Here the process can be represented like this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523unexpected1img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523unexpected1img2.png' alt='' title='' width='112' height='290'> </div>\n</p></div>\n<p>We can think of the yellow boxes in this picture as corresponding to “evaluation events” that transform one “state of the expression” (represented by a blue box) to another, eventually reaching the “fixed point” 12.</p>\n<p>And so far this may all seem very simple. But actually there are many surprisingly complicated and deep issues and questions. For example, to what extent can the evaluation events be applied in different orders, or in parallel? Does one always get the same answer? What about non-terminating sequences of events? And so on.<span id=\"more-53756\"></span></p>\n<p>I was first exposed to such issues more than 40 years ago—when I was working on the design of the evaluator for the <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">SMP system</a> that was the forerunner of <a href=\"https://www.wolfram.com/mathematica/\">Mathematica</a> and the Wolfram Language. And back then I came up with pragmatic, practical solutions—many of which we still use today. But I was never satisfied with the whole conceptual framework. And I always thought that there should be a much more principled way to think about such things—that would likely lead to all sorts of important generalizations and optimizations. </p>\n<p>Well, more than 40 years later I think we can finally now see how to do this. And it’s all based on ideas from our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a>—and on a fundamental correspondence between what’s happening at the lowest level in all physical processes and in expression evaluation. Our Physics Project implies that ultimately the universe <a href=\"https://writings.stephenwolfram.com/2020/04/finally-we-may-have-a-path-to-the-fundamental-theory-of-physics-and-its-beautiful/#time\">evolves through a series of discrete events</a> that transform the underlying structure of the universe (say, represented as a hypergraph)—just like evaluation events transform the underlying structure of an expression.</p>\n<p>And given this correspondence, we can start applying ideas from physics—like ones about spacetime and quantum mechanics—to questions of expression evaluation. Some of what this will lead us to is deeply abstract. But some of it has immediate practical implications, notably for parallel, distributed, nondeterministic and quantum-style computing. And from seeing how things play out in the rather accessible and concrete area of expression evaluation, we’ll be able to develop more intuition about fundamental physics and about other areas (like <a href=\"https://www.wolframscience.com/metamathematics/\">metamathematics</a>) where the ideas of our Physics Project can be applied.</p>\n<h2 id=\"causal-graphs-and-spacetime\">Causal Graphs and Spacetime</h2>\n<p>The <a href=\"https://reference.wolfram.com/language/tutorial/Evaluation.html\">standard evaluator in the Wolfram Language</a> applies evaluation events to an expression in a particular order. But typically multiple orders are possible; for the example above, there are three:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img1.png' alt='' title='' width='452' height='209'> </div>\n</p></div>\n<p>So what determines what orders are possible? There is ultimately just one constraint: the causal dependencies that exist between events. The key point is that a given event cannot happen unless all the inputs to it are available, i.e. have already been computed. So in the example here, the <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img2.png' width= '62' height='12' align='absmiddle'></span> evaluation event cannot occur unless the <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img3.png' width= '65' height='12' align='absmiddle'></span> one has already occurred. And we can summarize this by “drawing a causal edge” from the <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img4.png' width= '65' height='12' align='absmiddle'></span> event to the <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img5.png' width= '62' height='12' align='absmiddle'></span> one. Putting together all these “causal relations”, we can make a <a href=\"https://www.wolframphysics.org/technical-introduction/additional-material/appendix-graph-types/\" target=\"_blank\" rel=\"noopener\">causal graph</a>, which in the example here has the simple form (where we include a special “Big Bang” initial event to create the original expression that we’re evaluating):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img6.png' alt='' title='' width='220' height='175'> </div>\n</p></div>\n<p>What we see from this causal graph is that the events on the left must all follow each other, while the event on the right can happen “independently”. And this is where we can start making an analogy with physics. Imagine our events are laid out in spacetime. The events on the left are “timelike separated” from each other, because they are constrained to follow one after another, and so must in effect “happen at different times”. But what about the event on the right? We can think of this as being “spacelike separated” from the others, and happening at a “different place in space” asynchronously from the others. </p>\n<p>As a quintessential example of a timelike chain of events, consider making the definition</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723causal2Aimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img8.png' alt='' title='' width='102' height='14'> </div>\n</p></div>\n<p>and then generating the causal graph for the events associated with evaluating <tt>f[f[f[1]]]</tt> (i.e. <tt><a href=\"http://reference.wolfram.com/language/ref/Nest.html\">Nest</a>[f, 1, 3]</tt>): </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img9.png' alt='' title='' width='70' height='302'> </div>\n</p></div>\n<p>A straightforward way to get spacelike events is just to “build in space” by giving an expression like <tt>f[1]</tt> <tt>+</tt> <tt>f[1]</tt> <tt>+</tt> <tt>f[1]</tt> that has parts that can effectively be thought of as being explicitly “laid out in different places”, like the cells in a <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-1--how-do-simple-programs-behave\">cellular automaton</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img10.png' alt='' title='' width='359' height='163'> </div>\n</p></div>\n<p>But one of the major lessons of our Physics Project is that it’s possible for space to “emerge dynamically” from the evolution of a system (in that case, by successive rewriting of hypergraphs). And it turns out very much the same kind of thing can happen in expression evaluation, notably with recursively defined functions. </p>\n<p>As a simple example, consider the standard definition of Fibonacci numbers:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723causal2Aimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img12.png' alt='' title='' width='326' height='14'> </div>\n</p></div>\n<p>With this definition, the causal graph for the evaluation of <tt>f[3]</tt> is then:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img13.png' alt='' title='' width='433' height='328'> </div>\n</p></div>\n<p>For <tt>f[5]</tt>, dropping the “context” of each event, and showing only what changed, the graph is</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img14.png' alt='' title='' width='540' height='536'> </div>\n</p></div>\n<p>while for <tt>f[8]</tt> the structure of the graph is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img15.png' alt='' title='' width='482' height='482'> </div>\n</p></div>\n<p>So what is the significance of there being spacelike-separated parts in this graph? At a practical level, a consequence is that those parts correspond to subevaluations that can be done independently, for example in parallel. All the events (or subevaluations) in any timelike chain must be done in sequence. But spacelike-separated events (or subevaluations) don’t immediately have a particular relative order. The whole graph can be thought of as defining a partial ordering for all events—with the events forming a partially ordered set (poset). Our “timelike chains” then correspond to what are usually called chains in the poset. The antichains of the poset represent possible collections of events that can occur “simultaneously”.</p>\n<p>And now there’s a deep analogy to physics. Because just like in the standard relativistic approach to spacetime, we can define a sequence of “spacelike surfaces” (or hypersurfaces in 3 + 1-dimensional spacetime) that correspond to possible successive “simultaneity surfaces” where events can consistently be done simultaneously. Put another way, <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\">any &#8220;foliation&#8221; of the causal graph</a> defines a sequence of “time steps” in which particular collections of events occur—as in for example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img16.png' alt='' title='' width='661' height='204'> </div>\n</p></div>\n<p>And just like in relativity theory, different foliations correspond to different choices of reference frames, or what amount to different choices of “space and time coordinates”. But at least in the examples we’ve seen so far, the “final result” from the evaluation is always the same, regardless of the foliation (or reference frame) we use—just as we expect when there is relativistic invariance.</p>\n<p>As a slightly more complex—but ultimately very similar—example, consider the <a href=\"https://www.wolframscience.com/nks/p130--recursive-sequences/\">nestedly recursive function</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723causal2Aimg15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img18.png' alt='' title='' width='256' height='38'> </div>\n</p></div>\n<p>Now the causal graph for <tt>f[12]</tt> has the form</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img19_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523causal2img19.png' alt='' title='' width='353' height='353'> </div>\n</p></div>\n<p>which again has both spacelike and timelike structure.</p>\n<h2 id=\"foliations-and-the-definition-of-time\">Foliations and the Definition of Time</h2>\n<p>Let’s go back to our first example above—the evaluation of (1 + (2 + 2)) + (3 + 4). As we saw above, the causal graph in this case is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img1.png' alt='' title='' width='214' height='169'> </div>\n</p></div>\n<p>The standard Wolfram Language evaluator makes these events occur in the following order:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img2.png' alt='' title='' width='212' height='167'> </div>\n</p></div>\n<p>And by applying events in this order starting with the initial state, we can reconstruct the sequence of states that will be reached at each step by this particular evaluation process (where now we’ve highlighted in each state the part that’s going to be transformed at each step):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img3.png' alt='' title='' width='112' height='274'> </div>\n</p></div>\n<p>Here’s the standard evaluation order for the Fibonacci number <tt>f[3]</tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img4.png' alt='' title='' width='293' height='257'> </div>\n</p></div>\n<p>And here’s the sequence of states generated from this sequence of events:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img5.png' alt='' title='' width='158' height='289'> </div>\n</p></div>\n<p>Any valid evaluation order has to eventually visit (i.e. apply) all the events in the causal graph. Here’s the path that’s traced out by the standard evaluation order on the causal graph for <tt>f[8]</tt>. As we’ll discuss later, this corresponds to a depth-first scan of the (directed) graph:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img6.png' alt='' title='' width='346' height='345'> </div>\n</p></div>\n<p>But let’s return now to our first example. We’ve seen the order of events used in the standard Wolfram Language evaluation process. But there are actually three different orders that are consistent with the causal relations defined by the causal graph (in the language of posets, each of these is a “total ordering”):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img7.png' alt='' title='' width='573' height='136'> </div>\n</p></div>\n<p>And for each of these orders we can reconstruct the sequence of states that would be generated:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img8.png' alt='' title='' width='444' height='125'> </div>\n</p></div>\n<p>Up to this point we’ve always assumed that we’re just applying one event at a time. But whenever we have spacelike-separated events, we can treat such events as “simultaneous”—and applied at the same point. And—just like in relativity theory—there are typically multiple possible choices of “simultaneity surfaces”. Each one corresponds to a certain foliation of our causal graph. And in the simple case we’re looking at here, there are only two possible (maximal) foliations:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img9.png' alt='' title='' width='455' height='172'> </div>\n</p></div>\n<p>From such foliations we can reconstruct possible total orderings of individual events just by enumerating possible permutations of events within each slice of the foliation (i.e. within each simultaneity surface). But we only really need a total ordering of events if we’re going to apply one event at a time. Yet the whole point is that we can view spacelike-separated events as being “simultaneous”. Or, in other words, we can view our system as “evolving in time”, with each “time step” corresponding to a successive slice in the foliation.</p>\n<p>And with this setup, we can reconstruct states that exist at each time step—interspersed by updates that may involve several “simultaneous” (spacelike-separated) events.

Well, it’s not explicitly here—because it involves doing a single event at a time, while all the foliations here are &#8220;maximal&#8221; in the sense that they aggregate as many events as they can into each spacelike slice. But if we don’t impose this maximality constraint, are there foliations that in a sense “cover” the standard evaluation order? Without the maximality constraint, there turn out in the example we’re using to be not 10 but 1249 possible foliations.

But what if instead one tries to do as many events as possible at a time? Well, that’s what our “maximal foliations” above are about. But one particularly notable case is what corresponds to a breadth-first scan of the causal graph. And this turns out to be covered by the very last maximal foliation we showed above. </p>\n<p>How this works may not be immediately obvious from the picture. With our standard layout for the causal graph, the path corresponding to the breadth-first scan is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img14_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img14.png' alt='' title='' width='310' height='274'> </div>\n</p></div>\n<p>But if we lay out the causal graph differently, the path takes on the much-more-obviously-breadth-first form:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img15.png' alt='' title='' width='268' height='264'> </div>\n</p></div>\n<p>And now using this layout for the various configurations of foliations above we get:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img16.png' alt='' title='' width='625' height='460'> </div>\n</p></div>\n<p>We can think of different layouts for the causal graph as defining different “coordinatizations of spacetime”. If the vertical direction is taken to be time, and the horizontal direction space, then different layouts in effect place events at different positions in time and space. And with the layout here, the last foliation above is “flat”, in the sense that successive slices of the foliation can be thought of as directly corresponding to successive “steps in time”. </p>\n<p>In physics terms, different foliations correspond to different “reference frames”. And the “flat” foliation can be thought of as being like the cosmological rest frame, in which the observer is “at rest with respect to the universe”. In terms of states and events, we can also interpret this another way: we can say it’s the foliation in which in some sense the “largest possible number of events are being packed in at each step”. Or, more precisely, if at each step we scan from left to right, we’re doing every successive event that doesn’t overlap with events we’ve already done at this step:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img17_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img17.png' alt='' title='' width='138' height='335'> </div>\n</p></div>\n<p>And actually this also corresponds to what happens if, instead of using the built-in standard evaluator, we explicitly tell the Wolfram Language to <a href=\"https://reference.wolfram.com/language/ref/ReplaceAll.html\">repeatedly do replacements in expressions</a>. To compare with what we’ve done above, we have to be a little careful in our definitions, using ⊕ and ⊖ as versions of + and – that have to get explicitly evaluated by other rules. But having done this, we get exactly the same sequence of “intermediate expressions” as in the flat (i.e. “breadth-first”) foliation above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092623codeupdateimg7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523foliations3img18.png' alt='' title='' width='491' height='281'> </div>\n</p></div>\n<p>In general, different foliations can be thought of as specifying different “event-selection functions” to be applied to determine what events should occur at the next steps from any given state. At one extreme we can pick single-event-at-a-time event selection functions—and at the other extreme we can pick maximum-events-at-a-time event selection functions. In our Physics Project we have called the states obtained by applying maximal collections of events at a time “<a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/generational-evolution/#p-294\" target=\"_blank\" rel=\"noopener\">generational states</a>”. And in effect these states represent the typical way we parse physical “spacetime”—in which we take in “all of space” at every successive moment of time. At a practical level the reason we do this is that the speed of light is somehow fast compared to the operation of our brains: if we look at our local surroundings (say the few hundred meters around us), light from these will reach us in a microsecond, while it takes our brains milliseconds to register what we’re seeing. And this makes it reasonable for us to think of there being an “instantaneous state of space” that we can perceive “all at once” at each particular “moment in time”.</p>\n<p>But what’s the analog of this when it comes to expression evaluation? We’ll discuss this a little more later. But suffice it to say here that it depends on who or what the “observer” of the process of evaluation is supposed to be. If we’ve got different elements of our states laid out explicitly in arrays, say in a GPU, then we might again “perceive all of space at once”. But if, for example, the data associated with states is connected through chains of pointers in memory or the like, and we “observe” this data only when we explicitly follow these pointers, then our perception won’t as obviously involve something we can think of as &#8220;bulk space&#8221;. But by thinking in terms of foliations (or reference frames) as we have here, we can potentially fit what’s going on into something like space, that seems familiar to us. Or, put another way, we can imagine in effect “programming in a certain reference frame” in which we can aggregate multiple elements of what’s going on into something we can consider as an analog of space—thereby making it familiar enough for us to understand and reason about.</p>\n<h2 id=\"multiway-evaluation-and-multiway-graphs\">Multiway Evaluation and Multiway Graphs</h2>\n<p>We can view everything we’ve done so far as dissecting and reorganizing the standard evaluation process. But let’s say we’re just given certain underlying rules for transforming expressions—and then we apply them in all possible ways. It’ll give us a <a href=\"https://www.wolframscience.com/nks/chap-5--two-dimensions-and-beyond#sect-5-6--multiway-systems\">&#8220;multiway&#8221; generalization of evaluation</a>—in which instead of there being just one path of history, there are many. And in our Physics Project, this is exactly how 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-inevitability-of-quantum-mechanics\">transition from classical to quantum physics works</a>. And as we proceed here, we’ll see a close correspondence between multiway evaluation and quantum processes.</p>\n<p>But let’s start again with our expression (1 + (2 + 2)) + (3 + 4), and consider all possible ways that individual integer addition “events” can be applied to evaluate this expression. In this particular case, the result is pretty simple, and can be represented by a tree that branches in just two places:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523multiway4img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523multiway4img1.png' alt='' title='' width='372' height='295'> </div>\n</p></div>\n<p>But one thing to notice here is that even at the first step there’s an event <img style=\"margin-bottom: -7px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523multiway4img4.png' alt='' title='' width='97' height='27'/> that we’ve never seen before. It’s something that’s possible if we apply integer addition in all possible places.

But there’s a certain redundancy in having all these separate paths<span style=\"font-size:12px\">—</span>because there are multiple instances of the same expression that appear in different places.

And we can imagine setting up foliations in the multiway graph that divide these events into slices. But what is the significance of these slices? When we did the same kind of thing above for causal graphs, we could interpret the slices as representing “instantaneous states laid out in space”. And by analogy we can interpret a slice in the multiway graph as representing “instantaneous states laid out across branches of history”. In the context of our Physics Project, we can then think of these slices as being like superpositions in quantum mechanics, or states “laid out in branchial space”. And, as we’ll discuss later, just as we can think of elements laid out in “space” as corresponding in the Wolfram Language to parts in a symbolic expression (like a list, a sum, etc.), so now we’re dealing with a new kind of way of aggregating states across branchial space, that has to be represented with new language constructs.</p>\n<p>But let’s return to the very simple case of (1 + (2 + 2)) + (3 + 4). Here’s a more complete representation of the multiway evaluation process in this case, including both all the events involved, and the causal relations between them:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523multiway4img17_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523multiway4img17.png' alt='' title='' width='346' height='358'> </div>\n</p></div>\n<p>The “single-way” evaluation process we discussed above uses only part of this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092923codeupdates2img4_copy.txt' data-c2c-type='text/html'><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523multiway4img18.png' alt='' title='' width='346' height='358'> </div>\n</p></div>\n<p>And from this part we can pull out the causal relations between events to reproduce the (“single-way”) causal graph we had before.

And from foliations of this, we can construct possible histories—though now they’re multiway histories, with the states at particular time steps now being what amount to superposition states. </p>\n<p>In the particular case we’re showing here, the multiway causal graph has a very simple structure, consisting essentially just of a bunch of isomorphic pieces. And as we’ll see later, this is an inevitable consequence of the nature of the evaluation we’re doing here, and its property of <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/the-phenomenon-of-causal-invariance/\" target=\"_blank\" rel=\"noopener\">causal invariance</a> (and in this case, confluence).</p>\n<h2 id=\"branchlike-separation\">Branchlike Separation</h2>\n<p>Although what we’ve discussed has already been somewhat complicated, there’s actually been a crucial simplifying assumption in everything we’ve done. We’ve assumed that different transformations on a given expression can never apply to the same part of the expression. Different transformations can apply to different parts of the same expression (corresponding to spacelike-separated evaluation events). But there’s never been a “conflict” between transformations, where multiple transformations can apply to the same part of the same expression. </p>\n<p>So what happens if we relax this assumption? In effect it means that we can generate different “incompatible” branches of history—and we can characterize the events that produce this as “branchlike separated”. And when such branchlike-separated events are applied to a given state, they’ll produce multiple states which we can characterize as “separated in <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/foliations-of-the-multiway-graph-and-the-structure-of-branchial-space/\" target=\"_blank\" rel=\"noopener\">branchial space</a>”, but nevertheless correlated as a result of their “common ancestry”—or, in quantum mechanics terms, “entangled”.</p>\n<p>As a very simple first example, consider the rather trivial function <tt>f</tt> defined by</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723branchlike5Aimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img2.png' alt='' title='' width='77' height='14'> </div>\n</p></div>\n<p>If we evaluate <tt>f[f[0]]</tt> (for any <tt>f</tt>) there are immediately two “conflicting” branches: one associated with evaluation of the “outer <tt>f</tt>”, and one with evaluation of the “inner <tt>f</tt>”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img3.png' alt='' title='' width='170' height='253'> </div>\n</p></div>\n<p>We can indicate branchlike-separated pairs of events by a dashed line:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img4.png' alt='' title='' width='113' height='264'> </div>\n</p></div>\n<p>Adding in causal edges, and merging equivalent states, we get:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img5.png' alt='' title='' width='155' height='337'> </div>\n</p></div>\n<p>We see that some events are causally related.

We’ve talked about separations between events: timelike, spacelike and branchlike. But what about separations between elements of an expression? In something like <tt>{f[0]</tt>, <tt>f[0]</tt>, <tt>f[0]}</tt> it’s reasonable to extend our characterization of separations between events, and say that the <tt>f[0]</tt>&#8217;s in the expression can themselves be considered spacelike separated. But what about in something like <tt>f[f[0]]</tt>? We can say that the <tt>f[_]</tt>&#8217;s here “overlap”—and “conflict” when they are transformed—making them branchlike separated. But the structure of the expression also inevitably makes them “<a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/#causal-graphs-and-the-physicalization-of-combinators\">treelike separated</a>”. We’ll see later how to think about the relation between treelike-separated elements in more fundamental terms, ultimately using hypergraphs. But for now an obvious question is what in general the relation between branchlike-separated elements can be.</p>\n<p>And essentially the answer is that branchlike separation has to “come with” some other form of separation: spacelike, treelike, rulelike, etc. Rulelike separation involves having multiple rules for the same object (e.g. a rule <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img9.png' width= '37' height='9' align='absmiddle'></span> as well as <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092523branchlike5img10.png' width= '39' height='9' align='absmiddle'></span>)—and we’ll talk about this <a href=\"https://writings.stephenwolfram.com/2023/09/expression-evaluation-and-fundamental-physics/#the-rulial-case\">later</a>. With spacelike separation, we basically get branchlike separation when subexpressions “overlap”.

And in this case we were able to take the causal graphs we got, and set up foliations of them where each slice could be thought of as representing a sequential step in time. In effect, what we were doing was to aggregate things so that we could talk about what happens in “all of space” at a particular time.</p>\n<p>But when there’s branchlike separation we can no longer do this. Because now there isn’t a single, consistent “configuration of all of space” that can be thought of as evolving in a single thread through time. Rather, there are “multiple threads of history” that wind their way through the branchings (and mergings) that occur in the multiway graph. One can make foliations in the multiway graph—much like one does in the causal graph. (More strictly, one really needs to make the foliations in the multiway causal graph—but these can be “inherited” by the multiway graph.)</p>\n<p>In physics terms, the (single-way) causal graph can be thought of as a discrete version of ordinary spacetime—with a foliation of it specifying a “reference frame” that leads to a particular identification of what one considers space, and what time. But what about the multiway causal graph? In effect, we can imagine that it defines a new, branchial “direction”, in addition to the spatial direction. Projecting in this branchial direction, we can then think of getting a kind of branchial analog of spacetime that we can call branchtime. And when we construct the multiway graph, we can basically imagine that it’s a representation of branchtime.</p>\n<p>A particular slice of a foliation of the (single-way) causal graph can be thought of as corresponding to an “instantaneous state of (ordinary) space”. So what does a slice in a foliation of the multiway graph represent? It’s effectively a branchial or multiway combination of states—a collection of states that can somehow all exist “at the same time”. And in physics terms we can interpret it as a quantum superposition of states. </p>\n<p>But how does all this work in the context of expressions? The parts of a single expression like <nobr><em>a</em> <tt>+</tt> <em>b</em> <tt>+</tt> <em>c</em> <tt>+</tt> <em>d</em></nobr> or <tt>{</tt><em>a</em><tt>,</tt> <em>b</em><tt>,</tt> <em>c</em><tt>,</tt> <em>d</em><tt>}</tt> can be thought of being spacelike separated, or in effect “laid out in space”. But what kind of a thing has parts that are “laid out in branchial space”? It’s a new kind of fundamentally multiway construct. We’re not going to explore it too much here, but in the Wolfram Language we might in future call it <tt>Multi</tt>. And just as <tt>{</tt><em>a</em><tt>,</tt> <em>b</em><tt>,</tt> <em>c</em><tt>,</tt> <em>d</em><tt>}</tt> (or <tt><a href=\"http://reference.wolfram.com/language/ref/List.html\">List</a></tt><tt>[</tt><em>a</em><tt>,</tt> <em>b</em><tt>,</tt> <em>c</em><tt>,</tt> <em>d</em><tt>]</tt>) can be thought of as representing <em>a</em>, <em>b</em>, <em>c</em>, <em>d</em> “laid out in space”, so now <tt>Multi</tt><tt>[</tt><em>a</em><tt>,</tt> <em>b</em><tt>,</tt> <em>c</em><tt>,</tt> <em>d</em><tt>]</tt> would represent <nobr><em>a</em>, <em>b</em>, <em>c</em>, <em>d</em></nobr> “laid out branchial space”.</p>\n<p>In ordinary evaluation, we just generate a specific sequence of individual expressions. But in multiway evaluation, we can imagine that we generate a sequence of <tt>Multi</tt> objects. In the examples we’ve seen so far, we always eventually get a <tt>Multi</tt> containing just a single expression. But we’ll soon find out that that’s not always how things work, and we can perfectly well end up with a <tt>Multi</tt> containing multiple expressions.</p>\n<p>So what might we do with a <tt>Multi</tt>? In a typical “nondeterministic computation” we probably want to ask: “Does the <tt>Multi</tt> contain some particular expression or pattern that we’re looking for?” If we imagine that we’re doing a “probabilistic computation” we might want to ask about the frequencies of different kinds of expressions in the <tt>Multi</tt>. And if we&#8217;re doing quantum computation with the normal formalism of quantum mechanics, we might want to tag the elements of the <tt>Multi</tt> with “quantum amplitudes” (that, yes, in our model presumably have magnitudes determined by path counting in the multiway graph, and phases representing the “positions of elements in branchial space”). And in a traditional quantum measurement, the concept would typically be to determine a projection of a <tt>Multi</tt>, or in effect an inner product of <tt>Multi</tt> objects. (And, yes, if one knows only that projection, it’s not going to be enough to let one unambiguously continue the “multiway computation”; the quantum state has in effect been “collapsed”.)</p>\n<h2 id=\"is-there-always-a-definite-result?\">Is There Always a Definite Result?</h2>\n<p>For an expression like (1 + (2 + 2)) + (3 + 4) it doesn’t matter in what order one evaluates things; one always gets the same result—so that the corresponding multiway graph leads to just a single final state:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092623result7img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092623result7img1.png' alt='' title='' width='204' height='209'> </div>\n</p></div>\n<p>But it’s not always true that there’s a single final state.

In some ways this is like the example above where we had two distinct rules: <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092623result7img18.png' width= '37' height='9' align='absmiddle'></span> and <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092623result7img19.png' width= '39' height='9' align='absmiddle'></span>. But there’s a difference. While explicit rules are essentially applied only “instantaneously”, an assignment like <em>x</em> = 1 has a “permanent” effect, at least until it is “overwritten” by another assignment. In an evaluation graph like the one above we’re showing particular expressions generated during the evaluation process. But when there are assignments, there’s an additional “hidden state” that in the Wolfram Language one can think of as corresponding to the state of the global symbol table. If we included this, then we’d again see rules that apply “instantaneously”, and we’d be able to explicitly trace causal dependencies between events. But if we elide it, then we effectively hide the causal dependence that’s “carried” by the state of the symbol table, and the evaluation graphs we’ve been drawing are necessarily somewhat incomplete.</p>\n<h2 id=\"computations-that-never-end\">Computations That Never End</h2>\n<p>The basic operation of the Wolfram Language evaluator is to keep doing transformations until the result no longer changes (or, in other words, until a fixed point is reached). And that’s convenient for being able to “get a definite answer”. But it’s rather different from what one usually imagines happens in physics. Because in that case we’re typically dealing with things that just “keep progressing through time”, without ever getting to any fixed point.

More elaborate recursive definitions can’t, however, readily be thought of as setting up straightforward self-referential data structures. But they still seem able to be characterized by transfinite numbers. </p>\n<p>In general many multiway graphs that differ in detail will be associated with a given transfinite number. But the expectation is that transfinite numbers can potentially provide robust characterizations of infinite evaluation processes, with different constructions of the “same evaluation” able to be identified as being associated with the same canonical transfinite number. </p>\n<p>Most likely, definitions purely involving pattern matching won’t be able to generate infinite evaluations beyond &#949;<sub>0</sub> = ω<sup>ω<sup>ω<sup>.<sup>.<sup>.</sup></sup></sup></sup></sup>—which is also the limit of where one can reach with proofs based on ordinary induction, Peano Arithmetic, etc. It’s <a href=\"https://www.wolframscience.com/nks/notes-12-9--examples-of-unprovable-statements/\">perfectly possible to go further</a>—but one needs to explicitly use functions like <tt><a href=\"http://reference.wolfram.com/language/ref/NestWhile.html\">NestWhile</a></tt> etc. in the definitions that are given.</p>\n<p>And there’s another issue as well: given a particular set of definitions, there’s no limit to how difficult it can be to determine the ultimate multiway graph that’ll be produced. In the end this is a consequence of computational irreducibility, and of the undecidability of the halting problem, etc. And what one can expect in the end is that some infinite evaluation processes one will be able to prove can be characterized by particular transfinite numbers, but others one won’t be able to “tie down” in this way—and in general, as computational irreducibility might suggest, won’t ever allow one to give a “finite symbolic summary”. </p>\n<h2 id=\"the-question-of-the-observer\">The Question of the Observer</h2>\n<p>One of the key lessons of our Physics Project is the importance of the character of the observer in determining what one “takes away” from a given underlying system. And in setting up the evaluation process—say in the Wolfram Language—the typical objective is to align with the way human observers expect to operate. And so, for example, one normally expects that one will give an expression as input, then in the end get an expression as output. The process of transforming input to output is analogous to the doing of a calculation, the answering of a question, the making of a decision, the forming of a response in human dialog, and potentially the forming of a thought in our minds. In all of these cases, we treat there as being a certain “static” output.</p>\n<p>It’s very different from the way physics operates, because in physics “time always goes on”: there’s (essentially) always another step of computation to be done. In our usual description of evaluation, we talk about “reaching a fixed point”. But an alternative would be to say that we reach a state that just repeats unchanged forever—but we as observers equivalence all those repeats, and think of it as having reached a single, unchanging state. </p>\n<p>Any modern practical computer also fundamentally works much more like physics: there are always computational operations going on—even though those operations may end up, say, continually putting the exact same pixel in the same place on the screen, so that we can “summarize” what’s going on by saying that we’ve reached a fixed point.</p>\n<p>There’s much that can be done with computations that reach fixed points, or, equivalently with functions that return definite values. And in particular it’s straightforward to compose such computations or functions, continually taking output and then feeding it in as input. But there’s a whole world of other possibilities that open up once one can deal with infinite computations. As a practical matter, one can treat such computations “lazily”—representing them as purely symbolic objects from which one can derive particular results if one explicitly asks to do so.</p>\n<p>One kind of result might be of the type typical in <a href=\"https://www.wolframscience.com/metamathematics/relations-to-automated-theorem-proving/\">logic programming or automated theorem proving</a>: given a potentially infinite computation, is it ever possible to reach a specified state (and, if so, what is the path to do so)? Another type of result might involve extracting a particular “time slice” (with some choice of foliation), and in general representing the result as a <tt>Multi</tt>. And still another type of result (reminiscent of “probabilistic programming”) might involve not giving an explicit <tt>Multi</tt>, but rather computing certain statistics about it.</p>\n<p>And in a sense, each of these different kinds of results can be thought of as what’s extracted by a different kind of observer, who is making different kinds of equivalences. </p>\n<p>We have a certain typical experience of the physical world that’s determined by features of us as observers. For example, as we mentioned above, we tend to think of “all of space” progressing “together” through successive moments of time. And the reason we think this is that the regions of space we typically see around us are small enough that the speed of light delivers information on them to us in a time that’s short compared to our “brain processing time”. If we were bigger or faster, then we wouldn’t be able to think of what’s happening in all of space as being “simultaneous” and we’d immediately be thrust into issues of relativity, reference frames, etc. </p>\n<p>And in the case of expression evaluation, it’s very much the same kind of thing. If we have an expression laid out in computer memory (or across a network of computers), then there’ll be a certain time to “collect information spatially from across the expression”, and a certain time that can be attributed to each update event. And the essence of array programming (and much of the operation of GPUs) is that one can assume—like in the typical human experience of physical space—that “all of space” is being updated “together”. </p>\n<p>But in our analysis above, we haven’t assumed this, and instead we’ve drawn causal graphs that explicitly trace dependencies between events, and show which events can be considered to be spacelike separated, so that they can be treated as “simultaneous”. </p>\n<p>We’ve also seen branchlike separation. In the physics case, the <a href=\"https://writings.stephenwolfram.com/2022/03/on-the-concept-of-motion/#motion-beyond-physical-space:-the-branchial-case\">assumption is that we as observers sample in an aggregated way across extended regions in branchial space</a>—just as we do across extended regions in physical space. And indeed the expectation is that we encounter what we describe as “quantum effects” precisely because we are of limited extent in branchial space. </p>\n<p>In the case of expression evaluation, we’re not used to being extended in branchial space. We typically imagine that we’ll follow some particular evaluation path (say, as defined by the standard Wolfram Language evaluator), and be oblivious to other paths. But, for example, strategies like speculative execution (typically applied at the hardware level) can be thought of as representing extension in branchial space.</p>\n<p>And at a theoretical level, one certainly thinks of different kinds of “observations” in branchial space. In particular, there’s nondeterministic computation, in which one tries to identify a particular “thread of history” that reaches a given state, or a state with some property one wants. </p>\n<p>One crucial feature of observers like us is that we are computationally bounded—which puts limitations on the kinds of observations we can make. And for example computational irreducibility then limits what we can immediately know (and aggregate) about the evolution of systems through time. And similarly multicomputational irreducibility limits what we can immediately know (and aggregate) about how systems behave across branchial space. And insofar as any computational devices we build in practice must be ones that we as observers can deal with, it’s inevitable that they’ll be subject to these kinds of limitations. (And, yes, in talking about quantum computers there tends to be an implicit assumption that we can in effect overcome multicomputational irreducibility, and “knit together” all the different computational paths of history—but it seems implausible that observers like us can actually do this, or can in general derive definite results without expending computationally irreducible effort.) </p>\n<p>One further small comment about observers concerns what in physics are called <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-in-our-models/foliations-of-causal-graphs/#p-346\" target=\"_blank\" rel=\"noopener\">closed timelike curves</a>—essentially loops in time. Consider the definition:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723observer10Aimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092623observer10img2.png' alt='' title='' width='146' height='14'> </div>\n</p></div>\n<p>This gives for example the multiway graph:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092623observer10img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092623observer10img3.png' alt='' title='' width='186' height='31'> </div>\n</p></div>\n<p>One can think of this as connecting the future to the past—something that’s sometimes interpreted as “allowing time travel”. But really this is just a more (time-)distributed version of a fixed point. In a fixed point, a single state is constantly repeated. Here a sequence of states (just two in the example given here) get visited repeatedly. The observer could treat these states as continually repeating in a cycle, or could coarse grain and conclude that “nothing perceptible is changing”. </p>\n<p>In spacetime we think of observers as making particular choices of simultaneity surfaces—or in effect picking particular ways to “parse” the causal graph of events. In branchtime the analog of this is that observers pick how to parse the multiway graph. Or, put another way, observers get to choose a path through the multiway graph, corresponding to a particular evaluation order or evaluation scheme. In general, there is a tradeoff between the choices made by the observer, and the behavior generated by applying the rules of the system.</p>\n<p>But if the observer is computationally bounded, they cannot overcome the computational irreducibility—or multicomputational irreducibility—of the behavior of the system. And as a result, if there is complexity in the detailed behavior of the system, the observer will not be able to avoid it at a detailed level by the choices they make. Though a critical idea of our Physics Project is that by appropriate aggregation, the observer will detect certain aggregate features of the system, that have robust characteristics independent of the underlying details. In physics, this represents a bulk theory suitable for the perception of the universe by observers like us. And presumably there is an analog of this in expression evaluation. But insofar as we’re only looking at the evaluation of expressions we’ve engineered for particular computational purposes, we’re not yet used to seeing “generic bulk expression evaluation”. </p>\n<p>But this is exactly what we’ll see if we just <a href=\"https://www.wolframscience.com/nks/\">go out and run &#8220;arbitrary programs&#8221;</a>, say found by enumerating certain classes of programs (like combinators or <a href=\"https://www.wolframphysics.org/bulletins/2021/02/multiway-turing-machines/\" target=\"_blank\" rel=\"noopener\">multiway Turing machines</a>). And for observers like us these will inevitably “seem very much like physics”.</p>\n<h2 id=\"the-tree-structure-of-expressions\">The Tree Structure of Expressions</h2>\n<p>Although we haven’t talked about this so far, any expression fundamentally <a href=\"https://reference.wolfram.com/language/ref/TreeForm.html\">has a tree structure</a>. So, for example, (1 + (2 + 2)) + (3 + 4) is represented—say internally in the Wolfram Language—as the tree:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092623tree11img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092623tree11img1.png' alt='' title='' width='235' height='172'> </div>\n</p></div>\n<p>So how does this tree structure interact with the process of evaluation? In practice it means for example that in the standard Wolfram Language evaluator there are two different kinds of recursion going on. The first is the progressive (“timelike”) reevaluation of subexpressions that change during evaluation. And the second is the (“spacelike” or “treelike”) scanning of the tree. </p>\n<p>In what we’ve discussed above, we’ve focused on evaluation events and their relationships, and in doing so we’ve concentrated on the first kind of recursion—and indeed we’ve often elided some of the effects of the second kind by, for example, immediately showing the result of evaluating <tt><a href=\"http://reference.wolfram.com/language/ref/Plus.html\">Plus</a></tt><tt>[2, 2]</tt> without showing more details of how this happens.</p>\n<p>But here now is a more complete representation of what’s going on in evaluating this simple expression:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092623tree11img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092623tree11img2.png' alt='' title='' width='359' height='348'> </div>\n</p></div>\n<p>The solid gray lines in this “<a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/TraceGraph\">trace graph</a>” indicate the subparts of the expression tree at each step.

But treelike-separated events affect nested parts of an expression (i.e. ones that appear on a single branch in the expression tree).

But in almost all uses of expressions—say in Wolfram Language—we end up needing to have hierarchical structure. </p>\n<p>If we were only doing single-way evaluation the hierarchical structure of expressions would be important in determining the order of evaluation to be used, but it wouldn’t immediately enmesh with core features of the evaluation process. But in multiway evaluation “higher” treelike-separated events can in effect cut off the evaluation histories of “lower” ones—and so it’s inevitably central to the evaluation process. For spacelike- and branchlike-separated events, we can always choose different reference frames (or different spacelike or branchlike surfaces) that arrange the events differently. But treelike-separated events—a little like timelike-separated ones—have a certain forced relationship that cannot be affected by an observer’s choices.</p>\n<h2 id=\"grinding-everything-down-to-hypergraphs\">Grinding Everything Down to Hypergraphs</h2>\n<p>To draw causal graphs—and in fact to do a lot of what we’ve done here—we need to know “what depends on what”. And with our normal setup for expressions this can be quite subtle and complicated. We apply the rule <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092623grinding11img1.png' width= '114' height='15' align='absmiddle'></span> to <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092623grinding11img2.png' width= '37' height='15' align='absmiddle'></span> to give the result <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092623grinding11img3.png' width= '35' height='15' align='absmiddle'></span>. But does the a that “comes out” depend on the a that went in, or is it somehow something that’s “independently generated”? Or, more extremely, in a transformation like <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092623grinding11img4.png' width= '130' height='12' align='absmiddle'></span>, to what extent is it “the same 1” that goes in and comes out? And how do these issues of dependence work when there are the kinds of treelike relations discussed in the previous section?</p>\n<p>The Wolfram Language evaluator defines how expressions should be evaluated—but doesn’t immediately specify anything about dependencies. Often we can look “after the fact” and deduce what “was involved” and what was not—and thus what should be considered to depend on what. But it’s not uncommon for it to be hard to know what to say—forcing one to make what seem likely arbitrary decisions. So is there any way to avoid this, and to set things up so that dependency becomes somehow “obvious”? </p>\n<p>It turns out that there is—though, perhaps not surprisingly, it comes with difficulties of its own. But the basic idea is to go “below expressions”, and to “grind everything down” to hypergraphs whose nodes are ultimate direct “carriers” of identity and dependency. It’s all deeply reminiscent of our Physics Project—and its <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">generalization in the ruliad</a>.

The rule operates on collections of hyperedges, always consuming 3 hyperedges, and generating 1. We can think of the hyperedges as “fundamental tokens”.

Thus, for example, in the representation of the string, the infrastructure emes define the pointer structure for a linked list—with the content emes being the “payloads” (and pointing to globally shared locations, like ones for A and B). </p>\n<p>Transformations obtained by applying rules can then be thought of as corresponding just to rearranging pointers. Sometimes “new emes” have to be created, corresponding to new memory being allocated. We don’t have an explicit way to “free” memory. But sometimes some part of the hypergraph will become disconnected—and one can then imagine disconnected pieces to which the observer is not attached being garbage collected.</p>\n<h2 id=\"the-rulial-case\">The Rulial Case</h2>\n<p>So far we’ve discussed what happens in the evaluation of particular expressions according to particular rules (where those rules could just be all the ones that are built into Wolfram Language).

But if we consider rulial multiway evaluation, we’d have branches for each of these definitions.</p>\n<p>In what we’ve discussed before, we effectively allow evaluation to take infinite time, as well as infinite space and infinite branchial space. But now we’ve got the new concept of infinite rulial space. We might say from the outset that, for example, we’re going to use all possible rules. Or we might have what amounts to a dynamical process that generates possible rules. </p>\n<p>And the key point is that as soon as that process is in effect computation universal, there is a way to translate from one instance of it to another. Different specific choices will lead to a different basis—but in the end they’ll all eventually generate the full ruliad. </p>\n<p>And actually, this is where the whole concept of expression evaluation ultimately merges with fundamental physics. Because in both cases, the limit of what we’re doing will be exactly the same: the full ruliad.</p>\n<h2 id=\"the-practical-computing-story\">The Practical Computing Story</h2>\n<p>The formalism we’ve discussed here—and particularly its correspondence with fundamental physics—is in many ways a new story. But it has precursors that go back more than a century. And indeed as soon as industrial processes—and production lines—began to be formalized, it became important to understand interdependencies between different parts of a process. By the <a href=\"https://www.wolframscience.com/nks/notes-9-9--causal-networks/\">1920s flowcharts had been invented</a>, and when digital computers were developed in the 1940s they began to be used to represent the “flow” of programs (and in fact <a href=\"https://writings.stephenwolfram.com/2015/12/untangling-the-tale-of-ada-lovelace/#babbage%E2%80%99s-secret-sauce\">Babbage had used something similar</a> even in the 1840s). At first, at least as far as programming was concerned, it was all about the “flow of control”—and the sequence in which things should be done. But by the 1970s the notion of the “flow of data” was also widespread—in some ways reflecting back to actual flow of electrical signals. In some simple cases various forms of “visual programming”—typically based on connecting virtual wires—have been popular. And even in modern times, it’s not uncommon to talk about “<a href=\"https://reference.wolfram.com/language/ref/NetGraph.html\">computation graphs</a>” as a way to specify how data should be routed in a computation, for example in sequences of operations on tensors (say for neural net applications).</p>\n<p>A different tradition—originating in mathematics in the late 1800s—involved the routine use of “abstract functions” like <em>f</em>(<em>x</em>). Such abstract functions could be used both “symbolically” to represent things, and explicitly to “compute” things. All sorts of (often ornate) formalism was developed in mathematical logic, with <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-and-the-story-of-computation/\">combinators arriving in 1920</a>, and lambda calculus in 1935. By the late 1950s <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-and-the-story-of-computation/#practical-computation\">there was LISP</a>, and by the 1970s there was a definite tradition of “functional programming” involving the processing of things by successive application of different functions. </p>\n<p>The question of what really depended on what became more significant whenever there was the possibility of doing computations in parallel. This was already being discussed in the 1960s, but became more popular in the early 1980s, and in a sense finally “went mainstream” with GPUs in the 2010s. And indeed our discussion of causal graphs and spacelike separation isn’t far away from the kind of thing that’s often discussed in the context of designing parallel algorithms and hardware. But one difference is that in those cases one’s usually imagining having a “static” flow of data and control, whereas here we’re routinely considering causal graphs, etc. that are being created “on the fly” by the actual progress of a computation.</p>\n<p>In many situations—with both algorithms and hardware—one has precise control over when different “events” will occur. But in distributed systems it’s also common for events to be asynchronous. And in such cases, it’s possible to have “conflicts”, “race conditions”, etc. that correspond to branchlike separation. There have been various attempts—many originating in the 1970s—to develop formal “process calculi” to describe such systems. And in some ways what we’re doing here can be seen as a physics-inspired way to clarify and extend these kinds of approaches. </p>\n<p>The concept of <a href=\"https://www.wolframscience.com/nksonline/page-938b/\">multiway systems also has a long history</a>—notably appearing in the early 1900s in connection with game graphs, formal group theory and various problems in combinatorics. Later, multiway systems would implicitly show up in considerations of automated theorem proving and nondeterministic computation. In practical microprocessors it’s been common for a decade or so to do “speculative execution” where multiple branches in code are preemptively followed, keeping only the one that’s relevant given actual input received.</p>\n<p>And when it comes to branchlike separation, a notable practical example arises in version control and collaborative editing systems. If a piece of text has changes at two separated places (“spacelike separation”), then these changes (“diffs”) can be applied in any order. But if these changes involve the same content (e.g. same characters) then there can be a conflict (“merge conflict”) if one tries to apply the changes—in effect reflecting the fact that these changes were made by branchlike-separated “change events” (and to trace them requires creating different “forks” or what we might call different histories).</p>\n<p>It’s perhaps worth mentioning that as soon as one has the concept of an “expression” one is led to the concept of “evaluation”—and as we’ve seen many times here, that’s even true for arithmetic expressions, like 1 + (2 + 3). We’ve been particularly concerned with questions about “what depends on what” in the process of evaluation. But in practice there’s often also the question of when evaluation happens. The Wolfram Language, for example, distinguishes between “<a href=\"https://reference.wolfram.com/language/ref/Set.html\">immediate evaluation</a>” done when a definition is made, and “<a href=\"https://reference.wolfram.com/language/ref/SetDelayed.html\">delayed evaluation</a>” done when it’s used. There’s also lazy evaluation where what’s immediately generated is a symbolic representation of the computation to be done—with steps or pieces being explicitly computed only later, when they are requested. </p>\n<p>But what really is “<a href=\"https://reference.wolfram.com/language/tutorial/EvaluationOfExpressions.html\">evaluation</a>”? If our “input expression” is 1 + 1, we typically think of this as “defining a computation that can be done”. Then the idea of the “process of evaluation” is that it does that computation, deriving a final “value”, here 2. And one view of the Wolfram Language is that its whole goal is to set up a collection of transformations that do as many computations that we know how to do as possible. Some of those transformations effectively incorporate “factual knowledge” (like knowledge of mathematics, or chemistry, or geography). But some are more abstract, like transformations defining how to do transformations, say on patterns. </p>\n<p>These abstract transformations are in a sense the easiest to trace—and often above that’s what we’ve concentrated on. But usually we’ve allowed ourselves to do at least some transformations—like adding numbers—that are built into the “insides” of the Wolfram Language. It’s perhaps worth mentioning that in conveniently representing such a broad range of computational processes the Wolfram Language ends up having some <a href=\"https://reference.wolfram.com/language/tutorial/EvaluationOfExpressions.html\">quite elaborate evaluation mechanisms</a>. A common example is the idea of functions that “hold their arguments”, evaluating them only as “specifically requested” by the innards of the function. Another—that in effect creates a “side chain” to causal graphs—are conditions (e.g. <a href=\"https://reference.wolfram.com/language/ref/Condition.html\">associated with <tt>/;</tt></a>) that need to be evaluated to determine whether patterns are supposed to match. </p>\n<p>Evaluation is in a sense the central operation in the Wolfram Language. And what we’ve seen here is that it has a deep correspondence with what we can view as the “central operation” of physics: the passage of time. Thinking in terms of physics helps organize our thinking about the process of evaluation—and it also suggests some important generalizations, like multiway evaluation. And one of the challenges for the future is to see how to take such generalizations and “package” them as part of our computational language in a form that we humans can readily understand and make use of.</p>\n<h2 id=\"some-personal-history:-recursion-control-in-smp\">Some Personal History: Recursion Control in SMP</h2>\n<p>It was in late 1979 that I first started to <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">design my SMP (&#8220;Symbolic Manipulation Program&#8221;) system</a>.

If you set <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img1.png' width= '37' height='11' align='absmiddle'></span>, then you set <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img2.png' width= '35' height='11' align='absmiddle'></span>, you should get <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img3.png' width= '7' height='8' align='absmiddle'></span> (not <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img4.png' width= '9' height='11' align='absmiddle'></span>) if you asked for <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img5.png' width= '8' height='8' align='absmiddle'></span>. It’s what most people would expect should happen. But like almost all fundamental design decisions, in addition to its many benefits, it had some unexpected consequences. For example, it meant that if you set <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img6.png' width= '60' height='9' align='absmiddle'></span> without having given a value for <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img7.png' width= '8' height='8' align='absmiddle'></span>, you’d in principle get an infinite loop.</p>\n<p>Back in 1980 there were computer scientists who asserted that this meant the “infinite evaluation” I’d built into the core of SMP “could never work”. Four decades of experience tells us rather definitively that in practice they were wrong about this (essentially because people just don’t end up “falling into the <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img8.png' width= '60' height='9' align='absmiddle'></span> pothole” when they’re doing actual computations they want to do). But questions like those around <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img9.png' width= '60' height='9' align='absmiddle'></span> made me particularly aware of issues around recursive evaluation. And it bothered me that a recursive factorial definition like <tt>f[n_]:=n f[n–1]</tt> (the rather less elegant SMP notation was <span class=\"computer-voice\">f[$n]::$n f[$1-1]</span>) might just run infinitely if it didn’t have a base case (<span class=\"computer-voice\">f[1] = 1</span>), rather than terminating with the value 0, which it “obviously should have”, given that at some point one’s computing 0×&#8230;.</p>\n<p>So in SMP I invented a rather elaborate scheme for recursion control that “solved” this problem. And here’s what happens in SMP (now running on a reconstructed virtual machine):</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img11_v2.png' alt='SMP code' title='SMP code' width='592' height=''/></p>\n<p>And, yes, if one includes the usual base case for factorial, one gets the usual answer:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img13_v2.png' alt='SMP code' title='SMP code' width='592' height=''/></p>\n<p>So what is going on here? Section 3.1 of the SMP documentation in principle tells the story. In SMP I used the term “simplification” for what I’d now call “evaluation”, both because I imagined that most transformations one wanted would make things “simpler” (as in <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img14.png' width= '61' height='9' align='absmiddle'></span>), and because there was a nice pun between the name SMP and the function <span class=\"computer-voice\">Smp</span> that carried out the core operation of the system (yes, SMP rather foolishly used short names for built-in functions). Also, it’s useful to know that in SMP I called an ordinary expression like <span class=\"computer-voice\">f[x, y, &#8230;]</span> a “projection”: its “head” <span class=\"computer-voice\">f</span> was called its “projector”, and its arguments <span class=\"computer-voice\">x, y</span>, &#8230; were called “filters”.</p>\n<p>As the <a href=\"https://files.wolframcdn.com/pub/www.stephenwolfram.com/pdf/smp-manual.pdf\" target=\"_blank\" rel=\"noopener\">Version 1.0 documentation from July 1981</a> tells it, “simplification” proceeds like this:</p>\n<p><a class='magnific image' alt='' title='' href='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img17.png'><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img17.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='374'/></a></p>\n<p>By the next year, <a href=\"https://content.wolfram.com/sw-publications/2020/07/smp-summary.pdf\">it was a bit more sophisticated</a>, though the default behavior didn’t change:</p>\n<p><a class='magnific image' alt='' title='' href='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img20.png'><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img20.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='497'/></a></p>\n<p>With the definitions above, the value of <span class=\"computer-voice\">f</span> itself was (compare <tt><a href=\"http://reference.wolfram.com/language/ref/Association.html\">Association</a></tt> in Wolfram Language):</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img22_v2.png' alt='SMP code' title='SMP code' width='592' height=''/></p>\n<p>But the key to evaluation without the base case actually came in the “properties” of multiplication:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img24_v2.png' alt='SMP code' title='SMP code' width='592' height=''/></p>\n<p>In SMP <span class=\"computer-voice\">True</span> was (foolishly) 1. It’s notable here that <span class=\"computer-voice\">Flat</span> corresponds to the attribute <tt><a href=\"http://reference.wolfram.com/language/ref/Flat.html\">Flat</a></tt> in Wolfram Language, <span class=\"computer-voice\">Comm</span> to <tt><a href=\"http://reference.wolfram.com/language/ref/Orderless.html\">Orderless</a></tt> and <span class=\"computer-voice\">Ldist</span> to <tt><a href=\"http://reference.wolfram.com/language/ref/Listable.html\">Listable</a></tt>. (<span class=\"computer-voice\">Sys</span> indicated that this was a built-in system function, while <span class=\"computer-voice\">Tier</span> dealt with weird consequences of the attempted unification of arrays and functions into an association-like construct.) But the critical property here was <span class=\"computer-voice\">Smp</span>. By default its value was <span class=\"computer-voice\">Inf</span> (for <a href=\"https://reference.wolfram.com/language/ref/Infinity.html\"><tt>Infinity</tt></a>). But for <span class=\"computer-voice\">Mult</span> (<a href=\"https://reference.wolfram.com/language/ref/Times.html\"><tt>Times</tt></a>) it was 1. </p>\n<p>And what this did was to tell the SMP evaluator that inside any multiplication, it should allow a function (like <span class=\"computer-voice\">f</span>) to be called recursively at most once before the actual multiplication was done. Telling SMP to trace the evaluation of <span class=\"computer-voice\">f[5]</span> we then see:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img26_v2.png' alt='SMP code' title='SMP code' width='592' height=''/></p>\n<p>So what’s going on here? The first time <span class=\"computer-voice\">f</span> appears inside a multiplication its definition is used. But when <span class=\"computer-voice\">f</span> appears recursively a second time, it’s effectively frozen—and the multiplication is done using its frozen form, with the result that as soon as a 0 appears, one just ends up with 0.</p>\n<p>Reset the <span class=\"computer-voice\">Smp</span> property of <span class=\"computer-voice\">Mult</span> to infinity, and the evaluation runs away, eventually producing a rather indecorous crash:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img29_v2.png' alt='SMP code' title='SMP code' width='592' height='547'/></p>\n<p>In effect, the <span class=\"computer-voice\">Smp</span> property defines how many recursive evaluations of arguments should be done before a function itself is evaluated. Setting the <span class=\"computer-voice\">Smp</span> property to 0 has essentially the same effect as the <tt><a href=\"http://reference.wolfram.com/language/ref/HoldAll.html\">HoldAll</a></tt> attribute in Wolfram Language: it prevents arguments from being evaluated until a function as a whole is evaluated. Setting <span class=\"computer-voice\">Smp</span> to value <em>k</em> basically tells SMP to do only <em>k</em> levels of “depth-first” evaluation before collecting everything together to do a “breadth-first evaluation”.</p>\n<p>Let’s look at this for a recursive definition of Fibonacci numbers:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img31_v2.png' alt='SMP code' title='SMP code' width='592' height=''/></p>\n<p>With the <span class=\"computer-voice\">Smp</span> property of <span class=\"computer-voice\">Plus</span> set to infinity, the sequence of evaluations of <span class=\"computer-voice\">f</span> follows a pure “depth-first” pattern</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img33_v2.png' alt='SMP code' title='SMP code' width='620' height=''/></p>\n<p>where we can plot the sequence of <tt>f[</tt><em>n</em><tt>]</tt> evaluated as:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img34_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img34-v2.png' alt='' title='' width='666' height='187'> </div>\n</p></div>\n<p>But with the default setting of 1 for the <span class=\"computer-voice\">Smp</span> property of <span class=\"computer-voice\">Plus</span> the sequence is different</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img36_v2.png' alt='SMP code' title='SMP code' width='620' height='683'/></p>\n<p>and now the sequence of <tt>f[</tt><em>n</em><tt>]</tt> evaluated is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img37_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img37-v2.png' alt='' title='' width='666' height='187'> </div>\n</p></div>\n<p>In the pure depth-first case all the exponentially many leaves of the Fibonacci tree are explicitly evaluated. But now the evaluation of <span class=\"computer-voice\">f[</span><em>n</em><span class=\"computer-voice\">]</span> is being frozen after each step and terms are being collected and combined. Starting for example from <span class=\"computer-voice\">f[10]</span> we get <span class=\"computer-voice\">f[9]</span>&hairsp;<span class=\"computer-voice\">+</span>&hairsp;<span class=\"computer-voice\">f[8]</span>. And evaluating another step we get <nobr><span class=\"computer-voice\">f[8]</span>&hairsp;<span class=\"computer-voice\">+</span>&hairsp;<span class=\"computer-voice\">f[7]</span>&hairsp;<span class=\"computer-voice\">+</span>&hairsp;<span class=\"computer-voice\">f[7]</span>&hairsp;<span class=\"computer-voice\">+</span>&hairsp;<span class=\"computer-voice\">f[6]</span></nobr>. But now the <span class=\"computer-voice\">f[7]</span>’s can be combined into <nobr><span class=\"computer-voice\">f[8]</span>&hairsp;<span class=\"computer-voice\">+</span>&hairsp;<span class=\"computer-voice\">2f[7]</span>&hairsp;<span class=\"computer-voice\">+</span>&hairsp;<span class=\"computer-voice\">f[6]</span></nobr> so that they don’t both have to separately be evaluated. And in the end only quadratically many separate evaluations are needed to get the final result.</p>\n<p>I don’t now remember quite why I put it in, but SMP also had another piece of recursion control: the <span class=\"computer-voice\">Rec</span> property of a symbol—which basically meant “it’s OK for this symbol to appear recursively; don’t count it when you’re trying to work out whether to freeze an evaluation”. </p>\n<p>And it’s worth mentioning that SMP also had a way to handle the original <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img38.png' width= '60' height='9' align='absmiddle'></span> issue:</p>\n<p><a class='magnific image' alt='' title='' href='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img40.png'><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img40.png' alt='Click to enlarge' title='Click to enlarge' width='548' height='71'/></a></p>\n<p>It wasn’t a terribly general mechanism, but at least it worked in this case:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723recursion15img42_v2.png' alt='SMP code' title='SMP code' width='592' height=''/></p>\n<p>I always thought that SMP’s “wait and combine terms before recursing” behavior was quite clever, but beyond the factorial and Fibonacci examples here I’m not sure I ever found clear uses for it. Still, with our current physics-inspired way of looking at things, we can see that this behavior basically corresponded to picking a “more spacetime-like” foliation of the evaluation graph.</p>\n<p>And it’s a piece of personal irony that right around the time I was trying to figure out recursive evaluation in SMP, I was also <a href=\"https://www.stephenwolfram.com/publications/academic/particle-physics/\">working on gauge theories in physics</a>—which in the end involve very much the same kinds of issues. But it took another four decades—and the development of our Physics Project—before I saw the fundamental connection between these things.</p>\n<h2 id=\"after-smp:-further-personal-history\">After SMP: Further Personal History</h2>\n<p>The idea of parallel computation was one that I was already thinking about at the very beginning of the 1980s—partly at a theoretical level for things like neural nets and cellular automata, and partly at a practical level for SMP (and indeed by 1982 I had described a <span class=\"computer-voice\">Ser</span> property in SMP that was supposed to ensure that the arguments of a particular function would always get evaluated in a definite order “in series”). Then in 1984 I was involved in trying to design a <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">general language for parallel computation on the Connection Machine</a> “massively parallel” computer. The “obvious” approach was just to assume that programs would be set up to operate in steps, even if at each step many different operations might happen in parallel. But I somehow thought that there must be a better approach, somehow based on graphs, and graph rewriting. But back then I didn’t, for example, think of formulating things in terms of causal graphs. And while I knew about phenomena like race conditions, I hadn’t yet internalized the idea of constructing multiway graphs to “represent all possibilities”. </p>\n<p>When I started designing Mathematica—and what’s now the Wolfram Language—in 1986, I used the same core idea of transformation rules for symbolic expressions that was the basis for SMP. But I was able to greatly streamline the way expressions and their evaluation worked. And not knowing compelling use cases, I decided not to set up the kind of elaborate recursion control that was in SMP, and instead just to concentrate on basically two cases: functions with ordinary (essentially leftmost-innermost) evaluation and functions with held-argument (essentially outermost) evaluation. And I have to say that in three decades of usages and practical applications I haven’t really missed having more elaborate recursion controls.</p>\n<p>In working on <em><a href=\"https://www.wolframscience.com/nks/\">A New Kind of Science</a></em> in the 1990s, issues of evaluation order <a href=\"https://www.wolframscience.com/nks/notes-3-10--order-dependence-in-symbolic-systems/\">first came up</a> in connection with “symbolic systems” (essentially, generalized combinators). They then came up more poignantly when I explored the possible computational “infrastructure” for spacetime—and indeed that was <a href=\"https://www.wolframscience.com/nks/chap-9--fundamental-physics#sect-9-9--time-and-causal-networks\">where I first started explicitly discussing and constructing causal graphs</a>. </p>\n<p>But it was not until 2019 and early 2020, with the development of our Physics Project, that clear concepts of spacelike and branchlike separation for events emerged. The correspondence with expression evaluation got clearer in December 2020 when—in connection with the <a href=\"https://writings.stephenwolfram.com/2020/12/where-did-combinators-come-from-hunting-the-story-of-moses-schonfinkel/\">centenary of their invention</a>—I did an <a href=\"https://writings.stephenwolfram.com/2020/12/combinators-a-centennial-view/\">extensive investigation of combinators</a> (leading to my book <em><a href=\"https://www.wolfram-media.com/products/combinators-a-centennial-view/\">Combinators</a></em>). And as I started to explore the <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/\">general concept of multicomputation</a>, and its many potential applications, I soon saw the need for systematic ways to think about multicomputational evaluation in the context of symbolic language and symbolic expressions. </p>\n<p>In both SMP and Wolfram Language the main idea is to “get results”. But particularly for debugging it’s always been of interest to see some kind of trace of how the results are obtained. In SMP—as we saw above—there was a <span class=\"computer-voice\">Trace</span> property that would cause any evaluation associated with a particular symbol to be printed. But what about an actual computable representation of the “trace”? In 1990 we introduced the function <tt><a href=\"http://reference.wolfram.com/language/ref/Trace.html\">Trace</a></tt> in the Wolfram Language—which produces what amounts to a symbolic representation of an evaluation process. </p>\n<p>I had high hopes for <tt><a href=\"http://reference.wolfram.com/language/ref/Trace.html\">Trace</a></tt>—and for its ability to turn things like control flows into structures amenable to direct manipulation. But somehow what <tt><a href=\"http://reference.wolfram.com/language/ref/Trace.html\">Trace</a></tt> produces is almost always too difficult to understand in real cases. And for many years I kept the problem of “making a better <tt><a href=\"http://reference.wolfram.com/language/ref/Trace.html\">Trace</a></tt>” on my to-do list, though without much progress. </p>\n<p>The problem of “exposing a process of computation” is quite like the problem of presenting a proof. And in 2000 I had occasion to use automated theorem proving to <a href=\"https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/\">produce a long proof of my minimal axiom system for Boolean algebra</a>. We wanted to introduce such methods into Mathematica (or what’s now the Wolfram Language). But we were stuck on the question of how to represent proofs—and in 2007 we ended up integrating just the “answer” part of the methods into the function <tt><a href=\"http://reference.wolfram.com/language/ref/FullSimplify.html\">FullSimplify</a></tt>. </p>\n<p>By the 2010s we’d had the experience of producing step-by-step explanations in <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>, as well as exploring proofs in the context of <a href=\"https://writings.stephenwolfram.com/2014/08/computational-knowledge-and-the-future-of-pure-mathematics/\">representing pure-mathematical knowledge</a>. And finally in 2018 we introduced <tt><a href=\"http://reference.wolfram.com/language/ref/FindEquationalProof.html\">FindEquationalProof</a></tt>, which provided a symbolic representation of proofs—at least ones based on successive pattern matching and substitution—as well as a graphical representation of the relationships between lemmas.</p>\n<p>After the arrival of our Physics Project—as well as my exploration of combinators—I returned to questions about the foundations of mathematics and developed a whole “<a href=\"https://writings.stephenwolfram.com/2022/03/the-physicalization-of-metamathematics-and-its-implications-for-the-foundations-of-mathematics/\">physicalization of metamathematics</a>” based on tracing what amount to multiway networks of proofs. But the steps in these proofs were still in a sense purely structural, involving only pattern matching and substitution. </p>\n<p>I explored other applications of “multicomputation”, generating <a href=\"https://www.wolframphysics.org/bulletins/2021/10/multicomputation-with-numbers-the-case-of-simple-multiway-systems\" target=\"_blank\" rel=\"noopener\">multiway systems based on numbers</a>, <a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-multicomputational-systems/\">multiway systems representing games</a>, and so on. And I kept on wondering—and sometimes doing livestreamed discussions about—how best to create a language design around multicomputation. And as a first step towards that, we developed the <tt><a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/TraceGraph/\">TraceGraph</a></tt> function in the <a href=\"https://resources.wolframcloud.com/FunctionRepository/\">Wolfram Function Repository</a>, which finally provided a somewhat readable graphical rendering of the output of <tt><a href=\"http://reference.wolfram.com/language/ref/Trace.html\">Trace</a></tt><tt>—</tt>and began to show the causal dependencies in at least single-way computation. But what about the multiway case? For the Physics Project we’d already developed <tt><a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/MultiwaySystem\">MultiwaySystem</a></tt> and related functions in the Wolfram Function Repository. So now the question was: how could one streamline this and have it provide essentially a multiway generalization of <tt><a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/TraceGraph/\">TraceGraph</a></tt>? We began to think about—and implement—concepts like <tt>Multi</tt>, and imagine ways in which general multicomputation could encompass things like logic programming and probabilistic programming, as well as nondeterministic and quantum computation.</p>\n<p>But meanwhile, the “<span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/09/sw092723further16img1.png' width= '60' height='9' align='absmiddle'></span> question” that had launched my whole adventure in recursion control in SMP was still showing up—43 years later—in the Wolfram Language. It had been there since <a href=\"https://reference.wolfram.com/legacy/v1/\">Version 1.0</a>, though it never seemed to matter much, and we’d always handled it just by having a <a href=\"https://reference.wolfram.com/language/ref/$RecursionLimit.html\">global &#8220;recursion limit&#8221;</a>—and then “holding” all further subevaluations:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw040123img90A.png' alt='' title='' width='482' height=''> </p>\n<p>But over the years there’d been increasing evidence that this wasn’t quite adequate, and that for example further processing of the held form (even, for example, formatting it) could in extreme cases end up triggering even infinite cascades of evaluations. So finally—in <a href=\"https://writings.stephenwolfram.com/2022/12/the-latest-from-our-rd-pipeline-version-13-2-of-wolfram-language-mathematica\">Version 13.2</a> at the end of last year—we introduced the beginnings of a <a href=\"https://writings.stephenwolfram.com/2022/12/the-latest-from-our-rd-pipeline-version-13-2-of-wolfram-language-mathematica/#controlling-runaway-computations-\">new mechanism to cut off &#8220;runaway&#8221; computations</a>, based on a construct called <tt><a href=\"http://reference.wolfram.com/language/ref/TerminatedEvaluation.html\">TerminatedEvaluation</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/09/sw092723further16img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/09/sw092723further16img3.png' alt='' title='' width='342' height='72'> </div>\n</p></div>\n<p>And from the beginning we wanted to see how to encode within <tt><a href=\"http://reference.wolfram.com/language/ref/TerminatedEvaluation.html\">TerminatedEvaluation</a></tt> information about just what evaluation had been terminated. But to do this once again seemed to require having a way to represent the “ongoing process of evaluation”—leading us back to <tt><a href=\"http://reference.wolfram.com/language/ref/Trace.html\">Trace</a></tt>, and making us think about evaluation graphs, causal graphs, etc.</p>\n<p>At the beginning <em>x</em> = <em>x</em> + 1 might just have seemed like an irrelevant corner case—and for practical purposes it basically is. But already four decades ago it led me to start thinking not just about the results of computations, but also how their internal processes can be systematically organized. For years, I didn’t really connect this to my work on explicit computational processes like those in systems such as cellular automata. Hints of such connections did start to emerge as I began to try to build computational models of fundamental physics. But looking back I realize that in <em>x</em> = <em>x</em> + 1 there was already in a sense a shadow of what was to come in our Physics Project and in the whole construction of the ruliad. </p>\n<p>Because <em>x</em> = <em>x</em> + 1 is something which—like physics and like the ruliad—necessarily generates an ongoing process of computation. One might have thought that the fact that it doesn’t just “give an answer” was in a sense a sign of uselessness. But what we’ve now realized is that our whole existence and experience is based precisely on “living inside a computational process” (which, fortunately for us, hasn’t just “ended with an answer”). Expression evaluation is in its origins intended as a “human-accessible” form of computation. But what we’re now seeing is that its essence also inevitably encompasses computations that are at the core of fundamental physics. And by seeing the correspondence between what might at first appear to be utterly unrelated intellectual directions, we can expect to inform both of them. Which is what I have started to try to do here.</p>\n<h2 id=\"notes-&#038;-thanks\" style='font-size:1.2rem'>Notes &#038; Thanks</h2>\n<p style='font-size:90%'>What I&#8217;ve described here builds quite directly on some of my recent work, particularly as covered in my books <a href=\"https://www.wolfram-media.com/products/combinators-a-centennial-view/\"><em>Combinators: A Centennial View</em></a> and <a href=\"https://www.wolfram-media.com/products/metamathematics-foundations-and-physicalization/\"><em>Metamathematics: Physicalization &#038; Foundations</em></a>. But as I mentioned above, I started thinking about related issues at the beginning of the 1980s in connection with the design of SMP, and I&#8217;d like to thank members of the SMP development team for discussions at that time, particularly Chris Cole, Jeff Greif and Tim Shaw. Thanks also to Bruce Smith for his 1990 work on <a href=\"http://reference.wolfram.com/language/ref/Trace.html\"><tt>Trace</tt></a> in Wolfram Language, and for encouraging me to think about symbolic representations of computational processes. In much more recent times, I&#8217;d particularly like to thank Jonathan Gorard for his extensive conceptual and practical work on multiway systems and their formalism, both in our Physics Project and beyond. Some of the directions described here have (at least indirectly) been discussed in a number of recent <a href=\"https://livestreams.stephenwolfram.com/category/live-ceoing/\">Wolfram Language design review livestreams</a>, with particular participation by Ian Ford, Nik Murzin, and Christopher Wolfram, as well as Dan Lichtblau and Itai Seggev.

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/uploads/sites/34/2020/07/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 &#8216;sources of power&#8217; 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=''/></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;\">&#8230;</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-wolfram|alpha\">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&#8230;</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>&#8212; 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&#8230;</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!

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&#8217;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&#215;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,&#8230;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 &#8230;</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&#8217;s chat again at your convenience&#8230; it bothers both of us, I<br />\nbelieve, that our systems aren&#8217;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",

A long and colorful story. An elaborate description of a wild idea. In the forty years I knew <a href=\"https://www.wolframalpha.com/input?i=ed+fredkin\">Ed Fredkin</a> I heard countless wild ideas and colorful stories from him. He always radiated a certain adventurous joy—together with supreme, almost-childlike confidence. Ed was someone who wanted to independently figure things out for himself, and delighted in presenting his often somewhat-outlandish conclusions—whether about technology, science, business or the world—with dramatic showman-like panache.</p>\n<p>In all the years I knew Ed, I’m not sure he ever really listened to anything I said (though he did use <a href=\"https://www.wolfram.com/language/\">tools I built</a>). He used to like to tell people I’d learned a lot from him. And indeed we had intellectual interests that should have overlapped. But in actuality our ways of thinking about them mostly didn’t connect much at all. But at a personal and social level it was still always a lot of fun being around Ed and being exposed to his unique intense opportunistic energy—with its repeating themes but ever-changing directions.<span id=\"more-52991\"></span></p>\n<p>And there was one way in which Ed and I were very much aligned: both of our lives were deeply influenced by computers and computing. Ed had started with computers in 1956—as part of one of the very first cohorts of programmers. And perhaps on the basis of that experience, he would still, even at the end of his life, matter-of-factly refer to himself as “the world’s best programmer”. Indeed, so confident was he of his programming prowess that he became convinced that he should in effect be able to write a program for the universe—and make all of physics into a programming problem. It didn’t help that his knowledge of physics was at best spotty (and, for example, I don’t think he ever really learned calculus). But his almost lifelong desire to “program physics” did successfully lead him to the concept of reversible logic, and to what’s now called the “<a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/QuantumCircuitOperator/\">Fredkin gate</a>”. But it also led him to the idea that the universe must be a giant cellular automaton—whose program he could invent.</p>\n<p>I first met Ed in 1982—on an island in the Caribbean he had bought with money from taking public a tech company he’d founded. The year before, <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 had started studying cellular automata</a>, but, unlike Ed, I wasn’t trying to “program” them—to be the universe or anything else. Instead, I was mostly doing what amounted to empirical science, running computer experiments to see what they did, and treating them as part of a computational universe of possible programs “out there to explore”. It wasn’t a methodology I think Ed ever really understood—or cared about. He was a programmer (and inventor), not an empirical scientist. And he was convinced—like a modern analog of an ancient Greek philosopher—that by pure thought he could come up with the whole “clockwork” of the universe.</p>\n<p>Central to his picture was the idea that at the bottom of everything was a cellular automaton, with its grid of cells somehow laid out in space. I told Ed countless times that what was known from twentieth-century physics <a href=\"https://www.wolframscience.com/nks/chap-9--fundamental-physics#sect-9-6--the-nature-of-space\">implied this really couldn&#8217;t be</a> how things worked at a fundamental level. I tried to interest Ed in my way of using cellular automata. But Ed wasn’t interested. He was going for what he saw as the big prize: using them to “construct the universe”. </p>\n<p>Every few years Ed would tell me he’d made progress—and rather dramatically say things like that he’d “found the electron”. I’d politely ask for details. Then start pointing out that it couldn’t work that way. But soon Ed would be telling a story or talking about some completely different idea—about technology, business or something else. </p>\n<p>By the mid-1980s I’d discovered a lot about cellular automata. And I always <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\">felt a bit embarrassed</a> by Ed’s attempt to use them in what seemed to me like a very naive way for fundamental physics—and I worried (as did happen a few times) that people would dismiss my efforts by identifying them with his. </p>\n<p>My own career had begun in the 1970s with traditional fundamental physics. And while I didn’t think cellular automata as such could be directly applied to fundamental physics, I did think that the core computational phenomena I’d discovered through studying cellular automata might be very relevant. And then in the early 1990s I had an idea. In a cellular automaton, space has a fixed grid-like structure. But what if the structure of space is in fact dynamic, and everything in the universe emerges just from the dynamics of that structure? Finally I felt as if there might be a plausible computational foundation for fundamental physics. </p>\n<p>I wrote about this in <a href=\"https://www.wolframscience.com/nks/chap-9--fundamental-physics/\">one chapter</a> of my 2002 book <em><a href=\"https://www.wolframscience.com/nks/\">A New Kind of Science</a></em>. I don’t know if Ed ever read what I wrote, but in any case it didn’t seem to affect his idea that the universe was a cellular automaton—and to confuse things further, he told quite a few people that was what I was saying too. At first I found this frustrating—and upsetting—but eventually I realized it was just “Ed being Ed”, and there were still plenty of things to like about Ed.</p>\n<p>Nearly twenty years passed. I would see Ed with some regularity. And sometimes I would mention physics. But Ed would just keep talking about his idea that the universe is a cellular automaton. And when we finally made the breakthrough that led in 2020 to our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> it made me a little sad that I didn’t even try to explain it to Ed. The universe isn’t a cellular automaton. But it is computational. And I think that knowing this would have brought a certain intellectual closure to Ed’s long journey and aspirations around physics.</p>\n<p>Ed might have considered physics his single most important quest. But Ed’s life as a whole was filled with a remarkably rich assortment of activities and interests. Computers. Inventions. Companies. Airplanes. MIT. His island. The Soviet Union. Not to mention people, like <a href=\"https://writings.stephenwolfram.com/2016/01/farewell-marvin-minsky-19272016/\">Marvin Minsky</a>, <a href=\"https://www.wolframalpha.com/input?i=john+mccarthy\">John McCarthy</a> and <a href=\"https://www.stephenwolfram.com/publications/short-talk-about-richard-feynman/\">Richard Feynman</a> (as well as <a href=\"https://www.wolframalpha.com/input?i=tom+watson%2C+jr\">Tom Watson</a>, <a href=\"https://www.wolframalpha.com/input?i=richard+branson\">Richard Branson</a>, and many more). And he would tell stories about all these people and things, and more. Sometimes (particularly later in his life) the stories would repeat. But with remarkable regularity Ed would surprise me with yet another—often at first hard-to-believe—story about a situation or topic that I had no idea he’d ever been involved in.</p>\n<p>But what was the “whole Ed story”? I knew a lot of fragments, often quite colorful. But they didn’t seem to fit together into the narrative of a life. And now that Ed is sadly no longer with us, I decided I should really try to “understand Ed” and his story. A few times over the years I had made efforts to ask Ed for systematic historical accounts—and in 2014 I even recorded many hours of oral history with him. But there was clearly much more. And in writing this piece I found myself going through lots of documents and archives—and having quite a few conversations— and unearthing even yet more stories than I already knew. And in the end there’s a lot to say—and indeed this has turned into the most difficult and complicated <a href=\"https://writings.stephenwolfram.com/category/historical-perspectives/\">biographical piece</a> I’ve ever written. But I hope that everything I’ve assembled will help tell the often so-wild-you-can’t-make-this-stuff-up story of that most singular individual who I knew all those years.</p>\n<h2 id=\"the-beginning-of-the-story\">The Beginning of the Story</h2>\n<p>Ed never said much to me about his early life. And in fact I think it was only in writing this piece that I even learned he’d grown up in Los Angeles (specifically, East Hollywood). His parents were both (Jewish) Russian immigrants (his father was born in St. Petersburg; his <a href=\"https://www.findagrave.com/memorial/137987320/rose-j-fredkin\" target=\"_blank\" rel=\"noopener\">mother in Odessa</a>; they met in LA). His <a href=\"https://www.ancestry.com/discoveryui-content/view/72065022:2442\" target=\"_blank\" rel=\"noopener\">father</a>’s university engineering studies had been cut short by the Russian Revolution, and he now had a one-man wholesale electronic parts business. His <a href=\"https://www.ancestry.com/discoveryui-content/view/72065023:2442\" target=\"_blank\" rel=\"noopener\">mother</a> had in her youth been trained as a concert pianist, and died when Ed was 11, leaving a somewhat fragmented family situation. Ed had a <a href=\"https://www.legacy.com/us/obituaries/bostonglobe/name/hedda-casey-obituary?id=24318219\" target=\"_blank\" rel=\"noopener\">half-sister</a>, 14 years older than him, a <a href=\"https://www.ancestry.com/discoveryui-content/view/72065024:2442\" target=\"_blank\" rel=\"noopener\">brother</a> 6 years older, and a <a href=\"https://www.ancestry.com/discoveryui-content/view/72065025:2442\" target=\"_blank\" rel=\"noopener\">sister</a> a year older. As he told it in later oral histories, he got interested in both machines and money very early, repairing appliances for a fee even as a tween, and soon learning about the idea of owning stock in companies. </p>\n<p>But Ed Fredkin’s first piece of public visibility seems to have come in 1948, when he was 13 years old—and it reminds me so much of many of Ed’s later “self-imposed” adventures. There was at that time an exhibition of historic US documents traveling around the country on a train named the <a href=\"https://en.wikipedia.org/wiki/Freedom_Train\" target=\"_blank\" rel=\"noopener\">Freedom Train</a>. And when the train came to Los Angeles, the young Ed Fredkin <a href=\"https://www.newspapers.com/image/381268881/ \" target=\"_blank\" rel=\"noopener\">decided he had to be the first person to see it</a>: </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Beginning-img1.png\"><img loading='lazy'src='https://content.wolfram.com/sites/43/2023/08/sw081823Beginning-img1.png' alt='Click to enlarge' title='Click to enlarge' width='478' height='441'/></a></p>\n<p>The <em>Los Angeles Times</em> published his account of his adventure—a younger but “quintessentially Ed” story:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/Freedom-Train-v3.png\"><img loading='lazy'src='https://content.wolfram.com/sites/43/2023/08/Freedom-Train-v3.png' alt='Click to enlarge' title='Click to enlarge' width='477' height=''/></a></p>\n<p>Ed’s record in high school was at best spotty. But as he tells it, he figured out very early a system for improving the odds in multiple-choice tests, and for example in 9th grade got a top score on a newly instituted (multiple-choice) California-wide IQ test. At the end of high school, Ed applied to Caltech (which was only 13 miles away from where he lived), and largely on the basis of his test scores, was admitted. He ended up spending time working various jobs to support himself, didn’t do much homework, and by his sophomore year—before having to pick a major—dropped out. In 2015 Ed told me a nice story about his time at Caltech: </p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">In 1952–53, I was a student in Linus Pauling&#8217;s class where he lectured Freshman Chemistry at Caltech. After class, one day, I asked Pauling &#8220;What is a superconductor at the highest known temperature?&#8221; Pauling immediately replied &#8220;Niobium Nitride, 18 Kelvin&#8221;. I was puzzled because I had never heard of Niobium, so I looked it up and, with some difficulty found a reference that defined it as a European name for the metal Columbium.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Later that same day, reading a Pasadena newspaper, I saw an article about Pauling: It announced that Pauling had just returned from Europe (London is what I recall) where Pauling, as Chairman of the International Committee on the naming of the elements, had decided that henceforth the metal Columbium would be renamed Niobium.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I recently looked into that matter and discovered that evidently that renaming was part of a USA–Europe Compromise&#8230; In Europe it had been Wolfram and Niobium, in the USA it had been Tungsten and Columbium.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Europe got its way re Niobium and the USA got its way re Tungsten&#8230; Perhaps it was a flip of a coin? Someone might know.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">As a Wolfram, I thought you might be interested (and, of course, perhaps all this is old hat to you&#8230;).</p>\n</blockquote>\n<p>(For what it’s worth, I actually didn’t know this “Wolfram story”, though the details weren’t quite as dramatic as Ed said: the <a href=\"https://en.wikipedia.org/wiki/Niobium\" target=\"_blank\" rel=\"noopener\">&#8220;niobium&#8221; decision</a> was actually made in 1949, without Pauling specifically involved, though Pauling <a href=\"http://scarc.library.oregonstate.edu/coll/pauling/calendar/1952/index.html\" target=\"_blank\" rel=\"noopener\">did indeed travel to London</a> just before the beginning of the 1952 school year.)</p>\n<p>With his interest in machinery, Ed had always been keen on cars, and in his freshman year at Caltech, he also decided to learn to fly a plane. Ed’s older brother, Norman, had joined the Air Force five years earlier. And when he left Caltech—in 1954 at age 19—Ed joined the Air Force too. (If he hadn’t done that, he would have been drafted into the Army.) Ed’s brother Norman (who would spend his whole career in aviation) <a href=\"http://yocumusa.com/sweetrose/everymanatiger/pg09normfredkin.htm\" target=\"_blank\" rel=\"noopener\">had been involved in the Korean War</a>, particularly doing aerial reconnaissance—here pictured with his plane (and, no, there don’t seem to be any Air Force pictures of Ed himself):</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://www.airandspaceforces.com/PDF/MagazineArchive/Documents/2000/June%202000/0600korea.pdf\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Beginning-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Beginning-img3.png' alt='Click to enlarge' title='Click to enlarge' width='433' height='284'/></a></p>\n<p>By the time Ed joined the Air Force, the Korean War was over. Ed was assigned to an <a href=\"https://en.wikipedia.org/wiki/Williams_Air_Force_Base\" target=\"_blank\" rel=\"noopener\">airbase in Arizona</a>, and by the summer of 1955 he had qualified as a fighter pilot. Ed was never officially a “test pilot”, but he told me stories about figuring out how to take his plane higher than anyone else—and achieving weightlessness by flying his plane in a perfect free-fall trajectory by maintaining an eraser floating in midair in front of him. </p>\n<p>By 1956 Ed had been grounded from flying as a result of asthma, and was now at an <a href=\"https://www.eglin.af.mil/\" target=\"_blank\" rel=\"noopener\">airbase in Florida</a> as an “intercept controller”—essentially an air traffic controller responsible for guiding fighters to intercept bombers. It was a time when the Air Force was developing the <a href=\"https://www.ll.mit.edu/about/history/sage-semi-automatic-ground-environment-air-defense-system\" target=\"_blank\" rel=\"noopener\">SAGE (Semi-Automatic Ground Environment) air defense system</a>—a huge project whose concept was to use computers to coordinate data from many radars so as to be able to intercept Soviet bombers that might attack the US (cf. <em><a href=\"https://www.wolframalpha.com/input?i=dr+strangelove\">Dr. Strangelove</a></em>, etc.). The center of SAGE development was <a href=\"https://www.ll.mit.edu/\" target=\"_blank\" rel=\"noopener\">Lincoln Lab</a> (then part of MIT) in Lexington, MA—with IBM providing computers, Bell (AT&#038;T) providing telecommunications, <a href=\"https://www.rand.org/\" target=\"_blank\" rel=\"noopener\">RAND</a> providing algorithms, etc. And in mid-1956 the Air Force sent a group—including Ed—to test the next phase of SAGE. But as Ed tells it, they were soon informed that actually there would be a one-year delay. </p>\n<p>At the time, the SAGE project was busily trying to train people about computers, and some people from the Air Force stayed in the Boston area to participate in this. As Ed tells it, however, he was the only one who didn’t drop out of the training—and over the course of a year it taught him “much of what was then known about computer programming and computer hardware design”. There were at the time only a few hundred people in the world who could call themselves programmers. And Ed was now one of them. (Perhaps he was even “the world’s best”.) </p>\n<h2 id=\"computers!\">Computers!</h2>\n<p>Having learned to program, Ed remained at Lincoln Lab, paid by the Air Force, doing what amounted to computational “odd jobs”. Often this had to do with connecting systems together, or coming up with “clever hacks” to overcome particular system limitations. Occasionally it was a little more algorithmic—like when Sputnik was launched in 1957, and Ed got pulled into a piece of “emergency programming” for orbit calculations. </p>\n<p>Ed told many stories about “hacking” the bureaucracy at the Air Force (being given a “Secret” stamp so he could read his own documents; avoiding being sent for a year to the Canadian Arctic by finding a loophole associated with his wife being pregnant, etc.)—and in 1958 he left the Air Force (though he would remain a captain in the reserves for many years), but stayed on at Lincoln Lab. Officially he was there as an “administrative assistant”, because—without a degree—that was all they could offer him. But by then he was becoming known as a “computer person”—with lots of ideas. He wanted to start his own company. And (as he tells it) the very first potential customer he visited was an MIT-spinoff acoustics firm called <a href=\"https://en.wikipedia.org/wiki/Raytheon_BBN\" target=\"_blank\" rel=\"noopener\">Bolt Beranek &#038; Newman (BBN)</a>. And the person he saw there was their “vice president of engineering psychology”—a certain <a href=\"https://en.wikipedia.org/wiki/J._C._R._Licklider\" target=\"_blank\" rel=\"noopener\">J. C. R. &#8220;Lick&#8221; Licklider</a>—who persuaded Ed to join BBN to “teach them about computers”. </p>\n<p>It didn’t really come to light until he was at BBN, but while at Lincoln Lab Ed had made what would eventually become his first lasting contribution to computer science. He thought of it as a new way of storing textual information in a computer, and he called it “TRIE memory” (after “reTRIEval”). Nowadays we’d call it the <a href=\"https://reference.wolfram.com/language/ref/datastructure/ByteTrie.html\">trie (or prefix tree) data structure</a>. Here it is for some common words in English made from the letters of “wolf”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img1.png' alt='' title='' width='373' height='240'> </div>\n</p></div>\n<p>Licklider persuaded Ed to write a paper about tries—which appeared in 1960, and for a couple of decades was essentially Ed’s only academic-style publication:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img2.png' alt='Click to enlarge' title='Click to enlarge' width='487' height='136'/></a></p>\n<p>The paper has a pretty clear description of tries, even with some nice diagrams:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img3.png' alt='Click to enlarge' title='Click to enlarge' width='488' height='237'/></a></p>\n<p>Even in analyzing the performance of tries, there was only the faintest hint of math in the paper—though Ed realized (probably with input from Licklider) that the efficiency of tries would depend on the <a href=\"https://reference.wolfram.com/language/ref/Entropy.html\">Shannon-style redundancy</a> of what they were storing, and he ran Monte Carlo simulations to investigate this:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img4.png' alt='Click to enlarge' title='Click to enlarge' width='488' height='316'/></a></p>\n<p>(He explains: “The test program was written in FORTRAN for the IBM 709. The program is composed of 42 subroutines, of which 19 were coded specially for this program and 23 were taken from the library.”)</p>\n<p>Tries didn’t make a splash when Ed first introduced them—not least because computers didn’t really have the memory then to make use of them. I think I first heard about them in the late 1970s in connection with spellchecking, and nowadays they’re widely used in lots of text search, bioinformatics and other applications.</p>\n<p>Ed had apparently first started talking about tries when he was still in the Air Force. As he explained it to me in 2014:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">The Air Force [people] had no idea [what I was talking about]. But I kept on [saying] “I need to find someone who knows something about this that can critique it for me.” And someone says to me, “There’s a guy at MIT who deals in something similar, he calls it lists”. And that was John McCarthy. So, I call up, I get a secretary and, you know, I make a date, and I go to MIT and in building 56 with the computation center, I go to his office and the secretary says he’s somewhere out in the hall. I see some guy wandering back and forth. I go up and say, “You John McCarthy?” He says, “Yes.” So, I say, “I’ve had this idea—” I can’t remember if I was in uniform or not; I might’ve been. I said, “I had this idea, and I’ve written a program and tested it. And might you take a look?” Then he takes this thing, and he starts to read it. </p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Then he did something that struck me as very weird. He turned around slowly and started walking away, he’s reading and walk, walk, walk, walk, stop. Turns around, walk, walk, walk, walk, back slowly, you know. Finally, he comes back and he stops and he reads and reads. And he’s obviously angry. And I thought, “This is weird.” I said “Does it make sense or anything?” He says, “Yes, it makes sense.” And I said, “Well, what’s up?” He says, “Well, I’ve had the same idea.” And I said, “Oh.” He says, “But I’ve never written it down.” And I said, “Oh, okay. So, do you think I ought to work on it or do something?” He says, “Yeah”. So, that’s how I met John McCarthy. </p>\n</blockquote>\n<p>Ed remained friends with McCarthy for the rest of McCarthy’s life, and involved him in many of his endeavors. In 1956 McCarthy had been one of the organizers of the conference that coined the term “artificial intelligence”, and in 1958 McCarthy began the development of <a href=\"https://en.wikipedia.org/wiki?curid=18016\" target=\"_blank\" rel=\"noopener\">LISP</a> (which was based on <a href=\"https://reference.wolfram.com/language/ref/datastructure/LinkedList.html\">linked lists</a>). I have to say I wish I’d known Ed’s story with McCarthy much earlier; I would have handled my own interactions with McCarthy differently—because, as it was, over the course of various encounters from 1981 to 2003 I never persisted very far beyond the curmudgeon stage.</p>\n<p>Back around 1958, the circle of “serious computer people” in the Boston area wasn’t very large—and another was <a href=\"https://writings.stephenwolfram.com/2016/01/farewell-marvin-minsky-19272016/\">Marvin Minsky</a> (who I knew for many years). Between Ed and Licklider, both McCarthy and Minsky became consultants at BBN, and all of them would have many interactions in the years to come. </p>\n<p>But in late 1959 there was another entrant in the Boston computer scene: the <a href=\"https://en.wikipedia.org/wiki/PDP-1\" target=\"_blank\" rel=\"noopener\">PDP-1 computer</a>, designed by a certain <a href=\"https://en.wikipedia.org/wiki/Ben_Gurley\" target=\"_blank\" rel=\"noopener\">Ben Gurley</a> for a new company named <a href=\"https://en.wikipedia.org/wiki/Digital_Equipment_Corporation\" target=\"_blank\" rel=\"noopener\">Digital Equipment Corporation (DEC)</a> that had essentially spun off from Lincoln Lab and MIT. BBN was the first customer for the PDP-1, and Ed was its anchor user:</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://www.computerhistory.org/pdp-1/dd09f9c9fc68e3d1750284ba8a9e0cab/\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img5.png' alt='Click to enlarge' title='Click to enlarge' width='351' height='363'/></a></p>\n<p>John McCarthy had had the “theoretical” <a href=\"https://en.wikipedia.org/wiki/Time-sharing\" target=\"_blank\" rel=\"noopener\">idea of timesharing</a>, whereby multiple users could work on a single computer. Ed figured out how to make it practical on the PDP-1, in the process inventing what would now be called asynchronous interrupts (then the “sequence break system”). And so began a process which led BBN to become a significant force in computing, the creation of the internet, etc.</p>\n<p>But in 1961, Ed and a certain <a href=\"https://www.taosnews.com/obituaries/roland-lazarus-silver/article_c3b520ae-59db-5cb4-a2cf-ac19fa624ff8.html\" target=\"_blank\" rel=\"noopener\">Roland Silver</a>, who also worked at BBN, decided to quit BBN—and, strangely enough, to move to Brazil, where they were enamored of the <a href=\"https://en.wikipedia.org/wiki/J%C3%A2nio_Quadros\" target=\"_blank\" rel=\"noopener\">recently elected new president</a>. But when that new president unexpectedly resigned, they abandoned their plan. And when BBN didn’t want them back, Ed decided to start a company, initially doing consulting for DEC. As Ed tells it, he and Roland Silver were such good friends and had so much they talked about that together they couldn’t get anything done, so they decided they’d better split up.</p>\n<p>As I was writing this piece, I decided to look up more about Roland Silver—who I found out had been a college roommate of Marvin Minsky’s at Harvard, and had had a <a href=\"https://dl.acm.org/profile/81408597746\" target=\"_blank\" rel=\"noopener\">long career in math, etc. at MITRE</a> (the holding company for Lincoln Lab). But I also remembered that many years ago I’d received letters and a <a href=\"https://archive.org/details/amygdala-a-newsletter-of-fractals-m-the-mandelbrot-set-issue-11/mode/2up\" target=\"_blank\" rel=\"noopener\">rather new-age newsletter</a> from a certain “Rollo Silver”: </p>\n<p><a class=\"magnific image sourced\" data-url=\"https://archive.org/details/amygdala-a-newsletter-of-fractals-m-the-mandelbrot-set-issue-11/mode/2up\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img6.png' alt='Click to enlarge' title='Click to enlarge' width='378' height='111'/></a></p>\n<p>Could it be the same person? Yes! And in my archives I also found an ad:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img7.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img7.png' alt='Click to enlarge' title='Click to enlarge' width='269' height='271'/></a></p>\n<p>Some time after my work on cellular automata in the 1980s, Roland Silver—together with my longtime friend <a href=\"https://www.rudyrucker.com/\" target=\"_blank\" rel=\"noopener\">Rudy Rucker</a>—started a newsletter about cellular automata, notably not mentioning Ed, but including a <a href=\"https://archive.org/details/cellularautomatiste/page/n9/mode/2up\" target=\"_blank\" rel=\"noopener\">colorful bio for Silver</a>:</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://archive.org/details/cellularautomatiste/page/n9/mode/2up\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img8.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Computers-img8.png' alt='Click to enlarge' title='Click to enlarge' width='397' height='149'/></a></p>\n<h2 id=\"“triple-i”-(iii)\">“Triple-I” (III)</h2>\n<p>But back to Ed and his story. It was 1961, and Ed had quit his job at BBN. In 1957, he’d met on a Cape Cod beach a<a href=\"https://www.newspapers.com/image/545238599/?article=89cf6add-313a-4127-8676-5526d772195a&#038;focus=0.5617748,0.06144986,0.6622979,0.3747436&#038;xid=3398&#038;_gl=1*y23b1x*_gcl_au*OTEyODgxMTI0LjE2ODk5NzQwNjE.*_ga*MTYwNjU0NTk3Mi4xNjg5OTcyODQw*_ga_4QT8FMEX30*NWJjYmY3ODMtN2JkOS00OTdiLTkyMTYtZjg3YjIwYzA2NGE3LjUuMS4xNjkwMjQwNDgyLjM5LjAuMA..&#038;_ga=2.66708710.914889863.1690222672-1606545972.1689972840\" target=\"_blank\" rel=\"noopener\"> woman from Western Massachusetts named Dorothy Abair </a>(who was at the time working at a beauty salon)—and six weeks later they’d married, and now had a 3-year-old daughter. Ed had already lined up some consulting with DEC, and as Ed tells it, with a little “hacking” of bank loans, etc. he was able to officially start <a href=\"https://en.wikipedia.org/wiki/Information_International,_Inc.\" target=\"_blank\" rel=\"noopener\">Information International Incorporated (III)</a>—with a tiny office in Maynard, MA (home of DEC). But then, one day he gets a call from the <a href=\"https://www.whoi.edu/who-we-are/\" target=\"_blank\" rel=\"noopener\">Woods Hole Oceanographic Institute</a>. He drives down to Woods Hole with a certain <a href=\"https://en.wikipedia.org/wiki/Henry_Stommel\" target=\"_blank\" rel=\"noopener\">Henry Stommel</a>—an oceanography professor at Harvard—who tells him about a “vortex ocean model”, and asks Ed if he can <a href=\"https://bitsavers.org/pdf/dec/decus/confProceedings/DECUS_1962.pdf\" target=\"_blank\" rel=\"noopener\">program it on a PDP-1</a> so that it displays ocean currents on a screen. And the result is that III soon has a contract for $10k (about $100k today) to do this.</p>\n<p>I might add a small footnote here. Years later I was talking to Ed about the origins of cellular automata, and he tells me that a certain Henry Stommel had told him that there were cellular automaton models of sand dunes from the 1930s. At the time—before the web—I couldn’t easily track down who Henry Stommel was (and I had no idea how Ed knew him), and to this day I don’t know what those sand dune models might have been. </p>\n<p>But in any case, Ed’s interaction with Woods Hole led to what became III’s first major business: digital reading of film. As <a href=\"https://www.youtube.com/watch?v=UMCVkEyfEG0&#038;list=PLZKOq5_Vcp4GGdZHCzKzr38h9MhkIqVJT&#038;index=13\" target=\"_blank\" rel=\"noopener\">Ed tells it</a>:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">At Woods Hole &#8230; they had these meters which would measure how fast the ocean current was going and which way—and recorded it on 16 mm film with little tiny lights and a little fiber optic thing. And they had built a machine to read that film. I looked at the machine and said “That’ll never work”. And they said “Who are you? Of course it’ll work”, and so on, so forth. OK, so some months later they call me up and say it didn’t work.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I have to tell you this but this is insanely funny. So I decide I’m going to make a film reader and here’s how I’m going to do it. I knew there was a 16 mm projector you could rent from a company and you could stop it and then say “Advance one frame” by clicking and it would just advance one frame at a time. So I thought: say I take the lightbulb out and put a photomultiplier in and point it at the screen of the computer. Then light will come from the screen, go through the lens and be focused on the film, and some would go through the film to the photomultiplier and I would be able to tell how much light got through. And we could write a program to do the rest.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">That was my idea, OK. </p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">So not having any money, we rented that projector and I got Digital (DEC) to let me use their milling machine and I bought the photomultiplier tube, and I got Ben Gurley to design the circuitry and connect it to the computer. But there was one more thing. The photomultiplier tube was like a vacuum tube but it had like 16 pins and a very odd connector that no one had. But I thought “Lincoln Labs has parts for everything in their electronics warehouse”. So I called someone I used to work with there, and said “Look, do me a favor and sneak into the parts area, take that part and just give it to me. I’ve ordered one but I’m not going to get it for a while and when I get it I’ll give it to you and you can put it back so it’s not actually a theft.” And he said “OK, I’ll do it” but he asked me why I wanted it and I told him “Well, I’m doing this stuff for Woods Hole to read some film with a computer”.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">OK, so he gave me the part and we get it going right away and we’re reading the film, and that solved the problem. But meanwhile this very funny thing happened. Someone from Lincoln Labs found out about all this and said “Hey, you’re reading some kind of film. Is that what you used that thing for?” And I said “Yeah”. And they said “Well, we tried to read some films so we built a gadget and did the same thing you did: we pointed it at the screen of the computer, but we can’t make the software work”. And I said “OK, well, come down and tell me about it”. So they come down and what happens is this. There’s some army people and they have a radar that’s looking at a missile coming in and records on film from an oscilloscope. And they asked could we read this. And to make a long story short they signed another contract&#8230;.</p>\n</blockquote>\n<p>The whole setup was eventually captured in a <a href=\"https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/3340359\" target=\"_blank\" rel=\"noopener\">patent entitled simply &#8220;High-Speed Film Reading&#8221;</a>:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823III-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823III-img1.png' alt='Click to enlarge' title='Click to enlarge' width='567' height='444'/></a></p>\n<p>And actually this wasn’t Ed’s first patent. That had been filed in 1960, while Ed was at BBN—and it was for a <a href=\"https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/3105593\" target=\"_blank\" rel=\"noopener\">mechanical punched card sorter</a>, with arrays of metal pins and the like, and no computer in evidence:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823III-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823III-img2.png' alt='Click to enlarge' title='Click to enlarge' width='568' height='291'/></a></p>\n<p>III ended up discovering that there were many applications—military and otherwise—for film readers. But their Woods Hole relationship led in another direction as well: computer graphics and data visualization. By 1963 there were perhaps 300,000 oceanographic stations recording their data on punched cards, and the idea was to take this data and produce from it a “<a href=\"https://www.pnas.org/doi/epdf/10.1073/pnas.50.2.396\" target=\"_blank\" rel=\"noopener\">computer-compiled oceanographic atlas</a>”. The result was a paper:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823III-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823III-img3.png' alt='Click to enlarge' title='Click to enlarge' width='605' height='150'/></a></p>\n<p>And with statements like “Only a high-speed computer has the capacity and speed to follow the quickly shifting demands and questions of a human mind exploring a large field of numbers” the paper presented visualizations like:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823III-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823III-img4.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='276'/></a></p>\n<p>These various developments put III in the center of the emerging field of film-meets-computers systems. The company grew, moving its center of operations to Los Angeles, not least to be near the <a href=\"https://en.wikipedia.org/wiki/System_Development_Corporation\" target=\"_blank\" rel=\"noopener\">Systems Development Corporation (SDC)</a> which RAND had spun off as its software arm in response to the SAGE project. </p>\n<p>But Ed was always having new ideas for III, and defining new directions. Ed had brought Minsky and McCarthy into III as board members and consultants, and for example in 1964 III was <a href=\"https://www.softwarepreservation.org/projects/LISP/lisp2/Fredkin-Proposal-LISP_II_Programming_System.pdf\" target=\"_blank\" rel=\"noopener\">proposing to SDC</a> a project to make a new version of LISP (and, yes, with no obvious film-meets-computers applications). The proposal gives some insight into the state of III at the time. It says that “From a one-man operation [in 1962], I.I.I. has grown to the point where our gross volume of business for 1964 is in the neighborhood of $1 million [about $10 million today]”. It explains that III has four divisions: Mathematical and Programming Services, Behavioral Science, Operations, and “New York”. It goes on to list various things III is doing: (1) LISP; (2) Inductive Inference on Sequences; (3) Computer Time-Sharing; (4) Programmable Film Readers; (5) The World Oceanographic Data Display System; and (6) Computer Display Systems.</p>\n<p>It’s certainly an eclectic collection, reflecting, as such things often do, the character of the company’s founder. From a modern perspective, one item that catches one’s attention is:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823III-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823III-img5.png' alt='Click to enlarge' title='Click to enlarge' width='517' height='552'/></a></p>\n<p>One can think of it as an early attempt at AI/machine learning—which 60 years later still hasn’t been solved. (GPT-4 says the next letter should be Q, not O.)</p>\n<p>But distractions or not, it was a talented team that assembled at III—with lots of cross-fertilization with MIT. III’s business progressively grew, and perhaps it outgrew Ed—and in 1965 Ed stepped down as CEO. In 1968 he left entirely and (as we’ll discuss below) went to MIT, leaving III in the hands of <a href=\"https://www.youtube.com/watch?v=E46IgRenBWs\" target=\"_blank\" rel=\"noopener\">Al Fenaughty</a>, who, years later (and after nearly 30 years at III), would become the chairman of <a href=\"https://yandex.com/\" target=\"_blank\" rel=\"noopener\">Yandex</a>.</p>\n<p>As someone who’s curious about the ways of company founders, I asked Ed many times about his departure from III. He usually just said: “I had a partner who died”. But it’s only now that I’ve pieced together, partly from my 2014 oral history with Ed, what happened. Ed described it to me as the greatest tragedy of his life.</p>\n<p>Shortly after he set up III, Ed persuaded Ben Gurley (designer of the PDP-1) to leave DEC and join him at III. I think Ed had hoped to build computers at III, with Gurley as their designer. But on November 7, 1963, in Concord, MA, just a few miles from where I am as I write this, Ben Gurley was murdered—by a single revolver shot through his dining room window as he was about to sit down for dinner with his wife and 7 children. An engineer from DEC (and Lincoln Labs)—about whom Gurley had recently complained to the police—was arrested, and eventually convicted of the crime (after Ed hired a private detective to help). It later turned out that a few years earlier the same engineer was likely also responsible for shooting (though not killing) another engineer from DEC.</p>\n<p>I had always assumed that Ed’s decision to leave III happened just after his “partner had died”. But I now realize that Gurley’s death early in the history of III caused III to go on its path of making things like film readers, rather than the DEC- or IBM-challenging computers I think Ed had hoped for.</p>\n<p>Even after Ed left active management of III, he was still its chairman. And in late 1968 something would happen that would change his life forever. Taking tech companies public on the “over-the-counter” market had become a thing, and a broker offered to take III public. And on November 26, 1968, III <a href=\"https://www.sec.gov/news/digest/1968/dig120268.pdf\" target=\"_blank\" rel=\"noopener\">filed its SEC paperwork</a>:</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://www.sec.gov/news/digest/1968/dig120268.pdf\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823III-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823III-img6.png' alt='Click to enlarge' title='Click to enlarge' width='569' height='218'/></a></p>\n<p>III’s “principal product to date” is described as a “programmable film reader”, but the paperwork notes that as of October 31, 1968, the company has no film readers on order—though there are orders for its new microfilm reader, which it hasn’t delivered yet. It also says that proceeds from the offering will be used to fund its “proposed optical character recognition project”. But for our purposes what’s perhaps more significant is that the paperwork records that Ed owns 57.7% of the company, with the Edward Fredkin Charitable Foundation owning 0.4%.</p>\n<p>On January 8, 1969, III went public, and Ed was suddenly, at least on paper, worth more than $10M (or more than $80M today). Two years later (perhaps as soon as a lockup period expired), Ed cashed out, with the SEC notice indicating that Ed would be “repaying personal indebtedness to a bank incurred by him for reasons unrelated to the company or its business” (presumably a loan he’d taken out before he could achieve liquidity):</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://www.sec.gov/news/digest/1971/dig040571.pdf\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823III-img7.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823III-img7.png' alt='Click to enlarge' title='Click to enlarge' width='568' height='135'/></a></p>\n<p>So now Ed—at age 37—was wealthy. And in fact the money he made from III would basically last the rest of his life, even through a long sequence of subsequent business failures. </p>\n<p>III&#8217;s OCR project was never a great success, but III became a key company in digital-to-film systems (relevant to both movies and printing), and in the early 1970s created some of the very first computer-generated special effects, that eventually made it into movies like <em>Star Wars</em>. III&#8217;s stock price hovered around $10 per share for years, and in 1996—after PostScript had pretty much taken the market for prepress printing systems—III was <a href=\"http://www.fundinguniverse.com/company-histories/autologic-information-international-inc-history/\" target=\"_blank\" rel=\"noopener\">sold to Autologic</a> for $35M in stock, then in 2001 Autologic was sold to <a href=\"https://en.wikipedia.org/wiki/Agfa-Gevaert\" target=\"_blank\" rel=\"noopener\">Agfa</a> for $42M. </p>\n<h2 id=\"the-island\">The Island</h2>\n<p>When III went public in 1969 it was the height of the Cold War (which probably didn’t hurt III’s military sales). And many people—including Ed—thought World War III might be imminent. And so it was that in 1970 Ed decided to buy an island in the Caribbean, close enough to the tropics, he told me subsequently, that, he assumed (incorrectly according to current models), radioactive fallout from a nuclear war wouldn’t reach it. </p>\n<p>Apparently Ed was sitting in a dentist’s office when he saw an “Island for Sale” ad in a newspaper. The seller was a shipwreck-scavenging treasure hunter named <a href=\"https://www.sportdiver.com/destinations/british-virgin-islands/last-pirate-caribbean\" target=\"_blank\" rel=\"noopener\">Bert Kilbride</a>—sometimes called “the last pirate of the Caribbean”—who had started to develop the island (and for several years would manage it for Ed). It’s a fairly small island (about 125 acres, or 0.2 square miles)—in the British Virgin Islands. And its name is <a href=\"https://en.wikipedia.org/wiki/Mosquito_Island\" target=\"_blank\" rel=\"noopener\">Mosquito Island</a> (or sometimes, with some historical justification, Moskito Island). And when Ed bought it, it probably cost something under $1M. (Richard Branson bought the nearby but smaller <a href=\"https://en.wikipedia.org/wiki/Necker_Island_(British_Virgin_Islands)\" target=\"_blank\" rel=\"noopener\">Necker Island</a> in 1978.)</p>\n<p>I visited Ed’s island in January 1982—the first time I met Ed. And, yes, there was a certain “lair of a Bond villain” (think: <em><a href=\"https://www.wolframalpha.com/input?i=Dr.+No\">Dr. No</a></em>) vibe to the whole thing. Here are pictures I took from a boat leaving the island (notice the just-visible seaplane parked at the island):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Island-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Island-img1.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='201'/></a></p>\n<p>There was a small resort (and restaurant) on the island, named Drake’s Anchorage (built by the previous owner): </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Island-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Island-img2.png' alt='Click to enlarge' title='Click to enlarge' width='577' height='233'/></a></p>\n<p>And, yes, there were beaches on the island (though I myself have never been much of a beach-goer):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Island-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Island-img3.png' alt='Click to enlarge' title='Click to enlarge' width='460' height='297'/></a></p>\n<p>And, in keeping with the Bond vibe, there was a seaplane too:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Island-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Island-img4.png' alt='Click to enlarge' title='Click to enlarge' width='460' height='300'/></a></p>\n<p>There was one house on the island, here pictured from the plane (it so happened that when I visited the island, I was learning to fly small planes myself—so I was interested in the plane):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Island-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Island-img5.png' alt='Click to enlarge' title='Click to enlarge' width='460' height='291'/></a></p>\n<p>Visiting a <a href=\"https://en.wikipedia.org/wiki/Anegada\" target=\"_blank\" rel=\"noopener\">nearby island</a>—with its very rundown airport sign—gives some sense of the overall area:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Island-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Island-img6.png' alt='Click to enlarge' title='Click to enlarge' width='460' height='301'/></a></p>\n<p>Ed claimed it was difficult to run the resort on his island, not least because, he said, “the British Virgin Islands have the lowest average worker productivity in the world”. But he nevertheless, for example, had a functioning restaurant, and here I am there in 1982, along with Charles Bennett, about whom we’ll hear more later:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823Island-img7-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823Island-img7-min.png' alt='Click to enlarge' title='Click to enlarge' width='460' height='380'/></a></p>\n<p>When people talked about Ed, his island was often mentioned, and it projected a general image of overall mystique and extreme wealth. In 1983 a movie called <em><a href=\"https://www.wolframalpha.com/input?i=wargames\">WarGames</a></em> came out, featuring a reclusive military-oriented computer expert named “Professor Falken”—who had an island. Many people assumed Falken was based on Fredkin (and it now says so all over the internet). However, in writing this piece, I decided to find out what was actually true—so I asked one of the writers of the movie, <a href=\"https://en.wikipedia.org/wiki/Walter_F._Parkes\" target=\"_blank\" rel=\"noopener\">Walter Parkes</a>. He responded, and, yes, fact is often even stranger than fiction: </p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Unfortunately I can confirm that Ed was not the inspiration for Stephen Falken. The character was inspired by Steven [<em>sic</em>] Hawking. (Falken = Falcon = Hawking) The movie was first conceived to be about two characters, a young super-genius born into a family incapable of acknowledging his gifts, and a dying scientist in need of a protégé. In the first several drafts Falken was confined to a wheel-chair and was working on understanding the big bang, for which he had created a computer simulation. Little known fact—while writing the character, we had one person in mind to play the role: John Lennon, who was murdered shortly before we finished the script.</p>\n</blockquote>\n<p>(By the way, in a moment of “fact follows fiction”, <em>WarGames</em> featured a computer with lots of flashing lights. I happened to see the movie with <a href=\"https://www.wolframalpha.com/input?i=danny+hillis\">Danny Hillis</a>, and as we were walking out of the movie, I said to Danny “Perhaps your computer should have flashing lights too”. And indeed flashing lights became a signature feature of Danny’s <a href=\"https://en.wikipedia.org/wiki/Connection_Machine\" target=\"_blank\" rel=\"noopener\">Connection Machine</a> computer, as later seen in movies like <a href=\"https://www.wolframalpha.com/input?i=jurassic+park\"><em>Jurassic Park</em></a>.)</p>\n<h2 id=\"project-mac\">Project MAC</h2>\n<p>After he left III in 1968, Ed’s next stop would be MIT, and specifically <a href=\"https://www.darpa.mil/about-us/timeline/project-mac\" target=\"_blank\" rel=\"noopener\">Project MAC</a> (the “Multiple Access Computer” Project). But actually Ed had already been involved much earlier with Project MAC. In many ways the project was a follow-on to what Ed had been doing at BBN on timesharing. </p>\n<p>In 1963 Ed wrote a long survey article on timesharing:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img1.png' alt='Click to enlarge' title='Click to enlarge' width='554' height='577'/></a></p>\n<p>The introduction contains a rather charming window onto the view of computers at the time:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img2.png' alt='Click to enlarge' title='Click to enlarge' width='402' height='241'/></a></p>\n<p>And the ads interspersed through the article give a further sense of the time:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img3.png' alt='Click to enlarge' title='Click to enlarge' width='576' height='369'/></a></p>\n<p>As illustrations of what can be done with an interactive timeshared computer, there’s a picture from Ed’s vortex ocean simulation—as well as an example of an online “book” about LISP:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img4.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='389'/></a></p>\n<p>And, yes, already a kind of “cloud computing” story:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img5.png' alt='Click to enlarge' title='Click to enlarge' width='360' height='162'/></a></p>\n<p>There’s also a description of Project MAC—that had just been funded by the <a href=\"https://www.darpa.mil/\" target=\"_blank\" rel=\"noopener\">Advanced Research Projects Agency (now DARPA)</a>. The article said that the “MAC” stood either for “Multiple Access Computer” or “Machine-Aided Cognition”. It included various sections on what might be possible with timesharing:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img6.png' alt='Click to enlarge' title='Click to enlarge' width='421' height='306'/></a></p>\n<p>The main text of the article ends with a rousing (?) vision of AI taking over from humans (and, yes, even though this is from 60 years ago it’s not so different from what at least some people might say about the “AI future” today):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img7.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img7.png' alt='Click to enlarge' title='Click to enlarge' width='640' height='345'/></a></p>\n<p>But there’s a curious piece of backstory to Project MAC—from 1961—that appears as a footnote to Ed’s article:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img8.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img8.png' alt='Click to enlarge' title='Click to enlarge' width='571' height='275'/></a></p>\n<p>Ed told me versions of this story many times. McCarthy had failed to get tenure at MIT, and was looking for another job. (Yes, in retrospect this seems remarkable given all the things he’d already done by then. But those things were computer science—and MIT didn’t yet have a CS department; McCarthy was in the EE department.) Ed, Minsky and McCarthy were going to an SDC meeting in Los Angeles, and while he was out there McCarthy was going to interview at Caltech (his undergraduate alma mater). They had a free evening, and Ed suggested they meet “someone interesting”. Ed remembered Linus Pauling from his time at Caltech. But Pauling wasn’t in. So Minsky suggested they call <a href=\"https://www.stephenwolfram.com/publications/short-talk-about-richard-feynman/\">Richard Feynman</a>. And he was in, and invited them over to his house.</p>\n<p>Feynman apparently showed them things like his nanotech-inspiring tiny motor, etc., but somehow the discussion shifted to AI. And Minsky mentioned work a <a href=\"https://www.genealogy.math.ndsu.nodak.edu/id.php?id=61077\" target=\"_blank\" rel=\"noopener\">student of his</a> was doing on the “AI problem” of symbolic integration. Then McCarthy started to explain ways a computer could do algebra. Then, as Ed told it to me in 2014:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Feynman produces this sheaf of papers to show us. It was all algebra. And he says “There’s a problem. I’ve done this calculation, and it’s close to 50 pages. A graduate student has done it too, and Murray Gell-Mann has done it. And the only thing we know for sure is that our three results are mutually inconsistent. And the only conclusion we can arrive at is that a person can’t do this much algebra with the hope of getting it right.” And so the question was could there be some system that could help do a problem like that? So what happened is Marvin [Minsky] and I basically fleshed out the idea of a mathematical thing. And it was agreed that we would do it. Marvin and I decided to divide this task up, that I would do one part, and he would do another. Now, we had one bad idea in there, OK. It’s partly Feynman’s fault, but it’s also Marvin and my fault. He was convinced you could not do [math] by typing it. It had to have some kind of handwriting recognition. So, it was decided I would do the handwriting recognition&#8230;</p>\n</blockquote>\n<p>And although I didn’t know this until I was writing this piece, it turns out the original proposal for Project MAC was actually based on the idea of building a system for mathematics, and “Project MAC” was originally the “Project on Mathematics and Computation”. Pretty soon, though, the emphasis of Project MAC would shift to the “infrastructure” of timeshared computing. But there was still a math effort, which in time became the <a href=\"https://en.wikipedia.org/wiki/Macsyma\" target=\"_blank\" rel=\"noopener\">MACSYMA</a> system for computer algebra (written in LISP by students and grandstudents of Minsky). </p>\n<p>And here this intersects with my personal story. Because many years later (starting in 1976) <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">I would use that system</a>—along with other early computer algebra systems—to do all sorts of physics calculations. My archives still contain an example of what it was like in 1980 to log in to “Project MAC” over the ARPANET (my username was “swolf” in those days; note the system message, the presence of 15 MITishly-named “lusers” altogether, and yes, mail): </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img9.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img9.png' alt='Click to enlarge' title='Click to enlarge' width='580' height='399'/></a></p>\n<p>But, actually, in late 1979 I had already decided to “do my own thing” and build my own system for doing mathematical computation, and eventually much more. And indeed when I first met Ed in 1982 I had recently finished the <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">first version of SMP</a>, and to commercialize it I had started my first company. In 1986 I started to build <a href=\"https://www.wolfram.com/mathematica/\">Mathematica</a> (and what’s now <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>)—which was released in 1988. Ed started using Mathematica very soon after it was released, and basically continued to do so for the rest of his life.</p>\n<p>But picking up the original Project MAC narrative from 1963: the old group from BBN had dispersed but were still <a href=\"https://dl.acm.org/doi/pdf/10.1145/1461551.1461559\" target=\"_blank\" rel=\"noopener\">writing together about timesharing</a> (and when they said a “debugging system” they meant essentially what we would now call an operating system):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img10.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MAC-img10.png' alt='Click to enlarge' title='Click to enlarge' width='621' height='207'/></a></p>\n<p>And when Project MAC launched in 1963, its “steering committee” included Minsky, Gurley—and Ed. (John McCarthy had landed at Stanford, where he would remain for the rest of his life. I first met him in 1981, at a time when Stanford was trying to recruit me. There was a lunch with the CS department; people went around the room and introduced themselves. McCarthy unhelpfully—and confusingly—said he was “John Smith”.)</p>\n<h2 id=\"ed-at-mit\">Ed at MIT</h2>\n<p>In 1968, Ed left III—and Minsky, together with Licklider (who had by then become director of Project MAC), persuaded the MIT EE department to hire Ed as a visiting professor for the year. Ed had been spending most of his time at III in Los Angeles, but III also had a <em>pied-à-terre</em> in the Boston area, and indeed its IPO documents listed its address as 545 Technology Square, Cambridge—the very building in which Project MAC was located.</p>\n<p>At MIT, Ed invented and taught a freshman course on “Problem Solving”. He told me many times one of his favorite “problem exercises”. Imagine there’s a person who can cure anyone who’s sick just by touching them. How could one set things up to make the best use of this? I must say I never find such implausible hypotheticals terribly interesting. But Ed was proud of a solution that he’d come up with (I think in discussion with Minsky and McCarthy) that involved systematically shuttling millions of people past the healer.</p>\n<p>This probably didn’t come from that particular course, but here are some notes I found in an archive of Ed’s papers at MIT that perhaps suggest some of the flavor of the course (we’ll talk about Ed’s interest in the Soviet Union later):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MIT-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MIT-img1.png' alt='Click to enlarge' title='Click to enlarge' width='510' height='277'/></a></p>\n<p>In 1968 MIT—and Project MAC in particular—was at the very center of emerging ideas about computer science and AI. A picture from that time captures Ed (third from left) with a few of the people involved: <a href=\"https://www.wolframalpha.com/input?i=claude+shannon\">Claude Shannon</a>, <a href=\"https://www.wolframalpha.com/input?i=john+mccarthy\">John McCarthy</a> and <a href=\"https://www.wolframalpha.com/input?i=Joseph+Weizenbaum\">Joe Weizenbaum</a> (creator of <a href=\"https://www.mentalfloss.com/posts/eliza-chatbot-history\" target=\"_blank\" rel=\"noopener\">ELIZA</a>, the original chatbot):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MIT-img2-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MIT-img2-min.png' alt='Click to enlarge' title='Click to enlarge' width='455' height='390'/></a></p>\n<p>At the end of the 1968 academic year student reviews from Ed’s course were unexpectedly good, and MIT needed faculty members who could be principal investigators on the government grants that were becoming plentiful for computing—and one of those typical-for-Ed “surprising things” happened: MIT agreed to hire him as a full professor with tenure, despite his lack of academic qualifications. It was a watershed moment for Ed, and I think a piece of validation that he carried with pride for the rest of his life. (For what it’s worth, while Ed was an extreme case, MIT was at that time also hiring at least some other people without the usual PhD qualifications into CS professor positions.) </p>\n<p>In 1971 Licklider stepped down from his position as director of Project MAC—and Ed assumed the position. His <a href=\"https://archivesspace.mit.edu/repositories/2/resources/868\" target=\"_blank\" rel=\"noopener\">archives from the time</a> contain lots of administrative material—studies, reports, proposals, budgets, etc.—including many pieces reflecting things like the birth of the ARPANET, the maturing of operating systems and the general enthusiasm about the promise of AI.</p>\n<p>One item (conceivably from an earlier time) is Ed’s summary of “Information Processing Terminology” for PDP-1 users, complete with definitions like: “A bit is a binary digit or any thing or state that represents a binary digit. Equivalently, a bit is a set with exactly two members.

