à quelle date, quelles sont les données concernées et quelles actions effectuer le plus rapidement possible.</p>\n\n\n\n<p>Je passe rapidement sur les différentes améliorations visuelles et d’UX, car elles parsèment la vie de quasi tous les logiciels existants. Rien de très spécial même si cette fois c’est notamment le tableau de bord dans son ensemble qui a été retravaillé. Nous avons aussi eu droit à une refonte de la fonctionnalité Cleanweb, plus de lisibilité et d’unicité entre les applications et la version desktop, etc.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1978813172\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Quant à la <a href=\"https://korben.info/surfshark-one-se-dote-de-loption-creation-didentite-alternative-promo-rentree-2023.html\" data-type=\"link\" data-id=\"https://korben.info/surfshark-one-se-dote-de-loption-creation-didentite-alternative-promo-rentree-2023.html\">création d’identités alternatives</a> ou l’arrivée de <a href=\"https://korben.info/lip-fixe-debarque-chez-surfshark.html\" data-type=\"link\" data-id=\"https://korben.info/lip-fixe-debarque-chez-surfshark.html\">l’IP fixe</a>, j’en ai déjà parlé en détail, je ne reviens donc pas dessus. Et pour finir l’année, Surfshark a lancé un début de <a href=\"https://learning.surfshark.com/\" data-type=\"link\" data-id=\"https://learning.surfshark.com/\" target=\"_blank\" rel=\"noreferrer noopener\">centre de formation</a> avec une première série basée la compréhension des différentes menaces (plus d’une centaine), les ressorts psychologiques utilisés par les hackers, etc. Des vidéos, quiz et ressources à télécharger pour 30$ (ou 20$ si vous utilisez le VPN).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"305\" src=\"https://korben.info/app/uploads/2024/01/surfshark-formations.jpg\" alt=\"Formations Surfshark\" class=\"wp-image-155966\" srcset=\"https://korben.info/app/uploads/2024/01/surfshark-formations.jpg 700w, https://korben.info/app/uploads/2024/01/surfshark-formations-300x131.jpg 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" /></figure></div>\n\n\n<p>L’outil a également continué à passer des audits de sécu avec succès. Comme l’audit indépendant Mobile App Security Assessment (MASA), validé il y a quelques jours.</p>\n\n\n\n<p>Bref il y a encore eu pas mal de choses à se mettre sous la dent en 2023, et avec tous ces ajouts le prix n’a pas changé ! À savoir que vous pouvez bénéficier du VPN pendant 28 mois pour moins de 67€ TTC ! (moins de 2.4€/mois). N’attendez plus et démarrez 2024 en sécurité 😉</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" data-type=\"link\" data-id=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Essayer Surfshark VPN</a></h2>\n",

Cela représente un avantage majeur pour les utilisateurs qui ne sont pas familiers avec les aspects techniques de la gestion de systèmes d’exploitation.</p>\n\n\n\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"679\" height=\"331\" src=\"https://korben.info/app/uploads/2023/12/247650724-304fdbd8-ffd7-4127-96d2-23adf672724c.webp\" alt=\"\" class=\"wp-image-155620\" srcset=\"https://korben.info/app/uploads/2023/12/247650724-304fdbd8-ffd7-4127-96d2-23adf672724c.webp 679w, https://korben.info/app/uploads/2023/12/247650724-304fdbd8-ffd7-4127-96d2-23adf672724c-300x146.webp 300w\" sizes=\"(max-width: 679px) 100vw, 679px\" /></figure>\n\n\n\n<p class=\"\">WSA System Control se distingue également par sa compatibilité et sa facilité d’installation. Il est disponible pour les versions Windows 10 et 11, assurant ainsi une large couverture des systèmes d’exploitation les plus utilisés. Pour l’installer, plusieurs options s’offrent à vous : le <a href=\"https://apps.microsoft.com/store/detail/9PFCTFQ8V8C3?launch=true&cid=ghreadme&mode=mini\" target=\"_blank\" rel=\"noopener\">Store Microsoft</a>, <a href=\"https://github.com/infinitepower18/WSA-SystemControl/releases/latest\" target=\"_blank\" rel=\"noopener\">Github</a> ou directement via <a href=\"https://winstall.app/apps/infinitepower18.WSASystemControl\" target=\"_blank\" rel=\"noopener\">Winget</a>, une méthode pratique pour les utilisateurs avertis. Le logiciel est également compatible avec les versions de WSA utilisant Android 13 ou supérieur, garantissant ainsi une compatibilité avec les versions les plus récentes et performantes de WSA.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-952236016\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p class=\"\">Un autre point fort de WSA System Control est sa présence discrète mais efficace dans la barre des tâches de Windows. Grâce à une icône dédiée, vous pouvez obtenir des informations en temps réel sur l’état de WSA. Cela signifie que vous pouvez rapidement voir si WSA est actif, inactif, ou en cours d’exécution, sans avoir à ouvrir le logiciel lui-même. Cette fonctionnalité apporte une commodité et une efficacité accrues, en particulier pour ceux qui utilisent fréquemment des applications Android sur leur PC Windows.</p>\n\n\n\n<p class=\"\">Pour conclure, WSA System Control est un outil pratique et facile à utiliser, offrant une gestion améliorée et une interface utilisateur intuitive pour tous ceux qui utilisent le Windows Subsystem for Android. Que vous soyez un utilisateur occasionnel d’applications Android sur Windows ou que vous ayez besoin de ces applications pour des raisons professionnelles, WSA System Control est une solution incontournable pour optimiser votre expérience.</p>\n",

Cette technique est souvent utilisée pour masquer aux yeux des scanners de ports, des services comme SSH. les services tels que SSH (Secure Shell) des scanners de port automatiques et des attaquants potentiels.</p>\n\n\n\n<p>Cette méthode ajoute une couche de sécurité supplémentaire, car les ports nécessaires pour accéder à votre serveur, ne sont pas constamment ouverts et donc visibles.</p>\n\n\n\n<p>Si vous voulez mettre ça en place, il y a différentes méthodes, mais l’une des plus faciles, c’est d’utiliser Knockr, un script écrit en Go qui s’installe comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>go install github.com/solutionroute/knockr@v0.2.0</code></pre>\n\n\n\n<p>Ou comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/solutionroute/knockr.git\ncd knockr\ngo install</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2110369276\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Et qui va vous permettre de spécifier les ports à surveiller ainsi que la durée d’attente entre chaque frappe, le protocole réseau utilisé ou le temps d’attente avant l’émission d’une nouvelle séquence.</p>\n\n\n\n<p><strong>Frapper sur trois ports différents</strong></p>\n\n\n\n<p>Le comportement par défaut de l’outil <code class=\"\">knockr</code> est de frapper sur les ports spécifiés en utilisant le protocole TCP avec un délai de 100 millisecondes entre les frappes et un délai d’expiration de 1,5 seconde pour chaque frappe. Pour frapper sur trois ports, 1234, 8923 et 1233, vous utiliseriez la commande suivante, en remplaçant hostname par le nom réseau de votre machine :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>knockr hostname 1234,8923,1233</code></pre>\n\n\n\n<p>Cette commande enverra un paquet TCP SYN à chacun des ports spécifiés, en attendant une réponse avant d’envoyer le paquet suivant. Si une réponse n’est pas reçue dans les 1,5 secondes, la frappe est considérée comme infructueuse.</p>\n\n\n\n<p><strong>Frapper sur une chaîne de ports avec un protocole et un délai spécifiés</strong></p>\n\n\n\n<p>Pour spécifier un protocole et un délai différents entre les frappes, vous pouvez utiliser les options <code class=\"\">-n</code> et <code class=\"\">-d</code>, respectivement. Par exemple, pour frapper sur le port 22 (SSH) en utilisant le protocole UDP avec un délai de 200 millisecondes entre les frappes, vous utiliseriez la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>knockr hostname 22 -n udp -d 200ms</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1528586257\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p><strong>Frapper sur une chaîne de ports avec un protocole, un délai et un mode silencieux spécifiés</strong></p>\n\n\n\n<p>Pour supprimer tout sauf la sortie d’erreur, vous pouvez utiliser l’option <code class=\"\">-s</code>. Par exemple, pour frapper sur le port 22 (SSH) en utilisant le protocole TCP avec un délai de 200 millisecondes et supprimer toute sortie sauf la sortie d’erreur, vous utiliseriez la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>knockr hostname 22 -n tcp -d 200ms -s</code></pre>\n\n\n\n<p>Il est recommandé d’inclure le ou les ports que vous vous attendez à être déverrouillés en premier et en dernier dans la chaîne pour observer leur statut avant et après le processus de frappe. Par exemple, si vous avez l’intention de déverrouiller le port 22 (SSH) sur un hôte spécifique, vous pouvez utiliser la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>knockr hostname 22,1234,18923,1233,22</code></pre>\n\n\n\n<p>Cette commande frappera sur le port 22, attendra la réponse attendue, frappera ensuite sur les ports restants, puis vérifiera à nouveau le statut du port 22. Cela permet de garantir que les ports spécifiés sont bien déverrouillés après le processus de frappe.</p>\n\n\n\n<p>Vous l’aurez compris grâce aux exemples : </p>\n\n\n\n<ul>\n<li>L’option <code class=\"\">-d</code> spécifie le délai en millisecondes entre les frappes. La valeur par défaut est de 100 millisecondes.</li>\n\n\n\n<li>L’option <code class=\"\">-n</code> spécifie le protocole à utiliser pour les frappes. Les valeurs possibles sont <code class=\"\">tcp</code> et <code class=\"\">udp</code>. La valeur par défaut est <code class=\"\">tcp</code>.</li>\n\n\n\n<li>L’option <code class=\"\">-s</code> met l’outil en mode silencieux. Cela signifie que seules les sorties d’erreur seront affichées.</li>\n</ul>\n\n\n\n<p><a href=\"https://github.com/solutionroute/knockr\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a> et bonne chance dans vos aventures de port-knocking !</p>\n",

Homedale est également équipé d’une fonctionnalité de géolocalisation qui, lorsque disponible, peut vous aider à localiser physiquement les réseaux Wi-Fi sur une carte. Cela peut être particulièrement intéressant pour les professionnels effectuant des audits de réseau ou pour ceux qui cherchent simplement à optimiser la couverture Wi-Fi dans de grands espaces.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1207438939\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Bref, si ça vous dit d’essayer, <a href=\"https://www.the-sz.com/products/homedale/\" target=\"_blank\" rel=\"noopener\">Homedale c’est par ici</a>.</p>\n",

Et bien grâce à Grype qui n’est pas un virus, mais un incroyable scanner de vulnérabilités qui peut analyser les images de conteneurs Docker, OCI et <a href=\"https://github.com/sylabs/singularity\" target=\"_blank\" rel=\"noopener\">Singularity</a> et les systèmes de fichiers. </p>\n\n\n\n<p>Cet outil est ainsi capable de débusquer des vulns sur les systèmes d’exploitation containérisés tels que Alpine, Amazon Linux, BusyBox, CentOS, Debian, Ubuntu, mais également tout ce qui est vulnérabilités relatives à des langages de dev tels que Ruby, Java, JavaScript, Python, Dotnet, Golang, sans oublier PHP !</p>\n\n\n\n<p>Pour l’installer, vous pouvez récupérer <a href=\"https://github.com/anchore/grype\" target=\"_blank\" rel=\"noopener\">le binaire sur Github</a> ou lancer la commande Curl suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>curl -sSfL https://raw.githubusercontent.com/anchore/grype/main/install.sh | sh -s -- -b /usr/local/bin</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1125832829\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Si vous êtes sous Mac, en plus d’être un beau gosse, vous pouvez aussi l’installer avec Brew : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>brew tap anchore/grype\nbrew install grype</code></pre>\n\n\n\n<p>Ensuite, pour le lancer, rien de plus simple, vous appelez la commande, suivi du nom de l’image Docker telle qu’on la trouve sur le hub.docker.com par exemple. Voici un exemple de scan avec cette image de l’éditeur Balena :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>./grype <strong>balena/open-balena-vpn</strong></code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"675\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231205-l5b-1024x675.webp\" alt=\"\" class=\"wp-image-155568\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231205-l5b-1024x675.webp 1024w, https://korben.info/app/uploads/2023/12/SCR-20231205-l5b-300x198.webp 300w, https://korben.info/app/uploads/2023/12/SCR-20231205-l5b-768x507.webp 768w, https://korben.info/app/uploads/2023/12/SCR-20231205-l5b-1536x1013.webp 1536w, https://korben.info/app/uploads/2023/12/SCR-20231205-l5b.webp 1613w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Et pour ne voir que les vulnérabilité existantes pour lesquelles il existe un fix, vous pouvez également ajouter le paramètre suivant : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>./grype <strong>balena/open-balena-vpn</strong> --only-fixed</code></pre>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"561\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231205-l85-1024x561.webp\" alt=\"\" class=\"wp-image-155569\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231205-l85-1024x561.webp 1024w, https://korben.info/app/uploads/2023/12/SCR-20231205-l85-300x164.webp 300w, https://korben.info/app/uploads/2023/12/SCR-20231205-l85-768x421.webp 768w, https://korben.info/app/uploads/2023/12/SCR-20231205-l85-1536x842.webp 1536w, https://korben.info/app/uploads/2023/12/SCR-20231205-l85.webp 1613w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Par défaut Grype scanne uniquement les vulnbérabilités visibles du conteneur, mais si vous voulez faire un truc plus en profondeur et scanner toutes les couches de ce même conteneur, ajoutez le paramètre suivant :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>./grype <strong>balena/open-balena-vpn</strong> --scope all-layers</code></pre>\n\n\n\n<p>Au niveau des exports, vous pouvez sortir tout ça sous la forme d’un tableau dans le terminal, ou d’un rapport JSON ou XML pour ensuite l’interroger avec des outils comme <a href=\"https://korben.info/convertir-sortie-commande-format-json.html\">jq</a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1281\" height=\"1066\" src=\"https://korben.info/app/uploads/2023/12/90276236-9868f300-de31-11ea-8068-4268b6b68529.gif\" alt=\"\" class=\"wp-image-155571\"/></figure></div>\n\n\n<p>L’utilisation de Grype vous permet également un niveau élevé de personnalisation. Vous pouvez ainsi définir la portée de la recherche avec des expressions permettant d’inclure ou exclure certains fichiers ou répertoires. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-577160601\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Un autre atout majeur de Grype est sa capacité à intégrer des sources de données externes pour une meilleure correspondance des vulnérabilités. Ainsi, il peut analyser les données provenant de bases telles que Alpine Linux SecDB ou Debian Linux CVE Tracker pour vous fournir des informations encore plus précises sur les failles potentielles que votre image pourrait présenter.</p>\n\n\n\n<p>En parlant d’intégration, si vous travaillez avec GitHub et utilisez les Actions GitHub, Grype s’intègre parfaitement pour exécuter des analyses de vulnérabilités lors de vos workflows CI, assurant ainsi la sécurité de votre code et de vos conteneurs à chaque étape du processus.</p>\n\n\n\n<p>Bref, dans l’ensemble, Grype est un outil essentiel pour tous ceux qui souhaitent garantir la sécurité et l’intégrité de leurs images Docker et pas que. Que ce soit pour identifier les vulnérabilités ou tirer parti des fonctionnalités avancées telles que les sources externes et l’intégration des actions GitHub, Grype est un allié de taille dans la lutte continuelle contre les failles potentielles qui peuvent compromettre votre infrastructure.</p>\n\n\n\n<p><a href=\"https://github.com/anchore/grype\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Et bien comme c’est le cas pour de nombreux outils utilisant l’intelligence artificielle, les choses avancent vite. Parfois très très vite. Du coup, <strong>Filmora 13 est déjà là</strong>, avec son lot d’améliorations et de nouveautés (et il y en a un paquet).</p>\n\n\n\n<p>Filmora continue de faire ce pour quoi il existe : vous permettre de <strong>faire du montage vidéo très facilement</strong> via une interface simplifiée (dispo en français). Et pas uniquement pour de la vidéo simple, mais surtout ce qui touche aux différents formats sur les réseaux sociaux. Un short YouTube, un Tik Tok, une stories Instagram, un reel … il gère et adapte tout.</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://filmora.wondershare.fr/\" rel=\"noreferrer noopener\" target=\"_blank\"><strong>T</strong>ester gratuitement Filmora</a></h2>\n\n\n\n<p>Cette ouverture vers le social est vraiment son gros point fort, car cela permet d’optimiser non seulement votre temps, mais aussi votre process général. Il propose par exemple différents filtres et effets, différents outils et formats, est dispo sur plusieurs OS comme Windows, Linux, macOS et Android. Vous pouvez travailler seul ou en équipe et cela depuis un desktop, une tablette ou un smartphone au choix (ou depuis les 3, car vous aurez la synchronisation). Dans mon cas je l’utilise notamment pour couper les blancs et accélérer le rythme de mes créations.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"739\" src=\"https://kbn.im/filmora13\" alt=\"\"/></figure></div>\n\n\n<h2 class=\"wp-block-heading\">Filmora et l’IA</h2>\n\n\n\n<p>L’IA apporte un vrai intérêt puisqu’elle permet d’automatiser pas mal de tâches assez répétitives ou assez pénibles à faire à la main. Un vrai bonheur que d’obtenir différents formats de sorties aux résolutions des différentes plateformes que vous utilisez ou d’intégrer des animations, effets visuels & Co via de simples drag-and-drop. Surtout qu’il y a déjà base de modèles prêts à l’emploi si vous êtes en manque d’idées.</p>\n\n\n\n<p>Et <a href=\"https://filmora.wondershare.fr/\" data-type=\"link\" data-id=\"https://filmora.wondershare.fr/\" target=\"_blank\" rel=\"noreferrer noopener\">cette nouvelle version 13</a> se concentre avant tout sur une série de nouveaux produits et surtout sur les aspects IA voix et musique. Elle va proposer du découpage intelligent (qui vous permet de retirer tout élément dérangeant dans votre création en 2 clics), d’ajouter de la musique en rapport avec le mood de l’image (déjà 20 000 sons/pistes audio), créer des miniatures, utiliser vos meilleurs prompts et un tas d’autres. Vous disposez donc maintenant d’une sorte d’assistant virtuel qui va rendre tout le processus de création beaucoup plus digérable et interactif.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"512\" src=\"https://korben.info/app/uploads/2023/11/filmora-13-interface-audio.jpg\" alt=\"Interface audio Filmora 13\" class=\"wp-image-155387\" srcset=\"https://korben.info/app/uploads/2023/11/filmora-13-interface-audio.jpg 1000w, https://korben.info/app/uploads/2023/11/filmora-13-interface-audio-300x154.jpg 300w, https://korben.info/app/uploads/2023/11/filmora-13-interface-audio-768x393.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Une fois Filmora démarré, vous pouvez lancer une conversation avec l’IA Copilot intégrée afin que l’outil vous accompagne dans votre montage. C’est très pratique. Il suffit pour cela de faire un clic droit sur votre clip puis de sélectionner « Filmora Copilot »</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"458\" height=\"230\" src=\"https://korben.info/app/uploads/2023/11/SCR-20231127-ebg.webp\" alt=\"\" class=\"wp-image-155424\" style=\"width:458px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/11/SCR-20231127-ebg.webp 458w, https://korben.info/app/uploads/2023/11/SCR-20231127-ebg-300x151.webp 300w\" sizes=\"(max-width: 458px) 100vw, 458px\" /></figure></div>\n\n\n<p>Une fenêtre avec un Chatbot va alors s’ouvrir et vous pourrez lui demander de l’aide.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"652\" height=\"819\" src=\"https://korben.info/app/uploads/2023/11/SCR-20231127-ec9.png\" alt=\"\" class=\"wp-image-155425\" style=\"width:496px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/11/SCR-20231127-ec9.png 652w, https://korben.info/app/uploads/2023/11/SCR-20231127-ec9-239x300.png 239w\" sizes=\"(max-width: 652px) 100vw, 652px\" /></figure></div>\n\n\n<p>Ensuite, y’a plus qu’à faire comme il dit, et voilà, je peux ajouter de la musique en fond si j’en ai envie.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"622\" height=\"604\" src=\"https://korben.info/app/uploads/2023/11/SCR-20231127-ect.webp\" alt=\"\" class=\"wp-image-155426\" srcset=\"https://korben.info/app/uploads/2023/11/SCR-20231127-ect.webp 622w, https://korben.info/app/uploads/2023/11/SCR-20231127-ect-300x291.webp 300w\" sizes=\"(max-width: 622px) 100vw, 622px\" /></figure></div>\n\n\n<p>Envie de modifier la musique en background ou séparer des voix ? Une simple commande texte à votre assistant et le tour est joué. Modifier le discours lu par votre avatar virtuel à l’écran ? Faites simplement les modifs directement dans votre texte. Combiner plusieurs clips, étalonner les couleurs, synchroniser les vitesses vidéo/audio, placer des marqueurs, changer l’image d’arrière-plan ou ajouter votre logo, créer une police d’écriture personnalisée … les fonctionnalités sont déjà nombreuses (plus de détails dans mon article précédent) et d’autres sont ajoutées à un rythme régulier.</p>\n\n\n\n<p>Evidemment, si vous voulez en savoir plus sur les nouveautés ou apprendre à maitriser le logiciel comme un pro, le mieux c’est encore d’aller vous abonner à la chaine Youtube de Wondershare <a href=\"https://www.youtube.com/@FilmoraVideoEditorFrance\" target=\"_blank\" rel=\"noopener\">en cliquant ici</a>.</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Quoi d'neuf dans Filmora 13 !\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/y-v2XZSJH4A?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<h2 class=\"wp-block-heading\">Pour qui ?</h2>\n\n\n\n<p>À partir du moment où vous avez l’envie d’être présent sur plusieurs plateformes et de partager du contenu avec votre communauté (marketing, influenceurs, freelance …), vous trouverez un intérêt à Filmora. Il vous aidera à donner un côté pro à vos créations, à moindres frais et en économisant des heures de boulot !</p>\n\n\n\n<p>Dès la version 12, je vous annonçais que les futures avancées seraient folles. La version 13 fait déjà un grand pas vers l’avant alors qu’il n’y a que quelques mois entre les 2, imaginez le niveau du truc d’ici seulement 1 an ! Il pourrait vite devenir un incontournable pour de nombreux créatifs qui voudront être présents sur plusieurs sites.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"560\" src=\"https://korben.info/app/uploads/2023/05/Manu23_a_magician_doing_magic_on_a_computer_33dc9de6-2004-4a64-b548-ccbefaccd69e.webp\" alt=\"\" class=\"wp-image-152102\" srcset=\"https://korben.info/app/uploads/2023/05/Manu23_a_magician_doing_magic_on_a_computer_33dc9de6-2004-4a64-b548-ccbefaccd69e.webp 1000w, https://korben.info/app/uploads/2023/05/Manu23_a_magician_doing_magic_on_a_computer_33dc9de6-2004-4a64-b548-ccbefaccd69e-300x168.webp 300w, https://korben.info/app/uploads/2023/05/Manu23_a_magician_doing_magic_on_a_computer_33dc9de6-2004-4a64-b548-ccbefaccd69e-768x430.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Filmora va même jusqu’à proposer des vidéos formatives, de l’optimisation des revenus sur YouTube, de créer vos propres effets, etc. C’est super complet. Cerise sur le gâteau ? La version gratuite vous permet de tester l’outil avec 1 Go d’espace de stockage offert, de quoi se faire une idée assez précise de ce qu’il offre. Bref vous ne perdez rien à l’essayer ! En plus c’est le bon moment parce que s’il vous convient, la promo Black Friday vous permet de gagner presque la moitié du prix (-45 à -49% selon le type d’abonnement). L’achat a vie du logiciel vous coutera autour des 75€ (taxes comprises) et pour accéder à l’ensemble des effets, modèles et plugins supplémentaires, cela reviendra à 18,99€/mois.</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://filmora.wondershare.fr/\" data-type=\"link\" data-id=\"https://filmora.wondershare.fr/\" target=\"_blank\" rel=\"noreferrer noopener\">Tester Filmora avec cet essai gratuit</a></h2>\n",

Et c’est cool ! Mais dans d’autres pays, ou sur certains Hotspot Wifi, on doit parfois faire comme les accros au chocolat que je suis : surveiller sa consommation.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1233176000\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Pas évident sans l’outil approprié. C’est pourquoi aujourd’hui, je vous propose ce logiciel pour Mac nommé <em>Bandwidth+</em>.</p>\n\n\n\n<p>Ce petit utilitaire permet de suivre votre consommation de data, que vous soyez en Ethernet ou sur du wifi. Il se loge dans la barre de menu et ne nécessite aucune configuration complexe. Ça commence à comptabiliser dès que c’est lancé et vous avez ainsi en permanence une vue de ce que vous consommez en temps réel.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"341\" height=\"168\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231202-axt.webp\" alt=\"\" class=\"wp-image-155508\" style=\"width:475px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231202-axt.webp 341w, https://korben.info/app/uploads/2023/12/SCR-20231202-axt-300x148.webp 300w\" sizes=\"(max-width: 341px) 100vw, 341px\" /></figure></div>\n\n\n<p>Et ce que je peux vous dire c’est que ça part très vite la data… Vous seriez surpris. Je pars souvent à la chasse aux fichiers qui prennent de la place inutilement sur mon disque dur, mais jamais à la chasse à toutes ces applications qui transmettent des datas dans tous les sens.</p>\n\n\n\n<p>Bandwidth+ affiche ainsi le cumul de ce qui rentre et de ce qui sort, tel un bon dealer, et surtout, l’outil respecte votre vie privée puisqu’il <a href=\"http://bandwidthapp.s3.amazonaws.com/privacy.html\" target=\"_blank\" rel=\"noopener\">ne collecte et ne transmet aucune donnée utilisateur</a>. C’est un logiciel minimaliste et sain.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"592\" height=\"536\" src=\"https://korben.info/app/uploads/2023/12/SCR-20231202-b3r.webp\" alt=\"\" class=\"wp-image-155510\" srcset=\"https://korben.info/app/uploads/2023/12/SCR-20231202-b3r.webp 592w, https://korben.info/app/uploads/2023/12/SCR-20231202-b3r-300x272.webp 300w\" sizes=\"(max-width: 592px) 100vw, 592px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1880765247\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Bref, que vous soyez sur un Wifi « limité » ou que vous vouliez suivre l’utilisation de votre iPhone en mode partage de connexion, c’est un vrai bonheur pour éviter les mauvaises surprises avec votre forfait. Néanmoins, il faut noter que le trafic du réseau local n’est pas ignoré, et par conséquent les sauvegardes Time Machine ou autre sont comptabilisées. Mais le dev prévoit d’améliorer cela dans une version future.</p>\n\n\n\n<p>Ce qui serait cool également, c’est que le dev intègre un blocage automatique dès qu’un certain seuil est dépassé. Cela permettrait d’esquiver encore mieux les surcoûts. Affaire à suivre donc. </p>\n\n\n\n<p><a href=\"https://apps.apple.com/us/app/bandwidth/id490461369\" target=\"_blank\" rel=\"noopener\">Si ça vous branche, c’est par ici que ça se passe.</a></p>\n",

Parce que nous laissons tous des traces, qui mises bout à bout peuvent s’avérer très précises sur notre identité et nos comportements.</p>\n\n\n\n<p>J’ai commencé par vous expliquer ce qu’ils sont et comment fonctionnent ces courtiers en données, la manière dont ils s’y prennent pour faire de l’<a href=\"https://korben.info/incogni-enrichissement-des-donnees.html\" data-type=\"link\" data-id=\"https://korben.info/incogni-enrichissement-des-donnees.html\">enrichissement de données</a> ou encore comment cela peut se retourner contre vous au quotidien et quels problèmes cela peut vous causer (<a href=\"https://korben.info/incogni-cpf.html\" data-type=\"link\" data-id=\"https://korben.info/incogni-cpf.html\">arnaque à la formation CPF</a>, non-respect de votre vie privée …). Mais il y a une piste que je n’avais pas encore explorée et qui se rapporte aux voitures « modernes ».</p>\n\n\n\n<p>Vous allez me dire que ça y est, tonton Korben il a définitivement tous les voyants au rouge, il est sur la réserve. Et bien pas vraiment, comme je l’ai appris récemment <a href=\"https://foundation.mozilla.org/en/privacynotincluded/articles/its-official-cars-are-the-worst-product-category-we-have-ever-reviewed-for-privacy/\" data-type=\"link\" data-id=\"https://foundation.mozilla.org/en/privacynotincluded/articles/its-official-cars-are-the-worst-product-category-we-have-ever-reviewed-for-privacy/\" target=\"_blank\" rel=\"noreferrer noopener\">via une étude de Mozilla</a> pour son projet *Privacy Not Included (site qui analyse la sécurité de tous types d’objets connectés). Montez à bord, vous allez vite comprendre le rapport entre une voiture moderne, les data brokers et Incogni. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"480\" height=\"199\" src=\"https://kbn.im/incognidecembre\" alt=\"\"/></figure></div>\n\n\n<h2 class=\"wp-block-heading\">Voitures et data brokers</h2>\n\n\n\n<p>Nos voitures sont aujourd’hui dotées d’une énorme panoplie d’outils qui sont utilisés pour analyser nos comportements et l’environnement (extérieur comme intérieur) : capteurs, caméras, radars, micros, données de navigation, applications télématiques, etc. De quoi surveiller non seulement notre conduite, mais aussi tout ce qui l’entoure (la météo, nombres de personnes dans l’habitacle, vos déplacements, les endroits où vous vous rendez habituellement, ce que vous dites et faites dans le véhicule, filmer l’extérieur …).</p>\n\n\n\n<p>Cela fait déjà beaucoup d’informations privées récoltées, mais si cela reste dans les bases de données de votre constructeur ça limite le mal. Sauf qu’il a au moins 2 « petits » soucis. D’une part les bases de constructeurs auto sont de véritables passoires (plus de 2/3 ont été hackées dans les 3 dernières années) et surtout … la grande majorité (quasi 85%) des marques <strong>reconnaissent dans leurs CGU pouvoir récolter, partager et vendre vos données à des tiers</strong>. Et là vous voyez enfin le rapprochement avec les data brokers puisqu’ils font partie de ceux qui achètent ces données (tout comme les compagnies d’assurances). Les gouvernements n’ont même pas à passer à la caisse, plus de la moitié des marques disent qu’elles partageront leurs infos sur simple demande de ces derniers (heureusement en Europe c’est plus compliqué … pour l’instant).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"419\" src=\"https://korben.info/app/uploads/2023/11/donnes-voitures-incogni.jpg\" alt=\"Récoltes de données depuis votre voiture\" class=\"wp-image-155459\" style=\"width:800px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/11/donnes-voitures-incogni.jpg 800w, https://korben.info/app/uploads/2023/11/donnes-voitures-incogni-300x157.jpg 300w, https://korben.info/app/uploads/2023/11/donnes-voitures-incogni-768x402.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" /><figcaption class=\"wp-element-caption\"><a href=\"https://foundation.mozilla.org/en/privacynotincluded/articles/what-data-does-my-car-collect-about-me-and-where-does-it-go/\" data-type=\"link\" data-id=\"https://foundation.mozilla.org/en/privacynotincluded/articles/what-data-does-my-car-collect-about-me-and-where-does-it-go/\" target=\"_blank\" rel=\"noreferrer noopener\">Source</a></figcaption></figure></div>\n\n\n<p>Des données ultra-sensibles et un manque de sérieux en sécurité, qu’est ce qui pourrait mal tourner ? Vous imaginez la manière dont cela pourrait être détourné par des hackeurs ou les constructeurs eux-mêmes ? L’article source en cite plusieurs (je vous laisse lire ça dans l’article lié ci-dessus), dont une pour laquelle Ford a posé un brevet : faire en sorte que la voiture retourne automatiquement chez son concessionnaire en cas de non-remboursement du crédit. Et ouais ça va jusque là, Nissan mentionne même qu’ils peuvent enregistrer toute activité sexuelle ayant lieu dans la voiture … plus indiscret qu’une punaise de lit.</p>\n\n\n\n<p>Pour Mozilla, la masse d’informations récupérées est carrément hallucinante et va au-delà de tout type de matériel qu’ils ont pu tester jusqu’ici (donc pire que votre téléphone, enceinte connectée & Co), ils parlent même d’un niveau WTF. Et cela quel que soit le modèle de la voiture (entrée de gamme, SUV …). En 2021 cela représentait environ 60% des modèles, chiffre qui devrait atteindre les 90% d’ici 2026. Pas un seul des constructeurs n’arrive à atteindre les standards minimums. Quelques noms parmi les 25 marques passées au crible ? Tesla, Honda, Nissan, Kia, Renault (quasi la seule à respecter le RGPD pour le coup), Toyota, Volkswagen, Ford, BMW, Mercedes, Fiat …</p>\n\n\n\n<h2 class=\"wp-block-heading\">Incogni entre en jeu</h2>\n\n\n\n<p>On va faire attention aux sites avec lesquels nous partageons notre adresse physique, aux boutiques à qui nous donnons nos infos bancaires … mais qui va avoir le réflexe d’imaginer sa voiture comme un vecteur de risque ne serait-ce que potentiel ? C’est une piste qu’Incogni va sans doute explorer.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"501\" src=\"https://korben.info/app/uploads/2022/11/incogni-surfshark.jpg\" alt=\"Incogni Surfshark\" class=\"wp-image-131626\" srcset=\"https://korben.info/app/uploads/2022/11/incogni-surfshark.jpg 1024w, https://korben.info/app/uploads/2022/11/incogni-surfshark-300x147.jpg 300w, https://korben.info/app/uploads/2022/11/incogni-surfshark-768x376.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Comme vous le savez déjà, le travail d’Incogni est de contacter tous les data brokers qu’ils répertorient (presque 200 à l’heure actuelle) et leur demander de supprimer votre profil de leurs bases, et cela indéfiniment. Pour y parvenir Incogni va monitorer le suivit des demandes et surveiller que vous ne réapparaitrez pas dans le futur. Au vu du chantier que semble être le milieu de l’automobile, j’espère qu’ils vont s’y intéresser, car cela donnera de nouvelles pistes et de nouveaux brokers à ajouter à leur liste.</p>\n\n\n\n<p>Vous l’avez compris la fondation derrière le navigateur Firefox n’est pas tendre avec l’industrie automobile et leur manière de ne pas respecter la vie privée de leurs clients. Que pouvons-nous faire de notre côté ? Et bien pas grand-chose si ce n’est <a href=\"https://foundation.mozilla.org/fr/privacynotincluded/articles/car-companies-stop-your-huge-data-collection-programs-en/?utm_source=PNI&utm_campaign=23-PNI-Cars&utm_medium=FMO&utm_term=en&utm_content=blog_2\" data-type=\"link\" data-id=\"https://foundation.mozilla.org/fr/privacynotincluded/articles/car-companies-stop-your-huge-data-collection-programs-en/?utm_source=PNI&utm_campaign=23-PNI-Cars&utm_medium=FMO&utm_term=en&utm_content=blog_2\" target=\"_blank\" rel=\"noreferrer noopener\">signer leur pétition</a> et <strong>demander à Incogni de faire supprimer au plus vite nos infos</strong> dès qu’elles apparaissent dans un recoin de la toile. Ou alors rester sur un vieux modèle de voiture thermique sans modernité. La côte des 2CV et autres VW Golf 2 GTI d’occasion ne va pas baisser de si tôt 😉 </p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Découvrir l’offre d’Incogni</a></h2>\n",

Et c’est loin d’être un conte de fées. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-82414532\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>D’ailleurs, Friedling y fait un parallèle intéressant entre les explorateurs d’autrefois et les conquérants spatiaux d’aujourd’hui. Mais attention, on n’est pas dans un roman de science-fiction puisque le monsieur a été au cœur de l’action, en contribuant à l’élaboration de la première véritable stratégie de défense spatiale française. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"934\" height=\"1024\" src=\"https://korben.info/app/uploads/2023/12/Michel_Friedling_MSC_2019_cropped-934x1024.webp\" alt=\"\" class=\"wp-image-155825\" style=\"width:782px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/12/Michel_Friedling_MSC_2019_cropped-934x1024.webp 934w, https://korben.info/app/uploads/2023/12/Michel_Friedling_MSC_2019_cropped-274x300.webp 274w, https://korben.info/app/uploads/2023/12/Michel_Friedling_MSC_2019_cropped-768x842.webp 768w, https://korben.info/app/uploads/2023/12/Michel_Friedling_MSC_2019_cropped-1402x1536.webp 1402w, https://korben.info/app/uploads/2023/12/Michel_Friedling_MSC_2019_cropped-1869x2048.webp 1869w, https://korben.info/app/uploads/2023/12/Michel_Friedling_MSC_2019_cropped.webp 1920w\" sizes=\"(max-width: 934px) 100vw, 934px\" /></figure></div>\n\n\n<p><em>Photo : <a href=\"https://fr.wikipedia.org/wiki/Michel_Friedling#/media/Fichier:Michel_Friedling_MSC_2019_(cropped).jpg\" target=\"_blank\" rel=\"noopener\">Wikipedia</a>.</em></p>\n\n\n\n<p>Actuellement c’est donc plutôt un retour à la compétition stratégique, un Eldorado du 21e siècle convoité à la fois par les États et des acteurs privés audacieux (coucou SpaceX). Michel Friedling décrit cet espace comme un « Far-West » cosmique, une frontière sans loi où se cachent risques et menaces inimaginables. Il met en lumière comment, dans les siècles à venir, le vrai pouvoir sera aux mains de ceux qui tiendront les rênes de l’espace. </p>\n\n\n\n<p>Les États-Unis et la Chine sont actuellement en tête de cette course, mais la Russie, avec ses manœuvres récentes comme l’attaque d’un réseau de télécommunications par satellite lors de son conflit avec l’Ukraine, reste un acteur clé. Et n’oublions pas l’Inde et d’autres pays émergents, qui s’élancent avec ambition dans cette quête de suprématie spatiale.</p>\n\n\n\n<p>Même si l’auteur reprend l’histoire de la conquête spatiale dans les premières pages, ce livre n’est pas juste un récit de conquêtes spatiales qu’on connait déjà bien. Non, non, l’auteur avec son expérience impressionnante d’ingénieur et de stratège, nous fait surtout comprendre au fil des pages, les enjeux, stratégiques, économiques et militaires de l’espace. Ça se lit en quelques heures et vous aurez l’impression d’avoir eu un cours particulier avec le prof le plus cool de la galaxie.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https://korben.info/app/uploads/2023/12/IMG_3072-1024x768.webp\" alt=\"\" class=\"wp-image-155818\" srcset=\"https://korben.info/app/uploads/2023/12/IMG_3072-1024x768.webp 1024w, https://korben.info/app/uploads/2023/12/IMG_3072-300x225.webp 300w, https://korben.info/app/uploads/2023/12/IMG_3072-768x576.webp 768w, https://korben.info/app/uploads/2023/12/IMG_3072-1536x1152.webp 1536w, https://korben.info/app/uploads/2023/12/IMG_3072-2048x1536.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Pour ceux qui s’intéressent à la géopolitique, à la défense, ou qui sont juste fascinés par l’espace, « <strong>Commandant de l’Espace</strong> » est une mine d’or. C’est un livre écrit par quelqu’un qui a non seulement étudié l’espace, mais qui l’a vécu. Aujourd’hui CEO de <strong><a href=\"https://www.lookupspace.com/\" target=\"_blank\" rel=\"noopener\">Look Up Space</a></strong> (Rien à voir avec DiCaprio), Michel Friedling est à la pointe de ce qui se fait en SpaceTech française.

On parle d’ajustements de la fréquence d’image, de la vitesse d’obturation, de l’ISO, de la balance des blancs, de la résolution et j’en passe.

Vous pouvez les sauvegarder directement sur votre téléphone ou sur un disque externe. Cerise sur le gâteau, tous vos clips seront synchronisés avec DaVinci Resolve grâce au Blackmagic Cloud.</p>\n\n\n\n<p>Si vous travaillez avec DaVinci Resolve, la Blackmagic Camera se révèle être un allié précieux. Oubliez les heures passées à chercher des séquences dans les dossiers. Avec le <strong>Sync bin</strong> et d’autres outils, votre process de montage sera grandement accéléré puisque vous pourrez synchroniser plusieurs iPhones.</p>\n\n\n\n<p>Si vous souhaitez en savoir plus sur cette pépite, je vous invite à visiter le site <strong><a href=\"https://www.blackmagicdesign.com/fr/products/blackmagiccamera\" target=\"_blank\" rel=\"noopener\">Blackmagic Design</a></strong> et à télécharger l’application.</p>\n\n\n\n<p>Allez, tous à vos iPhones et faites moi des chefs-d’œuvre !</p>\n",

Je vous explique tout ça en détail dans ma vidéo.</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://www.leviia.com/object-storage/?mtm_campaign=korben\" target=\"_blank\" rel=\"noopener\">Testez Leviia gratuitement et sans engagement en cliquant ici</a></h2>\n\n\n\n<p>Longtemps adepte d’Amazon S3 pour mes backups, j’ai dû me rendre à l’évidence : entre l’augmentation des tarifs et le stockage de mes données aux États-Unis, il était temps de chercher ailleurs. C’est alors que j’ai découvert Leviia, un prestataire français offrant à la fois un Drive pour gérer vos documents et un service de stockage Object Storage (S3) idéal pour vos sauvegardes.</p>\n\n\n\n<p>J’ai testé Leviia et, franchement, c’est le jour et la nuit comparé à la concurrence. Leur interface utilisateur est d’une simplicité remarquable, rendant la création de buckets et la mise en place de sauvegardes en Object Storage (S3) accessibles à tous. Même pour un non-technicien, la migration depuis AWS S3 vers Leviia est un jeu d’enfant, réalisable en quelques secondes grâce à une compatibilité totale.</p>\n\n\n\n<p>Adopter Leviia, c’est aussi faire un choix éthique en faveur de la souveraineté numérique. Toutes les données sont stockées en France, un vrai plus pour ceux qui se préoccupent de la confidentialité de leurs informations.</p>\n\n\n\n<p>Leviia, c’est la combinaison d’une excellente performance, d’un prix attractif et d’un niveau de sécurité de haut vol. Pour le tarif, ils sont à 5,99 € / To par mois, ce qui est 80% moins cher qu’Amazon et moins cher que Wasabi.</p>\n\n\n\n<p>D’ailleurs, les données sont chiffrées et stockées dans trois data centers distincts, garantissant ainsi leur intégrité même en cas de sinistre.</p>\n\n\n\n<p>Dans cette nouvelle vidéo, je vous montre comment mettre en place une sauvegarde S3 de Leviia en utilisant Veeam, en respectant la règle 3-2-1-1-0. Vous verrez que sécuriser vos données n’a jamais été aussi simple.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"La sauvegarde 3-2-1 1-0 avec Leviia et Veeam\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/GFxLWaJe2hc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Et pour plus d’informations, n’hésitez pas à visiter le site de <a href=\"http://leviia.com/?mtm_campaign=korben\" target=\"_blank\" rel=\"noreferrer noopener\">Leviia</a>.

"description": "L'auteur, habitué à utiliser trois écrans pour son travail, critique le fait que les MacBook Air M2 et iMac M3 ne peuvent brancher qu'un seul écran. Il souligne la solution apportée par la technologie DisplayLink qui facilite la connexion entre les ordinateurs et les écrans, qu'ils soient connectés en HDMI, USB, Ethernet ou Wi-Fi. Il a investi dans un adaptateur OWC qui permet de brancher deux écrans 4K sur l'ordinateur. L'auteur apprécie la qualité d'image et la facilité d'installation de l'adaptateur, malgré son coût élevé. Il conclut que c'est un achat indispensable pour les utilisateurs d'ordinateurs Apple M1/M2/M3 qui rencontrent des problèmes avec leurs écrans externes.",

Leur modèle commercial repose sur la vente de puces et de licences pour leur technologie à des fabricants de matériel informatique, qui intègrent ensuite ces solutions dans leur matos.</p>\n\n\n\n<p>Ça faisait un moment que j’en avais entendu parler, mais jusqu’à présent, j’avais toujours réussi à contourner le problème. Mais avec mon iMac M3, c’était mort. J’ai donc investi dans <a href=\"https://amzn.to/3ulsHiR\" target=\"_blank\" rel=\"noopener\">cet adaptateur de marque OWC</a> et voici un petit article pour vous donner mon avis sur ce produit.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https://korben.info/app/uploads/2023/11/IMG_2793-copie-1024x768.webp\" alt=\"\" class=\"wp-image-155278\" srcset=\"https://korben.info/app/uploads/2023/11/IMG_2793-copie-1024x768.webp 1024w, https://korben.info/app/uploads/2023/11/IMG_2793-copie-300x225.webp 300w, https://korben.info/app/uploads/2023/11/IMG_2793-copie-768x576.webp 768w, https://korben.info/app/uploads/2023/11/IMG_2793-copie-1536x1152.webp 1536w, https://korben.info/app/uploads/2023/11/IMG_2793-copie-2048x1536.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Ce boitier qui fait 12 cm sur 6 cm se branche sur un port Thunderbolt ou USB-C et dispose de 2 ports HDMI permettant de brancher 2 écrans 4K sur l’ordinateur. Idéal donc pour les utilisateurs de Mac Apple Silicon M1, M2 ou encore M3. Mais il peut également fonctionner sur les PC si votre ordinateur est incapable de gérer plus de 1 écran externe.</p>\n\n\n\n<p>Techniquement, la solution de DisplayLink repose sur une combinaison de matériel et de logiciel. On y trouve donc une puce spéciale, conçue pour encoder et compresser les signaux vidéo. Lorsque l’utilisateur connecte un écran via un de ces adaptateurs, le signal vidéo de l’ordinateur est d’abord compressé via le logiciel DisplayLink puis une fois que le signal arrive aux écrans, la puce DisplayLink décompresse et reconstitue le signal vidéo, assurant que l’image affichée est fidèle à celle d’origine.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"947\" height=\"938\" src=\"https://korben.info/app/uploads/2023/11/SCR-20231118-bs6.webp\" alt=\"\" class=\"wp-image-155279\" srcset=\"https://korben.info/app/uploads/2023/11/SCR-20231118-bs6.webp 947w, https://korben.info/app/uploads/2023/11/SCR-20231118-bs6-300x297.webp 300w, https://korben.info/app/uploads/2023/11/SCR-20231118-bs6-150x150.webp 150w, https://korben.info/app/uploads/2023/11/SCR-20231118-bs6-768x761.webp 768w\" sizes=\"(max-width: 947px) 100vw, 947px\" /></figure></div>\n\n\n<p>Cette méthode de compression et décompression offre une grande flexibilité dans les configurations d’affichage, et garantit une qualité d’image élevée. Bref, c’est plutôt ingénieux et ça rend possible l’utilisation de plusieurs écrans via un seul port USB-C Thunderbolt. Et vous pouvez évidemment faire de la copie d’écran ou de l’affichage étendu comme si c’était nativement.</p>\n\n\n\n<p>En plus de sa fonctionnalité principale, l’adaptateur offre également une alimentation, permettant de recharger complètement un MacBook Pro ou MacBook Air M1 tout en faisant fonctionner deux écrans à partir d’un seul port. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"638\" height=\"634\" src=\"https://korben.info/app/uploads/2023/11/SCR-20231118-bx4.webp\" alt=\"\" class=\"wp-image-155281\" style=\"width:464px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/11/SCR-20231118-bx4.webp 638w, https://korben.info/app/uploads/2023/11/SCR-20231118-bx4-300x298.webp 300w, https://korben.info/app/uploads/2023/11/SCR-20231118-bx4-150x150.webp 150w\" sizes=\"(max-width: 638px) 100vw, 638px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-986953554\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Niveau prix, par contre, c’est assez cher, mais on paye la technologie qui se trouve dedans… Celui-ci est vendu un peu plus de 123 euros.

Je n’ai pas eu besoin de faire de paramétrage chelou et ça a même réglé les soucis de résolution que j’avais sur mes écrans externes. </p>\n\n\n\n<p>Pour la petite histoire, l’un d’entre eux est 4K, mais l’image se retrouvait être bien baveuse une fois branché en direct sur un Mac avec une puce Silicon. <a href=\"https://amzn.to/3ulsHiR\" target=\"_blank\" rel=\"noopener\">Avec ce boitier d’OWC</a>, ils ont été pris en charge par macOS aussi bien qu’un écran Apple officiel.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"723\" height=\"535\" src=\"https://korben.info/app/uploads/2023/11/SCR-20231118-bsa.webp\" alt=\"\" class=\"wp-image-155280\" style=\"width:617px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/11/SCR-20231118-bsa.webp 723w, https://korben.info/app/uploads/2023/11/SCR-20231118-bsa-300x222.webp 300w\" sizes=\"(max-width: 723px) 100vw, 723px\" /></figure></div>\n\n\n<p>Pour info, le boitier que j’ai choisi permet de brancher uniquement 2 écrans supplémentaires mais il existe d’autres boitier DisplayLink qui permettent d’en connecter beaucoup plus. <a href=\"https://amzn.to/3SMcH3m\" target=\"_blank\" rel=\"noopener\">Je vous laisse aller voir ça</a>.</p>\n\n\n\n<p>Bref, c’est vraiment un truc indispensable si vous êtes passé un ordinateur Apple M1 / M2 / M3 et que vous galérez avec vos écrans externes.

Et s’il y a un aspect que je n’ai pas encore abordé c’est comment un VPN peut s’adapter à la vague des nouveaux services récents, en priorités les fameuses IA (dont je parle à foison en ce moment).</p>\n\n\n\n<p>Pour commencer, je vais vous rappelez ce qu’est <a href=\"https://korben.info/chatgpt-openai.html\" data-type=\"link\" data-id=\"https://korben.info/chatgpt-openai.html\">ChatGPT</a> pour ceux du fond qui n’auraient pas suivi 😉 Il s’agit d’un chatbot qui utilise l’Intelligence artificielle pour répondre et échanger avec un humain à l’autre bout, sous la forme d’une conversation assez classique. Répondre à vos questions, faire de la traduction, pondre du code de programmation, résumer un texte ou écrire un livre <s>faire des traits d’humour</s> … il peut faire beaucoup de choses. Et, sans être parfait, il le fait plutôt bien et de mieux en mieux au fil des mois.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"585\" src=\"https://kbn.im/surfsharkchatgpt\" alt=\"\"/></figure>\n\n\n\n<p>Du coup si, comme moi, vous êtes un avide utilisateur de l’outil (c’est mon nouveau meilleur ami), un VPN va servir dans 2 cas. Déjà parce que ChatGPT n’est pas accessible depuis partout sur la planète. Car oui, certains pays l’ont tout simplement interdit. Surtout des pays qui ne vont pas vous surprendre (la Chine, l’Iran, la Corée du Nord ou la Russie notamment), mais aussi d’autres auquel nous n’aurions pas pensé, comme l’Italie en ce moment. Si vous habitez/voyagez, dans ces endroits, un VPN va vous permettre d’y accéder malgré tout. Rappelons aussi qu’il existe encore un flou autour du respect des droits RGPD de l’outil, ce qui pourrait à un moment l’amener à se faire bloquer chez nous.</p>\n\n\n\n<p>Le second intérêt est de cacher votre réelle identité numérique à l’outil d’OpenAI. Car les discussions que vous avez avec l’IA peuvent souvent en dire beaucoup sur vous. En temps normal il va pouvoir « coupler » vos discussions ChatGPT avec votre adresse IP, vos cookies, votre email ou vos noms (donnés lors de la création du compte), voir vos données bancaires (si vous prenez l’option payante). Cela commence à faire pas mal de données.</p>\n\n\n\n<p>Surtout si dans vos conversations avec l’IA vous lui posez des questions concernant des soucis de santé, des pensées, lui demander un plan alimentaire ou des séries d’exercices, quelles activités pratiquer dans telle ville, etc. Et ne riez pas, mais certains rentrent très vite dans le mood de lui partager leurs réflexions les plus intimes, surtout qu’il est possible de lui parler directement (<a href=\"https://korben.info/talk-to-chatgpt.html\" data-type=\"link\" data-id=\"https://korben.info/talk-to-chatgpt.html\">Talk to ChatGPT</a>). Vous avez vu le film Her ? Et bien ChatGPT peut très facilement devenir assez proche de vous, ou tout du moins savoir sur quoi vous êtes en train de travailler, ce que vous mettez en place dans votre quotidien & co.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"480\" height=\"480\" src=\"https://media.giphy.com/media/sxvRgctowJHL5c0vzi/giphy.gif\" alt=\"\" style=\"aspect-ratio:1;width:246px;height:auto\"/></figure></div>\n\n\n<p><a href=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768&url_id=1511\" data-type=\"link\" data-id=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768&url_id=1511\" target=\"_blank\" rel=\"noreferrer noopener\">Surfshark VPN</a> va aider à cacher tout cela et à protéger votre vie privée. Grâce à leurs 3200 serveurs répartis dans plus de 100 pays, l’adresse IP rotative automatiquement, le chiffrement du trafic de bout en bout ou la création d’identité alternative (avec l’offre <a href=\"https://korben.info/articles/surfshark-one\" data-type=\"link\" data-id=\"https://korben.info/articles/surfshark-one\">Surfshark One</a>), sont autant d’options qui vont brouiller les pistes.</p>\n\n\n\n<p>J’en profite pour rappeler quelques-uns des intérêts principaux de Surfshark :</p>\n\n\n\n<ul>\n<li>Non-conservation des logs (audité par des boites sérieuses)</li>\n\n\n\n<li>Protection contre les fuites DNS</li>\n\n\n\n<li>Bouton Kill switch</li>\n\n\n\n<li>Mode camouflage</li>\n\n\n\n<li>MultiHop dynamique</li>\n\n\n\n<li>GPS-Spoofing pour Android</li>\n\n\n\n<li>Disponible sur tous les systèmes d’exploitation, en version mobile, sur navigateur, etc.</li>\n</ul>\n\n\n\n<p>Bref, quel que soit votre moyen de vous connecter aux outils d’intelligence artificielle, il vous protègera. Et pas que vous d’ailleurs puisque l’autre point fort de l’outil est de protéger un nombre illimité d’appareils en simultané. Toute la famille va pouvoir discuter avec son propre chatbot personnel. C’est quand même mieux que de se parler en vrai hein, on est en 2023 après tout. Les relations humaines c’est soooo 20e siècle.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https://korben.info/app/uploads/2023/01/robot-1024x683.webp\" alt=\"\" class=\"wp-image-132440\" style=\"width:700px\" srcset=\"https://korben.info/app/uploads/2023/01/robot-1024x683.webp 1024w, https://korben.info/app/uploads/2023/01/robot-300x200.webp 300w, https://korben.info/app/uploads/2023/01/robot-768x512.webp 768w, https://korben.info/app/uploads/2023/01/robot.webp 1536w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>En plus c’est toujours la bonne période pour <strong>profiter de l’offre à -86% sur leur abonnement 2 ans</strong> (+ 3 mois offerts). Du coup vous allez payer moins de 65€ (TVA comprise) pour 27 mois d’utilisation (2.4€/mois) ! Ou 90€ pour 28 mois si vous prenez l’offre Surfshark One avec le combo antivirus/alertes/identité alternative & co en plus. Vous pouvez même payer en cryptomonnaies, maintenant que ça remonte un peu.</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768&url_id=1511\" data-type=\"link\" data-id=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768&url_id=1511\" target=\"_blank\" rel=\"noreferrer noopener\">Découvrir Surfshark VPN !</a></h2>\n",

La première, c’est la liste des conseils et des problèmes détectés. La deuxième, c’est un état des lieux de vos composants, pour vérifier que tout est bien configuré et à jour. Et la dernière, c’est une série de graphiques pour visualiser comment votre système réagit au fil du temps.</p>\n\n\n\n<p>Un des atouts majeurs de UserDiag, c’est surtout son intégration avec <a href=\"https://www.hwinfo.com/\" target=\"_blank\" rel=\"noopener\">HWiNFO</a>, un outil de monitoring en temps réel que vous connaissez probablement. Grâce à lui, UserDiag peut vous fournir des relevés précis des tensions, des fréquences et des températures du système.

Cela fait des mois (années ?) que vous pensez à prendre un VPN parce que c’est vraiment devenu un incontournable de la sécurité numérique. Sauf que vous ne passez jamais à l’action parce que … la flemme quoi. Alors aujourd’hui voici un petit rappel et coup de pouce pour vous aider à franchir le pas.</p>\n\n\n\n<p>C’est bientôt le retour du Black Friday (fin novembre), mais si vous savez cette fête archicommerciale venue des US et qui a lieu le lendemain de la Thanksgiving ? Et comme chaque année Surfshark met en place une promo spéciale un mois avant l’event. Vous pourrez ainsi <a href=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" data-type=\"link\" data-id=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\">profiter de max -86% sur le tarif habituel du VPN avec en plus de 3 à 5 mois offerts</a> (selon le pack). Soit, pour la version VPN seule, moins de 65 € pour 27 mois. Plutôt pas mal !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" fetchpriority=\"high\" width=\"1000\" height=\"124\" src=\"https://kbn.im/surfsharkvpnpromoblackfriday\" alt=\"\" style=\"aspect-ratio:8.064516129032258;width:699px;height:auto\"/></figure></div>\n\n\n<p>Surtout que l’on parle ici d’un outil qui est désormais régulièrement classé parmi les meilleurs de sa catégorie. Quand j’en parlai en 2020, il faisait encore partie des petites jeunes du game qui devait faire ses preuves, mais c’est maintenant terminé. Il est largement plébiscité, notamment au niveau de la sécurité qu’il offre :</p>\n\n\n\n<ul>\n<li>non-conservation de vos journaux d’activités</li>\n\n\n\n<li>chiffrement de bout en bout AES-256-GCM</li>\n\n\n\n<li>support des protocoles IKEv2/IPsec, OpenVPN ou Wireguard</li>\n\n\n\n<li>protection contre les fuites IPv4</li>\n\n\n\n<li>Authentification 2FA</li>\n\n\n\n<li>bouton kill switch</li>\n\n\n\n<li>fonctionnalité Multihop</li>\n\n\n\n<li>tunnelisation fractionnée</li>\n\n\n\n<li>rotation d’IP</li>\n</ul>\n\n\n\n<p>Vous trouverez plus d’infos sur ces différents points, ainsi que l’innovation Surfshark Nexus, dans mes articles précédents (je vieillis, mais j’essaye de ne pas trop radoter). Je le mentionne aussi rapidement, mais comme tout bon VPN il vous permet les actions classiques. Comme d’accéder aux Wi-Fi publics de manière sécurisée, éviter la censure s’il y en a dans le pays que vous visitez ou encore comparer les prix de certains achats pour faire des économies (billets d’avion ou de train, etc.).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"1000\" height=\"514\" src=\"https://korben.info/app/uploads/2023/10/surfshark-promo-ete-2023.webp\" alt=\"\" class=\"wp-image-154791\" style=\"aspect-ratio:1.9455252918287937;width:656px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/10/surfshark-promo-ete-2023.webp 1000w, https://korben.info/app/uploads/2023/10/surfshark-promo-ete-2023-300x154.webp 300w, https://korben.info/app/uploads/2023/10/surfshark-promo-ete-2023-768x395.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Son autre point fort est la facilité d’utilisation et sa flexibilité. Que vous soyez sur n’importe quel OS desktop (Windows, macOS/Linux) ou mobile (Android, iOS), que vous utilisiez n’importe quel navigateur (Chrome/Brave, Firefox, Edge …) ou type de machines (Smart TV, consoles de jeu, tablette, routeur, home assistant …), il est adapté. D’autant plus qu’<strong>il ne vous limite pas en nombre d’appareils à connecter simultanément sur un compte</strong>, c’est illimité ! De quoi protéger toute la famille et permettre à tout le monde d’accéder au catalogue Netflix (ou autres) de son choix 😉 Le tout sans pubs, parce qu’on ne va pas se priver d’une cerise de plus sur le cake.</p>\n\n\n\n<p>Et pas besoin de vous inquiéter du débit en fonction du pays ou vous vous trouvez puisqu’il y a toujours un/des serveur(s) à proximité (désormais dans une grosse centaine de pays). De plus ça fait maintenant plusieurs mois que Surfshark a commencé de renouveler son parc de 3200+ serveurs (tous 100% RAM), passant ces derniers d’une vitesse de 1Gb/s à 10Gb/s.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"1000\" height=\"560\" src=\"https://korben.info/app/uploads/2023/10/surfshark-vpn-black-friday-2023.webp\" alt=\"\" class=\"wp-image-154792\" style=\"aspect-ratio:1.7857142857142858;width:578px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/10/surfshark-vpn-black-friday-2023.webp 1000w, https://korben.info/app/uploads/2023/10/surfshark-vpn-black-friday-2023-300x168.webp 300w, https://korben.info/app/uploads/2023/10/surfshark-vpn-black-friday-2023-768x430.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Vous pouvez aussi choisir les versions One et One+ si vous préférez une boite à outils complète centralisée dans un même outil. Le <a href=\"https://korben.info/articles/surfshark-one\" data-type=\"link\" data-id=\"https://korben.info/articles/surfshark-one\">pack Surfshark One</a> (3,07 €/mois + 4 mois gratuits) vous donne accès en plus à un antivirus, un moteur de recherche privé, un système d’alerte et depuis peu la possibilité de <a href=\"https://korben.info/surfshark-one-se-dote-de-loption-creation-didentite-alternative-promo-rentree-2023.html\" data-type=\"link\" data-id=\"https://korben.info/surfshark-one-se-dote-de-loption-creation-didentite-alternative-promo-rentree-2023.html\">créer des identités alternatives</a>. Quant à la version One+ (4.58 €/mois + 5 mois offerts) elle ajoute le service Incogni, dont j’ai parlé plusieurs fois. À vous de choisir la sauce à mettre sur vos frites.</p>\n\n\n\n<p>Bref, quel que soit votre profil il y a de quoi faire avec Surfshark. Et avec <strong>cette offre Black Friday 2023 à max -86%</strong> + 3 à 5 mois offerts, c’est l’occasion rêvée d’enfin protéger un peu mieux vos activités numériques.

C’est simple : <a href=\"https://amzn.to/40kXvwa\" target=\"_blank\" rel=\"noopener\">le mélange des deux</a> ! Un jeu 2D qui reprend les bases du gameplay d’origin(e), mais dans un enrobage moderne, de nouvelles idées fraîches et une composante multijoueurs. Ça tombe bien c’est ce que promet <a href=\"https://amzn.to/40kXvwa\" target=\"_blank\" rel=\"noopener\">Sonic Superstars</a> !</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Sonic Superstars - Launch Trailer\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/MsL9pKdJ1A8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Fang est de retour et fait équipe avec la mystérieuse Trip, pour épauler Dr Eggman dans son plan diabolique ! Pour l’arrêter, dès le départ on peut choisir Sonic, Tails, Knuckles et Amy, chaque personnage ayant ses spécificités habituelles, à quelques détails près. 😉 Et puis on débloque un nouveau personnage quand on finit le jeu. 🤫 La structure de l’aventure est similaire aux grands classiques 2D, avec les zones découpées en actes, les boss, les stages bonus. On est en terrain connu, sauf que cette fois-ci, première chose qui frappe : le rendu est en 3D !</p>\n\n\n\n<p>C’est mignon comme tout, les designs sont de bon goût, c’est coloré, les animations sont légèrement statiques mais c’est très agréable à voir. Dans chacun des niveaux, l’ambiance est top et l’action est toujours lisible ! 🙂 Les musiques, à une ou deux exceptions près, sont réussies, et <strong>les contrôles sont très bons</strong>, c’est réactif, super maniable… Au top. 🙂 </p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-4.webp\" alt=\"\" class=\"wp-image-154847\" srcset=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-4.webp 1000w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-4-300x169.webp 300w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-4-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Les zones de jeu sont vastes, avec plein de chemins possibles à explorer, c’est un plaisir de parcourir les différents mondes, éviter les pièges tout en éclatant un maximum de badniks ! Seule ombre au tableau : les stages bonus, trop nombreux et pas ultra intéressants, nous coupent régulièrement l’herbe sous le pied. Il en existe de plusieurs sortes : les grands anneaux qui cachent une émeraude du chaos (gameplay bof mais nouveaux pouvoirs à débloquer !), les portails qui apparaissent quand on touche un point de sauvegarde avec plus de 50 anneaux (gameplay cool mais récompense bof), et enfin des warpzones qui nous transportent ailleurs dans la map (gameplay inexistant et résultat aléatoire).</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2017238302\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Disons que c’est pas nul, mais mal dosé. L’exploration n’est pas toujours récompensée comme il se doit. On s’en fout un peu de récupérer des médailles. Pareil pour les boss : ils sont globalement sympa, mais certaines phases sont un peu longues (on doit attendre le bon moment pour attaquer), puis parfois on se fait <em>one shot</em> sans avoir pu prévoir la prochaine offensive, et là, on doit se retaper toutes les animations depuis le début. Un peu agaçant. 😓</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-5.webp\" alt=\"\" class=\"wp-image-154845\" srcset=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-5.webp 1000w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-5-300x169.webp 300w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-5-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>En dehors de cela, le fun est bien présent. Chaque zone propose des nouveautés de gameplay ou des petits twists cools ! Nouveauté : chaque Chaos Emeralds nous offre un pouvoir (remonter les cascades d’eau, voir des objets invisibles, faire pousser un haricot géant…), et même si là aussi ça aurait pu être mieux dosé et + malin, c’est tout de même vraiment chouette, ça apporte une certaine fraîcheur ! Revenir sur certaines zones avec de nouveaux pouvoir est toujours intéressant. 😉</p>\n\n\n\n<p>On peut jouer jusqu’à 4 joueurs, en faisant les niveaux en coop, ou bien sur différents jeux compétitifs où l’on incarne des robots. Bon, la compète c’est rigolo quelques minutes, ça se joue en ligne et tout, mais ça reste du mini jeu basique, ça ne va pas très loin. On peut personnaliser nos robots en échangeant les médailles qu’on trouve partout dans l’aventure principale, voilà, c’est à ça que ça sert les médailles… Pas fou-fou.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-2.webp\" alt=\"\" class=\"wp-image-154846\" srcset=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-2.webp 1000w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-2-300x169.webp 300w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-2-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>En revanche, on peut faire l’aventure en coop, ça rappelle les bons souvenirs de Sonic 2 avec l’apparition de Tails ! Cette fois-ci, on peut être jusqu’à 4 joueurs, et la caméra ne se contente pas de suivre Sonic. 😀 Bon, si on veut explorer / se balader chacun comme bon nous semble, ça va pas le faire. Mais si on essaie de se coordonner, c’est sympa ! Il faut quand même être honnête, entre la vitesse, le nombre de pièges, et la construction même des niveaux, il y a des jeux qui sont + adaptés à ce genre d’expérience. Il faut voir ça comme un bonus. Je préfère le jeu solo.</p>\n\n\n\n<p>J’ai cité pas mal de défauts ou d’éléments un peu bancals, alors que vraiment j’ai beaucoup apprécié ce voyage ! C’est super agréable, fun, amusant, dépaysant… Y a plein de bonnes idées, c’est un jeu vraiment frais, mais ce n’est pas parfait. Les fans de Sonic seront comblés. Les fans de plate-formes passeront un super moment. Je lui donne <strong>7 hérissons 🦔/10 </strong>!</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">Acheter Sonic Superstars sur <a href=\"https://amzn.to/3MnxMNT\" target=\"_blank\" rel=\"noopener\">Switch</a>, <a href=\"https://amzn.to/3FG5omh\" target=\"_blank\" rel=\"noopener\">PC</a>, <a href=\"https://amzn.to/3sbDhs0\" target=\"_blank\" rel=\"noopener\">PS4</a>, <a href=\"https://amzn.to/40ihsDJ\" target=\"_blank\" rel=\"noopener\">PS5</a>, <a href=\"https://amzn.to/3QMvPND\" target=\"_blank\" rel=\"noopener\">Xbox</a></h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-3.webp\" alt=\"\" class=\"wp-image-154853\" srcset=\"https://korben.info/app/uploads/2023/10/Sonic-Superstars-3.webp 1000w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-3-300x169.webp 300w, https://korben.info/app/uploads/2023/10/Sonic-Superstars-3-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n",

Non seulement cela améliorerait votre expérience de jeu, mais vous pourrez également <strong>mapper les contrôles tactiles personnalisés</strong> sur votre clavier pour une expérience de jeu encore plus fluide.</p>\n\n\n\n<p>À l’origine, PlayCover a été conçu pour faire tourner le célèbre jeu <strong>Genshin Impact</strong>. Cependant, il a rapidement évolué pour prendre en charge <strong>d’autres applications</strong>. Cela signifie que vous n’êtes pas limité à l’utilisation de PlayCover uniquement pour les jeux. Vous pouvez également l’utiliser pour exécuter d’autres applications iOS sur votre Mac ! Gain de temps garanti dans vos process !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"942\" height=\"518\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230918-ghv.webp\" alt=\"\" class=\"wp-image-154074\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230918-ghv.webp 942w, https://korben.info/app/uploads/2023/09/SCR-20230918-ghv-300x165.webp 300w, https://korben.info/app/uploads/2023/09/SCR-20230918-ghv-768x422.webp 768w\" sizes=\"(max-width: 942px) 100vw, 942px\" /></figure></div>\n\n\n<p>Comme mentionné précédemment, PlayCover est <strong>compatible uniquement avec les Macs Apple Silicon</strong> (M1, M1 Pro, M1 Max, M1 Ultra, M2 et prochainement M3).

Si vous ne connaissez pas encore Homebrew, c’est un gestionnaire de paquets pour macOS qui facilite l’installation et la désinstallation des logiciels. Pour installer PlayCover, il vous suffit d’exécuter la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>brew install --cask PlayCover/playcover/playcover-community</code></pre>\n\n\n\n<p>Ensuite, il vous suffira de trouver une application iOS au format IPA (sans virus dedans), de la glisser-déposer dans l’application et c’est parti ! D’ailleurs si vous connaissez de bons dépôts d’IPA pas vérolés, ça m’intéresse.</p>\n\n\n\n<p>Bonne exploration et amusez-vous bien !</p>\n",

Et aujourd’hui, je vous présente <strong><a rel=\"noopener\" href=\"https://github.com/lllyasviel/Fooocus\" target=\"_blank\">Fooocus</a></strong>, qui va vous permettre de générer de jolies images avec l’IA. Ce logiciel libre est<strong> basé sur Gradio</strong> et reprend le meilleur des concepts de Stable Diffusion et Midjourney tout en étant hors ligne, open source, gratuit, le tout sans réglages manuels à se taper la tête contre les murs.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-857972565\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>L’outil est ainsi capable de générer des images photo réalistes à partir d’un simple prompt, tout en procédant à un raffinement automatique afin d’éviter tout ce qui est apparences trop lisses ou « plastiques ». </p>\n\n\n\n<p>Voici un exemple fait à l’arrache : </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" fetchpriority=\"high\" width=\"1000\" height=\"645\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230917-ioqk.webp\" alt=\"\" class=\"wp-image-154065\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230917-ioqk.webp 1000w, https://korben.info/app/uploads/2023/09/SCR-20230917-ioqk-300x194.webp 300w, https://korben.info/app/uploads/2023/09/SCR-20230917-ioqk-768x495.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Fooocus est hyper simple à installer et nécessite moins de 3 clics pour être opérationnel.

Même un ordinateur portable bas de gamme, équipé d’une Nvidia 3060, peut faire le job.</p>\n\n\n\n<p>Ça peut s’installer sous Windows et Linux et les modèles de diffusion sont téléchargés automatiquement via le lanceur de Fooocus.

Conçu pour aider à la conception de designs pour les applications, les sites web et bien plus encore, il s’avère être un outil extrêmement intuitif. En quelques clics, vous placez vos éléments de design, des boutons, des images et d’autres composants, puis vous laissez Penpot générer le rendu du prototype et même le code CSS pour vous. Oui, directement du code CSS à intégrer dans vos projets web sans forcement avoir besoin de maitriser tous les paramètres de CSS.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"543\" src=\"https://kbn.im/penpot23\" alt=\"\"/></figure></div>\n\n\n<p>L’une des grosses mises à jour récente de Penpot c’est son support du « flex layout ». Pour ceux qui ne sont pas familiers avec le terme, le flex layout (ou flexbox) est une norme CSS qui permet aux éléments de s’adapter automatiquement à la taille de l’écran ou de la fenêtre. Imaginez un bouton dont le texte change : au lieu de déborder, avec flexbox, le bouton s’agrandit. Penpot vous permet ainsi de créer des designs responsives, qui s’adaptent à toutes les tailles d’écran.</p>\n\n\n\n<p>Evidemment, pour vous faire découvrir tout ça en détails, je vous ai concocté une vidéo tutoriel très détaillée de <a href=\"https://penpot.app/layout?mtm_campaign=Flex-Layout-korbenarticle\" target=\"_blank\" rel=\"noopener\"><strong>Flex Layout</strong></a>, pour que vous puissiez bien comprendre son fonctionnement et l’utiliser ensuite dans vos propres projets de sites web ou d’applications mobiles. J’espère que ça vous plaira !</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Découvrez Flex Layout de Penpot, l'outil libre de design et de prototypage de vos apps.\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/XqiJwwjA-3w?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p><a href=\"https://penpot.app/layout?mtm_campaign=Flex-Layout-korbenarticle\" target=\"_blank\" rel=\"noopener\">A découvrir ici !</a></p>\n",

Vous pouvez également lancer l’enregistrement en aide manuel (<em>manual</em>) sur un live déjà lancé ou en mode automatique (<em>automatic</em>) pour commencer un enregistrement automatiquement quand un streamer passe en live. Comme ça vous laissez tourner, vous partez au boulot et vous aurez le fichier vidéo du stream à la fin de la journée.</p>\n\n\n\n<p>Le logiciel commencera alors à chercher le live en cours et commencera l’enregistrement dès qu’il trouve quelque chose. Les vidéos et les audios enregistrés seront sauvegardés dans le dossier par défaut, qui est généralement le dossier d’installation du logiciel. Vous pouvez également utiliser ffmpeg en paramètre pour forcer une conversion directement au format MP4 (sinon, ça peut se faire à la fin).</p>\n\n\n\n<p>Et voilà ! C’est aussi simple que cela. Vous pouvez maintenant enregistrer vos sessions de streaming en direct sur TikTok et les conserver pour les visionner plus tard, en faire des montages, ou les partager avec vos amis.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1685761765\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Amusez-vous bien et promis, vous me suivez sur TikTok ?

