bmacho··on The AI Race Just Got Awkward
They are solving unsolved math problems right now, so probably soon or very soon their output will be more valuable than all human recorded knowledge.
bmacho··on Tcl/Tk 9.1
It's very off-topic here.

I personally wouldn't put anything but Ubuntu on a computer that someone else has to use and I have to support. No Arch, Fedora, Suse.

The main reason is that I know it, how to configure it, and when it tends to do silly things. Secondary reason is that Ubuntu is a beginner friendly distro.

Unless you are familiar with Arch/Omarchy and/or have ideological reasons, I don't see the point of putting it on someone else's computer. If articles and videos are hyping it, they are probably wrong or don't apply to your case.

bmacho··on I switched to Brave
Google controls Chrome/Chromium on one side and Google/Youtube/Maps/Meet on the other side.

It can kill or force technologies.

bmacho··on You are a 1000x maker, and you can't think of how to make your stack 10x better?
Right now the twitter link is readable logged out, no javascript, while all these mirrors require javascript to show me 600 characters. (Both can change.)
bmacho··on Plunging test scores are a slow-moving catastrophe
I think it can shift rapidly when an addiction or compulsory behaviour becomes a problem.

For example, made-up numbers, but: 1-2 hours of doom-scrolling daily is okay, as it still leaves time for 1-2 hours of schoolwork at home. 3-4 hours of such doom-scrolling, doom-scrolling between classes or during classes will have a measurable negative effect on your academic knowledge and abilities. (I don't have much information on how US schoolkids live today.)

bmacho··on We're gonna need a lot more mathematicians

bmacho··on CAPTCHAs don't prove you're human – they prove you're American
I think you are supposed to click on all tiles that contain any part of said object (and pole is part of the stoplight object).

They certainly could've been more clear about what they want.

bmacho··on Gravity seems holographic. What does that mean for reality?
> Mathematician, not physicist, but it seems reasonable to me that you could encode a sufficiently constrained 3D space on a 2D boundary. And if you have such an encoding, it also doesn't seem insane that some things might be more easily modeled on the 2D boundary than the 3D space.

Yes, you are missing the point entirely. Merely saying "you could encode a sufficiently constrained 3D space on a 2D boundary" as you correctly noticed, would be meaningless.

The observation is that the 3D space has properties that are weird in 3D but natural in its 2D representation.

> does it matter which is "real"?

No.

Also if you have different representations of something and your job/goal is to think and gain instinct then you should keep in mind all the representations, they very likely will be useful. (An observed property of mathematics is that if a mathematician pours 40 hours per week of work in an area for years in a topic other mathematicians haven't exhausted yet, she will find something there.)

bmacho··on Dutch governments builds alternative for Microsoft based on NixOS
Well, yes really. If it is 2 days, and you've bought it online then you can just bring it back.

ishouldnotbutk8's message was mostly a joke since your argument would work with 15 days instead of 2. And yes, customers should be protected* against altering the deal.

Especially that it is so so common now, with the wide-spread of IT. Companies just push out malicious updates and changes in terms and conditions.

bmacho··on The Mafia may be keeping fentanyl out of Italy
> Who is being informed here?

I am being informed about the public opinion. Which I value more than articles. (Don't come me at with AI, I'm well aware that it makes all human communication bad and pointless in theory and more and more in practice, thx.)

bmacho··on Did OpenAI solve the wrong Navier-Stokes problem?
Article says that there are 2 formulations of the NS problem and both are interesting: one is about fluid behaviour with no external forces, other is about fluid behaviour with external forces.

For a counter-example the latter is easier since you can have a tricky external forcefield.

bmacho··on I vibed a proof of Conway's conjecture
> On the second day, there are two gaps: “between nothing and zero” and “between zero and nothing”. Two numbers spawn in those two gaps. Call them –1 and 1.

That's a mistake. They should've written "empty set of surreal numbers" and not "nothing".

It is a constructive theory, like sets/ordinals. For ordinals you can use ∅, { }, ∪ and you construct

  ∅, {∅}, {{∅},∅}, ... (von Neumann ordinals). 
For surreal numbers you use the form { A | B } where A and B are sets of surreal numbers. Some restrictions apply so not all of these forms will be surreal numbers.