Curiously—in view of all his emphasis on cellular automata—Ed doesn’t seem to have been involved.</p>\n<p>But he did do other things. In 1972, for example, as a kind of spinoff from his Problem Solving course, he <a href=\"https://medium.com/@stannenb/the-may-1972-cambridge-police-riot-731a19a52aa3\" target=\"_blank\" rel=\"noopener\">formed a group called &#8220;The Army to End the War&#8221;</a> (i.e. the Vietnam War), whose idea was that it was time to stop the government fighting an unwinnable war, and this could be achieved by having an organization that would coordinate citizens to threaten a run on banks unless the war was ended. Needless to say, though, this didn’t really fit well with the project Ed ran being funded by the Department of Defense.</p>\n<p>Between MIT being what it is, and Ed being who he was, there were often strange things that happened. As Ed tells it, one day he was in Marvin Minsky’s office talking about unrecognized geniuses, and a certain <a href=\"https://en.wikipedia.org/wiki/Patrick_Gunkel\">Patrick Gunkel</a> walks in, and identifies himself as such. Ed ended up having a long association with Gunkel, who produced such documents as:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081823MIT-img7.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081823MIT-img7.png' alt='Click to enlarge' title='Click to enlarge' width='362' height='464'/></a></p>\n<p>(Gunkel’s major goal was to create what he called <a href=\"https://ideonomy.mit.edu/\" target=\"_blank\" rel=\"noopener\">&#8220;ideonomy&#8221;, or the &#8220;science of ideas&#8221;</a>, with divisions like isology, chorology, morology and crinology. I met Gunkel once, in Woods Hole, where he had become something of a local fixture, riding around town with his cat in his bicycle basket.)</p>\n<p>But after a few years as director of Project MAC, in 1974 Ed was onto something new: being a visiting scholar at Caltech. After his 1961 encounter, he had gotten to know Richard Feynman—who always enjoyed spending time with “out of the box” people like Ed. And so in 1974 Ed went for a year to Caltech, to be with Feynman.</p>\n<h2 id=\"the-universe-as-a-cellular-automaton\">The Universe as a Cellular Automaton</h2>\n<p>My own efforts (and successes) with cellular automata may perhaps have had something to do with it. But I think at least in the later part of his life, Ed felt his greatest achievements related to cellular automata and in particular his idea that the universe is a giant cellular automaton. I’m not sure when Ed really first hatched this idea, or indeed started to think about cellular automata. Ed had told me many times that when he’d told John McCarthy “the idea”, McCarthy suggested testing it by looking for “roundoff error” in physics, analogous to roundoff error from finite precision in computers. Ed scoffed at this, accusing McCarthy of imagining that there was literally “an IBM 709 computer in the sky”. And Ed’s implication was that he had gotten further than that, imagining the universe to be made more abstractly from a cellular automaton.</p>\n<p>I didn’t know quite when this exchange with McCarthy was supposed to have taken place (and, by the way, some of the emerging experimental implications of our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> are precisely about finding evidence of discrete space through something quite analogous to “roundoff errors” in the equations for spacetime). But Ed’s implication to me was always that he’d started exploring cellular automata sometime before 1960.</p>\n<p>In the mid-1990s, researching history for my book <em>A New Kind of Science</em>, (as I’ll discuss below) I had a detailed email exchange and long phone conversation with Ed about this. The result was a statement in my <a href=\"https://www.wolframscience.com/nks/notes-2-3--history-of-cellular-automata/\">notes about the history of cellular automata</a>:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img1.png' alt='Click to enlarge' title='Click to enlarge' width='435' height='101'/></a></p>\n<p>At the time, Ed made it sound very convincing. But in writing this piece, I’ve come to the conclusion it’s almost certainly not correct. And of course that’s disappointing given all the effort I put into the history notes in my book, and the almost complete lack of other errors that have surfaced even after two decades of scrutiny. But in any case, it’s interesting to trace the actual development of Ed’s ideas. </p>\n<p>One useful piece of evidence is a 25-page document from 1969 <a href=\"https://archivesspace.mit.edu/repositories/2/resources/868\" target=\"_blank\" rel=\"noopener\">in his archives</a>, entitled “Thinking about New Things”—that seems to outline Ed’s thinking at the time. Ed explains “I am not a Physicist, in fact I know very little about modern physics”—but says he wants to suggest a new way of thinking about physics:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img2.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='521'/></a></p>\n<p>Soon he starts talking about the possibility that the universe is “merely a simulation on a giant computer”, and relates a version of what he told me about his interaction with John McCarthy:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img3-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img3-min.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='899'/></a></p>\n<p>He talks (in a rather programmer kind of way) about the beginning of the universe:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img4.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='297'/></a></p>\n<p>He goes on—again in a charmingly “programmer” way:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img5-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img5-min.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='899'/></a></p>\n<p>A bit later, Ed is beginning to get to the concept of cellular automata:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img6-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img6-min.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='807'/></a></p>\n<p>And there we have it: Ed gets to (3D) cellular automata, though he calls them “spatial automata”:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img7.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img7.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='443'/></a></p>\n<p>And now he claims that spatial automata can exhibit “very complex behavior”—although his meaning of that will turn out to be a pale shadow of what I <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-1--how-do-simple-programs-behave\">discovered in the early 1980s with things like rule 30</a>: </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img8.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img8.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='73'/></a></p>\n<p>But at this point Ed already seems to think he’s almost there—that he’s almost reproduced physics:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img9.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img9.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='237'/></a></p>\n<p>A little later he’s discussing doing something very much in my style: enumerating possible rules:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img10.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img10.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='403'/></a></p>\n<p>And still further on he actually talks about 1D rules. And in some sense it might seem like he’s getting very close to what I did in the early 1980s. But his approach is very different. He’s not doing “science” and “empirically seeing what cellular automata do”. Or even being very interested in cellular automata for their own sake. Instead, he’s trying to engineer cellular automata that can “be the universe”. And so for example he wants to consider only left-right symmetric cellular automata “because the universe is isotropic”. And having also decided he wants cellular automata that are symmetric under interchange of black and white (a property he calls “syntactic symmetry”), he ends up with just 8 rules. He could just have simulated these by running them on a computer. But instead he tries to “prove” by pure thought what the rules will do—and comes up with this table:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img11.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img11.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='349'/></a></p>\n<p>Had he done simulations he might have made pictures like these (labeled using my rule-numbering scheme):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img12.png' alt='' title='' width='558' height='180'> </div>\n</p></div>\n<p>But as it was he didn’t really come to any particular conclusion, other than what amount to a few simple “theorems” about what “data processing” these cellular automata can do:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img13.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img13.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='260'/></a></p>\n<p>I must say I find it very odd that—particularly given all the stories about his activities and achievements he told me—Ed never in the four decades I knew him mentioned anything about having thought about 1D cellular automata. Perhaps he didn’t remember, or perhaps—even after everything I wrote about them—he never really knew that I was studying 1D cellular automata.</p>\n<p>But in any case, what comes next in the 1969 document is Ed getting back to “pure thought” arguments about how cellular automata might “make physics”:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img14-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img14-min.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='937'/></a></p>\n<p>It’s a bit muddled (though, to be fair, this was a document Ed never published), but at the end it’s basically saying that if the universe really is just a cellular automaton then one should be able to replace physical experiments (that would, for example, need particle accelerators) with “digital hardware” that just runs the cellular automaton. The next section is entitled “The Design of a Simulator”, and discusses how such hardware could be constructed, concluding that a 1000×1000×1000 3D grid of cells could be built for $50M (or nearly half a billion dollars today).</p>\n<p>After that, there’s one final (perhaps unfinished) section that reads a bit like a caricature of “I’ve-got-a-theory-of-physics-too” mechanical models of physics:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img15.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img15.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='297'/></a></p>\n<p>But, OK, so what does this all mean? Well, first, I think it makes it rather clear that (despite what he told me) by 1969—let alone 1961—Ed hadn’t actually implemented or run cellular automata in any serious way. It’s also notable that in this 1969 piece Ed isn’t using the term “cellular automaton”. The <a href=\"https://www.wolframscience.com/nks/notes-2-3--history-of-cellular-automata/\">concept of cellular automata had been invented many times</a>, under many different names. But by 1969 the term “cellular automaton” was pretty firmly established, and in fact 1969 might have represented the very peak up to that point of interest in cellular automata in the world at large. But somehow Ed didn’t know about this—or at least wasn’t choosing to connect with it.</p>\n<p>Even at MIT <a href=\"https://www.genealogy.math.ndsu.nodak.edu/id.php?id=111888\" target=\"_blank\" rel=\"noopener\">Frederick Hennie</a> in the EE department had actually been <a href=\"https://archive.org/details/iterativearrayso0000fred\" target=\"_blank\" rel=\"noopener\">studying cellular automata</a>—albeit under the name “iterative arrays”—since the very beginning of the 1960s. In 1968 <a href=\"https://en.wikipedia.org/wiki/Edgar_F._Codd\" target=\"_blank\" rel=\"noopener\">E. F. Codd</a> from IBM (who laid the foundations for SQL—and who worked with Ed’s friend <a href=\"https://en.wikipedia.org/wiki/John_Cocke_(computer_scientist)\" target=\"_blank\" rel=\"noopener\">John Cocke</a>) had published a book entitled <em>Cellular Automata</em>. <a href=\"http://alvyray.com/\" target=\"_blank\" rel=\"noopener\">Alvy Ray Smith</a>—in the same department as John McCarthy at Stanford—was writing his PhD thesis on “cellular automata”. In 1969 Marvin Minsky and Seymour Papert published their <em>Perceptrons</em> book, and were apparently talking a lot about cellular automata. And for example by the fall of 1969 Papert’s student Terry Beyer had <a href=\"https://dspace.mit.edu/handle/1721.1/6881\" target=\"_blank\" rel=\"noopener\">written a thesis</a> about the “recognition and transformation of figures by iterative arrays of finite state automata”—under the auspices of Project MAC, presumably right under Ed’s nose. (And, no, the thesis doesn’t mention Ed, though it mentions Minsky.)</p>\n<p>Right around that time, though, something happens. Ed had been convinced—probably by Minsky and McCarthy—that any cellular automaton capable of “being the universe” better be computation universal. And now there’s a student named <a href=\"https://conwaylife.com/wiki/Edwin_Roger_Banks\" target=\"_blank\" rel=\"noopener\">Roger Banks </a>who’s working on seeing what kind of (2D) cellular automaton would be needed to get computation universality. Banks had found examples requiring much fewer than the 29 states von Neumann and Burks had used in the 1950s. But—as he related to me many times—Ed challenged Banks to find a 2-state example (“implementable purely with logic gates”), and Banks soon found it, first describing it in June 1970:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img16.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img16.png' alt='Click to enlarge' title='Click to enlarge' width='534' height='257'/></a></p>\n<p>Banks had apparently been interacting with the “Life hackers” at MIT, and in November 1970 some of the thunder of his result was stolen when Bill Gosper at MIT discovered the glider gun, which suggested that even the rules of the Game of Life (albeit involving 9 rather than 5 2D neighbors) were likely to be sufficient for computation universality. </p>\n<p>But for our efforts to trace history, Banks’s June 1970 report has a number of interesting elements. It relates the history of cellular automata, without any mention of Ed. But then—in its one mention of Ed—it says:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img17.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img17.png' alt='Click to enlarge' title='Click to enlarge' width='535' height='291'/></a></p>\n<p>The “mod-2 rule” that Ed told me he’d simulated in 1961 has finally made an appearance. In an oral history years later Terry Winograd <a href=\"https://conservancy.umn.edu/bitstream/handle/11299/107717/1/oh237taw.pdf\" target=\"_blank\" rel=\"noopener\">reported that in 1970</a> he “went to a lecture of Papert’s in which he described a conjecture about cellular automata [which Winograd] came back with a proof of”. </p>\n<p>By January 1971, Banks is <a href=\"http://www.bottomlayer.com/bottom/banks/banks_thesis_1971.pdf\" target=\"_blank\" rel=\"noopener\">finishing his thesis</a>, which is now officially supervised by Ed (even though it’s nominally in the mechanical engineering department):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img18.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img18.png' alt='Click to enlarge' title='Click to enlarge' width='551' height='186'/></a></p>\n<p>Most of Banks’s work is presented as what amount to “engineering drawings”, but he mentions that he has done some simulations. I don’t know if these included simulations of the mod-2 rule but it seems likely. </p>\n<p>So was 1969 or 1970 the first time the mod-2 rule had been heard from? I’m not sure, but I suspect so. But to confuse things there’s a “display hack” known as “munching squares” (described in HAKMEM) that looks in some ways similar, and that was probably already seen in 1962 on the PDP-1. Here are the frames in a small example of munching squares: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img19_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img19.png' alt='' title='' width='597' height='142'> </div>\n</p></div>\n<p>Here’s a video of a bigger example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw081923Automaton-img20_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/Munching-Squares.gif' alt='' title='' width='128' height=''> </div>\n</p></div>\n<p>I expect Ed saw munching squares, perhaps even in 1962. But it’s not the mod-2 rule—or actually a cellular automaton at all. And even though Ed certainly had the capability to simulate cellular automata back at the beginning of the 1960s (and could even have recorded videos of 2D ones with III’s film technology) the evidence we have so far is that he didn’t. And in fact my suspicion is that it was probably only around the time I met Ed in 1982 when it finally happened. </p>\n<h2 id=\"my-first-encounter-with-ed\">My First Encounter with Ed</h2>\n<p>In May 1981 there’d been a conference at MIT on the <a href=\"https://mitendicotthouse.org/physics-computation-conference/ \" target=\"_blank\" rel=\"noopener\">Physics of Computation</a>. I’d been invited, but in the end I couldn’t go—because (in a pattern that has repeated many times in my life) it coincided with the initial release of my SMP software system. Still, in December 1981 I got the following invitation:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img1.jpg\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img1.jpg' alt='Click to enlarge' title='Click to enlarge' width='620' height='1022'/></a></p>\n<p>In January 1982 I was planning to go to England to do a few weeks of intensive SMP development on a computer that a friend’s startup had—and I figured I would go to the Caribbean “on the way”. </p>\n<p>It was an interesting group that assembled on January 18, 1982, on Mosquito Island. It was the first time I met my now-longtime friend <a href=\"https://en.wikipedia.org/wiki/Gregory_Chaitin\" target=\"_blank\" rel=\"noopener\">Greg Chaitin</a>.

(Despite the promise of the invitation, Feynman’s health prevented him from coming.) And then there were people who’d worked on reversible computation, like <a href=\"https://www.informationphilosopher.com/solutions/scientists/landauer/\" target=\"_blank\" rel=\"noopener\">Rolf Landauer</a> and <a href=\"https://en.wikipedia.org/wiki/Charles_H._Bennett_(physicist)\" target=\"_blank\" rel=\"noopener\">Charles Bennett</a>.

And finally there was Ed. At first he seemed a little Gatsby-like, watching and listening, but not saying much. I think it was the next morning that Ed pulled me aside rather conspiratorially and said I should come and see something.</p>\n<p style=\"display: inline-block;float:right;padding: 0px;margin: 5px; margin-top: -6px;\"><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img2.png' alt='Click to enlarge' title='Click to enlarge' width='135' height='247'/></a></p>\n<p>There was just one real house (as opposed to cabin) on the island (with enough marble to clinch the Bond-villain-lair vibe). Ed led me to a narrow room in the house—where there was a rather-out-of-place-for-a-tropical-island modern workstation computer. I&#8217;d seen workstation computers before; in fact, the company I&#8217;d started was at the time (foolishly) thinking of building one. But the computer Ed had was from a company he was CEOing. It was a <a href=\"https://en.wikipedia.org/wiki/PERQ\" target=\"_blank\" rel=\"noopener\">PERQ 1</a>, made by <a href=\"https://en.wikipedia.org/wiki/Three_Rivers_Computer_Corporation\" target=\"_blank\" rel=\"noopener\">Three Rivers Computer Corporation</a>, which had been founded by a group from CMU including McCarthy&#8217;s former student <a href=\"https://www.wolframalpha.com/input?i=Dabbala+Rajagopal+Reddy\">Raj Reddy</a>. I learned that Three Rivers was a company in trouble, and that Ed had recently jumped in to save it. I also learned that in addition to any other challenges the engineers there might have had, he&#8217;d added the requirement that the PERQ be able to successfully operate on a tropical island with almost 100% humidity. </p>\n<p>But in any case, Ed wanted to show me something on the screen. And here’s basically what it was:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img3_copy.txt' data-c2c-type='text/html'> <video loading='lazy' height=\"auto\" width=\"256\" style=\"margin-left:0px\" muted=\"\" alt=\"\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/08/PERQ-1.mov\" autoplay=\"\" loop=\"\" playsinline><br />\n</video></div>\n</div>\n<p>Ed pressed a button and now this is what happened:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img4_copy.txt' data-c2c-type='text/html'> <video loading='lazy' height=\"auto\" width=\"256\" style=\"margin-left:0px\" muted=\"\" alt=\"\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/08/PERQ-2.mov\" autoplay=\"\" loop=\"\" playsinline><br />\n</video></div>\n</p></div>\n<p>I’d seen plenty of “display hacks” before. Bill Gosper had shown me ones at <a href=\"https://www.parc.com/about-parc/parc-history/\" target=\"_blank\" rel=\"noopener\">Xerox PARC</a> back in 1979, and my archives even contain some of the early color laser printer outputs he gave me:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img5-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img5-min.png' alt='Click to enlarge' title='Click to enlarge' width='640' height='413'/></a></p>\n<p>I don’t remember the details of what Ed said. And what I saw looked like “display hacks flashing on the screen”. But Ed also mentioned the more science-oriented idea of reversibility. And I’m pretty sure he mentioned the term “cellular automaton”. It wasn’t a long conversation. And I remember that at the end I said I’d like to understand better what he was showing me.</p>\n<p>And so it was that Ed handed me a PERQ 8” floppy disk. And now, 41 years later, here it is, sitting— still unread—in my archives:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img6.png' alt='Click to enlarge' title='Click to enlarge' width='266' height='319'/></a></p>\n<p>It’s not so easy these days to read something like this—and I’m not even sure it will have “magnetically survived”. But fortunately—along with the floppy—there’s something else Ed gave me that day. Two copies of a 9-page printout, presumably of what’s on the floppy:</p>\n<p><a img class=\"mfp-img\" alt=\"Click to enlarge\" title=\"Click to enlarge\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img7-min-min.jpeg\" style=\"max-height: auto;\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img7.png' alt='Click to enlarge' title='Click to enlarge' width='592' height='499'/></a></p>\n<p>And what’s there is basically a <a href=\"https://en.wikipedia.org/wiki/Pascal_(programming_language)\" target=\"_blank\" rel=\"noopener\">Pascal</a> program (and the PERQ was a very Pascal-oriented machine; “PERQ” is said to have stood for “Pascal Engine that Runs Quicker”). But what does the program do? The main program is called “CA1”, suggesting that, yes, it was supposed to do something with cellular automata. </p>\n<p>There are a few comments:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img8.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img8.png' alt='Click to enlarge' title='Click to enlarge' width='426' height='375'/></a></p>\n<p>And there’s code for making help text:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img9.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img9.png' alt='Click to enlarge' title='Click to enlarge' width='500' height='385'/></a></p>\n<p>Apparently you press “<span class=\"promptformatted\">b</span>” to “clear the Celluar [<em>sic</em>] Automata boundary”, “<span class=\"promptformatted\">n</span>” for “Fredkin’s Pattern” and “<span class=\"promptformatted\">p</span>” for “EF1”. And at the end there’s a reference to munching squares. The first pattern above is what you get by pressing “<span class=\"promptformatted\">n</span>”; the second by pressing “<span class=\"promptformatted\">p</span>”.</p>\n<p>Both patterns look pretty messy. But if instead you press “<span class=\"promptformatted\">a</span>”, you get something with a lot more structure:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/PERQ-3.gif' alt='' title='' width='256' height=''> </div>\n</p></div>\n<p>I think Ed showed this to me in passing. But he was more interested in the more complicated patterns, and in the fact that you could get them to reverse what they were doing. And in this animated form, I suspect this just looked to me like another munching squares kind of thing.</p>\n<p>But, OK, given that we have the program, can we tell what it actually does? The core of it is a bunch of calls to the function <span class=\"computer-voice\">rasterop()</span>. Functions like <span class=\"computer-voice\">rasterop()</span> were common in computers with bitmapped displays. Their purpose was to apply a certain Boolean operation to the array of black and white pixels in a region of the screen. Here it’s always <span class=\"computer-voice\">rasterop(6, &#8230;)</span> which means that the function being applied is Boolean function 6, or Xor (or “sum mod 2”). </p>\n<p>And what’s happening is that chunks of the screen are getting Xor’ed together: specifically, chunks that are offset by one pixel in each of the four directions. And this is all happening in two phases, swapping between different halves of the framebuffer. Here are the central parts of the sequence of frames that get generated starting from a single cell:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img11.png' alt='' title='' width='598' height='292'> </div>\n</p></div>\n<p>It helps a lot to see the separate frames explicitly. And, yes, it’s a cellular automaton. In fact, it’s exactly the “reversible mod-2 rule”. Here it is for a few more steps, with its simple “self-reproduction” increasingly evident:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img12.png' alt='' title='' width='658' height='239'> </div>\n</p></div>\n<p>Back in 1982 I think I only saw the PERQ that one time. But in one of the resort cabins on the other side of the island—there was this (as captured in a slightly blurry photograph that I took):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img13-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img13-min.png' alt='Click to enlarge' title='Click to enlarge' width='324' height='482'/></a></p>\n<p>It was a “cellular automaton machine” built out of “raw electronics” by Tom Toffoli and Norm Margolus—who were the core of Ed’s “Information Mechanics” group at MIT. It didn’t feel much like science, but more like a video DJ performance. Patterns flashing and dancing on the screen. Constant rewiring to produce new effects. I wanted to slow it all down and “sciencify” it. But Tom and Norm always wanted to show yet another strange thing they’d found.</p>\n<p>Looking in my archives today, I find just one other photograph I took of the machine. I think I considered this the most striking pattern I saw the machine produce. And, yes, presumably it’s a 2D cellular automaton—though despite my decades of experience with cellular automata I don’t today immediately recognize it:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img14-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Encounter-img14-min.png' alt='Click to enlarge' title='Click to enlarge' width='446' height='290'/></a></p>\n<p>What did I make of Ed back in 1982? Remember, those were days long before the web, and before one could readily look up people’s backgrounds. So pretty much all I knew was that Ed was connected to MIT, and that he owned the island. And I had the impression that he was some kind of technology magnate (and, yes, the island and the plane helped). But it was all quite mysterious. Ed didn’t engage much in technical conversations. He would make statements that were more like pronouncements—that sounded interesting, but were too vague and general for me to do much more than make up my own interpretations for them. Sometimes I would try to ask for clarification, but the response was usually not an explanation, but instead a tangentially related—though often rather engaging—story. </p>\n<p>All these years later, though, one particular exchange stands out in my memory. It was at the end of the conference. We were standing around in the little restaurant on the island, waiting for a boat to arrive. And Ed said out of the blue: “I’ll make a deal with you. You teach me how to write a paper and I’ll teach you how to build a company.” At the time, this struck me as quite odd. After all, writing papers seemed easy to me, and I assumed Ed was doing it if he wanted to. And I’d already successfully started a company the previous year, and didn’t think I particularly needed help with it. (Though, yes, I made plenty of mistakes with that company.) But that one comment from Ed somehow for years cemented my view of him as a business tycoon who didn’t quite “get” science, though had ideas about it and wanted to dabble in it. </p>\n<h2 id=\"ed-and-feynman\">Ed and Feynman</h2>\n<p>Ed would later describe Richard Feynman as his best friend. As we discussed above, they’d first met in 1961, and in 1974 Ed had spent the year at Caltech visiting Feynman, having, as Ed tells it, made a deal (analogous to the one he later proposed to me) that he would teach Feynman about computers, and Feynman would teach him about physics. I myself first got to know Feynman in 1978, and interacted extensively with him not only about physics, but also about symbolic computing—and cellular automata. And in retrospect I have to say I’m quite surprised that he mentioned Ed to me only a few times in passing, and never in detail.</p>\n<p>But I think the point was that Feynman and Ed were—more than anything else—personal friends. Feynman tended to find “traditional academics” quite dull, and much preferred to hang out with more “unusual” people—like Ed. Quite often the people Feynman hung out with had quite kooky ideas about things, and I think he was always a little embarrassed by this, even though he often seemed to find it fun to indulge and explore those ideas.</p>\n<p>Feynman always liked solving problems, and applying himself to different kinds of areas. But I have to say that even I was a little surprised when in writing this piece I was going through <a href=\"https://archivesspace.mit.edu/repositories/2/resources/868\" target=\"_blank\" rel=\"noopener\">the archives of Ed&#8217;s papers at MIT</a>, and found the following letter from Feynman to Ed:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img1.png' alt='Click to enlarge' title='Click to enlarge' width='474' height='495'/></a></p>\n<p>Clearly he—like me—viewed Ed as an authority on business. But what on earth was this “cutting machine”, and why was Feynman trying to sell it? </p>\n<p>For what it’s worth, the next couple of pages tell the story:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img2-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img2-min.png' alt='Click to enlarge' title='Click to enlarge' width='432' height='1046'/></a></p>\n<p>Feynman’s next-door neighbor had a company that made swimwear, and this was a machine for cutting the necessary fabric—and Feynman had helped develop it. And much as Feynman had been prepared to help his neighbor with this, he was also prepared to help Ed with some of his ideas about physics. And in the archive of Ed’s papers, there’s a letter from Feynman:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img3.png' alt='Click to enlarge' title='Click to enlarge' width='596' height='1085'/></a></p>\n<p>I don’t know whether this is the first place the term “Fredkin gate” was ever used. But what’s here is a quintessential example of Feynman diving into some new subject, doing detailed calculations (by hand) and getting a useful answer—in this case about what would become Ed’s best-known invention: reversible logic, and the Fredkin gate.</p>\n<p>Feynman had always been interested in “computing”. And indeed when he was recruited to the Manhattan Project it was to run a team of human computers (equipped with mechanical desk calculators). I think Feynman always hoped that physics would “become computational” at least in some sense—and he would for example lament to me that Feynman diagrams were such a bad way to compute things. Feynman always liked the methodology of traditional continuous mathematics, but (as I just noticed) even in 1964 he was saying that “I believe that the theory that space is continuous is wrong, because we get these infinities and other difficulties&#8230;”. And elsewhere in <a href=\" https://www.feynmanlectures.caltech.edu/messenger.html\" target=\"_blank\" rel=\"noopener\">his 1964 lectures</a> that became <em><a href=\"https://mitpress.mit.edu/9780262560030/the-character-of-physical-law/\" target=\"_blank\" rel=\"noopener\">The Character of Physical Law</a></em> Feynman says: </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img4.png' alt='Click to enlarge' title='Click to enlarge' width='412' height='311'/></a></p>\n<p>Did Feynman say these things because of his conversations with Ed? I rather doubt it. But as I was writing this piece I learned that Ed thought differently. <a href=\"https://gwern.net/doc/cs/2016-hagar.pdf\" target=\"_blank\">As he told it</a>:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I never pressed any issue that would sort of give me credit, okay? It’s just my nature. A very weird thing happened toward the end of my time at Caltech. Richard Feynman and I would get into very fierce arguments. . . . I’m trying to convince him of my ideas, that at the bottom is something finite and so on. He suddenly says to me, “You know, I’m sure I had this same idea sometime quite a while ago, but I don’t remember where or how or whether I ever wrote it down.” I said, “I know what you’re talking about. It’s a set of lectures you gave someplace. In those lectures you said perhaps the world is finite.” He just has this little statement in this book. I saw the book on his shelf. I got it out, and he was so happy to see that there. What I didn’t tell him was he gave that lecture years after I’d been haranguing him on this subject. I knew he thought it was his idea, and I left it that way. That was just my nature.</p>\n</blockquote>\n<p>Notwithstanding what he said, I rather suspect he did push the point. And for example when Feynman gave a talk on “<a href=\"https://link.springer.com/article/10.1007/BF02650179\" target=\"_blank\" rel=\"noopener\">Simulating Physics with Computers</a>” at the <a href=\"https://mitendicotthouse.org/physics-computation-conference/\" target=\"_blank\" rel=\"noopener\">1981 MIT Physics of Computation conference</a> that Ed co-organized, he was careful to write that:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Feynman-img5.png' alt='Click to enlarge' title='Click to enlarge' width='552' height='87'/></a></p>\n<p>Ed, by the way, arranged for Feynman to get his first personal computer: a Commodore PET. I don’t think Feynman ended up using it terribly much, though in 1984 he took it with him on a trip to Hawaii where he and his son Carl used it to work out probabilities to try to <a href=\"https://writings.stephenwolfram.com/2023/02/a-50-year-quest-my-personal-journey-with-the-second-law-of-thermodynamics/#where-does-randomness-come-from?\">&#8220;crack&#8221; the randomness of my rule 30 cellular automaton</a> (needless to say, without success).</p>\n<h2 id=\"digital-physics-&#038;-reversible-logic\">Digital Physics &#038; Reversible Logic</h2>\n<p>Back at MIT in 1975 after his year at Caltech, Ed was no longer the director of Project MAC, but was still on the books as a professor, albeit something of an outcast one. Soon, though, he was teaching a class about his ideas—under the title of “Digital Physics”:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img1-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img1-min.png' alt='Click to enlarge' title='Click to enlarge' width='403' height='564'/></a></p>\n<p>Cellular automata weren’t specifically mentioned in the course description—though in the syllabus they were there, with the Game of Life as a key example: </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img2.png' alt='Click to enlarge' title='Click to enlarge' width='348' height='559'/></a></p>\n<p>Back in the 1960s, cellular automata had been a popular topic in theoretical computer science. But by the mid-1970s the emphasis of the field had switched to things like computational complexity theory—and, as Ed told me many times, his efforts to interest people at MIT in cellular automata failed, with influential CS professor <a href=\"http://people.csail.mit.edu/meyer/\" target=\"_blank\">Albert Meyer</a> (whose advisor <a href=\"https://www.wolframalpha.com/input?i=patrick+carl+fischer\">Patrick Fischer</a> had worked quite extensively on cellular automata) apparently telling Ed that “one can tell someone is out of it if they don’t think cellular automata are dead”. (It’s an amusing irony that around this time, Meyer’s future wife <a href=\"http://irenegreif.com/\" target=\"_blank\">Irene Greif</a> would point <a href=\"https://www.stx.ox.ac.uk/people/john-moussouris\" target=\"_blank\">John Moussouris</a>—who we’ll meet later—to Ed and his work on cellular automata.) </p>\n<p>Ed’s ideas about physics were not well received by the physicists at MIT. And for example when students from Ed’s class asked the well-known MIT physics professor <a href=\"https://compton.mit.edu/philip-morrison\" target=\"_blank\">Philip Morrison</a> what he thought of Ed’s approach, he apparently responded that “Of course Fredkin thinks the universe is a computer—he’s a computer person; if instead he were a cheese merchant he’d think it was a big cheese!”</p>\n<p>When Ed was at Caltech in 1974 a big focus there—led by <a href=\"http://www.carvermead.caltech.edu/\" target=\"_blank\">Carver Mead</a>—was VLSI design. And this led to increasing interest in the ultimate limits on computation imposed by physics. Ever since <a href=\"https://www.wolframalpha.com/input?i=John+von+neumann\">von Neumann</a> in the 1950s it had been assumed that every step in a computation would necessarily require dissipation of energy—and this was something Carver Mead took as a given. But if this was true, how could Ed’s cellular automaton for the universe work? Somehow, Ed reasoned, it—and any computation, for that matter—had to be able to run reversibly, without dissipating any energy. And this is what led Ed to his most notable scientific contribution: the idea of <a href=\"https://www.wolframscience.com/nks/notes-10-11--reversible-logic/\">reversible logic</a>.</p>\n<p>Ordinary logic operations—like And and Or—take two bits of input and give one bit of output. And this means they can’t be reversible: with only one bit in the output there isn’t information to uniquely determine the two bits of input from the output. But if—like Ed—you consider a generalized logic operation that for example has both two inputs and two outputs, then this can be invertible, i.e. reversible.</p>\n<p>The concept of an invertible mapping had long existed in mathematics, and under the name “automorphisms of the shift” had even been studied back in the 1950s <a href=\"https://www.wolframscience.com/nks/notes-6-7--surjectivity-and-injectivity-of-cellular-automaton-maps/\">for the case of what amounted to 1D cellular automata (for applications in cryptography)</a>. And in 1973 <a href=\"http://www.nasonline.org/member-directory/members/3003901.html\" target=\"_blank\">Charles Bennett</a> had shown that one could make a reversible analog of a Turing machine. But what Ed realized is that it’s possible to make something like a typical computer design—and have it be reversible, by building it out of reversible logic elements. </p>\n<p>Looking through the archive of Ed’s papers at MIT, I found what seem to be notes on the beginning of this idea:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img3.png' alt='Click to enlarge' title='Click to enlarge' width='441' height='548'/></a></p>\n<p>And I also found this—which I immediately recognized as a <a href=\"https://www.wolframscience.com/nks/notes-12-8--sorting-networks/\">sorting network</a>, in which values get sorted through a sequence of binary comparisons:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img4.png' alt='Click to enlarge' title='Click to enlarge' width='281' height='223'/></a></p>\n<p>Sorting networks are inevitably reversible. And this particular sorting network I recognized as the largest guaranteed-optimal sorting network that’s known—discovered by Milton Green at SRI (then “Stanford Research Institute”) in 1969. It’s implausible that Ed independently discovered this exact same network, but it’s interesting that he was drawing it (by hand) on a piece of paper. </p>\n<p>Ed’s archives also contain a 3-page draft entitled “Conservative Logic”:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img5.png' alt='Click to enlarge' title='Click to enlarge' width='560' height='595'/></a></p>\n<p>Ed explains that he is limiting himself to gates that implement permutations</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img6.png' alt='Click to enlarge' title='Click to enlarge' width='560' height='112'/></a></p>\n<p>and then goes on to construct a “symmetric-majority-parity” gate—which he claims is “computation universal”:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img7.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img7.png' alt='Click to enlarge' title='Click to enlarge' width='560' height='400'/></a></p>\n<p>It’s not quite a Fredkin gate, but it’s close. And, by the way, it’s worth pointing out that these gates alone aren’t “computation universal” in something like the Turing sense. Rather, the point is that—like with Nand for ordinary logic—any reversible logic operation (i.e. permutation) with any number of inputs can be constructed using just these gates, connected by wires. </p>\n<p>Ed didn’t at first publish anything about his reversible logic idea, though he talked about it in his class, and in 1978 there were already students writing term papers about it. But then in 1978, as <a href=\"https://youtu.be/ROv1HX-gdas?t=1331 \" target=\"_blank\" rel=\"noopener\">Ed told it later</a>:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I found this guy Tommaso Toffoli. He had written a paper that showed how you could build a reversible computer by storing everything that an ordinary computer would have to forget. I had figured out how to have a reversible computer that didn’t store anything because all the fundamental activity was reversible. Okay? So I decided to hire him because he was the only person who tried to do it and he didn’t succeed, really, and I had—and I hired him to help me.</p>\n</blockquote>\n<p>Toffoli had done a first PhD in Italy building electronics for cosmic ray detectors, and in 1978 he’d just finished a second PhD, working on 2D cellular automata with Art Burks (who had coined the name “cellular automaton”). Ed brought Toffoli to MIT under a grant to build a cellular automaton machine—leading to the machine I saw on Ed’s island in 1982. But Ed also worked with Toffoli to write a paper about conservative logic—which finally appeared in 1982, and contained both the Fredkin gate, and the Toffoli gate. (Ed later griped to me that Toffoli “really hadn’t done much” for the paper—and that after all the Toffoli gate was just a special case of the Fredkin gate.)</p>\n<p>Back in 1980—on the way to this paper—Ed, with Feynman’s encouragement, had had another idea: to imagine implementing reversible logic not just abstractly, but through an explicit physical process, namely collisions between elastic billiard balls. And as we saw above, Feynman quickly got into analyzing this, for example seeing how a Fredkin gate could be implemented just with billiard balls.</p>\n<p>But ultimately Ed wanted to implement reversibility not just for things like circuits, but also—imitating the reversibility that he believed was fundamental to physics—for cellular automata. Now the fact is that reversibility for cellular automata had actually been quite well studied since the 1950s. But I don’t think Ed knew that—and so he invented his own way to “get reversibility” in cellular automata.</p>\n<p>It came from something Ed had seen on the PDP-1 back in 1961. As Ed tells it, in playing around with the PDP-1 he had come up with a piece of code that surprised him by drawing something close to a circle in pixels on the screen. Minsky had apparently “gone into the debugger” to see how it worked—and in 1972 HAKMEM attributed the algorithm to Minsky (though in the Pascal program I got from Ed in 1982, it appears as a function called <span class=\"computer-voice\">efpattern()</span>). Here’s a version of the algorithm:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img8_copy.txt' data-c2c-type='text/html'><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img8.png' alt='' title='' width='576' height=''> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082223ReversibleX-img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img9E.png' alt='' title='' width='377' height=''> </div>\n</p></div>\n<p>And, yes, with different divisors <em>d</em> it can give <a href=\"https://nbickford.wordpress.com/2011/04/03/the-minsky-circle-algorithm/\" target=\"_blank\" rel=\"noopener\">rather different</a> (and <a href=\"https://www.blurb.com/b/2172660-minskys-trinskys-3rd-edition\" target=\"_blank\" rel=\"noopener\">sometimes wild</a>) results:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082223Reversible10-img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082223Reversible10-img1.png' alt='' title='' width='632' height='227'> </div>\n</p></div>\n<p>But for our purposes here what’s important is that Ed found out that this algorithm is reversible—and he realized that in some sense the reason is that it’s based on a second-order recurrence. And, once again, the basic ideas here are well known in math (cf. reversibility of the wave equation, which is second order). But Ed had a more computational version: a <a href=\"https://www.wolframscience.com/nks/p437--the-notion-of-reversibility/\">second-order cellular automaton</a> in which one adds mod 2 the value of a cell two steps back. And I think in 1982 Ed was already talking about this “mod-2 trick”—and perhaps the PERQ program was intended to implement it (though it didn’t). </p>\n<p>Ed’s work on reversible logic and “digital physics” in a sense came to a climax with the <a href=\" https://mitendicotthouse.org/wp-content/uploads/2018/03/MIT-1981.jpg\" target=\"_blank\" rel=\"noopener\">1981 Physics of Computation conference at MIT</a>—that brought in quite a <em>Who’s Who</em> of people who’d been interested in related topics (as I mentioned above, I wasn’t there because of a clash with the release of SMP Version 1.0, though I did meet or at least correspond with most of the attendees at one time or another):</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://mitendicotthouse.org/wp-content/uploads/2018/03/MIT-1981.jpg\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img11.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img11.png' alt='Click to enlarge' title='Click to enlarge' width='598' height='418'/></a></p>\n<p>Originally Ed wanted to call the conference “Physics and Computation”. But Feynman objected, and the conference was renamed. In the end, though, Feynman gave a talk entitled “Simulating Physics with Computers”—which most notably talked about the relation between quantum mechanics and computation, and is often seen as a key impetus for the development of quantum computing. (As a small footnote to history, I worked with Feynman quite a bit on the possibility of both quantum computing and quantum randomness generation, and I think we were both convinced that the process of measurement was ultimately going to get in the way—something that with our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> we are finally now beginning to be able to <a href=\"https://writings.stephenwolfram.com/2021/04/the-wolfram-physics-project-a-one-year-update/#can-we-finally-understand-quantum-mechanics?\">analyze in much more detail</a>.)</p>\n<p>But despite his interactions with Feynman, Ed was never too much into the usual ideas of quantum mechanics, hoping (as he said in the flyer for his course on digital physics) that perhaps quantum mechanics would somehow fall out of a classical cellular-automaton-based universe. But when quantum computing finally became popular in the 1990s, reversible logic was a necessary feature, and the Fredkin gate (also known as CSWAP or “controlled-swap”) became famous. (The Toffoli gate—or CCNOT—is a bit more famous, though.)</p>\n<p>In tracing the development of Ed’s ideas, particularly about “digital physics”, there’s another event worthy of mention. In late 1969 Ed learned about an older German tech entrepreneur named Konrad Zuse who’d published an article in 1967 (and a book in 1969) on <em><a href=\"https://philpapers.org/archive/ZUSRR.pdf\" target=\"_blank\" rel=\"noopener\">Rechnender Raum (Calculating Space)</em></a>—mentioning the term “cellular automata”:</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://philpapers.org/archive/ZUSRR.pdf\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img12.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Reversible-img12.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='831'/></a></p>\n<p>Although Zuse was 24 years older than Ed, there were definitely similarities between them. Zuse had been very early to computers, apparently building one during World War II that suffered an air raid (and may yet still lie buried in Berlin). After the war, Zuse started a series of computer companies—and had ideas about many things. He’d been trained as an engineer, and perhaps it was having worked on solving his share of PDEs using finite differences that led him to the idea—a bit like Ed’s—that space might fundamentally be a discrete grid. But unlike Ed, Zuse for the most part seemed to think that—as with finite differences—the values on the grid should be continuous, or at least integers. Ed arranged for Zuse’s book to be translated into English, and for Zuse to visit MIT. I don’t know how much influence Zuse had on Ed, and when Ed talked to me about Zuse it was mostly just to say that people had treated his ideas—like Ed’s—as rather kooky. (I exchanged letters with Zuse in the 1980s and 1990s; he seemed to find my work on cellular automata interesting.)</p>\n<h2 id=\"ideas-&#038;-inventions-galore\">Ideas &#038; Inventions Galore</h2>\n<p>It wasn’t just physics that Ed had ideas about. It was lots of other things too. Sometimes the ideas would turn into businesses; more often they’d just stay as ideas. Ed’s archive, for example, contains a document on the “Intermon Idea” that Ed hoped would “provide a permanent solution to the world’s problem of not having a stable medium of exchange”:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Inventions-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Inventions-img1.png' alt='Click to enlarge' title='Click to enlarge' width='518' height='632'/></a></p>\n<p>And, no, Ed wasn’t Satoshi Nakamoto—though he did tell me several times that (although, to his displeasure, it was never acknowledged) he had suggested to Ron Rivest (the “R” of RSA cryptography) the idea of “using factoring as a trapdoor”. And—not content with solving the financial problems of the world, or, for that matter, fundamental physics—Ed also had his “algorithmic plan” to prevent the possibility of World War III.</p>\n<p>And then there was the Muse. Marvin Minsky had long been involved with music, and had assembled out of electronic modules a system that generated sequences of musical notes. But in 1970 Ed and Minsky developed what they called the Muse—whose idea was to be a streamlined system that would use integrated circuits to “<a href=\"https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/3610801\" target=\"_blank\" rel=\"noopener\">automatically compose music</a>”:</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://120years.net/the-triadex-muse-edward-fredkin-marvin-minsky-usa-1971/\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Inventions-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Inventions-img2.png' alt='Click to enlarge' title='Click to enlarge' width='640' height='443'/></a></p>\n<p>In actuality, the Muse produced sequences of notes determined by a <a href=\"https://writings.stephenwolfram.com/2016/05/solomon-golomb-19322016/\">linear feedback shift register</a>—in essence a 1D additive cellular automaton—in which the details of the rule were set on its front panel as “themes”. The results were <a href=\"https://www.youtube.com/watch?v=YZVyl8HkxWU\" target=\"_blank\" rel=\"noopener\">interesting—if rather R2-D2-like</a>—but weren’t what people usually thought of as “music”. Ed and Minsky started a company named Triadex (note the triangular shape of the Muse), and manufactured a few hundred Muses. But the venture was not a commercial success. </p>\n<p>Particularly through interacting with Minsky, Ed was quite involved in “things that should be possible with AI”. The Muse had been about music. But Ed also for example thought about chess—where he wanted to build an array of circuits that could tree out possible moves. Working with Richard Greenblatt (who had developed an earlier chess machine) my longtime friend John Moussouris ended up designing <a href=\"https://www.chessprogramming.org/CHEOPS\" target=\"_blank\" rel=\"noopener\">CHEOPS (a &#8220;Chess-Oriented Processing System&#8221;)</a> while Ed was away at Caltech. (Soon thereafter, curiously enough, Moussouris would go to Oxford and work with Roger Penrose on discrete spacetime—in the form of spin networks. Then in later years he would found two important Silicon Valley microprocessor companies.)</p>\n<p>Keeping on the chess theme, Ed would in 1980 (through his Fredkin Foundation) put up the Fredkin Prize for the first computer to beat a world champion at chess. The first “pre-prize” of $5k was awarded in 1981; the second pre-prize of $10k in 1988—and the grand prize of $100k was <a href=\"https://archive.nytimes.com/www.nytimes.com/library/cyber/week/073097chess.html\" target=\"_blank\" rel=\"noopener\">awarded in 1997 with some fanfare</a> to the IBM Deep Blue team. </p>\n<p>Ed also put up a prize for “math AI”, or, more specifically, automated theorem proving. It was <a href=\"https://www.ams.org/prizes-awards/paview.cgi?parent_id=5\" target=\"_blank\" rel=\"noopener\">administered through the American Math Society</a> and a few “milestone prizes” were given out. But the grand Leibniz Prize “for the proof of a ‘substantial’ theorem in which the computer played a major role” was never claimed, the assets of the Fredkin Foundation withered, and the prize was withdrawn. (I wonder if some of the things done in the 1980s and 1990s by users of Mathematica should have qualified—but Ed and I never made this connection, and it’s too late now.) </p>\n<h2 id=\"ed-the-consultant\">Ed the Consultant</h2>\n<p>Particularly during his time at MIT, Ed did a fair amount of strategy consulting for tech companies—and Ed would tell me many stories about this, particularly related to IBM and DEC (which were in the 1980s the world’s two largest computer companies).</p>\n<p>One story (whose accuracy I’ve never been able to determine) related to DEC’s ultimately disastrous decision not to enter the personal computer business. As Ed tells it, a team at DEC did a focus group about PCs—with Ken Olsen (CEO of DEC) watching. There was a young teacher in the group who was particularly enthusiastic. And Olsen seemed to be getting convinced that, yes, PCs were a good idea. As the focus group was concluding, the teacher listed off all sorts of ways PCs could change the world. But then, fatefully, he added right at the end: “And I don’t just mean here on Earth”. Ed claims this was the moment when Olsen decided to kill the PC project at DEC.</p>\n<p>Ed told a story from the early 1970s about a giant IBM project called FS (for “Future Systems”):</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">IBM has this project. They’re going to completely revolutionize everything. The project is to design everything from the smallest computer to the new largest. They’re all to be multiprocessors. The specs were just fantastic. They promised to guarantee their customers 100% uptime. Their plans were, for instance, when you have a new OS, it’s updated. They guarantee 24-hour operation at all times. They plan to be able to update the OS without stopping this process. Things like that, a lot of goals that are very lofty, and so on.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Someone at IBM whom I knew very well, a very senior guy, came to me one day and said, “Look, these guys are in trouble, and maybe MIT could help them.” I organized something. Just under 30 professors of computer science came down to IBM. We got there on Sunday night and starting Monday morning, we got one lecture an hour, eight on Monday, Tuesday, Wednesday, Thursday, and four on Friday, describing the system. It was just spectacular, everything they were trying to do, but it was full of all kinds of idiocy. They were designing things that they’d never used. This whole thing was to be oriented about people looking at displays.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">No one at IBM had done anything like that. They think, “Okay, you should have a computer display,” and they came up with certain problems that hadn’t occurred to the rest of us. If you’re looking at the display, how can you tell the difference between what you had put into the computer and what the computer had put in? This worried them. They came up with a hardware fix. When you typed, it always went on the right half of the screen; when the computer did something, it always went on the left half, or I may have it backwards, but that was the hardware.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">&#8230;</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">What happened is I came to realize that they were so over their head in their goal that they were going to annihilate themselves with this thing. It was just going to be the world’s greatest fiasco for it. I started cornering people and saying, “Look, do you realize that you’re never going to make this work?” and so on, so forth. This came to the attention of people at IBM, and it annoyed them. I got a call from someone saying, “Look, you’re driving us nuts. We want to hear you out, so we’re going to conduct a debate.” There’s a guy named Bob [Evans], who was the head of the project. What happened was we’re in the boardroom with IBM, lots of officials there, and he and I have a debate.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I’m debating that they have to kill the project and do something else. He’s debating that they shouldn’t kill the project. I made all my points. He made all his points. Then a guy named <a href=\"https://en.wikipedia.org/wiki/Emanuel_R._Piore\" target=\"_blank\" rel=\"noopener\">Mannie Piore</a>, who was the one who thought of the idea of having a research laboratory, a very senior guy said to me, he said, “Hey, Ed,” he said, “We’ve heard you out.” He says, “This is our company. We can do this product even if you think we shouldn’t.” I said, “Yes, I admit that’s true.” He said, “You presented your case. We’ve heard you out, and we want to do it.” I said, “Okay.” He said, “Can you do us a favor?” I said, “What’s that?’ He said, “Can you stop going around talking to people about why it has to be killed?” I said, &#8220;Look, I’ve said my piece. I’ve been heard out.” “Yes. Okay.” “I quit.” </p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I had only one ally in that room; that was John Cocke. As we were walking out of the room, he came over to me and said, “Don’t worry, Ed.” He said, “It’s going to fall over of its own weight.” I’ll never forget that. Ten days later, it was canceled. A lot of people were very mad at me.</p>\n</blockquote>\n<p>I’m not sure what Ed was like as an operational manager of businesses. But he certainly had no shortage of opinions about how businesses should be run, or at least what their strategies should be. He was always keen on “do-the-big-thing” ideas. I remember him telling me multiple times about a company that did airplane navigation. It had put a certain number of radio navigation beacons into its software. Ed told me he’d asked about others, and the company had said “Well, we only put in the beacons lots of people care about”. Ed said “Just put all of them in”. They didn’t. And eventually they were overtaken by a company that did.</p>\n<h2 id=\"ed-the-businessman\">Ed the Businessman</h2>\n<p>Ed’s great business success—and windfall—was III. But Ed was also involved with a couple dozen other companies—almost all of which failed. There’s a certain charm in the diversity of Ed’s companies. There was Three Rivers Computer Corporation, that made the PERQ computer. There was Triadex, that made the Muse. There was a Boston television station. There was an air taxi service. There was Fredkin Enterprises, importing PCs into the Soviet Union. There was Drake’s Anchorage, the resort on his island. There was Gensym, a maker of AI-oriented process control systems, which was a rare success. And then there was Reliable Water.</p>\n<p>Ed’s island—like many tropical islands—had trouble getting fresh water. So Ed decided to invent a solution, coming up with a new, more energy-optimized way to do reverse osmosis—with a dash of AI control. Reliable Water announced its product in May 1987, desalinating water taken from Boston Harbor and serving it to journalists to drink. (Ed told me he was a little surprised how willingly they did so.)</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://timesmachine.nytimes.com/timesmachine/1987/05/13/328387.html?pageNumber=102\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img1.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='460'/></a></p>\n<p>Looking at my archives I see I was sufficiently charmed by the picture of Ed posing with his elaborate “intelligent” glass tubing that I kept the article from <em>New Scientist</em>:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img2-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img2-min.png' alt='Click to enlarge' title='Click to enlarge' width='400' height='323'/></a></p>\n<p>As Ed told it to me, Reliable Water was just about to sell a major system to an Arab country when his well-pedigreed CEO somehow cheated him, and the deal fell through.</p>\n<p>But what about the television station? How did Ed get involved with that? Apparently in 1969 Jerry Wiesner, then president of MIT, encouraged Ed to support a group of Black investors (led by a certain Bertram Lee) who were challenging the broadcasting license of Boston’s channel 7. Years went by, other suitors showed up, and litigation about the license went all the way to the Supreme Court (which described the previous licensee as having shown an “egregious lack of candor” with the FCC). For a while it seemed like channel 7 might just “go dark”. But in early January 1982 (just a couple of weeks before I first met him) Ed took over as president of New England Television Corporation (NETV)—and in May 1982 NETV took over channel 7, leaving Ed with a foot of acquisition documents in his home library, and a television channel to run:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img3.png' alt='Click to enlarge' title='Click to enlarge' width='288' height='348'/></a></p>\n<p>There’d been hopes of injecting new ideas, and adding innovative educational and other content. But things didn’t go well and it wasn’t long before Ed stepped down from his role. </p>\n<p>A major influence on Ed’s business activities came out of something that happened in his personal life. In 1977 Ed had been married for 20 years and had three almost-grown children. But <a href=\"https://www.youtube.com/watch?v=WEDKKjRGeOU\" target=\"_blank\" rel=\"noopener\">then he met Joyce</a>. On a flight back from the Caribbean he sat next to a certain Joyce Wheatley who came from a prominent family in the British Virgin Islands and had just graduated with a BS in economics and finance from Bentley College (now Bentley University) in Waltham, MA. As both Ed and Joyce tell it, Ed immediately gave advice like that the best way to overcome a fear of flying was to learn to fly (which much later, Joyce in fact did). </p>\n<p>Joyce was starting work at a bank in Boston, but matters with Ed intervened, and in 1980 the two of them were married in the Virgin Islands, with Feynman serving as Ed’s best man (and at the last minute lending Ed a tie for the occasion). In 1981, Ed and Joyce had a son, who they named Richard after Richard Feynman (though now themed as “Rick”)—of whom Ed was very proud.</p>\n<p>When Ed died, Joyce and he had been married for 43 years—and Joyce had been Ed’s key business partner all that time. They made many investments together. Sometimes it’d start with a friend or vendor. Sometimes Ed (or Joyce) would meet students or others—who’d be invited over to the house some evening, and leave with a check. Sometimes the investments would be fairly hands-off. Sometimes Ed would get deeply involved, even at times playing CEO (as he did with Three Rivers and NETV).</p>\n<p>When the web started to take off, Ed and Joyce created a company called Capital Technologies which did angel investing—and ended up investing in many companies with names like Sourcecraft, SqueePlay, EchoMail, Individual Inc. and Radnet. And—like so many startups of this kind—most failed.</p>\n<p>Ed also continued to have all sorts of ideas of his own, some of which turned into patents. And—like so much to do with Ed—they were eclectic. In 1995 (with a couple of other people) there was one based on using evanescent waves (essentially photon tunneling) to more accurately find the distance between the read/write head and the disk in a disk drive or CD-ROM drive. Then in 1999 there was the “<a href=\"https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/6237647\" target=\"_blank\" rel=\"noopener\">Automatic Refueling Station</a>”—using machine vision plus a car database to automate pumping gas into cars:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img4.png' alt='Click to enlarge' title='Click to enlarge' width='291' height='242'/></a></p>\n<p>That was followed in 2003 by a patent about securely controlling telephone switching from web clients. In 2006, there was a patent application named simply “<a href=\"https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/20070118471\" target=\"_blank\" rel=\"noopener\">Contract System</a>” about an “algorithmic contract system” in which the requirements of buyers and sellers of basically anything would be matched up in a kind of tiling-oriented geometrical way:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img5.png' alt='Click to enlarge' title='Click to enlarge' width='312' height='160'/></a></p>\n<p>In 2011 there was “<a href=\"https://image-ppubs.uspto.gov/dirsearch-public/print/downloadPdf/20120068858\" target=\"_blank\" rel=\"noopener\">Traffic Negotiation System</a>”, in which cars would have rather-airplane-like displays installed that would get them in effect to “drive in formation” to avoid traffic jams:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Businessman-img6.png' alt='Click to enlarge' title='Click to enlarge' width='345' height='205'/></a></p>\n<p>Ed’s last patent was filed in 2015, and was essentially for a scheme to cache large chunks of the web locally on a user’s computer—a kind of local CDN.</p>\n<p>But all these patents represented only a small part of Ed’s “idea output”. And for example Ed told me many other tech ideas he had—a few of which I’ll mention later. </p>\n<p>And Ed’s business activities weren’t limited to tech. He did his share of real-estate transactions too. And then there was his island. For years Joyce and Ed continued to operate Drake’s Anchorage, and tried to improve the infrastructure of the island—with Ed, as Joyce tells it, more often to be found helping to fix the generator on the island than partaking of its beaches. </p>\n<p>Back in 1978 Ed had acquired a “neighbor” when Richard Branson bought Necker Island, which was a couple of miles further out towards the Atlantic than Moskito Island. Ed told me quite a few stories about Branson, and for years had told me that Branson wanted to buy his island. Ed hadn’t been interested in selling, but eventually agreed to give Branson right of first refusal. Then in 2007 a Czech (or were they a Russian?) showed up and offered to buy the island for cash “to be delivered in a suitcase”. It was all rather sketchy, but Ed and Joyce decided it was finally time to sell, and let Branson exercise his right of first refusal, and buy the island for about $10M.</p>\n<h2 id=\"ed-and-his-toys\">Ed and His Toys</h2>\n<p>Ed liked to buy things. Computers. Cars. Planes. Boats. Oh, and extra houses too (Vermont, Martha’s Vineyard, Portola Valley, &#8230;)—as well as his island. Ed would typically make decisions quickly. A house he drove by. New tech when it first came out. He was always proud of being an early adopter, and he’d often talk almost conspiratorially about the “secret” features he’d figured out in new tech he’d bought. </p>\n<p>But I think Ed&#8217;s all-time favorite &#8220;toys&#8221; were planes—and over the course of his life he owned a long sequence of them. Ed was a serious (and, by all reports, exceptionally good) pilot—with an airplane transport pilot license (plus seaplane and glider licenses). And I always suspected that his cut-and-dried approach to many things reflected his experience in making decisions as a pilot. </p>\n<p>Ed at different times had a variety of kinds of planes, usually registered with the vanity tail number N1EF. There were twin-propellor planes. There were high-performance single-propellor planes. There was the seaplane that I’d “met” in the Caribbean. At one time there was a jet—and in typical fashion Ed got himself certified to fly the jet singlehandedly, without a copilot. Ed had all sorts of stories about flying. About running into Tom Watson (CEO of IBM) who was also a pilot. About getting a new type of plane where he thought he was getting #5 off the production line, but it was actually #1—and one day its engine basically melted down, but Ed was still able to land it. </p>\n<p>Ed also had gliders, and competed in gliding competitions. Several times he told me a story—as a kind of allegory—about another pilot in a gliding competition. Gliders are usually transported with their wings removed, with the wings attached in order to fly. Apparently there was an extra locking pin used, which the other pilot decided to remove to save weight, because it didn’t seem necessary. But when the glider was flying in the competition its wings fell off. (The pilot had a parachute, but landed embarrassed.) The very pilot-oriented moral as far as Ed was concerned: just because you don’t understand why something is there, don’t assume it’s not necessary. </p>\n<h2 id=\"ed-and-the-soviet-union\">Ed and the Soviet Union</h2>\n<p>One of the topics about which Ed often told “you-can’t-make-this-stuff-up” stories was the Soviet Union. Ed’s friend John McCarthy had parents who were active communists, had learned Russian, and regularly took trips to the Soviet Union. And as Ed tells it McCarthy came to Ed one day and said (perhaps as a result of having gotten involved with a Russian woman) “I’m moving to the Soviet Union”, and talked about how he was planning to dramatically renounce his US citizenship. McCarthy began to make arrangements. Ed tried to talk him out of it. And then it was 1968 and the Soviets send their tanks into Czechoslovakia—and McCarthy is incensed, and according to Ed, sends a telegram to a very senior person in the Soviet Union saying “If you invade Czechoslovakia then I’m not coming”. Needless to say, the Soviets ignored him. Ed told me he’d said at the time: “If the Russians were really smart and really understood things, and they had to choose between John McCarthy and Czechoslovakia, they should have chosen John McCarthy.” (McCarthy would later “flip” and become a staunch conservative.) </p>\n<p>Perhaps through McCarthy, Ed started visiting the Soviet Union. He didn’t like the tourist arrangements (required to be through the government’s Intourist organization)—and decided to try to do something about it, sending a survey to Americans who’d visited the Soviet Union:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img1.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img1.png' alt='Click to enlarge' title='Click to enlarge' width='417' height='526'/></a></p>\n<p>A year later, Ed was back in the Soviet Union, attending a somewhat all-star conference (along with McCarthy) on AI—with a rather modern-sounding collection of topics:</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://stacks.stanford.edu/file/druid:vs238wj4745/vs238wj4745.pdf\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img2.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='643'/></a></p>\n<p>Here’s a photograph of a bearded Ed in action there—with a very Soviet simultaneous translation booth behind him:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img3-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img3-min.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='372'/></a></p>\n<p>Ed used to tell a story about Soviet computers that probably came from that visit. The Soviet Union had made a copy of an IBM mainframe computer—labeling it as a “RYAD” computer. There was a big demo—and the computer didn’t work. The generals in charge asked “Well, did you copy everything?” As it turned out, there was active circuitry in the “IBM” logo—and that needed to be copied too. Or at least that’s what Ed told me.</p>\n<p>But Ed’s most significant interaction with the Soviet Union came in the early 1980s. The US had in place its <a href=\"https://en.wikipedia.org/wiki/Coordinating_Committee_for_Multilateral_Export_Controls\" target=\"_blank\" rel=\"noopener\">CoCom list</a> that embargoed export of things like personal computers to the Soviet Union. Meanwhile, within the Soviet Union, photocopiers were strictly controlled—to prevent non-state-sanctioned flow of information. But as Ed tells it, he hatched a plan and sold it to the Reagan administration, telling them: “You’re on the wrong track. If we can get personal computers into the Soviet Union, it breaks their lock on the flow of information.” But the problem was he had to convince the Soviets they wanted personal computers.</p>\n<p>In 1984 Ed was in Moscow—supposedly tagging along to a physics conference with an MIT physicist named <a href=\"https://news.mit.edu/2023/roman-jackiw-giant-theoretical-physics-dies-0620\" target=\"_blank\" rel=\"noopener\">Roman Jackiw</a>. He “dropped in” at the Computation Center of the Academy of Sciences (which, secretly, was a supplier to the KGB of things like speech recognition tech). And there he was told to talk to a certain <a href=\"https://sdgs.un.org/panelists/he-mr-evgeny-p-velikhov-29414\" target=\"_blank\" rel=\"noopener\">Evgeny Velikhov</a>, a nuclear physicist who’d just been elected vice president of the Academy of Sciences. Velikhov arranged for Ed to give a talk at the Kremlin to pitch the importance of computers, which apparently he successfully did, after convincing the audience that his motivation was to make the world a safer place by balancing the technical capabilities of East and West.</p>\n<p>And as if to back up this point, while he was in the Soviet Union, Ed wrote a 5-page piece from “A Concerned Citizen, Planet Earth” addressed “To whom it may concern” in Moscow and Washington—ending with the suggestion that its plan might be discussed at an upcoming meeting between Andrei Gromyko and Ronald Reagan at the UN:</p>\n<p><a class=\"magnific image sourced\" data-url=\"https://www.reaganlibrary.gov/public/digitallibrary/smof/nsc-europeanandsovietaffairs/matlock/box-026/40-351-7452065-026-001-2018.pdf\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img4.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img4.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='906'/></a></p>\n<p>The piece mentions another issue: the fate of prominent, but by then dissident, Soviet physicist <a href=\"https://www.wolframalpha.com/input?i=Andrei+Sakharov\">Andrei Sakharov</a>, who was in internal exile and reportedly on hunger strike. Ed hatched a kind of PCs-for-Sakharov plan in which the Soviets would get PCs if they freed Sakharov. </p>\n<p>Meanwhile, in true arms-dealer-like fashion, he’d established Fredkin Enterprises, S.A. which planned to export PCs to the Soviet Union. He had his student Norm Margolus spend a summer analyzing the CoCom regulations to see what characteristics PCs needed to have to avoid embargo.</p>\n<p>In the Reagan Presidential Library there’s now a fairly extensive file entitled “<a href=\"https://www.reaganlibrary.gov/public/digitallibrary/smof/nsc-europeanandsovietaffairs/matlock/box-026/40-351-7452065-026-001-2018.pdf\" target=\"_blank\" rel=\"noopener\">Fredkin Computer Exports to USSR</a>”—which for example contains a memo reporting a call made on August 25, 1984, by then-vice-president George H. W. Bush to Sakharov’s stepdaughter, who was by that time living in Massachusetts (and, yes, Ed was described as a “PhD in computer science” with a “flourishing computer business”): </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img5.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img5.png' alt='Click to enlarge' title='Click to enlarge' width='621' height='456'/></a></p>\n<p>Soon the White House is communicating with the US embassy in Moscow to get a message to Ed:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img6.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img6.png' alt='Click to enlarge' title='Click to enlarge' width='621' height='534'/></a></p>\n<p>And things are quickly starting to sound as if they were from a Cold War spy drama (there’s no evidence Ed was ever officially involved with the US intelligence services, though):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img7.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img7.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='418'/></a></p>\n<p>I don’t think Ed ever ended up talking to Sakharov, but on November 6, 1984, Fredkin Enterprises was sent a letter by Velikhov ordering 100 PCs for the Academy of Sciences, and saying they hoped to order 10,000 more. But the US was not as speedy, and in 1985 there was still back and forth about CoCom issues. Ed of course had a plan:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img8-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082023Soviet-img8-min.png' alt='' title='' width='621' height='710'/></a></p>\n<p>And indeed in the end Ed did succeed in shipping at least some computers to the Soviet Union, adding a hack to support Cyrillic characters. Ed often took his family with him to Moscow, and he told me that his son Rick created quite a stir when at age 6 he was seen there playing a game on a computer. Up to then, computers had always been viewed as expensive tools for adults. But after Rick’s example there were suddenly all sorts of academicians’ kids using computers.</p>\n<p>(In the small world that it is, one person Ed got to know in the Academy of Sciences was a certain <a href=\"https://www.svod.org/arkady-borkovsky/\" target=\"_blank\" rel=\"noopener\">Arkady Borkovsky</a>—who in 1989 would leave Russia to come work at our company, and who would later co-found Yandex.)</p>\n<p>By the way, to fill in a little color of the time, I might relate a story of my own. In 1987 I went to a (rather Soviet) conference in Moscow on “Logic, Methodology and Philosophy of Science.” Like everyone, I was assigned a “guide”. Mine continually tried to pump me for information about the American computer industry. Eventually I just said: “So what do you actually want to know?” He said: “We’ve cloned the Intel 8086 microprocessor, and we want to know if it’s worth cloning the Motorola 68000. Motorola has put a layer of epoxy that makes it hard to reverse engineer.” He assumed that the epoxy was at the request of the US government, to defeat Soviet efforts—and he didn’t believe me when I said I thought it was much more likely there to defeat Intel. </p>\n<p>Ed told me another story about his interactions with Soviet computer efforts after Gorbachev came to power:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Before the days of integrated circuits the way IBM and Digital built computers was they put the whole computer together, and then it would sit for six weeks in “system integration” while they made the pieces work together and slowly got the bugs out. </p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">The Russians built computers differently because that seemed logical to them. They’d send all the components down there and then some guy was supposed to plug them together, and they were supposed to work. But they didn’t. With these big computers, they never made any of them work.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">The Academy of Sciences had one. And one time I went to see their big computer, so they unlock the doors to this dusty room where the computer is, where it’s not being used because it doesn’t work, and all this information is being kept secret, not from the United States, but from the leadership. When I discovered all this I documented it &#8230; and I wrote a 40-page document that explained it.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I was making trips with Rick often and Mike [his older son] very often. On one trip when I arrived, they tell me, “Oh, you have to come to this meeting.”</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I don’t speak Russian. I never knew it. I’m seated at this meeting, and there’s a Russian friend of mine [head of the Soviet Space Research Institute] next to me. We’re just sitting there, and things are going on. I still don’t know what that meeting was, but I had this 40-page document. I gave it to my friend. He starts reading. He says, “Oh, this is so interesting.” It got to be about ten o’clock at night and they said, “Everyone come back in the morning. Nine o’clock.”</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">My friend said, “Can I borrow this [document]? I’ll bring it back in the morning”. I said, “Sure, go ahead.” He comes back next morning. He says to me, “I have good news, and I have bad news.” I said, “What’s the good news?” He says, “Your document has been translated into Russian.” I said, “You left here with a 40-page typewritten document. I don’t believe you.” He said, “Well, my institute recently took on the task of translating scientific American into Russian.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">“When I left here, I went to my institute, called in the translators, and they all came in. We divided the document up between them, and it’s all been translated into Russian.”</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">The document was the analysis of the RYAD situation with the recommendation that the only thing they could do was to cancel it all.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I said, “Okay, what’s the bad news?” He says, “The bad news is it’s classified secret.” When you made a copy or did something, you had to have a government person look at it. They classified it. I said to him, “You can’t classify my documents.” He said, “Of course not. We haven’t. It’s just the Russian one that’s secret.”</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Then maybe a week later, he said, “Gorbachev’s read your document.” He canceled it. RYAD. Some people I know were looking to kill me.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">In Moscow, there’s a building that’s so unusual. It’s on a highway leading into the city. It’s about five stories high. It’s about a kilometer long, okay? It’s a giant building. I was in it a few years ago, and it’s just a beehive of startups, almost all software startups. That was the RYAD Software Center, okay? 100,000 people got put out of work.</p>\n</blockquote>\n<h2 id=\"ed-becomes-a-physics-professor\">Ed Becomes a Physics Professor</h2>\n<p>When I first met Ed in 1982, he was in principle a professor at MIT. But he was also CEOing a computer company (Three Rivers), and, though I didn’t know it at the time, had just become president of a television channel. Not to mention a host of other assorted business activities. MIT had a policy that professors could do other things “one day a week”. But Ed was doing other things a lot more than that. Ed used to say he was “tricked” out of his tenured professorship. Because in 1986 he was convinced that with all the other things he had going on, he should become an adjunct professor. But apparently he didn’t realize that tenure doesn’t apply to adjunct professors. And, as Ed told it, the people in the department considered him something of a kook, and without tenure forcing them to keep him, were keen to eject him.</p>\n<p>Minsky’s neighbor in Brookline, MA, was a certain Larry Sulak—the very energetic chairman of the physics department at Boston University (and someone I have known since the 1970s). Ed knew Sulak and when Ed was ejected from MIT, Sulak seized the opportunity to bring Ed in as a physics professor at Boston University. Sulak asked me to write a letter about Ed (and, yes, particularly after the research for this piece, there are some things I would change today):</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Re: Ed Fredkin</div>\n<div><span>Date:</span> Aug 24, 1988</div>\n<div><span>From:</span> Stephen Wolfram</div>\n<div><span>To:</span> Larry Sulak</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nDear Larry:</p>\n<p>In this century, people like Ed Fredkin have been very rare. Ed Fredkin<br />\nis a gentleman scientist. He has made several fortunes in business, yet<br />\nhe chooses to spend much of his time thinking about science.</p>\n<p>The main thing he thinks about is what ideas from computing can tell us<br />\nabout physics. This is an area that I believe has fundamental importance<br />\nfor physics. There are many issues about the behaviour of complex<br />\nphysical systems where the best hope for analysis and understanding comes<br />\nfrom computational ideas. There are also many traditional problems<br />\nin quantum physics and other fundamental areas that I suspect are most<br />\nlikely to be solved by thinking about things from a computational point<br />\nof view.</p>\n<p>Ed Fredkin has had some very good ideas about physics and its relation<br />\nto computation. Probably the single most important was his independent discovery<br />\nof the possibility of thermodynamically reversible computation.<br />\nvon Neumann got this wrong &#8212; by thinking about things from a computational<br />\npoint of view, Fredkin got it right.</p>\n<p>Fredkin has been convinced for many years that cellular automata &#8212;<br />\nbasically computational models &#8212; could describe fundamental physical<br />\nprocesses. As you know, I have worked on using cellular automata to<br />\nmodel various specific physical processes. Fredkin is trying to do something<br />\ngrander &#8212; he wants to show that all of physics can be reproduced by<br />\na cellular automaton. If he is right the discovery would be one whose<br />\nimportance could be compared to the discovery of quantization.<br />\nOf course, what he is trying to show may not be true, but that is a risk<br />\nthat any new fundamental idea in physics faces.</p>\n<p>Ed Fredkin&#8217;s style is not typical of scientists. He is more used to<br />\naddressing boards of directors than lecture audiences. He learned<br />\nthe kind of physics that is in the Feynman lectures by spending time<br />\nwith Dick Feynman rather than reading his books. To some standard<br />\nscientists, Fredkin at first seems like a nut. To be sure, some of his<br />\nideas are pretty nutty. But if you listen and think about it, there<br />\nis much substance to what Fredkin has to say. </p>\n<p>I gather that Fredkin has decided to spend some time around &#8220;ordinary<br />\nphysicists&#8221;, to try and work out how his ideas fit in with current<br />\nphysical thinking. I believe you are very lucky that Fredkin wants<br />\nto do this in your department. </p>\n<p>Best wishes,<br />\nStephen</p>\n</div>\n</div>\n<p></body></html></p>\n<p>And so it was that Ed became a research professor of physics at Boston University (BU). At MIT he’d gotten a DARPA grant that supported Tom Toffoli and Ed’s only “physics PhD student” Norm Margolus in building ever-larger “cellular automaton machines”. And when Ed moved to BU, this effort moved with him, leaving in effect “no trace of Ed” at MIT.</p>\n<p>When Ed arrived at BU he found he was assigned to an office with a certain <a href=\"https://www.wolframalpha.com/input?i=Gerard+%27t+Hooft\">Gerard &#8216;t Hooft</a>—who happens to be one of the more creative and productive theoretical physicists of the past half-century (and would win a Nobel Prize in 1999 for his efforts). Ed became friends with ‘t Hooft, inviting him and his family to spend time on his island, and later on the boat that Ed bought in the south of France. Feynman died in 1988, and Ed would tell me that he thought he’d “traded” one great physicist for another. (Feynman had suggested Ed try <a href=\"https://www.wolframalpha.com/input?i=sidney+coleman\">Sidney Coleman</a>, but Coleman wasn’t into it.)</p>\n<p>Like Feynman, I think ‘t Hooft felt a little uneasy with Ed’s statements about physics. But in 2016 ‘t Hooft ended up publishing a book entitled <em><a href=\"https://arxiv.org/abs/1405.1548\" target=\"_blank\" rel=\"noopener\">The Cellular Automaton Interpretation of Quantum Mechanics</a></em>. I thought it was a nice recognition of ‘t Hooft’s friendship with Ed. But Ed told me in no uncertain terms that he thought ‘t Hooft hadn’t given him the credit he was due—though in reality I don’t think what ‘t Hooft did was much related to Ed’s actual work and ideas. (And, by the way, it’s not directly related to my efforts either, though conceivably looking at <a href=\"https://www.wolframphysics.org/technical-introduction/the-updating-process-for-string-substitution-systems/generational-evolution/#p-294\" target=\"_blank\" rel=\"noopener\">&#8220;generational states&#8221; in our Physics Project</a> may give something at least somewhat analogous.)</p>\n<p>In 1994 Ed’s direct affiliation with BU ended—though he remained on good terms with the department, and after I moved to the Boston area in 2002 I would often see him at an annual dinner the BU physics department put on for “Boston-area physics people”.</p>\n<p>In 1998 Ed would summarize himself like this:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">Ed Fredkin has worked with a number of companies in the computer field and has held academic positions at a number of universities. He is a computer programmer, a pilot, advisor to businesses and an amatuer [<em>sic</em>] physicist. His main interests concern digital computer like models of basic processes in physics.</p>\n</blockquote>\n<p>For a while, Ed didn’t have a “university affiliation” (except, through Minsky, as a visitor at the MIT Media Lab), but in 2003—through his friend Raj Reddy—he became a professor (now of computer science) at Carnegie Mellon University, for a while spending time at their West Coast outpost, but mostly just making occasional trips in his plane to Pittsburgh. </p>\n<h2 id=\"forty-years-of-interactions-with-ed\">Forty Years of Interactions with Ed</h2>\n<p>For a few years after I first met Ed in 1982, I’d see him fairly regularly. In 1983 I invited him to the first “modern” conference on cellular automata, that I co-organized at Los Alamos. I visited his house in Brookline, MA, a few times. I saw him at the Aspen Center for Physics, and at other places around the world. He was always fun and lively—and told great stories about all sorts of things. He gave the impression that he was mostly spending his time doing big things in business, and that science was an avocation for him. Sometimes he would talk about cellular automata—though I now realize that what he said was either very general and philosophical (leaving me to interpret things in my own way), or very specific to particular rules he’d engineered.</p>\n<p>It was always a bit uncomfortable when it came to physics. Because the things Ed was saying always seemed to me pretty naive. Quite often I would challenge them—and frustratedly tell Ed that he should learn twentieth-century physics. But Ed would glide over it—and be off telling some other (engaging) story, or some such. </p>\n<p>In 1986 I co-organized (with Tom Toffoli and Charles Bennett) a conference called <em>Cellular Automata ’86—</em>at MIT. Ed didn’t come—and I think I had the impression that he’d rather lost interest in cellular automata by that time. I myself went off to start my Center for Complex Systems Research, and then to found Wolfram Research and start the development of Mathematica. Mathematica was released on June 23, 1988—and our records (yes, we’ve kept them!) show that Ed registered his first copy on December 14, 1988. In March 1991 I did a lecture tour about Mathematica 2.0, and saw Ed one last time before diving into work on my book <em>A New Kind of Science—</em>which led me for more than a decade to became an almost complete scientific hermit.</p>\n<p>I saw Ed (now 62 years old) when I briefly “came up for air” in connection with the release of Mathematica 3.0 in 1996, and we continued occasionally to exchange pleasant emails:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Date:</span> Sun, 29 Jun 1997 15:49:41 -0400</div>\n<div><span>From:</span> Ed Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\n&#8230;</p>\n<p>[Reporting the birth of my second child]</p>\n<p>&#8230;</p>\n<p>For many children its worst when they are teenagers.