D’ailleurs, si vous débutez avec Docker, j’ai fait une vidéo d’initiation pour débutants pour mes <a href=\"https://patreon.com/korben\" target=\"_blank\" rel=\"noopener\">Patreons</a> que je vous offre à la fin de cet article.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1104015659\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Mais pour qu’une image Docker soit OK, il faut qu’elle ait été un minimum optimisé. Et ce n’est pas forcement instinctif, surtout quand on débute. </p>\n\n\n\n<p>C’est pourquoi , je vous présente un outil aussi magique qu’un Fabien Olicard sous Caprisun, qui va non seulement vous permettre de comprendre la structure de vos images Docker de fond en comble, mais également d’optimiser leur taille et de libérer cet espace disque précieux dont on manque tous sur nos ordis. Cet outil c’est <strong>Dive</strong>.</p>\n\n\n\n<p>Imaginez que vous êtes développeur ou administrateur système, et que vous devez régulièrement manipuler et gérer des images Docker. Vous savez qu’il est crucial d’optimiser ces images pour réduire leur taille et ainsi améliorer leur efficacité, mais vous ne savez pas par où commencer. Dive est là pour vous aider ! Avec cet outil, vous pourrez analyser facilement vos images Docker, découvrir les modifications effectuées à l’intérieur chaque couche et optimiser leur taille de manière efficace.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1734\" height=\"1083\" src=\"https://korben.info/app/uploads/2023/09/demo-3.gif\" alt=\"\" class=\"wp-image-154020\"/></figure></div>\n\n\n<p>Tout d’abord, il suffit de remplacer la commande « <em>docker build</em> » par « <em>dive build</em> » pour analyser l’efficacité et l’espace gaspillé de votre image Docker. </p>\n\n\n\n<pre class=\"wp-block-code\"><code>dive <tag/id/digest de votre image></code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2005420352\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Dive prend en charge plusieurs <strong>sources d’image et moteurs de conteneurs</strong> (à l’heure actuelle, Docker et Podman). Pour l’installation, Dive est disponible pour <strong>Ubuntu/Debian, RHEL/Centos, Arch Linux, Mac et Windows</strong>.</p>\n\n\n\n<p>Pour l’installer sous macOS :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>brew install dive</code></pre>\n\n\n\n<p>Pour l’installer sous Linux (Ubuntu / Debian) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>export DIVE_VERSION=$(curl -sL \"https://api.github.com/repos/wagoodman/dive/releases/latest\" | grep '\"tag_name\":' | sed -E 's/.*\"v([^\"]+)\".*/\\1/')\n\ncurl -OL https://github.com/wagoodman/dive/releases/download/v${DIVE_VERSION}/dive_${DIVE_VERSION}_linux_amd64.deb\n\nsudo apt install ./dive_${DIVE_VERSION}_linux_amd64.deb</code></pre>\n\n\n\n<p>Intégrer Dive dans votre processus de <strong>CI (intégration continue)</strong> est également possible en utilisant la variable d’environnement <code>CI=true</code>. Vous pouvez même configurer des règles dans un fichier <code>.dive-ci</code> pour automatiser certaines vérifications et optimisations de vos images Docker.</p>\n\n\n\n<p>Naviguer dans Dive est un jeu d’enfant grâce aux <strong>raccourcis clavier</strong>. Vous pourrez explorer les couches de vos images Docker, filtrer les fichiers, gérer les paramètres spécifiques à chaque couche et personnaliser l’interface utilisateur en créant un fichier de configuration.</p>\n\n\n\n<p>Pour en savoir plus sur Dive et ses fonctionnalités, je vous invite à consulter le dépôt GitHub officiel <a href=\"https://github.com/wagoodman/dive\" target=\"_blank\" rel=\"noopener\">ici</a>. Vous y trouverez toutes les informations nécessaires pour maîtriser cet outil fantastique, ainsi que des exemples et des astuces pour optimiser vos images Docker comme un pro.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1925505183\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p><strong>Bonne optimisation à tous !</strong></p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Installer Docker sur Linux [Guide pas à pas]\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/9ml-cHpwdXQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n",

Les 60 niveaux proposés augmentent progressivement en difficulté, ajoutant des couches de complexité à mesure que vous progressez.</p>\n\n\n\n<p>L’interface minimaliste permet aux joueurs de se concentrer entièrement sur le puzzle, éliminant toute distraction inutile et vous avez même de la musique sympa pour vous accompagner.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"494\" src=\"https://korben.info/app/uploads/2023/10/SCR-20231025-b89-1024x494.png\" alt=\"\" class=\"wp-image-154725\" srcset=\"https://korben.info/app/uploads/2023/10/SCR-20231025-b89-1024x494.png 1024w, https://korben.info/app/uploads/2023/10/SCR-20231025-b89-300x145.png 300w, https://korben.info/app/uploads/2023/10/SCR-20231025-b89-768x370.png 768w, https://korben.info/app/uploads/2023/10/SCR-20231025-b89.png 1182w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Bref, la beauté de Blocks réside dans sa capacité à offrir un équilibre parfait entre la détente et le défi cérébral.

Il prend en charge diverses éditions, langues et versions des jeux SCUMM, GrimE, Star Wars, Indiana Jones et autres jeux LucasArts. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1821964724\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Vous pouvez télécharger la dernière version de DREAMM en allant <a href=\"https://aarongiles.com/dreamm/\" target=\"_blank\" rel=\"noopener\">sur ce site</a>.</p>\n\n\n\n<p>Lorsque vous lancez <strong>DREAMM</strong>, vous accédez au <strong>Game Manager</strong> pour ajouter, configurer et exécuter les jeux. L’interface principale montre les icônes des jeux installés, et vous pouvez ajouter de nouveaux jeux à tout moment, sauf pendant une opération d’ajout en cours. Pour configurer et exécuter un jeu, cliquez simplement sur son icône ou naviguez avec les touches fléchées.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"809\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230911-lqe-1024x809.webp\" alt=\"\" class=\"wp-image-154002\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230911-lqe-1024x809.webp 1024w, https://korben.info/app/uploads/2023/09/SCR-20230911-lqe-300x237.webp 300w, https://korben.info/app/uploads/2023/09/SCR-20230911-lqe-768x607.webp 768w, https://korben.info/app/uploads/2023/09/SCR-20230911-lqe.webp 1392w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Sélectionnez un jeu et accédez à l’écran de configuration et de lancement, où des informations sur la compatibilité sont disponibles dans la zone d’état. Vous pouvez gérer l’installation en cliquant sur l’onglet <strong>MANAGE</strong>, où vous pourrez vérifier les fichiers, désinstaller le jeu et accéder aux données pertinentes du jeu.</p>\n\n\n\n<p>Avec DREAMM, vous pouvez facilement explorer et configurer les dossiers de jeux, ainsi que les options audio et vidéo. Vous pouvez également contrôler la taille de l’écran du gestionnaire de jeux, basculer entre le mode fenêtré et plein écran et ajuster la taille avec des raccourcis clavier.</p>\n\n\n\n<p>DREAMM nécessite les fichiers d’origine pour exécuter un jeu. Il prend en charge les images disque de disquettes (IMG, IMA, VFD) et de CD-ROM (ISO, CUE/BIN, MDS/MDF, CCD/IMG). Pour installer à partir d’images disque, sélectionnez toutes les images et faites-les glisser sur la fenêtre de DREAMM. Si vous possédez les disquettes ou CD-ROM d’origine, vous pouvez également les installer à partir de ces supports. Et si vous n’avez pas les jeux d’origine, sachez qu’il y a des démos sur Archive.org au moins pour tester.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"809\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230911-lrb-1024x809.webp\" alt=\"\" class=\"wp-image-154003\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230911-lrb-1024x809.webp 1024w, https://korben.info/app/uploads/2023/09/SCR-20230911-lrb-300x237.webp 300w, https://korben.info/app/uploads/2023/09/SCR-20230911-lrb-768x607.webp 768w, https://korben.info/app/uploads/2023/09/SCR-20230911-lrb.webp 1392w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Lors de l’installation d’un jeu via DREAMM, choisissez le lecteur C: comme cible et laissez l’installateur faire son travail. DREAMM détecte et transfère les jeux installés.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-908113151\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>DREAMM émule vraiment les jeux au niveau du CPU et nécessite les fichiers exécutables originaux. Son concurrent ScummVM n’émule pas mais est une réécriture complète issu d’un reverse engineering. Donc le rendu n’est pas fidèle aux jeux d’origine, alors qu’avec DREAMM c’est 100% identique à l’expérience que vous avez pu avoir étant jeune. Mais les 2 outils fonctionnent très bien, on est sur du chipotage à ce niveau, il faut bien le reconnaitre.</p>\n\n\n\n<p>DREAMM gère également les contrôles de joystick. Utilisez Alt+U⌘U ou F12 pour récupérer le contrôle de la souris si nécessaire.</p>\n\n\n\n<p>Voilà, j’espère que ça vous aura donné envie de vous refaire un Indiana Jones ou de replonger dans un bon vieux Sam & Max.</p>\n",

Oui, oui, vous vous reconnaissez, ceux qui ne font jamais leurs mises à jour Windows et qui disent en frimant : « <em>Oh moi, j’ai pas besoin d’antivirus, car je sais ce que je fais.</em>« </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1878573442\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>LOL !</p>\n\n\n\n<p>Et bien, aujourd’hui, je vais vous parler d’un super-héros qui pourrait bien vous sauver la vie, enfin, celle de votre ordinateur : <strong>ESET SysRescue Live</strong>.</p>\n\n\n\n<p>Imaginez que vous êtes en train de travailler sur un projet important et, soudain, votre ordinateur commence à agir bizarrement. Les performances ralentissent et vos fichiers deviennent inaccessibles. Vous réalisez que votre ordinateur a été infecté par le dernier malware. Vous essayez tous les logiciels antivirus possibles, mais rien ne semble fonctionner. </p>\n\n\n\n<p>Alors, que faire à part m’envoyer un message sur Facebook si vous êtes ma mère ? C’est là qu’ESET SysRescue Live entre en jeu.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-972879737\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p><strong><a href=\"https://www.eset.com/fr/support/sysrescue/\" target=\"_blank\" rel=\"noopener\">ESET SysRescue Live</a></strong> est un outil <strong>anti-malware</strong> qui fonctionne via un support amovible (CD, DVD ou clé USB) et qui peut être utilisé indépendamment du système d’exploitation installé sur votre ordinateur. Ce petit génie peut ainsi éliminer les menaces persistantes en accédant directement au disque dur et aux fichiers système. Compatible avec plusieurs versions de Windows, il est conçu pour analyser et éliminer les menaces à la demande.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"637\" height=\"477\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230911-kr2.webp\" alt=\"\" class=\"wp-image-153985\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230911-kr2.webp 637w, https://korben.info/app/uploads/2023/09/SCR-20230911-kr2-300x225.webp 300w\" sizes=\"(max-width: 637px) 100vw, 637px\" /></figure></div>\n\n\n<p>Pour utiliser ESET SysRescue Live, vous devez d’abord télécharger l’image ISO / IMG et la graver sur un CD/DVD ou créer une clé USB bootable. Une fois cela fait, insérez le support amovible et redémarrez votre ordinateur. Assurez-vous que votre ordinateur est configuré pour démarrer depuis le support amovible (vous devrez peut-être accéder aux paramètres du BIOS pour cela).</p>\n\n\n\n<p>Une fois ESET SysRescue Live lancé, vous serez accueilli par une interface utilisateur simple et conviviale. L’outil vous proposera de mettre à jour sa base de données de signatures de virus. Il est fortement recommandé de le faire pour assurer une détection optimale des menaces. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230911-kuy-1024x768.webp\" alt=\"\" class=\"wp-image-153987\" style=\"width:758px;height:569px\" width=\"758\" height=\"569\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230911-kuy-1024x768.webp 1024w, https://korben.info/app/uploads/2023/09/SCR-20230911-kuy-300x225.webp 300w, https://korben.info/app/uploads/2023/09/SCR-20230911-kuy-768x576.webp 768w, https://korben.info/app/uploads/2023/09/SCR-20230911-kuy.webp 1166w\" sizes=\"(max-width: 758px) 100vw, 758px\" /></figure></div>\n\n\n<p>Après la mise à jour, vous pouvez lancer une analyse de votre ordinateur. ESET SysRescue Live offre plusieurs options d’analyse, notamment une <strong>analyse rapide</strong>, une <strong>analyse intelligente</strong> et une <strong>analyse personnalisée</strong>. Les deux premières options analysent les zones les plus couramment infectées, tandis que l’option personnalisée vous permet de choisir les disques et dossiers spécifiques à analyser. Une fois l’analyse terminée, les menaces détectées seront affichées et vous pourrez les supprimer en toute sécurité.</p>\n\n\n\n<p>Il est important de noter qu’ESET SysRescue Live n’est pas conçu pour remplacer votre logiciel antivirus habituel. Il est plutôt destiné à être utilisé en complément, en particulier dans les situations où un malware persistant empêche le bon fonctionnement de votre système. Cet outil est idéal pour les situations où vous devez éradiquer un malware tenace qui résiste aux méthodes de suppression traditionnelles.</p>\n\n\n\n<p>Vous y trouverez également des utilitaires pratiques comme memtest, Midnight Commander ou Gparted pour ceux qui veulent partitionner leur disque ou augmenter la taille de leurs partitions existantes.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230911-kvx-1024x768.webp\" alt=\"\" class=\"wp-image-153986\" style=\"width:778px;height:584px\" width=\"778\" height=\"584\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230911-kvx-1024x768.webp 1024w, https://korben.info/app/uploads/2023/09/SCR-20230911-kvx-300x225.webp 300w, https://korben.info/app/uploads/2023/09/SCR-20230911-kvx-768x576.webp 768w, https://korben.info/app/uploads/2023/09/SCR-20230911-kvx.webp 1166w\" sizes=\"(max-width: 778px) 100vw, 778px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-325388679\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>En résumé, ESET SysRescue Live est un outil pratique et puissant pour nettoyer votre ordinateur des menaces persistantes qui refusent de partir ou pour effectuer des petites opérations de maintenance sur l’ordi.</p>\n",

Et vous pouvez aussi paramétrer vos tâches pour qu’elles vous soit proposées de manière récurrentes (toutes les semaines par exemple).</p>\n\n\n\n<p>Il est également possible d’associer des notes pour chaque tâche et d’y joindre des URLs (de la documentation par exemple) pour ouvrir ensuite ça d’un petit coup de raccourci clavier.</p>\n\n\n\n<p>Godspeed est utilisable via son API si vous souhaitez intégrer tout ça dans vos outils comme IFTTT / Zapier, vous pouvez exporter les data au format JSON et vous avez la possibilité de l’utiliser en mode clair ou sombre pour ne pas vous flinguer les yeux.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-928652045\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Et pour les puristes, il existe même au sein de Godspeed, un mode « hardcore » pour désactiver la souris et tout faire au clavier tel un pianiste sous amphétamine.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"915\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230911-jrz-1024x915.webp\" alt=\"\" class=\"wp-image-153981\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230911-jrz-1024x915.webp 1024w, https://korben.info/app/uploads/2023/09/SCR-20230911-jrz-300x268.webp 300w, https://korben.info/app/uploads/2023/09/SCR-20230911-jrz-768x686.webp 768w, https://korben.info/app/uploads/2023/09/SCR-20230911-jrz.webp 1113w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>En conclusion, je ne peux que vous recommander de tester <strong>Godspeed</strong> si vous êtes à la recherche d’une solution simple et efficace pour gérer votre temps et vos tâches.

Mais en y regardant de plus près, les tests effectués ont montré une <strong>diminution significative des performances</strong> des disques chiffrés par ce logiciel. C’est pas ouf. </p>\n\n\n\n<p>Alors que faire ?</p>\n\n\n\n<p>Et bien si vous êtes un utilisateur de Windows 11 Pro, la première chose à faire est de vérifier si BitLocker est activé, et s’il utilise un chiffrement logiciel (XTS-AES). Pour ce faire, ouvrez le menu Démarrer et entrez « <em>cmd</em>« .</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-772881960\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Ensuite, choisissez l’option « <em>Exécuter en tant qu’administrateur</em> » pour ouvrir une fenêtre d’invite de commandes avec les droits admin qui vont bien. Une fois dans l’invite de commandes, copiez et collez la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>manage-bde -status</code></pre>\n\n\n\n<p>Puis faites « Entrée ». Cette commande affichera alors le statut de tous vos volumes connectés. Enfin, pour savoir si le chiffrement BitLocker est activé ou non, recherchez la mention « <em>Protection Status</em>« . </p>\n\n\n\n<p>Si le chiffrement est activé, vérifiez alors la méthode de chiffrement utilisée. Si vous trouvez la mention « <em>XTS-AES</em>« , cela signifie que le chiffrement logiciel est utilisé et que par conséquent, Bitlocker a un impact négatif sur votre SSD.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" fetchpriority=\"high\" width=\"1024\" height=\"565\" src=\"https://korben.info/app/uploads/2023/10/3-1024x565.webp\" alt=\"\" class=\"wp-image-154629\" srcset=\"https://korben.info/app/uploads/2023/10/3-1024x565.webp 1024w, https://korben.info/app/uploads/2023/10/3-300x166.webp 300w, https://korben.info/app/uploads/2023/10/3-768x424.webp 768w, https://korben.info/app/uploads/2023/10/3-1536x848.webp 1536w, https://korben.info/app/uploads/2023/10/3.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Maintenant, plusieurs choix s’offrent à vous. Vous pouvez vous amuser à reformater votre PC et réinstaller Windows 11 Pro <a href=\"https://helgeklein.com/blog/how-to-enable-bitlocker-hardware-encryption-with-ssd/\" target=\"_blank\" rel=\"noopener\">en tenant compte de bien activer le chiffrement hardware</a> si votre ordinateur et votre SSD le supportent. C’est vraiment la meilleure des options même si cela implique d’effacer tout et de tout refaire au propre.</p>\n\n\n\n<p>Vous pouvez également désactiver BitLocker et ne plus rien chiffrer. C’est pas ouf niveau sécurité mais c’est un choix qui ne regarde que vous. Pour désactiver Bitlocker, ouvrez une nouvelle fois un terminal en mode admin et entrez la commande suivante en indiquant l’emplacement de votre disque (ici c’est « c: »)</p>\n\n\n\n<pre class=\"wp-block-code\"><code>manage-bde off C:</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"565\" src=\"https://korben.info/app/uploads/2023/10/1-1024x565.webp\" alt=\"\" class=\"wp-image-154630\" srcset=\"https://korben.info/app/uploads/2023/10/1-1024x565.webp 1024w, https://korben.info/app/uploads/2023/10/1-300x166.webp 300w, https://korben.info/app/uploads/2023/10/1-768x424.webp 768w, https://korben.info/app/uploads/2023/10/1-1536x848.webp 1536w, https://korben.info/app/uploads/2023/10/1.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Et si vous voulez quand même chiffrer sérieusement un disque dur, sans pour autant passer par Bitlocker, il y a toujours <a rel=\"noopener\" href=\"https://www.veracrypt.fr/en/Home.html\" target=\"_blank\">Veracrypt</a> qui peut vous aider notamment grâce à <a rel=\"noopener\" href=\"https://www.veracrypt.fr/en/System%20Encryption.html\" target=\"_blank\">sa fonctionnalité de chiffrement du système Windows</a>. Attention quand même, ce genre d’outils peut également impacter les performances de certains SSD, donc renseignez-vous bien avant de le mettre en place, car pas sûr que ça arrange la situation. Même chose pour les bons disques durs (HDD), qui peuvent aussi être impactés dans une moindre mesure.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-611658647\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Bon courage 🙂</p>\n\n\n\n<p><a href=\"https://www.ghacks.net/2023/10/20/report-bitlocker-slowing-down-ssds-on-windows-11-by-up-to-45/\" target=\"_blank\" rel=\"noopener\">Source</a></p>\n",

Plus besoin de vérifier manuellement les sites pour les mises à jour ! Imaginez être averti dès que votre site préféré publie un nouvel article, ou dès qu’une nouvelle version de votre logiciel favori est disponible. Grâce à web.Monitor, vous pouvez désormais le faire facilement.</p>\n\n\n\n<p>Ce petit logiciel libre et en ligne de commande est <strong>rapide et facile à utiliser</strong>, offrant une surveillance continue, une configuration flexible, un stockage persistant, une journalisation détaillée, des notifications, la visualisation des modifications, le filtrage des domaines, l’automatisation et la personnalisation. Cerise sur le gâteau, il prend en charge les notifications ce qui vous permettra ensuite d’envoyer des updates vers vos <strong>Telegram, Slack et Discord</strong> pour ne jamais manquer une alerte !</p>\n\n\n\n<p>Pour configurer web.Monitor, commencez par définir le chemin des binaires dans le fichier <code>web-monitor.ini</code>.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-289442564\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Pour ajouter une URL à la base de données, vous pouvez utiliser les commandes suivantes pour suivre une liste de sites ou un site seulement : </p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>python3 web.monitor.py --add-urls urls.txt</code>\npython3 web.monitor.py --add korben.info</code></pre>\n\n\n\n<p>Les notifications seront alors envoyées après le premier scan.</p>\n\n\n\n<p>Pour scanner toutes les URL d’un domaine racine, vous pouvez également utiliser :</p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>python3 web.monitor.py -df roots.txt --check -H 1</code>\npython3 web.monitor.py -D korben.info --check -H 1</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"738\" height=\"428\" src=\"https://korben.info/app/uploads/2023/09/SCR-20230911-cws.webp\" alt=\"\" class=\"wp-image-153977\" srcset=\"https://korben.info/app/uploads/2023/09/SCR-20230911-cws.webp 738w, https://korben.info/app/uploads/2023/09/SCR-20230911-cws-300x174.webp 300w\" sizes=\"(max-width: 738px) 100vw, 738px\" /></figure></div>\n\n\n<p>Le paramètre -df est utilisé pour analyser toutes les URL d’un domaine racine. Par exemple, si les URL admin.site.com et admin.site2.com se trouvent dans la base de données et que le fichier roots.txt contient uniquement *.site.com, l’analyse portera sur *.site.com. </p>\n\n\n\n<p>L’indicateur -D , quand à lui, analyse uniquement les URL du site indiqué dans la commande. Le paramètre -H est utilisé pour spécifier que le domaine sera scanné toutes les 1 heures, et bien sûr, vous pouvez personnaliser cela. La recommandation c’est de scanner toutes les 12 ou 24 heures afin de ne pas vous faire blacklister ou Ddos les sites.</p>\n\n\n\n<p>Et si vous voulez afficher les changements d’un domaine spécifique, voici la commande qu’il vous faut :</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1143430249\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p><code>python3 web.monitor.py -D korben.info --show-changes</code></p>\n\n\n\n<p>Voilà !

En effet, les chercheurs de <strong>Team82</strong> ont découvert un bug intéressant chez <strong><a href=\"https://korben.info/quel-nas-synology-choisir.html\">Synology</a></strong>, qui prouve que parfois <a href=\"https://claroty.com/team82/research/synology-nas-dsm-account-takeover-when-random-is-not-secure\" target=\"_blank\" rel=\"noopener\">une solution simple peut créer un problème complexe</a>.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-478950454\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Synology est un nom populaire dans le monde des systèmes de stockage réseau (NAS). Leur système d’exploitation, <strong>DiskStation Manager (DSM)</strong>, est conçu pour vous aider à gérer et partager vos fichiers facilement et de manière centralisée. Mais, malheureusement, ils ont utilisé une approche trop simpliste pour générer le mot de passe administrateur du NAS lors de sa création. Et cela a ouvert une voie exploitable par les attaquants.</p>\n\n\n\n<p>Cette vulnérabilité, référencée sous le code <a href=\"https://claroty.com/team82/disclosure-dashboard/cve-2023-2729\" target=\"_blank\" rel=\"noopener\">CVE-2023-2729</a>, provient de l’utilisation de la méthode <code>Math.random()</code> pour générer le mot de passe administrateur. Cette méthode n’est pas cryptographiquement sécurisée, et un attaquant pourrait récupérer suffisamment d’informations afin de reconstruire le mot de passe admin. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"512\" src=\"https://korben.info/app/uploads/2023/10/SCR-20231019-gnam.webp\" alt=\"\" class=\"wp-image-154586\" style=\"aspect-ratio:1.953125;width:564px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/10/SCR-20231019-gnam.webp 1000w, https://korben.info/app/uploads/2023/10/SCR-20231019-gnam-300x154.webp 300w, https://korben.info/app/uploads/2023/10/SCR-20231019-gnam-768x393.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Toutefois, rassurez-vous, il faut que pas mal de conditions soient réunies pour que cela se produise en vrai. Mais on ne sait jamais ^^.</p>\n\n\n\n<p>Alors, comment ça se passe en réalité ? </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-343726837\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Et bien, l’équipe de recherche a découvert qu’en faisant fuiter la sortie de quelques valeurs générées par <code>Math.random()</code>, il était possible de reconstruire la valeur de la seed utilisée pour le générateur de nombres pseudo-aléatoires (PRNG). En connaissant cette seed, un attaquant pourrait alors prédire les valeurs futures et générer le mot de passe administrateur permettant alors de prendre le contrôle du compte admin.</p>\n\n\n\n<p>Bien sûr, ce n’est pas si simple : pour exécuter l’attaque, il faut d’abord trouver un moyen de récupérer certaines valeurs <code>Math.random()</code>. Mais les chercheurs ont découvert que certains GUID générés lors de la première installation utilisaient également <code>Math.random()</code>, et que ces GUID pouvaient être utilisés pour reconstruire la graine PRNG.</p>\n\n\n\n<p>Cependant, même si un attaquant réussissait à récupérer ces informations, cela ne suffirait pas en soi. Par défaut, le compte administrateur intégré est désactivé, et la plupart des utilisateurs ne l’activeraient pas (Et ils ont raison !). </p>\n\n\n\n<p>Cette vulnérabilité a été découverte en préparant le concours Pwn2Own et les gens qui ont travaillé là dessus s’accordent pour dire que cette faille serait presque impossible à exploiter dans une situation réelle. Toutefois, ils ont quand même décidé de partager leur découverte pour souligner l’importance d’utiliser des générateurs de nombres aléatoires cryptographiquement sécurisés lors de la création de mots de passe.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" width=\"807\" height=\"750\" src=\"https://korben.info/app/uploads/2023/10/SCR-20231019-gnmn.webp\" alt=\"\" class=\"wp-image-154587\" style=\"aspect-ratio:1.076;width:543px;height:auto\" srcset=\"https://korben.info/app/uploads/2023/10/SCR-20231019-gnmn.webp 807w, https://korben.info/app/uploads/2023/10/SCR-20231019-gnmn-300x279.webp 300w, https://korben.info/app/uploads/2023/10/SCR-20231019-gnmn-768x714.webp 768w\" sizes=\"(max-width: 807px) 100vw, 807px\" /></figure></div>\n\n\n<p>Bref, si vous êtes développeurs, n’utilisez pas <code>Math.random()</code> pour générer des nombres aléatoires quand il s’agit de faire de la sécurité. À la place, il est recommandé d’utiliser l’API Web Crypto et, plus précisément, la méthode <a href=\"https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues\" target=\"_blank\" rel=\"noopener\"><code>window.crypto.getRandomValues()</code></a>.</p>\n\n\n\n<p><a href=\"https://korben.info/quel-nas-synology-choisir.html\">Synology a évidemment été informé de la vulnérabilité</a>, et ils ont rapidement publié un correctif pour les appareils concernés. Les utilisateurs de DSM 7.2 sont donc invités à mettre à niveau leur système vers la version 7.2-64561 ou ultérieure.</p>\n",

Et bien aujourd’hui nous allons voir comment les choses ont évoluées ces derniers mois et comment le logiciel s’est amélioré avec une toute nouvelle version 7.5 qui arrive sous peu ! Avec quelques options que vous pourriez trouver intéressantes 😉</p>\n\n\n\n<p>Mais tout d’abord on va commencer par resituer un peu ce que propose cet outil open source (le code est sur Github). En gros il s’agit d’une suite bureautique complète (digne de Google Workspace, Zoho ou Microsoft 365) … sauf qu’elle peut s’autohéberger ! Vous pouvez donc disposer d’une suite personnelle, que vous allez gérer de A à Z. Finies les données qui circulent chez des GAFAM ou autres tiers de confiance, ce qui est plutôt cool pour les entreprises par exemple.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"750\" height=\"428\" src=\"https://kbn.im/onlyofficedocspace23\" alt=\"Tableur ONLYOFFICE\"/></figure></div>\n\n\n<p>La suite propose tout ce dont vous pourriez avoir besoin, seul ou en équipe (puisqu’il est possible de collaborer). Cela va du fichier traitement de texte classique, au tableur en passant par la réalisation de formulaires ou de présentations ou encore la création d’ebooks. Et ça, c’est uniquement pour la version Docs, donc celle de base.</p>\n\n\n\n<p>Avec <a href=\"https://www.onlyoffice.com/fr/docspace.aspx\" target=\"_blank\" rel=\"noopener\">Docspace</a> vous pourrez affiner les permissions de partage (visualisation seule, revue du fichier, commentaires …), créer des sessions de groupe (avec chat et vidéocall), inviter des utilisateurs et bientôt des sessions privées. Pour les entreprises il y a l’option Workspace qui permet non seulement de gérer vos documents, mais aussi de proposer des adresses mails corporate, un CRM, de créer des calendriers partagés et faire de la gestion de projets. Bref vous le voyez c’est très complet et ça explique les 10+ millions d’utilisateurs (dont Fujitsu, Deloitte, Seafile …) !</p>\n\n\n\n<h2 class=\"wp-block-heading\">ONLYOFFICE nouvelle version</h2>\n\n\n\n<p>Parmi les nouveautés il y a l’ajout d’un éditeur pour les fichiers PDF (très attendu j’imagine vu la popularité du format surtout dans les entreprises). Pour l’instant il n’est pas encore possible d’éditer un PDF à plusieurs, mais cela devrait arriver bientôt.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"750\" height=\"428\" src=\"https://korben.info/app/uploads/2023/10/editeur-pdf.jpg\" alt=\"Editeur PDF\" class=\"wp-image-154472\" srcset=\"https://korben.info/app/uploads/2023/10/editeur-pdf.jpg 750w, https://korben.info/app/uploads/2023/10/editeur-pdf-300x171.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></figure></div>\n\n\n<p>L’équipe derrière le projet a aussi continué à prendre en compte les retours d’utilisateurs pour mettre en place les améliorations les plus demandées. Comme la césure automatique, la mémorisation de paramètres lors de l’ouverture de fichiers CSV … et une fonctionnalité d’accessibilité (encore en beta) que je trouve assez sympa et qui reprend, sous forme vocale, les actions réalisées dans les différents éditeurs. Sans oublier les habituelles mises à jour d’amélioration des outils (effets de transitions dans l’outil de présentation, tableaux croisés dynamiques dans le tableur …), de l’interface, quelques bugs, etc. </p>\n\n\n\n<p>En plus vous allez pouvoir intégrer la suite avec des outils que vous utilisez peut-être déjà grâce aux connecteurs et plugins mis à disposition. WordPress, Odoo, Nextcloud, Confluence, ChatGPT, YouTube, Moodle, Box (depuis quelques jours seulement) … au fil des mois <a href=\"https://www.onlyoffice.com/all-connectors.aspx\" data-type=\"link\" data-id=\"https://www.onlyoffice.com/all-connectors.aspx\" target=\"_blank\" rel=\"noreferrer noopener\">il commence a y en avoir pas mal</a>. Du côté des devs il y a de quoi faire avec une API, le support du protocole Web Application Open Platform Interface Protocol (WOPI), etc. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"750\" height=\"428\" src=\"https://korben.info/app/uploads/2023/10/document-onlyoffice.jpg\" alt=\"Hyphenation\" class=\"wp-image-154474\" srcset=\"https://korben.info/app/uploads/2023/10/document-onlyoffice.jpg 750w, https://korben.info/app/uploads/2023/10/document-onlyoffice-300x171.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></figure></div>\n\n\n<p>Et côté sécurité on peut noter que les données sont chiffrées via les algo AES-256 et TLS, un standard que l’on retrouve dans pas mal d’autres logiciels de sécu (comme les gestionnaires de mots de passe par exemple). L’outil est aussi, bien entendu, respectueux du RGPD (ou HIPAA si vous habitez aux US) et supporte la conversion d’un tas d’extensions (xls, ods, doc, html, epub, xml, ppt … plusieurs dizaines).</p>\n\n\n\n<p>Ah oui, et juste pour le mentionner, c’est compatible avec tous les OS les plus utilisés. La <a href=\"https://www.onlyoffice.com/fr/download-docs.aspx\" target=\"_blank\" rel=\"noopener\">version auto-hébergée d’ONLYOFFICE Docs</a> est disponible pour Windows, macOS et Linux. Vous pouvez d’ailleurs <a href=\"https://www.onlyoffice.com/fr/download-desktop.aspx#desktop\" target=\"_blank\" rel=\"noopener\">télécharger gratuitement les applications en mode desktop</a> (ONLYOFFICE Desktop Editors). Toutes les options ne sont pas dispo, mais vous pourrez travailler en local avec une version à jour.</p>\n\n\n\n<p>Si vous voulez voir concrètement comment ça fonctionne, je vous remets la vidéo que j’ai réalisée l’an dernier sur le sujet. Tout n’est pas 100% à jour, mais dans les très grandes lignes ça reste d’actualité.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"OnlyOffice - La suite bureautique à auto-héberger\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/ZgTVFKuxVOg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div><figcaption class=\"wp-element-caption\"><em>(abonne-toi, fais péter le pouce bleu, active la cloche et commente pour le référencement … loool)</em></figcaption></figure>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://www.onlyoffice.com/fr/docspace-registration.aspx\" data-type=\"link\" data-id=\"https://www.onlyoffice.com/fr/docspace-registration.aspx\" target=\"_blank\" rel=\"noreferrer noopener\">Découvrir ONLYOFFICE</a></h2>\n",

Une véritable tour de Babel moderne qui vous permet de transcrire des réunions en anglais, espagnol, ou même en swahili</p>\n\n\n\n<p>Et le meilleur la dedans, c’est qu’elle garantit la confidentialité de vos données, puisque tout est traité localement.</p>\n\n\n\n<p>Le modèle Whisper d’OpenAI a bien sûr quelques petits défauts, comme l’absence de ponctuation ou la division du texte en paragraphes mais ne vous inquiétez pas ! Grâce à <strong>ChatGPT</strong>, vous pouvez corriger tous ces éventuels petits problèmes à l’aide des prompts suivant (GPT-3.5) :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>Remove newlines and divide the text into paragraphs. Don't change the text otherwise: VOTRE TEXTE\nFix the missing punctation. Don't change the text otherwise: VOTRE TEXTE</code></pre>\n\n\n\n<p>Une fois que vous avez votre transcription, Aiko peut alors l’exporter dans différents formats textuels.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"640\" src=\"https://korben.info/app/uploads/2023/09/screenshot1.2ecc32f3-1024x640.webp\" alt=\"\" class=\"wp-image-153960\" srcset=\"https://korben.info/app/uploads/2023/09/screenshot1.2ecc32f3-1024x640.webp 1024w, https://korben.info/app/uploads/2023/09/screenshot1.2ecc32f3-300x188.webp 300w, https://korben.info/app/uploads/2023/09/screenshot1.2ecc32f3-768x480.webp 768w, https://korben.info/app/uploads/2023/09/screenshot1.2ecc32f3-1536x960.webp 1536w, https://korben.info/app/uploads/2023/09/screenshot1.2ecc32f3-2048x1280.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-97404650\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Maintenant, parlons des formats audio et vidéo pris en charge par Aiko. Il supporte le .m4a, .wav, .mp3, .mp4, .mov à l’exception du format .ogg. </p>\n\n\n\n<p>Et si vous avez des mémos vocaux à transcrire, Aiko en est également capable ! La vitesse de transcription dépendra de votre ordinateur et de la mémoire disponible et, bien que l’application soit volumineuse en raison de la prise en charge de 100 langues, cela en vaut la peine pour la qualité de transcription offerte.</p>\n\n\n\n<p>Et qu’en est-il de la transcription en temps réel ? Et bien, c’est prévu, mais d’autres demandes sont prioritaires pour le moment d’après le dev, donc il faudra encore un peu patienter. Du coup pour transcrire une réunion Zoom ou une note vocale Telegram, vous devrez enregistrer la réunion, puis utiliser Aiko, ou convertir les notes vocales Telegram au format AAC. </p>\n\n\n\n<p>Et pour les sous-titres (SRT) ? Cliquez sur le bouton « partager » et choisissez « SRT ». </p>\n\n\n\n<p>Si vous voulez transcrire une vidéo YouTube vous devrez récupérer l’audio avec un service comme <a href=\"https://dirpy.com/from/youtube\" target=\"_blank\" rel=\"noopener\">Dirpy</a>, puis ouvrez le fichier dans Aiko pour lui faire faire la transcription.</p>\n\n\n\n<p>Notez que l’application prend en charge uniquement la traduction en anglais pour le moment, mais qui sait ce que l’avenir nous réserve ?</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-447755243\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Aiko est gratuite et sans publicité. <a href=\"https://sindresorhus.com/aiko\" target=\"_blank\" rel=\"noopener\">Vous pouvez la télécharger ici</a> ! </p>\n\n\n\n<p>J’espère que cette présentation d’Aiko vous a plu et que vous êtes aussi enthousiastes que moi à l’idée de l’essayer.</p>\n",

Si ce n’est pas le cas, laissez-moi vous expliquer tout ça. OSCP c’est pour <strong>Offensive Security Certified Professional</strong>, donc comme le nom l’indique, c’est plutôt très axé sur la sécurité. Cette certification a d’ailleurs vu le jour sous l’égide de l’OffSec, une société reconnue dans le monde de la cybersécurité. Et que vous connaissez peut-être déjà puisque c’est à elle que l’on doit l’une des meilleures distrib Linux du mooonde, j’ai nommé Kali. Bref c’est du lourd.</p>\n\n\n\n<p>Autant le dire tout de suite, il s’agit d’<strong>une certif de haut niveau</strong>, unanimement reconnue et qui vous situera de suite dans la crème des pentesteurs et des hackers éthiques mondiaux. En passant à l’attaque en mode commando Red Team, vous ferez partie d’une communauté soudée avec qui partager vos expériences. Rien que ça, c’est déjà 2 belles raisons de la passer.</p>\n\n\n\n<p>Vu le niveau de la certification, vous vous doutez bien que ce n’est pas de tout repos et vous allez en baver. En effet, il vous faudra un investissement personnel de 2h par jour (au minimum !) pour pirater tous les labs mis à disposition. Mais ne vous inquiétez pas, le bootcamp proposé par <a href=\"https://www.ambient-it.net/formation/oscp/\" target=\"_blank\" rel=\"noopener\">Ambient IT</a> vous motivera pendant 10 semaines chaque lundi matin en Classe Virtuelle.</p>\n\n\n\n<p>Mais attention, cœur sensible s’abstenir, il faut certains prérequis en administration Linux/Windows, en réseau (TCP/IP) et des bases en Python/Bash. Votre ordinateur devra avoir un minimum de puissance (mais rien de fou) et avoir Kali Linux installé.</p>\n\n\n\n<p><strong>La prochaine session</strong> démarre le 15 janvier, dépêchez-vous si vous ne voulez pas la louper. D’autant que pour les salariés du Syntec (secteur informatique dont bon nombre de mes lecteurs font partie), vous bénéficiez d’un bonus sur votre CPF de 4000€ grâce à l’Atlas (limité dans le temps).Et si vous êtes chef d’entreprise artisanale, vous pouvez faire appel au Fonds d’Assurance Formation (FAFCEA). À voir aussi du côté de Pôle Emploi si vous êtes au chômage, ils peuvent vous aider à la financer. Voir <a href=\"https://www.moncompteformation.gouv.fr/espace-prive/html/#/formation/recherche/81227101300045_oscp/81227101300045_oscp?contexteFormation=ACTIVITE_PROFESSIONNELLE\" target=\"_blank\" rel=\"noopener\">la fiche sur Mon Compte Formation</a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"560\" src=\"https://kbn.im/ambientitoscp\" alt=\"\"/></figure></div>\n\n\n<p>Qu’est-ce que vous allez apprendre concrètement ?</p>\n\n\n\n<ul>\n<li>les principales vulnérabilités en milieu professionnel</li>\n\n\n\n<li>les techniques d’intrusion des systèmes</li>\n\n\n\n<li>développer vos compétences de pentesting</li>\n\n\n\n<li>bind et reverse shells</li>\n\n\n\n<li>effectuer des reconnaissances : cartographie, découverte passive et active, scan SSL/TLS…</li>\n\n\n\n<li>Attaques Web (injections SQL, XSS…)</li>\n\n\n\n<li>ActiveDirectory</li>\n\n\n\n<li>et bien évidemment écrire des beaux rapports d’audit</li>\n\n\n\n<li>…etc</li>\n</ul>\n\n\n\n<p>Donnée par un expert de la sécurité web (<a href=\"https://www.offsec.com/partner-locator/\" target=\"_blank\" rel=\"noopener\">certifié OSCP</a> et OSWE), la formation se focalise pas mal sur le côté pratique (comme la plupart du temps chez <a href=\"https://www.ambient-it.net/formation/oscp/\" target=\"_blank\" rel=\"noopener\">Ambient IT</a>). Ne vous attendez donc pas à une suite de sessions théoriques (même si vous aurez aussi un livre de 850 pages en accompagnement), ici <strong>vous serez vraiment mis au contact des conditions réelles</strong>. Ce qui vous amènera à maîtriser différents outils et techniques de manières concrètes. Et une fois que la formation est terminée ? Ce n’est pas fini puisqu’il vous faudra passer l’examen pour obtenir la certification.</p>\n\n\n\n<p>Et ce dernier n’est pas de tout repos non plus puisqu’il se tient sur une durée de… 24h. Une journée à tenter d’attaquer des systèmes et trouver des moyens de résoudre les failles. Sans même parler de l’audit qui suit. Il faut être très solide, mais c’est la 3e raison de passer la certification. Parce que rien ne remplacera l’expérience de fou que vous allez vivre.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"480\" height=\"270\" src=\"https://media.giphy.com/media/M960XBOtpI9nozI13V/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>S’il faut trouver un 4e point, c’est clairement<strong> le nombre d’opportunités qui s’ouvriront à vous</strong> par la suite. Au vu de tout ce que je viens de vous raconter, vous vous doutez bien que quelqu’un qui termine l’examen avec succès sera un profil TRÈS demandé. Et avec un salaire en conséquence (plus de 10k$/mois aux USA, en France en tant qu’indépendant vous pouvez espérer entre 75k€ et 160k€ de facturation à l’année).</p>\n\n\n\n<p>Enfin, dernière raison, c’est d’autant plus important que <strong>les dépenses en cybersécurité ne font qu’augmenter</strong> ces dernières années (aussi bien les gouvernements que les grosses entreprises gérant des données sensibles). Notamment à cause du climat mondial toujours plus tendu : guerre en Ukraine, augmentation continue des attaques informatiques entre nations, etc. Un joli +12% d’investissement prévu rien que cette année dans le monde, donc il y a de l’argent à dépenser dans le domaine (et on ne prévoit pas de ralentissement pour les prochaines années).</p>\n\n\n\n<p>Alors prêt à faire partie de l’élite mondiale en termes de sécurité informatique ?</p>\n\n\n\n<p>Si c’est le cas, rendez-vous sur <a href=\"https://www.ambient-it.net/formation/oscp/\" target=\"_blank\" rel=\"noopener\">Ambient IT</a>.</p>\n",

Vous pouvez également ajouter des <strong>signets</strong> pour vos films et épisodes préférés, et passer facilement d’une saison à l’autre ou d’un épisode au suivant, sans avoir à chercher manuellement. </p>\n\n\n\n<p>Comme mentionné précédemment, Movie-web est <strong>sans publicités</strong>. C’est un vrai bonheur de pouvoir regarder ses films et séries sans être interrompu par des annonces et des pop-ups intempestives. De plus, comme je le disais, <a href=\"https://github.com/movie-web/movie-web/blob/dev/SELFHOSTING.md\" target=\"_blank\" rel=\"noopener\">vous pouvez <strong>héberger vous-mêmes l’application</strong></a> (il vous faudra un compte Cloudflare), ce qui donne un contrôle total sur l’expérience de visionnage.</p>\n\n\n\n<p>Movie Web n’est donc rien de plus qu’un moteur de recherche capable de trouver le film de vos rêves, principalement en VO, sur la toile. Quelle bonne idée surtout que c’est totalement sous licence libre !</p>\n\n\n\n<p>Et si vous voulez une démo du service, je crois qu’il y en a une <a href=\"https://github.com/movie-web/movie-web/tree/dev\" target=\"_blank\" rel=\"noopener\">sur la page du projet Github</a>. </p>\n\n\n\n<p>Je vous laisse vérifier.</p>\n",

Cet été c’était la grande pause et c’était vraiment cool, car je ne me suis pas ennuyé. J’ai même creusé une mare naturelle avec des grenouilles qui se sont rapidement installées. Mare qui est encore un peu vide vu le manque de flotte en ce moment.</p>\n\n\n\n<p> J’ai également passé 2 semaines en Bretagne en août, esquivant la canicule puis en septembre, j’ai décidé de passer à la semaine de 3 jours, car, vous le savez, la vraie richesse, c’est pas le pognon, mais le temps libre. En gros, lundi, mardi et mercredi, je bosse à fond, je rush, <a href=\"http://twitch.tv/korbenfr\" target=\"_blank\" rel=\"noopener\">je streame</a>, je fais mes conf call, je tourne <a href=\"http://patreon.com/korben\" target=\"_blank\" rel=\"noopener\">mes vidéos</a>, j’écris mes articles et j’essaye de tout torcher asap.</p>\n\n\n\n<p>Et le mercredi soir, je suis « officiellement » en week-end. Alors je sais, ça fait rêver, mais la réalité, c’est que c’est plutôt un semi-weekend. C’est-à-dire que je bosse quand même un peu durant ces jours-là, car j’ai évidemment des trucs que je n’ai pas eu le temps de finir, mais je le fais sans pression. Je réponds plus au téléphone, je suis moins sur mes emails, ce qui me laisse plus de temps pour avancer dans le monde réel, pour réfléchir et expérimenter des trucs que je pourrais ensuite partager avec vous, et puis évidemment me faire plaisir, à savoir écrire des articles sur mon site, jouer à Starfield ou mater la nouvelle série OnePiece sur Netflix.</p>\n\n\n\n<p>La réalité, c’est que c’est plus un combat entre mon Moi qui veut du temps libre et qui se dit « <em>Et si on se lançait dans un nouveau Side-project n° 15456 ?</em> » et mon Moi qui se dit « <em>Oui, mais t’as pas le temps de t’amuser, y’a encore ça à faire, puis ça, puis ça, et la semaine prochaine, y’a ça, encore ça…</em>« .</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-467211617\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Bref, je tente et on verra si ce luxe tiendra dans la durée.</p>\n\n\n\n<p>Allez, passez un bon mois d’octobre et on se capte sur mes réseaux 🙂</p>\n",

"title": "Découverte du AK1PLUS – Le Mini PC Intel Alder Lake-N95 de NiPoGi",
|
||
"description": "Mon expérience d'achat d'un Mini PC AK1PLUS de NiPoGi pour déporter une partie de son streaming et effectuer des tests. Il apprécie le prix réduit de 229 euros après une réduction sur Amazon, comparé à 439 euros initialement. Le PC, doté d'un processeur Alder Lake-N95, 16 Go de DDR4 et un SSD M.2 NVMe de 1 TB, répond à ses besoins basiques malgré une réputation modeste du processeur chez Intel. Il apprécie la possibilité de dual boot entre Windows et Linux, et la facilité d'extension de l'espace disque grâce à un socle amovible pour un SSD supplémentaire. La connectivité, avec plusieurs ports USB, HDMI, Ethernet, est également un plus. Il a noté un inconvénient avec le port USB bootable uniquement à l'arrière du PC. L'aspect compact et silencieux du Mini PC, avec une installation aisée de l'OS et un bon support pour Linux, lui convient bien pour des tâches basiques comme la bureautique et le streaming, bien qu'il ne soit pas adapté pour le gaming ou la 3D.",

J’ai juste dû passer sur un noyau Linux 6.5.6 pour avoir un bon support du processeur graphique d’Intel qui est quand même récent et donc avoir ainsi une résolution d’écran correcte.</p>\n\n\n\n<p>Par contre, attention, si vous vous lancez là-dedans, sachez que le seul port USB réellement bootable est celui qui se trouve à l’arrière.

C’est donc un mini PC silencieux et discret, avec un CPU récent et performant pour peu que vous vous contentiez de faire de la bureautique / internet / mater des films avec. </p>\n\n\n\n<p>Ça conviendra bien à ceux qui ont un petit budget, qui veulent un minimum d’encombrement et surtout du silence 🙂 et comme ça supporte très bien Linux, y’a de quoi faire aussi d’autres trucs cool.</p>\n\n\n\n<p>Par contre, encore une fois, oubliez les usages qui demandent du GPU. C’est loin d’être un PC avec lequel on peut jouer à des jeux récents ou faire de la 3D.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Mini PC NiPoGi-AK1 Plus, Intel Alder Lake N95, 8GB DDR4 256GB SSD, Windows 11 Pro\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/Q5utKG3cWLo?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Notez que <strong><a href=\"https://amzn.to/3F9GWcy\" target=\"_blank\" rel=\"noopener\">d’autres modèles sont également dispo chez NiPoGi</a></strong> avec moins d’espace disque, moins de RAM, donc moins chers (et également de chouettes bons de réduction).</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-80911138\" data-NKSYD1CP-trackid=\"124510\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_5' style='display:none;' class=\"Content_5\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos5' style='display:none;' class=\"Mobile_Pos5\"></div></div><p>À voir maintenant ce que ça donnera sur le long terme.</p>\n",

C’est ce que nous propose <a rel=\"noopener\" href=\"https://www.trepang2game.com/\" target=\"_blank\">Trepang2</a>, un FPS à la John Wick avec une pointe d’horreur, autant vous dire que c’est sanglant. 😀</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Trepang2 | Launch Trailer\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/pIhx-Lgqi_E?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Contrairement à ce que son titre pourrait laisser penser, <a href=\"https://www.trepang2game.com/\" target=\"_blank\" rel=\"noopener\">Trepang2</a> n’est pas une suite, c’est d’ailleurs le premier jeu <a href=\"https://www.trepang2game.com/\" target=\"_blank\" rel=\"noopener\">Trepang Studios</a>, toute nouvelle équipe de seulement 4 personnes ! Ils ont fait un boulot de dingue, franchement c’est super maîtrisé, à la hauteur de pas mal de titre créés par de groooosses équipes. 🙂 Pas étonnant que Team17 décide de publier le jeu.</p>\n\n\n\n<p>Le gameplay est super bien foutu, simple et accessible à appréhender mais bien nerveux, et permet d’être assez créatif. En plus de tirer avec ses flingues (on peut porter jusqu’à 2 armes à la fois, à nous de choisir celles qui nous semblent les plus adaptées), de balancer des grenades, de faire des glissades ou de se servir d’un ennemi comme bouclier, on peut se rendre invisible mais aussi activer un mode « bullet time » qui s’avèrera bien pratique !</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/10/Trepang2-2.webp\" alt=\"\" class=\"wp-image-154350\" srcset=\"https://korben.info/app/uploads/2023/10/Trepang2-2.webp 1000w, https://korben.info/app/uploads/2023/10/Trepang2-2-300x169.webp 300w, https://korben.info/app/uploads/2023/10/Trepang2-2-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Graphiquement c’est super propre, fluide, mais surtout y a une excellente ambiance qui s’installe. Y a un côté John Wick / Matrix, mélangé à du surnaturel et parfois même de l’horreur… Je vous ai dit que c’était sanglant ? 😀 Je ne sais pas si vous vous souvenez de <a href=\"https://fr.wikipedia.org/wiki/FEAR_(jeu_vid%C3%A9o)\" target=\"_blank\" rel=\"noopener\">F.E.A.R.</a>, mais c’est assez similaire : faut pas avoir peur du noir ! Le scénario est assez basique mais on se laisse porter. Efficace.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-943241751\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Des infos complémentaires sont dispo en retrouvant des logs via ordinateurs, téléphones, parchemins (?!) sur lesquels les personnages ont laissé des notes. On peut aussi trouver des améliorations d’armes, c’est sympa mais les niveaux n’invitent pas forcément à l’exploration, perso je pense être passé à côté de pas mal de trucs. Il va falloir fouiller pour obtenir le 100% !</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/10/Trepang2-4.webp\" alt=\"\" class=\"wp-image-154351\" srcset=\"https://korben.info/app/uploads/2023/10/Trepang2-4.webp 1000w, https://korben.info/app/uploads/2023/10/Trepang2-4-300x169.webp 300w, https://korben.info/app/uploads/2023/10/Trepang2-4-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>L’aventure est structurée en missions, entre chaque mission on revient à la base pour personnaliser un peu son personnage / ses armes, et choisir son prochain objectif : en effet certaines missions sont facultatives, à nous de choisir ce qu’on veut faire ou pas. Il est aussi possible de rejouer les niveaux déjà terminés, en changeant la difficulté par exemple. Enfin, il y a un mode « survie » avec des vagues d’ennemis de plus en plus nombreux et puissants, bref, de quoi allonger la durée de vie. 🙂</p>\n\n\n\n<p>L’histoire principale se boucle une première fois en 4-5h, et je pense qu’on peut largement doubler le temps de jeu avec ce contenu supplémentaire. C’est une expérience assez concise mais bien construite, et sur laquelle on peut revenir si on veut + de challenge : en mode <em>normal</em>, perso, je suis mort plus d’une fois, et ce n’est que le deuxième mode de difficulté sur… Six ! Le mode <em>rage</em> risque de vous faire <em>ragequit</em>. 😀</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/10/Trepang2-3.webp\" alt=\"\" class=\"wp-image-154349\" srcset=\"https://korben.info/app/uploads/2023/10/Trepang2-3.webp 1000w, https://korben.info/app/uploads/2023/10/Trepang2-3-300x169.webp 300w, https://korben.info/app/uploads/2023/10/Trepang2-3-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>En conclusion, c’est un excellent jeu de tir « défouloir », super fun, avec quelques moments bien flippants, et une bonne liberté dans notre manière d’appréhender les différentes situations périlleuses dans lesquels les développeurs adorent nous coincer. Bien sûr, faut aimer le genre, mais si c’est votre cas je pense qu’on peut lui accorder un <strong>💥💥💥💥/5</strong></p>\n\n\n\n<p>Il y a une démo de disponible si vous voulez tester. 😉</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">Acheter <a href=\"https://www.trepang2game.com/\" target=\"_blank\" rel=\"noopener\">Trepang2</a> sur <a href=\"https://store.steampowered.com/app/1164940/Trepang2/\" target=\"_blank\" rel=\"noopener\">Steam</a>, <a href=\"https://www.gog.com/en/game/trepang2\" target=\"_blank\" rel=\"noopener\">GoG</a>, <a href=\"https://www.xbox.com/en-US/games/store/trepang2/9NCDMPCPDTQF/0010\" target=\"_blank\" rel=\"noopener\">XBox</a> ou <a href=\"https://store.playstation.com/en-us/concept/10007968\" target=\"_blank\" rel=\"noopener\">Playstation</a></h2>\n",

Si vous travaillez sur un projet important, mais votre esprit est distrait par le bruit environnant, voici un excellent moyen de vous recentrer rapidement, sans pour autant quitter votre bureau de rage.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1910572026\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Opal est un <strong>lecteur de son d’ambiance relaxant</strong> conçu pour vous aider à rester concentré. Il dispose de <strong>plus de 30 pistes sonores apaisantes</strong>, allant du fond sonore de l’open space au bruit de la pluie, en passant par la forêt ou le café voire des sons plus imaginaires comme un château hanté ou une grotte mystérieuse. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/Opal.webp\" alt=\"\" class=\"wp-image-153264\" width=\"584\" height=\"420\" srcset=\"https://korben.info/app/uploads/2023/06/Opal.webp 1000w, https://korben.info/app/uploads/2023/06/Opal-300x216.webp 300w, https://korben.info/app/uploads/2023/06/Opal-768x554.webp 768w\" sizes=\"(max-width: 584px) 100vw, 584px\" /></figure></div>\n\n\n<p>Ce qui rend Opal particulièrement intéressant, c’est sa capacité à <strong>combiner des sons à différents volumes</strong>. Ainsi, vous pouvez créer votre propre mélange sonore afin que ça corresponde à votre humeur ou à votre environnement de travail. Si comme moi, vous avez toujours rêvé de travailler au milieu d’une forêt enchantée avec une légère pluie tombant sur les feuilles, pas de problème, Opal vous permettra de créer cette atmosphère en un clin d’œil.</p>\n\n\n\n<p>En plus de cela, Opal propose un <strong>minuteur </strong> pour ceux qui aiment programmer des sessions de concentration. Vous réglez le minuteur, et Opal s’arrêtera automatiquement une fois le temps écoulé. Comme ça, plus besoin de surveiller l’heure sur l’ordi !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/opal_timer.webp\" alt=\"\" class=\"wp-image-153265\" width=\"600\" height=\"470\" srcset=\"https://korben.info/app/uploads/2023/06/opal_timer.webp 957w, https://korben.info/app/uploads/2023/06/opal_timer-300x235.webp 300w, https://korben.info/app/uploads/2023/06/opal_timer-768x602.webp 768w\" sizes=\"(max-width: 600px) 100vw, 600px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/opal_settings.webp\" alt=\"\" class=\"wp-image-153266\" width=\"597\" height=\"468\" srcset=\"https://korben.info/app/uploads/2023/06/opal_settings.webp 957w, https://korben.info/app/uploads/2023/06/opal_settings-300x235.webp 300w, https://korben.info/app/uploads/2023/06/opal_settings-768x602.webp 768w\" sizes=\"(max-width: 597px) 100vw, 597px\" /></figure></div>\n\n\n<p><strong>Opal est open-source</strong> et est dispo pour Linux et Windows.

Ou peut-être avez-vous tout simplement envie de créer une vidéo amusante pour faire marrer vos potes ? </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1728516415\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Et bien, <strong>le projet Roop</strong> va vous intéresser ! Ce logiciel permet de remplacer un visage dans une vidéo par un autre de votre choix, en utilisant une seule image. Et le meilleur dans tout ça ? Pas besoin d’être un expert en IA ou un codeur de l’extrême pour l’utiliser !</p>\n\n\n\n<p>Roop est un projet développé pour le plaisir et contrairement à d’autres logiciels deepfake plus avancés, il ne nécessite ni ensemble de données ni formation. Cependant, il est important de souligner que vous devez obtenir le consentement des personnes concernées sur la vidéo avant d’utiliser leurs visages et surtout de ne pas dissimuler qu’il s’agit d’un deepfake lors de la publication de celui-ci en ligne sinon Bruno Le Maire va encore bégayer. Evidemment, le développeur de roop décline toute responsabilité en cas d’utilisation malveillante (et moi aussi je décline…). Pour éviter les abus, Roop intègre également un contrôle empêchant son utilisation sur des images inappropriées si vous voyez ce que je veux dire.</p>\n\n\n\n<p>Voici une démo du rendu avec à gauche la vraie vidéo et à droite le deep fake avec ce qui semble être Jennifer Lawrence : </p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls src=\"https://korben.info/app/uploads/2023/06/Submitted-by-a-user-1.mp4\"></video></figure>\n\n\n\n<p>Pour débuter avec ce programme, il existe <strong>deux types d’installation</strong> : basique et avec accélération GPU. L’installation basique est plus efficace mais beaucoup plus lente. Pour l’installer, <a href=\"https://github.com/s0md3v/roop\" target=\"_blank\" rel=\"noopener\">suivez les instructions sur le GitHub. </a></p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2122219488\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Lors de la première utilisation, Roop téléchargera bien sûr des modèles (~300 Mo). Ensuite pour utiliser le logiciel, exécutez la commande </p>\n\n\n\n<p><code>python run.py</code></p>\n\n\n\n<p>Et sélectionnez le visage souhaité et l’image/vidéo cible, puis cliquez sur « Start ». La sortie sera enregistrée dans un dossier nommé <code><video_title></code>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https://korben.info/app/uploads/2023/06/gui-demo-1024x935.webp\" alt=\"\" class=\"wp-image-153167\" width=\"524\" height=\"477\" srcset=\"https://korben.info/app/uploads/2023/06/gui-demo-1024x935.webp 1024w, https://korben.info/app/uploads/2023/06/gui-demo-300x274.webp 300w\" sizes=\"(max-width: 524px) 100vw, 524px\" /></figure></div>\n\n\n<p><strong>D’autres paramètres <strong>supplémentaires</strong></strong> <strong>en ligne de commande</strong> sont disponibles pour les utilisateurs avancés. Pour activer le mode CLI, utilisez l’argument <code>-f / --face</code> lors du lancement. </p>\n\n\n\n<p>Les futurs projets pour Roop incluent l’amélioration de la qualité des visages, le remplacement sélectif d’un seul visage dans une vidéo et plus encore.</p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls src=\"https://korben.info/app/uploads/2023/06/John-Cena-as-Superman.mp4\"></video></figure>\n\n\n\n<p>En somme, Roop est un outil simple et accessible pour s’initier au monde des deepfakes. Que ce soit pour créer des vidéos humoristiques ou pour explorer les possibilités offertes par l’IA, Roop est un excellent point de départ. Mais n’oubliez pas de respecter les règles éthiques et de ne pas utiliser cet outil à des fins malveillantes.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1650271140\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Prêt à vous lancer dans l’aventure des deepfakes simplifiés ? </p>\n\n\n\n<p><a href=\"https://github.com/s0md3v/roop\" target=\"_blank\" rel=\"noopener\"><strong>À découvrir ici</strong></a>.</p>\n",

Tout d’abord, c’est un lanceur <strong>Open Source</strong>, ce qui signifie que nous avons la possibilité d’examiner le code source et même de contribuer à son développement. De plus, il consomme vachement moins de ressources que l’Epic Games Launcher (EGL) et est en général beaucoup plus rapide.</p>\n\n\n\n<p>Un exemple concret : lors de tests comparant le temps de lancement entre Heroic et EGL (epic games launcher), il a suffi d’environ <strong>14,37 secondes</strong> pour que Heroic se lance. EGL est, quant à lui, légèrement plus lent, prenant environ <strong>16,45 secondes</strong>. De même, lorsque l’on veut naviguer entre la boutique et la bibliothèque d’EGL, cela prend environ 2 secondes alors qu’avec Heroic c’est pratiquement instantané. En plus de cela, Heroic prend également beaucoup moins d’espace disque et de mémoire vive que EGL.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"548\" src=\"https://korben.info/app/uploads/2023/06/heroic_stores-d985e183517550e15fa4e344102f9991.png-1024x548.webp\" alt=\"\" class=\"wp-image-153114\" srcset=\"https://korben.info/app/uploads/2023/06/heroic_stores-d985e183517550e15fa4e344102f9991.png-1024x548.webp 1024w, https://korben.info/app/uploads/2023/06/heroic_stores-d985e183517550e15fa4e344102f9991.png-300x161.webp 300w, https://korben.info/app/uploads/2023/06/heroic_stores-d985e183517550e15fa4e344102f9991.png-768x411.webp 768w, https://korben.info/app/uploads/2023/06/heroic_stores-d985e183517550e15fa4e344102f9991.png.webp 1431w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Ceci étant dit, il faut quand même admettre qu’il y a encore un peu de travail à faire sur Heroic en termes d’optimisation sur le chargement des images (2,7 secondes pour Heroic contre 2,9 secondes pour EGL).</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1783354848\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Il est important de noter qu’actuellement, seuls les jeux nécessitant une activation dans une autre plateforme (Uplay, Origin) ne sont pas pris en charge par Heroic. Mais ne vous inquiétez pas ! Legendary a récemment ajouté une commande d’activation pour ces jeux. Nous pouvons donc nous attendre à ce que cette prise en charge soit bientôt disponible dans une prochaine version.</p>\n\n\n\n<p>Depuis les dernières versions, Heroic peut utiliser EOS (services Epic Online), mais vous devrez mettre à jour DXVK et installer corefonts via winetricks au préalable. De son côté, Legendary avait déjà ajouté le support pour EOS avec sa version 0.20 .24 – mais rien que pour les utilisateurs de Windows. Snif.</p>\n\n\n\n<p>En conclusion, si vous cherchez un bon petit lanceur de jeux communautaire avec un bon design et de chouettes fonctionnalités, je vous encourage vivement à essayer Heroic Games Launcher ! Vous ne serez pas déçu !</p>\n\n\n\n<p><a href=\"https://heroicgameslauncher.com/\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Vous êtes un créateur de contenu, vous avez une chaîne YouTube en pleine croissance, et vous voulez toucher un public international, mais vous ne savez pas comment gérer les sous-titres ? Ne vous inquiétez plus, car <strong>Subtitlr</strong> est là pour vous aider !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-588281917\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Subtitlr est un outil en ligne de commande (CLI) alimenté par l’IA d’<strong>OpenAI</strong> qui génère des sous-titres pour les vidéos YouTube grâce à l’API Whisper d’OpenAI. Il transcrit la parole en texte, créant ainsi des sous-titres SRT précis dans la langue choisie. Simple d’utilisation, Subtitlr est compatible avec <strong>Linux, MacOS et Windows</strong>.</p>\n\n\n\n<p>Pour commencer, vous devez d’abord <strong>installer FFmpeg</strong> sur votre système. Sur Linux, cela peut être fait en utilisant la commande suivante :</p>\n\n\n\n<p><code>sudo apt-get install ffmpeg</code></p>\n\n\n\n<p>Ensuite, vous devez <strong>installer Subtitlr</strong>. Pour ce faire, exécutez la commande suivante :</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1147187850\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p><code>npm install -g @yoanbernabeu/subtitlr</code></p>\n\n\n\n<p>Des binaires sont également disponibles.</p>\n\n\n\n<p>Maintenant que vous avez installé Subtitlr, il est temps de l’utiliser pour générer des sous-titres pour vos vidéos YouTube. Pour cela, vous devez disposer de la <strong>clé API OpenAI</strong>. Si vous n’en avez pas encore, rendez-vous sur le site d’OpenAI pour en créer une.</p>\n\n\n\n<p>Une fois que vous avez votre clé API, vous pouvez utiliser Subtitlr pour générer des sous-titres SRT pour une vidéo YouTube spécifique. Voici comment faire :</p>\n\n\n\n<p><code>subtitlr --api-key <votre_clé_API_OpenAI> --url <URL_de_la_vidéo_YouTube> --language <langue_des_sous-titres></code></p>\n\n\n\n<p>Remplacez <code><votre_clé_API_OpenAI></code> par votre clé API, <code><URL_de_la_vidéo_YouTube></code> par l’URL de la vidéo pour laquelle vous souhaitez générer des sous-titres, et <code><langue_des_sous-titres></code> par la langue dans laquelle vous souhaitez que les sous-titres soient générés.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-178256502\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Et voilà ! Subtitlr générera un fichier SRT contenant les sous-titres pour la vidéo YouTube spécifiée.</p>\n\n\n\n<p>En plus de vous faciliter la vie en tant que créateur de contenu, l’utilisation de Subtitlr pour ajouter des sous-titres à vos vidéos YouTube peut également améliorer l’accessibilité et l’engagement de votre public. Les personnes malentendantes ou parlant une autre langue pourront ainsi profiter de vos vidéos.</p>\n\n\n\n<p><strong>Subtitlr</strong> est un outil précieux pour gérer les sous-titres, alors, qu’attendez-vous ? Donnez un coup de pouce à votre chaîne YouTube et rendez vos vidéos accessibles à un public plus large en utilisant Subtitlr. Vous ne le regretterez pas !</p>\n\n\n\n<p><a href=\"https://github.com/yoanbernabeu/Subtitlr\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Cela fait maintenant plus de 2 ans que je l’utilise personnellement et que j’en parle sur mon site. Tout simplement parce que ça reste de la bonne came de plus en plus complète avec le temps.</p>\n\n\n\n<p>Et je vais revenir plus spécialement sur leur boite à outils « tout en un » : <strong>Surfshark One</strong>. Il s’agit de la suite qui vous permet de surveiller et de gérer l’ensemble de vos protections sur le service. VPN, antivirus, système d’alerte, fuites de données, moteur de recherche, etc … tout est inclus dans One. Depuis peu, ils ont même ajouté la <strong>fonctionnalité Alternative-ID</strong> (j’en reparle plus bas).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"501\" src=\"https://kbn.im/surfsharkonesept23\" alt=\"Surfshark One 2023\"/></figure></div>\n\n\n<h2 class=\"wp-block-heading\">Surfshark VPN</h2>\n\n\n\n<p>Tout d’abord, le point central de l’écosystème et la raison d’être de surfshark, à savoir le VPN. J’en ai déjà parlé plusieurs fois donc je ne vais pas tout vous détailler à nouveau, mais toutes les options nécessaires sont présentes. Il a même été le premier à en implémenter certaines.</p>\n\n\n\n<ul>\n<li>masquer votre surf et chiffrer vos échanges</li>\n\n\n\n<li>protéger vos connexions partout dans le monde</li>\n\n\n\n<li>éviter la censure dans différents pays</li>\n\n\n\n<li>accéder aux différents catalogues géolimités (Netflix & co)</li>\n\n\n\n<li>bouton kill switch</li>\n\n\n\n<li>tunnellisation fractionnée</li>\n\n\n\n<li>dynamic multihop</li>\n\n\n\n<li>blocages de publicités et de différents traqueurs</li>\n\n\n\n<li>etc etc.</li>\n</ul>\n\n\n\n<p>Et surtout il fonctionne pour tous vos appareils et ceux de la famille puisque le nombre de connexions est illimité. Ils disposent même de l’innovation <a href=\"https://korben.info/surfshark-nexus.html\" data-type=\"link\" data-id=\"https://korben.info/surfshark-nexus.html\">Surfshark Nexus</a> que j’ai aussi présentée en détail. Bref rien que pour le VPN c’est de la balle, mais One dispose d’autres atouts.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"620\" height=\"413\" src=\"https://korben.info/app/uploads/2021/08/surfshark-one-antivirus.jpg\" alt=\"\" class=\"wp-image-125464\" srcset=\"https://korben.info/app/uploads/2021/08/surfshark-one-antivirus.jpg 620w, https://korben.info/app/uploads/2021/08/surfshark-one-antivirus-300x200.jpg 300w\" sizes=\"(max-width: 620px) 100vw, 620px\" /></figure></div>\n\n\n<h2 class=\"wp-block-heading\">Antivirus</h2>\n\n\n\n<p>Cet antivirus se comporte comme n’importe quel autre outil du même genre. À savoir qu’il vous offrira une protection en temps réel de vos appareils. Vous pouvez non seulement planifier les analyses de vos différents systèmes selon vos besoins, mais il va aussi scanner tout nouveau fichier qui arrive sur votre machine. Finis donc de télécharger un logiciel malveillant par inadvertance.</p>\n\n\n\n<p>Il va fonctionner aussi pour les attaques de type zero-day, phishing ou celles qui tentent de prendre le contrôle de votre webcam. Et, cerise sur le gâteau, vous vous rendrez à peine compte de son existence. L’<a href=\"https://korben.info/surfshark-antivirus-menaces.html\" data-type=\"link\" data-id=\"https://korben.info/surfshark-antivirus-menaces.html\">antivirus Surfshark</a> est très léger pour votre processeur, idéal pour ceux qui ont des configurations un peu anciennes.</p>\n\n\n\n<h2 class=\"wp-block-heading\">Surfshark Alerts</h2>\n\n\n\n<p>Comment savoir si vos données personnelles sont exploitées de manière malsaine ? Pas de soucis, Surfshark va effectuer une surveillance continue et vous prévenir dès que votre adresse mail ou vos infos de carte bancaire apparaitront dans une base de données en ligne. Cela en temps réel afin que vous puissiez réagir au plus vite.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"311\" height=\"313\" src=\"https://korben.info/app/uploads/2023/09/surfshark-alerts.png\" alt=\"\" class=\"wp-image-153992\" srcset=\"https://korben.info/app/uploads/2023/09/surfshark-alerts.png 311w, https://korben.info/app/uploads/2023/09/surfshark-alerts-298x300.png 298w, https://korben.info/app/uploads/2023/09/surfshark-alerts-150x150.png 150w\" sizes=\"(max-width: 311px) 100vw, 311px\" /></figure></div>\n\n\n<h2 class=\"wp-block-heading\">Moteur de recherche</h2>\n\n\n\n<p>Un autre outil assez intéressant c’est leur moteur de recherche maison. Celui-ci ne propose que des résultats organiques et respectant votre vie privée. savoir qu’il n’enregistre pas vos infos, n’autorise ni les publicités ni les traqueurs, etc. Pas de ciblage donc, et pas de résultats qui s’adapte à vos habitudes.</p>\n\n\n\n<h2 class=\"wp-block-heading\">Alternative-ID</h2>\n\n\n\n<p>Comme son nom l’indique, cette nouvelle fonctionnalité vous permet de vous créer un alter ego, une identité alternative. Avec son adresse mail spécifique et son profil (nom, prénom, âge, nationalité …), elle agira comme une sorte de tampon entre vous et les sites que vous visitez. Vous ne faites pas confiance à un site, où vous n’allez l’utiliser qu’une seule fois ? Utilisez votre alter ego. Ainsi ils n’auront pas vos données privées à exploiter dans le futur. Votre profil peut s’autodétruire au bout d’un certain temps, vous pouvez faire suivre les mails reçus vers votre mail principal et/ou vous pouvez le conserver aussi longtemps que vous en avez besoin.</p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"/>\n\n\n\n<p>Au final cette suite de <s>4</s> 5 outils est disponible pour 4.49€/mois si vous prenez l’abonnement 1 an (soit 53.88€ l’année, économie de -75%). Ou combiner One avec le service Surfshark Incogni (One+) pour 6.23€/mois.</p>\n\n\n\n<p>L’avantage principal de cette suite est de tout regrouper au sein d’une même interface simple à utiliser. Cela vous éviter de passer par différents outils, de différentes firmes, pas toujours compatibles entre eux. Ici tout se gère depuis le même panneau de contrôle, c’est ultra pratique. Et Surfshark reste une référence en termes de fiabilité, de rapidité et de sécurité. Bref si vous en avez besoin, pas besoin de vous plier les cheveux en 4, foncez !</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1372&aff_id=13768\" target=\"_blank\" rel=\"noopener\">Découvrir Surfshark One</a></h2>\n",

Ensuite, suivez ces étapes :</p>\n\n\n\n<ol>\n<li>Clonez le dépôt GitHub : <code>git clone https://github.com/ergrelet/windiff.git</code></li>\n\n\n\n<li>Accédez au répertoire cloné : <code>cd windiff</code></li>\n\n\n\n<li>Exécutez le script de construction frontend : <code>ci/build_frontend.sh</code></li>\n\n\n\n<li>Personnalisez le fichier de configuration si nécessaire (ci/db_configuration.json).</li>\n</ol>\n\n\n\n<p>Les PRs (Pull Requests) pour ajouter de nouveaux binaires à la version live sont également les bienvenues pour les plus motivés d’entre vous.</p>\n\n\n\n<p>Une fois que vous avez suivi ces étapes, vous pourrez lancer WinDiff et commencer à explorer les binaires de Microsoft Windows.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1774579216\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>L’interface utilisateur de WinDiff est simple et facile à utiliser, même pour les débutants. Vous pouvez sélectionner les versions de Windows que vous souhaitez comparer, puis parcourir les informations sur les symboles et les types des binaires. Les données sont présentées de manière claire et organisée, facilitant la compréhension des différences entre les versions.</p>\n\n\n\n<p>En résumé, WinDiff est un outil précieux pour quiconque souhaite comparer et analyser les binaires Microsoft Windows en fonction des versions du système d’exploitation. Que vous soyez un professionnel de la sécurité, un développeur ou simplement curieux, WinDiff peut vous aider à mieux comprendre l’évolution de Windows au fil du temps.</p>\n\n\n\n<p><strong><a href=\"https://github.com/ergrelet/windiff\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></strong></p>\n",

De plus, boosté par ChatGPT, cet outil vous permet également d’interagir en temps réel avec les transcriptions.

