  • aren’t you still limited by ambient air temp because the hot side of the Peltier needs to be cooled by air anyway?

    No, that’s why the baby fridge works. The peltier TEC in the fridge can produce temperatures below ambient, but generally not below freezing. Computer chip TEC coolers would go farther and push more power through the TEC and do things like water-cooling the hot side instead of a little fan.

    The reason they don’t get used anymore more complicated. It’s my understanding that basically TECs have a sort of limit on the amount of heat they can push from the cold side to the hot side, because moving more heat means more energy used and thus more waste heat. Apparently most modern chips are past that limit. IIRC, TECs can only move something like 100w of heat - past that and they start to heat themselves up because of waste heat. Modern chips can be like 300w.

    Sub ambient cooling also comes with a bunch of issues like condensation, so no one really uses it day to day. Also, chips are run so close to their limits now that cooling like that doesn’t get you nearly the performance difference it once did.


  • The light is immaterial (lol) to the holograms existence. They are only solid via fancy forcefield transmitted from the holo emitters. For all intents and purposes they seem to only exist as programs within whatever computer operates the holo emitters, whatever or whatever that may be. The only limit on where they can be is the speed of the computer system and links within it. They can send holo programs between the alpha and delta quadrants, but are limited by the speed and this can only send smaller programs. The mobile emitter often gets transported, but that’s because they only have one. If the doctor is going somewhere with holo emitters they don’t need to be transported and can just be data transferred.

    Personal rant follows:

    !The whole hologram plot in Voyager is honestly poorly thought out, and it basically feels like if you followed their logic Chat GPT would be a protected federation citizen. I get that the writers wanted to give the doctor legitimized personhood, but it feels like they forgot to think about what that would mean for literally every other hologram. !<

    !Like, they give that one species holograms to hunt, does that mean they invented a species doomed to be reincarnated as prey forever? Is, Moriarty sentient, and if so is trapping him in a simulation moral? If they just run a hologram long enough does it gain sentience? How are they testing for this? Does that mean Vic Fontane is sentient even though he probably would say he isn’t? What about that weird Irish bartender Janeway does - fair haven ran for a while, how long does it take? If you run a training program are you committing infanticide? Is turning off a hologram even moral?!<


  • There’s a pretty large combination of factors that went on from what I remember. Partly it just plain didn’t get that hot that often in the UK or France back then. Partly they wore entirely different undergarments that layered to keep sweat off their actual clothes and keep them cool. Partly the summer clothes were often flowy or puffy which helped move air near the skin. And partly the fabrics they wore were different. Things like linen and cotton were the go tos. Even the linen itself was different, modern linen has shorter fibers and is much lighter.

    After the great renunciation (when men started wearing the modern(ish) suit) you start to see a lot more references to taking off layers either to cool off or to keep them clean or whatever. You also start to see variations in really hot places like the American deep south and Bermuda to deal with climates that get way way hotter than Europe with its nearby seas and cooling prevailing winds.

    Please note that all of this may be wrong and I am entirely going off what I can remember off the top of my head.












  • To be honest, they seem to be taking a very media literate approach (impressively so, they definitely learned some stuff about YouTube and how to do this kind of thing) to this whole thing, so I kind of get the “farming for views” stance.

    But I get it since that means they are actually getting traction instead of just being a thing that drama YouTube talks about for a week and gets swept under the rug. The video notes he’s a very powerful figure in a relatively small town, so they need media pressure on their side.


  • Ill post this comment here too since it’s the same video, but you might want to put a content warning on this video, it’s pretty rough.

    The first video is largely about him running illegal lotteries, which is pretty terrible given the scale they operate at, but it’s something that the average person might not know about or really think about it being essentially child gambling.

    This second video is an interview with a former employee who was put in solitary confinement for a video that never made it to YouTube because it was actually just them torturing him. Like, legitimate Geneva Convention war crime torture. Constant noise, no idea what time it is because you can’t see the sun, constant lights so you can’t sleep, constant monitoring, and him running until his feet bled.

    If any of it is anywhere near true they need to be sued off the face of the planet in addition to going to prison.

  • Custom keyboards took off because of mechanical switches. Back in the day people wanted mechanical switches because they last longer than membrane ones, and so you wound up with a bunch of companies producing relatively easy to manufacture mechanical switches. Those switches all felt and sounded a little different so you got people who wanted a specific feel and sound and it grew from there.

    There hasn’t really been the same push with mice because even really cheap ones work really well. Optical sensors are way harder to produce than key switches, and while there are a few different ones on the market other than dpi and polling rate they kind of all act the same - it kind of either tracks right or it doesn’t. There’s no differentiation unlike switches that are “tactile” or “linear” or “scratchy”. And because of size restrictions you can’t really have the same kind of switches as keyboards use for the buttons. And unlike the really niche keyboard people who do their own PCB and machine their own case, making a good mouse on your own from scratch is way more difficult. They’re weird shaped and it’s much more difficult to change things like optical tracking algorithms compared to macros on a 40% keyboard. You can do a run of 100 super niche keyboards and make it work, but just the injection molds for one mouse mean you need to make 10000, which stops it being a project and makes it a business.

    There are premium mice manufacturers, but in general they either are going super light, super ergonomic, or super functional - and honestly they have a hard time competing with a company like Logitech that can produce really similar features for a fraction of the cost and have a decent reputation to boot.




  • This game is great. The runs are relatively short, a full run only takes 20-30 minutes; and the individual fights are only a few minutes long, so it’s perfect for a mobile game. It seems simple but as you unlock the characters each one is more complex, and then each character has a bunch of challenges that pretty heavily change how they work again, so there’s more content than meets the eye.

    My only annoyance is there’s no save file system. They get around it by just letting you unlock whatever you want in the menu, which is an ok but not perfect solution.

    There’s also a web based demo if you need sold on it. I don’t know if it works well on phones, but the game itself runs great.