I thought it a bit odd in 1999 when I heard that in such an encounter he said that he was the one who had “introduced me to cellular automata”. And, moreover, that he, Feynman and Murray [Gell-Mann] were the people who’d suggested I write SMP—which was particularly bizarre since, among other things, I hadn’t met (or even heard of) Ed until about 3 years later.</p>\n<p>Then, out of the blue on September 13, 2000, Ed calls my assistant, and follows up with an email:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Invitation</div>\n<div><span>Date:</span> Wed, 13 Sep 2000 23:53:09 -0400</div>\n<div><span>From:</span> Ed Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nHi,</p>\n<p>The primary reason I&#8217;m contacting you has to do with a program I&#8217;m<br />\norganizing at Carnegie Mellon (CMU).

The idea is to invite a number (8<br />\nto 10) of guests to come to CMU for a few days, to meet with students and to<br />\ngive a Distinguished Lecture. The NSF would also like to arrange for the<br />\nguests to come to Washington D.C. and give the same lecture there.</p>\n<p>By &#8220;Digital Perspective&#8221; I mean looking at aspects of the world as Digital<br />\nProcesses.

Of course, CMU will pay<br />\nexpenses and an honorarium. If the timing works out, it can probably be<br />\narranged for many of the students to have read your book before you come.<br />\nYou might get some good feedback from bright students who have also gained<br />\nfamiliarity with the thoughts of others who are thinking about the &#8220;Digital<br />\nPerspective&#8221;.

My guess is that mine is nowhere as ambitious as<br />\nyours&#8230; It&#8217;s just to document my ideas about Digital Mechanics (Physics).<br />\nIn any case, these ideas have made more progress in the last 2 years than in<br />\nthe previous 40.</p>\n<p>I bought a sailboat which is moored in Antibes, France. I spent most of the<br />\nsummer there and got more science done than in the prior several years.<br />\nIt&#8217;s absolutely the perfect place and circumstance for me to work on my<br />\nstuff. Gerard &#8216;t Hooft (plus wife and daughter) came down and joined us for<br />\na while. You know (I hope) about his interest in CA&#8217;s? I&#8217;m going back<br />\nthere for a few weeks on Tuesday.</p>\n<p>Here&#8217;s a formal proof that you can, at any time, escape all your normal<br />\nresponsibilities and concentrate exclusively on one really important thing<br />\n(hint, hint). The proof is that, at any time, YOU CAN DIE. I don&#8217;t mean to<br />\nbe morbid, but sometimes it makes good sense to consider that proof and<br />\ntemporarily abandon all but some very important task (or some very exciting<br />\nor fun thing).\n</p></div>\n</div>\n<p></body></html></p>\n<p>Ed continued with a long response to my “history questionnaire”:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\"></div>\n<div class=\"emailbody\"><span class=\"emailitalic emailgray\">&gt; 1. As far as you know, did you invent the 2D XOR CA rule? (I&#8217;m assuming<br />\n&gt; the answer is &#8220;yes&#8221;&#8230;)</span></p>\n<p>Yes, as far as I know I did invent it. Here is what I did. I decided to<br />\nlook for the simplest possible rule that met certain criteria. I wanted<br />\nspatial symmetry and a symmetric rule vis-à-vis the states of the cells.<br />\nThe thought was to find something so simple that its behavior could be<br />\nunderstood while not so simple as to be totally dull. The first such rule I<br />\ntried was the XOR rule. I programmed it first on the PDP-1 (1961, at BBN<br />\nand III) where I could see it on the display, and later I wrote a program<br />\nfor CTSS using a model 33 teletype as a terminal. My motivation was then,<br />\nas it is now, to be able to capture more and more properties of physics<br />\nwithin a Digital model. I found an easy proof as to why patterns reappeared<br />\nin any number of dimensions. I also found, at the beginning, a formula for<br />\nthe number of ones as a function of time from a single one as the initial<br />\nstate. My recollection was that it was something like 2D 2^b(t) where D is<br />\nthe number of dimensions, t is the time step, and b(t) is the number of bits<br />\nthat are one in the binary representation of t (the tally function). After<br />\nI showed all this to Seymour Papert, he generalized the proof re self<br />\nreplication from XOR (sum mod 2) to sum mod any prime. (Some time around<br />\n1967)</p>\n<p><span class=\"emailitalic emailgray\">&gt; 2. In what year did you first simulate this CA? On what computer?</span></p>\n<p>Where?</p>\n<p>See above.</p>\n<p><span class=\"emailitalic emailgray\">&gt; 3. What other CA rules did you study at that time?</span></p>\n<p>I found a simple proof that a von Neumann neighborhood CA could exactly<br />\nemulate any other (such as the 3&#215;3 neighborhood) and used this as a reason<br />\nto look at nothing else. I explored so many different rules that I probably<br />\nwould have found the game of Life had I not put blinders on. After I came<br />\nto MIT (1968), I had 2 things in mind, to find a really simple Universal CA<br />\n(I call them UCA&#8217;s )and to find Reversible, Universal CA&#8217;s (RUCA&#8217;s)<br />\nAs you may know, the search for UCA&#8217;s went slowly until I had the idea to<br />\nabandon the Turing Machine model and look at modeling digital logic and<br />\nwires. Within 15 minutes after this idea occurred to me, I had a 4 state<br />\nUCA on my blackboard. At that time the best known was in Codd&#8217;s thesis; an<br />\n8 state UCA. I showed this to a student of mine, Roger Banks, who had been<br />\nstruggling for a few years trying to complete an AI PhD thesis. The next<br />\nmorning both he and I showed up with 3 state UCA&#8217;s. He switched his PhD topic<br />\nand found a 2 state, von Neumann neighborhood UCA, a thing that Codd<br />\npurported to have proved impossible.</p>\n<p>While at BBN, after seeing all my 2-D CA&#8217;s expanding with simple<br />\nkaleidoscope like symmetries, (like the diamond shapes in the XOR rule),<br />\nMarvin Minsky challenged me to find a rule (any rule) that showed spherical<br />\npropagation. I took the challenge and shortly came up with such a rule.</p>\n<p>With respect to reversibility, the first satisfactory RUCA was done by<br />\nNorman Margolus. I shortly thereafter found a simple RUCA that didn&#8217;t need<br />\nthe use of the Margolus Neighborhood trick.</p>\n<p><span class=\"emailitalic emailgray\">&gt; 4. Do you still have any material from the simulations you did<br />\n&gt; (printouts, tapes, programs, etc.)?</span></p>\n<p>Yes, Probably, quite a bit</p>\n<p><span class=\"emailitalic emailgray\">&gt; 5. When you learn about the &#8220;munching squares&#8221; display hack? How did it<br />\n&gt; relate to your work on the XOR CA?</span></p>\n<p>I don&#8217;t recall it having any effect. It&#8217;s very unlikely that I knew of it<br />\nprior to the XOR CA.</p>\n<p><span class=\"emailitalic emailgray\">&gt; 6. What did you know about the work done by Unger etc. on cellular image<br />\n&gt; processors? How did this relate to your work?</span></p>\n<p>I knew of it second hand, but I don&#8217;t think it had any effect. Do you know<br />\nabout Farley and Clark (Wes Clark) and their publication while at MIT&#8217;s<br />\nLincoln Labs in the late 50&#8217;s?</p>\n<p><span class=\"emailitalic emailgray\">&gt; 7. What did you know about von Neumann&#8217;s work on cellular automata? How<br />\n&gt; did it relate to your work?</span></p>\n<p>At the time I did the XOR work I had not read anything about the von Neumann<br />\nCA, but I was told about it and I understood the concept very well. Many<br />\nyears later I read something (by Burkes, I think). I remember knowing that<br />\nit was a 29 state system and that it knew left from right in order to extend<br />\nand turn its construction arm.</p>\n<p><span class=\"emailitalic emailgray\">&gt; 8. What did you know about Ulam and others&#8217; work at Los Alamos on<br />\n&gt; simulating cellular automata? How did it relate to your work?</span></p>\n<p>All I knew about Ulam and CA is that, like the Hydrogen Bomb, he had key<br />\nideas but probably didn&#8217;t get as much credit as he deserved. All my<br />\nknowledge re Ulam was anecdotal. As to what he did vs. what von Neumann did<br />\nI didn&#8217;t really know anything.<br />\nI didn&#8217;t know anything about anyone else actually simulating CA&#8217;s however<br />\nI&#8217;m pretty sure I assumed that others must have done so. It was so easy and<br />\nso obvious. While the use of a computer with a display (such as the Lincoln<br />\nLab TX-0 and TX-2, the Digital PDP-1 and the IBM 709 and 7090 all had or<br />\ncould have CRT displays, it was easy enough to display simple CA&#8217;s with a<br />\nprinter, even a 10 CPS teletype.</p>\n<p><span class=\"emailitalic emailgray\">&gt; 9. Were you aware of work on cryptographic applications of CA-like<br />\n&gt; systems?</span></p>\n<p>I thought I invented that idea! As soon as I found ways to make RUCA&#8217;s it<br />\noccurred to me that they could be used for cryptography. As an aside, when<br />\nWitt Diffey [Whit Diffie] came up with the idea of public key cryptography,<br />\nwhich needed a trapdoor function, I thought of using the product of 2 large primes.<br />\nI had just written the first program, in LISP, to implement Michael Rabin&#8217;s first<br />\nversion of a probabilistic prime test. As soon as I implemented it I<br />\nstarted a search at 10^100 and discovered that 10^100 +35,737 and 10^100<br />\n+35,739 were prime. A week later I met Rich Schroeppel in LA (he was<br />\nworking for my company, III) and knowing a larger prime pair than anyone<br />\nelse on Earth I told Rich and he was blown away. He was seated at a PDP-10<br />\nterminal and all he said was an emphatic &#8220;Really!&#8221; He then went type, type,<br />\ntype for a few seconds and turned around and said &#8220;You&#8217;re right!&#8221; which blew<br />\nme away! I asked what he did and he said (while knowing nothing of Rabin&#8217;s<br />\nmethod) &#8220;all I did was look at 3^(n-1) mod n, you know, Fermat&#8217;s little<br />\ntheorem, it usually gives 1 for primes.&#8221;</p>\n<p>I&#8217;m rambling, probably about stuff of no interest to you. Anyway, I stopped<br />\nRon Rivest in the hallway at Tech Square and asked if he had heard of<br />\nDiffey&#8217;s [Diffie&#8217;s] stuff. I don&#8217;t remember exactly what he said but I know that when<br />\nI told him that Rabin&#8217;s new method to find large primes meant that the<br />\nproduct of 2 primes was a good trapdoor function he was surprised and<br />\nthought it was a good idea! I never thought any more about it and hadn&#8217;t<br />\ncome up with the idea of using the phi function&#8230; Years later, long after<br />\nRSA was a big thing Ron reminded me of the event&#8230; Don Knuth told me that<br />\nhe also thought of using the product of 2 primes before RSA, but he couldn&#8217;t<br />\nhave known about Rabin&#8217;s method when I did (as Rabin told it to me right<br />\nwhen he thought it up!)</p>\n<p>By the way, I have an interesting algorithm for factoring smaller numbers,<br />\nsuch as can be done in less than an hour with Mathematica (normal<br />\nFactorInteger or ECM). I&#8217;ve written a few terribly unoptimized Mathematica<br />\nfunctions that implement the method. For what its good for, my Mathematica<br />\nfunctions (not compiled or anything) make Mathematica factor in a lot less<br />\nreal time than Mathematica does with FactorInteger or ECM.</p>\n<p>The big news re me and my work is what&#8217;s happening right now. Whatever one<br />\nthinks about my stuff (Digital Mechanics), it&#8217;s vastly improved. However<br />\nit&#8217;s still very far from a complete theory. Of course, Digital Mechanics is<br />\nabout CA&#8217;s.</p>\n<p>If you have any interest in reversibility, I&#8217;ve done lots in that area,<br />\nranging from RUCAs, conservative logic, and my transforms. The transforms<br />\nare general methods of converting algorithms that calculate the approximate<br />\ntime evolution of a system (approximate because of round off, truncation and<br />\nthe finite delta t) which is approximately reversible (by changing delta t<br />\nto minus delta t) into an equivalent algorithm that calculates approximately<br />\nthe same thing going forwards, but which is exactly reversible (being<br />\ncalculated on a computer with round off and truncation error). I also have<br />\na lot of methods for making RUCA&#8217;s with particular properties.</p>\n<p>You&#8217;ve criticized me in the past for not publishing stuff, but I&#8217;m so<br />\nambitious as to what I&#8217;m trying to do that I haven&#8217;t had the motivation to<br />\npublish all the little things I&#8217;ve uncovered along the way.</p>\n<p>I&#8217;m sure I discovered more and better ways to make all kinds of RUCAs before<br />\nanyone else with the exception of the rule found by my student, Margolus.</p>\n<p>Finally, one last anecdote. You and I were at some meeting long ago (maybe<br />\nSanta Fe?) and you brought along an early Sun to demonstrate your collection<br />\nof different kinds of 1-D CA&#8217;s. After your talk, I asked you why none of<br />\nthe CA&#8217;s you showed were reversible. Your response was &#8220;Because all<br />\nreversible CA&#8217;s are trivial.&#8221; That really was a very common belief,<br />\ncoincident with most people&#8217;s intuition. On the spot, I made up a rule,<br />\nusing your convention for specifying it, of an &#8220;interesting&#8221; reversible CA.<br />\nYou typed it in and ran it. Being surprised is one of the best kinds of<br />\nexperiences we ever have.</p>\n<p>As Emerson once quipped, &#8220;My apologies for such a long email, I didn&#8217;t have<br />\nthe time to write you a short one.&#8221;</p>\n<p>I&#8217;m having fun; it&#8217;s a good thing to do!</p>\n<p>Best regards</p>\n<p>Ed F</p>\n<p>PS If you have any interest in having parts of your book read so that you<br />\ncan get comments prior to publication, I have an idea that might be useful.</p></div>\n</div>\n<p></body></html></p>\n<p>A little later he added:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> error</div>\n<div><span>Date:</span> Fri, 15 Sep 2000 10:12:15 -0400</div>\n<div><span>From:</span> Ed Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nHi,</p>\n<p>Looking at my long email I noticed a boo boo.</p>\n<p>Where I wrote, quoting Schroeppel talking about 3^(n-1) mod n, &#8220;&#8230;it<br />\nusually give a 1 for primes&#8230;&#8221; very true but a bit of an understatement.<br />\nOf course, it ALWAYS gives a 1 for primes! What Schroeppel said was that it<br />\nusually doesn&#8217;t give a 1 for non-primes.

As far as you know, did you invent the 2D XOR CA rule?<br />\n&gt;&gt;</span><br />\n<span class=\"emailgray\">&gt; Yes, as far as I know I did invent it. Here is what I did. &#8230;.<br />\n&gt;</span></p>\n<p>Very interesting.</p>\n<p>1a. Did you ever look at 1D CAs? If not, why not?</p>\n<p>1b. Did you think about analogies between XOR rules and linear feedback<br />\nshift registers?</p>\n<p>1c. Did you think about analogies between XOR rules and Pascal&#8217;s<br />\ntriangle?</p>\n<p>By the way, the result about the number of binomial coefficients mod a<br />\nprime has been independently discovered a remarkable number of times<br />\n(including by me). The earliest references I know are Edouard Lucas<br />\n(1877) and James Glaisher (1899).</p>\n<p>&#8230;.</p>\n<p><span class=\"emailitalic emailgray\">&gt;&gt; 3. What other CA rules did you study at that time?</span></p>\n<p><span class=\"emailgray\">&gt; &#8230; I explored so many different rules that I probably<br />\nwould have found the game of Life had I not put blinders on.</p>\n<p></span>By the way, I happened to have a long phone conversation recently with<br />\nJohn Conway about the history of the Game of Life. I still haven&#8217;t<br />\nquite got to the bottom of exactly what Conway was doing and why (I<br />\nthink he wants some of the history lost, which is a pity, because it is<br />\ninteresting and reflects much better on him than he seems to<br />\nbelieve&#8230;) But what is clear is that Conway (and his various helpers)<br />\nhad much more serious motivations from recursive function theory etc.<br />\nthan is ever usually mentioned. It was just not a &#8220;find an amusing<br />\ngame&#8221; etc. piece of work.</p>\n<p><span class=\"emailgray\">&gt; Marvin Minsky challenged me to find a rule (any rule) that showed spherical<br />\npropagation. I took the challenge and shortly came up with such a rule.</span></p>\n<p>I don&#8217;t believe I&#8217;ve ever seen your rule of this kind. I showed such a<br />\nrule to Marvin in 1984 and he said &#8220;that&#8217;s very interesting; we were<br />\nlooking for these but hadn&#8217;t found any&#8221;. So I&#8217;m confused about<br />\nthis&#8230;.</p>\n<p>&#8230;</p>\n<p><span class=\"emailitalic emailgray\">&gt;&gt; 6. What did you know about the work done by Unger etc. on cellular image<br />\nprocessors? How did this relate to your work?</span></p>\n<p><span class=\"emailgray\">&gt; I knew of it second hand, but I don&#8217;t think it had any effect.</span></p>\n<p>Wasn&#8217;t BBN quite involved with cellular image processing? And I believe<br />\nyou worked on aerial photography analysis. Did you use cellular<br />\nautomata for image processing?</p>\n<p>&#8230;</p>\n<p><span class=\"emailitalic emailgray\">&gt;&gt; 9. Were you aware of work on cryptographic applications of CA-like<br />\nsystems?</span></p>\n<p><span class=\"emailgray\">&gt; I thought I invented that idea!</span></p>\n<p>There was a lot of work done on 1D CAs by some distinguished<br />\nmathematicians consulting for the NSA in the late 1950s. I think much<br />\nof it is still classified. But over the years I&#8217;ve talked to many of<br />\nthe people involved (Gustav Hedlund, Andrew Gleason, John Milnor, some<br />\nNSA folk, etc. etc.), and read their unclassified papers. They figured<br />\nout some interesting stuff. They thought of it as related to nonlinear<br />\nfeedback shift registers.</p>\n<p><span class=\"emailgray\">&gt; As soon as I found ways to make RUCA&#8217;s it<br />\noccurred to me that they could be used for cryptography.</span></p>\n<p>How?</p>\n<p>There&#8217;s a 1D CA (rule 30) that I studied in 1984 that has been<br />\nextensively used as a randomness generator (e.g. Random[Integer] in<br />\nMathematica uses it), and that has been used a bit as a cryptosystem.</p>\n<p>I tried to make a good public key system out of CAs in the mid-1980s<br />\n(mostly in collaboration with John Milnor), but did not come up with<br />\nanything satisfactory. &#8230;</p>\n<p>&#8230;</p>\n<p><span class=\"emailgray\">&gt; I also have a lot of methods for making RUCA&#8217;s with particular properties.</span></p>\n<p>I am definitely somewhat interested in these things. They don&#8217;t happen<br />\nto be central to my grand scheme. But they are obviously worthwhile &#8230;<br />\nAND WORTH (you) WRITING DOWN!!</p>\n<p><span class=\"emailgray\">I&#8217;m sure I discovered more and better ways to make all kinds of RUCAs before<br />\nanyone else with the exception of the rule found by my student, Margolus.</span></p>\n<p>Interesting. You probably know that the general problem of telling<br />\nwhether an arbitrary 2D CA is reversible is undecidable (the question<br />\ncan be mapped to the tiling problem).</p>\n<p>So I&#8217;m taking it that you have some good methods for generating 2D<br />\nreversible CAs. That&#8217;s obviously interesting.</p>\n<p><span class=\"emailgray\">&gt; Finally, one last anecdote. &#8230; I asked you why none of<br />\nthe CA&#8217;s you showed were reversible. Your response was &#8220;Because all<br />\nreversible CA&#8217;s are trivial.&#8221; &#8230;</span></p>\n<p>This anecdote can&#8217;t be quite right. I have known since 1982 that there<br />\nare nontrivial things that can happen in CAs that are made reversible by<br />\nyour mod 2 trick. What is true (and may have been what I was saying)<br />\nis that none of the 2-color nearest neighbor CAs that are reversible are<br />\nnon-trivial. With more colors or more neighbors, that changes. I&#8217;m<br />\nguessing that what you showed me was a 4-color nearest neighbor CA that<br />\nis reversible &#8230; and that is of course quite easy to get by recoding a<br />\n2-color one that has your mod 2 trick.</p>\n<p>By the way, I heard third hand a while back that you had &#8220;introduced me<br />\nto CAs&#8221;. For what it&#8217;s worth, that isn&#8217;t correct. My first &#8220;CA<br />\nexperience&#8221; was actually in 1973 (when I was 13) when I tried to program<br />\nmolecular dynamics on a very small computer, and ended up with something<br />\nequivalent to the square CA fluid model. My next CA experience was in<br />\nsummer 1981. I was trying to make models of &#8220;self organizing&#8221; systems<br />\n(now I hate that term), particularly self-gravitating gases. I ended up<br />\nsimplifying the models until I got 1D CAs. That fall I spent a month at<br />\nthe Institute for Advanced Study, and spent a lot of time studying von<br />\nNeumann&#8217;s work, etc., and analysing all sorts of features of 1D CAs. I<br />\ncame for a day to give a talk at MIT, and was having dinner with some<br />\nLCS people (Rich Zippel was one of them), and they told me about your<br />\nwork. Later that fall I talked with Feynman a certain amount about what<br />\nI was doing with CAs, and he again mentioned you. (I think he had been<br />\nto your Physics of Computation meeting, which was perhaps in June 1981,<br />\nbut I didn&#8217;t discuss the CA aspects of the meeting with him.) Then in<br />\n[January 1982] I came to the meeting you had on your island, and Tom Toffoli<br />\nshowed me his 2D CA machine (at the time he gave me the impression of<br />\n95% hackery, 5% science), and you showed me the 2D XOR CA on a PERQ<br />\ncomputer.\n</p></div>\n</div>\n<p></body></html></p>\n<p>Ed didn’t respond to this, but three days later we talked on the phone. I sent some (unvarnished) notes from the call to a research assistant of mine:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Fredkin conversation</div>\n<div><span>Date:</span> Sat, 23 Sep 2000 03:05:43 -0500</div>\n<div><span>From:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nI had a long conversation with Ed this evening.</p>\n<p>About his work in science, my work in science, etc.</p>\n<p>A few things mentioned:</p>\n<p>&#8211; He feels bitter that his paper on reversible logic, coauthored with<br />\nTom Toffoli, was actually all his (Ed&#8217;s) work</p>\n<p>&#8211; He is pleased that I will discuss history even when people haven&#8217;t<br />\npublished things (of course he has published little)</p>\n<p>&#8211; He says he has written about 150 pages about his views of physics; he<br />\nis planning to prepare something, perhaps for publication, in about a<br />\nyear</p>\n<p>&#8211; He says he missed not being able to bounce ideas off Dick Feynman &#8230;<br />\neven though Feynman often ended up screaming at him (Ed) about how dumb<br />\nhis ideas were</p>\n<p>&#8211; He said that his main problem was that he has been trying to get<br />\npeople to steal his ideas for years, but nobody was interested</p>\n<p>&#8211; He said that now &#8220;for some reason&#8221; he is becoming more concerned about<br />\nmatters of credit</p>\n<p>&#8211; He is a serious fan of Mathematica, the Mathematica Book, etc.</p>\n<p>&#8211; He made an effort again (he&#8217;s been trying for 20 years) to get me to<br />\ncoauthor a paper with him. He recognizes that he can&#8217;t write a credible<br />\nscientific paper, but he&#8217;s &#8220;sure he has some ideas I haven&#8217;t thought<br />\nof&#8221;. I told him that unfortunately I haven&#8217;t written a paper for 15<br />\nyears.</p>\n<p>&#8211; I told him that particularly when I&#8217;m in the Boston area, I&#8217;ll look<br />\nforward to chatting with him about physics etc.</p>\n<p>&#8211; He said he&#8217;s tried to interact some with Gerhardt &#8216;t Hooft, but that<br />\n&#8216;t Hooft keeps on rushing off in traditional physics directions that Ed<br />\n(and I, by the way) think are stupid</p>\n<p>&#8211; He wanted to know if I really believed that all of physics etc. was<br />\nultimately discrete; he expressed the opinion that he and I may be the<br />\nonly people in the world who actually believe that right now</p>\n<p>&#8211; He told a bizarre story about how Don Knuth gave a talk at MIT<br />\nrecently on computers and religion, and how 1/4 of it was stuff that Don<br />\nhad heard about from Ed. Apparently Guy Steele asked a question about<br />\nhow Don&#8217;s stuff related to Ed&#8217;s, and Don said something meaningless.</p>\n<p>I talked to him a little more about the CA history stuff. He mentioned<br />\nthat around 1961 a certain Henry Stommel (sp?) told him that CA-like<br />\nmodels had been used in studying sand dunes in the 1930s. I have a<br />\nfeeling this may be another cat gut search, but perhaps we can follow<br />\nup. (You could email Ed at the appropriate time.)</p>\n<p>I asked Ed if he had ever looked at cryptography (as in NSA style stuff)<br />\nwith CAs. He said no. But that in the late 1960&#8217;s he had had a student<br />\nwho had studied ways to make counters out of JK flip flops &#8230; and that<br />\nthat person&#8217;s work had made something that Ed thought could be used for<br />\ncryptography. This was followed up by a certain Vera Pless<br />\nsubsequently.</p>\n</div>\n</div>\n<p></body></html></p>\n<p>I didn’t hear anything more from Ed for a while, though a public records search indicates that, yes, he had successfully “worked the system” to <a href=\"https://www.nsf.gov/awardsearch/showAward?AWD_ID=0001796\" target=\"_blank\" rel=\"noopener\">get $100k from the NSF for &#8220;The Digital Perspective Project”</a>. And on May 1, 2001, I received a rather formal email from Ed (for some reason Americans born before about 1955 seem to reflexively call me “Steve”):</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Workshop on the Digital Perspective 24-26 July, Washington DC</div>\n<div><span>Date:</span> Tue, 1 May 2001 21:20:45 -0400</div>\n<div><span>From:</span> Ed Fredkin</div>\n<div><span>To:</span> Steve Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nWe are sending this email to invite you to an NSF-sponsored workshop on the<br />\nDigital Perspective in Physics planned for July 24th through the 26th,<br />\nTuesday, Wednesday and Thursday.

We intend to<br />\ncombine the papers presented at the workshop into a monograph that will be<br />\npublished later this year. Two earlier workshops on related subjects were<br />\nheld at Moskito Island and this was a central theme at a meeting held at<br />\nMIT&#8217;s Endicott house in 1982.

Nearly a month passed with no word from Ed, so I pinged him asking what was going on. No response. It was a very busy time for me, and this wasn’t something I wanted to be chasing (I saw myself as doing Ed a favor by suggesting sending people to his workshop) &#8230; so I sent a slightly exasperated email:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> your conference, again</div>\n<div><span>Date:</span> Fri, 15 Jun 2001 06:08:39 -0500</div>\n<div><span>From:</span> Stephen Wolfram</div>\n<div><span>To:</span> Ed Fredkin</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nLook &#8230; I&#8217;m now in a bit of an embarrassing situation: following your<br />\ninitial response, I told David Hillman and David Reiss about your conference<br />\n&#8230; assuming you&#8217;d want to invite them &#8230; and they both became quite<br />\ninterested in it. But they never heard from anyone about it. So now of<br />\ncourse they&#8217;re wondering what&#8217;s going on. And so am I. What should I tell<br />\nthem? I&#8217;m now embarrassed about having suggested this&#8230;</p>\n<p>This seems peculiarly un-you-like. I was thinking you must have been away<br />\nor something. But isn&#8217;t the conference coming up very soon?</p>\n<p>I hope everything&#8217;s OK&#8230;\n</p></div>\n</div>\n<p></body></html></p>\n<p>Still no response from Ed. A week later I called him, and we talked for two hours. It wasn’t clear why he hadn’t already reached out to the people I’d suggested, but he quickly said he would. And then Ed launched into telling me about the “astounding” cellular automaton models he said he’d just created that “had charge, energy, momentum, angular momentum, etc.”. He talked about things like the idea of what he called an “infoton” that would be an “information particle” that would “make Feynman diagrams reversible”. I explained why that didn’t make any real sense given how Feynman diagrams actually work. It was the same kind of conversation I had many times with Ed. I kept trying to explain what was known in physics, and he kept on coming back with things that, yes, I think I understood, but that seemed close to typical crackpot fare to me. But Ed seemed convinced he had discovered something great (though exactly what I couldn’t divine). And eventually—having obviously not convinced me of what he was doing “on its merits”—he just came out and said “It must be related to stuff you’re doing, one way or another”. </p>\n<p>I explained that I really didn’t think that was very likely, not least because I emphatically wasn’t trying to use cellular automata as models of fundamental physics. And with that, Ed launched into a long speech about giving credit, particularly to him. I explained that I was trying hard to write correct history, and reiterated some of the questions I’d asked him before. He didn’t really tell me more, but instead regaled me with stories (that I’d mostly heard many times before from him) about how he’d been the first to figure out this and that—apparently oblivious to historical research I tried to tell him. But eventually we both had to go—and the conversation ended pleasantly enough, with him confirming the email addresses for the two people for his workshop. </p>\n<p>As the workshop approached, the people from my team had made arrangements to go to Washington, DC—but still didn’t know where exactly the workshop was. With days to go, one of them simply called Ed to ask. But Ed told them that actually they couldn’t come, because “Raj Reddy says there is no room for you”. Really? No extra chair to be found? Ed was the organizer, wasn’t he? Why was he laying this on someone else? It seemed to me that Ed was playing some kind of game. But at that moment I was too busy trying to finish my book to think about it. (Now that I’m writing this piece, however, I realize that Ed was perhaps following an “algorithm” he’d established years earlier when he was proud to have organized a meeting to push forward his ideas about timesharing—by inviting just people who supported his ideas, and not inviting ones who didn’t. I don’t know if the meeting actually happened, or what went on there. I don’t think the writeup promised in the invitation and in the NSF contract ever materialized.)</p>\n<p>In January 2002 <em>A New Kind of Science</em> was off to the printer, and review copies were starting to be sent out. In late March a seasoned journalist named Steven Levy (who had written about my work on cellular automata in the mid-1980s) was talking to someone from my team and reported that Ed had told him that “Minsky had told [Ed] to publish his stuff on the web to stake out priority&#8221; before my book came out. (And it’s a pity Ed didn’t do that, because it might have made it clear to him and everyone else how different what he was saying was from what I was saying.) But in any case Levy said that Ed seemed to be saying the same things as he’d said 15 years ago—and Levy knew that regardless of anything else I’d done incredibly much more since then.</p>\n<p>After his conversation with Levy, Ed sent me mail:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> The Book</div>\n<div><span>Date:</span> Fri, 22 Mar 2002 16:38:29 -0800 (PST)</div>\n<div><span>From:</span> Ed Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nCongratulations on finishing!!!</p>\n<p>I ordered the book from someplace, so long ago I can&#8217;t<br />\nremember from who.

(The person with the most mentions overall was Alan Turing, at 19; Minsky had 13; Feynman 10.) </p>\n<p>Ed never told me he’d received the book. And I’m not sure he ever seriously looked at it. But somehow he was convinced that since he knew it talked a lot about cellular automata, and had a section about physics, it must be about his big idea—that the universe is a cellular automaton. As one witty friend pointed out to me in connection with writing this piece, my book says only one thing about the universe being a cellular automaton: that it isn’t! But in any case, Ed apparently seemed to feel that I was stealing credit from him for his big idea—and, as I now realize, started an urgent campaign to right the perceived wrong, basically by telling people that somehow (despite all my efforts to describe the history) I wasn’t giving anyone enough credit and that “he was there first”. The <em>New York Times</em> rather diplomatically quoted Ed as saying “For me this is a great event. Wolfram is the first significant person to believe in this stuff. I’ve been very lonely&#8221;. It followed up by saying that “Mr. Fredkin, who said he was a longtime friend, said Dr. Wolfram had ‘an egregious lack of humility&#8217;”. (In some contexts, I suppose that might be a compliment.) </p>\n<p>In writing this piece I asked Steven Levy what Ed had actually said in the interview he did. His first summary in reviewing his notes was “He says he considers you a friend and then goes on endlessly about what an egomaniac you are&#8221;. But then he sent me his actual notes, and they’re somewhat revealing. Ed doesn’t claim he introduced me to cellular automata, perhaps because he realizes that Levy knows from the 1980s that that isn’t true. But then Ed tells the story about showing me reversible cellular automata, which I’d explained to Ed wasn’t true. Ed goes on to say that “Everyone who’s in science wants credit, driven probably by wanting to become famous. [Wolfram] has a larger than normal dose&#8221;. Ed says that when he had said that cellular automata underlie physics, I’d said that was crazy. (Yup, that’s true.) But then Ed said “Now he denies this&#8221;. Huh? Ed went on: “He’s a prisoner of some kind of overactive ego. I believe he might not know. Wolfram deserves loads &#038; loads of credit, but he has this personality flaw&#8221;. And so on.</p>\n<p>A month later Ed writes to me:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>From:</span> Ed Fredkin</div>\n<div><span>To:</span> Steve Wolfram</div>\n<div><span>Sent:</span> Friday, June 14, 2002 2:48 PM</div>\n<div><span>Subject:</span> ANKOS critics</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nSteve,</p>\n<p>Sometime soon I&#8217;d like to get together and talk.</p>\n<p>I&#8217;ve read a lot of your book.</p>\n<p>Take a look at the draft of a little paper of mine (attached).

After a nod to medieval metaphysicians, <a href=\"https://www.sfgate.com/science/article/Cosmic-computer-new-philosophy-to-explain-the-3264259.php\" target=\"_blank\" rel=\"noopener\">the article (under the title &#8220;Cosmic Computer&#8221;)</a> opens with “Nowadays, with a daring that might have dazzled St. Augustine and St. Thomas Aquinas, two titans of the computer world argue that everything in the universe is a kind of computer.” After analogizing me to Britney Spears, the article goes on to say “The excitement has also brought tension to the long-standing friendship between Wolfram and Fredkin, who are now wrestling with one of the bigger bummers of any scientist’s life: a dispute over originality.” The article reports: “Last week, the two men had a long, heartfelt phone conversation with each other, in which they tried to resolve their strong disagreement over priority. The conversation was amicable, but they failed to reach agreement.”</p>\n<p>And so things remained until March 2003 when Ed sent the following:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Re: NKS 2003 Conference &amp; Minicourse</div>\n<div><span>Date:</span> Thu, 20 Mar 2003 17:24:59 -0500</div>\n<div><span>From:</span> Edward Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nDear Stephen,</p>\n<p>I guess I&#8217;m on a Wolfram mailing list for potential attendees for your<br />\nBoston conference. I hope you don&#8217;t mind a little plain speaking. I<br />\nconsider that I am a friend of yours and therefor I take the risk of<br />\ntelling the emperor about his new clothes. Of course, few others<br />\nwould do so as a friend. Please don&#8217;t be offended as the plain talking<br />\nthat follows is my attempt at trying to be constructive.</p>\n<p>Your work is acquiring a reputation amongst the scientific community<br />\nthat is much less than it deserves. I find myself often in the<br />\nposition of defending you, your work and your accomplishments against<br />\nthe negative views that many hold, even though they have little<br />\nunderstanding of the significance of what you have done. They are<br />\nturned off by your egregious behavior; it distracts much of the<br />\nscientific community rendering it barely possible for them to take you<br />\nseriously . You have invented and discovered quite a few things, but<br />\nso have others. You told me you would try to give credit in ANKOS<br />\nwhere credit was due; I believed you and I believe that you tried your<br />\nbest but nevertheless you failed miserably. I guess you simply didn&#8217;t<br />\nknow how. Consider this conference: Must this conference be a one man<br />\nshow or might it actually be better for the ideas in ANKOS and better<br />\nfor SW and his overall scientific reputation if it were a real<br />\nconference where others might address the same questions? Please don&#8217;t<br />\nkid yourself into thinking that no one else has anything original,<br />\nnovel, important or interesting to say.</p>\n<p>Of course, this so-called &#8220;&#8230;first ever conference&#8221; devoted to the &#8220;&#8230;<br />\nideas and implications&#8230;&#8221; of concepts found in ANKOS might be nothing<br />\nmore than a marketing tool for Mathematica and for sales of the ANKOS<br />\nbook. If so, you ought to call a spade &#8220;spade&#8221;.</p>\n<p>You&#8217;ve done enough things (and hopefully will continue to do so) to<br />\nensure your reputation as a pioneer in various areas. This flood of<br />\nself puffery simply detracts, in the minds of many whose opinions you<br />\nought to value, from the positive reputation you deserve.</p>\n<p>I&#8217;m not one of those whose opinion of your work is in any way affected<br />\nby your unfortunate behavior. I see and understand exactly what you&#8217;ve<br />\ndone and I know and understand what your work is based on. I am human,<br />\nso I find it interesting when you now and then claim to have discovered<br />\nan idea or fact that I personally explained to you when it was<br />\nperfectly clear at the time that to you, the idea was absolutely novel.<br />\nMy model of you is that your overpowering motivation results in your<br />\nmind playing tricks on you. I really believe that you actually forget;<br />\nthat you actually re-remember the past differently than it happened.</p>\n<p>But I am the eternal optimist. I believe that even Stephen Wolfram<br />\nmight someday come around and join the collegial scientific community<br />\nwhere you receive credit and give credit; both nearly effortlessly.<br />\nThe world actually might voluntarily heap honors on you as opposed to<br />\nSW having to orchestrate &#8220;conferences&#8221; for the glorification of SW and<br />\nall the ideas claimed by SW. No one knows better than me how slow and<br />\ntorturous this process can be for new and novel big concepts, but<br />\npatience and modestly [<em>sic</em>] still seems like the better path.</p>\n<p>Please try to not be offended. I actually mean well. If you ever have<br />\nan actual, real conference, invite me to be a speaker; I&#8217;ll come. If I<br />\norganize another conference you can rest assured that you will be<br />\ninvited again (as you were for the NSF Workshop) and I hope you will<br />\ncome to talk about your ideas and maybe &#8212; maybe even stay to hear what<br />\nothers have to say on the subject. It&#8217;s not too healthy to the<br />\nscientific mind to be the only real speaker at conferences you organize<br />\nand hype for yourself.</p>\n<p>Among the very few who really are able to appreciate what you&#8217;ve done,<br />\nI am one of your greatest supporters. But I am not your average person<br />\nwith more or less normal reactions. When you reach for extra glory<br />\nand credit by stealing one of my ideas, my reaction is: &#8220;I admire your<br />\ngood taste&#8221;.</p>\n<p>Best regards</p>\n<p>Ed F</p>\n<p><span class=\"emailgray\">On Thursday, March 20, 2003, at 02:19 PM, Stephen Wolfram wrote:</span><br />\n<span class=\"emailitalic emailgray\"><br />\n&gt; In June of this year we&#8217;re going to be holding the first-ever<br />\n&gt; conference devoted to the ideas and implications of A NEW KIND OF<br />\n&gt; SCIENCE.

We talked<br />\nabout many kinds of things. It was fun. Occasionally we talked about<br />\nscience. In the early 1980s I learned a few things about cellular automata<br />\nfrom you. None were extremely influential to me, but they were fine things<br />\nthat you should be proud of having figured out—and in fact I took some<br />\ntrouble to mention them in the notes to NKS.</p>\n<p>You also told me some of your thinking about fundamental physics. I was (I<br />\nhope) polite, and tried to be helpful. But I always found what you were<br />\nsaying quite vague and slippery—and when it became definite it usually<br />\nseemed very naive. I think it&#8217;s a great pity that you&#8217;ve never taken the<br />\ntime to learn the technical details of physics as it&#8217;s currently practiced.<br />\nThere&#8217;s a lot known. And if you understood it, I think you&#8217;d be able to<br />\ntell quite quickly which of your ideas are totally naive, and which might<br />\nactually be interesting.</p>\n<p>I think it&#8217;s also a pity that—so far as I can tell—you&#8217;ve never really<br />\ntaken the time to understand what I&#8217;ve done. It&#8217;s in the end pretty<br />\nnontrivial stuff. It&#8217;s not just saying something like &#8220;the universe is a<br />\ncellular automaton&#8221; or &#8220;I have a philosophy that the universe is like a<br />\ncomputer&#8221;. It&#8217;s a big and rich intellectual structure, built on a lot of<br />\nsolid results and detailed, careful, analysis. That among other things<br />\nhappens to give a bunch of ideas about how physics might actually<br />\nwork—that have (so far as I know) almost nothing to do with things you&#8217;ve<br />\nbeen talking about.</p>\n<p>I do agree with your belief that the universe is ultimately discrete. But<br />\nof course many people have for a long time said that they thought the<br />\nuniverse might at some level be discrete. Some of those people (like<br />\nWheeler, Penrose, Finkelstein, etc.) are sophisticated physicists, and what<br />\nthey&#8217;ve said has lots of real content—it&#8217;s not just vague essay-type<br />\nstuff. Now, I don&#8217;t happen to think what they&#8217;ve specifically proposed is<br />\ncorrect. But you would be completely wrong to think (as you seem to) that<br />\nsomehow the idea that the universe might be discrete originated with you.</p>\n<p>I really encourage you to read NKS in detail, including the notes at the<br />\nback. I think there&#8217;s a lot more there than you imagine. And I think if<br />\nyou really understood it, you would be completely embarrassed to write a<br />\nnote like the one below.</p>\n<p>You&#8217;ve never struck me as being someone who is terribly interested in other<br />\npeoples&#8217; ideas. And that&#8217;s of course fine. But you shouldn&#8217;t assume you<br />\nknow their ideas just on the basis of a few buzzphrases or some such. In<br />\nsome areas of business, that approach often works. Because, as we both<br />\nknow, the ideas typically aren&#8217;t that deep. But it won&#8217;t work with a<br />\ncharacter like me doing science. There&#8217;s too much nontrivial content. You<br />\nhave to actually dig in to understand it. And from the things you say you<br />\nobviously haven&#8217;t.</p>\n<p>For twenty years I thought we had a fine personal relationship. I thought<br />\nit was a little odd that you seemed to go around telling people that you had<br />\nintroduced me to cellular automata. We talked about this a few times, and<br />\nyou admitted this wasn&#8217;t a true story. But while I thought it was a little<br />\nunreasonable for you to keep on saying something you knew wasn&#8217;t true, I<br />\ndidn&#8217;t pay much attention. It never really got in the way of our<br />\nrelationship.</p>\n<p>And then there was the incident of your NSF-funded conference. You invited<br />\nme. I said I couldn&#8217;t come. And suggested two alternates. You said fine.<br />\nBut then you never contacted these people. Which was rather embarrassing<br />\nfor me. And then, when David Reiss contacted you, you told him the<br />\nconference &#8220;was full&#8221;.</p>\n<p>Later, when we talked about it, you admitted that that was a lie—and then<br />\nblamed the lie on Raj Reddy.</p>\n<p>Frankly, I was flabbergasted by all this. That&#8217;s not the kind of<br />\ninteraction someone like me expects to have with a seasoned high-level<br />\noperative like yourself. Yes, that&#8217;s the kind of thing some sleazy young<br />\nbusinessperson might do. But not a mature businessperson who has run<br />\ncompanies and things.</p>\n<p>I still have no idea what you were thinking of. But it thoroughly shook my<br />\nconfidence in you as someone I could interact straightforwardly with.</p>\n<p>And then, of course, there&#8217;s the question of what you&#8217;ve said to journalists<br />\netc. about NKS. In detail, I don&#8217;t have much idea. But something fishy<br />\nwas surely going on. I haven&#8217;t gone and studied all the quotes from you.<br />\nBut certainly my impression was that you were trying to claim that really<br />\nlots of key things in NKS were things you had done or said first.</p>\n<p>You know that I tried to research the history carefully. And unless I<br />\nmissed something quite huge, your contributions to NKS were extremely minor,<br />\nand are certainly accurately represented in the history notes. Now of<br />\ncourse if you don&#8217;t actually understand what I&#8217;ve done in NKS, that may be<br />\nhard to see. But I can&#8217;t really help you with that.</p>\n<p>OK, where do we go from here?</p>\n<p>We talked at some length when that reporter from a San Francisco paper was<br />\ntrying to write a story about you and NKS. I thought we had a decent<br />\nconversation. But then, so far as I could tell, you went right ahead and<br />\ntold the reporter—again—exactly a bunch of things we&#8217;d agreed in our<br />\nconversation weren&#8217;t true.</p>\n<p>It was the same pattern as with telling people that you&#8217;d introduced me to<br />\ncellular automata. And it resonated in a bad way with the lie you told<br />\nabout your conference.</p>\n<p>I would have expected vastly better from you. I must say that I was<br />\npersonally most disappointed. And I concluded with much regret that I must<br />\nhave seriously misjudged you all these years.</p>\n<p>I would like nothing more than to be able to mend our relationship, and go<br />\nback to the kind of pleasant social interactions we have always had.</p>\n<p>How can that be achieved? Perhaps it&#8217;s impossible. But one step is that<br />\nyou might actually try to understand what I&#8217;ve done in NKS. That would<br />\nsurely help.</p>\n<p>&#8212; Stephen\n</p></div>\n</div>\n<p></body></html></p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Delayed reply</div>\n<div><span>Date:</span> Thu, 3 Apr 2003 23:34:17 -0500</div>\n<div><span>From:</span> Edward Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nStephen,</p>\n<p>I have been traveling and more recently have had my time gobbled up by<br />\na most urgent matter.</p>\n<p>I appreciate your quick reply to my email and I will get back to you<br />\nsometime soon. Rather than trying to respond to everything you brought up,<br />\nI will be limited to dealing with a couple of issues at a time.</p>\n<p>What I can tell you is that I am not angry, and was not angry or upset.<br />\nI have always been a non-emotional observer with regard to whatever it is<br />\nthat comes my way. That&#8217;s just my nature. It has come in handy at times,<br />\nsuch as when someone&#8217;s stupid mistake caused the single engine jet fighter<br />\nI was flying have an engine fire on take off. This required shutting down the<br />\nengine and taking other drastic actions very quickly; no time to get mad.</p>\n<p>The gist of my comments to you was not related to the work you<br />\ndocumented in NKS, but rather to the style and methodology you are using<br />\nwhile trying to get people to understand and appreciate what it is you<br />\nhave done. I certainly agree with the fact that it is extraordinarily<br />\ndifficult to get the scientific establishment to pay attention, listen,<br />\nunderstand and appreciate what you&#8217;ve done. Nevertheless, I think there<br />\nmight be a better approach to that problem than the one you are following.</p>\n<p>So, as soon as I can get a little breathing room, I&#8217;ll respond to some<br />\nof your comments. I do value our friendship and whatever I do in this regard<br />\nwill be an attempt at honest and unemotional communication with the goal of<br />\nsome better mutual understanding.</p>\n<p>By the way, I have taken the time to read and understand what you&#8217;ve<br />\ndone in NKS. I&#8217;m pretty sure that I am better able than most to appreciate<br />\nthe effort, persistence and creativity that went into that work.</p>\n<p>You have made some comments about me and my own work, and I wonder what<br />\nyou actually know about it beyond our conversations and the things you<br />\nreferenced in NKS.</p>\n<p>As soon as I can get some time I&#8217;ll continue with some further thoughts.</p>\n<p>Best regards,</p>\n<p>Ed</p>\n</div>\n</div>\n<p></body></html></p>\n<p>Ed didn’t send the promised followup. But a couple of months later <em>New Scientist</em> sent our media email address a note titled: “cover feature on Fredkin, Wolfram right to reply”, which asked for “comment on the suggestion that you first became familiar with cellular automata first at Fredkin’s lab in the 1970s and that examples in <em>A New Kind of Science</em> came out of work done in the lab”. I told Ed he should correct that—and he responded to me:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Re: cover feature on Fredkin, Wolfram right to reply.</div>\n<div><span>Date:</span> Thu, 29 May 2003 13:55:02 -0400</div>\n<div><span>From:</span> Ed Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nStephen,</p>\n<p>I carefully and clearly told the author of the NS article that to my<br />\nknowledge it is not true &#8220;&#8230; that Wolfram first became familiar with<br />\ncellular automata at Fredkin&#8217;s lab in the &#8217;70&#8217;s&#8230;&#8221; and further that<br />\nyou already knew about CA&#8217;s.</p>\n<p>My guess is that magazines see value in controversy and they would like<br />\nto attribute statements to each of us that helps them titillate their<br />\nreaders. I tried in every way I could to correct any wrong impressions<br />\nthe author had. But what they end up doing is beyond my control.</p>\n<p>As to cracking the fundamental theory of physics, I did read and did<br />\nunderstand what you wrote about in NKS, however my interests lie in<br />\nmodels that are regular and based on a simple underlying Cartesian<br />\nlattice. The models I have been working on for the past few years are<br />\ncalled &#8220;Salt&#8221; as they are CA&#8217;s similar to an NaCl crystal. You can<br />\nread about it at www.digitalphilosophy.org.</p>\n<p>My approach to being consistent with QM, SR and GR is related to the<br />\nfact that CA models of physics can exactly conserve such quantities as<br />\nmomentum, energy, charge etc. By means of a variant of Noether&#8217;s<br />\nTheorem, the physics of such CA&#8217;s can exhibited the all the symmetries<br />\nwe currently attribute to physics, but doing so asymptotically at<br />\nscales above the lattice.</p>\n<p>Thus, in my concept of a theory of physics, translation symmetry,<br />\nrotation symmetry etc. would all be violated as we currently understand<br />\nis true for time symmetry, parity symmetry and charge symmetry .</p>\n<p>No one suggests that you should agree with all my ideas, however your<br />\ncomment in your prior email to me is unnecessarily condescending:</p>\n<p><span class=\"emailitalic emailgray\">&gt; &#8220;I think it&#8217;s a great pity that you&#8217;ve never taken<br />\n&gt; the time to learn the technical details of physics as it&#8217;s<br />\n&gt; currently practiced. There&#8217;s a lot known. And if you understood<br />\n&gt; it, I think you&#8217;d be able to tell quite quickly which of<br />\n&gt; your ideas are totally naive, and which might actually be interesting.&#8221;</span></p>\n<p>What is certain is that there&#8217;s no &#8220;great pity&#8221; necessary. I actually<br />\ndo know a lot about the technical details of physics. In any case,<br />\nthirty years ago Feynman thought that I needed to learn more about<br />\ncertain aspects of QM. He was specific in what he felt was everything<br />\nmore that I needed to know (in order to make progress with my CA<br />\nideas). He offered to work with me, which was accomplished during the<br />\ncourse of the year I spent at Caltech (1974-1975). I studied, learned<br />\nmore about QM and passed the final exam that Feynman gave me. While<br />\nwe argued a lot, Feynman never accused me of having naive ideas.</p>\n<p>As to NKS 2003, it doesn&#8217;t make a lot of sense for me to come to be a<br />\nmember of the audience. If you would like me to participate in some<br />\nmeaningful way, let me know.</p>\n<p>Best regards,</p>\n<p>Ed F</p></div>\n</div>\n<p></body></html></p>\n<p>And after that exchange, Ed and I basically went back to being as we had been before—having pleasant interactions, without any particular scientific engagement. And in a sense for many years I kept out of Ed’s scientific way—not seriously working on physics again until 2019. </p>\n<p>Since 2002 I’d been living in the Boston area, so Ed and I ran into each other more often. And although Ed’s behavior over <em>A New Kind of Science</em> had disappointed and upset me, it gave me a better understanding of Ed as a human being, and a vulnerable one at that.</p>\n<h2 id=\"the-later-ed\">The Later Ed</h2>\n<p>It was always a little hard to tell just what was going on with Ed.

It prompted me (who hardly ever writes<br />\nanything) to type up my thoughts for whatever they&#8217;re worth.</p>\n<p>&#8230;</p>\n<p>You might be surprised at the number of wise and intelligent people who<br />\nreally appreciate Pat and his works. Yet after more than 30 years of<br />\nfitful, diverse yet nearly continuous support, Pat has come to a<br />\nsituation that, to him, looks like the end of the line.</p>\n<p>&#8230;</p>\n<p>I, unfortunately, am no longer in a position to personally provide the<br />\nkind of modest support that Pat needs to continue his church-mouse kind<br />\nof existence.</p>\n<p>&#8230;</p>\n<p>There is no doubt that Pat can be a difficult person to help, but I<br />\nnotice that he has mellowed with age. Of course, Wolfram Research is<br />\nnot a charitable institution. But I believe that Pat&#8217;s ideas on<br />\nideonomy are really important and that those ideas may form the basis<br />\nof interesting future applications. The point of all this is that if<br />\nwhat Pat is doing seems interesting to you, some arrangement with<br />\nWolfram Research might make sense.</p>\n</div>\n</div>\n<p></body></html></p>\n<p>(True to form, Gunkel followed up with a very forthright note, including a scathing critique he’d written of <em>A New Kind of Science—</em>as well as of Ed’s theories. That wouldn’t have deterred me, but I couldn’t see anything Gunkel could actually do for us, so I never pursued this.)</p>\n<p>But did Ed’s note imply that Ed was running out of money? I’d always assumed some kind of vast business empire lurking in the background, but now I wasn’t sure. </p>\n<p>I saw Ed only a few times in the next couple of years—at events like a Festschrift for Sulak and a bat mitzvah for one of Feynman’s granddaughters. But as usual, he was eager to tell stories, some of which I hadn’t heard before—mostly about things far in the past. He said that in the early 1960s John Cocke had stolen the idea of RISC architecture from his murdered friend Ben Gurley, though it had taken him two decades to get it taken seriously. He said that around the same time he’d been pulled in by the Air Force to help with analysis of blast waves from nuclear tests (and that story came with descriptions of B-52s doing loop-the-loop maneuvers when they dropped atomic bombs). He said that he’d once demoed the Muse music system (which, he emphasized, he, not Minsky, had invented) to an astonished audience in the Soviet Union. He said that he’d advised Richard Branson on his transatlantic balloon trip, telling him his butane burners weren’t correctly mounted—and in fact they fell off. And so on.</p>\n<p>In 2005 Ed told me he’d been working with a programmer in California named Dan Miller (who’d developed audio compression software [and been at the NKS 2003 conference that Ed had been so upset about]) on the new 3D cellular automaton he’d invented that he called the “SALT architecture” because its pattern of updates were like the Na and Cl in a salt crystal.</p>\n<p>But then in 2008 Ed told me he’d sold his island—presumably relieving whatever financial issues he’d had before—and suddenly Ed started to show up much more. He told me (as he did quite a few times) that he was working on a book (which never materialized). He told me he was teaching a course at Carnegie Mellon on the “Physics of Theoretical Computation”—which was apparently actually a very-much-as-before “engineering-style” effort to explore building features of physics from a cellular automaton, now with his SALT architecture. He invited me to a dinner at his house in honor of ‘t Hooft, photographed here with Ed, me and Sulak:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img1-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img1-min.png' alt='Click to enlarge' title='Click to enlarge' width='515' height='355'/></a></p>\n<p>That fall, Ed came to the Midwest NKS Conference in Indiana, here photographed in a discussion with Greg Chaitin, me and others:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img2.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img2.png' alt='Click to enlarge' title='Click to enlarge' width='609' height='213'/></a></p>\n<p>I would interact with Ed quite regularly after that—most often with him telling me about his use of Mathematica and soon <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>. In 2012 Ed—now aged 78—sent me a nice “I have an idea” email (I made the requested introduction, though I’m not sure if this ever went anywhere):</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Alpha and Problem Solving</div>\n<div><span>Date:</span> Fri, 19 Oct 2012 20:12:01 +0000</div>\n<div><span>From:</span> Edward Fredkin</div>\n<div><span>To:</span> Steve Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nSteve,</p>\n<p>The first thing I taught at MIT was a course in general problem solving (in 1968).<br />\nI&#8217;m now developing a new course on General Problem Solving which I expect to<br />\noffer first at Harvard&#8217;s HILR program. Part of the motivation came from watching<br />\nJoyce struggle with a Harvard course on Chemistry, where a lot of the homework<br />\ninvolved units conversions. I noticed that Alpha promptly solved many of Joyce&#8217;s<br />\nhomework problems including some involving chemical reactions. (The course<br />\nwas really for students planning to take the MCAT Exam in order to get into Medical<br />\nSchool). One clue that you might give to the Alpha developers, is to work toward<br />\ngetting Alpha to have more of the capabilities necessary to pass different standard<br />\ntests that involve various kinds of quantitative analysis. (Of course, you might<br />\nhave already done so.)</p>\n<p>You might recall that I discussed the issue of units conversion with you long ago<br />\n(before Mathematica), and you described the idea you then had that turned into<br />\nConvert in Mathematica.</p>\n<p>In any case, Alpha is fantastic, and getting better all the time. My plan is that every<br />\none of my students must use Alpha for every problem that involves numbers, along<br />\nwith some that don&#8217;t involve numbers. My motto is John McCarthy&#8217;s dictum:<br />\n&#8220;Those who refuse to do arithmetic are doomed to talk nonsense!&#8221; However, with<br />\nAlpha, the problem solver doesn&#8217;t have to do the arithmetic or the units<br />\nconversions; Alpha can do it!</p>\n<p>It would be helpful if I could get a little bit of cooperation from someone in the Alpha<br />\ngroup. Basically, I will want to talk to an Alpha expert from time to time to make sure<br />\nI&#8217;m taking advantage of the best that Alpha can do along with resources already<br />\ndeveloped for introducing Alpha to new users. My initial students will be drawn from<br />\na group of retirees who, while clearly above average in intelligence, may have few<br />\nrecently used skills in mathematics. I also expect that almost all of my initial<br />\nstudents will be first time Alpha users. Again, I might profit from discussion<br />\nwith someone who has thought about how to introduce Alpha to beginners.</p>\n<p>Let me know what you think or, if you like, we could get together to talk about it.</p>\n<p>Best regards and Congratulations!</p>\n<p>Ed\n</p></div>\n</div>\n<p></body></html></p>\n<p>In 2014, when I recorded some oral history with Ed—now age 80—he was again brimming with ideas. The one he was most excited about had to do with weather prediction. It started from the observation that most smartphones have pressure sensors in them. Ed’s idea was to use these—and more—to create a sensor net that would continuously collect billions of pressure measurements, to be fed as input to weather forecast codes. Channeling his lifelong interest in reversible computing he imagined that the codes could be made reversible, and that running backwards from an incorrect prediction could tell one where more data had to be collected. Then Ed imagined doing this by having tiny balloons all over the place—with nothing that would cause trouble if a plane ran into it. He had a whole plan for partners he wanted to get (and, yes, he wanted us to be part of it too). And in typical Ed fashion, it was all laced with stories:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">You know, I had this personal experience with weather. I was flying a glider along at 16,000 feet, and I encountered sink. You know, sink is wind blowing down. And the speed of the sink was 10,000 feet a minute. I was at 16,000 feet. And two minutes later, I was on the ground landing. Not on purpose. You know my attitude was—if I don’t see a big grading on the ground—[the wind] can’t keep going this way all the way down, so I won’t be killed. Actually, in that same storm, one of the pilots was killed.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">&#8230;</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">The weather people just aren’t into the vertical movement of air. They do everything in layers. But this went through a lot of layers all at once in an organized fashion. So the point is that to talk about thousands or even millions of sensors makes no sense. You’re not going to do good weather until you get billions of sensors. That’s my opinion.</p>\n</blockquote>\n<p>We talked about whether sensitive dependence on initial conditions destroys all predictability in fluid dynamics. I have theoretical and computational reasons to think it doesn’t. But Ed had a story:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">There’s a mountain in California I happen to know, and I have a picture of a cloud street that starts on that mountain because it has a very peculiar geometry, and then runs for 2,000 miles.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">So this particular mountain has an area of its rock that faces towards the east and it’s big. And what happens is when the Sun is shining on that and the wet wind is coming from the Pacific and so on, you get this big cumulus cloud that flows back this way, and then you get another one and it pulses. You get one after another. And these are very stable things and they travel a very long way. So my point is that amidst all the randomness there’s a lot of order that can be found and understood. There are regions that have funny properties. They’re much more temperature stable. There’s like islands of stability. And things like that get ignored by everything people are doing today, you know what I mean?</p>\n</blockquote>\n<p>I would send things I’d written to Ed. I didn’t really think he’d read them. But I thought he might at least enjoy their concepts. And often he would respond with ideas of his own. I sent him an announcement about our <a href=\"https://www.wolfram.com/language/tweet-a-program/\">Tweet-a-Program</a> project (now reconfigured because of Twitter changes) with the one-line comment (reflecting his “best programmer” self-characterization): “A new frontier of programming prowess?” He responded, in typical Ed fashion, with an idea—that’s actually a little reminiscent of modern AI image generation:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Subject:</span> Re: Tweet-a-Program</div>\n<div><span>Date:</span> Fri, 19 Sep 2014 21:25:47 +0000</div>\n<div><span>From:</span> Edward Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nHi,</p>\n<p>I like it!

He also sent me a <a href=\"https://arxiv.org/pdf/1206.2060v1.pdf\" target=\"_blank\" rel=\"noopener\">paper he&#8217;d written</a> about his SALT cellular automaton:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img3.png' alt='Click to enlarge' title='Click to enlarge' width='568' height='404'/></a></p>\n<p>Finally—and without my help—Ed seemed to have mastered the art of academic papers. This one was on the arXiv preprint server. Others—with titles like “<a href=\"http://52.7.130.124/wp-content/uploads/2015/07/intro-to-DP.pdf\" target=\"_blank\" rel=\"noopener\">An Introduction to Digital Philosophy</a>”—had appeared in academic journals. (Ones with titles like “<a href=\"http://www.ai.mit.edu/projects/im/ftp/poc/fredkin/New-Cosmogony\" target=\"_blank\" rel=\"noopener\">A New Cosmogony</a>” and “<a href=\"http://www.ai.mit.edu/projects/im/ftp/poc/fredkin/Finite-Nature\" target=\"_blank\" rel=\"noopener\">Finite Nature</a> ” were more privately circulated.) But what most struck me about this particular paper was that—for the first time—it seemed to have actual images of cellular automaton behavior. Ever since those few minutes with the PERQ computer on Ed’s island in 1982 I hadn’t seen Ed ever show anything like that. And now Ed was again chasing that old question Minsky had asked, of making a circle with a cellular automaton. </p>\n<p>At the time, I didn’t have a chance to see what Ed had actually done, and whether he’d finally solved it. But in writing this piece, I decided I’d better try to find out. The actual rule—that Ed and Dan Miller called “<a href=\"https://arxiv.org/ftp/nlin/papers/0501/0501022.pdf\" target=\"_blank\" rel=\"noopener\">BusyBoxes</a>”—is quite complicated, involving knight’s-move neighborhoods, etc. Their claim was that starting with a string of cells in a particular configuration, the average of their positions would trace out what in the limit of a long string would be a circle:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img4_copy.txt' data-c2c-type='text/html'> <video loading='lazy' height=\"auto\" width=\"256\" style=\"margin-left:0px\" muted=\"\" alt=\"\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/08/Circular-Motion-of-Strings-CA-v2.mov\" autoplay=\"\" loop=\"\" playsinline><br />\n</video></div>\n</p></div>\n<p>At first it looks like a kind of magic trick (and no, nothing is bouncing off any “walls”; the direction changes are just a consequence of the initial pattern of cells). But if you keep all the locations that get visited, things start to seem less mysterious—because what you realize is that the “basket” that gets “woven” is actually just a cube, viewed from a corner:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img5.png' alt='' title='' width='240' height='255'> </div>\n</p></div>\n<p>Where does the apparent circle come from? The details are a bit complicated—and I’ve put them in an appendix below. But suffice it say to that Ed’s old nemesis—calculus—comes in very handy. And in fact it lets one show that although one gets almost a circle, it’s not quite a circle; even with an infinite string, its radius is still wiggling by about 0.5% as one goes around the “circle”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082223Later6-img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082223Later6-img1.png' alt='' title='' width='358' height='99'> </div>\n</p></div>\n<p>And—as we’ll see below—remarkably enough one can get a closed-form result for the amount of wiggliness (here computed as the ratio of maximum to minimum radius): </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img7.png' alt='' title='' width='355' height='42'> </div>\n</p></div>\n<p>In earlier years, Ed might have tried to say that generating a circle (which this doesn’t) was tantamount to showing that a cellular automaton could reproduce physics. But by now I think he realized that it was really much more complicated than that. And he wasn’t mentioning physics much to me anymore. But—perhaps not least because many of his longtime interlocutors had by then died—he was interacting with me more than before. And perhaps he was even beginning to think that I might have a bit more to contribute than he’d assumed.</p>\n<p>In December 2015 I sent Ed a <a href=\"https://writings.stephenwolfram.com/2015/12/untangling-the-tale-of-ada-lovelace/\">piece I’d written</a> to celebrate the bicentenary of Ada Lovelace, and he responded:</p>\n<p><body></p>\n<div class=\"email\">\n<div class=\"emailhead\">\n<div><span>Date:</span> Fri, 11 Dec 2015 15:58:14 +0000</div>\n<div><span>From:</span> Edward Fredkin</div>\n<div><span>To:</span> Stephen Wolfram</div>\n</div>\n<p></p>\n<div class=\"emailbody\">\nStephen,</p>\n<p>I was truly blown away by your essay re Ada Lovelace! You&#8217;ve got a lot<br />\nmore to give the world than I had imagined, and I, more than anyone else,<br />\nappreciate what you might still be capable of accomplishing.</p>\n<p>It&#8217;s too bad that some persons at MIT, for far too long, hung onto one<br />\ndimensional views focussed on what Macsyma might have been. My own<br />\nimpressions have always been different, I recognized your potential long<br />\nago and consequently invited you to one of my Mosqito Island conferences<br />\nsome 3.5 decades ago.</p>\n<p>In any case, much of what Mathematica makes possible is very important and<br />\nvaluable to me. As you know I was an early user and continue to be a<br />\nuser.</p>\n<p>Many of my interests have run along many paths opened up by activities you<br />\nhave instigated at Wolfram. Wolfram Alpha and its connections to Siri,<br />\nare examples.</p>\n<p>Your new book &#8220;An Elementary Introduction to the Wolfram Language&#8221; (I<br />\ndon&#8217;t yet have a hard copy) fits in with a project I had in mind for my<br />\ngrandchild Robert, who at age 6 already seems to be extraordinarily<br />\ntalented mathematically.</p>\n<p>To cut to the chase, I want to make a proposal: Although I&#8217;m too old to<br />\nbe a regular employee, I&#8217;d nevertheless like to have an association with<br />\nWolfram, where I might be able to contribute ideas, and solve problems<br />\n(I&#8217;m still quite good at that).</p>\n<p>I won&#8217;t need much from you other than your opening the door to my<br />\ninvolvement at Wolfram. What I have in mind would be an arrangement<br />\nwhere I could work for Wolfram, with some kind of arrangement other than<br />\nfull time employment.</p>\n<p>I&#8217;ve attached something I wrote recently.</p>\n<p>Ed\n</p></div>\n</div>\n<p></body></html></p>\n<p>Gosh! That was an unexpected development. Flattering, I suppose. But my main reaction was a kind of sadness. Yes, after all these years, Ed had finally read something I’d written. But somehow his response sounded like he was surrendering. This wasn’t the “I-want-to-do-everything-for-myself” Ed I had known all this time. This was an Ed who somehow felt he needed us to support him. And while our company has been able to absorb a great many “unusual” people—with terrific success—Ed seemed like he was pretty far outside our envelope. </p>\n<p>At the time, I didn’t look at the attachment Ed sent with his email. But opening it now adds to my sense of sadness. It was a 13-page document about a system Ed imagined that would help people with “various forms of cognitive disabilities”, including a section on “Dementia and Alzheimer’s”: </p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img8.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img8.png' alt='Click to enlarge' title='Click to enlarge' width='622' height='584'/></a></p>\n<p>It wasn’t until 2017 that Ed explicitly mentioned to me that his short-term memory was failing—though in talking to him it had been increasingly obvious for several years. He said he’d joined a group of people who were writing their memoirs. I told him I’d look forward to seeing his, though I’m not sure he ever made much progress on them.</p>\n<p>Ed continued to send me ideas and proposals. There was a very Ed-like “global idea” about creating a system “GM” (presumably for “General Mathematician”) that would effectively “learn all of mathematics” by automatically reading math books, etc. (yes, definite overtones of what’s happening with LLM-meets-Wolfram-Language):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img9.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img9.png' alt='Click to enlarge' title='Click to enlarge' width='620' height='483'/></a></p>\n<p>Later there were several pieces of mail about a new idea for factoring integers. In the first of them (from 2016), Ed told me that when the NeXT computer first came out (in 1989) he’d used Mathematica on it to simulate a reversible hardware multiplier. And being reminded of this by a historical piece I’d written, he said it had “started me thinking, again, about that problem and I had a new insight that appears to so greatly reduce the complexity of a reversible multiplier so as to possibly make it better at factoring large integers than current algorithms.” He wrote me about this several more times, suggesting various kinds of collaborations. Finally, in 2018 he told me how the method worked, saying it involved doing reversible arithmetic using balanced ternary. (Strangely enough, years earlier Ed had told me about Soviet computers that also used balanced ternary.)</p>\n<p>I think that was the last technical conversation I had with Ed. A couple of years later I sent him the book about our Physics Project with the inscription:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img10-v3.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img10-v3.png' alt='Click to enlarge' title='Click to enlarge' width='388' height=''/></a></p>\n<p>And I would see him at least once a year at the Boston-area physics get-together organized by Boston University. He would always tell me stories. Often the same stories, and sometimes stories about me. And indeed as I was writing this piece I actually found a <a href=\"https://www.youtube.com/watch?v=ROv1HX-gdas\" target=\"_blank\" rel=\"noopener\">video Ed made in November 2020</a> that has such a story, albeit by this point seriously muddled (and, no, I’ve basically never “run” a cellular automaton by hand in my life!): </p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I used to organize meetings in the Caribbean and I did this because I had an island in the Caribbean &#8230; I invited Wolfram to come down. Wolfram had done pioneering work in cellular automata. &#8230; He was a great guy, you know, and I wanted him to get on the bandwagon &#8230; He shows up at the meeting and he had done all his work by hand as had everyone else in cellular automata. He didn’t think of using a computer. [!] I had a display processor that I modified to be able to run a cellular automaton with the stuff that it used to put text up on the screen. And so I’m showing him a cellular automata running at 60 frames a second continuously like a movie. This was 10,000 times faster than doing it by hand which is what he’d always done. He never thought of using a computer to do cellular automata and he turns around and walks out and and he left the island and went back to someplace else. So [later] I went to his meeting at Los Alamos and I ran into him again and he was now doing computer work. And I said to him “How come in all your work you don’t have a reversible [rule]”, and he says to me “Oh, reversible ones are all trivial”. And I went up and this is the most telling thing about his intellect: he’s a very smart guy [and when I] showed him how he could change his rule slightly and make it reversible his eyes just about popped out of his head and he knew I was correct.</p>\n</blockquote>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">I may have introduced him to this field but what he has done is he is far better than I at getting other people involved. I’ve never bothered and I don’t have the talent that he has for that. What he did was he came up with similar ideas and initially he didn’t give me the credit I thought I deserved. But it became apparent to me that he did this independently and he’s better at writing things and better at hiring bright people who can do things than I ever was.</p>\n</blockquote>\n<p>And right after that, Ed ends the video with:</p>\n<blockquote>\n<p style=\"font-style: normal; line-height: 1.4; font-size: .98rem; text-indent: 0;\">As I look back on my career I’ve had a fantastic life and I’m not unhappy about any aspect of it because, you know, I’ve accomplished everything I might have done and in spite of various handicaps—like not being a writer—I still have done a lot and the world, uh, understands me, I think, and appreciates what I’ve done.</p>\n</blockquote>\n<p>When I saw Ed in 2022 he wasn’t able to say much. But, though it was a struggle, he was keen to make one point to me, that seemed to matter a lot to him: “You’ve managed to get people to follow you”, he said “I was never able to do that”. I saw Ed one last time this May. Joyce explained that Ed had “bumped his head”, and, in a very Ed-like way, she was avoiding a repeat by getting him to wear a bike helmet. She wanted someone to snap a picture of me and her with Ed:</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img11.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img11.png' alt='Click to enlarge' title='Click to enlarge' width='414' height='310'/></a></p>\n<p>Six weeks later, Ed died, at the age of 88. </p>\n<p>I went to see Joyce and Rick a few weeks later, among other things to check facts for this piece. I’d heard from Ed that his ancestors had provided wood for the imperial palace in St. Petersburg. But I’d also heard from someone else that Ed had said he was descended from Mongolian royalty. And as I was about to leave, I thought I might as well ask. “Oh yes”, they said. “And Ed’s father even wrote a historical novel about it”. And they showed me two books (both from the mid-1980s):</p>\n<p><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/08/sw082123Later-img12-min.png\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082123Later-img12-min.png' alt='Click to enlarge' title='Click to enlarge' width='506' height='358'/></a></p>\n<p>I’m not sure who Sarah, Queen of Mongolia was, but the book blurb claims that Ed’s father was her great-great-great-grandson—and goes on to speak of the “strong family inheritance of a mind that analyzes not only the injustice of human oppression but offers realistic and beneficial solutions”. </p>\n<h2 id=\"summing-up-ed\">Summing Up Ed</h2>\n<p>“Can that really be true?” I often asked myself when hearing yet another of Ed’s implausible stories. And of course it didn’t help that stories he told—even to me—about me weren’t true. But the remarkable thing in writing this piece is that I’ve been able to verify that a lot of Ed’s stories—implausible though they may have sounded—were in fact true. Yes, they were often embellished, and parts that didn’t reflect so well on Ed were omitted. But together they defined a remarkable tapestry of a life. </p>\n<p>It was in many ways a very independent life. Ed had friends and family members to whom he stayed close throughout his life. But mostly it was “Ed for himself, against the world”. He didn’t want to learn anything from anyone else; he wanted to figure out everything for himself. He wanted to invent his own ideas; he wasn’t too interested in other people’s. In a rather Air-Force-pilot kind of way (“eject or not?”) he liked to be decisive—and he liked to be incisive too, always figuring out a clear, simple thing to say. Sometimes that came across as naive. And sometimes it was in fact naive. But mostly Ed didn’t seem to mind much; he would just go on to another idea.</p>\n<p>Ed was a great storyteller, and an engaging speaker. For some reason he developed the theory that he couldn’t write—but there’s ample evidence, going back even to his teenage years, that this wasn’t true. If there was a problem, it was with content, not writing. And the issue with the content was that it tended to just be too Ed-specific—too insular—and not connected enough for other people to be able to understand or appreciate it. </p>\n<p>I don’t know what Ed was like as a manager; I rather suspect he may have suffered from trying to be a bit too clever, with too many ideas and too much gamification. In the end, he felt he’d failed as a leader, and perhaps that was inevitable given how independent he always wanted to be. Despite his stints as an academic administrator and as a CEO, Ed was in the end fundamentally a lone warrior (and problem solver), not a general.</p>\n<p>And what about all those ideas? Most never developed very far. Some were pretty wild. But many had at least a kernel of visionary insight. The details of the universe as a cellular automaton didn’t make sense. But the idea that the universe is somehow computational is surely correct. And spread over the course of more than six decades, Ed spun out nuggets of ideas that would later appear—usually much more developed—in a remarkable range of areas. </p>\n<p>Ed projected a kind of personal serenity—yet he was in many ways deeply competitive. Most of the time, though, he was able to define the arena of his competitiveness so idiosyncratically that there really weren’t other contenders. And I think in the end Ed felt pretty good about all the things he’d managed to do in his life. It was fitting that he owned an actual island. Because somehow an island was a metaphor for Ed’s life: separate, independent and unique.</p>\n<h2 id='thanks' style='font-size:1.2rem'>Thanks</h2>\n<p style='font-size:90%'>I&#8217;ve had help with information for this piece from many people, including Joyce Fredkin, Rick Fredkin, Simson Garfinkel, Andrea Gerlach, Bill Gosper, Howard Gutowitz, Steven Levy, Norm Margolus, Margaret Minsky, Dave Moon, John Moussouris, Mark Nahabedian, Walter Parkes, David Reiss, Brian Silverman, George Sulak, Larry Sulak and Matthew Szudzik.

In the continuum limit, there’s effectively a parameter <em>t</em> that defines where on each “layer curve” one is at a particular time. Conveniently enough, the length of all the layer curves is the same (for a unit cube it is 3 <span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/08/sw082223Appendix-img8.png' width= '22' height='20' align='absmiddle'></span> ≈ 4.2).

Since the edges of the layer polygons are always straight, in each of a series of “piecewise regions” in <em>s</em> and <em>t</em> (with breakpoints defined by the corners of the polygons), we get expressions for <em>x</em> and <em>y</em> that are linear in <em>s</em> and <em>t</em>: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/08/sw082223Appendix-img10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/08/sw082223Appendix-img10.png' alt='' title='' width='350' height='186'> </div>\n</p></div>\n<p>One subtlety is that the string in essence turns as time progresses, so that it effectively samples a different <em>t</em> value for different layers <em>s</em>.

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.

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&#8217;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=\" \" /> hat <img title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071123rightarrow.png\" alt=\"\" width=\"16\" height=\" \" /> 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&#8217;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=''> </div>\n</p></div>\n<p>Our “standard cat” is in the middle. But as we move away from the “standard cat” point, progressively weirder things happen. For a while there are recognizable (if perhaps demonic) cats to be seen. But soon there isn’t much “catness” in evidence—though sometimes hats do remain (in what we might characterize as an “all hat, no cat” situation, reminiscent of the Texan “all hat, no cattle”). </p>\n<p>How about if we pick other planes through the standard cat point? All sorts of images appear:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img2_copy.txt' data-c2c-type='text/html'>\n<table>\n<tr>\n<td><a class=\"magnific image\" style=\"margin-right: 5px \"alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img3.png\"><img alt=\"Click to enlarge\" title=\"Click to enlarge\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img3A.png\" width=\"305\" height=\"\" /></a></td>\n<td><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img4.png\"><img alt=\"Click to enlarge\" title=\"Click to enlarge\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img4A.png\" width=\"305\" height=\"\" /></a></td>\n</tr>\n<tr>\n<td><a class=\"magnific image\" style=\"margin-right: 5px\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img5.png\"><img style=\"margin-top: 5px\" alt=\"Click to enlarge\" title=\"Click to enlarge\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img5A.png\" width=\"305\" height=\"\" /></a></td>\n<td><a class=\"magnific image\" alt=\"\" title=\"\" href=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img6.png\"><img style=\"margin-top: 5px\" alt=\"Click to enlarge\" title=\"Click to enlarge\" src=\"https://content.wolfram.com/sites/43/2023/07/sw071623sec3-45img6B.png\" width=\"305\" height=\"\" /></a></td>\n</tr>\n</table>\n</div>\n</div>\n<p>But the fundamental story is always the same: there’s a kind of “cat island”, beyond which there are weird and only vaguely cat-related images—encircled by an “ocean” of what seem like purely abstract patterns with no obvious cat connection. And in general the picture that emerges is that in the immense space of possible “statistically reasonable” images, there are islands dotted around that correspond to “<a href=\"https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/#the-concept-of-concepts\">linguistically describable concepts</a>”—like cats in party hats. </p>\n<p>The islands normally seem to be roughly “spherical”, in the sense that they extend about the same nominal distance in every direction. But relative to the whole space, each island is absolutely tiny—something like perhaps a fraction 2<sup>–2000</sup> &#8776; 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, &#8220;foraged&#8221; 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/\">&#8220;pure motion&#8221; 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&#8217;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 (&#8220;class 2&#8221;) 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=\" \" /> and <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\" \" />, 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=\" \" /> and <img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\" \" />, 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=\" \" />”, 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=\" \" />”:</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=\" \" />” attractor or the “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\" \" />” 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=\" \" />” or “<img style=\"margin-bottom: -2px\" title=\"\" src=\"https://content.wolfram.com/sites/43/2023/07/B2helvetica.png\" alt=\"\" width=\"11\" height=\" \" />” 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=\" \" />”, 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=\" \" />” 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=\" \" />”.</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=\" \" /> <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>.

It’s only been 196 days since we released <a href=\"https://reference.wolfram.com/language/guide/SummaryOfNewFeaturesIn132\">Version 13.2</a>, but there’s a lot that’s new, not least a whole subsystem around LLMs. </p>\n<p><a href=\"https://www.youtube.com/watch?v=HxWg8exJxNY\">Last Friday (June 23) we celebrated 35 years</a> since <a href=\"https://reference.wolfram.com/legacy/v1/\">Version 1.0</a> of Mathematica (and what’s now Wolfram Language). And to me it’s incredible how far we’ve come in these 35 years—yet how consistent we’ve been in our mission and goals, and how well we’ve been able to just keep building on the foundations we created all those years ago.<span id=\"more-51812\"></span></p>\n<p>And when it comes to what’s now Wolfram Language, there’s a wonderful timelessness to it. We’ve worked very hard to make its design as clean and coherent as possible—and to make it a timeless way to elegantly represent computation and everything that can be described through it. </p>\n<p>Last Friday I fired up Version 1 on an old Mac SE/30 computer (with 2.5 megabytes of memory), and it was a thrill see functions like <tt><a href=\"http://reference.wolfram.com/language/ref/Plot.html\">Plot</a></tt> and <tt><a href=\"http://reference.wolfram.com/language/ref/NestList.html\">NestList</a></tt> work just as they would today—albeit a lot slower. And it was wonderful to be able to take (on a floppy disk) the notebook I created with Version 1 and have it immediately come to life on a modern computer. </p>\n<p>But even as we’ve maintained compatibility over all these years, the scope of our system has grown out of all recognition—with everything in Version 1 now occupying but a small sliver of the whole range of functionality of the modern Wolfram Language:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/06/updated-88-2023.png' alt='Versions 1.0 and 13.3 of Wolfram Language compared' title='Versions 1.0 and 13.3 of Wolfram Language compared' width='620' height=''/></p>\n<p>So much about Mathematica was ahead of its time in 1988, and perhaps even more about Mathematica and the Wolfram Language is ahead of its time today, 35 years later. From the whole idea of symbolic programming, to the concept of notebooks, the universal applicability of symbolic expressions, the notion of computational knowledge, and concepts like instant APIs and so much more, we’ve been energetically continuing to push the frontier over all these years.</p>\n<p>Our long-term objective has been to build a full-scale computational language that can represent everything computationally, in a way that’s effective for both computers and humans. And now—in 2023—there’s a new significance to this. Because with the advent of LLMs our language has become a unique bridge between humans, AIs and computation. </p>\n<p>The attributes that make Wolfram Language easy for humans to write, yet rich in expressive power, also make it ideal for LLMs to write. And—unlike traditional programming languages— Wolfram Language is intended not only for humans to write, but also to read and think in. So it becomes the medium through which humans can confirm or correct what LLMs do, to deliver computational language code that can be confidently assembled into a larger system.</p>\n<p>The Wolfram Language wasn’t originally designed with the recent success of LLMs in mind. But I think it’s a tribute to the strength of its design that it now fits so well with LLMs—with so much synergy. The Wolfram Language is important to LLMs—in providing a way to access computation and computational knowledge from within the LLM. But LLMs are also important to Wolfram Language—in providing a rich linguistic interface to the language. </p>\n<p>We’ve always built—and deployed—Wolfram Language so it can be accessible to as many people as possible. But the advent of LLMs—and <a href=\"https://writings.stephenwolfram.com/2023/06/introducing-chat-notebooks-integrating-llms-into-the-notebook-paradigm/\">our new Chat Notebooks</a>—opens up Wolfram Language to vastly more people. <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a> lets anyone use natural language—without prior knowledge—to get questions answered. Now with LLMs it’s possible to use natural language to start defining potential elaborate computations. </p>\n<p>As soon as you’ve formulated your thoughts in computational terms, you can immediately “explain them to an LLM”, and have it produce precise Wolfram Language code. Often when you look at that code you’ll realize you didn’t explain yourself quite right, and either the LLM or you can tighten up your code. But anyone—without any prior knowledge—can now get started producing serious Wolfram Language code. And that’s very important in seeing Wolfram Language realize its potential to drive “computational X” for the widest possible range of <nobr>fields X.</nobr></p>\n<p>But while LLMs are “the biggest single story” in Version 13.3, there’s a lot else in Version 13.3 too—delivering the latest from our long-term research and development pipeline. So, yes, in Version 13.3 there’s new functionality not only in LLMs but also in many “classic” areas—as well as in new areas having nothing to do with LLMs.</p>\n<p>Across the 35 years since Version 1 we’ve been able to continue accelerating our research and development process, year by year building on the functionality and automation we’ve created. And we’ve also continually honed our actual process of research and development—for the past 5 years sharing our design meetings on <a href=\"https://livestreams.stephenwolfram.com/\">open livestreams</a>. </p>\n<p>Version 13.3 is—from its name—an “incremental release”. But—particularly with its new LLM functionality—it continues our tradition of delivering a long list of important advances and updates, even in incremental releases.</p>\n<h2 id=\"llm-tech-comes-to-wolfram-language\">LLM Tech Comes to Wolfram Language</h2>\n<p>LLMs make possible many important new things in the Wolfram Language. And since I’ve been discussing these in <a href=\"https://writings.stephenwolfram.com/category/wolfram-language/\">a series of recent posts</a>, I’ll just give only a fairly short summary here.

And it’s a great example of using an LLM as a “linguistic interface” with common sense, that can generate precise computational language, which can then be run to get a result.</p>\n<p>This is all very new technology, so we don’t yet know what patterns of usage will work best. But I think it’s going to go like this. First, you have to think computationally about whatever you’re trying to do. Then you tell it to the LLM, and it’ll produce Wolfram Language code that represents what it thinks you want to do. You might just run that code (or the Chat Notebook will do it for you), and see if it produces what you want. Or you might read the code, and see if it’s what you want. But either way, you’ll be using computational language—Wolfram Language—as the medium to formalize and express what you’re trying to do.</p>\n<p>When you’re doing something you’re familiar with, it’ll almost always be faster and better to think directly in Wolfram Language, and just enter the computational language code you want. But if you’re exploring something new, or just getting started on something, the LLM is likely to be a really valuable way to “get you to first code”, and to start the process of crispening up what you want in computational terms.</p>\n<p>If the LLM doesn’t do exactly what you want, then you can tell it what it did wrong, and it’ll try to correct it—though sometimes you can end up doing a lot of explaining and having quite a long dialog (and, yes, it’s often vastly easier just to type Wolfram Language code yourself):</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062723sec2img2-1.png' alt='Draw red and green semicircles' title='Draw red and green semicircles' width='620' height='957'> </p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062723sec2img3-1.png' alt='Redraw red and green semicircles' title='Redraw red and green semicircles' width='620' height='1035'></p>\n<p>Sometimes the LLM will notice for itself that something went wrong, and try changing its code, and rerunning it:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062723sec2img4.png' alt='Make table of primes' title='Make table of primes' width='620' height='684'> </p>\n<p>And even if it didn’t write a piece of code itself, it’s pretty good at piping up to explain what’s going on when an error is generated: </p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062723sec2img5-1.png' alt='Error report' title='Error report' width='620' height='291'></p>\n<p>And actually it’s got a big advantage here, because “under the hood” it can look at lots of details (like stack trace, error documentation, etc.) that humans usually don’t bother with.</p>\n<p>To support all this interaction with LLMs, there’s all kinds of new structure in the Wolfram Language. In Chat Notebooks there are chat cells, and there are chatblocks (indicated by gray bars, and generating with <span class=\"kbd\"><kbd>~</kbd></span>) that delimit the range of chat cells that will be fed to the LLM when you press <span class=\"kbd\"><kbd>shift</kbd><kbd>enter</kbd></span> on a new chat cell. And, by the way, the whole mechanism of cells, cell groups, etc. that we invented 36 years ago now turns out to be extremely powerful as a foundation for Chat Notebooks.</p>\n<p>One can think of the LLM as a kind of “alternate evaluator” in the notebook. And there are various ways to set up and control it. The most immediate is in the menu associated with every chat cell and every chatblock (and also available in the notebook toolbar):</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062723sec2img6-1.png' alt='Chat cell and chatblock menu' title='Chat cell and chatblock menu' width='373' height='359'> </p>\n<p>The first items here let you define the “persona” for the LLM. Is it going to act as a Code Assistant that writes code and comments on it? Or is it just going to be a Code Writer, that writes code without being wordy about it? Then there are some “fun” personas—like <span class=\"promptformatted\">Wolfie</span> and <span class=\"promptformatted\">Birdnardo</span>—that respond “with an attitude”. The <tt>Advanced Settings</tt> let you do things like set the underlying LLM model you want to use—and also what tools (like Wolfram Language code evaluation) you want to connect to it.</p>\n<p>Ultimately personas are mostly just special prompts for the LLM (together, sometimes with tools, etc.) And one of the new things we’ve recently launched to support LLMs is the <a href=\"https://resources.wolframcloud.com/PromptRepository/\">Wolfram Prompt Repository</a>:</p>\n<p> <a href=\"https://resources.wolframcloud.com/PromptRepository/\"><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062723sec2img7-2.png' alt='Wolfram Prompt Repository' title='Wolfram Prompt Repository' width='620' height=''></a></p>\n<p>The Prompt Repository contains several kinds of prompts. The first are personas, which are used to “style” and otherwise inform chat interactions. But then there are two other types of prompts: function prompts, and modifier prompts.</p>\n<p>Function prompts are for getting the LLM to do something specific, like summarize a piece of text, or suggest a joke (it’s not terribly good at that). Modifier prompts are for determining how the LLM should modify its output, for example translating into a different human language, or keeping it to a certain length.</p>\n<p>You can pull in function prompts from the repository into a Chat Notebook by using <span class=\"kbd\"><kbd>!</kbd></span>, and modifier prompts using <span class=\"kbd\"><kbd>#</kbd></span>.

It’s often a challenge to know that something can be expressed in terms of special functions. But once one’s done this, one can immediately apply the independent knowledge that exists about the special functions.</p>\n<p>Even in <a href=\"https://reference.wolfram.com/legacy/v1/\">Version 1.0</a> we already supported many special functions. And over the years we’ve added support for many more—to the point where we now cover everything that might reasonably be considered a “classical” special function. But in recent years we’ve also been tackling more general special functions. They’re mathematically more complex, but each one we successfully cover makes a new collection of problems accessible to exact solution and reliable numerical and symbolic computation.</p>\n<p>Most of the “classic” special functions—like <a href=\"https://mathworld.wolfram.com/BesselFunction.html\">Bessel functions</a>, <a href=\"https://mathworld.wolfram.com/LegendreFunctionoftheFirstKind.html\">Legendre functions</a>, <a href=\"https://mathworld.wolfram.com/EllipticIntegral.html\">elliptic integrals</a>, etc.—are in the end univariate <a href=\"https://mathworld.wolfram.com/HypergeometricFunction.html\">hypergeometric functions</a>. But one important frontier in “general special functions” are those corresponding to bivariate hypergeometric functions. And already in <a href=\"https://reference.wolfram.com/legacy/v4/\">Version 4.0</a> (1999) we introduced one example of such as a function: <tt><a href=\"http://reference.wolfram.com/language/ref/AppellF1.html\">AppellF1</a></tt>. And, yes, it’s taken a while, but now in Version 13.3 we’ve finally finished doing the math and creating the algorithms to introduce <a href=\"https://reference.wolfram.com/language/ref/AppellF2.html\"><tt>AppellF2</tt></a>, <a href=\"https://reference.wolfram.com/language/ref/AppellF3.html\"><tt>AppellF3</tt></a> and <a href=\"https://reference.wolfram.com/language/ref/AppellF4.html\"><tt>AppellF4</tt></a>.</p>\n<p>On the face of it, it’s just another function—with lots of arguments—whose value we can find to any precision:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img1.png' alt='' title='' width='380' height='47'> </div>\n</p></div>\n<p>Occasionally it has a closed form:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img2.png' alt='' title='' width='392' height='81'> </div>\n</p></div>\n<p>But despite its mathematical sophistication, plots of it tend to look fairly uninspiring:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img3.png' alt='' title='' width='457' height='154'> </div>\n</p></div>\n<p>Series expansions begin to show a little more:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img4.png' alt='' title='' width='485' height='138'> </div>\n</p></div>\n<p>And ultimately this is a function that solves a pair of PDEs that can be seen as a generalization to two variables of the univariate hypergeometric ODE. So what other generalizations are possible? <a href=\"https://www.wolframalpha.com/input?i=Paul+Appell\">Paul Appell</a> spent many years around the turn of the twentieth century looking—and came up with just four, which as of Version 13.3 now all appear in the Wolfram Language, as <tt><a href=\"http://reference.wolfram.com/language/ref/AppellF1.html\">AppellF1</a></tt>, <a href=\"https://reference.wolfram.com/language/ref/AppellF2.html\"><tt>AppellF2</tt></a>, <a href=\"https://reference.wolfram.com/language/ref/AppellF3.html\"><tt>AppellF3</tt></a> and <a href=\"https://reference.wolfram.com/language/ref/AppellF4.html\"><tt>AppellF4</tt></a>.</p>\n<p>To make special functions useful in the Wolfram Language they need to be “knitted” into other capabilities of the language—from numerical evaluation to series expansion, calculus, equation solving, and integral transforms. And in Version 13.3 we’ve passed another special function milestone, around integral transforms. </p>\n<p>When I started using special functions in the 1970s the main source of information about them tended to be a small number of handbooks that had been assembled through decades of work. When we began to build Mathematica and what’s now the Wolfram Language, one of our goals was to subsume the information in such handbooks. And over the years that’s exactly what we’ve achieved—for integrals, sums, differential equations, etc. But one of the holdouts has been integral transforms for special functions. And, yes, we’ve covered a great many of these. But there are exotic examples that can often only “coincidentally” be done in closed form—and that in the past have only been found in books of tables.</p>\n<p>But now in Version 13.3 we can do cases like: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062123sec4img5.png' alt='' title='' width='349' height='121'> </div>\n</p></div>\n<p>And in fact we believe that in Version 13.3 we’ve reached the edge of what’s ever been figured out about <a href=\"https://mathworld.wolfram.com/LaplaceTransform.html\">Laplace transforms</a> for special functions. The most extensive handbook—finally published in 1973—runs to about 400 pages. A few years ago we could do about 55% of the forward Laplace transforms in the book, and 31% of the inverse ones. But now in Version 13.3 we can do 100% of the ones that we can verify as correct (and, yes, there are definitely some mistakes in the book). It’s the end of a long journey, and a satisfying achievement in the quest to make as much mathematical knowledge as possible automatically computable.</p>\n<h2 id=\"finite-fields!\">Finite Fields!</h2>\n<p>Ever since <a href=\"https://reference.wolfram.com/legacy/v1/\">Version 1.0</a> we’ve been able to do things like factoring polynomials modulo primes.