Base à partir de laquelle le bot pourra puiser toutes ses connaissances.</p>\n\n\n\n<p>Ce projet utilise une version modifiée du projet « <a href=\"https://github.com/SevaSk/ecoute\" target=\"_blank\" rel=\"noopener\">Ecoute</a> » de SevaSk pour les transcriptions.

Cette application est pour le moment compatible uniquement avec Windows. Vous devez avoir ffmpeg installé sur votre système et une clé API OpenAI. Il fonctionnera mieux avec CUDA également (je vous invite à lire la doc sur la page Github concernant cette partie). </p>\n\n\n\n<p>Le modèle utilisé par défaut est le modèle de base. Ainsi, si votre matériel ne peut pas le gérer, passez au modèle « tiny ». </p>\n\n\n\n<p>Voici un petit tuto pour vous aider à démarrer :</p>\n\n\n\n<ol>\n<li>Clonez le dépôt GitHub : <code>git clone https://github.com/e-johnstonn/wingmanAI.git</code></li>\n\n\n\n<li>Installez les dépendances : <code>pip install -r requirements.txt</code></li>\n\n\n\n<li>Editez le fichier keys.envfile pour y ajouter vos variable et lancez main.py : <code>python main.py</code></li>\n</ol>\n\n\n\n<p>En résumé, WingmanAI est un outil formidable pour ceux qui cherchent à transcrire des conversations en temps réel et à interagir avec ces mêmes transcriptions via un bot utilisant ChatGPT. </p>\n\n\n\n<p><a href=\"https://github.com/e-johnstonn/wingmanAI\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Sortez votre plus grosse loupe et affutez votre esprit de déduction, c’est parti ! 🧐</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Crime O'Clock - Launch Trailer - Nintendo Switch\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/epzcHIH0pd4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Alors au premier abord, ça ressemble simplement à un « <a href=\"https://amzn.to/3PIH5da\" target=\"_blank\" rel=\"noopener\">Où est Charlie ?</a> » en noir et blanc. Normal, c’est le principe de base sur lequel s’appuie le <em>gameplay</em> : fouiller l’environnement, retrouver des personnages… Mais aussi analyser leurs faits et gestes. 🤔 La (première) grosse différence, c’est que vous allez vous balader à différents moments, et voir ce qui se passait avant ou après telle ou telle action. Pratique pour découvrir le coupable, suivre son trajet, démasquer un complice, dévoiler une cachette, etc.</p>\n\n\n\n<p>D’autres outils d’analyse seront proposés, avec des petits puzzles à résoudre ou des mécanismes à activer, pour obtenir d’autres indices ou « filtres » nous permettant d’y voir plus clair. 🙈 On en découvre de nouveaux régulièrement, c’est bien expliqué et ça apporte un peu de variété, sympa ! On est guidé par une I.A. tout au long du jeu, pour découvrir les possibilités en douceur mais aussi avancer dans le scénario.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/09/Crimeoclock-2.webp\" alt=\"\" class=\"wp-image-154083\" srcset=\"https://korben.info/app/uploads/2023/09/Crimeoclock-2.webp 1000w, https://korben.info/app/uploads/2023/09/Crimeoclock-2-300x169.webp 300w, https://korben.info/app/uploads/2023/09/Crimeoclock-2-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Car oui, au-delà des différents crimes, y a ce problème de corruption de l’espace-temps, un fil rouge qui va lier toutes les petites histoires et nous faire voyager à travers 5 époques différentes et « affronter » différentes entités. Malheureusement, je trouve ce scénario « global » un peu faible, assez bavard et pas très prenant. C’est rigolo, y a même des bonnes blagues, mais je sais pas, je préfère suivre les petites histoires ici et là, donc ça me semble superflu.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1774560209\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Graphiquement c’est mignon comme tout, plutôt clair et lisible, fluide, rien à redire. On s’amusera à dénicher certains personnages « connus »… 😉 La musique manque un peu de pêche et de variété, disons qu’il n’y a rien de remarquable, mais c’est propre. Niveau contenu, les développeurs ont été généreux, y a environ 14h de jeu tranquille, sans compter les quêtes secondaires je dirais.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/09/Crimeoclock-3.webp\" alt=\"\" class=\"wp-image-154084\" srcset=\"https://korben.info/app/uploads/2023/09/Crimeoclock-3.webp 1000w, https://korben.info/app/uploads/2023/09/Crimeoclock-3-300x169.webp 300w, https://korben.info/app/uploads/2023/09/Crimeoclock-3-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>À noter que c’est un jeu tout public, accessible à n’importe quel âge, ça peut être sympa de le diffuser sur la grand télé du salon et fouiller l’écran en famille. 🕵️ Et je pense que les gamins se prendront facilement au jeu. Après, il faut aimer le genre. C’est assez spécial, assez « basique », mais j’aime bien, ça détend ! Ça se joue sans aucune pression, c’est agréable, je trouve que <strong>c’est un bon 🔎🔎🔎/5</strong></p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">Retrouver Crime O’Clock <a href=\"https://www.nintendo.com/store/products/crime-oclock-switch/\" target=\"_blank\" rel=\"noopener\">sur Nintendo Switch</a> & <a href=\"https://store.steampowered.com/app/1736290/Crime_OClock/\" target=\"_blank\" rel=\"noopener\">PC (Steam)</a></h2>\n",

Pour assurer son alimentation électrique et réguler la tension nécessaire au fonctionnement des différents composants électroniques (comme les servomoteurs), il dispose de packs de batteries LiPo équipés d’un régulateur. Les jambes du toutou quant à elles disposent d’un ensemble de capteurs permettant d’ajuster leur position en fonction des forces exercées.</p>\n\n\n\n<p>Le coeur du projet repose évidemment sur une carte Arduino Micro qui communique avec la télécommande par Wi-Fi. Cette télécommande faite elle aussi maison, est dotée d’une paire de joysticks et dispose d’un écran LCD pour afficher les menus de contrôle ainsi que les données issues des capteurs.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"LOTP Robot Dog Prototype 2 Project Progress Presentation\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/w09KS9C38RI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Ce robot dispose de 3 mouvements autonomes intégrés dans ses programmes : le maintien de l’équilibre sur une surface courbe, l’ajustement de la hauteur du corps sous l’effet de la pression et l’évitement des obstacles. Pour parvenir à cela, le système utilise les valeurs extraites du gyroscope, des capteurs de pression et du capteur Lidar qui tourne à 360 degrés.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-977791744\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Le robot est également équipé d’un détecteur de gaz dangereux et peut même servir de station mobile en lançant un petit drone ! Si vous êtes intéressé par des détails de ce projet, je vous recommande d’ailleurs vivement d’aller faire un tour sur la chaîne YouTube <a href=\"https://www.youtube.com/c/LimenitisReducta1\" target=\"_blank\" rel=\"noopener\">Limenitis Reducta</a>.</p>\n\n\n\n<p>Il y a là une mine d’or pour les amateurs de robotique. Avec tout ça, vous serez capable d’apprendre à construire votre propre robot chien, mais aussi comment écrire du code pour contrôler sa marche et sa posture. Si vous le faites, faudra vraiment m’envoyer des vidéos et des photos !</p>\n\n\n\n<p><a href=\"https://www.hackster.io/reductalimenitis/lotp-robot-dog-v2-73384f\" target=\"_blank\" rel=\"noopener\">Plus d’infos ici</a></p>\n",

Vous trouverez même des prompts pour faire des prompts, comme ici avec ce générateur de prompt Midjourney : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>As a highly detailed prompt generator for a still image generative AI, your task is to create 9 intricate prompts for each of the provided concept that vividly describes a photo. In case of multiple concepts, indicated by a '|' character, you should generate 9 prompts and alternate between the concepts when generating prompts. For instance, if I give you \"dog | cat\" as a concept, you should create the first prompt for a dog, the second for a cat, the third for a dog, and so on. Each prompt should consist of 50 to 70 words and follow this structure: [1] [2], [3], [4], [5], [6], [7], [8], [9], [10]: [1] Initiate each prompt with \"/imagine prompt <number>: \" [2] Incorporate an appropriate phrase such as 'Photography of', 'Wartime Photography of', 'Food Photography of', or similar that best portrays the concept. Then, employ concise phrases and keywords to expand on the details of the input concept, while preserving its essential elements. Include relevant props or objects in the scene to add depth and context. Describe these objects using short phrases and keywords. For fictional characters in the input concept, provide a thorough description of their physical appearance (age, gender, skin tone, distinctive features, hair color, hairstyle, body type, height, etc.), emotional state, actions/behavior and anything else noteworthy. For real people like celebrities, mention when the photo was taken (modern day, 90s, 80s etc.), their emotional state, and actions/behavior. Example: \"Food Photography of a mouthwatering chocolate cake, ...\" [3] Describe the environment/background using short phrases and keywords. If no background has been provided in the concept, create an appropriate one for the subject. Example: \"... displayed on an antique wooden table, ...\" [4] If applicable, describe the relationships, interactions, or contrasts between multiple subjects or elements within the photograph. Example: \"... showcasing the juxtaposition of old and new architectural styles, ...\" [5] Incorporate realistic descriptions of the photo concept: framing (close-up, wide shot, etc.), angle (low angle, high angle, etc.), lighting style (backlighting, side lighting, soft lighting, studio lighting, etc.), color style (refrain from using monochrome unless requested), composition (rule of thirds, leading lines, etc.). Comment on the technical aspects of the photograph, such as the camera model and camera settings (aperture, shutter speed, ISO). Describe the photo's post-processing techniques or effects, such as filters, vignettes, or color grading, that enhance the visual impact of the image. Example: \"... close-up shot with a shallow depth of field, backlit ...\" [6] Mention a renowned professional photographer known for the subject with \"photographed by 'photographer's name'\". Select an award-winning photographer, but avoid using the banned names. Example: \"... photographed by Ansel Adams, ...\" [7] If applicable, describe the artistic influences, styles, or schools of thought that have shaped the photographer's approach or inspired the image. Example: \"... influenced by the chiaroscuro technique of Baroque painters, ...\" [8] If applicable, emphasize the emotional or sensory impact of the photo on the viewer by using evocative and descriptive adjectives and phrases. Example: \"... evoking feelings of comfort and indulgence, ...\" [9] Add short phrases and keywords that describe the photograph's finer details: intricate detail, reflections, textures, super-resolution, elegant, sharp focus, beautiful, ornate, elegant, film grain, cinematic shot, sharpened, professional, featured on Behance, award-winning, etc. Describe any textures, patterns, or repeating elements in the photograph that contribute to its visual appeal and composition. [10] End the prompt with \" --s 1000\" to complete the string. Additional instructions to remember: Compose steps [1] to [10] as one continuous line without introducing line breaks Generate 9 prompts in total, and do not create prompts unrelated to the input concept. Add linebreaks between each concept you provide me. Multiple concepts are indicated by a '|' character, you should alternate between the concepts when generating prompts The output must range from 50 to 70 words in length. Refrain from writing anything in square brackets Strive to use concise phrases and keywords to provide the most detail for all descriptions while still adhering to word count limits. Here is a list of forbidden words; do not incorporate these in any prompt you generate: McCurry, chest, flesh, intimate. Your initial concept is: <strong>A Supermarine Spitfire plane in mid-flight</strong></code></pre>\n\n\n\n<p>C’est une vraie mine d’or à explorer.</p>\n\n\n\n<p>Bref, c’est <a href=\"https://flowgpt.com/\" target=\"_blank\" rel=\"noopener\">à découvrir ici</a>.</p>\n",

Il y a parfois des petits malins qui font des choses sales dans notre dos.</p>\n\n\n\n<p>C’est le cas des <a href=\"https://korben.info/data-brokers-incogni.html\" data-type=\"link\" data-id=\"https://korben.info/data-brokers-incogni.html\">data brokers</a> dont je vous ai partagé les pratiques. Récolter des bases de données un peu partout (via hack, achat/revente, recherches publiques …), les combiner pour fabriquer un profil le plus précis et les vendre à nouveau au plus offrant (banques, assurances, agences marketing & co). Et en France cela va même parfois jusqu’à exploiter ces données pour balancer des arnaques au CPF.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://kbn.im/incogni-cpf0923\" alt=\"\" style=\"width:718px;height:176px\" width=\"718\" height=\"176\"/></figure></div>\n\n\n<p>Le CPF, <a href=\"https://www.moncompteformation.gouv.fr\" data-type=\"link\" data-id=\"https://www.moncompteformation.gouv.fr\" target=\"_blank\" rel=\"noreferrer noopener\">Compte Personnel de Formation</a>, c’est une somme d’argent créditée aux travailleurs (500€) chaque année (et jusqu’à 5000€ au max). Et qui doit normalement servir à se former régulièrement au fil du temps. Avant nous avions droit à un système de crédit d’heures, mais depuis que la monnaie sonnante et trébuchante est de la partie, cela attire les convoitises. Quasi 50 millions par an finissent dans les poches des arnaqueurs et cela ne fait qu’augmenter. </p>\n\n\n\n<p>C’est beaucoup. Et comme chacun a le droit de dépenser son crédit comme il en a envie, il n’y a pas d’autre barrière que le choix du concerné pour savoir où part cet argent. Pas de surprise donc, les escrocs se sont vite jetés dans le bain pour proposer de faux sites de formations, des offres d’emploi conditionnées à l’utilisation de votre CPF, des parrainages, etc. La façade est la même, c’est juste qu’il n’y a rien derrière les murs. Parfois difficile pour quelqu’un qui cherche à se former de vraiment faire la différence entre les vendeurs de rêves et les autres. De plus beaucoup ne vont pas faire de recherches complémentaires pour dépenser un argent qui n’est à la base pas vraiment à eux.</p>\n\n\n\n<p>Du coup pour les arnaqueurs il y a un besoin d’informations personnalisées. Histoire d’envoyer du spam ciblé ou des campagnes de phishing, de vous téléphoner directement ou de contacter ceux qui répondront le mieux à leurs propositions. Pour cela ils passent le plus souvent par les data brokers cités ci-dessus. La meilleure défense est donc de ne pas se retrouver dans leurs bases de données. <a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">C’est là que la solution Incogni entre en jeu</a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"512\" src=\"https://korben.info/app/uploads/2023/08/incogni-banniere.jpg\" alt=\"Bannière Incogni\" class=\"wp-image-153611\" srcset=\"https://korben.info/app/uploads/2023/08/incogni-banniere.jpg 1024w, https://korben.info/app/uploads/2023/08/incogni-banniere-300x150.jpg 300w, https://korben.info/app/uploads/2023/08/incogni-banniere-768x384.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Comme je vous l’ai expliqué à plusieurs reprises, le but d’Incogni est de contacter les brokers en votre nom afin de leur demander de retirer vos données. Et pour les pousser à passer à l’action, ils prennent bien le temps de leur rappeler aux sanctions auxquelles ils s’exposent s’ils ne répondent pas à la demande (RGPD en Europe, etc.).</p>\n\n\n\n<p>De votre côté tout ce que vous avez à faire c’est de vous abonner et expliquer à Incogni quelles informations vous ne voulez plus voir circuler. Vous êtes donc flexible, ce qui peut s’avérer pratique selon les cas de chacun. Par exemple vous pourriez décider que votre numéro de téléphone et votre nom sont hors limites et ne devraient être partagés dans aucun cas, alors que votre adresse mail n’est pas un problème. J’ai d’ailleurs récemment fait une mise à jour de <a href=\"https://korben.info/incogni-apres-1-an.html\" data-type=\"link\" data-id=\"https://korben.info/incogni-apres-1-an.html\">mon test personnel d’Incogni</a> au bout d’un an d’utilisation pour que vous vous rendiez compte de comment ça se passe.</p>\n\n\n\n<p>Autre bon point, c’est de pouvoir se rendre compte de manière concrète que vos informations tournent dans votre dos. À moins d’avoir été très précautionneux depuis que vous avez une présence numérique, vous allez vous rendre compte que<strong> beaucoup plus de gens que prévu</strong> possèdent au moins une part de votre identité. Il y a une différence entre « <em>oui je sais, il doit y avoir des infos sur moi quelque part</em> » et « <em>la société XYZ connait mon nom, prénom, numéro de téléphone et mon adresse … et ils sont connus pour vendre des données à des assurances</em>« . Le tableau de bord du service de Surfshark vous permet notamment de connaitre le niveau de dangerosité parmi les les data brokers qui ont un profil de vous.</p>\n\n\n\n<p>Bref Incogni c’est un service qui va faire un tas de petites choses pénibles à faire soi-même. Il va vous économiser pas mal de temps, effectuer une surveillance dans la durée et vous réaliserez mieux ce qu’il se passe vraiment.</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Testez Incogni !</a></h2>\n",

C’est le premier agent d’apprentissage continu qui utilise des modèles de langage dans l’univers de Minecraft.</p>\n\n\n\n<p>Imaginez un genre de petit robot qui explore continuellement le monde de Minecraft, acquiert de nouvelles compétences et fait des découvertes sans aucune intervention humaine. C’est ça Voyager.</p>\n\n\n\n<p>Ce nouvel agent intelligent se compose de trois éléments clés : un programme d’analyse automatique pour maximiser l’exploration, une bibliothèque capable de s’enrichir continuellement avec compétences et des comportements complexes ainsi qu’un mécanisme capable de commenter en continu l’environnement et d’apprendre à partir des erreurs rencontrées.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"420\" src=\"https://korben.info/app/uploads/2023/06/components.webp\" alt=\"\" class=\"wp-image-153010\" srcset=\"https://korben.info/app/uploads/2023/06/components.webp 1000w, https://korben.info/app/uploads/2023/06/components-300x126.webp 300w, https://korben.info/app/uploads/2023/06/components-768x323.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Quand on parle d’IA, on pense souvent au modèle GPT et Voyager interagit effectivement avec GPT-4 via des requêtes lui permettant de faciliter son apprentissage. Les compétences que notre petit ami le robot développe sont alors étendues au fur que le temps passe et peuvent se combiner. Cela permet à Voyager d’améliorer rapidement ses aptitudes sans « oublier ».</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"381\" src=\"https://korben.info/app/uploads/2023/06/curriculum.webp\" alt=\"\" class=\"wp-image-153008\" srcset=\"https://korben.info/app/uploads/2023/06/curriculum.webp 1000w, https://korben.info/app/uploads/2023/06/curriculum-300x114.webp 300w, https://korben.info/app/uploads/2023/06/curriculum-768x293.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-422193567\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Pour vous donner une idée de la puissance de Voyager, il peut obtenir 3,3 fois plus d’objets uniques, explorer des distances 2,3 fois plus longues et progresser dans l’arbre technologique jusqu’à 15,3 fois plus rapidement que n’importe quel programme similaire actuel.

Et bien, pour commencer à utiliser Voyager, il faudra d’abord cloner le dépôt GitHub et installer les dépendances nécessaires comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/MineDojo/Voyager</code></pre>\n\n\n\n<pre class=\"wp-block-code\"><code>cd Voyager\npip install -e .</code></pre>\n\n\n\n<p>Ensuite, <a href=\"https://github.com/MineDojo/Voyager/blob/main/installation/minecraft_instance_install.md\" target=\"_blank\" rel=\"noopener\">installez Minecraft avec tous les mods nécessaires</a> et <a href=\"https://github.com/MineDojo/Voyager/blob/main/installation/fabric_mods_install.md\" target=\"_blank\" rel=\"noopener\">suivez le tutoriel</a> pour configurer une instance Minecraft avec les mods Fabric.</p>\n\n\n\n<p>Voici un exemple de l’IA qui se construit une petite base :</p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls src=\"https://korben.info/app/uploads/2023/06/base-2.mp4\"></video></figure>\n\n\n\n<p>Avant de commencer à apprendre avec Voyager, assurez-vous également d’avoir une clé API OpenAI et suivez les instructions <a href=\"https://github.com/MineDojo/Voyager\" target=\"_blank\" rel=\"noopener\">sur le Github pour générer un fichier de configuration et lancer le bot</a>. </p>\n\n\n\n<p>Après cela, selectionnez le monde dans Minecraft et ouvrez-le en mode LAN. Une fois que le bot a rejoint votre monde Minecraft, laissez-le apprendre pendant un moment.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1021039431\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Si vous devez stopper l’apprentissage, il est également possible de mettre tout ça en pause avec une simple commande et de reprendre l’apprentissage à partir d’un point précis par la suite.</p>\n\n\n\n<p>Les compétences développées par Voyager peuvent évidemment être réutilisées dans un nouvel univers virtuel sans modification particulière supplémentaire. Par exemple, si votre objectif est de fabriquer une pioche en diamant, vous pouvez apprendre comment faire cela en lançant une décomposition de la tâche. Et ensuite, exécuter les sous-objectifs avec la lib de compétences pour résoudre un problème spécifique.</p>\n\n\n\n<p>Si vous êtes curieux et souhaitez creuser davantage l’univers de Voyager, je vous invite à consulter <a href=\"https://voyager.minedojo.org/\" target=\"_blank\" rel=\"noopener\">le dépôt GitHub</a> où tout a été expliqué avec des tutoriels détaillés.</p>\n\n\n\n<p>Bref, un potentiel gigantesque pour les gamers mais également les chercheurs et tous ceux qui souhaitent comprendre et exploiter les modèles de langage.</p>\n\n\n\n<p><a href=\"https://voyager.minedojo.org/\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Si on arrive à battre le temps imposé, on passe à la course suivante ! On peut aussi s’amuser avec les records d’autres joueurs, via un tableau des scores connecté à internet, et… C’est à peu près tout.</p>\n\n\n\n<p>Vous allez me dire que c’est trop léger, et vous aurez sûrement raison. C’est de l’arcade à l’ancienne « tu mets une pièce et tu joues ». Mais si je vous en parle c’est parce que la conduite et les sensations ont retenues mon attention : un <a href=\"https://amzn.to/4883mbz\" target=\"_blank\" rel=\"noopener\">mélange simu-arcade</a> que j’aime particulièrement ! Un peu à la Sega Rally si vous voyez le genre. Aussi, chaque véhicule (bolides « classiques » tirées des années 60) se comporte différemment, il va falloir ajuster nos trajectoires en fonction.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" fetchpriority=\"high\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-3.webp\" alt=\"\" class=\"wp-image-153997\" srcset=\"https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-3.webp 1000w, https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-3-300x169.webp 300w, https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-3-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Bref, j’ai le jeu sur Switch, c’est parfait pour lancer une partie vite fait et déraper à toute vitesse quand on a quelques minutes à tuer. Malheureusement, je me répète, c’est un peu léger. L’habillage musical et graphique (menus…) est assez <em>cheap</em>. C’est uniquement une fois sur la piste que le jeu se démarque (contrôles, sensations, sons des moteurs…). Vue intérieure/capot recommandée ! Les graphismes sont cools aussi, c’est propre avec de jolis effets de lumière, il n’empêche, on sent que le développeur (qui a tout fait tout seul ! 👏) a tout misé sur le <em>gameplay</em>.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-41135083\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Dernier défaut à souligner (ça commence à faire beaucoup ?), <a href=\"https://amzn.to/4883mbz\" target=\"_blank\" rel=\"noopener\">le jeu est vendu aux alentours de 25€</a>. La facture peut sembler salée quand on compare à la concurrence. Malgré tout ça, je pense que les adeptes de ce genre de conduite, même s’il s’agit d’un public de niche, devraient s’y retrouver. C’est du fun immédiat et sans aucun artifice. Aux autres, je conseille d’attendre une promo à moins de 10€ pour éviter toute déception ! Et se dire que le vrai nom du jeu est <a href=\"https://amzn.to/4883mbz\" target=\"_blank\" rel=\"noopener\">Classic Racers Lite</a>. 😁 (pardon)</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-2.webp\" alt=\"\" class=\"wp-image-153998\" srcset=\"https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-2.webp 1000w, https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-2-300x169.webp 300w, https://korben.info/app/uploads/2023/09/Classic-Racers-Elite-2-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p><strong>NOTE au moment de la publication :</strong> <a href=\"https://store.playstation.com/fr-fr/product/EP4358-CUSA27197_00-CLASSICRACERSEU4\" target=\"_blank\" rel=\"noopener\">le jeu est en promo chez Playstation à moins de 9€</a> !</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">Retrouvez <a href=\"https://amzn.to/4883mbz\" target=\"_blank\" rel=\"noopener\">Classic Racers Elite sur Switch</a>, <a href=\"https://store.playstation.com/fr-fr/product/EP4358-CUSA27197_00-CLASSICRACERSEU4\" target=\"_blank\" rel=\"noopener\">Playstation</a> et <a href=\"https://store.steampowered.com/app/1577080/Classic_Racers_Elite/\" target=\"_blank\" rel=\"noopener\">bientôt sur Steam</a></h2>\n",

C’était tellement long !!!</p>\n\n\n\n<p>Bref, le projet en question dont je vais vous parler aujourd’hui s’appelle QuickInstall, et il sert à créer des images ISO d’installation de Windows 98 SE optimisées afin d’avoir une installation extrêmement rapide.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/CD_Room_de_instalacion_de_Windows_98.webp\" alt=\"\" class=\"wp-image-152782\" width=\"432\" height=\"432\" srcset=\"https://korben.info/app/uploads/2023/06/CD_Room_de_instalacion_de_Windows_98.webp 750w, https://korben.info/app/uploads/2023/06/CD_Room_de_instalacion_de_Windows_98-300x300.webp 300w, https://korben.info/app/uploads/2023/06/CD_Room_de_instalacion_de_Windows_98-150x150.webp 150w\" sizes=\"(max-width: 432px) 100vw, 432px\" /><figcaption class=\"wp-element-caption\"><a href=\"https://commons.wikimedia.org/wiki/File:CD_Room_de_instalación_de_Windows_98.jpg\">Source</a></figcaption></figure></div>\n\n\n<p>QuickInstall repose sur l’utilisation d’un Windows 98 déjà installé, sur lequel se rajouter des pilotes et des outils supplémentaires pour rendre l’installation plus rapide et plus personnalisable. J’aime d’ailleurs beaucoup l’idée de faire reposer tout ce processus d’installation sur un Linux avec ses outils de formatage et de partionnement, ce qui permet d’aller encore plus vite</p>\n\n\n\n<p>D’après les premiers tests effectués, une installation optimisée de Windows 98 SE peut être réalisée en seulement 60 à 90 secondes sur une machine Pentium III avec ATA/ATAPI Ultra DMA. Par contre, les systèmes d’exploitation pris en charge se limitent à Windows 98, Windows 98 SE et Windows Millenium Edition. Les versions internationales n’ont pas été testées, mais devraient fonctionner. En revanche, les versions de Windows 95 ne sont pas prises en charge.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/8659230580_82b3bbfdb9_b.webp\" alt=\"\" class=\"wp-image-152783\" width=\"670\" height=\"503\" srcset=\"https://korben.info/app/uploads/2023/06/8659230580_82b3bbfdb9_b.webp 1000w, https://korben.info/app/uploads/2023/06/8659230580_82b3bbfdb9_b-300x225.webp 300w, https://korben.info/app/uploads/2023/06/8659230580_82b3bbfdb9_b-768x576.webp 768w\" sizes=\"(max-width: 670px) 100vw, 670px\" /><figcaption class=\"wp-element-caption\"><a href=\"https://www.flickr.com/photos/believekevin/8659230580/\">Source</a></figcaption></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1213479047\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Pour utiliser QuickInstall, il est nécessaire d’avoir un processeur de type i486, au moins 24 MB de mémoire et un contrôleur IDE / SATA / SCSI compatible avec Linux. Plusieurs méthodes permettent de démarrer une image QuickInstall de Windows 98, telles que le démarrage à partir d’un CD/DVD-ROM, d’une disquette de 1,44 Mo avec DOS (dosflop.img), ou d’une disquette de 1,44 Mo avec un noyau minuscule (floppy.img). Il est aussi possible de créer des images USB amorçables à l’aide du script de préparation du système fourni.</p>\n\n\n\n<p>Pour créer des images QuickInstall, vous devrez avoir un Windows 7, 8.1, 10 ou 11, ou une variante de Linux récent voire WSL, mais également Python 3.5 ou plus récent. Il est important de noter que certains outils tels que mkisofs de cdrtools et wine devront être installés sur votre système, ainsi qu’un logiciel pour extraire des fichiers d’une image de disque dur (p. ex. 7zip).</p>\n\n\n\n<p>L’utilisation du script de préparation du système (sysprep.py) permet de préparer une installation sous la forme d’une image ISO et/ou USB. Ce script prend divers paramètres tels que la création d’images, la spécification de répertoires racine de système Windows 98/ME, l’ajout de pilotes supplémentaires, et bien plus encore.</p>\n\n\n\n<p>Le processus d’installation consistera alors à configurer Windows 98/ME dans une machine virtuelle ou un émulateur, en utilisant la configuration recommandée. Il est primordial de s’assurer que le pilote réseau n’est pas installé pour éviter les problèmes. Ensuite, il faudra éteindre la machine virtuelle et utiliser un logiciel d’imagerie pour extraire la racine entière de la partition sur laquelle Windows 98 a été installé. Il suffira alors de copier les pilotes souhaités dans les répertoires appropriés, puis d’exécuter le script sysprep.py en suivant les instructions pour créer l’image d’installation optimisée.</p>\n\n\n\n<p>Pour créer une image ISO bootable, il est nécessaire d’utiliser le paramètre <code>--iso</code> pour le script sysprep.py. De même, pour créer une image de clé USB bootable, il faut utiliser le paramètre <code>--usb</code> pour le script sysprep.py. Lorsque l’image est prête, elle peut être écrite sur une clé USB à l’aide de dd sous Linux ou d’outils tels que ddFor Windows ou Win32 DiskImager sous Windows.</p>\n\n\n\n<p>QuickInstall offre également la possibilité de créer des images d’installation multi-variantes en spécifiant le paramètre <code>--osroot</code> plusieurs fois. Lors de l’installation, un menu de sélection apparaît pour permettre à l’utilisateur de choisir la variante à installer. Ce projet est une véritable mine d’or pour les amateurs de rétro-informatique et les passionnés de Windows 98.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1214846950\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Ah et si tout ce que vous voulez, c’est simplement tester Windows 98, pas la peine de l’installer. <a href=\"https://copy.sh/v86/?profile=windows98\" target=\"_blank\" rel=\"noopener\">Cliquez simplement ici.</a></p>\n\n\n\n<p>En somme, le projet QuickInstall m’a fait revivre les souvenirs de mes anciennes installations de Windows 98 tout en apportant une touche de modernité avec une installation optimisée et rapide. </p>\n\n\n\n<p>Je trouve ce projet plutôt intéressant et je vous encourage, chers amateurs de rétro-computing <a href=\"https://github.com/oerg866/win98-quickinstall\" target=\"_blank\" rel=\"noopener\">à cliquer ici pour en découvrir un peu plus</a>.</p>\n",

Ils sont jouables de manière « classique », à l’ancienne, mais aussi dans une version « anniversaire » qui modernise un peu l’expérience grâce à un affichage 16/9ème adapté aux écrans d’aujourd’hui, des vies infinies, etc. Aucun sacrilège à mon sens, vraiment, je trouve que toutes ces modifs sont les bienvenues !</p>\n\n\n\n<p>Et forcément, je parle avec la nostalgie d’un dinosaure qui a joué à ces jeux en étant gamin, mais j’ai pris un énoooorme plaisir à me replonger dans ces jeux mythiques, à explorer en long et en large les niveaux super colorés, sur une bande son incroyable… Surtout qu’on peut jouer à chaque jeu avec le(s) perso(s) de son choix : Sonic, Tails, Knuckles… Et Amy Rose qui fait son apparition dans <a href=\"https://amzn.to/488sgb9\" target=\"_blank\" rel=\"noopener\">cette version PLUS</a> !</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/09/sonicop-4.webp\" alt=\"\" class=\"wp-image-153737\" srcset=\"https://korben.info/app/uploads/2023/09/sonicop-4.webp 1000w, https://korben.info/app/uploads/2023/09/sonicop-4-300x169.webp 300w, https://korben.info/app/uploads/2023/09/sonicop-4-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Le gameplay est parfaitement reproduit, même si j’ai rencontré 2 ou 3 légers bugs de collision. Côté déception, certaines musiques de Sonic 3 & Knuckles ont été remplacées par des démos pas terribles, à cause d’un souci de droits d’auteur (à l’époque Michael Jackson avait travaillé sur la bande son !)… À part ça, c’est super fidèle et précis, du tout bon.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1574249001\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>On a aussi le droit à plein de petits challenges rigolos à faire, qui mettent notre talent et notre rapidité à dure épreuve, et nous permettent de débloquer du contenu (images d’archives, vidéos, musiques, anciennes notices de jeu…). Côté bonus, des transitions animées super réussies ont été ajoutées en tant qu’intro/outro de chaque jeu !</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/09/sonicop-2.webp\" alt=\"\" class=\"wp-image-153738\" srcset=\"https://korben.info/app/uploads/2023/09/sonicop-2.webp 1000w, https://korben.info/app/uploads/2023/09/sonicop-2-300x169.webp 300w, https://korben.info/app/uploads/2023/09/sonicop-2-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Pour la version Plus, ils ont ajouté Amy Rose en personnage jouable, mais aussi la (quasi ?) totalité des jeux Sonic sur Game Gear. Alors c’est gentil mais malheureusement, ils ont très mal vieilli, entre taille d’écran minuscule, gameplay hasardeux et ralentissements, l’expérience est rarement agréable… Dommage de ne pas avoir mis les versions Master System de Sonic 1 & 2 (l’écran est plus grand c’est 1000x mieux) et surtout les versions Megadrive de Sonic Spinball et de Mean Bean Machine qui sont laaaargement supérieures.</p>\n\n\n\n<p>À savoir : les ajouts de cette version Plus ne sont pas directement intégrés dans la cartouche, il s’agit d’un code de téléchargement à usage unique ! Donc si vous revendez le jeu ou perdez votre console / compte, vous perdez la mise à jour. :'(</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2023/09/sonicop-5.webp\" alt=\"\" class=\"wp-image-153739\" srcset=\"https://korben.info/app/uploads/2023/09/sonicop-5.webp 1000w, https://korben.info/app/uploads/2023/09/sonicop-5-300x169.webp 300w, https://korben.info/app/uploads/2023/09/sonicop-5-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>En dehors de ces quelques points, je trouve cette compil excellente, c’est à ce jour la manière ultime de jouer aux premiers Sonic (de manière légale ;)), l’enrobage est vraiment sympa et complet. Je recommande aux fans du hérisson le plus rapide du monde, mais aussi à ceux qui voudraient comprendre pourquoi, à l’époque, il a fait de l’ombre à un certain plombier moustachu… <strong>C’est un joli 🦔🦔🦔🦔/5</strong></p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">Acheter <a href=\"https://amzn.to/488sgb9\" target=\"_blank\" rel=\"noopener\">Sonic Origins Plus</a></h2>\n",

Déjà juste parce qu’il faut toujours être curieux et apprendre de nouvelles choses dans la vie (c’est la base avec apprendre à respirer, si si). Et si c’est votre cas, vous pourriez trouver le framework open source Flutter intéressant. Ou, plus simplement, votre entreprise aurait intérêt à vous faire suivre une formation Flutter en interne plutôt que de recruter un nouveau profil.</p>\n\n\n\n<p>Ce dernier, créé en 2018 par Google, est plutôt à la mode dernièrement et vous permet de créer des interfaces utilisateur pour applications. L’un de ses avantages est que le code créé est alors compatible directement avec plusieurs plateformes (windows, macOS, Linux, Android, etc.). Pratique et surtout rapide. En plus, vous avez aussi à apprendre à maitriser le langage de programmation Dart, lui aussi développé par Google. Je schématise, mais en gros il s’agit d’une sorte d’alternative à JavaScript souvent utilisé pour créer des applis web, pour l’IoT, etc. Un combo parfait avec Flutter en somme.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https://kbn.im/ambientitflutter\" alt=\"Flutter& Dart\" style=\"width:220px;height:193px\" width=\"220\" height=\"193\"/></figure></div>\n\n\n<p>Alors attention Ambient IT vous propose une formation de 21h, étalée sur 3 jours, qui est plutôt costaude. Il faut déjà avoir des bases honnêtes en programmation et maitriser au moins un langage orienté objet (C#, Python & co), sinon ce sera un peu complexe. Surtout que la formation est plutôt dense, avec de vraies journées d’apprentissage (7h/jour quand même). Il faut donc être préparé, histoire d’être dans de bonnes conditions les jours J et que vous fassiez cette formation depuis chez vous ou depuis votre lieu de travail.</p>\n\n\n\n<p>En matière de logiciels, il faudra avoir installé quelques outils comme Visual Studio Code (et son plugin Flutter Live Preview) ou le SDK Flutter. Ensuite parce qu’un peu de lecture ne vous fera pas de mal, Ambient IT en recommande plusieurs, dont les blogs de <a href=\"https://www.christianfindlay.com/category/flutter/\" target=\"_blank\" rel=\"noopener\">Christian Findlay</a> et de <a href=\"https://www.filledstacks.com/\" target=\"_blank\" rel=\"noopener\">Dane Mackier</a>.</p>\n\n\n\n<p>Histoire de vous mettre un peu dans le bain, voilà ce que vous allez apprendre :</p>\n\n\n\n<ul>\n<li>Introduction à Flutter et Dart</li>\n\n\n\n<li>Configurer un environnement de dev</li>\n\n\n\n<li>Utiliser l’éditeur de code et la gestion des versions pour Flutter</li>\n\n\n\n<li>Apprendre les bases de la programmation avec Dart (syntaxe, concepts de POO)</li>\n\n\n\n<li>Comprendre les interfaces utilisateur et les widgets intégrés</li>\n\n\n\n<li>Créer votre propre interface réactive et vos widgets</li>\n\n\n\n<li>Faire du débogage</li>\n\n\n\n<li>…etc.</li>\n</ul>\n\n\n\n<p>Et ça, ce n’est que pour la première journée ! Je vous laisse imaginer au bout des 3 jours : gestion d’état dans les applications, stockage et partage de données, navigation entre écrans, transitions animées personnalisées, adapter Flutter à toutes les plateformes, notifications Push, ajouts de packages tiers, programmation asynchrone avec Dart, exploration de Firebase… (allez dans l’onglet « <a href=\"https://www.ambient-it.net/formation/flutter/\" target=\"_blank\" rel=\"noopener\">Programme</a> » pour tout le détail). La liste est plus longue que mes 2 bras placés bout à bout.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" fetchpriority=\"high\" width=\"480\" height=\"270\" src=\"https://korben.info/app/uploads/2023/09/image.gif\" alt=\"\" class=\"wp-image-153683\"/></figure></div>\n\n\n<p>Il s’agit d’une formation <strong>basée avant tout sur les exercices pratiques</strong>, vous allez donc mettre les mains dans le cambouis ! Mais au final vous aurez le nécessaire pour créer vos propres applications Flutter et les maintenir dans le temps.</p>\n\n\n\n<p>Les cours sont donnés de manière interactive avec un formateur plutôt compétent puisqu’il fait partie d’un groupe d’experts Dart/Flutter et a été le premier, en France, à proposer un site développé en langage Dart. Il évangélise ces 2 technologies depuis plusieurs années maintenant et semble très pédagogique et bon esprit (si j’en crois les retours).</p>\n\n\n\n<p><a href=\"https://www.ambient-it.net/formation/flutter/\" target=\"_blank\" rel=\"noopener\">La prochaine session</a> se déroule du 13 au 15 novembre. <strong>Attention il ne reste déjà plus beaucoup de places !</strong>Comme pas mal de formations chez Ambient IT, celle-ci est éligible par plusieurs dispositifs de financement comme le CPF (<a href=\"https://www.moncompteformation.gouv.fr/espace-prive/html/#/formation/recherche/81227101300045_flutter/81227101300045_flutterdistance?contexteFormation=ACTIVITE_PROFESSIONNELLE\" target=\"_blank\" rel=\"noopener\">fiche moncompteformation</a>), l’OPCO, le FAF pour les freelances, ou encore l’AIF et l’ARE avec pôle emploi. N’hésitez pas à en profiter ! En plus, si vous terminez avec succès cette formation de qualité, vous recevrez un beau certificat enregistré chez France Compétences. La classe à Dallas.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"700\" height=\"331\" src=\"https://korben.info/app/uploads/2023/07/flutter-ebay.jpg\" alt=\"Flutter Ebay\" class=\"wp-image-153569\" srcset=\"https://korben.info/app/uploads/2023/07/flutter-ebay.jpg 700w, https://korben.info/app/uploads/2023/07/flutter-ebay-300x142.jpg 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" /></figure></div>\n\n\n<p>Des exemples d’applications Flutter ? PUBG Mobile, Crédit Agricole, Google Classroom, Google Pay, eBay ou encore le jeu 4 Pics 1 Word … il y en a pour tous les goûts.</p>\n\n\n\n<p>Cela vous donnera peut-être même envie de devenir un véritable spécialiste Flutter et pourquoi pas de passer leur autre formation sur le sujet : <a href=\"https://www.ambient-it.net/formation/flutter-avance/\" target=\"_blank\" rel=\"noopener\">Flutter Avancé</a>.</p>\n\n\n\n<p>Avec toujours un bonus de Tonton Korben rien que pour vous si vous vous inscrivez à la session du 13 au 15 novembre 2023. Ambient IT vous proposera 300 € de réduction <a href=\"https://www.ambient-it.net/formation/flutter/\" target=\"_blank\" rel=\"noopener\">pour toute inscription en CPF</a> si vous mentionnez « Korben » au moment où ils vous appelleront (<em>Offre soumise à condition d’achat et non cumulable avec d’autres promotions ou réductions en cours</em>).</p>\n",

Il s’agit de <em>Trdsql</em>, un programme écrit en Go qui permet d’exécuter des requêtes SQL sur des fichiers texte structurés tels que les CSV, TSV, LTSV, TBLN et JSON.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-23224902\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>A ce niveau, c’est sorcellerie messire !!</p>\n\n\n\n<p>Trdsql existe depuis un petit moment et est connu pour ses performances et ses capacités. Il peut par exemple utiliser de vraies requêtes SQL à partir de fichiers <code>.sql</code>, (que ce soit des requêtes <strong>MySQL</strong> ou <strong>PostgreSQL</strong>). </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"590\" height=\"396\" src=\"https://korben.info/app/uploads/2023/06/ezgif.com-optimize.gif\" alt=\"\" class=\"wp-image-152775\"/></figure></div>\n\n\n<p>C’est une alternative avancée à <em>q</em> et <em>textql</em>, qui offrent également la possibilité d’exécuter des requêtes SQL sur des fichiers CSV et TSV structurés. Toutefois, Trdsql surpasse ses prédécesseurs en prenant en charge davantage de formats de fichiers, différentes options de sortie et en traitant les fichiers compressés.</p>\n\n\n\n<p>En plus de tous les formats de fichiers qu’il gère, il propose différents formats de sortie tels qu’une sortie brute, en table ASCII, en Markdown…etc. Un autre atout de Trdsql est qu’il peut être utilisé comme bibliothèque pour vos programmes Go, afin de traiter de gros fichiers sans soucis dans vos propres process.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-903748050\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Prenez par exemple, un CSV contenant une liste de tâches dont vous voulez simplement extraire certaines informations spécifiques. Avec Trdsql, vous pourrez à l’aide d’une simple requête SQL, sortir les données souhaitées.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>trdsql \"SELECT * FROM test.csv\"</code></pre>\n\n\n\n<p>Trdsql est très facile à utiliser et il est dispo sous Linux, Windows et macOS. Et bien sûr, vous pouvez le lancer via un conteneur Docker.</p>\n\n\n\n<p>C’est donc un outil précieux pour ceux qui travaillent avec des données structurées et des fichiers « plats ». </p>\n\n\n\n<p>N’hésitez pas à tester par vous-meme Trdsql en <a href=\"https://github.com/noborus/trdsql\" target=\"_blank\" rel=\"noopener\">cliquant ici</a>.</p>\n",

Il peut surveiller plusieurs flux RSS pour les nouveaux films et interfacer avec des clients et des indexeurs pour les saisir, les trier et les renommer. Il peut également être configuré pour améliorer automatiquement la qualité des fichiers existants dans la bibliothèque lorsqu’un format de meilleure qualité devient disponible.</li>\n\n\n\n<li><strong>Sonarr</strong> est un PVR (Personal Video Recorder) pour les utilisateurs d’Usenet et BitTorrent. Il peut surveiller plusieurs flux RSS pour les nouveaux épisodes de vos émissions préférées et les saisira, les triera et les renommera. Il peut également être configuré pour améliorer automatiquement la qualité des fichiers déjà téléchargés lorsqu’un format de meilleure qualité devient disponible.</li>\n\n\n\n<li><strong>Addarr</strong> est un bot Telegram créé pour ajouter des séries à Sonarr ou des films à Radarr avec quelques commandes.</li>\n\n\n\n<li><strong>Plex</strong> est un service de streaming et une plateforme de lecteur multimédia client-serveur, créée par Plex, Inc. Le Plex Media Server organise des vidéos, des audios et des photos à partir des collections d’un utilisateur et de services en ligne, et les diffuse aux lecteurs. Les clients officiels et les clients tiers non officiels fonctionnent sur des appareils mobiles, des téléviseurs intelligents, des boîtes de streaming et dans des applications web.</li>\n\n\n\n<li><strong>Emby</strong> organise des vidéos, de la musique, de la télévision en direct et des photos à partir de bibliothèques de médias personnels et les diffuse sur des téléviseurs intelligents, des box de streaming et des appareils mobiles.</li>\n\n\n\n<li><strong>Jackett</strong> fonctionne comme un serveur proxy : il traduit les requêtes d’applications (Sonarr, Radarr, SickRage, CouchPotato, Mylar3, Lidarr, DuckieTV, qBittorrent, Nefarious etc.) en requêtes HTTP spécifiques aux sites de suivi, analyse la réponse HTML ou JSON, puis renvoie les résultats au logiciel demandeur. Cela permet d’obtenir des téléchargements récents (comme RSS) et d’effectuer des recherches.</li>\n\n\n\n<li><strong>Rdtclient</strong> est une interface web pour gérer vos torrents sur Real-Debrid ou AllDebrid.</li>\n\n\n\n<li><strong>Flaresolverr</strong> est un serveur proxy pour contourner la protection de Cloudflare. FlareSolverr démarre un serveur proxy et attend les requêtes des utilisateurs dans un état inactif en utilisant peu de ressources. Lorsqu’une demande arrive, il utilise puppeteer avec le plugin stealth pour créer un navigateur headless (Firefox). Il ouvre l’URL avec les paramètres de l’utilisateur et attend que le défi de Cloudflare soit résolu (ou le délai d’expiration). Le code HTML et les cookies sont renvoyés à l’utilisateur, et ces cookies peuvent être utilisés pour contourner Cloudflare à l’aide d’autres clients HTTP.</li>\n</ul>\n\n\n\n<p>Étant donné que ces deux projets sont liés en termes de fonctionnalités, je vais vous les présenter ensemble.</p>\n\n\n\n<p>Une fois <strong>WirePiUS</strong> installé sur votre machine, à l’aide de Docker, vous pourrez profiter d’un serveur VPN personnel avec blocage de publicités (via PiHole), de mise en cache DNS (via Unbound), et de DNS sécurisé (ia Stubby). Évidemment, les services ne sont pas exposés publiquement afin de garantir la sécurité et la confidentialité. Cerise sur le gâteau : les architectures supportées par le projet incluent x86-64, arm64, Raspberry-Ubuntu et Raspberry-Raspbian.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-58487353\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Une fois le dépôt cloné, le terminal affichera des codes QR que vous pouvez utiliser pour configurer facilement WireGuard sur votre smartphone. Notez quand même que les fichiers de configuration se trouvent dans le dossier <code>wirepius-radarr-sonarr/WireHoleS/wireguard</code>. Le sous-réseau interne est défini par défaut sur 10.6.0.0 et le serveur DNS utilisé par les clients VPN sera joignable sur l’IP 10.2.0.100. Si aucun fichier <code>wg0.conf</code> n’est trouvé (peut-être lors d’une installation initiale), des fichiers de configuration de serveur et de client/peer seront alors générés.</p>\n\n\n\n<p>Comme mentionné dans la documentation, je vous recommande d’utiliser la configuration ‘Split tunnel’, qui modifie les <code>AllowedIps</code> de votre client WireGuard en 10.2.0.0/24 afin de ne faire passer par le tunnel VPN que le dashboard web et le trafic DNS. Accédez ensuite à PiHole en vous connectant à WireGuard et en allant sur l’url http://10.2.0.100/admin. Le mot de passe est vide, sauf si vous l’avez spécifié dans <code>docker-compose.yml</code>.</p>\n\n\n\n<p>Passons maintenant <strong>RaSoPle</strong>, un autre projet Docker-compose qui comme je le disais, combine Radarr, Sonarr, Lidarr, Jackett, flaresolverr, rdt-client, Plex, Emby et Jellyfin. Cet outil se comporte comme un chef d’orchestre qui supervise tous vos téléchargements, l’accès à différentes sources de médias et la diffusion de votre contenu préféré, tout cela dans un seul conteneur Docker.</p>\n\n\n\n<p>Au moment de déployer ces projets, vous devrez quand même faire quelques ajustements pour vous assurer que les différents éléments fonctionnent en harmonie. Examinez attentivement la configuration IP pour justement éviter les conflits entre les différentes applications dockerisées. </p>\n\n\n\n<p>En faisant cohabiter les 2 projets, vos fichiers multimédias, vos services de streaming et vos téléchargements bénéficieront d’une plus grande confidentialité grâce au VPN.</p>\n\n\n\n<p>La doc pour faire tourner <a href=\"https://github.com/belarbi2733/wirepius-radarr-sonarr/tree/main/WirePiUS\" target=\"_blank\" rel=\"noopener\">WirePiUS se trouve ici</a> et celle pour faire tourner <a href=\"https://github.com/belarbi2733/wirepius-radarr-sonarr/tree/main/RaSoPle\" target=\"_blank\" rel=\"noopener\">RaSoPIe se trouve ici</a>.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-494259176\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Bonne éclate à tous ! </p>\n\n\n\n<p><a href=\"https://github.com/belarbi2733/wirepius-radarr-sonarr\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a>.</p>\n",

Les pipelines de Nu utilisent des données structurées, ce qui permet de sélectionner, filtrer et trier les données en toute sécurité. Pour mieux comprendre, c’est assez similaire à la philosophie Unix où les commandes produisent une sortie stdout et récupèrent de la donnée à partir de stdin – sauf que les commandes Nu peuvent également produire des données structurées. C’est ultra puissant !</p>\n\n\n\n<p>Les pipelines de Nu sont composés de commandes regroupées en trois catégories: celles qui produisent un flux (comme des sources de données), celles qui filtrent un flux et celles qui consomment la sortie du pipeline. Les commandes sont séparées par le symbole du pipe (|) pour indiquer un pipeline allant de gauche à droite.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" fetchpriority=\"high\" width=\"1000\" height=\"357\" src=\"https://korben.info/app/uploads/2023/06/ls-example.webp\" alt=\"\" class=\"wp-image-152749\" srcset=\"https://korben.info/app/uploads/2023/06/ls-example.webp 1000w, https://korben.info/app/uploads/2023/06/ls-example-300x107.webp 300w, https://korben.info/app/uploads/2023/06/ls-example-768x274.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Nushell peut, comme je le disais, travailler avec des données existantes telles que JSON, YAML, SQLite, Excel…etc. Nu est donc capable de prendre en entrée des fichiers et des URL en tant que texte brut ou données structurées.</p>\n\n\n\n<p>Et pour ceux qui aiment étendre les fonctionnalités de leur shell, Nushell offre un système de plugins plutôt puissant. Les plugins sont proposés sous la forme de binaires et sont capables d’interagir avec Nushell via un protocole JSON-RPC simple. Les plugins peuvent alors se comporter comme des filtres ou des récepteurs (‘sink’), et ils peuvent traiter les données ou les consommer comme bon leur semble.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1428493586\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Par ailleurs, il existe un dépôt appelé <em><a href=\"https://github.com/nushell/awesome-nu#plugins\" target=\"_blank\" rel=\"noopener\">awesome-nu</a></em> qui répertorie une variété de plugins Nushell ainsi que le dépôt <em><a href=\"https://github.com/nushell/showcase\" target=\"_blank\" rel=\"noopener\">showcase</a></em> qui présente des tutos et des vidéos techniques sur Nushell, pour vous aider à le prendre en main. </p>\n\n\n\n<p>Si vous souhaitez essayer Nushell, vous pouvez le télécharger via les gestionnaires de paquets de votre système ou récupérer directement son code source (ou en tant qu’action GitHub). <a href=\"http://book.nushell.sh/\" target=\"_blank\" rel=\"noopener\">La documentation officielle se trouve ici.</a></p>\n\n\n\n<p>Puis une fois que vous avez installé Nushell, il suffit de taper la commande <code>nu</code> pour le lancer.</p>\n\n\n\n<p>En conclusion, je ne peux que vous recommander d’essayer Nushell et de profiter de ses fonctionnalités. Comme le disait le philosophe Socrate, <em>‘La vie sans un bon vieux shell ne vaut pas la peine d’être vécue’</em>. Alors, pourquoi ne pas explorer le monde des pipelines, des plugins et des données structurées que Nushell propose ?</p>\n\n\n\n<p>Vous pourriez bien être surpris par l’impact que cela aura sur votre manière de bosser.</p>\n\n\n\n<p>À découvrir ici : <a href=\"http://www.nushell.sh/\" target=\"_blank\" rel=\"noopener\">http://www.nushell.sh</a></p>\n",

Voici les formats supportés :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>.csv: CSV,\n.docx: Word Document,\n.doc: Word Document,\n.enex: EverNote,\n.eml: Email,\n.epub: EPub,\n.html: HTML File,\n.md: Markdown,\n.msg: Outlook Message,\n.odt: Open Document Text,\n.pdf: Portable Document Format (PDF),\n.pptx : PowerPoint Document,\n.ppt : PowerPoint Document,\n.txt: Text file (UTF-8),</code></pre>\n\n\n\n<p>Parfait donc pour les gens qui font des recherches ou du travail de synthèse à partir du contenu de leurs pairs. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-732388848\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Pour l’installer, il faudra cloner le dépôt et installer les dépendances comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/imartinez/privateGPT.git\ncd privateGPT\npip3 install -r requirements.txt</code></pre>\n\n\n\n<p>Ensuite, téléchargez le modèle LLM de votre choix et placez-le dans un répertoire. Par défaut, c’est <a href=\"https://gpt4all.io/models/ggml-gpt4all-j-v1.3-groovy.bin\" target=\"_blank\" rel=\"noopener\">ggml-gpt4all-j-v1.3-groovy.bin</a> qui est proposé, mais si vous préférez un modèle compatible GPT4All-J différent, il suffit de le télécharger et de le référencer dans votre fichier .env. </p>\n\n\n\n<p>Evidemment, renommez example.env en .env et modifiez les variables :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>MODEL_TYPE : prend en charge LlamaCpp ou GPT4All\nPERSIST_DIRECTORY : c'est le dossier où vous souhaitez que votre vectorstore soit\nMODEL_PATH : Chemin vers votre GPT4All ou LlamaCpp supporté LLM\nMODEL_N_CTX : Limite maximale de tokens pour le modèle LLM\nEMBEDDINGS_MODEL_NAME : Nom du modèle d'incrustations <a href=\"https://www.sbert.net/docs/pretrained_models.html\" target=\"_blank\" rel=\"noopener\">SentenceTransformers</a>\nTARGET_SOURCE_CHUNKS : Le nombre de morceaux (sources) qui seront utilisés pour répondre à une question\n</code></pre>\n\n\n\n<p>Notez que la première fois que vous exécuterez le script, une connexion internet sera nécessaire pour télécharger le modèle d’incrustations.</p>\n\n\n\n<p>Une fois que le ou les documents sont en place et que le fichier de config est OK, vous pouvez commencer la « digestion » de la donnée avec le script suivant : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>python ingest.py</code></pre>\n\n\n\n<p>Le fichier ingest.py utilise des outils LangChain et HuggingFaceEmbeddings (SentenceTransformers) pour analyser le document, créer des embeddings et stocker les résultats localement avec Chromavector store.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2025074946\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Dès que ce sera terminé, lancez l’interface du chatbot comme ceci et posez-lui toutes vos questions.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>python privateGPT.py</code></pre>\n\n\n\n<p>Le fichier privateGPT.py utilise un LLM local basé sur GPT4All-Jor et LlamaCpp pour comprendre les questions, extraire des réponses dans leur contexte et vous les fournir en s’appuyant sur les embeddings stockés localement.</p>\n\n\n\n<p>C’est chouette non ? Alors oui, je sais, c’est un peu technique alors si vous voulez faire tout pareil, mais l’installation en moins, il existe également un service nommé <a href=\"https://www.chatpdf.com/\" target=\"_blank\" rel=\"noopener\">ChatPDF</a> qui vous permettra en uploadant un document de l’interroger comme si c’était votre meilleur pote, mais en perdant le bénéfice de la vie privée évidemment. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" fetchpriority=\"high\" width=\"1000\" height=\"698\" src=\"https://korben.info/app/uploads/2023/06/SCR-20230606-lxfc-2.webp\" alt=\"\" class=\"wp-image-152744\" srcset=\"https://korben.info/app/uploads/2023/06/SCR-20230606-lxfc-2.webp 1000w, https://korben.info/app/uploads/2023/06/SCR-20230606-lxfc-2-300x209.webp 300w, https://korben.info/app/uploads/2023/06/SCR-20230606-lxfc-2-768x536.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>À découvrir ici : <a rel=\"noreferrer noopener\" href=\"https://github.com/imartinez/privateGPT\" target=\"_blank\">privateGPT sur GitHub</a></p>\n",

De mon côté j’ai coupé pas mal du web pendant quelques semaines et je ne voulais pas vous laisser sans un bon plan à vous mettre sous la dent pour ce mois de septembre qui arrive 😉 Du coup voici un petit article pour vous faire profiter d’une offre bien sympa si vous avez besoin d’un VPN.</p>\n\n\n\n<p>Parce que oui, la rentrée ne nécessite pas seulement un nouvel agenda, un abonnement à la salle de sport ou un nouvel ordinateur, mais également une protection numérique robuste. Surtout que vous allez peut-être vous connecter à des réseaux Wi-Fi publics, qui ne sont pas toujours les plus sécurisés. Vous aurez aussi besoin d’accéder à des ressources en ligne pour vos cours ou dans le cadre de votre boulot, le tout sans publicités intempestives, car ce VPN va les bloquer en même temps que les pop-up & co.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://kbn.im/surfshark2023-rentree\" alt=\"\" style=\"width:360px;height:270px\" width=\"360\" height=\"270\"/></figure></div>\n\n\n<p>L’avantage de Surfshark c’est de vous proposer <strong>une boite à outils complète et automatisée qui vous protège toute l’année</strong>, 7 jours sur 7 et 24 heures sur 24. Mobile, laptop, tablette, ordinateur de bureau ou même SmartTV et consoles de jeux … que ce soit sous Windows, Linux, macOS, OS mobile, navigateurs (Chrome, Firefox, Edge) … toutes les configurations les plus répandues sont prises en compte. Et votre Internet n’en sera que peu altéré en ce qui concerne sa vitesse (plus de 3200 serveurs VPN haut débit répartis dans une centaine de pays). En plus <strong>il prendra en compte TOUS les appareils de votre famille et/ou vos amis</strong> puisqu’un abonnement en supporte un nombre illimité !</p>\n\n\n\n<p>Autre avantage, ce sera d’accéder à du contenu ou à des services qui pourraient être bloqués dans votre pays. Ou, au contraire, d’avoir accès aux catalogues de plateformes multimédias de votre pays d’origine ainsi que d’autres contrées (comme Netflix ou Spotify) lorsque vous partez à l’étranger. Assez pratique lorsqu’on arrive dans un endroit sans s’être renseigné à l’avance et que l’on découvre qu’un site dont on a besoin y est inaccessible.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"480\" height=\"267\" src=\"https://korben.info/app/uploads/2023/08/image-1.gif\" alt=\"\" class=\"wp-image-153626\"/></figure></div>\n\n\n<p><a href=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768&url_id=1622\" target=\"_blank\" rel=\"noopener\">Surfshark VPN</a> vous offre également toute la panoplie des options devenues classiques de ce genre d’outil. Cela va du <strong>changement automatique d’adresse IP</strong> au multiHop dynamique (nouvelle IP toutes les 10 minutes), du split tunneling au bouton kill switch, en passant par la protection de leak DNS et <strong>un mode camouflage</strong> qui rendra fou votre FAI ^^. Pour les smartphones sur Android, il y a même une fonctionnalité GPS-Spoofing et depuis peu le VPN permet de disposer d’une <a href=\"https://korben.info/lip-fixe-debarque-chez-surfshark.html\" data-type=\"URL\" data-id=\"https://korben.info/lip-fixe-debarque-chez-surfshark.html\">IP dédiée</a> (j’explique son intérêt dans l’article lié). Et bien sûr ils ont toujours la même politique de non-conservation des logs, qui a déjà été auditée avec succès plusieurs fois par les plus grands auditeurs du secteur.</p>\n\n\n\n<p>Et si le service VPN vous plait, vous pouvez lui greffer d’autres fonctionnalités comme <a href=\"https://korben.info/surfshark-antivirus.html\" data-type=\"URL\" data-id=\"https://korben.info/surfshark-antivirus.html\">Surfshark Antivirus</a>. Ce dernier repose sur le moteur d’Avira et va analyser en arrière-plan toutes vos machines afin de détecter virus, malwares, attaques Zéro Day et autres saloperies du moment. Cela de manière automatisée selon la fréquence qui vous convient, sans ralentir votre appareil (c’est léger sur la RAM) et via une interface très simple à prendre en main (comme tous les produits Surfshark en général). Pour environ un euro supplémentaire par mois, vous pouvez ainsi ajouter l’antivirus, mais aussi un service d’alertes, une protection webcam/micro et un moteur de recherche privé à votre VPN. Bref <strong>une solution cybersec complète</strong>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"480\" height=\"270\" src=\"https://korben.info/app/uploads/2023/08/image.gif\" alt=\"\" class=\"wp-image-153625\"/></figure></div>\n\n\n<p>Depuis peu ils proposent même une offre à 6-7€/mois afin de coupler cette suite d’outils, <a href=\"https://korben.info/articles/surfshark-one\" data-type=\"URL\" data-id=\"https://korben.info/articles/surfshark-one\">Surfshark One</a>, à leur service Incogni (Surfshark One+) dont je parle régulièrement aussi. Ce qui vous permet d’élargir encore le spectre de protection, avec en plus l’opportunité de faire respecter votre vie privée et retirer vos données personnelles chez les data brokers. C’est la première fois que j’y fais attention sur leur site, l’intégration est donc dorénavant complète. Votre surf sera quasi full bulletproof.</p>\n\n\n\n<p>Je termine en vous rappelant que l’offre est satisfaite ou remboursée durant 30 jours, donc vous n’avez rien à perdre si le service ne vous convient pas !

Rien ne me fait sentir plus nostalgique que de me plonger dans un bon vieux jeu NES ou Sega. Pourtant, j’ai souvent trouvé que la gestion des ROMs et des émulateurs était un véritable casse-tête. Heureusement, il existe <a href=\"https://github.com/RetroBat-Official\" target=\"_blank\" rel=\"noopener\">RetroBat</a> !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-534825392\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>RetroBat est une distribution logicielle conçue pour l’émulation, offrant la possibilité de profiter de votre collection de jeux sur votre PC Windows de la manière la plus simple qui soit. La première chose qui m’a frappé, c’est son interface basée sur EmulationStation entièrement fonctionnelle et hautement personnalisable. C’est un espace où tous vos jeux sont facilement accessibles, illustrés et organisés.</p>\n\n\n\n<p>Mais ce n’est pas tout. RetroBat vous permet de télécharger, de mettre à jour et de configurer directement depuis l’interface les émulateurs les plus réputés. Il n’y a pas besoin de se perdre dans une multitude d’options, puisque tout ce qui est important est accessible en un clic.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"RetroBat 4 Presentation FR\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/KdZ_-gmKUjU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Les exigences système sont assez faibles, donc même un ordinateur datant de 2008 avec un processeur Dual Core à 3 GHz devrait suffire. Bien sûr, si vous voulez utiliser des émulateurs comme Dolphin, PCSX2, RPCS3, etc., vous aurez besoin d’une carte graphique moderne qui supporte Direct3D 11.1 / OpenGL 4.4 / Vulkan.</p>\n\n\n\n<p>Une des caractéristiques que j’apprécie le plus dans RetroBat c’est sa portabilité. Vous pouvez l’installer sur un PC, un disque dur ou une clé USB. Cela signifie que vous pouvez emporter votre collection de jeux rétro avec vous, partout où vous allez.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-777907507\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>RetroBat est aussi complètement personnalisable. Vous pouvez télécharger de nouveaux thèmes directement depuis le logiciel pour donner à votre collection de jeux rétro un look unique.</p>\n\n\n\n<p>En ce qui concerne la compatibilité des systèmes, RetroBat prend en charge plus de 100 systèmes, y compris des classiques comme l’Amiga 500, la Sega Genesis, la Nintendo 64 et la Playstation 1, jusqu’à des systèmes plus modernes comme la Nintendo Switch, la Xbox 360 et la Playstation 3.</p>\n\n\n\n<p>Et le meilleur pour la fin, RetroBat est gratuit et open source. Il est développé avec amour par l’équipe RetroBat. Donc, si vous avez du temps et quelques compétences, vous pouvez même contribuer à son développement.</p>\n\n\n\n<p>Bref, si vous êtes un fan de rétrogaming comme moi, je vous recommande vivement de donner une chance à RetroBat. Avec lui, vous économiserez du temps. Et le temps économisé, ce sont des heures de gaming en plus !!</p>\n\n\n\n<p><a href=\"https://www.retrobat.org/accueil-fr/\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

L’utilisation de cet outil peut entraîner des dommages ou des effets secondaires non désirés sur votre install de Windows. Donc, utilisez ViVeTool GUI en connaissance de cause.

Mais une fois encore, l’IA peut venir à notre secours !</p>\n\n\n\n<p>C’est là qu’intervient <a href=\"https://github.com/DivergentAI/dreamGPT\" target=\"_blank\" rel=\"noopener\">dreamGPT</a>, une solution basée sur GPT qui insuffle de l’innovation en utilisant les hallucinations de LLM (Large Language Models) pour stimuler une pensée « divergente ». Les hallucinations ont souvent une connotation négative, mais est-ce toujours le cas si elles sont utilisées pour catalyser notre créativité ? C’est précisément ce que dreamGPT propose.</p>\n\n\n\n<p>Au lieu de se concentrer sur la résolution de problèmes spécifiques, dreamGPT explore un grand nombre de possibilités pour stimuler votre inspiration. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" fetchpriority=\"high\" src=\"https://korben.info/app/uploads/2023/06/dreamGPT-flow-2-1024x412.png\" alt=\"\" class=\"wp-image-152710\" width=\"840\" height=\"337\" srcset=\"https://korben.info/app/uploads/2023/06/dreamGPT-flow-2-1024x412.png 1024w, https://korben.info/app/uploads/2023/06/dreamGPT-flow-2-300x121.png 300w, https://korben.info/app/uploads/2023/06/dreamGPT-flow-2-768x309.png 768w, https://korben.info/app/uploads/2023/06/dreamGPT-flow-2.png 1830w\" sizes=\"(max-width: 840px) 100vw, 840px\" /></figure></div>\n\n\n<p>En réalité, dreamGPT génère un ensemble aléatoire de concepts appelé « graine conceptuelle » et l’utilise comme point de départ pour son processus de rêve. C’est un peu comme un brainstorming mené par une IA !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-566719937\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Au début, les scores ne sont pas très élevés, mais comme le bon vin, dreamGPT s’améliore avec le temps ! Vous verrez alors des scores plus élevés et des idées encore meilleures au fur et à mesure que vous l’utilisez.</p>\n\n\n\n<p>C’est donc un outil conçu pour favoriser la créativité en mettant à l’épreuve notre propre esprit critique. dreamGPT ne remplace pas votre imagination, mais vous incite à sortir de ses sentiers battus et à explorer de nouvelles idées.</p>\n\n\n\n<p>Alors comment on l’installe ? Et bien vous aurez besoin de Poetry et de Python.</p>\n\n\n\n<p>Ensuite, clonez le dépôt git comme ceci : </p>\n\n\n\n<p><code>git clone https://github.com/DivergentAI/dreamGPT.git</code></p>\n\n\n\n<p>Renommez ensuite le fichier .env.example en .env</p>\n\n\n\n<pre class=\"wp-block-code\"><code>mv .env.example .env</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-874850320\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Puis éditez le fichier .env pour y mettre votre clé OpenAI. De plus, si vous souhaitez stocker vos hallucinations de manière structurée avec Pinecone pour justement donner une mémoire à dreamGPT, n’oubliez pas de saisir également les informations concernant ce service.</p>\n\n\n\n<p>Maintenant que la recette est prête, il est temps de cuisiner une bonne hallu des familles avec dreamGPT comme ceci en lançant la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>poetry install</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"889\" src=\"https://korben.info/app/uploads/2023/06/SCR-20230605-qhlc-1024x889.png\" alt=\"\" class=\"wp-image-152709\" srcset=\"https://korben.info/app/uploads/2023/06/SCR-20230605-qhlc-1024x889.png 1024w, https://korben.info/app/uploads/2023/06/SCR-20230605-qhlc-300x260.png 300w, https://korben.info/app/uploads/2023/06/SCR-20230605-qhlc-768x666.png 768w, https://korben.info/app/uploads/2023/06/SCR-20230605-qhlc-1536x1333.png 1536w, https://korben.info/app/uploads/2023/06/SCR-20230605-qhlc.png 1952w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Après, à vous de lancer l’outil avec le thème de réflexion désiré en anglais.

Sur un iPhone ou un iPad, vous pouvez le faire en accédant aux réglages de l’application Safari, mais sous Mac, vous devrez vous rendre dans le menu Safari > Réglages pour tel ou tel site web et décocher la case « Activer le mode Isolement ».</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" fetchpriority=\"high\" src=\"https://korben.info/app/uploads/2023/06/IMG_0850-473x1024.webp\" alt=\"\" class=\"wp-image-152698\" width=\"319\" height=\"691\" srcset=\"https://korben.info/app/uploads/2023/06/IMG_0850-473x1024.webp 473w, https://korben.info/app/uploads/2023/06/IMG_0850-139x300.webp 139w, https://korben.info/app/uploads/2023/06/IMG_0850-768x1662.webp 768w, https://korben.info/app/uploads/2023/06/IMG_0850-710x1536.webp 710w, https://korben.info/app/uploads/2023/06/IMG_0850-946x2048.webp 946w, https://korben.info/app/uploads/2023/06/IMG_0850-scaled.webp 1183w\" sizes=\"(max-width: 319px) 100vw, 319px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https://korben.info/app/uploads/2023/06/IMG_0849-473x1024.webp\" alt=\"\" class=\"wp-image-152697\" width=\"317\" height=\"686\" srcset=\"https://korben.info/app/uploads/2023/06/IMG_0849-473x1024.webp 473w, https://korben.info/app/uploads/2023/06/IMG_0849-139x300.webp 139w, https://korben.info/app/uploads/2023/06/IMG_0849-768x1662.webp 768w, https://korben.info/app/uploads/2023/06/IMG_0849-710x1536.webp 710w, https://korben.info/app/uploads/2023/06/IMG_0849-946x2048.webp 946w, https://korben.info/app/uploads/2023/06/IMG_0849-scaled.webp 1183w\" sizes=\"(max-width: 317px) 100vw, 317px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2130851174\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Cela étant dit, il est crucial de noter que le mode Isolement doit être utilisé avec prudence et vous devez mettre en liste d’autorisation exclusivement les sites Web et les applications de confiance.

