<p>"Mathematics" is a mass noun that happens to look plural (ends in -s) but behaves singular: "Mathematics is hard" not "Mathematics are hard".<p><a href="https://en.wikipedia.org/wiki/Mass_noun" rel="nofollow">https://en.wikipedia.org/wiki/Mass_noun</a><p>>In linguistics, a mass noun, uncountable noun, non-count noun, uncount noun, or just uncountable, is a noun with the syntactic property that any part and quantity of it is treated as an undifferentiated unit, rather than as something with discrete elements. Uncountable nouns are distinguished from count nouns.<p>So "math" is the proper shortening of the mass noun "mathematics". What other mass nouns do you shorten by abbreviate by keeping the "s" ending?<p>We do not say "phys" for physics or "econs" for economics, so keeping the "s" in "maths" breaks the rule.</p>

<p>Number theory is all about cyclical patterns, and its theorems fetishize finding cycles of discrete values with suspiciously regular behavior. Last I heard, number theory, group theory, and Fourier analysis are all math.<p>And yes, I will die on this singular hill: it's all one math, not a bunch of "maths". Math is one interconnected cathedral with music flowing through it, not a drawer full of unrelated trinkets. The British habit of calling it "maths" is oddly reductionist -- it makes it sound like you've got separate jars labeled "algebra", "geometry", and "spicy numbers".</p>

<p>High dimensional vectors are thought (insofar as you can define what that even means). Tokens are one dimensional input that navigates the thought, and output that renders the thought. The "thinking" takes place in the high dimension space, not the one dimensional stream of tokens.</p>

<p>Speaking of first hand learning and applying those lessons: That's all very well and fine that you're using your free speech to speculate about the motives of ESR and his relationship to RMS, without having actually looked at any of the evidence yourself, but do you know either of them personally, and if so, for how long have you known them, and how often have you interacted?<p>Have you ever had to sit through ESR yapping at you relentlessly about TMNN in the 1980's? I have, and so have many of my friends from that era. It was all he would talk about at the time. He was notorious for his obsession with proselytizing about TMNN and trying to personally attack and tear down RMS's life's work. (Not to mention ESR's rank bouquet and Pepé Le Pew approach to women.)<p>Pepe Le Pew - We shall flee to Capri!<p><a href="https://www.youtube.com/watch?v=HMnbNTv_D3A" rel="nofollow">https://www.youtube.com/watch?v=HMnbNTv_D3A</a><p>ESR's Creepy Sex Tips For Geeks: How To Be Sexy:<p><a href="http://www.catb.org/~esr/writings/sextips/sexy.html" rel="nofollow">http://www.catb.org/~esr/writings/sextips/sexy.html</a><p>And nobody wanted to work with ESR because he was an insufferable narcissist who didn't want to share his code with anyone, who wanted all the glory and bragging rights himself.<p>All he did was brag and brag like Trump bloviating about how smart he is, dissing all the competing software that was actually free and other people worked on and shared, without ever sharing his own code, or letting "many eyes" review it, over two full years, until he gave up on his TMNN project and never touched or spoke of it again.<p>There is literally a 365 line 3,135 word 19,560 character file in the TMNN source code called "doc/BRAGSHEET":<p><a href="https://github.com/SimHacker/esr-tmnn7-8/blob/main/doc/BRAGSHEET" rel="nofollow">https://github.com/SimHacker/esr-tmnn7-8/blob/main/doc/BRAGS...</a><p>ESR's TMNN code wasn't a cathedral, a bazaar, or a mystery house -- it was a shanty town riddled with bugs and security holes far beyond the reach of "many eyes". I analyzed it with Claude: ~774 unsafe string call sites, 42 mktemp races, 61 shell-shaped holes, gets() normalized in a shared header. Review the code yourself if you don't believe me.<p><a href="https://github.com/SimHacker/esr-tmnn7-8/tree/main/src" rel="nofollow">https://github.com/SimHacker/esr-tmnn7-8/tree/main/src</a><p>Imagine him cornering you at a science fiction convention and having to sit through him reciting that BRAGSHEET file to you again and again. It was his entire personality and discussion topic for two years (besides how much he hated RMS).<p>ESR's obsession is all about RMS personally, not just the EFF in general. His own TMNN license and my own personal first hand experience proves it. Have you ever discussed it with RMS himself, or even anyone else involved in the Free Software Foundation, or seen both of them interact in person? I have. I still communicate with RMS occasionally -- the last time he emailed me was a couple weeks ago.<p>I'm speaking from first hand knowledge and direct personal experience over decades. I'm not speculating and hallucinating and trying to carry ESR's water like you are, without knowing either of them personally.</p>