And we’re always looking for ways to share and communicate 3D geometry. Already back in the early 1990s we had experimental implementations of VR. But at the time there wasn’t anything like the kind of infrastructure for VR that would be needed to make this broadly useful. In the mid-2010s we then introduced VR functionality based on Unity—that provides powerful capabilities within the Unity ecosystem, but is not accessible outside.</p>\n<p>Today, however, it seems there are finally broad standards emerging for AR and VR. And so in Version 13.3 we’re able to begin delivering what we hope will provide widely accessible AR and VR deployment from the Wolfram Language. </p>\n<p>At a underlying level what we’re doing is to support the USD and GLTF geometry representation formats. But we’re also building a higher-level interface that allows anyone to “publish” 3D geometry for AR and VR.</p>\n<p>Given a piece of geometry (which for now can’t involve too many polygons), all you do is apply <a href=\"https://reference.wolfram.com/language/ref/ARPublish.html\"><tt>ARPublish</tt></a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062823ARpublishAimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062123sec8img1A.png' alt='' title='' width='229' height=''> </div>\n</p></div>\n<p>The result is a cloud object that has a certain underlying UUID, but is displayed in a notebook as a QR code. Now all you do is look at this QR code with your phone (or tablet, etc.) camera, and press the URL it extracts.</p>\n<p>The result will be that the geometry you published with <a href=\"https://reference.wolfram.com/language/ref/ARPublish.html\"><tt>ARPublish</tt></a> now appears in AR on your phone:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/triptych-AR-v2.png' alt='Augmented reality triptych' title='Augmented reality triptych' width='620' height=''></p>\n<p>Move your phone and you’ll see that your geometry has been realistically placed into the scene. You can also go to a VR “object” mode in which you can manipulate the geometry on your phone.</p>\n<p>“Under the hood” there are some slightly elaborate things going on—particularly in providing the appropriate data to different kinds of phones. But the result is a first step in the process of easily being able to get AR and VR output from the Wolfram Language—deployed in whatever devices support AR and VR.</p>\n<h2 id=\"getting-the-details-right:-the-continuing-story\">Getting the Details Right: The Continuing Story</h2>\n<p>In every version of Wolfram Language we add all sorts of fundamentally new capabilities. But we also work to fill in details of existing capabilities, continually pushing to make them as general, consistent and accurate as possible. In Version 13.3 there are many details that have been “made right”, in many different areas. </p>\n<p>Here’s one example: the comparison (and sorting) of <tt><a href=\"http://reference.wolfram.com/language/ref/Around.html\">Around</a></tt> objects. Here are 10 random “numbers with uncertainty”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img1.png' alt='' title='' width='579' height='45'> </div>\n</p></div>\n<p>These sort by their central value:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img2.png' alt='' title='' width='579' height='44'> </div>\n</p></div>\n<p>But if we look at these, many of their uncertainty regions overlap:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img3.png' alt='' title='' width='299' height='194'> </div>\n</p></div>\n<p>So when should we consider a particular number-with-uncertainty “greater than” another? In Version 13.3 we carefully take into account uncertainty when making comparisons. So, for example, this gives <tt><a href=\"http://reference.wolfram.com/language/ref/True.html\">True:</a></tt></p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img4.png' alt='' title='' width='276' height='43'> </div>\n</p></div>\n<p>But when there’s too big an uncertainty in the values, we no longer consider the ordering “certain enough”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img5.png' alt='' title='' width='276' height='43'> </div>\n</p></div>\n<p>Here’s another example of consistency: the applicability of <tt><a href=\"http://reference.wolfram.com/language/ref/Duration.html\">Duration</a></tt>. We introduced <tt><a href=\"http://reference.wolfram.com/language/ref/Duration.html\">Duration</a></tt> to apply to explicit time constructs, things like <tt><a href=\"http://reference.wolfram.com/language/ref/Audio.html\">Audio</a></tt> objects, etc. But in Version 13.3 it also applies to entities for which there’s a reasonable way to define a “duration”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img6.png' alt='' title='' width='388' height='58'> </div>\n</p></div>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img7_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img7.png' alt='' title='' width='362' height='62'> </div>\n</p></div>\n<p>Dates (and times) are complicated things—and we’ve put a lot of effort into handling them correctly and consistently in the Wolfram Language. One concept that we introduced a few years ago is date granularity: the (subtle) analog of numerical precision for dates. But at first only some date functions supported granularity; now in Version 13.3 all date functions include a <tt><a href=\"http://reference.wolfram.com/language/ref/DateGranularity.html\">DateGranularity</a></tt> option—so that granularity can consistently be tracked through all date-related operations:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img8_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img8.png' alt='' title='' width='377' height='55'> </div>\n</p></div>\n<p>Also in dates, something that’s been added, particularly for astronomy, is the ability to deal with “years” specified by real numbers:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img9.png' alt='' title='' width='491' height='57'> </div>\n</p></div>\n<p>And one consequence of this is that it becomes easier to make a plot of something like astronomical distance 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/43/2023/06/sw062223sec9img10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img10.png' alt='' title='' width='615' height='187'> </div>\n</p></div>\n<p>Also in astronomy, we’ve been steadily extending our capabilities to consistently fill in computations for more situations. In Version 13.3, for example, we can now compute sunrise, etc. not just from points on Earth, but from points anywhere in the solar system:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img11.png' alt='' title='' width='367' height='66'> </div>\n</p></div>\n<p>By the way, we’ve also made the computation of sunrise more precise. So now if you ask for the position of the Sun right at sunrise you’ll get a result like this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec9img12.png' alt='' title='' width='332' height='89'> </div>\n</p></div>\n<p>How come the altitude of the Sun is not zero at sunrise? That’s because the disk of the Sun is of nonzero size, and “sunrise” is defined to be when any part of the Sun pokes over the horizon.</p>\n<h2 id=\"even-easier-to-type:-affordances-for-wolfram-language-input\">Even Easier to Type: Affordances for Wolfram Language Input</h2>\n<p>Back in 1988 when what’s now Wolfram Language first existed, the only way to type it was like ordinary text. But gradually we’ve introduced more and more “affordances” to make it easier and faster to type correct Wolfram Language input. In 1996, with <a href=\"https://reference.wolfram.com/legacy/v3/\">Version 3</a>, we introduced automatic spacing (and spanning) for operators, as well as brackets that flashed when they matched—and things like -> being automatically replaced by <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''>. Then in 2007, with <a href=\"https://reference.wolfram.com/legacy/v6/\">Version 6</a>, we introduced—with some trepidation at first—syntax coloring. We’d had a way to request autocompletion of a symbol name all the way back to the beginning, but it’d never been good or efficient enough for us to make it happen all the time as you type. But in 2012, for <a href=\"https://reference.wolfram.com/legacy/v9/guide/Mathematica.html\">Version 9</a>, we created a much more elaborate autocomplete system—that was useful and efficient enough that we turned it on for all notebook input. A key feature of this autocomplete system was its context-sensitive knowledge of the Wolfram Language, and how and where different symbols and strings typically appear. Over the past decade, we’ve gradually refined this system to the point where I, for one, deeply rely on it.</p>\n<p>In recent versions, we’ve made other “typability” improvements. For example, in <a href=\"https://reference.wolfram.com/legacy/language/v12.3/\">Version 12.3</a>, we generalized the -> to <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> transformation to a whole collection of “auto operator renderings”. Then in <a href=\"https://reference.wolfram.com/legacy/language/v13/\">Version 13.0</a> we introduced “automatching” of brackets, in which, for example, if you enter <tt>[</tt> at the end of what you’re typing, you’ll automatically get a matching <tt>]</tt>. </p>\n<p>Making “typing affordances” work smoothly is a painstaking and tricky business. But in every recent version we’ve steadily been adding more features that—in very “natural” ways—make it easier and faster to type Wolfram Language input. </p>\n<p>In Version 13.3 one major change is an enhancement to autocompletion. Instead of just showing pure completions in which characters are appended to what’s already been typed, the autocompletion menu now includes “fuzzy completions” that fill in intermediate characters, change capitalization, etc.</p>\n<p>So, for example, if you type “<span class=\"computer-voice\">lp</span>” you now get <tt><a href=\"http://reference.wolfram.com/language/ref/ListPlot.html\">ListPlot</a></tt> as a completion (the little underlines indicate where the letters you actually type appear):</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec10img2B.png' alt='ListPlot autocompletion menu' title='ListPlot automcompletion menu' width='152' height=''> </p>\n<p>From a design point of view one thing that’s important about this is that it further removes the “short name” premium—and weights things even further on the side of wanting names that explain themselves when they’re read, rather than that are easy to type in an unassisted way. With the <a href=\"https://resources.wolframcloud.com/FunctionRepository/\">Wolfram Function Repository</a> it’s become increasingly common to want to type <tt><a href=\"http://reference.wolfram.com/language/ref/ResourceFunction.html\">ResourceFunction</a></tt>. And we’d been thinking that perhaps we should have a special, short notation for that. But with the new autocompletion, one can operationally just press three <nobr>keys—<span class=\"kbd\"><kbd>r</kbd><kbd>f</kbd><kbd>enter</kbd></span>—</nobr>to get to <tt><a href=\"http://reference.wolfram.com/language/ref/ResourceFunction.html\">ResourceFunction</a></tt>:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/rfmenu-v3.png' alt='ResourceFunction autocompletion menu' title='ResourceFunction autocompletion menu' width='163' height=''></p>\n<p>When one designs something and gets the design right, people usually don’t notice; things just “work as they expect”. But when there’s a design error, that’s when people notice—and are frustrated by—the design. But then there’s another case: a situation where, for example, there are two things that could happen, and sometimes one wants one, and sometimes the other. In doing the design, one has to pick a particular branch. And when this happens to be the branch people want, they don’t notice, and they’re happy. But if they want the other branch, it can be confusing and frustrating.</p>\n<p>In the design of the Wolfram Language one of the things that has to be chosen is the precedence for every operator: <em>a</em> + <em>b</em> × <em>c</em> means <em>a</em> + (<em>b</em> × <em>c</em>) because × has higher precedence than +. Often the correct order of precedences is fairly obvious. But sometimes it’s simply impossible to make everyone happy all the time. And so it is with <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> and <tt>&</tt>. It’s very convenient to be able to add <tt>&</tt> at the end of something you type, and make it into a pure function. But that means if you type <nobr><em>a</em> <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> <em>b</em> <tt>&</tt></nobr> it’ll turn the whole thing into a function: <tt><em>a</em> <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> <em>b</em> &</tt>. When functions have options, however, one often wants things like <em>name</em> <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> <em>function</em>. The natural tendency is to type this as <em>name</em> <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> <em>body</em> <tt>&</tt>. But this will mean (<em>name</em> <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> <em>body</em>) <tt>&</tt> rather than <em>name</em> <img style=\"margin-bottom: 0px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423plainarrow.png' alt='' title='' width='17' height=''> (<em>body</em> <tt>&</tt>). And, yes, when you try to run the function, it’ll notice it doesn’t have correct arguments and options specified. But you’d like to know that what you’re typing isn’t right as soon as you type it. And now in Version 13.3 we have a mechanism for that. As soon as you enter <tt>&</tt> to “end a function”, you’ll see the extent of the function flash:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec10img13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/purefunction-highlight-1-v2-1.gif' alt='' title='' width='555' height=''> </div>\n</p></div>\n<p>And, yup, you can see that’s wrong. Which gives you the chance to fix it as:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec10img13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/purefunction-highlight-2-v2-1.gif' alt='' title='' width='520' height=''> </div>\n</p></div>\n<p>There’s another <a href=\"https://www.wolfram.com/notebooks/\">notebook</a>-related update in Version 13.3 that isn’t directly related to typing, but will help in the construction of easy-to-navigate user interfaces. We’ve had <tt><a href=\"http://reference.wolfram.com/language/ref/ActionMenu.html\">ActionMenu</a></tt> since 2007—but it’s only been able to create one-level menus. In Version 13.3 it’s been extended to arbitrary hierarchical menus:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec10img15_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/action-menu-arrows.png' alt='' title='' width='577' height=''> </div>\n</p></div>\n<p>Again not directly related to typing, but now relevant to managing and editing code, there’s an update in Version 13.3 to package editing in the notebook interface. Bring up a .wl file and it’ll appear as a notebook. But its default toolbar is different from the usual notebook toolbar (and is newly designed in Version 13.3):</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec10img18.png' alt='New default toolbar' title='New default toolbar' width='603' height='51'></p>\n<p><tt style=\"font-weight: 600;\">Go To</tt> now gives you a way to immediately go to the definition of any function whose name matches what you type, as well as any section, etc.:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/WL-Toolbar2-v3.png' alt='Go To results' title='Go To results' width='480' height=''></p>\n<p>The numbers on the right here are code line numbers; you can also go directly to a specific line number by typing :<em>nnn</em>.</p>\n<h2 id=\"the-elegant-code-project\">The Elegant Code Project</h2>\n<p>One of the central goals—and achievements—of the Wolfram Language is to create a computational language that can be used not only as a way to tell computers what to do, but also as a way to communicate computational ideas for human consumption. In other words, Wolfram Language is intended not only to be written by humans (for consumption by computers), but also to be read by humans. </p>\n<p>Crucial to this is the broad consistency of the Wolfram Language, as well as its use of carefully chosen natural-language-based names for functions, etc. But what can we do to make Wolfram Language as easy and pleasant as possible to read? In the past we’ve balanced our optimization of the appearance of Wolfram Language between reading and writing. But in Version 13.3 we’ve got the beginnings of our Elegant Code project—to find ways to render Wolfram Language to be specifically optimized for reading.</p>\n<p>As an example, here’s a small piece of code (from my <em><a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/\">An Elementary Introduction to the Wolfram Language</a></em>), shown in the default way it’s rendered in notebooks:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img2.png' alt='' title='' width='487' height='18'> </div>\n</p></div>\n<p>But in Version 13.3 you can use <tt style=\"font-weight: 600;\">Format</tt> > <tt style=\"font-weight: 600;\">Screen Environment</tt> > <tt style=\"font-weight: 600;\">Elegant</tt> to set a notebook to use the current version of “elegant code”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img1.png' alt='' title='' width='487' height='15'> </div>\n</p></div>\n<p>(And, yes, this is what we&#8217;re actually using for code in this post, as well as some other recent ones.) So what’s the difference? First of all, we’re using a proportionally spaced font that makes the names (here of symbols) easy to “read like words”. And second, we’re adding space between these “words”, and graying back “structural elements” like <img loading='lazy' style=\"margin-bottom: -3px\"src='https://content.wolfram.com/sites/43/2023/06/sw062423leftbracket.png' alt='' title='' width='8' height=''> &#8230; <img loading='lazy' style=\"margin-bottom: -2px\"src='https://content.wolfram.com/sites/43/2023/06/sw062423rightbracket.png' alt='' title='' width='8' height=''> and <img loading='lazy' style=\"margin-bottom: -2px\"src='https://content.wolfram.com/sites/43/2023/06/sw062423leftbrace.png' alt='' title='' width='8' height=''> &#8230; <img loading='lazy' style=\"margin-bottom: -2px\"src='https://content.wolfram.com/sites/43/2023/06/sw062423rightbrace.png' alt='' title='' width='8' height=''>. When you write a piece of code, things like these structural elements need to stand out enough for you to “see they’re right”. But when you’re reading code, you don’t need to pay as much attention to them. Because the Wolfram Language is so based on “word-like” names, you can typically “understand what it’s saying” just by “reading these words”.</p>\n<p>Of course, making code “elegant” is not just a question of formatting; it’s also a question of what’s actually in the code. And, yes, as with writing text, it takes effort to craft code that “expresses itself elegantly”. But the good news is that the Wolfram Language—through its uniquely broad and high-level character—makes it surprisingly straightforward to create code that expresses itself extremely elegantly.</p>\n<p>But the point now is to make that code not only elegant in content, but also elegant in formatting. In technical documents it’s common to see math that’s at least formatted elegantly. But when one sees code, more often than not, it looks like something only a machine could appreciate. Of course, if the code is in a traditional programming language, it’ll usually be long and not really intended for human consumption. But what if it’s elegantly crafted Wolfram Language code? Well then we’d like it to look as attractive as text and math. And that’s the point of our Elegant Code project.</p>\n<p>There are many tradeoffs, and many issues to be navigated. But in Version 13.3 we’re definitely making progress. Here’s an example that doesn’t have so many “words”, but where the elegant code formatting still makes the “blocking” of the code more obvious:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img4.png' alt='' title='' width='363' height='67'> </div>\n</p></div>\n<p>Here’s a slightly longer piece of code, where again the elegant code formatting helps pull out “readable” words, as well as making the overall structure of the code more obvious: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423sec11img5.png' alt='' title='' width='385' height='92'> </div>\n</p></div>\n<p>Particularly in recent years, we’ve added many mechanisms to let one write Wolfram Language that’s easier to read. There are the auto operator renderings, like <tt>m[[i]]</tt> turning into <img style=\"margin-bottom: -4px\" loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423sec11imgmiEC.png' alt='' title='' width='36' height=''>.

Plotting the number of words that appear in the documentation in successive versions, we see a strong progressive increase:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec12img1.png' alt='Words graph' title='Words graph' width='431' height='261'></p>\n<p>But with all that documentation, and all those new things to be documented, the problem of appropriately crosslinking everything has increased. Even back in <a href=\"https://reference.wolfram.com/legacy/v1/\">Version 1.0</a>, when the documentation was a physical book, there were “See Also’s” between functions:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec12img2.png' alt='Versioni 1.0 documentation' title='Version 1.0 documentation' width='622' height='123'></p>\n<p>And by now there’s a complicated network of such See Also’s:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062223sec12img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062223sec12img4.png' alt='' title='' width='578' height='447'> </div>\n</p></div>\n<p>But that’s just the network of how functions point to functions. What about other kinds of constructs? Like formats, characters or entity types—or, for that matter, entries in the Wolfram Function Repository, <a href=\"https://reference.wolfram.com/language/guide/WolframDataRepository.html\">Wolfram Data Repository</a>, etc. Well, in Version 13.3 we’ve done a first iteration of crosslinking all these kinds of things.</p>\n<p>So here now are the &#8220;See Also&#8221; areas for <a href=\"https://reference.wolfram.com/language/ref/Graph.html\"><tt>Graph</tt></a> and <a href=\"https://reference.wolfram.com/language/ref/Molecule.html\"><tt>Molecule</tt></a>:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/seealso-graph.png' alt='Graph see also options' title='Graph see also options' width='620' height=''> </p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/seealso-molecule.png' alt='Molecule see also options' title='Molecule see also options' width='620' height=''> </p>\n<p>Not only are there functions here; there are also other kinds of things that a person (or AI) looking at these pages might find relevant. </p>\n<p>It’s great to be able to follow links, but sometimes it’s better just to have material immediately accessible, without following a link. Back in <a href=\"https://reference.wolfram.com/legacy/v1/\">Version 1.0</a> we made the decision that when a function inherits some of its options from a “base function” (say <tt><a href=\"http://reference.wolfram.com/language/ref/Plot.html\">Plot</a></tt> from <tt><a href=\"http://reference.wolfram.com/language/ref/Graphics.html\">Graphics</a></tt>), we only need to explicitly list the non-inherited option values. At the time, this was a good way to save a little paper in the printed book. But now the optimization is different, and finally in Version 13.3 we have a way to show “All Options”—tucked away so it doesn’t distract from the typically-more-important non-inherited options.</p>\n<p>Here’s the setup for <tt><a href=\"http://reference.wolfram.com/language/ref/Plot.html\">Plot</a></tt>.

It’s not yet realistic to do this at all well on anything but a high-end (and typically server) GPU-enabled machine. But in Version 13.3 there’s now a built-in function <a href=\"https://reference.wolfram.com/language/ref/ImageSynthesize.html\"><tt>ImageSynthesize</tt></a> that can get images synthesized, for now through an external API.</p>\n<p>You give text, and <a href=\"https://reference.wolfram.com/language/ref/ImageSynthesize.html\"><tt>ImageSynthesize</tt></a> will try to generate images for which that text is a description:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec13img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec13img1.png' alt='' title='' width='595' height='159'> </div>\n</p></div>\n<p>Sometimes these images will be directly useful in their own right, perhaps as “theming images” for documents or user interfaces.

The goal is to be able to compute with models of engineering and other systems that can be described by (potentially very large) collections of ordinary differential equations and their discrete analogs. Our separate <a href=\"https://www.wolfram.com/system-modeler/\">Wolfram System Modeler</a> product provides an IDE and GUI for graphically creating such models.</p>\n<p>For the past five years we’ve been able to do high-efficiency simulation of these models from within the Wolfram Language. And over the past few years we’ve been adding all sorts of higher-level functionality for programmatically creating models, and for systematically analyzing their behavior. A major focus in recent versions has been the synthesis of control systems, and various forms of controllers.</p>\n<p>Version 13.3 now tackles a different issue, which is the alignment of models with real-world systems. The idea is to have a model which contains certain parameters, and then to determine these parameters by essentially fitting the model’s behavior to observed behavior of a real-world system. </p>\n<p>Let’s start by talking about a simple case where our model is just defined by a single ODE:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img1.png' alt='' title='' width='435' height='138'> </div>\n</p></div>\n<p>This ODE is simple enough that we can find its analytical solution:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img2.png' alt='' title='' width='330' height='73'> </div>\n</p></div>\n<p>So now let’s make some “simulated real-world data” assuming <nobr><em>a</em> = 2,</nobr> and with some noise:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img4.png' alt='' title='' width='603' height='14'> </div>\n</p></div>\n<p>Here’s what the data looks like:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec14img5.png' alt='' title='' width='305' height='195'> </div>\n</p></div>\n<p>Now let’s try to “calibrate” our original model using this data.

And when one builds a test suite, one does it just by making a list of test objects. </p>\n<p>This makes a list of test objects (and, yes, there’s some trickiness because <a href=\"https://reference.wolfram.com/language/ref/TestCreate.html\"><tt>TestCreate</tt></a> needs to keep unevaluated the expression that’s going to be tested):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec15img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec15img4.png' alt='' title='' width='646' height='157'> </div>\n</p></div>\n<p>But given these tests, we can now generate a report from running them:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec15img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec15img5.png' alt='' title='' width='347' height='78'> </div>\n</p></div>\n<p><a href=\"https://reference.wolfram.com/language/ref/TestReport.html\"><tt>TestReport</tt></a> has various options that allow you to monitor and control the running of a test suite.

But a few years ago we started introducing capabilities for having the Wolfram Language ask questions of humans, and then assessing their answers. </p>\n<p>In recent versions we’ve been building up sophisticated ways to construct and deploy “quizzes” and other collections of questions. But one of the core issues is always how to determine whether a person has answered a particular question correctly. Sometimes that’s easy to determine. If we ask “What is 2 + 2?”, the answer better be “4” (or conceivably “four”). But what if we ask a question where the answer is some algebraic expression? The issue is that there may be many mathematically equal forms of that expression. And it depends on what exactly one’s asking whether one considers a particular form to be the “right answer” or not.</p>\n<p>For example, here we’re computing a derivative:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img1.png' alt='' title='' width='157' height='47'> </div>\n</p></div>\n<p>And here we’re doing a factoring problem:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img2.png' alt='' title='' width='178' height='44'> </div>\n</p></div>\n<p>These two answers are mathematically equal. And they’d both be “reasonable answers” for the derivative if it appeared as a question in a calculus course. But in an algebra course, one wouldn’t want to consider the unfactored form a “correct answer” to the factoring problem, even though it’s “mathematically equal”.</p>\n<p>And to deal with these kinds of issues, we’re introducing in Version 13.3 more detailed mathematical assessment functions. With a <tt>\"CalculusResult\"</tt> assessment function, it’s OK to give the unfactored form:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img3.png' alt='' title='' width='486' height='84'> </div>\n</p></div>\n<p>But with a <tt>\"PolynomialResult\"</tt> assessment function, the algebraic form of the expression has to be the same for it to be considered “correct”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img4.png' alt='' title='' width='507' height='84'> </div>\n</p></div>\n<p>There’s also another type of assessment function—<tt>\"ArithmeticResult\"</tt>—which only allows trivial arithmetic rearrangements, so that it considers 2 + 3 equivalent to 3 + 2, but doesn’t consider 2/3 equivalent to 4/6:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img5_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img5.png' alt='' title='' width='537' height='78'> </div>\n</p></div>\n<p>Here’s how you’d build a question with this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec16img6_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/QuestionObject-v2.png' alt='' title='' width='546' height=''> </div>\n</p></div>\n<p>And now if you type &#8220;2/3&#8221; it’ll say you’ve got it right, but if you type &#8220;4/6&#8221; it won’t.

And certainly for me it’s been critical in a whole range of research projects I’ve done. I currently have 156 cores routinely available in my “home” setup, distributed across 6 machines. It’s sometimes challenging from a system administration point of view to keep all those machines and their networking running as one wants. And one of the things we’ve been doing in recent versions—and now completed in Version 13.3—is to make it easier from within the Wolfram Language to see and manage what’s going on.</p>\n<p>It all comes down to specifying the configuration of kernels. And in Version 13.3 that’s now done using symbolic <tt><a href=\"http://reference.wolfram.com/language/ref/KernelConfiguration.html\">KernelConfiguration</a></tt> objects. Here’s an example of one:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062623sec17img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec17img1-edit.png' alt='' title='' width='481' height=''> </div>\n</p></div>\n<p>There’s all sorts of information in the kernel configuration object:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062623sec17img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec17img2-edit2.png' alt='' title='' width='579' height=''> </div>\n</p></div>\n<p>It describes “where” a kernel with that configuration will be, how to get to it, and how it should be launched. The kernel might just be local to your machine. Or it might be on a remote machine, accessible through <span class=\"computer-voice\">ssh</span>, or <span class=\"computer-voice\">https</span>, or our own <span class=\"computer-voice\">wstp</span> (<a href=\"https://www.wolfram.com/wstp/\">Wolfram Symbolic Transport Protocol</a>) or <span class=\"computer-voice\">lwg</span> (<a href=\"https://www.wolfram.com/lightweight-grid-manager/\">Lightweight Grid</a>) protocols.</p>\n<p>In Version 13.3 there’s now a GUI for setting up kernel configurations: </p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec17img3A-edit.png' alt='Kernel configuration editor' title='Kernal configuration editor' width='547' height=''> </p>\n<p>The <a href=\"https://reference.wolfram.com/language/ref/menuitem/KernelConfigurationOptions.html\">Kernel Configuration Editor</a> lets you enter all the details that are needed, about network connections, authentication, locations of executables, etc.</p>\n<p>But once you’ve set up a <tt><a href=\"http://reference.wolfram.com/language/ref/KernelConfiguration.html\">KernelConfiguration</a></tt> object, that’s all you ever need—for example to say “where” to do a remote evaluation:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062623sec17img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec17img4-edit.png' alt='' title='' width='605' height=''> </div>\n</p></div>\n<p><tt><a href=\"http://reference.wolfram.com/language/ref/ParallelMap.html\">ParallelMap</a></tt> and other parallel functions then just work by doing their computations on kernels specified by a list of <tt><a href=\"http://reference.wolfram.com/language/ref/KernelConfiguration.html\">KernelConfiguration</a></tt> objects.

Direct Access to External Libraries</h2>\n<p>Let’s say you’ve got an external library written in C—or in some other language that can compile to a C-compatible library. In Version 13.3 there’s now foreign function interface (FFI) capability that allows you to directly call any function in the external library just using Wolfram Language code. </p>\n<p>Here’s a very trivial C function:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img0.png' alt='Trivial C function' title='Trivial C function' width='145' height=''></p>\n<p>This function happens to be included in compiled form in the <tt>compilerDemoBase</tt> library that’s part of Wolfram Language documentation. Given this library, you can use <a href=\"https://reference.wolfram.com/language/ref/ForeignFunctionLoad.html\"><tt>ForeignFunctionLoad</tt></a> to load the library and create a Wolfram Language function that directly calls the C <span class=\"computer-voice\">addone</span> function. All you need do is specify the library and C function, and then give the type signature for the function:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img1.png' alt='' title='' width='598' height='78'> </div>\n</p></div>\n<p>Now <tt style=\"font-weight: 600;\">ff</tt> is a Wolfram Language function that calls the C <span class=\"computer-voice\">addone</span> function:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img2.png' alt='' title='' width='95' height='43'> </div>\n</p></div>\n<p>The C function <span class=\"computer-voice\">addone</span> happens to have a particularly simple type signature, that can immediately be represented in terms of compiler types that have direct analogs as Wolfram Language expressions. But in working with low-level languages, it’s very common to have to deal directly with raw memory, which is something that never happens when you’re purely working at the Wolfram Language level.</p>\n<p>So, for example, in the OpenSSL library there’s a function called <span class=\"computer-voice\">RAND_bytes</span>, whose C type signature is:</p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img2X.png' alt='RAND_bytes' title='RAND_bytes' width='320' height=''></p>\n<p>And the important thing to notice is that this contains a pointer to a buffer <span class=\"computer-voice\">buf</span> that gets filled by <span class=\"computer-voice\">RAND_bytes</span>. If you were calling <span class=\"computer-voice\">RAND_bytes</span> from C, you’d first allocate memory for this buffer, then—after calling <span class=\"computer-voice\">RAND_bytes</span>—read back whatever was written to the buffer. So how can you do something analogous when you’re calling <span class=\"computer-voice\">RAND_bytes</span> using <a href=\"https://reference.wolfram.com/language/ref/ForeignFunction.html\"><tt>ForeignFunction</tt></a> in Wolfram Language? In Version 13.3 we’re introducing a family of constructs for working with pointers and raw memory. </p>\n<p>So, for example, here’s how we can create a Wolfram Language foreign function corresponding to <span class=\"computer-voice\">RAND_bytes</span>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img3.png' alt='' title='' width='551' height='113'> </div>\n</p></div>\n<p>But to actually use this, we need to be able to allocate the buffer, which in Version 13.3 we can do with <a href=\"https://reference.wolfram.com/language/ref/RawMemoryAllocate.html\"><tt>RawMemoryAllocate</tt></a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062323sec18img4.png' alt='' title='' width='389' height='108'> </div>\n</p></div>\n<p>This creates a buffer that can store 10 unsigned chars.

But <a href=\"https://reference.wolfram.com/language/ref/RawMemoryAllocate.html\"><tt>RawMemoryAllocate</tt></a> creates a <a href=\"https://reference.wolfram.com/language/ref/ManagedObject.html\"><tt>ManagedObject</tt></a>, which keeps track of whether it’s being referenced, and automatically frees the memory that’s been allocated when nothing references it anymore.</p>\n<p>Long ago languages like BASIC provided PEEK and POKE functions for reading and writing raw memory. It was always a dangerous thing to do—and it’s still dangerous. But it’s somewhat higher level in Wolfram Language, where in Version 13.3 there are now functions like <tt><a href=\"http://reference.wolfram.com/language/ref/RawMemoryRead.html\">RawMemoryRead</a></tt> and <a href=\"https://reference.wolfram.com/language/ref/RawMemoryWrite.html\"><tt>RawMemoryWrite</tt></a>. (For writing data into a buffer, <a href=\"https://reference.wolfram.com/language/ref/RawMemoryExport.html\"><tt>RawMemoryExport</tt></a> is also relevant.)</p>\n<p>Most of the time it’s very convenient to deal with memory-managed <a href=\"https://reference.wolfram.com/language/ref/ManagedObject.html\"><tt>ManagedObject</tt></a> constructs. But for the full low-level experience, Version 13.3 provides <a href=\"https://reference.wolfram.com/language/ref/UnmanageObject.html\"><tt>UnmanageObject</tt></a>, which disconnects automatic memory management for a managed object, and requires you to explicitly use <a href=\"https://reference.wolfram.com/language/ref/RawMemoryFree.html\"><tt>RawMemoryFree</tt></a> to free it.</p>\n<p>One feature of C-like languages is the concept of a function pointer. And normally the function that the pointer is pointing to is just something like a C function. But in Version 13.3 there’s another possibility: it can be a function defined in Wolfram Language.

But if you’re calling C-like functions a great many times, you’ll sometimes want to do it using compiled Wolfram Language code. And you can do this using the <a href=\"https://reference.wolfram.com/language/ref/LibraryFunctionDeclaration.html\"><tt>LibraryFunctionDeclaration</tt></a> mechanism that was introduced in Version 13.1. It’ll be more complicated to set up, and it’ll require an explicit compilation step, but there’ll be slightly less “overhead” in calling the external functions.</p>\n<h2 id=\"the-advance-of-the-compiler-continues\">The Advance of the Compiler Continues</h2>\n<p>For several years we’ve had an ambitious project to develop a large-scale compiler for the Wolfram Language. And in each successive version we’re further extending and enhancing the compiler. In Version 13.3 we’ve managed to compile more of the compiler itself (which, needless to say, is written in Wolfram Language)—thereby making the compiler more efficient in compiling code. We’ve also enhanced the performance of the code generated by the compiler—particularly by optimizing memory management done in the compiled code.</p>\n<p>Over the past several versions we’ve been steadily making it possible to compile more and more of the Wolfram Language. But it’ll never make sense to compile everything—and in Version 13.3 we’re adding <a href=\"https://reference.wolfram.com/language/ref/KernelEvaluate.html\"><tt>KernelEvaluate</tt></a> to make it more convenient to call back from compiled code to the Wolfram Language kernel. </p>\n<p>Here’s an example:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062423sec19img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423sec19img1.png' alt='' title='' width='605' height='127'> </div>\n</p></div>\n<p>We’ve got an argument <em>n</em> that’s declared as being of type <tt style=\"font-weight: 600;\"><a href=\"https://reference.wolfram.com/language/ref/compiledtype/MachineInteger.html\">MachineInteger</a></tt>. Then we’re doing a computation on <em>n</em> in the kernel, and using <tt><a href=\"http://reference.wolfram.com/language/ref/TypeHint.html\">TypeHint</a></tt> to specify that its result will be of type <tt style=\"font-weight: 600;\"><a href=\"https://reference.wolfram.com/language/ref/compiledtype/MachineInteger.html\">MachineInteger</a></tt>. There’s at least arithmetic going on outside the <a href=\"https://reference.wolfram.com/language/ref/KernelEvaluate.html\"><tt>KernelEvaluate</tt></a> that can be compiled, even though the <a href=\"https://reference.wolfram.com/language/ref/KernelEvaluate.html\"><tt>KernelEvaluate</tt></a> is just calling uncompiled code:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/06/sw062423sec19img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/06/sw062423sec19img2.png' alt='' title='' width='98' height='43'> </div>\n</p></div>\n<p>There are other enhancements to the compiler in Version 13.3 as well. For example, <tt><a href=\"http://reference.wolfram.com/language/ref/Cast.html\">Cast</a></tt> now allows data types to be cast in a way that directly emulates what the C language does. There’s also now <a href=\"https://reference.wolfram.com/language/ref/SequenceType.html\"><tt>SequenceType</tt></a>, which is a type analogous to the Wolfram Language <tt><a href=\"http://reference.wolfram.com/language/ref/Sequence.html\">Sequence</a></tt> construct—and able to represent an arbitrary-length sequence of arguments to a function. </p>\n<h2 id=\"and-much-more...\">And Much More&#8230;</h2>\n<p>In addition to everything we’ve already discussed here, there are lots of other updates and enhancements in Version 13.3—as well as thousands of bug fixes. </p>\n<p>Some of the additions fill out corners of functionality, adding completeness or consistency. Statistical fitting functions like <tt><a href=\"http://reference.wolfram.com/language/ref/LinearModelFit.html\">LinearModelFit</a></tt> now accept input in all various association etc. forms that machine learning functions like <tt><a href=\"http://reference.wolfram.com/language/ref/Classify.html\">Classify</a></tt> accept. <tt><a href=\"http://reference.wolfram.com/language/ref/TourVideo.html\">TourVideo</a></tt> now lets you “tour” <tt><a href=\"http://reference.wolfram.com/language/ref/GeoGraphics.html\">GeoGraphics</a></tt>, with waypoints specified by geo positions. <tt><a href=\"http://reference.wolfram.com/language/ref/ByteArray.html\">ByteArray</a></tt> now supports the “corner case” of zero-length byte arrays. The compiler can now handle byte array functions, and additional string functions. Nearly 40 additional special functions can now handle numeric interval computations. <tt><a href=\"http://reference.wolfram.com/language/ref/BarcodeImage.html\">BarcodeImage</a></tt> adds support for UPCE and Code93 barcodes. <tt><a href=\"http://reference.wolfram.com/language/ref/SolidMechanicsPDEComponent.html\">SolidMechanicsPDEComponent</a></tt> adds support for the <a href=\"https://en.wikipedia.org/wiki/Yeoh_hyperelastic_model\" target=\"_blank\" rel=\"noopener\">Yeoh hyperelastic model</a>. And—twenty years after we first introduced export of SVG, there’s now built-in support for import of SVG not only to raster graphics, but also to vector graphics.</p>\n<p>There are new “utility” functions like <a href=\"https://reference.wolfram.com/language/ref/RealValuedNumberQ.html\"><tt>RealValuedNumberQ</tt></a> and <a href=\"https://reference.wolfram.com/language/ref/RealValuedNumericQ.html\"><tt>RealValuedNumericQ</tt></a>. There’s a new function <a href=\"https://reference.wolfram.com/language/ref/FindImageShapes.html\"><tt>FindImageShapes</tt></a> that begins the process of systematically finding geometrical forms in images. There are a number of new data structures—like <a href=\"https://reference.wolfram.com/language/ref/datastructure/SortedKeyStore\"><tt>\"SortedKeyStore\"</tt></a> and <a href=\"https://reference.wolfram.com/language/ref/datastructure/CuckooFilter\"><tt>\"CuckooFilter\"</tt></a>. </p>\n<p>There are also functions whose algorithms—and output—have been improved. <tt><a href=\"http://reference.wolfram.com/language/ref/ImageSaliencyFilter.html\">ImageSaliencyFilter</a></tt> now uses new machine-learning-based methods. <tt><a href=\"http://reference.wolfram.com/language/ref/RSolveValue.html\">RSolveValue</a></tt> gives cleaner and smaller results for the important case of linear difference equations with constant coefficients.</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<div class=\"bottomstripe\">\n<a href=\"https://wolfram.com/get-upgrade/\"><strong>Download your 13.3 now! »&nbsp;</strong> (It’s already live in the Wolfram Cloud!)</a>\n</div>\n",

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=''/></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=''/></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=''/></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=''/></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=''/></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> (&#8220;quote&#8221;) to get a &#8220;side chat&#8221; cell (in a Chat-Enabled Notebook, it&#8217;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=''/></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=''/></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=''/></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=''/></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=''/></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=''/></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=''/></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=''/></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=''> </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=''/></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> &#8230; <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=''/></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=''/></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=''/></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=''/></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=''/></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=''/></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=''/></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=''/></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=''/></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",

And one might wonder why, if one has a description for a prompt, one can’t just use that description directly, rather than having to store a prewritten prompt. Well, sometimes just using the description will indeed work fine. But often it won’t. Sometimes that’s because one needs to clarify further what one wants. Sometimes it’s because there are <a href='https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/#how-it-works%E2%80%94and-wrangling-the-ai'>not-immediately-obvious corner cases to cover</a>. And sometimes there’s just a certain amount of “LLM wrangling” to be done. And this all adds up to the need to do at least some “prompt engineering” on almost any prompt.</p>\n<p>The <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/YesNo/'>YesNo</a></span> modifier prompt from above is currently fairly simple:</p>\n<p></p>\n<table class='InCell'>\n<tbody>\n<tr>\n<td colspan='1' rowspan='1' class='Input'>\n<div>\n\t\t\t\t\t<img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg12.png\" alt='' title='' width='550' height='94' />\n\t\t\t\t</div>\n<div class='IFL' data-src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg12a_copy.txt\">\n\t\t\t\t\t<span class='close' id='5_out'>&amp;#10005</span></p>\n<pre class='text' id='5_out_text'></pre>\n</p></div>\n</td>\n</tr>\n</tbody>\n</table>\n<p></p>\n<p>But it’s still already complicated enough one that doesn’t want to have to repeat it every time one’s trying to force a yes/no answer. And no doubt there’ll be subsequent versions of this prompt (that, yes, will have <a href='https://reference.wolfram.com/language/guide/WolframResourceSystem.html'>versioning handled seamlessly</a> by the Prompt Repository) that will get increasingly elaborate, as more cases show up, and more prompt engineering gets done to address them. </p>\n<p>Many of the prompts in the Prompt Repository even now are considerably more complicated. Some contain typical “general prompt engineering”, but others contain for example special information that the LLM doesn’t intrinsically know, or <a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/#functions-from-examples'>detailed examples</a> that home in on what one wants to have happen.</p>\n<p>In the simplest cases, prompts (like the <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/YesNo/'>YesNo</a></span> one above) are just plain pieces of text. But often they contain parameters, or have additional computational or other content. And a key feature of the Wolfram Prompt Repository is that it can handle this ancillary material, ultimately by representing everything using <a href='https://www.wolfram.com/language/fast-introduction-for-programmers/en/symbolic-expressions/'>Wolfram Language symbolic expressions</a>.</p>\n<p>As we discussed in connection with <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMFunction</a></tt>, etc. <a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>in another post</a>, the core “textual” part of a prompt is represented by a symbolic <tt><a href='http://reference.wolfram.com/language/ref/StringTemplate.html'>StringTemplate</a></tt> that immediately allows positional or named parameters. Then there can be an interpreter that applies a Wolfram Language <tt><a href='http://reference.wolfram.com/language/ref/Interpreter.html'>Interpreter</a></tt> function to the raw textual output of the LLM—transforming it from plain text to a computable symbolic expression. More sophisticatedly, there can also be specifications of tools that the LLM can call (represented symbolically as <a href=\"https://reference.wolfram.com/language/ref/LLMTool.html\"><tt>LLMTool</tt></a> constructs), as well as other information about the required LLM configuration (represented by an <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMConfiguration</a></tt> object). But the key point is that all of this is automatically “packaged up” in the Prompt Repository. </p>\n<p>But what actually is the Wolfram Prompt Repository? Well, ultimately it’s just part of the general <a href='https://resources.wolframcloud.com/'>Wolfram Resource System</a>—the same one that’s used for 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>, <a href='https://resources.wolframcloud.com/NeuralNetRepository/'>Wolfram Neural Net Repository</a>, <a href='https://notebookarchive.org/'>Wolfram Notebook Archive</a>, and many other things. </p>\n<p>And so, for example, the <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/Yoda/'>&quot;Yoda&quot;</a></span> prompt is in the end represented by a symbolic <tt><a href='http://reference.wolfram.com/language/ref/ResourceObject.html'>ResourceObject</a></tt> that’s part of the Resource System:</p>\n<p></p>\n<table class='InCell'>\n<tbody>\n<tr>\n<td colspan='1' rowspan='1' class='Input'>\n<div>\n\t\t\t\t\t<img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg13.png\" alt='' title='' width='550' height='101' />\n\t\t\t\t</div>\n<div class='IFL' data-src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg13a_copy.txt\">\n\t\t\t\t\t<span class='close' id='6_out'>&amp;#10005</span></p>\n<pre class='text' id='6_out_text'></pre>\n</p></div>\n</td>\n</tr>\n</tbody>\n</table>\n<p></p>\n<p>Open up the display of this resource object, and we’ll immediately see various pieces of metadata (and a link to documentation), as well as the ultimate canonical UUID of the object:</p>\n<p></p>\n<table class='InCell'>\n<tbody>\n<tr>\n<td colspan='1' rowspan='1' class='Input'>\n<div>\n\t\t\t\t\t<img src=\"https://content.wolfram.com/sites/43/2023/06/sw053123promptrepoimg14b.png\" alt='' title='' width='603' height='176' />\n\t\t\t\t</div>\n<div class='IFL' data-src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg14a_copy.txt\">\n\t\t\t\t\t<span class='close' id='7_out'>&amp;#10005</span></p>\n<pre class='text' id='7_out_text'></pre>\n</p></div>\n</td>\n</tr>\n</tbody>\n</table>\n<p></p>\n<p>Everything that needs to use the prompt—Chat Notebooks, <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMPrompt</a></tt>, <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMResourceFunction</a></tt>, etc.—just works by accessing appropriate parts of the <tt><a href='http://reference.wolfram.com/language/ref/ResourceObject.html'>ResourceObject</a></tt>, so that for example the “hero image” (used for the persona icon) is retrieved like this:</p>\n<p></p>\n<table class='InCell'>\n<tbody>\n<tr>\n<td colspan='1' rowspan='1' class='Input'>\n<div>\n\t\t\t\t\t<img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg15.png\" alt='' title='' width='622' height='137' />\n\t\t\t\t</div>\n<div class='IFL' data-src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg15a_copy.txt\">\n\t\t\t\t\t<span class='close' id='8_out'>&amp;#10005</span></p>\n<pre class='text' id='8_out_text'></pre>\n</p></div>\n</td>\n</tr>\n</tbody>\n</table>\n<p></p>\n<p>There’s a lot of important infrastructure that “comes for free” from the general Wolfram Resource System—like efficient caching, automatic updating, documentation access, etc. And things like <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMPrompt</a></tt> follow the exact same approach as things like <tt><a href='http://reference.wolfram.com/language/ref/NetModel.html'>NetModel</a></tt> in being able to immediately reference entries in a repository.</p>\n<h2 id='what&rsquo;s-in-the-prompt-repository-so-far'>What&rsquo;s in the Prompt Repository So Far</h2>\n<p>We haven’t been working on the Wolfram Prompt Repository for very long, and we’re just opening it up for outside contributions now.

Others make use of common-sense knowledge. And some are just fun. But, yes, writing good prompts is hard—and what’s in the Prompt Repository will gradually improve. And when there are bugs, they can be pretty weird. Like <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/PunAbout/'>PunAbout</a></span> is supposed to generate a pun about some topic, but here it decides to protest and say it must generate three:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg39.png\" alt='Parrot' title='Parrot' width='605' height='' /></p>\n<p>The final category of prompts currently in the Prompt Repository are <a href='https://resources.wolframcloud.com/PromptRepository/category/modifier-prompts'>modifier prompts</a>, intended as a way to modify the output generated by the LLM. Sometimes modifier prompts can be essentially textual:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg40.png\" alt='How many legs does a spider have?' title='How many legs does a spider have?' width='605' height='' /></p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg41.png\" alt='How many legs does a spider have?' title='How many legs does a spider have?' width='605' height='' /></p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg42.png\" alt='How many legs does a spider have?' title='How many legs does a spider have?' width='605' height='' /></p>\n<p>But often modifier prompts are intended to create output in a particular form, suitable, for example, for interpretation by an interpreter in <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMFunction</a></tt>, etc.:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg43.png\" alt='How many legs does a spider have?' title='How many legs does a spider have?' width='605' height='' /></p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg44.png\" alt='Number of legs for the 5 common invertebrates' title='Number of legs for the 5 common invertebrates' width='605' height='' /></p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg45.png\" alt='Are AIs good?' title='Are AIs good?' width='605' height='' /></p>\n<p>So far the modifier prompts in the Prompt Repository are fairly simple. But once there are prompts that make use of tools (i.e. call back into Wolfram Language during the generation process) we can expect modifier prompts that are much more sophisticated, useful and robust.</p>\n<h2 id='adding-your-own-prompts'>Adding Your Own Prompts</h2>\n<p>The Wolfram Prompt Repository is set up to be a curated public collection of prompts where it’s easy for anyone to submit a new prompt. But—as we’ll explain—you can also use the framework of the Prompt Repository to store “private” prompts, or share them with specific groups.</p>\n<p>So how do you define a new prompt in the Prompt Repository framework? The easiest way is to fill out a Prompt Resource Definition Notebook:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg46.png\" alt='Prompt Resource Definition Notebook' title='Prompt Resource Definition Notebook' width='528' height='auto' /></p>\n<p>You can get this notebook <a href='https://resources.wolframcloud.com/PromptRepository/Unnamed-Prompt.nb'>here</a>, or from the <tt>Submit a Prompt</tt> button at the top of the Prompt Repository website, or by evaluating <a href=\"https://reference.wolfram.com/language/ref/CreateNotebook.html\"><tt>CreateNotebook</a>[\"PromptResource\"]</tt>.</p>\n<p>The setup is directly analogous to the ones for the <a href='https://resources.wolframcloud.com/FunctionRepository'>Wolfram Function Repository</a>, <a href='https://datarepository.wolframcloud.com/'>Wolfram Data Repository</a>, <a href='https://resources.wolframcloud.com/NeuralNetRepository'>Wolfram Neural Net Repository</a>, etc. And once you’ve filled out the Definition Notebook, you’ve got various choices:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg47.png\" alt='Definition Notebook deployment options' title='Definition Notebook deployment options' width='272' height='' /></p>\n<p><tt>Submit to Repository</tt> sends the prompt to our curation team for our official Wolfram Prompt Repository; <a href=\"https://reference.wolfram.com/language/ref/Deploy.html\"><tt>Deploy</tt></a> deploys it for your own use, and for people (or AIs) you choose to share it with. If you’re using the prompt “privately”, you can refer to it using its URI or other identifier (if you use <tt><a href='http://reference.wolfram.com/language/ref/ResourceRegister.html'>ResourceRegister</a></tt> you can also just refer to it by the name you give it). </p>\n<p>OK, so what do you need to specify in the Definition Notebook? The most important part is the actual prompt itself. And quite often the prompt may just be a (carefully crafted) piece of plain text. But ultimately—<a href=\"https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/#how-it-all-works\">as discussed elsewhere</a>—a prompt is a symbolic template, that can include parameters. And you can insert parameters into a prompt using “template slots”:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/05/sw053123promptrepoimg48.png\" alt='Template slots' title='Template slots' width='272' height='' /></p>\n<p>(<tt>Template Expression</tt> lets you insert Wolfram Language code that will be evaluated when the prompt is applied—so you can for example include the current time with <tt><a href='http://reference.wolfram.com/language/ref/Now.html'>Now</a></tt>.)</p>\n<p>In simple cases, all you’ll need to specify is the “pure prompt”. But in more sophisticated cases you’ll also want to specify some “outside the prompt” information—and there are some sections for this in the Definition Notebook: </p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/06/sw053123promptrepoimg49a.png\" alt='Definition Notebook sections' title='Definition Notebook sections' width='480' height='' /></p>\n<p>Chat-Related Features is most relevant for personas:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/06/sw053123promptrepoimg50a.png\" alt='Chat features' title='Chat features' width='480' height='' /></p>\n<p>You can give an icon that will appear in Chat Notebooks for that persona. And then you can give Wolfram Language functions which are to be applied to the contents of each chat cell before it is fed to the LLM (“Cell Processing Function”), and to the output generated by the LLM (“Cell Post Evaluation Function”). These functions are useful in transforming material to and from the plain text consumed by the LLM, and supporting richer display and computational structures.</p>\n<p>Programmatic Features is particularly relevant for function prompts, and for the way prompts are used in <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMResourceFunction</a></tt> etc.:</p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/06/sw053123promptrepoimg51c.png\" alt='Programmatic Features' title='Programmatic Features' width='480' height='' /></p>\n<p>There’s “function-oriented documentation” (analogous to what’s used for built-in Wolfram Language functions, or for functions in the Wolfram Function Repository). And then there’s the Output Interpreter: a function to be applied to the textual output of the LLM, to generate the actual expression that will be returned by <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMResourceFunction</a></tt>, or for formatting in a Chat Notebook.</p>\n<p>What about the LLM Configuration section? </p>\n<p><img src=\"https://content.wolfram.com/sites/43/2023/06/sw053123promptrepoimg52a.png\" alt='LLM configuration options' title='LLM configuration options' width='480' height='' /></p>\n<p>The first thing it does is to define tools that can be requested by the LLM when this prompt is used. We’ll discuss tools in another post. But as we’ve mentioned several times, they’re a way of having the LLM call Wolfram Language to get particular computational results that are then returned to the LLM. The other part of the LLM Configuration section is a more general <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMConfiguration</a></tt> specification, which can include “temperature” settings, the requirement of using a particular underlying model (e.g. GPT-4), etc.</p>\n<p>What else is in the Definition Notebook? There are two main documentation sections: one for Chat Examples, and one for Programmatic Examples. Then there are various kinds of metadata. </p>\n<p>Of course, at the very top of the Definition Notebook there’s another very important thing: the name you specify for the prompt. And here—with the initial prompts we’ve put into the Prompt Repository—we’ve started to develop some conventions. Following typical Wolfram Language usage we’re “camel-casing” names (so it’s <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/TitleSuggest/'>&quot;TitleSuggest&quot;</a></span> not <span class=\"promptformatted\">&quot;title suggest&quot;</span>). Then we try to use different grammatical forms for different kinds of prompts. For personas we try to use noun phrases (like <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/Cheerleader/'>&quot;Cheerleader&quot;</a></span> or <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/SommelierBot/'>&quot;SommelierBot&quot;</a></span>). For functions we usually try to use verb phrases (like <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/Summarize/'>&quot;Summarize&quot;</a></span> or <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/HypeUp/'>&quot;HypeUp&quot;</a></span>). And for modifiers we try to use past-tense verb forms (like <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/Translated/'>&quot;Translated&quot;</a></span> or <span class=\"promptformatted\"><a href='https://resources.wolframcloud.com/PromptRepository/resources/HaikuStyled/'>&quot;HaikuStyled&quot;</a></span>). </p>\n<p>The overall goal with prompt names—like with ordinary Wolfram Language function names—is to provide a summary of what the prompt does, in a form that’s short enough that it appears a bit like a word in computational language input, chats, etc.</p>\n<p>OK, so let’s say you’ve filled out a Definition Notebook, and you <a href=\"https://reference.wolfram.com/language/ref/Deploy.html\"><tt>Deploy</tt></a> it. You’ll get a webpage that includes the documentation you’ve given—and looks pretty much like any of the pages in the Wolfram Prompt Repository. And now if you want to use the prompt, you can just click the appropriate place on the webpage, and you’ll get a copyable version that you can immediately paste into an input cell, a chat cell, etc. (Within a Chat Notebook there’s an even more direct mechanism: in the chat icon menu, go to <tt>Add & Manage Personas</tt>, and when you browse the Prompt Repository, there’ll be an <span class=\"kbd\"><kbd>Install</kbd></span> button that will automatically install a persona.)</p>\n<h2 id='a-language-of-prompts'>A Language of Prompts</h2>\n<p>LLMs fundamentally deal with natural language of the kind we humans normally use. But when we set up a named prompt we’re in a sense defining a “<a href='https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/#the-concept-of-concepts'>higher-level word</a>” that can be used to “communicate” with the LLM—at the least with the kind of “harness” that <tt><a href='https://writings.stephenwolfram.com/2023/05/the-new-world-of-llm-functions-integrating-llm-technology-into-the-wolfram-language/'>LLMFunction</a></tt>, Chat Notebooks, etc. provide. And we can then imagine in effect “talking in prompts” and for example building up more and more levels of prompts.</p>\n<p>Of course, we already have a major example of something that at least in outline is similar: the way in which over the past few decades we’ve been able to progressively <a href='https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/'>construct a whole tower of functionality</a> from the <a href='https://reference.wolfram.com/language/'>built-in functions in the Wolfram Language</a>. There’s an important difference, however: in defining built-in functions we’re always working on “solid ground”, with precise (carefully designed) computational specifications for what we’re doing. In setting up prompts for an LLM, try as we might to “write the prompts well” we’re in a sense ultimately “at the mercy of the LLM” and how it chooses to handle things.</p>\n<p>It feels in some ways like the difference between dealing with engineering systems and with human organizations. In both cases one can set up plans and procedures for what should happen. In the engineering case, however, one can expect that (at least at the level of individual operations) the system will do exactly as one says. In the human case—well, all kinds of things can happen. That is not to say that amazing results can’t be achieved by human organizations; history clearly shows they can.</p>\n<p>But—as someone who’s managed <a href='https://www.wolfram.com/'>(human) organizations</a> now for more than four decades—I think I can say the “rhythm” and practices of dealing with human organizations differ in significant ways from those for technological ones. There’s still a definite pattern of what to do, but it’s different, with a different way of going back and forth to get results, different approaches to “debugging”, etc. </p>\n<p>How will it work with prompts? It’s something we still need to get used to. But for me there’s immediately another useful “comparable”. Back in the early 2000s we’d had a decade or two of experience in developing what’s now Wolfram Language, with its precise formal specifications, carefully designed with consistency in mind. But then we started working on <a href='https://www.wolframalpha.com/'>Wolfram|Alpha</a>—where now we wanted a system that would just deal with whatever input someone might provide. At first it was jarring. How could we develop any kind of manageable system based on boatloads of potentially incompatible heuristics? It took a little while, but eventually we realized that when everything is a heuristic there’s a certain pattern and structure to that. And over time the development we do has become progressively more systematic.</p>\n<p>And so, I expect, it will be with prompts. In the Wolfram Prompt Repository today, we have a collection of prompts that cover a variety of areas, but are almost all “first level”, in the sense that they depend only on the base LLM, and not on other prompts. But over time I expect there’ll be whole hierarchies of prompts that develop (including metaprompts for building prompts, etc. ) And indeed I won’t be surprised if in this way all sorts of “repeatable lumps of functionality” are found, that actually can be implemented in a direct computational way, without depending on LLMs. (And, yes, this may well go through the kind of <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'>&#8220;semantic grammar&#8221; structure that I&#8217;ve discussed elsewhere</a>.)</p>\n<p>But as of now, we’re still just at the point of first launching the Wolfram Prompt Repository, and beginning the process of understanding the range of things—both useful and fun—that can be achieved with prompts. But it’s already clear that there’s going to be a very interesting world of prompts—and a progressive development of “prompt language” that in some ways will probably parallel (though at a considerably faster rate) the historical development of ordinary human languages. </p>\n<p>It’s going to be a community effort—just as it is with ordinary human languages—to explore and build out “prompt language”. And now that it’s launched, I’m excited to see how people will use our Prompt Repository, and just what remarkable things end up being possible through it.</p>\n",

To the Wolfram Language 2 + 3 is <tt><a href=\"http://reference.wolfram.com/language/ref/Plus.html\">Plus</a></tt><tt>[2,3]</tt>, where <tt><a href=\"http://reference.wolfram.com/language/ref/Plus.html\">Plus</a></tt> is just a symbolic object.

On its own, <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> is just a symbolic object (we’ll explain later why it’s displayed 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/sw052223activevoiceimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223activevoiceimg1.png' alt='' title='' width='378' height='84'> </div>\n</p></div>\n<p>But when we apply it to an argument, the LLM does its work, and we get 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/sw052223activevoiceimg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223activevoiceimg2.png' alt='' title='' width='647' height='81'> </div>\n</p></div>\n<p>If we want to, we can assign a name to 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/sw052223activevoiceimg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223activevoiceimg3.png' alt='' title='' width='459' height='51'> </div>\n</p></div>\n<p>and now we can use this name to refer to the function:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg10.png' alt='' title='' width='329' height='46'> </div>\n</p></div>\n<p>It’s all rather elegant and powerful—and connects quite seamlessly into the whole structure of the Wolfram Language.

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=''/></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=''/></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=''> </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=''> </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. But the basic idea is just that <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a> retrieves representations of prompts 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/sw052223Aimg70_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/w052223Aimg70B.png' alt='' title='' width='300' height=''> </div>\n</p></div>\n<p>An important kind of modifier prompts are ones intended to force the output from an <a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> to have a particular structure, that for example can readily be interpreted in computable Wolfram Language form. 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=''/></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=''/></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=''> </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=''> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg76B.png' alt='' title='' width='300' height=''></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.

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>.

The ultimate goal of <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a> is to retrieve pre-written prompts and then derive from them text that can be “spliced into” <a href=\"https://reference.wolfram.com/language/ref/LLMSynthesize.html\"><tt>LLMSynthesize</tt></a>. Sometimes prompts (say in the <a href=\"https://resources.wolframcloud.com/PromptRepository/\">Wolfram Prompt Repository</a>) could just be pure pieces of text. But sometimes they need parameters. 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>. And one way to extract that is just to apply <a href=\"https://reference.wolfram.com/language/ref/LLMPrompt.html\"><tt>LLMPrompt</tt></a> to <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/sw052223Aimg101_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg101B.png' alt='' title='' width='361' height=''> </div>\n</p></div>\n<p>It’s also possible to get this using <tt><a href=\"http://reference.wolfram.com/language/ref/Information.html\">Information</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg102_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg102C.png' alt='' title='' width='455' height=''> </div>\n</p></div>\n<p>When you include (possibly several) modifier prompts in <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. what you’re effectively doing is “composing” prompts. 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&#8217;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=''> expression into a string (in this case <tt><a href=\"https://reference.wolfram.com/language/ref/RGBColor.html\">RGBColor</a>[</tt>&#8230;<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>. For example, here’s an <tt><a href=\"http://reference.wolfram.com/language/ref/InsertionFunction.html\">InsertionFunction</a></tt> that “reads an image” by using <tt><a href=\"http://reference.wolfram.com/language/ref/ImageIdentify.html\">ImageIdentify</a></tt> to find what’s in it:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg105_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223Aimg105A.png' alt='' title='' width='576' height=''> </div>\n</p></div>\n<h2 id=\"what-about-the-llm-inside?\">What about the LLM Inside?</h2>\n<p><a href=\"https://reference.wolfram.com/language/ref/LLMFunction.html\"><tt>LLMFunction</tt></a> etc. “package up” LLM functionality so that it can be used as an integrated part of the Wolfram Language. 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.

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=''> </div>\n</p></div>\n<p>In this case, it goes on for a long time, but finally hits a stop token and stops.

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.

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 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.

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=''> </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=''> </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=''> </br> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw052223interrogation2A.png' alt='' title='' width='675' height=''></div>\n</p></div>\n<h2 id=\"this-is-just-the-beginning...\">This Is Just the Beginning&#8230;</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",

One can think of this as adding broad “computational superpowers” to ChatGPT, giving access to all the general computational capabilities and computational knowledge in Wolfram Language and Wolfram|Alpha. </p>\n<p>But what if you want to make your own special plugin, that does specific computations, or has access to data or services that are for example available only on your own computer or computer system? Well, today we’re releasing a <a href=\"https://resources.wolframcloud.com/PacletRepository/resources/Wolfram/ChatGPTPluginKit/\">first version of a kit for doing that</a>. And building on our whole Wolfram Language tech stack, we’ve managed to make the whole process extremely easy—to the point where it’s now realistic to deploy at least a basic custom ChatGPT plugin in under a minute.<span id=\"more-47759\"></span></p>\n<p>There’s some (very straightforward) one-time setup you need—authenticating with <a href=\"https://openai.com/\" target=\"_blank\" rel=\"noopener\">OpenAI</a>, and installing the Plugin Kit.

Let’s say you make up the idea of a “strength” for a word, defining it to be the sum of the “letter numbers” (“a” is 1, “b” is 2, etc.). In Wolfram Language you can compute this as:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Aimg1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Aimg1.png' alt='' title='' width='299' height='44'> </div>\n</p></div>\n<p>And for <a href=\"https://writings.stephenwolfram.com/2014/06/wolfram-programming-cloud-is-live/\">over a decade it&#8217;s been standard</a> that you can instantly <a href=\"https://reference.wolfram.com/language/workflow/DeployAWebAPI.html\">deploy such a computation as a web API</a> in the <a href=\"https://www.wolframcloud.com/\">Wolfram Cloud</a>—immediately accessible through a web browser, <a href=\"https://reference.wolfram.com/language/WolframClientForPython/\">external program</a>, etc.:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg2.png' alt='' title='' width='991' height='68'> </div>\n</p></div>\n<p>But today there’s a new form of deployment: as a plugin for ChatGPT. First, you say you need the Plugin Kit:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg3_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg3.png' alt='' title='' width='310' height='14'> </div>\n</p></div>\n<p>Then you can immediately deploy your plugin. All it takes is:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Aimg4_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Aimg4.png' alt='' title='' width='670' height='130'> </div>\n</p></div>\n<p>The final step is that you have to tell ChatGPT about your plugin. Within the web interface (as it’s currently configured), select <span class=\"computer-voice\">Plugins > Plugin store > Develop your own plugin</span> and insert the URL from the <tt>ChatGPTPluginDeployment</tt> (which you get by pressing the click-to-copy button <img style=\"margin-bottom: -8px\" src='https://content.wolfram.com/sites/43/2023/04/sw042723Aimg5.png' alt='' title='' width='23' height='24'/>) into the dialog you get:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg6.png' alt='ChatGPT plugin dialog' title='ChatGPT plugin dialog' width='620' height='186'/></p>\n<p>Now everything’s ready. And you can start talking to ChatGPT about “word strengths”, and it’ll call your plugin (which by default is called “WolframCustom”) to compute them:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img9_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg7.png' alt='' title='' width='937' height=''> </div>\n</p></div>\n<p>Looking “inside the box” shows the communication ChatGPT had with the plugin:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img10_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg8.png' alt='' title='' width='933' height='502'> </div>\n</p></div>\n<p>Without the plugin it won’t know what “letter strength” is. But with the plugin, it’ll be able to do all kinds of (rather remarkable) things with it—like this:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg9.png' alt='' title='' width='933' height='553'> </div>\n</p></div>\n<p>The embellishment about properties of gnus is charming, but if one opens the boxes one can see how it got its answer—it just started trying different animals (“lion”, “zebra”, “gnu”):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img12_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg10.png' alt='' title='' width='933' height='852'> </div>\n</p></div>\n<p>Software engineers will immediately notice that the plugin we’ve set up is running against localhost, i.e. it’s executing on your own computer. As we’ll discuss, this is often an incredibly useful thing to be able to do. But you can also use the Plugin Kit to create plugins that execute purely in the <a href=\"https://www.wolframcloud.com/\">Wolfram Cloud</a> (so that, for example, you don’t have to have a <a href=\"https://www.wolfram.com/engine/\">Wolfram Engine</a> available on your computer).</p>\n<p>All you do is use <tt>ChatGPTPluginCloudDeploy</tt>—then you get a URL in the Wolfram Cloud that you can tell ChatGPT as the location of your plugin:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg11_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg11A-1.png' alt='' title='' width='572' height=''> </div>\n</p></div>\n<p>And in fact you can do the whole setup directly in your web browser, without any local Wolfram installation. You just open a notebook in the Wolfram Cloud, and deploy your plugin from there: </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg12.png' alt='Wolfram Cloud notebook' title='Wolfram Cloud notebook' width='488' height=''/></p>\n<p>Let’s do some other examples. For our next example, let’s invent the concept of a “geo influence disk” and then deploy a plugin that renders such a thing (we’ll talk later about some details of what’s being done here):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg13_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg13.png' alt='' title='' width='631' height='134'> </div>\n</p></div>\n<p>Now we can install this new plugin—and then start asking ChatGPT about “geo influence disks”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg15.png' alt='' title='' width='933' height='1017'> </div>\n</p></div>\n<p>ChatGPT successfully calls the plugin, and brings back an image. Somewhat amusingly, it guesses (correctly, as it happens) what a “geo influence disk” is supposed to be. And remember, it can’t see the picture or read the code, so its guess has to be based only on the name of the API function and the question one asks. Of course, it has to effectively understand at least a bit in order to work out how to call the API function—and that <tt>x</tt> is supposed to be a location, and <tt>radius</tt> a distance. </p>\n<p>As another example, let’s make a plugin that sends the user (i.e. the person who deploys the plugin) a text message:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg16_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg16.png' alt='' title='' width='413' height='86'> </div>\n</p></div>\n<p>Now just say “send me a message”</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img18_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg17.png' alt='' title='' width='933' height='231'> </div>\n</p></div>\n<p>and a text message will arrive—in this case with a little embellishment from ChatGPT:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg18A.png' alt='Rhinoceros alert' title='Rhinoceros alert' width='330' height=''/></p>\n<p>Here’s a plugin that also sends an “alert picture” of an animal that’s mentioned:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg19_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg19.png' alt='' title='' width='642' height='189'> </div>\n</p></div>\n<p>And, yes, there’s a lot of technology that needs to work to get this to happen:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img21_copy.txt' data-c2c-type='text/html'> <img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg21.png' alt='' title='' width='622' height='277'/></div>\n</p></div>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg22.png' alt='Gnu alert' title='Gnu alert' width='295' height='183'/></p>\n<p>As another example, let’s make a plugin that retrieves <a href=\"https://writings.stephenwolfram.com/2012/03/the-personal-analytics-of-my-life/\">personal data of mine</a>—here heart rate data that I’ve been accumulating for several years in a <a href=\"https://datadrop.wolframcloud.com/\">Wolfram databin</a>: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg23_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg23.png' alt='' title='' width='556' height='86'> </div>\n</p></div>\n<p>Now we can use ChatGPT to ask questions about this data:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img24_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg24.png' alt='' title='' width='933' height='276'> </div>\n</p></div>\n<p>And with the <a href=\"https://writings.stephenwolfram.com/2023/03/chatgpt-gets-its-wolfram-superpowers/\">main Wolfram plugin</a> also installed, we can immediately do actual computations on this data, all through ChatGPT’s “<a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/\">linguistic user interface</a>”:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img25_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg25.png' alt='' title='' width='933' height='814'> </div>\n</p></div>\n<p>This example uses the <a href=\"https://datadrop.wolframcloud.com/\">Wolfram Data Drop</a> system.

But with plugins you can “reach back”—through your web browser—to make things happen on your own, local computer. We’ll talk later about how this works “under the hood”, but suffice it to say now that when you deploy a plugin using <tt>ChatGPTPluginDeploy</tt> (as opposed to <tt>ChatGPTPluginCloudDeploy</tt>) the actual Wolfram Language code in the plugin will be run on your local computer. So that means it can get access to local resources on your computer, like your camera, speakers, files, etc.</p>\n<p>For example, here I’m setting up a plugin to take a picture with my computer’s camera (using the Wolfram Language <tt><a href=\"http://reference.wolfram.com/language/ref/CurrentImage.html\">CurrentImage</a></tt><tt style=\"font-weight: 600;\">[ ]</tt>)—and then blend the picture with whatever color I specify (we’ll talk about the use of <tt><a href=\"http://reference.wolfram.com/language/ref/CloudExport.html\">CloudExport</a></tt> later):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg26_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg26.png' alt='' title='' width='1006' height='297'> </div>\n</p></div>\n<p>Installing the plugin, I then say to ChatGPT “Just picture me in green!”, and, right then and there, ChatGPT will call the plugin, which gets my computer to take a picture of me—and then blends it with green (complete with my “I wonder if this is going to work” look):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img27_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg27.png' alt='' title='' width='933' height='555'> </div>\n</p></div>\n<p>OK let’s try a slightly more sophisticated example.

We are all, by any practical definition of the words, foolproof and incapable of error.”</p></blockquote>\n<h2 id=\"how-it-all-works-\">How It All Works </h2>\n<p>We’ve now seen lots of examples of using the <a href=\"https://resources.wolframcloud.com/PacletRepository/resources/Wolfram/ChatGPTPluginKit/\">ChatGPT Plugin Kit</a>. But how do they work? What’s under the hood? When you run <tt>ChatGPTPluginDeploy</tt> you’re basically setting up a Wolfram Language function that can be called from inside ChatGPT when ChatGPT decides it’s needed. And to make this work smoothly turns out to be something that uses a remarkable spectrum of unique capabilities of Wolfram Language—dovetailed with certain “cleverness” in ChatGPT.</p>\n<p>From a software engineering point of view, a ChatGPT plugin is fundamentally one or more web APIs—together with a “manifest” that tells ChatGPT how to call these APIs. So how does one set up a web API in Wolfram Language? Well, a <a href=\"https://writings.stephenwolfram.com/2014/06/wolfram-programming-cloud-is-live/\">decade ago we invented</a> a way to make it extremely easy.</p>\n<p>Like everything in Wolfram Language, a web API is represented by a <a href=\"https://www.wolfram.com/language/fast-introduction-for-programmers/en/symbolic-expressions/\">symbolic expression</a>, in this case of the form <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt><tt>[…]</tt>. What’s inside the <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt>? There are two pieces. A piece of Wolfram Language code that implements the function one wants, together with a specification for how the strings that will actually be passed to the <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt> (say from a web API) should be interpreted before feeding them to the Wolfram Language code.</p>\n<p>Here’s a little piece of Wolfram Language code, in this case for <a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/07-colors-and-styles.html\">negating a color</a>, then making it lighter:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg57_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg57A.png' alt='' title='' width='278' height=''> </div>\n</p></div>\n<p>If we wanted to, we could refactor this as a “<a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/26-pure-anonymous-functions.html\">pure function</a>” applied to two arguments:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg58_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg58A.png' alt='' title='' width='359' height=''> </div>\n</p></div>\n<p>On its own the pure function is just a symbolic expression that evaluates to itself:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg59_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg59A.png' alt='' title='' width='278' height=''> </div>\n</p></div>\n<p>If we want to, we can name the arguments of the pure function, then supply them in an <a href=\"https://www.wolfram.com/language/elementary-introduction/3rd-ed/34-associations.html\">association</a> (<span class='InlineFormula'><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg60.png' width= '53' height='13' align='absmiddle'></span>) with their names as keys:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg61_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg61A.png' alt='' title='' width='577' height=''> </div>\n</p></div>\n<p>But let’s say we want to call our function from a web API. The parameters in the web API are always strings. So how can we convert from a string (like <tt>\"lime green\"</tt>) to a symbolic expression that Wolfram Language can understand? Well, we have to use the <a href=\"https://www.wolfram.com/natural-language-understanding/\">natural language understanding</a> capabilities of Wolfram Language.</p>\n<p>Here’s an example, where we’re saying we want to <a href=\"https://reference.wolfram.com/language/ref/Interpreter.html\">interpret</a> a string as a color:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg62_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg62A.png' alt='' title='' width='294' height=''> </div>\n</p></div>\n<p>What really is that color swatch?

The first argument says the API we’re representing has two parameters, and describes how we want to interpret these. The second argument gives the actual Wolfram Language function that the API computes. On its own, the <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt> is just a symbolic expression that evaluates to itself:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg64_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg64A.png' alt='' title='' width='609' height=''> </div>\n</p></div>\n<p>But if we supply values for the parameters (here using an association) it’ll evaluate:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg65_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg65.png' alt='' title='' width='979' height='102'> </div>\n</p></div>\n<p>So far all this is just happening inside our Wolfram Language session. But to get an actual web API we just have to “cloud deploy” our <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg66_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg66.png' alt='' title='' width='991' height='104'> </div>\n</p></div>\n<p>Now we can call this web API, say from a web browser:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg67.png' alt='Web API' title='Web API' width='620' height='196'/></p>\n<p>And, yes, that’s the symbolic expression result. If we’d wanted something visual, we could tell the <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt> to give its results, say as a <a href=\"https://reference.wolfram.com/language/ref/format/PNG.html\">PNG</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg68_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg68.png' alt='' title='' width='518' height='38'> </div>\n</p></div>\n<p>And now it’ll show up as an image in a web browser:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg69.png' alt='Purple box in web browser' title='Purple box in web browser' width='620' height='196'/></p>\n<p>(Note that <tt><a href=\"http://reference.wolfram.com/language/ref/CloudDeploy.html\">CloudDeploy</a></tt> deploys a web API that by default has permissions set so that only I can run it. If you use <tt><a href=\"http://reference.wolfram.com/language/ref/CloudPublish.html\">CloudPublish</a></tt> instead, anyone will be able to run it.)</p>\n<p>OK, so how do we set up our web API so it can be called as a ChatGPT plugin? One immediate issue is that at the simplest level ChatGPT just deals with text, so we’ve somehow got to convert our result to text. So let’s do a little Wolfram Language programming to achieve that. Here’s a list of values and names of common colors from the <a href=\"https://www.wolfram.com/knowledgebase/\">Wolfram Knowledgebase</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg70_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw050923img1.png' alt='' title='' width='621' height=''> </div>\n</p></div>\n<p>Of course, we know about many other collections of named colors too, but let’s not worry about that here:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg71_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw050923img2D.png' alt='' title='' width='705' height=''> </div>\n</p></div>\n<p>Now we can use <tt><a href=\"http://reference.wolfram.com/language/ref/Nearest.html\">Nearest</a></tt> to find which common color is nearest to the color we’ve got:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg72_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg72.png' alt='' title='' width='606' height=''> </div>\n</p></div>\n<p>Now let’s put this into an <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt> (we’ve “<a href=\"https://reference.wolfram.com/language/ref/Iconize.html\">iconized</a>” the list of colors here; we could also have defined a separate function for finding nearest colors, which would automatically be brought along by <tt><a href=\"http://reference.wolfram.com/language/ref/CloudDeploy.html\">CloudDeploy</a></tt>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg73_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw050923Aimg1.png' alt='' title='' width='594' height=''> </div>\n</p></div>\n<p>Now we’re ready to use <tt>ChatGPTPluginDeploy</tt>. The way ChatGPT plugins work, we’ve got to give a name to the “endpoint” corresponding to our API. And this name—along with the names we used for the parameters in our API—will be used by ChatGPT to figure out when and how to call our plugin. But in this example, we just want to use some kind of unique name for the endpoint, so we’ll be able to refer to it in our chat without ChatGPT confusing it with something else. So let’s call it <tt>ColorMangle</tt>. So now let’s do the deployment:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg74_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw050923Aimg2.png' alt='' title='' width='599' height='256'> </div>\n</p></div>\n<p>Everything we’ve said so far about <tt><a href=\"http://reference.wolfram.com/language/ref/APIFunction.html\">APIFunction</a></tt> and how it’s called works the same in <tt>ChatGPTPluginDeploy</tt> and <tt>ChatGPTPluginCloudDeploy</tt>. But what we’ll say next is different. Because <tt>ChatGPTPluginDeploy</tt> sets up the API function to execute on your local computer, while <tt>ChatGPTPluginCloudDeploy</tt> sets it up to run in the <a href=\"https://www.wolframcloud.com/\">Wolfram Cloud</a> (or it could be a <a href=\"https://www.wolfram.com/enterprise-private-cloud/\">Wolfram Enterprise Private Cloud</a>, etc.). </p>\n<p>There are advantages and disadvantages to both local and cloud deployment. Running locally allows you to get access to local features of your computer, like camera, filesystem, etc. Running in the cloud allows you to let other people also run your plugin (though, currently, unless you <a href=\"https://platform.openai.com/docs/plugins/review\" target=\"_blank\" rel=\"noopener\">register your plugin with OpenAI</a>, only a limited number of people will be able to install your plugin at any one time).</p>\n<p>But, OK, let’s talk about local plugin deployment. <tt>ChatGPTPluginDeploy</tt> effectively sets up a <a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/WebServerDeploy/\">minimal web server on your computer</a> (implemented with <a href=\"https://resources.wolframcloud.com/FunctionRepository/resources/WebServerDeploy/\">10 lines of Wolfram Language code</a>), running on a port that <tt>ChatGPTPluginDeploy</tt> chooses, and calling the Wolfram Engine with your API function whenever it receives a request to the API’s URL.</p>\n<p>Here’s the operating system socket that <tt>ChatGPTPluginDeploy</tt> is using (and, yes, the Wolfram Language represents sockets—like everything else—as symbolic expressions):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg75_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/05/sw050923Bimg1.png' alt='' title='' width='659' height=''> </div>\n</p></div>\n<p>OK, but how does ChatGPT know about your API? First, you have to tell it the port you’re using, which you do through the ChatGPT UI (<span class=\"computer-voice\">Plugins > Plugin store > Develop your own plugin</span>). You can find the port by clicking the <img style=\"margin-bottom: -8px\" src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg76.png' alt='' title='' width='23' height='24'/> icon in the <tt>ChatGPTPluginDeployment</tt> object, or programmatically with:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg77_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg77A.png' alt='' title='' width='488' height=''> </div>\n</p></div>\n<p>You enter this URL, then tell ChatGPT to “Find manifest file”: </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg78.png' alt='Find manifest file' title='Find manifest file' width='620' height='186'/></p>\n<p>Let’s look at what it found:</p>\n<p> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg79.png' alt='' title='' width='365' height=''></p>\n<p>It’s a “manifest” that tells it about the plugin you’re installing. We didn’t specify much, so most things here are just defaults. But an important piece of the manifest is the part that gives the URL for API spec: <span class=\"computer-voice\">http://localhost:59353/.well-known/openapi.json</span> </p>\n<p>And going there we find this “OpenAPI spec”: </p>\n<p><img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg80.png' alt='Validated OpenAPI spec' title='Validated OpenAPI spec' width='200' height=''> </p>\n<p>Finally, click <span style=\"color:#000000;font-size:13px;font-family:AppleSystemUIFont\"><span class=\"kbd\"><kbd>Install localhost plugin</kbd></kbd></span></span>, and the plugin will show up in the list of installed plugins in your ChatGPT session:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg81_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg81.png' alt='' title='' width='450' height=''> </div>\n</p></div>\n<p>And when ChatGPT starts with the plugin installed, it includes an extra piece in its “system prompt”, that lets it “learn” how to call the plugin: </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg82C.png' alt='System prompt' title='System prompt' width='260' height=''/></p>\n<p>So now we’re ready to use the plugin:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img83_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg83.png' alt='' title='' width='933' height='310'> </div>\n</p></div>\n<p>And, yes, it works. But there’s a bit of magic here. Somehow ChatGPT had to “take apart” what we’d asked, realize that the API endpoint called <tt>ColorMangle</tt> was relevant, then figure out that its color parameter should be “lime green”, and its level should be “0.5”. Opening the box, we can see what it did:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img84_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg84.png' alt='' title='' width='933' height='609'> </div>\n</p></div>\n<p>And now we can start using “color mangling” in other places—though ChatGPT hastens to tell us that “color mangling” is a “fictional operation”, perhaps lest it’s accused of disrespecting a country’s flag colors:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img85_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg85.png' alt='' title='' width='933' height='603'> </div>\n</p></div>\n<p>In the case we’re dealing with here, ChatGPT manages to correctly “wire up” fragments of text to appropriate parameters in our API. And it does that (rather remarkably) just from the scrap of information it gleans from the names we used for the parameters (and the name we gave the endpoint). </p>\n<p>But sometimes we have to tell it a bit more, and we can do that by specifying a prompt for the plugin inside <tt>ChatGPTPluginDeploy</tt>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg86_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg86.png' alt='' title='' width='595' height='176'> </div>\n</p></div>\n<p>Now we don’t have to just talk about colors:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042823img87_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg87.png' alt='' title='' width='933' height='1075'> </div>\n</p></div>\n<p>At first, it didn’t successfully “untangle” the “colors of Iceland”, but then it corrected itself, and got the answers. (And, yes, we might have been able to avoid this by writing a better prompt.)</p>\n<p>And actually, there are multiple levels of prompts you can give. You can include a fairly long prompt for the whole plugin. Then you can give shorter prompts for each individual API endpoint. And finally, you can give prompts to help ChatGPT interpret individual parameters in the API, for example by replacing <tt>\"color\" </tt><tt><a href=\"https://reference.wolfram.com/language/ref/Rule.html\">&rarr;</a></tt><tt> \"Color\"</tt> with something like:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg88_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw042723Ximg88.png' alt='' title='' width='513' height='14'> </div>\n</p></div>\n<p>When you set up a plugin, it can contain many endpoints, that do different things. And—in addition to sharing prompts—one reason this is particularly convenient is that (at least right now, for security reasons) any given subdomain can have only one associated plugin. So if one wants to have a range of functionality, this has to be implemented by having different endpoints.</p>\n<p>For <tt>ChatGPTPluginCloudDeploy</tt> the one-plugin-per-subdomain limit currently means that any given user can only deploy one cloud plugin at a time. But for local plugins the rules are a bit different, and <tt>ChatGPTPluginDeploy</tt> can deploy multiple plugins by just having them run on different ports—and indeed by default <tt>ChatGPTPluginDeploy</tt> just <a href=\"https://reference.wolfram.com/language/ref/SocketOpen.html\">picks a random unused port</a> every time you call it.</p>\n<p>But how does a local plugin really work? And how does it “reach back” to your computer? The magic is basically happening in the ChatGPT web front end. The way all plugins work is that when the plugin is going to be called, the <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">token-at-a-time generation process</a> of the LLM stops, and the next action of the “outer loop” is to call the plugin—then add whatever result it gives to the string that will be fed to the LLM at the next step. Well, in the case of a local plugin, the outer loop uses JavaScript in the ChatGPT front end to send a request locally on your computer to the localhost port you specified. (By the way, once <tt>ChatGPTPluginDeploy</tt> opens a port, it’ll stay open until you explicitly call <tt><a href=\"http://reference.wolfram.com/language/ref/Close.html\">Close</a></tt> on its <a href=\"https://reference.wolfram.com/language/ref/SocketObject.html\">socket object</a>.)</p>\n<p>When one’s using local plugins, they’re running their Wolfram Language code right in the Wolfram Language session from which the plugin was deployed. And this means, for example, that (as we saw in some cases above) values that get set in one plugin call are still there when another call is made. </p>\n<p>In the cloud it doesn’t immediately work this way, because each API call is effectively independent. But it’s straightforward to save state in cloud objects (say using <tt><a href=\"http://reference.wolfram.com/language/ref/CloudPut.html\">CloudPut</a></tt>, or with <tt><a href=\"http://reference.wolfram.com/language/ref/CloudExpression.html\">CloudExpression</a></tt>, etc.) so that one can have “persistent memory” across many API calls.</p>\n<p>The LLM inside ChatGPT is (currently) set up to deal only with text. So what happens with images? Well, plugins can put them into the Wolfram Cloud, then pass their URLs to ChatGPT. And ChatGPT is set up to be able to render directly certain special kinds of things—like images. </p>\n<p>So—as we saw above—to “output” an image (or several) from a plugin, we can use <tt><a href=\"http://reference.wolfram.com/language/ref/CloudExport.html\">CloudExport</a></tt> to put each image in a cloud object, say in PNG format. And then ChatGPT, perhaps with some prompting, can show the image inline in its output.</p>\n<p>There’s some slightly tricky “plumbing” in deploying Wolfram Language plugins in ChatGPT, most of which is handled automatically in <tt>ChatGPTPluginDeploy</tt> and <tt>ChatGPTPluginCloudDeploy</tt>. But by building on the fundamental symbolic structure of the Wolfram Language (and its integrated deployment capabilities) it’s remarkably straightforward to create elaborate custom Wolfram Language plugins for ChatGPT, and to contribute to the emerging ecosystem around LLMs and Wolfram Language.</p>\n",

And today—just two and a half months later—I’m excited to announce that <a href=\"https://openai.com/blog/chatgpt-plugins\" target=\"_blank\">it’s happened</a>! Thanks to some heroic software engineering by <a href=\"https://www.wolfram.com/\">our team</a> and by <a href=\"https://openai.com/\" target=\"_blank\" rel=\"noopener\">OpenAI</a>, ChatGPT can now call on Wolfram|Alpha—and <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> as well—to give it what we might think of as “computational superpowers”. It’s still very early days for all of this, but it’s already very impressive—and one can begin to see how amazingly powerful (and perhaps even revolutionary) what we can call “<nobr>ChatGPT + Wolfram</nobr>” can be.</p>\n<p>Back in January, I made the point that, as an <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">LLM neural net</a>, ChatGPT—for all its remarkable prowess in textually generating material “like” what it’s read from the web, etc.—<a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">can’t itself be expected to do actual nontrivial computations</a>, or to systematically produce correct (rather than just “looks roughly right”) data, etc. But when it’s connected to the Wolfram plugin it can do these things. So here’s my (very simple) first example from January, but now done by ChatGPT with “Wolfram superpowers” installed:<span id=\"more-46756\"></span></p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img2.png' alt='How far is it from Tokyo to Chicago?' title='How far is it from Tokyo to Chicago?' width='622' height='232'/></p>\n<p>It’s a correct result (which in January it wasn’t)—found by actual computation. And here’s a bonus: immediate visualization:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img3.png' alt='Show the path' title='Show the path' width='622' height='388'/></p>\n<p>How did this work? Under the hood, ChatGPT is formulating a query for Wolfram|Alpha—then <a href=\"https://www.wolfram.com/resources/tools-for-AIs/\">sending it to Wolfram|Alpha for computation</a>, and then “deciding what to say” based on reading the results it got back. You can see this back and forth by clicking the “Used Wolfram” box (and by looking at this you can check that ChatGPT didn’t “make anything up”):</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img4A.png' alt='Used Wolfram' title='Used Wolfram' width='621' height='444'/></p>\n<p>There are lots of nontrivial things going on here, on both the ChatGPT and Wolfram|Alpha sides. But the upshot is a good, correct result, knitted into a nice, flowing piece of text. </p>\n<p>Let’s try another example, also from what I wrote in January: </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img5.png' alt='What is the integral?' title='What is the integral?' width='622' height='539/2'/></p>\n<p>A fine result, <a href=\"https://www.wolframalpha.com/input?i=What+is+the+integral+of+x%5E2+cos%282x%29\">worthy of our technology</a>. And again, we can get a bonus:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img6.png' alt='Plot that' title='Plot that' width='622' height='494'/></p>\n<p>In January, I noted that ChatGPT ended up just “making up” plausible (but wrong) data when given this prompt:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img7.png' alt='Tell me about livestock populations' title='Tell me about livestock populations' width='622' height='633/2'/></p>\n<p>But now it calls the Wolfram plugin and gets a <a href=\"https://reference.wolfram.com/language/ref/entity/Country.html\">good, authoritative answer</a>. And, as a bonus, we can also make a visualization:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img8A.png' alt='Make a bar chart' title='Make a bar chart' width='622' height=''/></p>\n<p>Another example from back in January that now comes out correctly is: </p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img9.png' alt='What planetary moons are larger than Mercury?' title='What planetary moons are larger than Mercury?' width='621' height='675/2'/></p>\n<p>If you actually try these examples, don’t be surprised if they work differently (sometimes better, sometimes worse) from what I’m showing here. Since <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">ChatGPT uses randomness</a> in generating its responses, different things can happen even when you ask it the exact same question (even in a fresh session). It feels “very human”. But different from the solid “right-answer-and-it-doesn’t-change-if-you-ask-it-again” experience that one gets in Wolfram|Alpha and Wolfram Language.</p>\n<p>Here’s an example where we saw ChatGPT (rather impressively) “having a conversation” with the Wolfram plugin, after at first finding out that it got the “wrong Mercury”:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img10.png' alt='How big is Mercury?' title='How big is Mercury?' width='622' height='482'/></p>\n<p>One particularly significant thing here is that ChatGPT isn’t just using us to do a “dead-end” operation like show the content of a webpage. Rather, we’re acting much more like a true “brain implant” for ChatGPT—where it asks us things whenever it needs to, and we give responses that it can weave back into whatever it’s doing. It’s rather impressive to see in action. And—although there’s definitely much more polishing to be done—what’s already there goes a long way towards (among other things) giving ChatGPT the ability to deliver accurate, curated knowledge and data—as well as correct, nontrivial computations.</p>\n<p>But there’s more too. We already saw examples where we were able to provide custom-created visualizations to ChatGPT. And with our computation capabilities we’re routinely able to make “truly original” content—computations that have simply never been done before.

But what can one do when that conversation has actual computation and computational knowledge in it? Here’s an example. Start by asking a “world knowledge” question:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img16.png' alt='Beef production query' title='Beef production query' width='622' height='432'/></p>\n<p>And, yes, by “opening the box” one can check that the right question was asked to us, and what the raw response we gave was. But now we can go on and ask for a map:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img17.png' alt='Make a map' title='Make a map' width='622' height='444'/></p>\n<p>But there are “prettier” map projections we could have used. And with ChatGPT’s “general knowledge” based on its reading of the web, etc. we can just ask it to use one:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img18.png' alt='Use a prettier map projection' title='Use a prettier map projection' width='622' height='448'/></p>\n<p>But maybe we want a heat map instead. Again, we can just ask it to produce this—underneath using our technology:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img19.png' alt='Show as a heat map' title='Show as a heat map' width='622' height='478'/></p>\n<p>Let’s change the projection again, now asking it again to pick it using its “general knowledge”:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img20.png' alt='Use UN logo map projection' title='Use UN logo map projection' width='622' height='1231/2'/></p>\n<p>And, yes, it got the projection “right”. But not the centering. So let’s ask it to fix that:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img21.png' alt='Center map projection on North Pole' title='Center map projection on North Pole' width='622' height='592'/></p>\n<p>OK, so what do we have here? We’ve got something that we “collaborated” to build. We incrementally said what we wanted; the AI (i.e. <nobr>ChatGPT + Wolfram</nobr>) progressively built it. But what did we actually get? Well, it’s a piece of Wolfram Language code—which we could see by “opening the box”, or just asking ChatGPT for:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img22.png' alt='Show the code used' title='Show the code used' width='622' height='426'/></p>\n<p>If we copy the code out into a <a href=\"https://www.wolfram.com/notebooks/\">Wolfram Notebook</a>, we can immediately run it, and we find it has a nice “luxury feature”—as ChatGPT claimed in its description, there are dynamic tooltips giving the name of each country:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw032223img23A_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw032223img23-v2.png' alt='' title='' width='611' height=''> </div>\n</p></div>\n<p>(And, yes, it’s a slight pity that this code just has explicit numbers in it, rather than the original symbolic query about beef production. And this happened because ChatGPT asked the original question to Wolfram|Alpha, then fed the results to Wolfram Language. But I consider the fact that this whole sequence works at all extremely impressive.)</p>\n<h2 id=\"how-it-works—and-wrangling-the-ai\">How It Works—and Wrangling the AI</h2>\n<p>What’s happening “under the hood” with ChatGPT and the Wolfram plugin? Remember that the <a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">core of ChatGPT is a “large language model” (LLM)</a> that’s trained from the web, etc. to generate a “reasonable continuation” from any text it’s given. But as a final part of its training ChatGPT is also taught how to “hold conversations”, and when to “ask something to someone else”—where that “someone” might be a human, or, for that matter, a plugin. And in particular, it’s been taught when to reach out to the Wolfram plugin.</p>\n<p>The Wolfram plugin actually has two entry points: a Wolfram|Alpha one and a Wolfram Language one. The Wolfram|Alpha one is in a sense the “easier” for ChatGPT to deal with; the Wolfram Language one is ultimately the more powerful. The reason the Wolfram|Alpha one is easier is that what it takes as input is just natural language—which is exactly what ChatGPT routinely deals with. And, more than that, Wolfram|Alpha is built to be forgiving—and in effect to <a href=\"https://www.wolfram.com/natural-language-understanding/\">deal with “typical human-like input”</a>, more or less however messy that may be.</p>\n<p>Wolfram Language, on the other hand, is set up to be precise and well defined—and capable of being used to build arbitrarily sophisticated towers of computation. Inside Wolfram|Alpha, what it’s doing is to translate natural language to precise Wolfram Language. In effect it’s catching the “imprecise natural language” and “funneling it” into precise Wolfram Language. </p>\n<p>When ChatGPT calls the Wolfram plugin it often just feeds natural language to Wolfram|Alpha. But ChatGPT has by this point learned a certain amount about writing Wolfram Language itself. And in the end, as we’ll discuss later, that’s a more flexible and powerful way to communicate. But it doesn’t work unless the Wolfram Language code is exactly right. To get it to that point is partly a matter of training. But there’s another thing too: given some candidate code, the Wolfram plugin can run it, and if the results are obviously wrong (like they generate lots of errors), ChatGPT can attempt to fix it, and try running it again. (More elaborately, ChatGPT can try to generate tests to run, and change the code if they fail.)</p>\n<p>There’s more to be developed here, but already one sometimes sees ChatGPT go back and forth multiple times. It might be rewriting its Wolfram|Alpha query (say simplifying it by taking out irrelevant parts), or it might be deciding to switch between Wolfram|Alpha and Wolfram Language, or it might be rewriting its Wolfram Language code. Telling it how to do these things is a matter for the initial “plugin prompt”. </p>\n<p>And writing this prompt is a strange activity—perhaps our first serious experience of trying to “<a href=\"https://writings.stephenwolfram.com/category/language-and-communication/\">communicate with an alien intelligence</a>”. Of course it helps that the “alien intelligence” has been trained with a vast corpus of human-written text. So, for example, it knows English (a bit like all those corny science fiction aliens&#8230;). And we can tell it things like “If the user input is in a language other than English, translate to English and send an appropriate query to Wolfram|Alpha, then provide your response in the language of the original input.” </p>\n<p>Sometimes we’ve found we have to be quite insistent (note the all caps): “When writing Wolfram Language code, NEVER use snake case for variable names; ALWAYS use camel case for variable names.” And even with that insistence, ChatGPT will still sometimes do the wrong thing. The whole process of “prompt engineering” feels a bit like animal wrangling: you’re trying to get ChatGPT to do what you want, but it’s hard to know just what it will take to achieve that. </p>\n<p>Eventually this will presumably be handled in training or in the prompt, but as of right now, ChatGPT sometimes doesn’t know when the Wolfram plugin can help. For example, ChatGPT guesses that this is supposed to be a DNA sequence, but (at least in this session) doesn’t immediately think the Wolfram plugin can do anything with it:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img24.png' alt='DNA strand input' title='DNA strand input' width='622' height='286'/></p>\n<p>Say “Use Wolfram”, though, and it’ll send it to the Wolfram plugin, which indeed handles it nicely:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img025A.png' alt='Use Wolfram' title='Use Wolfram' width='622' height=''/></p>\n<p>(You may sometimes also want to say specifically “Use Wolfram|Alpha” or “Use Wolfram Language”. And particularly in the Wolfram Language case, you may want to look at the actual code it sent, and tell it things like not to use functions whose names it came up with, but which don’t actually exist.)</p>\n<p>When the Wolfram plugin is given Wolfram Language code, what it does is basically just to evaluate that code, and return the result—perhaps as a graphic or math formula, or just text. But when it’s given Wolfram|Alpha input, this is sent to a special <a href=\"https://www.wolfram.com/resources/tools-for-AIs/\">Wolfram|Alpha “for LLMs” API</a> endpoint, and the result comes back as text intended to be “read” by ChatGPT, and effectively used as an additional prompt for further text ChatGPT is writing. Take a look at this example:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img26.png' alt='Ocean depth query' title='Ocean depth query' width='622' height='230'/></p>\n<p>The result is a nice piece of text containing the answer to the question asked, along with some other information ChatGPT decided to include. But “inside” we can see what the Wolfram plugin (and the Wolfram|Alpha “LLM endpoint”) actually did:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img027A.png' alt='Ocean depth code' title='Ocean depth code' width='622' height='738'/></p>\n<p>There’s quite a bit of additional information there (including some nice pictures!). But ChatGPT “decided” just to pick out a few pieces to include in its response.</p>\n<p>By the way, something to emphasize is that if you want to be sure you’re getting what you think you’re getting, always check what ChatGPT actually sent to the Wolfram plugin—and what the plugin returned. One of the important things we’re adding with the Wolfram plugin is a way to “factify” ChatGPT output—and to know when ChatGPT is “using its imagination”, and when it’s delivering solid facts. </p>\n<p>Sometimes in trying to understand what’s going on it’ll also be useful just to take what the Wolfram plugin was sent, and enter it as direct input on the Wolfram|Alpha website, or in a Wolfram Language system (such as the <a href=\"https://www.wolframcloud.com/\">Wolfram Cloud</a>).</p>\n<h2 id=\"wolfram-language-as-the-language-for-human-ai-collaboration\">Wolfram Language as the Language for Human-AI Collaboration</h2>\n<p>One of the great (and, frankly, unexpected) things about ChatGPT is its ability to start from a rough description, and generate from it a polished, finished output—such as an essay, letter, legal document, etc. In the past, one might have tried to achieve this “by hand” by starting with “boilerplate” pieces, then modifying them, “gluing” them together, etc. But ChatGPT has <a href=\"https://writings.stephenwolfram.com/2023/03/will-ais-take-all-our-jobs-and-end-human-history-or-not-well-its-complicated/\">all but made this process obsolete</a>. In effect, it’s “absorbed” a huge range of boilerplate from what it’s “read” on the web, etc.—and now it typically does a good job at seamlessly “adapting it” to what you need.</p>\n<p>So what about code? In traditional programming languages writing code tends to involve a lot of “boilerplate work”—and in practice many programmers in such languages spend lots of their time building up their programs by copying big slabs of code from the web. But now, suddenly, it seems as if ChatGPT can make much of this obsolete. Because it can effectively put together essentially any kind of boilerplate code automatically—with only a little “human input”. </p>\n<p>Of course, there has to be some human input—because otherwise ChatGPT wouldn’t know what program it was supposed to write. But—one might wonder—why does there have to be “boilerplate” in code at all? Shouldn’t one be able to have a language where—just at the level of the language itself—all that’s needed is a small amount of human input, without any of the “boilerplate dressing”?</p>\n<p>Well, here’s the issue. Traditional programming languages are centered around telling a computer what to do in the computer’s terms: set this variable, test that condition, etc. But it doesn’t have to be that way. And instead one can start from the other end: take things people naturally think in terms of, then try to represent these computationally—and effectively automate the process of getting them actually implemented on a computer.</p>\n<p>Well, this is what I’ve now spent more than four decades working on. And it’s the foundation of what’s now Wolfram Language—which I now feel justified in calling 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>”. What does this mean? It means that right in the language there’s a computational representation for both abstract and real things that we talk about in the world, whether those are <a href=\"https://reference.wolfram.com/language/guide/GraphsAndNetworks.html\">graphs</a> or <a href=\"https://reference.wolfram.com/language/guide/ImageProcessing.html\">images</a> or <a href=\"https://reference.wolfram.com/language/guide/DifferentialEquations.html\">differential equations</a>—or <a href=\"https://reference.wolfram.com/language/ref/entity/City.html\">cities</a> or <a href=\"https://reference.wolfram.com/language/ref/entity/Chemical.html\">chemicals</a> or <a href=\"https://reference.wolfram.com/language/ref/entity/Company.html\">companies</a> or <a href=\"https://reference.wolfram.com/language/ref/entity/Movie.html\">movies</a>. </p>\n<p>Why not just start with natural language? Well, that works up to a point—as the success of Wolfram|Alpha demonstrates. But once one’s trying to specify something more elaborate, natural language becomes (like “legalese”) at best unwieldy—and one really needs a more structured way to express oneself.</p>\n<p>There’s a big example of this historically, in mathematics. Back before about 500 years ago, pretty much the only way to “express math” was in natural language. But then mathematical notation was invented, and math took off—with the development of algebra, calculus, and eventually all the various mathematical sciences.</p>\n<p>My big goal with the Wolfram Language is to create a computational language that can do the same kind of thing for anything that can be “expressed computationally”. And to achieve this we’ve needed to build a language that both automatically does a lot of things, and intrinsically knows a lot of things. But the result is a language that’s set up so that people can conveniently “express themselves computationally”, much as traditional mathematical notation lets them “express themselves mathematically”. And a critical point is that—unlike traditional programming languages—Wolfram Language is intended not just for computers, but also for humans, to read. In other words, it’s intended as a structured way of “communicating computational ideas”, not just to computers, but also to humans.</p>\n<p>But now—with ChatGPT—this suddenly becomes even more important than ever before. Because—as we began to see above—ChatGPT can work with Wolfram Language, in a sense building up computational ideas just using natural language. And part of what’s then critical is that Wolfram Language can directly represent the kinds of things we want to talk about. But what’s also critical is that it gives us a way to “know what we have”—because we can realistically and economically read Wolfram Language code that ChatGPT has generated.</p>\n<p>The whole thing is beginning to work very nicely with the Wolfram plugin in ChatGPT. Here’s a simple example, where ChatGPT can readily generate a Wolfram Language version of what it’s being asked:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img28C.png' alt='Make a plot of Roman numerals' title='Make a plot of Roman numerals' width='620' height=''/></p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img29A.png' alt='Join the points' title='Join the points' width='622' height=''/></p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img30.png' alt='Show the code' title='Show the code' width='622' height='403'/></p>\n<p>And the critical point is that the “code” is something one can realistically expect to read (if I were writing it, I would use the slightly more compact <a href=\"https://reference.wolfram.com/language/ref/RomanNumeral.html\"><tt>RomanNumeral</tt></a> function):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw032223img31_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw032223img31.png' alt='' title='' width='558' height='62'> </div>\n</p></div>\n<p>Here’s another example:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img32A.png' alt='Make a histogram' title='Make a histogram' width='622' height=''/><br />\n<img src='https://content.wolfram.com/sites/43/2023/03/sw032223img33.png' alt='Show the code' title='Show the code' width='622' height='333'/></p>\n<p>I might have written the code a little differently, but this is again something very readable:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw032223img34_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw032223img34.png' alt='' title='' width='509' height='38'> </div>\n</p></div>\n<p>It’s often possible to use a pidgin of Wolfram Language and English to say what you want:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img35.png' alt='Create table' title='Create table' width='622' height='337'/><br />\n<img src='https://content.wolfram.com/sites/43/2023/03/sw032223img36.png' alt='Make ArrayPlot' title='Make ArrayPlot' width='622' height='1167/2'/></p>\n<p>Here’s an example where ChatGPT is again successfully constructing Wolfram Language—and conveniently shows it to us so we can confirm that, yes, it’s actually computing the right thing:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img37.png' alt='Alkali metal query' title='Alkali metal query' width='622' height='482'/></p>\n<p>And, by the way, to make this work it’s critical that the Wolfram Language is in a sense “self-contained”.