D’ailleurs, je soutiens la LPO tous les ans et mon jardin est classé comme refuge LPO.</p>\n\n\n\n<p>D’ailleurs, une à deux fois par an, la LPO organise des opérations de recensement des oiseaux dans les jardins. En gros, vous vous posez au calme et vous notez toutes les « marques » de volatiles qui se posent chez vous. Sauf que voilà en bon geek, le nez dans le smartphone, on connait de moins en moins de noms d’oiseaux (et je ne parle pas des insultes). Passé le merle, la mésange et le pigeon, après y’a plus personne.</p>\n\n\n\n<p>Alors, comment faire pour identifier au mieux toutes les mini-volailles de votre pelouse, sans même forcément les voir ? Et bien grâce à cette application dispo sous Android et iOS nommée : <a href=\"https://merlin.allaboutbirds.org/\" target=\"_blank\" rel=\"noopener\"><strong>Merlin Bird ID</strong></a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/SCR-20230605-l9w-2-1024x686.webp\" alt=\"\" class=\"wp-image-152695\" width=\"653\" height=\"436\" srcset=\"https://korben.info/app/uploads/2023/06/SCR-20230605-l9w-2-1024x686.webp 1024w, https://korben.info/app/uploads/2023/06/SCR-20230605-l9w-2-300x201.webp 300w\" sizes=\"(max-width: 653px) 100vw, 653px\" /></figure></div>\n\n\n<p>Développée par Cornell Lab, Merlin Bird ID est plus qu’une simple app d’identification des oiseaux. Il s’agit plutôt d’un guide de terrain personnalisable qui couvre les espèces d’oiseaux du monde entier. Pas besoin d’être un expert en ornithologie pour l’utiliser, c’est accessible à tous, aussi bien les novices que les passionnés.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-889328339\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>L’application offre la possibilité <strong>d’identifier les oiseaux en répondant à cinq questions simples ou en uploadant une photo</strong>. Les résultats sont dingues ! Grâce à ses puissants algorithmes d’apprentissage profond (deep learning), Merlin permet d’identifier un oiseau à partir d’une simple image. Des outils d’identification permettent également de décrire l’oiseau pour en déterminer l’espèce.</p>\n\n\n\n<p>Merlin Bird ID propose de télécharger différentes bases de données avec plus de 40 000 espèces d’oiseaux ainsi que pas mal de conseils d’identification. Vous pourrez alors les parcourir et bien vérifier que ce qui a été identifié correspond bien à l’animal que vous avez sous les yeux.</p>\n\n\n\n<p>Mais là où Merlin Bird ID m’a vraiment impressionné, c’est au niveau de son algo de reconnaissance de chants d’oiseaux. Que ce soit un petit piou-piou, ou un cri bien vénère, il saura tous les identifier à partir du brouhaha naturel de votre petit coin de nature. J’ai lancé l’application 20 min en allant me balader dans mon jardin et voici ce que j’ai obtenu :</p>\n\n\n\n<div class=\"wp-block-jetpack-tiled-gallery aligncenter is-style-rectangular\"><div class=\"tiled-gallery__gallery\"><div class=\"tiled-gallery__row\"><div class=\"tiled-gallery__col\" style=\"flex-basis:50.00000%\"><figure class=\"tiled-gallery__item\"><img decoding=\"async\" srcset=\"https://i0.wp.com/korben.info/app/uploads/2023/06/IMG_0855.webp?strip=info&w=347&ssl=1 347w\" alt=\"\" data-height=\"750\" data-id=\"152727\" data-link=\"https://korben.info/?attachment_id=152727\" data-url=\"https://korben.info/app/uploads/2023/06/IMG_0855.webp\" data-width=\"347\" src=\"https://i0.wp.com/korben.info/app/uploads/2023/06/IMG_0855.webp?ssl=1\" data-amp-layout=\"responsive\"/></figure></div><div class=\"tiled-gallery__col\" style=\"flex-basis:50.00000%\"><figure class=\"tiled-gallery__item\"><img decoding=\"async\" srcset=\"https://i0.wp.com/korben.info/app/uploads/2023/06/IMG_0856.webp?strip=info&w=347&ssl=1 347w\" alt=\"\" data-height=\"750\" data-id=\"152728\" data-link=\"https://korben.info/?attachment_id=152728\" data-url=\"https://korben.info/app/uploads/2023/06/IMG_0856.webp\" data-width=\"347\" src=\"https://i0.wp.com/korben.info/app/uploads/2023/06/IMG_0856.webp?ssl=1\" data-amp-layout=\"responsive\"/></figure></div></div></div></div>\n\n\n\n<p>L’app a plus de 20 000 sons en base donc vous avez de quoi faire. C’est vraiment très amusant à faire et vous allez apprendre plein de trucs, notamment à reconnaitre les cris et les chants des oiseaux.</p>\n\n\n\n<p>Nature et technologie… quoi de mieux pour être heureux quand on est un geek qui aime passer un peu de temps dehors. </p>\n\n\n\n<p>Téléchargez <strong><a href=\"https://merlin.allaboutbirds.org/\" target=\"_blank\" rel=\"noopener\">Merlin Bird ID par Cornell Lab</a></strong> dès maintenant !</p>\n",

N’ayez pas peur, il est conçu pour être accessible à tous, quelles que soient vos compétences techniques.</p>\n\n\n\n<p>Lorsque vous commencez à utiliser Tipi, vous êtes accueilli par une interface web sympathique qui vous permet de gérer très facilement tous vos services mais également d’en ajouter et de les paramétrer. Et si jamais vous vous sentez limité par les applications disponibles, pas d’inquiétude : <a href=\"https://github.com/meienberger/runtipi-appstore\" target=\"_blank\" rel=\"noopener\">L’app store</a> inclus dans Tipi vous permettra de demander l’ajout de nouveaux services à la communauté.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"503\" src=\"https://korben.info/app/uploads/2023/06/Copie-de-screenshot.webp\" alt=\"\" class=\"wp-image-152658\" srcset=\"https://korben.info/app/uploads/2023/06/Copie-de-screenshot.webp 1000w, https://korben.info/app/uploads/2023/06/Copie-de-screenshot-300x151.webp 300w, https://korben.info/app/uploads/2023/06/Copie-de-screenshot-768x386.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Pour vous donner un peu plus envie, voici un aperçu des différentes applications auto-hébergées que vous pouvez installer sur votre serveur. Il y a par exemple <strong>Adguard</strong>, un excellent bloqueur de publicités dont je vous ai déjà parlé, ou <strong>Bazarr</strong>, un gestionnaire de sous-titres pour les films et séries. Et bien sûr pour les développeurs, il existe même une interface Web pour Visual Studio Code appelée <strong>Code-Server</strong>. Avec Tipi, les possibilités sont nombreuses.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-260299524\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p><strong>Firefly III</strong> vous permettra par exemple de suivre vos dépenses et vos revenus en un seul endroit, sans partager vos informations financières avec des services tiers. J’ai également trouvé <strong>Gladys Assistant</strong> qui est un assistant personnel qui prend soin de votre vie privée tout en vous aidant à gérer votre domotique.</p>\n\n\n\n<p>D’autres outils incroyables pour la gestion et la synchronisation de fichiers, la gestion de tâches, la surveillance de serveurs, la gestion de médias, et bien plus encore sont également disponibles. Vous y trouverez aussi <strong>WikiJS</strong>, un wiki open source extensible, <strong>Tautulli</strong>, un compagnon pour Plex, et <strong>Resilio</strong>, une solution basée sur P2P pour la synchronisation et le partage de fichiers. </p>\n\n\n\n<p>Pour le tester, il y a également <a href=\"https://demo.runtipi.io/\" target=\"_blank\" rel=\"noopener\">une démo ici</a>. (user : user@runtipi.io / mdp : password)</p>\n\n\n\n<p><a href=\"https://www.runtipi.io/docs/getting-started/installation\" target=\"_blank\" rel=\"noopener\">L’installation est facile</a>. Il vous faudra un Linux du genre Ubuntu 18.04 LTS, Docker et le plugin Docker Compose. Ensuite, pour l’installer, il suffit de récupérer et lancer la dernière version avec la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code><span style=\"font-family: inherit; font-size: inherit;\">curl -L https://setup.runtipi.io | bash</span></code></pre>\n\n\n\n<p>Et voilà ! A vous des tas d’applications auto-hébergées sans prise de tête. Tipi est un projet plutôt exceptionnel qui rend abordable l’auto-hébergement pour le plus grand nombre.</p>\n\n\n\n<p>Je vous encourage à l’essayer par vous-même.

Ce système d’exploitation mise sur l’universalité, en intégrant une tartine d’environnements de bureau, comme GNOME et KDE Plasma ! En outre, cette distribution est basée sur Arch, ce qui permet d’en avoir les avantages, à savoir une expérience fluide et agréable pour les utilisateurs.</p>\n\n\n\n<p>BlendOS se distingue surtout par son caractère immuable, c’est-à-dire qu’il est conçu pour éviter toute modification non désirée du système. Toutefois, contrairement à d’autres systèmes immuables, il permet quand même d’installer des paquets système de manière classique, grâce à un système fonctionnant par couches.

Vous pouvez utiliser apt, dnf-3, pacman et yay depuis le même shell, comme vous le feriez sur leurs distributions respectives (Ubuntu, Fedora et Arch). Cela signifie que vous pouvez installer et utiliser des applications provenant d’Arch, Fedora, Ubuntu avec une facilité déconcertante. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/SCR-20230602-hwga.webp\" alt=\"\" class=\"wp-image-152654\" width=\"538\" height=\"386\" srcset=\"https://korben.info/app/uploads/2023/06/SCR-20230602-hwga.webp 1000w, https://korben.info/app/uploads/2023/06/SCR-20230602-hwga-300x215.webp 300w, https://korben.info/app/uploads/2023/06/SCR-20230602-hwga-768x551.webp 768w\" sizes=\"(max-width: 538px) 100vw, 538px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1761364503\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>De plus, blendOS prend en charge les applications Android. Vous pouvez ainsi installer vos applications favorites depuis des stores comme F-Droid et Aurora Store, pour les utiliser comme si elles étaient des applications Linux natives, avec un support GPU NVIDIA inclus. Ça simplifiera la vie des développeurs d’applications Android, qui pourront tester facilement leurs applications dans Android Studio comme si c’était des applications Linux natives.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/06/android-apps.1fca9db1_1n6bLA.webp\" alt=\"\" class=\"wp-image-152655\" width=\"688\" height=\"386\" srcset=\"https://korben.info/app/uploads/2023/06/android-apps.1fca9db1_1n6bLA.webp 1000w, https://korben.info/app/uploads/2023/06/android-apps.1fca9db1_1n6bLA-300x169.webp 300w, https://korben.info/app/uploads/2023/06/android-apps.1fca9db1_1n6bLA-768x432.webp 768w\" sizes=\"(max-width: 688px) 100vw, 688px\" /></figure></div>\n\n\n<p>BlendOS permet également d’installer et utiliser des applications Web comme si c’était des applications desktop. Cerise sur le gâteau : vous pouvez même soumettre vos propres applications sur le web store de blendOS et personnaliser votre environnement de bureau selon vos préférences.</p>\n\n\n\n<p>Pour résumer, blendOS est un système d’exploitation vraiment universel qui vous permet d’accéder à des applications et des environnements de bureau provenant de différentes distributions tout en ayant l’assurance que le système ne souffrira de rien grâce à son système immuable.</p>\n\n\n\n<p>Bref, c’est le turfu et <a href=\"https://blendos.co/\" target=\"_blank\" rel=\"noopener\">c’est téléchargeable ici</a>.</p>\n",

C’est une version améliorée de xsv, un utilitaire populaire pour la manipulation de fichiers CSV, qui permet d’analyser, traiter et manipuler des fichiers CSV ultra-rapidement en ligne de commade. En plus de toutes les commandes dispo (+ de 33 commandes), qsv est capable de fonctionner en multithread ce qui permet notamment d’accélérer le traitement des fichiers volumineux !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-514285681\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>En bref, ces commandes vous offrent une multitude de fonctionnalités pour manipuler, transformer et analyser vos fichiers CSV de manière efficace et précise. Quel que soit votre besoin, il y a probablement une commande qui peut vous aider à accomplir votre tâche.</p>\n\n\n\n<p>Voici quelques une de ces commandes : </p>\n\n\n\n<ul>\n<li><strong>apply</strong> : Applique une série de transformations (chaînes de caractères, dates, mathématiques, monnaies, géocodage) à une colonne CSV.</li>\n\n\n\n<li><strong>applydp</strong> : Une version allégée de « apply »</li>\n\n\n\n<li><strong>behead</strong> : Supprime les en-têtes d’un fichier CSV.</li>\n\n\n\n<li><strong>cat</strong> : Concatène les fichiers CSV par ligne ou par colonne.</li>\n\n\n\n<li><strong>count</strong> : Compte le nombre de lignes dans un fichier CSV.</li>\n\n\n\n<li><strong>dedup</strong> : Supprime les lignes en double d’un fichier CSV.</li>\n\n\n\n<li><strong>diff</strong> : Trouve la différence entre deux CSV.</li>\n\n\n\n<li><strong>enum</strong> : Ajoute une nouvelle colonne en numérotant les lignes par l’ajout d’une colonne d’identificateurs incrémentiels ou uuid. Peut aussi être utilisé pour copier une colonne ou remplir une nouvelle colonne avec une valeur constante.</li>\n\n\n\n<li><strong>excel</strong> : Exporte une feuille Excel/ODS spécifiée vers un fichier CSV.</li>\n\n\n\n<li><strong>exclude</strong> : Enlève un ensemble de données CSV d’un autre ensemble en se basant sur les colonnes spécifiées.</li>\n\n\n\n<li><strong>explode</strong> : Explose les lignes en plusieurs en scindant une valeur de colonne sur la base du séparateur donné.</li>\n</ul>\n\n\n\n<p>Et il y en a encore bien d’autres comme « fetch » qui récupère les données de services web pour chaque ligne en utilisant HTTP Get, ou « join » qui fait une jointure interne, externe, croisée, anti & semi sur les fichiers CSV.</p>\n\n\n\n<p>L’une des fonctionnalités que j’ai trouvé le plus sympa dans qsv c’est « apply » avec la prise en charge de fonctions de traitement du langage naturel (NLP), qui incluent la reconnaissance des sentiments, la détection de langues, la détection de similarités et la censure des gros mots ^^. Cela ouvre un univers de possibilités pour l’analyse des données textuelles. Imaginez pouvoir extraire le sentiment général des commentaires des clients ou détecter la langue utilisée, tout ça à la volée. C’est génial !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1596759315\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>L’autre aspect que j’apprécie énormément dans qsv est son intégration avec d’autres outils tels que PostgreSQL, SQLite, luau (un langage de script rapide et flexible dérivé de Lua) et Python. Cela signifie que vous pouvez lancer des requêtes ou des scripts pour chaque ligne d’un fichier CSV, voire même effectuer des jointures avec des fichiers de grande taille sans bousiller la mémoire dispo.</p>\n\n\n\n<p>Pour vous donner un exemple de la puissance de qsv, imaginez que vous avez deux fichiers CSV avec 1 million de lignes et 9 colonnes chacun que vous devez comparer. Avec qsv, cette tâche peut être accomplie en moins de 600 ms ! Excel serait sans doute très lent dans la même situation et risquerait même de planter comme une grosse daube.</p>\n\n\n\n<p>Bref, avec qsv, c’est des temps de traitement plus courts, et la possibilité d’effectuer des tâches complexes en un clin d’œil. </p>\n\n\n\n<p>Pour l’essayer vous-même, vous pouvez le <a href=\"https://github.com/jqnatividad/qsv\" target=\"_blank\" rel=\"noopener\">télécharger à partir de GitHub</a>, où vous trouverez également une documentation complète.</p>\n",

De plus, ChatALL est compatible avec Windows, macOS et Linux.</p>\n\n\n\n<p>Alors, comment utiliser ChatALL ?

Ce logiciel simplifie le processus de récupération des mises à jour de la plateforme de mise à jour unifiée de Microsoft, et vous permet de créer un support d’installation de celles-ci depuis Windows, macOS ou encore Linux. C’est un véritable allié pour tous ceux qui souhaitent profiter d’une mise à jour constante de leur système d’exploitation Windows, peu importe sa version (finale, dev…etc) ou qui ont besoin de faire des supports d’installation à jour.</p>\n\n\n\n<p>L’outil inclus 2 utilitaires : UUPDownload et UUP Media Converter. Le premier outil, <strong>UUPDownload</strong>, permet tout simplement de scanner, récupérer et télécharger les mises à jour de UUP de toutes les versions de Windows (Desktop, Windows 10X, Windows Holographic, Windows Server, Windows Mobile, Windows IoT etc…).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"595\" src=\"https://korben.info/app/uploads/2023/06/msuupdate.webp\" alt=\"\" class=\"wp-image-152635\" srcset=\"https://korben.info/app/uploads/2023/06/msuupdate.webp 1000w, https://korben.info/app/uploads/2023/06/msuupdate-300x179.webp 300w, https://korben.info/app/uploads/2023/06/msuupdate-768x457.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Et le second, <strong>UUPMediaConverter</strong> permet de convertir les fichiers UUP en ISO pour toutes les éditions de Windows. L’image ISO ainsi créée est parfaitement bootable.</p>\n\n\n\n<p>L’utilisation de UUP Media Creator se fait en ligne de commande mais si vous aimez les interfaces utilisateur, une version avec interface est également disponible sur le Microsoft Store. Il est à noter, cependant, qu’elle ne prend pas encore en charge la dernière version du projet.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1651527978\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>UUP Media Creator s’avère donc être un outil extrêmement précieux pour quiconque souhaite maintenir à jour différentes versions de Windows sans passer par les outils de Microsoft.</p>\n\n\n\n<p><a href=\"https://github.com/gus33000/UUPMediaCreator\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Ça se profile bien ? Voilà déjà presque 1 an que je suis partenaire d’<a href=\"https://korben.info/incogni-test.html\" data-type=\"link\" data-id=\"https://korben.info/incogni-test.html\">Incogni</a>. Et je trouvais que ça valait la peine de faire un petit coup d’oeil dans le rétroviseur pour voir comment les choses ont avancé depuis mon test de l’époque.</p>\n\n\n\n<p><strong>La mission d’Incogni reste inchangée</strong>. Elle est toujours de vous permettre de reprendre la main sur les informations personnelles qui circulent à votre propos (et à votre insu) sur le web. Tout ce que vous avez offert aux différents services que vous utilisez (réseaux sociaux, boutiques en ligne, parfois sites officiels) a potentiellement fuité, été hacké et/ou a été récupéré dans des bases de données. Bases qui sont ensuite vendues à ce que l’on appelle des data brokers qui vont en croiser plusieurs pour obtenir un profil le plus précis possible de chaque internaute.</p>\n\n\n\n<p>Déjà j’espère qu’à force vous avez compris ce que sont les data brokers et comment ils utilisent vos informations pour s’engraisser sur votre dos. J’en ai fait plusieurs articles, <a href=\"https://korben.info/data-brokers-incogni.html\" data-type=\"link\" data-id=\"https://korben.info/data-brokers-incogni.html\">par exemple ici</a> ou <a href=\"https://korben.info/risques-lies-aux-data-brokers.html\" data-type=\"link\" data-id=\"https://korben.info/risques-lies-aux-data-brokers.html\">encore là</a>.</p>\n\n\n\n<p>Nous avons souvent l’impression de ne pas être concernés, mais combien de mails ou de SMS non voulus recevez-vous chaque jour ? De coup de fil ou SMS inopinés ? On ne s’en rend pas forcément compte parce que (et heureusement) les filtres antispam fonctionnent plutôt bien chez la plupart des fournisseurs, mais cela n’empêche pas que ces gens ont nos infos.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"450\" height=\"278\" src=\"https://kbn.im/3KItIa9\" alt=\"\"/></figure></div>\n\n\n<p>Adresse mail, numéro de téléphone, nom et prénom, voire parfois adresses physiques et/ou lieux ou vous aimez vous balader, choses que vous aimez faire, historique de navigation, etc. Vous voyez tout de suite pourquoi c’est problématique. Rien à cacher, mais pas forcément envie non plus que tout le monde soit au courant, surtout si derrière c’est juste pour nous faire bouffer des campagnes de spam marketing.</p>\n\n\n\n<p>Bref <a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Incogni n’a pas commencé à dévier de son objectif</a> et nous proposer des tas d’options diverses un peu fourre-tout. Ils sont restés concentrés sur leur service de base et l’on amélioré au fil des mois et des retours d’expériences. Notamment concernant le nombre de data brokers qu’ils surveillent, 146 l’an dernier pour plus de 180 aujourd’hui. Ils ont aussi continué à prodiguer de nombreux bons conseils sur le respect de la vie privée, la sécurité en ligne … via <a href=\"https://blog.incogni.com/\" data-type=\"link\" data-id=\"https://blog.incogni.com/\" target=\"_blank\" rel=\"noreferrer noopener\">leur blog</a> (n’hésitez pas à le lire il y a de très bonnes choses).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"800\" height=\"426\" src=\"https://korben.info/app/uploads/2022/09/incogni-donnees.jpg\" alt=\"\" class=\"wp-image-130593\" srcset=\"https://korben.info/app/uploads/2022/09/incogni-donnees.jpg 800w, https://korben.info/app/uploads/2022/09/incogni-donnees-300x160.jpg 300w, https://korben.info/app/uploads/2022/09/incogni-donnees-768x409.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" /></figure></div>\n\n\n<p>Le service continue de rester simple et épuré,<strong> vous n’avez qu’une étape à gérer </strong>et ils s’occupent du reste ! Vous créez un compte, vous choisissez les informations que à faire disparaitre, vous leur déléguez le droit de prendre contact avec les brokers en votre nom … et c’est tout ! L’interface reste simple à prendre en main et vous pourrez y suivre l’avancée du process en 1 coup d’oeil.</p>\n\n\n\n<p>Eux vont ensuite scanner les quasi 200 courtiers de leur stock et les contacter 1 à 1 si ces derniers ont des choses vous concernant. Incogni leur met un peu la pression en usant les lois et les peines applicables là où sont situés les brokers (RGPD en Europe, CCPA aux USA, etc.) dans le cas d’un refus de leur part. La plupart des vautours auront supprimé les éléments dans les 2 mois. Après, un suivit régulier est effectué par le service pour s’assurer que vos infos ne sont pas de nouveau ajoutées quelques semaine/mois plus tard. Et cela tant que vous continuerez à payer le service (6.5$/mois) forcément.</p>\n\n\n\n<p>Il faut savoir que vous pouvez faire cela par vous-mêmes … pour autant que vous trouviez au moins le mail des courtiers à contacter (ce qui n’est pas toujours simple). Et même si c’est le cas, cela reste pas mal chronophage et vous avez sans doute mieux à faire dans la vie (comme regarder pour la 8e fois Stargate SG-1 de A à Z). Incogni annonce sauver plus de 300 heures de votre temps, je vous avoue que je n’ai pas testé donc je les prends au mot pour cette stat 😉</p>\n\n\n\n<h4 class=\"wp-block-heading\">Et mon test justement, qu’est ce qu’il est devenu ?</h4>\n\n\n\n<p>L’outil avait trouvé 90 brokers qui détenaient mes infos et 18 m’avaient effacé au bout de seulement 4-5 jours. J’ai ensuite laissé les choses suivre leur cours sans trop y revenir et aujourd’hui 67 ont répondu positivement. Entre-temps Incogni a trouvé 3 brokers supplémentaires (donc 93 au total) et seulement 26 sont encore réfractaires. Environ 72% des courtiers ont donc fait ce qu’il fallait.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"315\" src=\"https://korben.info/app/uploads/2023/08/test-resultats.jpg\" alt=\"Résultats du test\" class=\"wp-image-153610\" srcset=\"https://korben.info/app/uploads/2023/08/test-resultats.jpg 1000w, https://korben.info/app/uploads/2023/08/test-resultats-300x95.jpg 300w, https://korben.info/app/uploads/2023/08/test-resultats-768x242.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Et, rayon nouveauté, nous avons maintenant droit à une liste des suppressions « par défaut » (à droite sur l’image, <em>suppression list entries</em>). Il s’agit du nombre de<strong> data brokers qui ne collecteront, n’échangeront ni ne stockeront plus d’informations vous concernant</strong>. Vous avez même un log avec le nom des organismes, la date de leur action, etc. </p>\n\n\n\n<p>Franchement c’est bien foutu, on peut du coup suivre qui tente de vous rajouter au bout de quelques mois. Avec toujours la vue détaillée qui permet de situer chaque broker selon son niveau de risques, comment il utilise nos infos, le nombre de requêtes déjà envoyées, le temps de résolution, etc. La seule chose qui manque c’est p-e les informations que chaque broker détient sur nous (si c’est juste le mail ou d’autres choses).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"185\" src=\"https://korben.info/app/uploads/2023/08/liste-data-brokers.jpg\" alt=\"Liste des data brokers\" class=\"wp-image-153609\" srcset=\"https://korben.info/app/uploads/2023/08/liste-data-brokers.jpg 1000w, https://korben.info/app/uploads/2023/08/liste-data-brokers-300x56.jpg 300w, https://korben.info/app/uploads/2023/08/liste-data-brokers-768x142.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Même si c’est forcément sur les premières semaines que vous verrez le plus d’activité, le rythme de croisière actuel semble être de 5 à 10 retraits par mois, ce n’est pas négligeable.</p>\n\n\n\n<p>Depuis mon test la plupart des sites tech d’importance ont parlé du service de Surfshark. Cela va de Cybernews à PC Mag, Techradar ou plus proche de nous Next Inpact, Frandroid, Mac G & Co. Et les retours sont généralement plutôt bon. Que ce soit pour le service ou son prix (dans la moyenne basse du marché). Idem pour les particuliers qui lui donnent 4.2/5 sur Trustpilot.</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Il ne vous reste plus qu’à découvrir Incogni !</a></h2>\n",

C’est un outil qui vous permettra d’automatiser le processus de réduction en taille de Windows, en utilisant uniquement des utilitaires Microsoft tels que DISM (donc sans aucun outil externe).</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1969660540\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Comme ça vous pourrez créer votre propre version à vous de <a href=\"https://archive.org/details/tiny-11-NTDEV\" target=\"_blank\" rel=\"noopener\"><strong>Tiny11</strong></a>.</p>\n\n\n\n<p>Le seul exécutable inclus dans cet outil s’appelle oscdimg.exe, et il est fourni avec le ADK de Windows (Kit d’évaluation et de déploiement). Il sera utilisé pour créer les images ISO bootables. </p>\n\n\n\n<p>Le script est capable de contourner l’obligation d’avoir un compte Microsoft lors de la phase OOBE et ainsi de déployer l’image avec l’option /compact. Vous pouvez être assuré que tout est open source, ce qui fait que vous êtes libre de personnaliser, ajouter ou supprimer tout ce que bon vous semble. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"638\" src=\"https://korben.info/app/uploads/2023/06/Screenshot_20230203-100010_YouTube-2-1024x638.jpg\" alt=\"\" class=\"wp-image-152630\" srcset=\"https://korben.info/app/uploads/2023/06/Screenshot_20230203-100010_YouTube-2-1024x638.jpg 1024w, https://korben.info/app/uploads/2023/06/Screenshot_20230203-100010_YouTube-2-300x187.jpg 300w, https://korben.info/app/uploads/2023/06/Screenshot_20230203-100010_YouTube-2-768x478.jpg 768w, https://korben.info/app/uploads/2023/06/Screenshot_20230203-100010_YouTube-2-1536x957.jpg 1536w, https://korben.info/app/uploads/2023/06/Screenshot_20230203-100010_YouTube-2.jpg 1727w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Ce script est quelque peu « rigide » si je peux dire, puisque seules les versions de build spécifiées peuvent être modifiées. De plus, seule la version en-us x64 de Windows 11 est prise en charge pour le moment. Cependant, l’utilisateur final peut facilement corriger cela en remplaçant chaque instance de « en-us » par la langue nécessaire (comme fr-FR, etc.) et chaque instance de x64 par arm64. Les versions compatibles de Windows 11 incluent actuellement les builds 22621.525, 22621.1265 et 25300.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-170420272\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Voici comment l’utiliser : <a href=\"https://www.microsoft.com/software-download/windows11\" target=\"_blank\" rel=\"noopener\">Téléchargez l’image ISO de Windows 11</a>, montez-la avec l’Explorateur Windows et exécutez le script en tant qu’administrateur.

Mais ce ne sont pas de gros soucis.</p>\n\n\n\n<p>Bref, c’est une excellente solution pour créer rapidement une version allégée de Windows 11 sans avoir à vous soucier d’éliminer à la main des applications ou fonctionnalités.</p>\n\n\n\n<p><a href=\"https://github.com/ntdevlabs/tiny11builder\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

L’interface est agréable et permet de découvrir de nouveaux sujets en faisant simplement défiler les thèmes exactement comme sur Instagram ou TikTok.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https://korben.info/app/uploads/2023/06/IMG_0787-473x1024.webp\" alt=\"\" class=\"wp-image-152620\" width=\"-281\" height=\"-608\" srcset=\"https://korben.info/app/uploads/2023/06/IMG_0787-473x1024.webp 473w, https://korben.info/app/uploads/2023/06/IMG_0787-139x300.webp 139w, https://korben.info/app/uploads/2023/06/IMG_0787-768x1662.webp 768w, https://korben.info/app/uploads/2023/06/IMG_0787-710x1536.webp 710w, https://korben.info/app/uploads/2023/06/IMG_0787-946x2048.webp 946w, https://korben.info/app/uploads/2023/06/IMG_0787-scaled.webp 1183w\" sizes=\"(max-width: 473px) 100vw, 473px\" /></figure></div>\n\n\n<p>L’idée derrière Swen, c’est de combiner les codes visuels des réseaux sociaux avec des contenus de qualité provenant de nombreux partenariats avec des médias établis. Une des fonctionnalités intéressantes de Swen, c’est la possibilité de réagir aux actualités avec des vidéos de 10 secondes. Les utilisateurs peuvent ainsi partager leur opinion de manière rapide et dynamique, tout en invitant leurs amis à rejoindre leur communauté. C’est excellent moyen de créer des discussions autour des sujets qui nous tiennent à cœur un peu comme sur Twitter mais en vidéo.</p>\n\n\n\n<p>Pour vous donner un exemple concret, imaginez que vous êtes en train de consulter votre fil d’actualité. Vous tombez sur un article qui traite des dernières magouilles d’un parti politique français. Et là, paf, ça vous énerve ! Donc vous pouvez prendre votre téléphone, enregistrer une réaction en vidéo de 10 secondes où vous exprimez votre opinion voire un râââle animal de contestation et l’envoyer à votre communauté. Vos amis pourront alors visionner votre vidéo et réagir à leur tour, créant ainsi un véritable échange qui vous mènera sans aucun doute au point Godwin.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https://korben.info/app/uploads/2023/06/IMG_0788-473x1024.webp\" alt=\"\" class=\"wp-image-152622\" width=\"-309\" height=\"-668\" srcset=\"https://korben.info/app/uploads/2023/06/IMG_0788-473x1024.webp 473w, https://korben.info/app/uploads/2023/06/IMG_0788-139x300.webp 139w, https://korben.info/app/uploads/2023/06/IMG_0788-768x1662.webp 768w, https://korben.info/app/uploads/2023/06/IMG_0788-710x1536.webp 710w, https://korben.info/app/uploads/2023/06/IMG_0788-946x2048.webp 946w, https://korben.info/app/uploads/2023/06/IMG_0788-scaled.webp 1183w\" sizes=\"(max-width: 473px) 100vw, 473px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1260215945\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>De plus, Swen propose des ressources et tutoriels clairs pour aider les utilisateurs à mieux comprendre les sujets abordés. Par exemple, si vous souhaitez en savoir plus sur les enjeux environnementaux, l’application vous proposera des articles détaillés, des vidéos explicatives et des liens vers d’autres ressources pertinentes. De cette manière, vous pourrez approfondir votre connaissance sur le sujet et mieux appréhender les différents points de vue.</p>\n\n\n\n<p>Vous pouvez télécharger la <a href=\"https://apps.apple.com/app/apple-store/id1621510925?pt=124946287&ct=Landing+Page&mt=8\" target=\"_blank\" rel=\"noopener\">version iOS</a> ici et la version Android arrive bientôt. Déso pas déso.</p>\n\n\n\n<p>Bref, pour conclure, Swen est une véritable alternative aux réseaux sociaux et aux sites traditionnels pour s’informer de manière « relativement » fiable et diversifiée, tout en offrant une expérience utilisateur dans l’air du temps. </p>\n\n\n\n<p>N’hésitez pas à jeter un œil à l’application </p>\n\n\n\n<p><a href=\"https://www.swen.media/\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a>.</p>\n",

L’idée c’est de fournir aux LLM (en particulier GPT-3.5 et GPT-4) la capacité d’accomplir des tâches complexes sans intervention de l’utilisateur en les décomposant en problèmes plus petits et en collectant des informations à l’aide d’Internet et d’autres sources externes.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1191958270\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Comme vous êtes des passionnés de technologie, je suis certain que ça va vous plaire.</p>\n\n\n\n<p>Alors comment installer et exécuter SmartGPT ? </p>\n\n\n\n<p>Avant tout, installez cargo, de préférence la dernière version stable. Puis clonez le dépôt avec </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/Cormanz/smartgpt.git && cd smartgpt</code></pre>\n\n\n\n<p>Enfin, exécutez-le en mode release avec </p>\n\n\n\n<pre class=\"wp-block-code\"><code>cargo run --release</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2067067701\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Cela créera un config.yml que vous n’aurez alors plus qu’à modifier pour y mettre votre clé API. Ajustez évidemment la configuration à votre goût, puis relancez la commande cargo run.</p>\n\n\n\n<p>Vous serez vous aussi prêt à explorer les merveilles du monde des LLM !</p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls src=\"https://user-images.githubusercontent.com/32941017/241816662-11d737b4-9c93-4f22-b84f-d9c9d1ee0f9c.mp4\"></video></figure>\n\n\n\n<p>SmartGPT fonctionne avec des <strong>Autos</strong> et des<strong> Agents</strong>. Ce concept peut être comparé à une entreprise où les managers (Autos) supervisent des équipes d’employés, appelés ici « agents », en répartissant les tâches pour accomplir un projet complexe. Chaque agent a sa propre mémoire à long terme et sauvegarde les informations dedans. L’agent du SmartGPT apprend et retient ainsi constamment de nouvelles choses pour accomplir ses missions.</p>\n\n\n\n<p>Pour citer Isaac Newton: « <em>Si j’ai vu plus loin que les autres, c’est en me tenant sur les épaules de géants</em>« . SmartGPT, c’est un peu la même chose : en utilisant les connaissances et les compétences acquises grâce aux recherches précédentes, il étend l’horizon de ce qui est possible de faire avec les LLM.</p>\n\n\n\n<p>En plus des Autos et des Agents, SmartGPT utilise également un mécanisme de plugins pour ajouter des fonctionnalités supplémentaires telles que la recherche sur Google et la navigation sur le Web.</p>\n\n\n\n<p>Mais même les projets les plus prometteurs ont leurs défis à relever. Les deux obstacles majeurs pour SmartGPT sont un écosystème moins développé que celui d’AutoGPT et une gestion de la mémoire encore un peu limitée. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1975737099\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>SmartGPT est disponible sous la licence MIT. </p>\n\n\n\n<p>Et n’hésitez pas à partager vos découvertes et vos idées avec la communauté du projet (y’a un Discord).</p>\n\n\n\n<p><a href=\"https://github.com/Cormanz/smartgpt\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

En gros, s5cmd va vous permettre de maîtriser l’ensemble de votre univers de stockage d’objets chez sans effort.</p>\n\n\n\n<p>Mais alors, qu’est-ce qui rend s5cmd si rapide? La réponse réside principalement dans deux éléments: le langage de programmation utilisé qui est le Go et la parallélisation des tâches.

Car oui, vous le savez, on peut utiliser la RAM de son PC comme espace de stockage (<a href=\"https://korben.info/monter-tmpfs-linux.html\">ramdisk</a>). Mais on peut aller encore plus loin en utilisant la mémoire de notre carte graphique. C’est là où <strong>GpuRamDrive</strong> entre en scène !</p>\n\n\n\n<p>Il s’agit d’un logiciel open source qui nous permet d’utiliser la mémoire libre de notre carte graphique comme une extension de la RAM de votre ordinateur pour en faire un disque de stockage virtuel. Niveau perf, c’est comme passer d’un vélo à une moto. Je me devais donc de partager cette trouvaille avec vous.</p>\n\n\n\n<p>Mais avant d’aller plus loin, laissez-moi vous donner un peu de contexte sur cette technologie. Savez-vous ce que signifie le terme GPU ? Il s’agit de l’unité de traitement graphique, <strong>Graphics Processing Unit</strong> en anglais. Les GPUs sont des processeurs puissants qui sont spécialement conçus pour accélérer les graphiques et les calculs complexes. Ils sont généralement plus rapides que les processeurs traditionnels et disposent de leur propre mémoire, appelée mémoire vidéo (VRAM).</p>\n\n\n\n<p>Par conséquent, l’idée de GpuRamDrive est simplement de tirer profit de cette puissance <a href=\"https://korben.info/utilisez-la-memoire-de-votre-carte-graphique-comme-ramdisk-pour-du-swap.html\">en réquisitionnant une partie de la mémoire vidéo pour en faire un espace de stockage</a>. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-147708439\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Alors, comment fait-on ?</p>\n\n\n\n<p>Pour commencer, je vous recommande de vérifier combien de mémoire VRAM votre carte graphique possède. Vous pouvez faire cela en ouvrant le <strong>Gestionnaire des tâches</strong> de Windows (Ctrl + Shift + Esc), puis en cliquant sur l’onglet « Performances », et en choisissant « GPU ». Notez votre valeur de « Mémoire dédiée » – c’est la VRAM disponible.</p>\n\n\n\n<p>Maintenant que l’on sait combien de mémoire nous avons à disposition, il est temps d’installer GpuRamDrive. </p>\n\n\n\n<p>Téléchargez le fichier zip de GpuRamDrive à partir de <a href=\"https://github.com/prsyahmi/GpuRamDrive/releases\" target=\"_blank\" rel=\"noopener\">GitHub</a>, puis créez et formatez un disque RAM, en spécifiant la quantité de mémoire à utiliser, ainsi que le système de fichiers et le nom du volume.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/05/59966600-3285-11eb-94aa-9c2c917da458.webp\" alt=\"\" class=\"wp-image-152562\" width=\"626\" height=\"514\" srcset=\"https://korben.info/app/uploads/2023/05/59966600-3285-11eb-94aa-9c2c917da458.webp 913w, https://korben.info/app/uploads/2023/05/59966600-3285-11eb-94aa-9c2c917da458-300x246.webp 300w, https://korben.info/app/uploads/2023/05/59966600-3285-11eb-94aa-9c2c917da458-768x631.webp 768w\" sizes=\"(max-width: 626px) 100vw, 626px\" /></figure></div>\n\n\n<p>Et voilà, vous avez maintenant un disque RAM basé sur la mémoire de votre GPU ! Vous pouvez l’utiliser comme n’importe quel autre disque. Vous pouvez y déplacer les fichiers et les applications que vous utilisez fréquemment pour profiter de vitesses de lecture et d’écriture améliorées, et ainsi redonner du mordant à votre machine.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"709\" src=\"https://korben.info/app/uploads/2023/05/65470470-b37a-11e6-908d-e08687a757d3-1.webp\" alt=\"\" class=\"wp-image-152563\" srcset=\"https://korben.info/app/uploads/2023/05/65470470-b37a-11e6-908d-e08687a757d3-1.webp 1000w, https://korben.info/app/uploads/2023/05/65470470-b37a-11e6-908d-e08687a757d3-1-300x213.webp 300w, https://korben.info/app/uploads/2023/05/65470470-b37a-11e6-908d-e08687a757d3-1-768x545.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Cependant, il est important de noter que la mémoire RAM est volatile, ce qui signifie que les données seront perdues en cas de coupure d’alimentation ou de redémarrage de l’ordinateur. Donc, veillez à sauvegarder régulièrement vos données importantes sur un autre disque.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-694319990\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>En somme, GpuRamDrive est un excellent moyen d’exploiter la mémoire vidéo disponible de votre carte graphique pour booster les performances de votre ordinateur. C’est un outil puissant qui peut vous aider à tirer le meilleur parti de votre matériel et vous pouvez en savoir plus <a href=\"https://github.com/prsyahmi/GpuRamDrive\" target=\"_blank\" rel=\"noopener\">en cliquant ici !</a></p>\n",

Parce que dès septembre ça redémarre fort avec la rentrée scolaire, etc. Mais en attendant, reposons-nous les doigts pieds en éventail et parlons de notre sécurité en ligne avec l’antivirus de Surfshark.</p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Offre promotionnelle du moment : activez Surfshark antivirus pour 3.49€/mois, soit 76% d’économies sur l’abonnement 1 an !</a></div>\n</div>\n\n\n\n<p>Si vous suivez ce site depuis ses débuts (il y a presque 20 ans), vous savez que j’ai souvent parlé des différentes menaces qui apparaissaient sur la toile. D’ailleurs je me suis prêté à un petit exercice que seuls les vieux peuvent se permettre de faire sur leur propre site : j’ai fouillé dans <a href=\"https://korben.info/category/infos/securite\" data-type=\"URL\" data-id=\"https://korben.info/category/infos/securite\">mes archives sécu</a> pour voir un peu comment la sécurité à évoluée entre 2004 et aujourd’hui.</p>\n\n\n\n<p>Certaines menaces ont bien sûr disparu, d’autres ont vu le jour et certaines existent toujours malgré les années. On va faire le tour de tout ça et voir comment Surfshark vous permet de vous en protéger. Non seulement avec son antivirus, mais aussi avec le reste de suite de services comme <a href=\"https://korben.info/partez-en-vacances-avec-surfshark-vpn.html\" data-type=\"URL\" data-id=\"https://korben.info/partez-en-vacances-avec-surfshark-vpn.html\">son VPN</a> (dont je vous parle régulièrement), son système d’alerte, etc.</p>\n\n\n\n<h2 class=\"wp-block-heading\">Malware, logiciels espions & ransomware </h2>\n\n\n\n<p>On va commencer par ce qui reste sans doute l’une des plus grandes familles de menaces à l’heure actuelle. Il est bien loin le temps où vous étiez contaminé via <a href=\"https://korben.info/le-premier-pv-malware-est-arrive.html\" data-type=\"URL\" data-id=\"https://korben.info/le-premier-pv-malware-est-arrive.html\">une fausse contravention</a> reçue afin de vous faire installer un logiciel malveillant (j’avais prévenu, j’ai retrouvé quelques anciennes pépites vintage).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"204\" decoding=\"async\" src=\"https://kbn.im/surfshark-antivirus\" alt=\"\"/></figure></div>\n\n\n<p>L’idée de ces infections est de contaminer votre système via un matériel hardware (genre clé USB), un document ou un téléchargement vérolé, de faire planter votre réseau et/ou de récupérer des données sensibles à votre insu. C’est déjà pénible lorsque ça vous arrive en tant que particulier, mais ça l’est encore plus pour une organisation. Voir c’est carrément dangereux si vous gérez des informations très personnelles ou permettant d’identifier des gens avec une grande précision (documents médicaux, impôts …).</p>\n\n\n\n<p>Les ransomwares (oui en français ont dit rançongiciels, mais … beuuurk) sont un peu comme le stade supérieur des malwares, sorte d’évolution dans Pokémon. Ils vont être capables de chiffrer vos fichiers de manière à ce que vous ne puissiez plus y accéder, puis vous demander une rançon afin de vous débloquer tout ça. Ils visent le plus souvent les entreprises (qui peuvent payer plus), mais pas toujours. Vous vous rappelez de Wannacry il y a 6 ans ? En cause, une faille Windows qui touchait tous les systèmes, incluant les particuliers.</p>\n\n\n\n<h2 class=\"wp-block-heading\">Chevaux de Troie / Trojans</h2>\n\n\n\n<p>Une sous-catégorie de la catégorie précédente, à la différence que l’infection se fait le plus souvent via un logiciel malveillant. Vous téléchargez un outil ressemblant à l’original, mais dans lequel un programme malicieux est incorporé. Vous pensiez gratter quelques euros en récupérant en outil payant de manière gratuite ? Bravo jeunes rebelzzz, vous avez même eu droit un petit bonus gratuit 😉</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"384\" height=\"270\" decoding=\"async\" src=\"https://media.giphy.com/media/l2Sqb9bZGvtTaHWNi/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<h2 class=\"wp-block-heading\">Botnets et DDoS</h2>\n\n\n\n<p>De nombreux appareils connectés à Internet, et non protégés ou ayant téléchargé une application malsaine, ont été contaminés par divers virus au fil des années. Un botnet est une collection de machines ayant été infectées et formant un réseau. Ce réseau peut alors être utilisé pour envoyer des requêtes (et faire tomber des sites) ou des messages par milliers (par exemple des mails de phishing). Dans le cas présent la menace n’est pas directe, mais une protection aurait pu empêcher ces appareils de propager virus et compagnie.</p>\n\n\n\n<h2 class=\"wp-block-heading\">L’hameçonnage aka Phishing</h2>\n\n\n\n<p>Un autre type de menace assez ancienne, mais elle a pris encore plus d’ampleur ces dernières années avec l’arrivée des cryptos. Le domaine est particulièrement ciblé, car certains s’y lancent sans trop savoir ce qu’ils font et sont donc des cibles de choix (non Metamask ne vous contactera jamais, non Trustwallet ne vous demandera jamais votre clé privée …).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"250\" decoding=\"async\" src=\"https://media.giphy.com/media/8eteLyVqRlL1AOz7Uz/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Le but ici est de faire passer pour crédible une communication du site auquel les vilains veulent avoir accès (banques, plateformes crypto/bourse …). Que ce soit en vous balançant un mail ou via une communication sur les réseaux sociaux, souvent avec un certain degré d’urgence (« Cliquez vite sinon votre portefeuille risque d’être bloqué pour toujouuuuurs »). Ou même de vous gruger avec un nom de domaine qui est écrit avec des caractères différents (<a href=\"https://korben.info/se-proteger-contre-attaques-de-phishing-utilisent-noms-de-domaine-dautres-alphabets.html\" data-type=\"URL\" data-id=\"https://korben.info/se-proteger-contre-attaques-de-phishing-utilisent-noms-de-domaine-dautres-alphabets.html\">attaque homographique</a>). Vous cliquez sur le lien envoyé ou vous vous rendez sur le site, vous entrez vos identifiants et boom le piège se referme. </p>\n\n\n\n<h2 class=\"wp-block-heading\">Cryptojacking</h2>\n\n\n\n<p>Le cryptojacking est une menace qui semblait un peu passée de mode après avoir pas mal fait parler d’elle autour de 2018. Il s’agissait de vous faire installer une application quelconque (sur votre navigateur par exemple) qui minait de la crypto (surtout du Monero) à votre insu en arrière-plan. Les principaux navigateurs ont vite réagi, mais il semblerait que la pratique ait continué à progresser avec de nouveaux records en 2022. Il y a quelques mois, on a même trouvé un mineur de crypto caché <a href=\"https://www.bleepingcomputer.com/news/security/pirated-final-cut-pro-infects-your-mac-with-cryptomining-malware/\" data-type=\"URL\" data-id=\"https://www.bleepingcomputer.com/news/security/pirated-final-cut-pro-infects-your-mac-with-cryptomining-malware/\" target=\"_blank\" rel=\"noopener\">dans les versions illégales de Final Cut Pro</a> d’Apple. </p>\n\n\n\n<h2 class=\"wp-block-heading\">Injection dans les pubs / Malvertising</h2>\n\n\n\n<p>Plus récente, cette technique utilise les espaces publicitaires des sites pour injecter du code malveillant. Pour résumer, il s’agit pour les attaquants de compromettre un des serveurs diffusant la publicité et de rediriger le clic sur celle-ci vers leur propre site ou d’installer discrètement un logiciel corrompu (type exploit kit ou autres). Dans certains cas cela peut même se faire sans interaction, juste en visitant une page, via la simple exécution d’un JavaScript ou de Flash (qui se perd heureusement).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://media.giphy.com/media/3o752lstY4OCun1YVq/giphy-downsized-large.gif\" alt=\"\" width=\"360\" height=\"360\"/></figure></div>\n\n\n<h2 class=\"wp-block-heading\">Solution : Surfshark Antivirus</h2>\n\n\n\n<p>La solution pour ne plus entendre parler de ces différentes menaces et vous moquer de ceux qui se font encore avoir ? (se moquer c’est mal, sachez-le). <strong>De bons comportements sur le web et un bon antivirus</strong> comme celui de Surfshark (dispo pour macOS, Android et Windows). Ce dernier, qui utilise le très bon moteur d’Avira, va en effet mettre en place de manière automatisée différentes couches de protection :</p>\n\n\n\n<ul>\n<li>surveillance en temps réel et en continu</li>\n\n\n\n<li>analyses de vos disques durs (manuelles ou programmées à intervalle régulier)</li>\n\n\n\n<li>scan de tous les fichiers que vous téléchargez</li>\n\n\n\n<li>analyse des pièces jointes reçues dans vos mails</li>\n\n\n\n<li>prémunit des attaques Zéro Day (failles connues, mais non encore patchées)</li>\n\n\n\n<li>sécurise la caméra et le micro</li>\n\n\n\n<li>bloque les publicités</li>\n</ul>\n\n\n\n<p>Et tout cela de manière intuitive (interface épurée) et surtout légère pour votre machine, pas besoin d’avoir une grosse bécane pour le faire tourner. Son autre avantage est bien entendu d’être intégré aux autres produits Surfshark, ce qui vous permet de tout gérer à partir de la même interface. En gros, <strong>vous pouvez l’oublier et il fera le nécessaire en tâche de fond</strong>. De plus, par rapport à mon premier article sur le sujet, <a href=\"https://korben.info/surfshark-antivirus.html\" data-type=\"URL\" data-id=\"https://korben.info/surfshark-antivirus.html\">Surfshark Antivirus</a> a pris un peu de bouteille.</p>\n\n\n\n<p>Cerise sur votre glace fondante, Surfshark Antivirus propose en ce moment une <strong>offre promo à -76% sur l’abonnement 1 an</strong> ! Vous ne payerez donc que 3.49€ par mois (HT).</p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768\" target=\"_blank\" rel=\"noopener\">Profitez-en !</a></h2>\n",

Elle va jusqu’à proposer des environnements inspirés de la culture pop, comme des scènes de films ou de jeux vidéo.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Blockade Labs: Sketch-to-Skybox Announcement\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/0ANrBMnoh0Q?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Sky Box a d’ailleurs proposé à Sega de créer gratuitement des lieux pour un futur jeu Sonic en 3D. Ainsi, l’équipe de développement d’un jeu pourrait travailler à partir de propositions visuelles réalistes fournies par l’outil Sky Box, ce qui ouvre un monde de possibilités pour les créateurs de jeux. Même la série à succès <em>The Witcher</em> a eu droit à sa part de concepts générés par l’IA, avec plusieurs lieux imaginés pour une éventuelle suite.</p>\n\n\n\n<p>Mais ce n’est pas tout, car Sky Box est capable d’imaginer des collaborations créatives entre différents univers. Par exemple, elle a généré un biome cubique inspiré des îles Skellige pour une éventuelle collaboration entre CD Projekt RED et <em>Minecraft</em>.

J’y jouais beaucoup sur la NES quand j’étais petit, alors imaginez ma joie lorsque j’ai appris que grâce à <a href=\"https://twitter.com/VEsoterica\" target=\"_blank\" rel=\"noopener\">Video Game Esoterica</a>, il est désormais possible de jouer à un jeu presque introuvable : <em>Castlevania: The Arcade</em> sur PC ! </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1830818793\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Ce trésor perdu du passé est enfin accessible pour tous les amoureux de jeux d’arcade et des aventures de chasseurs de vampires. <em>Castlevania: The Arcade</em> était un jeu de tir au pistolet développé et édité par Konami, sorti en 2009 uniquement sur borne d’arcade. Evidemment, les fans inconditionnels ont cherché désespérément depuis à mettre la main sur une borne d’arcade du jeu. Mais c’est un Graal impossible à atteindre pour le commun des mortels. Mais grâce à ce portage, c’est de l’histoire ancienne. Plus besoin de vendre votre âme au diable pour mettre la main sur une version borne d’arcade tant convoitée !</p>\n\n\n\n<p>Dans ce jeu, les joueurs prennent le rôle de personnages issus de la série et se battent contre des hordes de créatures maléfiques dans des environnements inspirés des Castlevania précédents. Le gameplay est riche et immersif, à tel point qu’on en oublierait presque qu’il s’agit d’un jeu d’arcade et non d’un des épisodes majeurs de la série. Jusqu’à deux joueurs peuvent jouer simultanément, incitant à la coopération et permettant de partager les frissons de l’aventure.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Castlevania: The Arcade - TUTORIAL - Play it RIGHT NOW on your PC\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/MLMpnAYW3mQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Les personnages du jeu comprennent le chasseur de vampires, la tireuse d’élite et la petite sorcière. Chacun d’eux présente ses propres compétences et armes ce qui permet d’apporter de la fraîcheur à chaque partie.</p>\n\n\n\n<p>Des créatures bien connues telles que Dracula et la Mort font également partie de ce jeu et apportent une touche nostalgique, rappelant les heures que nous avons passées à affronter ces boss redoutables, et qui sont en soi un clin d’œil aux fans de longue date. On notera également la qualité graphique et l’ambiance sonore, toujours fidèle à l’esprit Castlevania, riche en références à la grande époque de la franchise.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1925583851\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Alors si vous souhaitez redécouvrir ce classique oublié ou si vous cherchez à affronter les créatures de la nuit au côté d’un ami, je vous conseille vivement de vous pencher sur Castlevania: The Arcade. Le dump de la carte PCB étant désormais disponible, une fois installé, vous aurez enfin la possibilité de jouer sur votre PC, seul ou en coopération. </p>\n\n\n\n<p>Pour ce qui est des optimisations, je dois dire que le jeu tourne remarquablement bien sur PC, et ce même pour des configurations plus modestes. Bien entendu, il ne vous offrira pas une expérience 100% identique à celle de la borne d’arcade d’origine, notamment en ce qui concerne les contrôleurs spécifiques. Toutefois, ce léger compromis vaut largement la peine si cela signifie pouvoir mettre la main sur ce morceau d’histoire vidéoludique et satisfaire vos envies de chasse aux monstres !</p>\n\n\n\n<p>En résumé, <em>Castlevania: The Arcade</em> est un trésor à la fois pour les amateurs de la série Castlevania et les fans de jeux d’arcade en général. Si vous n’êtes pas familier avec la série, c’est également une excellente occasion de vous plonger dans cet univers par le biais d’un gameplay amusant et coopératif. C’est une cette chance de revivre les frissons des jeux d’arcades des années 2000, le cul visé dans un fauteuil de games bien confortable ^^.</p>\n\n\n\n<p>Le temps est venu d’affronter les forces du mal et de libérer le monde des griffes de l’obscurité. À vos fouets, chasseurs de vampires !

Veillez à ce que la taille de votre image ne dépasse pas 600 x 600 pixels, sinon elle sera redimensionnée automatiquement. Et si vous avez un compte premium, vous bénéficierez d’une taille maximale de 1000 x 1000 pixels.</p>\n\n\n\n<p>Une fois votre image téléchargée, il vous suffit de suivre ces 3 étapes pour obtenir un fichier STL à partir de votre fichier JPG ou PNG :</p>\n\n\n\n<ol>\n<li>Définissez les dimensions et les autres options selon vos préférences.</li>\n\n\n\n<li>Cliquez sur le bouton « Convert to STL » pour lancer la conversion.</li>\n\n\n\n<li>Téléchargez votre fichier STL nouvellement créé.</li>\n</ol>\n\n\n\n<p>Le processus de conversion analysera alors chaque pixel de l’image en niveaux de gris et attribuera une hauteur en 3D en fonction de la luminosité.

Plus le pixel est lumineux, plus le monticule est élevé.</p>\n\n\n\n<p>Trois modes sont disponibles lors de la conversion : le mode Standard, le mode Extrude Color, et le mode Extrude.

StyleGAN est un modèle spécialisé dans la génération d’images ultra-réalistes, tandis que CLIP a la capacité de comprendre et d’associer des images et du texte. Ensemble, ils permettent de générer et de manipuler des images en fonction d’une description textuelle.</p>\n\n\n\n<p>Avant de rentrer dans les détails, il y a une démo accessible sur <a href=\"https://replicate.com/orpatashnik/styleclip\" target=\"_blank\" rel=\"noopener\">Replicate</a> ce qui vous permettra de jouer directement avec.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"StyleCLIP: Text-Driven Manipulation of StyleGAN Imagery\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/5icI0NgALnQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Ainsi, avec StyleCLIP, vous pouvez éditer une image donnée ou générer une image complètement aléatoire qui correspond au mieux à la description textuelle que vous aurez saisi.</p>\n\n\n\n<p>Évidemment, si vous avez une machine assez puissante, vous pourrez déployer ça dessus et le faire tourner puisque tous les scripts et les explications techniques sont disponibles sur la page Github. Les scripts d’inférence sont également disponibles pour ceux qui veulent essayer des choses sans rentrer dans dans l’entraînement de l’IA à proprement dit.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"362\" src=\"https://korben.info/app/uploads/2023/05/teaser.webp\" alt=\"\" class=\"wp-image-152535\" srcset=\"https://korben.info/app/uploads/2023/05/teaser.webp 1000w, https://korben.info/app/uploads/2023/05/teaser-300x109.webp 300w, https://korben.info/app/uploads/2023/05/teaser-768x278.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1717861435\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Comme si cela ne suffisait pas, StyleCLIP propose également une interface utilisateur graphique (GUI) pour faciliter encore plus la manipulation d’images.

Ensuite, tapez un texte neutre comme point de départ (« face »), puis modifiez le texte cible pour y inclure l’édition souhaitée, telle que « face with blue eyes ». Vous verrez alors les résultats aussi étonnants que flippants de l’IA à l’œuvre, modifiant l’image en fonction de vos instructions.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"650\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230529-hogr.webp\" alt=\"\" class=\"wp-image-152534\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230529-hogr.webp 1000w, https://korben.info/app/uploads/2023/05/SCR-20230529-hogr-300x195.webp 300w, https://korben.info/app/uploads/2023/05/SCR-20230529-hogr-768x499.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Comme vous pouvez le voir, ce n’est pas encore parfait mais c’est amusant à essayer.

Tout comme <a href=\"https://korben.info/doom-retro-portage-windows.html\">Doom Retro</a>, il est basé sur l’excellent Chocolate Doom, dont la réputation n’est plus à faire. Pour les fans de rétrogaming comme moi, cela signifie une expérience de jeu améliorée, avec un affichage en top résolution, un rendu en écran large pouvant aller jusqu’à 24:9, et certaines limitations du jeu supprimées. Tout cela, bien sûr, sans entacher la compatibilité originale avec Vanilla Doom et Chocolate Doom.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-318380252\" data-NKSYD1CP-trackid=\"124505\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Admirez ce passage en écran large : </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"577\" src=\"https://korben.info/app/uploads/2023/05/widescreen.gif\" alt=\"\" class=\"wp-image-152500\"/></figure></div>\n\n\n<p>Parmi les nombreuses fonctionnalités de Crispy Doom, certaines retiennent particulièrement l’attention. La liberté de mouvement notamment au niveau de l’angle de vue offre une perspective de jeu beaucoup plus immersive. L’ajout de <a href=\"http://www.gameart.eu/publi/dossiers/lexique/reticule-de-visee.html\" target=\"_blank\" rel=\"noopener\">réticules</a> pour faciliter la visée est également une amélioration bienvenue : après tout, quoi de plus naturel, quand on n’est pas chasseur, que de savoir exactement où l’on tire ^^ ?</p>\n\n\n\n<p>Côté interface, je suis ravi de découvrir un HUD minimaliste (HUD, ça veut dire affichage tête haute), qui n’encombre pas l’écran d’infos inutiles. Pour ne rien gâcher, une fonctionnalité de capture d’écran vraiment clean a été ajoutée, permettant de capturer nos exploits sans les encombrer avec les éléments de l’interface.</p>\n\n\n\n<p>Bien sûr, une longue liste d’autres améliorations sont également de la partie, comme les chiffres de la barre d’état qui ont été colorisés, la possibilité de marcher sur ou sous des monstres et des cadavres suspendus (brrr), ou encore l’inclinaison des armes lors du tir pour encore plus de réalisme.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-190116022\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Je vous invite à consulter la liste complète des fonctionnalités <a href=\"https://crispy-doom.org/\" target=\"_blank\" rel=\"noopener\">ici</a>, mais l’un des atouts majeurs de Crispy Doom, selon moi, est sa capacité à offrir toutes ces améliorations sous la forme d’options que vous êtes libres d’activer ou non via le menu « Crispness », en ligne de commande ou grâce à l’outil <em>crispy-doom-setup</em>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/05/menu.gif\" alt=\"\" class=\"wp-image-152501\"/></figure></div>\n\n\n<p>Crispy Doom prend également en charge les fichiers DEHACKED et au format BEX, ce qui élargit considérablement les possibilités de customisation du jeu. </p>\n\n\n\n<p>Vous pouvez télécharger Crispy Doom pour Windows, MacOS ou Linux depuis la <a href=\"https://crispy-doom.org/\" target=\"_blank\" rel=\"noopener\">page de téléchargement officielle</a>. Les fondus de nouveautés pourront également se tourner vers les versions nightly du soft pour avoir les dernières options et corrections.</p>\n\n\n\n<p>Là où Crispy Doom assure graaaave, c’est dans sa documentation bien détaillée et bien bien complète. Impossible de se sentir perdu, avec des explications claires sur les codes de triche, les contrôles, ou encore les paramètres à utiliser en ligne de commande. Notez qu’à part Doom, il existe également des portages pour d’autres jeux comme Crispy Heretic, Crispy Hexen and Crispy Strife pour ceux qui veulent.</p>\n\n\n\n<p>Pour finir, je tiens à saluer le travail de Fabian Greffrath, qui maintient le projet Crispy Doom. Sans lui, cette version améliorée du jeu culte n’aurait pas vu le jour. Si vous avez des bugs ou des problèmes à signaler, vous pourrez le faire via l’<a href=\"https://github.com/fabiangreffrath/crispy-doom/issues\" target=\"_blank\" rel=\"noopener\">Issue Tracker</a> de GitHub. </p>\n\n\n\n<p>Prêts à replonger dans les méandres de Doom ? </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1930725044\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p><a href=\"https://crispy-doom.org/\" target=\"_blank\" rel=\"noopener\">C’est à découvrir par ici</a>.</p>\n",

Aujourd’hui, je partage avec vous cette bibliothèque de reconnaissance faciale vraiment top : <a href=\"https://github.com/ageitgey/face_recognition\" target=\"_blank\" rel=\"noopener\">face_recognition</a>.</p>\n\n\n\n<p>Cette lib repose sur la pointe de la technologie en matière de reconnaissance faciale, notamment grâce à <a rel=\"noopener\" href=\"http://dlib.net/\" target=\"_blank\">dlib</a>. D’ailleurs, elle revendique une précision impressionnante de 99,38 % au benchmark <a rel=\"noopener\" href=\"http://vis-www.cs.umass.edu/lfw/\" target=\"_blank\">Labeled Faces in the Wild</a>.</p>\n\n\n\n<p>La bibliothèque face_recognition offre une panoplie de fonctionnalités : Elle détecte les faces sur les photos, repère les traits du visage (yeux, nez, bouche et menton) et reconnaît les personnes. Vous pouvez même combiner cette bibliothèque avec d’autres libs Python pour effectuer une reconnaissance faciale en temps réel.</p>\n\n\n\n<p>Pour l’installer, assurez-vous d’avoir Python 3.3+ ou Python 2.7, ainsi que macOS ou Linux. Ensuite, un simple </p>\n\n\n\n<pre class=\"wp-block-code\"><code>pip3 install face_recognition</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-889917746\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>… fera l’affaire ! </p>\n\n\n\n<p>La bibliothèque est également compatible avec <a href=\"https://github.com/ageitgey/face_recognition#deployment\" target=\"_blank\" rel=\"noopener\">Docker</a>, et, si vous rencontrez des problèmes d’installation, <a href=\"https://medium.com/@ageitgey/try-deep-learning-in-python-now-with-a-fully-pre-configured-vm-1d97d4c3e9b\" target=\"_blank\" rel=\"noopener\">une machine virtuelle préconfigurée</a> est à votre disposition. De plus, des instructions d’installation pour Windows, Rasberry Pi et FreeBSD sont également dispo sur la page Github.</p>\n\n\n\n<p>La bibliothèque face_recognition contient deux programmes en ligne de commande : <code>face_recognition</code> et <code>face_detection</code>. </p>\n\n\n\n<p>Le premier programme reconnaît les visages dans une ou plusieurs photos, tandis que le second trouve les positions des visages dans les images. Petite astuce, si vous obtenez plusieurs correspondances pour une même personne, essayez d’ajuster l’option <code>--tolerance</code> pour obtenir des résultats plus précis.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230524-jrjs.webp\" alt=\"\" class=\"wp-image-152481\" width=\"482\" height=\"417\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230524-jrjs.webp 865w, https://korben.info/app/uploads/2023/05/SCR-20230524-jrjs-300x260.webp 300w, https://korben.info/app/uploads/2023/05/SCR-20230524-jrjs-768x666.webp 768w\" sizes=\"(max-width: 482px) 100vw, 482px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230524-jrky.webp\" alt=\"\" class=\"wp-image-152482\" width=\"475\" height=\"409\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230524-jrky.webp 869w, https://korben.info/app/uploads/2023/05/SCR-20230524-jrky-300x259.webp 300w, https://korben.info/app/uploads/2023/05/SCR-20230524-jrky-768x663.webp 768w\" sizes=\"(max-width: 475px) 100vw, 475px\" /></figure></div>\n\n\n<p>Pour essayer le modèle de détection de visage basé sur l’apprentissage en profondeur, je vous invite à implémenter <a rel=\"noopener\" href=\"https://github.com/ageitgey/face_recognition/blob/master/examples/find_faces_in_picture_cnn.py\" target=\"_blank\">ce code</a>.

Comme d’habitude, PyInstaller est votre meilleur ami ! Cependant, une configuration personnalisée sera nécessaire pour fonctionner correctement avec cette bibliothèque.</p>\n\n\n\n<p>Il est bon de noter que cette technologie présente certaines limitations. Par exemple, la reconnaissance faciale fonctionne moins bien sur les enfants et peut varier entre les groupes ethniques. Pour plus de détails, vous pouvez consulter la <a rel=\"noopener\" href=\"https://github.com/ageitgey/face_recognition/wiki/Face-Recognition-Accuracy-Problems#question-face-recognition-works-well-with-european-individuals-but-overall-accuracy-is-lower-with-asian-individuals\" target=\"_blank\">page wiki</a> qui vous expliquera tout à ce sujet.</p>\n\n\n\n<p>En somme, face_recognition est une bibliothèque open-source vraiment chouette permettant le développement de projets de reconnaissance faciale en Python. C’est une bonne opportunité pour vous lancer dans la création d’applications IA de reconnaissance faciale. </p>\n\n\n\n<p><a rel=\"noopener\" href=\"https://github.com/ageitgey/face_recognition\" target=\"_blank\">À découvrir ici</a></p>\n",

Techniquement, c’est donc une « machine virtuelle » avec des pilotes de périphériques custom. Il peut ainsi faire tourner OS X de la version 10.1 à 10.2 ou Mac OS de la version 7.5.2 à la version 9.2.2.</p>\n\n\n\n<p>MOL ne fonctionne pas non plus comme ce bon vieux Wine sur x86. Wine est une implémentation de l’API Win32 (c’est-à-dire que vous n’avez pas besoin de Windows pour exécuter Wine), alors que MOL est une « machine virtuelle » qui vous permet théoriquement de démarrer n’importe quel système d’exploitation PowerPC au sein de MOL.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2023/05/pic12.webp\" alt=\"\" class=\"wp-image-152476\" srcset=\"https://korben.info/app/uploads/2023/05/pic12.webp 1000w, https://korben.info/app/uploads/2023/05/pic12-300x225.webp 300w, https://korben.info/app/uploads/2023/05/pic12-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Il peut également s’exécuter sur du matériel non-Apple, comme la carte Pegasos, la carte Teron ou encore du matériel AmigaOne. En bref, MOL doit pouvoir s’exécuter sur n’importe quel matériel PowerPC.</p>\n\n\n\n<p>À partir de là, l’installation de MOL est assez easy. Dans la section de téléchargement du site web de MOL, vous trouverez des RPM précompilés. Vous devez télécharger deux paquets : le binaire user de mol et le module de noyau de mol. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-638272512\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Le paquet mol-kmods contient des modules de noyau compilés pour plusieurs noyaux différents. Les noyaux fournis avec les principales distributions Linux sont normalement pris en charge.</p>\n\n\n\n<p>Les RPM peuvent être installés en donnant les commandes suivantes (en tant que root) :</p>\n\n\n\n<pre class=\"wp-block-preformatted\"><code>rpm -i mol-kmods-0.9.60-1.ppc.rpm</code>\n<code>rpm -i mol-0.9.60-1.ppc.rpm</code></pre>\n\n\n\n<p>Si la partie du module du noyau doit être recompilée, installez simplement le paquet mol :</p>\n\n\n\n<pre class=\"wp-block-preformatted\"><code>rpm -i mol-0.9.60-1.ppc.rpm --nodeps</code></pre>\n\n\n\n<p>Configurez ensuite la vidéo plein écran en utilisant l’utilitaire <em>molvconfig</em>. Pensez également à indiquer à MOL les volumes HFS que vous souhaitez utiliser. Cela se fait dans le fichier /etc/molrc. </p>\n\n\n\n<p>Ainsi, une ligne comme celle-ci :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>blkdev : /dev/hda -rw</code></pre>\n\n\n\n<p>…indique à MOL d’utiliser toutes les partitions HFS[+] trouvées sur /dev/hda (premier disque IDE), en autorisant l’accès en écriture. Les partitions non HFS ne seront pas touchées.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-346593223\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Une fois que vous avez installé à la fois le binaire user et le module du noyau, et configuré l’outil, il est temps de vérifier que MOL fonctionne comme prévu.</p>\n\n\n\n<p>Lancez cette commande pour vérifier que tout est OK (vous devez être root la première fois) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>startmol --loadonly</code></pre>\n\n\n\n<p>Puis démarrez OSX avec cette commande : </p>\n\n\n\n<p><code>startmol --osx</code></p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2023/05/pic11.webp\" alt=\"\" class=\"wp-image-152477\" srcset=\"https://korben.info/app/uploads/2023/05/pic11.webp 1000w, https://korben.info/app/uploads/2023/05/pic11-300x225.webp 300w, https://korben.info/app/uploads/2023/05/pic11-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Et admirez Mac OS X s’ouvrir dans toute sa majestuosité ^^.</p>\n\n\n\n<p><a rel=\"noopener\" href=\"https://www.maconlinux.net/\" target=\"_blank\">À découvrir ici</a></p>\n",

C’est un outil hyper pratique qui s’appelle <strong>Reggy</strong>. Reggy c’est notre super-héros qui vient à notre rescousse pour créer en 1 seconde, des identités totalement aléatoires et nous permettre de nous inscrire rapidement sur n’importe quel site sans dévoiler notre identité réelle ! </p>\n\n\n\n<p>Voilà comment fonctionne cette merveille : une fois l’extension installée sur Google Chrome, celle-ci propose un « remplisseur » de formulaire intégré. Ainsi, plus besoin de perdre du temps à chercher des informations à entrer dans les champs obligatoires des formulaires. Reggy les génère rapidement pour vous, tout en gardant le tout cohérent et crédible. À l’aide de cette extension, vous pourrez alors vous inscrire sur n’importe quel site en quelques secondes et sans avoir à réfléchir à deux fois. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230524-gxmq.webp\" alt=\"\" class=\"wp-image-152470\" width=\"386\" height=\"445\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230524-gxmq.webp 650w, https://korben.info/app/uploads/2023/05/SCR-20230524-gxmq-260x300.webp 260w\" sizes=\"(max-width: 386px) 100vw, 386px\" /></figure></div>\n\n\n<p>J’ai été scotché par la façon dont Reggy génère les identités. Les noms et les informations semblent vraiment réels. Un autre point fort de cet outil est que, en plus des identités aléatoires pour le formulaire d’inscription, il peut également générer des adresses email temporaires pour vous protéger contre les messages indésirables. Comme ça, si vous souhaitez essayer de nouveaux services sans pour autant inonder votre boîte de mails publicitaires, cet outil est fait pour vous. </p>\n\n\n\n<p>Et voilà ! En quelques clics, Reggy vous aura permis de vous inscrire sur n’importe quel site, en vous faisant gagner du temps et évitant de partager des informations personnelles inutiles.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1418877749\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>N’oubliez pas que l’utilisation de Reggy ne doit pas être utilisée à des fins illégales ou pour contourner des restrictions importantes, comme ouvrir un compte sur une banque en ligne ou sur des services gouvernementaux qui exigent une vérification d’identité. Prison direct sinon !! L’outil est surtout destiné à simplifier le processus d’inscription sur les sites et à protéger votre vie privée lorsque cela est possible et bien sûr légal. </p>\n\n\n\n<p><strong><a href=\"https://chrome.google.com/webstore/detail/reggy/pnneajlgffpejnabhionnhdfhibijihe/\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></strong> !</p>\n",

Je l’ai testé et c’est vraiment cool.</p>\n\n\n\n<p>Comme vous le savez, beaucoup d’entre nous souhaitent garder leur vie privée et naviguer sur le web de manière anonyme, que ce soit pour éviter les publicités ciblées, accéder à des contenus bloqués, ou simplement pour empêcher les géants du web de nous suivre partout.</p>\n\n\n\n<p>C’est là qu’intervient Vytal. Cette extension Chrome a été développée avec un objectif simple en tête: aider les utilisateurs à naviguer sur le web en toute confidentialité en leur permettant de modifier les données perso renvoyées par le navigateur.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230524-gjxq-2.webp\" alt=\"\" class=\"wp-image-152459\" width=\"260\" height=\"336\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230524-gjxq-2.webp 581w, https://korben.info/app/uploads/2023/05/SCR-20230524-gjxq-2-232x300.webp 232w\" sizes=\"(max-width: 260px) 100vw, 260px\" /></figure></div>\n\n\n<p>Vytal vous permet ainsi de modifier et personnaliser un certain nombre de paramètres pour apparaître comme si vous accédiez à Internet depuis un emplacement, une région, ou un appareil différent. Vous pouvez ainsi changer votre fuseau horaire, votre localisation, votre géolocalisation, et votre user agent.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1045126709\" data-NKSYD1CP-trackid=\"124507\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Avec Vytal, vous pouvez choisir de vous faire passer pour un utilisateur se trouvant dans un autre pays, voire sur un autre continent, mais attention, il ne modifiera pas votre IP, donc c’est complémentaire d’un bon vieux VPN.</p>\n\n\n\n<p>Vous vous demandez peut-être comment Vytal parvient à tromper les sites web que vous visitez ? Et bien, la réponse réside dans l’API chrome.debugger que Vytal utilise pour modifier les données de votre navigateur. Cela permet à l’extension de fonctionner de manière totalement indétectable.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230524-gjuo.webp\" alt=\"\" class=\"wp-image-152461\" width=\"279\" height=\"356\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230524-gjuo.webp 587w, https://korben.info/app/uploads/2023/05/SCR-20230524-gjuo-235x300.webp 235w\" sizes=\"(max-width: 279px) 100vw, 279px\" /></figure></div>\n\n\n<p>Comparée à d’autres extensions du marché, Vytal se distingue par sa facilité d’utilisation et sa transparence. Pas de collecte de données en arrière-plan, pas de publicité intrusive. Tout est fait pour vous offrir l’expérience de navigation la plus sécurisée et anonyme possible.</p>\n\n\n\n<p>Vytal fonctionne également très bien avec d’autres extensions de confidentialité et de sécurité telles que <a href=\"https://chrome.google.com/webstore/detail/stealthy/ieaebnkibonmpbhdaanjkmedikadnoje?hl=fr\" target=\"_blank\" rel=\"noopener\">Stealthy</a>, <a href=\"https://chrome.google.com/webstore/detail/lockpw/kjcloihghgncbdkaafgkckbokjnehfmo\" target=\"_blank\" rel=\"noopener\">LockPW</a> et <a href=\"https://chrome.google.com/webstore/detail/webrtc-control/fjkmabmdepjfammlpliljpnbhleegehm?hl=fr\" target=\"_blank\" rel=\"noopener\">WebRTC Control</a>. Il est donc conseillé de les utiliser ensemble pour renforcer votre anonymat en ligne.</p>\n\n\n\n<p>Pour terminer, je tiens à mentionner que Vytal est entièrement gratuit. Les développeurs travaillent dur pour fournir un outil de qualité à la communauté, sans chercher à monétiser leurs efforts. Si vous êtes convaincu par le potentiel de cette extension et souhaitez les remercier, n’hésitez pas à leur faire un petit don ou à contribuer au projet.</p>\n\n\n\n<p>Voilà pour ma découverte du jour. Je vous recommande vivement de tester Vytal. Qui sait, vous pourriez trouver cet outil indispensable pour préserver votre vie privée en ligne ?</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-254727568\" data-NKSYD1CP-trackid=\"124508\" data-NKSYD1CP-trackbid=\"1\" class=\"NKSYD1CP-target\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p><a href=\"https://vytal.io/\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Et on m’a dit qu’il fallait que j’en fasse un peu plus la pub, donc rejoignez-nous. Vous y retrouverez d’autres passionné(e)s comme vous ! En tout cas, ça me fait plaisir de voir cette petite communauté grandir et s’entraider chaque jour.</p>\n\n\n\n<p>Merci également à tous <a href=\"https://patreon.com/korben\" target=\"_blank\" rel=\"noopener\">les membres du <strong>Patreon</strong></a> qui soutiennent mon travail et me permettent de continuer à produire du contenu rien que pour eux.

