    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.




  • I’ve used it a bit to try and work on my Spanish. That is, using it as a sophisticated chatbot. Unfortunately it’s still quite frustrating for that: I figured I’d ask it to play un juego de rol (a roleplaying game), and it kinda sucks at it. I’m gonna give it a go with an open source alternative, hopefully they’re less aggressively calibrated toward being tedious and awful. It’s just, getting an open source language model running takes a decent amount of time and effort, so I’m sorta midway through that.



  • It’s older, but The Longest Journey is good. Unfortunately, the final game in the series kinda sucks.

    While it’s an ensemble, most people would agree that the main character of Final Fantasy VI is a woman—they just might disagree about which woman is the lead.

    I also liked the first Xenosaga game, but again, it’s a series that goes pretty badly downhill.




  • I guess the important thing to understand about spurious output (what gets called “hallucinations”) is that it’s neither a bug nor a feature, it’s just the nature of the program. Deep learning language models are just probabilities of co-occurrence of words; there’s no meaning in that. Deep learning can’t be said to generate “true” or “false” information, or rather, it can’t be meaningfully said to generate information at all.

    So then people say that deep learning is helping out in this or that industry. I can tell you that it’s pretty useless in my industry, though people are trying. Knowing a lot about the algorithms behind deep learning, and also knowing how fucking gullible people are, I assume that—if someone tells me deep learning has ended up being useful in some field, they’re either buying the hype or witnessing an odd series of coincidences.








  • I don’t really like driving, but it is necessary. My (main) car is a 1993 Mazda Miata, which is currently being repainted bright yellow, and I’m gonna put a new top on it next. It isn’t fast, but it handles extremely well and it’s fun to drive. Or at least, it makes driving as fun as it can be.

    I think anyone who’s driven a Miata understands.




  • We’d need to see their financials, which is tricky since they aren’t public yet. There’s also the issue, Steve lies about everything, so should we believe he’s telling the truth?

    But my guesses would go like this:

    Since they’ve been spending other people’s money, they probably haven’t been watching expenses closely. Their P&L is probably dominated by payroll and rent. I can’t help but feel that programmers are drastically overpaid, which is a symptom of the same issues, that there’s a lot of other people’s money chasing a finite supply of techbros.

    The reason I think programmers are probably overpaid, by the way, is the number of man-hours they allegedly put in, versus the quality of their output. Reddit is a particularly shocking example of this.

    In any case, the other people’s money doctrine is to grow into profitability, which means burning money on spurious shit until some magic happens. Not exactly a winning business model.

    There is a kind of subtle technical problem with karma, which is (technical) problem of trust. I haven’t looked at the Lemmy spec, much less the source, but decentralized systems always have an issue of, who can you trust?

    Let’s say I want to have a user account with inflated karma for some reason. I can spin up an instance and simply assert what my karma is—and if I need to, I can create a bunch of fake accounts on my instance and create a bunch of fake posts and comments and assign fake karma scores to them, so that it can be audited.

    Now if other instance owners get wise to what I’m up to, they can defederate me. But this creates a few immediate problems, including the problem of adding more administrative load to instance owners generally. The bigger problem is the witch hunting that could ensue, if a culture of karma were to develop as it has on Reddit.
