  • How much swap?

    Jump

  • I think it's better to think about what swap is, and the right answer might well be zero. If you try to allocate memory and there isn't any available, then existing stuff in memory is transferred to the swap file/partition. This is incredibly slow. If there isn't enough memory or swap available, then at least one process (one hopes the one that made the unfulfillable request for memory) is killed.

    If you ever do start swapping memory to disk, your computer will grind to a halt.

    Maybe someone will disagree with me, and if someone does I'm curious why, but unless you're in some sort of very high memory utilization situation, processes being killed is probably easier to deal with than the huge delays caused by swapping.

    Edit: Didn't notice what community this was. Since it's a webserver, the answer requires some understanding of utilization. You might want to look into swap files rather than swap partitions, since I'm pretty sure they're easier to resize as conditions change.

  • Fosstodon's position on Meta's Threads

    Jump

  • I'm not sure this is a level headed take... They say, when someone tells you who they are, believe them. Meta has already made it very clear who they are; I'm not sure skepticism is really in order.

  • I'm not a Mastodon expert, but I'm pretty sure you can still get their memes if they reply to you (or @ you), or if they post to a tag you're following.

  • Fosstodon's position on Meta's Threads

    Jump

  • Well... They are of course right about the fact that these sorts of decentralized systems don't have a lot of privacy. It's necessary to make most everything available to most everyone to be able to keep the system synchronized.

    So stuff like Meta being able to profile you based on statistical demographic analysis basically can't be stopped.

    It seems to me, the dangers are more like...

    Meta will do the usual rage baiting on its own servers, which means that their upvotes will reflect that, and those posts will be pushed to federated instances. This will almost certainly pollute the system with tons of stupid bullshit, and will basically necessitate defederating.

    It'll bring in a ton of, pardon the word, normies. Facebook became unsavory when your racist uncle started posting terrible memes, and his memes will be pushed to your Mastodon feed. This will basically necessitate defederating.

    Your posts will be pushed to Meta servers, which means your racist uncle will start commenting on them. This will basically necessitate defederating.

    Then yes there's EEE danger. Hopefully the Mastodon developers will resist that. On the plus side, if Meta does try to invade Lemmy, I'm pretty confident the Lemmy developers won't give them the time of day.

  • What's your "old person" trait?

    Jump

  • It goes along with how they've stopped calling it a user interface and started calling it a user experience. Interface implies the computer is a tool that you use to do things, while experience implies that the things you can do are ready made according to, basically, usage scripts that were mapped out by designers and programmers.

    No sane person would talk about a user's experience with a socket wrench, and that's how you know socket wrenches are still useful.

  • I crave mental lint. Hivemind, please share your interesting facts

    Jump

  • Here's a random interesting car fact. The accelerator pedal only controls how much air makes it to the engine; it opens and closes a flap in the air intake called the throttle body. The car has a sensor that records how much air is coming in, the mass airflow sensor, which is just a wire in the airstream. Electrical resistance in metals is proportional to temperature, and the air rushing by cools the wire. The car's computer is then programmed to inject fuel according to the estimated amount of air coming in, which is double checked with oxygen sensors in the exhaust (which detect uncombusted air, i.e., too little fuel).

  • Biden Is Wrong. The Supreme Court Is Already “Politicized.”

    Jump

  • Ultimately we need a "Roberts has made his decision, now let him enforce it" moment. The supreme court wished all its power into existence, so it only lasts as long as most people are willing to go along with the lie.

    On the other hand, the president openly defying the supreme court would be a risky move with voters, so as usual, the buck stops with Us. And here we are.

  • OpenAI being Sued for "Stealing" Peoples Content Online

    Jump

  • This is proof of one thing: that our brains are nothing like digital computers as laid out by Turing and Church.

    What I mean about compilers is, compiler optimizations are only valid if a particular bit of code rewriting does exactly the same thing under all conditions as what the human wrote. This is chiefly only possible if the code in question doesn't include any branches (if, loops, function calls). A section of code with no branches is called a basic block. Rust is special because it harshly constrains the kinds of programs you can write: another consequence of the halting problem is that, in general, you can't track pointer aliasing outside a basic block, but the Rust program constraints do make this possible. It just foists the intellectual load onto the programmer. This is also why Rust is far and away my favorite language; I respect the boldness of this play, and the benefits far outweigh the drawbacks.

    To me, general AI means a computer program having at least the same capabilities as a human. You can go further down this rabbit hole and read about the question that spawned the halting problem, called the entscheidungsproblem (decision problem) to see that AI is actually more impossible than I let on.

  • Evidence, not really, but that's kind of meaningless here since we're talking theory of computation. It's a direct consequence of the undecidability of the halting problem. Mathematical analysis of loops cannot be done because loops, in general, don't take on any particular value; if they did, then the halting problem would be decidable. Given that writing a computer program requires an exact specification, which cannot be provided for the general analysis of computer programs, general AI trips and falls at the very first hurdle: being able to write other computer programs. Which should be a simple task, compared to the other things people expect of it.

    Yes there's more complexity here, what about compiler optimization or Rust's borrow checker? which I don't care to get into at the moment; suffice it to say, those only operate on certain special conditions. To posit general AI, you need to think bigger than basic block instruction reordering.

    This stuff should all be obvious, but here we are.

  • The thing that amazes me the most about AI Discourse is, we all learned in Theory of Computation that general AI is impossible. My best guess is that people with a CS degree who believe in AI slept through all their classes.

  • The issue will have to be litigated, but... A lawyer once told me that there aren't really "lawsuits" so much as "factsuits." The actual judgment in a trial comes more down to the facts at issue than the laws at issue. This sure looks an awful lot like IBM strong arming people into not exercising their rights under the license agreement that IBM chose to distribute under. If it is ever litigated, it isn't hard to imagine the judgment going against IBM.