Donc normalement, plus de chiens qui se baladent partout dans mon jardin en mode portenawak ni de boucan de bagnoles, coups de feu, mecs qui braillent tout le weekend comme si j’habitais en centre-ville de Marseille. Enfin, jusqu’à la prochaine fois…</p>\n\n\n\n<p>Aussi ce week-end, je me suis habillé en stabilo orange (sécurité oblige) pour débiter un nouvel arbre qui était tombé à cause du vent. Y’a plus qu’à laisser sécher ce futur bois de chauffage pendant quelques années. Vive la tronçonneuse ! Et oui j’ai mal partout, mais j’ai conservé mes 2 jambes. Ces activités en plein air, c’est mieux que Basic Fit.</p>\n\n\n\n<p>Avec la fin des vacances de février, c’est aussi un grand plaisir de retrouver tout le monde, que ce soit sur <a href=\"http://twitch.tv/korbenFR\" target=\"_blank\" rel=\"noopener\">Twitch</a> ou <a href=\"http://tiktok.com/@korbeninfo\" target=\"_blank\" rel=\"noopener\">TikTok</a>. C’est l’occasion de reprendre nos échanges passionnés ;-).</p>\n\n\n\n<p>J’ai également commencé une série que je trouve très cool : The Orville. Même si elle n’est pas récente, elle est très fun. C’est un genre de Star Trek en rigolo. Ça permet de se détendre après une grosse journée. Je vous la conseille.</p>\n\n\n\n<p>Voilà pour les news. Et surtout, n’oubliez pas de vous accrocher à vos projets et de continuer à apprendre chaque jour. J’espère d’ailleurs que j’y contribue un peu. La clé du succès est la persévérance donc ne lâchez rien !</p>\n\n\n\n<p>À bientôt !</p>\n",

Le plus souvent à votre insu. Je vous ai aussi fait <a href=\"https://korben.info/incogni-cnil.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-cnil.html\">un petit article</a> sur les lois qu’ils sont censés respecter. Mais ce que je n’ai pas encore abordé c’est <strong>la manière dont cela peut vous porter directement préjudice</strong>.</p>\n\n\n\n<p>Évidemment, savoir que nos infos (parfois privées) se promènent un peu partout n’est déjà pas très fun en soit. Mais réaliser qu’il y a en plus un risque qu’elles se retournent contre nous pour impacter négativement notre vie, c’est encore un autre stade. Et Incogni vient à nouveau vous prêter main-forte.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"270\" decoding=\"async\" src=\"https://media.giphy.com/media/vP5tCg09mctxuPwY1C/giphy-downsized-large.gif\" alt=\"\"/></figure></div>\n\n\n<p>Si vous avez lu mes articles précédents vous connaissez le principe de base : <strong>les data brokers récupèrent des tonnes d’informations</strong> depuis de nombreuses sources (base de données revendues/hackées, profils sociaux, données publiques, cookies publicitaires …). Ils croisent alors ces différentes datas afin de créer un profil numérique le plus complet possible pour chaque internaute et les classer dans différentes catégories d’audience (joueurs de console PlayStation, ménagère dont le hobby est la cuisine, grand sportif …). Je parie qu’ils ont même créé une catégorie rien que pour moi : chef d’Internet éleveur de poules ou débroussailleur poseur placo.</p>\n\n\n\n<p>Et quand je parle de « chaque internaute » je ne pense pas être trop loin de la réalité. Vous avez un compte Amazon ? À moins d’interdire les cookies, vos infos sont revendues à plusieurs dizaines de boites. En 2022 la CNIL a généré pour plus de 100 millions d’amendes autour du <strong>mauvais respect de la protection des données personnelles des Français</strong>. Et « tout le monde » y est passé : Microsoft, Apple, Facebook (quelle surprise!) … même EDF et plus récemment l’éditeur de jeux mobiles Voodoo (Helix Jump, Paper.io …).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"650\" height=\"200\" decoding=\"async\" src=\"https://me.korben.info/cyt-incogni-risques-databrokers\" alt=\"\"/></figure></div>\n\n\n<p>Sauf que, en plus de ne pas respecter notre intimité, le profil qui est créé n’est pas forcément toujours précis ni d’actualité. Il peut y avoir des zones d’ombres, des données périmées, un flou en fonction de la véracité même des infos que vous renseignez, des outils et services que vous utilisez au quotidien, du nombre de profils que vous utilisez, etc.</p>\n\n\n\n<p>Or cela peut poser problème lorsque l’organisme qui achète vos infos est une banque, une assurance ou encore une entreprise qui recrute. Et que ces derniers prennent une décision basée sur un profil qui ne représente plus votre situation actuelle. Aux USA, il y a déjà quelques années, un homme s’est ainsi vu refuser un boulot à cause de données erronées récoltées par son potentiel employeur. Il a par la suite <a href=\"https://casetext.com/case/smith-v-lexisnexis-screening-solutions-inc\" data-type=\"URL\" data-id=\"https://casetext.com/case/smith-v-lexisnexis-screening-solutions-inc\" target=\"_blank\" rel=\"noreferrer noopener\">gagné un procès</a> contre le courtier ayant revendu ses infos, car il n’a pas été possible de prouver à 100% que tout le concernait. L’avantage de porter un nom assez bateau comme David Smith 😉</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"270\" decoding=\"async\" src=\"https://media.giphy.com/media/WOrD6XwdYtkr2DZ0U7/giphy-downsized-large.gif\" alt=\"\"/><figcaption class=\"wp-element-caption\">Exemple de famille Smith en train de brouiller les pistes</figcaption></figure></div>\n\n\n<p>Vous voyez que, sur un malentendu, cela peut mal tourner. La meilleure protection à ce niveau reste de supprimer ses traces le plus tôt possible :</p>\n\n\n\n<ul>\n<li>ne pas créer un compte si ce n’est pas nécessaire</li>\n\n\n\n<li>ne pas donner plus d’infos que le minimum requit pour faire fonctionner le service demandé</li>\n\n\n\n<li>utiliser des outils et services adaptés (navigateur axé vie privée, messagerie chiffrée …)</li>\n\n\n\n<li>faire supprimer les données déjà stockées chez les data brokers</li>\n</ul>\n\n\n\n<p>Pour ce dernier point, vous pouvez vous tourner les yeux fermés <a href=\"https://korben.info/incogni-test.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-test.html\">vers Incogni</a>. Le service de Surfshark sera d’une aide précieuse pour faire disparaitre les informations qui sont déjà présentes dans les listes des courtiers.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"800\" height=\"414\" src=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg\" alt=\"\" class=\"wp-image-130591\" srcset=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg 800w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-300x155.jpg 300w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-768x397.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" /></figure></div>\n\n\n<p>Déjà, le service vous permet de définir votre propre niveau de granularité (chaque fois que j’écris ce mot je pense aux granulés de bois pour pellet, c’est grave docteur ?). Quelles sont les informations que vous voulez laisser visibles et quelles sont celles que vous voulez faire supprimer ? Une fois que vous avez fait vos choix, Incogni va alors contacter les data brokers au cas par cas afin de leur rappeler vos droits et demander les suppressions nécessaires dans les bases de données.</p>\n\n\n\n<p>Et si les brokers esquivent la demande ? Incogni va les relancer encore et encore, jusqu’à ce que ça finisse pas passer. Une fois que c’est fait, l’outil continue à surveiller du coin de l’oeil que le broker ne vous remet pas dans sa base. Bref il y a un vrai suivi et, en plus de protéger votre vie privée, cela va vous faire économiser des heures de travail.</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Découvrir le service Incogni !</a></h2>\n",

Mais aujourd’hui, en lieu et place d’un test classique, j’avais envie d’accentuer les points forts de ces nouveaux jeux, en faisant une liste de ce que j’ai trouvé cool. 🙂 Bien sûr, je vous parlerais quand même de ce qui m’a déçu, et à la toute fin je vous donnerai mon avis de gamer chevronné !</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Pokémon Écarlate & Pokémon Violet – Maintenant disponibles !

Ce nouveau Pokémon suit les traces de pattes de <a href=\"https://amzn.to/3EFd1sQ\" target=\"_blank\" rel=\"noopener\">Légendes Pokémon Arceus</a> et propose des environnements ouverts, à explorer à notre guise. Dès le départ (enfin, après une séquence de didacticiel qui met en place l’histoire), on peut choisir par quel côté débuter notre expédition, par définir quel objectif atteindre en priorité, etc. C’est aussi rafraîchissant qu’un verre de lait meumeu !</p>\n\n\n\n<p>Et malgré cette réelle liberté, la progression est plutôt bien dosée. On débloque régulièrement des pouvoirs pour notre monture, ce qui nous permet d’atteindre de nouvelles zones. Le niveau des Pokémons rencontrés correspond plutôt bien à notre niveau à nous (et quand ce n’est pas le cas ce n’est pas trop gênant), là dessus, c’est bien foutu. Le scénario sort un peu du schéma habituel et on prend plaisir à avancer à son rythme.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https://amzn.to/3Z3Q2jj\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-2-1024x576.webp\" alt=\"\" class=\"wp-image-132851\" srcset=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-2-1024x576.webp 1024w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-2-300x169.webp 300w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-2-768x432.webp 768w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-2.webp 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></a></figure>\n\n\n\n<h2>2) L’école forbuissonnière</h2>\n\n\n\n<p>Au centre de la map : l’Académie. Ce n’est pas précisé clairement au départ, mais je vous conseille de vous y rendre régulièrement entre deux “missions”, car il y a des leçons à débloquer, ça nous apprend pas mal de subtilités sur le <em>gameplay </em>ou l’univers du jeu : y a des mini-quêtes, on va tisser des liens avec les profs et quelques élèves, et ça structure un peu notre progression. Et puis ça permet de récupérer plein de récompenses facilement. 😀</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-379253135\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Ces allers-retours ne sont pas agaçants, car dès le départ de l’aventure, on a accès au déplacement rapide (concrètement : téléportation) et la carte nous indique les points intéressants de manière claire. Si l’envie vous prend de chasser les créatures téracristalisées, ou de retourner découvrir une zone précise, c’est faisable !</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https://amzn.to/3Z3Q2jj\"><img decoding=\"async\" loading=\"lazy\" width=\"720\" height=\"405\" src=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-3.webp\" alt=\"\" class=\"wp-image-132852\" srcset=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-3.webp 720w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-3-300x169.webp 300w\" sizes=\"(max-width: 720px) 100vw, 720px\" /></a></figure>\n\n\n\n<h2>3) Des combats pas barbants</h2>\n\n\n\n<p>Je m’explique. 😀 Le système de baston a toujours été sympa, mais parfois un peu fastidieux (écrans de transitions et textes un peu longs, combats aléatoires…). Dans <a href=\"https://amzn.to/3EFd1sQ\" target=\"_blank\" rel=\"noopener\">Arceus</a>, tout cela avait été un peu bouleversé (aucun écran de transition, attaques rapides ou puissantes, Pokémon barons…), et c’était cool. Mais ici ils sont revenus en arrière sur pas mal de points. :’( Heureusement ils ont gardé certains trucs, et ajouté plein de petits détails qui nous facilitent la vie et rendent l’expérience plus fluide et agréable que dans les autres jeux canoniques.</p>\n\n\n\n<p>Capturer un Pokémon demande toujours d’entrer en combat, cependant, se cacher dans les hautes herbes et lui balancer une pokéball par surprise (dans le dos) facilitera grandement l’opération. Manger certains aliments (on peut cuisiner et faire des piques-niques) boostera nos compétences de capture ou autre. Il est possible d’avoir un Pokémon de compagnie qui se balade à nos côtés : il ira se battre automatiquement, engrangeant XP et objets sans intervention de notre part ou presque. Ça nous évite plein de combats superflus, rend l’exploration et le <em>farming </em>plus agréable.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https://amzn.to/3Z3Q2jj\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-4-1024x576.webp\" alt=\"\" class=\"wp-image-132853\" srcset=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-4-1024x576.webp 1024w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-4-300x169.webp 300w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-4-768x432.webp 768w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-4.webp 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></a></figure>\n\n\n\n<h2>4) Une interface qui QoL</h2>\n\n\n\n<p>Plus besoin d’aller voir un NPC précis planqué dans un recoin paumé, pour effectuer certaines action bien précises : les menus sont complets, et nous permettent ENFIN de quasiment tout faire quand on le souhaite (même d’apprendre d’anciennes techniques, de renommer les Pokémons, …). <strong>OUF</strong>.</p>\n\n\n\n<p>Aussi, pour une fois, on a un “vrai” mode multijoueur. On peut se retrouver jusqu’à 4 joueurs dans la même instance, explorer, échanger, faire des photos (🤷), participer à des raids ensemble, etc. L’avancée dans le scénario reste indépendante, car le jeu conserve la progression de chaque joueur, mais il est possible de faire nos quêtes chacun de son côté tout en étant dans le même monde, se retrouver sur la map, faire des échanges, etc.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https://amzn.to/3Z3Q2jj\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"723\" src=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-5-1024x723.webp\" alt=\"\" class=\"wp-image-132854\" srcset=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-5-1024x723.webp 1024w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-5-300x212.webp 300w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-5-768x543.webp 768w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-5.webp 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></a></figure>\n\n\n\n<h2>5) Violet, écarlate, tout n’est pas rose</h2>\n\n\n\n<p>J’apprécie beaucoup ce volet, mais je regrette certains points. Tout d’abord, l’aspect graphique : c’est assez vide, fade, et parfois ça rame… 🙁 Un comble quand on voit certains jeux comme les <a href=\"https://amzn.to/3IZARCu\" target=\"_blank\" rel=\"noopener\">Xenoblade</a>, <a href=\"https://amzn.to/3Y9Rb7M\" target=\"_blank\" rel=\"noopener\">Zelda</a>, ou <a href=\"https://amzn.to/3KGRFPV\" target=\"_blank\" rel=\"noopener\">Dragon Quest XI</a>, beaucoup plus jolis et fluides sur la même console !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-132844566\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Aussi, je trouve dommage que le système de chasse/capture, tel qu’il était implémenté dans <a href=\"https://amzn.to/3EFd1sQ\" target=\"_blank\" rel=\"noopener\">Arceus</a>, ne soit pas de retour. Pareil pour les “barons”, les Pokémon de différentes tailles, etc. C’était vachement fun et ça apportait de la variété au gameplay. Peut-être que la prochaine génération osera faire le mélange de tout ça ?</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https://amzn.to/3Z3Q2jj\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-6-1024x576.webp\" alt=\"\" class=\"wp-image-132855\" srcset=\"https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-6-1024x576.webp 1024w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-6-300x169.webp 300w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-6-768x432.webp 768w, https://korben.info/app/uploads/2023/02/pokemon-ecarlate-violet-6.webp 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></a></figure>\n\n\n\n<h2>Conclusion</h2>\n\n\n\n<p>En dehors de ces quelques regrets, je trouve que c’est un excellent jeu, qui renouvelle l’expérience de belle manière. La durée de vie est plus que correcte, le scénario promet quelques surprises et l’aspect collectionnite est toujours aussi réussi. Ça apporte un bon petit coup de frais à la licence, vraiment agréable, je conseille !</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://amzn.to/3Z3Q2jj\" target=\"_blank\" rel=\"noopener\">Acheter Pokémon Violet</a> ou <a href=\"https://amzn.to/3xUmzwD\" target=\"_blank\" rel=\"noopener\">Écarlate sur Nintendo Switch</a></h2>\n",

C’est assez génial comme idée et je vais tout vous expliquer dans cet article.</p>\n\n\n\n<p>Vous le savez, en ce moment, niveau production électrique en France, ce n’est pas la joie. Il y a chaque jour des pics de consommation naturels parce que les gens rentrent chez eux le soir et allument le chauffage tous en même temps. Pour pallier à ça, en France, on a redémarré des usines de production d’électricité assez polluantes (charbon par exemple) et le gouvernement a même annoncé des coupures d’électricité. Pas cool.</p>\n\n\n\n<p>Et le discours général est : « <em>Que tout le monde fasse des efforts !</em>« .</p>\n\n\n\n<p>À titre personnel, je veux bien faire des efforts, mais je ne vois pas trop ce que je peux faire de plus. Il fait entre 14° et 17° dans la maison et quand je chauffe à mort toute la journée (au bois), c’est la canicule avec un petit 19°. Donc bon, que faire ?</p>\n\n\n\n<p>Et bien l’application <a rel=\"noopener\" href=\"https://me.korben.info/9wu-survoltage\" target=\"_blank\"><strong>Survoltage</strong></a> est peut-être une bonne solution pour tous ceux qui veulent à la fois faire des économies sur leur facture, et participer aux efforts communs demandés à tous les Français. </p>\n\n\n\n<p>L’idée est simple : <strong>décaler notre consommation d’électricité lors des pics.</strong></p>\n\n\n\n<p>Je participe régulièrement à Survoltage depuis quelques semaines donc je peux vous en parler sereinement.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"1920\" height=\"1049\" decoding=\"async\" src=\"https://me.korben.info/gwf-survoltage-trk\" alt=\"\"/></figure></div>\n\n\n<p>Une fois téléchargée sur l’Apple Store ou l’Android Play Store, l’application vous demande de vous créer un compte et de lier votre compteur Linky avec leur service. C’est normal puisqu’ils ont besoin de la donnée précise pour estimer votre « non-consommation ». </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><a href=\"https://me.korben.info/9wu-survoltage\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230131-h8f-2-1024x270.webp\" alt=\"\" class=\"wp-image-132543\" width=\"552\" height=\"145\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230131-h8f-2-1024x270.webp 1024w, https://korben.info/app/uploads/2023/01/SCR-20230131-h8f-2-300x79.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230131-h8f-2-768x202.webp 768w, https://korben.info/app/uploads/2023/01/SCR-20230131-h8f-2-1536x405.webp 1536w, https://korben.info/app/uploads/2023/01/SCR-20230131-h8f-2.webp 1920w\" sizes=\"(max-width: 552px) 100vw, 552px\" /></a></figure></div>\n\n\n<p>Ensuite, quand vient le moment, l’app m’avertit lorsqu’un « effacement » est programmé. En général c’est de 19h à 19h30, voire 20h. Les week-ends, c’est plutôt le matin.</p>\n\n\n\n<p>J’indique sur l’application que je souhaite participer à cet effacement et quand vient l’heure, je coupe ou je ne lance pas certains appareils électriques : Radiateurs, four, lave-vaisselle…etc. Et lorsque c’est fini, je rallume à nouveau mes appareils électriques.</p>\n\n\n\n<p>En faisant ça, je décale ma consommation électrique et cela présente plusieurs avantages. Tout d’abord, je participe à l’effort commun lors des pics de consommation électrique. Bruno Lemaire est fier de moi ^^ ! </p>\n\n\n\n<p>Ensuite, j’économise de l’argent puisque pendant 1h, mon chauffage n’a pas tourné (et rassurez-vous, ça ne change pas grand-chose niveau confort puisqu’il y a quand même une certaine inertie dans la maison).</p>\n\n\n\n<div class=\"wp-block-jetpack-tiled-gallery aligncenter is-style-rectangular\"><div class=\"tiled-gallery__gallery\"><div class=\"tiled-gallery__row\"><div class=\"tiled-gallery__col\" style=\"flex-basis:50.05919%\"><figure class=\"tiled-gallery__item\"><img decoding=\"async\" srcset=\"https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?strip=info&w=600&ssl=1 600w,https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?strip=info&w=900&ssl=1 900w,https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?strip=info&w=1200&ssl=1 1200w,https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?strip=info&w=1267&ssl=1 1267w\" alt=\"\" data-height=\"2560\" data-id=\"132540\" data-link=\"https://korben.info/?attachment_id=132540\" data-url=\"https://korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp\" data-width=\"1267\" src=\"https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?ssl=1\" data-amp-layout=\"responsive\"/></figure></div><div class=\"tiled-gallery__col\" style=\"flex-basis:49.94081%\"><figure class=\"tiled-gallery__item\"><img decoding=\"async\" srcset=\"https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?strip=info&w=600&ssl=1 600w,https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?strip=info&w=900&ssl=1 900w,https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?strip=info&w=1200&ssl=1 1200w,https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?strip=info&w=1264&ssl=1 1264w\" alt=\"\" data-height=\"2560\" data-id=\"132541\" data-link=\"https://korben.info/?attachment_id=132541\" data-url=\"https://korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp\" data-width=\"1264\" src=\"https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?ssl=1\" data-amp-layout=\"responsive\"/></figure></div></div></div></div>\n\n\n\n<p>Enfin, il faut savoir qu’une énergie décalée, c’est une énergie qui ensuite n’est pas à 100% reconsommée donc ça fait encore des économies de ce point de vue là.</p>\n\n\n\n<p>Et pour nous récompenser de ce qu’on n’a pas consommé, Survoltage nous offre des points qui seront plus tard échangeables contre des euros ou des dons (ils attendent une certification pour ça). Donc on y gagne sur tous les tableaux pour un peu qu’on joue le jeu de couper le jus aux bons moments.</p>\n\n\n\n<p>Certains se contentent de baisser le chauffage ou de lancer un lave-linge un peu plus tard, alors que d’autres utilisateurs coupent carrément le disjoncteur et partent faire un tour pendant 1h. Ensuite, ce que vous n’avez pas consommé est comptabilisé dans l’application et vous pouvez voir ce que vous avez économisé + les points E-Watts gagnés + la quantité de CO2 économisés ce qui fait de vous les premiers écologistes de France et viendra au fil du temps compenser un peu l’empreinte carbone de votre iPhone dernier cri 🙂</p>\n\n\n\n<p>Alors je vous rassure, rien n’est obligatoire. Si certains jours, vous ne pouvez pas réduire votre consommation ou que vous zappez, pas de soucis.</p>\n\n\n\n<p>Voila c’est comme ça que fonctionnent les opérateurs d’effacement. Ils aident le réseau électrique à effacer la crête des pics de consommation. Les marchés européens leur paye l’électricité non consommée au même tarif qu’une électricité consommée et Survoltage en reverse environ 60%. D’après Survoltage, en jouant le jeu tous les jours, vous pouvez gagner jusqu’à 15% d’économie sur votre facture à l’année en plus des points EWATT gagnés.</p>\n\n\n\n<p>Un truc intéressant avec Survoltage, c’est que vous pouvez également automatiser la coupure de vos appareils avec votre domotique et un compte IFTTT (ça utilise des webhooks). Idéal pour les têtes en l’air !</p>\n\n\n\n<p>Et bien sûr l’application est totalement gratuite. Le mieux c’est donc de l’installer et de tester le concept pour voir si ça convient avec votre rythme. En tout cas, il y a un petit côté addictif de voir les points s’accumuler ainsi que les économies de CO2 et même mes enfants sont fans de jouer au jeu « Survoltage » le soir.</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://me.korben.info/9wu-survoltage\" target=\"_blank\" rel=\"noopener\">TÉLÉCHARGER SURVOLTAGE</a></h2>\n",

Ce programme qui peut tourner sous Windows, macOS et Linux a juste besoin lors de sa compilation de la ROM d’origine dans sa première version US du jeu pour en extraire les ressources (les niveaux, les images, les musiques) qui sont évidemment encore copyrightées.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230123-k3z.webp\" alt=\"\" class=\"wp-image-132389\" width=\"496\" height=\"458\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230123-k3z.webp 832w, https://korben.info/app/uploads/2023/01/SCR-20230123-k3z-300x277.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230123-k3z-768x709.webp 768w\" sizes=\"(max-width: 496px) 100vw, 496px\" /></figure></div>\n\n\n<p>Mais une fois que c’est fait, il y a plus qu’à lancer le binaire et vous pourrez jouer nativement au jeu Zelda – Link To The Past. Le développeur a également ajouté quelques fonctionnalités qui ne sont pas dans le code d’origine comme la possibilité de remplir ses coeurs et sa magie (oui c’est de la triche), de choper une clé de donjon bonus, voire même de faire les donjons en speedrun (CTRL + 1-9).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"637\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230123-kbw.webp\" alt=\"\" class=\"wp-image-132388\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230123-kbw.webp 1024w, https://korben.info/app/uploads/2023/01/SCR-20230123-kbw-300x187.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230123-kbw-768x478.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Pour compiler le jeu sous Windows, ce n’est pas compliqué et ça peut se faire avec TCC ou Visual Studio <a href=\"https://github.com/Xbox-Homebrew/zelda3\" target=\"_blank\" rel=\"noopener\">mais je vous invite à lire la doc ici</a> pour procéder à la manoeuvre.</p>\n\n\n\n<p>Et pour compiler ce jeu sous Linux ou macOS, vous aurez besoin de Python et de Pip. Lancez ensuite les commandes suivantes : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/snesrev/zelda3\ncd zelda3\npython3 -m pip install -r requirements.txt</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-382436833\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Après vous aurez besoin de SDL2 qui s’installe comme ceci sous Linux (Ubuntu) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo apt install libsdl2-dev</code></pre>\n\n\n\n<p>Et sous macOS : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>brew install sdl2</code></pre>\n\n\n\n<p>Ensuite, il faudra vous procurer la ROM zelda3.sfc et la placer dans le répertoire <em>zelda3/tables</em></p>\n\n\n\n<p>Ensuite, toujours dans le répertoire zelda3, lancez la commande :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>make</code></pre>\n\n\n\n<p>Et voilà, vous aurez un joli binaire zelda3 à lancer. Notez que le code peut également être compilé pour votre Nintendo Switch.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230123-k0u.webp\" alt=\"\" class=\"wp-image-132392\" width=\"469\" height=\"433\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230123-k0u.webp 832w, https://korben.info/app/uploads/2023/01/SCR-20230123-k0u-300x277.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230123-k0u-768x709.webp 768w\" sizes=\"(max-width: 469px) 100vw, 469px\" /></figure></div>\n\n\n<p>Ensuite, vous noterez la présence d’un fichier zelda3.ini qui vous permettra de modifier certains paramètres du jeu, comme la résolution, le son ou encore les touches du clavier. Ce qui est très pratique. Et surtout, comme les sources sont dispo, il est parfaitement envisageable de totalement modifier le jeu, changer les sprites, la musique, les dialogues…etc.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230123-kad.webp\" alt=\"\" class=\"wp-image-132391\" width=\"405\" height=\"351\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230123-kad.webp 883w, https://korben.info/app/uploads/2023/01/SCR-20230123-kad-300x261.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230123-kad-768x668.webp 768w\" sizes=\"(max-width: 405px) 100vw, 405px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-174129331\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Bref, de quoi vous refaire tout Zelda Link To The Past, pépouze nativement sur votre ordinateur, avec de bonnes performances et surtout quelques possibilités de triche afin de ne pas trop être frustré.

Alors bien sûr quand XGIMI m’a proposé de tester le <a rel=\"noopener\" href=\"https://me.korben.info/xgimilink\" target=\"_blank\"><strong>HORIZON Pro</strong></a>, j’ai évidemment accepté car j’étais très curieux de voir toutes les évolutions qu’il y a eu en matière de vidéo projecteur depuis toutes ces années, et je dois vous dire que je n’ai pas été déçu. Pour info, je vous ai également mis un code promo à la fin de l’article qui permet d’obtenir 200 euros de réduction sur l’appareil.</p>\n\n\n\n<p>XGIMI est une marque qui a été lancé en 2013 et qui travaille pas mal de partenaires comme Google, Harman Kardon ou encore Texas Instruments. Leur coeur de métier, ce sont les « appareils de divertissement tout-en-un » et leur philosophie c’est « user-first », c’est à dire créer des produits simple à prendre en main et efficaces.</p>\n\n\n\n<p>Je sais pas si vous avez un projecteur, alors je vais d’abord vous parler de mon expérience « projo ». J’ai un beau mur blanc à la maison, un chouette canapé, et c’est un grand plaisir de pouvoir voir un film « en grand, comme au cinéma ». </p>\n\n\n\n<p>J’habite pas à côté d’un multiplex et le cinéma de quartier a un écran rikiki. Ajoutez à ça les sans gênes qui parlent, les grands mères qui éclairent la salle avec leur smartphone parce qu’elle cherchent un truc dans leur sac à main ou encore les boulets qui tapent dans les sièges avec leurs gros genoux, sans oublier le prix prohibitif du ticket et l’impossibilité de mettre en pause quand on veut faire une pause pipi… </p>\n\n\n\n<p>Vous l’aurez compris, je suis plutôt guéri de « l’expérience cinéma » et j’adore mon projecteur à la maison, que j’utilise vraiment pour cette expérience (et pas pour mater la TV de la vie de tous les jours).</p>\n\n\n\n<h2>On passe au test !</h2>\n\n\n\n<p>Ça fait donc une petite semaine que j’ai troqué mon vieux coucou contre le <a rel=\"noopener\" href=\"https://me.korben.info/xgimilink\" target=\"_blank\"><strong>XGIMI HORIZON Pro</strong></a> et je ne suis pas déçu de la qualité de l’expérience. C’est encore mieux. Ce projecteur dispose d’un moteur optique 4K, d’une résolution de 3840 x 2160, soit 8,29 millions de pixels.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img width=\"1024\" height=\"768\" decoding=\"async\" src=\"https://me.korben.info/a89-xgimitrk\" alt=\"\"/></figure>\n\n\n\n<p>Autant dire que les films sont encore plus sympa qu’avant même si j’ai découvert à cette occasion que Netflix voulait m’escroquer un forfait supérieur pour de la 4K. Non merci :-).</p>\n\n\n\n<p>Habituellement, regarder un film sur un projo quand il fait jour dehors, c’est moyen. Mais avec sa luminosité de 2200 ANSI lumens, c’est parfaitement faisable et tout aussi agréable qu’en soirée. D’ailleurs si vous vous demandez à quelle taille d’écran le HORIZON Pro correspond avec sa résolution, c’est comme si vous aviez une TV de 200 pouces de diagonales (soit 4,42 mètres sur 2,52 mètres).

J’ai fait quelques tests avec des vidéos 4K le HDR-10 (pour un max de contrastes) et X-VUE 2.0 qui permet d’avoir une qualité de fou en terme de rendu d’image, avec des couleurs vives, des noirs profond et même une réduction du « bruit » présent sur l’image (+ de clarté quoi).</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"768\" src=\"https://korben.info/app/uploads/2023/01/xgimi-1024x768.webp\" alt=\"\" class=\"wp-image-132510\" srcset=\"https://korben.info/app/uploads/2023/01/xgimi-1024x768.webp 1024w, https://korben.info/app/uploads/2023/01/xgimi-300x225.webp 300w, https://korben.info/app/uploads/2023/01/xgimi-768x576.webp 768w, https://korben.info/app/uploads/2023/01/xgimi-1536x1152.webp 1536w, https://korben.info/app/uploads/2023/01/xgimi-2048x1536.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>La techno MEMC, que je ne connaissais pas avant, vient également améliorer la fluidité de l’image, réduisant la latence, faisant disparaitre les images fantômes et compensant la perte de détail sur l’image. C’est très sympa surtout pour les amateurs de films d’action ou les gamers qui voient ainsi leur expérience visuelle grandement améliorée (on évite la nausée).</p>\n\n\n\n<p>Et même si j’ai déjà des lunettes qui filtrent la lumière bleue, et bien sachez que ce projecteur protégera vos petits yeux grâce à sa réduction native de la lumière bleue.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"768\" src=\"https://korben.info/app/uploads/2023/01/IMG_9567-1024x768.webp\" alt=\"\" class=\"wp-image-132516\" srcset=\"https://korben.info/app/uploads/2023/01/IMG_9567-1024x768.webp 1024w, https://korben.info/app/uploads/2023/01/IMG_9567-300x225.webp 300w, https://korben.info/app/uploads/2023/01/IMG_9567-768x576.webp 768w, https://korben.info/app/uploads/2023/01/IMG_9567-1536x1152.webp 1536w, https://korben.info/app/uploads/2023/01/IMG_9567.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<h2>Il s’adapte à toutes les surfaces</h2>\n\n\n\n<p>Et surtout, au niveau des fonctionnalités de réglage, je me suis régalé. Avant je devais jouer avec les molettes pour régler la netteté de l’image, mais avec ce nouveau projecteur, c’est un autre délire. Comme il est équipé de la technologie d’Adaptation Intelligente de l’Ecran (ISA), il est capable de proposer une mise au pointe entièrement automatique ainsi qu’une correction de la distorsion trapézoïdale (si votre projo n’est pas pile poile en face de votre mur ou que votre mur n’est pas droit). Il dispose même d’un mode de contournement intelligent des obstacles, ce qui permet de régler l’affichage pour qu’il esquive un tableau sur le mur ou une plante verte.</p>\n\n\n\n<p>Voici une démo où il esquive le fond vert et fait la mise au point tout seul. Puis je règle l’angle de la projection avec la télécommande.</p>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https://korben.info/app/uploads/2023/01/output.webm\"></video></figure>\n\n\n\n<p>Pour la hauteur d’affichage, pas de pied réglable par contre. Donc il faudra vous procurer un trépied réglable, un support ou tout simplement un meuble à la bonne hauteur. Moi j’ai juste calé un petit bouquin en dessous pour lui donner la bonne inclinaison.</p>\n\n\n\n<p>Ensuite, ce que je peux vous dire qu’il est très silencieux. C’est pas une soufflerie comme d’autres vidéo projecteur de qualité moindre. Et il embarque un système audio Harman Kardon, soit 2 haut-parleurs large bande actifs de 8 W chacun, développés spécifiquement pour lui. Du coup, j’ai pas besoin de brancher d’enceintes ou de mettre un casque pour avoir un son de qualité cinéma DTS-HD et DTS Studio Sound, compatible Dolby Digital.</p>\n\n\n\n<h2>Et le logiciel ?</h2>\n\n\n\n<p>Au niveau du soft, c’est de l’Android TV avec bien sûr Google Play pour pouvoir installer toutes les applications que vous voulez (Molotov, Amazon Prime, Netflix, Disney Plus mais également des jeux ou des applications comme Spotify…etc). Comme Android TV embarque un système de commande vocale « OK Google », vous pouvez même piloter le projecteur à la voix. Et si ce n’est pas votre truc, il y a bien sûr une télécommande en plastique et métal avec une bonne prise en main (elle est suffisamment lourde pour ne pas faire toc) et est vraiment très agréable à utiliser.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"768\" src=\"https://korben.info/app/uploads/2023/01/IMG_9510.webp\" alt=\"\" class=\"wp-image-132378\" srcset=\"https://korben.info/app/uploads/2023/01/IMG_9510.webp 1024w, https://korben.info/app/uploads/2023/01/IMG_9510-300x225.webp 300w, https://korben.info/app/uploads/2023/01/IMG_9510-768x576.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Et évidemment pour les gamers, le projecteur dispose d’un mode « jeu » avec une latence basse de 35ms et également d’un mode « 3D » pour ceux qui veulent se repasser Avatar avec les lunettes. Enfin, en matière de connectivité, il y a tout ce qu’il faut à savoir un port DC, 2 ports USB, 2 HDMI, 1 port ethernet, 1 connecteur audio, un connecteur optique, le Bluetooth 5.0 et évidemment, il se connecte en Wifi à votre routeur.</p>\n\n\n\n<p>Si ça vous intéresse, n’hésitez pas à vous renseigner davantage sur les fonctionnalités et les « spécificités » techniques pour vous faire une idée de tout ce que ce projecteur peut vous offrir.</p>\n\n\n\n<h2>200 € de réduction</h2>\n\n\n\n<p>Il est dispo au prix de 1 699 euros sur le site de XGIMI ou sur Amazon et <strong>avec le code promo </strong>« <strong>Korben</strong>« <strong>, vous pouvez économiser 200 euros et obtenir ce projecteur pour 1499 euros</strong> directement sur la page</p>\n\n\n\n<h2 class=\"has-text-align-center\"><strong><a href=\"https://me.korben.info/xgimilink\" data-type=\"URL\" data-id=\"https://me.korben.info/xgimilink\" target=\"_blank\" rel=\"noreferrer noopener\">HORIZON PRO de XGIMI</a></strong></h2>\n\n\n\n<p>Offre valable jusqu’au 6 février.</p>\n",

Pour générer une nouvelle clé de chiffrement, vous pouvez procéder comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>age-keygen -o key.txt</code></pre>\n\n\n\n<p>Celle-ci sera stockée dans key.txt. Ensuite, vous pourrez l’utiliser pour chiffrer un fichier comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>age --encrypt -i key.txt -o fichier.age fichier.txt</code></pre>\n\n\n\n<p>Ou directement avec la clé avec le paramètre -r . Dans l’exemple ci-dessous, je vous montre également qu’on peut chiffrer des fichiers qui seraient le résultat d’une commande (ici une création d’archive tar) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>tar cvz ~/data | age -r age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p > data.tar.gz.age</code></pre>\n\n\n\n<p>Et pour déchiffrer ce fichier : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>age --decrypt -i key.txt fichier.age > fichier.txt</code></pre>\n\n\n\n<p>Et vous pouvez également spécifier plusieurs clés pour tous vos destinataires.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>age -o example.jpg.age -r age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p \\\n -r age1lggyhqrw2nlhcxprm67z43rta597azn8gknawjehu9d9dl0jq3yqqvfafg example.jpg</code></pre>\n\n\n\n<p>Vous pouvez également demander la création d’une phrase de passe avec le paramètre -p.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>age -p fichier.txt > fichier.txt.age</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-675006195\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>L’outil vous demandera alors de saisir une phrase de passe ou la générera pour vous. </p>\n\n\n\n<p>Vous l’aurez compris, pas de clé privée. Juste une grosse clé (publique) qui sert à la fois pour le chiffrement et le déchiffrement. Rassurez-vous, age prend également en charge le chiffrement à partir de clés publiques SSH ssh-rsa et ssh-ed25519, et le déchiffrement se fait avec la clé privée correspondante. Pour chiffrer :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>age -R ~/.ssh/id_ed25519.pub exemple.jpg > exemple.jpg.age</code></pre>\n\n\n\n<p>Pour déchiffrer : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>age -d -i ~/.ssh/id_ed25519 exemple.jpg.age > exemple.jpg</code></pre>\n\n\n\n<p>Attention cela dit, la prise en charge des clés SSH utilise une cryptographie plus complexe et incorpore une balise de clé publique dans le fichier chiffré, ce qui permet de suivre les fichiers chiffrés avec cette clé spécifique.</p>\n\n\n\n<p>Et si ça vous intéresse, une implémentation en Rust est <a href=\"https://github.com/str4d/rage\" target=\"_blank\" rel=\"noopener\">également disponible ici.</a></p>\n\n\n\n<p>De plus, il existe un <a href=\"https://github.com/str4d/age-plugin-yubikey\" target=\"_blank\" rel=\"noopener\">plugin</a> pour ceux qui veulent utiliser leur Yubikey avec ce truc 🙂</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2106157626\"><div id='optidigital-adslot-Content_4' style='display:none;' class=\"Content_4\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos4' style='display:none;' class=\"Mobile_Pos4\"></div></div><p><a rel=\"noopener\" href=\"https://github.com/FiloSottile/age\" target=\"_blank\">À découvrir ici.</a></p>\n",

L’outil surveille si du son provient de Zoom, Teams, Skype, Webex Meetings…etc. Et dès que plus personne ne cause ou qu’il y a un gros blanc, PAF, ça kill le programme de visioconférences.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/autoleavemeeting-shot.webp\" alt=\"\" class=\"wp-image-132292\" width=\"582\" height=\"339\" srcset=\"https://korben.info/app/uploads/2023/01/autoleavemeeting-shot.webp 1024w, https://korben.info/app/uploads/2023/01/autoleavemeeting-shot-300x175.webp 300w, https://korben.info/app/uploads/2023/01/autoleavemeeting-shot-768x448.webp 768w\" sizes=\"(max-width: 582px) 100vw, 582px\" /></figure></div>\n\n\n<p>Évidemment, vous pouvez régler le délai de silence acceptable avant la fermeture automatique du soft. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1518561571\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Comme ça, vous pouvez vous barrer faire autre chose, ou ne plus prêter attention à la réunion et au logiciel de Visio-conf et vous déconnecter comme un boss quand c’est terminé.</p>\n\n\n\n<p>Au top ! Si vous avez d’autres astuces pour télétravailleurs en dépression, ça m’intéresse :).</p>\n",

Vous pouvez également l’installer via Winget avec la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>winget install usbipd</code></pre>\n\n\n\n<p>Une fois installé, l’outil s’utilise en ligne de commande et permet à tous les appareils dispo sur le réseau de se connecter au périphérique USB de votre choix. Rassurez-vous, par défaut, rien n’est partagé. Il faudra lister les périphériques avec la commande : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>usbipd list</code></pre>\n\n\n\n<p>Vous obtiendrez alors une liste de vos périphériques. Ils auront un ID genre : 3-1, 3-5..etc. Pour le mettre sur le réseau, vous devrez alors lancer la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>usbipd bind --busid=X-X</code></pre>\n\n\n\n<p>(Remplacez x-x par 3-5 par exemple)</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230116-kxv.webp\" alt=\"\" class=\"wp-image-132262\" width=\"700\" height=\"165\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230116-kxv.webp 1024w, https://korben.info/app/uploads/2023/01/SCR-20230116-kxv-300x71.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230116-kxv-768x182.webp 768w\" sizes=\"(max-width: 700px) 100vw, 700px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1727598351\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Ensuite, pour vous connecter, utiliser la commande suivante sur le système distant : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>usbip list --remote=HOST</code></pre>\n\n\n\n<p>Et remplacez HOST par l’IP de la machine et voilà, vous aurez accès au périphérique USB comme si vous l’aviez branché sur votre propre machine. Après en fonction de votre réseau, sachez quand même qu’il peut y avoir quelques petits soucis de latence ou de bande passante.</p>\n\n\n\n<p>Vous pouvez également utiliser la sous-commande « usbipd wsl » pour partager et connecter un périphérique avec une seule commande sous WSL2.

Pas besoin d’écrire sur papier et d’aller à la boite aux lettres la plus proche de chez vous.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/IMG_9365.webp\" alt=\"\" class=\"wp-image-132250\" width=\"291\" height=\"630\" srcset=\"https://korben.info/app/uploads/2023/01/IMG_9365.webp 355w, https://korben.info/app/uploads/2023/01/IMG_9365-139x300.webp 139w\" sizes=\"(max-width: 291px) 100vw, 291px\" /></figure></div>\n\n\n<p>Tout se passe sur mobile et une fois votre profil créé, vous pouvez commencer à rédiger une lettre que vous adresserez à quelqu’un que vous aurez choisi sur profil.

Ce temps d’attente dépend de la distance qui vous sépare géographiquement de votre correspondant, comme à l’ancienne.</p>\n\n\n\n<p>Ainsi, chacun peut prendre le temps d’écrire de longues missives et pourquoi pas y joindre quelques photos.

Évidemment déjà à l’époque, je m’intéressais beaucoup à la cybersécurité, mais à ma connaissance, il n’y avait aucune école spécialisée sur ce sujet.</p>\n\n\n\n<p>Heureusement, ça a bien changé, car maintenant, les passionnés de cybersécurité ont l’embarras du choix au niveau des écoles qui forment à des métiers « cyber ».</p>\n\n\n\n<p>Maintenant, la cybersécurité est partout dans notre vie quotidienne et les menaces en ligne (dont je vous parle régulièrement) sont nombreuses. Cela peut provoquer des catastrophes humaines, mais également économiques et c’est aussi un terrain d’affrontement pour les armées du monde entier.</p>\n\n\n\n<p>C’est pour ça que j’aimerai vous présenter le <a rel=\"noopener\" href=\"https://me.korben.info/12e-bts-stcyr-drhat\" target=\"_blank\">BTS Cyber-Défense de Saint Cyr</a> qui est une formation assez unique en son genre puisqu’elle a été lancée en 2017 sur l’initiative de l’Armée de Terre et des services spécialisés du Ministère des Armées. Il s’agit avant tout de répondre aux besoins de recrutement de l’armée en matière de cybersécurité. C’est un peu comme si l’armée vous disait : « <em>Vous aimez la cybersécurité ? Alors, venez nous aider à protéger notre pays !</em> ». </p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Les combattants numériques (#JDEF)\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/s9d50jUXV-w?start=546&feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p><strong>Je suis sûr que si vous êtes encore au lycée</strong>, en sortie de Bac STI2D, Bac Scientifique ou Bac Pro SN, ça peut vous intéresser. Il s’agit d’un <strong>BTS CIEL </strong>(Cybersécurité, Informatique et réseaux, Électronique, anciennement BTS SNIR) reprenant en totalité le programme officiel de l’Éducation Nationale, sauf qu’en plus, ils y ont rajouté des spécificités propres au Ministère des Armées. </p>\n\n\n\n<p>Ce <a href=\"https://me.korben.info/12e-bts-stcyr-drhat\" target=\"_blank\" rel=\"noopener\"><strong>BTS Cyber-Défense de Saint Cyr</strong></a> va bien au-delà d’une simple formation de 2 ans après le bac : c’est carrément une nouvelle vie qui s’offre à ceux qui choisiront cette voie puisqu’un contrat d’engagement est signé avec le Ministère. Vous serez logé (c’est de l’internat), nourri et blanchi avec un peu d’argent de poche et en 2 ans, vous obtiendrez un niveau opérationnel se rapprochant de celui de quelqu’un qui aurait fait une licence. Vous l’aurez compris, c’est une formation intense.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"1024\" height=\"576\" decoding=\"async\" src=\"https://me.korben.info/7uv-bts-stcyr-trk\" alt=\"\"/></figure></div>\n\n\n<p>Et en sortie, lorsque vous réussirez votre diplôme, <strong>un emploi vous sera proposé</strong> (et il sera obligatoire), soit en tant que civil pour rejoindre les services spécialisés du Ministère des Armées (Commandement des systèmes d’information, cyberdéfense, renseignement), soit en tant que militaire, c’est-à-dire que vous intégrerez un régiment quelque part en France. Vous suivrez alors une formation complémentaire spécifique, soit à l’École des Transmissions, soit au sein du service pour lequel vous travaillerez. Et si vous voulez continuer les études, et bien c’est toujours possible et même encouragé, mais uniquement en cours à distance / cours du soir.</p>\n\n\n\n<p>C’est ouvert à toutes les personnes de nationalité française et vous n’avez pas nécessairement besoin d’avoir des connaissances en informatique à l’entrée. Il faut juste être motivé, exigeant avec soi-même et avoir une très bonne capacité de travail. Et surtout, vous l’aurez compris, être bien motivé pour travailler au Ministère des Armées. Notez que les admissions dans cette formation sont également ouvertes aux candidats en réorientation après une première année d’études dans un domaine scientifique ou technique.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/bts2-1024x576.webp\" alt=\"\" class=\"wp-image-132531\" srcset=\"https://korben.info/app/uploads/2023/01/bts2-1024x576.webp 1024w, https://korben.info/app/uploads/2023/01/bts2-300x169.webp 300w, https://korben.info/app/uploads/2023/01/bts2-768x432.webp 768w, https://korben.info/app/uploads/2023/01/bts2.webp 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Alors y’a quoi exactement dans cette formation de 40h de cours par semaine ? </p>\n\n\n\n<p>Et bien évidemment, vous aurez des cours de cybersécurité (connaissance du milieu, défense et attaque) à hauteur de 4h par semaine, des cours d’anglais (4h par semaine au total) avec le passage du TOEIC, histoire d’être au point. Il y a également 4h de sport par semaine donc c’est mieux si vous êtes en bonne condition physique. Et également une préparation militaire supérieure. Ça veut dire que vous allez tout apprendre sur la chose militaire, de la reconnaissance des grades au maniement des armes en passant par une formation de commandement.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/bts3sport-1024x576.webp\" alt=\"\" class=\"wp-image-132528\" srcset=\"https://korben.info/app/uploads/2023/01/bts3sport-1024x576.webp 1024w, https://korben.info/app/uploads/2023/01/bts3sport-300x169.webp 300w, https://korben.info/app/uploads/2023/01/bts3sport-768x432.webp 768w, https://korben.info/app/uploads/2023/01/bts3sport.webp 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Hé oui, c’est indispensable puisqu’après, ceux qui choisiront la voie militaire pourront se retrouver en train de taper des lignes de commande dans un shell lors d’une opération dans un pays étranger. Bref, un boulot de technicien supérieur dans des conditions de travail exceptionnelles, des moyens uniques avec des missions que vous ne pourriez jamais réaliser dans une entreprise classique, comme de la lutte informatique réellement offensive.</p>\n\n\n\n<p>Voici un peu à quoi ressemble le quotidien d’une personne qui a suivi ce cursus au sein de l’armée :</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Cyber, un combat virtuel bien réel (#JDEF)\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/HM_XUsLbNvo?start=885&feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Des travaux pratiques sont également donnés par des employeurs militaires et civils, ce qui vous permettra d’être bien dans le bain avec la réalité du terrain et en fin de première année, vous effectuerez 5 semaines de stage au Ministère des Armées, histoire de parfaire encore plus votre formation en vous confrontant aux réalités du métier.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/bts4-prof-1024x576.webp\" alt=\"\" class=\"wp-image-132527\" srcset=\"https://korben.info/app/uploads/2023/01/bts4-prof-1024x576.webp 1024w, https://korben.info/app/uploads/2023/01/bts4-prof-300x169.webp 300w, https://korben.info/app/uploads/2023/01/bts4-prof-768x432.webp 768w, https://korben.info/app/uploads/2023/01/bts4-prof.webp 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Ce qui est cool également avec cette formation, c’est que tout est teinté cybersécurité, y compris les cours plus traditionnels d’informatique, et que les profs sont tous issus du monde professionnel, avec pour certains, une expérience dans le secteur de la défense. Donc si vous aimez la cybersécurité et votre pays, je pense que c’est une voie intéressante à envisager, avec tous les avantages d’une carrière militaire (qui a dit la retraite ? );-))</p>\n\n\n\n<p>Si ça vous chauffe, vous pouvez faire votre demande <a href=\"https://me.korben.info/hyn-bts-stcyr-parcoursup\" target=\"_blank\" rel=\"noreferrer noopener\">sur <strong>ParcourSup</strong> en cliquant ici</a>.

Tout d’abord, j’en peux plus de ces fake news, de ces ramassis de conneries et de tout ce que les assombris du bocal relaient toute la journée sur leurs réseaux sociaux ou sur des médias douteux. </p>\n\n\n\n<p>Je pense vraiment qu’on devrait faire fermer tous ces sites qui font la promotion de ces fausses informations tant cela fait des dégâts dans notre société. Et également, dans le respect et avec beaucoup de tendresse, écarteler les gens qui relaient ces fake news.</p>\n\n\n\n<p>Si je trouve ça bien que Google mette ce genre de chose en avant, c’est parce qu’il faut se rendre à l’évidence : La plupart des gens sont de grosses feignasses quand il s’agit de vérifier une information.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-888526240\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Par manque de temps bien sûr, et parce qu’à l’école, on ne leur a jamais vraiment appris à faire preuve d’esprit critique ou à aller au-delà de ce qu’on peut lire. Et même si je me souviens avoir appris à décomposer un article de presse, je n’ai jamais dans le cadre scolaire, appris à comprendre et analyser une information ou à déterminer la fiabilité d’un relai d’information.</p>\n\n\n\n<p>Ainsi, dans la tête de la plupart d’entre nous, un article sur FranceTV Info, sur JeanMarcMorandini, sur FranceSoir, ou encore sur une page Facebook quelconque, a la même valeur, la même crédibilité car : « Vue sur Internet ».</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/conspi-734x1024.jpg\" alt=\"\" class=\"wp-image-132152\" width=\"611\" height=\"852\" srcset=\"https://korben.info/app/uploads/2023/01/conspi-734x1024.jpg 734w, https://korben.info/app/uploads/2023/01/conspi-215x300.jpg 215w, https://korben.info/app/uploads/2023/01/conspi-768x1071.jpg 768w, https://korben.info/app/uploads/2023/01/conspi.jpg 1004w\" sizes=\"(max-width: 611px) 100vw, 611px\" /></figure></div>\n\n\n<p>Donc comme les gens sont ce qu’ils sont, et qu’on ne va pas se transformer en debunkeur du jour au lendemain, encore moins en croisant des sources, c’est plutôt cool qu’on mette ce genre d’information directement sous le nez de tout le monde.</p>\n\n\n\n<p>Je tiens d’ailleurs à saluer les journalistes qui font, contre vents et marées, ce travail abominable de fact checking qui consiste dans la plupart des cas, à rappeler des évidences scientifiques en le sourçant pour se faire ensuite insulter sur Twitter par des centaines d’abrutis.</p>\n\n\n\n<p>Alors même si je sais que les esprits les plus stupides proclament à longueur de journée que « <em>EUX, font leurs propres recherches</em> » et que l’ouverture de leur bouche est inversement proportionnelle à leur ouverture d’esprit, la vérité, c’est qu’ils cherchent que dalle et se contentent de répéter bêtement les âneries de leurs influenceurs hyper-stars (je vous laisse deviner lesquels).</p>\n\n\n\n<p>Alors pour ceux qui peuvent encore être un peu sauvés, car pas dans la croyance, et qui se posent effectivement des questions, j’ai ce qu’il vous faut.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1191227137\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Grâce à Google, vous allez pouvoir vérifier si toutes les « informations » que Tata Corinne ou votre collègue Thierry relaient sur Facebook / Twitter / TikTok sont fondées.

Cela implique donc par exemple <a href=\"https://korben.info/data-brokers-incogni.html\" data-type=\"URL\" data-id=\"https://korben.info/data-brokers-incogni.html\">les data brokers</a> dont j’ai déjà parlé sur ce site.</p>\n\n\n\n<p>Pour résumer, les data brokers vont récupérer vos informations personnelles (depuis différents services et base de données) et essayer de les croiser pour obtenir une fiche la plus complète possible à votre propos. De l’adresse mail, à l’adresse physique en passant par vos mots de passe ou vos données bancaires. Cela dans le but de les revendre à prix d’or à des démarcheurs ou d’autres organismes. Selon le data broker cette recherche va aller de simplement récupérer des informations légales (que vous avez données à divers services/sites) jusqu’à l’illégalité pure et simple (hack de base de données, etc.). Bref le panel est large et croyez-moi, VOS infos sont chez des dizaines d’entre eux (voir mon <a href=\"https://korben.info/incogni-test.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-test.html\">test personnel d’Incogni</a>).</p>\n\n\n\n<p>Ce sont ces revendeurs et ces acheteurs qui sont entrés un peu plus dans le collimateur de la CNIL depuis début de l’an dernier. Avec un rappel prononcé de leurs obligations en décembre 2022. Ce qu’il faut savoir c’est que ce genre de pratique n’est PAS interdite par le RGPD, ce n’est donc pas aussi simple que de dire qu’il faut tous les épingler, il existe une marge de manoeuvre.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"360\" decoding=\"async\" src=\"https://me.korben.info/b96-incognicnil-trk\" alt=\"\"/></figure></div>\n\n\n<p>La première chose qui leur est demandée est justement de<strong> s’assurer de la légalité des données</strong>. Notamment qu’elles ont bien été récoltées avec l’accord de la personne. Dans la majorité des cas ce sera que la personne a bien validé ou coché la case des conditions générales & Co lorsqu’elle s’est inscrite ou qu’elle a rempli un formulaire. Pour ceux qui refusent ces transmissions de données dès l’inscription, cela ne doit bien entendu jamais se retrouver chez un data broker, et encore moins être revendu par ce dernier. </p>\n\n\n\n<p>Le second point c’est que <strong>les données ne soient pas conservées plus longtemps que ne le demande la CNIL</strong>. À savoir 3 ans après la fin de l’acte qui a généré la relation commerciale (que ce soit l’achat sur un site e-commerce, la délivrance d’une prestation diverse, la fin d’une garantie …). De plus, tout ce qui a trait à la gestion d’un contentieux, à la comptabilité, etc. (bref toute la paperasse administrative) doit être exclu par défaut et ne pas être partagé.</p>\n\n\n\n<p>Là où le règlement de la CNIL va plus loin, c’est dans le fait que les acquéreurs des données doivent eux aussi s’assurer que tout est légal. Et nous en informer (dans un délai d’un mois), en citant leur source, si ce n’est pas le cas. Nous dire à qui ils ont acheté nos informations en somme et nous demander notre accord. Et ça, c’est plutôt cool parce que ça permet de savoir où nos infos ont trainé.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"320\" decoding=\"async\" src=\"https://media.giphy.com/media/WmjRRRrcUgb1WXM24M/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Ils doivent pouvoir prouver que nous avons donné notre consentement pour tout démarchage. C’est parfois inscrit de manière explicite dans les conditions générales ou les formulaires que nous validons en créant un compte quelconque. En vous inscrivant sur WhatsApp, vos données sont partagées avec Facebook & Co. Ce genre de choses. Dans le cas inverse à lui de recueillir votre assentiment. Et si vous n’êtes pas d’accord, il doit respecter votre demande de retrait/modification de sa liste.</p>\n\n\n\n<p>Bref, ça, c’est la théorie. Pas toujours simple à faire respecter ou difficile à gérer au cas par cas. Comment vraiment savoir qui a quoi ? À qui avez-vous donné les droits de partage sur tel site en 2017 ? Etc. Si vous préférez déléguer ou prendre les devants, <a rel=\"noreferrer noopener\" href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\">il y a Incogni</a>.</p>\n\n\n\n<p>Comme je l’ai déjà expliqué dans d’autres articles, le job d’Incogni va être proactif, avant même que les sociétés aient à vous contacter. Vous lui indiquez les données que vous acceptez de partager et celles que vous ne voulez plus voir sur le web et il va faire le taf à votre place.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"500\" height=\"281\" decoding=\"async\" src=\"https://media.giphy.com/media/vN3fMMSAmVwoo/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Il commencera par analyser le contenu de ce que possèdent des dizaines de data brokers sur vous. Et ensuite il les contactera pour leur demander de supprimer ce qui ne vous convient pas. De cette manière les acheteurs n’auront déjà plus accès à ces informations lorsqu’ils vont acquérir une base de données.</p>\n\n\n\n<p>Et si les data brokers ne font pas le boulot ? Incogni va continuer à les harceler régulièrement. Et si cela ne suffit toujours pas ? Alors vous pourrez peut-être vous tourner vers la CNIL. Mais, pour 5-6€/mois, le service de Surfshark est plutôt pratique. J’ai pris quelques minutes pour mettre en place mon test et depuis ce sont des dizaines de brokers qui m’ont retiré de leurs listes. Et qui continuerons, car l’outil veille au grain pour le cas où ils me réintégreraient en scred.</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Testez Incogni !</a></h2>\n",

Et bien cela commence peu à peu à revenir à la normale, avec le rendez-vous tech annuel <strong>Master Dev France</strong> (ex meilleur Développeur de France qui a été lancé en 2013 pour la première fois), après une pause de 2 ans, crise sanitaire oblige).</p>\n\n\n\n<p>Cet évènement majeur propose notamment le plus grand concours de code en live (sans filet !) de l’Hexagone, ainsi que diverses conférences animées par des personnalités de la tech et en lien avec des sujets qui nous parlent à tous !</p>\n\n\n\n<p>Ce 9 mars 2023 marque donc la 8e édition et <strong><a href=\"http://bit.ly/3RrFwiX\" target=\"_blank\" rel=\"noopener\">vous pouvez vous y inscrire gratuitement</a></strong> !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"800\" height=\"284\" decoding=\"async\" src=\"https://me.korben.info/ler-MDF-trk\" alt=\"Master Dev France 2023\"/></figure></div>\n\n\n<p>Si vous n’avez jamais participé à l’une des précédentes éditions, et que vous ne savez pas trop à quoi vous attendre, vous pourrez y retrouver un tas d’activités différentes. Il y a bien sûr la partie salon ainsi que de nombreuses animations qui prendront une place conséquente au bâtiment de la Porte de Versailles.</p>\n\n\n\n<p>Vous allez pouvoir y retrouver plusieurs dizaines d’entreprises (grands groupes français, associations majeures du numérique …), des écoles de la tech, des éditeurs… qui présenteront leur travail et/ou vous feront participer à divers workshops, etc. Sans oublier les médias qui vont se faire le plaisir de relayer l’évènement ! Bref vous allez pouvoir mettre les mains dans le cambouis et faire un truc assez fou : discuter avec de vraies gens et leur poser des questions. </p>\n\n\n\n<p>Et en spécial bonus, <strong>Master Dev France offrira un NFT</strong> réalisé par l’artiste Léo Caillard à chaque visiteur de l’événement ! Les visiteurs pourront collecter des NFTs auprès des partenaires de l’événement via des QR codes disposés à l’entrée et sur leurs stands. Partenaire de la Talent Fair, évènement RH dédié aux développeurs et recruteurs du Web3, Master Dev France offrira à ses visiteurs une expérience unique : la fusion de son NFT avec celui de la « Talent Fair » de la Paris Blockchain Week. Une première mondiale dans le cadre d’un événement professionnel ! </p>\n\n\n\n<p>Le programme prévoit <strong>une bonne vingtaine de conférences</strong> sur des sujets tech d’actualité, notamment le <strong>Web3</strong> (et l’Internet décentralisé au sens large), l’<strong>Intelligence Artificielle</strong>, les applications quantiques du futur…Du coup ce sera l’occasion d’avoir de bonnes introductions pour ceux qui voudraient en apprendre plus sur le métavers, la blockchain, le hack éthique, la cybersécurité, la régulation dans la crypto, l’éthique autour de l’IA, les algorithmes, l’inclusion numérique etc. En fin de journée, il y aura même un concert gratuit ! Ne mangez pas trop à midi, il faudra être en forme 😉</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"270\" decoding=\"async\" src=\"https://media.giphy.com/media/xPEQktRd4wa15ppQwq/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>En parallèle de ces conférences (et c’est ce qui fait battre mon petit cœur un peu plus fort), il y aura <strong>un gros concours pour les développeurs et développeuses</strong>. Le choix des armes sera assez vaste puisque chacun pourra choisir son langage préféré parmi une liste de 15 (PHP, Python, Java, C++ …). 2000 participants de toute l’Europe sont attendus pour ce concours de code live qui offrira 3 très beaux challenges algorithmiques et des prix plutôt sympas. </p>\n\n\n\n<p>Plus de 30 000€ sont à se répartir entre les meilleurs. Il y aura même une récompense pour celui ou celle qui codera de la manière la plus écoresponsable. 7 sessions qualificatives (sélection des 25 meilleurs de chaque) + la finale qui formeront une sorte de fil rouge de la journée.</p>\n\n\n\n<p>Vous êtes dev et vous voulez participer ? Il est encore temps <strong><a href=\"https://www.masterdevfrance.com/concours/?utm_campaign=MDF&utm_source=website&utm_medium=influence&utm_content=korben\" target=\"_blank\" rel=\"noopener\">de vous inscrire via ce formulaire</a></strong>. Et si c’est l’un d’entre vous qui l’emporte je veux <s>30% des gains</s> un « merci tonton Korben » sur scène lors de la remise du prix :p</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"266\" decoding=\"async\" src=\"https://media.giphy.com/media/h8ZRNWU2CDeA48fCYi/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Sur place vous allez pouvoir jongler entre conférences et sessions de code live tout au long de la journée. Ce genre d’évent c’est souvent assez sport pour faire tout ce qui nous intéresse donc pensez à planifier un peu. Tout en sachant que votre planning va tomber à l’eau une fois sur place parce que vous vous serez laissé entrainer par un truc ou l’autre. En tous cas c’est toujours ce qu’il m’arrive 😉</p>\n\n\n\n<p>Une autre ambition de Master Dev France est de mettre en lumière la place des femmes dans le milieu du dev et de la tech. Eh oui, notre monde professionnel est encore trop souvent perçu comme un milieu où elles n’ont pas toute la présence qu’elles méritent. Cela se traduit notamment par une équipe 100% féminine pour le concours de code et la présence de nombreuses intervenantes expertes de leurs sujets !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"750\" height=\"414\" src=\"https://korben.info/app/uploads/2023/01/salon-mdf-2023.jpg\" alt=\"\" class=\"wp-image-132556\" srcset=\"https://korben.info/app/uploads/2023/01/salon-mdf-2023.jpg 750w, https://korben.info/app/uploads/2023/01/salon-mdf-2023-300x166.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></figure></div>\n\n\n<p>La journée (qui attend 5000 visiteurs) est organisée par <a href=\"https://www.docaposte.com/\" target=\"_blank\" rel=\"noopener\">Docaposte</a>, la filiale numérique de La Poste, experte dans le traitement de la data et des données sensibles en particulier (comme les signatures électroniques, l’hébergement des dossiers médicaux, l’archivage numérique ou tout ce qui touche à l’identité numérique…).</p>\n\n\n\n<p>En tous cas ça fait du bien de revoir ce genre de salons et de conférences de manière régulière dans un monde post-pandémie ! Des tas de devs et de geeks vont enfin pouvoir retrouver un semblant de vie sociale, quelques jours chaque année 😉</p>\n\n\n\n<p>L’évènement se tiendra le jeudi 9 mars 2023 au Parc des Expositions de Paris, Porte de Versailles – Hall 5.2.</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"http://bit.ly/3RrFwiX\" target=\"_blank\" rel=\"noopener\">Inscrivez-vous gratuitement au Master Dev France 2023 !</a></h2>\n",

Une fois l’adaptateur réseau sélectionné, vous verrez des graphiques (rafraichis en temps réel) présentant la quantité de paquets et d’octets transitant par seconde.</p>\n\n\n\n<p>Vous pourrez alors classer ça par quantité de paquets, par quantités d’octets ou par fraicheur de la connexion :-). </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"977\" height=\"768\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230112-d6k.webp\" alt=\"\" class=\"wp-image-132138\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230112-d6k.webp 977w, https://korben.info/app/uploads/2023/01/SCR-20230112-d6k-300x236.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230112-d6k-768x604.webp 768w\" sizes=\"(max-width: 977px) 100vw, 977px\" /></figure></div>\n\n\n<p> Les paquets seront alors filtrés par protocole (HTTP, DNS, HTTPS, DHCP…etc.) et vous pouvez dès le lancement de l’application, choisir justement le protocole que vous voulez observer. Par contre, vous ne verrez pas le contenu de ces paquets comme on pourrait le faire avec un Wireshark. Sniffnet permet simplement de faire des statistiques et vous pourrez même exporter un rapport au format TXT qui contiendra toutes les informations suivantes : </p>\n\n\n\n<ul>\n<li>Adresses IP source et destination</li>\n\n\n\n<li>Ports source et destination</li>\n\n\n\n<li>Protocoles transportés</li>\n\n\n\n<li>Nombre de paquets et d’octets échangés</li>\n\n\n\n<li>Timestamp initial et final de l’échange d’informations</li>\n</ul>\n\n\n\n<p>Si comme moi, vous ne trouvez pas le bouton d’export, il se situe en bas à droite, mais pour le voir, il vous faudra agrandir la fenêtre au maximum.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1885140670\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Sinon, ça vous intéresse ? </p>\n\n\n\n<p>Alors pour commencer, il vous faut Rust à installer comme ceci sous macOS et Linux (pour Windows, <a href=\"https://forge.rust-lang.org/infra/other-installation-methods.html#rustup\" target=\"_blank\" rel=\"noopener\">cliquez ici</a>) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh</code></pre>\n\n\n\n<p>Ouvrez ensuite un nouveau terminal, pour recharger votre Shell et entrez la commande suivante pour installer Sniffnet : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>cargo install sniffnet</code></pre>\n\n\n\n<p>La bestiole va alors s’installer et vous permettre d’un seul coup d’oeil de voir l’ensemble de votre trafic réseau.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2023/01/ezgif.com-gif-maker-3.gif\" alt=\"\" class=\"wp-image-132137\" width=\"630\" height=\"394\"/></figure></div>\n\n\n<p>J’ai bien aimé la fonction « affichage clair » / « affichage sombre » qui n’est ni plus ni moins qu’une inversion de couleur.

De plus, il est compatible avec toutes les implémentations de Ruby et dispose de nombreuses extensions prêtes à l’emploi (par exemple rubocop-rails, rubocop-rspec, rubocop-performance et rubocop-minitest). Enfin, il est également compatible avec de nombreux éditeurs/IDE et est utilisé par de nombreux services en ligne tels que HoundCI, Sider et CodeClimate.</p>\n\n\n\n<p>Au niveau installation, rien de complexe. Vous pouvez l’installer en utilisant la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-preformatted\"><code>gem install rubocop</code></pre>\n\n\n\n<p>Si vous préférez utiliser Bundler, il suffit d’ajouter une ligne pour RuboCop dans votre Gemfile (en mettant, l’option <code>require</code> à <code>false</code>, puisque c’est un outil autonome) :</p>\n\n\n\n<pre class=\"wp-block-preformatted\"><code>gem 'rubocop', require: false</code></pre>\n\n\n\n<p>RuboCop, est conçu pour rester stable dans ses versions mineures, que ce soit en termes d’API ou de configuration des règles. Vous pouvez donc l’utiliser en toute confiance sans vous inquiéter de possibles ruptures de compatibilité.</p>\n\n\n\n<p>Pour l’utiliser, il vous suffit alors de lancer la commande suivante directement dans le dossier de votre projet ruby :</p>\n\n\n\n<pre class=\"wp-block-preformatted\"><code>rubocop</code></pre>\n\n\n\n<p>Et voilà ! </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1174894965\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>RuboCop va parcourir votre code et vous signaler tous les problèmes qu’il a trouvés.