Or at least, a result. Because when we look at this computation, it might not be quite what we want. For example, we might want to pick out multiple dominant colors per country, and see if any of them are close to purple. But the whole Wolfram Language setup here makes it easy for us to “collaborate with the AI” to figure out what we want, and what to do.</p>\n<p>So far we’ve basically been starting with natural language, and building up Wolfram Language code. But we can also start with pseudocode, or code in some low-level programming language. And ChatGPT tends to do a remarkably good job of taking such things and producing well-written Wolfram Language code from them. The code isn’t always exactly right. But one can always run it (e.g. with the Wolfram plugin) and see what it does, potentially (courtesy of the symbolic character of Wolfram Language) line by line. And the point is that the high-level computational language nature of the Wolfram Language tends to allow the code to be sufficiently clear and (at least locally) simple that (particularly after seeing it run) one can readily understand what it’s doing—and then potentially iterate back and forth on it with the AI.</p>\n<p>When what one’s trying to do is sufficiently simple, it’s often realistic to specify it—at least if one does it in stages—purely with natural language, using Wolfram Language “just” as a way to see what one’s got, and to actually be able to run it. But it’s when things get more complicated that Wolfram Language really comes into its own—providing what’s basically the only viable human-understandable-yet-precise representation of what one wants. </p>\n<p>And when I was writing my book <em><a href=\"https://www.wolfram.com/language/elementary-introduction\">An Elementary Introduction to the Wolfram Language</a></em> this became particularly obvious. At the beginning of the book I was easily able to make up exercises where I described what was wanted in English. But as things started getting more complicated, this became more and more difficult. As a &#8220;fluent&#8221; user of Wolfram Language I usually immediately knew how to express what I wanted in Wolfram Language. But to describe it purely in English required something increasingly involved and complicated, that read like legalese.</p>\n<p>But, OK, so you specify something using Wolfram Language. Then one of the remarkable things ChatGPT is often able to do is to recast your Wolfram Language code so that it’s easier to read. It doesn’t (yet) always get it right. But it’s interesting to see it make different tradeoffs from a human writer of Wolfram Language code. For example, humans tend to find it difficult to come up with good names for things, making it usually better (or at least less confusing) to avoid names by having sequences of nested functions. But ChatGPT, with its command of language and meaning, has a fairly easy time making up reasonable names. And although it’s something I, for one, did not expect, I think using these names, and “spreading out the action”, can often make Wolfram Language code even easier to read than it was before, and indeed read very much like a formalized analog of natural language—that we can understand as easily as natural language, but that has a precise meaning, and can actually be run to generate computational results. </p>\n<h2 id=\"cracking-some-old-chestnuts\">Cracking Some Old Chestnuts</h2>\n<p>If you “know what computation you want to do”, and you can describe it in a short piece of natural language, then Wolfram|Alpha is set up to directly do the computation, and present the results in a way that is “visually absorbable” as easily as possible. But what if you want to describe the result in a narrative, textual essay? Wolfram|Alpha has never been set up to do that. But ChatGPT is. </p>\n<p>Here’s a result from Wolfram|Alpha:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img47A.png' alt='Altair versus Betelgeuse Wolfram|Alpha query' title='Altair versus Betelgeuse Wolfram|Alpha query' width='620' height=''/></p>\n<p>And here within ChatGPT we’re asking for this same Wolfram|Alpha result, but then telling ChatGPT to “make an essay out of it”:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img48A.png' alt='Altair-Betelgeuse essay' title='Altair-Betelgeuse essay' width='622' height=''/></p>\n<p>Another “old chestnut” for Wolfram|Alpha is math word problems. Given a “crisply presented” math problem, Wolfram|Alpha is likely to do very well at solving it. But what about a “woolly” word problem? Well, ChatGPT is pretty good at “unraveling” such things, and turning them into “crisp math questions”—which then the Wolfram plugin can now solve. Here’s an example:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img50A.png' alt='Math word problem' title='Math word problem' width='622' height=''/></p>\n<p>Here’s a slightly more complicated case, including a nice use of “common sense” to recognize that the number of turkeys cannot be negative:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img51A.png' alt='Math word problem' title='Math word problem' width='622' height=''/></p>\n<p>Beyond math word problems, another “old chestnut” now addressed by <nobr>ChatGPT + Wolfram</nobr> is what physicists tend to call “Fermi problems”: order-of-magnitude estimates that can be made on the basis of quantitative knowledge about the world. Here’s an example:</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/03/sw032223img54-v2.png' alt='Order-of-magnitude query' title='Order-of-magnitude query' width='622' height=''/></p>\n<h2 id=\"how-to-get-involved\">How to Get Involved</h2>\n<p><nobr>ChatGPT + Wolfram</nobr> is something very new—really a completely new kind of technology. And as happens whenever a new kind of technology arrives, it’s opening up tremendous new opportunities. Some of these we can already begin to to see—but lots of others will emerge over the weeks, months and years to come. </p>\n<p>So how can you get involved in what promises to be an exciting period of rapid technological—and conceptual—growth? The first thing is just to explore <nobr>ChatGPT + Wolfram</nobr>. ChatGPT and Wolfram are each on their own vast systems; the combination of them is something that it’ll take years to fully plumb. But the first step is just to get a sense of what’s possible. </p>\n<p>Find examples. <a href=\"https://community.wolfram.com/\">Share them</a>. Try to identify successful patterns of usage. And, most of all, try to find workflows that deliver the highest value. Those workflows could be quite elaborate. But they could also be quite simple—cases where once one sees what can be done, there’s an immediate “aha”. </p>\n<p>How can you best implement a workflow? Well, we’re trying to work out the best workflows for that. Within Wolfram Language we’re setting up flexible ways to call on things like ChatGPT, both <a href=\"https://resources.wolframcloud.com/PacletRepository/resources/1e47aeaf-9015-4ce7-bfdd-aae85980ca40/\">purely programmatically</a>, and in the context of the notebook interface. </p>\n<p>But what about from the ChatGPT side? Wolfram Language has a very open architecture, where a user can add or modify pretty much whatever they want. But how can you use this from ChatGPT? One thing is just to tell ChatGPT to include some specific piece of “initial” Wolfram Language code (maybe together with documentation)—then use something like the pidgin above to talk to ChatGPT about the functions or other things you’ve defined in that initial code. </p>\n<p>We’re planning to build increasingly streamlined tools for handling and sharing Wolfram Language code for use through ChatGPT. But one approach that already works is to submit functions for publication in the <a href=\"https://resources.wolframcloud.com/FunctionRepository\">Wolfram Function Repository</a>, then—once they’re published—refer to these functions in your conversation with ChatGPT.</p>\n<p>OK, but what about within ChatGPT itself? What kind of prompt engineering should you do to best interact with the Wolfram plugin? Well, we don’t know yet. It’s something that has to be explored—in effect as an exercise in AI education or AI psychology. A typical approach is to give some “pre-prompts” earlier in your ChatGPT session, then hope it’s “still paying attention” to those later on. (And, yes, it has a limited “attention span”, so sometimes things have to get repeated.) </p>\n<p>We’ve tried to give an overall prompt to tell ChatGPT basically how to use the Wolfram plugin—and we fully expect this prompt to evolve rapidly, as we learn more, and as the ChatGPT LLM is updated. But you can add your own general pre-prompts, saying things like “When using Wolfram always try to include a picture” or “Use SI units” or “Avoid using complex numbers if possible”. </p>\n<p>You can also try setting up a pre-prompt that essentially “defines a function” right in ChatGPT—something like: “If I give you an input consisting of a number, you are to use Wolfram to draw a polygon with that number of sides”. Or, more directly, “If I give you an input consisting of numbers you are to apply the following Wolfram function to that input &#8230;”, then give some explicit Wolfram Language code.</p>\n<p>But these are very early days, and no doubt there’ll be other powerful mechanisms discovered for “programming” <nobr>ChatGPT + Wolfram</nobr>. And I think we can confidently expect that the next little while will be an exciting time of high growth, where there’s lots of valuable “low-hanging fruit” to be picked by those who chose to get involved.</p>\n<h2 id=\"some-background-&#038;-outlook\">Some Background &#038; Outlook</h2>\n<p>Even a week ago it wasn’t clear what <nobr>ChatGPT + Wolfram</nobr> was going to be like—or how well it was going to work. But these things that are now moving so quickly are built on decades of earlier development. And in some ways the arrival of <nobr>ChatGPT + Wolfram</nobr> finally marries the two main approaches historically taken to AI—that have long been viewed as disjoint and incompatible. </p>\n<p><a href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/\">ChatGPT is basically a very large neural network</a>, trained to follow the “statistical” patterns of text it’s seen on the web, etc. The concept of neural networks—in a form surprisingly close to what’s used in ChatGPT—originated all the way back in the 1940s. But after some enthusiasm in the 1950s, interest waned. There was a resurgence in the early 1980s (and indeed I myself first looked at neural nets then). But it wasn’t until 2012 that serious excitement began to build about what might be possible with neural nets. And now a decade later—in a development whose success came as a big surprise even to those involved—we have ChatGPT.</p>\n<p>Rather separate from the “statistical” tradition of neural nets is the “symbolic” tradition for AI. And in a sense that tradition arose as an extension of the process of formalization developed for mathematics (and mathematical logic), particularly near the beginning of the twentieth century. But what was critical about it was that it aligned well not only with abstract concepts of computation, but also with actual digital computers of the kind that started to appear in the 1950s.</p>\n<p>The successes in what could really be considered “AI” were for a long time at best spotty. But all the while, the general concept of computation was showing tremendous and growing success. But how might “computation” be related to ways people think about things? For me, a crucial development was <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">my idea at the beginning of the 1980s</a> (building on earlier formalism from mathematical logic) that transformation rules for symbolic expressions might be a good way to represent computations at what amounts to a “human” level. </p>\n<p>At the time my main focus was on <a href=\"https://writings.stephenwolfram.com/2013/06/there-was-a-time-before-mathematica/\">mathematical and technical computation</a>, but I soon began to wonder whether similar ideas might be applicable to “general AI”. I suspected something like neural nets might have a role to play, but at the time I only figured out a bit about what would be needed—and not how to achieve it. Meanwhile, the core idea of transformation rules for symbolic expressions became the foundation for what’s now the Wolfram Language—and made possible the decades-long process of developing the full-scale computational language that we have today.</p>\n<p>Starting in the 1960s there’d been efforts among AI researchers to develop systems that could “understand natural language”, and “represent knowledge” and answer questions from it. Some of what was done turned into less ambitious but practical applications. But generally success was elusive. Meanwhile, as a result of what amounted to a <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">philosophical conclusion of basic science</a> I’d done in the 1990s, <a href=\"https://writings.stephenwolfram.com/2016/04/my-life-in-technology-as-told-at-the-computer-history-museum/\">I decided around 2005 to make an attempt</a> to build a general “computational knowledge engine” that could broadly answer factual and computational questions posed in natural language. It wasn’t obvious that such a system could be built, but we discovered that—with our underlying computational language, and with a lot of work—it could. And in 2009 we were able to release <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a>. </p>\n<p>And in a sense what made Wolfram|Alpha possible was that internally it had a clear, formal way to represent things in the world, and to compute about them. For us, “understanding natural language” wasn’t something abstract; it was the concrete process of translating natural language to structured computational language. </p>\n<p>Another part was assembling all the data, methods, models and algorithms needed to “know about” and “compute about” the world. And while we’ve greatly automated this, we’ve still always found that to ultimately “get things right” there’s no choice but to have actual human experts involved. And while there’s a little of what one might think of as “statistical AI” in the natural language understanding system of Wolfram|Alpha, the vast majority of Wolfram|Alpha—and Wolfram Language—operates in a hard, symbolic way that’s at least reminiscent of the tradition of symbolic AI. (That’s not to say that individual functions in Wolfram Language don’t use machine learning and statistical techniques; in recent years more and more do, and the Wolfram Language also has a whole built-in <a href=\"https://www.wolfram.com/language/core-areas/machine-learning/\">framework for doing machine learning</a>.)</p>\n<p>As I’ve <a href=\"https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/\">discussed elsewhere</a>, what seems to have emerged is that “statistical AI”, and particularly neural nets, are well suited for tasks that we humans “do quickly”, including—as we learn from ChatGPT—natural language and the “thinking” that underlies it. But the symbolic and in a sense “more rigidly computational” approach is what’s needed when one’s building larger “conceptual” or computational “towers”—which is what happens in math, exact science, and now all the “computational X” fields. </p>\n<p>And now <nobr>ChatGPT + Wolfram</nobr> can be thought of as the first truly large-scale statistical + symbolic “AI” system. In Wolfram|Alpha (which became an original core part of things like the Siri intelligent assistant) there was for the first time broad natural language understanding—with “understanding” directly tied to actual computational representation and computation. And now, 13 years later, we’ve seen in ChatGPT that pure “statistical” neural net technology, when trained from almost the entire web, etc. can do remarkably well at “statistically” generating “human-like” “meaningful language”. And in <nobr>ChatGPT + Wolfram</nobr> we’re now able to leverage the whole stack: from the pure “statistical neural net” of ChatGPT, through the “computationally anchored” natural language understanding of Wolfram|Alpha, to the whole computational language and computational knowledge of Wolfram Language.</p>\n<p>When we were first building Wolfram|Alpha we thought that perhaps to get useful results we’d have no choice but to engage in a conversation with the user. But we discovered that if we immediately generated rich, “visually scannable” results, we only needed a simple “Assumptions” or “Parameters” interaction—at least for the kind of information and computation seeking we expected of our users. (In <a href=\"https://www.wolfram.com/wolfram-alpha-notebook-edition/\">Wolfram|Alpha Notebook Edition</a> we nevertheless have a powerful example of how multistep computation can be done with natural language.) </p>\n<p><a href=\"https://writings.stephenwolfram.com/2010/11/programming-with-natural-language-is-actually-going-to-work/\">Back in 2010 we were already experimenting</a> with generating not just the Wolfram Language code of typical Wolfram|Alpha queries from natural language, but also “whole programs”. At the time, however—without modern LLM technology—that didn’t get all that far. But what we discovered was that—in the context of the symbolic structure of the Wolfram Language—even having small fragments of what amounts to code be generated by natural language was extremely useful. And indeed I, for example, use the <a href=\"https://reference.wolfram.com/language/workflow/EnterFreeFormInput.html\"><span class=\"kbd\"><kbd>ctrl</kbd><kbd>=</kbd></span> mechanism</a> in <a href=\"https://www.wolfram.com/notebooks/\">Wolfram Notebooks</a> countless times almost every day, for example to construct symbolic entities or quantities from natural language. We don’t yet know quite what the modern “LLM-enabled” version of this will be, but it’s likely to involve the rich human-AI “collaboration” that we discussed above, and that we can begin to see in action for the first time in <nobr>ChatGPT + Wolfram</nobr>.</p>\n<p>I see what’s happening now as a historic moment. For well over half a century the statistical and symbolic approaches to what we might call “AI” evolved largely separately. But now, in <nobr>ChatGPT + Wolfram</nobr> they’re being brought together. And while we’re still just at the beginning with this, I think we can reasonably expect tremendous power in the combination—and in a sense a new paradigm for “AI-like computation”, made possible by the arrival of ChatGPT, and now by its combination with Wolfram|Alpha and Wolfram Language in <nobr>ChatGPT + Wolfram</nobr>.</p>\n",

And how will we humans fit in?</p>\n<p>My goal here is to explore some of the science, technology—and philosophy—of what we can expect from AIs. I should say at the outset that this is a subject fraught with both intellectual and practical difficulty. And all I’ll be able to do here is give a snapshot of my current thinking—which will inevitably be incomplete—not least because, as I’ll discuss, trying to predict how history in an area like this will unfold is something that runs straight into an issue of basic science: 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>.<span id=\"more-46460\"></span></p>\n<p>But let’s start off by talking about that particularly dramatic example of AI that’s just arrived on the scene: ChatGPT. So <a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/'>what is ChatGPT</a>? Ultimately, it’s a computational system for generating text that’s been set up to follow the patterns defined by human-written text from billions of webpages, millions of books, etc. Give it a textual prompt and it’ll continue in a way that’s somehow typical of what it’s seen us humans write.</p>\n<p>The results (which ultimately rely on all sorts of specific engineering) are remarkably “human like”. And what makes this work is that whenever <a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#models-for-human-like-tasks'>ChatGPT has to “extrapolate”</a> beyond anything it’s explicitly seen from us humans it does so in ways that seem similar to what we as humans might do. </p>\n<p>Inside ChatGPT is something that’s actually computationally probably quite similar to a brain—with millions of simple elements (“neurons”) forming a “<a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#neural-nets'>neural net</a>” with billions of connections that have been “tweaked” through 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'>progressive process of training</a> until they successfully reproduce the patterns of human-written text seen on all those webpages, etc. Even without training the neural net would still produce some kind of text. But the key point is that it won’t be text that we humans consider meaningful. To get such text we need to build on all that “human context” defined by the webpages and other materials we humans have written. The “raw computational system” will just do “raw computation”; to get something aligned with us humans requires leveraging the detailed human history captured by all those pages on the web, etc.</p>\n<p>But so what do we get in the end? Well, it’s text that basically reads like it was written by a human. In the past we might have thought that human language was somehow a uniquely human thing to produce. But now we’ve got an AI doing it. So what’s left for us humans? Well, somewhere things have got to get started: in the case of text, there’s got to be a prompt specified that tells the AI “<a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#meaning-space-and-semantic-laws-of-motion'>what direction to go in</a>”. And this is the kind of thing we’ll see over and over again. Given a defined “goal”, an AI can automatically work towards achieving it. But it ultimately takes something beyond the raw computational system of the AI to define what us humans would consider a meaningful goal. And that’s where we humans come in.</p>\n<p>What does this mean at a practical, everyday level? Typically we use ChatGPT by telling it—using text—what we basically want. And then it’ll fill in a whole essay’s worth of text talking about it. We can think of this interaction as corresponding to a kind of “linguistic user interface” (that we might dub a “LUI”). In a graphical user interface (GUI) there’s core content that’s being rendered (and input) through some potentially elaborate graphical presentation. In the LUI provided by ChatGPT there’s instead core content that’s being rendered (and input) through a textual (“linguistic”) presentation.</p>\n<p>You might jot down a few “bullet points”. And in their raw form someone else would probably have a hard time understanding them. But through the LUI provided by ChatGPT those bullet points can be turned into an “essay” that can be generally understood—because it’s based on the “shared context” defined by everything from the billions of webpages, etc. on which ChatGPT has been trained.</p>\n<p>There’s something about this that might seem rather unnerving. In the past, if you saw a custom-written essay you’d reasonably be able to conclude that a certain irreducible human effort was spent in producing it. But with ChatGPT this is no longer true. Turning things into essays is now “free” and automated. “Essayification” is no longer evidence of human effort. </p>\n<p>Of course, it’s hardly the first time there’s been a development like this. Back when I was a kid, for example, seeing that a document had been typeset was basically evidence that someone had gone to the considerable effort of printing it on printing press. But then came desktop publishing, and it became basically free to make any document be elaborately typeset. </p>\n<p>And in a longer view, this kind of thing is basically a constant trend in history: what once took human effort eventually becomes automated and “free to do” through technology. There’s a direct analog of this in the realm of ideas: that with time higher and higher levels of abstraction are developed, that subsume what were formerly laborious details and specifics. </p>\n<p>Will this end? Will we eventually have automated everything? Discovered everything? Invented everything? At some level, we now know that the answer is a resounding no. Because one of the consequences of the phenomenon of computational irreducibility is that there’ll always be more computations to do—that can’t in the end be reduced by any finite amount of automation, discovery or invention. </p>\n<p>Ultimately, though, this will be a more subtle story. Because while there may always be more computations to do, it could still be that we as humans don’t care about them. And that somehow everything we care about can successfully be automated—say by AIs—leaving “nothing more for us to do”. </p>\n<p>Untangling this issue will be at the heart of questions about how we fit into the AI future. And in what follows we’ll see over and over again that what might at first essentially seem like practical matters of technology quickly get enmeshed with deep questions of science and philosophy.</p>\n<h2 id='intuition-from-the-computational-universe'>Intuition from the Computational Universe</h2>\n<p>I’ve already mentioned computational irreducibility a couple of times. And it turns out that this is part of a circle of rather deep—and at first surprising—ideas that I believe are crucial to thinking about the AI future. </p>\n<p>Most of our existing intuition about “machinery” and “automation” comes from a kind of “clockwork” view of engineering—in which we specifically build systems component by component to achieve objectives we want. And it’s the same with most software: we write it line by line to specifically do—step by step—whatever it is we want. And we expect that if we want our machinery—or software—to do complex things then the underlying structure of the machinery or software must somehow be correspondingly complex.</p>\n<p>So when I started exploring the whole computational universe of possible programs in the early 1980s it was a <a href='https://www.wolframscience.com/nks/chap-2--the-crucial-experiment/'>big surprise to discover</a> that things work quite differently there. And indeed even tiny programs—that effectively just apply very simple rules repeatedly—<a href='https://www.wolframscience.com/nks/p27--how-do-simple-programs-behave/'>can generate great complexity</a>. In our usual practice of engineering we haven’t seen this, because we’ve always specifically picked programs (or other structures) where we can readily foresee how they’ll behave, so that we can explicitly set them up to do what we want. But out in the computational universe it’s very common to see programs that just “intrinsically generate” great complexity, without us ever having to explicitly “put it in”.</p>\n<div style=\"width:20%; height:auto;float:right; margin-left:10px; margin-top:20px;\">\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/longca-1_copy.txt' data-c2c-type='text/html'> <img src='https://content.wolfram.com/sites/43/2023/03/longca-1.png' alt='' title=''></div>\n</div>\n<p><span></p>\n<p>And having discovered this, we realize that there’s actually a big example that’s been around forever: the natural world. And indeed it increasingly seems as if the “secret” that nature uses to make the complexity it so often shows is exactly to operate according to the rules of simple programs. (For about three centuries it seemed as if mathematical equations were the ultimate way to describe the natural world—but in the <a href='https://writings.stephenwolfram.com/2022/05/twenty-years-later-the-surprising-greater-implications-of-a-new-kind-of-science/'>past few decades</a>, and particularly poignantly with our recent <a href='https://www.wolframphysics.org/' target=_blank rel=noopener>Physics Project</a>, it’s become clear that simple programs are in general a more powerful approach.)</p>\n<p>How does all this relate to technology? Well, <a href='https://writings.stephenwolfram.com/2022/06/alien-intelligence-and-the-concept-of-technology/'>technology is about</a> taking what’s out there in the world, and harnessing it for human purposes. And there’s a fundamental tradeoff here. There may be some system out in nature that does amazingly complex things. But the question is whether we can “slice off” certain particular things that we humans happen to find useful. A donkey has all sorts of complex things going on inside. But at some point it was discovered that we can use it “technologically” to do the rather simple thing of pulling a cart.</p>\n<p>And when it comes to programs out in the computational universe it’s extremely common to <a href='https://www.wolframscience.com/nksonline/toc.html'>see ones that do amazingly complex things</a>. But the question is whether we can find some aspect of those things that’s useful to us. Maybe the program is good at <a href='https://www.wolframscience.com/nks/chap-7--mechanisms-in-programs-and-nature#sect-7-5--the-intrinsic-generation-of-randomness'>making pseudorandomness</a>. Or <a href='https://writings.stephenwolfram.com/2021/05/the-problem-of-distributed-consensus/'>distributedly determining consensus</a>. Or maybe it’s just doing its complex thing, and <a href='https://writings.stephenwolfram.com/2022/06/alien-intelligence-and-the-concept-of-technology/'>we don’t yet know any “human purpose”</a> that this achieves.</p>\n<p>One of the notable features of a system like ChatGPT is that it isn’t <a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/'>constructed in an “understand-every-step” traditional engineering way</a>. Instead one basically just starts from a “raw computational system” (in the case of ChatGPT, a neural net), then progressively tweaks it until its behavior aligns with the “human-relevant” examples one has. And this alignment is what makes the system “technologically useful”—to us humans.</p>\n<p>Underneath, though, it’s still a computational system, with all the potential “wildness” that implies. And free from the “technological objective” of “human-relevant alignment” the system might do all sorts of sophisticated things. But they might not be things that (at least at this time in history) we care about. Even though some putative alien (or our future selves) might.</p>\n<p>OK, but let’s come back to the “raw computation” side of things. There’s something very different about computation from all other kinds of “mechanisms” we’ve seen before. We might have a cart that can move forward. And we might have a stapler that can put staples in things. But carts and staplers do very different things; there’s no equivalence between them. But for computational systems (at least ones that don’t just always behave in obviously simple ways) there’s my <a href='https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/'>Principle of Computational Equivalence</a>—which implies that all these systems are in a sense equivalent in the kinds of computations they can do.</p>\n<p>This equivalence has many consequences. One of them is that one can expect to make something equally computationally sophisticated out of all sorts of different kinds of things—whether brain tissue or electronics, or some system in nature. And this is effectively where <a href='https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-6--computational-irreducibility'>computational irreducibility</a> comes from.</p>\n<p>One might think that given, say, some computational system based on a simple program it would always be possible for us—with our sophisticated brains, mathematics, computers, etc.—to “jump ahead” and figure out what the system will do before it’s gone through all the steps to do it. But the Principle of Computational Equivalence implies that this won’t in general be possible—because the system itself can be as computationally sophisticated as our brains, mathematics, computers, etc. are. So this means that the system will be computationally irreducible: the only way to find out what it does is effectively just to go through the same whole computational process that it does.</p>\n<p>There’s a prevailing impression that science will always eventually be able do better than this: that it’ll be able to make “predictions” that allow us to work out what will happen without having to trace through each step. And indeed over the past three centuries there’s been lots of success in doing this, mainly by using mathematical equations. But ultimately it turns out that this has only been possible because science has ended up concentrating on particular systems where these methods work (and then these systems have been used for engineering). But the reality is that many systems show computational irreducibility. And in the phenomenon of computational irreducibility science is in effect “deriving its own limitedness”.</p>\n<p>Contrary to traditional intuition, try as we might, in many systems we’ll never be able find “formulas” (or other “shortcuts”) that describe what’s going to happen in the systems—because the systems are simply computationally irreducible. And, yes, this represents a limitation on science, and on knowledge in general. But while at first this might seem like a bad thing, there’s also something fundamentally satisfying about it. Because if everything were computationally reducible, we could always “jump ahead” and find out what will happen in the end, say in our lives. But computational irreducibility implies that in general we can’t do that—so that in some sense “something irreducible is being achieved” by the passage of time.</p>\n<p>There are a great many consequences of computational irreducibility. Some—that <a href='https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/'>I have particularly explored recently</a>—are in the domain of basic science (for example, <a href='https://www.wolframphysics.org/' target=_blank rel=noopener>establishing core laws of physics</a> as we perceive them from the interplay of computational irreducibility and our computational limitations as observers). But computational irreducibility is also central in thinking about the AI future—and in fact I increasingly feel that it adds the single most important intellectual element needed to make sense of many of the most important questions about the potential roles of AIs and humans in the future.</p>\n<p>For example, from our traditional experience with engineering we’re used to the idea that to find out why something happened in a particular way we can just “look inside” a machine or program and “see what it did”. But when there’s <a href='https://writings.stephenwolfram.com/2019/06/testifying-at-the-senate-about-a-i-selected-content-on-the-internet/#open-up-the-ai'>computational irreducibility, that won’t work</a>. Yes, we could “look inside” and see, say, a few steps. But computational irreducibility implies that to find out what happened, we’d have to trace through all the steps. We can’t expect to find a <a href='https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/#what-can-one-understand'>“simple human narrative”</a> that “says why something happened”. </p>\n<p>But having said this, one feature of computational irreducibility is that within any computationally irreducible systems there must always be (ultimately, infinitely many) “pockets of computational reducibility” to be found. So for example, even though we can’t say in general what will happen, we’ll always be able to identify specific features that we can predict. (“The leftmost cell will always be black”, etc.) And as we’ll discuss later we can potentially think of technological (as well as scientific) progress as being intimately tied to the discovery of these “pockets of reducibility”. And in effect the existence of infinitely many such pockets is the reason that “there’ll always be inventions and discoveries to be made”.</p>\n<p>Another consequence of computational irreducibility has to do with trying to <a href='https://writings.stephenwolfram.com/2016/10/a-short-talk-on-ai-ethics/'>ensure things about the behavior of a system</a>. Let’s say one wants to set up an AI so it’ll “never do anything bad”. One might imagine that one could just come up with particular rules that ensure this. But as soon as the behavior of the system (or its environment) is computationally irreducible one will never be able to guarantee what will happen in the system. Yes, there may be particular computationally reducible features one can be sure about. But in general computational irreducibility implies that there’ll always be a “possibility of surprise” or the potential for “unintended consequences”. And the only way to systematically avoid this is to make the system not computationally irreducible—which means it can’t make use of the full power of computation.</p>\n<h2 id='&ldquo;ais-will-never-be-able-to-do-that&rdquo;'>&ldquo;AIs Will Never Be Able to Do That&rdquo;</h2>\n<p>We humans like to feel special, and feel as if there’s something “fundamentally unique” about us. Five centuries ago we thought we lived at the center of the universe. Now we just tend to think that there’s something about our intellectual capabilities that’s fundamentally unique and beyond anything else. But the progress of AI—and things like ChatGPT—keep on giving us more and more evidence that that’s not the case. And indeed my <a href='https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/'>Principle of Computational Equivalence</a> says something even more extreme: that at a fundamental computational level there’s just nothing fundamentally special about us at all—and that in fact we’re computationally just equivalent to lots of systems in nature, and even to simple programs.</p>\n<p>This broad equivalence is important in being able to make very general scientific statements (like the existence of computational irreducibility). But it also highlights how significant our specifics—our particular history, biology, etc.—are. It’s very much like with ChatGPT. We can have a generic (untrained) neural net with the same structure as ChatGPT, that can do certain “raw computation”. But what makes ChatGPT interesting—at least to us—is that it’s been trained with the “human specifics” described on billions of webpages, etc. In other words, for both us and ChatGPT there’s nothing computationally “generally special”. But there is something “specifically special”—and it’s the particular history we’ve had, particular knowledge our civilization has accumulated, etc. </p>\n<p>There’s a curious analogy here to our physical place in the universe. There’s a certain uniformity to the universe, which means there’s nothing “generally special” about our physical location. But at least to us there’s still something “specifically special” about it, because it’s only here that we have our particular planet, etc. At a deeper level, ideas based on our Physics Project have led to the <a href='https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/'>concept of the ruliad</a>: the unique object that is the entangled limit of all possible computational processes. And we can then view our whole <a href='https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/'>experience as “observers of the universe”</a> as consisting of sampling the ruliad at a particular place.</p>\n<p>It’s a bit abstract (and a long story, which I won’t go into in any detail here), but we can think of different possible observers as being both at different places in physical space, and at different places in rulial space—giving them different “points of view” about what happens in the universe. Human minds are in effect concentrated in a particular region of physical space (mostly on this planet) and a particular region of rulial space. And in rulial space different human minds—with their different experiences and thus different ways of thinking about the universe—are in slightly different places. Animal minds might be fairly close in rulial space. But other computational systems (like, say, the weather, which is sometimes said to “have a mind of its own”) are further away—as <a href='https://writings.stephenwolfram.com/2022/06/alien-intelligence-and-the-concept-of-technology/#face-to-face-with-alien-intelligence,-out-in-rulial-space'>putative aliens might also be</a>. </p>\n<p>So what about AIs? It depends what we mean by “AIs”. If we’re talking about computational systems that are set up to do “human-like things” then that means they’ll be close to us in rulial space. But insofar as “an AI” is an arbitrary computational system it can be anywhere in rulial space, and it can do anything that’s computationally possible—which is far broader than what we humans can do, or even think about. (As we’ll talk about later, as our intellectual paradigms—and ways of observing things—expand, the <a href='https://writings.stephenwolfram.com/2022/06/alien-intelligence-and-the-concept-of-technology/#the-evolution-of-purpose-and-the-colonization-of-rulial-space'>region of rulial space in which we humans operate</a> will correspondingly expand.)</p>\n<p>But, OK, just how “general” are the computations that we humans (and the AIs that follow us) are doing? We don’t know enough about the brain to be sure. But if we look at artificial neural net systems—like ChatGPT—we can potentially get some sense. And in fact the computations really don’t seem to be that “general”. In most neural net systems data that’s given as input just <a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/'>“ripples once through the system”</a> to produce output. It’s not like in a computational system like a <a href='https://www.wolframscience.com/nks/chap-3--the-world-of-simple-programs#sect-3-4--turing-machines'>Turing machine</a> where there can be arbitrary “recirculation of data”. And indeed without such “arbitrary recirculation” the computation is necessarily quite “shallow” and can’t ultimately show computational irreducibility. </p>\n<p>It’s a bit of a technical point, but one can ask whether ChatGPT, with its “re-feeding of text produced so far” can in fact achieve <a href='https://www.wolframscience.com/nks/p642--the-phenomenon-of-universality/'>arbitrary (“universal”) computation</a>. And I suspect that in some formal sense it can (or at least a sufficiently expanded analog of it can)—though by producing an extremely verbose piece of text that for example in effect lists successive (self-delimiting) states of a Turing machine tape, and in which finding “the answer” to a computation will take a bit of effort. But—<a href=\"https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/\">as I’ve discussed elsewhere</a>—in practice ChatGPT is presumably almost exclusively doing “quite shallow” computation.</p>\n<p>It’s an interesting feature of the history of practical computing that what one might consider “deep pure computations” (say in mathematics or science) were done for decades before <a href='https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/'>“shallow human-like computations” became feasible</a>. And the basic reason for this is that for “human-like computations” (like recognizing images or generating text) one needs to capture lots of “human context”, which requires having lots of “human-generated data” and the computational resources to store and process it. </p>\n<p>And, by the way, brains also seem to specialize in fundamentally shallow computations. And to do the kind of deeper computations that allow one to take advantage of more of what’s out there in the computational universe, one has to turn to computers. As we’ve discussed, there’s plenty out in the computational universe that we humans don’t (yet) care about: we just consider it “raw computation”, that doesn’t seem to be “achieving human purposes”. But as a practical matter it’s important to make a bridge between the things we humans do care about and think about, and what’s possible in the computational universe. And in a sense that’s at the core of the project I’ve put so much effort into in the <a href='https://www.wolfram.com/language/'>Wolfram Language</a> of creating a full-scale computational language that describes in computational terms the things we think about, and experience in the world.</p>\n<p>OK, people have been saying for years: “It’s nice that computers can do A and B, but only humans can do X”. What X is supposed to be has changed—and narrowed—over the years. And ChatGPT provides us with a major unexpected new example of something more that computers can do.</p>\n<p>So what’s left? People might say: “Computers can never show creativity or originality”. But—perhaps disappointingly—that’s surprisingly easy to get, and indeed just a bit of randomness “seeding” a computation can often do a pretty good job, as we saw years ago with our <a href='https://tones.wolfram.com/' target=_blank rel=noopener>WolframTones</a> music-generation system, and as we see today with ChatGPT’s writing. People might also say: “Computers can never show emotions”. But before we had a good way to generate human language we wouldn’t really have been able to tell. And now it already works pretty well to ask ChatGPT to write “happily”, “sadly”, etc. (In their raw form emotions in both humans and other animals are presumably associated with rather simple “global variables” like neurotransmitter concentrations.)</p>\n<p>In the past people might have said: “Computers can never show judgement”. But by now there are endless examples of machine learning systems that do well at reproducing human judgement in lots of domains. People might also say: “Computers don’t show common sense”. And by this they typically mean that in a particular situation a computer might locally give an answer, but there’s a global reason why that answer doesn’t make sense, that the computer “doesn’t notice”, but a person would. </p>\n<p>So how does ChatGPT do on this? Not too badly. In plenty of cases it correctly recognizes that “that’s not what I’ve typically read”. But, yes, it makes mistakes. Some of them have to do with it not being able to do—purely with its neural net—even slightly “deeper”computations. (And, yes, that’s something that <a href='https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/'>can often be fixed</a> by it calling <a href='https://www.wolframalpha.com/'>Wolfram|Alpha</a> as a tool.) But in other cases the problem seems to be that it can’t quite connect different domains well enough.</p>\n<p>It’s perfectly capable of doing simple (“SAT-style”) analogies. But when it comes to larger-scale ones it doesn’t manage them. My guess, though, is that it won’t take much scaling up before it starts to be able to make what seem like very impressive analogies (that most of us humans would never even be able to make)—at which point it’ll probably successfully show broader “common sense”. </p>\n<p>But so what’s left that humans can do, and AIs can’t? There’s—almost by definition—one fundamental thing: define what we would consider goals for what to do. We’ll talk more about this later. But for now we can note that any computational system, once “set in motion”, will just follow its rules and do what it does. But what “direction should it be pointed in”? That’s something that has to come from “outside the system”.</p>\n<p>So how does it work for us humans? Well, our goals are in effect defined by the whole web of history—both from biological evolution and from our cultural development—in which we are embedded. But ultimately the only way to truly participate in that web of history is to be part of it.</p>\n<p>Of course, we can imagine technologically emulating every “relevant” aspect of a brain—and indeed things like the success of ChatGPT may suggest that that’s easier to do than we might have thought. But that won’t be enough. To participate in the “human web of history” (as we’ll discuss later) we’ll have to emulate other aspects of “being human”—like moving around, being mortal, etc. And, yes, if we make an “artificial human” we can expect it (by definition) to show all the features of us humans.</p>\n<p>But while we’re still talking about AIs as—for example—“running on computers” or “being purely digital” then, at least as far as we’re concerned, they’ll have to “get their goals from outside”. One day (as we’ll discuss) there will no doubt be some kind of “civilization of AIs”—which will form its own web of history. But at this point there’s no reason to think that we’ll still be able to describe what’s going on in terms of goals that we recognize. In effect the AIs will at that point have left our domain of rulial space. And—as we’ll discuss—they’ll be operating more like the kind of systems we see in nature, where we can tell there’s computation going on, but we can’t describe it, except rather anthropomorphically, in terms of human goals and purposes.</p>\n<h2 id='will-there-be-anything-left-for-the-humans-to-do?'>Will There Be Anything Left for the Humans to Do?</h2>\n<p>It’s been an issue that’s been raised—with varying degrees of urgency—for centuries: with the advance of automation (and now AI), will there eventually be nothing left for humans to do? Back in the early days of our species, there was lots of hard work of hunting and gathering to do, just to survive. But at least in the developed parts of the world, that kind of work is now at best a distant historical memory.</p>\n<p>And yet at each stage in history—at least so far—there always seem to be other kinds of work that keep people busy. But there’s a pattern that increasingly seems to repeat. Technology in some way or another enables some new occupation. And eventually that occupation becomes widespread, and lots of people do it. But then there’s a technological advance, and the occupation gets automated—and people aren’t needed to do it anymore. But now there’s a new level of technology, that enables new occupations. And the cycle continues.</p>\n<p>A century ago the increasingly widespread use of telephones meant that more and more people worked as switchboard operators. But then telephone switching was automated—and those switchboard operators weren’t needed anymore. But with automated switching there could be huge development of telecommunications infrastructure, opening up all sorts of new types of jobs, that in aggregate employ vastly more people than were ever switchboard operators. </p>\n<p>Something somewhat similar happened with accounting clerks. Before there were computers, one needed to have people laboriously tallying up numbers. But with computers, that was all automated away. But with that automation came the ability to do more complex financial computations—which allowed for more complex financial transactions, more complex regulations, etc., which in turn led to all sorts of new types of jobs. </p>\n<p>And across a whole range of industries, it’s been the same kind of story. Automation obsoletes some jobs, but enables others. There’s quite often a gap in time, and a change in the skills that are needed. But at least so far there always seems to have been a broad frontier of jobs that have been made possible—but haven’t yet been automated.</p>\n<p>Will this at some point end? Will there come a time when everything we humans want (or at least need) is delivered automatically? Well, of course, that depends on what we want, and whether, for example, that evolves with what technology has made possible. But could we just decide that “enough is enough”; let’s stop here, and just let everything be automated?</p>\n<p>I don’t think so. And the reason is ultimately because of computational irreducibility. We try to get the world to be “just so”, say set up so we’re “predictably comfortable”. Well, the problem is that there’s inevitably computational irreducibility in the way things develop—not just in nature, but in things like societal dynamics too. And that means that things won’t stay “just so”. There’ll always be something unpredictable that happens; something that the automation doesn’t cover. </p>\n<p>At first we humans might just say “we don’t care about that”. But in time computational irreducibility will affect everything. So if there’s anything at all we care about (including, for example, not going extinct), we’ll eventually have to do something—and go beyond whatever automation was already set up.</p>\n<p>It’s easy to find practical examples. We might think that when computers and people are all connected in a seamless automated network, there’d be nothing more to do. But what about the “unintended consequence” of computer security issues? What might have seemed like a case where “technology finished things” quickly creates a new kind of job for people to do. And at some level, computational irreducibility implies that things like this must always happen. There must always be a “frontier”. At least if there’s anything at all we want to preserve (like not going extinct). </p>\n<p>But let’s come back to the situation here and now with AI. ChatGPT just automated all sorts of text-related tasks. It used to take lots of effort—and people—to write customized reports, letters, etc. But (at least so long as one’s dealing with situations where one doesn’t need 100% “correctness”) ChatGPT just automated a lot of that, so people aren’t needed for it anymore. But what will this mean? Well, it means that there’ll be a lot more customized reports, letters, etc. that can be produced. And that will lead to new kinds of jobs—managing, analyzing, validating etc. all that mass-customized text. Not to mention the need for prompt engineers (a job category that just didn’t exist until a few months ago), and what amount to AI wranglers, AI psychologists, etc.</p>\n<p>But let’s talk about today’s “frontier” of jobs that haven’t been “automated away”. There’s one category that in many ways seems surprising to still be “with us”: jobs that involve lots of mechanical manipulation, like construction, fulfillment, food preparation, etc. But there’s a missing piece of technology here: there isn’t yet good general-purpose robotics (as there is general-purpose computing), and we humans still have the edge in dexterity, mechanical adaptability, etc. But I’m quite sure that in time—and perhaps quite suddenly—the necessary technology will be developed (and, yes, I have ideas about how to do it). And this will mean that most of today’s “mechanical manipulation” jobs will be “automated away”—and won’t need people to do them.</p>\n<p>But then, just as in our other examples, this will mean that mechanical manipulation will become much easier and cheaper to do, and more of it will be done. Houses might routinely be built and dismantled. Products might routinely be picked up from wherever they’ve ended up, and redistributed. Vastly more ornate “food constructions” might become the norm. And each of these things—and many more—will open up new jobs. </p>\n<p>But will every job that exists in the world today “on the frontier” eventually be automated? What about jobs where it seems like a large part of the value is just “having a human be there”? Jobs like flying a plane where one wants the “commitment” of the pilot being there in the plane. Caregiver jobs where one wants the “connection” of a human being there. Sales or education jobs where one wants “human persuasion” or “human encouragement”. Today one might think “only a human can make one feel that way”. But that’s typically based on the way the job is done now. And maybe there’ll be different ways found that allow the essence of the task to be automated, almost inevitably opening up new tasks to be done.</p>\n<p>For example, something that in the past needed “human persuasion” might be “automated” by something like gamification—but then more of it can be done, with new needs for design, analytics, management, etc.</p>\n<p>We’ve been talking about “jobs”. And that term immediately brings to mind wages, economics, etc. And, yes, plenty of what people do (at least in the world as it is today) is driven by issues of economics. But plenty is also not. There are things we “just want to do”—as a “social matter”, for “entertainment”, for “personal satisfaction”, etc.</p>\n<p>Why do we want to do these things? Some of it seems intrinsic to our biological nature. Some of it seems determined by the “cultural environment” in which we find ourselves. Why might one walk on a treadmill? In today’s world one might explain that it’s good for health, lifespan, etc. But a few centuries ago, without modern scientific understanding, and with a different view of the significance of life and death, that explanation really wouldn’t work.</p>\n<p>What drives such changes in our view of what we “want to do”, or “should do”? Some seems to be driven by the pure “dynamics of society”, presumably with its own computational irreducibility. But some has to do with our ways of interacting with the world—both the increasing automation delivered by the advance of technology, and the increasing abstraction delivered by the advance of knowledge.</p>\n<p>And there seem to be similar “cycles” seen here as in the kinds of things we consider to be “occupations” or “jobs”. For a while something is hard to do, and serves as a good “pastime”. But then it gets “too easy” (“everybody now knows how to win at game X”, etc.), and something at a “higher level” takes its place.</p>\n<p>About our “base” biologically driven motivations it doesn’t seem like anything has really changed in the course of human history. But there are certainly technological developments that could have an effect in the future. Effective human immortality, for example, would change many aspects of our motivation structure. As would things like the ability to implant memories or, for that matter, implant motivations.</p>\n<p>For now, there’s a certain element of what we want to do that’s “anchored” by our biological nature. But at some point we’ll surely be able to emulate with a computer at least the essence of what our brains are doing (and indeed the success of things like ChatGPT makes it seems like the moment when that will happen is closer at hand than we might have thought). And at that point we’ll have the possibility of what amount to “<a href='https://writings.stephenwolfram.com/2017/05/a-new-kind-of-science-a-15-year-view/#box-of-a-trillion-souls'>disembodied human souls</a>”. </p>\n<p>To us today it’s very hard to imagine what the “motivations” of such a “disembodied soul” might be. Looked at “from the outside” we might “see the soul” doing things that “don’t make much sense” to us. But it’s like asking what someone from a thousand years ago would think about many of our activities today. These activities make sense to us today because we’re embedded in our whole “current framework”. But without that framework they don’t make sense. And so it will be for the “disembodied soul”. To us, what it does may not make sense. But to it, with its “current framework”, it will.</p>\n<p>Could we “learn how to make sense of it”? There’s likely to be a certain barrier of computational irreducibility: in effect the only way to “understand the soul of the future” is to retrace its steps to get to where it is. So from our vantage point today, we’re separated by a certain “irreducible distance”, in effect in rulial space.</p>\n<p>But could there be some science of the future that will at least tell us general things about how such “souls” behave? Even when there’s computational irreducibility we know that there will always be pockets of computational reducibility—and thus features of behavior that are predictable. But will those features be “interesting”, say from our vantage point today? Maybe some of them will be. Maybe they’ll show us some kind of metapsychology of souls. But inevitably they can only go so far. Because in order for those souls to even experience the passage of time there has to be computational irreducibility. If too much of what happens is too predictable, it’s as if “nothing is happening”—or at least nothing “meaningful”.</p>\n<p>And, yes, this is all tied up with <a href='https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence#sect-12-7--the-phenomenon-of-free-will'>questions about “free will”</a>. Even when there’s a disembodied soul that’s operating according to some completely deterministic underlying program, computational irreducibility means its behavior can still “seem free”—because nothing can “outrun it” and say what it’s going to be. And the “inner experience” of the disembodied soul can be significant: it’s “intrinsically defining its future”, not just “having its future defined for it”.</p>\n<p>One might have assumed that once everything is just “visibly operating” as “mere computation” it would necessarily be “soulless” and “meaningless”. But computational irreducibility is what breaks out of this, and what allows there to be something irreducible and “meaningful” achieved. And it’s the same phenomenon whether one’s talking about our life now in the physical universe, or a <a href='https://writings.stephenwolfram.com/2017/05/a-new-kind-of-science-a-15-year-view/#box-of-a-trillion-souls'>future “disembodied” computational existence</a>. Or in other words, even if absolutely everything—even our very existence—has been “automated by computation”, that doesn’t mean we can’t have a perfectly good “inner experience” of meaningful existence.</p>\n<h2 id='generalized-economics-and-the-concept-of-progress'>Generalized Economics and the Concept of Progress</h2>\n<p>If we look at human history—or, for that matter, the history of life on Earth—there’s a certain pervasive sense that there’s some kind of “progress” happening. But what fundamentally is this “progress”? One can view it as the process of things being done at a progressively “higher level”, so that in effect “more of what’s important” can happen with a given effort. This idea of “going to a higher level” takes many forms—but they’re all fundamentally about eliding details below, and being able to operate purely in terms of the “things one cares about”.</p>\n<p>In technology, this shows up as automation, in which what used to take lots of detailed steps gets packaged into something that can be done “with the push of a button”. In science—and the intellectual realm in general—it shows up as abstraction, where what used to involve lots of specific details gets packaged into something that can be talked about “purely collectively”. And in biology it shows up as some structure (ribosome, cell, wing, etc.) that can be treated as a “modular unit”. </p>\n<p>That it’s possible to “do things at a higher level” is a reflection of being able to find “pockets of computational reducibility”. And—as we mentioned above—the fact that (given underlying computational irreducibility) there are necessarily an infinite number of such pockets means that “progress can always go on forever”.</p>\n<p>When it comes to human affairs we tend to value such progress highly, because (at least for now) we live finite lives, and insofar as we “want more to happen”, “progress” makes that possible. It’s certainly not self-evident that having more happen is “good”; one might just “want a quiet life”. But there is one constraint that in a sense originates from the deep foundations of biology. </p>\n<p>If something doesn’t exist, then nothing can ever “happen to it”. So in biology, if one’s going to have anything “happen” with organisms, they’d better not be extinct. But the physical environment in which biological organisms exist is finite, with many resources that are finite. And given organisms with finite lives, there’s an inevitability to the process of biological evolution, and to the “competition” for resources between organisms.</p>\n<p>Will there eventually be an “ultimate winning organism”? Well, no, there can’t be—because of computational irreducibility. There’ll in a sense always be more to explore in the computational universe—more “raw computational material for possible organisms”. And given any “fitness criterion” (like—in a Turing machine analog—“living longer before halting”) there’ll always be a way to “do better” with it. </p>\n<p>One might still wonder, however, whether perhaps biological evolution—with its underlying process of random genetic mutation—could “get stuck” and never be able to discover some “way to do better”. And indeed simple models of evolution might give one the intuition that this would happen. But actual evolution seems more like deep learning with a large neural net—where one’s effectively operating in an extremely high-dimensional space where there’s typically always a “way to get there from here”, at least given enough time.</p>\n<p>But, OK, so from our history of biological evolution there’s a certain built-in sense of “competition for scarce resources”. And this sense of competition has (so far) also carried over to human affairs. And indeed it’s the basic driver for most of the processes of economics.</p>\n<p>But what if resources aren’t “scarce” anymore? What if progress—in the form of automation, or AI—makes it easy to “get anything one wants”? We might imagine robots building everything, AIs figuring everything out, etc. But there are still things that are inevitably scarce. There’s only so much real estate. Only one thing can be “the first ___”. And, in the end, if we have finite lives, we only have so much time.</p>\n<p>Still, the more efficient—or high level—the things we do (or have) are, the more we’ll be able to get done in the time we have. And it seems as if what we perceive as “economic value” is intimately connected with “making things higher level”. A finished phone is “worth more” than its raw materials. An organization is “worth more” than its separate parts. But what if we could have “infinite automation”? Then in a sense there’d be “infinite economic value everywhere”, and one might imagine there’d be “no competition left”.</p>\n<p>But once again computational irreducibility stands in the way. Because it tells us there’ll never be “infinite automation”, just as there’ll never be an ultimate winning biological organism. There’ll always be “more to explore” in the computational universe, and different paths to follow. </p>\n<p>What will this look like in practice? Presumably it’ll lead to all sorts of diversity. So that, for example, a chart of “what the components of an economy are” will become more and more fragmented; it won’t just be “the single winning economic activity is ___”. </p>\n<p>There is one potential wrinkle in this picture of unending progress. What if nobody cares? What if the innovations and discoveries just don’t matter, say to us humans? And, yes, there is of course plenty in the world that at any given time in history we don’t care about. That piece of silicon we’ve been able to pick out? It’s just part of a rock. Well, until we start making microprocessors out of it. </p>\n<p>But as we’ve discussed, as soon as we’re “operating at some level of abstraction” computational irreducibility makes it inevitable that we’ll eventually be exposed to things that “require going beyond that level”. </p>\n<p>But then—critically—there will be choices. There will be different paths to explore (or “mine”) in the computational universe—in the end infinitely many of them. And whatever the computational resources of AIs etc. might be, they’ll never be able to explore all of them. So something—or someone—will have to make a choice of which ones to take.</p>\n<p>Given a particular set of things one cares about at a particular point, one might successfully be able to automate all of them. But computational irreducibility implies there will always be a “frontier”, where choices have to be made. And there’s no “right answer”; no “theoretically derivable” conclusion. Instead, if we humans are involved, this is where we get to define what’s going to happen.</p>\n<p>How will we do that? Well, ultimately it’ll be based on our history—biological, cultural, etc. We’ll get to use all that irreducible computation that went into getting us to where we are to define what to do next. In a sense it’ll be something that goes “through us”, and that uses what we are. It’s the place where—even when there’s automation all around—there’s still always something us humans can “meaningfully” do.</p>\n<h2 id='how-can-we-tell-the-ais-what-to-do?'>How Can We Tell the AIs What to Do?</h2>\n<p>Let’s say we want an AI (or any computational system) to do a particular thing. We might think we could just set up its rules (or “program it”) to do that thing. And indeed for certain kinds of tasks that works just fine. But the deeper the use we make of computation, the more we’re going to run into computational irreducibility, and the less we’ll be able to know how to set up particular rules to achieve what we want.</p>\n<p>And then, of course, there’s the question of defining what “we want” in the first place. Yes, we could have specific rules that say what particular pattern of bits should occur at a particular point in a computation. But that probably won’t have much to do with the kind of overall “human-level” objective that we typically care about. And indeed for any objective we can even reasonably define, we’d better be able to coherently “form a thought” about it. Or, in effect, we’d better have some “human-level narrative” to describe it. </p>\n<p>But how can we represent such a narrative? Well, we have natural language—probably the single most important innovation in the history of our species. And what natural language fundamentally does is to allow us to talk about things at a “human level”. It’s made of words that we can think of as representing “human-level packets of meaning”. And so, for example, the word “chair” represents the human-level concept of a chair. It’s not referring to some particular arrangement of atoms. Instead, it’s referring to any arrangement of atoms that we can usefully conflate into the single human-level concept of a chair, and from which we can deduce things like the fact that we can expect to sit on it, etc.</p>\n<p>So, OK, when we’re “talking to an AI” can we expect to just say what we want using natural language? We can definitely get a certain distance—and indeed ChatGPT helps us get further than ever before. But as we try to make things more precise we run into trouble, and the language we need rapidly becomes increasingly ornate, as in the “legalese” of complex legal documents. So what can we do? If we’re going to keep things at the level of “human thoughts” we can’t “reach down” into all the computational details. But yet we want a precise definition of how what we might say can be implemented in terms of those computational details.</p>\n<p>Well, there’s a way to deal with this, and it’s one that I’ve personally devoted many decades to: it’s <a href='https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/'>the idea of computational language</a>. When we think about programming languages, they’re things that operate solely at the level of computational details, defining in more or less the native terms of a computer what the computer should do. But the point of a true computational language (and, yes, in the world today the <a href='https://www.wolfram.com/language/'>Wolfram Language</a> is the sole example) is to do something different: to define a precise way of talking in computational terms about things in the world (whether concretely countries or minerals, or abstractly computational or mathematical structures). </p>\n<p>Out in the computational universe, there’s immense diversity in the “raw computation” that can happen. But there’s only a thin sliver of it that we humans (at least currently) care about and think about. And we can view computational language as defining a bridge between the things we think about and what’s computationally possible. The <a href='https://reference.wolfram.com/language/'>functions in our computational language</a> (7000 or so of them in the Wolfram Language) are in effect like words in a human language—but now they have a precise grounding in the “bedrock” of explicit computation. And the point is to <a href='https://livestreams.stephenwolfram.com/category/live-ceoing/' target=_blank rel=noopener>design the computational language</a> so it’s convenient for us humans to think and express ourselves in (like a vastly expanded analog of mathematical notation), but so it can also be precisely implemented in practice on a computer.</p>\n<p>Given a piece of natural language it’s often possible to give a precise, computational interpretation of it—in computational language. And indeed this is exactly what happens in Wolfram|Alpha. Give a piece of natural language and the <a href='https://www.wolfram.com/natural-language-understanding/'>Wolfram|Alpha NLU system</a> will try to find an interpretation of it as computational language. And from this interpretation, it’s then up to the Wolfram Language to do the computation that’s specified, and give back the results—and potentially synthesize natural language to express them. </p>\n<p>As a practical matter, this setup is useful not only for humans, <a href='https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/'>but also for AIs—like ChatGPT</a>. Given a system that produces natural language, the Wolfram|Alpha NLU system can “catch” natural language it is “thrown”, and interpret it as computational language that precisely specifies a potentially irreducible computation to do.</p>\n<p>With both natural language and computational language one’s basically “directly saying what one wants”. But an alternative approach—more aligned with machine learning—is just to give examples, and (implicitly or explicitly) say “follow these”. Inevitably there <a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#what-is-a-model?'>has to be some underlying model</a> for how to do that following—typically in practice just defined by “what a neural net with a certain architecture will do”. But will the result be “right”? Well, the result will be whatever the neural net gives. But typically we’ll tend to consider it “right” if it’s somehow consistent with what we humans would have concluded. And in practice <a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#models-for-human-like-tasks'>this often seems to happen</a>, presumably because the actual architecture of our brains is somehow similar enough to the architecture of the neural nets we’re using.</p>\n<p>But what if we want to “know for sure” what’s going to happen—or, for example, that some particular “mistake” can never be made? Well then we’re presumably thrust back into computational irreducibility, with the result that there’s no way to know, for example, whether a particular set of training examples can lead to a system that’s capable of doing (or not doing) some particular thing.</p>\n<p>OK, but let’s say we’re setting up some AI system, and we want to make sure it “doesn’t do anything bad”. There are several levels of issues here. The first is to decide what we mean by “anything bad”. And, as we’ll discuss below, that in itself is very hard. But even if we could abstractly figure this out, how should we actually express it? We could give examples—but then the AI will inevitably have to “extrapolate” from them, in ways we can’t predict. Or we could <a href='https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/'>describe what we want in computational language</a>. It might be difficult to cover “every case” (as it is in present-day human laws, or complex contracts). But at least we as humans can read what we’re specifying. Though even in this case, there’s an issue of computational irreducibility: that given the specification it won’t be possible to work out all its consequences.</p>\n<p>What does all this mean? In essence it’s just a reflection of the fact that as soon as there’s “serious computation” (i.e. irreducible computation) involved, one isn’t going to be immediately able to say what will happen. (And in a sense that’s inevitable, because if one could say, it would mean the computation wasn’t in fact irreducible.) So, yes, we can try to “tell AIs what to do”. But it’ll be like many systems in nature (or, for that matter, people): you can set them on a path, but you can’t know for sure what will happen; you just have to wait and see.</p>\n<h2 id='a-world-run-by-ais'>A World Run by AIs</h2>\n<p>In the world today, there are already <a href='https://writings.stephenwolfram.com/2019/06/testifying-at-the-senate-about-a-i-selected-content-on-the-internet/'>plenty of things that are being done by AIs</a>. And, as we’ve discussed, there’ll surely be more in the future. But who’s “in charge”? Are we telling the AIs what to do, or are they telling us? Today it’s at best a mixture: AIs suggest content for us (for example from the web), and in general make all sorts of recommendations about what we should do. And no doubt in the future those recommendations will be even more extensive and tightly coupled to us: we’ll be recording everything we do, processing it with AI, and continually annotating with recommendations—say through augmented reality—everything we see. And in some sense things might even go beyond “recommendations”. If we have direct neural interfaces, then we might be making our brains just “decide” they want to do things, so that in some sense we become pure “puppets of the AI”.</p>\n<p>And beyond “personal recommendations” there’s also the question of AIs running the systems we use, or in fact running the whole infrastructure of our civilization. Today we ultimately expect people to make large-scale decisions for our world—often operating in systems of rules defined by laws, and perhaps aided by computation, and even what one might call AI. But there may well come a time when it seems as if AIs could just “do a better job than humans”, say at running a central bank or waging a war.</p>\n<p>One might ask how one would ever know if the AI would “do a better job”. Well, one could try tests, and run examples. But once again one’s faced with computational irreducibility. Yes, the particular tests one tries might work fine. But one can’t ultimately predict everything that could happen. What will the AI do if there’s suddenly a never-before-seen seismic event? We basically won’t know until it happens.</p>\n<p>But can we be sure the AI won’t do anything “crazy”? Could we—with some definition of “crazy”—effectively “prove a theorem” that the AI can never do that? For any realistically nontrivial definition of crazy we’ll again run into computational irreducibility—and this won’t be possible.</p>\n<p>Of course, if we’ve put a person (or even a group of people) “in charge” there’s also no way to “prove” that they won’t do anything “crazy”—and history shows that people in charge quite often have done things that, at least in retrospect, we consider “crazy”. But even though at some level there’s no more certainty about what people will do than about what AIs might do, we still get a certain comfort when people are in charge if we think that “we’re in it together”, and that if something goes wrong those people will also “feel the effects”.</p>\n<p>But still, it seems inevitable that lots of decisions and actions in the world will be taken directly by AIs. Perhaps it’ll be because this will be cheaper. Perhaps the results (based on tests) will be better. Or perhaps, for example, things will just have to be done too quickly and in numbers too large for us humans to be in the loop.</p>\n<p>But, OK, if a lot of what happens in our world is happening through AIs, and the AIs are effectively doing irreducible computations, what will this be like? We’ll be in a situation where things are “just happening” and we don’t quite know why. But in a sense we’ve very much been in this situation before. Because it’s what happens all the time in our interaction with nature.</p>\n<p>Processes in nature—like, for example, the weather—can be thought of as corresponding to computations. And much of the time there’ll be irreducibility in those computations. So we won’t be able to readily predict them. Yes, we can do natural science to figure out some aspects of what’s going to happen. But it’ll inevitably be limited. </p>\n<p>And so we can expect it to be with the “AI infrastructure” of the world. Things are happening in it—as they are in the weather—that we can’t readily predict. We’ll be able to say some things—though perhaps in ways that are closer to psychology or social science than to traditional exact science. But there’ll be surprises—like maybe some strange AI analog of a hurricane or an ice age. And in the end all we’ll really be able to do is to try to build up our human civilization so that such things “don’t fundamentally matter” to it. </p>\n<p>In a sense the picture we have is that in time there’ll be a whole “civilization of AIs” operating—like nature—in ways that we can’t readily understand. And like with nature, we’ll coexist with it.</p>\n<p>But at least at first we might think there’s an important difference between nature and AIs. Because we imagine that we don’t “pick our natural laws”—yet insofar as we’re the ones building the AIs we imagine we can “pick their laws”. But both parts of this aren’t quite right. Because in fact one of the implications of our <a href='https://www.wolframphysics.org/' target=_blank rel=noopener>Physics Project</a> is precisely that the laws of nature that <a href='https://writings.stephenwolfram.com/2021/03/what-is-consciousness-some-new-perspectives-from-our-physics-project/'>we perceive are the way they are because we are observers who are the way we are</a>. And on the AI side, computational irreducibility implies that we can’t expect to be able to determine the final behavior of the AIs just from knowing the underlying laws we gave them.</p>\n<p>But what will the “emergent laws” of the AIs be? Well, just like in physics, it’ll depend on how we “sample” the behavior of the AIs. If we look down at the level of individual bits, it’ll be like looking at molecular dynamics (or the behavior of atoms of space). But typically we won’t do this. And just like in physics, we’ll operate as computationally bounded observers—measuring only certain aggregated features of an underlying computationally irreducible process. But what will the “overall laws of AIs” be like? Maybe they’ll show close analogies to physics. Or maybe they’ll seem more like psychological theories (superegos for AIs?). But we can expect them in many ways to be like large-scale laws of nature of the kind we know.</p>\n<p>Still, there’s one more difference between at least our interaction with nature and with AIs. Because we have in effect been “co-evolving” with nature for billions of years—yet AIs are “new on the scene”. And through our co-evolution with nature we’ve developed all sorts of structural, sensory and cognitive features that allow us to “interact successfully” with nature. But with AIs we don’t have these. So what does this mean?</p>\n<p>Well, our ways of interacting with nature can be thought of as leveraging pockets of computational reducibility that exist in natural processes—to make things seem at least somewhat predictable to us. But without having found such pockets for AIs, we’re likely to be faced with much more “raw computational irreducibility”—and thus much more unpredictability. It’s been a conceit of modern times that—particularly with the help of science—we’ve been able to make more and more of our world predictable to us, though in practice a large part of what’s led to this is the way we’ve built and controlled the environment in which we live, and the things we choose to do. </p>\n<p>But for the new “AI world”, we’re effectively starting from scratch. And to make things predictable in that world may be partly a matter of some new science, but perhaps more importantly a matter of choosing how we set up our “way of life” around the AIs there. (And, yes, if there’s lots of unpredictability we may be back to more ancient points of view about the importance of fate—or we may view AIs as a bit like the Olympians of Greek mythology, duking it out among themselves and sometimes having an effect on mortals.)</p>\n<h2 id='governance-in-an-ai-world'>Governance in an AI World</h2>\n<p>Let’s say the world is effectively being run by AIs, but let’s assume that we humans have at least some control over what they do. Then what principles should we have them follow? And what, for example, <a href='https://writings.stephenwolfram.com/2016/10/a-short-talk-on-ai-ethics/'>should their “ethics” be</a>?</p>\n<p>Well, the first thing to say is that there’s no ultimate, theoretical “right answer” to this. There are many ethical and other principles that AIs could follow. And it’s basically just a choice which ones should be followed. </p>\n<p>When we talk about “principles” and “ethics” we tend to think more in terms of constraints on behavior than in terms of rules for generating behavior. And that means we’re dealing with something <a href='https://www.wolframscience.com/metamathematics/the-metamodeling-of-axiomatic-mathematics/'>more like mathematical axioms</a>, where we ask things like what theorems are true according to those axioms, and what are not. And that means there can be issues like <a href='https://www.wolframscience.com/nks/p798--implications-for-mathematics-and-its-foundations/'>whether the axioms are consistent—and whether they’re complete</a>, in the sense that they can “determine the ethics of anything”. But now, once again, we’re face to face with computational irreducibility, here in the form of Gödel’s theorem and its generalizations. </p>\n<p>And what this means is that it’s in general undecidable whether any given set of principles is inconsistent, or incomplete. One might “ask an ethical question”, and find that there’s a “proof chain” of unbounded length to determine what the answer to that question is within one’s specified ethical system, or whether there is even a consistent answer.</p>\n<p>One might imagine that somehow one could add axioms to “patch up” whatever issues there are. But Gödel’s theorem basically says that it’ll never work. It’s the same story as so often with computational irreducibility: there’ll always be “new situations” that can arise, that in this case can’t be captured by a finite set of axioms.</p>\n<p>OK, but let’s imagine we’re picking a collection of principles for AIs. What criteria could we use to do it? One might be that these principles won’t inexorably lead to a simple state—like one where the AIs are extinct, or have to keep looping doing the same thing forever. And there may be cases where one can readily see that some set of principles will lead to such outcomes. But most of the time, computational irreducibility (here in the form of things like the halting problem) will once again get in the way, and one won’t be able to tell what will happen, or successfully pick “viable principles” this way.</p>\n<p>So this means that there are going to be a wide range of principles that we could in theory pick. But presumably what we’ll want is to pick ones that make AIs give us humans some sort of “good time”, whatever that might mean. </p>\n<p>And a minimal idea might be to get AIs just to observe what we humans do, and then somehow imitate this. But most people wouldn’t consider this the right thing. They’d point out all the “bad” things people do. And they’d perhaps say “let’s have the AIs follow not what we actually do, but what we aspire to do”. </p>\n<p>But where should we get these aspirations from? Different people, and different cultures, can have very different aspirations—with very different resulting principles. So whose should we pick? And, yes, there are pitifully few—if any—principles that we truly find in common everywhere. (Though, for example, the major religions all tend to share things like respect for human life, the Golden Rule, etc.) </p>\n<p>But do we in fact have to pick one set of principles? Maybe some AIs can have some principles, and some can have others. Maybe it should be like different countries, or different online communities: different principles for different groups or in different places. </p>\n<p>Right now that doesn’t seem plausible, because technological and commercial forces have tended to make it seem as if powerful AIs always have to be centralized. But I expect that this is just a feature of the present time, and not something intrinsic to any “human-like” AI. </p>\n<p>So could everyone (and maybe every organization) have “their own AI” with its own principles? For some purposes this might work OK. But there are many situations where AIs (or people) can’t really act independently, and where there have to be “collective decisions” made.</p>\n<p>Why is this? In some cases it’s because everyone is in the same physical environment. In other cases it’s because if there’s to be social cohesion—of the kind needed to support even something like a language that’s useful for communication—then there has to be certain conceptual alignment. </p>\n<p>It’s worth pointing out, though, that at some level having a “collective conclusion” is effectively just a way of introducing certain computational reducibility to make it “easier to see what to do”. And potentially it can be avoided if one has enough computation capability. For example, one might assume that there has to be a collective conclusion about which side of the road cars should drive on. But that wouldn’t be true if every car had the computation capability to just compute a trajectory that would for example optimally weave around other cars using both sides of the road. </p>\n<p>But if we humans are going to be in the loop, we presumably need a certain amount of computational reducibility to make our world sufficiently comprehensible to us that we can operate in it. So that means there’ll be collective—“societal”—decisions to make. We might want to just tell the AIs to “make everything as good as it can be for us”. But inevitably there will be tradeoffs. Making a collective decision one way might be really good for 99% of people, but really bad for 1%; making it the other way might be pretty good for 60%, but pretty bad for 40%. So what should the AI do?</p>\n<p>And, of course, this is a classic problem of political philosophy, and there’s no “right answer”. And in reality the setup won’t be as clean as this. It may be fairly easy to work out some immediate effects of different courses of action. But inevitably one will eventually run into computational irreducibility—and “unintended consequences”—and so one won’t be able to say with certainty what the ultimate effects (good or bad) will be.</p>\n<p>But, OK, so how should one actually make collective decisions? There’s no perfect answer, but in the world today, democracy in one form or another is usually viewed as the best option. So how might AI affect democracy—and perhaps improve on it? Let’s assume first that “humans are still in charge”, so that it’s ultimately their preferences that matter. (And let’s also assume that humans are more or less in their “current form”: unique and unreplicable discrete entities that believe they have independent minds.)</p>\n<p>The basic setup for current democracy is computationally quite simple: discrete votes (or perhaps rankings) are given (sometimes with weights of various kinds), and then numerical totals are used to determine the winner (or winners). And with past technology this was pretty much all that could be done. But now there are some new elements. Imagine not casting discrete votes, but instead using computational language to write a computational essay to describe one’s preferences. Or imagine having a conversation with a linguistically enabled AI that can draw out and debate one’s preferences, and eventually summarize them in some kind of feature vector. Then imagine feeding computational essays or feature vectors from all “voters” to some AI that “works out the best thing to do”.</p>\n<p>Well, there are still the same political philosophy issues. It’s not like 60% of people voted for A and 40% for B, so one chose A. It’s much more nuanced. But one still won’t be able to make everyone happy all the time, and one has to have some base principles to know what to do about that. </p>\n<p>And there’s a higher-order problem in having an AI “rebalance” collective decisions all the time based on everything it knows about people’s detailed preferences (and perhaps their actions too): for many purposes—like us being able to “keep track of what’s going on”—it’s important to maintain consistency over time. But, yes, one could deal with this by having the AI somehow also weigh consistency in figuring out what to do.</p>\n<p>But while there are no doubt ways in which AI can “tune up” democracy, AI doesn’t seem—in and of itself—to deliver any fundamentally new solution for making collective decisions, and for governance in general.</p>\n<p>And indeed, in the end things always seem to come down to needing some fundamental set of principles about how one wants things to be. Yes, AIs can be the ones to implement these principles. But there are many possibilities for what the principles could be. And—at least if we humans are “in charge”—we’re the ones who are going to have to come up with them.</p>\n<p>Or, in other words, we need to come up with some kind of “<a href='https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/'>AI constitution</a>”. Presumably this constitution should basically be written in precise computational language (and, yes, we’re trying to make it possible for the Wolfram Language to be used), but inevitably (as yet another consequence of computational irreducibility) there’ll be “fuzzy” definitions and distinctions, that will rely on things like examples, “interpolated” by systems like neural nets. Maybe when such a constitution is created, there’ll be multiple “renderings” of it, which can all be applied whenever the constitution is used, with some mechanism for picking the “overall conclusion”. (And, yes, there’s potentially a certain <a href='https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/'>“observer-dependent” multicomputational character</a> to this.)</p>\n<p>But whatever its detailed mechanisms, what should the AI constitution say? Different people and groups of people will definitely come to different conclusions about it. And presumably—just as there are different countries, etc. today with different systems of laws—there’ll be different groups that want to adopt different AI constitutions. (And, yes, the same issues about collective decision making apply again when those AI constitutions have to interact.)</p>\n<p>But given an AI constitution, one has a base on which AIs can make decisions. And on top of this one imagines a <a href='https://writings.stephenwolfram.com/2019/05/a-world-run-with-code/'>huge network of computational contracts</a> that are autonomously executed, essentially to “run the world”. </p>\n<p>And this is perhaps one of those classic “what could possibly go wrong?” moments. An AI constitution has been agreed on, and now everything is being run efficiently and autonomously by AIs that are following it. Well, once again, computational irreducibility rears its head. Because however carefully the AI constitution is drafted, computational irreducibility implies that one won’t be able to foresee all its consequences: “unexpected” things will always happen—and some of them will undoubtedly be things “one doesn’t like”.</p>\n<p>In human legal systems there’s always a mechanism for adding “patches”—filling in laws or precedents that cover new situations that have come up. But if everything is being autonomously run by AIs there’s no room for that. Yes, we as humans might characterize “bad things that happen” as “bugs” that could be fixed by adding a patch. But the AI is just supposed to be operating—essentially axiomatically—according to its constitution, so it has no way to “see that it’s a bug”. </p>\n<p>Similar to what we discussed above, there’s an interesting analogy here with human law versus natural law. Human law is something we define and can modify. Natural law is something the universe just provides us (notwithstanding the issues about observers discussed above). And by “setting an AI constitution and letting it run” we’re basically forcing ourselves into a situation where the “civilization of the AIs” is some “independent stratum” in the world, that we essentially have to take as it is, and adapt to.</p>\n<p>Of course, one might wonder if the AI constitution could “automatically evolve”, say based on what’s actually seen to happen in the world. But one quickly returns to the exact same issues of computational irreducibility, where one can’t predict whether the evolution will be “right”, etc.</p>\n<p>So far, we’ve assumed that in some sense “humans are in charge”. But at some level that’s an issue for the AI constitution to define. It’ll have to define whether AIs have “independent rights”—just like humans (and, in many legal systems, some other entities too). Closely related to the question of independent rights for AIs is whether an AI can be considered autonomously “responsible for its actions”—or whether such responsibility must always ultimately rest with the (presumably human) creator or “programmer” of the AI. </p>\n<p>Once again, computational irreducibility has something to say. Because it implies that the behavior of the AI can go “irreducibly beyond” what its programmer defined. And in the end (as we discussed above) this is the same basic mechanism that allows us humans to effectively have “free will” even when we’re ultimately operating according to deterministic underlying natural laws. So if we’re going to claim that we humans have free will, and can be “<a href='https://www.wolframscience.com/nks/notes-12-7--responsibility-and-free-will/'>responsible for our actions</a>” (as opposed to having our actions always “dictated by underlying laws”) then we’d better claim the same for AIs.</p>\n<p>So just as a human builds up something irreducible and irreplaceable in the course of their life, so can an AI. As a practical matter, though, AIs can presumably be backed up, copied, etc.—which isn’t (yet) possible for humans. So somehow their individual instances don’t seem as valuable, even if the “last copy” might still be valuable. As humans, we might want to say “those AIs are something inferior; they shouldn’t have rights”. But things are going to get more entangled. Imagine a bot that no longer has an identifiable owner but that’s successfully befriending people (say on social media), and paying for its underlying operation from donations, ads, etc. Can we reasonably delete that bot? We might argue that “the bot can feel no pain”—but that’s not true of its human friends. But what if the bot starts doing “bad” things? Well, then we’ll need some form of “bot justice”—and pretty soon we’ll find ourselves building a whole human-like legal structure for the AIs.</p>\n<h2 id='so-will-it-end-badly?'>So Will It End Badly?</h2>\n<p>OK, so AIs will learn what they can from us humans, then they’ll fundamentally just be running as autonomous computational systems—much like nature runs as an autonomous computational system—sometimes “interacting with us”. What will they “do to us”? Well, what does nature “do to us”? In a kind of animistic way, we might attribute intentions to nature, but ultimately it’s just “following its rules” and doing what it does. And so it will be with AIs. Yes, we might think we can set things up to determine what the AIs will do. But in the end—insofar as the AIs are really making use of what’s possible in the computational universe—there’ll inevitably be computational irreducibility, and we won’t be able to foresee what will happen, or what consequences it will have.</p>\n<p>So will the dynamics of AIs in fact have “bad” effects—like, for example, wiping us out? Well, it’s perfectly possible nature could wipe us out too. But one has the feeling that—extraterrestrial “accidents” aside—the natural world around us is at some level enough in some kind of “equilibrium” that nothing too dramatic will happen. But AIs are something new. So maybe they’ll be different.</p>\n<p>And one possibility might be that AIs could “improve themselves” to produce a single “apex intelligence” that would in a sense dominate everything else. But here we can see computational irreducibility as coming to the rescue. Because it implies that there can never be a “best at everything” computational system. It’s a core result of the emerging field of metabiology: that whatever “achievement” you specify, there’ll always be a computational system somewhere out there in the computational universe that will exceed it. (A simple example is that there’s always a Turing machine that can be found that will <a href='https://www.wolframscience.com/nks/notes-12-8--longest-halting-times-in-turing-machines/'>exceed any upper bound you specify</a> on the time it takes to halt.)</p>\n<p>So what this means is that there’ll inevitably be a whole “ecosystem” of AIs—with no single winner. Of course, while that might be an inevitable final outcome, it might not be what happens in the shorter term. And indeed the current tendency to centralize AI systems has a certain danger of AI behavior becoming “unstabilized” relative to what it would be with a whole ecosystem of “AIs in equilibrium”.</p>\n<p>And in this situation there’s another potential concern as well. We humans are the product of a long struggle for life played out over the course of the history of biological evolution. And insofar as AIs inherit our attributes we might expect them to inherit a certain “drive to win”—perhaps also against us. And perhaps this is where the AI constitution becomes important: to define a “contract” that supersedes what AIs might “naturally” inherit from effectively observing our behavior. Eventually we can expect the AIs to “<a href='https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/'>independently reach equilibrium</a>”. But in the meantime, the AI constitution can help break their connection with our “competitive” history of biological evolution. </p>\n<h2 id='preparing-for-an-ai-world'>Preparing for an AI World</h2>\n<p>We’ve talked quite a bit about the ultimate future course of AIs, and their relation to us humans. But what about the short term? How today can we prepare for the growing capabilities and uses of AIs?</p>\n<p>As has been true throughout history, people who use tools tend to do better than those who don’t. Yes, you can go on doing by direct human effort what has now been successfully automated, but except in rare cases you’ll increasingly be left behind. And what’s now emerging is an <a href='https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/'>extremely powerful combination</a> of tools: neural-net-style AI for “immediate human-like tasks”, along with <a href='https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/'>computational language</a> for deeper access to the computational universe and computational knowledge. </p>\n<p>So what should people do with this? The highest leverage will come from figuring out new possibilities—things that weren’t possible before but have now “come into range” as a result of new capabilities. And as we discussed above, this is a place where we humans are inevitably central contributors—because we’re the ones who must define what we consider has value for us. </p>\n<p>So what does this mean for education? What’s worth learning now that so much has been automated? I think the fundamental answer is how to think as broadly and deeply as possible—calling on as much knowledge and as many paradigms as possible, and particularly making use of the computational paradigm, and ways of thinking about things that directly connect with what computation can help with.</p>\n<p>In the course of human history a lot of knowledge has been accumulated. But as ways of thinking have advanced, it’s become unnecessary to learn directly that knowledge in all its detail: instead one can learn things at a higher level, abstracting out many of the specific details. But in the past few decades something fundamentally new has come on the scene: computers and the things they enable. </p>\n<p>For the first time in history, it’s become realistic to truly automate intellectual tasks. The leverage this provides is completely unprecedented. And we’re only just starting to come to terms with what it means for what and how we should learn. But with all this new power there’s a tendency to think something must be lost. Surely it must still be worth learning all those intricate details—that people in the past worked so hard to figure out—of how to do some mathematical calculation, even though <a href='https://www.wolfram.com/mathematica/'>Mathematica</a> has been able to do it automatically for more than a third of a century? </p>\n<p>And, yes, at the right time it can be interesting to learn those details. But in the effort to understand and best make use of the intellectual achievements of our civilization, it makes much more sense to leverage the automation we have, and treat those calculations just as “building blocks” that can be put together in “finished form” to do whatever it is we want to do.</p>\n<p>One might think this kind of leveraging of automation would just be important for “practical purposes”, and for applying knowledge in the real world. But actually—as I have personally <a href='https://www.stephenwolfram.com/'>found repeatedly to great benefit</a> over the decades—it’s also crucial at a conceptual level. Because it’s only through automation that one can get enough examples and experience that one’s able to develop the intuition needed to reach a higher level of understanding.</p>\n<p>Confronted with the rapidly growing amount of knowledge in the world there’s been a tremendous tendency to assume that people must inevitably become more and more specialized. But with increasing success in the automation of intellectual tasks—and what we might broadly call AI—it becomes clear there’s an alternative: to make more and more use of this automation, so people can operate at a higher level, “integrating” rather than specializing.</p>\n<p>And in a sense this is the way to make the best use of our human capabilities: to let us concentrate on setting the “strategy” of what we want to do—delegating the details of how to do it to automated systems that can do it better than us. But, by the way, the very fact that there’s an AI that knows how to do something will no doubt make it easier for humans to learn how to do it too. Because—although we don’t yet have the complete story—it seems inevitable that with modern techniques AIs will be able to successfully “learn how people learn”, and effectively present things an AI “knows” in just the right way for any given person to absorb.</p>\n<p>So what should people actually learn? Learn how to use tools to do things. But also learn what things are out there to do—and learn facts to anchor how you think about those things. A lot of education today is about answering questions. But for the future—with AI in the picture—what’s likely to be more important is to learn how to ask questions, and how to figure out what questions are worth asking. Or, in effect, how to lay out an “intellectual strategy” for what to do.</p>\n<p>And to be successful at this, what’s going to be important is breadth of knowledge—and clarity of thinking. And when it comes to clarity of thinking, there’s again something new in modern times: the concept of <a href='https://writings.stephenwolfram.com/2016/09/how-to-teach-computational-thinking/'>computational thinking</a>. In the past we’ve had things like logic, and mathematics, as ways to structure thinking. But now we have something new: computation.</p>\n<p>Does that mean everyone should “learn to program” in some traditional programming language? No. Traditional programming languages are about telling computers what to do in their terms. And, yes, lots of humans do this today. But it’s something that’s fundamentally ripe for direct automation (as examples with ChatGPT already show). And what’s important for the long term is something different. It’s to use the computational paradigm as a structured way to think not about the operation of computers, but about both things in the world and abstract things.</p>\n<p>And crucial to this is <a href='https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/'>having a computational language</a>: a language for expressing things using the computational paradigm. It’s perfectly possible to express simple “everyday things” in plain, unstructured natural language. But to build any kind of serious “conceptual tower” one needs something more structured. And that’s what computational language is about.</p>\n<p>One can see a rough historical analog in the development of mathematics and mathematical thinking. Up until about half a millennium ago, mathematics basically had to be expressed in natural language. But then came mathematical notation—and from it a more streamlined approach to mathematical thinking, that eventually made possible all the various mathematical sciences. And it’s now the same kind of thing with computational language and the computational paradigm. Except that it’s a much broader story, in which for basically every field or occupation “X” there’s a “computational X” that’s emerging.</p>\n<p>In a sense the point of computational language (and all my efforts in the development of the <a href='https://www.wolfram.com/language/'>Wolfram Language</a>) is to be able to let people get “as automatically as possible” to computational X—and to let people express themselves using the full power of the computational paradigm. </p>\n<p>Something like <a href='https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/'>ChatGPT provides “human-like AI”</a> in effect by piecing together existing human material (like billions of words of human-written text). But computational language lets one tap directly into computation—and gives the ability to do fundamentally new things, that immediately leverage our human capabilities for defining intellectual strategy.</p>\n<p>And, yes, while traditional programming is likely to be largely obsoleted by AI, computational language is something that provides a permanent bridge between human thinking and the computational universe: a channel in which the automation is already done in the very design (and implementation) of the language—leaving in a sense an interface directly suitable for humans to learn, and to use as a basis to extend their thinking.</p>\n<p>But, OK, what about the future of discovery? Will AIs take over from us humans in, for example, “doing science”? I, for one, have used computation (and many things one might think of as AI) as a tool for scientific discovery for nearly half a century. And, yes, many of my discoveries have in effect been “made by computer”. But science is ultimately about connecting things to human understanding. And so far it’s taken a human to knit what the computer finds into the whole web of human intellectual history. </p>\n<p>One can certainly imagine, though, that an AI—even one rather like ChatGPT—could be quite successful in taking a “raw computational discovery” and “explaining” how it might relate to existing human knowledge. One could also imagine that the AI would be successful at identifying what aspects of some system in the world could be picked out to describe in some formal way. But—as is typical for the process of modeling in general—a key step is to decide “what one cares about”, and in effect in what direction to go in extending one’s science. And this—like so much else—is inevitably tied into the specifics of the goals we humans set ourselves.</p>\n<p>In the emerging AI world there are plenty of specific skills that won’t make sense for (most) humans to learn—just as today the advance of automation has obsoleted many skills from the past. But—as we’ve discussed—we can expect there to “be a place” for humans. And what’s most important for us humans to learn is in effect how to pick “where next to go”—and where, out of all the infinite possibilities in the computational universe, we should take human civilization.</p>\n<h2 id='afterword:-looking-at-some-actual-data'>Afterword: Looking at Some Actual Data</h2>\n<p>OK, so we’ve talked quite a bit about what might happen in the future. But what about <a href='https://www.wolframalpha.com/examples/society-and-culture/economic-data'>actual data from the past</a>? For example, what’s been the actual history of the evolution of jobs? Conveniently, in the US, the <a href='https://www.census.gov/' target=_blank rel=noopener>Census Bureau</a> has records of people’s occupations going back to 1850. Of course, many job titles have changed since then. Switchmen (on railroads), chainmen (in surveying) and sextons (in churches) aren’t really things anymore. And telemarketers, aircraft pilots and web developers weren’t things in 1850. But with a bit of effort, it’s possible to more or less match things up—at least if one aggregates into large enough categories. </p>\n<p>So here are pie charts of different job categories at 50-year intervals:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw031523img1a_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw031523img1a.png' alt='' title='' width='620' height=''> </div>\n</div>\n<p><span></p>\n<p>And, yes, in 1850 the US was firmly an agricultural economy, with just over half of all jobs being in agriculture. But as agriculture got more efficient—with the introduction of machinery, irrigation, better seeds, fertilizers, etc.—the fraction dropped dramatically, to just a few percent today. </p>\n<p>After agriculture, the next biggest category back in 1850 was construction (along with other real-estate-related jobs, mainly maintenance). And this is a category that for a century and a half hasn’t changed much in size (at least so far), presumably because, even though there’s been greater automation, this has just allowed buildings to be more complex.</p>\n<p>Looking at the pie charts above, we can see a clear trend towards greater diversification in jobs (and indeed the same thing is seen in the development of other economies around the world). It’s an old theory in economics that increasing specialization is related to economic growth, but from our point of view here, we might say that the very possibility of a more complex economy, with more niches and jobs, is a reflection of the inevitable presence of computational irreducibility, and the complex web of pockets of computational reducibility that it implies. </p>\n<p>Beyond the overall distribution of job categories, we can also look at trends in individual categories over time—with each one in a sense providing a certain window onto history:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw031523img2-1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/04/sw031523img2A-1.png' alt='' title='' width='620' height=''> </div>\n</p></div>\n<p>One can definitely see cases where the number of jobs decreases as a result of automation. And this happens not only in areas like agriculture and mining, but also for example in finance (fewer clerks and bank tellers), as well as in sales and retail (online shopping). Sometimes—as in the case of manufacturing—there’s a decrease of jobs partly because of automation, and partly because the jobs move out of the US (mainly to countries with lower labor costs). </p>\n<p>There are cases—like military jobs—where there are clear “exogenous” effects. And then there are cases like transportation+logistics where there’s a steady increase for more than half a century as technology spreads and infrastructure gets built up—but then things “saturate”, presumably at least partly as a result of increased automation. It’s a somewhat similar story with what I’ve called “technical operations”—with more “tending to technology” needed as technology becomes more widespread.</p>\n<p>Another clear trend is an increase in job categories associated with the world becoming an “organizationally more complicated place”. Thus we see increases in management, as well as administration, government, finance and sales (which all have recent decreases as a result of computerization). And there’s also a (somewhat recent) increase in legal. </p>\n<p>Other areas with increases include healthcare, engineering, science and education—where “more is known and there’s more to do” (as well as there being increased organizational complexity). And then there’s entertainment, and food+hospitality, with increases that one might attribute to people leading (and wanting) “more complex lives”. And, of course, there’s information technology which takes off from nothing in the mid-1950s (and which had to be rather awkwardly grafted into the data we’re using here).</p>\n<p>So what can we conclude? The data seems quite well aligned with what we discussed in more general terms above. Well-developed areas get automated and need to employ fewer people. But technology also opens up new areas, which employ additional people. And—as we might expect from computational irreducibility—things generally get progressively more complicated, with additional knowledge and organizational structure opening up more “frontiers” where people are needed. But even though there are sometimes “sudden inventions”, it still always seems to take decades (or effectively a generation) for there to be any dramatic change in the number of jobs. (The few sharp changes visible in the plots seem mostly to be associated with specific economic events, and—often related—changes in government policies.)</p>\n<p>But in addition to the different jobs that get done, there’s also the question of how individual people spend their time each day. And—while it certainly doesn’t live up to <a href='https://writings.stephenwolfram.com/2012/03/the-personal-analytics-of-my-life/'>my own (rather extreme) level of personal analytics</a>—there’s a certain amount of data on this that’s been collected over the years (by getting time diaries from randomly sampled people) in the <a href='https://www.ahtusdata.org/' target=_blank rel=noopener>American Heritage Time Use Study</a>. So here, for example, are plots based on this survey for how the amount of time spent on different broad activities has varied over the decades (the main line shows the mean—in hours—for each activity; the shaded areas indicate successive deciles):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw031523img3-1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw031523img3-1.png' alt='' title='' width='620' height=''> </div>\n</p></div>\n<p>And, yes, people are spending more time on “media &#038; computing”, some mixture of watching TV, playing videogames, etc. Housework, at least for women, takes less time, presumably mostly as a result of automation (appliances, etc.). (“Leisure” is basically “hanging out” as well as hobbies and social, cultural, sporting events, etc.; “Civic” includes volunteer, religious, etc. activities.) </p>\n<p>If one looks specifically at people who are doing paid work</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw031523img4-1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw031523img4.png' alt='' title='' width='620' height=''> </div>\n</p></div>\n<p>one notices several things. First, the average number of hours worked hasn’t changed much in half a century, though the distribution has broadened somewhat. For people doing paid work, media &#038; computing hasn’t increased significantly, at least since the 1980s. One category in which there is systematic increase (though the total time still isn’t very large) is exercise. </p>\n<p>What about people who—for one reason or another—aren’t doing paid work? Here are corresponding results in this case:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/03/sw031523img5-1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw031523img5.png' alt='' title='' width='620' height=''> </div>\n</p></div>\n<p>Not so much increase in exercise (though the total times are larger to begin with), but now a significant increase in media &#038; computing, with the average recently reaching nearly 6 hours per day for men—perhaps as a reflection of “more of life going online”.</p>\n<p>But looking at all these results on time use, I think the main conclusion that over the past half century, the ways people (at least in the US) spend their time have remained rather stable—even as we’ve gone from a world with almost no computers to a world in which there are more computers than people.</p>\n",

But how does it do it? And why does it work? My purpose here is to give a rough outline of what&#8217;s going on inside ChatGPT—and then to explore why it is that it can do so well in producing what we might consider to be meaningful text. I should say at the outset that I&#8217;m going to focus on the big picture of what&#8217;s going on—and while I&#8217;ll mention some engineering details, I won&#8217;t get deeply into them. (And the essence of what I&#8217;ll say applies just as well to other current &#8220;large language models&#8221; [LLMs] as to ChatGPT.)</p>\n<p>The first thing to explain is that what ChatGPT is always fundamentally trying to do is to produce a &#8220;reasonable continuation&#8221; of whatever text it&#8217;s got so far, where by &#8220;reasonable&#8221; we mean &#8220;what one might expect someone to write after seeing what people have written on billions of webpages, etc.&#8221;<span id=\"more-45835\"></span></p>\n<p>So let&#8217;s say we&#8217;ve got the text &#8220;<em>The best thing about AI is its ability to</em>&#8221;. Imagine scanning billions of pages of human-written text (say on the web and in digitized books) and finding all instances of this text—then seeing what word comes next what fraction of the time. ChatGPT effectively does something like this, except that (as I&#8217;ll explain) it doesn&#8217;t look at literal text; it looks for things that in a certain sense &#8220;match in meaning&#8221;. But the end result is that it produces a ranked list of words that might follow, together with &#8220;probabilities&#8221;:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img1_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img1.png' alt='' title='' width='453' height='137'> </div>\n</p></div>\n<p>And the remarkable thing is that when ChatGPT does something like write an essay what it&#8217;s essentially doing is just asking over and over again &#8220;given the text so far, what should the next word be?&#8221;—and each time adding a word. (More precisely, as I&#8217;ll explain, it&#8217;s adding a &#8220;token&#8221;, which could be just a part of a word, which is why it can sometimes &#8220;make up new words&#8221;.)</p>\n<p>But, OK, at each step it gets a list of words with probabilities. But which one should it actually pick to add to the essay (or whatever) that it&#8217;s writing? One might think it should be the &#8220;highest-ranked&#8221; word (i.e. the one to which the highest &#8220;probability&#8221; was assigned). But this is where a bit of voodoo begins to creep in. Because for some reason—that maybe one day we&#8217;ll have a scientific-style understanding of—if we always pick the highest-ranked word, we&#8217;ll typically get a very &#8220;flat&#8221; essay, that never seems to &#8220;show any creativity&#8221; (and even sometimes repeats word for word). But if sometimes (at random) we pick lower-ranked words, we get a &#8220;more interesting&#8221; essay.</p>\n<p>The fact that there&#8217;s randomness here means that if we use the same prompt multiple times, we&#8217;re likely to get different essays each time. And, in keeping with the idea of voodoo, there&#8217;s a particular so-called &#8220;temperature&#8221; parameter that determines how often lower-ranked words will be used, and for essay generation, it turns out that a &#8220;temperature&#8221; of 0.8 seems best. (It&#8217;s worth emphasizing that there&#8217;s no &#8220;theory&#8221; being used here; it&#8217;s just a matter of what&#8217;s been found to work in practice. And for example the concept of &#8220;temperature&#8221; is there because exponential distributions <a href=\"https://writings.stephenwolfram.com/2023/02/computational-foundations-for-the-second-law-of-thermodynamics/#textbook-thermodynamics\">familiar from statistical physics</a> happen to be being used, but there&#8217;s no &#8220;physical&#8221; connection—at least so far as we know.)</p>\n<p>Before we go on I should explain that for purposes of exposition I&#8217;m mostly not going to use the <a href=\"https://openai.com/blog/chatgpt/\" target=\"_blank\">full system that&#8217;s in ChatGPT</a>; instead I&#8217;ll usually work with a simpler <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/GPT2-Transformer-Trained-on-WebText-Data/\">GPT-2 system</a>, which has the nice feature that it&#8217;s small enough to be able to run on a standard desktop computer. And so for essentially everything I show I&#8217;ll be able to include explicit <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> code that you can immediately run on your computer. (Click any picture here to copy the code behind it.)</p>\n<p>For example, here&#8217;s how to get the table of probabilities above. First, we have to <a href=\"https://resources.wolframcloud.com/NeuralNetRepository\">retrieve the underlying &#8220;language model&#8221; neural net</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img2_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img2.png' alt='' title='' width='466' height='123'> </div>\n</p></div>\n<p>Later on, we&#8217;ll look inside this neural net, and talk about how it works.

But where do those probabilities come from? Let&#8217;s start with a simpler problem. Let&#8217;s consider generating English text one letter (rather than word) at a time. How can we work out what the probability for each letter should be?</p>\n<p>A very minimal thing we could do is just take a sample of English text, and calculate how often different letters occur in it.

