  • Surprisingly, this even applies to black holes (i.e. Hawking radiation).

  • Hmm. I've always thought that bananas released the most ethylene; and that they can be used to ripen other fruit (or ripen themselves faster if you put them in a bag or something). ... But this seems to suggest it is apples that should be used for that - unless there's a significant difference between 'produced' and 'released'.

    In any case, I guess it's something I might revisit and reassess.

  • Yeah. I've been interested in AI for most of my life. I've followed AI developments, and tinkered with a lot of AI stuff myself. I was pretty excited when ChatGPT first launched... but that excitement turned very sour after about a month.

    I hate what the world has become. Money corrupts everything. We get the cheapest most exploitative version of every possible idea, and when it comes to AI - that's pretty big net negative on the world.

  • We're no strangers to that meme. But you know the rules, and so do I.

    This is not loss.

  • I didn't look at that until I saw your comment. And looking at it now, I see why I didn't notice it - it looks like a blurry mess. But yeah, even so blurry it is a massive hint. I reckon you can probably turn down the sensitivity on your moronometer though.

  • I guess not. Its just that when I hear 'theoretical physics' I immediately think of particle physics (and related fields). I have this idea that in most branches of physics people just say the topic, eg. astronomy, material sciences, or whatever; and don't usually specify whether they are doing theoretical work or experimental/empirical work. But in particle physics ... my impression is that people are more likely to specify. Anyway, that's just my own bias I guess.

  • I think 〉 means a very hungry (or at least large mouthed) crocodile, and > is just a normal one.

  • The lines are the crocodiles wide-open mouth... ... but yeah, I'm not a fan of this kind of mnemonic. It requires remembering a heap of details, such as which way the crocodile is facing, and does it prefer to attack the larger number or the smaller number - and how the relates to negatives... Which I think is surely more difficult than just remembering that the large end of the wedge is the larger number, and the small edge of the wedge is the smaller number.

    That said, having multiple different ways of remembering something is often helpful, particularly when getting started. (I remember having a bunch of different ways to remember which was "left" and which was "right" when I was a child. But now I don't think about any of those things anymore.)

  • Surely in theoretical physics, the most common use of > is in a ket (eg. |ψ>).

  • My computer has a problem where occasionally it will become completely unresponsive. (Mouse cursor doesn't move. Keys have no apparently effect. Whatever app is running freezes. I think its a hardware problem with the graphics card, but I don't know what. Logs at the time it freezes say "the GPU has fallen off the bus".)

    Anyway... I recently learnt about Magic SysRq. And I've been able to shutdown the computer from this unresponsive state with SysRq, R E I S U O. Where as I understand it, the "E" tells processes the end nicely if they can; and then the "I" just ends them by force.

    (At this point, I'm realising that the E is SIGTERM, not SIGINT - so that screws up the relevance of my story; but I figure I'll keep going anyway.)

    The point is, I've been using key combo with a nice pause between each key, thinking there was some chance that processes might be ending gracefully. But when I tried it while the computer wasn't frozen, the computer was able to inform me that the E and I commands were disabled. (I don't know why.) So even though I wanted to give a nice "please end" signal, in the end that just wasn't happening.

  • Idk sounds about right to me, 8%-8%. What do you expect, 8% of people carry so 50% of people have a gun on them at any given time? No, more like 8% of people have one at any given time, therefore 8% chance. Your figures seem off to me considering there are none, “nuh uh” isn’t a rebuttal.

    I'm saying that if 8% of people carry guns and there are 20 such people at a particular location, then the probability that someone in the group has a gun would be 1-(1-0.08)^20 which is around 80%. For 1 person, it's 8%, for 2 people it's 15%, and so on.

    But whatever. I can see you are firmly in the camp of 'we need good people with guns to stop bad people with guns' - a view that basically only exists where gun-violence is endemic.

  • I don't speak for the person you are asking, but for me the reason is that google is evil, and huge. They don't need my money, and I wouldn't pay them for any reason.

    I expect that if the workplace officially needed to use YouTube, then that workplace would be paying for that subscription. But if its just that sometimes someone wants to include video from YouTube in a presentation or something - then probably not.

  • Hmm.. If you say 8% of people carry guns, then surely there's a much higher than 9% chance that someone will have a gun at the scene. So something seems a bit off there.

    I'd suggest that instead of just imagining how the percentage of people carrying guns might effect these stats, it might be better to try to measure that effect by looking at similar stats for other countries where gun carrying is far less common.

  • Oh, I see. You're only counting the times when a bystander successfully intervened. (And now you're being snarky about it, rather than just saying that's what you did.)

    In my interpretation, the 113 times where the attacker left the scene are also relevant.

  • Where did you get that "65%" and "34%" from? It doesn't match the information in the graph you are responding to.

  • Yes. The GamingOnLinux Forum is shutting The forum.

  • Funny joke. But yeah, the creation, distribution, and disposal are not free - even if they are created from trees. Using two sheets isn't a big deal, but why use double what you need?

    Anyway, I'm not trying to say we need to be super-frugal with our paper towels. I'm really talking about people who just keep grabbing more and more of them until their hands are dry. I'm sure we've all seen bins overflowing with barely-used paper towels. We don't need that.

  • I just wish people would know how to use paper towels so that they don't end up wasting huge piles of them for nothing. 1 sheet is enough. You don't need 5. Do it like this:

    • After washing your hands, brush excess water off each hand using your other hand. Your hands should not be dripping wet when you reach for the paper towel.
    • Take a single paper towel. Don't scrunch it up, and don't just clasp the towel. Use all parts of the paper towel to deliberately wipe your hands. The paper towels are quite absorbent. They don't need to be 100% dry to remove the water from your hands.

    The end. If you do this, your hands will not be wet. You will not need a second paper towel.

  • I'm still using Windows 10 on my personal work laptop, and I've got to say that what you've described sounds pretty appealing. Windows 10 with most of the crapware removed, and extended support. That sounds like a good deal...

    But on the flip side, I think it's a bad idea to get an OS from a piracy site. Maybe it's all genuine and tickety-boo, but being a reputable 3rd party source is a fairly high bar. I certainly wouldn't trust a site I've never heard of to give me a legitimate copy of a better-than-standard version of Windows. Their offer to verify their own files is less than convincing. I think I'd need to be an active part of the scene to be able to trust something like that - because it certainly smells like an easy way to get back-doored.