You build up surreal numbers as

  {∅|∅}, {∅|{∅|∅}}, {{∅|∅}|∅}
and so on.

---

Edit: A happy accident: I denoted the "empty set of surreal numbers" with the symbol ∅. It works, and it gives you the surreal numbers. But if you think of ∅ as the empty set in set theory, then the same construction (using an ordered-pair construction) gives you the surreal numbers as sets!

bmacho··on Nvidia announces native GPU programming in Rust
IMO cr*p and crap are both valid but separate swear words. People have a wide option to choose from when they want to swear, and people like variety (much much more than LLMs do). People also tend to influence each other with their usages: cr*p is popular because it is popular.

Otherwise cr*p is just as good as crap, shit, horseshit, poopoo or such.

edit: * replaced with \* as HN interprets asterisks as formatting for emphasis. Thx latexr for informing me

> They've lost my trust since then, and I'll only run it sandboxed: https://gist.github.com/cielavenir/02f322e322a2a3555dbf2b38f...

On Linux/X11 even when you run a program sandboxed or as a different user if you use a master Xserver the sandboxed program still can listen and modify all your input/output including keyboard/mouse events and window content of every application.

bmacho··on Navier-Stokes Announcement
It's a common (most common?) word in mathematics in this meaning.

You interrogate a proof.

It's obviously true that when people try to recall memories they either

  1. recall them correctly
  2. say they can't recall them
  3. recall them incorrectly
Are you asking me a study on when people say they remember something (cases 1 and 3) they are usually right or wrong?

> The left hemisphere actively confabulates, inventing plausible explanations for actions it didn’t initiate, suggesting that much of human self-narrative may be post-hoc storytelling.

Sounds like the left hemisphere usually uses something from the right hemisphere to answer those questions and it can't do that if it's been cut off?

We know that our brains are capable of hallucinating due to substances (drugs), being asleep, brain damage (including split brain), hypnosis, etc. Just as RAM damage make your computer do weird shit. That doesn't mean it operates that way normally.

You can't just remove a huge part of a system and then assume that the whole system behaves the same.

Ask it to build you a simple and deterministic citation checking extension to your IDE that puts source in meta to citations. E.g. color citations green/red depending if they are valid.
bmacho··on Claude, change the “Add to Cart” button to blue
No. People have an inner monologue, partial results and ideas and they remember that.

If they've worked some minutes/hours/weeks on something and you ask them why did they do that, they will either answer honestly and truthfully, lie, or say "I missed that/didn't seem important so I just chose something at random".

None of these cases are similar to how AI works.

Sienkewicz analyzed additional heroes using Raglan's pattern, including Mithridates VI of Pontus (22 points), Krishna (21 points), Jesus (18 points), Mohammad (17 points), Beowulf (15 points), Buddha (15 points), Czar Nicholas II (14 points), Samson (13 points), Sunjata, the Lion-King of Ancient Mali (11 points), Achilles (10 points), and Harry Potter (8 points).

> So much for all the EdTech startups that want you to use their AI teachers.

Kid pasting the question into ChatGPT and pasting its answer back is not the same as an AI teacher persona.

In my mind an AI teacher can be like a traditional education package (syllabus, material, questions, keeping track of progression) but way more flexible. I don't see no reason why AI teachers shouldn't give Bloom's 2 sigma effect to kids (and adults) very soon.

bmacho··on It took a year to ship WebAssembly in Anubis
From someone who doesn't want to associate with it, I think 'anime girl' is fair. Even if people who consume it might (and do) categorize it otherwise.
bmacho··on bzip3
Different people have different licence preferences. "Why this and not that" questions usually don't spark joy. (Might seem fine for the individual who asks it, but not really in a community.)
bmacho··on Smartphone makers don't bother to comply with EU repairability requirements
Make the sticker text + QR link to a website so anyone with a smartphone could verify them if they wanted.

This could work for products too: have webshops add links to verdicts of inspections and also put them on the boxes (in link and QR code form).