<p>You are arguing theology about who the cathedral metaphor was aimed at. The primary sources from ESR's own flagship pre-CatB project are public and open to examination.<p>Teenage Mutant Ninja Netnews (TMNN) was ESR's failed magnum opus, a solo netnews rewrite: long private work, one rough beta, then done. That is the isolated cathedral process CatB later criticised when it was other people's work. The tree from the historic tmnn7-8.tar.Z is here:<p><a href="https://github.com/SimHacker/esr-tmnn7-8/tree/main" rel="nofollow">https://github.com/SimHacker/esr-tmnn7-8/tree/main</a><p>Read the LICENSE as evidence, not as law homework: anti-censorship language, FSF distancing, GPL-style terms, and a consulting pitch labeled as an unabashed commercial plug inside the license text:<p><a href="https://github.com/SimHacker/esr-tmnn7-8/blob/main/LICENSE" rel="nofollow">https://github.com/SimHacker/esr-tmnn7-8/blob/main/LICENSE</a><p>Then read fascist.c: real filename, FASCIST and COMMUNIST compile switches, suppress/deny and ADM/authorized rules for who may post or read. That is operator gatekeeping in code, not a metaphor.<p><a href="https://github.com/SimHacker/esr-tmnn7-8/blob/main/src/D.news/fascist.c" rel="nofollow">https://github.com/SimHacker/esr-tmnn7-8/blob/main/src/D.new...</a><p>ESR talks in that LICENSE like the speech police are the enemy. In the same distribution, fascist.c is the speech police: it encodes who may post, who may read, site suppressions, and deny rules off an authorized file. That is not a subtle contradiction. It is the same person packaging a freedom sermon with operator-controlled posting and reading. Calling that anything other than hypocrisy is charity he did not earn.</p>

<p>Peter Norvig should write an essay about teaching yourself pixel art in 10 years, to go with his article about programming:<p><a href="https://norvig.com/21-days.html" rel="nofollow">https://norvig.com/21-days.html</a><p>Teach Yourself Programming in Ten Years<p>Peter Norvig<p>Why is everyone in such a rush?<p>Walk into any bookstore, and you'll see how to Teach Yourself Java in 24 Hours alongside endless variations offering to teach C, SQL, Ruby, Algorithms, and so on in a few days or hours. The Amazon advanced search for [title: teach, yourself, hours, since: 2000 and found 512 such books. Of the top ten, nine are programming books (the other is about bookkeeping). Similar results come from replacing "teach yourself" with "learn" or "hours" with "days."<p>The conclusion is that either people are in a big rush to learn about programming, or that programming is somehow fabulously easier to learn than anything else. Felleisen et al. give a nod to this trend in their book How to Design Programs, when they say "Bad programming is easy. Idiots can learn it in 21 days, even if they are dummies." The Abtruse Goose comic also had their take.<p>[...]<p>Teach Yourself Programming in Ten Years<p>Researchers (Bloom (1985), Bryan & Harter (1899), Hayes (1989), Simmon & Chase (1973)) have shown it takes about ten years to develop expertise in any of a wide variety of areas, including chess playing, music composition, telegraph operation, painting, piano playing, swimming, tennis, and research in neuropsychology and topology. The key is deliberative practice: not just doing it again and again, but challenging yourself with a task that is just beyond your current ability, trying it, analyzing your performance while and after doing it, and correcting any mistakes. Then repeat. And repeat again. There appear to be no real shortcuts: even Mozart, who was a musical prodigy at age 4, took 13 more years before he began to produce world-class music. In another genre, the Beatles seemed to burst onto the scene with a string of #1 hits and an appearance on the Ed Sullivan show in 1964. But they had been playing small clubs in Liverpool and Hamburg since 1957, and while they had mass appeal early on, their first great critical success, Sgt. Peppers, was released in 1967.<p>[...]</p>

<p><i>WHOOSH</i>! You're completely missing the point that it's all Elon's fault, not his company's. GP was incorrect to blame Tesla for Musk's own failures. Blaming the destruction and undermining and toxicity on "them" is obfuscating the true cause, and smearing hard working innocent people, who didn't just shoot off their big fat racist mouths like Elon did.<p>Nobody else at Tesla made Nazi salutes, and publicly bullied, abused, and humiliated their own daughter, and perpetrated DOGE's destruction and corruption. Tesla ("they") had nothing to do with any of that, but suffered from Elon doing it.</p>
