  • I’ve thought about this for dogs. I’ve never had a cat, but some of this probably applies, with the complication that they have a somewhat sour temperament as well.

    It’d be nice on one hand, because I could say “chocolate will kill you, don’t eat it”, and they would know I’m not just being a chocolate-hoarding bastard. On the other hand, they couldn’t get away with pooping in front of everybody. They get leeway on things like that because of what they don’t know. It seems like a slippery slope where, yes, they would end up being treated more like older human children or human adults, and maybe that would spoil the cuteness a bit.

    It’s worth noting, I think, that historically dogs were expected to work for the most part. When food is often scarce having an extra mouth to feed for fun is conspicuous consumption. Often dogs were the food, too - we’re the weird ones eating pigs but never contemplating eating dogs.




  • I am not an engineer, but I imagine keeping multiple DC motors running efficiently/in sync together while outside influences change by the second isn’t easy.

    It’s easy. I’m not a professional engineer, but I’m close enough to know this one.

    A typical phone CPU can make adjustments to an output many tens of millions of times a second. It might be “only” thousands for the 10 cent toaster CPU. If it had to model and predict the road ahead somehow, that’d be harder, but just responding to changes as the wheels hit them requires some trig operations at most.

    As for the other bit, electric motors are way, way simpler than IC engines, just intrinsically. It’s a clever arrangement of magnets, vs a block of metal that has to produce and withstand constant fuel explosions using barely-standardised fuels, and then convert the resulting energy into rotation at the gear ratio of your choice, and do it for years without breaking. With electrics, the magic is all in the battery chemistry.

    Oh hey, thanks for Lemmy!

    Yeah, I’m a bit horrified to learn that Cloudflare is the crytographic endpoint for clients. I’m wondering how much stuff I’ve let them see unaware now. Because obviously nobody would voluntarily sign up for this kind of security bad practice. /s

    They’ve gotten a lot better over Tor - that’s the main thing I’m thinking of, actually. I used to give up most of the time when captcha’d, but now with the JavaScript based verification I pretty much always can get in, even on mobile.

    Most providers don’t give a shit about Tor, or actively try to block it. They actually went out of their way to make it easier.



  • The point, for believers, is just to know stuff the sheeple don’t and feel superior. It’s a smug club, they could have picked anything to be contrarian about. It’s unfortunate that they’ve picked a very measurable thing, so they occasionally self-own with experiments. It doesn’t change their mind, though, because being right isn’t the point.



  • The problem is that it takes a lot of computer power needed to run an EV. Battery management, power management, motor control, etc. Requiring that much computer power makes it a cheap and easy decision for car makers to just make everything part of that system.

    How much does that take, exactly? It sounds like something a cheap microcontroller that you might find in a dumb appliance could easily do.

    The thing about screens being easier than n custom physical buttons is true, though. I’m waiting for someone to put a haptic display in a car so the safety problems are somewhat ameliorated.

    What’s the problem with CloudFlare? They’re trying to make a profit, and so in the long run are the same as anybody, but every interaction I’ve had with them recently has left me impressed.

    Edit: The answer is that the way their thing works nullifies HTTPS.




  • Is it? Oh, I didn’t realise. I’ll cross that out.

    Yeah, it looks like the main evidence is that there’s a mention of a similar formation to testudo being seen in western China a couple decades later, and maybe some Roman-style fortifications. According to Wikipedia a large number of prisoners were sent to Merv somewhat nearby, so it’s all very suggestive, but definitely no smoking gun.