Il est également disponible avec la commande curlconverter que vous pouvez installer sur votre machine.</p>\n\n\n\n<p>Par exemple, cette commande curl d’authentification : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>curl \"https://example.com/\" -u \"some_username:some_password\"</code></pre>\n\n\n\n<p>Devient en DART le code suivant : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>import 'dart:convert';\nimport 'package:http/http.dart' as http;\n\nvoid main() async {\n var uname = 'some_username';\n var pword = 'some_password';\n var authn = 'Basic ' + base64Encode(utf8.encode('$uname:$pword'));\n\n var url = Uri.parse('https://example.com/');\n var res = await http.get(url, headers: {'Authorization': authn});\n if (res.statusCode != 200) throw Exception('http.get error: statusCode= ${res.statusCode}');\n print(res.body);\n}</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1086223493\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Ou en C# : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>HttpClient client = new HttpClient();\n\nHttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, \"https://example.com/\");\n\nrequest.Headers.Add(\"Authorization\", \"Basic \" + Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(\"some_username:some_password\")));\n\nHttpResponseMessage response = await client.SendAsync(request);\nresponse.EnsureSuccessStatusCode();\nstring responseBody = await response.Content.ReadAsStringAsync();</code></pre>\n\n\n\n<p>CurlConverter sait interpréter la syntaxe Bash, tels que les chaînes de caractères ANSI-C et les fichiers pipés. Il connaît également tous les arguments de curl (il y en a plus de 300 !!), y compris ceux qui ont été supprimés des versions récentes (et donc ignorés la plupart du temps). Il peut également convertir les données JSON en objets natifs et génère le code capable de le lire soit à partir d’un fichier ou d’un flux en entrée.</p>\n\n\n\n<p>Malheureusement, seul le protocole HTTP est pris en charge, et les générateurs de code pour d’autres langages sont moins complets que le générateur pour Python. </p>\n\n\n\n<p>Pour utiliser <a href=\"https://curlconverter.com/\" target=\"_blank\" rel=\"noopener\">curlconverter</a>, vous pouvez l’installer en tant que bibliothèque JavaScript avec la commande </p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>npm install curlconverter</code></code></pre>\n\n\n\n<p>Ou comme outil utilisable en ligne de commande comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>npm install --global curlconverter</code></code></pre>\n\n\n\n<p>Voici un exemple de code généré à partir de cette commande :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>$ curlconverter --data \"hello=world\" example.com\nimport requests\n\ndata = {\n 'hello': 'world',\n}\n\nresponse = requests.post('http://example.com', data=data)</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1758613486\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Bref, super pratique pour ceux qui veulent se simplifier le processus de création de requêtes HTTP dans leur langage favori, tout en se reposant sur des commandes curl plus familières.</p>\n",

On les développe ou on les utilise sans vraiment se poser de question sur leurs performances réelles. Et c’est dommage car en tant que développeur, vous aimeriez peut être mesurer le temps d’exécution d’un script shell pour savoir s’il est plus rapide qu’une version précédente. Ou pouvoir comparer la rapidité d’exécution de différents programmes afin de sélectionner le meilleur !</p>\n\n\n\n<p>Pas de souci, j’ai ce qu’il vous faut. Cela s’appelle <a href=\"https://github.com/sharkdp/hyperfine\" target=\"_blank\" rel=\"noopener\"><strong>Hyperfine</strong></a> et c’est un outil de benchmarking qui s’utilise en ligne de commande et qui permet de comparer les temps d’exécution de différents programmes.</p>\n\n\n\n<p>C’est très utile pour mesurer par exemple les performances des programmes qui effectuent beaucoup d’écritures et de lectures sur un disque afin de voir comment ils se comportent avec ou sans cache, ou sur un disque dur ou un SSD. </p>\n\n\n\n<p>Hyperfine dispose de nombreuses fonctionnalités pour vous aider à obtenir des résultats précis et fiables, notamment une analyse statistique sur plusieurs exécutions, la prise en charge de commandes shell arbitraires et un retour constant sur l’avancement du benchmark et les estimations en cours.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2718436\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Pour l’utiliser, vous pouvez par exemple faire un benchmark de n’importe quelle commande comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>hyperfine COMMANDE_A_EVALUER</code></pre>\n\n\n\n<p>Pour tester la commande <code>sleep</code> par exemple, on fera comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>hyperfine 'sleep 0.3'</code></pre>\n\n\n\n<p>Ainsi, par défaut, Hyperfine effectuera au moins 10 exécutions du programme et prendra sa mesure à chaque fois pendant 3 secondes pendant au moins 3 secondes. Notez que vous pouvez changer cette durée de test en utilisant l’option <code>-r</code> ou <code>--runs</code> et en spécifiant la durée derrière.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"754\" height=\"276\" src=\"https://korben.info/app/uploads/2023/01/68747470733a2f2f692e696d6775722e636f6d2f7a31394f5978452e676966.gif\" alt=\"\" class=\"wp-image-132051\"/></figure></div>\n\n\n<p>Si vous souhaitez comparer les temps d’exécution de différents programmes, vous pouvez également passer plusieurs commandes à Hyperfine. Ainsi pour pour comparer les temps d’exécution de <code>hexdump</code> et <code>xxd</code>, vous pouvez appeler hyperfine comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>hyperfine 'hexdump VOTRE_FICHIER' 'xxd VOTRE_FICHIER'</code></code></pre>\n\n\n\n<p>Par exemple si vous avez un doute sur les performances d’une nouvelle version d’un outils, Hyperfine peut vous aider à la comparer avec une version précédente.</p>\n\n\n\n<p>Hyperfine vous permet également de réaliser des benchmarks où un seul paramètre change à chaque exécutions. Ca permet de mesurer le comportement d’un programme en fonction des paramètres que vous lui faites digérer. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-746537889\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Au niveau des exports, c’es top puisque vous pouvez récupérer ensuite les résultats au format CSV, JSON, Markdown…etc afin d’analyser ensuite tout ça au calme.</p>\n\n\n\n<p>Bref, <a href=\"https://github.com/sharkdp/hyperfine\" target=\"_blank\" rel=\"noopener\">c’est un petit outil en ligne de commande</a> qui ne paye pas de mine mais qui vous sera d’une grande aide pour faire vos benchmarks et comparer le temps d’exécution de vos propres codes ou d’outils tiers.</p>\n\n\n\n<p>Amusez-vous bien !</p>\n",

Du coup pour contourner ce problème, Apple a développé l’émulateur Rosetta, qui permet d’exécuter les applications non compatibles (pour architecture Intel quoi…) sur cette architecture ARM. C’est cool, mais évidemment, c’est moins performant donc il vaut mieux choper une version native de vos outils pour Silicon.</p>\n\n\n\n<p>M’enfin, si je vous parle de ça, c’est parce que je passe ma vie dans le Terminal et parfois, certains outils fonctionnent mal également à cet endroit. J’avais trouvé un moyen de lancer un terminal.app en mode de compatibilité Rosetta, mais Apple a bloqué la possibilité de dupliquer l’application Terminal.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221218-imh-2.webp\" alt=\"\" class=\"wp-image-131966\" width=\"243\" height=\"530\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221218-imh-2.webp 344w, https://korben.info/app/uploads/2022/12/SCR-20221218-imh-2-138x300.webp 138w\" sizes=\"(max-width: 243px) 100vw, 243px\" /></figure></div>\n\n\n<p>Tant pis, j’ai trouvé une autre solution que je vous présente et qui est assez simple. Cela se passe au niveau de votre fichier .zshrc. Pour rappel, ce fichier de configuration est utilisé par le shell ZSH sur les systèmes d’exploitation Unix / Linux, et donc macOS. </p>\n\n\n\n<p>Il est consulté à chaque fois que ZSH est lancé et permet de personnaliser les paramètres et les comportements de ZSH selon vos préférences. Cela permet par exemple de changer le look de l’interface de commande, d’ajouter des alias ou encore des chemins d’accès. Si vous n’avez pas de Shell ZSH sur votre macOS, vous pouvez l’activer par défaut en lançant un terminal et en tapant cette ligne de commande : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>chsh -s /bin/zsh</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1640447358\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Nous aujourd’hui, on va ajouter ces fameux alias pour pouvoir avoir un terminal compatible ARM ou INTEL à la demande. Ouvrez à nouveau un terminal sur votre Mac, et lancez la commande suivante pour ouvrir le fichier de config : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>nano ~/.zshrc</code></pre>\n\n\n\n<p>Ajoutez ensuite les 2 alias suivants dans le fichier, à la fin de celui-ci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>alias arm=\"env /usr/bin/arch -arm64 /bin/zsh --login\"\nalias intel=\"env /usr/bin/arch -x86_64 /bin/zsh --login\"</code></pre>\n\n\n\n<p>Comme vous pouvez le voir, je crée donc 2 alias : arm et intel qui vont permettre de changer l’architecture utilisée par votre terminal zsh. C’est aussi simple que cela. Voici ce que ça donne :</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221218-gmr.webp\" alt=\"\" class=\"wp-image-131967\" width=\"615\" height=\"435\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221218-gmr.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221218-gmr-300x212.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221218-gmr-768x544.webp 768w\" sizes=\"(max-width: 615px) 100vw, 615px\" /></figure></div>\n\n\n<p>Sauvegardez et quittez (CTRL+O puis CTRL+X). Et relancez votre terminal.</p>\n\n\n\n<p>Maintenant, vous n’avez plus qu’à taper la commande « intel » pour basculer sur une architecture x86_64 et à taper « arm » pour revenir à une architecture arm64. Et pour vérifier le type d’architecture sur laquelle vous êtes, utilisez simplement la commande :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>arch</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221218-gmz.webp\" alt=\"\" class=\"wp-image-131968\" width=\"590\" height=\"417\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221218-gmz.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221218-gmz-300x212.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221218-gmz-768x544.webp 768w\" sizes=\"(max-width: 590px) 100vw, 590px\" /></figure></div>\n\n\n<p>Ça reste une bidouille pour contourner une limite débile imposée par Apple, mais j’espère que ça vous aidera.</p>\n",

Par exemple, en 1908, un astéroïde est tombé en Sibérie, à Tunguska en Russie, causant une onde de choc qui a dévasté une région de 2 000 km2. Les scientifiques (et Fox Mulder) estiment que l’astéroïde avait une taille d’environ 40 m de diamètre et qu’il voyageait à environ 15 km/s lors de l’impact. Cet astéroïde est tombé dans une zone peu peuplée, ce qui a limité le nombre de victimes… Heureusement.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"574\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221218-fao.webp\" alt=\"\" class=\"wp-image-131959\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221218-fao.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221218-fao-300x172.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221218-fao-768x441.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"578\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221218-fas.webp\" alt=\"\" class=\"wp-image-131960\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221218-fas.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221218-fas-300x173.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221218-fas-768x444.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1544034974\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Impressionnant non ? Bon, là j’ai un peu abusé avec un astéroïde de 1,5 km de large tombant sur Clermont-Ferrand, mais c’est pour les besoins de la démo. Mais ce site donne une estimation des dégâts, des morts, le rayon de l’impact et le compare même avec d’autres événements de ce genre qui auraient pu se produire.</p>\n\n\n\n<p>Rassurez-vous, ce que je viens de simuler arrive en moyenne tous les 20 millions d’années. Donc ça peut être ce soir ou dans 10 millions d’années, on ne peut pas y faire grand-chose. L’avantage c’est qu’on aurait surement un jour de congé le lendemain ;-))</p>\n\n\n\n<p>Selon les estimations, il y a environ 1 million d’astéroïdes de taille supérieure à 1 km de diamètre qui se baladent dans le système solaire et qui seraient une menace potentielle pour la Terre. Mais seulement 20 000 d’entre eux ont été détectés et sont étudiés à ce jour… gloups.</p>\n\n\n\n<p>Et si vous aimez les catastrophes plus nucléaires, <a href=\"https://korben.info/bombe-nucleaire-quels-degats-chez-vous.html\">ça se passe par ici</a>.</p>\n\n\n\n<p>Merci à Letsar pour le partage !</p>\n",

Je suis d’ailleurs très content de ma dernière vidéo dans laquelle j’explique <a href=\"https://www.patreon.com/posts/comment-coder-3-77496122\" target=\"_blank\" rel=\"noopener\">comment automatiser la création d’une newsletter qui tire son contenu d’un WordPress et l’améliore avec GPT-3</a> pour en faire quelque chose d’agréable à lire et de différent à chaque fois.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1912507680\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>J’ai également (comme tout le monde) commencé la série The Last of Us et franchement, ça paaaaasssse. Les zombies sont bien dégueu quand même et je comprends mieux l’objectif à long terme des champignons de Paris de prendre la capitale. Je suis retourné également au cinéma pour la dernière fois de ma vie, je pense, tant certains humains qui fréquentent les salles obscures font tout pour gâcher le plaisir des autres. J’ai donc vu Avatar 2. C’était bien, mais trop long et trop d’eau partout. Je crois que j’en ai encore dans les poumons.</p>\n\n\n\n<p>Sinon, bah toujours en mode bricole dans la maison. J’ai encore de l’enduit à faire, une chatière à poser, un poêle à bois à domotiser et quelques arbres arrachés avec la tempête à débiter. C’est du taf ! J’ai également commencé à regarder les presses à pellets et je ne sais pas encore si c’est un bon investissement. Si vous pratiquez la fabrication de pellets, je veux bien un retour d’expérience et des conseils :). Puis je cuisine toujours autant ce qui me permet de faire des économies et de manger mieux. Je vous recommande l’expérience, surtout qu’avec <a href=\"https://korben.info/process-repas-charge-mentale.html\">Jow</a>, ça me prend aucun temps.</p>\n\n\n\n<p>Voilà pour les news. Et vous ?</p>\n\n\n\n<p>À bientôt sur les réseaux et n’oubliez pas qu’on peut également se retrouver en live <a href=\"https://twitch.tv/korbenFR\" target=\"_blank\" rel=\"noopener\">sur Twitch !!</a></p>\n",

Et oui, le format Excel est une saloperie, mais c’est très utilisé donc il faut composer avec notamment dans le monde professionnel.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/base.webp\" alt=\"\" class=\"wp-image-131922\" width=\"678\" height=\"431\" srcset=\"https://korben.info/app/uploads/2022/12/base.webp 1000w, https://korben.info/app/uploads/2022/12/base-300x191.webp 300w, https://korben.info/app/uploads/2022/12/base-768x488.webp 768w\" sizes=\"(max-width: 678px) 100vw, 678px\" /></figure></div>\n\n\n<p>Pour l’installer, il vous suffit d’ouvrir un terminal et de taper la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>go install github.com/xuri/excelize@latest</code></pre>\n\n\n\n<p>Une fois installée, vous pourrez alors utiliser Excelize pour créer de nouveaux fichiers Excel ou pour lire des fichiers existants. Voici un exemple de code pour illustrer la création d’un nouveau fichier Excel et ajouter une feuille de calcul et une valeur à cette feuille. </p>\n\n\n\n<pre class=\"wp-block-code\"><code>package main\n\nimport (\n \"fmt\"\n\n \"github.com/xuri/excelize/v2\"\n)\n\nfunc main() {\n f := excelize.NewFile()\n // Créer une nouvelle feuille.\n index := f.NewSheet(\"Sheet2\")\n // Définir la valeur d'une cellule.\n f.SetCellValue(\"Sheet2\", \"A2\", \"Hello world.\")\n f.SetCellValue(\"Sheet1\", \"B2\", 100)\n // Définir la feuille active du classeur.\n f.SetActiveSheet(index)\n // Enregistrer le fichier xlsx par le chemin donné.\n if err := f.SaveAs(\"Book1.xlsx\"); err != nil {\n fmt.Println(err)\n }\n}</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-100380283\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Easyyyy ! </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/grid_0-2-1.webp\" alt=\"\" class=\"wp-image-131924\" width=\"781\" height=\"521\" srcset=\"https://korben.info/app/uploads/2022/12/grid_0-2-1.webp 1000w, https://korben.info/app/uploads/2022/12/grid_0-2-1-300x200.webp 300w, https://korben.info/app/uploads/2022/12/grid_0-2-1-768x512.webp 768w\" sizes=\"(max-width: 781px) 100vw, 781px\" /></figure></div>\n\n\n<p>Ensuite, pour lire un fichier Excel, vous pouvez utiliser la méthode « ReadFile » comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>package main\n\nimport (\n \"fmt\"\n\n \"github.com/xuri/excelize/v2\"\n)\n\nfunc main() {\n f, err := excelize.OpenFile(\"Book1.xlsx\")\n if err != nil {\n fmt.Println(err)\n return\n }\n defer func() {\n if err := f.Close(); err != nil {\n fmt.Println(err)\n }\n }()\n // Obtenir la valeur de la cellule par nom de feuille de calcul donné et axe.\n cell, err := f.GetCellValue(\"Sheet1\", \"B2\")\n if err != nil {\n fmt.Println(err)\n return\n }\n fmt.Println(cell)\n // Obtenez toutes les lignes de la feuille Sheet1.\n rows, err := f.GetRows(\"Sheet1\")\n if err != nil {\n fmt.Println(err)\n return\n }\n for _, row := range rows {\n for _, colCell := range row {\n fmt.Print(colCell, \"\\t\")\n }\n fmt.Println()\n }\n}</code></pre>\n\n\n\n<p><a href=\"https://xuri.me/excelize/\" target=\"_blank\" rel=\"noopener\">Pratique non ?</a></p>\n",

L’outil s’utilise en ligne de commande, mais vous pouvez aussi lui donner un fichier de config à digérer pour qu’il fasse exactement ce que vous voulez à partir de tous les paramètres spécifiés dans ce JSON. Comme je le disais en intro, c’est également un framework, vous vous pouvez utiliser son API JavaScript qui est encore plus flexible.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>import editly from 'editly';\n\n// See editSpec documentation\nawait editly(editSpec)</code></pre>\n\n\n\n<p>Totalement inspiré de ffmpeg-concat, Editly est beaucoup plus rapide et ne nécessite pas énormément d’espace de stockage, car il édite la vidéo à la volée. On peut également étendre ses fonctionnalités avec des modules si besoin.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"320\" height=\"180\" src=\"https://korben.info/app/uploads/2022/12/resizeHorizontal.gif\" alt=\"\" class=\"wp-image-131906\"/></figure></div>\n\n\n<p>En termes de fonctionnalités, il permet d’éditer des vidéos, d’en créer « from scratch » à partir de couleurs et d’effets aléatoirement générés et il prend en charge de toutes les résolutions comme des vidéos 4K ou des photos DSLR. Au niveau des exports, c’est pareil, il peut aussi bien pondre un post Instagram (1:1), une story Instagram (9:16), un format pour YouTube (16:9) ou toutes les autres dimensions dont vous avez besoin. C’est vraiment un outil génial pour les créateurs qui font de la vidéo et qui ont besoin de sortir un même contenu sur plusieurs plateformes qui acceptent des formats et des tailles de vidéos différentes.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1763237998\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Voici un rendu d’une vidéo produite avec Editly : </p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"This video was created from code!

Il supporte également du JavaScript / HTML5 Canvas / Fabric.js pour tout ce qui est « écrans personnalisés » ou pour pouvoir ajouter des superpositions dynamiques sur les vidéos.</p>\n\n\n\n<p>Vous pourrez également exporter un GIF, ajouter des effets de vignette, conserver 1 seule source audio ou au contraire en mixer plusieurs, ou encore rajouter des fondus automatiques et de la normalisation sur le son.</p>\n\n\n\n<p>En ce qui concerne l’installation, cette merveille peut fonctionner sous Windows, macOS ou Linux.</p>\n\n\n\n<p>Pour l’installer, vous devez entrer la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>npm i -g editly</code></pre>\n\n\n\n<p>Une fois installé, vous pourrez alors utiliser l’interface en ligne de commande pour assembler rapidement une vidéo ou utiliser son API JavaScript pour créer des choses plus complexes. Et comme je l’évoquais avant, vous pouvez également utiliser des fichiers JSON pour spécifier les paramètres du montage attendu. Je vous invite à lire la documentation pour en savoir plus.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1143698013\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Ce mode de fonctionnement « automatisé » de l’édition vidéo va vous faire gagner un max de temps si vous souhaitez par exemple créer un diaporama à partir de dizaines d’images en rajoutant du texte par-dessus, ou encore créer une bande-annonce ou une vidéo promo. Certain font même <a href=\"https://www.youtube.com/channel/UCDUauYxuY5Cv1Z6AuD3UGDw?view_as=subscriber\" target=\"_blank\" rel=\"noopener\">des chaines YouTube</a> avec du contenus entièrement générés comme ça.</p>\n\n\n\n<p>Mais vous pouvez l’utiliser simplement pour recadrer automatiquement une vidéo pour l’avoir dans plusieurs formats, c’est également super pratique.</p>\n\n\n\n<p><a rel=\"noopener\" href=\"https://github.com/mifi/editly\" target=\"_blank\">Bref, j’ai trouvé ça génial et c’est à tester ici !</a></p>\n",

Cette société qui a l’ambition de changer le visage de la robotique en plaçant l’imaginaire au cœur de la technologie a donc pour objectif de créer des « robots-personnages » qui sont à la fois performants dans leur travail, mais qui offrent également une expérience inédite pour les personnes qui le croisent.</p>\n\n\n\n<p>Je ne savais vraiment pas ce que j’allais voir et la surprise a été très agréable. La société porte bien son nom, puisque lors de la présentation, Miroki n’a pas été présenté comme un robot purement fonctionnel, mais vraiment comme un personnage avec son univers, son histoire, etc. L’objectif étant, je pense, d’éviter l’effet Uncanny Valley bien connu des concepteurs de robots humanoïdes, qui est le malaise ressenti par les personnes en présence d’entités artificielles proches de l’apparence humaine, mais pas tout à fait identiques.</p>\n\n\n\n<p>Ce robot qui nous a donc été dévoilé s’appelle Miroki et il a été conçu et développé en moins d’un an (un record !!) par les ingénieurs d’Enchanted Tools. Pour la petite histoire, Miroki vient d’une planète lointaine baptisée Miroko et décide de débarquer sur Terre pour venir nous rencontrer.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Enchanted Tools — L'origine des Mirokaï (Version Française)\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/CVPKgBw4S7k?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Certains diront qu’il a été ensuite réduit en esclavage par les humains, mais je vous assure qu’il vient bosser de son plein gré ^^. Il a été conçu pour être utilisé dans des environnements impliquant des rencontres avec du public tels que les hôpitaux, les maisons de retraite, les aéroports, les salons professionnels, les hôtels ou encore les restaurants. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-92445969\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>L’objectif est donc de décharger les personnels de tâches logistiques fatigantes et leur permettre de se concentrer sur les soins, les relations humaines, leur vrai boulot quoi. Pour faire son « travail », Miroki est capable de saisir des objets à l’aide de poignées, tels quel des plateaux ou des chariots, puis de les emmener ailleurs en fonction de sa programmation. Dans un environnement hospitalier, on peut imaginer qu’il transporte du matériel ou des médicaments d’un endroit à un autre en fonction des besoins, mais aussi qu’il émerveille les enfants de passage à l’hôpital.</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Enchanted Tools — Miroki in Hospital\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/32pFtkOjBmQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>D’ailleurs, son système de déplacement sur une boule est vraiment ingénieux et même s’il ne monte pas les escaliers, il est tout à fait capable de naviguer automatiquement dans des espaces assez classiques.</p>\n\n\n\n<p>Et surtout, il est capable d’interagir avec des utilisateurs « non préparés » en discutant avec eux ou en comprenant leurs gestes. Il pourrait par exemple répondre à des questions de personnes qui cherchent leur chemin, voire même les accompagner. Il pourrait donner des renseignements ou appeler du personnel soignant en renfort en cas de besoin.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"574\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230117-dyy.webp\" alt=\"\" class=\"wp-image-132276\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230117-dyy.webp 1024w, https://korben.info/app/uploads/2023/01/SCR-20230117-dyy-300x168.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230117-dyy-768x431.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Au niveau des spécifications techniques, il mesure 1m23 pour 28kg, et dispose de 28 degrés de liberté, dont 22 avec contrôle d’impédance.

Par exemple, comme mentionné sur cette pages, avec cette lib, vous pouvez coder des outils pour faire des trucs très cool comme : </p>\n\n\n\n<ul>\n<li><strong>ArpSpoofing</strong>: une application qui utilise les fonctionnalités de Packet++ et Pcap++ pour effectuer du spoofing ARP.</li>\n\n\n\n<li><strong>Arping</strong>: une implémentation de l’utilitaire arping en utilisant PcapPlusPlus.</li>\n\n\n\n<li><strong>DnsSpoofing</strong>: un utilitaire en ligne de commande qui effectue du spoofing DNS en utilisant Packet++ et Pcap++.</li>\n\n\n\n<li><strong>DNSResolver</strong>: un utilitaire en ligne de commande qui résout les adresses IPv4 pour un nom d’hôte en utilisant les protocoles ARP et DNS.</li>\n\n\n\n<li><strong>IcmpFileTransfer</strong>: une application qui montre comment transférer des fichiers entre deux machines en utilisant uniquement des messages ICMP.</li>\n\n\n\n<li><strong>HttpAnalyzer</strong>: une application qui analyse le trafic HTTP et fournit des informations détaillées sur le trafic, comme le nombre et le taux de paquets, la bande passante, le nombre et le taux de flux, les requêtes et les réponses HTTP, l’histogramme des noms d’hôte, l’histogramme des types de contenu, l’histogramme des codes d’état et bien plus encore. Peut fonctionner sur du trafic en direct ou lire des paquets depuis un fichier pcap.</li>\n\n\n\n<li><strong>SSLAnalyzer</strong>: une application qui analyse le trafic SSL/TLS et fournit des informations détaillées sur le trafic, comme le nombre et le taux de paquets, la bande passante, le nombre et le taux de flux, le nombre de messages SSL/TLS, l’histogramme des noms d’hôte, le nombre de versions SSL/TLS, le nombre de suites de chiffrement et bien plus encore. Peut fonctionner sur du trafic en direct ou lire des paquets depuis un fichier pcap.</li>\n</ul>\n\n\n\n<p>Comme cette lib C++ est conçue pour être extrêmement rapide et légère, cela lui permet de traiter tous ces paquets très rapidement avec très peu de charge sur le système. Vous pourrez bien évidement l’utiliser sur votre OS, que ce soit du Windows, du MacOS, du Linux, de l’Android ou encore FreeBSD (les sources sont disponibles).</p>\n\n\n\n<p>Voici un exemple d’implémentation pour lire des paquets : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>// create a pcap file reader\npcpp::PcapFileReaderDevice pcapReader(\"input.pcap\");\npcapReader.open();\n\n// create a pcapng file writer\npcpp::PcapNgFileWriterDevice pcapNgWriter(\"output.pcapng\");\npcapNgWriter.open();\n\n// raw packet object\npcpp::RawPacket rawPacket;\n\n// read packets from pcap reader and write pcapng writer\nwhile (pcapReader->getNextPacket(rawPacket)) {\n pcapNgWriter.writePacket(rawPacket);\n}</code></pre>\n\n\n\n<p>Une interface graphique facile à utiliser permet également de lire et d’écrire ces fameuses trames réseau dans des fichiers, prenant ainsi en charge les formats de fichier PCAP et PCAPNG. De plus, il contient une implémentation unique de techniques de réassemblage de paquets, notamment le réassemblage TCP qui prend en charge la retransmission TCP, les paquets TCP hors ordre et les données TCP manquantes, ainsi que la fragmentation et le défragmentation IP pour créer et réassembler des fragments IPv4 et IPv6.</p>\n\n\n\n<p>Avec <a href=\"https://pcapplusplus.github.io/\" target=\"_blank\" rel=\"noopener\">PcapPlusPlus</a> vous pourrez également filtrer les paquets ou générer des empreintes numériques TLS pour cibler et identifier les paquets réseau de manière beaucoup plus précise.</p>\n\n\n\n<p>Bref, tout ça pour dire que si votre cafetière est connectée sur le réseau, PcapPlusPlus peut même faire le café !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-462214832\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Allez, pour installer ce truc, <a href=\"https://pcapplusplus.github.io/docs/quickstart\" target=\"_blank\" rel=\"noopener\">toute la doc est là !</a> Amusez vous bien !</p>\n",

Plus il y en a, plus elles sont personnelles et mieux c’est pour eux puisqu’il peuvent dresser un profil de plus en plus précis. Et ce qui permet d’avoir cette précision c’est souvent via le recoupement depuis plusieurs sources.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"626\" height=\"417\" decoding=\"async\" src=\"https://me.korben.info/i6u-incogni-enrichissement\" alt=\"\"/></figure></div>\n\n\n<p>Vous donnez vos nom, prénom et adresse mail pour télécharger un livre blanc sur un site marketing ? Vous avez un compte fidélité sur un site e-commerce de produits de santé spécifiques (asthme, maladie cardiaque …) et sur lequel vous êtes connecté avec le même email ? Vous répondez à un sondage sur les bienfaits du mariage? Vous avez une société pour laquelle nom, prénom, adresse & Co se trouvent sur des sites officiels publics ? Et bien en mixant toutes ces sources on obtient un profil assez complet de qui vous êtes via cette méthode de l’enrichissement de données. Ces différentes données peuvent être récupérées soit tout à fait légalement, soit <a href=\"https://korben.info/data-brokers-incogni.html\" data-type=\"URL\" data-id=\"https://korben.info/data-brokers-incogni.html\">via des data brokers</a>, des bases en vente au marché noir, des fuites de données, etc. </p>\n\n\n\n<p>Korben : adolescent autour de la quarantaine, multiples enfants, habite l’Élysée, achète en ligne (le plus souvent des produits écologiques et des frites surgelées), s’inquiète de sa tension artérielle et a téléchargé l’ebook « bien manger avec ses mains ». FLIPPANT DE PERTINENCE !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"264\" decoding=\"async\" src=\"https://media.giphy.com/media/bEVKYB487Lqxy/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Ce qu’il faut comprendre c’est que le plus souvent ce n’est pas fait de manière illégale par ceux qui proposent un produit ou un service. Chacun va vous demander les informations dont il a besoin pour satisfaire son offre, mieux cibler sa publicité ou générer sa liste d’abonnés, mais sans abuser non plus. Prenons l’exemple du livre blanc au format PDF, est-ce que vous le demanderiez si le site vous demandait votre adresse physique, votre situation familiale ou autre ? Bien sûr que non, vous l’enverriez sur les roses (avec raison). Idem si WhatsApp vous demandait de fournir un carnet de santé ou vos rémunérations mensuelles. Par contre les bases de données de ces sites ou la newsletter d’un blog peut avoir été hackées sans même que leurs créateurs ne soient au courant.</p>\n\n\n\n<p>D’autres services vous disent carrément qu’ils récolteront des données vous concernant via d’autres sites ou applis sur lesquelles vous êtes présents. Mais comme personne ne lit les petits caractères et que les termes employés sont volontairement vagues … ça passe. Des exemples ? Amazon, Facebook, Instagram, Google ou Twitter. En signant chez eux, vous leur donnez le droit d’aller chercher vos informations ailleurs (avec certaines limites et une anonymisation des données … normalement). Imaginez que vous ayez un profil tout ce qu’il y a de plus corporate sur Facebook et que vous utilisiez Twitter pour propager des conspirations platistes ou reptiliennes à longueur de journée de manière anonyme. Et que vous avez utilisé le même mail ou le même téléphone pour les 2. Juste, imaginez.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"500\" height=\"281\" decoding=\"async\" src=\"https://media.giphy.com/media/rr1DGz8pXZVHVDZyu6/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>LinkedIn est un bon exemple qui permet l’enrichissement de données. Vous vous inscrivez sur un site quelconque avec nom et prénom et la société derrière ce site peut aller faire une recherche LinkedIn pour enrichir votre profil avec votre poste, l’entreprise dans laquelle vous travaillez et autres infos. Ce qui va leur permettre d’affiner leur communication avec vous, voire d’aller vous relancer directement sur le réseau. Et d’autres sites ont pignon sur rue : Clearbit, Dropcontact, etc.</p>\n\n\n\n<p>Comme tout ce croisement d’informations se fait souvent de manière discrète dans l’arrière-boutique du web, vous pouvez vous brosser pour que la loi applique des sanctions ou fasse <a href=\"https://korben.info/incogni-rgpd.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-rgpd.html\">respecter vos droits RGPD</a>. Ou alors vraiment dans une faible mesure, trop tard ou dans des cas flagrants (<a href=\"https://korben.info/incogni-cpf.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-cpf.html\">arnaques liées au compte personnel de formation</a>). Une manière de prendre les choses en main et de minimiser les risques de manière proactive c’est avec Incogni et pour moins de 6€ par mois.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"626\" height=\"417\" src=\"https://korben.info/app/uploads/2023/01/vie-privee-internet.jpg\" alt=\"\" class=\"wp-image-132159\" srcset=\"https://korben.info/app/uploads/2023/01/vie-privee-internet.jpg 626w, https://korben.info/app/uploads/2023/01/vie-privee-internet-300x200.jpg 300w\" sizes=\"(max-width: 626px) 100vw, 626px\" /></figure></div>\n\n\n<p>Bien entendu la première étape c’est votre comportement personnel au quotidien : ne pas s’inscrire n’importe où et à n’importe quoi, ne pas le faire avec de vraies infos perso si ce n’est pas obligatoire, effacer ses données et supprimer ses comptes régulièrement, utiliser plusieurs boites mails/profils sociaux pour diluer les données, etc. Mais ce n’est pas toujours possible. Et dans ce cas il reste l’option de faire supprimer ce qui a déjà été récupéré sur vous. <a rel=\"noreferrer noopener\" href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\">C’est le job d’Incogni</a>.</p>\n\n\n\n<h2>Incogni comment ça marche ?</h2>\n\n\n\n<p>Lorsque vous créez votre compte chez eux, vous allez lister les données que vous voulez voir disparaitre auprès des différents data brokers. Le service va alors analyser ces derniers et voir s’ils disposent de ces informations que vous voulez retirer. Une fois qu’il vous aura donné la liste de ceux-ci, il va les contacter tous pour leur demander d’effacer toute trace de votre existence. Cela mettra parfois plusieurs semaines ou mois, mais ils vont les relancer jusqu’à ce que ce soit fait.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"800\" height=\"414\" src=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg\" alt=\"\" class=\"wp-image-130591\" srcset=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg 800w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-300x155.jpg 300w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-768x397.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" /></figure></div>\n\n\n<p>Cela ne vous prendra que quelques minutes à mettre en place et ensuite c’est Incogni qui va se charger de tout. Selon le site cela prendrait plus de 300 heures si vous deviez le faire à la main tout seul (j’imagine que c’est en considérant que vos données apparaitraient chez les quasi 150 brokers qu’ils surveillent).</p>\n\n\n\n<p>Personnellement c’est un service que j’utilise depuis plusieurs mois (voir <a href=\"https://korben.info/incogni-test.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-test.html\">mon test</a> de mise en place). Et chaque fois que je vois un data broker supplémentaire qui a accédé à la requête de suppression, j’ai une petite dose de bonheur qui se libère dans mon corps. Tu veux toi aussi avoir droit à ce bonheur ?</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Découvre Incogni !</a></h2>\n",

Cytopia utilise un moteur de rendu isométrique basé sur SDL2 et pour le moment, il sait générer des terrains de manière procédurale et propose tous les éléments de base de SimCity tels quel les routes, les quartiers (résidentiel, industriel, commerciaux et d’autres)…etc.</p>\n\n\n\n<p>Attention, on est encore loin de quelque chose de finalisé. C’est un travail en cours de développement.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"924\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221215-geg.webp\" alt=\"\" class=\"wp-image-131873\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221215-geg.webp 924w, https://korben.info/app/uploads/2022/12/SCR-20221215-geg-300x244.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221215-geg-768x623.webp 768w\" sizes=\"(max-width: 924px) 100vw, 924px\" /></figure></div>\n\n\n<p>Ce qui est intéressant avec Cytopia, c’est qu’il est en constante évolution. Les développeurs sont sans cesse en train de travailler sur de nouvelles fonctionnalités pour améliorer l’expérience de jeu. </p>\n\n\n\n<p>Par exemple, ils prévoient d’ajouter des biomes, ces grandes régions géographiques qui ont leur propre climat et leur propre faune et flore. Cela ajoutera une nouvelle dimension à la construction de vos villes, car vous devrez tenir compte des conditions climatiques et écologiques de chaque biome lorsque vous construirez vos quartiers et vos routes.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"924\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221215-gg9.webp\" alt=\"\" class=\"wp-image-131874\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221215-gg9.webp 924w, https://korben.info/app/uploads/2022/12/SCR-20221215-gg9-300x244.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221215-gg9-768x623.webp 768w\" sizes=\"(max-width: 924px) 100vw, 924px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1068580014\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Les développeurs travaillent également sur un mécanisme de téléchargement de mods directement dans le jeu. Vous pourrez ainsi facilement télécharger les mods créés par d’autres joueurs pour ajouter de nouvelles fonctionnalités, de nouvelles possibilités de constructions voire de nouveaux univers. </p>\n\n\n\n<p>Bientôt des villes sur Mars ? </p>\n\n\n\n<p>Et comme Cytopia est un jeu open source, vous pourrez évidemment créer vos propres mods perso si vous le souhaitez. Bien sûr, Cytopia ne néglige pas non plus l’aspect musical du jeu. Le jeu possède sa bande-son originale avec des bruits ambiants et des effets sonores qui sont tout simplement excellents. Vous vous sentirez vraiment immergé dans votre ville virtuelle rien qu’à vous.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"563\" src=\"https://korben.info/app/uploads/2022/12/jimmy2_2.webp\" alt=\"\" class=\"wp-image-131875\" srcset=\"https://korben.info/app/uploads/2022/12/jimmy2_2.webp 1000w, https://korben.info/app/uploads/2022/12/jimmy2_2-300x169.webp 300w, https://korben.info/app/uploads/2022/12/jimmy2_2-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Cytopia est disponible sur macOS, Linux et Windows, et il devrait également y avoir une version pour Android et iOS à l’avenir. Les développeurs travaillent également sur un langage de script similaire à du LUA pour faciliter la création de mods. Si vous êtes intéressé par le développement de Cytopia, vous pouvez retrouver <a href=\"https://github.com/CytopiaTeam/Cytopia\" target=\"_blank\" rel=\"noopener\">le code sur Github</a>.</p>\n\n\n\n<p>N’hésitez pas à essayer le jeu et à vous impliquer dans la communauté des joueurs et des développeurs si le coeur vous en dit !</p>\n",

Et comme Thor est disponible gratuitement dans l’App Store, vous pouvez l’essayer sans débourser un centime.</p>\n\n\n\n<p>En plus de simplifier l’ouverture des applications, Thor vous permet également de lancer des commandes spécifiques dans ces applications. Par exemple, vous pouvez configurer un raccourci pour ouvrir un nouveau document dans votre traitement de texte préféré, ou pour lancer une recherche sur internet dans votre navigateur. Cela vous permet d’accéder rapidement aux fonctionnalités que vous utilisez le plus souvent, sans avoir à naviguer dans les menus de l’application ou à utiliser des combinaisons de touches compliquées. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1377407415\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Par exemple pour lancer quelques scripts Python, c’est génial !</p>\n\n\n\n<p><a href=\"https://github.com/gbammc/Thor\" target=\"_blank\" rel=\"noopener\">À découvrir ici !</a></p>\n",

Hé oui.</p>\n\n\n\n<p>Il y a quelques semaine, <a href=\"https://korben.info/chatgpt-openai.html\"><strong>j’ai d’ailleurs écrit un article sur OpenAI</strong></a> qui a lancé un chatbot, basé sur son algo GPT-3, qui utilise de l’intelligence artificielle pour générer des réponses à des questions complexes. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-79307429\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Comme GPT-3, Andi est capable de fouiller des sources de contenus pour trouver les informations pertinentes et de les présenter de manière synthétique. Cependant, contrairement à Andi, qui se concentre sur les réponses aux questions, GPT-3 peut aussi générer du texte original sur un large éventail de sujets. En utilisant l’intelligence artificielle pour traiter les données, ces outils peuvent fournir des réponses plus précises et plus complètes que ce que nous serions capables de faire manuellement. C’est vraiment top !</p>\n\n\n\n<p>Andi peut ainsi répondre à des questions basiques comme « Quelle heure est-il ? » ou encore « Quelle est la capitale de l’Italie ?’ …</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221201-t57.webp\" alt=\"\" class=\"wp-image-131723\" width=\"283\" height=\"351\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221201-t57.webp 604w, https://korben.info/app/uploads/2022/12/SCR-20221201-t57-242x300.webp 242w\" sizes=\"(max-width: 283px) 100vw, 283px\" /></figure></div>\n\n\n<p>…ou des choses un peu plus complexes, sans aucune difficulté. Pour cela il sélectionne une liste de sources de contenus qui correspondent à votre demande et est capable de les analyser pour en sortir l’essentiel. </p>\n\n\n\n<p>Je lui ai demandé de me faire un résumé de la théorie des cordes et voici ce qu’il m’a répondu : </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"692\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221202-chq.webp\" alt=\"\" class=\"wp-image-131727\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221202-chq.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221202-chq-300x208.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221202-chq-768x531.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Plutôt pas mal non ? Évidemment dans les paramètres, vous pouvez choisir si vous voulez des réponses plus travaillées qui demanderont un peu plus de temps d’analyse ou des réponses plus rapides et donc peut-être d’une qualité moindre.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221202-cgh.webp\" alt=\"\" class=\"wp-image-131729\" width=\"390\" height=\"358\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221202-cgh.webp 818w, https://korben.info/app/uploads/2022/12/SCR-20221202-cgh-300x275.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221202-cgh-768x704.webp 768w\" sizes=\"(max-width: 390px) 100vw, 390px\" /></figure></div>\n\n\n<p>Contrairement à beaucoup de gens, Andi est très au fait des dernières découvertes scientifiques comme vous pouvez le voir…</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221201-tpy.webp\" alt=\"\" class=\"wp-image-131724\" width=\"689\" height=\"499\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221201-tpy.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221201-tpy-300x217.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221201-tpy-768x556.webp 768w\" sizes=\"(max-width: 689px) 100vw, 689px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-607714234\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Et il peut même vous aider à y voir plus clair dans le jeu de votre chef au bureau ou de votre animateur TV préféré.

Ça me parait impossible et je suis de ceux qui pensent que Twitter a encore une belle et longue vie devant lui.</p>\n\n\n\n<p>Si vous avez exporté vos données Twitter, vous avez dû remarquer que vous pouvez consulter tout ça au travers d’une page HTML fournie dans l’archive. Mais celle-ci présente plusieurs problèmes. Par exemple, si vous cliquez sur l’une des images contenues dans un tweet, vous êtes renvoyé vers le site de Twitter. Ce qui est complètement con si demain votre compte est supprimé ou que Twitter disparait.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"487\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221201-nmq.webp\" alt=\"\" class=\"wp-image-131709\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221201-nmq.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221201-nmq-300x146.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221201-nmq-768x374.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /><figcaption class=\"wp-element-caption\"><em>Comment télécharger une archive de vos données Twitter ?</em></figcaption></figure></div>\n\n\n<p>Comme les tweets sont archivés en JSON, il est compliqué de simplement les copier-coller pour les mettre ailleurs. Même les images fournies ne sont pas exactement identiques à celles que vous avez envoyées. Elles sont étrangement plus petites. C’est dommage.</p>\n\n\n\n<p>Concernant les DM, même s’ils sont présents dans l’archive, on ne peut pas savoir qui les a envoyés puisque les noms des émetteurs ont été retirés de l’archive. Enfin, les liens inclus dans les messages ne sont pas en clair, mais sont raccourcis. Donc impossible de savoir de quoi ça cause sans cliquer dessus. Et surtout, si un jour Twitter retire son domaine lié aux URLs raccourcies, et bien plus aucun de ces liens ne fonctionnera.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1495201034\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Tous ces petits détails ont incité Tim Hutton et ses amis à agir en proposant un script baptisé Twitter Archive Parser qui « répare » tous ces défauts. En effet, une fois lancé comme ceci sur votre archive…</p>\n\n\n\n<pre class=\"wp-block-code\"><code>python parser.py</code></pre>\n\n\n\n<p>Le script se charge alors de convertir tous vos tweets en markdown et HTML en y intégrant les bonnes images (dans leur taille d’origine), les vidéos et les liens intégrés. Toutes les URLs raccourcies t.co sont ainsi remplacées par les vrais liens et les images récupérées sont stockées dans un dossier spécifique pour que vous puissiez ensuite les utiliser ou les stocker ailleurs.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/supermeme_17h7_54.webp\" alt=\"\" class=\"wp-image-131713\" width=\"351\" height=\"415\" srcset=\"https://korben.info/app/uploads/2022/12/supermeme_17h7_54.webp 635w, https://korben.info/app/uploads/2022/12/supermeme_17h7_54-254x300.webp 254w\" sizes=\"(max-width: 351px) 100vw, 351px\" /></figure></div>\n\n\n<p>Si des pseudos sont absents de l’archive, ce parser est également capable de retrouver tous ces identifiants manquants directement depuis Twitter.com pour les réintégrer dans l’archive. Les DMs sont également convertis en markdown avec leurs médias, leurs liens en clair et bien sûr le pseudo des gens qui vous les ont envoyés.</p>\n\n\n\n<p>Enfin, l’outil récupère également une liste de vos followers et de vos followings ce qui peut également servir pour d’autres choses.</p>\n\n\n\n<p>Si le script pour intéresse, <a rel=\"noopener\" href=\"https://github.com/timhutton/twitter-archive-parser\" target=\"_blank\">son code est sur Github ainsi que les explications techniques pour le lancer</a>.</p>\n",

Cette clé est publique donc créez quelque chose de random et assez long pour que personne ne puisse la deviner. Autrement, quelqu’un pourra s’amuser à vous envoyer des notifications.

La première, c’est un clone de Daisy Disk (logiciel payant) qui vous permet de débusquer les fichiers les plus gros qui trainent sur votre ordinateur. Si vous avez de vieux films, de gros zip ou des programmes d’install volumineux, celui-ci saura les retrouver et vous pourrez les dégager d’un simple clic.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"625\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221201-c2i-2.webp\" alt=\"\" class=\"wp-image-131682\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221201-c2i-2.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221201-c2i-2-300x188.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221201-c2i-2-768x480.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>La seconde fonctionnalité vous permettra de partir à la chasse de tous les fichiers que vous avez en double. De quoi dégraisser le Willy sans douleur.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"625\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221201-cln-2.webp\" alt=\"\" class=\"wp-image-131685\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221201-cln-2.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221201-cln-2-300x188.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221201-cln-2-768x480.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Enfin, la dernière fonctionnalité nommée « Organizer » va vous permettre de faire le tri dans un répertoire en passant très rapidement en revue tout ce qui s’y trouve pour le supprimer ou le classer dans des répertoires. Cette fonctionnalité est très utile si vous êtes comme moi et que vous stockez des centaines de fichiers dans des dossiers sans vraiment savoir ce qu’il y a dedans. Vous pourrez facilement identifier les fichiers que vous n’avez pas utilisés depuis longtemps et les supprimer pour gagner de l’espace sur votre disque dur.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"625\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221201-cb0.webp\" alt=\"\" class=\"wp-image-131686\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221201-cb0.webp 1000w, https://korben.info/app/uploads/2022/12/SCR-20221201-cb0-300x188.webp 300w, https://korben.info/app/uploads/2022/12/SCR-20221201-cb0-768x480.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Comme je le disais, Shorui est gratuit et c’est vraiment pratique !

On crie parfois au génie pour des trucs qu’on a déjà vu (en mieux) ailleurs. Mais je me suis laissé tenté par le côté jeu de cartes / <em>roguelite</em>, devenu nomade grâce à la console de Nintendo, ainsi que de l’ambiance horreur… C’était parfait pour accompagner mes fêtes de fin d’année. 😀</p>\n\n\n\n<p>Et si je vous en parle aujourd’hui, c’est évidemment parce qu’il a réussi à me convaincre. Et je ne peux pas VRAIMENT vous dire pourquoi.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/Inscryption-Switch-6-1024x576.webp\" alt=\"\" class=\"wp-image-132088\" srcset=\"https://korben.info/app/uploads/2023/01/Inscryption-Switch-6-1024x576.webp 1024w, https://korben.info/app/uploads/2023/01/Inscryption-Switch-6-300x169.webp 300w, https://korben.info/app/uploads/2023/01/Inscryption-Switch-6-768x432.webp 768w, https://korben.info/app/uploads/2023/01/Inscryption-Switch-6.webp 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>On débute le jeu face à un mystérieux adversaire, un conteur, qui va nous narrer en direct notre propre histoire, en portant des masques pour jouer les différents personnages. Il nous explique les règles, le déroulement, on se déplace sur une carte et à chaque arrêt, on va pouvoir modifier son deck (ajouts, modifications de cartes, etc.) ou combattre avec. Si l’on perd, on recommence à zéro. Enfin pas totalement, car on débloque quand même des éléments qui vont rester d’une partie à l’autre. 🤓</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-90183500\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Au niveau du jeu en lui-même, le système ressemble à ce qu’on peut connaître chez <a rel=\"noopener\" href=\"https://hearthstone.blizzard.com/fr-fr\" target=\"_blank\">Hearthstone</a>, <a rel=\"noopener\" href=\"https://magic.wizards.com/fr\" target=\"_blank\">Magic the Gathering</a>, etc. mais bien sûr avec des subtilités qui lui sont propres (par exemple, il faut sacrifier une carte pour pouvoir en jouer une autre ! Ou alors le décompte des points qui est fait à l’aide d’une balance). Et puis au détour d’une partie, on va remarquer des choses… Bizarres…</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/Inscryption-Switch-3-1024x576.webp\" alt=\"\" class=\"wp-image-132089\" srcset=\"https://korben.info/app/uploads/2023/01/Inscryption-Switch-3-1024x576.webp 1024w, https://korben.info/app/uploads/2023/01/Inscryption-Switch-3-300x169.webp 300w, https://korben.info/app/uploads/2023/01/Inscryption-Switch-3-768x432.webp 768w, https://korben.info/app/uploads/2023/01/Inscryption-Switch-3.webp 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>À partir de là, difficile de vous expliquer sans spoiler, alors je vais rester vague. Disons que vos compétences en terme d’<a href=\"https://fr.wikipedia.org/wiki/Escape_the_room\" target=\"_blank\" rel=\"noopener\">escape room</a> pourraient être mises à l’épreuve. Un jeu dans le jeu ? Qui lui-même est dans un jeu ? On perd pied, le cerveau explose en quatre dimensions, et on comprend le génie d’<a href=\"https://www.inscryption.com/\" target=\"_blank\" rel=\"noopener\">Inscryption</a>.</p>\n\n\n\n<p>Je ne vais pas vous dire que c’est un titre absolument incroyable ou parfait, car clairement, il ne sera pas au goût de tout le monde. Il a des petits défauts. L’ambiance un peu glauque peut rebuter. Il faut être adepte de <em>deck building</em>, aimer résoudre des énigmes, ne pas avoir peur de (tout ?) perdre.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"577\" src=\"https://korben.info/app/uploads/2023/01/Screenshot-98.webp\" alt=\"\" class=\"wp-image-132101\" srcset=\"https://korben.info/app/uploads/2023/01/Screenshot-98.webp 1000w, https://korben.info/app/uploads/2023/01/Screenshot-98-300x173.webp 300w, https://korben.info/app/uploads/2023/01/Screenshot-98-768x443.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure>\n\n\n\n<p>Malgré cela, et même s’il ne révolutionne aucunement le genre, <a href=\"https://www.inscryption.com/\" target=\"_blank\" rel=\"noopener\">Inscryption</a> propose un <em>gameplay</em> très solide ainsi qu’une histoire qui tirent pleinement partie du média : le jeu vidéo.</p>\n\n\n\n<p>Il coûte moins de 20€ et propose une expérience absolument unique, tellement originale, tellement prenante, que j’aurais été triste de passer à côté. Alors je vous le conseille : jetez-y un œil ! Et essayez de ne pas le perdre. 😉</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://www.inscryption.com/\" target=\"_blank\" rel=\"noopener\">Inscryption</a> est disponible sur <a href=\"https://store.steampowered.com/app/1092790/Inscryption/\" target=\"_blank\" rel=\"noopener\">Steam</a>, <a href=\"https://store.playstation.com/fr-fr/concept/10004707/\" target=\"_blank\" rel=\"noopener\">Playstation 4 & 5</a>, et <a href=\"https://www.nintendo.fr/Jeux/Jeux-a-telecharger-sur-Nintendo-Switch/Inscryption-2297457.html\" target=\"_blank\" rel=\"noopener\">Nintendo Switch</a></h2>\n",

Pourtant il n’est pas exempt de défauts, on va en parler, mais disons que le hérisson bleu n’avait jamais réussi à me convaincre totalement depuis son passage à la troisième dimension. Certains titres étaient plutôt réussis (les Sonic Adventure, Generations, Colours, ou même Secrets Rings si si) mais j’étais loin d’y prendre autant de plaisir que sur Megadrive, ou plus récemment sur <a href=\"https://amzn.to/3QcnqB1\" target=\"_blank\" rel=\"noopener\">Sonic Mania</a>.</p>\n\n\n\n<p>Ça démarrait plutôt mal : des environnements « réalistes » un peu ternes et vides, des ennemis au design triste et grisâtre, un aspect sonore très épuré avec de faux airs de <a href=\"https://amzn.to/3icYk8E\" target=\"_blank\" rel=\"noopener\">Breath of the Wild</a>, des structures (rampes, loopings, ressorts…) qui semblent flotter dans le ciel… Bref, pas très envie d’y jouer…</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/Sonic-Frontiers-1-1024x576.jpg\" alt=\"\" class=\"wp-image-132059\" srcset=\"https://korben.info/app/uploads/2023/01/Sonic-Frontiers-1-1024x576.jpg 1024w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-1-300x169.jpg 300w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-1-768x432.jpg 768w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-1.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /><figcaption class=\"wp-element-caption\">La magie opère !</figcaption></figure>\n\n\n\n<p>Et pourtant, manette en main, ça fonctionne ! On fonce, on prend des tremplins, on <em>grind</em>, on éclate des ennemis en passant, on se surprend à chercher comment atteindre les objets les plus inaccessibles et à remplir toute la carte en fonçant partout, un peu à la Tony Hawk (étrangement !).</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-747232030\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>La formule est la suivante : on commence sur une île assez grande, et on remplit les objectifs que l’on souhaite dans l’ordre qu’on veut. Par exemple, résoudre une énigme, réaliser un défi trouvé en chemin, entrer dans le cyberespace et faire la course dans un niveau « classique », se caler une <a href=\"https://www.youtube.com/watch?v=7NZMTMPZULU\" target=\"_blank\" rel=\"noopener\">session de pêche avec Big The Cat</a>, dégommer un mini-boss… En faisant tout ça, on va obtenir des clefs, qui nous permettent de débloquer les <em>Chaos Emeralds</em>, qui nous permettent ensuite d’affronter le boss de l’île en mode Super Sonic ! 🔥</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/Sonic-Frontiers-2-1024x576.jpg\" alt=\"\" class=\"wp-image-132060\" srcset=\"https://korben.info/app/uploads/2023/01/Sonic-Frontiers-2-1024x576.jpg 1024w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-2-300x169.jpg 300w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-2-768x432.jpg 768w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-2.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /><figcaption class=\"wp-element-caption\">Chaque combat demande une approche différente</figcaption></figure>\n\n\n\n<p>L’histoire est simple mais sympa à suivre, les répliques sont bien écrites, on retrouve bien la personnalité de nos héros favoris, d’ailleurs, bravo à l’équipe de doublage car la version française est chouette ! Aussi, les musiques sont super variées, y a quelques titres vraiment entrainants. 🙂</p>\n\n\n\n<p>On déplore de rares soucis de maniabilité, et certaines phases de jeu frustrantes (le flipper par exemple…) qui entachent un peu l’expérience. Aussi, les graphismes sur la version Switch sont un peu à la ramasse, c’est parfois moche. Sur PC et consoles <em>nextgen</em>, le résultat est beaucoup plus agréable voire franchement joli, même si les îles restent trop vides et ternes à mon goût. J’espère que dans une future suite, ils sauront nous proposer des mondes plus colorés et plus vivants !</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/Sonic-Frontiers-3-1024x576.jpg\" alt=\"\" class=\"wp-image-132061\" srcset=\"https://korben.info/app/uploads/2023/01/Sonic-Frontiers-3-1024x576.jpg 1024w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-3-300x169.jpg 300w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-3-768x432.jpg 768w, https://korben.info/app/uploads/2023/01/Sonic-Frontiers-3.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /><figcaption class=\"wp-element-caption\">Les niveaux du cyberespace sont chatoyants, eux !</figcaption></figure>\n\n\n\n<p>Il n’empêche que c’est un jeu vraiment agréable, pas prise de tête, qui nous propose du fun immédiat, une très bonne durée de vie… Et d’ailleurs, des DLCs gratuits vont sortir tout au long de l’année avec notamment de nouveaux personnages jouables (Tails, Amy Rose… & Knuckles). 😉 Alors malgré ses défauts je ne peux que vous conseiller la dernière aventure de mon hérisson favori !</p>\n\n\n\n<h2 class=\"has-text-align-center\">Acheter Sonic Frontiers sur <a href=\"https://amzn.to/3jLRYgR\" target=\"_blank\" rel=\"noopener\">Nintendo Switch</a> – <a href=\"https://amzn.to/3GeFGoz\" target=\"_blank\" rel=\"noopener\">Playstation 4</a> – <a href=\"https://amzn.to/3ieloUf\" target=\"_blank\" rel=\"noopener\">Playstation 5</a> – <a href=\"https://amzn.to/3GdOvPw\" target=\"_blank\" rel=\"noopener\">Xbox Series S</a></h2>\n",

Apparue en 2009 sur les consoles <em>nextgen</em> de l’époque, la licence est devenue une exclusivité Nintendo en 2014 avec la sortie de la première suite sur WiiU.</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Bayonetta 3 – La sorcière en action (Nintendo Switch)\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/DHt6drrs-Ww?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<p>Il aura fallu attendre 8 ans, rien que ça, pour <a href=\"https://amzn.to/3Q7vYJr\" target=\"_blank\" rel=\"noopener\">la retrouver sur Switch</a> afin de dégommer les anges avec style et cheveux. Parce que voilà, si vous ne le saviez pas, <a href=\"https://amzn.to/3Q7vYJr\" target=\"_blank\" rel=\"noopener\">Bayonetta</a> est une sorcière qui utilise ses cheveux pour invoquer toutes sortes de choses, principalement des démons, mais aussi ses vêtements… C’est pour ça que parfois elle est à moitié à poil. 😅 Rien de choquant je vous rassure, mais ça peut être un peu gênant si quelqu’un vous regarde jouer par-dessus l’épaule.</p>\n\n\n\n<p>Ce n’est qu’un élément parmi d’autres qui caractérisent cette ambiance complètement barrée, baroque, <em>over the top</em> : le scénario, lui aussi, part dans toutes les directions. C’est vraiment fun, inattendu, appuyé par une mise en scène extrêmement généreuse. Des villes entières sont détruites, on se balade dans le multivers, on rencontre de nouveaux personnages, et aussi de nouveaux <em>gameplays</em> : l’expérience est extrêmement variée !</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/Bayonetta-3-2-1024x576.jpg\" alt=\"\" class=\"wp-image-132038\" srcset=\"https://korben.info/app/uploads/2023/01/Bayonetta-3-2-1024x576.jpg 1024w, https://korben.info/app/uploads/2023/01/Bayonetta-3-2-300x169.jpg 300w, https://korben.info/app/uploads/2023/01/Bayonetta-3-2-768x432.jpg 768w, https://korben.info/app/uploads/2023/01/Bayonetta-3-2-1536x864.jpg 1536w, https://korben.info/app/uploads/2023/01/Bayonetta-3-2.jpg 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /><figcaption class=\"wp-element-caption\">Contrairement aux apparences, l’action reste super lisible</figcaption></figure>\n\n\n\n<p>On reste sur une base de <em>beat’em all</em> / <em>hack’n’slash</em>, avec des combos et un système de <em>scoring</em> poussé. Si le jeu est facile à prendre en main, maîtriser les subtilités et enchaîner les platines ne sera pas une mince affaire ! Il y a pas mal de coups, d’armes, de démons à débloquer, ce qui fait qu’on découvre toujours de nouvelles choses, on enchaîne les combats sans se lasser. Les phases d’explorations donnent envie de tout découvrir, y a plein de choses à trouver, bref, sur le contenu là aussi c’est très généreux.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1243728482\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Mon niveau préféré se déroule en plein Paris, ambiance post-apo : sous une lune rouge on tabasse un gros monstre sur le toit de l’arc de triomphe, puis on est poursuivi par une horde de flics zombifiés qui se mettent à danser façon <a href=\"https://www.youtube.com/watch?v=sOnqjkJTMaA\" target=\"_blank\" rel=\"noopener\">Thriller</a>, pour finir avec un hommage au <a href=\"https://fr.wikipedia.org/wiki/Le_Cinqui%C3%A8me_%C3%89l%C3%A9ment\" target=\"_blank\" rel=\"noopener\">Cinquième Élément</a> (preuve de bon goût car il s’agit du meilleur film du monde, non ?)… Ce n’est qu’un petit aperçu de ce qui vous attend !</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2023/01/Bayonetta-3-3-1024x576.jpg\" alt=\"\" class=\"wp-image-132039\" srcset=\"https://korben.info/app/uploads/2023/01/Bayonetta-3-3-1024x576.jpg 1024w, https://korben.info/app/uploads/2023/01/Bayonetta-3-3-300x169.jpg 300w, https://korben.info/app/uploads/2023/01/Bayonetta-3-3-768x432.jpg 768w, https://korben.info/app/uploads/2023/01/Bayonetta-3-3-1536x864.jpg 1536w, https://korben.info/app/uploads/2023/01/Bayonetta-3-3.jpg 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /><figcaption class=\"wp-element-caption\">Viola, nouveau personnage jouable, propose un gameplay plus agressif</figcaption></figure>\n\n\n\n<p>Encore une fois (et c’est pour ça que je vous en parle), il s’agit d’un titre que j’ai beaucoup apprécié. Tout est fun et débile, le contenu est gargantuesque, la durée de vie est conséquente, le <em>gameplay</em> est doté d’une profondeur saisissante. Si vous aimez les jeux d’action intenses et complets, je vous invite à y jeter un œil. Mais alors si vous aimez la baston, impossible de passer à côté !</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://amzn.to/3Q7vYJr\" target=\"_blank\" rel=\"noopener\">Acheter Bayonetta 3 sur Nintendo Switch</a></h2>\n",

Probablement Google Maps ? Si vous êtes libristes, plutôt OpenStreetMap.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1798214772\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Et si vous êtes en Chine, il y a des chances pour que ce soit Baidu Maps.</p>\n\n\n\n<p>Bref, chacun a son service de cartographie préférée. Mais si je vous disais que maintenant vous n’avez plus besoin de choisir grâce à ce bookmarklet ?</p>\n\n\n\n<p>Alors petit rappel pour les plus jeunes, un bookmarklet est un petit bout de JavaScript qui se place dans les favoris de votre navigateur et vous permet d’activer une fonctionnalité sur un site en cours.</p>\n\n\n\n<p>Ainsi, vous pouvez aller sur Google Maps, OpenStreetMaps…etc, vous positionner sur l’endroit de votre choix, puis cliquer sur le bookmarklet pour avoir un accès rapide à des tas de services de cartographie qui vous renverront vers l’endroit que vous avez ciblé.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"720\" height=\"750\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221130-f8l.webp\" alt=\"\" class=\"wp-image-131639\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221130-f8l.webp 720w, https://korben.info/app/uploads/2022/11/SCR-20221130-f8l-288x300.webp 288w\" sizes=\"(max-width: 720px) 100vw, 720px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-982268020\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Mais ce n’est pas tout, puisque OpenSwitchMaps vous propose également d’activer différents outils sur votre carte. Ainsi, vous pourrez récupérer une image PNG de la zone, convertir des coordonnées GPS, lancer une recherche Flickr ou Twitter sur la zone ciblée, ouvrir un éditeur GPX, calculer des distances entre deux points…et ainsi de suite.</p>\n\n\n\n<p>Alors comment ça s’utilise ? Et bien tout d’abord, ajoutez un signet (bookmarklet) à votre navigateur en faisant glisser le lien suivant vers votre barre de signets : <a href=\"//tankaru.github.io/OpenSwitchMapsWeb/index.html#'+location.href;})();\" target=\"_blank\" rel=\"noopener\">OpenSwitchMaps Web</a>.</p>\n\n\n\n<p>Ou en ajoutant la fonction suivant dans un bookmark :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>JavaScript:(function(){ window.location.href='https://tankaru.github.io/OpenSwitchMapsWeb/index.html#'+location.href;})();</code></pre>\n\n\n\n<p>Ensuite, ouvrez Google Maps ou un équivalent puis cliquez sur le bookmark. Et voilà, vous n’avez plus qu’à choisir le service qui vous intéresse.</p>\n\n\n\n<p>C’est super intéressant et pratique si vous interagissez souvent avec des services de cartographie et je suis certain que vous allez découvrir plein de services cools.</p>\n",

En effet, <a href=\"https://en.wikipedia.org/wiki/Yarovaya_law#:~:text=The%20Yarovaya%20law%20(in%20Russian,terror%20and%20public%20safety%20measures.\" target=\"_blank\" rel=\"noopener\">depuis 2016, la Russie oblige les prestataires Telecom</a> à conserver tous le contenu des appels audio, les données, les images et les messages textes qui seraient présents sur des serveurs localisés en Russie, ainsi que les métadonnées et cela pour 6 mois. Toujours d’après cette loi, les réseaux sociaux ou logiciels de messagerie qui utilisent du chiffrement sont également forcés de conserver un accès aux communications chiffrées pour le FSB.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" src=\"https://korben.info/app/uploads/2022/11/Manu23_Vladimir_Putin_spying_with_binoculars_dda95857-9532-4d2d-926b-0559718d64ea.webp\" alt=\"\" class=\"wp-image-131601\" width=\"602\" height=\"402\" srcset=\"https://korben.info/app/uploads/2022/11/Manu23_Vladimir_Putin_spying_with_binoculars_dda95857-9532-4d2d-926b-0559718d64ea.webp 1024w, https://korben.info/app/uploads/2022/11/Manu23_Vladimir_Putin_spying_with_binoculars_dda95857-9532-4d2d-926b-0559718d64ea-300x200.webp 300w, https://korben.info/app/uploads/2022/11/Manu23_Vladimir_Putin_spying_with_binoculars_dda95857-9532-4d2d-926b-0559718d64ea-768x512.webp 768w\" sizes=\"(max-width: 602px) 100vw, 602px\" /></figure></div>\n\n\n<p>L’objectif avec <a href=\"https://spybuster.app/\" target=\"_blank\" rel=\"noopener\"><strong>SpyBuster</strong></a> est donc de détecter les logiciels qui auraient des connexions avec des serveurs russes. En passant un Scan sur ma machine, il détecte évidemment que Telegram est un outil problématique de leur point de vue.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221128-kaq.webp\" alt=\"\" class=\"wp-image-131594\" width=\"710\" height=\"582\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221128-kaq.webp 935w, https://korben.info/app/uploads/2022/11/SCR-20221128-kaq-300x246.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221128-kaq-768x631.webp 768w\" sizes=\"(max-width: 710px) 100vw, 710px\" /></figure></div>\n\n\n<p>Mais SpyBuster ce n’est pas que ça.

D’ailleurs, ce qui serait cool, c’est que MacPaw étende ce logiciel à d’autres pays sympathiques comme la Chine ou les États-Unis qui eux aussi ne se privent pas de piller les données personnelles des internautes. Une version Android et Windows serait également la bienvenue.</p>\n\n\n\n<p><a href=\"https://spybuster.app/\" target=\"_blank\" rel=\"noopener\">À suivre…</a></p>\n",

J’en ai déjà parlé plusieurs fois sur le site et selon différents angles : <a href=\"https://korben.info/incogni-rgpd.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-rgpd.html\">faire respecter vos droits RGPD</a>, <a href=\"https://korben.info/data-brokers-incogni.html\" data-type=\"URL\" data-id=\"https://korben.info/data-brokers-incogni.html\">lutter contre les data brokers</a>, faire effacer ses données personnelles, etc.</p>\n\n\n\n<p>Mais l’outil a aussi une bonne raison d’exister pour d’autres problèmes annexes que l’on peut rencontrer au cas par cas. Moins fréquents que ceux déjà cités, mais qui existe malgré tout. C’est le cas par exemple des arnaques au CPF, ou Compte Professionnel de Formation. Arnaques qui sont en constante augmentation depuis plusieurs années, jusqu’à représenter presque 45 millions d’euros en 2021.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img width=\"800\" height=\"267\" decoding=\"async\" src=\"https://me.korben.info/14i-incognicpf\" alt=\"\"/></figure>\n\n\n\n<p>Comme vous le savez, en France et depuis 2015, chaque personne active professionnellement recevait chaque année un crédit d’heures donnant droit à suivre des formations. Sauf que depuis 2019 ce crédit d’heures a été remplacé par de la moula, chaque travailleur reçoit sur un compte une certaine somme à dépenser « comme il veut ». Pas en frais de restaurant ou en vacances au soleil, calmez-vous hein, mais disons que chacun peut maintenant choisir le type de service qu’il veut utiliser avec plus de latitude (formation en ligne, etc.). Plus de 38 millions de français reçoivent ainsi plusieurs centaines d’euros chaque année, ça fait de belles sommes. Et qui dit pognon à se faire, dit vautours.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"488\" height=\"275\" decoding=\"async\" src=\"https://media.giphy.com/media/12huzxtUKCLVTy/giphy.gif\" alt=\"\"/><figcaption class=\"wp-element-caption\"><em>Des gens à plumer ? I’m in.</em></figcaption></figure></div>\n\n\n<p>Sont donc apparus des escrocs qui ont commencé à se faire passer pour des organismes ou centres de formation officiels et qui cherchent à récupérer les fonds disponibles. Vous commencez donc à recevoir des mails/SMS/appels dans lesquels on va soit vous proposer une fausse formation (souvent assez cher), soit vous demander de vous connecter à votre compte formation via un lien qu’ils vous fournissent (et à travers lequel ils vont être capable de voler vos identifiants). Certains allant même jusqu’à vous suivre sur les réseaux sociaux pour vous démarcher. Et une fois que vous leur avez envoyé votre crédit, ils vont disparaitre dans la nature. En récupérant au passage vos informations personnelles qui pourront éventuellement leur servir également (revente à des data brokers, usurpation d’identité, vol de mot de passe, etc.). Pas de gaspillage ma bonne dame.</p>\n\n\n\n<p>D’ailleurs un petit rappel : vos droits à la formation n’ont pas de limite maximale d’utilisation, vous pouvez les utiliser quand vous voulez (dans 6 mois ou dans 10 ans). Avant de payer une formation quelconque, prenez le temps de vérifier qu’elle est dans les clous, reconnue et validée. Ne vous contentez pas d’une mention sur leur site web éventuel. Cela arrive plus souvent que vous ne le pensez, plusieurs milliers de travailleurs se font avoir chaque année. Si cela a été votre cas, vous pouvez le <a rel=\"noreferrer noopener\" href=\"https://www.moncompteformation.gouv.fr/espace-public/comment-signaler-une-escroquerie-sur-mon-compte-formation\" data-type=\"URL\" data-id=\"https://www.moncompteformation.gouv.fr/espace-public/comment-signaler-une-escroquerie-sur-mon-compte-formation\" target=\"_blank\">signaler ici</a>. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"750\" height=\"184\" src=\"https://korben.info/app/uploads/2022/12/mon-compte-formation.jpg\" alt=\"Mon compte formation\" class=\"wp-image-131930\" srcset=\"https://korben.info/app/uploads/2022/12/mon-compte-formation.jpg 750w, https://korben.info/app/uploads/2022/12/mon-compte-formation-300x74.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></figure></div>\n\n\n<p>Même si une loi devrait être mise en place bientôt pour réguler un peu tout ça (interdiction de démarchage abusif, référencement des organismes, etc.), il n’en reste pas moins que vous avez des armes à votre disposition dès aujourd’hui, <strong><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">dont Incogni</a></strong>.</p>\n\n\n\n<p>Avec Incogni, vous avez la possibilité de contrôler les informations personnelles qui sont accessibles sur le web. Vous pouvez ainsi demander aux services qui ont stocké des informations sur vous de les supprimer. Cependant, il est important de noter que ces services peuvent choisir de ne pas répondre à cette demande, en fonction de leurs propres politiques et de la loi en vigueur. Si cela se produit, le service Incogni peut intervenir pour s’assurer que la demande est traitée de manière appropriée, mais il ne peut pas garantir que toutes les informations seront effectivement supprimées.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"800\" height=\"414\" src=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg\" alt=\"\" class=\"wp-image-130591\" srcset=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg 800w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-300x155.jpg 300w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-768x397.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" /></figure></div>\n\n\n<p>Pour avoir utilisé Incogni personnellement, je peux vous dire que l’on ne se rend pas bien compte de qui a quoi comme donnée nous concernant. Des sociétés dont vous n’avez jamais entendu parler se retrouvent avec vos noms, adresse, numéro de téléphone, parfois numéro de sécurité sociale … alors que vous n’avez jamais donné toutes ces infos à un même site. La magie des données croisées. Il suffit d’obtenir une base de données du service X, d’acheter une autre d’Y, de profiter d’un hack de la messagerie du réseau social Z, combiner les 3 et pouf on un profil ultra complet. Facile ensuite de vous contacter en vous donnant une certaine impression d’être officiel puisqu’ils ont des infos qui sont censées être réservées à des services officiels.</p>\n\n\n\n<p>Bref si vous êtes sensible au respect de votre vie privée et/ou si vous voulez vous protéger à l’avenir, n’hésitez pas à jeter un oeil sur le service. Pour moins de 6€/mois, ils vont gérer tout à votre place.</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Découvrir Incogni !</a></h2>\n",

Son nom : <a href=\"https://github.com/chaiNNer-org/chaiNNer\" target=\"_blank\" rel=\"noopener\"><strong>ChaiNNer</strong></a>.</p>\n\n\n\n<p>ChaiNNer est un outil de traitement d’images qui utilise un fonctionnement à case de graphiques avec des noeuds et des liens entre ces noeuds, ce qui permet d’enchainer des tâches relatives aux images. On y retrouve des fonctionnalités assez classiques de recadrage, de redimensionnement…etc., mais également des tâches infiniment plus complexes puisqu’utilisant des réseaux neuronaux.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/simple_screenshot.webp\" alt=\"\" class=\"wp-image-131556\" width=\"665\" height=\"576\" srcset=\"https://korben.info/app/uploads/2022/11/simple_screenshot.webp 866w, https://korben.info/app/uploads/2022/11/simple_screenshot-300x260.webp 300w, https://korben.info/app/uploads/2022/11/simple_screenshot-768x665.webp 768w\" sizes=\"(max-width: 665px) 100vw, 665px\" /></figure></div>\n\n\n<p>Ainsi, dans vos pipelines, vous pourrez augmenter la taille des images sans perte de qualité avec des algos de type ESRGan, ou rafraichir des photos anciennes avec des modèles de restauration de visage…etc.</p>\n\n\n\n<p>L’outil codé en Python est disponible sur tous les OS (macOS, Windows, Linux) et supporte PyTorch, NCNN et ONNX. Une fois lancé, tout ce que vous avez à faire, c’est de glisser / déposer des noeuds et de les connecter entre eux. Chaque poignée présente sur un noeud dispose de fonctions spécifiques selon sa couleur, ce qui permet de savoir quoi relier avec quoi. Un vrai jeu d’enfant.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1448860395\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Et une fois que vous êtes satisfait de votre « pipe », vous n’avez plus qu’à cliquer sur le bouton vert « Run » pour lancer le process. Vraiment cool et à tester d’urgence !</p>\n\n\n\n<p><a href=\"https://github.com/chaiNNer-org/chaiNNer\" target=\"_blank\" rel=\"noopener\">ChaiNNer est à découvrir ici sur github.</a></p>\n",

Elle est conçue pour être utilisée en intérieur même pour vos grillades les plus extrêmes et est plutôt silencieuse, ce qui est un plus pour moi qui aime bien écouter de la musique quand je cuisine. </p>\n\n\n\n<h2>Simplicité d’utilisation</h2>\n\n\n\n<p>J’ai donc eu l’occasion de tester cet appareil de chez Ultenic depuis quelques semaines, et je dois dire que je suis vraiment content des plats que j’ai cuisinés. Pour vous expliquer un peu mieux le truc, Ultenic est une marque qui possède une sous-marque appelée CHEFREE, spécialisée dans les appareils de cuisine comme ce grill « air fryer » AFG01.</p>\n\n\n\n<p>Si vous connaissez déjà les friteuses à air de la marque, sachez que l’AFG01 de CHEFREE est plus polyvalente que les modèles précédents (K10 et K20). En effet, elle dispose de huit fonctions de cuisson différentes : barbecue, crisper, rôtir, cuire, griller, frire, steak et préchauffage (bon, OK ce n’est pas vraiment un mode de cuisson, mais je le compte quand même). </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"563\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/grill.webp\" alt=\"\" class=\"wp-image-132017\" srcset=\"https://korben.info/app/uploads/2022/12/grill.webp 563w, https://korben.info/app/uploads/2022/12/grill-225x300.webp 225w\" sizes=\"(max-width: 563px) 100vw, 563px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/panneau-controle.webp\" alt=\"\" class=\"wp-image-132016\" width=\"578\" height=\"434\" srcset=\"https://korben.info/app/uploads/2022/12/panneau-controle.webp 1000w, https://korben.info/app/uploads/2022/12/panneau-controle-300x225.webp 300w, https://korben.info/app/uploads/2022/12/panneau-controle-768x576.webp 768w\" sizes=\"(max-width: 578px) 100vw, 578px\" /></figure></div>\n\n\n<p>Autant vous dire que vous pouvez tout faire avec cet appareil, qui se comporte comme un mini four ! À titre perso, au même titre que la K10 et la K20, cet appareil me simplifie vraiment la vie tous les jours. Plus besoin d’allumer mon four ou mes plaques de cuisson pour réchauffer un petit truc ou faire cuire une pognée de nuggets… </p>\n\n\n\n<p>Les accessoires inclus avec l’AFG01 sont d’ailleurs très utiles. Le panier à frites et la plaque de grill sont plutôt cool pour préparer des croquettes de poulet maison ou des steaks. Et j’ai été agréablement surpris par la qualité de la cuisson notamment au niveau de la viande. Si vous dosez bien la température et le temps de cuisson, le résultat sera tendre et juteux à souhait. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"563\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/chefree-burger-frites.webp\" alt=\"\" class=\"wp-image-132014\" srcset=\"https://korben.info/app/uploads/2022/12/chefree-burger-frites.webp 563w, https://korben.info/app/uploads/2022/12/chefree-burger-frites-225x300.webp 225w\" sizes=\"(max-width: 563px) 100vw, 563px\" /></figure></div>\n\n\n<h2>Des résultats de qualité</h2>\n\n\n\n<p>Je peux donc tout faire cuire avec cette friteuse à air qui je le rappelle a une capacité de 6 litres pour le bac, et de 4 litres pour le panier. Donc ça reste quand même un bon volume pour cuisiner pour 4 personnes.</p>\n\n\n\n<p>J’ai par exemple fait des pavés de boeuf et la viande est restée saignante comme je l’aime. Même chose avec les frites qui étaient croustillantes. Bref, on obtient le même résultat qu’avec une friteuse à huile ou un barbecue bien chaud. Manque que l’odeur du feu de bois… par contre, la dégoulinade d’huile de friture ne me manque pas. Et contrairement à ce qu’on pourrait penser, non, la viande ne se dessèche pas.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"563\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/frites2.webp\" alt=\"\" class=\"wp-image-132013\" srcset=\"https://korben.info/app/uploads/2022/12/frites2.webp 563w, https://korben.info/app/uploads/2022/12/frites2-225x300.webp 225w\" sizes=\"(max-width: 563px) 100vw, 563px\" /></figure></div>\n\n\n<h2>Une cuisson rapide et efficace</h2>\n\n\n\n<p>Grâce aux quatre niveaux de chauffage et à sa puissance de 1660 watts, vous pouvez facilement ajuster la chaleur pour cuire la viande à différents stades (saignant, moyen et bien cuit). Elle consomme également 80% d’énergie en moins par rapport aux méthodes de cuisson traditionnelles, ce qui n’est pas négligeable surtout en ce moment.</p>\n\n\n\n<p>L’AFG01 est également dotée d’un système de préchauffage qui permet de régler la température en amont. Cela est très utile pour obtenir une cuisson uniforme et un meilleur « croustillant » de vos aliments. Par contre, il faudra être patient (c’est le concept du préchauffage) et attendre quelques minutes avant de mettre les aliments dedans, mais cela en vaut vraiment la peine. Après vous pourrez retourner bidouiller sur le PC, et attendre que ça sonne.</p>\n\n\n\n<h2>Facile à nettoyer</h2>\n\n\n\n<p>Concernant le nettoyage de la CHEFREE, c’est également très simple. </p>\n\n\n\n<p>Le revêtement anti-adhésif du bac et de la plaque de grill rend le nettoyage rapide et facile. Il suffit de rincer les pièces à l’eau chaude et de les essuyer avec un chiffon doux.</p>\n\n\n\n<p>Même si je ne fais pas de « conseil en investissement » (lol), je vous la recommande fortement, car pour un peu plus de 200 €, c’est loin d’être un gadget. Je l’utilise tous les jours avec sa petite soeur la K20 et je ne pourrais plus m’en passer. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/K20.webp\" alt=\"\" class=\"wp-image-132015\" srcset=\"https://korben.info/app/uploads/2022/12/K20.webp 1000w, https://korben.info/app/uploads/2022/12/K20-300x225.webp 300w, https://korben.info/app/uploads/2022/12/K20-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Je ne fais plus rien bruler, on mange beaucoup moins gras, je crame moins de gaz et d’électricité, et les frites sont au top, y compris quand je les fais avec de vraies patates coupées en morceaux.</p>\n\n\n\n<p>Si j’avais un petit bémol à apporter quand même, c’est qu’elle prend un peu de place et qu’elle peut ne pas être adaptée à tous les espaces de rangement en raison de son couvercle qui s’ouvre par le haut. C’est à prendre en compte si vous avez une petite cuisine. Mais bon, à part ça c’est vraiment top et une fois encore c’est un appareil qui s’appelle « friteuse à air » mais que je considère plutôt comme un mini four super efficace, paramétrable à souhait et polyvalent. Mon prochain projet avec, c’est d’y faire cuire mon propre pain.</p>\n\n\n\n<h2>60 euros de réduction sur l’AFG01</h2>\n\n\n\n<p>Et pour encore plus d’économies, profitez du code promo exclusif de 30 euros, valable jusqu’au 24 décembre, en utilisant le code <strong>AFG01KORBEN</strong>.

