  • BUT earth will move with gM/m1

    No. Multiplication is associative, you can switch the masses around as you please, nowhere in the formula does it say "the greater mass" or "the smaller mass" you could just as well re-arrange the formula and come up with "earth moves with gm1/M". Last but not least there's only one force acting on both objects... and gM/m1 is neither a speed nor a force. G * 100kg / 20kg is 5G. Measured in Nm²/kg² which is the same we started with because the two kg cancel each other out.

    They both fall towards their shared centre of gravity. It's this "the earth revolves around the sun" thing again, no it doesn't, they both revolve around their shared centre of gravity (which, yes, is within the sun but still makes it wobble). That centre is very far away from the ball and very close to the earth and both are moving at the same speed towards it (because acceleration doesn't depend on mass), blip to the next frame of the simulation now the centre of gravity moved towards the ball, next frame still closer to the ball, that is the reason both reach it at the same time, not because one is faster than the other.

    ...or so it would be, if the shared centre of gravity of ball and earth wouldn't lie within the earth so they don't actually both reach it, the earth is in the way, the rest of the acceleration is turned into static friction: Because they both are still falling even when in contact. But really that complication only exists because they have volumes which is why I factored it out from the rest of the reasoning.

  • ICANN isn't really a massive organisation, it's a technocratic non-profit with a buttload of advisory committees, including one for end users. The rules surrounding ccTLDs were tightened after Russia didn't sunset .su, so they tried to take politics out of it, make it a wholly rules-based thing, but now it figures that the rule everyone wants to have is "decide on a case-by-case basis".

    There's also been various initiatives regarding reform of internet governance over the decades but in the end noone can agree on what would be better so ICANN keeps on chugging on.

    You know what would bring a quick end to this? If Mauritius doesn't incorporate those islands into itself, letting them stay an autonomous territory. From British Indian Ocean Territory to Mauritian Indian Ocean Territory.

  • At least in Germany legal tender means "valid for payment of any obligation", also private ones. But if a shop says "we don't accept cash" then they're not entering a sales contract with you unless you agree to pay in another way, without contract no payment obligation to them so they're not required to accept anything, and if there is a contract, well, you agreed to the terms.

    I don't think the same would fly for e.g. rental or utility contracts, though. Any contract that isn't agreed upon and fulfilled while you're standing in front of the cashier.

  • In Germany any EU resident has a right to a basic account, in case you're homeless you should have an address because you're in a shelter, if you insist on sleeping rough (or the municipality is just too fucked up, happens in places) you can give the address of a social work organisation (those are all over also doing debtor counselling and a lot of other stuff).

    Only valid reason for a bank to refuse basic business is if you tried to defraud them. They don't have to give you a credit line, but they do have to accept your money, store it, and let you wire it (incl. POS payments etc).

    Identity fraud is not an issue because they'll want to see a proper ID which, if you're legally in the country, you have.

    It's less about paying, though, you can always pay with cash in Germany, it's about the welfare authorities not wanting to handle cash and cheques only if actually necessary.

  • Why would you hire a photographer instead of renting a camera, then?

    ...because you know shit about photography (I presume, for the sake of argument). Why would you hire an AI artist over doing it yourself, then?

  • the training data is not stored in the model in its original form,

    It is not stored in the model, period. Same as you do not store the shape of the letters you're reading right now, not even the words, but their overall meaning. Remembering the meaning of what I write here, you can then produce words and letters again and you might be close but even with this short paragraph you'll find it very hard to make an exact replica. That's because you did not store it in its original form, not even compressed, you re-encoded it using your own understanding of language, of the world, of everything.

  • “Oh, they didn’t. Nobody leaned the technique to paint this, there may not be any feeling behind it, or any point at all, other than ‘it looks good

    "May" being the important word, here.

    I suggest that if you cannot tell the difference between "someone who knows art did this piece" and "someone just hit generate" then you have no business critiquing art.

    And I’m pretty sure that most people could learn how to prompt successfully in a matter of days or weeks.

    ...that won't give you art skills. It's practically impossible to develop an artistic eye, much less mind, by hitting generate, the feedback isn't sufficient, you can't train like that. No model prompts the same, btw, frankly speaking prompting is about the worst way to condition a model when you're out to create something specific.

    The art is not in the fucking medium. Never was. Never will be. Come at me for this and I'll be referencing urinals on pedestals.

  • Cuba doesn't really pay much of a premium on their imports they're just cut off from the US. Did you know it's illegal for EU companies to bow to US sanctions on Cuba?

    Cuba's main issue is that they never really industrialised. Like, they're importing light switches from the EU and are paying in rum, honey, nickel, and tourism. Which actually wouldn't be an issue if they weren't dependent on energy imports.

  • It is illegal to use in the EU for anything even remotely sensitive. Like, if you subtitle a movie with it and it messes up noone cares, your problem, if you're doing anything that has any legal implications, from college applications over job interviews to court proceedings, they'll nail you to the cross. For AI to be used in such domains it has to be certified and AIs certified for even a subset of these things plainly don't exist.

    It's like with self-driving cars: What OpenAI is producing is pretty much on the level of Tesla's "full self driving". It's not even waymo who have proper autonomy tech certified to operate in a limited area in a benevolent (to venture capital) jurisdiction (some municipality or the other). Wake me when it gets actual approval from actual regulatory bodies actively trying to break it.

  • Nix is typed: there are strings, paths, lists, attrsets, etc;

    Those aren't types as far as programming language theory is concerned, they're (using Rust terminology) variants of enums.

    It's not really unityped ("dynamically typed") either, though, but it's a rather small wibble: Include paths aren't normal values, they must be statically evaluable. AFAIU that was some prescience regarding enabling future addition of separate compilation and maybe even proper typing.

    Otherwise the language is just the untyped lambda calculus with a couple of primitive data types thrown in, just like lisp, scheme, or also lua or js (if you squint a bit), what makes it different is that it's lazy and pure. Heck, it's a language where you have to write down the y combinator (which wouldn't work in typed lambda calculi) to do loops what else but the untyped lambda calculus is it supposed to be.

    That all said, nickel exists. The whole CLI situation as well the documentation is a mess because practically everyone is using flakes even though it's not an official feature (yet). And, of course, nixpkgs is nowhere close to having been ported to flakes, AFAIK we're not even close to starting. Personally I think it should be done at the same time as a move towards nickel as not to do it twice but that requires nickel to actually get integrated into nix (as in the package manager).

    tl;dr: NixOS is still very much in its "move fast and break the docs and all your habits" kind of phase. What it has going for itself, of course, is that "break things" doesn't happen while that's happening.

  • Just skimmed his position on Ukraine and it's the ole "only diplomacy will end the war" thing, ie. he ends up regurgitating Kremlin propaganda. Nah, Russia's economical and political collapse will end it because Russians won't have the collective will to get rid of Putin before that.

    He somewhat relented on the Red Khmer issue in retrospect but defended how he came to the initial conclusion, which is how he managed to repeat and repeat the same mistake again. The shit he said about Bosnia as far as I'm aware he never corrected even in parts and you shouldn't even ever *begin" to refer to starving concentration camp inmates behind barbed wire as "thin guys".

    I understand when USians value him for writing Manufacturing Consent (and I'll lump Canucks into that category because broader political sphere), but there's also a fucking reason he's persona non grata in Europe.