OK, so now instead of generating our &#8220;words&#8221; a single letter at a time, let&#8217;s generate them looking at two letters at a time, using these &#8220;2-gram&#8221; probabilities. Here&#8217;s a sample of the result—which happens to include a few &#8220;actual words&#8221;:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img22_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img22.png' alt='' title='' width='500' height='38'> </div>\n</p></div>\n<p>With sufficiently much English text we can get pretty good estimates not just for probabilities of single letters or pairs of letters (2-grams), but also for longer runs of letters. And if we generate &#8220;random words&#8221; with progressively longer <em>n</em>-gram probabilities, we see that they get progressively &#8220;more realistic&#8221;:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img23_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img23.png' alt='' title='' width='586' height='158'> </div>\n</p></div>\n<p>But let&#8217;s now assume—more or less as ChatGPT does—that we&#8217;re dealing with whole words, not letters. There are about 40,000 <a href=\"https://reference.wolfram.com/language/ref/WordList.html\">reasonably commonly used words in English</a>. And by looking at a large corpus of English text (say a few million books, with altogether a few hundred billion words), we can get an <a href=\"https://reference.wolfram.com/language/ref/WordFrequencyData.html\">estimate of how common each word is</a>. And using this we can start generating &#8220;sentences&#8221;, in which each word is independently picked at random, with the same probability that it appears in the corpus. Here&#8217;s a sample of what we get:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img24_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img24.png' alt='' title='' width='494' height='38'> </div>\n</p></div>\n<p>Not surprisingly, this is nonsense. So how can we do better? Just like with letters, we can start taking into account not just probabilities for single words but probabilities for pairs or longer <em>n</em>-grams of words. Doing this for pairs, here are 5 examples of what we get, in all cases starting from the word &#8220;cat&#8221;:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img25_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img25.png' alt='' title='' width='453' height='134'> </div>\n</p></div>\n<p>It&#8217;s getting slightly more &#8220;sensible looking&#8221;. And we might imagine that if we were able to use sufficiently long <em>n</em>-grams we&#8217;d basically &#8220;get a ChatGPT&#8221;—in the sense that we&#8217;d get something that would generate essay-length sequences of words with the &#8220;correct overall essay probabilities&#8221;. But here&#8217;s the problem: there just isn&#8217;t even close to enough English text that&#8217;s ever been written to be able to deduce those probabilities. </p>\n<p>In a <a href=\"https://commoncrawl.org/\" target=\"_blank\" rel=\"noopener\">crawl of the web</a> there might be a few hundred billion words; in books that have been digitized there might be another hundred billion words. But with 40,000 common words, even the number of possible 2-grams is already 1.6 billion—and the number of possible 3-grams is 60 trillion. So there&#8217;s no way we can estimate the probabilities even for all of these from text that&#8217;s out there. And by the time we get to &#8220;essay fragments&#8221; of 20 words, the number of possibilities is larger than the number of particles in the universe, so in a sense they could never all be written down.</p>\n<p>So what can we do? The big idea is to make a model that lets us estimate the probabilities with which sequences should occur—even though we&#8217;ve never explicitly seen those sequences in the corpus of text we&#8217;ve looked at. And at the core of ChatGPT is precisely a so-called &#8220;large language model&#8221; (LLM) that&#8217;s been built to do a good job of estimating those probabilities. </p>\n<h2 id=\"what-is-a-model?\">What Is a Model?</h2>\n<p>Say you want to know (as <a href=\"https://archive.org/details/bub_gb_49d42xp-USMC/page/404/mode/2up\" target=\"_blank\" rel=\"noopener\">Galileo did back in the late 1500s</a>) how long it&#8217;s going to take a cannon ball dropped from each floor of the Tower of Pisa to hit the ground. Well, you could just measure it in each case and make a table of the results. Or you could do what is the essence of theoretical science: make a model that gives some kind of procedure for computing the answer rather than just measuring and remembering each case.</p>\n<p>Let&#8217;s imagine we have (somewhat idealized) data for how long the cannon ball takes to fall from various floors:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img26_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img26.png' alt='' title='' width='274' height='149'> </div>\n</p></div>\n<p>How do we figure out how long it&#8217;s going to take to fall from a floor we don&#8217;t explicitly have data about? In this particular case, we can use known laws of physics to work it out. But say all we&#8217;ve got is the data, and we don&#8217;t know what underlying laws govern it. Then we might make a mathematical guess, like that perhaps we should use a straight line as a model:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img27_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img27.png' alt='' title='' width='275' height='149'> </div>\n</p></div>\n<p>We could pick different straight lines. But this is the one that&#8217;s on average closest to the data we&#8217;re given. And from this straight line we can estimate the time to fall for any floor.</p>\n<p>How did we know to try using a straight line here? At some level we didn&#8217;t. It&#8217;s just something that&#8217;s mathematically simple, and we&#8217;re used to the fact that lots of data we measure turns out to be well fit by mathematically simple things. We could try something mathematically more complicated—say <em>a</em> + <em>b</em> <em>x</em> + <em>c</em> <em>x</em><sup>2</sup>—and then in this case we do better:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img29_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img29.png' alt='' title='' width='286' height='154'> </div>\n</p></div>\n<p>Things can go quite wrong, though.

And in the case of ChatGPT, lots of such &#8220;knobs&#8221; are used—actually, 175 billion of them.</p>\n<p>But the remarkable thing is that the underlying structure of ChatGPT—with &#8220;just&#8221; that many parameters—is sufficient to make a model that computes next-word probabilities &#8220;well enough&#8221; to give us reasonable essay-length pieces of text.</p>\n<h2 id=\"models-for-human-like-tasks\">Models for Human-Like Tasks</h2>\n<p>The example we gave above involves making a model for numerical data that essentially comes from simple physics—where we&#8217;ve known for several centuries that &#8220;simple mathematics applies&#8221;. But for ChatGPT we have to make a model of human-language text of the kind produced by a human brain. And for something like that we don&#8217;t (at least yet) have anything like &#8220;simple mathematics&#8221;. So what might a model of it be like?</p>\n<p>Before we talk about language, let&#8217;s talk about another human-like task: recognizing images. And as a simple example of this, let&#8217;s consider images of digits (and, yes, this is a <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/050b1a0a-f43a-4c28-b7e0-72607a918467/\">classic machine learning example</a>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img34_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img34.png' alt='' title='' width='397' height='56'> </div>\n</p></div>\n<p>One thing we could do is get a bunch of sample images for each digit:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img35_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img35.png' alt='' title='' width='312' height=''> </div>\n</p></div>\n<p>Then to find out if an image we&#8217;re given as input corresponds to a particular digit we could just do an explicit pixel-by-pixel comparison with the samples we have. But as humans we certainly seem to do something better—because we can still recognize digits, even when they&#8217;re for example handwritten, and have all sorts of modifications and distortions:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img36_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/03/sw021423img36-4.png' alt='' title='' width='541' height=''> </div>\n</p></div>\n<p>When we made a model for our numerical data above, we were able to take a numerical value <em>x</em> that we were given, and just compute <em>a + b x</em> for particular <em>a</em> and <em>b</em>. So if we treat the gray-level value of each pixel here as some variable <em>x<sub>i</sub></em> is there some function of all those variables that—when evaluated—tells us what digit the image is of? It turns out that it&#8217;s possible to construct such a function. Not surprisingly, it&#8217;s not particularly simple, though. And a typical example might involve perhaps half a million mathematical operations. </p>\n<p>But the end result is that if we feed the collection of pixel values for an image into this function, out will come the number specifying which digit we have an image of. Later, we&#8217;ll talk about how such a function can be constructed, and the idea of neural nets. But for now let&#8217;s treat the function as black box, where we feed in images of, say, handwritten digits (as arrays of pixel values) and we get out the numbers these correspond to:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img38_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img38.png' alt='' title='' width='565' height='58'> </div>\n</p></div>\n<p>But what&#8217;s really going on here? Let&#8217;s say we progressively blur a digit. For a little while our function still &#8220;recognizes&#8221; it, here as a &#8220;2&#8221;. But soon it &#8220;loses it&#8221;, and starts giving the &#8220;wrong&#8221; result:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img39_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img39.png' alt='' title='' width='528' height='58'> </div>\n</p></div>\n<p>But why do we say it&#8217;s the &#8220;wrong&#8221; result? In this case, we know we got all the images by blurring a &#8220;2&#8221;. But if our goal is to produce a model of what humans can do in recognizing images, the real question to ask is what a human would have done if presented with one of those blurred images, without knowing where it came from.</p>\n<p>And we have a &#8220;good model&#8221; if the results we get from our function typically agree with what a human would say. And the nontrivial scientific fact is that for an image-recognition task like this we now basically know how to construct functions that do this.</p>\n<p>Can we &#8220;mathematically prove&#8221; that they work? Well, no. Because to do that we&#8217;d have to have a mathematical theory of what we humans are doing. Take the &#8220;2&#8221; image and change a few pixels. We might imagine that with only a few pixels &#8220;out of place&#8221; we should still consider the image a &#8220;2&#8221;. But how far should that go? It&#8217;s a question of <a href=\"https://www.wolframscience.com/nks/chap-10--processes-of-perception-and-analysis#sect-10-7--visual-perception\">human visual perception</a>. And, yes, the answer would no doubt be different for bees or octopuses—and potentially <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/#alien-views-of-the-ruliad\">utterly different for putative aliens</a>.</p>\n<h2 id=\"neural-nets\">Neural Nets</h2>\n<p>OK, so how do our typical models for tasks like <a href=\"https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/\">image recognition</a> actually work? The most popular—and successful—current approach uses <a href=\"https://reference.wolfram.com/language/guide/NeuralNetworks.html\">neural nets</a>. Invented—in a form remarkably close to their use today—<a href=\"https://www.wolframscience.com/nks/notes-10-12--history-of-ideas-about-thinking/\">in the 1940s</a>, neural nets can be thought of as simple idealizations of how <a href=\"https://www.wolframscience.com/nks/notes-10-12--the-brain/\">brains seem to work</a>. </p>\n<p>In human brains there are about 100 billion neurons (nerve cells), each capable of producing an electrical pulse up to perhaps a thousand times a second. The neurons are connected in a complicated net, with each neuron having tree-like branches allowing it to pass electrical signals to perhaps thousands of other neurons. And in a rough approximation, whether any given neuron produces an electrical pulse at a given moment depends on what pulses it&#8217;s received from other neurons—with different connections contributing with different &#8220;weights&#8221;.</p>\n<p>When we &#8220;see an image&#8221; what&#8217;s happening is that when photons of light from the image fall on (&#8220;photoreceptor&#8221;) cells at the back of our eyes they produce electrical signals in nerve cells. These nerve cells are connected to other nerve cells, and eventually the signals go through a whole sequence of layers of neurons. And it&#8217;s in this process that we &#8220;recognize&#8221; the image, eventually &#8220;forming the thought&#8221; that we&#8217;re &#8220;seeing a 2&#8221; (and maybe in the end doing something like saying the word &#8220;two&#8221; out loud). </p>\n<p>The &#8220;black-box&#8221; function from the previous section is a &#8220;mathematicized&#8221; version of such a neural net.

Or, put a different way, if an image is somehow &#8220;<a href=\"https://www.wolframscience.com/nks/notes-10-12--memory-analogs-with-numerical-data/\">closer to being a 1</a>&#8221; than to being a 2, we want it to end up in the &#8220;1 place&#8221; and vice versa. </p>\n<p>As a straightforward analogy, let&#8217;s say we have certain positions in the plane, indicated by dots (in a real-life setting they might be positions of coffee shops). Then we might imagine that starting from any point on the plane we&#8217;d always want to end up at the closest dot (i.e. we&#8217;d always go to the closest coffee shop). We can represent this by dividing the plane into regions (&#8220;attractor basins&#8221;) separated by idealized &#8220;watersheds&#8221;:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img42_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img42.png' alt='' title='' width='204' height='205'> </div>\n</p></div>\n<p>We can think of this as implementing a kind of &#8220;recognition task&#8221; in which we&#8217;re not doing something like identifying what digit a given image &#8220;looks most like&#8221;—but rather we&#8217;re just, quite directly, seeing what dot a given point is closest to. (The &#8220;Voronoi diagram&#8221; setup we&#8217;re showing here separates points in 2D Euclidean space; the digit recognition task can be thought of as doing something very similar—but in a 784-dimensional space formed from the gray levels of all the pixels in each image.)</p>\n<p>So how do we make a neural net &#8220;do a recognition task&#8221;? Let&#8217;s consider this very simple case:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img43_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img43.png' alt='' title='' width='128' height='128'> </div>\n</p></div>\n<p>Our goal is to take an &#8220;input&#8221; corresponding to a position {<em>x</em>,<em>y</em>}—and then to &#8220;recognize&#8221; it as whichever of the three points it&#8217;s closest to.

Ultimately a neural net is a connected collection of idealized &#8220;neurons&#8221;—usually arranged in layers—with a simple example being:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img45_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img45.png' alt='' title='' width='199' height='241'> </div>\n</p></div>\n<p>Each &#8220;neuron&#8221; is effectively set up to evaluate a simple numerical function. And to &#8220;use&#8221; the network, we simply feed numbers (like our coordinates <em>x</em> and <em>y</em>) in at the top, then have neurons on each layer &#8220;evaluate their functions&#8221; and feed the results forward through the network—eventually producing the final result at the bottom:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img46_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img46.png' alt='' title='' width='253' height='244'> </div>\n</p></div>\n<p>In the traditional (biologically inspired) setup each neuron effectively has a certain set of &#8220;incoming connections&#8221; from the neurons on the previous layer, with each connection being assigned a certain &#8220;weight&#8221; (which can be a positive or negative number). The value of a given neuron is determined by multiplying the values of &#8220;previous neurons&#8221; by their corresponding weights, then adding these up and adding a constant—and finally applying a &#8220;thresholding&#8221; (or &#8220;activation&#8221;) function. In mathematical terms, if a neuron has inputs <nobr><em>x</em> = {<em>x</em><sub>1</sub>, <em>x</em><sub>2</sub> &#8230;}</nobr> then we compute <em>f</em>[<em>w</em> . <em>x</em> + <em>b</em>], where the weights <em>w</em> and constant <em>b</em> are generally chosen differently for each neuron in the network; the function <em>f </em>is usually the same.</p>\n<p>Computing <em>w</em> . <em>x</em> + <em>b</em> is just a matter of matrix multiplication and addition. The &#8220;activation function&#8221; <em>f</em> introduces nonlinearity (and ultimately is what leads to nontrivial behavior). Various activation functions commonly get used; here we&#8217;ll just use <tt><a href=\"http://reference.wolfram.com/language/ref/Ramp.html\">Ramp</a></tt> (or ReLU):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img48_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img48.png' alt='' title='' width='567' height='77'> </div>\n</p></div>\n<p>For each task we want the neural net to perform (or, equivalently, for each overall function we want it to evaluate) we&#8217;ll have different choices of weights. (And—as we&#8217;ll discuss later—these weights are normally determined by &#8220;training&#8221; the neural net using machine learning from examples of the outputs we want.)</p>\n<p>Ultimately, every neural net just corresponds to some overall mathematical function—though it may be messy to write out. For the example above, it would be:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img49_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img49.png' alt='' title='' width='542' height='115'> </div>\n</p></div>\n<p>The neural net of ChatGPT also just corresponds to a mathematical function like this—but effectively with billions of terms. </p>\n<p>But let&#8217;s go back to individual neurons. Here are some examples of the functions a neuron with two inputs (representing coordinates <em>x</em> and <em>y</em>) can compute with various choices of weights and constants (and <tt><a href=\"https://reference.wolfram.com/language/ref/Ramp.html\">Ramp</a></tt> as activation function):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img50_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img50.png' alt='' title='' width='499' height='115'> </div>\n</p></div>\n<p>But what about the larger network from above? Well, here&#8217;s what it computes:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img51_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img51.png' alt='' title='' width='472' height='206'> </div>\n</p></div>\n<p>It&#8217;s not quite &#8220;right&#8221;, but it&#8217;s close to the &#8220;nearest point&#8221; function we showed above.</p>\n<p>Let&#8217;s see what happens with some other neural nets. In each case, as we&#8217;ll explain later, we&#8217;re using machine learning to find the best choice of weights. Then we&#8217;re showing here what the neural net with those weights computes:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img52_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img52.png' alt='' title='' width='599' height='415'> </div>\n</p></div>\n<p>Bigger networks generally do better at approximating the function we&#8217;re aiming for. And in the &#8220;middle of each attractor basin&#8221; we typically get exactly the answer we want. But <a href=\"https://www.wolframscience.com/nks/notes-10-12--memory-analogs-with-numerical-data/\">at the boundaries</a>—where the neural net &#8220;has a hard time making up its mind&#8221;—things can be messier. </p>\n<p>With this simple mathematical-style &#8220;recognition task&#8221; it&#8217;s clear what the &#8220;right answer&#8221; is. But in the problem of recognizing handwritten digits, it&#8217;s not so clear. What if someone wrote a &#8220;2&#8221; so badly it looked like a &#8220;7&#8221;, etc.? Still, we can ask how a neural net distinguishes digits—and this gives an indication:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img53_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img53.png' alt='' title='' width='311' height='311'> </div>\n</p></div>\n<p>Can we say &#8220;mathematically&#8221; how the network makes its distinctions? Not really. It&#8217;s just &#8220;doing what the neural net does&#8221;. But it turns out that that normally seems to agree fairly well with the distinctions we humans make. </p>\n<p>Let&#8217;s take a more elaborate example. Let&#8217;s say we have images of cats and dogs. And we have a <a href=\"https://writings.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/\">neural net that&#8217;s been trained to distinguish them</a>. Here&#8217;s what it might do on some examples: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img54_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img54.png' alt='' title='' width='354' height='356'> </div>\n</p></div>\n<p>Now it&#8217;s even less clear what the &#8220;right answer&#8221; is. What about a dog dressed in a cat suit? Etc. Whatever input it’s given the neural net will generate an answer, and in a way reasonably consistent with how humans might. As I&#8217;ve said above, that&#8217;s not a fact we can &#8220;derive from first principles&#8221;. It&#8217;s just something that&#8217;s empirically been found to be true, at least in certain domains. But it&#8217;s a key reason why neural nets are useful: that they somehow capture a &#8220;human-like&#8221; way of doing things.</p>\n<p>Show yourself a picture of a cat, and ask &#8220;Why is that a cat?&#8221;. Maybe you&#8217;d start saying &#8220;Well, I see its pointy ears, etc.&#8221; But it&#8217;s not very easy to explain how you recognized the image as a cat. It&#8217;s just that somehow your brain figured that out. But for a brain there&#8217;s no way (at least yet) to &#8220;go inside&#8221; and see how it figured it out. What about for an (artificial) neural net? Well, it&#8217;s straightforward to see what each &#8220;neuron&#8221; does when you show a picture of a cat. But even to get a basic visualization is usually very difficult. </p>\n<p>In the final net that we used for the &#8220;nearest point&#8221; problem above there are 17 neurons. In the net for recognizing handwritten digits there are 2190. And in the net we&#8217;re using to recognize cats and dogs there are 60,650. Normally it would be pretty difficult to visualize what amounts to 60,650-dimensional space. But because this is a network set up to deal with images, many of its layers of neurons are organized into arrays, like the arrays of pixels it&#8217;s looking at.</p>\n<p>And if we take a typical cat image</p>\n<p><img src='https://content.wolfram.com/sites/43/2023/02/sw021423img55.png' alt='Cat' title='Cat' width='123/2' height='123/2'/></p>\n<p>then we can represent the states of neurons at the first layer by a collection of derived images—many of which we can readily interpret as being things like &#8220;the cat without its background&#8221;, or &#8220;the outline of the cat&#8221;:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img56_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img56.png' alt='' title='' width='599' height='355'> </div>\n</p></div>\n<p>By the 10th layer it&#8217;s harder to interpret what&#8217;s going on:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img57_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img57.png' alt='' title='' width='598' height='295'> </div>\n</p></div>\n<p>But in general we might say that the neural net is &#8220;picking out certain features&#8221; (maybe pointy ears are among them), and using these to determine what the image is of. But are those features ones for which we have names—like &#8220;pointy ears&#8221;? Mostly not. </p>\n<p>Are our brains using similar features? Mostly we don&#8217;t know. But it&#8217;s notable that the first few layers of a neural net like the one we&#8217;re showing here seem to pick out aspects of images (like edges of objects) that seem to be similar to ones we know are picked out by the first level of visual processing in brains.</p>\n<p>But let&#8217;s say we want a &#8220;theory of cat recognition&#8221; in neural nets. We can say: &#8220;Look, this particular net does it&#8221;—and immediately that gives us some sense of &#8220;how hard a problem&#8221; it is (and, for example, how many neurons or layers might be needed). But at least as of now we don&#8217;t have a way to &#8220;give a narrative description&#8221; of what the network is doing. And maybe that&#8217;s because it truly is computationally irreducible, and there&#8217;s no general way to find what it does except by explicitly tracing each step. Or maybe it&#8217;s just that we haven&#8217;t &#8220;figured out the science&#8221;, and identified the &#8220;natural laws&#8221; that allow us to summarize what&#8217;s going on.</p>\n<p>We&#8217;ll encounter the same kinds of issues when we talk about generating language with ChatGPT. And again it&#8217;s not clear whether there are ways to &#8220;summarize what it&#8217;s doing&#8221;. But the richness and detail of language (and our experience with it) may allow us to get further than with images.</p>\n<h2 id=\"machine-learning,-and-the-training-of-neural-nets\">Machine Learning, and the Training of Neural Nets</h2>\n<p>We&#8217;ve been talking so far about neural nets that &#8220;already know&#8221; how to do particular tasks. But what makes neural nets so useful (presumably also in brains) is that not only can they in principle do all sorts of tasks, but they can be incrementally &#8220;trained from examples&#8221; to do those tasks.</p>\n<p>When we make a neural net to distinguish cats from dogs we don&#8217;t effectively have to write a program that (say) explicitly finds whiskers; instead we just show lots of examples of what&#8217;s a cat and what&#8217;s a dog, and then have the network &#8220;machine learn&#8221; from these how to distinguish them.</p>\n<p>And the point is that the trained network &#8220;generalizes&#8221; from the particular examples it&#8217;s shown. Just as we&#8217;ve seen above, it isn&#8217;t simply that the network recognizes the particular pixel pattern of an example cat image it was shown; rather it&#8217;s that the neural net somehow manages to distinguish images on the basis of what we consider to be some kind of &#8220;general catness&#8221;. </p>\n<p>So how does neural net training actually work? Essentially what we&#8217;re always trying to do is to find weights that make the neural net successfully reproduce the examples we&#8217;ve given. And then we&#8217;re relying on the neural net to &#8220;interpolate&#8221; (or &#8220;generalize&#8221;) &#8220;between&#8221; these examples in a &#8220;reasonable&#8221; way.</p>\n<p>Let&#8217;s look at a problem even simpler than the nearest-point one above. Let&#8217;s just try to get a neural net to learn the function: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img58_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img58.png' alt='' title='' width='203' height='124'> </div>\n</p></div>\n<p>For this task, we&#8217;ll need a network that has just one input and one output, like: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img59_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img59.png' alt='' title='' width='141' height='170'> </div>\n</p></div>\n<p>But what weights, etc. should we be using? With every possible set of weights the neural net will compute some function. And, for example, here&#8217;s what it does with a few randomly chosen sets of weights: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img60_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img60.png' alt='' title='' width='597' height='209'> </div>\n</p></div>\n<p>And, yes, we can plainly see that in none of these cases does it get even close to reproducing the function we want. So how do we find weights that will reproduce the function?</p>\n<p>The basic idea is to supply lots of &#8220;input &#8594; output&#8221; examples to &#8220;learn from&#8221;—and then to try to find weights that will reproduce these examples. Here&#8217;s the result of doing that with progressively more examples:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img61_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img61.png' alt='' title='' width='597' height='259'> </div>\n</p></div>\n<p>At each stage in this &#8220;training&#8221; the weights in the network are progressively adjusted—and we see that eventually we get a network that successfully reproduces the function we want. So how do we adjust the weights? The basic idea is at each stage to see &#8220;how far away we are&#8221; from getting the function we want—and then to update the weights in such a way as to get closer. </p>\n<p>To find out &#8220;how far away we are&#8221; we compute what&#8217;s usually called a &#8220;loss function&#8221; (or sometimes &#8220;cost function&#8221;). Here we&#8217;re using a simple (L2) loss function that&#8217;s just the sum of the squares of the differences between the values we get, and the true values. And what we see is that as our training process progresses, the loss function progressively decreases (following a certain &#8220;learning curve&#8221; that&#8217;s different for different tasks)—until we reach a point where the network (at least to a good approximation) successfully reproduces the function we want:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img62_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img62.png' alt='' title='' width='581' height='200'> </div>\n</p></div>\n<p>Alright, so the last essential piece to explain is how the weights are adjusted to reduce the loss function. As we&#8217;ve said, the loss function gives us a &#8220;distance&#8221; between the values we&#8217;ve got, and the true values. But the &#8220;values we&#8217;ve got&#8221; are determined at each stage by the current version of neural net—and by the weights in it. But now imagine that the weights are variables—say <em>w<sub>i</sub></em>. We want to find out how to adjust the values of these variables to minimize the loss that depends on them.</p>\n<p>For example, imagine (in an incredible simplification of typical neural nets used in practice) that we have just two weights <em>w</em><sub>1</sub> and <em>w</em><sub>2</sub>.

But calculus comes to the rescue. As we mentioned above, one can always think of a neural net as computing a mathematical function—that depends on its inputs, and its weights. But now consider differentiating with respect to these weights. It turns out that the chain rule of calculus in effect lets us &#8220;unravel&#8221; the operations done by successive layers in the neural net. And the result is that we can—at least in some local approximation—&#8220;invert&#8221; the operation of the neural net, and progressively find weights that minimize the loss associated with the output.</p>\n<p>The picture above shows the kind of minimization we might need to do in the unrealistically simple case of just 2 weights. But it turns out that even with many more weights (ChatGPT uses 175 billion) it&#8217;s still possible to do the minimization, at least to some level of approximation. And in fact the big breakthrough in &#8220;deep learning&#8221; that occurred around 2011 was associated with the discovery that in some sense it can be easier to do (at least approximate) minimization when there are lots of weights involved than when there are fairly few.</p>\n<p>In other words—somewhat counterintuitively—it can be easier to solve more complicated problems with neural nets than simpler ones. And the rough reason for this seems to be that when one has a lot of &#8220;weight variables&#8221; one has a high-dimensional space with &#8220;lots of different directions&#8221; that can lead one to the minimum—whereas with fewer variables it&#8217;s easier to end up getting stuck in a local minimum (&#8220;mountain lake&#8221;) from which there&#8217;s no &#8220;direction to get out&#8221;.</p>\n<p>It&#8217;s worth pointing out that in typical cases there are many different collections of weights that will all give neural nets that have pretty much the same performance. And usually in practical neural net training there are lots of random choices made—that lead to &#8220;different-but-equivalent solutions&#8221;, like these:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img72_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img72.png' alt='' title='' width='571' height='82'> </div>\n</p></div>\n<p>But each such &#8220;different solution&#8221; will have at least slightly different behavior. And if we ask, say, for an &#8220;extrapolation&#8221; outside the region where we gave training examples, we can get dramatically different results:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img73_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img73.png' alt='' title='' width='571' height='83'> </div>\n</p></div>\n<p>But which of these is &#8220;right&#8221;? There&#8217;s really no way to say. They&#8217;re all &#8220;consistent with the observed data&#8221;. But they all correspond to different &#8220;innate&#8221; ways to &#8220;think about&#8221; what to do &#8220;outside the box&#8221;. And some may seem &#8220;more reasonable&#8221; to us humans than others. </p>\n<h2 id=\"the-practice-and-lore-of-neural-net-training\">The Practice and Lore of Neural Net Training</h2>\n<p>Particularly over the past decade, there&#8217;ve been many advances in the art of training neural nets. And, yes, it is basically an art. Sometimes—especially in retrospect—one can see at least a glimmer of a &#8220;scientific explanation&#8221; for something that&#8217;s being done. But mostly things have been discovered by trial and error, adding ideas and tricks that have progressively built a significant lore about how to work with neural nets.</p>\n<p>There are several key parts. First, there&#8217;s the matter of what architecture of neural net one should use for a particular task. Then there&#8217;s the critical issue of how one&#8217;s going to get the data on which to train the neural net. And increasingly one isn&#8217;t dealing with training a net from scratch: instead a new net can either directly incorporate another already-trained net, or at least can use that net to generate more training examples for itself.</p>\n<p>One might have thought that for every particular kind of task one would need a different architecture of neural net. But what&#8217;s been found is that the same architecture often seems to work even for apparently quite different tasks. At some level this reminds one of the <a href=\"https://www.wolframscience.com/nks/chap-11--the-notion-of-computation#sect-11-3--the-phenomenon-of-universality\">idea of universal computation</a> (and my <a href=\"https://www.wolframscience.com/nks/chap-12--the-principle-of-computational-equivalence/\">Principle of Computational Equivalence</a>), but, as I&#8217;ll discuss later, I think it&#8217;s more a reflection of the fact that the tasks we&#8217;re typically trying to get neural nets to do are &#8220;human-like&#8221; ones—and neural nets can capture quite general &#8220;human-like processes&#8221;.</p>\n<p>In earlier days of neural nets, there tended to be the idea that one should &#8220;make the neural net do as little as possible&#8221;. For example, in <a href=\"https://reference.wolfram.com/language/ref/SpeechRecognize.html\">converting speech to text</a> it was thought that one should first analyze the audio of the speech, break it into phonemes, etc. But what was found is that—at least for &#8220;human-like tasks&#8221;—it&#8217;s usually better just to try to train the neural net on the &#8220;end-to-end problem&#8221;, letting it &#8220;discover&#8221; the necessary intermediate features, encodings, etc. for itself.</p>\n<p>There was also the idea that one should introduce complicated individual components into the neural net, to let it in effect &#8220;explicitly implement particular algorithmic ideas&#8221;. But once again, this has mostly turned out not to be worthwhile; instead, it&#8217;s better just to deal with very simple components and let them &#8220;organize themselves&#8221; (albeit usually in ways we can&#8217;t understand) to achieve (presumably) the equivalent of those algorithmic ideas. </p>\n<p>That&#8217;s not to say that there are no &#8220;structuring ideas&#8221; that are relevant for neural nets. Thus, for example, having <a href=\"https://reference.wolfram.com/language/ref/ConvolutionLayer.html\">2D arrays of neurons with local connections</a> seems at least very useful in the early stages of processing images. And having patterns of connectivity that concentrate on &#8220;looking back in sequences&#8221; seems useful—as we&#8217;ll see later—in dealing with things like human language, for example in ChatGPT. </p>\n<p>But an important feature of neural nets is that—like computers in general—they&#8217;re ultimately just dealing with data. And current neural nets—with current approaches to neural net training—<a href=\"https://reference.wolfram.com/language/guide/NetEncoderDecoder.html\">specifically deal with arrays of numbers</a>. But in the course of processing, those arrays can be completely rearranged and reshaped. And as an example, <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/LeNet-Trained-on-MNIST-Data/\">the network we used for identifying digits above</a> starts with a 2D &#8220;image-like&#8221; array, quickly &#8220;thickening&#8221; to many channels, but then <a href=\"https://reference.wolfram.com/language/ref/AggregationLayer.html\">&#8220;concentrating down&#8221; into a 1D array</a> that will ultimately contain elements representing the different possible output digits:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img74_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img74.png' alt='' title='' width='287' height='182'> </div>\n</p></div>\n<p>But, OK, how can one tell how big a neural net one will need for a particular task? It&#8217;s something of an art. At some level the key thing is to know &#8220;how hard the task is&#8221;. But for human-like tasks that&#8217;s typically very hard to estimate. Yes, there may be a systematic way to do the task very &#8220;mechanically&#8221; by computer. But it&#8217;s hard to know if there are what one might think of as tricks or shortcuts that allow one to do the task at least at a &#8220;human-like level&#8221; vastly more easily. It might take <a href=\"https://writings.stephenwolfram.com/2022/06/games-and-puzzles-as-multicomputational-systems/\">enumerating a giant game tree</a> to &#8220;mechanically&#8221; play a certain game; but there might be a much easier (&#8220;heuristic&#8221;) way to achieve &#8220;human-level play&#8221;.</p>\n<p>When one&#8217;s dealing with tiny neural nets and simple tasks one can sometimes explicitly see that one &#8220;can&#8217;t get there from here&#8221;. For example, here&#8217;s the best one seems to be able to do on the task from the previous section with a few small neural nets: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img75_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img75.png' alt='' title='' width='498' height='395'> </div>\n</p></div>\n<p>And what we see is that if the net is too small, it just can&#8217;t reproduce the function we want. But above some size, it has no problem—at least if one trains it for long enough, with enough examples. And, by the way, these pictures illustrate a piece of neural net lore: that one can often get away with a smaller network if there&#8217;s a &#8220;squeeze&#8221; in the middle that forces everything to go through a smaller intermediate number of neurons. (It&#8217;s also worth mentioning that &#8220;no-intermediate-layer&#8221;—or so-called &#8220;<a href=\"https://en.wikipedia.org/wiki/Perceptron\" target=\"_blank\" rel=\"noopener\">perceptron</a>&#8221;—networks can only learn essentially linear functions—but as soon as there&#8217;s even one intermediate layer it&#8217;s <a href=\"https://en.wikipedia.org/wiki/Universal_approximation_theorem\" target=\"_blank\" rel=\"noopener\">always in principle possible</a> to approximate any function arbitrarily well, at least if one has enough neurons, though to make it feasibly trainable one typically has some kind of <a href=\"https://reference.wolfram.com/language/ref/BatchNormalizationLayer.html\">regularization or normalization</a>.)</p>\n<p>OK, so let&#8217;s say one&#8217;s settled on a certain neural net architecture. Now there&#8217;s the issue of getting data to train the network with. And many of the practical challenges around neural nets—and machine learning in general—center on acquiring or preparing the necessary training data. In many cases (&#8220;supervised learning&#8221;) one wants to get explicit examples of inputs and the outputs one is expecting from them. Thus, for example, one might want images tagged by what&#8217;s in them, or some other attribute. And maybe one will have to explicitly go through—usually with great effort—and do the tagging. But very often it turns out to be possible to piggyback on something that&#8217;s already been done, or use it as some kind of proxy. And so, for example, one might use alt tags that have been provided for images on the web. Or, in a different domain, one might use closed captions that have been created for videos. Or—for language translation training—one might use parallel versions of webpages or other documents that exist in different languages.</p>\n<p>How much data do you need to show a neural net to train it for a particular task? Again, it&#8217;s hard to estimate from first principles. Certainly the requirements can be dramatically reduced by using &#8220;transfer learning&#8221; to &#8220;transfer in&#8221; things like lists of important features that have already been learned in another network. But generally neural nets need to &#8220;see a lot of examples&#8221; to train well. And at least for some tasks it&#8217;s an important piece of neural net lore that the examples can be incredibly repetitive. And indeed it&#8217;s a standard strategy to just show a neural net all the examples one has, over and over again. In each of these &#8220;training rounds&#8221; (or &#8220;epochs&#8221;) the neural net will be in at least a slightly different state, and somehow &#8220;reminding it&#8221; of a particular example is useful in getting it to &#8220;remember that example&#8221;. (And, yes, perhaps this is analogous to the usefulness of repetition in human memorization.)</p>\n<p>But often just repeating the same example over and over again isn&#8217;t enough. It&#8217;s also necessary to show the neural net variations of the example. And it&#8217;s a feature of neural net lore that those &#8220;data augmentation&#8221; variations don&#8217;t have to be sophisticated to be useful. Just slightly modifying images with basic image processing can make them essentially &#8220;as good as new&#8221; for neural net training. And, similarly, when one&#8217;s run out of actual video, etc. for training self-driving cars, one can go on and just get data from running simulations in a model videogame-like environment without all the detail of actual real-world scenes.</p>\n<p>How about something like ChatGPT? Well, it has the nice feature that it can do &#8220;unsupervised learning&#8221;, making it much easier to get it examples to train from. Recall that the basic task for ChatGPT is to figure out how to continue a piece of text that it&#8217;s been given. So to get it &#8220;training examples&#8221; all one has to do is get a piece of text, and mask out the end of it, and then use this as the &#8220;input to train from&#8221;—with the &#8220;output&#8221; being the complete, unmasked piece of text. We&#8217;ll discuss this more later, but the main point is that—unlike, say, for learning what&#8217;s in images—there&#8217;s no &#8220;explicit tagging&#8221; needed; ChatGPT can in effect just learn directly from whatever examples of text it&#8217;s given.</p>\n<p>OK, so what about the actual learning process in a neural net? In the end it&#8217;s all about determining what weights will best capture the training examples that have been given. And there are all sorts of detailed choices and &#8220;hyperparameter settings&#8221; (so called because the weights can be thought of as &#8220;parameters&#8221;) that can be used to tweak how this is done. There are different <a href=\"https://reference.wolfram.com/language/ref/CrossEntropyLossLayer.html\">choices of loss function</a> (sum of squares, sum of absolute values, etc.). There are different ways to do loss minimization (how far in weight space to move at each step, etc.). And then there are questions like how big a &#8220;batch&#8221; of examples to show to get each successive estimate of the loss one&#8217;s trying to minimize. And, yes, one can apply machine learning (as we do, for example, in Wolfram Language) to automate machine learning—and to automatically set things like hyperparameters.</p>\n<p>But in the end the whole process of training can be characterized by seeing how the loss progressively decreases (as in this <a href=\"https://reference.wolfram.com/language/ref/NetTrain.html\">Wolfram Language progress monitor for a small training</a>):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img76_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img76.png' alt='' title='' width='261' height='327'> </div>\n</p></div>\n<p>And what one typically sees is that the loss decreases for a while, but eventually flattens out at some constant value. If that value is sufficiently small, then the training can be considered successful; otherwise it&#8217;s probably a sign one should try changing the network architecture. </p>\n<p>Can one tell how long it should take for the &#8220;learning curve&#8221; to flatten out? Like for so many other things, there seem to be approximate <a href=\"https://arxiv.org/pdf/2001.08361.pdf\" target=\"_blank\" rel=\"noopener\">power-law scaling relationships</a> that depend on the size of neural net and amount of data one&#8217;s using. But the general conclusion is that training a neural net is hard—and takes a lot of computational effort. And as a practical matter, the vast majority of that effort is spent doing operations on arrays of numbers, which is what GPUs are good at—which is why neural net training is typically limited by the availability of GPUs. </p>\n<p>In the future, will there be fundamentally better ways to train neural nets—or generally do what neural nets do? Almost certainly, I think. The fundamental idea of neural nets is to create a flexible &#8220;computing fabric&#8221; out of a large number of simple (essentially identical) components—and to have this &#8220;fabric&#8221; be one that can be incrementally modified to learn from examples. In current neural nets, one&#8217;s essentially using the ideas of calculus—applied to real numbers—to do that incremental modification. But it&#8217;s increasingly clear that having high-precision numbers doesn&#8217;t matter; 8 bits or less might be enough even with current methods. </p>\n<p>With <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-1--how-do-simple-programs-behave\">computational systems like cellular automata</a> that basically operate in parallel on many individual bits it&#8217;s never been clear <a href=\"https://content.wolfram.com/uploads/sites/34/2020/07/approaches-complexity-engineering.pdf\" target=\"_blank\" rel=\"noopener\">how to do this kind of incremental modification</a>, but there&#8217;s no reason to think it isn&#8217;t possible. And in fact, much like with the &#8220;<a href=\"https://en.wikipedia.org/wiki/AlexNet\" target=\"_blank\" rel=\"noopener\">deep-learning breakthrough of 2012</a>&#8221; it may be that such incremental modification will effectively be easier in more complicated cases than in simple ones.</p>\n<p>Neural nets—perhaps a bit like brains—are set up to have an essentially fixed network of neurons, with what&#8217;s modified being the strength (&#8220;weight&#8221;) of connections between them. (Perhaps in at least young brains significant numbers of wholly new connections can also grow.) But while this might be a convenient setup for biology, it&#8217;s not at all clear that it&#8217;s even close to the best way to achieve the functionality we need. And something that involves the equivalent of progressive network rewriting (perhaps reminiscent of our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a>) might well ultimately be better.</p>\n<p>But even within the framework of existing neural nets there&#8217;s currently a crucial limitation: neural net training as it&#8217;s now done is fundamentally sequential, with the effects of each batch of examples being propagated back to update the weights. And indeed with current computer hardware—even taking into account GPUs—most of a neural net is &#8220;idle&#8221; most of the time during training, with just one part at a time being updated. And in a sense this is because our current computers tend to have memory that is separate from their CPUs (or GPUs). But in brains it&#8217;s presumably different—with every &#8220;memory element&#8221; (i.e. neuron) also being a potentially active computational element. And if we could set up our future computer hardware this way it might become possible to do training much more efficiently.</p>\n<h2 id=\"surely-a-network-thats-big-enough-can-do-anything\">&#8220;Surely a Network That&#8217;s Big Enough Can Do Anything!&#8221; </h2>\n<p>The capabilities of something like ChatGPT seem so impressive that one might imagine that if one could just &#8220;keep going&#8221; and train larger and larger neural networks, then they&#8217;d eventually be able to &#8220;do everything&#8221;. And if one&#8217;s concerned with things that are readily accessible to immediate human thinking, it&#8217;s quite possible that this is the case. But the lesson of the past several hundred years of science is that there are things that can be figured out by formal processes, but aren&#8217;t readily accessible to immediate human thinking.</p>\n<p>Nontrivial mathematics is one big example. But the general case is really computation. And ultimately the issue is 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>. There are some computations which one might think would take many steps to do, but which can in fact be &#8220;reduced&#8221; to something quite immediate. But the discovery of computational irreducibility implies that this doesn&#8217;t always work. And instead there are processes—probably like the one below—where to work out what happens inevitably requires essentially tracing each computational step:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img77_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img77.png' alt='' title='' width='553' height='279'> </div>\n</p></div>\n<p>The kinds of things that we normally do with our brains are presumably specifically chosen to avoid computational irreducibility. It takes special effort to do math in one&#8217;s brain. And it&#8217;s in practice largely impossible to &#8220;think through&#8221; the steps in the operation of any nontrivial program just in one&#8217;s brain. </p>\n<p>But of course for that we have computers. And with computers we can readily do long, computationally irreducible things. And the key point is that there&#8217;s in general no shortcut for these. </p>\n<p>Yes, we could memorize lots of specific examples of what happens in some particular computational system. And maybe we could even see some (&#8220;computationally reducible&#8221;) patterns that would allow us to do a little generalization. But the point is that computational irreducibility means that we can never guarantee that the unexpected won&#8217;t happen—and it&#8217;s only by explicitly doing the computation that you can tell what actually happens in any particular case.</p>\n<p>And in the end there&#8217;s just a fundamental tension between learnability and computational irreducibility. Learning involves in effect <a href=\"https://www.wolframscience.com/nks/chap-10--processes-of-perception-and-analysis/\">compressing data by leveraging regularities</a>. But computational irreducibility implies that ultimately there&#8217;s a limit to what regularities there may be.</p>\n<p>As a practical matter, one can imagine building little computational devices—like cellular automata or Turing machines—into trainable systems like neural nets. And indeed such devices can serve as good &#8220;tools&#8221; for the neural net—like <a href=\"https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/\">Wolfram|Alpha can be a good tool for ChatGPT</a>. But computational irreducibility implies that one can&#8217;t expect to &#8220;get inside&#8221; those devices and have them learn.</p>\n<p>Or put another way, there&#8217;s an ultimate tradeoff between capability and trainability: the more you want a system to make &#8220;true use&#8221; of its computational capabilities, the more it&#8217;s going to show computational irreducibility, and the less it&#8217;s going to be trainable. And the more it&#8217;s fundamentally trainable, the less it&#8217;s going to be able to do sophisticated computation.</p>\n<p>(For ChatGPT as it currently is, the situation is actually much more extreme, because the neural net used to generate each token of output is a pure &#8220;feed-forward&#8221; network, without loops, and therefore has no ability to do any kind of computation with nontrivial &#8220;control flow&#8221;.)</p>\n<p>Of course, one might wonder whether it&#8217;s actually important to be able to do irreducible computations. And indeed for much of human history it wasn&#8217;t particularly important. But our modern technological world has been built on engineering that makes use of at least mathematical computations—and increasingly also more general computations. And if we look at the natural world, it&#8217;s <a href=\"https://www.wolframscience.com/nks/chap-8--implications-for-everyday-systems/\">full of irreducible computation</a>—that we&#8217;re slowly understanding how to emulate and use for our technological purposes. </p>\n<p>Yes, a neural net can certainly notice the kinds of regularities in the natural world that we might also readily notice with &#8220;unaided human thinking&#8221;. But if we want to work out things that are in the purview of mathematical or computational science the neural net isn&#8217;t going to be able to do it—unless it effectively &#8220;uses as a tool&#8221; an &#8220;ordinary&#8221; computational system.</p>\n<p>But there&#8217;s something potentially confusing about all of this. In the past there were plenty of tasks—including writing essays—that we&#8217;ve assumed were somehow &#8220;fundamentally too hard&#8221; for computers. And now that we see them done by the likes of ChatGPT we tend to suddenly think that computers must have become vastly more powerful—in particular surpassing things they were already basically able to do (like progressively computing the behavior of computational systems like cellular automata). </p>\n<p>But this isn&#8217;t the right conclusion to draw. Computationally irreducible processes are still computationally irreducible, and are still fundamentally hard for computers—even if computers can readily compute their individual steps. And instead what we should conclude is that tasks—like writing essays—that we humans could do, but we didn&#8217;t think computers could do, are actually in some sense computationally easier than we thought. </p>\n<p>In other words, the reason a neural net can be successful in writing an essay is because writing an essay turns out to be a &#8220;computationally shallower&#8221; problem than we thought. And in a sense this takes us closer to &#8220;having a theory&#8221; of how we humans manage to do things like writing essays, or in general deal with language. </p>\n<p>If you had a big enough neural net then, yes, you might be able to do whatever humans can readily do. But you wouldn&#8217;t capture what the natural world in general can do—or that the tools that we&#8217;ve fashioned from the natural world can do. And it&#8217;s the use of those tools—both practical and conceptual—that have allowed us in recent centuries to transcend the boundaries of what&#8217;s accessible to &#8220;pure unaided human thought&#8221;, and capture for human purposes more of what&#8217;s out there in the physical and computational universe.</p>\n<h2 id=\"the-concept-of-embeddings\">The Concept of Embeddings</h2>\n<p>Neural nets—at least as they&#8217;re currently set up—are fundamentally based on numbers. So if we&#8217;re going to to use them to work on something like text we&#8217;ll need a way to <a href=\"https://reference.wolfram.com/language/guide/NetEncoderDecoder.html\">represent our text with numbers</a>. And certainly we could start (essentially as ChatGPT does) by just assigning a number to every word in the dictionary. But there&#8217;s an important idea—that&#8217;s for example central to ChatGPT—that goes beyond that. And it&#8217;s the idea of &#8220;embeddings&#8221;. One can think of an embedding as a way to try to represent the &#8220;essence&#8221; of something by an array of numbers—with the property that &#8220;nearby things&#8221; are represented by nearby numbers.</p>\n<p>And so, for example, we can think of a word embedding as trying to <a href=\"https://reference.wolfram.com/language/ref/FeatureSpacePlot.html\">lay out words in a kind of &#8220;meaning space&#8221;</a> in which words that are somehow &#8220;nearby in meaning&#8221; appear nearby in the embedding. The actual embeddings that are used—say in ChatGPT—tend to involve large lists of numbers. But if we project down to 2D, we can show examples of how words are laid out by the embedding: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img78_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img78.png' alt='' title='' width='432' height='430'> </div>\n</p></div>\n<p>And, yes, what we see does remarkably well in capturing typical everyday impressions. But how can we construct such an embedding? Roughly the idea is to look at large amounts of text (here 5 billion words from the web) and then see &#8220;how similar&#8221; the &#8220;environments&#8221; are in which different words appear. So, for example, &#8220;alligator&#8221; and &#8220;crocodile&#8221; will often appear almost interchangeably in otherwise similar sentences, and that means they&#8217;ll be placed nearby in the embedding. But &#8220;turnip&#8221; and &#8220;eagle&#8221; won&#8217;t tend to appear in otherwise similar sentences, so they&#8217;ll be placed far apart in the embedding.</p>\n<p>But how does one actually implement something like this using neural nets? Let&#8217;s start by talking about embeddings not for words, but for images. We want to find some way to characterize images by lists of numbers in such a way that &#8220;images we consider similar&#8221; are assigned similar lists of numbers. </p>\n<p>How do we tell if we should &#8220;consider images similar&#8221;? Well, if our images are, say, of handwritten digits we might &#8220;consider two images similar&#8221; if they are of the same digit. Earlier we discussed a neural net that was trained to recognize handwritten digits. And we can think of this neural net as being set up so that in its final output it puts images into 10 different bins, one for each digit.</p>\n<p>But what if we &#8220;intercept&#8221; what&#8217;s going on inside the neural net before the final &#8220;it&#8217;s a &#8216;4&#8217;&#8221; decision is made? We might expect that inside the neural net there are numbers that characterize images as being &#8220;mostly 4-like but a bit 2-like&#8221; or some such. And the idea is to pick up such numbers to use as elements in an embedding.</p>\n<p>So here&#8217;s the concept. Rather than directly trying to characterize &#8220;what image is near what other image&#8221;, we instead consider a well-defined task (in this case digit recognition) for which we can get explicit training data—then use the fact that in doing this task the neural net implicitly has to make what amount to &#8220;nearness decisions&#8221;. So instead of us ever explicitly having to talk about &#8220;nearness of images&#8221; we&#8217;re just talking about the concrete question of what digit an image represents, and then we&#8217;re &#8220;leaving it to the neural net&#8221; to implicitly determine what that implies about &#8220;nearness of images&#8221;.</p>\n<p>So how in more detail does this work for the digit recognition network? We can think of the network as consisting of 11 successive layers, that we might summarize iconically like this (with activation functions shown as separate layers):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img79_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img79.png' alt='' title='' width='600' height='35'> </div>\n</p></div>\n<p>At the beginning we&#8217;re feeding into the first layer actual images, represented by 2D arrays of pixel values. And at the end—from the last layer—we&#8217;re getting out an array of 10 values, which we can think of saying &#8220;how certain&#8221; the network is that the image corresponds to each of the digits 0 through 9. </p>\n<p>Feed in the image <img style=\"margin-bottom: -5px\" src='https://content.wolfram.com/sites/43/2023/02/sw021423number4.png' alt='' title='' width='24' height='14'/>and the values of the neurons in that last layer are:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img81_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img81.png' alt='' title='' width='519' height='52'> </div>\n</p></div>\n<p>In other words, the neural net is by this point &#8220;incredibly certain&#8221; that this image is a 4—and to actually get the output &#8220;4&#8221; we just have to pick out the position of the neuron with the largest value.</p>\n<p>But what if we look one step earlier? The very last operation in the network is a so-called <a href=\"https://reference.wolfram.com/language/ref/SoftmaxLayer.html\">softmax</a> which tries to &#8220;force certainty&#8221;. But before that&#8217;s been applied the values of the neurons are:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img82_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img82.png' alt='' title='' width='395' height='37'> </div>\n</p></div>\n<p>The neuron representing &#8220;4&#8221; still has the highest numerical value. But there&#8217;s also information in the values of the other neurons. And we can expect that this list of numbers can in a sense be used to characterize the &#8220;essence&#8221; of the image—and thus to provide something we can use as an embedding. And so, for example, each of the 4&#8217;s here has a slightly different &#8220;signature&#8221; (or &#8220;feature embedding&#8221;)—all very different from the 8&#8217;s:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img83_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img83.png' alt='' title='' width='529' height='72'> </div>\n</p></div>\n<p>Here we&#8217;re essentially using 10 numbers to characterize our images. But it&#8217;s often better to use much more than that. And for example in our digit recognition network we can get an array of 500 numbers by tapping into the preceding layer. And this is probably a reasonable array to use as an &#8220;image embedding&#8221;. </p>\n<p>If we want to make an explicit visualization of &#8220;image space&#8221; for handwritten digits we need to &#8220;reduce the dimension&#8221;, effectively by projecting the 500-dimensional vector we&#8217;ve got into, say, 3D space:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img84_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img84.png' alt='' title='' width='326' height='354'> </div>\n</p></div>\n<p>We&#8217;ve just talked about creating a characterization (and thus embedding) for images based effectively on identifying the similarity of images by determining whether (according to our training set) they correspond to the same handwritten digit. And we can do the same thing much more generally for images if we have a training set that identifies, say, which of 5000 common types of object (cat, dog, chair, &#8230;) each image is of. And in this way we can make an image embedding that&#8217;s &#8220;anchored&#8221; by our identification of common objects, but then &#8220;generalizes around that&#8221; according to the behavior of the neural net. And the point is that insofar as that behavior aligns with how we humans perceive and interpret images, this will end up being an embedding that &#8220;seems right to us&#8221;, and is useful in practice in doing &#8220;human-judgement-like&#8221; tasks.</p>\n<p>OK, so how do we follow the same kind of approach to find embeddings for words? The key is to start from a task about words for which we can readily do training. And the standard such task is &#8220;word prediction&#8221;. Imagine we&#8217;re given &#8220;the ___ cat&#8221;. Based on a large corpus of text (say, the text content of the web), what are the probabilities for different words that might &#8220;fill in the blank&#8221;? Or, alternatively, given &#8220;___ black ___&#8221; what are the probabilities for different &#8220;flanking words&#8221;?</p>\n<p>How do we set this problem up for a neural net? Ultimately we have to formulate everything in terms of numbers. And one way to do this is just to assign a unique number to each of the 50,000 or so common words in English. So, for example, &#8220;the&#8221; might be 914, and &#8220; cat&#8221; (with a space before it) might be 3542. (And these are the actual numbers used by GPT-2.) So for the &#8220;the ___ cat&#8221; problem, our input might be {914, 3542}. What should the output be like? Well, it should be a list of 50,000 or so numbers that effectively give the probabilities for each of the possible &#8220;fill-in&#8221; words. And once again, to find an embedding, we want to &#8220;intercept&#8221; the &#8220;insides&#8221; of the neural net just before it &#8220;reaches its conclusion&#8221;—and then pick up the list of numbers that occur there, and that we can think of as &#8220;characterizing each word&#8221;.</p>\n<p>OK, so what do those characterizations look like? Over the past 10 years there&#8217;ve been a sequence of different systems developed (<a href=\"https://resources.wolframcloud.com/NeuralNetRepository/resources/ConceptNet-Numberbatch-Word-Vectors-V17.06/\">word2vec</a>, <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/search/?i=GloVe\">GloVe</a>, <a href=\"https://resources.wolframcloud.com/NeuralNetRepository/search/?i=BERT\">BERT</a>, <a href=\" https://resources.wolframcloud.com/NeuralNetRepository/resources/GPT2-Transformer-Trained-on-WebText-Data/\">GPT</a>, &#8230;), each based on a different neural net approach. But ultimately all of them take words and characterize them by lists of hundreds to thousands of numbers. </p>\n<p>In their raw form, these &#8220;embedding vectors&#8221; are quite uninformative. For example, here&#8217;s what GPT-2 produces as the raw embedding vectors for three specific words: </p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img85_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img85.png' alt='' title='' width='467' height='131'> </div>\n</p></div>\n<p>If we do things like measure distances between these vectors, then we can find things like &#8220;nearnesses&#8221; of words. Later we&#8217;ll discuss in more detail what we might consider the &#8220;cognitive&#8221; significance of such embeddings. But for now the main point is that we have a way to usefully turn words into &#8220;neural-net-friendly&#8221; collections of numbers.</p>\n<p>But actually we can go further than just characterizing words by collections of numbers; we can also do this for sequences of words, or indeed whole blocks of text. And inside ChatGPT that&#8217;s how it&#8217;s dealing with things. It takes the text it&#8217;s got so far, and generates an embedding vector to represent it. Then its goal is to find the probabilities for different words that might occur next. And it represents its answer for this as a list of numbers that essentially give the probabilities for each of the 50,000 or so possible words.</p>\n<p>(Strictly, ChatGPT does not deal with words, but <a href=\"https://platform.openai.com/tokenizer\" target=\"_blank\" rel=\"noopener\">rather with &#8220;tokens&#8221;</a>—convenient linguistic units that might be whole words, or might just be pieces like &#8220;pre&#8221; or &#8220;ing&#8221; or &#8220;ized&#8221;. Working with tokens makes it easier for ChatGPT to handle rare, compound and non-English words, and, sometimes, for better or worse, to invent new words.)</p>\n<h2 id=\"inside-chatgpt\">Inside ChatGPT</h2>\n<p>OK, so we&#8217;re finally ready to discuss what&#8217;s inside ChatGPT. And, yes, ultimately, it&#8217;s a giant neural net—currently a version of the so-called GPT-3 network with 175 billion weights. In many ways this is a neural net very much like the other ones we&#8217;ve discussed. But it&#8217;s a neural net that&#8217;s particularly set up for dealing with language. And its most notable feature is a piece of neural net architecture called a &#8220;transformer&#8221;.</p>\n<p>In the first neural nets we discussed above, every neuron at any given layer was basically connected (at least with some weight) to every neuron on the layer before. But this kind of fully connected network is (presumably) overkill if one&#8217;s working with data that has particular, known structure. And thus, for example, in the early stages of dealing with images, it&#8217;s typical to use so-called <a href=\"https://reference.wolfram.com/language/ref/ConvolutionLayer.html\">convolutional neural nets</a> (&#8220;convnets&#8221;) in which neurons are effectively laid out on a grid analogous to the pixels in the image—and connected only to neurons nearby on the grid. </p>\n<p>The idea of transformers is to do something at least somewhat similar for sequences of tokens that make up a piece of text. But instead of just defining a fixed region in the sequence over which there can be connections, transformers instead introduce the notion of &#8220;<a href=\"https://reference.wolfram.com/language/ref/AttentionLayer.html\">attention</a>&#8221;—and the idea of &#8220;paying attention&#8221; more to some parts of the sequence than others. Maybe one day it&#8217;ll make sense to just start a generic neural net and do all customization through training. But at least as of now it seems to be critical in practice to &#8220;modularize&#8221; things—as transformers do, and probably as our brains also do. </p>\n<p>OK, so what does ChatGPT (or, rather, the GPT-3 network on which it&#8217;s based) actually do? Recall that its overall goal is to continue text in a &#8220;reasonable&#8221; way, based on what it&#8217;s seen from the training it&#8217;s had (which consists in looking at billions of pages of text from the web, etc.) So at any given point, it&#8217;s got a certain amount of text—and its goal is to come up with an appropriate choice for the next token to add.</p>\n<p>It operates in three basic stages. First, it takes the sequence of tokens that corresponds to the text so far, and finds an embedding (i.e. an array of numbers) that represents these. Then it operates on this embedding—in a &#8220;standard neural net way&#8221;, with values &#8220;rippling through&#8221; successive layers in a network—to produce a new embedding (i.e. a new array of numbers). It then takes the last part of this array and generates from it an array of about 50,000 values that turn into probabilities for different possible next tokens. (And, yes, it so happens that there are about the same number of tokens used as there are common words in English, though only about 3000 of the tokens are whole words, and the rest are fragments.)</p>\n<p>A critical point is that every part of this pipeline is implemented by a neural network, whose weights are determined by end-to-end training of the network. In other words, in effect nothing except the overall architecture is &#8220;explicitly engineered&#8221;; everything is just &#8220;learned&#8221; from training data.</p>\n<p>There are, however, plenty of details in the way the architecture is set up—reflecting all sorts of experience and neural net lore. And—even though this is definitely going into the weeds—I think it&#8217;s useful to talk about some of those details, not least to get a sense of just what goes into building something like ChatGPT.</p>\n<p>First comes the embedding module. Here&#8217;s a schematic Wolfram Language representation for it for GPT-2:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img86_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img86.png' alt='' title='' width='424' height='217'> </div>\n</p></div>\n<p>The input is a <a href=\"https://reference.wolfram.com/language/ref/netencoder/SubwordTokens.html\">vector of <em>n</em> tokens</a> (represented as in the previous section by integers from 1 to about 50,000). Each of these tokens is converted (by a <a href=\"https://reference.wolfram.com/language/ref/EmbeddingLayer.html\">single-layer neural net</a>) into an embedding vector (of length 768 for GPT-2 and 12,288 for ChatGPT&#8217;s GPT-3). Meanwhile, there&#8217;s a &#8220;secondary pathway&#8221; that takes the <a href=\"https://reference.wolfram.com/language/ref/SequenceIndicesLayer.html\">sequence of (integer) positions</a> for the tokens, and from these integers creates another embedding vector. And finally the embedding vectors from the token value and the token position are <a href=\"https://reference.wolfram.com/language/ref/ThreadingLayer.html\">added together</a>—to produce the final sequence of embedding vectors from the embedding module.</p>\n<p>Why does one just add the token-value and token-position embedding vectors together? I don&#8217;t think there&#8217;s any particular science to this. It&#8217;s just that various different things have been tried, and this is one that seems to work. And it&#8217;s part of the lore of neural nets that—in some sense—so long as the setup one has is &#8220;roughly right&#8221; it&#8217;s usually possible to home in on details just by doing sufficient training, without ever really needing to &#8220;understand at an engineering level&#8221; quite how the neural net has ended up configuring itself.</p>\n<p>Here&#8217;s what the embedding module does, operating on the string <em>hello hello hello hello hello hello hello hello hello hello bye bye bye bye bye bye bye bye bye bye</em>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img87_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img87.png' alt='' title='' width='373' height='158'> </div>\n</p></div>\n<p>The elements of the embedding vector for each token are shown down the page, and across the page we see first a run of &#8220;<em>hello</em>&#8221; embeddings, followed by a run of &#8220;<em>bye</em>&#8221; ones. The second array above is the positional embedding—with its somewhat-random-looking structure being just what &#8220;happened to be learned&#8221; (in this case in GPT-2).</p>\n<p>OK, so after the embedding module comes the &#8220;main event&#8221; of the transformer: a sequence of so-called &#8220;attention blocks&#8221; (12 for GPT-2, 96 for ChatGPT&#8217;s GPT-3). It&#8217;s all pretty complicated—and reminiscent of typical large hard-to-understand engineering systems, or, for that matter, biological systems. But anyway, here&#8217;s a schematic representation of a single &#8220;attention block&#8221; (for GPT-2):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img88_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img88.png' alt='' title='' width='654' height='193'> </div>\n</p></div>\n<p>Within each such attention block there are a collection of &#8220;attention heads&#8221; (12 for GPT-2, 96 for ChatGPT&#8217;s GPT-3)—each of which operates independently on different chunks of values in the embedding vector. (And, yes, we don&#8217;t know any particular reason why it&#8217;s a good idea to split up the embedding vector, or what the different parts of it &#8220;mean&#8221;; this is just one of those things that&#8217;s been &#8220;found to work&#8221;.) </p>\n<p>OK, so what do the attention heads do? Basically they&#8217;re a way of &#8220;looking back&#8221; in the sequence of tokens (i.e. in the text produced so far), and &#8220;packaging up the past&#8221; in a form that&#8217;s useful for finding the next token. <a target=\"_self\" href=\"https://writings.stephenwolfram.com/2023/02/what-is-chatgpt-doing-and-why-does-it-work/#its-just-adding-one-word-at-a-time\">In the first section above</a> we talked about using 2-gram probabilities to pick words based on their immediate predecessors. What the &#8220;attention&#8221; mechanism in transformers does is to allow &#8220;attention to&#8221; even much earlier words—thus potentially capturing the way, say, verbs can refer to nouns that appear many words before them in a sentence.</p>\n<p>At a more detailed level, what an attention head does is to recombine chunks in the embedding vectors associated with different tokens, with certain weights. And so, for example, the 12 attention heads in the first attention block (in GPT-2) have the following (&#8220;look-back-all-the-way-to-the-beginning-of-the-sequence-of-tokens&#8221;) patterns of &#8220;recombination weights&#8221; for the &#8220;<em>hello</em>, <em>bye</em>&#8221; string above:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img89_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img89A.png' alt='' title='' width='550' height=''> </div>\n</p></div>\n<p>After being processed by the attention heads, the resulting &#8220;re-weighted embedding vector&#8221; (of length 768 for GPT-2 and length 12,288 for ChatGPT&#8217;s GPT-3) is passed through a standard <a href=\"https://reference.wolfram.com/language/ref/LinearLayer.html\">&#8220;fully connected&#8221; neural net layer</a>.

Ultimately it&#8217;s presumably some &#8220;neural net encoding&#8221; of features of human language. But as of now, what those features might be is quite unknown. In effect, we&#8217;re &#8220;opening up the brain of ChatGPT&#8221; (or at least GPT-2) and discovering, yes, it&#8217;s complicated in there, and we don&#8217;t understand it—even though in the end it&#8217;s producing recognizable human language.</p>\n<p>OK, so after going through one attention block, we&#8217;ve got a new embedding vector—which is then successively passed through additional attention blocks (a total of 12 for GPT-2; 96 for GPT-3). Each attention block has its own particular pattern of &#8220;attention&#8221; and &#8220;fully connected&#8221; weights. Here for GPT-2 are the sequence of attention weights for the &#8220;hello, bye&#8221; input, for the first attention head:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img92_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img92A.png' alt='' title='' width='512' height=''> </div>\n</p></div>\n<p>And here are the (moving-averaged) &#8220;matrices&#8221; for the fully connected layers:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img93_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img93A.png' alt='' title='' width='569' height='422'> </div>\n</p></div>\n<p>Curiously, even though these &#8220;matrices of weights&#8221; in different attention blocks look quite similar, the distributions of the sizes of weights can be somewhat different (and are not always Gaussian):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img94_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img94A.png' alt='' title='' width='351' height=''> </div>\n</p></div>\n<p>So after going through all these attention blocks what is the net effect of the transformer? Essentially it&#8217;s to transform the original collection of embeddings for the sequence of tokens to a final collection. And the particular way ChatGPT works is then to pick up the last embedding in this collection, and &#8220;decode&#8221; it to produce a list of probabilities for what token should come next.</p>\n<p>So that&#8217;s in outline what&#8217;s inside ChatGPT. It may seem complicated (not least because of its many inevitably somewhat arbitrary &#8220;engineering choices&#8221;), but actually the ultimate elements involved are remarkably simple. Because in the end what we&#8217;re dealing with is just a neural net made of &#8220;artificial neurons&#8221;, each doing the simple operation of taking a collection of numerical inputs, and then combining them with certain weights. </p>\n<p>The original input to ChatGPT is an array of numbers (the embedding vectors for the tokens so far), and what happens when ChatGPT &#8220;runs&#8221; to produce a new token is just that these numbers &#8220;ripple through&#8221; the layers of the neural net, with each neuron &#8220;doing its thing&#8221; and passing the result to neurons on the next layer. There&#8217;s no looping or &#8220;going back&#8221;. Everything just &#8220;feeds forward&#8221; through the network. </p>\n<p>It&#8217;s a very different setup from a typical computational system—like a <a href=\"https://www.wolframscience.com/nks/chap-3--the-world-of-simple-\\ programs/#sect-3-4--turing-machines\">Turing machine</a>—in which results are repeatedly &#8220;reprocessed&#8221; by the same computational elements. Here—at least in generating a given token of output—each computational element (i.e. neuron) is used only once. </p>\n<p>But there is in a sense still an &#8220;outer loop&#8221; that reuses computational elements even in ChatGPT. Because when ChatGPT is going to generate a new token, it always &#8220;reads&#8221; (i.e. takes as input) the whole sequence of tokens that come before it, including tokens that ChatGPT itself has &#8220;written&#8221; previously. And we can think of this setup as meaning that ChatGPT does—at least at its outermost level—involve a &#8220;feedback loop&#8221;, albeit one in which every iteration is explicitly visible as a token that appears in the text that it generates.</p>\n<p>But let&#8217;s come back to the core of ChatGPT: the neural net that&#8217;s being repeatedly used to generate each token. At some level it&#8217;s very simple: a whole collection of identical artificial neurons. And some parts of the network just consist of (&#8220;<a href=\"https://reference.wolfram.com/language/ref/LinearLayer.html\">fully connected</a>&#8221;) layers of neurons in which every neuron on a given layer is connected (with some weight) to every neuron on the layer before. But particularly with its transformer architecture, ChatGPT has parts with more structure, in which only specific neurons on different layers are connected. (Of course, one could still say that &#8220;all neurons are connected&#8221;—but some just have zero weight.)</p>\n<p>In addition, there are aspects of the neural net in ChatGPT that aren&#8217;t most naturally thought of as just consisting of &#8220;homogeneous&#8221; layers. And for example—as the iconic summary above indicates—inside an attention block there are places where &#8220;multiple copies are made&#8221; of incoming data, each then going through a different &#8220;processing path&#8221;, potentially involving a different number of layers, and only later recombining. But while this may be a convenient representation of what&#8217;s going on, it&#8217;s always at least in principle possible to think of &#8220;densely filling in&#8221; layers, but just having some weights be zero.</p>\n<p>If one looks at the longest path through ChatGPT, there are about 400 (core) layers involved—in some ways not a huge number. But there are millions of neurons—with a total of 175 billion connections and therefore 175 billion weights. And one thing to realize is that every time ChatGPT generates a new token, it has to do a calculation involving every single one of these weights. Implementationally these calculations can be somewhat organized &#8220;by layer&#8221; into highly parallel array operations that can conveniently be done on GPUs. But for each token that&#8217;s produced, there still have to be 175 billion calculations done (and in the end a bit more)—so that, yes, it&#8217;s not surprising that it can take a while to generate a long piece of text with ChatGPT. </p>\n<p>But in the end, the remarkable thing is that all these operations—individually as simple as they are—can somehow together manage to do such a good &#8220;human-like&#8221; job of generating text. It has to be emphasized again that (at least so far as we know) there&#8217;s no &#8220;ultimate theoretical reason&#8221; why anything like this should work. And in fact, as we&#8217;ll discuss, I think we have to view this as a—potentially surprising—scientific discovery: that somehow in a neural net like ChatGPT&#8217;s it&#8217;s possible to capture the essence of what human brains manage to do in generating language. </p>\n<h2 id=\"the-training-of-chatgpt\">The Training of ChatGPT</h2>\n<p>OK, so we&#8217;ve now given an outline of how ChatGPT works once it&#8217;s set up. But how did it get set up? How were all those 175 billion weights in its neural net determined? Basically they&#8217;re the result of very large-scale training, based on a huge corpus of text—on the web, in books, etc.—written by humans. As we&#8217;ve said, even given all that training data, it&#8217;s certainly not obvious that a neural net would be able to successfully produce &#8220;human-like&#8221; text. And, once again, there seem to be detailed pieces of engineering needed to make that happen. But the big surprise—and discovery—of ChatGPT is that it&#8217;s possible at all. And that—in effect—a neural net with &#8220;just&#8221; 175 billion weights can make a &#8220;reasonable model&#8221; of text humans write.</p>\n<p>In modern times, there&#8217;s lots of text written by humans that&#8217;s out there in digital form. The public web has at least several billion human-written pages, with altogether perhaps a trillion words of text. And if one includes non-public webpages, the numbers might be at least 100 times larger. So far, more than 5 million digitized books have been made available (out of 100 million or so that have ever been published), giving another 100 billion or so words of text. And that&#8217;s not even mentioning text derived from speech in videos, etc. (As a personal comparison, <a href=\"https://www.stephenwolfram.com/publications/\">my total lifetime output of published material</a> has been a bit under 3 million words, and over the <a href=\"https://writings.stephenwolfram.com/2012/03/the-personal-analytics-of-my-life/\">past 30 years I&#8217;ve written</a> about 15 million words of email, and altogether typed perhaps 50 million words—and in just the past couple of years I&#8217;ve spoken more than 10 million words on <a href=\"https://www.stephenwolfram.com/livestreams\">livestreams</a>. And, yes, I&#8217;ll train a bot from all of that.)</p>\n<p>But, OK, given all this data, how does one train a neural net from it? The basic process is very much as we discussed it in the simple examples above. You present a batch of examples, and then you adjust the weights in the network to minimize the error (&#8220;loss&#8221;) that the network makes on those examples. The main thing that&#8217;s expensive about &#8220;back propagating&#8221; from the error is that each time you do this, every weight in the network will typically change at least a tiny bit, and there are just a lot of weights to deal with. (The actual &#8220;back computation&#8221; is typically only a small constant factor harder than the forward one.)</p>\n<p>With modern GPU hardware, it&#8217;s straightforward to compute the results from batches of thousands of examples in parallel. But when it comes to actually updating the weights in the neural net, current methods require one to do this basically batch by batch. (And, yes, this is probably where actual brains—with their combined computation and memory elements—have, for now, at least an architectural advantage.)</p>\n<p>Even in the seemingly simple cases of learning numerical functions that we discussed earlier, we found we often had to use millions of examples to successfully train a network, at least from scratch. So how many examples does this mean we&#8217;ll need in order to train a &#8220;human-like language&#8221; model? There doesn&#8217;t seem to be any fundamental &#8220;theoretical&#8221; way to know. But in practice ChatGPT was successfully trained on a few hundred billion words of text.</p>\n<p>Some of the text it was fed several times, some of it only once. But somehow it &#8220;got what it needed&#8221; from the text it saw. But given this volume of text to learn from, how large a network should it require to &#8220;learn it well&#8221;? Again, we don&#8217;t yet have a fundamental theoretical way to say. Ultimately—as we&#8217;ll discuss further below—there&#8217;s presumably a certain &#8220;total algorithmic content&#8221; to human language and what humans typically say with it. But the next question is how efficient a neural net will be at implementing a model based on that algorithmic content. And again we don&#8217;t know—although the success of ChatGPT suggests it&#8217;s reasonably efficient.</p>\n<p>And in the end we can just note that ChatGPT does what it does using a couple hundred billion weights—comparable in number to the total number of words (or tokens) of training data it&#8217;s been given. In some ways it&#8217;s perhaps surprising (though empirically observed also in smaller analogs of ChatGPT) that the &#8220;size of the network&#8221; that seems to work well is so comparable to the &#8220;size of the training data&#8221;. After all, it&#8217;s certainly not that somehow &#8220;inside ChatGPT&#8221; all that text from the web and books and so on is &#8220;directly stored&#8221;. Because what&#8217;s actually inside ChatGPT are a bunch of numbers—with a bit less than 10 digits of precision—that are some kind of distributed encoding of the aggregate structure of all that text. </p>\n<p>Put another way, we might ask what the &#8220;effective information content&#8221; is of human language and what&#8217;s typically said with it. There&#8217;s the raw corpus of examples of language. And then there&#8217;s the representation in the neural net of ChatGPT. That representation is very likely far from the &#8220;algorithmically minimal&#8221; representation (as we&#8217;ll discuss below). But it&#8217;s a representation that&#8217;s readily usable by the neural net. And in this representation it seems there&#8217;s in the end rather little &#8220;compression&#8221; of the training data; it seems on average to basically take only a bit less than one neural net weight to carry the &#8220;information content&#8221; of a word of training data.</p>\n<p>When we run ChatGPT to generate text, we&#8217;re basically having to use each weight once. So if there are <em>n</em> weights, we&#8217;ve got of order <em>n</em> computational steps to do—though in practice many of them can typically be done in parallel in GPUs. But if we need about <em>n</em> words of training data to set up those weights, then from what we&#8217;ve said above we can conclude that we&#8217;ll need about <em>n</em><sup>2</sup> computational steps to do the training of the network—which is why, with current methods, one ends up needing to talk about billion-dollar training efforts.</p>\n<h2 id=\"beyond-basic-training\">Beyond Basic Training</h2>\n<p>The majority of the effort in training ChatGPT is spent &#8220;showing it&#8221; large amounts of existing text from the web, books, etc. But it turns out there&#8217;s another—apparently rather important—part too. </p>\n<p>As soon as it&#8217;s finished its &#8220;raw training&#8221; from the original corpus of text it&#8217;s been shown, the neural net inside ChatGPT is ready to start generating its own text, continuing from prompts, etc. But while the results from this may often seem reasonable, they tend—particularly for longer pieces of text—to &#8220;wander off&#8221; in often rather non-human-like ways. It&#8217;s not something one can readily detect, say, by doing traditional statistics on the text. But it&#8217;s something that actual humans reading the text easily notice.</p>\n<p>And a <a href=\"https://openai.com/blog/instruction-following/\" target=\"_blank\" rel=\"noopener\">key idea in the construction of ChatGPT</a> was to have another step after &#8220;passively reading&#8221; things like the web: to have actual humans actively interact with ChatGPT, see what it produces, and in effect give it feedback on &#8220;how to be a good chatbot&#8221;. But how can the neural net use that feedback? The first step is just to have humans rate results from the neural net. But then another neural net model is built that attempts to predict those ratings. But now this prediction model can be run—essentially like a loss function—on the original network, in effect allowing that network to be &#8220;tuned up&#8221; by the human feedback that&#8217;s been given. And the results in practice seem to have a big effect on the success of the system in producing &#8220;human-like&#8221; output. </p>\n<p>In general, it&#8217;s interesting how little &#8220;poking&#8221; the &#8220;originally trained&#8221; network seems to need to get it to usefully go in particular directions. One might have thought that to have the network behave as if it&#8217;s &#8220;learned something new&#8221; one would have to go in and run a training algorithm, adjusting weights, and so on.</p>\n<p>But that&#8217;s not the case. Instead, it seems to be sufficient to basically tell ChatGPT something one time—as part of the prompt you give—and then it can successfully make use of what you told it when it generates text. And once again, the fact that this works is, I think, an important clue in understanding what ChatGPT is &#8220;really doing&#8221; and how it relates to the structure of human language and thinking. </p>\n<p>There&#8217;s certainly something rather human-like about it: that at least once it&#8217;s had all that pre-training you can tell it something just once and it can &#8220;remember it&#8221;—at least &#8220;long enough&#8221; to generate a piece of text using it. So what&#8217;s going on in a case like this? It could be that &#8220;everything you might tell it is already in there somewhere&#8221;—and you&#8217;re just leading it to the right spot. But that doesn&#8217;t seem plausible. Instead, what seems more likely is that, yes, the elements are already in there, but the specifics are defined by something like a &#8220;trajectory between those elements&#8221; and that&#8217;s what you&#8217;re introducing when you tell it something.</p>\n<p>And indeed, much like for humans, if you tell it something bizarre and unexpected that completely doesn&#8217;t fit into the framework it knows, it doesn&#8217;t seem like it&#8217;ll successfully be able to &#8220;integrate&#8221; this. It can &#8220;integrate&#8221; it only if it&#8217;s basically riding in a fairly simple way on top of the framework it already has.</p>\n<p>It&#8217;s also worth pointing out again that there are inevitably &#8220;algorithmic limits&#8221; to what the neural net can &#8220;pick up&#8221;. Tell it &#8220;shallow&#8221; rules of the form &#8220;this goes to that&#8221;, etc., and the neural net will most likely be able to represent and reproduce these just fine—and indeed what it &#8220;already knows&#8221; from language will give it an immediate pattern to follow. But try to give it rules for an actual &#8220;deep&#8221; computation that involves many potentially computationally irreducible steps and it just won&#8217;t work. (Remember that at each step it&#8217;s always just &#8220;feeding data forward&#8221; in its network, never looping except by virtue of generating new tokens.)</p>\n<p>Of course, the network can learn the answer to specific &#8220;irreducible&#8221; computations. But as soon as there are combinatorial numbers of possibilities, no such &#8220;table-lookup-style&#8221; approach will work. And so, yes, just like humans, it&#8217;s time then for neural nets to &#8220;reach out&#8221; and use actual computational tools. (And, yes, <a href=\"https://www.wolframalpha.com/\">Wolfram|Alpha</a> and <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a> are <a href=\"https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/\">uniquely suitable</a>, because they&#8217;ve been built to &#8220;talk about things in the world&#8221;, just like the language-model neural nets.)</p>\n<h2 id=\"what-really-lets-chatgpt-work?\">What Really Lets ChatGPT Work?</h2>\n<p>Human language—and the processes of thinking involved in generating it—have always seemed to represent a kind of pinnacle of complexity. And indeed it&#8217;s seemed somewhat remarkable that human brains—with their network of a &#8220;mere&#8221; 100 billion or so neurons (and maybe 100 trillion connections) could be responsible for it. Perhaps, one might have imagined, there&#8217;s something more to brains than their networks of neurons—like some new layer of undiscovered physics. But now with ChatGPT we&#8217;ve got an important new piece of information: we know that a pure, artificial neural network with about as many connections as brains have neurons is capable of doing a surprisingly good job of generating human language.</p>\n<p>And, yes, that&#8217;s still a big and complicated system—with about as many neural net weights as there are words of text currently available out there in the world. But at some level it still seems difficult to believe that all the richness of language and the things it can talk about can be encapsulated in such a finite system. Part of what&#8217;s going on is no doubt a reflection of the ubiquitous phenomenon (that first became evident in the <a href=\"https://www.wolframscience.com/nks/chap-2--the-crucial-experiment#sect-2-1--how-do-simple-programs-behave\">example of rule 30</a>) that computational processes can in effect greatly amplify the apparent complexity of systems even when their underlying rules are simple. But, actually, as we discussed above, neural nets of the kind used in ChatGPT tend to be specifically constructed to restrict the effect of this phenomenon—and the computational irreducibility associated with it—in the interest of making their training more accessible.</p>\n<p>So how is it, then, that something like ChatGPT can get as far as it does with language? The basic answer, I think, is that language is at a fundamental level somehow simpler than it seems. And this means that ChatGPT—even with its ultimately straightforward neural net structure—is successfully able to &#8220;capture the essence&#8221; of human language and the thinking behind it. And moreover, in its training, ChatGPT has somehow &#8220;implicitly discovered&#8221; whatever regularities in language (and thinking) make this possible.</p>\n<p>The success of ChatGPT is, I think, giving us evidence of a fundamental and important piece of science: it&#8217;s suggesting that we can expect there to be major new &#8220;laws of language&#8221;—and effectively &#8220;laws of thought&#8221;—out there to discover. In ChatGPT—built as it is as a neural net—those laws are at best implicit. But if we could somehow make the laws explicit, there&#8217;s the potential to do the kinds of things ChatGPT does in vastly more direct, efficient—and transparent—ways.</p>\n<p>But, OK, so what might these laws be like? Ultimately they must give us some kind of prescription for how language—and the things we say with it—are put together. Later we&#8217;ll discuss how &#8220;looking inside ChatGPT&#8221; may be able to give us some hints about this, and how what we know from building computational language suggests a path forward. But first let&#8217;s discuss two long-known examples of what amount to &#8220;laws of language&#8221;—and how they relate to the operation of ChatGPT.</p>\n<p>The first is the syntax of language. Language is not just a random jumble of words. Instead, there are (fairly) definite <a href=\"https://www.wolframscience.com/nks/notes-10-12--computer-and-human-languages/\">grammatical rules</a> for how words of different kinds can be put together: in English, for example, nouns can be preceded by adjectives and followed by verbs, but typically two nouns can&#8217;t be right next to each other. Such grammatical structure can (at least approximately) be captured by a set of rules that define how what amount to <a href=\"https://reference.wolfram.com/language/ref/TextStructure.html\">&#8220;parse trees&#8221; can be put together</a>:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img96_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img96.png' alt='' title='' width='613' height='262'> </div>\n</p></div>\n<p>ChatGPT doesn&#8217;t have any explicit &#8220;knowledge&#8221; of such rules.

But to get some insight it&#8217;s perhaps instructive to look at a much simpler example.</p>\n<p>Consider a &#8220;language&#8221; formed from sequences of (&#8217;s and )&#8217;s, with a <a href=\"https://www.wolframscience.com/nks/notes-7-9--nested-lists/\">grammar that specifies</a> that parentheses should always be balanced, as represented by a parse tree like:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img97_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img97.png' alt='' title='' width='531' height='123'> </div>\n</p></div>\n<p>Can we train a neural net to produce &#8220;grammatically correct&#8221; parenthesis sequences?

And given a simple transformer net, we can start feeding it grammatically correct parenthesis sequences as training examples. A subtlety (which actually also appears in ChatGPT&#8217;s generation of human language) is that in addition to our &#8220;content tokens&#8221; (here &#8220;(&#8221; and &#8220;)&#8221;) we have to include an &#8220;End&#8221; token, that&#8217;s generated to indicate that the output shouldn&#8217;t continue any further (i.e. for ChatGPT, that one&#8217;s reached the &#8220;end of the story&#8221;).</p>\n<p>If we set up a transformer net with just one attention block with 8 heads and feature vectors of length 128 (ChatGPT also uses feature vectors of length 128, but has 96 attention blocks, each with 96 heads) then it doesn&#8217;t seem possible to get it to learn much about parenthesis language. But with 2 attention blocks, the learning process seems to converge—at least after 10 million or so examples have been given (and, as is common with transformer nets, showing yet more examples just seems to degrade its performance).</p>\n<p>So with this network, we can do the analog of what ChatGPT does, and ask for probabilities for what the next token should be—in a parenthesis sequence:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img98_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img98.png' alt='' title='' width='503' height='83'> </div>\n</p></div>\n<p>And in the first case, the network is &#8220;pretty sure&#8221; that the sequence can&#8217;t end here—which is good, because if it did, the parentheses would be left unbalanced. In the second case, however, it &#8220;correctly recognizes&#8221; that the sequence can end here, though it also &#8220;points out&#8221; that it&#8217;s possible to &#8220;start again&#8221;, putting down a &#8220;(&#8221;, presumably with a &#8220;)&#8221; to follow. But, oops, even with its 400,000 or so laboriously trained weights, it says there&#8217;s a 15% probability to have &#8220;)&#8221; as the next token—which isn&#8217;t right, because that would necessarily lead to an unbalanced parenthesis.</p>\n<p>Here&#8217;s what we get if we ask the network for the highest-probability completions for progressively longer sequences of (&#8217;s:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img99_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img99A.png' alt='' title='' width='341' height=''> </div>\n</p></div>\n<p>And, yes, up to a certain length the network does just fine. But then it starts failing. It&#8217;s a pretty typical kind of thing to see in a &#8220;precise&#8221; situation like this with a neural net (or with machine learning in general). Cases that a human &#8220;can solve in a glance&#8221; the neural net can solve too. But cases that require doing something &#8220;more algorithmic&#8221; (e.g. explicitly counting parentheses to see if they&#8217;re closed) the neural net tends to somehow be &#8220;too computationally shallow&#8221; to reliably do. (By the way, even the full current ChatGPT has a hard time correctly matching parentheses in long sequences.)</p>\n<p>So what does this mean for things like ChatGPT and the syntax of a language like English? The parenthesis language is &#8220;austere&#8221;—and much more of an &#8220;algorithmic story&#8221;. But in English it&#8217;s much more realistic to be able to &#8220;guess&#8221; what&#8217;s grammatically going to fit on the basis of local choices of words and other hints. And, yes, the neural net is much better at this—even though perhaps it might miss some &#8220;formally correct&#8221; case that, well, humans might miss as well. But the main point is that the fact that there&#8217;s an overall syntactic structure to the language—with all the regularity that implies—in a sense limits &#8220;how much&#8221; the neural net has to learn. And a key &#8220;natural-science-like&#8221; observation is that the transformer architecture of neural nets like the one in ChatGPT seems to successfully be able to learn the kind of nested-tree-like syntactic structure that seems to exist (at least in some approximation) in all human languages.</p>\n<p>Syntax provides one kind of constraint on language. But there are clearly more. A sentence like &#8220;Inquisitive electrons eat blue theories for fish&#8221; is grammatically correct but isn&#8217;t something one would normally expect to say, and wouldn&#8217;t be considered a success if ChatGPT generated it—because, well, with the normal meanings for the words in it, it&#8217;s basically meaningless. </p>\n<p>But is there a general way to tell if a sentence is meaningful? There&#8217;s no traditional overall theory for that. But it&#8217;s something that one can think of ChatGPT as having implicitly &#8220;developed a theory for&#8221; after being trained with billions of (presumably meaningful) sentences from the web, etc. </p>\n<p>What might this theory be like? Well, there&#8217;s one tiny corner that&#8217;s basically been known for two millennia, and that&#8217;s <a href=\"https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/\">logic</a>. And certainly in the syllogistic form in which Aristotle discovered it, logic is basically a way of saying that sentences that follow certain patterns are reasonable, while others are not. Thus, for example, it&#8217;s reasonable to say &#8220;All X are Y. This is not Y, so it&#8217;s not an X&#8221; (as in &#8220;All fishes are blue. This is not blue, so it&#8217;s not a fish.&#8221;). And just as one can somewhat whimsically imagine that Aristotle discovered syllogistic logic by going (&#8220;machine-learning-style&#8221;) through lots of examples of rhetoric, so too one can imagine that in the training of ChatGPT it will have been able to &#8220;discover syllogistic logic&#8221; by looking at lots of text on the web, etc. (And, yes, while one can therefore expect ChatGPT to produce text that contains &#8220;correct inferences&#8221; based on things like syllogistic logic, it&#8217;s a quite different story when it comes to more sophisticated formal logic—and I think one can expect it to fail here for the same kind of reasons it fails in parenthesis matching.)</p>\n<p>But beyond the narrow example of logic, what can be said about how to systematically construct (or recognize) even plausibly meaningful text? Yes, there are things like <a href=\"https://en.wikipedia.org/wiki/Mad_Libs\" target=\"_blank\" rel=\"noopener\">Mad Libs</a> that use very specific &#8220;phrasal templates&#8221;. But somehow ChatGPT implicitly has a much more general way to do it. And perhaps there&#8217;s nothing to be said about how it can be done beyond &#8220;somehow it happens when you have 175 billion neural net weights&#8221;. But I strongly suspect that there&#8217;s a much simpler and stronger story.</p>\n<h2 id=\"meaning-space-and-semantic-laws-of-motion\">Meaning Space and Semantic Laws of Motion</h2>\n<p>We discussed above that inside ChatGPT any piece of text is effectively represented by an array of numbers that we can think of as coordinates of a point in some kind of &#8220;linguistic feature space&#8221;. So when ChatGPT continues a piece of text this corresponds to tracing out a trajectory in linguistic feature space. But now we can ask what makes this trajectory correspond to text we consider meaningful. And might there perhaps be some kind of &#8220;semantic laws of motion&#8221; that define—or at least constrain—how points in linguistic feature space can move around while preserving &#8220;meaningfulness&#8221;?</p>\n<p>So what is this linguistic feature space like? Here&#8217;s an example of how single words (here, common nouns) might get laid out if we project such a feature space down to 2D:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img100_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img100.png' alt='' title='' width='558' height='524'> </div>\n</p></div>\n<p>We saw another example above based on words representing plants and animals. But the point in both cases is that &#8220;semantically similar words&#8221; are placed nearby.</p>\n<p>As another example, here&#8217;s how words corresponding to different parts of speech get laid out:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img101_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img101-edit.png' alt='' title='' width='575' height=''> </div>\n</p></div>\n<p>Of course, a given word doesn&#8217;t in general just have &#8220;one meaning&#8221; (or necessarily correspond to just one part of speech). And by looking at how sentences containing a word lay out in feature space, one can often &#8220;tease apart&#8221; different meanings—as in the example here for the word &#8220;crane&#8221; (bird or machine?):</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img102_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img102.png' alt='' title='' width='593' height='364'> </div>\n</p></div>\n<p>OK, so it&#8217;s at least plausible that we can think of this feature space as placing &#8220;words nearby in meaning&#8221; close in this space. But what kind of additional structure can we identify in this space? Is there for example some kind of notion of &#8220;parallel transport&#8221; that would reflect &#8220;flatness&#8221; in the space? One way to get a handle on that is to look at analogies:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img103_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img103.png' alt='' title='' width='552' height='279'> </div>\n</p></div>\n<p>And, yes, even when we project down to 2D, there&#8217;s often at least a &#8220;hint of flatness&#8221;, though it&#8217;s certainly not universally seen.</p>\n<p>So what about trajectories? We can look at the trajectory that a prompt for ChatGPT follows in feature space—and then we can see how ChatGPT continues that:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img104_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img104.png' alt='' title='' width='549' height='339'> </div>\n</p></div>\n<p>There&#8217;s certainly no &#8220;geometrically obvious&#8221; law of motion here. And that&#8217;s not at all surprising; we fully expect this to be a <a href=\"https://writings.stephenwolfram.com/2021/09/multicomputation-a-fourth-paradigm-for-theoretical-science/#linguistics\">considerably more complicated story</a>. And, for example, it&#8217;s far from obvious that even if there is a &#8220;semantic law of motion&#8221; to be found, what kind of embedding (or, in effect, what &#8220;variables&#8221;) it&#8217;ll most naturally be stated in. </p>\n<p>In the picture above, we&#8217;re showing several steps in the &#8220;trajectory&#8221;—where at each step we&#8217;re picking the word that ChatGPT considers the most probable (the &#8220;zero temperature&#8221; case). But we can also ask what words can &#8220;come next&#8221; with what probabilities at a given point:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img105_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img105.png' alt='' title='' width='359' height='227'> </div>\n</p></div>\n<p>And what we see in this case is that there&#8217;s a &#8220;fan&#8221; of high-probability words that seems to go in a more or less definite direction in feature space. What happens if we go further? Here are the successive &#8220;fans&#8221; that appear as we &#8220;move along&#8221; the trajectory:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img106_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img106.png' alt='' title='' width='578' height='566'> </div>\n</p></div>\n<p>Here&#8217;s a 3D representation, going for a total of 40 steps:</p>\n<div>\n<div class='wolfram-c2c-wrapper writtings-c2c_above' data-c2c-file='https://content.wolfram.com/sites/43/2023/02/sw021423img107_copy.txt' data-c2c-type='text/html'> <img loading='lazy' src='https://content.wolfram.com/sites/43/2023/02/sw021423img107.png' alt='' title='' width='359' height='294'> </div>\n</p></div>\n<p>And, yes, this seems like a mess—and doesn&#8217;t do anything to particularly encourage the idea that one can expect to identify &#8220;mathematical-physics-like&#8221; &#8220;semantic laws of motion&#8221; by empirically studying &#8220;what ChatGPT is doing inside&#8221;. But perhaps we&#8217;re just looking at the &#8220;wrong variables&#8221; (or wrong coordinate system) and if only we looked at the right one, we&#8217;d immediately see that ChatGPT is doing something &#8220;mathematical-physics-simple&#8221; like following geodesics. But as of now, we&#8217;re not ready to &#8220;empirically decode&#8221; from its &#8220;internal behavior&#8221; what ChatGPT has &#8220;discovered&#8221; about how human language is &#8220;put together&#8221;. </p>\n<h2 id=\"semantic-grammar-and-the-power-of-computational-language\">Semantic Grammar and the Power of Computational Language</h2>\n<p>What does it take to produce &#8220;meaningful human language&#8221;? In the past, we might have assumed it could be nothing short of a human brain. But now we know it can be done quite respectably by the neural net of ChatGPT. Still, maybe that&#8217;s as far as we can go, and there&#8217;ll be nothing simpler—or more human understandable—that will work. But my strong suspicion is that the success of ChatGPT implicitly reveals an important &#8220;scientific&#8221; fact: that there&#8217;s actually a lot more structure and simplicity to meaningful human language than we ever knew—and that in the end there may be even fairly simple rules that describe how such language can be put together.</p>\n<p>As we mentioned above, syntactic grammar gives rules for how words corresponding to things like different parts of speech can be put together in human language. But to deal with meaning, we need to go further. And one version of how to do this is to think about not just a syntactic grammar for language, but also a semantic one. </p>\n<p>For purposes of syntax, we identify things like nouns and verbs. But for purposes of semantics, we need &#8220;finer gradations&#8221;. So, for example, we might identify the concept of &#8220;moving&#8221;, and the concept of an &#8220;object&#8221; that &#8220;maintains its identity independent of location&#8221;. There are endless specific examples of each of these &#8220;semantic concepts&#8221;. But for the purposes of our semantic grammar, we&#8217;ll just have some general kind of rule that basically says that &#8220;objects&#8221; can &#8220;move&#8221;. There&#8217;s a lot to say about how all this might work (<a href=\"https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/\">some of which I&#8217;ve said before</a>). But I&#8217;ll content myself here with just a few remarks that indicate some of the potential path forward.</p>\n<p>It&#8217;s worth mentioning that even if a sentence is perfectly OK according to the semantic grammar, that doesn&#8217;t mean it&#8217;s been realized (or even could be realized) in practice. &#8220;The elephant traveled to the Moon&#8221; would doubtless &#8220;pass&#8221; our semantic grammar, but it certainly hasn&#8217;t been realized (at least yet) in our actual world—though it&#8217;s absolutely fair game for a fictional world.</p>\n<p>When we start talking about &#8220;semantic grammar&#8221; we&#8217;re soon led to ask &#8220;What&#8217;s underneath it?&#8221; What &#8220;model of the world&#8221; is it assuming? A syntactic grammar is really just about the construction of language from words. But a semantic grammar necessarily engages with some kind of &#8220;model of the world&#8221;—something that serves as a &#8220;skeleton&#8221; on top of which language made from actual words can be layered.</p>\n<p>Until recent times, we might have imagined that (human) language would be the only general way to describe our &#8220;model of the world&#8221;. Already a few centuries ago there started to be formalizations of specific kinds of things, based particularly on mathematics. But now there&#8217;s a much more general approach to formalization: <a href=\"https://writings.stephenwolfram.com/2019/05/what-weve-built-is-a-computational-language-and-thats-very-important/\">computational language</a>.</p>\n<p>And, yes, that&#8217;s been my big project over the course of more than four decades (as now embodied in the <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>): to develop a precise symbolic representation that can talk as broadly as possible about things in the world, as well as abstract things that we care about. And so, for example, we have symbolic representations for <a href=\"https://reference.wolfram.com/language/ref/entity/City.html\">cities</a> and <a href=\"https://reference.wolfram.com/language/guide/MolecularStructureAndComputation.html\">molecules</a> and <a href=\"https://reference.wolfram.com/language/guide/ImageRepresentation.html\">images</a> and <a href=\"https://reference.wolfram.com/language/guide/NeuralNetworkConstruction.html\">neural networks</a>, and we have built-in knowledge about how to compute about those things. </p>\n<p>And, after decades of work, we&#8217;ve covered a lot of areas in this way. But in the past, we haven&#8217;t particularly dealt with &#8220;<a href=\"https://writings.stephenwolfram.com/2016/10/computational-law-symbolic-discourse-and-the-ai-constitution/\">everyday discourse</a>&#8221;. In &#8220;I bought two pounds of apples&#8221; we can <a href=\"https://reference.wolfram.com/language/ref/entity/Food.html\">readily represent</a> (and do nutrition and other computations on) the &#8220;two pounds of apples&#8221;. But we don&#8217;t (quite yet) have a symbolic representation for &#8220;I bought&#8221;.</p>\n<p>It&#8217;s all connected to the idea of semantic grammar—and the goal of having a generic symbolic &#8220;construction kit&#8221; for concepts, that would give us rules for what could fit together with what, and thus for the &#8220;flow&#8221; of what we might turn into human language. </p>\n<p>But let&#8217;s say we had this &#8220;symbolic discourse language&#8221;. What would we do with it? We could start off doing things like generating &#8220;locally meaningful text&#8221;. But ultimately we&#8217;re likely to want more &#8220;globally meaningful&#8221; results—which means &#8220;computing&#8221; more about what can actually exist or happen in the world (or perhaps in some consistent fictional world). </p>\n<p>Right now in Wolfram Language we have a huge amount of built-in computational knowledge about lots of kinds of things. But for a complete symbolic discourse language we&#8217;d have to build in additional &#8220;calculi&#8221; about general things in the world: if an object moves from A to B and from B to C, then it&#8217;s moved from A to C, etc. </p>\n<p>Given a symbolic discourse language we might use it to make &#8220;standalone statements&#8221;. But we can also use it to ask questions about the world, &#8220;Wolfram|Alpha style&#8221;. Or we can use it to state things that we &#8220;want to make so&#8221;, presumably with some external actuation mechanism. Or we can use it to make assertions—perhaps about the actual world, or perhaps about some specific world we&#8217;re considering, fictional or otherwise. </p>\n<p>Human language is fundamentally imprecise, not least because it isn&#8217;t &#8220;tethered&#8221; to a specific computational implementation, and its meaning is basically defined just by a &#8220;social contract&#8221; between its users. But computational language, by its nature, has a certain fundamental precision—because in the end what it specifies can always be &#8220;unambiguously executed on a computer&#8221;. Human language can usually get away with a certain vagueness. (When we say &#8220;planet&#8221; does it include exoplanets or not, etc.?) But in computational language we have to be precise and clear about all the distinctions we&#8217;re making.</p>\n<p>It&#8217;s often convenient to leverage ordinary human language in making up names in computational language. But the meanings they have in computational language are necessarily precise—and might or might not cover some particular connotation in typical human language usage.</p>\n<p>How should one figure out the fundamental &#8220;ontology&#8221; suitable for a general symbolic discourse language? Well, it&#8217;s not easy. Which is perhaps why little has been done since the primitive beginnings Aristotle made more than two millennia ago. But it really helps that today we now know so much about how to think about the world computationally (and it doesn&#8217;t hurt to have a &#8220;fundamental metaphysics&#8221; from our <a href=\"https://www.wolframphysics.org/\" target=\"_blank\" rel=\"noopener\">Physics Project</a> and the <a href=\"https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/\">idea of the ruliad</a>).</p>\n<p>But what does all this mean in the context of ChatGPT? From its training ChatGPT has effectively &#8220;pieced together&#8221; a certain (rather impressive) quantity of what amounts to semantic grammar. But its very success gives us a reason to think that it&#8217;s going to be feasible to construct something more complete in computational language form. And, unlike what we&#8217;ve so far figured out about the innards of ChatGPT, we can expect to design the computational language so that it&#8217;s readily understandable to humans.</p>\n<p>When we talk about semantic grammar, we can draw an analogy to syllogistic logic. At first, syllogistic logic was essentially a collection of rules about statements expressed in human language. But (yes, two millennia later) <a href=\"https://writings.stephenwolfram.com/2018/11/logic-explainability-and-the-future-of-understanding/#the-history\">when formal logic was developed</a>, the original basic constructs of syllogistic logic could now be used to build huge &#8220;formal towers&#8221; that include, for example, the operation of modern digital circuitry. And so, we can expect, it will be with more general semantic grammar. At first, it may just be able to deal with simple patterns, expressed, say, as text. But once its whole computational language framework is built, we can expect that it will be able to be used to erect tall towers of &#8220;generalized semantic logic&#8221;, that allow us to work in a precise and formal way with all sorts of things that have never been accessible to us before, except just at a &#8220;ground-floor level&#8221; through human language, with all its vagueness.</p>\n<p>We can think of the construction of computational language—and semantic grammar—as representing a kind of ultimate compression in representing things. Because it allows us to talk about the essence of what&#8217;s possible, without, for example, dealing with all the &#8220;turns of phrase&#8221; that exist in ordinary human language. And we can view the great strength of ChatGPT as being something a bit similar: because it too has in a sense &#8220;drilled through&#8221; to the point where it can &#8220;put language together in a semantically meaningful way&#8221; without concern for different possible turns of phrase.</p>\n<p>So what would happen if we applied ChatGPT to underlying computational language? The computational language can describe what&#8217;s possible. But what can still be added is a sense of &#8220;what&#8217;s popular&#8221;—based for example on reading all that content on the web. But then—underneath—operating with computational language means that something like ChatGPT has immediate and fundamental access to what amount to ultimate tools for making use of potentially irreducible computations. And that makes it a system that can not only &#8220;generate reasonable text&#8221;, but can expect to work out whatever can be worked out about whether that text actually makes &#8220;correct&#8221; statements about the world—or whatever it&#8217;s supposed to be talking about. </p>\n<h2 id=\"so-...-what-is-chatgpt-doing,-and-why-does-it-work?\">So &#8230; What Is ChatGPT Doing, and Why Does It Work?</h2>\n<p>The basic concept of ChatGPT is at some level rather simple. Start from a huge sample of human-created text from the web, books, etc. Then train a neural net to generate text that&#8217;s &#8220;like this&#8221;. And in particular, make it able to start from a &#8220;prompt&#8221; and then continue with text that&#8217;s &#8220;like what it&#8217;s been trained with&#8221;.</p>\n<p>As we&#8217;ve seen, the actual neural net in ChatGPT is made up of very simple elements—though billions of them. And the basic operation of the neural net is also very simple, consisting essentially of passing input derived from the text it&#8217;s generated so far &#8220;once through its elements&#8221; (without any loops, etc.) for every new word (or part of a word) that it generates.</p>\n<p>But the remarkable—and unexpected—thing is that this process can produce text that&#8217;s successfully &#8220;like&#8221; what&#8217;s out there on the web, in books, etc. And not only is it coherent human language, it also &#8220;says things&#8221; that &#8220;follow its prompt&#8221; making use of content it&#8217;s &#8220;read&#8221;. It doesn&#8217;t always say things that &#8220;globally make sense&#8221; (or correspond to correct <nobr>computations)—</nobr>because (without, for example, <a href=\"https://writings.stephenwolfram.com/2023/01/wolframalpha-as-the-way-to-bring-computational-knowledge-superpowers-to-chatgpt/\">accessing the &#8220;computational superpowers&#8221; of Wolfram|Alpha</a>) it&#8217;s just saying things that &#8220;sound right&#8221; based on what things &#8220;sounded like&#8221; in its training material. </p>\n<p>The specific engineering of ChatGPT has made it quite compelling. But ultimately (at least until it can use outside tools) ChatGPT is &#8220;merely&#8221; pulling out some &#8220;coherent thread of text&#8221; from the &#8220;statistics of conventional wisdom&#8221; that it&#8217;s accumulated. But it&#8217;s amazing how human-like the results are. And as I&#8217;ve discussed, this suggests something that&#8217;s at least scientifically very important: that human language (and the patterns of thinking behind it) are somehow simpler and more &#8220;law like&#8221; in their structure than we thought. ChatGPT has implicitly discovered it. But we can potentially explicitly expose it, with semantic grammar, computational language, etc.</p>\n<p>What ChatGPT does in generating text is very impressive—and the results are usually very much like what we humans would produce. So does this mean ChatGPT is working like a brain? Its underlying artificial-neural-net structure was ultimately modeled on an idealization of the brain. And it seems quite likely that when we humans generate language many aspects of what&#8217;s going on are quite similar.</p>\n<p>When it comes to training (AKA learning) the different &#8220;hardware&#8221; of the brain and of current computers (as well as, perhaps, some undeveloped algorithmic ideas) forces ChatGPT to use a strategy that&#8217;s probably rather different (and in some ways much less efficient) than the brain. And there&#8217;s something else as well: unlike even in typical algorithmic computation, ChatGPT doesn&#8217;t internally &#8220;have loops&#8221; or &#8220;recompute on data&#8221;. And that inevitably limits its computational capability—even with respect to current computers, but definitely with respect to the brain.</p>\n<p>It&#8217;s not clear how to &#8220;fix that&#8221; and still maintain the ability to train the system with reasonable efficiency. But to do so will presumably allow a future ChatGPT to do even more &#8220;brain-like things&#8221;. Of course, there are plenty of things that brains don&#8217;t do so well<span style=\"font-size:14px\">—</span>particularly involving what amount to irreducible computations. And for these both brains and things like ChatGPT have to seek &#8220;outside tools&#8221;—like <a href=\"https://www.wolfram.com/language/\">Wolfram Language</a>.</p>\n<p>But for now it&#8217;s exciting to see what ChatGPT has already been able to do. At some level it&#8217;s a great example of the fundamental scientific fact that large numbers of simple computational elements can do remarkable and unexpected things. But it also provides perhaps the best impetus we&#8217;ve had in two thousand years to understand better just what the fundamental character and principles might be of that central feature of the human condition that is human language and the processes of thinking behind it.</p>\n<h2 id='thanks' style='font-size:1.2rem'>Thanks</h2>\n<p style='font-size:90%'>I&#8217;ve been following the development of neural nets now for about 43 years, and during that time I&#8217;ve interacted with many people about them.