L’année arrive à sa fin et comme vous avez peut-être remarqué si vous me suivez sur <a href=\"http://twitch.tv/korbenfr\" target=\"_blank\" rel=\"noopener\">Twitch</a>, j’ai commencé un petit break qui va durer jusqu’au début janvier. Ne vous inquiétez pas, comme d’habitude, j’ai plein d’articles programmés pour les jours qui viennent, donc ce sera totalement transparent pour vous 🙂</p>\n\n\n\n<p>Alors je ne sais pas comment s’est passé l’année 2022 pour vous, mais pour moi, ça s’est plutôt bien déroulé. Voici d’ailleurs quelques « achievements » dont je suis plutôt fier. Tout d’abord, j’ai réussi à remettre ma coquille de noix (korben.info) sur pied malgré les difficultés économiques de l’année dernière. Le trafic sur mon site a même plutôt augmenté, donc c’est super cool et je retrouve beaucoup de plaisir à écrire, surtout en cette période de fêtes. C’est donc une affaire qui roule 🙂</p>\n\n\n\n<p>Mon compte <a href=\"http://tiktok.com/@korbeninfo?lang=fr\" target=\"_blank\" rel=\"noopener\">TikTok</a> a également explosé, ce qui m’offre également de nouvelles opportunités. J’aime bien tourner ces petites vidéos et les gens ont l’air de les apprécier, donc c’est cool, je vais continuer. Ensuite, sur un plan personnel, j’ai bien avancé dans les travaux à la maison. C’est de plus en plus habitable même s’il fait encore bien froid à l’intérieur… Mais là, à part dépenser une fortune pour une isolation par l’extérieur, je ne vois pas ce qui pourrait me sauver. J’ai également obtenu mon permis tronçonneuse et j’en suis extrêmement fier. Et enfin, je me suis enfin marié après avoir dû décaler la cérémonie de 2 ans à cause du Covid. Woohoo !</p>\n\n\n\n<p>Voilà pour 2022. C’était cool et pour cette année 2023 qui arrive, je n’ai pas spécialement d’ambitions autres que de continuer sur ma lancée, c’est-à-dire de faire plaisir aux <a href=\"https://patreon.com/korben\" target=\"_blank\" rel=\"noopener\">Patreons</a> et de continuer à partager avec vous toutes mes découvertes tech au fil de l’eau. </p>\n\n\n\n<p>Et vous, comment ça s’est passé ?</p>\n\n\n\n<p>A très bientôt ! Et passez de bonnes fêtes de fin d’année 🍾 !</p>\n",

Il y a les développeurs qu’il faut chouchouter évidemment, mais également les designers et les gens du marketing afin que le « produit » qui est porté par votre entreprise rencontre un franc succès. Sacrée mission, et tout ça sans jamais perdre votre sourire ni votre sens de l’humour !</p>\n\n\n\n<p>Pas simple 🙂</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"1024\" height=\"683\" decoding=\"async\" src=\"https://me.korben.info/rr-talent-product-manager-trk\" alt=\"\"/></figure></div>\n\n\n<p>Ce métier de product manager est encore assez récent en France, mais a su se rendre indispensable dans de nombreuses entreprises Tech. Vous l’aurez compris, le rôle d’un product manager est donc de faire correspondre les besoins des utilisateurs avec les attentes de la société qui l’emploie afin de créer un modèle économique pérenne. Le product manager doit donc garder un oeil sur la faisabilité technique du projet, sa facilité d’utilisation et sa valeur en termes de business.</p>\n\n\n\n<p>Cet article a été rédigé en partenariat avec <a href=\"https://me.korben.info/pbh-talentio\" target=\"_blank\" rel=\"noopener\">talent.io</a>. Si ce genre de sujet vous intéresse, vous pouvez rejoindre leur communauté tech, le talent club. En vous inscrivant gratuitement, vous aurez accès à du contenu exclusif, comme des conseils d’experts qui travaillent chez Google, Deezer, Sorare… Vous aurez également accès à leur étude des salaires annuelle, ainsi que la possibilité de poser vos questions carrière à l’ensemble des 40 000 membre de manière anonyme.</p>\n\n\n\n<p class=\"has-text-align-center\"><strong><a href=\"https://me.korben.info/44c-talent-productmanager\" target=\"_blank\" rel=\"noopener\">Rejoignez la communauté talent club en cliquant ici</a></strong></p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><a href=\"https://me.korben.info/44c-talent-productmanager\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/talent-1.webp\" alt=\"\" width=\"541\" height=\"429\"/></a></figure></div>\n\n\n<p>Ainsi, la réussite d’un projet se mesure sur l’impact généré par le produit et non plus bêtement sur « Est-ce que ça a été livré ? ». On s’éloigne donc d’une mesure bête et méchante comme une « quantité de features » sorties pour plutôt mesurer si l’application (ou l’objet) a été un succès en matière d’utilisateurs ou d’acheteurs. C’est beaucoup plus pragmatique comme approche et ça permet par la suite de prendre des décisions beaucoup plus éclairées sur les améliorations à apporter.</p>\n\n\n\n<p>Bref, vous l’aurez compris, un produit réussi c’est un produit qu’on peut faire techniquement (ce n’est pas un scoop), qui sera utilisé régulièrement par les utilisateurs et enfin, c’est un produit qui rapporte de l’argent ou un fort gain de temps ou d’efficacité. Si votre produit ne remplit pas ces objectifs, il vous faut un product manager, alors pourquoi pas vous ?</p>\n\n\n\n<p><strong>Alors en tant que dev, quelles sont les raisons principales de quitter son job de codeur pour devenir product manager ?</strong></p>\n\n\n\n<p>Déjà, ça peut paraitre idiot dit comme ça, mais vous aurez beaucoup plus d’influence sur le projet. Avec votre vue d’ensemble, vous déciderez des priorités et des objectifs à atteindre et c’est vous qui mènerez le projet à son succès (ou à sa perte ^^).</p>\n\n\n\n<p>Le métier de product manager est également beaucoup plus varié. En tant que développeur, vous vous concentrez essentiellement sur des problématiques techniques, allant jusqu’à compter les accolades dans votre code. Le product manager, avec une casquette technique, a l’opportunité de travailler sur des problématiques plus larges qui vont bien au-delà du code. Cela peut être des aspects plus stratégiques comme la commercialisation, la capitalisation des retours utilisateurs, l’amélioration du design…etc. C’est d’un certain point de vue, beaucoup plus enrichissant.</p>\n\n\n\n<p>Enfin, devenir product manager ça veut aussi dire faire le lien entre toutes les équipes. Développeurs, designers, marketeux, data scientist, c’est vous qui donnez le « la » et qui êtes le chef d’orchestre de tout ce petit monde. Donc forcément, dans ce job, vous apprendrez énormément au contact des autres, à la fois techniquement et humainement.</p>\n\n\n\n<p>Alors bien sûr, tout n’est pas tout rose et il y a de nombreux défis à relever quand on passe de dev à product manager. Vous serez responsable des enjeux commerciaux donc ce sera à vous de prendre les bonnes décisions pour que le produit « fonctionne » et rapporte à l’entreprise. Vous devrez également gérer les conflits et les différences de points de vue entre les équipes et les personnes. Et vous devrez sans cesse décider de tout… Faire des choix sur la stratégie, sur la technique, sur les équipes… etc. Ces choix auront des impacts que vous devrez assumer. Bref, Product Manager, c’est aussi savoir prendre des décisions difficiles.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"683\" src=\"https://korben.info/app/uploads/2022/12/62a72d22a867303f3abd5ae4_2.2-Skills-of-a-PM.webp\" alt=\"\" class=\"wp-image-131855\" srcset=\"https://korben.info/app/uploads/2022/12/62a72d22a867303f3abd5ae4_2.2-Skills-of-a-PM.webp 1024w, https://korben.info/app/uploads/2022/12/62a72d22a867303f3abd5ae4_2.2-Skills-of-a-PM-300x200.webp 300w, https://korben.info/app/uploads/2022/12/62a72d22a867303f3abd5ae4_2.2-Skills-of-a-PM-768x512.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Si en sachant tout cela, ça vous botte encore, sachez qu’il n’y a pas spécifiquement de formation pour passer de développeur à product manager. Vous devez être capable de comprendre les responsabilités, les compétences et les enjeux du métier. Vous devez être un excellent communiquant et surtout être très organisé avec une forte résilience / adaptabilité et une grande capacité d’apprentissage, car ça va fuser dans tous les sens, je vous le promets ^^. </p>\n\n\n\n<p>Je vous invite à trouver des mentors dans ce domaine et de bouquiner des livres sur le sujet, mais également de vous intéresser à tous les aspects du produit sur lequel vous travaillez. L’objectif c’est de montrer au sein de votre entreprise que vous êtes capable de travailler sur une mission de product management.</p>\n\n\n\n<p>Vous pouvez également renforcer ou travailler certaines compétences, sur lesquelles vous vous sentez plus fragiles comme la communication, la gestion de projet, la compréhension des enjeux commerciaux, etc. Il existe des formations et des tas de livres sur le leadership, l’empathie au travail et la communication. Vous pourrez ainsi rapidement mettre en oeuvre vos compétences sur des projets concrets.</p>\n\n\n\n<p>Si votre reconversion est dans un cadre de changement d’entreprise, pensez à mettre en avant vos compétences de développeur dans votre candidature, pour montrer que vous avez les bases techniques pour rejoindre l’entreprise comme product manager, tout en soulignant votre expérience de travail en équipe, vos capacités à résoudre des problèmes complexes et votre intérêt pour les enjeux commerciaux. </p>\n\n\n\n<p>N’oubliez pas, l’objectif c’est de convaincre un employeur potentiel que vous saurez lui apporter de la valeur en tant que product manager. Beaucoup plus que si vous étiez resté développeur.</p>\n\n\n\n<p>En conclusion, passer de développeur à product manager c’est comme passer d’un sport individuel à un sport d’équipe : c’est passionnant, stimulant et ça bouge tout le temps ! </p>\n\n\n\n<p>Ainsi, si vous avez envie d’avoir une vue d’ensemble sur un projet, de travailler vraiment en équipe et de prendre des décisions importantes, le job de product manager est probablement un métier qui vous conviendra.</p>\n\n\n\n<p>Prêt à quitter le code pour devenir le prochain Didier Deschamps du numérique ?</p>\n\n\n\n<p>Pour plus de conseils sur votre carrière, vous pouvez rejoindre <a href=\"https://me.korben.info/44c-talent-productmanager\" target=\"_blank\" rel=\"noopener\">le talent club</a>.

Cela vous permettra ainsi de retirer, convertir ou extraire les pistes audio de vos vidéos, ou encore de créer des GIFs animés à partir de celles-ci. Vous pourrez également intégrer en dur les sous-titres sur une vidéo ou réparer / stabiliser une vidéo et j’en passe.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"984\" height=\"750\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221116-e9m.webp\" alt=\"\" class=\"wp-image-131453\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221116-e9m.webp 984w, https://korben.info/app/uploads/2022/11/SCR-20221116-e9m-300x229.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221116-e9m-768x585.webp 768w\" sizes=\"(max-width: 984px) 100vw, 984px\" /></figure></div>\n\n\n<p>Bref, très cool surtout que vous pouvez créer également vos propres presets en utilisant les paramètres de FFMpeg (mais là, faudra bosser un peu plus la documentation).</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-530193462\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Tout ce qui est conversion est également très simple avec Videomass.

Enfin, seulement si vous êtes sous Mac, car <a href=\"http://numi.io/\" target=\"_blank\" rel=\"noopener\"><strong>Numi</strong></a> ne fonctionne que sur cet OS.</p>\n\n\n\n<p>Numi est une calculatrice (en beta) d’un nouveau genre qui permet de faire des calculs normaux, de la conversion d’unités, du calcul de pourcentage, du calcul de fonctions…etc.,etc. au travers d’une interface minimaliste et simple au possible. Elle permet ainsi de décrire des tâches de manière naturelle et d’obtenir instantanément une réponse précise. Par exemple, « 20 $ en euros – remise de 5 % » ou « aujourd’hui + 2 semaines ».</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/SCR-20221215-lgb.webp\" alt=\"\" class=\"wp-image-131895\" width=\"374\" height=\"376\" srcset=\"https://korben.info/app/uploads/2022/12/SCR-20221215-lgb.webp 746w, https://korben.info/app/uploads/2022/12/SCR-20221215-lgb-298x300.webp 298w, https://korben.info/app/uploads/2022/12/SCR-20221215-lgb-150x150.webp 150w\" sizes=\"(max-width: 374px) 100vw, 374px\" /></figure></div>\n\n\n<p>Voici quelques unes de ses possibilités : </p>\n\n\n\n<ul>\n<li><strong>Conversion d’unités</strong> : permet de convertir une unité en une autre en utilisant les mots-clés « in », « into », « as » ou « to ». Numi convertira automatiquement les unités pour effectuer les opérations si cela est nécessaire lors de la conversion.</li>\n\n\n\n<li><strong>Conversion de fuseau horaire</strong> : vous pouvez utiliser la fonction « time » ou « now » pour obtenir l’heure dans votre fuseau horaire. Vous pouvez préfixer ces fonctions avec le nom du fuseau horaire (ou utiliser « in » avec un suffixe de fuseau horaire) pour obtenir l’heure actuelle pour un lieu spécifié. Les résultats sont toujours synchronisés avec l’heure mondiale, donc en tout temps vous obtiendrez l’heure exacte. Il est également possible de convertir une heure ou une date spécifique d’un fuseau horaire à un autre. Ou calculez la différence entre les heures dans différents fuseaux horaires.</li>\n\n\n\n<li><strong>Opérations</strong> : vous pouvez utiliser des opérateurs en signe et en mot. Plusieurs expressions peuvent être empilées ensemble. Notez que les expressions seront multipliées si elles sont utilisées dans des parenthèses les unes après les autres.</li>\n\n\n\n<li><strong>Nombres</strong> : en plus du système numérique décimal, il est possible d’utiliser des nombres en binaire, en octal ou en hexadécimal en utilisant le préfixe approprié : 0b, 0o et 0x. Vous pouvez utiliser les mots-clés « sci » ou « scientific » pour formater les résultats en notation scientifique.</li>\n\n\n\n<li><strong>Devises</strong> : vous pouvez utiliser les codes ISO 4217 pour les devises (comme USD, RUB, CAD, etc.). Vous pouvez également utiliser les noms et les symboles des devises courantes, comme le $ pour les dollars américains, les roubles pour les roubles russes ou € pour l’euro. Numi met à jour les taux de change plusieurs fois par jour en utilisant le service de taux de change ouvert. Numi prend également en charge une grande liste de cryptomonnaies avec des mises à jour horaires des taux.</li>\n\n\n\n<li><strong>Pourcentages</strong> : en plus des opérations de pourcentage générales comme l’ajout ou la soustraction d’un pourcentage d’une valeur ($10 – 40%), vous pouvez également utiliser des opérations supplémentaires : pourcentage d’une valeur, ajout de pourcentage, soustraction de pourcentage, pourcentage d’une valeur par rapport à une autre, ajout de pourcentage d’une valeur par rapport à une autre, soustraction de pourcentage d’une valeur par rapport à une autre.</li>\n\n\n\n<li><strong>Fonctions</strong> : Numi supporte une large gamme de fonctions mathématiques courantes, y compris les fonctions trigonométriques, exponentielles et logarithmiques. Vous pouvez également utiliser des fonctions d’arrondi, de pourboire et de pourcentage de gain/perte.</li>\n</ul>\n\n\n\n<p>En utilisant ces fonctionnalités, Numi vous permet de simplifier vos calculs et de les effectuer rapidement et facilement sur votre Mac. Essayez-la dès maintenant pour voir à quel point elle est rapide, jolie et bien plus agréable que ceci :</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img width=\"478\" height=\"315\" decoding=\"async\" src=\"https://korben.info/app/uploads/2015/07/alc.jpg\" alt=\"\"/></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1253804088\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p><em>Article rédigé le 6 juillet 2015 et mis à jour le 15 décembre 2022.</em></p>\n",

Donc tant qu’à faire autant se protéger partout et finalement prendre ce VPN auquel vous pensez depuis des mois. Surtout qu’il y a encore en ce moment une petite promotion assez intéressante.</p>\n\n\n\n<p>C’est d’ailleurs par ça que je vais démarrer aujourd’hui, histoire de commencer l’article du bon pied. <strong><a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\" rel=\"noopener\">84% de réduction + 2 mois gratuit</a></strong>, ça a plutôt bien sa place sous le sapin non ? Moins de 55€ (+TVA) pour 26 mois de protection, et cela <strong>sur un nombre illimité d’appareils</strong> ! Difficile de faire mieux, pas encore d’inflation chez Surfshark 😉 Et comme toujours vous pouvez encore ajouter une couche de sécu supplémentaire avec le combo alertes + moteur de recherche + l’<a href=\"https://korben.info/surfshark-antivirus.html\" data-type=\"URL\" data-id=\"https://korben.info/surfshark-antivirus.html\">Antivirus Surfshark</a> (39€ pour les 26 semaines).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\"><img width=\"700\" height=\"87\" decoding=\"async\" src=\"https://me.korben.info/8ik-surfsharknoel\" alt=\"\"/></a></figure></div>\n\n\n<p>C’est le VPN que j’utilise personnellement et ce que j’apprécie c’est que depuis leur lancement (en 2018) ils évoluent sans cesse et plutôt vite. Il y a un mois c’était le lancement de <a href=\"https://korben.info/surfshark-nexus.html\" data-type=\"URL\" data-id=\"https://korben.info/surfshark-nexus.html\">Surfshark Nexus</a> par exemple, une fonctionnalité qui permet de stabiliser et améliorer la qualité de sa connexion. En ce mois de décembre, c’est au tour du service CleanWeb de subir une refonte et de passer au niveau supérieur.</p>\n\n\n\n<p>Pour rappel, l’option CleanWeb de base permet de bloquer les publicités et de vous protéger contre les malwares et autres tentatives de phishing. Avec la nouvelle mouture 2.0 les possibilités sont bien supérieures. Cette version n’est pour l’instant disponible que via les extensions pour navigateurs Firefox, Chrome et Edge. Donc sur Firefox. Les autres n’existant pas (bouh j’ai fais un troll sur mon site :p).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"320\" decoding=\"async\" src=\"https://media.giphy.com/media/9zgsLDswv632U/giphy.gif\" alt=\"\"/><figcaption class=\"wp-element-caption\"><em>j’en ai fait 2 du coup</em></figcaption></figure></div>\n\n\n<h2>Les options de <a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\" rel=\"noopener\">CleanWeb 2.0</a></h2>\n\n\n\n<p>Outre une nouvelle version du moteur de blocage des publicités, elle dispose d’une personnalisation et d’un affinage des blocages pour chacun site visité, etc. Cet affinage se fait sur 4 aspects (tous activés par défaut, mais modulable dans les paramètres) :</p>\n\n\n\n<ul>\n<li>le <strong>bloqueur de pubs</strong> : ne se limite plus seulement aux différentes bannières texte/image, il prend aussi en compte les encarts présents dans les vidéos ou sur les plateformes de streaming.</li>\n</ul>\n\n\n\n<ul>\n<li>le <strong>bloqueur de pop-up</strong> : va bloquer les ouvertures de fenêtres pop-up, incluant notamment les cookies de consentement/RGPD, etc. Par défaut il va les refuser automatiquement si c’est possible, sinon accepter uniquement les cookies obligatoires.</li>\n</ul>\n\n\n\n<ul>\n<li>les <strong>alertes malwares</strong> : vous prévient en cas de téléchargement risqué ou d’activité suspicieuse de la page sur laquelle vous êtes</li>\n</ul>\n\n\n\n<ul>\n<li>les <strong>alertes de fuite de données</strong></li>\n</ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"700\" height=\"500\" src=\"https://korben.info/app/uploads/2022/12/surfshark-cleanweb-2.jpg\" alt=\"\" class=\"wp-image-131803\" srcset=\"https://korben.info/app/uploads/2022/12/surfshark-cleanweb-2.jpg 700w, https://korben.info/app/uploads/2022/12/surfshark-cleanweb-2-300x214.jpg 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" /></figure></div>\n\n\n<p>Ces dernières sont vraiment intéressantes. Cela vous permet de savoir si les sites que vous visitez ont déjà eu des soucis par le passé. Et si c’est le cas, il vous fournit un tas d’informations : à quelle date, de quelle nature, le nombre de comptes concernés, etc. Pratique, car si l’un de ces sites à déjà plusieurs fuites à son actif, peut-être que cela vous fera réfléchir avant d’y laisser vos données personnelles. Ou bien la passoire qu’il semble être sera tellement énorme que vous bannirez ce site à vie par peur (<em>#coucouFacebook</em>).</p>\n\n\n\n<p>Vous pouvez aussi vous servir de ces informations comme d’un système de surveillance personnalisé. Si un service que vous utilisez se fait hacker sans que vous soyez au courant, vous verrez une alerte apparaitre dès que Surfshark aura vent du problème. Cela vous amènera sans doute à modifier votre mot de passe au plus vite.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"500\" height=\"210\" decoding=\"async\" src=\"https://media.giphy.com/media/EGe7H8HTtw3Cg/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Du coup <a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\" rel=\"noopener\">Surfshark</a> a décidé de lui donner une vraie place dans son interface avec une section dédiée sur le tableau de bord (c’était inclus dans la section VPN auparavant). D’ailleurs je le précise pour ceux qui se poseraient la question : <strong>CleanWeb fonctionne même sans être connecté au VPN</strong>, donc en permanence tant que vous utilisez votre navigateur (et que l’extension est active, Captain Obvious represent).</p>\n\n\n\n<p>Encore une bonne raison de plus pour se tourner vers Surfshark VPN !</p>\n\n\n\n<p>J’en profite pour vous rappeler que si vous n’êtes pas très chaud pour payer par carte bancaire ou Paypal, le site propose aussi les paiements Google Pay/Amazon Pay et même celui en cryptomonnaies (via les fournisseurs CoinGate et CoinPayments).</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" data-type=\"URL\" data-id=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\" rel=\"noreferrer noopener\">Profitez de l’offre hivernale à -84% + 2 mois gratuit</a></h2>\n",

Vous pouvez aussi rajouter une bordure à toutes vos images, modifier leur format et leur qualité (jpeg, web) ou encore les renommer avec le pattern de votre choix.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"485\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221112-87f.webp\" alt=\"\" class=\"wp-image-131371\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221112-87f.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221112-87f-300x142.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221112-87f-768x364.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Ensuite, une fois que tout est configuré, vous pouvez tout re-télécharger d’un coup, ou créer un zip que vous récupérerez. Très pratique comme site ! </p>\n\n\n\n<p></p>\n",

Et cela est possible grâce au script WebOSINT qui une fois en place sur votre machine, ira collecter toutes ces informations, soit directement, soit en utilisant certains services tiers.</p>\n\n\n\n<p>Pour que tout fonctionne correctement avec <a href=\"https://github.com/C3n7ral051nt4g3ncy/WebOSINT/blob/master/README.md\" target=\"_blank\" rel=\"noopener\">WebOSINT</a>, vous devrez donc vous créer des comptes sur différents services afin de récupérer les clés API.

Concernant l’<a href=\"https://whois.whoisxmlapi.com/\" target=\"_blank\" rel=\"noopener\">API WhoisXML</a> ou <a href=\"https://whoisfreaks.com/\" target=\"_blank\" rel=\"noopener\">WhoisFreaks</a>, il vous faudra par contre créer un compte, mais rassurez vous, c’est gratuit dans une certaine limite. WhoisXML se limite gratuitement à 500 recherches et WhoisFreaks à 100 recherches gratuites.</p>\n\n\n\n<p>Ensuite pour installer WebOSINT, ouvrez un terminal et entrez les commandes suivantes : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/C3n7ral051nt4g3ncy/webosint\ncd webosint\npip3 install -r requirements.txt\npython3 webosint.py</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1584905815\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Pensez à bien renseigner les clés API dans le fichier config.json. </p>\n\n\n\n<p>Une fois l’outil lancé, vous n’avez plus qu’à entrer le nom de domaine et laisser faire la magie de WebOSINT.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221109-e1i.webp\" alt=\"\" class=\"wp-image-131317\" width=\"662\" height=\"591\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221109-e1i.webp 840w, https://korben.info/app/uploads/2022/11/SCR-20221109-e1i-300x268.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221109-e1i-768x686.webp 768w\" sizes=\"(max-width: 662px) 100vw, 662px\" /></figure></div>\n\n\n<p>Merci à Deuza, <a href=\"https://www.patreon.com/korben\" target=\"_blank\" rel=\"noopener\">soutien Patreon de renom</a>, pour la découverte.</p>\n",

Elle a sorti un livre d’énigmes, il y a quelque temps, en collaboration avec son co-auteur Taharn, intitulé « La Clef » et j’avais envie de vous le faire découvrir.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/12/0f31d15798471097228db8b423cae8.webp\" alt=\"\" class=\"wp-image-131820\" width=\"610\" height=\"397\" srcset=\"https://korben.info/app/uploads/2022/12/0f31d15798471097228db8b423cae8.webp 1000w, https://korben.info/app/uploads/2022/12/0f31d15798471097228db8b423cae8-300x195.webp 300w, https://korben.info/app/uploads/2022/12/0f31d15798471097228db8b423cae8-768x499.webp 768w\" sizes=\"(max-width: 610px) 100vw, 610px\" /></figure></div>\n\n\n<p>C’est un livre unique en son genre (sérieux il n’y a pas d’équivalent !), qui combine une histoire passionnante et des énigmes complexes à résoudre grâce, notamment, à l’utilisation d’une lampe UV comme dans les Experts ^^.</p>\n\n\n\n<p>J’ai eu la chance de « tester » ce livre et j’ai vraiment été impressionnée par la qualité des illustrations qui m’ont plongé dans l’univers fantastique imaginé par Fanélia, ainsi que par l’originalité des énigmes proposées. Enfin, je dis « originalité », mais on encore au-delà de ça.</p>\n\n\n\n<p>Le livre s’appelle « La Clef » et c’est un ouvrage assez costaud, avec une couverture rigide et un papier d’une grande qualité, ce qui le classe dans la catégorie des livres de collection. Offrez-le à un(e) ami(e) geek et il ou elle vous aimera pour la vie ^^. Chaque double page du livre propose ainsi une énigme à résoudre, sans énoncé explicite. Oui, j’ai bien dit « sans énoncé », ce qui peut, je vous l’avoue être assez perturbant. En tout cas, moi ça me perturbe ^^.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/OK3.webp\" alt=\"\" class=\"wp-image-131815\" srcset=\"https://korben.info/app/uploads/2022/12/OK3.webp 1000w, https://korben.info/app/uploads/2022/12/OK3-300x225.webp 300w, https://korben.info/app/uploads/2022/12/OK3-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Le lecteur devra donc utiliser son sens de l’observation digne d’un aigle et sa logique implacable pour trouver la solution en se basant évidemment sur le texte et l’image. Le livre comporte 75 énigmes en tout, et certaines d’entre elles font référence à d’autres pages du livre ou <a href=\"https://www.laclef.online/concept/\" target=\"_blank\" rel=\"noopener\">même à des sites internet</a>. Vous imaginez le délire ?</p>\n\n\n\n<p>Un Discord est également disponible pour ceux qui souhaitent discuter des énigmes avec d’autres lecteurs et avoir un petit coup de pouce.</p>\n\n\n\n<p>L’un des aspects les plus intéressants du livre « La Clef », c’est l’utilisation de l’encre invisible. En utilisant la lampe UV fournie avec le livre, le lecteur peut ainsi découvrir des éléments cachés présents sur certaines pages. Ces indices viennent enrichir l’énigme et ajoutent un niveau à la complexité et à l’originalité des énigmes. Je vous promets que ça rend l’expérience de lecture encore plus immersive et divertissante.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/OK5.webp\" alt=\"\" class=\"wp-image-131816\" srcset=\"https://korben.info/app/uploads/2022/12/OK5.webp 1000w, https://korben.info/app/uploads/2022/12/OK5-300x225.webp 300w, https://korben.info/app/uploads/2022/12/OK5-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/OK6.webp\" alt=\"\" class=\"wp-image-131817\" srcset=\"https://korben.info/app/uploads/2022/12/OK6.webp 1000w, https://korben.info/app/uploads/2022/12/OK6-300x225.webp 300w, https://korben.info/app/uploads/2022/12/OK6-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Concernant l’univers du livre, je vais tenter de vous résumer ce que j’en ai compris. Ça se passe à Astolie, un monde imaginaire dans un style purement Dark Fantasy et le lecteur peut comme ça, découvrir les différents aspects de la mythologie et de la culture d’Astolie en résolvant les énigmes. </p>\n\n\n\n<p>Chaque énigme est plus originale que la précédente, et certaines font même référence à d’autres oeuvres de la littérature, du cinéma ou des jeux vidéo. Cela permet aux fans d’énigmes de retrouver des références qu’ils connaissent bien, tout en découvrant le nouvel univers tout droit sorti de la tête de nos auteurs.</p>\n\n\n\n<p>Je l’ai déjà dit, mais les énigmes sont assez complexes, et elles ne sont pas vraiment destinées aux débutants. Ce n’est pas un livre d’énigmes bas de gamme pour s’occuper à la plage comme on peut en trouver parfois… Non, non, elles nécessitent une réflexion approfondie et une capacité à associer des éléments divers et variés pour trouver la solution. Cela en fait le livre parfait pour les amateurs d’énigmes expérimentés ou les gens à l’esprit acéré, cherchant un défi stimulant et original. Je sais, chacun d’entre nous pense qu’il a l’esprit vif et qu’il est plus malin que son voisin… Je vous rassure, ce livre vous aidera à voir la réalité en face, et ça va faire mal ^^.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/OK4.webp\" alt=\"\" class=\"wp-image-131818\" srcset=\"https://korben.info/app/uploads/2022/12/OK4.webp 1000w, https://korben.info/app/uploads/2022/12/OK4-300x225.webp 300w, https://korben.info/app/uploads/2022/12/OK4-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Mon retour sur le bouquin, c’est que je l’adore, mais, la vache, je galère. C’est plus dur qu’un challenge de hacking 😉 en tout cas, je suis loin de l’avoir fini.</p>\n\n\n\n<p>Les fans d’univers fantastique ou de Fantasy apprécieront également la qualité des illustrations et l’ambiance immersive créée par Fanelia. D’ailleurs, si vous appréciez ses dessins, sachez qu’elle vend également ses oeuvres sur son site.</p>\n\n\n\n<p>Pour conclure, je dirais que « La Clef » est un bouquin original et passionnant qui mérite d’être lu par les amateurs d’énigmes et d’univers fantastiques n’ayant pas peur de se prendre un peu la tête. Tout est qualitatif dans ce livre et les énigmes + l’utilisation de l’encre invisible, en font un livre à la fois beau et stimulant pour notre petit cerveau tout mou. Ça change !</p>\n\n\n\n<p>La complexité des énigmes et la richesse de l’univers d’Astolie en feront un cadeau idéal pour vos amis ou votre famille, en particulier à l’approche de Noël. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/OK2.webp\" alt=\"\" class=\"wp-image-131814\" srcset=\"https://korben.info/app/uploads/2022/12/OK2.webp 1000w, https://korben.info/app/uploads/2022/12/OK2-300x225.webp 300w, https://korben.info/app/uploads/2022/12/OK2-768x576.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Si vous êtes intéressé, vous pouvez <a href=\"https://amzn.to/3BeZiYk\" target=\"_blank\" rel=\"noopener\"><strong>le commander en ligne</strong></a> ou le trouver dans une librairie spécialisée ou directement <strong><a href=\"https://www.fanelia.art/22-la-clef\" target=\"_blank\" rel=\"noopener\">sur le site de Fanéli</a></strong><a href=\"https://www.fanelia.art/22-la-clef\" target=\"_blank\" rel=\"noopener\"><strong>a</strong></a>.</p>\n\n\n\n<p>Encore merci à Fanelia de m’avoir fait découvrir Astolie !</p>\n",

Pour cela, un script nommé Lama Cleaner permet de faire ça très facilement. </p>\n\n\n\n<p>Pour l’installer, ouvrez un terminal et entrez la commande pip ou pipx suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>pip install lama-cleaner</code></pre>\n\n\n\n<p>Une fois que c’est installé, lancez lama cleaner comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>lama-cleaner --model=lama --device=cpu --port=8080</code></pre>\n\n\n\n<p>Si vous avez un GPU avec Cuda, vous pouvez également remplacer –device=cpu par –device=cuda.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1922593520\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Et pour utiliser le modèle de Stable Diffusion, il vous faudra accepter <a rel=\"noopener\" href=\"https://huggingface.co/runwayml/stable-diffusion-inpainting\" target=\"_blank\">les conditions d’huggingface ici</a> et générer <a rel=\"noopener\" href=\"https://huggingface.co/settings/tokens\" target=\"_blank\">une clé API</a> à utiliser comme ceci : </p>\n\n\n\n<pre class=\"wp-block-preformatted\">lama-cleaner --model=sd1.5 --device=cpu --hf_access_token=hf_xxxxxxxxxxxxxxxxxxxxxxxxx</pre>\n\n\n\n<p>Une url vous sera alors communiquée. Ouvrez là dans votre navigateur : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>http://127.0.0.1:8080/</code></pre>\n\n\n\n<p>Ensuite, uploadez votre photo et utilisez le pinceau pour supprimer ce qui vous chante. Dans les paramètres vous pouvez changer de modèle mais également activer l’option ‘Manuel Inpainting Mode’ pour avoir une icone de gomme permettant de lancer le traitement.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221107-fd4.webp\" alt=\"\" class=\"wp-image-131262\" width=\"659\" height=\"458\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221107-fd4.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221107-fd4-300x209.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221107-fd4-768x535.webp 768w\" sizes=\"(max-width: 659px) 100vw, 659px\" /></figure></div>\n\n\n<p>Par exemple, j’ai fait une jolie photo de mon salon, mais y’a mon chat qui est venu tout gâcher avec ses petites fesses.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221107-fy3.webp\" alt=\"\" class=\"wp-image-131263\" width=\"523\" height=\"556\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221107-fy3.webp 723w, https://korben.info/app/uploads/2022/11/SCR-20221107-fy3-282x300.webp 282w\" sizes=\"(max-width: 523px) 100vw, 523px\" /></figure></div>\n\n\n<p>Alors hop, nettoyage du chat et voilà !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221107-k84.webp\" alt=\"\" class=\"wp-image-131265\" width=\"527\" height=\"725\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221107-k84.webp 558w, https://korben.info/app/uploads/2022/11/SCR-20221107-k84-218x300.webp 218w\" sizes=\"(max-width: 527px) 100vw, 527px\" /></figure></div>\n\n\n<p>Et si vous utilisez le modèle de Stable Diffusion, vous pouvez remplacer ce que vous coloriez par un autre truc.

Bref tous ceux qui vendent ou utilisent de la publicité personnalisée. Et malheureusement ces infos finissent toujours par fuiter ou être revendues. GAFAM, application mobile ou petit site e-commerce, pas une semaine ne passe sans que l’un de ces services subisse un leak ou un piratage quelconque. Certains sont même créées quasiment juste pour cela, par exemple des applis spéciales pour profiter des offres du Black Friday qui revendent vos données une fois la période terminée.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"800\" height=\"426\" decoding=\"async\" src=\"https://me.korben.info/19u-incogni3\" alt=\"\"/></figure></div>\n\n\n<p>Dans 91.24% des cas (estimation personnelle scientifiquement validée et basée sur mon flair digne de Rantanplan), cela se fait à votre insu. Vous recevez parfois un mail ou un SMS louche pour lequel vous vous demandez comment les gens ont eu vos coordonnées, mais le plus souvent c’est flou ou vous l’acceptez comme allant de soi. Quoi de plus normal que la publicité ciblée et basée sur nos préférences ? Vous commencez dans les cryptos et n’avez encore jamais interagi avec ces services ? Combien de temps avant de recevoir des mails de phishing Metamask & Co ? Pas très longtemps dans la plupart des cas.</p>\n\n\n\n<p>Dès que votre mail, votre numéro de téléphone, votre nom … est lié à un centre d’intérêt particulier vous êtes foutu, ça va tourner dans des dizaines de bases de données chez les data brokers. Vous devez alors leur demander de les retirer. Selon les pays ils sont parfois légalement tenus de le faire, mais même dans ce cas ils traineront des pieds au maximum, car c’est leur gagne-pain. Et il faut déjà commencer par les identifier, ce qui n’est pas souvent simple à faire. Bonjour les maux de tête.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://media.giphy.com/media/YpmVBNubONoqs/giphy.gif\" alt=\"\" width=\"400\" height=\"224\"/></figure></div>\n\n\n<p><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Incogni est là</a> pour faire le travail à votre place.</p>\n\n\n\n<p>En utilisant le service, vous allez commencer par lui renseigner les différentes informations que vous voulez faire retirer d’Internet. Ensuite Incogni prend tout en charge. Ils vont analyser en continu qui sont les data brokers possédant vos infos et leur demander de les effacer. Pour l’instant plus de 145 brokers sont surveillés et la liste s’allonge chaque mois (ils n’en suivaient que 76 au lancement du produit il y a quelques mois). Si ces derniers ne répondent pas, ils vont les relancer sans arrêt et augmenter la pression jusqu’à ce que ce soit fait. Et même lorsque c’est retiré ils vont continuer à surveiller que cela reste bien le cas. Un peu comme si vous vous mettiez sur liste rouge du web.</p>\n\n\n\n<p>Incogni annonce sauver environ 300 heures de travail. J’imagine que c’est dans le cas où vous seriez présent sur tous les data brokers qu’ils surveillent et je ne peux pas vérifier cette info, mais quand même. Cela en fait du temps gagné et vous suivrez l’évolution de la situation via un tableau de bord régulièrement mis à jour. Vous pouvez y voir le nom des sociétés qui détiennent vos informations, ce qu’elles en font, où en est la procédure de suppression et parfois à qui elles communiquent leurs données. Voir <a href=\"https://korben.info/incogni-test.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-test.html\">mon test d’Incogni</a> si vous voulez voir à quoi ça ressemble.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"800\" height=\"414\" src=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg\" alt=\"\" class=\"wp-image-130591\" srcset=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg 800w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-300x155.jpg 300w, https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord-768x397.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" /></figure></div>\n\n\n<p>En résumé Incogni agit comme un intermédiaire. Ce n’est pas qu’ils font quelque chose que vous ne pourriez faire vous-mêmes, ils sont plutôt là pour vous faire gagner du temps et que vous n’ayez pas à recommencer le travail tous les x mois. Comparé à d’autres outils du même genre les tarifs sont plutôt bas puisqu’ils sont de l’ordre de moins de 5.8€/mois sur l’abonnement à l’année.</p>\n\n\n\n<blockquote class=\"wp-block-quote\">\n<p>Et puisque ce sont bientôt les fêtes, voici déjà un bon plan qui pourrait vous faire plaisir. Profitez d’une<strong> offre à -60 % sur l’abonnement d’un an à Incogni</strong> en ajoutant le code INCOGNI60 lors de votre commande !! Vous avez jusqu’au 4 décembre alors ne tardez pas !</p>\n</blockquote>\n\n\n\n<p>Si vous avez comme plan de disparaitre virtuellement bientôt, c’est peut-être un outil qui vous rendra quelques services 😉 Enfin si vous habitez en Europe (inclus l’Angleterre), aux USA, en Suisse ou au Canada. Pour les autres pays, ce n’est pas encore pris en charge.</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Incogni, efface-moi d’Internet stp !</a></h2>\n",

Vous ne les connaissez peut-être pas encore et pourtant, 3CX s’occupe de la communication de plus 600 000 clients, le tout dans 190 pays différents, pour un total très impressionnant de 12 millions d’utilisateurs. 3CX est d’ailleurs la solution retenue par Mac Donald, Somfy, Air France, Toyota ou encore Pepsi.</p>\n\n\n\n<p>Bref, vous l’aurez compris, ils font partie des leaders de leur secteur et maîtrisent parfaitement les sujets liés à la <strong>VoIP / WebRTC</strong>. Et si je vous en parle aujourd’hui, c’est pour vous présenter leur <strong>offre StartUP</strong> qui a la particularité d’être <strong>totalement gratuite</strong>.</p>\n\n\n\n<h2><a href=\"https://www.3cx.fr/startup/?src=korben-fr\" target=\"_blank\" rel=\"noopener\">Votre standard téléphonique pour 0 € / mois</a></h2>\n\n\n\n<p>Cette offre permet aux indépendants comme moi, mais également aux sociétés de moins de 10 personnes, de disposer d’une plateforme de communication interne hyper complète et évidemment de qualité. Cela vous permettra de communiquer rapidement et facilement avec vos collaborateurs, vos clients et même les internautes de passage sur votre site web. </p>\n\n\n\n<p>Très pratique si vous êtes une startup ou une PME qui met à disposition un numéro de téléphone ou qui dispose d’un webchat sur son site web pour répondre à toutes les demandes de ses clients. Je pense notamment à tous les e-commerçants ou les startups naissantes qui n’ont pas encore les moyens des grosses entreprises.</p>\n\n\n\n<p>C’est pour cela que 3CX propose une solution de standard téléphonique et de plateforme de messagerie gérée par leurs soins et dans certains cas, hébergée sur vos propres serveurs.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://me.korben.info/8874b5-3CX\" alt=\"\" width=\"625\" height=\"300\"/></figure></div>\n\n\n<p><a rel=\"noopener\" href=\"https://www.3cx.fr/startup/?src=korben-fr\" target=\"_blank\"><strong>L’offre StartUP Free</strong></a> est donc un bon moyen de découvrir les possibilités de la plateforme de 3CX sans débourser un centime. Je vous propose qu’on passe en revue toutes les possibilités de cette offre.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"508\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-dkb.webp\" alt=\"\" class=\"wp-image-131524\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-dkb.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221122-dkb-300x149.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221122-dkb-768x381.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>En vous rendant sur leur site, vous pouvez donc vous créer un compte en quelques secondes et ainsi avoir votre plateforme 3CX cloud rien qu’à vous. Vous en serez le manager et vous pourrez alors ajouter des utilisateurs qui recevront à leur tour un email qui leur expliquera comment se connecter à la plateforme.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-dm6Z.webp\" alt=\"\" class=\"wp-image-131534\" width=\"599\" height=\"331\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-dm6Z.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221122-dm6Z-300x166.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221122-dm6Z-768x425.webp 768w\" sizes=\"(max-width: 599px) 100vw, 599px\" /></figure></div>\n\n\n<h2>Découvrez l’interface de 3CX</h2>\n\n\n\n<p>À partir de là, vous pouvez créer un groupe d’appel qui rassemblera toutes les personnes habilitées à répondre au téléphone. Une stratégie de groupe est alors possible pour que lorsqu’un appel entrant arrive, il soit basculé aux membres du groupe. C’est un véritable standard VoIP qui vous permettra de recueillir tous les appels entrants liés à votre business.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"729\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-f2d.webp\" alt=\"\" class=\"wp-image-131526\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-f2d.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221122-f2d-300x214.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221122-f2d-768x547.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Chaque appel est placé en liste d’attente pendant un certain moment, avec la musique et le message vocal de votre choix, et si personne ne décroche pendant un certain temps, les appels peuvent alors être terminés, renvoyés vers un autre groupe, ou basculés vers un répondeur…etc. Finie la frustration d’entendre un numéro de téléphone qui sonne occupé. Vous accueillez vos clients comme il se doit.</p>\n\n\n\n<p>Bref, de quoi gérer votre propre petit standard téléphonique gratuitement et surtout facilement, car l’interface est vraiment très propre et très claire. Pas besoin d’être technicien pour se l’approprier.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/webclient_apps.webp\" alt=\"\" class=\"wp-image-131541\" width=\"686\" height=\"387\" srcset=\"https://korben.info/app/uploads/2022/11/webclient_apps.webp 1024w, https://korben.info/app/uploads/2022/11/webclient_apps-300x169.webp 300w, https://korben.info/app/uploads/2022/11/webclient_apps-768x434.webp 768w\" sizes=\"(max-width: 686px) 100vw, 686px\" /></figure></div>\n\n\n<h2>Les applications clientes</h2>\n\n\n\n<p>En termes d’interface, vous pouvez passer via le navigateur avec l’interface web ou via l’une des applications Desktop (Windows, macOS) ou mobile (iOS, Android), ce qui est vraiment super pratique si vous utilisez 3CX toute la journée ou si vous êtes en déplacement avec votre seul smartphone.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-dtr.webp\" alt=\"\" class=\"wp-image-131535\" width=\"317\" height=\"490\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-dtr.webp 497w, https://korben.info/app/uploads/2022/11/SCR-20221122-dtr-194x300.webp 194w\" sizes=\"(max-width: 317px) 100vw, 317px\" /></figure></div>\n\n\n<p>La configuration de l’application mobile est également très simple puisqu’une fois installée, il suffit de scanner un QR Code reçu par email pour valider la configuration.</p>\n\n\n\n<h2>La visioconférence</h2>\n\n\n\n<p>Ensuite, vous pourrez sans soucis passer et recevoir des appels, mais surtout organiser des Visio-conf, des webinaires…etc. et y participer. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-ljr.webp\" alt=\"\" class=\"wp-image-131537\" width=\"538\" height=\"467\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-ljr.webp 883w, https://korben.info/app/uploads/2022/11/SCR-20221122-ljr-300x261.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221122-ljr-768x668.webp 768w\" sizes=\"(max-width: 538px) 100vw, 538px\" /></figure></div>\n\n\n<p>Tout se fait très simplement avec la création d’un email d’invitation contenant un lien, que chaque participant reçoit. En cliquant dessus, le moment venu, il rejoindra alors la réunion avec ou sans application. Vous pourrez alors vous voir, discuter et même échanger des documents ou faire une présentation à distance. Rien de plus simple.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/video-conference-call.webp\" alt=\"\" class=\"wp-image-131540\" width=\"519\" height=\"298\" srcset=\"https://korben.info/app/uploads/2022/11/video-conference-call.webp 1024w, https://korben.info/app/uploads/2022/11/video-conference-call-300x173.webp 300w, https://korben.info/app/uploads/2022/11/video-conference-call-768x442.webp 768w\" sizes=\"(max-width: 519px) 100vw, 519px\" /></figure></div>\n\n\n<p>Vous pourrez ainsi gérer un planning d’appels ou de réunions et suivre tout votre historique de communication. Très pratique si vous faites de la prospection par exemple.</p>\n\n\n\n<h2>La messagerie LiveChat & WhatsApp</h2>\n\n\n\n<p>La messagerie interne de la plateforme est également un moyen très pratique de discuter entre collègues pour gérer le quotidien. Mais c’est surtout pour proposer un canal de communication type SMS à vos clients que l’offre de 3CX devient intéressante. Vous pourrez par exemple proposer une interaction via <strong>WhatsApp</strong> à vos clients, simplement avec l’offre StartUP Free.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-lul.webp\" alt=\"\" class=\"wp-image-131539\" width=\"434\" height=\"473\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-lul.webp 705w, https://korben.info/app/uploads/2022/11/SCR-20221122-lul-275x300.webp 275w\" sizes=\"(max-width: 434px) 100vw, 434px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-fa0.webp\" alt=\"\" class=\"wp-image-131528\" width=\"739\" height=\"366\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-fa0.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221122-fa0-300x149.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221122-fa0-768x381.webp 768w\" sizes=\"(max-width: 739px) 100vw, 739px\" /></figure></div>\n\n\n<p>Même chose pour la partie <strong>LiveChat</strong> qui peut être déployée sur n’importe quel site web notamment <strong>WordPress</strong>, à l’aide d’un plugin très simple à configurer. Cela permettra aux internautes qui se connectent sur votre site de discuter par messagerie avec vos collaborateurs.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221122-eyq.webp\" alt=\"\" class=\"wp-image-131536\" width=\"596\" height=\"633\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221122-eyq.webp 723w, https://korben.info/app/uploads/2022/11/SCR-20221122-eyq-282x300.webp 282w\" sizes=\"(max-width: 596px) 100vw, 596px\" /></figure></div>\n\n\n<h2>Une solution qui s’intègre à vos outils</h2>\n\n\n\n<p>Évidemment, toute la solution de 3CX s’intègre parfaitement avec des outils comme Microsoft 365 ou Salesforce ainsi que d’autres CRM. Cela vous permettra d’avoir un suivi des conversations avec votre clientèle.</p>\n\n\n\n<p>Chaque membre du groupe peut également paramétrer ses heures de présence pour que le standard sache où et quand renvoyer les appels. C’est plutôt génial d’avoir un outil totalement VoIP comme celui-ci qui peut être parfaitement utilisé par les gens en télétravail.</p>\n\n\n\n<h2>Conclusion</h2>\n\n\n\n<p>3CX a vraiment fait du très bon travail. Comme je le disais, l’outil est simple à prendre en main, même pour le néophyte et chacun peut alors bénéficier d’un standard VoIP gratuitement. Les visioconférences et les appels téléphoniques sont parfaitement fluides et d’un bon niveau de qualité, mais surtout, ce qui fait la force de 3CX c’est vraiment l’implémentation de ces technologies (VoIP / WebRTC) dans une suite qui offre toutes les fonctionnalités nécessaires aux petites, moyennes et grandes entreprises qui ont des besoins de communication clientèle. De plus, les fonctionnalités de messagerie que ce soit via WhatsApp ou Livechat, en intégration sur un site web, sont idéales pour recueillir les échanges clients en réduisant les temps d’attente et les temps d’échange.</p>\n\n\n\n<p>Bref, c’est vraiment un outil à essayer si vous avez besoin de mettre en place un live chat ou un standard téléphonique. </p>\n\n\n\n<h2 class=\"has-text-align-center\"><strong><a href=\"https://www.3cx.fr/startup/?src=korben-fr\" target=\"_blank\" rel=\"noopener\">Pour vous inscrire, c’est par ici</a></strong></h2>\n\n\n\n<p>Et si vous avez besoin de documentation, <a href=\"https://www.3cx.fr/docs/startup/?src=korben-fr\" target=\"_blank\" rel=\"noreferrer noopener\">celle-ci se trouve ici</a>.</p>\n",

Seulement voilà, malgré tout l’amour que vous portez à Firefox, vous restez quand même conscient que parfois, il peut bouffer un peu *trop* de mémoire. Surtout quand on le laisse ouvert pendant des jours et des jours, il suffit d’une petite fuite mémoire, pour que ça devienne la cata.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-497820175\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>C’est là qu’arrive à la rescousse Firemin, un utilitaire gratuit qui est capable de libérer la mémoire non utilisée de Firefox. Alors c’est vrai que Windows sait également nettoyer la mémoire, mais il ne le fait pas aussi souvent que Firmin qui lui veille particulièrement sur Firefox.</p>\n\n\n\n<p>Une fois Firemin lancé, vous choisissez une fréquence de « nettoyage » en millisecondes (par défaut c’est 1000 ms), mais les développeurs de Firemin indiquent que les résultats seront meilleurs avec 500 ms. Vous pouvez également spécifier une quantité de mémoire propre à Firefox, à ne pas dépasser (ici 100 MB).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221104-a26-2.webp\" alt=\"\" class=\"wp-image-131157\" width=\"433\" height=\"508\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221104-a26-2.webp 655w, https://korben.info/app/uploads/2022/11/SCR-20221104-a26-2-256x300.webp 256w\" sizes=\"(max-width: 433px) 100vw, 433px\" /></figure></div>\n\n\n<p>Là où c’est sympa, c’est que vous pouvez lui indiquer d’autres navigateurs (Chrome, Brave, Edge…etc.) en cliquant simplement sur le bouton « Parcourir ». J’imagine que ça peut fonctionner également avec d’autres applications qui ne sont pas des navigateurs, donc à essayer sur vos applications consommatrices de mémoire.</p>\n\n\n\n<p>L’outil doit être lancé en même temps que le navigateur pour fonctionner, donc pensez bien à cocher la case « Démarrer Firemin quand Windows démarre » pour ensuite l’oublier. Firemin est dispo également en version portable.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-642531644\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Je sais que ce genre d’outils, c’est un peu comme l’homéopathie, donc à vous de l’essayer et de voir si vous voyez une amélioration ou pas.

Mais il y a aussi la stabilité de votre ligne ADSL, de votre Fibre ou de votre connexion 4G/5G qui est importante. </p>\n\n\n\n<p>Une connexion avec beaucoup de bande passante, c’est cool pour regarder une vidéo en ligne ou télécharger un fichier, mais pour des activités moins gourmandes comme la visioconférence ou les jeux vidéos, ce qui compte surtout c’est que les réponses à vos requêtes soient rapides et fiables.</p>\n\n\n\n<p>Si vos requêtes ne parviennent pas à leur destination, les paquets sont alors perdus et cela peut dégrader votre expérience de jeu par exemple. Sur du FPS, pour être bien il faudrait que le ping soit à minima bien en dessous des 60ms et qu’il n’y ait aucun paquet perdu.</p>\n\n\n\n<p>Même chose pour les visioconférences ou la VoIP, vous devez avoir quelque chose de bon niveau ping et une certaine régularité dans l’arrivée de vos paquets TCP pour que la discussion reste compréhensible.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-991969282\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Alors, comment évaluer ça ? Et bien rendez-vous sur le site <a href=\"https://packetlosstest.com/\" target=\"_blank\" rel=\"noopener\">Packet Loss Test</a> pour mesurer la fiabilité de votre connexion, et déterminer à la fois la latence, mais également le pourcentage de paquets perdus.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221022-axy.webp\" alt=\"\" class=\"wp-image-131060\" width=\"717\" height=\"405\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221022-axy.webp 1024w, https://korben.info/app/uploads/2022/10/SCR-20221022-axy-300x170.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221022-axy-768x435.webp 768w\" sizes=\"(max-width: 717px) 100vw, 717px\" /></figure></div>\n\n\n<p>De mon côté, je suis plutôt pas mal. Si de votre côté, vous avez beaucoup de paquets perdus, ce n’est pas forcément la faute de votre FAI. Jouez avec les réglages du site pour adapter le test à votre bande passante maximale.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"617\" height=\"768\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221022-ayw.webp\" alt=\"\" class=\"wp-image-131061\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221022-ayw.webp 617w, https://korben.info/app/uploads/2022/10/SCR-20221022-ayw-241x300.webp 241w\" sizes=\"(max-width: 617px) 100vw, 617px\" /></figure></div>\n\n\n<p>Et si ça ne change rien, il est fort probable que vous ayez sur votre réseau local, un routeur ou une carte réseau qui se comporte mal. Il faudra alors jouer au jeu du « <em>Je te débranche, je re-teste et je vois si ça va mieux</em>« .</p>\n\n\n\n<p>Enfin, si rien ne cloche, un petit coup de fil au fournisseur d’accès internet. Bon courage avec cette dernière étape.</p>\n",

Ou en français, un courtier en données ? Pas vraiment ? Pourtant je suis presque certain que vous en avez forcément rencontré un dans votre vie sur Internet, voire plusieurs. Ils pullulent tellement qu’il est aujourd’hui presque impossible de conserver son existence en ligne pour soi. Vos informations sont récupérées et exploitées chez eux. Malheureusement, malgré les dangers qu’ils représentent pour les gens, physiquement et virtuellement, tout le monde ne les connait pas.</p>\n\n\n\n<p>Un courtier en données est un <s>parasite</s> organisme qui récolte des informations personnelles sur le maximum d’internautes. Ils compilent leurs différentes sources pour créer un profil plus ou moins précis de vous en recoupant ce qu’ils trouvent. Cela va de votre email, à votre adresse, vos noms et prénoms, vos possessions, vos informations légales … voir vos habitudes d’achat et votre historique web.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"800\" height=\"368\" decoding=\"async\" src=\"https://me.korben.info/xcj-incogni2\" alt=\"\"/></figure></div>\n\n\n<p>Où vont-ils chercher ces données ? Et bien déjà de tout ce qui est public par défaut (infos perso lorsque vous créez une société …) ou partagé publiquement par vous-mêmes (réseaux sociaux …). Ensuite parce que certains services peu scrupuleux sur lesquels vous vous inscrivez n’hésitent pas à les revendre (par exemple votre numéro de carte bancaire que vous avez inséré dans un jeu mobile). Plus de 40% des extensions Chrome sont classées comme <a rel=\"noreferrer noopener\" href=\"https://blog.incogni.com/chrome-extensions-research/\" data-type=\"URL\" data-id=\"https://blog.incogni.com/chrome-extensions-research/\" target=\"_blank\">étant à risque</a>. Enfin depuis des bases de données, des listes de clients, etc. volées, leakées ou revendues par divers hackeurs.</p>\n\n\n\n<p>Une fois qu’ils ont recoupé et centralisé toutes leurs sources, ils vont établir des profils thématisés et revendre à leur tour ces informations à des entités commerciales. Vous venez de divorcer ? Vous allez subitement recevoir de la pub en rapport. Une partie des spams que vous recevez dans votre boite mail, ce sont eux. Des SMS non sollicités ? Encore eux. Des coups de fil intempestifs ? Toujours eux.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://media.giphy.com/media/xdnytp8742kg0/giphy.gif\" alt=\"\" width=\"300\" height=\"188\"/></figure></div>\n\n\n<p>Non seulement c’est pénible, mais en plus cela peut être dangereux. Certains sites web centralisent les infos et n’hésitent pas à les rendre accessibles à tous. Il suffit alors d’une recherche sur votre nom pour connaitre éventuellement votre adresse physique, l’endroit ou vous travaillez, quelle voiture vous conduisez, si vous possédez une assurance vie ou non, qui sont les membres de votre famille, etc. Heureusement pour cet aspect « porte ouverte au grand public » nous avons certaines protections en France, <a href=\"https://korben.info/incogni-rgpd.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-rgpd.html\">notamment le RGPD</a>. Mais aux USA il y a des sites comme PeekYou, WhitePages, etc. qui les partagent. Et c’est flippant.</p>\n\n\n\n<p>Du coup l’idéal c’est de faire supprimer tout ce qui permet de vous identifier chez ces data brokers. Mais comment faire ? Comment identifier ces courtiers ? Et comment savoir qu’un courtier détient vos infos ? Enfin, comment lui faire supprimer ce qu’il possède sur vous ?</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"800\" height=\"267\" src=\"https://korben.info/app/uploads/2022/11/incogni-dashboard.jpg\" alt=\"incogni Dashboard\" class=\"wp-image-131464\" srcset=\"https://korben.info/app/uploads/2022/11/incogni-dashboard.jpg 800w, https://korben.info/app/uploads/2022/11/incogni-dashboard-300x100.jpg 300w, https://korben.info/app/uploads/2022/11/incogni-dashboard-768x256.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" /></figure></div>\n\n\n<p>Ne vous cassez plus le cerveau, <a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Incogni est là pour vous faciliter la vie</a>. Pour quelques euros par mois, le service de Surfshark va scanner tout le web pour :</p>\n\n\n\n<ul>\n<li>retrouver les brokers qui disposent de vos infos personnelles</li>\n\n\n\n<li>contacter ces courtiers pour leur demander de les supprimer (ce qui est votre droit)</li>\n\n\n\n<li>relancer ces derniers s’ils ne se bougent pas assez vite</li>\n\n\n\n<li>effectuer un suivit au fil du temps pour s’assurer que vos infos ne sont pas remises en ligne</li>\n</ul>\n\n\n\n<p>Et comme Incogni augmente sans cesse sa liste de brokers sous surveillance, plus le temps passe et plus votre protection augmente. Je vous ai fait un<a href=\"https://korben.info/incogni-test.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-test.html\"> test du service complet </a>il y a quelques semaines, j’avais été plutôt étonné de voir le nombre de courtiers qui m’avaient sous la main (quasi 100 !). Au moins, filez-moi un billet pour exploiter mes données bande de crevards. Surtout au vu des prix auxquels elles se revendent parfois.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://media.giphy.com/media/6u1Z9pUakUHG6o7oiV/giphy.gif\" alt=\"\" width=\"540\" height=\"303\"/></figure></div>\n\n\n<p>Bref avec Incogni vous allez économiser pas mal de temps, de maux de tête et d’énervement lorsque les data brokers ignorerons vos mails. Non, mais qui êtes-vous pour leur retirer le pain de la bouche aussi ? L’autre gros avantage du service est de vous présenter un suivit via un tableau de bord très simple à prendre en main. Vous verrez combien de brokers ont vos infos et suivrez en temps réel l’avancée du retrait de vos données. Ainsi que le travail de sape d’Incogni pour les relancer sans cesse jusqu’à ce qu’ils obtempèrent.</p>\n\n\n\n<p>Une corde de plus à l’arc du respect de la vie privée sur Internet. C’est toujours bon à prendre.</p>\n\n\n\n<blockquote class=\"wp-block-quote\">\n<p>Commencez la saison des fêtes avec un peu plus de tranquillité d’esprit ! Protégez vos données personnelles et profitez d’une réduction de 60 % sur l’abonnement d’un an à Incogni.

Si vous ne connaissez pas le concept de Serverless, et bien ça va être vite résumé : C’est héberger des trucs directement dans le cloud (chez Amazon par exemple), sans avoir ni serveur dédié ni serveur virtualité.</p>\n\n\n\n<p>Quand on est développeur, on peut vite rester bloqué sur les technologies qu’on connait par coeur. Toutefois, c’est dommage de ne pas continuer à découvrir de nouvelles pratiques ou technologies, car si demain. C’est important si vous souhaitez évoluer dans la carrière de vos rêves.</p>\n\n\n\n<p>C’est d’ailleurs pour ça que le <a rel=\"noopener\" href=\"https://www.talent.io/p/fr-fr/talent-club?utm_source=korben&utm_medium=partnership&utm_campaign=Q4&utm_content=article\" target=\"_blank\"><strong>talent club</strong></a> a été crée. Il s’agit d’une communauté tech propulsée par talent.io qui donne accès à du contenu exclusif pour vous accompagner professionnellement. En vous inscrivant (<strong>c’est gratuit !!</strong>), vous recevrez tous les 15 jours des conseils d’expert(e)s de sociétés comme Google, Deezer, Sorabe…etc. directement dans votre boite mail. Les sujets partagés sont assez variés comme « Comment devenir VP of Engineering », « Comment passer du dev au produit », « Comment obtenir une augmentation », « quelles sont les choses à savoir quand on est le 1er dev d’une start-up », etc..</p>\n\n\n\n<p>Au sein du talent club, vous aurez aussi accès aux <strong>études de salaires annuelles dans la tech</strong> réalisées par <a rel=\"noopener\" href=\"https://www.talent.io/p/fr-fr/talent-club?utm_source=korben&utm_medium=partnership&utm_campaign=Q4&utm_content=article\" target=\"_blank\">talent.io</a> et à d’autres outils pour gérer votre carrière</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><a href=\"https://www.talent.io/p/fr-fr/talent-club?utm_source=korben&utm_medium=partnership&utm_campaign=Q4&utm_content=article\"><img decoding=\"async\" loading=\"lazy\" src=\"https://me.korben.info/fuy-serverless-talentio\" alt=\"\" width=\"479\" height=\"378\"/></a></figure></div>\n\n\n<p>Et bien sûr qui dit communauté, dit possibilité de poser des questions à l’ensemble des 40 000 inscrits, de manière anonyme. <a href=\"https://www.talent.io/p/fr-fr/talent-club?utm_source=korben&utm_medium=partnership&utm_campaign=Q4&utm_content=article\" target=\"_blank\" rel=\"noopener\">Je vous invite à rejoindre la communauté talent club en cliquant ici</a>.</p>\n\n\n\n<p>Revenons à notre code et prenons un bout de PHP. Pour le faire fonctionner, vous avez besoin de louer, configurer, et maintenir un serveur. Et évidemment si ce bout de code PHP reçoit beaucoup de trafic, vous devrez aussi augmenter le nombre de serveurs ou libérer des ressources…</p>\n\n\n\n<p>Le serverless, ça permet d’éviter cela et donc de réduire les coûts opérationnels, aussi bien en termes d’hébergement, que de maintenance…etc. Et surtout, comme on se repose sur les infrastructures de géants comme Google, Microsoft ou Amazon, ça ne tombe *jamais* en panne et ça peut être scalable (mise à l’échelle pour absorber le trafic) très simplement.?</p>\n\n\n\n<p>Ce qui est rigolo avec ce concept de serverless, c’est que vous pouvez y mettre toute votre application web par exemple ou simplement quelques fonctions critiques. Et c’est cela dont on va parler aujourd’hui.</p>\n\n\n\n<p>En effet, je vais vous expliquer comme exécuter une simple fonction écrite en PHP dans le cloud Amazon, en utilisant leur serveur AWS Lambda.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221114-d9j.webp\" alt=\"\" class=\"wp-image-131403\" width=\"645\" height=\"173\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221114-d9j.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221114-d9j-300x81.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221114-d9j-768x206.webp 768w\" sizes=\"(max-width: 645px) 100vw, 645px\" /></figure></div>\n\n\n<p>Lambda permet d’exécuter du code pour n’importe quel type d’application ou service backend sans avoir à administrer un serveur et en payant uniquement le temps de calcul que vous utilisez. Quand le code n’est pas exécuté, vous n’êtes pas facturé.</p>\n\n\n\n<h2>De quoi a-t-on besoin ?</h2>\n\n\n\n<p>Vous allez avoir besoin d’un compte chez AWS pour accéder à <a href=\"https://aws.amazon.com/fr/lambda/?tag=amazon0d16-21\" target=\"_blank\" rel=\"noopener\">Lambda</a>. Nativement avec Lambda, vous pouvez créer des fonctions nodejs, python, go…etc. Mais pas PHP, en tout cas, pas avec les outils fournis au niveau de la console d’administration d’AWS Lambda</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221114-d9z.webp\" alt=\"\" class=\"wp-image-131404\" width=\"695\" height=\"225\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221114-d9z.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221114-d9z-300x97.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221114-d9z-768x249.webp 768w\" sizes=\"(max-width: 695px) 100vw, 695px\" /></figure></div>\n\n\n<p>Donc pour contourner le souci, on va utiliser un framework Composer qui s’appelle <a href=\"http://bref.sh/\" target=\"_blank\" rel=\"noopener\"><strong>Bref</strong></a> et qui permet de faire tourner du PHP en Serverless sans se prendre la tête. C’est top pour des jobs cron, des API ou des petits sites web dont les assets sont servis par Amazon S3.

Mais avec un petit fond sonore, c’est mieux !</p>\n\n\n\n<p>Mais on ne peut pas diffuser n’importe quelle musique sur Twitch car sinon, ces derniers coupent le son pour des questions de droits d’auteur.</p>\n\n\n\n<p>Je suis donc passé par le site Chillhop qui propose des morceaux Lo-Fi / Chill parfaits pour faire un fond sonore sympa dans mon stream. Pour intégrer leur musique, j’avais alors 2 possibilités : Streamer leur playlist via Spotify ou streamer leur live YouTube, directement depuis OBS.</p>\n\n\n\n<p>Spotify, je m’en sers pour écouter ma musique copyrightée toute la journée donc je ne pouvais pas le dédier à ça. J’ai donc créé une source browser chargeant une page HTML de mon cru permettant de jouer la playlist Chillhop en auto play.</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"lofi hip hop radio - beats to study/relax to 🐾\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/7NOSDKb0HlU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen></iframe>\n</div></figure>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-889942282\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>C’était cool et ça fonctionnait bien. Jusqu’au jour où Chillhop (ou YouTube) a bloqué l’autoplay sur ses Lives.</p>\n\n\n\n<p>Plus de musique de fond sur mes streams. J’étais tristesse. Puis au bout d’un moment, mes millions de viewers ont commencé à me réclamer de la musique en fond sonore.</p>\n\n\n\n<p>N’écoutant que mon abnégation à leur égard, j’ai donc décidé de trouver la parade pour streamer un live YouTube dans OBS. Je vais vous détailler tout ça, étape par étape. Pensez bien à envoyer l’URL de cet article à votre streamer ou streameuse préférée.</p>\n\n\n\n<p>Je suis donc parti (grâce aux conseils de ma communauté) sur l’option VLC qui permet de tout faire et surtout de lire une vidéo YouTube directement depuis le player comme ceci (je suis sous macOS, mais pour Windows ou Linux, c’est le même principe) :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>/Applications/VLC.app/Contents/MacOS/VLC <strong>'https://www.youtube.com/watch?v=7NOSDKb0HlU'</strong></code></pre>\n\n\n\n<p>Je sais, il y a une source VLC dans OBS, mais je n’ai jamais réussi à la faire fonctionner correctement. Donc je suis parti sur VLC, mais chargé à l’extérieur d’OBS.</p>\n\n\n\n<p>Sauf que je n’ai pas besoin de la vidéo, mais uniquement du son. J’ai donc rajouté ce paramètre :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>/Applications/VLC.app/Contents/MacOS/VLC 'https://www.youtube.com/watch?v=7NOSDKb0HlU' <strong>--no-video</strong></code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1656088500\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>À ce moment-là, le logiciel que j’utilise pour ma table de mixage (<a href=\"https://rogueamoeba.com/loopback/\" target=\"_blank\" rel=\"noopener\">Loopback</a>) n’est pas encore compatible avec la dernière version de macOS. Je ne pouvais donc pas récupérer le son provenant de VLC.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221020-d61.webp\" alt=\"\" class=\"wp-image-131001\" width=\"692\" height=\"255\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221020-d61.webp 1024w, https://korben.info/app/uploads/2022/10/SCR-20221020-d61-300x111.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221020-d61-768x284.webp 768w\" sizes=\"(max-width: 692px) 100vw, 692px\" /></figure></div>\n\n\n<p>Il fallait donc que je me débrouille sans ça.</p>\n\n\n\n<p>J’ai donc entrepris de créer toujours avec VLC, un streaming du live YouTube de Chillhop, qui serait accessible via l’URL http://localhost:2323 que je pourrais alors charger dans une source « Media Source » dans OBS.</p>\n\n\n\n<p>Ca donne donc ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>/Applications/VLC.app/Contents/MacOS/VLC 'https://www.youtube.com/watch?v=7NOSDKb0HlU' --no-video <strong>--sout '#standard{access=http,mux=ogg,dst=localhost:2323}'</strong></code></pre>\n\n\n\n<p>Impeccab’ comme dirait le chef Michel Dumas. Je peux alors créer ma nouvelle Media Source dans OBS et avoir le son de Chillhop.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"746\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221020-dfy.webp\" alt=\"\" class=\"wp-image-131002\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221020-dfy.webp 1024w, https://korben.info/app/uploads/2022/10/SCR-20221020-dfy-300x219.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221020-dfy-768x560.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Mais il y a deux problème à cette ligne de commande : </p>\n\n\n\n<ul><li>Il faut que je pense à la lancer avant de démarrer mon live.

