<p>Laurence Paulson laments a bug that fooled Ramana Kumar using both Lean proof system and the Nanoda (plugin ? library ?) into thinking that he found a counterexample to the famous Collatz Conjecture [0]. It sounds like Kumar or someone extended the Lean software to postulate that a certain style of proof is true and Kumar's larger proof hallucinated a class of numbers that enter a cycle in the Collatz sequence.<p>[0] <a href="https://github.com/xrchz/CollatzLean" rel="nofollow">https://github.com/xrchz/CollatzLean</a> Paulson (mercifully?) did not link to Kumar's repository or paper [1]<p>[1] <a href="https://websim.com/@BookwormKevin/collatz-conjecture-simulation" rel="nofollow">https://websim.com/@BookwormKevin/collatz-conjecture-simulat...</a> this is a visualization of the Collatz sequence of numbers that is conjectured - but not proven - to <i>always</i> terminate at 1.<p>Paulson laments this as there are ways of building up the rules from axioms (program objects?), but it is really tedious. He recounts crafting a "system of combinators" (in 1986) that one could build on to express recursive functions.<p>[2] <a href="https://www.sciencedirect.com/science/article/pii/S0747717186800025?via%3Dihub" rel="nofollow">https://www.sciencedirect.com/science/article/pii/S074771718...</a> DOI 10.1016/S0747-7171(86)80002-5</p>

<p>This is a pretty short post observing that some art has achieved celebrity. Consider the Mona Lisa, you probably can imagine it just from the title. When I went to the Louvre, there was a mob around the (quite small) painting of people who - like me - came to finally see what we'd already seen dozens of times before. This post ends on the idea that celebrity is not always a measure of quality, given that many great works existed (and exist) without the marketing to vault them into larger social awareness.</p>

<p>Wikipedia is written by various people, but likely someone with interest in a given topic. One or more realtors probably wrote or edited this post.<p>Actually, the history of edits shows that this is contested territory where people regularly remove what they term as spam links. So, while a disinterested editor might remove a link to a listicle about how to stage your home, they might leave in the breathless tone as harmless. The drive by editors probably feel that they have no more time to rewrite it than we do, given that they watch over many articles, not just this one.</p>

<p>In 2022 [0], Jan David Nose (jdno) released a game / programming challenge called _Auto Traffic Control_ [1]. Rather than controlling airplanes with UI interactions, the simulation is a GRPC server that expects the player to construct a game client that issues flight paths.<p>I tried to make a game client for jdno's ATC [2]. My client was deficient, as I tried to treat the movement as a fixed interval, by only submitting flight plans that moved in cartesian directions. Only by cheating, modifying the simulator, could my greedy algorithm land any planes [3]. I suspect I was supposed to continuously model and poll the future positions of airplanes when developing a flight plan.<p>I suspect that I won't have much competition on the leaderboard, despite the asterisk, as jdno eventually archived the project [4]. Originally, the project was self-publication while looking for work. The Rust Foundation hired him a little while afterward.<p>[0] <a href="https://jdno.dev/auto-traffic-control/" rel="nofollow">https://jdno.dev/auto-traffic-control/</a><p>[1] <a href="https://auto-traffic-control.com/" rel="nofollow">https://auto-traffic-control.com/</a><p>[2] <a href="https://github.com/Nzen/hircine-anise-okkoz" rel="nofollow">https://github.com/Nzen/hircine-anise-okkoz</a><p>[3] <a href="https://www.youtube.com/watch?v=czsSjy1Uqyk" rel="nofollow">https://www.youtube.com/watch?v=czsSjy1Uqyk</a> 1.5 minutes<p>[4] <a href="https://github.com/jdno/auto-traffic-control/commit/b5972dfbfedf8419727adc116bf77951c8cc5202" rel="nofollow">https://github.com/jdno/auto-traffic-control/commit/b5972dfb...</a></p>

<p>I think that this is a plugin library for teams that want to offer a platform for the public (or an LLM-AI) to submit code to. If your team writes some code, you don't generally sandbox it from yourself, you just amend your program: you don't need a sandbox. But, if you want to run code that you don't trust, you should run it in a way that prevents it from causing problems if it is actually dangerous (like a virus or accidentally overwrites your files with blank files). That's what a sandbox like kyushu promises to do.<p>So, with a sandbox library like this, you could - say - write a website that hosts games (like itch.io or newgrounds) that hosts games on the world wide web. The sandbox part can give you confidence that, if a villain's programmer henchmen uploads a virus instead of a game, it can't infect your platform or other games on the website. Or, if a LLM-AI written game is accidentally tries to take up all the memory of the computer, it can't ask the operating system for more than is in the sandbox.</p>

Notice that it has no usage for a 'week' after April 15 (a Wednesday), but picks up a bunch later. As marketing copy it needn't have any basis in reality [2].

Basically, it checked in numbered files to their version control (CVS, at the time) that could produce reports with grep. This system's simplicity lead to its longevity, as people could learn it easily and trust that its bugs had been ironed out long ago. This is in contrast to some OS software that tries to be everything to everyone and changes all the time [1].<p>[0] <a href="https://en.wikipedia.org/wiki/Joe_Armstrong_(programmer)" rel="nofollow">https://en.wikipedia.org/wiki/Joe_Armstrong_(programmer)</a> Joe Armstrong, of Erlang fame, so his blog posts have been discussed in the past.<p>[1] <a href="https://ntdotdev.wordpress.com/2023/01/01/state-of-the-windows-how-many-layers-of-ui-inconsistencies-are-in-windows-11/comment-page-1/" rel="nofollow">https://ntdotdev.wordpress.com/2023/01/01/state-of-the-windo...</a><p>I find this a helpful example.

<p>tl;dr Eels have a long lifecycle with several stages. They do not develop sexual organs until late in their life, when they migrate back to the Saragossa Sea. This meant earlier autopsies of eels revealed no sexual organs, even though scientists could provoke them with hormone therapy. So, a team lead by Jose Azevedo tagged female eels in the Azores in 2018, and tracked them via satellite [0].<p>[0] <a href="https://www.nature.com/articles/s41598-022-19248-8" rel="nofollow">https://www.nature.com/articles/s41598-022-19248-8</a><p>I sometimes think about the selection pressures that lead to complex life cycles, like fig wasps.

I just notice it for, say, influenza because their cycle time is so short.</p>

<p>This sounds a lot like Jason Rohrer's project with an LLM, Sammy Jankis [0]. There, the posts are generally about the continual deaths when the LLM's context window fills up. The posts do not disclose an overt goal, as they do here, so the LLM has supposedly created a bunch of games and simulations.<p>[0] <a href="https://sammyjankis.com/" rel="nofollow">https://sammyjankis.com/</a><p>In this case, I think that 100$ as a starting budget (while probably appropriate for the initiating person) is not enough for a substantive business. I guess the server that runs the LLM is a subsidized asset, so this situation doesn't require renting one. I guess, as a hypothetical LLM, I could try to sell customized fan fiction to fetish communities. Most of the mainstream LLM hosts reputedly have guardrails to discourage such output. On the other hand, selling in those communities largely requires trust [1], but that might take time that this scenario doesn't permit.<p>[1] <a href="https://www.youtube.com/watch?v=emdki5B_O7Q" rel="nofollow">https://www.youtube.com/watch?v=emdki5B_O7Q</a> .