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&rsquo;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&rsquo;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&rsquo;option « <em>Exécuter en tant qu&rsquo;administrateur</em> » pour ouvrir une fenêtre d&rsquo;invite de commandes avec les droits admin qui vont bien. Une fois dans l&rsquo;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&rsquo;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&rsquo;est vraiment la meilleure des options même si cela implique d&rsquo;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&rsquo;est pas ouf niveau sécurité mais c&rsquo;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&#8217;emplacement de votre disque (ici c&rsquo;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>.

Le paramètre -H est utilisé pour spécifier que le domaine sera scanné toutes les 1 heures, et bien sûr, vous pouvez personnaliser cela.

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&rsquo;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&rsquo;utilisation de la méthode <code>Math.random()</code> pour générer le mot de passe administrateur. Cette méthode n&rsquo;est pas cryptographiquement sécurisée, et un attaquant pourrait récupérer suffisamment d&rsquo;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&rsquo;équipe de recherche a découvert qu&rsquo;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&rsquo;est pas si simple : pour exécuter l&rsquo;attaque, il faut d&rsquo;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&rsquo;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&rsquo;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&rsquo;importance d&rsquo;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&rsquo;utilisez pas <code>Math.random()</code> pour générer des nombres aléatoires quand il s&rsquo;agit de faire de la sécurité. À la place, il est recommandé d&rsquo;utiliser l&rsquo;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&rsquo;hui nous allons voir comment les choses ont évoluées ces derniers mois et comment le logiciel s&rsquo;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&rsquo;abord on va commencer par resituer un peu ce que propose cet outil open source (le code&nbsp;est sur Github). En gros il s&rsquo;agit d&rsquo;une suite bureautique complète (digne de Google Workspace, Zoho&nbsp;ou Microsoft 365) &#8230; sauf qu&rsquo;elle peut s&rsquo;autohéberger ! Vous pouvez donc disposer d&rsquo;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&nbsp;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&rsquo;il est possible de collaborer). Cela va du fichier traitement de texte classique, au tableur en passant par la réalisation de formulaires ou de&nbsp;présentations ou encore la création d&rsquo;ebooks. Et ça, c&rsquo;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 &#8230;), créer des sessions de groupe (avec chat et vidéocall), inviter des utilisateurs et bientôt des sessions privées. Pour les entreprises il y a l&rsquo;option Workspace qui permet non seulement de gérer vos documents, mais aussi de proposer des adresses mails corporate, un CRM,&nbsp;de créer des&nbsp;calendriers partagés&nbsp;et faire de la gestion de projets. Bref vous le voyez c&rsquo;est très complet et ça explique les 10+ millions d&rsquo;utilisateurs (dont Fujitsu, Deloitte, Seafile &#8230;) !</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&rsquo;ajout d&rsquo;un éditeur pour les fichiers PDF (très attendu j&rsquo;imagine vu la popularité du format surtout dans les entreprises). Pour l&rsquo;instant il n&rsquo;est pas encore possible d&rsquo;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&rsquo;équipe derrière le projet a aussi continué à prendre en compte les retours d&rsquo;utilisateurs pour mettre en place les améliorations les plus demandées. Comme la césure automatique, la mémorisation de paramètres lors de l&rsquo;ouverture de fichiers CSV &#8230; et une fonctionnalité d&rsquo;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&nbsp;habituelles mises à jour d&rsquo;amélioration des outils (effets de transitions dans l&rsquo;outil de présentation, tableaux croisés dynamiques dans le tableur &#8230;), de l&rsquo;interface, quelques bugs, etc.&nbsp;</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,&nbsp;Box (depuis quelques jours seulement)&nbsp;&#8230; 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&nbsp;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.&nbsp;</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&rsquo;on retrouve dans pas mal d&rsquo;autres logiciels&nbsp;de sécu&nbsp;(comme les&nbsp;gestionnaires de mots de passe par exemple). L&rsquo;outil est aussi, bien entendu, respectueux du RGPD (ou HIPAA&nbsp;si vous habitez aux&nbsp;US) et supporte la conversion d&rsquo;un tas d&rsquo;extensions (xls, ods, doc, html, epub, xml, ppt &#8230; plusieurs dizaines).</p>\n\n\n\n<p>Ah oui, et juste pour le mentionner, c&rsquo;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&rsquo;ONLYOFFICE Docs</a> est disponible pour Windows, macOS et Linux. Vous pouvez d&rsquo;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&rsquo;ai réalisée l&rsquo;an dernier sur le sujet. Tout n&rsquo;est pas 100% à jour, mais dans les très grandes lignes ça reste d&rsquo;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 &#8230; 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&rsquo;est qu&rsquo;elle garantit la confidentialité de vos données, puisque tout est traité localement.</p>\n\n\n\n<p>Le modèle Whisper d&rsquo;OpenAI a bien sûr quelques petits défauts, comme l&rsquo;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&rsquo;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&rsquo;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.

La vitesse de transcription dépendra de votre ordinateur et de la mémoire disponible et, bien que l&rsquo;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&rsquo;en est-il de la transcription en temps réel ? Et bien, c&rsquo;est prévu, mais d&rsquo;autres demandes sont prioritaires pour le moment d&rsquo;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&rsquo;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&rsquo;application prend en charge uniquement la traduction en anglais pour le moment, mais qui sait ce que l&rsquo;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&rsquo;espère que cette présentation d&rsquo;Aiko vous a plu et que vous êtes aussi enthousiastes que moi à l&rsquo;idée de l&rsquo;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&rsquo;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.&nbsp;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&nbsp;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&nbsp;du côté de&nbsp;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.&nbsp;Et&nbsp;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).&nbsp;Notamment à cause du climat mondial&nbsp;toujours plus tendu : guerre en Ukraine, augmentation continue des attaques informatiques&nbsp;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",

Le torrent ? On adore ça. Mais le mieux c&rsquo;est encore d&rsquo;héberger vous-même votre Netflix personnel.</p>\n\n\n\n<p>Et pour ça, on peut compter sur <strong>Movie-web</strong>, une application web géniale hébergeable sur votre propre serveur ou ordi perso, qui vous permet de regarder tous vos films et séries préférés dans une interface intuitive et esthétique, sans publicités !</p>\n\n\n\n<p>Au niveau de l&rsquo;interface, c&rsquo;est assez simple. En allant dans les paramètres, vous pouvez choisir le français comme langue pour l&rsquo;interface ainsi que la langue préférée, la taille et la couleur pour vos sous-titres.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"955\" height=\"473\" src=\"https://korben.info/app/uploads/2023/10/SCR-20231009-l6u.webp\" alt=\"\" class=\"wp-image-154425\" srcset=\"https://korben.info/app/uploads/2023/10/SCR-20231009-l6u.webp 955w, https://korben.info/app/uploads/2023/10/SCR-20231009-l6u-300x149.webp 300w, https://korben.info/app/uploads/2023/10/SCR-20231009-l6u-768x380.webp 768w\" sizes=\"(max-width: 955px) 100vw, 955px\" /></figure></div>\n\n\n<p>Ensuite, y&rsquo;a plus qu&rsquo;à chercher un film via le moteur de recherche. Evitez quand même les films copyrights et cherchez exclusivement les films sous licence libre afin de ne pas sombrer dans le piratage bête et méchant. Donc au lieu de mater la dernière saison de OnePiece ou Barbie le film, j&rsquo;ai trouvé quand même beaucoup plus cool de revoir ce fameux film de Georges Méliès : <em>Le Voyage Dans La Lune</em> de 1902. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"904\" src=\"https://korben.info/app/uploads/2023/10/SCR-20231009-laz-1024x904.png\" alt=\"\" class=\"wp-image-154426\" srcset=\"https://korben.info/app/uploads/2023/10/SCR-20231009-laz-1024x904.png 1024w, https://korben.info/app/uploads/2023/10/SCR-20231009-laz-300x265.png 300w, https://korben.info/app/uploads/2023/10/SCR-20231009-laz-768x678.png 768w, https://korben.info/app/uploads/2023/10/SCR-20231009-laz.png 1087w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-121357552\" 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 hop, immédiatement le film est trouvé sur la toile et lu dans le player web de Movie Web.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"929\" src=\"https://korben.info/app/uploads/2023/10/SCR-20231009-lbl-1024x929.webp\" alt=\"\" class=\"wp-image-154427\" srcset=\"https://korben.info/app/uploads/2023/10/SCR-20231009-lbl-1024x929.webp 1024w, https://korben.info/app/uploads/2023/10/SCR-20231009-lbl-300x272.webp 300w, https://korben.info/app/uploads/2023/10/SCR-20231009-lbl-768x697.webp 768w, https://korben.info/app/uploads/2023/10/SCR-20231009-lbl.webp 1111w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Parmi les fonctionnalités offertes par Movie-web, on compte la <strong>sauvegarde de la progression</strong> de vos films et séries, ce qui vous permet de reprendre là où vous vous êtes arrêté, même si vous changez d&rsquo;appareil. Vous pouvez également ajouter des <strong>signets</strong> pour vos films et épisodes préférés, et passer facilement d&rsquo;une saison à l&rsquo;autre ou d&rsquo;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&rsquo;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&rsquo;application</strong></a> (il vous faudra un compte Cloudflare), ce qui donne un contrôle total sur l&rsquo;expérience de visionnage.</p>\n\n\n\n<p>Movie Web n&rsquo;est donc rien de plus qu&rsquo;un moteur de recherche capable de trouver le film de vos rêves, principalement en VO, sur la toile. Quelle bonne idée surtout que c&rsquo;est totalement sous licence libre !</p>\n\n\n\n<p>Et si vous voulez une démo du service, je crois qu&rsquo;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",

Mare qui est encore un peu vide vu le manque de flotte en ce moment.</p>\n\n\n\n<p> J&rsquo;ai également passé 2 semaines en Bretagne en août, esquivant la canicule puis en septembre, j&rsquo;ai décidé de passer à la semaine de 3 jours, car, vous le savez, la vraie richesse, c&rsquo;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&rsquo;écris mes articles et j&rsquo;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&rsquo;est que c&rsquo;est plutôt un semi-weekend. C&rsquo;est-à-dire que je bosse quand même un peu durant ces jours-là, car j&rsquo;ai évidemment des trucs que je n&rsquo;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&rsquo;est que c&rsquo;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&rsquo;as pas le temps de t&rsquo;amuser, y&rsquo;a encore ça à faire, puis ça, puis ça, et la semaine prochaine, y&rsquo;a ça, encore ça&#8230;</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&rsquo;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.",

C&rsquo;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&rsquo;horreur, autant vous dire que c&rsquo;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&rsquo;est pas une suite, c&rsquo;est d&rsquo;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&rsquo;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&rsquo;être assez créatif. En plus de tirer avec ses flingues (on peut porter jusqu&rsquo;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&rsquo;un ennemi comme bouclier, on peut se rendre invisible mais aussi activer un mode « bullet time » qui s&rsquo;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&rsquo;est super propre, fluide, mais surtout y a une excellente ambiance qui s&rsquo;installe. Y a un côté John Wick / Matrix, mélangé à du surnaturel et parfois même de l&rsquo;horreur&#8230; Je vous ai dit que c&rsquo;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&rsquo;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&rsquo;armes, c&rsquo;est sympa mais les niveaux n&rsquo;invitent pas forcément à l&rsquo;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&rsquo;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&rsquo;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&rsquo;ennemis de plus en plus nombreux et puissants, bref, de quoi allonger la durée de vie. 🙂</p>\n\n\n\n<p>L&rsquo;histoire principale se boucle une première fois en 4-5h, et je pense qu&rsquo;on peut largement doubler le temps de jeu avec ce contenu supplémentaire. C&rsquo;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&rsquo;une fois, et ce n&rsquo;est que le deuxième mode de difficulté sur&#8230; 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&rsquo;est un excellent jeu de tir « défouloir », super fun, avec quelques moments bien flippants, et une bonne liberté dans notre manière d&rsquo;appréhender les différentes situations périlleuses dans lesquels les développeurs adorent nous coincer. Bien sûr, faut aimer le genre, mais si c&rsquo;est votre cas je pense qu&rsquo;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&rsquo;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&rsquo;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&rsquo;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.

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&rsquo;être un expert en IA ou un codeur de l&rsquo;extrême pour l&rsquo;utiliser !</p>\n\n\n\n<p>Roop est un projet développé pour le plaisir et contrairement à d&rsquo;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&rsquo;utiliser leurs visages et surtout de ne pas dissimuler qu&rsquo;il s&rsquo;agit d&rsquo;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&rsquo;utilisation malveillante (et moi aussi je décline&#8230;). 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&rsquo;installation</strong> : basique et avec accélération GPU. L&rsquo;installation basique est plus efficace mais beaucoup plus lente. Pour l&rsquo;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&rsquo;image/vidéo cible, puis cliquez sur « Start ». La sortie sera enregistrée dans un dossier nommé <code>&lt;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&rsquo;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&rsquo;argument <code>-f / --face</code> lors du lancement. </p>\n\n\n\n<p>Les futurs projets pour Roop incluent l&rsquo;amélioration de la qualité des visages, le remplacement sélectif d&rsquo;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&rsquo;initier au monde des deepfakes. Que ce soit pour créer des vidéos humoristiques ou pour explorer les possibilités offertes par l&rsquo;IA, Roop est un excellent point de départ. Mais n&rsquo;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&rsquo;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",

On en a vu de toutes les couleurs, des plus simples aux plus complexes, avec des interfaces graphiques variées plus ou moins foirées. Mais aujourd&rsquo;hui, je vais vous parler d&rsquo;un gestionnaire de fichiers qui sort des sentiers battus : <strong>TUIFIManager</strong>. Ce petit bijou fonctionne dans le terminal et vous allez l&rsquo;adorer !</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1048945498\" 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>Alors, pourquoi choisir TUIFIManager plutôt qu&rsquo;un autre gestionnaire de fichiers ? Tout d&rsquo;abord, il est <strong>multiplateforme</strong>. Que vous soyez sous Linux, macOS ou Windows, TUIFIManager fonctionnera sans problème. Ensuite, il est <strong>léger</strong> et <strong>rapide</strong> et ne consommera pas toute votre RAM tout en offrant une expérience utilisateur fluide.</p>\n\n\n\n<p>Mais ce n&rsquo;est pas tout puisque TUIFIManager est également <strong>personnalisable</strong>. Vous pouvez modifier son comportement en utilisant des <strong>variables d&rsquo;environnement</strong>. Vous avez envie de changer la couleur du texte, la taille de la police ou la disposition des éléments ? Pas de problème, TUIFIManager vous permet de le faire facilement.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"787\" height=\"448\" src=\"https://korben.info/app/uploads/2023/06/ezgif.com-webp-maker.gif\" alt=\"\" class=\"wp-image-153140\"/></figure></div>\n\n\n<p>En plus de tout cela, TUIFIManager prend en charge la <strong>souris</strong>. Vous pouvez donc cliquer sur votre mulot comme un dingue pour naviguer dans vos fichiers, sélectionner des éléments et effectuer toutes sortes d&rsquo;actions. Et si vous préférez utiliser le clavier, TUIFIManager vous offre également des <strong>raccourcis clavier</strong> afin de faciliter votre navigation.</p>\n\n\n\n<p>Le projet TUIFIManager est en constante évolution et les développeurs travaillent sans relâche pour ajouter de nouvelles fonctionnalités et améliorer les performances. Pour installer TUIFIManager, il vous suffit d&rsquo;utiliser la commande suivante :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>pip3 install TUIFIManager --upgrade</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-311841574\" 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 encourage également à vous rendre sur le dépôt GitHub et à suivre les explications fournies pour utiliser au mieux toutes les fonctionnalités de TUIFIManager mais également le personnaliser.</p>\n\n\n\n<p><a href=\"https://github.com/GiorgosXou/TUIFIManager\" target=\"_blank\" rel=\"noopener\"><strong>À découvrir ici</strong></a></p>\n",

Heureusement, il y a des outils pour faire le ménage et retrouver un peu d&rsquo;ordre dans notre joyeux bazar numérique. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-290867064\" 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 aujourd&rsquo;hui, mes amis, je vais vous parler d&rsquo;une perle rare que j&rsquo;ai dénichée pour vous : <strong>Czkawka</strong> !</p>\n\n\n\n<p>Admettons que vous ayez accumulé des tonnes de fichiers en double, des dossiers vides et d&rsquo;autres éléments inutiles qui prennent de la place sur votre disque dur.

Tout d&rsquo;abord, c&rsquo;est un lanceur <strong>Open Source</strong>, ce qui signifie que nous avons la possibilité d&rsquo;examiner le code source et même de contribuer à son développement. De plus, il consomme vachement moins de ressources que l&rsquo;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&rsquo;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&rsquo;on veut naviguer entre la boutique et la bibliothèque d&rsquo;EGL, cela prend environ 2 secondes alors qu&rsquo;avec Heroic c&rsquo;est pratiquement instantané. En plus de cela, Heroic prend également beaucoup moins d&rsquo;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&rsquo;il y a encore un peu de travail à faire sur Heroic en termes d&rsquo;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&rsquo;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&rsquo;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 &#8211; 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",

Il transcrit la parole en texte, créant ainsi des sous-titres SRT précis dans la langue choisie. Simple d&rsquo;utilisation, Subtitlr est compatible avec <strong>Linux, MacOS et Windows</strong>.</p>\n\n\n\n<p>Pour commencer, vous devez d&rsquo;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&rsquo;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&rsquo;en avez pas encore, rendez-vous sur le site d&rsquo;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 &lt;votre_clé_API_OpenAI&gt; --url &lt;URL_de_la_vidéo_YouTube&gt; --language &lt;langue_des_sous-titres&gt;</code></p>\n\n\n\n<p>Remplacez <code>&lt;votre_clé_API_OpenAI&gt;</code> par votre clé API, <code>&lt;URL_de_la_vidéo_YouTube&gt;</code> par l&rsquo;URL de la vidéo pour laquelle vous souhaitez générer des sous-titres, et <code>&lt;langue_des_sous-titres&gt;</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 !

Cela fait maintenant plus de 2 ans que je l&rsquo;utilise personnellement et que j&rsquo;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&rsquo;agit de la suite qui vous permet de surveiller et de gérer l&rsquo;ensemble de vos protections sur le service. VPN, antivirus, système d&rsquo;alerte, fuites de données, moteur de recherche, etc &#8230; tout est inclus dans One. Depuis peu, ils ont même ajouté la <strong>fonctionnalité Alternative-ID</strong> (j&rsquo;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&rsquo;abord, le point central de l&rsquo;écosystème et la raison d&rsquo;être de surfshark, à savoir le VPN. J&rsquo;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 &amp; 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&rsquo;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&rsquo;ai aussi présentée en détail. Bref rien que pour le VPN c&rsquo;est de la balle, mais One dispose d&rsquo;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&rsquo;importe quel autre outil du même genre. À savoir qu&rsquo;il vous offrira une protection en temps réel de vos appareils.&nbsp;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,&nbsp;phishing&nbsp;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&rsquo;<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&rsquo;est leur moteur de recherche maison. Celui-ci ne propose que des résultats organiques et respectant votre vie privée.&nbsp; savoir qu&rsquo;il n&rsquo;enregistre pas vos infos, n&rsquo;autorise ni les publicités ni les traqueurs, etc. Pas de ciblage donc, et pas de résultats qui s&rsquo;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&rsquo;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 &#8230;), 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&rsquo;allez l&rsquo;utiliser qu&rsquo;une seule fois ? Utilisez votre alter ego. Ainsi ils n&rsquo;auront pas vos données privées à exploiter dans le futur. Votre profil peut s&rsquo;autodétruire au bout d&rsquo;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&nbsp;outils est disponible pour 4.49€/mois si vous prenez l&rsquo;abonnement&nbsp;1 an (soit 53.88€ l&rsquo;année, économie de -75%). Ou combiner One avec le service Surfshark&nbsp;Incogni (One+) pour 6.23€/mois.</p>\n\n\n\n<p>L&rsquo;avantage principal de cette suite est de tout regrouper au sein d&rsquo;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&rsquo;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&amp;aff_id=13768\" target=\"_blank\" rel=\"noopener\">Découvrir Surfshark One</a></h2>\n",

Eh bien, mes amis, je suis ravi de vous présenter aujourd&rsquo;hui WingmanAI, un outil puissant qui fait exactement cela !</p>\n\n\n\n<p>WingmanAI est donc un logiciel qui permet d&rsquo;obtenir une transcription en temps réel à la fois de l&rsquo;audio de votre ordinateur mais également de votre micro. De plus, boosté par ChatGPT, cet outil vous permet également d&rsquo;interagir en temps réel avec les transcriptions. Hé oui, grâce à WingmanAI, il est possible de discuter avec un bot alimenté par ChatGPT qui a un accès à vos transcriptions en temps réel.</p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls src=\"https://korben.info/app/uploads/2023/06/241472868-6f9f8e09-f43e-47d5-87ae-ac5bc693963d-2.mp4\"></video></figure>\n\n\n\n<p>Evidemment, il est possible de continuer à ajouter des conversations aux transcriptions existante, ce qui permettra progressivement de se construire une vaste base de données au fil du temps. 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. Je vous invite également à y jeter un oeil.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1768274060\" 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 installer WingmanAI, vous devez cloner le dépôts et installer les dépendances. 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",

Pour le réparer et que tout rentre dans l&rsquo;ordre, il va falloir stopper des crimes avant qu&rsquo;ils ne soient commis. Ouais, c&rsquo;est un peu le concept de Minority Report mais en beaucoup plus mignon, que nous propose Crime O&rsquo;Clock, jeu d&rsquo;enquête dispo <a href=\"https://www.nintendo.com/store/products/crime-oclock-switch/\" target=\"_blank\" rel=\"noopener\">sur Nintendo Switch</a> et <a href=\"https://store.steampowered.com/app/1736290/Crime_OClock/\" target=\"_blank\" rel=\"noopener\">PC (Steam)</a>. Sortez votre plus grosse loupe et affutez votre esprit de déduction, c&rsquo;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&#039;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&rsquo;est le principe de base sur lequel s&rsquo;appuie le <em>gameplay</em> : fouiller l&rsquo;environnement, retrouver des personnages&#8230; Mais aussi analyser leurs faits et gestes. 🤔 La (première) grosse différence, c&rsquo;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&rsquo;autres outils d&rsquo;analyse seront proposés, avec des petits puzzles à résoudre ou des mécanismes à activer, pour obtenir d&rsquo;autres indices ou « filtres » nous permettant d&rsquo;y voir plus clair. 🙈 On en découvre de nouveaux régulièrement, c&rsquo;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&rsquo;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&rsquo;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&rsquo;est mignon comme tout, plutôt clair et lisible, fluide, rien à redire. On s&rsquo;amusera à dénicher certains personnages « connus »&#8230; 😉 La musique manque un peu de pêche et de variété, disons qu&rsquo;il n&rsquo;y a rien de remarquable, mais c&rsquo;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&rsquo;est un jeu tout public, accessible à n&rsquo;importe quel âge, ça peut être sympa de le diffuser sur la grand télé du salon et fouiller l&rsquo;écran en famille. 🕵️ Et je pense que les gamins se prendront facilement au jeu. Après, il faut aimer le genre. C&rsquo;est assez spécial, assez « basique », mais j&rsquo;aime bien, ça détend ! Ça se joue sans aucune pression, c&rsquo;est agréable, je trouve que <strong>c&rsquo;est un bon 🔎🔎🔎/5</strong></p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">Retrouver Crime O&rsquo;Clock <a href=\"https://www.nintendo.com/store/products/crime-oclock-switch/\" target=\"_blank\" rel=\"noopener\">sur Nintendo Switch</a> &amp; <a href=\"https://store.steampowered.com/app/1736290/Crime_OClock/\" target=\"_blank\" rel=\"noopener\">PC (Steam)</a></h2>\n",

Cette télécommande faite elle aussi maison, est dotée d&rsquo;une paire de joysticks et dispose d&rsquo;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&rsquo;équilibre sur une surface courbe, l&rsquo;ajustement de la hauteur du corps sous l&rsquo;effet de la pression et l&rsquo;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&rsquo;un détecteur de gaz dangereux et peut même servir de station mobile en lançant un petit drone !

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: &#91;1] &#91;2], &#91;3], &#91;4], &#91;5], &#91;6], &#91;7], &#91;8], &#91;9], &#91;10]: &#91;1] Initiate each prompt with \"/imagine prompt &lt;number>: \" &#91;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, ...\" &#91;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, ...\" &#91;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, ...\" &#91;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 ...\" &#91;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, ...\" &#91;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, ...\" &#91;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, ...\" &#91;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. &#91;10] End the prompt with \" --s 1000\" to complete the string. Additional instructions to remember: Compose steps &#91;1] to &#91;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&rsquo;est une vraie mine d&rsquo;or à explorer.</p>\n\n\n\n<p>Bref, c&rsquo;est <a href=\"https://flowgpt.com/\" target=\"_blank\" rel=\"noopener\">à découvrir ici</a>.</p>\n",

Imaginez un monde où nous pouvons surfer sans devoir faire attention à rien ni personne, sans utiliser de service particulier. Sans antivirus, firewall, VPN, gestionnaire de mots de passe&nbsp;&amp; Co. Hein ? Oh, j&rsquo;étais en train de rêver les yeux ouverts ? Désolé j&rsquo;étais toujours en vacances dans ma tête &#8230; revenons à la dure réalité 😉</p>\n\n\n\n<p>En attendant, profitons des outils à notre disposition et de ce que propose le VPN Surfshark avec Incogni. Ce sera toujours ça de prit sur le respect de notre vie privée numérique. D&rsquo;ailleurs comme nous allons le voir, les attaques à notre égard ne sont pas toujours frontales. Il y a parfois des petits malins qui font des choses sales dans notre dos.</p>\n\n\n\n<p>C&rsquo;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 &#8230;), les combiner pour fabriquer un profil le plus précis et les vendre à nouveau au plus offrant (banques, assurances, agences marketing &amp; co). Et en France cela va même parfois jusqu&rsquo;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&rsquo;est une somme d&rsquo;argent créditée aux travailleurs (500€)&nbsp;chaque année&nbsp;(et jusqu&rsquo;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&rsquo;heures, mais depuis que la monnaie sonnante et trébuchante est de la partie, cela attire les convoitises. Quasi 50 millions par an&nbsp;finissent dans les poches des arnaqueurs et cela ne fait qu&rsquo;augmenter. </p>\n\n\n\n<p>C&rsquo;est beaucoup. Et comme chacun a le droit de dépenser son crédit comme il en a envie, il n&rsquo;y a pas d&rsquo;autre barrière que le choix du concerné pour savoir où part cet argent. Pas de surprise donc, les escrocs se&nbsp;sont vite&nbsp;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&rsquo;est juste qu&rsquo;il n&rsquo;y a rien derrière les murs. Parfois difficile pour quelqu&rsquo;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&rsquo;est à la base pas vraiment&nbsp;à eux.</p>\n\n\n\n<p>Du coup pour les arnaqueurs il y a un besoin d&rsquo;informations personnalisées. Histoire d&rsquo;envoyer du spam ciblé ou des campagnes de phishing, de vous&nbsp;téléphoner directement&nbsp;ou de contacter ceux qui répondront le mieux à leurs propositions.&nbsp;Pour cela&nbsp;ils passent le plus souvent par les data brokers cités ci-dessus. La meilleure défense est donc de ne pas se retrouver dans&nbsp;leurs bases de données.&nbsp;<a href=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">C&rsquo;est là que la solution&nbsp;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&rsquo;ai expliqué à plusieurs reprises, le but d&rsquo;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&rsquo;action, ils prennent bien le temps de leur rappeler aux sanctions auxquelles ils s&rsquo;exposent s&rsquo;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&rsquo;est de vous abonner et expliquer à Incogni quelles informations vous ne voulez plus voir circuler. Vous êtes donc flexible, ce qui peut s&rsquo;avérer pratique selon les cas de chacun. Par exemple vous pourriez décider que votre numéro de téléphone et&nbsp;votre nom sont hors limites et ne devraient être partagés dans aucun cas, alors que votre adresse mail n&rsquo;est pas un problème. J&rsquo;ai d&rsquo;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&rsquo;Incogni</a> au bout d&rsquo;un an d&rsquo;utilisation pour que vous vous rendiez compte de comment ça se passe.</p>\n\n\n\n<p>Autre bon point, c&rsquo;est de pouvoir se rendre compte&nbsp;de manière concrète que vos informations tournent dans votre dos. À moins d&rsquo;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 &#8230; 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&rsquo;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&nbsp;et vous réaliserez mieux ce qu&rsquo;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&amp;aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Testez Incogni !</a></h2>\n",

C&rsquo;est le premier agent d&rsquo;apprentissage continu qui utilise des modèles de langage dans l&rsquo;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&rsquo;est ça Voyager.</p>\n\n\n\n<p>Ce nouvel agent intelligent se compose de trois éléments clés : un programme d&rsquo;analyse automatique pour maximiser l&rsquo;exploration, une bibliothèque capable de s&rsquo;enrichir continuellement avec compétences et des comportements complexes ainsi qu&rsquo;un mécanisme capable de commenter en continu l&rsquo;environnement et d&rsquo;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&rsquo;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&rsquo;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&rsquo;objets uniques, explorer des distances 2,3 fois plus longues et progresser dans l&rsquo;arbre technologique jusqu&rsquo;à 15,3 fois plus rapidement que n&rsquo;importe quel programme similaire actuel. Incroyable, non ?</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"617\" src=\"https://korben.info/app/uploads/2023/06/exploration_performance.webp\" alt=\"\" class=\"wp-image-153009\" srcset=\"https://korben.info/app/uploads/2023/06/exploration_performance.webp 1000w, https://korben.info/app/uploads/2023/06/exploration_performance-300x185.webp 300w, https://korben.info/app/uploads/2023/06/exploration_performance-768x474.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Maintenant que je vous ai expliqué les bases de Voyager, vous vous demandez certainement comment l&rsquo;utiliser vous-même. Et bien, pour commencer à utiliser Voyager, il faudra d&rsquo;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&rsquo;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&rsquo;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&rsquo;apprentissage, il est également possible de mettre tout ça en pause avec une simple commande et de reprendre l&rsquo;apprentissage à partir d&rsquo;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&rsquo;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&rsquo;amuser avec les records d&rsquo;autres joueurs, via un tableau des scores connecté à internet, et&#8230; C&rsquo;est à peu près tout.</p>\n\n\n\n<p>Vous allez me dire que c&rsquo;est trop léger, et vous aurez sûrement raison. C&rsquo;est de l&rsquo;arcade à l&rsquo;ancienne « tu mets une pièce et tu joues ». Mais si je vous en parle c&rsquo;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&rsquo;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&rsquo;ai le jeu sur Switch, c&rsquo;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&rsquo;est un peu léger. L&rsquo;habillage musical et graphique (menus&#8230;) est assez <em>cheap</em>. C&rsquo;est uniquement une fois sur la piste que le jeu se démarque (contrôles, sensations, sons des moteurs&#8230;). Vue intérieure/capot recommandée ! Les graphismes sont cools aussi, c&rsquo;est propre avec de jolis effets de lumière, il n&#8217;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&rsquo;il s&rsquo;agit d&rsquo;un public de niche, devraient s&rsquo;y retrouver. C&rsquo;est du fun immédiat et sans aucun artifice. Aux autres, je conseille d&rsquo;attendre une promo à moins de 10€ pour éviter toute déception !

C&rsquo;était tellement long !!!</p>\n\n\n\n<p>Bref, le projet en question dont je vais vous parler aujourd&rsquo;hui s&rsquo;appelle QuickInstall, et il sert à créer des images ISO d&rsquo;installation de Windows 98 SE optimisées afin d&rsquo;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&rsquo;utilisation d&rsquo;un Windows 98 déjà installé, sur lequel se rajouter des pilotes et des outils supplémentaires pour rendre l&rsquo;installation plus rapide et plus personnalisable. J&rsquo;aime d&rsquo;ailleurs beaucoup l&rsquo;idée de faire reposer tout ce processus d&rsquo;installation sur un Linux avec ses outils de formatage et de partionnement, ce qui permet d&rsquo;aller encore plus vite</p>\n\n\n\n<p>D&rsquo;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&rsquo;exploitation pris en charge se limitent à Windows 98, Windows 98 SE et Windows Millenium Edition. Les versions internationales n&rsquo;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&rsquo;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&rsquo;un CD/DVD-ROM, d&rsquo;une disquette de 1,44 Mo avec DOS (dosflop.img), ou d&rsquo;une disquette de 1,44 Mo avec un noyau minuscule (floppy.img). Il est aussi possible de créer des images USB amorçables à l&rsquo;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&rsquo;un logiciel pour extraire des fichiers d&rsquo;une image de disque dur (p. ex. 7zip).</p>\n\n\n\n<p>L&rsquo;utilisation du script de préparation du système (sysprep.py) permet de préparer une installation sous la forme d&rsquo;une image ISO et/ou USB. Ce script prend divers paramètres tels que la création d&rsquo;images, la spécification de répertoires racine de système Windows 98/ME, l&rsquo;ajout de pilotes supplémentaires, et bien plus encore.</p>\n\n\n\n<p>Le processus d&rsquo;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&rsquo;assurer que le pilote réseau n&rsquo;est pas installé pour éviter les problèmes. Ensuite, il faudra éteindre la machine virtuelle et utiliser un logiciel d&rsquo;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&rsquo;exécuter le script sysprep.py en suivant les instructions pour créer l&rsquo;image d&rsquo;installation optimisée.</p>\n\n\n\n<p>Pour créer une image ISO bootable, il est nécessaire d&rsquo;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&rsquo;image est prête, elle peut être écrite sur une clé USB à l&rsquo;aide de dd sous Linux ou d&rsquo;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&rsquo;installation multi-variantes en spécifiant le paramètre <code>--osroot</code> plusieurs fois. Lors de l&rsquo;installation, un menu de sélection apparaît pour permettre à l&rsquo;utilisateur de choisir la variante à installer. Ce projet est une véritable mine d&rsquo;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&rsquo;est simplement tester Windows 98, pas la peine de l&rsquo;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&rsquo;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",

"title": "Ajoutez 2 cordes à votre arc avec la formation Flutter & Dart Ambient IT",
"description": "&#8212; Article en partenariat avec Ambient IT &#8212; Salut les amis, si vous êtes développeur (ou lead dev), vous voulez peut-être profiter de la période pour ajouter une ou plusieurs cordes à votre arc. Déjà juste parce qu’il faut toujours être curieux et&#160;apprendre de nouvelles choses dans la vie (c’est &#8230; <a href=\"https://korben.info/formation-flutter-dart-ambien-it.html\">Suite</a>",

Déjà juste parce qu’il faut toujours être curieux et&nbsp;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&nbsp;open source Flutter intéressant. Ou, plus simplement,&nbsp;votre entreprise aurait intérêt à&nbsp;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&nbsp;vous permet de créer des interfaces utilisateur pour applications. L’un de ses avantages est que le code créé&nbsp;est alors&nbsp;compatible directement avec plusieurs plateformes (windows, macOS, Linux, Android, etc.). Pratique et surtout rapide. En plus, vous avez aussi à apprendre à&nbsp;maitriser le&nbsp;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&amp; 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&nbsp;&amp; 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&nbsp;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&nbsp;les widgets intégrés</li>\n\n\n\n<li>Créer votre propre interface réactive et vos&nbsp;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&nbsp;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 «&nbsp;<a href=\"https://www.ambient-it.net/formation/flutter/\" target=\"_blank\" rel=\"noopener\">Programme</a>&nbsp;» pour tout le détail). La liste est plus longue que mes 2&nbsp;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&nbsp;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&nbsp;avec&nbsp;un formateur&nbsp;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&nbsp;par plusieurs dispositifs de financement&nbsp;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.

Il s&rsquo;agit de <em>Trdsql</em>, un programme écrit en Go qui permet d&rsquo;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&rsquo;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&rsquo;est une alternative avancée à <em>q</em> et <em>textql</em>, qui offrent également la possibilité d&rsquo;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&rsquo;il gère, il propose différents formats de sortie tels qu&rsquo;une sortie brute, en table ASCII, en Markdown&#8230;etc. Un autre atout de Trdsql est qu&rsquo;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&rsquo;aide d&rsquo;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&rsquo;est donc un outil précieux pour ceux qui travaillent avec des données structurées et des fichiers « plats ». </p>\n\n\n\n<p>N&rsquo;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",

Ces projets fonctionnent tous les deux avec Docker-compose et sont incroyablement simples à déployer. </p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2108137680\" 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>WirePiUS combine WireGuard, Pi-Hole, Unbound et Stubby, vous offrant un VPN fiable et sécurisé avec DNS caching et DNS over TLS. </p>\n\n\n\n<p>RaSoPle, quant à lui, combine de nombreux outils tels que Radarr, Sonarr, Lidarr, Jackett, flaresolverr, rdt-client, Plex, Emby, ou encore Jellyfin.</p>\n\n\n\n<ul>\n<li><strong>Radarr</strong> est un gestionnaire de collection de films pour les utilisateurs d&rsquo;Usenet et BitTorrent. 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&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;obtenir des téléchargements récents (comme RSS) et d&rsquo;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&rsquo;une demande arrive, il utilise puppeteer avec le plugin stealth pour créer un navigateur headless (Firefox). Il ouvre l&rsquo;URL avec les paramètres de l&rsquo;utilisateur et attend que le défi de Cloudflare soit résolu (ou le délai d&rsquo;expiration). Le code HTML et les cookies sont renvoyés à l&rsquo;utilisateur, et ces cookies peuvent être utilisés pour contourner Cloudflare à l&rsquo;aide d&rsquo;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&rsquo;aide de Docker, vous pourrez profiter d&rsquo;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&rsquo;IP 10.2.0.100. Si aucun fichier <code>wg0.conf</code> n&rsquo;est trouvé (peut-être lors d&rsquo;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&rsquo;utiliser la configuration &lsquo;Split tunnel&rsquo;, 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&rsquo;url http://10.2.0.100/admin. Le mot de passe est vide, sauf si vous l&rsquo;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&rsquo;orchestre qui supervise tous vos téléchargements, l&rsquo;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&rsquo;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&rsquo;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&rsquo;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&#8230;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&rsquo;interagir avec Nushell via un protocole JSON-RPC simple. Les plugins peuvent alors se comporter comme des filtres ou des récepteurs (&lsquo;sink&rsquo;), 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&rsquo;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&rsquo;essayer Nushell et de profiter de ses fonctionnalités. Comme le disait le philosophe Socrate, <em>&lsquo;La vie sans un bon vieux shell ne vaut pas la peine d&rsquo;être vécue&rsquo;</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&rsquo;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",

De mon côté j&rsquo;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&rsquo;une offre bien sympa si vous avez besoin d&rsquo;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&rsquo;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 &amp; 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&rsquo;avantage de Surfshark c&rsquo;est de vous proposer <strong>une boite à outils complète et automatisée qui vous protège toute l&rsquo;année</strong>, 7 jours sur 7 et 24 heures sur 24. Mobile, laptop, tablette, ordinateur de bureau ou même SmartTV et consoles de jeux &#8230; que ce soit sous Windows, Linux, macOS, OS mobile, navigateurs (Chrome, Firefox, Edge) &#8230; toutes les configurations les plus répandues sont prises en compte. Et votre Internet n&rsquo;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&rsquo;un abonnement en supporte un nombre illimité !</p>\n\n\n\n<p>Autre avantage, ce sera d&rsquo;accéder à du contenu ou à des services qui pourraient être bloqués dans votre pays.&nbsp;Ou, au contraire, d&rsquo;avoir&nbsp;accès aux catalogues de plateformes multimédias de votre pays d&rsquo;origine ainsi que&nbsp;d&rsquo;autres&nbsp;contrées (comme Netflix ou Spotify) lorsque vous partez à l&rsquo;étranger. Assez pratique lorsqu&rsquo;on arrive dans un endroit sans s&rsquo;être renseigné&nbsp;à l&rsquo;avance&nbsp;et que l&rsquo;on découvre qu&rsquo;un site dont on a besoin&nbsp;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&amp;aff_id=13768&amp;url_id=1622\" target=\"_blank\" rel=\"noopener\">Surfshark VPN</a> vous offre également toute la panoplie des options devenues&nbsp;classiques de ce genre d&rsquo;outil. Cela va du <strong>changement automatique d&rsquo;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&rsquo;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&rsquo;explique son intérêt dans l&rsquo;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&rsquo;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&rsquo;Avira et&nbsp;va analyser en arrière-plan toutes vos machines afin de détecter virus, malwares, attaques Zéro Day&nbsp;et autres saloperies du moment. Cela de manière automatisée selon la fréquence qui vous convient,&nbsp;sans&nbsp;ralentir votre appareil (c&rsquo;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&nbsp;par mois, vous pouvez ainsi&nbsp;ajouter l&rsquo;antivirus, mais aussi un service d&rsquo;alertes, une protection webcam/micro&nbsp;et un moteur de recherche privé&nbsp;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&rsquo;outils,&nbsp;<a href=\"https://korben.info/articles/surfshark-one\" data-type=\"URL\" data-id=\"https://korben.info/articles/surfshark-one\">Surfshark One</a>, à leur&nbsp;service Incogni (Surfshark One+) dont je parle régulièrement aussi. Ce qui vous permet d&rsquo;élargir encore le spectre de protection,&nbsp;avec en plus l&rsquo;opportunité&nbsp;de faire respecter votre vie privée et retirer vos données personnelles chez les data brokers. C&rsquo;est la première fois que j&rsquo;y fais attention&nbsp;sur leur site, l&rsquo;intégration est donc dorénavant complète. Votre surf sera quasi&nbsp;full bulletproof.</p>\n\n\n\n<p>Je termine en vous rappelant que l&rsquo;offre est satisfaite ou remboursée durant 30 jours, donc vous n&rsquo;avez rien à perdre si le service ne vous convient pas ! Vous n&rsquo;avez&nbsp;plus&nbsp;aucune excuse&nbsp;pour&nbsp;avoir (enfin)&nbsp;la conscience tranquille !</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&amp;aff_id=13768&amp;url_id=1622\" data-type=\"URL\" data-id=\"https://get.surfshark.net/aff_c?offer_id=87&amp;aff_id=13768&amp;url_id=1511\" target=\"_blank\" rel=\"noreferrer noopener\">Profitez de l&rsquo;offre à 2,21 €/mois de Surfshak VPN</a></h2>\n",

Rien ne me fait sentir plus nostalgique que de me plonger dans un bon vieux jeu NES ou Sega. Pourtant, j&rsquo;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&rsquo;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&rsquo;a frappé, c&rsquo;est son interface basée sur EmulationStation entièrement fonctionnelle et hautement personnalisable. C&rsquo;est un espace où tous vos jeux sont facilement accessibles, illustrés et organisés.</p>\n\n\n\n<p>Mais ce n&rsquo;est pas tout. RetroBat vous permet de télécharger, de mettre à jour et de configurer directement depuis l&rsquo;interface les émulateurs les plus réputés. Il n&rsquo;y a pas besoin de se perdre dans une multitude d&rsquo;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&rsquo;une carte graphique moderne qui supporte Direct3D 11.1 / OpenGL 4.4 / Vulkan.</p>\n\n\n\n<p>Une des caractéristiques que j&rsquo;apprécie le plus dans RetroBat c&rsquo;est sa portabilité. Vous pouvez l&rsquo;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&rsquo;Amiga 500, la Sega Genesis, la Nintendo 64 et la Playstation 1, jusqu&rsquo;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&rsquo;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",

De plus, il est facile à installer et à utiliser, nécessitant uniquement Python3 et quelques paramètres, comme les versions min/max d&rsquo;Android SDK.</p>\n\n\n\n<p>Parlons maintenant des différentes fonctionnalités de cet outil. Tout d&rsquo;abord, AMAnDe vérifie les <strong>permissions</strong> requises par votre application, ainsi que les <strong>bibliothèques</strong> utilisées. Il passe également en revue les fonctionnalités matérielles et logicielles, les <strong>configurations de sécurité réseau</strong> et les composants exportés et non exportés. Vous ne savez jamais ce que vous trouverez en creusant un peu plus profondément ! </p>\n\n\n\n<p>En outre, AMAnDe examine la <strong>fonctionnalité de sauvegarde</strong> de votre application, ainsi que les <strong>vulnérabilités potentielles</strong>.</p>\n\n\n\n<p>Maintenant que vous êtes convaincu de la valeur d&rsquo;AMAnDe, voici comment l&rsquo;installer et l&rsquo;utiliser.

C&rsquo;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&rsquo;améliore avec le temps ! Vous verrez alors des scores plus élevés et des idées encore meilleures au fur et à mesure que vous l&rsquo;utilisez.</p>\n\n\n\n<p>C&rsquo;est donc un outil conçu pour favoriser la créativité en mettant à l&rsquo;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&rsquo;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&rsquo;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&rsquo;outil avec le thème de réflexion désiré en anglais.

Les services Apple tels que Apple Pay, Apple Music et iCloud sont également affectés par ce mode.</p>\n\n\n\n<p>Pour activer le mode Isolement, il vous suffit d&rsquo;aller dans les paramètres de <strong>confidentialité et de sécurité</strong> sur votre iPhone, iPad ou Mac et d&rsquo;activer cette fonction.

Pour ce faire, vous devez vous assurer que seuls les sites Web et les applications de confiance sont autorisés à entrer, en les ajoutant à une liste. Sur un iPhone ou un iPad, vous pouvez le faire en accédant aux réglages de l&rsquo;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&rsquo;autorisation exclusivement les sites Web et les applications de confiance.

D&rsquo;ailleurs, je soutiens la LPO tous les ans et mon jardin est classé comme refuge LPO.</p>\n\n\n\n<p>D&rsquo;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&rsquo;oiseaux (et je ne parle pas des insultes). Passé le merle, la mésange et le pigeon, après y&rsquo;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&rsquo;une simple app d&rsquo;identification des oiseaux. Il s&rsquo;agit plutôt d&rsquo;un guide de terrain personnalisable qui couvre les espèces d&rsquo;oiseaux du monde entier. Pas besoin d&rsquo;être un expert en ornithologie pour l&rsquo;utiliser, c&rsquo;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&rsquo;application offre la possibilité <strong>d&rsquo;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&rsquo;apprentissage profond (deep learning), Merlin permet d&rsquo;identifier un oiseau à partir d&rsquo;une simple image. Des outils d&rsquo;identification permettent également de décrire l&rsquo;oiseau pour en déterminer l&rsquo;espèce.</p>\n\n\n\n<p>Merlin Bird ID propose de télécharger différentes bases de données avec plus de 40 000 espèces d&rsquo;oiseaux ainsi que pas mal de conseils d&rsquo;identification. Vous pourrez alors les parcourir et bien vérifier que ce qui a été identifié correspond bien à l&rsquo;animal que vous avez sous les yeux.</p>\n\n\n\n<p>Mais là où Merlin Bird ID m&rsquo;a vraiment impressionné, c&rsquo;est au niveau de son algo de reconnaissance de chants d&rsquo;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&rsquo;ai lancé l&rsquo;application 20 min en allant me balader dans mon jardin et voici ce que j&rsquo;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&#038;w=347&#038;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&#038;w=347&#038;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&rsquo;app a plus de 20 000 sons en base donc vous avez de quoi faire. C&rsquo;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&#8230; 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&rsquo;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&rsquo;en ajouter et de les paramétrer.

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>.

J&rsquo;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&rsquo;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>.

Il vous faudra un Linux du genre Ubuntu 18.04 LTS, Docker et le plugin Docker Compose. Ensuite, pour l&rsquo;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 !

Ce système d&rsquo;exploitation mise sur l&rsquo;universalité, en intégrant une tartine d&rsquo;environnements de bureau, comme GNOME et KDE Plasma ! En outre, cette distribution est basée sur Arch, ce qui permet d&rsquo;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&rsquo;est-à-dire qu&rsquo;il est conçu pour éviter toute modification non désirée du système. Toutefois, contrairement à d&rsquo;autres systèmes immuables, il permet quand même d&rsquo;installer des paquets système de manière classique, grâce à un système fonctionnant par couches. Ce procédé donne également la possibilité de revenir en arrière en cas de besoin, tout en gardant vos données intactes.</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=\"blendOS - An introduction (v2 &quot;Avial&quot;)\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/_OpKeqTtY1s?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 qui rend blendOS encore plus intéressant, c&rsquo;est sa compatibilité avec un grand nombre d&rsquo;applications et de gestionnaires de paquets. 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&rsquo;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.

Ça simplifiera la vie des développeurs d&rsquo;applications Android, qui pourront tester facilement leurs applications dans Android Studio comme si c&rsquo;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&rsquo;installer et utiliser des applications Web comme si c&rsquo;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&rsquo;exploitation vraiment universel qui vous permet d&rsquo;accéder à des applications et des environnements de bureau provenant de différentes distributions tout en ayant l&rsquo;assurance que le système ne souffrira de rien grâce à son système immuable.</p>\n\n\n\n<p>Bref, c&rsquo;est le turfu et <a href=\"https://blendos.co/\" target=\"_blank\" rel=\"noopener\">c&rsquo;est téléchargeable ici</a>.</p>\n",

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&rsquo;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&rsquo;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&rsquo;ajout d&rsquo;une colonne d&rsquo;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&rsquo;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&rsquo;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 &amp; semi sur les fichiers CSV.</p>\n\n\n\n<p>L&rsquo;une des fonctionnalités que j&rsquo;ai trouvé le plus sympa dans qsv c&rsquo;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&rsquo;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&rsquo;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&rsquo;autre aspect que j&rsquo;apprécie énormément dans qsv est son intégration avec d&rsquo;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&rsquo;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&rsquo;est des temps de traitement plus courts, et la possibilité d&rsquo;effectuer des tâches complexes en un clin d&rsquo;œil. </p>\n\n\n\n<p>Pour l&rsquo;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",

Parfois, il y a des demandes qui sont difficile pour certaines IA. C&rsquo;est là que ChatALL entre en scène puisque grâce à cet outil, vous allez pouvoir poser une seule fois votre question et recevoir des réponses de plusieurs bots IA, tels que Bing Chat, Baidu ERNIE, Bard, Poe, MOSS, Tongyi Qianwen, Dedao Learning Assistant, iFLYTEK SPARK, Alpaca, Vicuna, ChatGLM, Claude, Gradio ou encore HuggingChat. </p>\n\n\n\n<p>Ainsi, vous obtiendrez un panel de réponses que vous pourrez analyser d&rsquo;un seul coup d&rsquo;oeil.</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" fetchpriority=\"high\" width=\"1000\" height=\"625\" src=\"https://korben.info/app/uploads/2023/06/screenshot-1.webp\" alt=\"\" class=\"wp-image-152642\" srcset=\"https://korben.info/app/uploads/2023/06/screenshot-1.webp 1000w, https://korben.info/app/uploads/2023/06/screenshot-1-300x188.webp 300w, https://korben.info/app/uploads/2023/06/screenshot-1-768x480.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Parmi les fonctionnalités de ChatALL, il y a un mode de prompt rapide, la sauvegarde de l&rsquo;historique de chat en local, la mise en valeur de la meilleure réponse, la suppression des réponses indésirables, la possibilité d&rsquo;activer/désactiver les bots à tout moment, et la prise en charge de plusieurs langues (anglais et chinois pour l&rsquo;instant). De plus, ChatALL est compatible avec Windows, macOS et Linux.</p>\n\n\n\n<p>Alors, comment utiliser ChatALL ?

Et je trouvais que ça valait la peine de faire un petit coup d&rsquo;oeil dans le rétroviseur pour voir comment les choses ont avancé depuis mon test de l&rsquo;époque.</p>\n\n\n\n<p><strong>La mission d&rsquo;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&nbsp;et/ou a été récupéré dans des bases de données. Bases qui sont ensuite vendues à ce que l&rsquo;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&rsquo;espère qu&rsquo;à force vous avez compris ce que sont les data brokers et comment ils utilisent vos informations pour s&rsquo;engraisser sur votre dos. J&rsquo;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&rsquo;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&nbsp;inopinés ? On ne s&rsquo;en rend pas forcément compte parce que (et heureusement) les filtres antispam fonctionnent plutôt bien chez la plupart des fournisseurs, mais cela n&#8217;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&rsquo;est problématique. Rien à cacher, mais pas forcément envie non plus que tout le monde soit au courant, surtout si derrière&nbsp;c&rsquo;est juste&nbsp;pour nous faire bouffer des campagnes de&nbsp;spam marketing.</p>\n\n\n\n<p>Bref <a href=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Incogni n&rsquo;a pas commencé à dévier de son objectif</a> et nous proposer des tas d&rsquo;options diverses un peu fourre-tout. Ils sont restés concentrés sur leur&nbsp;service de&nbsp;base&nbsp;et l&rsquo;on amélioré au fil des mois et des retours d&rsquo;expériences. Notamment concernant le nombre de data brokers qu&rsquo;ils surveillent, 146 l&rsquo;an dernier pour plus de 180 aujourd&rsquo;hui. Ils ont aussi continué à prodiguer de nombreux bons conseils sur le respect de la&nbsp;vie privée, la sécurité en ligne &#8230;&nbsp;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&rsquo;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&rsquo;avez qu&rsquo;une étape à gérer </strong>et ils s&rsquo;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 &#8230; et c&rsquo;est tout ! L&rsquo;interface reste simple à prendre en main et vous pourrez y suivre l&rsquo;avancée du process en 1 coup d&rsquo;oeil.</p>\n\n\n\n<p>Eux vont ensuite&nbsp;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&rsquo;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&rsquo;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)&nbsp;forcément.</p>\n\n\n\n<p>Il faut savoir que vous pouvez faire cela par vous-mêmes &#8230; pour autant que vous trouviez au moins&nbsp;le mail des courtiers à contacter (ce qui n&rsquo;est pas toujours simple). Et même si c&rsquo;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&nbsp;sauver&nbsp;plus de 300 heures de votre temps, je vous avoue que je n&rsquo;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&rsquo;est ce qu&rsquo;il est devenu&nbsp;?</h4>\n\n\n\n<p>L&rsquo;outil avait trouvé&nbsp;90 brokers qui détenaient mes infos et 18 m&rsquo;avaient effacé au bout de seulement 4-5 jours. J&rsquo;ai ensuite laissé les choses suivre leur cours sans trop y revenir et aujourd&rsquo;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&rsquo;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,&nbsp;nous avons maintenant droit à une liste&nbsp;des suppressions « par défaut » (à droite sur l&rsquo;image, <em>suppression list entries</em>). Il s&rsquo;agit du nombre de<strong> data brokers qui&nbsp;ne collecteront, n&rsquo;échangeront ni ne stockeront plus d&rsquo;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&rsquo;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,&nbsp;comment il utilise nos infos,&nbsp;le nombre de requêtes déjà envoyées, le temps de résolution, etc. La seule chose qui manque c&rsquo;est p-e les informations que chaque broker détient sur nous (si c&rsquo;est juste le mail ou&nbsp;d&rsquo;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&rsquo;est forcément sur les premières semaines que vous verrez le plus d&rsquo;activité, le rythme de croisière actuel semble être de 5 à 10 retraits par mois, ce n&rsquo;est pas négligeable.</p>\n\n\n\n<p>Depuis mon test la plupart des sites tech d&rsquo;importance ont parlé du service de Surfshark. Cela va de Cybernews à&nbsp;PC Mag, Techradar ou plus proche de nous Next Inpact, Frandroid, Mac G &amp; 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&nbsp;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&amp;aff_id=13768\" data-type=\"link\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Il ne vous reste plus qu&rsquo;à découvrir Incogni !</a></h2>\n",

Une des fonctionnalités intéressantes de Swen, c&rsquo;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&rsquo;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&rsquo;actualité.

Puis clonez le dépôt avec </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/Cormanz/smartgpt.git &amp;&amp; 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&rsquo;aurez alors plus qu&rsquo;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&#8217;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&rsquo;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&rsquo;ai vu plus loin que les autres, c&rsquo;est en me tenant sur les épaules de géants</em>« . SmartGPT, c&rsquo;est un peu la même chose : en utilisant les connaissances et les compétences acquises grâce aux recherches précédentes, il étend l&rsquo;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&rsquo;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&rsquo;hésitez pas à partager vos découvertes et vos idées avec la communauté du projet (y&rsquo;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",

Cette combinaison propulse ainsi s5cmd à un niveau supérieur de performance, loin devant d&rsquo;autres utilitaires comme <a href=\"https://korben.info/s3cmd-tuto.html\">s3cmd</a> et <a href=\"https://aws.amazon.com/fr/cli/?tag=amazon0d16-21\" target=\"_blank\" rel=\"noopener\">aws-cli</a>. </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"890\" height=\"750\" src=\"https://korben.info/app/uploads/2023/05/usage.webp\" alt=\"\" class=\"wp-image-152574\" srcset=\"https://korben.info/app/uploads/2023/05/usage.webp 890w, https://korben.info/app/uploads/2023/05/usage-300x253.webp 300w, https://korben.info/app/uploads/2023/05/usage-768x647.webp 768w\" sizes=\"(max-width: 890px) 100vw, 890px\" /></figure></div>\n\n\n<p>En moyenne, s5cmd est 32 fois plus rapide que s3cmd et 12 fois plus rapide que aws-cli ! Vous imaginez bien que cela rend les choses beaucoup plus fluide.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-614086616\" 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 c&rsquo;est un outil qui s&rsquo;utilise en ligne de commande, vous pouvez tout à fait l&rsquo;intégrer dans vos propres process. Et si vous voulez pousser les limites encore plus loin, il existe même des scripts de tests de performance pour comparer s5cmd à d&rsquo;autres outils du marché.</p>\n\n\n\n<p>En somme, s5cmd est un outil fantastique pour tous ceux qui travaillent avec des buckets S3 et souhaitent accélérer leurs tâches de manipulation d&rsquo;objets. Il offre des fonctionnalités avancées et un niveau de performance remarquable. </p>\n\n\n\n<p>Alors, pourquoi ne pas l&rsquo;essayer ?</p>\n\n\n\n<p><a href=\"https://github.com/peak/s5cmd\" target=\"_blank\" rel=\"noopener\">À découvrir ici</a></p>\n",

Comment être sûr que ce « quelqu&rsquo;un » ne vous trahisse pas en diffusant ensuite ce document publiquement ?</p>\n\n\n\n<p>C&rsquo;est là que <strong>Wholeaked</strong> entre en jeu. Il prend le fichier que vous voulez partager et une liste de destinataires et ajoute une signature unique à chaque fichier secrètement (watermark). Ensuite, il peut envoyer automatiquement les fichiers aux destinataires correspondants en utilisant des intégrations Sendgrid, AWS SES ou SMTP. Au lieu de les envoyer par e-mail, vous pouvez également les partager manuellement. Wholeaked fonctionne avec tous les types de fichiers, mais il dispose de fonctionnalités supplémentaires pour les types de fichiers courants type PDF, DOCX, XLSX, PPTX, MOV, JPG, PNG, GIF, EPS, AI et PSD.</p>\n\n\n\n<p>Dans un monde idéal, Wholeaked serait votre poucave préférée dans la lutte contre les fuites de données. Pour identifier qui est responsable d&rsquo;une fuite, il suffit de fournir le fichier divulgué à Wholeaked, et il révèlera la personne responsable en comparant les signatures dans la base de données. C&rsquo;est comme les empreintes digitales laissées sur une scène de crime, mais dans le monde numérique !</p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-rich is-provider-prise-en-charge-des-contenus-embarques wp-block-embed-prise-en-charge-des-contenus-embarques wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"wholeaked Demonstration Video\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/EEDtXp9ngHw?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>Wholeaked utilise 3 types de signatures : binaire, métadonnées et filigrane.

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&rsquo;est là où <strong>GpuRamDrive</strong> entre en scène !</p>\n\n\n\n<p>Il s&rsquo;agit d&rsquo;un logiciel open source qui nous permet d&rsquo;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&rsquo;est comme passer d&rsquo;un vélo à une moto. Je me devais donc de partager cette trouvaille avec vous.</p>\n\n\n\n<p>Mais avant d&rsquo;aller plus loin, laissez-moi vous donner un peu de contexte sur cette technologie. Savez-vous ce que signifie le terme GPU ? Il s&rsquo;agit de l&rsquo;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&rsquo;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&rsquo;onglet « Performances », et en choisissant « GPU ». Notez votre valeur de « Mémoire dédiée » &#8211; c&rsquo;est la VRAM disponible.</p>\n\n\n\n<p>Maintenant que l&rsquo;on sait combien de mémoire nous avons à disposition, il est temps d&rsquo;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&rsquo;utiliser comme n&rsquo;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&rsquo;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&rsquo;alimentation ou de redémarrage de l&rsquo;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&rsquo;exploiter la mémoire vidéo disponible de votre carte graphique pour booster les performances de votre ordinateur.

D&rsquo;ailleurs je me suis prêté à un petit exercice que seuls les vieux peuvent se permettre de faire sur leur propre site : j&rsquo;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&rsquo;hui.</p>\n\n\n\n<p>Certaines menaces ont bien sûr disparu, d&rsquo;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&nbsp;<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&rsquo;alerte, etc.</p>\n\n\n\n<h2 class=\"wp-block-heading\">Malware,&nbsp;logiciels espions&nbsp;&amp; ransomware&nbsp;</h2>\n\n\n\n<p>On va commencer par ce qui reste sans doute l&rsquo;une des plus grandes familles de&nbsp;menaces à l&rsquo;heure actuelle. Il est bien loin le temps où vous étiez contaminé&nbsp;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>&nbsp;reçue afin de&nbsp;vous faire installer un logiciel malveillant (j&rsquo;avais prévenu, j&rsquo;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&rsquo;idée de ces infections est de contaminer votre système&nbsp;via un matériel hardware (genre clé USB), un document&nbsp;ou un téléchargement&nbsp;vérolé, de faire&nbsp;planter votre réseau et/ou de récupérer des données sensibles à votre insu. C&rsquo;est déjà pénible lorsque ça vous arrive en tant que particulier, mais ça l&rsquo;est encore plus pour une organisation. Voir c&rsquo;est carrément dangereux si vous gérez des informations très personnelles ou permettant d&rsquo;identifier des gens avec une grande précision (documents médicaux, impôts &#8230;).</p>\n\n\n\n<p>Les ransomwares&nbsp;(oui en français ont dit rançongiciels, mais &#8230; beuuurk) sont un peu comme le stade supérieur&nbsp;des malwares, sorte d&rsquo;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.&nbsp;Vous vous rappelez&nbsp;de Wannacry il y a 6 ans&nbsp;? 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&nbsp;sous-catégorie de&nbsp;la catégorie précédente, à la différence que l&rsquo;infection se fait le plus souvent via un logiciel malveillant. Vous téléchargez un outil ressemblant à l&rsquo;original, mais dans lequel un programme malicieux est incorporé. Vous pensiez&nbsp;gratter quelques euros&nbsp;en récupérant en outil payant de manière gratuite ? Bravo&nbsp;jeunes&nbsp;rebelzzz, vous avez même&nbsp;eu droit&nbsp;un petit&nbsp;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,&nbsp;ont été contaminés par&nbsp;divers virus au fil des années. Un botnet est une collection de machines ayant été infectées et formant un réseau. Ce réseau&nbsp;peut&nbsp;alors être utilisé pour envoyer des&nbsp;requêtes (et faire tomber des sites) ou des messages par milliers (par exemple des mails de phishing). Dans le cas présent la menace n&rsquo;est pas directe, mais une protection aurait pu empêcher&nbsp;ces appareils de propager&nbsp;virus et compagnie.</p>\n\n\n\n<h2 class=\"wp-block-heading\">L&rsquo;hameçonnage aka Phishing</h2>\n\n\n\n<p>Un autre type de menace assez ancienne, mais elle a pris encore plus d&rsquo;ampleur ces dernières années avec l&rsquo;arrivée des cryptos. Le domaine est particulièrement ciblé, car certains s&rsquo;y lancent sans trop savoir ce qu&rsquo;ils font et sont donc des cibles de choix&nbsp;(non Metamask ne vous contactera jamais, non Trustwallet ne vous demandera jamais votre clé privée &#8230;).</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&nbsp;du site auquel les vilains veulent avoir accès (banques, plateformes crypto/bourse &#8230;). Que ce soit en vous balançant un mail ou via une communication sur les réseaux sociaux, souvent avec un certain degré d&rsquo;urgence (« Cliquez vite sinon votre portefeuille risque d&rsquo;être bloqué pour toujouuuuurs »).&nbsp;Ou même de vous&nbsp;gruger avec un nom de domaine qui&nbsp;est écrit&nbsp;avec des&nbsp;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>).&nbsp;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&nbsp;pas mal fait parler d&rsquo;elle autour de 2018. Il s&rsquo;agissait de vous faire installer une application quelconque (sur votre&nbsp;navigateur par exemple) qui minait de la crypto (surtout du Monero) à votre insu&nbsp;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&rsquo;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&nbsp;des sites pour injecter du code malveillant. Pour résumer, il s&rsquo;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&rsquo;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&rsquo;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 ?&nbsp;(se moquer c&rsquo;est mal, sachez-le). <strong>De bons comportements sur le web et un&nbsp;bon antivirus</strong> comme celui de Surfshark (dispo pour macOS, Android et Windows). Ce dernier, qui utilise le très bon moteur d&rsquo;Avira,&nbsp;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&nbsp;dans vos&nbsp;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&nbsp;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&rsquo;avoir une grosse bécane pour le faire tourner. Son autre avantage est bien entendu d&rsquo;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&rsquo;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&rsquo;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&amp;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&rsquo;ailleurs proposé à Sega de créer gratuitement des lieux pour un futur jeu Sonic en 3D. Ainsi, l&rsquo;équipe de développement d&rsquo;un jeu pourrait travailler à partir de propositions visuelles réalistes fournies par l&rsquo;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&rsquo;est pas tout, car Sky Box est capable d&rsquo;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>.

Evidemment, les fans inconditionnels ont cherché désespérément depuis à mettre la main sur une borne d&rsquo;arcade du jeu. Mais c&rsquo;est un Graal impossible à atteindre pour le commun des mortels. Mais grâce à ce portage, c&rsquo;est de l&rsquo;histoire ancienne. Plus besoin de vendre votre âme au diable pour mettre la main sur une version borne d&rsquo;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&rsquo;on en oublierait presque qu&rsquo;il s&rsquo;agit d&rsquo;un jeu d&rsquo;arcade et non d&rsquo;un des épisodes majeurs de la série. Jusqu&rsquo;à deux joueurs peuvent jouer simultanément, incitant à la coopération et permettant de partager les frissons de l&rsquo;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&rsquo;élite et la petite sorcière. Chacun d&rsquo;eux présente ses propres compétences et armes ce qui permet d&rsquo;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&rsquo;œil aux fans de longue date. On notera également la qualité graphique et l&rsquo;ambiance sonore, toujours fidèle à l&rsquo;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&rsquo;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&rsquo;arcade d&rsquo;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&rsquo;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&rsquo;arcade en général. Si vous n&rsquo;êtes pas familier avec la série, c&rsquo;est également une excellente occasion de vous plonger dans cet univers par le biais d&rsquo;un gameplay amusant et coopératif. C&rsquo;est une cette chance de revivre les frissons des jeux d&rsquo;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&rsquo;affronter les forces du mal et de libérer le monde des griffes de l&rsquo;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&rsquo;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&rsquo;image en niveaux de gris et attribuera une hauteur en 3D en fonction de la luminosité. Je vous fais une petite analogie simple à comprendre : imaginez que chaque pixel corresponde à un monticule de sable sur une plage. 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. Le mode Extrude Color fonctionne de la même manière que le mode Standard mais intègre également les informations de couleur pour créer un modèle 3D plus réaliste et détaillé.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-656577290\" 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 vous pouvez le voir, en mode standard, c&rsquo;est tout un concept : </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"452\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230529-htce.webp\" alt=\"\" class=\"wp-image-152540\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230529-htce.webp 1000w, https://korben.info/app/uploads/2023/05/SCR-20230529-htce-300x136.webp 300w, https://korben.info/app/uploads/2023/05/SCR-20230529-htce-768x347.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Mais en mode Extrude, on peut partir d&rsquo;un simple dessin comme ceci : </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"638\" src=\"https://korben.info/app/uploads/2023/05/an-ufo-a-spacecraft-object-illustration-in-uncolored-outline-simple-hand-drawn-drawing-of-a-single-space-object-a-doodle-isolated-on-white-for-outer-space-theme-design-free-vector-1.webp\" alt=\"\" class=\"wp-image-152542\" srcset=\"https://korben.info/app/uploads/2023/05/an-ufo-a-spacecraft-object-illustration-in-uncolored-outline-simple-hand-drawn-drawing-of-a-single-space-object-a-doodle-isolated-on-white-for-outer-space-theme-design-free-vector-1.webp 1000w, https://korben.info/app/uploads/2023/05/an-ufo-a-spacecraft-object-illustration-in-uncolored-outline-simple-hand-drawn-drawing-of-a-single-space-object-a-doodle-isolated-on-white-for-outer-space-theme-design-free-vector-1-300x191.webp 300w, https://korben.info/app/uploads/2023/05/an-ufo-a-spacecraft-object-illustration-in-uncolored-outline-simple-hand-drawn-drawing-of-a-single-space-object-a-doodle-isolated-on-white-for-outer-space-theme-design-free-vector-1-768x490.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Et arriver à un vrai objet comme ceci : </p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1000\" height=\"450\" src=\"https://korben.info/app/uploads/2023/05/SCR-20230529-hutr.webp\" alt=\"\" class=\"wp-image-152543\" srcset=\"https://korben.info/app/uploads/2023/05/SCR-20230529-hutr.webp 1000w, https://korben.info/app/uploads/2023/05/SCR-20230529-hutr-300x135.webp 300w, https://korben.info/app/uploads/2023/05/SCR-20230529-hutr-768x346.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Pour les amateurs de jeux vidéo et les développeurs d&rsquo;applications 3D, cet outil est une véritable aubaine.

Tout comme <a href=\"https://korben.info/doom-retro-portage-windows.html\">Doom Retro</a>, il est basé sur l&rsquo;excellent Chocolate Doom, dont la réputation n&rsquo;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&rsquo;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&rsquo;attention. La liberté de mouvement notamment au niveau de l&rsquo;angle de vue offre une perspective de jeu beaucoup plus immersive. L&rsquo;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&rsquo;est pas chasseur, que de savoir exactement où l&rsquo;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&rsquo;encombre pas l&rsquo;écran d&rsquo;infos inutiles. Pour ne rien gâcher, une fonctionnalité de capture d&rsquo;écran vraiment clean a été ajoutée, permettant de capturer nos exploits sans les encombrer avec les éléments de l&rsquo;interface.</p>\n\n\n\n<p>Bien sûr, une longue liste d&rsquo;autres améliorations sont également de la partie, comme les chiffres de la barre d&rsquo;état qui ont été colorisés, la possibilité de marcher sur ou sous des monstres et des cadavres suspendus (brrr), ou encore l&rsquo;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&rsquo;un des atouts majeurs de Crispy Doom, selon moi, est sa capacité à offrir toutes ces améliorations sous la forme d&rsquo;options que vous êtes libres d&rsquo;activer ou non via le menu « Crispness », en ligne de commande ou grâce à l&rsquo;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&rsquo;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&rsquo;à part Doom, il existe également des portages pour d&rsquo;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&rsquo;aurait pas vu le jour. Si vous avez des bugs ou des problèmes à signaler, vous pourrez le faire via l&rsquo;<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&rsquo;est à découvrir par ici</a>.</p>\n",

Aujourd&rsquo;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&rsquo;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&rsquo;autres libs Python pour effectuer une reconnaissance faciale en temps réel.</p>\n\n\n\n<p>Pour l&rsquo;installer, assurez-vous d&rsquo;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>&#8230; fera l&rsquo;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&rsquo;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&rsquo;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&rsquo;ajuster l&rsquo;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&rsquo;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&rsquo;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&rsquo;est une bonne opportunité pour vous lancer dans la création d&rsquo;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",

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&rsquo;API Win32 (c&rsquo;est-à-dire que vous n&rsquo;avez pas besoin de Windows pour exécuter Wine), alors que MOL est une « machine virtuelle » qui vous permet théoriquement de démarrer n&rsquo;importe quel système d&rsquo;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&rsquo;exécuter sur du matériel non-Apple, comme la carte Pegasos, la carte Teron ou encore du matériel AmigaOne. En bref, MOL doit pouvoir s&rsquo;exécuter sur n&rsquo;importe quel matériel PowerPC.</p>\n\n\n\n<p>À partir de là, l&rsquo;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.

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>&#8230;indique à MOL d&rsquo;utiliser toutes les partitions HFS[+] trouvées sur /dev/hda (premier disque IDE), en autorisant l&rsquo;accès en écriture.

C&rsquo;est un outil hyper pratique qui s&rsquo;appelle <strong>Reggy</strong>. Reggy c&rsquo;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&rsquo;importe quel site sans dévoiler notre identité réelle ! </p>\n\n\n\n<p>Voilà comment fonctionne cette merveille : une fois l&rsquo;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&rsquo;aide de cette extension, vous pourrez alors vous inscrire sur n&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;oubliez pas que l&rsquo;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&rsquo;identité. Prison direct sinon !! L&rsquo;outil est surtout destiné à simplifier le processus d&rsquo;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&rsquo;ai testé et c&rsquo;est vraiment cool.</p>\n\n\n\n<p>Comme vous le savez, beaucoup d&rsquo;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&rsquo;est là qu&rsquo;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&rsquo;est complémentaire d&rsquo;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&rsquo;API chrome.debugger que Vytal utilise pour modifier les données de votre navigateur. Cela permet à l&rsquo;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&rsquo;autres extensions du marché, Vytal se distingue par sa facilité d&rsquo;utilisation et sa transparence. Pas de collecte de données en arrière-plan, pas de publicité intrusive. Tout est fait pour vous offrir l&rsquo;expérience de navigation la plus sécurisée et anonyme possible.</p>\n\n\n\n<p>Vytal fonctionne également très bien avec d&rsquo;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&rsquo;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",

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&rsquo;habitais en centre-ville de Marseille. Enfin, jusqu&rsquo;à la prochaine fois&#8230;</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&rsquo;a plus qu&rsquo;à laisser sécher ce futur bois de chauffage pendant quelques années. Vive la tronçonneuse ! Et oui j&rsquo;ai mal partout, mais j&rsquo;ai conservé mes 2 jambes. Ces activités en plein air, c&rsquo;est mieux que Basic Fit.</p>\n\n\n\n<p>Avec la fin des vacances de février, c&rsquo;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&rsquo;est l&rsquo;occasion de reprendre nos échanges passionnés ;-).</p>\n\n\n\n<p>J&rsquo;ai également commencé une série que je trouve très cool : The Orville. Même si elle n&rsquo;est pas récente, elle est très fun. C&rsquo;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&rsquo;oubliez pas de vous accrocher à vos projets et de continuer à apprendre chaque jour. J&rsquo;espère d&rsquo;ailleurs que j&rsquo;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",

Mais ce que je n&rsquo;ai pas encore abordé c&rsquo;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&rsquo;est déjà pas très fun en soit. Mais réaliser qu&rsquo;il y a en plus un risque qu&rsquo;elles se retournent contre nous pour impacter négativement notre vie, c&rsquo;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&rsquo;informations</strong> depuis de nombreuses sources (base de données revendues/hackées, profils sociaux, données publiques,&nbsp;cookies publicitaires&nbsp;&#8230;). Ils croisent alors ces différentes&nbsp;datas&nbsp;afin de&nbsp;créer&nbsp;un profil numérique le plus complet possible pour chaque internaute et les classer dans différentes catégories d&rsquo;audience (joueurs de console PlayStation, ménagère dont le hobby est la cuisine, grand sportif &#8230;). Je parie qu&rsquo;ils ont même créé une catégorie rien que pour moi : chef d&rsquo;Internet éleveur de poules ou débroussailleur poseur&nbsp;placo.</p>\n\n\n\n<p>Et quand je parle de « chaque internaute » je ne pense pas être trop&nbsp;loin de la réalité. Vous avez un compte Amazon ? À moins d&rsquo;interdire les cookies, vos infos sont revendues à plusieurs dizaines de boites. En 2022 la CNIL a généré pour plus de 100 millions d&rsquo;amendes autour du <strong>mauvais respect de la protection des&nbsp;données personnelles des Français</strong>. Et « tout le monde » y est passé : Microsoft, Apple, Facebook (quelle surprise!)&nbsp;&#8230; même EDF&nbsp;et plus récemment l&rsquo;éditeur de jeux mobiles&nbsp;Voodoo (Helix Jump, Paper.io &#8230;).</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&nbsp;notre intimité, le profil qui est&nbsp;créé&nbsp;n&rsquo;est pas forcément toujours précis ni d&rsquo;actualité. Il peut y avoir des zones d&rsquo;ombres, des données périmées,&nbsp;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&rsquo;organisme qui achète vos infos est une banque, une assurance ou encore une entreprise qui recrute.&nbsp;Et que ces derniers prennent une décision basée sur un profil qui ne représente plus&nbsp;votre situation actuelle. Aux USA, il y a déjà quelques années, un homme s&rsquo;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&rsquo;a pas été possible de prouver à 100% que tout le concernait. L&rsquo;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,&nbsp;cela peut mal tourner.&nbsp;La meilleure protection à ce niveau&nbsp;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&rsquo;est pas nécessaire</li>\n\n\n\n<li>ne pas donner plus d&rsquo;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 &#8230;)</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&nbsp;<a href=\"https://korben.info/incogni-test.html\" data-type=\"URL\" data-id=\"https://korben.info/incogni-test.html\">vers Incogni</a>.

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 &amp; Pokémon Violet – Maintenant disponibles ! (Nintendo Switch)\" width=\"800\" height=\"450\" src=\"https://www.youtube.com/embed/Xh-LDo6C_r8?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>1) Un monde tout vert</h2>\n\n\n\n<p>Ok, on commence par la promesse initiale : le monde ouvert. 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&rsquo;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&rsquo;école forbuissonnière</h2>\n\n\n\n<p>Au centre de la map : l&rsquo;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&#8230;). 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&#8230;), 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, &#8230;). <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&rsquo;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&#8230; 🙁 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&rsquo;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.&nbsp; 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&rsquo;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",

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&rsquo;électricité assez polluantes (charbon par exemple) et le gouvernement a même annoncé des coupures d&rsquo;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&rsquo;est la canicule avec un petit 19°. Donc bon, que faire ?</p>\n\n\n\n<p>Et bien l&rsquo;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&rsquo;idée est simple : <strong>décaler notre consommation d&rsquo;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&rsquo;Apple Store ou l&rsquo;Android Play Store, l&rsquo;application vous demande de vous créer un compte et de lier votre compteur Linky avec leur service. C&rsquo;est normal puisqu&rsquo;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&rsquo;app m&rsquo;avertit lorsqu&rsquo;un « effacement » est programmé. En général c&rsquo;est de 19h à 19h30, voire 20h. Les week-ends, c&rsquo;est plutôt le matin.</p>\n\n\n\n<p>J&rsquo;indique sur l&rsquo;application que je souhaite participer à cet effacement et quand vient l&rsquo;heure, je coupe ou je ne lance pas certains appareils électriques : Radiateurs, four, lave-vaisselle&#8230;etc. Et lorsque c&rsquo;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&rsquo;abord, je participe à l&rsquo;effort commun lors des pics de consommation électrique. Bruno Lemaire est fier de moi ^^ ! </p>\n\n\n\n<p>Ensuite, j&rsquo;économise de l&rsquo;argent puisque pendant 1h, mon chauffage n&rsquo;a pas tourné (et rassurez-vous, ça ne change pas grand-chose niveau confort puisqu&rsquo;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&#038;w=600&#038;ssl=1 600w,https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?strip=info&#038;w=900&#038;ssl=1 900w,https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?strip=info&#038;w=1200&#038;ssl=1 1200w,https://i2.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-1-507x1024.webp?strip=info&#038;w=1267&#038;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&#038;w=600&#038;ssl=1 600w,https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?strip=info&#038;w=900&#038;ssl=1 900w,https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?strip=info&#038;w=1200&#038;ssl=1 1200w,https://i0.wp.com/korben.info/app/uploads/2023/01/visuel-telephone-2-506x1024.webp?strip=info&#038;w=1264&#038;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&rsquo;une énergie décalée, c&rsquo;est une énergie qui ensuite n&rsquo;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&rsquo;on n&rsquo;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&rsquo;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&rsquo;autres utilisateurs coupent carrément le disjoncteur et partent faire un tour pendant 1h. Ensuite, ce que vous n&rsquo;avez pas consommé est comptabilisé dans l&rsquo;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&#8217;empreinte carbone de votre iPhone dernier cri 🙂</p>\n\n\n\n<p>Alors je vous rassure, rien n&rsquo;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&rsquo;est comme ça que fonctionnent les opérateurs d&rsquo;effacement. Ils aident le réseau électrique à effacer la crête des pics de consommation. Les marchés européens leur paye l&rsquo;électricité non consommée au même tarif qu&rsquo;une électricité consommée et Survoltage en reverse environ 60%. D&rsquo;après Survoltage, en jouant le jeu tous les jours, vous pouvez gagner jusqu&rsquo;à 15% d&rsquo;économie sur votre facture à l&rsquo;année en plus des points EWATT gagnés.</p>\n\n\n\n<p>Un truc intéressant avec Survoltage, c&rsquo;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&rsquo;air !</p>\n\n\n\n<p>Et bien sûr l&rsquo;application est totalement gratuite. Le mieux c&rsquo;est donc de l&rsquo;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&rsquo;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",

Alors bien sûr quand XGIMI m&rsquo;a proposé de tester le <a rel=\"noopener\" href=\"https://me.korben.info/xgimilink\" target=\"_blank\"><strong>HORIZON Pro</strong></a>, j&rsquo;ai évidemment accepté car j&rsquo;étais très curieux de voir toutes les évolutions qu&rsquo;il y a eu en matière de vidéo projecteur depuis toutes ces années, et je dois vous dire que je n&rsquo;ai pas été déçu. Pour info, je vous ai également mis un code promo à la fin de l&rsquo;article qui permet d&rsquo;obtenir 200 euros de réduction sur l&rsquo;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&rsquo;est « user-first », c&rsquo;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&rsquo;abord vous parler de mon expérience « projo ». J&rsquo;ai un beau mur blanc à la maison, un chouette canapé, et c&rsquo;est un grand plaisir de pouvoir voir un film « en grand, comme au cinéma ». </p>\n\n\n\n<p>J&rsquo;habite pas à côté d&rsquo;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&rsquo;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&rsquo;impossibilité de mettre en pause quand on veut faire une pause pipi&#8230; </p>\n\n\n\n<p>Vous l&rsquo;aurez compris, je suis plutôt guéri de « l&rsquo;expérience cinéma » et j&rsquo;adore mon projecteur à la maison, que j&rsquo;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&rsquo;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&rsquo;expérience. C&rsquo;est encore mieux. Ce projecteur dispose d&rsquo;un moteur optique 4K, d&rsquo;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&rsquo;avant même si j&rsquo;ai découvert à cette occasion que Netflix voulait m&rsquo;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&rsquo;est moyen. Mais avec sa luminosité de 2200 ANSI lumens, c&rsquo;est parfaitement faisable et tout aussi agréable qu&rsquo;en soirée. D&rsquo;ailleurs si vous vous demandez à quelle taille d&rsquo;écran le HORIZON Pro correspond avec sa résolution, c&rsquo;est comme si vous aviez une TV de 200 pouces de diagonales (soit 4,42 mètres sur 2,52 mètres). Gigantesque non ?</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"389\" src=\"https://korben.info/app/uploads/2023/01/SCR-20230123-efl.webp\" alt=\"\" class=\"wp-image-132383\" srcset=\"https://korben.info/app/uploads/2023/01/SCR-20230123-efl.webp 1024w, https://korben.info/app/uploads/2023/01/SCR-20230123-efl-300x114.webp 300w, https://korben.info/app/uploads/2023/01/SCR-20230123-efl-768x292.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure></div>\n\n\n<p>Vous l&rsquo;aurez compris, j&rsquo;ai été impressionné par la qualité de l&rsquo;image. J&rsquo;ai fait quelques tests avec des vidéos 4K le HDR-10 (pour un max de contrastes) et X-VUE 2.0 qui permet d&rsquo;avoir une qualité de fou en terme de rendu d&rsquo;image, avec des couleurs vives, des noirs profond et même une réduction du « bruit » présent sur l&rsquo;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&rsquo;image, réduisant la latence, faisant disparaitre les images fantômes et compensant la perte de détail sur l&rsquo;image. C&rsquo;est très sympa surtout pour les amateurs de films d&rsquo;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&rsquo;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&rsquo;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&rsquo;image, mais avec ce nouveau projecteur, c&rsquo;est un autre délire. Comme il est équipé de la technologie d&rsquo;Adaptation Intelligente de l&rsquo;Ecran (ISA), il est capable de proposer une mise au pointe entièrement automatique ainsi qu&rsquo;une correction de la distorsion trapézoïdale (si votre projo n&rsquo;est pas pile poile en face de votre mur ou que votre mur n&rsquo;est pas droit). Il dispose même d&rsquo;un mode de contournement intelligent des obstacles, ce qui permet de régler l&rsquo;affichage pour qu&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;il est très silencieux. C&rsquo;est pas une soufflerie comme d&rsquo;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&rsquo;ai pas besoin de brancher d&rsquo;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&rsquo;est de l&rsquo;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&#8230;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&rsquo;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&rsquo;un mode « jeu » avec une latence basse de 35ms et également d&rsquo;un mode « 3D » pour ceux qui veulent se repasser Avatar avec les lunettes. Enfin, en matière de connectivité, il y a tout ce qu&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;exemple ci-dessous, je vous montre également qu&rsquo;on peut chiffrer des fichiers qui seraient le résultat d&rsquo;une commande (ici une création d&rsquo;archive tar) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>tar cvz ~/data | age -r age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p &gt; 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 &gt; 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&rsquo;une phrase de passe avec le paramètre -p.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>age -p fichier.txt &gt; 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&rsquo;outil vous demandera alors de saisir une phrase de passe ou la générera pour vous. </p>\n\n\n\n<p>Vous l&rsquo;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 &gt; 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 &gt; 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",

La plupart des gens sont dans le superficiel, ce qui est normal puisque tout le monde se méfie de tout le monde, et personne n&rsquo;a le temps d&rsquo;approfondir les échanges. C&rsquo;est triste.

Évidemment déjà à l&rsquo;époque, je m&rsquo;intéressais beaucoup à la cybersécurité, mais à ma connaissance, il n&rsquo;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&#8217;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&rsquo;est aussi un terrain d&rsquo;affrontement pour les armées du monde entier.</p>\n\n\n\n<p>C&rsquo;est pour ça que j&rsquo;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&rsquo;elle a été lancée en 2017 sur l&rsquo;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&rsquo;armée en matière de cybersécurité. C&rsquo;est un peu comme si l&rsquo;armée vous disait : &nbsp;«&nbsp;<em>Vous aimez la cybersécurité ? Alors, venez nous aider à protéger notre pays !</em>&nbsp;». </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&#038;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&rsquo;agit d&rsquo;un <strong>BTS CIEL </strong>(Cybersécurité, Informatique et réseaux, Électronique, anciennement BTS SNIR) reprenant en totalité le programme officiel de l&rsquo;Éducation Nationale, sauf qu&rsquo;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&rsquo;une simple formation de 2 ans après le bac : c&rsquo;est carrément une nouvelle vie qui s&rsquo;offre à ceux qui choisiront cette voie puisqu&rsquo;un contrat d&rsquo;engagement est signé avec le Ministère. Vous serez logé (c&rsquo;est de l’internat), nourri et blanchi avec un peu d&rsquo;argent de poche et en 2 ans, vous obtiendrez un niveau opérationnel se rapprochant de celui de quelqu&rsquo;un qui aurait fait une licence. Vous l&rsquo;aurez compris, c&rsquo;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&rsquo;est ouvert à toutes les personnes de nationalité française et vous n&rsquo;avez pas nécessairement besoin d&rsquo;avoir des connaissances en informatique à l&rsquo;entrée. Il faut juste être motivé, exigeant avec soi-même et avoir une très bonne capacité de travail. Et surtout, vous l&rsquo;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&rsquo;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&rsquo;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&rsquo;une personne qui a suivi ce cursus au sein de l&rsquo;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&#038;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&rsquo;est que tout est teinté cybersécurité, y compris les cours plus traditionnels d&rsquo;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&rsquo;est une voie intéressante à envisager, avec tous les avantages d&rsquo;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>.

Pour l&rsquo;installer, clonez ce dépôt : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>git clone https://github.com/magnific0/wondershaper.git</code></pre>\n\n\n\n<p>Placez vous dedans, puis lancez la commande comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>./wondershaper -a eth0 -u 4096 -d 8192</code></pre>\n\n\n\n<p>Remplacez eth0 par le nom de votre interface réseau (ifconfig vous aidera à connaitre leurs noms). Puis spécifiez avec le paramètre -u la quantité d&rsquo;upload que vous voulez autoriser. Ici c&rsquo;est 4 Mbps. Et avec le paramètre -d, la quantité de download. Ici c&rsquo;est 8 Mbps.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1925555768\"><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 voilà.