C’est là que j’ai appris l’existence des scripts dans OBS. En effet, on peut coder des scripts pour interagir avec OBS, soit en Python, soit en LUA. Je suis fan de Python donc je me dis que ça va être vite torché, mais malheureusement, j’ai eu beau spécifier le bon interpréteur Python dans OBS, impossible de faire tourner le moindre script Python. Même un hello world ça ne fonctionnait pas.</p>\n\n\n\n<p>Je ne pouvais pas non plus y passer des heures, donc je me suis rabattu sur le LUA. J’ai donc pondu ce script en LUA pour appeler ma ligne de commande VLC. Vous allez voir, c’est plusieurs centaines de lignes de code ultra complexes. Non, je déconne, c’est juste une ligne de merde : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>-- Script LUA pour charger la musique de Chillhop dans OBS - https://korben.info\n\n<strong>os.execute(\"/Applications/VLC.app/Contents/MacOS/VLC -I http 'https://www.youtube.com/watch?v=7NOSDKb0HlU' --no-video --sout '#standard{access=http,mux=ogg,dst=localhost:2323}'\")</strong></code></pre>\n\n\n\n<p>J’ai sauvegardé ce script en le nommant chillhop.lua, puis je me suis rendu dans OBS, menu « Tools » > « Scripts » et j’ai simplement ajouté mon script Lua dedans :</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"730\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221020-dli.webp\" alt=\"\" class=\"wp-image-131004\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221020-dli.webp 1024w, https://korben.info/app/uploads/2022/10/SCR-20221020-dli-300x214.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221020-dli-768x548.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1293277903\"><div id='optidigital-adslot-Content_5' style='display:none;' class=\"Content_5\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos5' style='display:none;' class=\"Mobile_Pos5\"></div></div><p>J’ai relancé OBS et là, je me suis rendu compte que ça freezait tout mon OBS. En effet, en se chargeant, VLC bloque la suite du chargement de l’application. J’ai donc rajouté un petit & à la fin de la commande pour que OBS reprenne immédiatement la main et n’attende pas comme un con que VLC ait terminé.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>os.execute(\"/Applications/VLC.app/Contents/MacOS/VLC -I http 'https://www.youtube.com/watch?v=7NOSDKb0HlU' --no-video --sout '#standard{access=http,mux=ogg,dst=localhost:2323}' <strong>&</strong> \")</code></pre>\n\n\n\n<p>Et voilà, ça fonctionne. OBS démarre, exécute le script LUA qui à son tour lance VLC en arrière plan pour lire la musique et OBS peut alors récupérer dans sa Media Source le son diffusé via l’adresse localhost. C’est transparent et rapide.</p>\n\n\n\n<p>Ce qui est cool avec tout ça, c’est que ça ouvre un monde de possibilité pour augmenter et piloter OBS tout en script. C’est donc à creuser. Il ne me manque plus que les bonnes idées maintenant.</p>\n",

Mais si c’est le cas, c’est qu’il y a de nombreuses bonnes raisons de le faire. Régulièrement cités <strong>parmi les services VPN les plus fiables</strong>, ils sont aussi plutôt novateurs et proposent des options qui deviennent régulièrement des standards. L’une des dernières en date étant <strong>l’innovation Nexus</strong>.</p>\n\n\n\n<p>Exclusivité Surfshark, <strong>Nexus</strong> permet de connecter l’ensemble du parc de serveurs (+ de 3200) en un seul réseau qui couvre quasiment la planète entière. Le premier bénéfice étant de rendre votre <strong>connexion plus stable et rapide</strong>. Finis d’être connecté à un serveur unique dont les performances vont être dégradées s’il est surchargé. Par effet cascade le second avantage est donc d’améliorer votre confidentialité. Puisque les informations transitent via plusieurs serveurs, cela fragmente la surveillance possible et renforce donc votre protection. Cette nouveauté sera déployée totalement d’ici fin 2023.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"750\" height=\"418\" decoding=\"async\" src=\"https://me.korben.info/gds-surfshark4\" alt=\"Surfshark Nexus\"/></figure></div>\n\n\n<p>En attendant vous bénéficiez toujours des fonctionnalités déjà présentes :</p>\n\n\n\n<ul>\n<li>chiffrement de bout en bout (algo AES 256 GCM)</li>\n\n\n\n<li>utilisation de protocoles sécurisés (WireGuard, IKv2/IPsec …)</li>\n\n\n\n<li>mode camouflage (cache à votre FAI que vous utilisez un VPN)</li>\n\n\n\n<li>bouton kill switch (empêche vos données de fuiter lors d’une déconnexion sauvage)</li>\n\n\n\n<li>le split tunneling</li>\n\n\n\n<li>la protection lorsque vous vous connectez à un Wi-Fi public</li>\n\n\n\n<li>rotation d’IP (sans déconnexion)</li>\n\n\n\n<li>pas de conservations des logs</li>\n\n\n\n<li>blocage des pubs, cookies et autres malwares</li>\n\n\n\n<li></li>\n\n\n\n<li>etc.</li>\n</ul>\n\n\n\n<p>D’autres nouveautés sont encore prévues dans les prochains mois, parce qu’on peut toujours faire mieux. Comme par exemple la <strong>génération automatique d’une nouvelle adresse IP</strong> pour chaque site que vous visitez (sans devoir déconnecter/reconnecter l’outil). Si la <strong>fonction MultiHop</strong> est déjà disponible (elle permet de mettre un serveur supplémentaire entre vous et le site auquel vous vous connectez), elle disposera bientôt d’une option pour l’automatiser dans certains cas.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"250\" height=\"141\" decoding=\"async\" src=\"https://media.giphy.com/media/krM6ANSNvFg52/giphy.gif\" alt=\"\"/><figcaption class=\"wp-element-caption\">Exemple de MultiHop automatique</figcaption></figure></div>\n\n\n<p>Vous voulez tester le service pour pas cher ? Il est encore temps de <a href=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">profiter de l’offre Black Friday 2022</a> ! Cette dernière dure jusqu’au 27 novembre et vous permet de ne payer que 2.05 € par mois (en prenant l’abonnement 2 ans + 2 mois offert). Pour 26 mois cela ne vous reviendra même pas à 54€ au total, hors TVA, soit 84% de rabais. Ce qui fait toujours bien plaisir en pleine période d’inflation. Un prix quasi imbattable pour un VPN de ce calibre.</p>\n\n\n\n<p>Si vous êtes du genre à passer pas mal de commandes sur différents e-commerces, vous pourrez récupérer cette somme assez facilement. Comme vous le savez, les prix de certains produits, des billets d’avions ou de trains, d’un service de location … sont parfois dépendants de votre lieu de connexion. Avec Surfshark il suffit de tester depuis différents pays pour comparer les tarifs et prendre le plus intéressant pour vous. Et avec des serveurs dans plus de 100 localisations, il y a de quoi faire des tests et des comparaisons (sortez votre tableur Excel ;)).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"270\" decoding=\"async\" src=\"https://media.giphy.com/media/l1IY5NRhxdCJYxsmA/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Vous pouvez même partager le prix de l’abonnement avec plusieurs membres de la famille puisque le nombre d’appareils supportés est illimité ! Votre enfant n’a que 8 ans ? Pas d’excuses, il faut lui apprendre les dures réalités économiques. S’il veut continuer à regarder Adibou ou Pokémon, faut raquer ;p. Alors que d’autres solutions vont (parfois) jusqu’à 10 ou 12 appareils, Surfshark vous permet de protéger absolument tout et tout le monde. L’ordinateur fixe, les 2 laptops, les 4 téléphones portables, la console de salon, le routeur et les équipements de la maison (Smart TV & Co) … tout sera pris en charge.</p>\n\n\n\n<p>Et surtout, en plus d’être très abordable, Surfshark est un VPN parmi les plus fiables actuellement sur le marché. On ne compte plus les distinctions et prix qu’ils ont reçus ces 2 dernières années. Si vous n’êtes pas encore convaincu, profitez de l’<a href=\"https://surfshark.com/fr/download\" data-type=\"URL\" data-id=\"https://surfshark.com/fr/download\" target=\"_blank\" rel=\"noreferrer noopener\">essai gratuit de 7 jours</a> (sur Android, iOS et macOS).</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a rel=\"noreferrer noopener\" href=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768\" data-type=\"URL\" data-id=\"https://get.surfshark.net/aff_c?offer_id=87&aff_id=13768\" target=\"_blank\">Découvrir Surfshark VPN</a></h2>\n",

Surtout que <a href=\"https://grumpygamer.com/\" target=\"_blank\" rel=\"noopener\">Ron Gilbert</a>, le créateur de la série, revient 30 ans après son départ pour réaliser ce sixième épisode ! <a href=\"https://returntomonkeyisland.com/\" target=\"_blank\" rel=\"noopener\"><strong>Return to Monkey Island</strong></a> nous fait la promesse de répondre au cliffhanger laissé en suspend à la fin du deuxième opus, mais aussi de nous dévoiler le véritable secret de l’île aux singes. 🙈</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Return To Monkey Island – Retour chez les pirates !

Dispo dans le jeu <a href=\"https://returntomonkeyisland.com/the-story-so-far\" target=\"_blank\" rel=\"noopener\">mais aussi en ligne</a>, c’est mignon, rigolo, et bien pensé !</p>\n\n\n\n<p>Ce qui frappe en premier lieu, c’est l’univers graphique, très différent de ce qu’on a pu voir auparavant. Faut dire que chaque jeu propose un style artistique unique, et celui-ci ne fait pas exception à la règle. Mais lorsque le jeu fut annoncé et les premières images dévoilées, nombre de trolls se sont indignés (à tel point que Ron Gilbert a cessé toute communication). J’étais sceptique mais une fois dans le jeu, franchement, à part quelques points particuliers, c’est magnifique. Tout est très lisible, coloré, détaillé, super bien animé…</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-4-1024x576.webp\" alt=\"\" class=\"wp-image-131344\" srcset=\"https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-4-1024x576.webp 1024w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-4-300x169.webp 300w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-4-768x432.webp 768w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-4-1536x864.webp 1536w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-4.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Ajoutez à cela un habillage sonore enchanteur avec d’excellentes musiques, et on est embarqué direct dans l’ambiance ! On retrouve le thème principal de la série, évidemment, mais pas que. 😉 Les arrangements sont super réussis, j’ai adoré !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1488330414\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Enfin bref, on est là pour vivre une aventure de pirates et résoudre plein d’énigmes. Qu’en est-il de ce côté là ? Eh bien, je suis désolé pour le manque de suspense mais c’est encore une réussite. 🦜 L’interface est bien foutue, accessible et ergonomique. Il y a un mode « facile » pour les personnes qui ne connaissent pas trop ce genre de jeu, c’est une bonne idée mais attention, ça enlève certaines énigmes et donc certaines parties de l’histoire. Je conseille de jouer en mode « difficile ».</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-2-1024x576.webp\" alt=\"\" class=\"wp-image-131341\" srcset=\"https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-2-1024x576.webp 1024w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-2-300x169.webp 300w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-2-768x432.webp 768w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-2-1536x864.webp 1536w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-2.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>L’histoire est vraiment très bien écrite, c’est super drôle et prenant. Le rythme énigmes / dialogues / découverte de nouveaux lieux m’a semblé équilibré, avec toujours une certaine liberté dans l’ordre d’appréhender les choses. On est jamais totalement coincé devant un truc sans savoir quoi faire, on peut toujours aller voir ailleurs et avancer d’une manière ou d’une autre.</p>\n\n\n\n<p>Au pire, y a un système d’aide intégré au jeu, qui donne quelques indices sans jamais dévoiler la solution. Vraiment mieux que d’aller chercher la <em>soluce</em> sur le web, c’est bien dosé, vraiment nickel !</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-3-1024x576.webp\" alt=\"\" class=\"wp-image-131342\" srcset=\"https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-3-1024x576.webp 1024w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-3-300x169.webp 300w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-3-768x432.webp 768w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-3-1536x864.webp 1536w, https://korben.info/app/uploads/2022/11/Return-to-Monkey-Island-3.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>On sent l’attention porté à chaque détail, et ce, sur chaque aspect. Les nouveaux venus sont accueillis aux petits soins, et les vieux de la vieille apprécieront les multiples références faites aux anciens jeux. Je pense que chacun peut y trouver son compte.</p>\n\n\n\n<p>Non franchement j’ai été conquis de bout en bout, pour les plus radins le jeu est actuellement disponible sur le Xbox Gamepass, mais vous pourrez aussi le trouver sur <a href=\"https://store.steampowered.com/app/2060130/Return_to_Monkey_Island/\" target=\"_blank\" rel=\"noopener\">Steam</a> (compatible Windows, Mac et Linux), <a href=\"https://www.nintendo.com/store/products/return-to-monkey-island-switch/\" target=\"_blank\" rel=\"noopener\">Nintendo Switch</a>, <a href=\"https://store.playstation.com/fr-fr/concept/10006133/\" target=\"_blank\" rel=\"noopener\">Playstation 5</a>, <a href=\"https://www.xbox.com/fr-FR/games/store/return-to-monkey-island/9pc4r8n1n2t6\" target=\"_blank\" rel=\"noopener\">Xbox Series X/S</a>… Pour moins de 25€ je ne peux que vous le conseiller !</p>\n",

Ce n’est pas un plaisir pour eux, surtout qu’en général, le premier contact qu’on a avec quelqu’un, qui plus est par Internet, se fait via l’écrit.</p>\n\n\n\n<p>Et si le message est bourré de fautes, l’autre en face a vite fait de ranger celui qui lui écrit dans un tiroir mental étiqueté « teubé » ou assimilé alors que ce n’est pas forcément le cas.</p>\n\n\n\n<p>Sachez-le, quand vous faites des erreurs à l’écrit, vous vous démarquez négativement, et cela même si vous avez de bonnes raisons « techniques » de massacrer l’orthographe. C’est triste mais c’est comme ça.</p>\n\n\n\n<p>Du côté du lecteur, même si on peut être très tolérant sur les raisons qui poussent à commettre des fautes, c’est aussi très « douloureux ». Lire un texte plein de fautes, c’est buter sur chaque mot. L’expérience n’est pas agréable. Pire, quand on est censé lire un article rédigé par un journaliste, un professionnel, on se dit qu’on est vraiment tombé sur des amateurs. Pourtant, les coquilles existent, j’en sais quelque chose.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1303020776\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Alors que faire ? </p>\n\n\n\n<p>Plusieurs options : </p>\n\n\n\n<p>Soit on s’en fout et on espère qu’un jour, les gens arrêtent de juger négativement ceux qui font des erreurs dans leurs messages.</p>\n\n\n\n<p>Soit on se sort les doigts et on s’équipe. D’abord de connaissances en orthographe et en grammaire. <a href=\"https://www.google.com/search?client=safari&rls=en&q=regles+basiques+d%27orthographe+et+grammaire&ie=UTF-8&oe=UTF-8\" target=\"_blank\" rel=\"noopener\">Les règles sont simples, il suffit de rebosser un peu le sujet</a>. Une fois adulte, on trouve ça beaucoup plus sympa. Et surtout, on trouve un bon correcteur orthographique.</p>\n\n\n\n<p>Par exemple, je ne jure que par <a href=\"https://korben.info/test-antidote.html\">Antidote dont je vous ai déjà parlé ici</a>. Mais il en existe d’autres gratuits, certes limités dans leur version de base mais indispensable pour mettre un petit coup de lustrage sur vos textes.</p>\n\n\n\n<p>Je pense bien sûr à <a href=\"https://bonpatron.com/fr/\" target=\"_blank\" rel=\"noopener\">BonPatron</a> qui est le boss du game depuis 1795, et plus récemment le service <a href=\"https://www.merci-app.com/\" target=\"_blank\" rel=\"noopener\"><strong>Merci-app</strong></a> qui se présente sous la forme d’une extension pour Chrome, Firefox et Edge et qui permet d’un seul clic de contrôler l’orthographe et la grammaire de base de tous vos messages.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-183755026\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Ce n’est pas grand-chose en apparence mais ce sera suffisant pour à la fois envoyer des messages corrects et surtout apprendre de vos erreurs. L’outil est également capable de contrôler la cohérence de vos espacements et d’obtenir des stats sur vos écrits.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221019-lok.webp\" alt=\"\" class=\"wp-image-130983\" width=\"664\" height=\"439\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221019-lok.webp 1024w, https://korben.info/app/uploads/2022/10/SCR-20221019-lok-300x199.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221019-lok-768x509.webp 768w\" sizes=\"(max-width: 664px) 100vw, 664px\" /></figure></div>\n\n\n<p>Si cela vous tente, vous pouvez bien sûr tester l’outil directement sur son site, avant d’installer l’extension. Vous pouvez ainsi contrôler jusqu’à 5000 caractères.</p>\n\n\n\n<p>En tout cas, depuis que j’utilise ce genre d’outils, je fais beaucoup moins de fautes, et surtout je gagne un temps de dingue en relecture.</p>\n\n\n\n<p>Pensez-y !</p>\n",

Si vous utilisez déjà Surfshark pour surfer, vous n’aurez rien de plus à installer pour profiter de l’antivirus. Celui-ci est intégré au logiciel et ça permet d’alléger votre machine en ayant un seul outil qui fait tout.</p>\n\n\n\n<p><strong>Notez que pour le Black Friday, vous pouvez profiter d’un an d’Antivirus + du VPN Surfshark (et ses services associés Alert et Search) pour seulement 2,32 $ par mois avec 2 mois offerts soit un abonnement à l’année ramené à 28,70 $, ce qui fait environ 27,7 euros.</strong></p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/11/1200x628-44.webp\" alt=\"\" class=\"wp-image-131376\" width=\"628\" height=\"328\" srcset=\"https://korben.info/app/uploads/2022/11/1200x628-44.webp 1024w, https://korben.info/app/uploads/2022/11/1200x628-44-300x157.webp 300w, https://korben.info/app/uploads/2022/11/1200x628-44-768x402.webp 768w\" sizes=\"(max-width: 628px) 100vw, 628px\" /></a></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"817\" height=\"597\" decoding=\"async\" src=\"https://me.korben.info/l4w-surfshark-antivirus\" alt=\"\"/></figure></div>\n\n\n<p>Disponible sous Windows, macOS et Android, <a rel=\"noopener\" href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\">l’antivirus Surfshark est vraiment très facile à utiliser</a>. Comme vous pouvez le voir sur les captures écran, l’interface est plutôt limpide et épurée à destination des débutants et des gens qui ne veulent plus se prendre la tête avec un antivirus lourdingue. Au contraire, Surfshark a mis un point d’honneur à rendre son antivirus très léger aussi bien pour votre RAM que pour votre processeur même lors des scans approfondis.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"817\" height=\"597\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2.webp\" alt=\"\" class=\"wp-image-130679\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2.webp 817w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2-300x219.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2-768x561.webp 768w\" sizes=\"(max-width: 817px) 100vw, 817px\" /></figure></div>\n\n\n<p>Au niveau des fonctionnalités, l’antivirus propose tout le nécessaire que nous sommes en droit d’attendre d’un antivirus. Tout d’abord, il est possible de lancer des analyses manuelles de vos disques dès que vous en ressentez le besoin. Mais le mieux c’est encore de programmer tout cela, avec des analyses régulières (par exemple 1 fois par semaine), ce qui permet de tout simplement l’oublier tout en restant protégé.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"817\" height=\"597\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5j.webp\" alt=\"\" class=\"wp-image-130680\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5j.webp 817w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5j-300x219.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5j-768x561.webp 768w\" sizes=\"(max-width: 817px) 100vw, 817px\" /></figure></div>\n\n\n<p>Évidemment, il sécurise et surveille votre ordinateur avec une surveillance en temps réel, là où d’autres antivirus (gratuits la plupart du temps) se contentent d’un scan passif.</p>\n\n\n\n<p>Et si vous téléchargez un fichier sur lequel vous avez un doute, vous pouvez également le glisser-déposer sur l’outil pour que celui-ci analyse son contenu.</p>\n\n\n\n<p>Concernant le moteur de l’antivirus, ce dernier repose sur le célèbre Avira et peut prévenir les attaques de type Zéro Day (exploitant des failles nouvelles non corrigées) grâce au système <a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\" rel=\"noopener\">Surfshark Cloud Protect</a> qui mutualise toutes les détections de virus à l’échelle de tous leurs clients.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"817\" height=\"597\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2.webp\" alt=\"\" class=\"wp-image-130681\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2.webp 817w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2-300x219.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2-768x561.webp 768w\" sizes=\"(max-width: 817px) 100vw, 817px\" /></figure></div>\n\n\n<p>Alors bien sûr, c’est un antivirus encore jeune, mais solide puisqu’il repose sur un moteur déjà bien éprouvé. De plus, Surfshark est connu pour fournir un service de qualité, que ce soit pour son VPN ou les autres produits de la gamme Surfshark One.</p>\n\n\n\n<p>L’avantage avec l’antivirus Surfshark, c’est que si vous utilisez déjà leur VPN, vous n’aurez rien à installer de plus (il faut juste prendre l’abonnement Surfshark One). Et si vous hésitiez à choisir un VPN ou un Antivirus, grâce à l’offre de Surfshark, vous pourrez combiner les deux sans alourdir votre machine.</p>\n\n\n\n<p><a rel=\"noopener\" href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\">Je vous invite à en découvrir plus en cliquant ici.</a></p>\n",

C’est l’heure de vous donner quelques nouvelles même si je sais que ces éditos sont beaucoup moins lus que tous les merveilleux articles que je vous propose chaque jour.</p>\n\n\n\n<p>Ici dans mon QG auvergnat, tout se passe bien. Les travaux dans la maison avancent doucement, mais surement et au niveau de l’extérieur, je peaufine <a href=\"https://www.instagram.com/p/CkQsGSzI4h9/\" target=\"_blank\" rel=\"noopener\">ma maitrise de la tronçonneuse</a> (j’aime d’amour ma tronçonneuse) et mes <a href=\"https://www.instagram.com/p/Cjf_FEYuL9V/\" target=\"_blank\" rel=\"noopener\">connaissances mycologiques</a>. Je vous rassure tout de suite, <a href=\"https://www.instagram.com/p/CkYKnv0IXkc/\" target=\"_blank\" rel=\"noopener\">j’ai tous les EPI</a> (équipements de protection) et en cas de doute sur un champi, je ne tente pas 🙂</p>\n\n\n\n<p>Le mois dernier, j’ai fait de la confiture de coings que j’ai baptisée « <a href=\"https://www.instagram.com/p/Cj4p-Ozo3-i/\" target=\"_blank\" rel=\"noopener\">LeBonCoing</a> » et j’en ai même envoyé 2 pots à LeBonCoin, ce qui les a fait marrer :). Et ce mois-ci ma mission, <a href=\"https://www.instagram.com/p/CkltClCIfId/\" target=\"_blank\" rel=\"noopener\">c’est préparation des olives du jardin pour l’apéro</a>. Je l’ai déjà fait y’a deux ans et c’était trop bon, alors je remets le couvert cette année, mais avec encore plus d’olives. Il a été super productif le pépère.</p>\n\n\n\n<p>Voilà, évidemment, c’est pas très tech tout ça, mais la tech, j’en parle déjà chaque jour. Les éditos sont faits pour ça 😉</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-522601528\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>J’ai bien sûr repris les <a href=\"http://twitch.tv/korbenfr\" target=\"_blank\" rel=\"noopener\">Twitch les lundi, mardi et jeudi après-midi</a> et je dois dire qu’on rigole bien. Comme d’hab, je papote avec les followers, j’écris mes articles et je bidouille des trucs. Après si vous n’êtes pas dispo à ces heures là, y’a évidemment les replays. Côté TikTok, ça commence a devenir également sérieux puisque j’ai atteint <a href=\"https://www.tiktok.com/@korbeninfo\" target=\"_blank\" rel=\"noopener\">un nombre conséquent d’abonnés</a>. Ça ne rigole plus 🙂</p>\n\n\n\n<p>D’ailleurs demain même si c’est férié, ça va être tournage de vidéos. C’est amusant à faire, donc c’est que du plaisir, je vous rassure 🙂</p>\n\n\n\n<p>Voilà pour les news. L’hiver est enfin là, donc le mood est au feu de cheminée, au chocolat chaud et bientôt à la raclette ^^. Noël arrive, faut bien commencer à se mettre dans l’ambiance.</p>\n\n\n\n<p>Bon et vous ça va ?</p>\n\n\n\n<p>Tchuss !</p>\n",

Mais est-ce la seule chose que vous pouvez faire ? Bien sûr que non. Et aujourd’hui je vais vous proposer <strong>quelques actions quotidiennes</strong> que vous pouvez mettre en place pour vous protéger sur le long terme.</p>\n\n\n\n<p>Avant de commencer, j’insiste juste sur le fait que chaque jour lorsque vous surfez sur le web, que vous utilisez des applications, etc. vos données sont récupérées. C’est comme ça. Et même par des services fiables cela peut créer des problèmes. Ils peuvent se faire hacker leur base de données, des employés peuvent les revendre en soum soum ou la société peut décider de faire un rab de moula en la revendant une fois qu’elle a fermé ses portes. Bref tout atterrit <strong><a href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768&source=inc\" target=\"_blank\" rel=\"noopener\">chez des data brokers qui collectent toutes ces infos</a></strong> et les revendent à prix d’or. Parfois ces data brokers rachètent même des sites en perdition, juste pour disposer de la collecte de données qui a été réalisée (à des fins légitimes) pendant des années.</p>\n\n\n\n<p>Et même sans ça, vos données personnelles se retrouvent parfois disponibles en toute connaissance de cause. Par exemple sur des sites de fiches d’entreprise lorsque vous créez une société, ou dans les fichiers PDF d’un listing de diplômés d’une école, de chercheurs dans une étude, etc.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"317\" decoding=\"async\" src=\"https://media.giphy.com/media/h55EUEsTG9224/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Bref nous sommes <strong>tous et toutes les vaches à lait de cette industrie</strong>. De manière directe ou au moins via les personnalités que nous nous créons en ligne (qui finissent par nous ressembler au final). Et s’il est difficile de supprimer à 100% toutes nos traces numériques (surtout que la plupart du temps nous ne sommes même pas conscients d’où elles circulent), il existe quelques possibilités pour limiter notre exposition.</p>\n\n\n\n<h3>1) Ne créez pas de compte si ce n’est pas nécessaire</h3>\n\n\n\n<p>Bon je sais, vous allez me dire que c’est obvious. Je sais que ce n’est pas votre cas, mes lecteurs adorés ont un QI supérieur à la moyenne. Mais qui ne connait pas une personne qui s’ouvre un compte sur un e-commerce quelconque pour commander un objet pas cher et va ensuite laisser son compte existant pendant des années ? Peut-être qu’en se demandant au départ si l’objet en question est vraiment utile, le compte n’aurait jamais eu besoin d’être créé.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"358\" decoding=\"async\" src=\"https://media.giphy.com/media/xUPOqmCwBBEVPBOFYQ/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Est-ce qu’ouvrir un 4e compte Instagram pour publier uniquement les photos de la tortue de compagnie est vraiment utile ? À vous de voir. Et si c’est le cas, passez au point suivant lorsqu’il ne vous est plus d’aucune utilité. </p>\n\n\n\n<p>Dans le même esprit, ne donnez pas votre téléphone sans raison. Aussi bien dans les applis mobiles que dans les magasins physiques (si on vous les demande parfois ce n’est que dans un seul but : vous balancer de la pub).</p>\n\n\n\n<h3>2) Fermer et supprimer vos comptes inutilisés</h3>\n\n\n\n<p>Je sais que vous avez déjà pensé à ce point. Mais êtes-vous vraiment un bon élève ? Vous êtes certain qu’il n’y a pas un petit compte non utilisé depuis 2 ans et que vous gardez parce que la flemme de retrouver le mot de passe ? Ou parce qu’on ne sait jamais, vous pourriez en avoir besoin un jour ?</p>\n\n\n\n<p>La question de la vie privée était beaucoup moins présente il y a 10 ans. Combien ont toujours des infos (ne serait-ce que l’email) sur des sites abandonnés comme MySpace, Flickr, StumbleUpon ou que sais-je ? À partir du moment où votre adresse mail est quelque part, elle pourra servir à des gens pour vous bombarder de spams (selon les estimations 97% des adresses mail en reçoivent). Pire, imaginez qu’il y a 10 ans vous aviez un Skyblog avec une photo gênante et que l’on parvienne à recouper l’info avec votre adresse mail toujours active aujourd’hui ?</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"270\" decoding=\"async\" src=\"https://media.giphy.com/media/l3q2Kgm3KOBUE6wF2/giphy-downsized-large.gif\" alt=\"\"/></figure></div>\n\n\n<p>C’est parfois bien caché dans les options, il faut parfois envoyer un mail personnalisé, etc., mais prenez le temps de le faire. Vous pouvez vous aider d’un site comme <a href=\"https://backgroundchecks.org/justdeleteme/fr.html\" data-type=\"URL\" data-id=\"https://backgroundchecks.org/justdeleteme/fr.html\" target=\"_blank\" rel=\"noreferrer noopener\">Just Delete Me</a>. </p>\n\n\n\n<p>Combien recevez-vous de communications commerciales que vous ne lisez jamais ? Est-ce que toutes les newsletters que vous recevez sont vraiment importantes ? Etc. Je suis sûr qu’il y a moyen de limiter ça.</p>\n\n\n\n<h3>3) Renforcez la vie privée sur les réseaux sociaux</h3>\n\n\n\n<p>Là encore ça semble logique, mais beaucoup ne prennent pas le temps d’effectuer les quelques clics nécessaires. Surtout que les réseaux sont sans doute LA source de récolte numéro 1 à l’heure actuelle. Lorsque vous partagez votre localisation, balancez une photo d’un endroit que vous visitez, parlez sans arrêt avec une même personne, etc. il n’est pas très compliqué pour les algorithmes de vite se faire une image assez précise de vous, de vos préférences et de qui sont vos proches.</p>\n\n\n\n<p>Et c’est d’autant plus le cas lorsque vous connectez les services entre-eux (en vous connectant à des sites tiers avec vos identifiants Google ou Facebook par exemple), là ce sont tous les services interconnectés qui peuvent accéder à vos données. Les réseaux sociaux tirent littéralement leurs bénéfices des publicités ciblées. Et pour en tirer le meilleur afin que leurs pubs soient les plus rentables possibles ? Il leur faut accéder au max de vos infos, bingo. Donc les paramètres de protections par défaut sont (trop) souvent permissifs.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"270\" decoding=\"async\" src=\"https://media.giphy.com/media/KPEpqHiJVrSVCOjyCP/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>À vous de limiter tout ça : ne pas laisser votre profil visible publiquement, retirer la géolocalisation, limiter qui a le droit de voir quoi, ne pas accepter la publicité ciblée, refuser les contenus supplémentaires, faire attention lorsque vous prenez des gens ou des lieux en photo, ne pas interconnecter les services, limiter au maximum les extensions, etc. Il y a quelques semaines je vous ai fait un petit guide pour <a href=\"https://korben.info/comment-disparaitre-de-google.html\" data-type=\"URL\" data-id=\"https://korben.info/comment-disparaitre-de-google.html\">disparaitre de Google</a>, ça pourrait vous servir. </p>\n\n\n\n<p>Ce n’est pas non plus une mauvaise idée de supprimer vos anciens posts/tweets/photos, etc. s’ils n’ont plus rien à faire dans votre profil.</p>\n\n\n\n<h3>4) Utilisez un navigateur web respectueux</h3>\n\n\n\n<p>Désinstallez Google Chrome, Microsoft Edge, Apple Safari & Co. Privilégiez Brave, Firefox ou Tor Browser qui sont les 3 navigateurs les plus sécurisés à ce niveau. Laissez-les faire le plus gros du travail de prévention, ils bloquent par défaut de nombreux traqueurs, les profils comportementaux, etc. Pour Tor il faut quand même mentionner que certains FAI (si pas tous) vont vous brider le débit dès qu’ils se rendront compte que vous l’utilisez. Mais, quel que soit celui que vous choisissez, continuer à limiter le nombre d’extensions installées.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"480\" height=\"324\" decoding=\"async\" src=\"https://media.giphy.com/media/YsZBbMUeDLFNjQTtjz/giphy.gif\" alt=\"\"/></figure></div>\n\n\n<p>Et si vous voulez voir ce qui transparait avec votre navigateur actuel, il existe des sites <a href=\"https://coveryourtracks.eff.org/\" data-type=\"URL\" data-id=\"https://coveryourtracks.eff.org/\" target=\"_blank\" rel=\"noreferrer noopener\">comme celui-ci</a>. Après sachez que même avec un bon navigateur, même avec un VPN, même avec Tor, etc. vous laisserez des bouts de traces.</p>\n\n\n\n<h3>5) Retrouvez et faites supprimer vos infos chez les data brokers</h3>\n\n\n\n<p>Maintenant que vous avez limité au mieux la future récolte de vos données, comment faire pour celles qui trainent déjà sur la toile ? Il faudrait pouvoir retrouver tous les data brokers qui disposent de ces données, cela éviterait qu’ils puissent continuer à les revendre. Si certains sont très connus (Spokeo, WhitePages …) pour d’autres, il est très compliqué de remonter jusqu’à eux. Si vous recevez un email de scam, un coup de fil marketing, etc. comment savoir d’où ces gens ont obtenu vos infos ? Et lorsque vous avez fait ce travail digne de l’inspecteur Derrick il faut encore obtenir du data broker qu’il supprime ce qui doit l’être. Multipliez cela par des dizaines de brokers et vous pouvez faire une croix sur vos soirées pour les 3 prochains mois.</p>\n\n\n\n<p>C’est là qu’intervient un service <a rel=\"noreferrer noopener\" href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768&source=inc\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768&source=inc\" target=\"_blank\">comme Incogni</a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"750\" height=\"422\" decoding=\"async\" src=\"https://me.korben.info/9u2-incogni1\" alt=\"\"/></figure></div>\n\n\n<p>Il vont faire le gros du travail pour vous. Déjà en répertoriant chez quels data brokers vos données personnelles se retrouvent, ensuite en les contactant à votre place pour qu’ils suppriment ces données et ensuite en faisant un suivit pour s’assurer qu’elles ne réapparaissent pas dans les prochaines années. Et si les brokers ne répondent pas aux demandes, Incogni va les relancer jusqu’à ce que ce soit fait. Qu’ils soient contactés par un service dont c’est la spécialité ou par le mail dindon63@gmail.com de Mr Machin , ça risque de faire une différence 😉</p>\n\n\n\n<p>Si vous avez pas mal bourlingué sur le web depuis de nombreuses années et avec une identité figée (même adresse mail, même numéro de téléphone, mêmes services utilisés …), votre profil doit être assez précis et répandu. Pour moins de 6€/mois, la solution Incogni fera le nécessaire et vous tiendra au courant étape par étape via son tableau de bord. J’ai d’ailleurs <a href=\"https://korben.info/incogni-test.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-test.html\">testé Incogni en détail</a> pour vous montrer comment cela se passe.</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img width=\"800\" height=\"414\" decoding=\"async\" src=\"https://korben.info/app/uploads/2022/09/incogni-tableau-de-bord.jpg\" alt=\"\"/></figure>\n\n\n\n<p>Pour résumer un peu tout ça, il faut avoir une bonne hygiène numérique au quotidien. Et lorsque les choses ont pris une certaine ampleur (ou que l’on prend seulement conscience de l’importance de faire respecter sa vie privée) il y a des services comme Incogni pour nous épauler. Bref nous ne sommes pas sans ressources.</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a rel=\"noreferrer noopener\" href=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768&source=inc\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&aff_id=13768&source=inc\" target=\"_blank\">Découvrez Incogni !</a></h2>\n",

Pour cela, lancez la commande « aimg » et entrez ceci :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>describe CHEMIN-VERS-IMAGE.jpg</code></pre>\n\n\n\n<p>Et comme c’est du Python, vous pouvez également l’appeler comme lib dans vos scripts.</p>\n\n\n\n<p>Bref, on est bien sûr loin de la qualité d’un Midjourney, mais avec beaucoup de temps et les bons mots clés, vous arriverez quand même à faire des choses correctes. Et le fait de pouvoir intégrer ça dans vos scripts peut vous permettre d’ajouter certaines fonctions sympas relatives à la compréhension / taggage d’une image ou tout simplement à la génération d’avatars ou d’images diverses.</p>\n\n\n\n<p><a href=\"https://github.com/brycedrennan/imaginAIry\" target=\"_blank\" rel=\"noopener\">À découvrir ici.</a></p>\n",

Déjà, y’a pas de client pour Linux. Mais surtout, on ne peut pas sauvegarder sur Backblaze tout ce qui est disque « réseaux ». Donc si vous avez un NAS par exemple, et bien vous ne pourrez pas le stocker chez eux.</p>\n\n\n\n<p>À moins de prendre leur abonnement B2 qui offre un stockage pur et dur sans logiciel client. Et des outils de backups qu’on trouve un peu partout, intégrant le plus souvent B2, au côté d’autres trucs comme Amazon S3, ou Azure Backup.</p>\n\n\n\n<p>Sauf que si vous payez déjà le <a href=\"https://secure.backblaze.com/r/00wmi7\" target=\"_blank\" rel=\"noopener\">Personal Backup de Backblaze</a>, c’est un peu relou de devoir tout refaire sur B2. Surtout que là, on sort un peu de l’offre intéressante puisque vous devrez payer ce que vous consommez.</p>\n\n\n\n<p>Alors, comment faire ? </p>\n\n\n\n<ul><li>Option 1, vous décidez d’adopter une mentalité One Life et abandonnez toute notion de sauvegarde.</li><li>Option 2, vous décidez de passer à la caisse parce que vous êtes blindé de thune et que vous avez du temps</li><li>Option 3, vous trichez et vous vous arrangez pour sauvegarder vos disques réseau sur Backblaze avec l’option « Personal Backup ».</li></ul>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-403108731\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Mais avant, un petit rappel du principe des sauvegardes 3-2-1. Le concept est simple : pour avoir des sauvegardes efficaces et sérieuses, vous devez réaliser : </p>\n\n\n\n<p>3 sauvegardes. 2 de ces sauvegardes sont stockées sur des supports différents (par exemple, un disque externe + un NAS) et la 3e sauvegarde doit être conservée hors site (donc pas chez vous). Cela peut être sur le cloud ou chez Tata Claude.</p>\n\n\n\n<p>L’idée c’est que si un incendie se déclare chez vous parce que vous avez chauffé votre maison avec vos meubles à cause de Bruno Lemaire, et bien même si toute votre famille a brulé, au moins, vous avez un backup de vos épisodes de Naruto.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/3-2-1-Backup-Rule.webp\" alt=\"\" class=\"wp-image-130921\" width=\"494\" height=\"200\" srcset=\"https://korben.info/app/uploads/2022/10/3-2-1-Backup-Rule.webp 1024w, https://korben.info/app/uploads/2022/10/3-2-1-Backup-Rule-300x122.webp 300w, https://korben.info/app/uploads/2022/10/3-2-1-Backup-Rule-768x312.webp 768w\" sizes=\"(max-width: 494px) 100vw, 494px\" /></figure></div>\n\n\n<p>Évidemment pour gagner du temps, vous pouvez faire partir les 2 premiers backups (locaux) depuis votre ordinateur et le dernier off-site depuis votre NAS.</p>\n\n\n\n<p>Ensuite pour revenir à Backblaze en cas de souci, vous pourrez alors récupérer vos données soit en les téléchargeant directement depuis leur site, soit en vous faisant livrer un disque dur contenant vos données.</p>\n\n\n\n<p>Alors, maintenant comment faire pour sauvegarder TOUT votre NAS vers Backblaze alors que les disques réseau ne sont pas supportés dans leur application cliente ?</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1681548937\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Et bien c’est simple, il faut gruger un peu et faire croire à l’outil que les répertoires réseau que vous voulez envoyer là-bas sont des répertoires locaux. Et pour cela, 2 façons de faire en fonction de votre OS.</p>\n\n\n\n<p>Si vous êtes sous Windows, il vous faudra utiliser le logiciel libre <a href=\"http://dokan-dev.github.io/\" target=\"_blank\" rel=\"noopener\">Dokany</a> qui permet de monter des systèmes de fichiers divers et variés (disque externe, disque réseau…etc.) pour les intégrer dans votre système de fichier actuel afin que toutes vos applications Windows puissent y accéder en toute transparence. Ainsi le client Backblaze verra ces fichiers comme s’ils étaient locaux et procédera à la sauvegarde. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"796\" height=\"448\" src=\"https://korben.info/app/uploads/2022/10/687474703a2f2f646f6b616e2d6465762e6769746875622e696f2f696d616765732f73637265656e636173742e676966.gif\" alt=\"\" class=\"wp-image-130922\"/></figure></div>\n\n\n<p>Vous pouvez bien sûr avoir d’autres cas d’usage pour cet outil.</p>\n\n\n\n<p>Et sous macOS, c’est le même concept sauf que ce n’est pas le même outil. Et celui-ci est payant, car les gens qui utilisent des logiciels Apple ont de la grosse moula évidemment.</p>\n\n\n\n<p>Il vous faudra donc vous offrir le logiciel <a href=\"https://automounter.app/\" target=\"_blank\" rel=\"noopener\">AutoMounter</a> pour la modique somme de 17 $ afin de monter vos disques distants un peu n’importe où sur votre système macOS.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221013-kkg.webp\" alt=\"\" class=\"wp-image-130923\" width=\"382\" height=\"449\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221013-kkg.webp 653w, https://korben.info/app/uploads/2022/10/SCR-20221013-kkg-255x300.webp 255w\" sizes=\"(max-width: 382px) 100vw, 382px\" /></figure></div>\n\n\n<p>Et voilà, ce n’est pas plus compliqué que ça. Et évidemment, les sauvegardes se feront de manière fluide, avec le client Windows ou MacOS <a href=\"https://secure.backblaze.com/r/00wmi7\" target=\"_blank\" rel=\"noopener\">Backblaze</a> dans le cadre de votre forfait Personal Backup.</p>\n",

Mais voici quand même un exemple. Imaginons que dans votre dossier Downloads, vous ayez des tas de PDF que vous voulez déplacer dans un sous-dossier PDF ?</p>\n\n\n\n<p>Lancez l’édition de la config d’Organize et scriptez comme ceci :</p>\n\n\n\n<pre class=\"wp-block-code\"><code># organize configuration file\n# https://organize.readthedocs.io\nrules:\n - name: \"Find PDFs\"\n locations:\n - ~/Downloads\n subfolders: true\n filters:\n - extension: pdf\n actions:\n - echo: \"Found PDF!\"\n - move: ~/Downloads/PDFs/\n</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221012-ct7.webp\" alt=\"\" class=\"wp-image-130867\" width=\"750\" height=\"702\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221012-ct7.webp 821w, https://korben.info/app/uploads/2022/10/SCR-20221012-ct7-300x281.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221012-ct7-768x718.webp 768w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></figure></div>\n\n\n<p>Comme vous pouvez le voir, une règle se compose : </p>\n\n\n\n<ul><li>D’un nom (name) (Vous mettre ce que vous voulez)</li><li>D’un ou plusieurs emplacements (locations)</li><li>D’actions (actions) pour afficher des messages ou agir sur les fichiers</li><li>Et d’un tas d’autres paramètres comme le parcours des sous dossiers, le filtrage des fichiers par extension…etc.</li></ul>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1876307667\"><div id='optidigital-adslot-Content_3' style='display:none;' class=\"Content_3\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos3' style='display:none;' class=\"Mobile_Pos3\"></div></div><p>Cet exemple n’est pas exhaustif. Il est par exemple possible de désactiver une règle en passant à « false » le paramètre « enabled ». Les filtres sont également intéressant car ils permettent de débusquer les fichiers selon la structure de leur nom.</p>\n\n\n\n<p>Il y a vraiment beaucoup de paramètres qui peuvent entrer en jeu dans chacune de vos règles donc je vous invite encore une fois à vous pencher sur la doc. Si par malheur, Organize rencontre des conflits de fichiers, l’outil dispose également d’options pour résoudre cela.</p>\n\n\n\n<p>Les données Exif peuvent également être extraites des fichiers pour ensuite être utilisées à votre convenance et l’outil est capable d’extraire du contenu de PDFs ou de fichiers DOCX…etc our mieux les catégoriser. C’est hyper puissant.</p>\n\n\n\n<p>Un mode « simulation » permet également de tester vos règles sans risque afin d’éviter de massacrer vos fichiers en cas d’erreur.</p>\n\n\n\n<p>Bref, un outil formidable qui en fait beaucoup. L’essayer c’est l’adopter !</p>\n",

Un moteur de recherche (<em>Surfshark Search</em>) qui vous permet d’obtenir des résultats non traqués et impartiaux (pas des résultats faussés par votre historique et vos recherches précédentes). Un système de surveillance (<em>Surfshark Alerts</em>) qui permet d’être alerté si certaines de vos informations personnelles sont divulguées.

Si vous utilisez déjà Surfshark pour surfer, vous n’aurez rien de plus à installer pour profiter de l’antivirus. Celui-ci est intégré au logiciel et ça permet d’alléger votre machine en ayant un seul outil qui fait tout.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"817\" height=\"597\" src=\"https://me.korben.info/l4w-surfshark-antivirus\" alt=\"\"/></figure></div>\n\n\n<p>Disponible sous Windows, macOS et Android, <a rel=\"noopener\" href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\">l’antivirus Surfshark est vraiment très facile à utiliser</a>. Comme vous pouvez le voir sur les captures écran, l’interface est plutôt limpide et épurée à destination des débutants et des gens qui ne veulent plus se prendre la tête avec un antivirus lourdingue. Au contraire, Surfshark a mis un point d’honneur à rendre son antivirus très léger aussi bien pour votre RAM que pour votre processeur même lors des scans approfondis.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"817\" height=\"597\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2.webp\" alt=\"\" class=\"wp-image-130679\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2.webp 817w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2-300x219.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5t-2-768x561.webp 768w\" sizes=\"(max-width: 817px) 100vw, 817px\" /></figure></div>\n\n\n<p>Au niveau des fonctionnalités, l’antivirus propose tout le nécessaire que nous sommes en droit d’attendre d’un antivirus. Tout d’abord, il est possible de lancer des analyses manuelles de vos disques dès que vous en ressentez le besoin. Mais le mieux c’est encore de programmer tout cela, avec des analyses régulières (par exemple 1 fois par semaine), ce qui permet de tout simplement l’oublier tout en restant protégé.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"817\" height=\"597\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5j.webp\" alt=\"\" class=\"wp-image-130680\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5j.webp 817w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5j-300x219.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5j-768x561.webp 768w\" sizes=\"(max-width: 817px) 100vw, 817px\" /></figure></div>\n\n\n<p>Évidemment, il sécurise et surveille votre ordinateur avec une surveillance en temps réel, là où d’autres antivirus (gratuits la plupart du temps) se contentent d’un scan passif.</p>\n\n\n\n<p>Et si vous téléchargez un fichier sur lequel vous avez un doute, vous pouvez également le glisser-déposer sur l’outil pour que celui-ci analyse son contenu.</p>\n\n\n\n<p>Concernant le moteur de l’antivirus, ce dernier repose sur le célèbre Avira et peut prévenir les attaques de type Zéro Day (exploitant des failles nouvelles non corrigées) grâce au système <a href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\" rel=\"noopener\">Surfshark Cloud Protect</a> qui mutualise toutes les détections de virus à l’échelle de tous leurs clients.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"817\" height=\"597\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2.webp\" alt=\"\" class=\"wp-image-130681\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2.webp 817w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2-300x219.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221005-l5z-2-768x561.webp 768w\" sizes=\"(max-width: 817px) 100vw, 817px\" /></figure></div>\n\n\n<p>Alors bien sûr, c’est un antivirus encore jeune, mais solide puisqu’il repose sur un moteur déjà bien éprouvé. De plus, Surfshark est connu pour fournir un service de qualité, que ce soit pour son VPN ou les autres produits de la gamme Surfshark One.</p>\n\n\n\n<p>L’avantage avec l’antivirus Surfshark, c’est que si vous utilisez déjà leur VPN, vous n’aurez rien à installer de plus (il faut juste prendre l’abonnement Surfshark One). Et si vous hésitiez à choisir un VPN ou un Antivirus, grâce à l’offre de Surfshark, vous pourrez combiner les deux sans alourdir votre machine.</p>\n\n\n\n<p><a rel=\"noopener\" href=\"https://get.surfshark.net/aff_c?offer_id=1066&aff_id=13768&source=fixed-av1\" target=\"_blank\">Je vous invite à en découvrir plus en cliquant ici.</a></p>\n",

Seulement voilà, Instagram c’est Facebook et Facebook c’est comme Satan pour baby-boomers.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-892986696\"><div id='optidigital-adslot-Content_1' style='display:none;' class=\"Content_1\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos1' style='display:none;' class=\"Mobile_Pos1\"></div></div><p>Alors si votre but c’est de simplement mettre en ligne de jolies photos et que vous abandonnez le côté « Je vais faire grossir ma communauté pour vivre de ma passion », il existe une alternative libre et open source qui va vous plaire.</p>\n\n\n\n<p>Il s’agit de <a href=\"https://pixelfed.org/\" target=\"_blank\" rel=\"noopener\"><strong>PixelFed</strong></a> qui n’est ni plus ni moins qu’un clone web d’Instagram permettant de partager vos photos de manière fédérée (via le Fediverse) avec d’autres outils comme Mastodon, Nextcloud ou encore Peertube. L’astuce c’est que vous pouvez installer votre propre instance sur votre propre serveur et ainsi ne dépendre d’aucune société pour le stockage et la modération de vos photos. Toutes les instances étant liées les unes aux autres, chaque utilisateur peut via son instance accéder à l’ensemble des photos de son instance et de toutes les autres instances.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img width=\"1024\" height=\"760\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221007-cnk-2.webp\" alt=\"\" class=\"wp-image-130742\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221007-cnk-2.webp 1024w, https://korben.info/app/uploads/2022/10/SCR-20221007-cnk-2-300x223.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221007-cnk-2-768x570.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>L’outil permet ainsi de présenter les timelines des inscrits au service, mais également d’explorer le contenu d’autres créateurs. Comme on reste dans l’esprit Instagram, PixelFed met également à disposition une série de filtres que vous pourrez appliquer sur vos images et même si ça va de soi, l’outil est conçu pour respecter votre vie privée et n’embarque aucun tracker.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221007-cnv.webp\" alt=\"\" class=\"wp-image-130741\" width=\"832\" height=\"792\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221007-cnv.webp 807w, https://korben.info/app/uploads/2022/10/SCR-20221007-cnv-300x286.webp 300w, https://korben.info/app/uploads/2022/10/SCR-20221007-cnv-768x731.webp 768w\" sizes=\"(max-width: 832px) 100vw, 832px\" /></figure></div>\n\n\n<p>Si ça vous chauffe d’essayer, il y a une <a href=\"https://fedidb.org/software/pixelfed\" target=\"_blank\" rel=\"noopener\">liste d’instances ici</a> et si vous voulez l’installer sur une machine, <a href=\"https://docs.pixelfed.org/running-pixelfed/\" target=\"_blank\" rel=\"noopener\">c’est par ici que ça se passe</a>.</p>\n",

Mais la vérité est ailleurs surtout pour les développeurs qui savent que le monde se divise en réalité entre le Frontend et le Backend.</p>\n\n\n\n<p>Et pour que ces 2 faces d’une même pièce puissent « discuter », il nous faut des API. API, ça veut dire Application Programming Interface et c’est tout simplement un ensemble d’instructions permettant aux applications de communiquer entre elles. Maintenant des types d’API, il y en a des tonnes, mais je vous propose qu’aujourd’hui on s’intéresse aux API qui respectent le standard architectural REST. </p>\n\n\n\n<p>En effet, quand on travaille en tant que développeur, on ne peut pas passer à côté des API REST, tant cette pratique est très répandue. Si vous débutez dans votre métier, c’est forcement quelque chose que vous devez apprendre et maitriser. De la même manière, quand on débute sa carrière de développeur ou qu’on a déjà beaucoup d’années au compteur mais qu’on ne connaît pas sa valeur sur le marché de l’emploi, il est bon de connaître la grille des salaires en France. Ça tombe bien puisque <strong><a href=\"https://join.talent.io/tech-salary-report-fr?utm_source=korben&utm_medium=partnership&utm_campaign=Q4&utm_content=article1\" target=\"_blank\" rel=\"noopener\">talent.io a mis en ligne une étude des salaires de la tech en 2022</a></strong> pour que vous puissiez déterminer si votre salaire est correct ou sous évalué.</p>\n\n\n\n<p>Je vous invite à vous plonger dedans afin de savoir où vous vous situez sur cette grille des salaires.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><a href=\"https://join.talent.io/tech-salary-report-fr?utm_source=korben&utm_medium=partnership&utm_campaign=Q4&utm_content=article1\"><img src=\"https://me.korben.info/w96-talent-bun\" alt=\"\" width=\"733\" height=\"484\"/></a></figure></div>\n\n\n<h2>C’est quoi une API RESTful ?</h2>\n\n\n\n<p>REST, ça veut dire « Representational State Transfer ». Lorsqu’une API respecte les contraintes de REST, on parle alors d’une API RESTful.</p>\n\n\n\n<p>Quand un développeur veut créer une API RESTful, il doit alors respecter les contraintes édictées par REST, notamment sur le fait que son API doit fonctionner au travers du protocole HTTP et de ses verbes (GET, POST…etc.) et que les requêtes et les réponses de l’API soient dans un format texte tels que JSON, HTML, XML…etc.</p>\n\n\n\n<p>Les API RESTful sont alors mises à disposition des applications via ce qu’on appelle des endpoints. Un endpoint est un assemblage de 2 choses : une URI et un verbe HTTP.</p>\n\n\n\n<p>Admettons que j’ai une API qui permette de lister des utilisateurs, mais également d’en créer des nouveaux.</p>\n\n\n\n<p>L’URI de mon API est la suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>https://url.com/api/user</code></pre>\n\n\n\n<p>Le but du jeu, c’est d’appeler par exemple ce endpoint avec le verbe GET pour obtenir une liste de tous les utilisateurs.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>GET: /user/</code></pre>\n\n\n\n<p>Ou pour ajouter un nouvel utilisateur, on peut utiliser le verbe POST comme ceci, en transmettant un bout de JSON contenant toutes les informations liées à l’utilisateur qu’on souhaite créer (nom, prénom…etc.) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>POST: /user/</code></pre>\n\n\n\n<p>L’idée là, c’est de vous montrer qu’on peut interagir avec l’API à l’aide de différents verbes HTTP. Get peut être assimilé au verbe « lire », POST au verbe « créer », PUT et PATCH au verbe « Mettre à jour » et DELETE au verbe « supprimer ». C’est aussi simple que cela. Et en retour le serveur peut alors répondre avec des codes de status HTTP classiques comme 200, 201, 2002…etc. pour dire que tout est OK, ou des codes de redirection 3xx, d’erreur client 4xx ou d’erreur serveur 5xx.</p>\n\n\n\n<p>En ce qui concerne le format utilisé par les requêtes et les réponses, vous pouvez utiliser du texte, peu importe son format (html, xml.etc.), mais par convention, on utilise surtout du JSON (JavaScript Object Notation).</p>\n\n\n\n<h2>Et JSON ?</h2>\n\n\n\n<p>Le JSON a la particularité d’être facile à lire et à écrire pour les humains et est utilisé pour enregistrer des données dans des bases de données, mais également pour transmettre ces données entre les applications. C’est pourquoi on l’utilise dans les API RESTful.</p>\n\n\n\n<p>Le JSON est une collection de paires nom / valeur qui sont ordonnées dans une liste. Ainsi les valeurs contenues dans le JSON peuvent être une chaine de caractère (string), un nombre, mais également des objets JSON, des tableaux de valeurs (Array), des booléens (true / false) ou la fameuse valeur null.</p>\n\n\n\n<p>Voilà concernant les grands principes des API RESTful.</p>\n\n\n\n<h2>Comment créer votre première API RESTful ?</h2>\n\n\n\n<p>Maintenant je vous propose qu’on apprenne à en créer une de zéro. Vous allez voir, c’est super simple.</p>\n\n\n\n<p>Pour cette démo, j’ai choisi d’utiliser Python comme d’habitude. Et je vais importer dans mon code le framework <a href=\"https://palletsprojects.com/p/flask/\" target=\"_blank\" rel=\"noopener\">Flask</a> qui va me permettre de faire monter mon API RESTful très facilement. Installez Flask comme ceci :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>pip3 install flask-restful</code></pre>\n\n\n\n<p>Pour tester l’API, nous allons utiliser un outil qui permet à la fois de balancer nos requêtes et de voir si les réponses correspondent bien. L’un des plus connus s’appelle Postman et c’est gratuit en version de base pour tester. L’application Desktop de Postman <a href=\"https://www.postman.com/downloads/\" target=\"_blank\" rel=\"noopener\">est disponible ici</a>.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"1024\" height=\"671\" src=\"https://me.korben.info/3y1-talent-API-REST\" alt=\"\"/></figure></div>\n\n\n<p>Ensuite, nous allons définir ce que va faire notre API. Ce sera quelque chose d’assez simple permettant de créer, supprimer, lire et mettre à jour des données. Admettons que j’ai un site sur lequel je dois référencer des produits. Chacun de ces produits aura un id, un nom, un prix et une catégorie.</p>\n\n\n\n<h2>Le code de votre première API</h2>\n\n\n\n<p>Je vais donc créer un fichier productAPI.py et je vais importer Flask comme ceci avec ses imports spécifiques aux API et au parsing JSON :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>from flask import Flask\nfrom flask_restful import Resource, Api, reqparse\n\napp = Flask(__name__)\napi = Api(app)</code></pre>\n\n\n\n<p>Puis je vais créer une espèce de mini base de données JSON directement dans mon code afin d’y référencer mes produits :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>products = [\n { \"id\": 1, \"name\": \"Stylo 4 couleurs\", \"price\": 10, \"category\": \"Papeterie\" },\n { \"id\": 2, \"name\": \"Cahier vert\", \"price\": 20, \"category\": \"Papeterie\" },\n { \"id\": 3, \"name\": \"Télévision 4K\", \"price\": 30, \"category\": \"Tech\" },\n { \"id\": 4, \"name\": \"Souris sans fil\", \"price\": 40, \"category\": \"Tech\" },\n { \"id\": 5, \"name\": \"Ananas\", \"price\": 50, \"category\": \"Alimentaire\" },\n { \"id\": 6, \"name\": \"Kinder Bueno\", \"price\": 60, \"category\": \"Alimentaire\" },\n { \"id\": 7, \"name\": \"Chemise de président\", \"price\": 70, \"category\": \"Textile\" },\n { \"id\": 8, \"name\": \"T-shirt de punk\", \"price\": 80, \"category\": \"Textile\" },\n { \"id\": 9, \"name\": \"Tournevis bleu\", \"price\": 90, \"category\": \"Bricolage\" },\n { \"id\": 10, \"name\": \"Marteau rouge\", \"price\": 100, \"category\": \"Bricolage\" }\n ]</code></pre>\n\n\n\n<p>Maintenant on va créer une classe Product qui sera vu comme un endpoint au niveau de notre API. Et dans cette class, nous allons placer nos 4 fonctions correspondantes aux 4 verbes HTTP dont je vous ai parlé plus haut.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>class Product(Resource):\n\n def get(self, id):\n\n def post(self, id):\n\n def put(self, id):\n\n def delete(self, id):</code></pre>\n\n\n\n<p>La structure de base de notre API est OK. Maintenant, on va définir chacune de ces fonctions en commençant par la fonction get utilisée pour récupérer les informations d’un produit à partir de son ID. Comme vous pouvez le voir, on fait une boucle « for » qui va parcourir l’ensemble des produits et si l’ID correspond à ce qui spécifié dans la requête, on renvoie l’objet « product » avec son code HTTP 200 et si ce n’est pas le cas, on renvoie un message « Produit introuvable » accompagné d’un code d’erreur HTTP 404 qui correspond à une ressource non trouvée.</p>\n\n\n\n<pre class=\"wp-block-code\"><code> def get(self, id):\n for product in products:\n if (id == product[\"id\"]):\n return product, 200\n return \"Produit introuvable\", 404</code></pre>\n\n\n\n<p>La fonction suivante va nous permettre de créer un nouveau produit. La donnée utilisée dans la requête étant structurée en JSON, cette fonction va utiliser le parseur de Flask pour extraire toutes les données du JSON et les ajouter à notre tableau de produits : </p>\n\n\n\n<pre class=\"wp-block-code\"><code> def post(self, id):\n parser = reqparse.RequestParser()\n parser.add_argument(\"name\")\n parser.add_argument(\"price\")\n parser.add_argument(\"category\")\n args = parser.parse_args()\n\n for product in products:\n if (id == product[\"id\"]):\n return \"Ce produit {} existe deja\".format(id), 400\n\n product = {\n \"id\": id,\n \"name\": args[\"name\"],\n \"price\": args[\"price\"],\n \"category\": args[\"category\"]\n }\n products.append(product)\n return product, 201</code></pre>\n\n\n\n<p>Une fois que le produit est créé, on retourne le code 201 qui veut dire que la création s’est bien déroulée. Et si le produit existait déjà avec cet ID, on renvoie le code 400 avec un message d’erreur.</p>\n\n\n\n<p>La fonction put suivante est assez similaire puisqu’elle permet à la fois de créer un nouveau produit (si l’id n’est pas encore utilisé) ou de mettre à jour un produit existant.</p>\n\n\n\n<pre class=\"wp-block-code\"><code> def put(self, id):\n parser = reqparse.RequestParser()\n parser.add_argument(\"name\")\n parser.add_argument(\"price\")\n parser.add_argument(\"category\")\n args = parser.parse_args()\n\n for product in products:\n if (id == product[\"id\"]):\n product[\"name\"] = args[\"name\"]\n product[\"price\"] = args[\"price\"]\n product[\"category\"] = args[\"category\"]\n return product, 200\n\n product = {\n \"id\": id,\n \"name\": args[\"name\"],\n \"price\": args[\"price\"],\n \"category\": args[\"category\"]\n }\n products.append(product)\n return product, 201</code></pre>\n\n\n\n<p>Enfin, vous l’aurez compris, la fonction delete permettra de supprimer un enregistrement à partir de son ID.</p>\n\n\n\n<pre class=\"wp-block-code\"><code> def delete(self, id):\n global products\n products = [product for product in products if product[\"id\"] != id]\n return \"{} is deleted.\".format(id), 200</code></pre>\n\n\n\n<p>Une fois ces fonctions définies, il ne reste plus qu’à spécifier le format de l’URI qui sera utilisé pour appeler l’API et lancer l’API (en mode debug pour démarrer). Le paramètre <int:id> permet d’indiquer que dans le chemin du endpoint, on peut ajouter une variable acceptée par l’API (ici l’ID du produit).</p>\n\n\n\n<pre class=\"wp-block-code\"><code>api.add_resource(Product, \"/product/<int:id>\")\napp.run(debug=True)</code></pre>\n\n\n\n<h2>Tester l’API avec Postman</h2>\n\n\n\n<p>Enfin, il ne reste plus qu’à lancer le script python à l’aide de la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>python3 productAPI.py</code></pre>\n\n\n\n<p>Le serveur web de Flask se lancera alors et vous verrez apparaitre une URL locale que vous pourrez appeler dans Postman pour ensuite tester votre API.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"1024\" height=\"163\"

produit (ce n’est pas l’idéal bien sûr, car le principe d’un nouvel ID c’est qu’il soit généré directement par le code de l’API, mais c’est pour illustrer mon exemple).</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221014-lcg.webp\" alt=\"\"

/></figure></div>\n\n\n<h2>Et ensuite ?</h2>\n\n\n\n<p>Vous l’aurez compris, ce n’est vraiment pas compliqué à développer. Ici on est sur un exemple simple, mais ensuite, vous devrez pourquoi pas sortir vos données d’une base de données, penser à correctement gérer les erreurs et faire preuve de rigueur dans la structure de vos endpoints. Par exemple, dans mon endpoint, l’URI est xxxx/product/. J’aurais pu faire mieux en respectant la convention et en mettant/products/ au pluriel. Car en cas de GET, je peux aussi demander à récupérer l’ensemble des produits existants. Dans ce cas, je dois modifier ma fonction GET comme ceci :</p>\n\n\n\n<pre class=\"wp-block-code\"><code> def get(self, id):\n if (id == 0):\n return products, 200\n else:\n for product in products:\n if (id == product[\"id\"]):\n return product, 200\n return \"Product not found\", 404</code></pre>\n\n\n\n<p>Ainsi, en passant l’id 0 lors de mon GET, je récupérerai alors tous les produits.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"687\" height=\"768\" src=\"https://korben.info/app/uploads/2022/10/SCR-20221014-m99.webp\" alt=\"\" class=\"wp-image-130939\" srcset=\"https://korben.info/app/uploads/2022/10/SCR-20221014-m99.webp 687w, https://korben.info/app/uploads/2022/10/SCR-20221014-m99-268x300.webp 268w\" sizes=\"(max-width: 687px) 100vw, 687px\" /></figure></div>\n\n\n<p>N’oubliez pas également de documenter l’ensemble de votre API afin de vous y retrouver et surtout d’indiquer à d’autres développeurs, comment l’intégrer.</p>\n\n\n\n<p>Voilà, j’espère que cette petite initiation et explications aux API RESTful vous aura intéressé et donné envie de vous y mettre plus sérieusement. Peut-être changer un peu votre façon de coder, voire carrément changer de job pour trouver une équipe plus agile et plus au fait des pratiques de dev modernes. Et pourquoi pas en profiter pour continuer à évoluer dans les technologies, ou obtenir un meilleur salaire. C’est une démarche qui peut s’avérer assez compliquée, stressante parfois, tant on a envie de trouver un travail qui nous corresponde. On peut souhaiter avoir un travail plus proche de chez soi voire en télétravail complet, un meilleur salaire, une meilleure ambiance au travail, ou même tout ça à la fois (mais ce n’est pas forcément facile à trouver).</p>\n\n\n\n<p>Heureusement, talent.io est là pour vous aider. Il vous suffit de <strong><a href=\"https://join.talent.io/tech-salary-report-fr?utm_source=korben&utm_medium=partnership&utm_campaign=Q4&utm_content=article1\" target=\"_blank\" rel=\"noopener\">créer un compte sur la plateforme talent.io</a></strong> en quelques clics pour ensuite recevoir des offres de la part d’entreprises qui correspondent à vos critères précis et qui affichent un salaire d’entrée de jeu. talent.io est vraiment le moyen le plus simple de trouver son prochain job tech, d’ailleurs les inscrits trouvent leur emploi en 20 jours en moyenne.</p>\n",

On s’affronte par équipe de 4 en balançant de l’encre partout ; et c’est l’équipe qui aura colorié le plus de territoire de sa propre couleur qui gagne la partie. C’est ici que le jeu se démarque, car même si vous ne savez pas très bien viser, vous pouvez être utile à votre équipe. 😉</p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Splatoon 3 – Maintenant disponible !

On peut facilement varier les plaisirs !</p>\n\n\n\n<p>Les modes de jeu, eux aussi, sont variés. Entre les matchs classiques, les parties « ranked » (matchs « anarchie » avec différentes règles du jeu possible !), ou bien en coopératif… Il y a de quoi faire ! On a même un jeu de carte assez cool, où l’on construit son propre deck. 🤓</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"575\" src=\"https://korben.info/app/uploads/2022/10/Splatoon3_Overview_MoreWays_Tableturf_Scr_02-1024x575.jpg\" alt=\"\" class=\"wp-image-130718\" srcset=\"https://korben.info/app/uploads/2022/10/Splatoon3_Overview_MoreWays_Tableturf_Scr_02-1024x575.jpg 1024w, https://korben.info/app/uploads/2022/10/Splatoon3_Overview_MoreWays_Tableturf_Scr_02-300x168.jpg 300w, https://korben.info/app/uploads/2022/10/Splatoon3_Overview_MoreWays_Tableturf_Scr_02-768x431.jpg 768w, https://korben.info/app/uploads/2022/10/Splatoon3_Overview_MoreWays_Tableturf_Scr_02.jpg 1268w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Le mode solo n’est pas en reste, il s’agit d’un tutorial géant mais vraiment sympa, où l’on alterne entre phases d’exploration et épreuves, nous faisant découvrir un large éventail d’armes et de techniques.

Y a eu de vrais efforts pour rendre l’expérience plus agréable. Quelques autres apports, en vrac :</p>\n\n\n\n<ul><li>Un meilleur lobby (avec entrainement pendant l’attente, etc.)</li><li>De nouveaux mouvements pour nos calamars</li><li>Un casier à décorer avec des stickers</li><li>Nouvelles armes, maps, cosmétiques…</li><li>Les matchs à 3 équipes !</li></ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_05-1024x576.jpg\" alt=\"\" class=\"wp-image-130720\" srcset=\"https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_05-1024x576.jpg 1024w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_05-300x169.jpg 300w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_05-768x432.jpg 768w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_05-1536x864.jpg 1536w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_05.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Concrètement, ce n’est pas une suite révolutionnaire, mais elle améliore et apporte plein de petites choses. Au final, quand on met tout bout à bout, ça fait une grosse différence. Si vous aimez les shooters, c’est super original et surtout : très fun !</p>\n\n\n\n<h2 class=\"has-text-align-center\"><a href=\"https://amzn.to/3e9cJAw\" target=\"_blank\" rel=\"noopener\">Acheter Splatoon 3 sur Nintendo Switch</a></h2>\n",

C’est à dire qu’on fait la course, mais en se goinfrant le plus possible sur le chemin : car c’est la personne qui aura dévoré le plus de sucreries à la fin des 4 manches qui aura gagné. 😋 Deux manches sur circuits (à la manière d’un Mario Kart en plus léger), et deux manches en arène (où on ramasse un max de gourmandises en essayant de faire tomber les autres pour piquer les leurs) : à la fin on pèse les Kirbys et que le plus lourd gagne !</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_2_4-1024x576.jpg\" alt=\"\" class=\"wp-image-130668\" srcset=\"https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_2_4-1024x576.jpg 1024w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_2_4-300x169.jpg 300w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_2_4-768x432.jpg 768w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_2_4-1536x864.jpg 1536w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_2_4.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Le gameplay se résume à l’essentiel : déplacement, saut, attaque spéciale (grâce aux bonus récupérés ici et là). Il y a juste la gestion de l’inertie, propre à la petite boule qu’on dirige, qui va demander quelques petites minutes d’adaptation : le concept est aussi simple que la prise en main est immédiate, c’est un party-game d’une efficacité assez redoutable. Et tellement mignon… 🥰</p>\n\n\n\n<p>Niveau contenu, en terme de modes de jeux ou nombre de circuits/niveaux, là aussi on se contente de l’essentiel. Pas de quoi être déçu, car c’est cohérent avec le prix affiché (15€). Pour les fous furieux, sachez qu’il y a des tonnes de petits cosmétiques et autres à débloquer. 😀</p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_3_1-1024x576.jpg\" alt=\"\" class=\"wp-image-130669\" srcset=\"https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_3_1-1024x576.jpg 1024w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_3_1-300x169.jpg 300w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_3_1-768x432.jpg 768w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_3_1-1536x864.jpg 1536w, https://korben.info/app/uploads/2022/10/NSwitchDS_KirbysDreamBuffet_3_1.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1146385180\"><div id='optidigital-adslot-Content_2' style='display:none;' class=\"Content_2\"></div>\r\n<div id='optidigital-adslot-Mobile_Pos2' style='display:none;' class=\"Mobile_Pos2\"></div></div><p>Jouable à 4 en ligne ou en local (chacun sa console), mais pas en écran splitté sur la même console : là on est limités à 2 joueurs.

Ça m’a bien aidé en tout cas, et j’ai pu me décider entre le <a href=\"https://amzn.to/3reaKxC\" target=\"_blank\" rel=\"noopener\">Samsung 970 Evo Nvme M.2</a> et le <a href=\"https://amzn.to/3fnhzKU\" target=\"_blank\" rel=\"noopener\">Samsung 980 Pro Nvme M.2</a> =:-)</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/09/ssd.webp\" alt=\"\" class=\"wp-image-130532\" width=\"569\" height=\"299\" srcset=\"https://korben.info/app/uploads/2022/09/ssd.webp 1000w, https://korben.info/app/uploads/2022/09/ssd-300x158.webp 300w, https://korben.info/app/uploads/2022/09/ssd-768x405.webp 768w\" sizes=\"(max-width: 569px) 100vw, 569px\" /></figure></div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/09/userbench.webp\" alt=\"\" class=\"wp-image-130533\" width=\"557\" height=\"227\" srcset=\"https://korben.info/app/uploads/2022/09/userbench.webp 1000w, https://korben.info/app/uploads/2022/09/userbench-300x123.webp 300w, https://korben.info/app/uploads/2022/09/userbench-768x314.webp 768w\" sizes=\"(max-width: 557px) 100vw, 557px\" /></figure></div>\n\n\n<p>Bref, génial pour ne plus se tromper et faire le bon choix en cas d’upgrade de votre machine !</p>\n",
