  • You can put quite a lot of nines after the decimal point if more than 99% of people die without humanity reaching its lowest population in history, so the post you’re replying to is right that humans are likely to persevere, and knowing humans, there’s a good chance that if industrial civilisation starts again (which is less likely - you need lots of accessible cheap coal to make it worth putting up with rudimentary steam engines long enough to develop good ones), lessons won’t be learned and we’ll pollute ourselves to death again.


  • People only pass out from head impacts if the brain damage is bad enough to be permanent, but don’t always pass out from receiving permanent brain damage, so this is really bad, too. I’ve read (but probably on Reddit rather than a real source) that people pass out from hypoxia well before any permanent damage, so choking people is safer, especially if you learn to do a blood-choke properly so don’t risk crushing their windpipe. Alternatively, lure them into an operating theatre where a qualified anaesthetist who knows their weight and medical history is waiting, as they’re really the only people who should be making other people pass out.


  • They don’t have a Linux version of their launcher, and don’t have a system to automatically configure Wine/Proton for games without native Linux support, which is most of their library. There’s nothing in the licence of Wine or Proton that would stop them just reusing Valve’s work, which is why third party launchers like Heroic can do it.


  • Legally, you own a copy of a book if you buy the book even if you don’t also buy the copyright for the book, so wouldn’t be allowed to make copies (beyond the single backup copy your allowed to make in case the first is damaged that you’re required to destroy if you ever stop owning the one you bought). This also applied to physical copies of video games, at least when they were new. In the US, this is part of what’s known as the First Sale Doctrine, but other territories typically have stone equivalent even if it doesn’t have a name.

    About a century ago, book publishers tried putting a licence in copies of books and claiming that if you bought them, you were only buying the licence, but stopped after courts decided that you’d still bought a copy of the book and a copy of the text of the licence, but hadn’t become party to the licence. When game (and other software) publishers tried it later, they were basically just allowed to, even though there’s not really anything that makes the First Sale Doctrine any less applicable to games than books.




  • Children are born loving their parents, and should figure out pretty quickly that their parents love each other (sometimes even if they don’t). Understanding the gist of marriage should therefore come pretty naturally to children, whether gay or straight. If they’re perceiving straight marriage as normal and gay marriage as odd, then that’s something they’ve been taught rather than their natural state that needs protecting and preserving until they’re older.




  • Some things off the top of my head are:

    • you could set the temperature to a number of degrees via a numerical display, which would be much harder to implement without a microcontroller.
    • maybe you could have PID control over the compressor rather than bang-bang control, so the temperature would be more stable.
    • these days, a bimetallic strip costs more than a microcontroller and a chip thermometer, despite the chip being much more accurate.

    All of this only requires a really dumb microcontroller, though, not one with networking. I don’t see how that could be useful until your fridge could magically track what it contains so you could ask it if you needed to buy stuff while you were shopping. I don’t think we have the technology for that yet.


  • It only applies to movies and because they’re expensive enough to make that the major titles almost all are things funded by a few major producers, and the investor-first approach has been pervasive long enough that the major shareholders of the studios are that kind of investor, so they pick people to be on the board who agree with them, and the board selects C-suite staff that are good at talking to investors rather than that are good at making their company produce good movies. The kind of movie they then want to make is the kind of movie that costs a lot so they can tell investors that it’s the most expensive ever and therefore the best ever and therefore will make a morbillion dollars (and also says nothing so it offends no one and can be marketed to everyone) rather than making lots of mid-budget movies that might make many times what they cost or might barely break even or might become a timeless classic that makes a profit for decades. If their morbillion dollar movie flops, but the share price is higher than before it was made because investors expecting it to do well invested, the company’s still considered to be better off, and they’ll happily do it again.


  • There’s currently much more money to be gained from attracting investment than there is from generating profit, so companies that don’t prioritise selling to investors over selling to customers just won’t get as big, and the feedback loop ensures that investors who invest in things that other investors will invest in later will have more money to reinvest later than investors who invest in companies that can make a profit. Historically, investors who invested in companies that couldn’t become profitable lost their money, so couldn’t invest in other things in the future. The system kind of does do what it’s intended to, and efficiently allocate capital to where it generates the most return, but that’s become decoupled from the implicit goal of most effectively providing goods and services.

    If I had to guess at the root cause, a good candidate would be that after the 2008 financial crisis, when quantitative easing was (successfully) used to stop nearly everyone losing their livelihoods by ensuring investors had access to enough money to avoid feeling pressure to pull out of all their sane investments and in doing so collapse all major employers, because it was never undone through quantitative tightening, there was enough excess money sloshing around afterwards that investors could afford to risk investing in dumb shit, and dumb shit could attract enough follow-up investment later that the early investors were rewarded.



  • Dextrose is specifically right-handed, which is why it starts like dexter, the Latin word for right (and the rest is just ose, which means sugar, so the whole thing just means right-handed sugar). It got its name because when it was first identified as its own molecule, it was because it polarised light to the right, whereas l-sucrose, which had already been identified, polarised it to the left. Glucose is also possible as left-handed l-glucose, although it doesn’t occur naturally in earth life.


  • And it was functionally the second bullet point, with all instructions being emulated, so the emulation software was what the CPU really ran. You can do emulation of a CPU on a compatible CPU, but it doesn’t generally end up faster than doing it on an unrelated CPU. E.g. the code you’re emulating will use all the registers the CPU has, so you have to maintain a mapping from emulated registers to real registers (and because you need some registers for the emulator, some emulated registers necessarily must spill to memory), and the code you’re emulating could use any part of the address space, so you’ve got to map from the emulated address space to the real one. Every instruction potentially needs some alteration, so you can’t just run them as-is. There can be time savings, e.g. x86 has all aligned writes under 64-bits be atomic, so on unmodifed Arm, you need to insert extra locks, and if x87 instructions are used, they don’t quite conform to IEEE754, so would need doing via many integer instructions instead of a single float instruction on non-x86 platforms, but there can also be time savings from using a different architecture, e.g. Transmeta’s CPUs had way more registers than x86, so could give all emulated registers a real register and still have enough for the emulator itself to use.


  • That’s why it is useless to expect CEO’s, politicians, business owners, etc, to act according to your morals.

    I don’t expect them to act morally - we live in a system that puts immoral people into positions of power - but I also don’t have to make excuses for those immoral people acting immorally. I can expect that the system produces bad outcomes because it’s put immoral people into positions that can influence the outcomes, and explain that as the behaviour of the system, while still condemning the immoral people for acting immorally. At least some of them do have a sense of shame or a vested interest in appearing likeable, so normal people do have a degree of influence when they complain enough.

    To be honest, I’m hardly familiar with Dolly Parton, but wasn’t she famously silent on controversial political issues?

    There were plenty of things that she spoke out on (or directly acted on) that had no good reason to be controversial, but nonetheless were, e.g. personally funding COVID vaccine research and giving books to millions of children. She often wasn’t vocal about the causes she supported, as the goal was to get good things done with the unspendable amount of income she was receiving rather than to spend money to improve her image, so it was often long after the fact that people would discover she’d been the benefactor making something possible. She’s often listed as the example of a good billionaire because she wasn’t a billionaire, but would have been several times over if she hadn’t given away so much money.