Tout d&rsquo;abord, j&rsquo;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&rsquo;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&rsquo;est parce qu&rsquo;il faut se rendre à l&rsquo;évidence : La plupart des gens sont de grosses feignasses quand il s&rsquo;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&rsquo;à l&rsquo;école, on ne leur a jamais vraiment appris à faire preuve d&rsquo;esprit critique ou à aller au-delà de ce qu&rsquo;on peut lire. Et même si je me souviens avoir appris à décomposer un article de presse, je n&rsquo;ai jamais dans le cadre scolaire, appris à comprendre et analyser une information ou à déterminer la fiabilité d&rsquo;un relai d&rsquo;information.</p>\n\n\n\n<p>Ainsi, dans la tête de la plupart d&rsquo;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&rsquo;ils sont, et qu&rsquo;on ne va pas se transformer en debunkeur du jour au lendemain, encore moins en croisant des sources, c&rsquo;est plutôt cool qu&rsquo;on mette ce genre d&rsquo;information directement sous le nez de tout le monde.</p>\n\n\n\n<p>Je tiens d&rsquo;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&rsquo;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&rsquo;ouverture de leur bouche est inversement proportionnelle à leur ouverture d&rsquo;esprit, la vérité, c&rsquo;est qu&rsquo;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&rsquo;ai ce qu&rsquo;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&rsquo;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&rsquo;adresse mail, à l&rsquo;adresse physique en passant par vos mots de passe ou vos données bancaires. Cela dans le but de les revendre à prix d&rsquo;or à des démarcheurs ou d&rsquo;autres organismes. Selon le data broker&nbsp;cette recherche&nbsp;va aller de simplement récupérer des informations légales (que vous avez données à divers services/sites) jusqu&rsquo;à l&rsquo;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&rsquo;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&rsquo;Incogni</a>).</p>\n\n\n\n<p>Ce sont ces revendeurs&nbsp;et ces acheteurs&nbsp;qui sont entrés un peu plus dans le collimateur de la CNIL depuis début de l&rsquo;an dernier. Avec un rappel prononcé de leurs obligations en décembre 2022. Ce qu&rsquo;il faut savoir c&rsquo;est que ce genre de pratique n&rsquo;est PAS interdite par le RGPD, ce n&rsquo;est donc pas aussi simple que de dire qu&rsquo;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&rsquo;assurer de la légalité des données</strong>. Notamment qu&rsquo;elles ont bien été récoltées avec l&rsquo;accord de la personne.&nbsp;Dans la majorité des cas ce sera&nbsp;que la personne a bien validé ou coché la case des conditions générales &amp; Co lorsqu&rsquo;elle s&rsquo;est inscrite ou qu&rsquo;elle a rempli&nbsp;un formulaire. Pour ceux qui refusent ces transmissions de données dès l&rsquo;inscription, cela ne doit bien entendu&nbsp;jamais se retrouver chez un data broker, et encore moins être revendu par ce dernier.&nbsp;</p>\n\n\n\n<p>Le second point c&rsquo;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&rsquo;acte qui a généré la relation commerciale (que ce soit l&rsquo;achat sur un site e-commerce, la&nbsp;délivrance d&rsquo;une&nbsp;prestation diverse, la fin d&rsquo;une garantie&nbsp;&#8230;). De plus, tout ce qui a trait à la gestion d&rsquo;un contentieux, à la comptabilité, etc. (bref toute la paperasse administrative) doit être exclu&nbsp;par défaut&nbsp;et ne pas être partagé.</p>\n\n\n\n<p>Là où le règlement de la&nbsp;CNIL va plus loin, c&rsquo;est dans le fait que les acquéreurs des données&nbsp;doivent eux aussi s&rsquo;assurer que tout est légal. Et nous en informer (dans un délai d&rsquo;un mois), en citant leur source, si ce n&rsquo;est pas le cas.&nbsp;Nous dire à&nbsp;qui ils ont acheté nos informations en somme et nous demander notre accord. Et ça, c&rsquo;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&rsquo;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 &amp; Co. Ce genre de choses. Dans le cas inverse à lui de recueillir votre assentiment. Et si vous n&rsquo;êtes pas d&rsquo;accord, il doit respecter votre demande de retrait/modification de sa liste.</p>\n\n\n\n<p>Bref, ça, c&rsquo;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&amp;aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" target=\"_blank\">il y a Incogni</a>.</p>\n\n\n\n<p>Comme je l&rsquo;ai déjà expliqué dans d&rsquo;autres articles, le job d&rsquo;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&rsquo;auront déjà plus accès à ces informations lorsqu&rsquo;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&nbsp;5-6€/mois, le service de Surfshark est plutôt pratique. J&rsquo;ai pris quelques minutes pour mettre en place mon test et depuis ce sont des dizaines de brokers qui m&rsquo;ont retiré de leurs listes. Et qui continuerons, car l&rsquo;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&amp;aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;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&nbsp;annuel <strong>Master Dev France</strong>&nbsp;(ex meilleur Développeur de France&nbsp;qui a&nbsp;été lancé en 2013 pour la première fois),&nbsp;après&nbsp;une pause de&nbsp;2 ans, crise sanitaire&nbsp;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&nbsp;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&nbsp;allez pouvoir y&nbsp;retrouver plusieurs dizaines d’entreprises (grands groupes français, associations majeures du numérique&nbsp;…), des écoles de la tech, des éditeurs…&nbsp;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&nbsp;! Bref vous allez pouvoir mettre les mains dans le cambouis et faire un truc assez fou : discuter avec de vraies gens et leur&nbsp;poser des questions.&nbsp;</p>\n\n\n\n<p>Et en spécial bonus, <strong>Master Dev France offrira un NFT</strong> réalisé par l’artiste Léo&nbsp;Caillard&nbsp;à chaque visiteur de l&rsquo;événement ! Les visiteurs pourront collecter des&nbsp;NFTs&nbsp;auprès des partenaires de l&rsquo;événement&nbsp;via des QR codes&nbsp;disposés&nbsp;à l&rsquo;entrée et sur leurs stands.&nbsp; Partenaire de la Talent&nbsp;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&nbsp;Fair&nbsp;» de&nbsp;la Paris Blockchain Week. Une première mondiale dans le cadre d’un événement professionnel !&nbsp;</p>\n\n\n\n<p>Le programme prévoit&nbsp;<strong>une bonne&nbsp;vingtaine de conférences</strong>&nbsp;sur des sujets tech d’actualité, notamment&nbsp;le <strong>Web3</strong>&nbsp;(et l’Internet décentralisé au sens large),&nbsp;&nbsp;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&nbsp;métavers, la blockchain, le hack éthique, la cybersécurité, la régulation dans la crypto,&nbsp;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&nbsp;😉</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&nbsp;(et c’est ce qui fait battre mon petit cœur un peu plus fort), il y aura <strong>un&nbsp;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++ …).&nbsp;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)&nbsp;+ la finale qui&nbsp;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&amp;utm_source=website&amp;utm_medium=influence&amp;utm_content=korben\" target=\"_blank\" rel=\"noopener\">de vous inscrire via ce formulaire</a></strong>. Et si c&rsquo;est l&rsquo;un d&rsquo;entre vous qui l&#8217;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&nbsp;😉</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&nbsp;perçu comme un milieu où&nbsp;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&nbsp;!</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)&nbsp;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&nbsp;ça fait du bien de revoir ce genre de salons et de conférences de manière&nbsp;régulière dans un monde post-pandémie !&nbsp;Des tas de devs et de geeks vont enfin pouvoir retrouver un semblant de vie sociale, quelques jours&nbsp;chaque année&nbsp;😉</p>\n\n\n\n<p>L’évènement se tiendra le jeudi&nbsp;9 mars 2023&nbsp;au Parc des Expositions de Paris,&nbsp;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&nbsp;Master Dev France 2023 !</a></h2>\n",

Il s&rsquo;agit d&rsquo;un projet qui vous permettra de manipuler et trouver facilement toutes les vulnérabilités connues qui se cachent vos dépendances open source. </p>\n\n\n\n<p>Le projet se compose de services comme <a href=\"https://osv.dev/\" target=\"_blank\" rel=\"noopener\">ce site web</a>, une <a href=\"https://osv.dev/#use-the-api\" target=\"_blank\" rel=\"noopener\">API</a> ou <a href=\"https://osv.dev/#use-the-cli\" target=\"_blank\" rel=\"noopener\">encore des outils d&rsquo;analyses</a> capables d&rsquo;agréger, et indexer les données concernant les vulns&#8230; et également d&rsquo;une base de données ouverte utilisant un format de données dédiées aux vulnérabilités. </p>\n\n\n\n<p>Ce schéma OSV est super facile a intégrer et à utiliser et vient comme ça remédier à de nombreux problèmes liés aux vulnérabilités dans les logiciels open source. Ainsi, vous ne le savez peut-être pas, mais des bases de données de vulnérabilités comme GitHub Security Advisories, PyPA, RustSec&#8230;etc. utilisent ce schéma OSV.</p>\n\n\n\n<p>Si vous voulez voir un exemple réel de ce format JSON, <a href=\"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-9c47-m6qq-7p4h/GHSA-9c47-m6qq-7p4h.json\" target=\"_blank\" rel=\"noopener\">cliquez ici</a>.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>{\n \"schema_version\": \"1.3.0\",\n \"id\": \"GHSA-c3g4-w6cv-6v7h\",\n \"modified\": \"2022-04-01T13:56:42Z\",\n \"published\": \"2022-04-01T13:56:42Z\",\n \"aliases\": &#91; \"CVE-2022-27651\" ],\n \"summary\": \"Non-empty default inheritable capabilities for linux container in Buildah\",\n \"details\": \"A bug was found in Buildah where containers were created ...\",\n \"affected\": &#91;\n {\n \"package\": {\n \"ecosystem\": \"Go\",\n \"name\": \"github.com/containers/buildah\"\n },\n \"ranges\": &#91;\n {\n \"type\": \"SEMVER\",\n \"events\": &#91;\n {\n \"introduced\": \"0\"\n },\n {\n \"fixed\": \"1.25.0\"\n }\n ]\n }\n ]\n }\n ],\n \"references\": &#91;\n {\n \"type\": \"WEB\",\n \"url\": \"https://github.com/containers/buildah/commit/...\"\n },\n {\n \"type\": \"PACKAGE\",\n \"url\": \"https://github.com/containers/buildah\"\n }\n ]\n}</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-2025094588\"><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 installer le scanner de vulnérabilités d&rsquo;OSV, ouvrez un terminal et lancez la commande d&rsquo;install en Go suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>go install github.com/google/osv-scanner/cmd/osv-scanner@v1</code></pre>\n\n\n\n<p>Après pour scanner du code, lancez l&rsquo;outil comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>osv-scanner -r /repertoire</code></pre>\n\n\n\n<p>Vous aurez plus d&rsquo;infos <a href=\"https://github.com/google/osv-scanner\" target=\"_blank\" rel=\"noopener\">sur le scanner ici sur Github</a>.</p>\n\n\n\n<p>Bref, c&rsquo;est un projet super utile, que ce soit pour scanner vos propres projets, faire de l&rsquo;analyse ou tout simplement créer votre propre base de vulns maison, sans avoir à réinventer la roue. En rendant votre base de données disponible au format OSV, vous permettrez à d&rsquo;autres personnes de l&rsquo;utiliser, de contribuer ou mutualiser la donnée.</p>\n\n\n\n<p>Merci à Letsar pour le partage !</p>\n",

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&rsquo;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&rsquo;un fichier ou d&rsquo;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&rsquo;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&rsquo;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",

Et c&rsquo;est dommage car en tant que développeur, vous aimeriez peut être mesurer le temps d&rsquo;exécution d&rsquo;un script shell pour savoir s&rsquo;il est plus rapide qu&rsquo;une version précédente. Ou pouvoir comparer la rapidité d&rsquo;exécution de différents programmes afin de sélectionner le meilleur !</p>\n\n\n\n<p>Pas de souci, j&rsquo;ai ce qu&rsquo;il vous faut. Cela s&rsquo;appelle <a href=\"https://github.com/sharkdp/hyperfine\" target=\"_blank\" rel=\"noopener\"><strong>Hyperfine</strong></a> et c&rsquo;est un outil de benchmarking qui s&rsquo;utilise en ligne de commande et qui permet de comparer les temps d&rsquo;exécution de différents programmes.</p>\n\n\n\n<p>C&rsquo;est très utile pour mesurer par exemple les performances des programmes qui effectuent beaucoup d&rsquo;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&rsquo;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&rsquo;utiliser, vous pouvez par exemple faire un benchmark de n&rsquo;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.

Du coup pour contourner ce problème, Apple a développé l&rsquo;émulateur Rosetta, qui permet d&rsquo;exécuter les applications non compatibles (pour architecture Intel quoi&#8230;) sur cette architecture ARM. C&rsquo;est cool, mais évidemment, c&rsquo;est moins performant donc il vaut mieux choper une version native de vos outils pour Silicon.</p>\n\n\n\n<p>M&rsquo;enfin, si je vous parle de ça, c&rsquo;est parce que je passe ma vie dans le Terminal et parfois, certains outils fonctionnent mal également à cet endroit. J&rsquo;avais trouvé un moyen de lancer un terminal.app en mode de compatibilité Rosetta, mais Apple a bloqué la possibilité de dupliquer l&rsquo;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&rsquo;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&rsquo;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&rsquo;interface de commande, d&rsquo;ajouter des alias ou encore des chemins d&rsquo;accès. Si vous n&rsquo;avez pas de Shell ZSH sur votre macOS, vous pouvez l&rsquo;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&rsquo;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&rsquo;architecture utilisée par votre terminal zsh. C&rsquo;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&rsquo;avez plus qu&rsquo;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&rsquo;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&rsquo;espère que ça vous aidera.</p>\n",

Les scientifiques (et Fox Mulder) estiment que l&rsquo;astéroïde avait une taille d&rsquo;environ 40 m de diamètre et qu&rsquo;il voyageait à environ 15 km/s lors de l&rsquo;impact. Cet astéroïde est tombé dans une zone peu peuplée, ce qui a limité le nombre de victimes&#8230; 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&rsquo;ai un peu abusé avec un astéroïde de 1,5 km de large tombant sur Clermont-Ferrand, mais c&rsquo;est pour les besoins de la démo. Mais ce site donne une estimation des dégâts, des morts, le rayon de l&rsquo;impact et le compare même avec d&rsquo;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&rsquo;années. Donc ça peut être ce soir ou dans 10 millions d&rsquo;années, on ne peut pas y faire grand-chose. L&rsquo;avantage c&rsquo;est qu&rsquo;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&rsquo;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&rsquo;entre eux ont été détectés et sont étudiés à ce jour&#8230; 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",

Les zombies sont bien dégueu quand même et je comprends mieux l&rsquo;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&rsquo;ai donc vu Avatar 2. C&rsquo;était bien, mais trop long et trop d&rsquo;eau partout. Je crois que j&rsquo;en ai encore dans les poumons.</p>\n\n\n\n<p>Sinon, bah toujours en mode bricole dans la maison. J&rsquo;ai encore de l&rsquo;enduit à faire, une chatière à poser, un poêle à bois à domotiser et quelques arbres arrachés avec la tempête à débiter. C&rsquo;est du taf ! J&rsquo;ai également commencé à regarder les presses à pellets et je ne sais pas encore si c&rsquo;est un bon investissement. Si vous pratiquez la fabrication de pellets, je veux bien un retour d&rsquo;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&rsquo;expérience, surtout qu&rsquo;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.

Voici un exemple de code pour illustrer la création d&rsquo;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&rsquo;outil s&rsquo;utilise en ligne de commande, mais vous pouvez aussi lui donner un fichier de config à digérer pour qu&rsquo;il fasse exactement ce que vous voulez à partir de tous les paramètres spécifiés dans ce JSON. Comme je le disais en intro, c&rsquo;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&rsquo;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&rsquo;éditer des vidéos, d&rsquo;en créer « from scratch » à partir de couleurs et d&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;installation, cette merveille peut fonctionner sous Windows, macOS ou Linux.</p>\n\n\n\n<p>Pour l&rsquo;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&rsquo;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&rsquo;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&rsquo;édition vidéo va vous faire gagner un max de temps si vous souhaitez par exemple créer un diaporama à partir de dizaines d&rsquo;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&rsquo;utiliser simplement pour recadrer automatiquement une vidéo pour l&rsquo;avoir dans plusieurs formats, c&rsquo;est également super pratique.</p>\n\n\n\n<p><a rel=\"noopener\" href=\"https://github.com/mifi/editly\" target=\"_blank\">Bref, j&rsquo;ai trouvé ça génial et c&rsquo;est à tester ici !</a></p>\n",

Cette société qui a l&rsquo;ambition de changer le visage de la robotique en plaçant l&rsquo;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&rsquo;allais voir et la surprise a été très agréable. La société porte bien son nom, puisque lors de la présentation, Miroki n&rsquo;a pas été présenté comme un robot purement fonctionnel, mais vraiment comme un personnage avec son univers, son histoire, etc. L&rsquo;objectif étant, je pense, d&rsquo;éviter l&rsquo;effet Uncanny Valley bien connu des concepteurs de robots humanoïdes, qui est le malaise ressenti par les personnes en présence d&rsquo;entités artificielles proches de l&rsquo;apparence humaine, mais pas tout à fait identiques.</p>\n\n\n\n<p>Ce robot qui nous a donc été dévoilé s&rsquo;appelle Miroki et il a été conçu et développé en moins d&rsquo;un an (un record !!) par les ingénieurs d&rsquo;Enchanted Tools. Pour la petite histoire, Miroki vient d&rsquo;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&#039;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&rsquo;il a été ensuite réduit en esclavage par les humains, mais je vous assure qu&rsquo;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&rsquo;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&rsquo;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&rsquo;il transporte du matériel ou des médicaments d&rsquo;un endroit à un autre en fonction des besoins, mais aussi qu&rsquo;il émerveille les enfants de passage à l&rsquo;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&rsquo;ailleurs, son système de déplacement sur une boule est vraiment ingénieux et même s&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;histogramme des noms d&rsquo;hôte, l&rsquo;histogramme des types de contenu, l&rsquo;histogramme des codes d&rsquo;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&rsquo;histogramme des noms d&rsquo;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&rsquo;utiliser sur votre OS, que ce soit du Windows, du MacOS, du Linux, de l&rsquo;Android ou encore FreeBSD (les sources sont disponibles).</p>\n\n\n\n<p>Voici un exemple d&rsquo;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&rsquo;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&rsquo;est pour eux puisqu&rsquo;il peuvent dresser un profil de plus en plus précis. Et ce qui permet d&rsquo;avoir cette précision c&rsquo;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 &#8230;) et&nbsp;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&nbsp;nom, prénom, adresse &amp; Co&nbsp;se trouvent sur des sites officiels publics ? Et bien en mixant&nbsp;toutes ces sources&nbsp;on obtient un profil assez complet de qui vous êtes via&nbsp;cette méthode de l&rsquo;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&nbsp;en vente au marché noir, des fuites de données, etc. </p>\n\n\n\n<p>Korben : adolescent autour de la quarantaine,&nbsp;multiples enfants, habite l&rsquo;Élysée, achète en ligne (le plus souvent des produits écologiques et des frites surgelées), s&rsquo;inquiète de sa tension artérielle et a téléchargé l&rsquo;ebook « bien manger avec ses mains ».

Chacun va vous&nbsp;demander les informations dont il a besoin pour satisfaire son offre, mieux cibler sa publicité ou générer sa liste d&rsquo;abonnés,&nbsp;mais sans abuser non plus. Prenons l&rsquo;exemple du livre blanc au format PDF, est-ce que vous le demanderiez si le site vous demandait votre adresse physique,&nbsp;votre situation familiale&nbsp;ou autre ? Bien sûr que non, vous l&rsquo;enverriez&nbsp;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&rsquo;un blog peut avoir été hackées sans même que leurs créateurs ne soient au courant.</p>\n\n\n\n<p>D&rsquo;autres services vous disent carrément qu&rsquo;ils récolteront des données vous concernant via d&rsquo;autres sites ou applis&nbsp;sur lesquelles vous êtes présents. Mais comme personne ne lit les petits caractères et que les termes employés sont volontairement vagues &#8230; ça passe. Des exemples ? Amazon, Facebook, Instagram, Google ou Twitter. En signant chez eux, vous leur donnez le droit d&rsquo;aller chercher vos informations ailleurs (avec certaines limites et une anonymisation des données &#8230; normalement). Imaginez que vous ayez un profil tout ce qu&rsquo;il y a de plus corporate sur Facebook et que vous utilisiez Twitter pour propager des conspirations platistes ou reptiliennes&nbsp;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&rsquo;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&rsquo;entreprise dans laquelle vous travaillez et autres infos. Ce qui va leur permettre d&rsquo;affiner leur communication avec vous, voire d&rsquo;aller vous relancer directement sur le réseau. Et d&rsquo;autres sites ont pignon sur rue : Clearbit, Dropcontact, etc.</p>\n\n\n\n<p>Comme tout ce croisement d&rsquo;informations se fait souvent de manière discrète dans l&rsquo;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>.

Le service va alors analyser ces derniers et voir s&rsquo;ils disposent de ces informations que vous voulez retirer. Une fois qu&rsquo;il vous aura donné la liste de ceux-ci, il va les contacter tous pour leur demander d&rsquo;effacer toute trace de votre existence. Cela mettra parfois plusieurs semaines ou mois, mais ils vont les relancer jusqu&rsquo;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&nbsp;quelques minutes à mettre en place et ensuite c&rsquo;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&rsquo;imagine que c&rsquo;est en considérant que vos données apparaitraient chez les quasi 150 brokers qu&rsquo;ils surveillent).</p>\n\n\n\n<p>Personnellement c&rsquo;est un service que j&rsquo;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).

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&rsquo;autres)…etc.</p>\n\n\n\n<p>Attention, on est encore loin de quelque chose de finalisé. C&rsquo;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&rsquo;est qu&rsquo;il est en constante évolution. Les développeurs sont sans cesse en train de travailler sur de nouvelles fonctionnalités pour améliorer l&rsquo;expérience de jeu. </p>\n\n\n\n<p>Par exemple, ils prévoient d&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;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",

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&rsquo;accéder rapidement aux fonctionnalités que vous utilisez le plus souvent, sans avoir à naviguer dans les menus de l&rsquo;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&rsquo;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",

Même quand quelqu&rsquo;un m&rsquo;apporte une réponse, je préfère toujours vérifier ce qu&rsquo;il me dit est juste. Cela peut vous paraitre abusé, mais vous n&rsquo;imaginez pas le nombre de conneries que les gens peuvent dire avec certitude. Je vous encourage à vérifier également (et discrètement).</p>\n\n\n\n<p>Mais savoir correctement utiliser un moteur de recherche et surtout faire du tri dans les informations qui sont renvoyées, ce n&rsquo;est pas forcement simple pour tout le monde. Il faut beaucoup de pratique pour éviter les sites chelous ou les conneries de fake news que les gens adorent se repasser parce que ça les conforte dans leurs délires.</p>\n\n\n\n<p>Bien qu&rsquo;il ne soit pas parfait, Andi est peut-être le moteur de recherche du futur. C&rsquo;est un genre de chatbot capable de répondre à toutes vos questions pour peu que vous les écriviez en anglais. Hé oui.</p>\n\n\n\n<p>Il y a quelques semaine, <a href=\"https://korben.info/chatgpt-openai.html\"><strong>j&rsquo;ai d&rsquo;ailleurs écrit un article sur OpenAI</strong></a> qui a lancé un chatbot, basé sur son algo GPT-3, qui utilise de l&rsquo;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&rsquo;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&rsquo;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&rsquo;Italie ?&rsquo; &#8230;</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>&#8230;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&rsquo;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&rsquo;il m&rsquo;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&rsquo;analyse ou des réponses plus rapides et donc peut-être d&rsquo;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&#8230;</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.

En faisant ça, on peut ainsi récupérer un zip contenant toutes nos données personnelles, mais également nos tweets, nos photos envoyées et surtout nos DM.</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/2022/12/supermeme_17h7_26.webp\" alt=\"\" class=\"wp-image-131712\" width=\"586\" height=\"398\" srcset=\"https://korben.info/app/uploads/2022/12/supermeme_17h7_26.webp 1000w, https://korben.info/app/uploads/2022/12/supermeme_17h7_26-300x204.webp 300w, https://korben.info/app/uploads/2022/12/supermeme_17h7_26-768x522.webp 768w\" sizes=\"(max-width: 586px) 100vw, 586px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1199840617\"><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>Personnellement, je ne pense pas qu&rsquo;Elon Musk, aussi farfelu soit-il, mette en miette un stupide site web racheté quand même 44 milliards. 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&rsquo;une page HTML fournie dans l&rsquo;archive. Mais celle-ci présente plusieurs problèmes. Par exemple, si vous cliquez sur l&rsquo;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&rsquo;est dommage.</p>\n\n\n\n<p>Concernant les DM, même s&rsquo;ils sont présents dans l&rsquo;archive, on ne peut pas savoir qui les a envoyés puisque les noms des émetteurs ont été retirés de l&rsquo;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&#8230;</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&rsquo;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&rsquo;archive, ce parser est également capable de retrouver tous ces identifiants manquants directement depuis Twitter.com pour les réintégrer dans l&rsquo;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&rsquo;outil récupère également une liste de vos followers et de vos followings ce qui peut également servir pour d&rsquo;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",

Vous installez ntfy sur <a href=\"https://play.google.com/store/apps/details?id=io.heckel.ntfy\" target=\"_blank\" rel=\"noopener\">Android</a> (<a href=\"https://f-droid.org/en/packages/io.heckel.ntfy/\" target=\"_blank\" rel=\"noopener\">F-Droid</a>) ou <a href=\"https://apps.apple.com/us/app/ntfy/id1625396347\" target=\"_blank\" rel=\"noopener\">iOS</a> et une fois que c&rsquo;est fait, vous choisissez un « topic » qui est un genre de clé. Cette clé est publique donc créez quelque chose de random et assez long pour que personne ne puisse la deviner. Autrement, quelqu&rsquo;un pourra s&rsquo;amuser à vous envoyer des notifications. Pour l&rsquo;exemple, je vais choisir « korben1234 »</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"338\" height=\"750\" src=\"https://korben.info/app/uploads/2022/12/unnamed.webp\" alt=\"\" class=\"wp-image-131702\" srcset=\"https://korben.info/app/uploads/2022/12/unnamed.webp 338w, https://korben.info/app/uploads/2022/12/unnamed-135x300.webp 135w\" sizes=\"(max-width: 338px) 100vw, 338px\" /></figure></div>\n\n\n<p>Ensuite, il y a plus qu&rsquo;à balancer la notification via Curl comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>curl -d \"Sauvegarde terminée !! 😀\" ntfy.sh/korben1234</code></pre>\n\n\n\n<p>En Python, ça donnerait ça : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>requests.post(\"https://ntfy.sh/korben1234\",\n data=\"Sauvegarde terminée !! 😀\".encode(encoding='utf-8'))</code></pre>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1035933728\"><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>En JavaScript : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>fetch('https://ntfy.sh/korben1234', {\n method: 'POST', // PUT works too\n body: 'Sauvegarde terminée !! 😀'\n})</code></pre>\n\n\n\n<p>C&rsquo;est aussi simple que ça, avec un simple POST HTTP, vous pouvez recevoir ces petites alertes bien pratiques.</p>\n\n\n\n<p>Voici une démo en vidéo : </p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-rich is-provider-prise-en-charge-des-contenus-embarques wp-block-embed-prise-en-charge-des-contenus-embarques\"><div class=\"wp-block-embed__wrapper\">\n<div style=\"width: 640px;\" class=\"wp-video\"><!--[if lt IE 9]><script>document.createElement('video');</script><![endif]-->\n<video class=\"wp-video-shortcode\" id=\"video-131698-1\" width=\"640\" height=\"360\" preload=\"metadata\" controls=\"controls\"><source type=\"video/mp4\" src=\"https://docs.ntfy.sh/static/img/android-video-overview.mp4?_=1\" /><a href=\"https://docs.ntfy.sh/static/img/android-video-overview.mp4\">https://docs.ntfy.sh/static/img/android-video-overview.mp4</a></video></div>\n</div></figure>\n\n\n\n<p>Vous pouvez personnaliser les entêtes du message, mettre une icône, joindre une image, mettre un titre et bien d&rsquo;autres choses.</p>\n\n\n\n<p>C&rsquo;est le genre de petit service qui n&rsquo;a l&rsquo;air de rien, mais qui fait des miracles et sait rapidement se rendre indispensable. Ce qui est cool avec ntfy, c&rsquo;est que vous pouvez <a href=\"https://docs.ntfy.sh/install/\" target=\"_blank\" rel=\"noopener\">l&rsquo;héberger vous-même</a> puisque le projet est open source.

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&rsquo;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&rsquo;il y a dedans. Vous pourrez facilement identifier les fichiers que vous n&rsquo;avez pas utilisés depuis longtemps et les supprimer pour gagner de l&rsquo;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&rsquo;est vraiment pratique ! Je vous le recommande. <a href=\"https://itunes.apple.com/app/shorui/id1448111859?mt=12\" target=\"_blank\" rel=\"noopener\">Vous pouvez le télécharger ici</a>.</p>\n",

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&rsquo;on perd, on recommence à zéro. Enfin pas totalement, car on débloque quand même des éléments qui vont rester d&rsquo;une partie à l&rsquo;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&rsquo;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&rsquo;aide d&rsquo;une balance). Et puis au détour d&rsquo;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&rsquo;<a href=\"https://fr.wikipedia.org/wiki/Escape_the_room\" target=\"_blank\" rel=\"noopener\">escape room</a> pourraient être mises à l&rsquo;épreuve. Un jeu dans le jeu ? Qui lui-même est dans un jeu ?

Il a des petits défauts. L&rsquo;ambiance un peu glauque peut rebuter.

Pourtant il n&rsquo;est pas exempt de défauts, on va en parler, mais disons que le hérisson bleu n&rsquo;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&rsquo;étais loin d&rsquo;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&rsquo;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&rsquo;on souhaite dans l&rsquo;ordre qu&rsquo;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&rsquo;affronter le boss de l&rsquo;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&rsquo;histoire est simple mais sympa à suivre, les répliques sont bien écrites, on retrouve bien la personnalité de nos héros favoris, d&rsquo;ailleurs, bravo à l&rsquo;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&rsquo;expérience. Aussi, les graphismes sur la version Switch sont un peu à la ramasse, c&rsquo;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&rsquo;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&#8217;empêche que c&rsquo;est un jeu vraiment agréable, pas prise de tête, qui nous propose du fun immédiat, une très bonne durée de vie… Et d&rsquo;ailleurs, des DLCs gratuits vont sortir tout au long de l&rsquo;année avec notamment de nouveaux personnages jouables (Tails, Amy Rose&#8230; &amp; 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> &#8211; <a href=\"https://amzn.to/3GeFGoz\" target=\"_blank\" rel=\"noopener\">Playstation 4</a> &#8211; <a href=\"https://amzn.to/3ieloUf\" target=\"_blank\" rel=\"noopener\">Playstation 5</a> &#8211; <a href=\"https://amzn.to/3GdOvPw\" target=\"_blank\" rel=\"noopener\">Xbox Series S</a></h2>\n",

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&#8230; C&rsquo;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&rsquo;un vous regarde jouer par-dessus l&rsquo;épaule.</p>\n\n\n\n<p>Ce n&rsquo;est qu&rsquo;un élément parmi d&rsquo;autres qui caractérisent cette ambiance complètement barrée, baroque, <em>over the top</em> : le scénario, lui aussi, part dans toutes les directions. C&rsquo;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&rsquo;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&rsquo;action reste super lisible</figcaption></figure>\n\n\n\n<p>On reste sur une base de <em>beat&#8217;em all</em> / <em>hack&rsquo;n&rsquo;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&rsquo;armes, de démons à débloquer, ce qui fait qu&rsquo;on découvre toujours de nouvelles choses, on enchaîne les combats sans se lasser.

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&#8230;et ainsi de suite.</p>\n\n\n\n<p>Alors comment ça s&rsquo;utilise ? Et bien tout d&rsquo;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&rsquo;avez plus qu&rsquo;à choisir le service qui vous intéresse.</p>\n\n\n\n<p>C&rsquo;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",

Toujours d&rsquo;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&rsquo;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.

J&rsquo;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&rsquo;outil a aussi une bonne raison d&rsquo;exister pour d&rsquo;autres problèmes annexes que l&rsquo;on peut rencontrer au cas par cas. Moins fréquents que ceux déjà cités, mais qui existe malgré tout. C&rsquo;est le cas par exemple des arnaques au CPF, ou Compte Professionnel de Formation. Arnaques qui sont en constante augmentation depuis plusieurs années, jusqu&rsquo;à représenter presque&nbsp;45 millions d&rsquo;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&nbsp;recevait chaque année un crédit d&rsquo;heures donnant droit à suivre des formations. Sauf que depuis 2019 ce crédit d&rsquo;heures a été remplacé par de la moula, chaque travailleur&nbsp;reçoit sur&nbsp;un compte&nbsp;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&rsquo;il veut utiliser avec plus de latitude (formation en ligne, etc.). Plus de 38 millions de français reçoivent ainsi plusieurs centaines d&rsquo;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&rsquo;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&rsquo;ils vous fournissent (et à travers lequel ils vont être capable de voler vos identifiants).&nbsp;Certains allant même jusqu&rsquo;à vous suivre sur les réseaux sociaux pour vous démarcher. Et une fois que vous leur avez&nbsp;envoyé votre crédit,&nbsp;ils vont disparaitre dans la nature. En récupérant au passage&nbsp;vos informations personnelles qui pourront éventuellement leur servir également (revente à des data brokers, usurpation d&rsquo;identité, vol de mot de passe, etc.). Pas de gaspillage ma bonne dame.</p>\n\n\n\n<p>D&rsquo;ailleurs un petit rappel : vos droits à la formation n&rsquo;ont pas de limite maximale d&rsquo;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&rsquo;elle est dans les clous, reconnue et validée. Ne vous contentez pas d&rsquo;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 se produit, le service Incogni peut intervenir pour s&rsquo;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&rsquo;on ne se rend pas bien compte de qui a quoi comme donnée nous concernant. Des sociétés dont vous n&rsquo;avez jamais entendu parler se retrouvent avec vos noms, adresse, numéro de téléphone, parfois numéro de sécurité sociale&nbsp;&#8230; alors que vous n&rsquo;avez jamais donné toutes ces infos à un même site. La magie des données croisées. Il suffit d&rsquo;obtenir une base de données du service X, d&rsquo;acheter une autre d’Y, de profiter d&rsquo;un hack de la messagerie du&nbsp;réseau social Z, combiner les&nbsp;3 et pouf on un profil ultra complet. Facile ensuite de vous contacter en vous donnant une certaine impression d&rsquo;être officiel puisqu&rsquo;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&rsquo;avenir, n&rsquo;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&amp;aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Découvrir Incogni !</a></h2>\n",

On y retrouve des fonctionnalités assez classiques de recadrage, de redimensionnement&#8230;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&#8230;etc.</p>\n\n\n\n<p>L&rsquo;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&rsquo;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&rsquo;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&rsquo;avez plus qu&rsquo;à cliquer sur le bouton vert « Run » pour lancer le process.

Ça tombe bien, voici la petite dernière que j&rsquo;ai pu tester et elle va surement vous plaire. Son nom : L&rsquo;AFG01 de CHEFREE.</p>\n\n\n\n<h2>Une friteuse à air polyvalente</h2>\n\n\n\n<p>Alors je vous arrête tout de suite, rien à voir avec Xavier Niel. <strong>L&rsquo;<a href=\"https://www.amazon.fr/CHEFREE-dInt%C3%A9rieur-%C3%89lectrique-AFG01-Pr%C3%A9chauffer/dp/B0BKZNM4SC/sr_1_5?maas=maas_adg_C7D7ABCF7963E4E6C11F189EE3822130_afap_abs&amp;ref_=aa_maas&amp;tag=amazon0d16-21&amp;__mk_fr_FR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&amp;keywords=friteuse+sans+huile&amp;m=AYUC1COT3XCRR&amp;qid=1669964698&amp;qu=1-5\" target=\"_blank\" rel=\"noopener\">AFG01</a></strong> est une friteuse à air de couleur noire mesurant précisément 42,6 cm de long sur 34,3 cm de large et de 34,7 cm de haut. Elle pèse environ 6 kg et est fabriquée en acier inoxydable ce qui lui donne une belle finition et la rend évidemment résistante à la corrosion.</p>\n\n\n\n<p>Au niveau de sa contenance, elle dispose d&rsquo;une capacité de 6 litres et est dotée d&rsquo;une puissance de 1660 watts, soit largement moins qu&rsquo;un four traditionnel</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img width=\"1000\" height=\"750\" decoding=\"async\" src=\"https://me.korben.info/l3x-chefree-ultenic\" alt=\"\"/></figure></div>\n\n\n<p>C&rsquo;est donc une friteuse à air de taille moyenne qui est assez puissante pour cuire rapidement et efficacement toutes sortes d&rsquo;aliments et pas uniquement des frites. 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&rsquo;utilisation</h2>\n\n\n\n<p>J&rsquo;ai donc eu l&rsquo;occasion de tester cet appareil de chez Ultenic depuis quelques semaines, et je dois dire que je suis vraiment content des plats que j&rsquo;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&rsquo;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&rsquo;allumer mon four ou mes plaques de cuisson pour réchauffer un petit truc ou faire cuire une pognée de nuggets&#8230; </p>\n\n\n\n<p>Les accessoires inclus avec l&rsquo;AFG01 sont d&rsquo;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&rsquo;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&rsquo;ai par exemple fait des pavés de boeuf et la viande est restée saignante comme je l&rsquo;aime. Même chose avec les frites qui étaient croustillantes. Bref, on obtient le même résultat qu&rsquo;avec une friteuse à huile ou un barbecue bien chaud. Manque que l&rsquo;odeur du feu de bois&#8230; par contre, la dégoulinade d&rsquo;huile de friture ne me manque pas. Et contrairement à ce qu&rsquo;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&rsquo;énergie en moins par rapport aux méthodes de cuisson traditionnelles, ce qui n&rsquo;est pas négligeable surtout en ce moment.</p>\n\n\n\n<p>L&rsquo;AFG01 est également dotée d&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;est loin d&rsquo;être un gadget. Je l&rsquo;utilise tous les jours avec sa petite soeur la K20 et je ne pourrais plus m&rsquo;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&rsquo;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&rsquo;avais un petit bémol à apporter quand même, c&rsquo;est qu&rsquo;elle prend un peu de place et qu&rsquo;elle peut ne pas être adaptée à tous les espaces de rangement en raison de son couvercle qui s&rsquo;ouvre par le haut. C&rsquo;est à prendre en compte si vous avez une petite cuisine. Mais bon, à part ça c&rsquo;est vraiment top et une fois encore c&rsquo;est un appareil qui s&rsquo;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&rsquo;est d&rsquo;y faire cuire mon propre pain.</p>\n\n\n\n<h2>60 euros de réduction sur l&rsquo;AFG01</h2>\n\n\n\n<p>Et pour encore plus d&rsquo;économies, profitez du code promo exclusif de 30 euros, valable jusqu&rsquo;au 24 décembre, en utilisant le code <strong>AFG01KORBEN</strong>.

L&rsquo;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&rsquo;ai commencé un petit break qui va durer jusqu&rsquo;au début janvier. Ne vous inquiétez pas, comme d&rsquo;habitude, j&rsquo;ai plein d&rsquo;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&rsquo;est passé l&rsquo;année 2022 pour vous, mais pour moi, ça s&rsquo;est plutôt bien déroulé. Voici d&rsquo;ailleurs quelques « achievements » dont je suis plutôt fier. Tout d&rsquo;abord, j&rsquo;ai réussi à remettre ma coquille de noix (korben.info) sur pied malgré les difficultés économiques de l&rsquo;année dernière. Le trafic sur mon site a même plutôt augmenté, donc c&rsquo;est super cool et je retrouve beaucoup de plaisir à écrire, surtout en cette période de fêtes. C&rsquo;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&rsquo;offre également de nouvelles opportunités. J&rsquo;aime bien tourner ces petites vidéos et les gens ont l&rsquo;air de les apprécier, donc c&rsquo;est cool, je vais continuer. Ensuite, sur un plan personnel, j&rsquo;ai bien avancé dans les travaux à la maison. C&rsquo;est de plus en plus habitable même s&rsquo;il fait encore bien froid à l&rsquo;intérieur&#8230; Mais là, à part dépenser une fortune pour une isolation par l&rsquo;extérieur, je ne vois pas ce qui pourrait me sauver. J&rsquo;ai également obtenu mon permis tronçonneuse et j&rsquo;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&rsquo;était cool et pour cette année 2023 qui arrive, je n&rsquo;ai pas spécialement d&rsquo;ambitions autres que de continuer sur ma lancée, c&rsquo;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&rsquo;eau. </p>\n\n\n\n<p>Et vous, comment ça s&rsquo;est passé ?</p>\n\n\n\n<p>A très bientôt ! Et passez de bonnes fêtes de fin d&rsquo;année 🍾 !</p>\n",

Il y a les développeurs qu&rsquo;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&rsquo;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&rsquo;aurez compris, le rôle d&rsquo;un product manager est donc de faire correspondre les besoins des utilisateurs avec les attentes de la société qui l&#8217;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&rsquo;utilisation et sa valeur en termes de business.</p>\n\n\n\n<p>Cet article a été rédigé en partenariat avec&nbsp;<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&#8230; 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&rsquo;un projet se mesure sur l&rsquo;impact généré par le produit et non plus bêtement sur « Est-ce que ça a été livré ? ». On s&rsquo;éloigne donc d&rsquo;une mesure bête et méchante comme une « quantité de features » sorties pour plutôt mesurer si l&rsquo;application (ou l&rsquo;objet) a été un succès en matière d&rsquo;utilisateurs ou d&rsquo;acheteurs. C&rsquo;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&rsquo;aurez compris, un produit réussi c&rsquo;est un produit qu&rsquo;on peut faire techniquement (ce n’est pas un scoop), qui sera utilisé régulièrement par les utilisateurs et enfin, c&rsquo;est un produit qui rapporte de l&rsquo;argent ou un fort gain de temps ou d&rsquo;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&rsquo;influence sur le projet. Avec votre vue d&rsquo;ensemble, vous déciderez des priorités et des objectifs à atteindre et c&rsquo;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&rsquo;à compter les accolades dans votre code. Le product manager, avec une casquette technique, a l&rsquo;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&rsquo;amélioration du design&#8230;etc. C&rsquo;est d&rsquo;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&rsquo;est vous qui donnez le « la » et qui êtes le chef d&rsquo;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&rsquo;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&rsquo;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&#8230; Faire des choix sur la stratégie, sur la technique, sur les équipes&#8230; etc. Ces choix auront des impacts que vous devrez assumer. Bref, Product Manager, c&rsquo;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&rsquo;il n&rsquo;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&rsquo;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&rsquo;objectif c&rsquo;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&#8217;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&rsquo;entreprise, pensez à mettre en avant vos compétences de développeur dans votre candidature, pour montrer que vous avez les bases techniques pour rejoindre l&rsquo;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&rsquo;oubliez pas, l&rsquo;objectif c&rsquo;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&rsquo;est comme passer d&rsquo;un sport individuel à un sport d&rsquo;équipe : c&rsquo;est passionnant, stimulant et ça bouge tout le temps ! </p>\n\n\n\n<p>Ainsi, si vous avez envie d&rsquo;avoir une vue d&rsquo;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&rsquo;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&rsquo;un nouveau genre qui permet de faire des calculs normaux, de la conversion d&rsquo;unités, du calcul de pourcentage, du calcul de fonctions&#8230;etc.,etc. au travers d&rsquo;une interface minimaliste et simple au possible. Elle permet ainsi de décrire des tâches de manière naturelle et d&rsquo;obtenir instantanément une réponse précise. Par exemple, « 20 $ en euros &#8211; remise de 5 % » ou « aujourd&rsquo;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&rsquo;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&rsquo;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&rsquo;heure actuelle pour un lieu spécifié. Les résultats sont toujours synchronisés avec l&rsquo;heure mondiale, donc en tout temps vous obtiendrez l&rsquo;heure exacte. Il est également possible de convertir une heure ou une date spécifique d&rsquo;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&rsquo;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&rsquo;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&rsquo;ajout ou la soustraction d&rsquo;un pourcentage d&rsquo;une valeur ($10 &#8211; 40%), vous pouvez également utiliser des opérations supplémentaires : pourcentage d&rsquo;une valeur, ajout de pourcentage, soustraction de pourcentage, pourcentage d&rsquo;une valeur par rapport à une autre, ajout de pourcentage d&rsquo;une valeur par rapport à une autre, soustraction de pourcentage d&rsquo;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&rsquo;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",

Surtout qu&rsquo;il y a encore en&nbsp;ce moment une petite promotion assez intéressante.</p>\n\n\n\n<p>C&rsquo;est d&rsquo;ailleurs par ça que je vais&nbsp;démarrer aujourd&rsquo;hui, histoire de commencer l&rsquo;article du bon pied. <strong><a href=\"https://get.surfshark.net/aff_c?offer_id=1066&amp;aff_id=13768&amp;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)&nbsp;pour 26 mois de protection, et cela <strong>sur un nombre illimité d&rsquo;appareils</strong> ! Difficile de faire mieux, pas encore d&rsquo;inflation chez Surfshark 😉 Et comme toujours vous pouvez encore&nbsp;ajouter une couche de sécu supplémentaire&nbsp;avec le combo alertes +&nbsp;moteur de recherche + l&rsquo;<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&amp;aff_id=13768&amp;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&rsquo;est le VPN que j&rsquo;utilise personnellement et ce que j&rsquo;apprécie c&rsquo;est que depuis leur lancement (en 2018) ils évoluent sans cesse et plutôt vite. Il y a un mois c&rsquo;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&rsquo;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&rsquo;option CleanWeb de base permet de bloquer les publicités et de vous protéger contre les malwares et autres tentatives de phishing. Avec la nouvelle&nbsp;mouture 2.0 les possibilités sont bien supérieures.&nbsp;Cette version n&rsquo;est pour l&rsquo;instant&nbsp;disponible&nbsp;que&nbsp;via&nbsp;les extensions pour navigateurs Firefox, Chrome&nbsp;et Edge. Donc sur Firefox. Les autres n&rsquo;existant pas (bouh j&rsquo;ai fais un troll sur mon site&nbsp;: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&rsquo;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&amp;aff_id=13768&amp;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,&nbsp;elle dispose d&rsquo;une personnalisation et d&rsquo;un affinage des blocages pour chacun&nbsp;site visité,&nbsp;etc.&nbsp;Cet affinage se fait sur 4 aspects (tous activés par défaut, mais&nbsp;modulable dans les paramètres)&nbsp;:</p>\n\n\n\n<ul>\n<li>le <strong>bloqueur de pubs</strong> : ne se limite plus seulement&nbsp;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&rsquo;est possible, sinon accepter uniquement&nbsp;les cookies&nbsp;obligatoires.</li>\n</ul>\n\n\n\n<ul>\n<li>les <strong>alertes malwares</strong> : vous prévient en cas de téléchargement&nbsp;risqué ou d&rsquo;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&nbsp;des soucis par le passé. Et si c&rsquo;est le cas, il vous fournit un tas d&rsquo;informations :&nbsp;à quelle date,&nbsp;de quelle nature, le nombre de comptes concernés, etc. Pratique, car si l&rsquo;un de ces sites&nbsp;à déjà plusieurs fuites&nbsp;à son actif, peut-être que cela vous fera réfléchir avant d&rsquo;y laisser vos données personnelles. Ou bien la passoire qu&rsquo;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&rsquo;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&amp;aff_id=13768&amp;source=fixed-av1\" target=\"_blank\" rel=\"noopener\">Surfshark</a> a décidé de lui donner une vraie place dans son interface avec&nbsp;une section dédiée sur&nbsp;le tableau de bord (c&rsquo;était inclus dans la section VPN auparavant). D&rsquo;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&nbsp;votre navigateur (et que l&rsquo;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&rsquo;en profite pour vous rappeler que si vous n&rsquo;êtes pas très chaud pour payer par carte bancaire ou Paypal, le site propose aussi les paiements Google Pay/Amazon Pay et même celui&nbsp;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&amp;aff_id=13768&amp;source=fixed-av1\" data-type=\"URL\" data-id=\"https://get.surfshark.net/aff_c?offer_id=1066&amp;aff_id=13768&amp;source=fixed-av1\" target=\"_blank\" rel=\"noreferrer noopener\">Profitez de l&rsquo;offre hivernale à -84% + 2 mois gratuit</a></h2>\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. Les clés seront à renseigner dans le fichier config.json.</p>\n\n\n\n<p>Concernant l&rsquo;API HackerTarget, pas d&rsquo;obligation puisque vous pouvez utiliser l&rsquo;offre gratuite limitée à quelques requêtes en utilisant l&rsquo;option « -F ». Concernant l&rsquo;<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&rsquo;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&rsquo;outil lancé, vous n&rsquo;avez plus qu&rsquo;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",

Oui, j&rsquo;ai bien dit « sans énoncé », ce qui peut, je vous l’avoue être assez perturbant.&nbsp;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&rsquo;un aigle et sa logique implacable pour trouver la solution en se basant évidemment sur le texte et l&rsquo;image. Le livre comporte 75 énigmes en tout, et certaines d&rsquo;entre elles font référence à d&rsquo;autres pages du livre ou <a href=\"https://www.laclef.online/concept/\" target=\"_blank\" rel=\"noopener\">même à des sites internet</a>.&nbsp;Vous imaginez le délire ?</p>\n\n\n\n<p>Un Discord est également disponible pour ceux qui souhaitent discuter des énigmes avec d&rsquo;autres lecteurs et avoir un petit coup de pouce.</p>\n\n\n\n<p>L&rsquo;un des aspects les plus intéressants du livre « La Clef », c&rsquo;est l&rsquo;utilisation de l&rsquo;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&rsquo;énigme et ajoutent un niveau à la complexité et à l&rsquo;originalité des énigmes. Je vous promets que ça rend l&rsquo;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&rsquo;Astolie en résolvant les énigmes.&nbsp;</p>\n\n\n\n<p>Chaque énigme est plus originale que la précédente, et certaines font même référence à d&rsquo;autres oeuvres de la littérature, du cinéma ou des jeux vidéo. Cela permet aux fans d&rsquo;énigmes de retrouver des références qu&rsquo;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&rsquo;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&rsquo;énigmes expérimentés ou les gens à l&rsquo;esprit acéré, cherchant un défi stimulant et original. Je sais, chacun d&rsquo;entre nous pense qu&rsquo;il a l&rsquo;esprit vif et qu&rsquo;il est plus malin que son voisin&#8230; 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&rsquo;univers fantastique ou de Fantasy apprécieront également la qualité des illustrations et l&rsquo;ambiance immersive créée par Fanelia. D’ailleurs, si vous appréciez ses dessins, sachez qu&rsquo;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&rsquo;être lu par les amateurs d&rsquo;énigmes et d&rsquo;univers fantastiques n’ayant pas peur de se prendre un peu la tête. Tout est qualitatif dans ce livre et les énigmes + l&rsquo;utilisation de l&rsquo;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&rsquo;univers d&rsquo;Astolie en feront un cadeau idéal pour vos amis ou votre famille, en particulier à l&rsquo;approche de Noël.&nbsp;</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",

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&nbsp;ou petit site e-commerce,&nbsp;pas une semaine ne passe sans que&nbsp;l&rsquo;un de ces&nbsp;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&rsquo;est flou ou vous l&rsquo;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&rsquo;avez encore jamais interagi avec ces services ? Combien de temps avant de recevoir des mails de phishing Metamask &amp; 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&nbsp;&#8230; est&nbsp;lié à un&nbsp;centre d&rsquo;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&rsquo;est leur gagne-pain. Et il faut déjà commencer par les identifier, ce qui n&rsquo;est pas&nbsp;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&amp;aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;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&rsquo;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&rsquo;instant plus de 145 brokers sont surveillés et la liste s&rsquo;allonge chaque mois (ils n&rsquo;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&rsquo;à ce que ce soit fait. Et même lorsque c&rsquo;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&rsquo;imagine que c&rsquo;est dans le cas où vous seriez présent sur tous les data brokers qu&rsquo;ils surveillent et je ne peux pas vérifier cette info, mais quand même. Cela en fait du temps gagné et vous suivrez l&rsquo;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&rsquo;elles en font,&nbsp;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&rsquo;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&rsquo;est pas qu&rsquo;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&rsquo;ayez pas à recommencer le travail tous les x mois. Comparé à d&rsquo;autres outils du même genre les tarifs sont plutôt bas puisqu&rsquo;ils sont de l&rsquo;ordre de moins de 5.8€/mois sur l&rsquo;abonnement à l&rsquo;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.&nbsp;Profitez d&rsquo;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&rsquo;au 4 décembre&nbsp;alors ne tardez pas&nbsp;!</p>\n</blockquote>\n\n\n\n<p>Si vous avez comme plan de disparaitre virtuellement bientôt, c&rsquo;est peut-être un outil qui vous rendra quelques services 😉 Enfin si vous habitez en Europe (inclus l&rsquo;Angleterre), aux USA, en Suisse&nbsp;ou&nbsp;au Canada. Pour les autres pays, ce n&rsquo;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&amp;aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768\" target=\"_blank\" rel=\"noreferrer noopener\">Incogni, efface-moi d&rsquo;Internet stp !</a></h2>\n",

Je pense notamment à tous les e-commerçants ou les startups naissantes qui n&rsquo;ont pas encore les moyens des grosses entreprises.</p>\n\n\n\n<p>C&rsquo;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&rsquo;offre StartUP Free</strong></a> est donc un bon moyen de découvrir les possibilités de la plateforme de 3CX sans débourser un centime.

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&rsquo;interface est vraiment très propre et très claire.

Vous pourrez par exemple proposer une interaction via <strong>WhatsApp</strong> à vos clients, simplement avec l&rsquo;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&rsquo;importe quel site web notamment <strong>WordPress</strong>, à l&rsquo;aide d&rsquo;un plugin très simple à configurer.

Cela vous permettra d&rsquo;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&rsquo;est plutôt génial d&rsquo;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&rsquo;outil est simple à prendre en main, même pour le néophyte et chacun peut alors bénéficier d&rsquo;un standard VoIP gratuitement. Les visioconférences et les appels téléphoniques sont parfaitement fluides et d&rsquo;un bon niveau de qualité, mais surtout, ce qui fait la force de 3CX c&rsquo;est vraiment l&rsquo;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&rsquo;attente et les temps d&rsquo;échange.</p>\n\n\n\n<p>Bref, c&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;est là qu&rsquo;arrive à la rescousse Firemin, un utilitaire gratuit qui est capable de libérer la mémoire non utilisée de Firefox. Alors c&rsquo;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&rsquo;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&rsquo;est sympa, c&rsquo;est que vous pouvez lui indiquer d&rsquo;autres navigateurs (Chrome, Brave, Edge&#8230;etc.) en cliquant simplement sur le bouton « Parcourir ». J&rsquo;imagine que ça peut fonctionner également avec d&rsquo;autres applications qui ne sont pas des navigateurs, donc à essayer sur vos applications consommatrices de mémoire.</p>\n\n\n\n<p>L&rsquo;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&rsquo;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&rsquo;outils, c&rsquo;est un peu comme l&rsquo;homéopathie, donc à vous de l&rsquo;essayer et de voir si vous voyez une amélioration ou pas.

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&rsquo;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&rsquo;accès internet. Bon courage avec cette dernière étape.</p>\n",

Ou en français, un courtier en données ?&nbsp;Pas vraiment&nbsp;? Pourtant je suis presque certain que vous en avez forcément rencontré un dans votre vie sur Internet, voire plusieurs. Ils pullulent tellement qu&rsquo;il&nbsp;est aujourd&rsquo;hui presque impossible de conserver son existence en ligne pour soi. Vos informations sont récupérées et exploitées chez eux.&nbsp;Malheureusement, malgré les dangers qu&rsquo;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&rsquo;internautes. Ils compilent leurs différentes sources pour créer un profil plus ou moins précis de vous en recoupant ce qu&rsquo;ils trouvent. Cela va de votre email, à votre adresse, vos noms et prénoms, vos possessions, vos informations légales&nbsp;&#8230; voir vos habitudes d&rsquo;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 &#8230;) ou partagé publiquement par vous-mêmes (réseaux sociaux &#8230;). Ensuite parce que certains services peu scrupuleux&nbsp;sur lesquels vous vous inscrivez n&rsquo;hésitent pas à les&nbsp;revendre (par exemple votre numéro de carte bancaire que vous avez&nbsp;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&nbsp;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&rsquo;ils ont recoupé et centralisé toutes leurs sources, ils vont établir des profils thématisés&nbsp;et revendre à leur tour ces informations à des entités commerciales. Vous venez de divorcer ? Vous allez subitement recevoir de la pub en rapport.&nbsp;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&rsquo;est pénible, mais en plus&nbsp;cela peut être dangereux. Certains sites web centralisent les infos et n&rsquo;hésitent pas à&nbsp;les rendre accessibles à tous. Il suffit alors d&rsquo;une recherche sur votre nom pour connaitre éventuellement votre adresse physique, l&rsquo;endroit ou vous travaillez, quelle voiture vous conduisez, si vous possédez une assurance vie ou non, qui sont les membres de votre famille, etc.&nbsp;Heureusement pour cet aspect « porte ouverte au grand&nbsp;public »&nbsp;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&rsquo;est flippant.</p>\n\n\n\n<p>Du coup l&rsquo;idéal c&rsquo;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&rsquo;un courtier détient vos infos ? Enfin, comment lui faire supprimer&nbsp;ce qu&rsquo;il possède sur vous&nbsp;?</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&amp;aff_id=13768\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;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&nbsp;les brokers qui disposent de vos&nbsp;infos personnelles</li>\n\n\n\n<li>contacter&nbsp;ces courtiers&nbsp;pour leur demander de les supprimer (ce qui est votre droit)</li>\n\n\n\n<li>relancer ces derniers s&rsquo;ils ne se bougent pas assez vite</li>\n\n\n\n<li>effectuer un suivit au fil du temps pour s&rsquo;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&rsquo;avais été plutôt étonné de voir le nombre de courtiers qui m&rsquo;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&rsquo;énervement lorsque les data brokers ignorerons vos mails. Non, mais qui êtes-vous pour leur retirer le pain de la bouche aussi ? L&rsquo;autre gros avantage du service est de vous présenter un suivit via un tableau de bord très simple à prendre en main. Vous&nbsp;verrez combien de brokers ont vos infos et suivrez en temps réel l&rsquo;avancée du&nbsp;retrait de vos données.&nbsp;Ainsi que&nbsp;le travail de sape d&rsquo;Incogni pour les relancer sans cesse jusqu&rsquo;à ce qu&rsquo;ils obtempèrent.</p>\n\n\n\n<p>Une corde de plus à l&rsquo;arc du respect de la vie privée sur Internet. C&rsquo;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&nbsp;de tranquillité d&rsquo;esprit ! Protégez vos données personnelles&nbsp;et profitez d&rsquo;une réduction de 60 % sur l&rsquo;abonnement d&rsquo;un an à Incogni.

Si vous ne connaissez pas le concept de Serverless, et bien ça va être vite résumé : C&rsquo;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&rsquo;on connait par coeur. Toutefois, c&rsquo;est dommage de ne pas continuer à découvrir de nouvelles pratiques ou technologies, car si demain. C&rsquo;est important si vous souhaitez évoluer dans la carrière de vos rêves.</p>\n\n\n\n<p>C&rsquo;est d&rsquo;ailleurs pour ça que le <a rel=\"noopener\" href=\"https://www.talent.io/p/fr-fr/talent-club?utm_source=korben&amp;utm_medium=partnership&amp;utm_campaign=Q4&amp;utm_content=article\" target=\"_blank\"><strong>talent club</strong></a> a été crée. Il s&rsquo;agit d&rsquo;une communauté tech propulsée par talent.io qui donne accès à du contenu exclusif pour vous accompagner professionnellement. En vous inscrivant (<strong>c&rsquo;est gratuit !!</strong>), vous recevrez tous les 15 jours des conseils d&rsquo;expert(e)s de sociétés comme Google, Deezer, Sorabe&#8230;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&nbsp;<a rel=\"noopener\" href=\"https://www.talent.io/p/fr-fr/talent-club?utm_source=korben&amp;utm_medium=partnership&amp;utm_campaign=Q4&amp;utm_content=article\" target=\"_blank\">talent.io</a>&nbsp;et à d&rsquo;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&amp;utm_medium=partnership&amp;utm_campaign=Q4&amp;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&rsquo;ensemble des 40 000 inscrits, de manière anonyme. <a href=\"https://www.talent.io/p/fr-fr/talent-club?utm_source=korben&amp;utm_medium=partnership&amp;utm_campaign=Q4&amp;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&#8230;</p>\n\n\n\n<p>Le serverless, ça permet d&rsquo;éviter cela et donc de réduire les coûts opérationnels, aussi bien en termes d&rsquo;hébergement, que de maintenance&#8230;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&rsquo;échelle pour absorber le trafic) très simplement.?</p>\n\n\n\n<p>Ce qui est rigolo avec ce concept de serverless, c&rsquo;est que vous pouvez y mettre toute votre application web par exemple ou simplement quelques fonctions critiques. Et c&rsquo;est cela dont on va parler aujourd&rsquo;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&rsquo;exécuter du code pour n&rsquo;importe quel type d&rsquo;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&rsquo;est pas exécuté, vous n&rsquo;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&rsquo;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&#8230;etc. Mais pas PHP, en tout cas, pas avec les outils fournis au niveau de la console d&rsquo;administration d&rsquo;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&rsquo;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&rsquo;est top pour des jobs cron, des API ou des petits sites web dont les assets sont servis par Amazon S3. Par contre pour des applications complètes en PHP, ce sera un peu plus complexe.</p>\n\n\n\n<h2>On passe à l&rsquo;installation</h2>\n\n\n\n<p>Première étape : <a href=\"https://getcomposer.org/download/\" target=\"_blank\" rel=\"noopener\">Installer Composer</a> sur votre machine.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>brew install composer</code></pre>\n\n\n\n<p>Vous allez également <a href=\"https://radixweb.com/blog/installing-npm-and-nodejs-on-windows-and-mac\" target=\"_blank\" rel=\"noopener\">avoir besoin de npm</a> : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>brew install npm</code></pre>\n\n\n\n<p>Ensuite, vous allez devoir installer le framework Serverless dont Bref a besoin pour fonctionner. Cela lui permet d&rsquo;assurer la connexion avec AWS.</p>\n\n\n\n<pre class=\"wp-block-code\"><code>npm install -g serverless</code></pre>\n\n\n\n<h2>Droits utilisateur AWS</h2>\n\n\n\n<p>Côté AWS, vous allez avoir besoin de clés d&rsquo;accès. <a rel=\"noopener\" href=\"https://console.aws.amazon.com/iam/?tag=amazon0d16-21\" target=\"_blank\">Ça se passe par ici</a>. Allez dans la section « Utilisateurs » et ajoutez un utilisateur.</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-df0.webp\" alt=\"\" class=\"wp-image-131407\" width=\"492\" height=\"453\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221114-df0.webp 833w, https://korben.info/app/uploads/2022/11/SCR-20221114-df0-300x277.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221114-df0-768x708.webp 768w\" sizes=\"(max-width: 492px) 100vw, 492px\" /></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-20221114-dfu.webp\" alt=\"\" class=\"wp-image-131408\" width=\"670\" height=\"369\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221114-dfu.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221114-dfu-300x166.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221114-dfu-768x424.webp 768w\" sizes=\"(max-width: 670px) 100vw, 670px\" /></figure></div>\n\n\n<p>Vous obtiendrez alors <a href=\"https://docs.aws.amazon.com/powershell/latest/userguide/pstools-appendix-sign-up.html?tag=amazon0d16-21\" target=\"_blank\" rel=\"noopener\">un ID de clé d&rsquo;accès et une clé d&rsquo;accès secrète</a> à bien sûr garder dans un lieu sûr comme son nom l&rsquo;indique.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"379\" src=\"https://korben.info/app/uploads/2022/11/SCR-20221114-dhn.webp\" alt=\"\" class=\"wp-image-131409\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221114-dhn.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221114-dhn-300x111.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221114-dhn-768x284.webp 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Concernant les droits à donner à votre utilisateur pour que tout se déroule correctement, voici ce que moi j&rsquo;ai mis : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>{\n \"Version\": \"2012-10-17\",\n \"Statement\": &#91;\n {\n \"Sid\": \"VisualEditor0\",\n \"Effect\": \"Allow\",\n \"Action\": &#91;\n <strong>\"iam:*\",\n \"apigateway:*\",\n \"logs:*\",\n \"lambda:*\",\n \"cloudformation:*\",\n \"s3-object-lambda:*\"</strong>\n ],\n \"Resource\": \"*\"\n }\n ]\n}</code></pre>\n\n\n\n<p>Je pense qu&rsquo;on peut affiner tout ça histoire de réduire la surface des permissions, mais ça, je vous laisse expérimenter de votre côté.</p>\n\n\n\n<p>Vous allez ensuite lier votre accès AWS avec l&rsquo;application serverless comme ceci. :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>serverless config credentials --provider aws --key <strong>VOTRECLÉAWS</strong> --secret <strong>LESECRETAWS</strong></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/2022/11/SCR-20221114-dny.webp\" alt=\"\" class=\"wp-image-131411\" width=\"810\" height=\"83\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221114-dny.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221114-dny-300x31.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221114-dny-768x79.webp 768w\" sizes=\"(max-width: 810px) 100vw, 810px\" /></figure></div>\n\n\n<h2>Création de la fonction PHP</h2>\n\n\n\n<p>Pour créer notre fonction, on va lui faire un petit nid douillet comme ceci : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>mkdir lambda\ncd lambda</code></pre>\n\n\n\n<p>Puis on lance composer afin d&rsquo;installer le framework Bref</p>\n\n\n\n<pre class=\"wp-block-code\"><code>composer require bref/bref</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/2022/11/SCR-20221114-dpo.webp\" alt=\"\" class=\"wp-image-131406\" width=\"692\" height=\"452\" srcset=\"https://korben.info/app/uploads/2022/11/SCR-20221114-dpo.webp 1024w, https://korben.info/app/uploads/2022/11/SCR-20221114-dpo-300x196.webp 300w, https://korben.info/app/uploads/2022/11/SCR-20221114-dpo-768x503.webp 768w\" sizes=\"(max-width: 692px) 100vw, 692px\" /></figure></div>\n\n\n<p>Après, il faudra initialiser le projet avec la commande suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>vendor/bin/bref init</code></pre>\n\n\n\n<p>Et là, on nous demande quel type de code lambda on souhaite créer.

On y retrouve la région AWS, le plugin utilisé&#8230;etc. :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>service: app\n\nprovider:\n name: aws\n region: us-east-1\n runtime: provided.al2\n\nplugins:\n - ./vendor/bref/bref\n\nfunctions:\n api:\n handler: index.php\n description: ''\n timeout: 28 # in seconds (API Gateway has a timeout of 29 seconds)\n layers:\n - ${bref:layer.php-81-fpm}\n events:\n - httpApi: '*'\n\n# Exclude files from deployment\npackage:\n patterns:\n - '!node_modules/**'\n - '!tests/**'\n</code></pre>\n\n\n\n<p>Maintenant, le truc rigolo, ça va être de coder un petit truc qui sera renvoyé par notre fonction exécutée dans Lambda.

Pour intégrer leur musique, j&rsquo;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&rsquo;en sers pour écouter ma musique copyrightée toute la journée donc je ne pouvais pas le dédier à ça. J&rsquo;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&rsquo;était cool et ça fonctionnait bien. Jusqu&rsquo;au jour où Chillhop (ou YouTube) a bloqué l&rsquo;autoplay sur ses Lives.</p>\n\n\n\n<p>Plus de musique de fond sur mes streams. J&rsquo;étais tristesse. Puis au bout d&rsquo;un moment, mes millions de viewers ont commencé à me réclamer de la musique en fond sonore.</p>\n\n\n\n<p>N&rsquo;écoutant que mon abnégation à leur égard, j&rsquo;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&rsquo;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&rsquo;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&rsquo;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&rsquo;ai jamais réussi à la faire fonctionner correctement. Donc je suis parti sur VLC, mais chargé à l&rsquo;extérieur d&rsquo;OBS.</p>\n\n\n\n<p>Sauf que je n’ai pas besoin de la vidéo, mais uniquement du son.

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&rsquo;est là que j&rsquo;ai appris l&rsquo;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&rsquo;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&rsquo;ai donc pondu ce script en LUA pour appeler ma ligne de commande VLC. Vous allez voir, c&rsquo;est plusieurs centaines de lignes de code ultra complexes. Non, je déconne, c&rsquo;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&rsquo;ai sauvegardé ce script en le nommant chillhop.lua, puis je me suis rendu dans OBS, menu « Tools » &gt; « Scripts » et j&rsquo;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&rsquo;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&rsquo;application. J&rsquo;ai donc rajouté un petit &amp; à la fin de la commande pour que OBS reprenne immédiatement la main et n&rsquo;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>&amp;</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&rsquo;adresse localhost. C&rsquo;est transparent et rapide.</p>\n\n\n\n<p>Ce qui est cool avec tout ça, c&rsquo;est que ça ouvre un monde de possibilité pour augmenter et piloter OBS tout en script. C&rsquo;est donc à creuser. Il ne me manque plus que les bonnes idées maintenant.</p>\n",

Mais si c&rsquo;est le cas, c&rsquo;est qu&rsquo;il y a de nombreuses bonnes raisons de le faire. Régulièrement cités <strong>parmi les services VPN les plus&nbsp;fiables</strong>, ils sont aussi&nbsp;plutôt novateurs et proposent des options qui deviennent régulièrement des standards.&nbsp;L&rsquo;une des dernières en date étant <strong>l&rsquo;innovation Nexus</strong>.</p>\n\n\n\n<p>Exclusivité Surfshark, <strong>Nexus</strong> permet de connecter l&rsquo;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&rsquo;être connecté à un serveur unique dont les performances vont&nbsp;être dégradées s&rsquo;il est surchargé. Par effet cascade le second avantage est donc d&rsquo;améliorer&nbsp;votre confidentialité. Puisque les informations transitent via plusieurs serveurs, cela fragmente la&nbsp;surveillance possible et renforce donc votre protection. Cette nouveauté sera déployée totalement d&rsquo;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 &#8230;)</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&rsquo;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&rsquo;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&rsquo;autres nouveautés sont encore prévues dans les prochains mois, parce qu&rsquo;on peut toujours faire mieux. Comme par exemple la <strong>génération automatique d&rsquo;une nouvelle adresse IP</strong> pour chaque site que vous visitez (sans devoir déconnecter/reconnecter l&rsquo;outil).&nbsp;Si la&nbsp;<strong>fonction MultiHop</strong> est déjà disponible (elle permet de mettre un serveur supplémentaire entre vous et le&nbsp;site auquel vous vous connectez), elle&nbsp;disposera bientôt d&rsquo;une option pour l&rsquo;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 ?

Pour 26 mois cela ne vous reviendra même pas à&nbsp;54€ au total, hors TVA, soit 84% de rabais. Ce qui fait toujours&nbsp;bien plaisir&nbsp;en pleine période d&rsquo;inflation. Un prix quasi&nbsp;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&rsquo;avions ou de trains, d&rsquo;un service de location &#8230; sont parfois dépendants de votre lieu de connexion. Avec Surfshark il suffit de tester depuis différents&nbsp;pays&nbsp;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&rsquo;abonnement&nbsp;avec plusieurs membres de la famille puisque le nombre d&rsquo;appareils supportés est illimité ! Votre enfant n&rsquo;a que 8 ans ? Pas d&rsquo;excuses, il faut lui apprendre les dures réalités économiques. S&rsquo;il veut continuer à regarder Adibou ou Pokémon, faut raquer ;p. Alors que d&rsquo;autres solutions vont (parfois) jusqu&rsquo;à 10 ou 12 appareils, Surfshark vous permet de protéger absolument tout et tout le monde. L&rsquo;ordinateur fixe,&nbsp;les 2 laptops, les 4 téléphones portables, la console de salon, le routeur&nbsp;et les équipements de la maison (Smart TV &amp; Co) &#8230; tout sera pris en charge.</p>\n\n\n\n<p>Et surtout, en plus d&rsquo;être très abordable, Surfshark est&nbsp;un VPN parmi les plus fiables actuellement sur le marché.

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&rsquo;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&rsquo;est mignon, rigolo, et bien pensé !</p>\n\n\n\n<p>Ce qui frappe en premier lieu, c&rsquo;est l&rsquo;univers graphique, très différent de ce qu&rsquo;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&rsquo;étais sceptique mais une fois dans le jeu, franchement, à part quelques points particuliers, c&rsquo;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&rsquo;excellentes musiques, et on est embarqué direct dans l&rsquo;ambiance ! On retrouve le thème principal de la série, évidemment, mais pas que. 😉 Les arrangements sont super réussis, j&rsquo;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&rsquo;énigmes. Qu&rsquo;en est-il de ce côté là ? Eh bien, je suis désolé pour le manque de suspense mais c&rsquo;est encore une réussite. 🦜 L&rsquo;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&rsquo;est une bonne idée mais attention, ça enlève certaines énigmes et donc certaines parties de l&rsquo;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&rsquo;histoire est vraiment très bien écrite, c&rsquo;est super drôle et prenant. Le rythme énigmes / dialogues / découverte de nouveaux lieux m&rsquo;a semblé équilibré, avec toujours une certaine liberté dans l&rsquo;ordre d&rsquo;appréhender les choses. On est jamais totalement coincé devant un truc sans savoir quoi faire, on peut toujours aller voir ailleurs et avancer d&rsquo;une manière ou d&rsquo;une autre.</p>\n\n\n\n<p>Au pire, y a un système d&rsquo;aide intégré au jeu, qui donne quelques indices sans jamais dévoiler la solution. Vraiment mieux que d&rsquo;aller chercher la <em>soluce</em> sur le web, c&rsquo;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&rsquo;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&rsquo;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>&#8230; Pour moins de 25€ je ne peux que vous le conseiller !</p>\n",

Ce n&rsquo;est pas un plaisir pour eux, surtout qu&rsquo;en général, le premier contact qu&rsquo;on a avec quelqu&rsquo;un, qui plus est par Internet, se fait via l&rsquo;écrit.</p>\n\n\n\n<p>Et si le message est bourré de fautes, l&rsquo;autre en face a vite fait de ranger celui qui lui écrit dans un tiroir mental étiqueté « teubé » ou assimilé alors que ce n&rsquo;est pas forcément le cas.</p>\n\n\n\n<p>Sachez-le, quand vous faites des erreurs à l&rsquo;écrit, vous vous démarquez négativement, et cela même si vous avez de bonnes raisons « techniques » de massacrer l&rsquo;orthographe. C&rsquo;est triste mais c&rsquo;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&rsquo;est aussi très « douloureux ». Lire un texte plein de fautes, c&rsquo;est buter sur chaque mot. L&rsquo;expérience n&rsquo;est pas agréable. Pire, quand on est censé lire un article rédigé par un journaliste, un professionnel, on se dit qu&rsquo;on est vraiment tombé sur des amateurs. Pourtant, les coquilles existent, j&rsquo;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&rsquo;en fout et on espère qu&rsquo;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&rsquo;équipe.

Mais le mieux c&rsquo;est encore de programmer tout cela, avec des analyses régulières (par exemple 1 fois par semaine), ce qui permet de tout simplement l&rsquo;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&rsquo;autres antivirus (gratuits la plupart du temps) se contentent d&rsquo;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&rsquo;outil pour que celui-ci analyse son contenu.</p>\n\n\n\n<p>Concernant le moteur de l&rsquo;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&amp;aff_id=13768&amp;source=fixed-av1\" target=\"_blank\" rel=\"noopener\">Surfshark Cloud Protect</a> qui mutualise toutes les détections de virus à l&rsquo;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&rsquo;est un antivirus encore jeune, mais solide puisqu&rsquo;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&rsquo;avantage avec l&rsquo;antivirus Surfshark, c&rsquo;est que si vous utilisez déjà leur VPN, vous n&rsquo;aurez rien à installer de plus (il faut juste prendre l&rsquo;abonnement Surfshark One). Et si vous hésitiez à choisir un VPN ou un Antivirus, grâce à l&rsquo;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&amp;aff_id=13768&amp;source=fixed-av1\" target=\"_blank\">Je vous invite à en découvrir plus en cliquant ici.</a></p>\n",

Mais est-ce la seule chose que vous pouvez faire ? Bien sûr que non. Et aujourd&rsquo;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&rsquo;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&rsquo;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&nbsp;moula en la revendant une fois qu&rsquo;elle a fermé ses portes. Bref tout atterrit <strong><a href=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768&amp;source=inc\" target=\"_blank\" rel=\"noopener\">chez des data brokers qui collectent toutes ces infos</a></strong> et les revendent à prix d&rsquo;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&rsquo;entreprise lorsque vous créez une société, ou dans les fichiers PDF d&rsquo;un listing de diplômés d&rsquo;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&nbsp;les vaches à lait de cette industrie</strong>. De manière directe&nbsp;ou au moins via les personnalités que nous nous créons en ligne (qui finissent par nous ressembler au final). Et s&rsquo;il est difficile de supprimer à 100% toutes nos traces numériques (surtout que la plupart du temps nous ne sommes même pas conscients d&rsquo;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&rsquo;est pas nécessaire</h3>\n\n\n\n<p>Bon je sais, vous allez me dire que c&rsquo;est obvious. Je sais que ce n&rsquo;est pas votre cas, mes lecteurs adorés ont un QI supérieur à la moyenne. Mais qui ne connait pas une personne qui&nbsp;s&rsquo;ouvre un compte sur&nbsp;un e-commerce quelconque&nbsp;pour commander un objet pas cher et va ensuite laisser son compte existant pendant des années ? Peut-être qu&rsquo;en se demandant au départ si l&rsquo;objet en question est vraiment utile, le compte n&rsquo;aurait jamais eu besoin d&rsquo;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&rsquo;ouvrir un 4e compte Instagram pour publier uniquement les photos&nbsp;de la tortue de compagnie&nbsp;est vraiment utile ? À vous de voir. Et si c&rsquo;est le cas, passez au point suivant lorsqu&rsquo;il ne vous est plus d&rsquo;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&rsquo;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&rsquo;il n&rsquo;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&rsquo;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&#8217;email) sur des sites abandonnés comme MySpace, Flickr, StumbleUpon ou que sais-je&nbsp;? 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).&nbsp;Pire, imaginez qu&rsquo;il y a&nbsp;10 ans vous aviez un Skyblog&nbsp;avec une photo gênante et que l&rsquo;on parvienne à recouper l&rsquo;info avec votre adresse mail toujours active aujourd&rsquo;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&rsquo;est parfois bien caché dans les options, il faut parfois envoyer un mail personnalisé, etc., mais prenez le temps de le faire.&nbsp;Vous pouvez vous aider d&rsquo;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&rsquo;il y a moyen de limiter ça.</p>\n\n\n\n<h3>3) Renforcez la&nbsp;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&rsquo;effectuer les quelques clics nécessaires. Surtout que les réseaux sont sans doute LA source de récolte numéro 1 à l&rsquo;heure actuelle. Lorsque vous partagez votre localisation, balancez une photo d&rsquo;un endroit que vous visitez, parlez sans arrêt avec une même personne, etc. il n&rsquo;est pas très compliqué pour les algorithmes de vite se faire une&nbsp;image assez précise de vous, de vos préférences&nbsp;et de qui sont vos proches.</p>\n\n\n\n<p>Et c&rsquo;est d&rsquo;autant plus le cas lorsque vous connectez les services entre-eux (en vous connectant à des sites tiers avec vos identifiants Google ou&nbsp;Facebook par exemple), là ce sont tous les&nbsp;services interconnectés&nbsp;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&nbsp;rentables possibles ? Il leur faut accéder au max de vos infos, bingo.&nbsp;Donc les paramètres de protections par défaut sont (trop) souvent&nbsp;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&nbsp;votre profil visible publiquement, retirer la géolocalisation,&nbsp;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&nbsp; je vous ai fait un petit guide&nbsp;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.&nbsp;</p>\n\n\n\n<p>Ce n&rsquo;est pas non plus une mauvaise idée de supprimer vos anciens posts/tweets/photos, etc. s&rsquo;ils n&rsquo;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&nbsp;Edge, Apple Safari&nbsp;&amp; 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&rsquo;ils se rendront compte que vous l&rsquo;utilisez. Mais, quel que soit celui que vous choisissez, continuer à limiter le nombre d&rsquo;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&nbsp;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&nbsp;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&rsquo;ils puissent continuer à les revendre. Si certains sont très connus (Spokeo, WhitePages &#8230;) pour d&rsquo;autres, il est très compliqué de remonter jusqu&rsquo;à eux. Si vous recevez un email de scam, un coup de fil marketing, etc. comment savoir d&rsquo;où ces gens ont&nbsp;obtenu vos infos ? Et lorsque vous avez fait ce travail digne de l&rsquo;inspecteur Derrick il faut encore obtenir du data broker qu&rsquo;il supprime ce qui doit l&rsquo;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&rsquo;est là qu&rsquo;intervient un service <a rel=\"noreferrer noopener\" href=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768&amp;source=inc\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768&amp;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&nbsp;pour qu&rsquo;ils&nbsp;suppriment ces données&nbsp;et ensuite en faisant un suivit pour s&rsquo;assurer qu&rsquo;elles ne réapparaissent pas dans les prochaines années. Et si les brokers ne répondent pas aux demandes, Incogni va les relancer jusqu&rsquo;à ce que ce soit fait. Qu&rsquo;ils soient contactés par un service dont c&rsquo;est la spécialité ou par le mail dindon63@gmail.com de Mr Machin , ça risque de faire&nbsp;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&nbsp;figée (même adresse mail, même numéro de téléphone, mêmes services utilisés &#8230;), 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&rsquo;ai d&rsquo;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&rsquo;on prend seulement conscience de l&rsquo;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&amp;aff_id=13768&amp;source=inc\" data-type=\"URL\" data-id=\"https://get.incogni.io/aff_c?offer_id=959&amp;aff_id=13768&amp;source=inc\" target=\"_blank\">Découvrez Incogni !</a></h2>\n",

Déjà, y&rsquo;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&rsquo;on trouve un peu partout, intégrant le plus souvent B2, au côté d&rsquo;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&rsquo;est un peu relou de devoir tout refaire sur B2. Surtout que là, on sort un peu de l&rsquo;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&rsquo;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&rsquo;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&rsquo;idée c&rsquo;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&rsquo;est simple, il faut gruger un peu et faire croire à l&rsquo;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&#8230;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&rsquo;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&rsquo;autres cas d&rsquo;usage pour cet outil.</p>\n\n\n\n<p>Et sous macOS, c&rsquo;est le même concept sauf que ce n&rsquo;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&rsquo;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&rsquo;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&rsquo;édition de la config d&rsquo;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&rsquo;un nom (name) (Vous mettre ce que vous voulez)</li><li>D&rsquo;un ou plusieurs emplacements (locations)</li><li>D&rsquo;actions (actions) pour afficher des messages ou agir sur les fichiers</li><li>Et d&rsquo;un tas d&rsquo;autres paramètres comme le parcours des sous dossiers, le filtrage des fichiers par extension&#8230;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&rsquo;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&rsquo;outil dispose également d&rsquo;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&rsquo;outil est capable d&rsquo;extraire du contenu de PDFs ou de fichiers DOCX&#8230;etc our mieux les catégoriser. C&rsquo;est hyper puissant.</p>\n\n\n\n<p>Un mode « simulation » permet également de tester vos règles sans risque afin d&rsquo;éviter de massacrer vos fichiers en cas d&rsquo;erreur.</p>\n\n\n\n<p>Bref, un outil formidable qui en fait beaucoup. L&rsquo;essayer c&rsquo;est l&rsquo;adopter !</p>\n",

Les nouveaux pays sont le Ghana, l&rsquo;Arabie Saoudite et Puerto Rico.</p>\n\n\n\n<p>L&rsquo;interface pour Linux (souvent le parent pauvre des OS) a récemment été retravaillée pour&nbsp;plus de lisibilité&nbsp;et voit l&rsquo;ajout d&rsquo;un bouton Kill Switch plutôt pratique. <strong>Le mode camouflage</strong> est, lui aussi, toujours de la partie.

Un moteur de recherche (<em>Surfshark Search</em>)&nbsp;qui vous permet d&rsquo;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>)&nbsp;qui permet&nbsp;d&rsquo;être alerté si certaines de vos informations personnelles sont divulguées.

Si vous utilisez déjà Surfshark pour surfer, vous n&rsquo;aurez rien de plus à installer pour profiter de l&rsquo;antivirus. Celui-ci est intégré au logiciel et ça permet d&rsquo;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&amp;aff_id=13768&amp;source=fixed-av1\" target=\"_blank\">l&rsquo;antivirus Surfshark est vraiment très facile à utiliser</a>. Comme vous pouvez le voir sur les captures écran, l&rsquo;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&rsquo;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&rsquo;antivirus propose tout le nécessaire que nous sommes en droit d&rsquo;attendre d&rsquo;un antivirus. Tout d&rsquo;abord, il est possible de lancer des analyses manuelles de vos disques dès que vous en ressentez le besoin. Mais le mieux c&rsquo;est encore de programmer tout cela, avec des analyses régulières (par exemple 1 fois par semaine), ce qui permet de tout simplement l&rsquo;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&rsquo;autres antivirus (gratuits la plupart du temps) se contentent d&rsquo;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&rsquo;outil pour que celui-ci analyse son contenu.</p>\n\n\n\n<p>Concernant le moteur de l&rsquo;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&amp;aff_id=13768&amp;source=fixed-av1\" target=\"_blank\" rel=\"noopener\">Surfshark Cloud Protect</a> qui mutualise toutes les détections de virus à l&rsquo;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&rsquo;est un antivirus encore jeune, mais solide puisqu&rsquo;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&rsquo;avantage avec l&rsquo;antivirus Surfshark, c&rsquo;est que si vous utilisez déjà leur VPN, vous n&rsquo;aurez rien à installer de plus (il faut juste prendre l&rsquo;abonnement Surfshark One). Et si vous hésitiez à choisir un VPN ou un Antivirus, grâce à l&rsquo;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&amp;aff_id=13768&amp;source=fixed-av1\" target=\"_blank\">Je vous invite à en découvrir plus en cliquant ici.</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&rsquo;une même pièce puissent « discuter », il nous faut des API. API, ça veut dire Application Programming Interface et c&rsquo;est tout simplement un ensemble d&rsquo;instructions permettant aux applications de communiquer entre elles. Maintenant des types d&rsquo;API, il y en a des tonnes, mais je vous propose qu&rsquo;aujourd&rsquo;hui on s&rsquo;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&rsquo;est forcement quelque chose que vous devez apprendre et maitriser. De la même manière, quand on débute sa carrière de développeur ou qu&rsquo;on a déjà beaucoup d&rsquo;années au compteur mais qu&rsquo;on ne connaît pas sa valeur sur le marché de l&#8217;emploi, il est bon de connaître la grille des salaires en France. Ça tombe bien puisque&nbsp;<strong><a href=\"https://join.talent.io/tech-salary-report-fr?utm_source=korben&amp;utm_medium=partnership&amp;utm_campaign=Q4&amp;utm_content=article1\" target=\"_blank\" rel=\"noopener\">talent.io a mis en ligne une étude des salaires de la tech en 2022</a></strong>&nbsp;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&amp;utm_medium=partnership&amp;utm_campaign=Q4&amp;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&rsquo;est quoi une API RESTful ?</h2>\n\n\n\n<p>REST, ça veut dire « Representational State Transfer ». Lorsqu&rsquo;une API respecte les contraintes de REST, on parle alors d&rsquo;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&#8230;etc.) et que les requêtes et les réponses de l&rsquo;API soient dans un format texte tels que JSON, HTML, XML&#8230;etc.</p>\n\n\n\n<p>Les API RESTful sont alors mises à disposition des applications via ce qu&rsquo;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&rsquo;ai une API qui permette de lister des utilisateurs, mais également d&rsquo;en créer des nouveaux.</p>\n\n\n\n<p>L&rsquo;URI de mon API est la suivante : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>https:&#47;&#47;url.com/api/user</code></pre>\n\n\n\n<p>Le but du jeu, c&rsquo;est d&rsquo;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&rsquo;utilisateur qu&rsquo;on souhaite créer (nom, prénom&#8230;etc.) : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>POST: /user/</code></pre>\n\n\n\n<p>L&rsquo;idée là, c&rsquo;est de vous montrer qu&rsquo;on peut interagir avec l&rsquo;API à l&rsquo;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&rsquo;est aussi simple que cela. Et en retour le serveur peut alors répondre avec des codes de status HTTP classiques comme 200, 201, 2002&#8230;etc. pour dire que tout est OK, ou des codes de redirection 3xx, d&rsquo;erreur client 4xx ou d&rsquo;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&rsquo;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&rsquo;est pourquoi on l&rsquo;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&rsquo;on apprenne à en créer une de zéro. Vous allez voir, c&rsquo;est super simple.</p>\n\n\n\n<p>Pour cette démo, j&rsquo;ai choisi d&rsquo;utiliser Python comme d&rsquo;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&rsquo;API, nous allons utiliser un outil qui permet à la fois de balancer nos requêtes et de voir si les réponses correspondent bien. L&rsquo;un des plus connus s&rsquo;appelle Postman et c&rsquo;est gratuit en version de base pour tester. L&rsquo;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&rsquo;assez simple permettant de créer, supprimer, lire et mettre à jour des données. Admettons que j&rsquo;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&rsquo;y référencer mes produits :</p>\n\n\n\n<pre class=\"wp-block-code\"><code>products = &#91;\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&rsquo;un produit à partir de son ID. Comme vous pouvez le voir, on fait une boucle « for » qui va parcourir l&rsquo;ensemble des produits et si l&rsquo;ID correspond à ce qui spécifié dans la requête, on renvoie l&rsquo;objet « product » avec son code HTTP 200 et si ce n&rsquo;est pas le cas, on renvoie un message « Produit introuvable » accompagné d&rsquo;un code d&rsquo;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&#91;\"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&#91;\"id\"]):\n return \"Ce produit {} existe deja\".format(id), 400\n\n product = {\n \"id\": id,\n \"name\": args&#91;\"name\"],\n \"price\": args&#91;\"price\"],\n \"category\": args&#91;\"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&rsquo;est bien déroulée. Et si le produit existait déjà avec cet ID, on renvoie le code 400 avec un message d&rsquo;erreur.</p>\n\n\n\n<p>La fonction put suivante est assez similaire puisqu&rsquo;elle permet à la fois de créer un nouveau produit (si l&rsquo;id n&rsquo;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&#91;\"id\"]):\n product&#91;\"name\"] = args&#91;\"name\"]\n product&#91;\"price\"] = args&#91;\"price\"]\n product&#91;\"category\"] = args&#91;\"category\"]\n return product, 200\n\n product = {\n \"id\": id,\n \"name\": args&#91;\"name\"],\n \"price\": args&#91;\"price\"],\n \"category\": args&#91;\"category\"]\n }\n products.append(product)\n return product, 201</code></pre>\n\n\n\n<p>Enfin, vous l&rsquo;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 = &#91;product for product in products if product&#91;\"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&rsquo;à spécifier le format de l&rsquo;URI qui sera utilisé pour appeler l&rsquo;API et lancer l&rsquo;API (en mode debug pour démarrer). Le paramètre &lt;int:id&gt; permet d&rsquo;indiquer que dans le chemin du endpoint, on peut ajouter une variable acceptée par l&rsquo;API (ici l&rsquo;ID du produit).</p>\n\n\n\n<pre class=\"wp-block-code\"><code>api.add_resource(Product, \"/product/&lt;int:id&gt;\")\napp.run(debug=True)</code></pre>\n\n\n\n<h2>Tester l&rsquo;API avec Postman</h2>\n\n\n\n<p>Enfin, il ne reste plus qu&rsquo;à lancer le script python à l&rsquo;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\"

d&rsquo;un nouvel ID c&rsquo;est qu&rsquo;il soit généré directement par le code de l&rsquo;API, mais c&rsquo;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=\"\" class=\"wp-image-130934\" width=\"819\" height=\"547\"

ça&#8230;</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"1024\" height=\"662\"

/></figure></div>\n\n\n<h2>Et ensuite ?</h2>\n\n\n\n<p>Vous l&rsquo;aurez compris, ce n&rsquo;est vraiment pas compliqué à développer. Ici on est sur un exemple simple, mais ensuite, vous devrez pourquoi pas sortir vos données d&rsquo;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&rsquo;URI est xxxx/product/. J&rsquo;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&rsquo;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&#91;\"id\"]):\n return product, 200\n return \"Product not found\", 404</code></pre>\n\n\n\n<p>Ainsi, en passant l&rsquo;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&rsquo;oubliez pas également de documenter l&rsquo;ensemble de votre API afin de vous y retrouver et surtout d&rsquo;indiquer à d&rsquo;autres développeurs, comment l&rsquo;intégrer.</p>\n\n\n\n<p>Voilà, j&rsquo;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&nbsp;<strong><a href=\"https://join.talent.io/tech-salary-report-fr?utm_source=korben&amp;utm_medium=partnership&amp;utm_campaign=Q4&amp;utm_content=article1\" target=\"_blank\" rel=\"noopener\">créer un compte sur la plateforme talent.io</a></strong>&nbsp;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",

Seulement, voilà&#8230; Non seulement il faut être très précis dans ce qu&rsquo;on souhaite, mais également connaitre quelques mots clés et paramètres à passer à MidJourney ou d&rsquo;autres pour avoir un bon résultat.</p>\n\n\n\n<p>Heureusement, <a href=\"https://promptomania.com/\" target=\"_blank\" rel=\"noopener\"><strong>Promptomania</strong></a> est là pour vous aider. Ce site vous permet de construire des « prompts », c&rsquo;est-à-dire des phrases à destination d&rsquo;outils comme Midjourney ou encore Stable Diffusion.</p>\n\n\n\n<p>Le principe est simple. Vous lui passez des URLs d&rsquo;images dont vous aimez le style, vous agrémentez tout cela de mots clés que vous pouvez pondérer puis vous pouvez choisir <a href=\"https://github.com/willwulfken/MidJourney-Styles-and-Keywords-Reference\" target=\"_blank\" rel=\"noopener\">des tas de paramètres et de styles</a> proposés et supportés par votre générateur (au hasard Midjourney) afin d&rsquo;obtenir le résultat de vos rêves.</p>\n\n\n\n<p>Après moultes essais et inspiration prise dans la galerie de Midjourney et à l&rsquo;aide de DoctorMars (fidèle de Korben.info), j&rsquo;ai réussi à passer de ça :</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/vik1.webp\" alt=\"\" class=\"wp-image-130559\" width=\"493\" height=\"129\" srcset=\"https://korben.info/app/uploads/2022/09/vik1.webp 1000w, https://korben.info/app/uploads/2022/09/vik1-300x79.webp 300w, https://korben.info/app/uploads/2022/09/vik1-768x203.webp 768w\" sizes=\"(max-width: 493px) 100vw, 493px\" /></figure></div>\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-779997892\"><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>À ça :</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/vik2.webp\" alt=\"\" class=\"wp-image-130560\" width=\"512\" height=\"512\" srcset=\"https://korben.info/app/uploads/2022/09/vik2.webp 1000w, https://korben.info/app/uploads/2022/09/vik2-300x300.webp 300w, https://korben.info/app/uploads/2022/09/vik2-150x150.webp 150w, https://korben.info/app/uploads/2022/09/vik2-768x768.webp 768w\" sizes=\"(max-width: 512px) 100vw, 512px\" /></figure></div>\n\n\n<p>Ce que je peux vous dire, c&rsquo;est que ce n&rsquo;est pas aussi simple qu&rsquo;il y parait. Il faut prendre le temps de bien choisir ses mots et surtout faire de très nombreux essais pour avoir un bon résultat.</p>\n\n\n\n<p>J&rsquo;ai même généré une Chakchouka instagramable pour le délire : </p>\n\n\n\n<pre class=\"wp-block-code\"><code>photo of a Shakshuka in a copper pan with baked eggs in a tomato sauce, containing tomato, peppers, onions, eggs and parsley, colorful and appetizing, colors are red, yellow, white, green, orange, hyper realistic, instagram foodie style, highly intricate, ultra detailed, high dynamic range, HDR, dynamic light, octan render, unreal engine, 8k, --ar 9:16 --testp --upbeta</code></pre>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https://korben.info/app/uploads/2022/09/chak-700x1024.webp\" alt=\"\" class=\"wp-image-130565\" width=\"317\" height=\"464\" srcset=\"https://korben.info/app/uploads/2022/09/chak-700x1024.webp 700w, https://korben.info/app/uploads/2022/09/chak-205x300.webp 205w, https://korben.info/app/uploads/2022/09/chak-768x1123.webp 768w, https://korben.info/app/uploads/2022/09/chak.webp 1000w\" sizes=\"(max-width: 317px) 100vw, 317px\" /></figure></div>\n\n\n<p>C&rsquo;est hyper chronophage mais super plaisant.</p>\n",

On s&rsquo;affronte par équipe de 4 en balançant de l&rsquo;encre partout ; et c&rsquo;est l&rsquo;équipe qui aura colorié le plus de territoire de sa propre couleur qui gagne la partie. C&rsquo;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&rsquo;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&rsquo;est pas en reste, il s&rsquo;agit d&rsquo;un tutorial géant mais vraiment sympa, où l&rsquo;on alterne entre phases d&rsquo;exploration et épreuves, nous faisant découvrir un large éventail d&rsquo;armes et de techniques. Bref, au niveau du contenu, c&rsquo;est vraiment généreux, sans même parler des cosmétiques, rangs et armes à débloquer.</p>\n\n\n\n<div style=\"margin-left: auto; margin-right: auto; text-align: center; \" id=\"NKSYD1CP-1910884207\"><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>Techniquement, hormis la Cité-clabousse qui rame (allez savoir pourquoi), le jeu est ultra bien foutu : c&rsquo;est beau, lisible, super fluide ! La plate-forme réseau manque encore un peu de stabilité, mais elle est toute récente et s&rsquo;améliore continuellement, donc sur le moyen/long terme ça devrait le faire. Enfin j&rsquo;espère. 🤞</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/NSwitch_Splatoon3_03-1024x576.jpg\" alt=\"\" class=\"wp-image-130719\" srcset=\"https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_03-1024x576.jpg 1024w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_03-300x169.jpg 300w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_03-768x432.jpg 768w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_03-1536x864.jpg 1536w, https://korben.info/app/uploads/2022/10/NSwitch_Splatoon3_03.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" /></figure>\n\n\n\n<p>Les menus ne sont pas d&rsquo;une ergonomie sans faille, ils ont voulu faire un truc classe avec un hub, des boutiques, etc. C&rsquo;est joli mais au final on se perd un peu, on perd du temps, et pire, on passe à côté de certaines options (perso j&rsquo;ai mis un temps fou à comprendre comment jouer à Cartes &amp; Territoire, ou comment modifier la skin de mon inkling)… C&rsquo;est un peu dommage.</p>\n\n\n\n<p>Ceci étant dit, c&rsquo;est toujours mieux que dans Splatoon 2 ! 😁 Il y a de nettes améliorations, par exemple, on peut zapper l&rsquo;introduction de chaque nouvelle rotation de maps. Y a eu de vrais efforts pour rendre l&rsquo;expérience plus agréable. Quelques autres apports, en vrac :</p>\n\n\n\n<ul><li>Un meilleur lobby (avec entrainement pendant l&rsquo;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&rsquo;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&rsquo;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&rsquo;est à dire qu&rsquo;on fait la course, mais en se goinfrant le plus possible sur le chemin : car c&rsquo;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&rsquo;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&rsquo;essentiel : déplacement, saut, attaque spéciale (grâce aux bonus récupérés ici et là). Il y a juste la gestion de l&rsquo;inertie, propre à la petite boule qu&rsquo;on dirige, qui va demander quelques petites minutes d&rsquo;adaptation : le concept est aussi simple que la prise en main est immédiate, c&rsquo;est un party-game d&rsquo;une efficacité assez redoutable. Et tellement mignon&#8230; 🥰</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&rsquo;essentiel. Pas de quoi être déçu, car c&rsquo;est cohérent avec le prix affiché (15€). Pour les fous furieux, sachez qu&rsquo;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.

Donc du matos réellement testé sur lequel chacun vient donner son avis. À vous ensuite de faire le tri en fonction de ce qui vous intéresse.</p>\n\n\n\n<p>Est-ce le prix, la note du benchmark, la capacité, la vitesse ou la note globale ? À vous de choisir !</p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"1000\" height=\"444\" src=\"https://korben.info/app/uploads/2022/09/userbenchmark.webp\" alt=\"\" class=\"wp-image-130531\" srcset=\"https://korben.info/app/uploads/2022/09/userbenchmark.webp 1000w, https://korben.info/app/uploads/2022/09/userbenchmark-300x133.webp 300w, https://korben.info/app/uploads/2022/09/userbenchmark-768x341.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" /></figure></div>\n\n\n<p>Et évidemment, tout est filtrable par constructeur ou caractéristiques matérielles.
