[Technology Connections] Thermoelectric cooling: it's not great.
  • 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.

  • Can holograms be transported?
  • 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?!<

  • This rabbit isn't rule
  • 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.

  • Sky thing happen
  • Unfortunately probably not. G3 events aren't that uncommon, there's usually one every couple months. It never hurts to go look for a few minutes though. It's a pretty rough prediction, it's not set in stone. The best I've seen was a G4 and not the big G5 a few months ago.

  • Sky thing happen
  • Yeah IDK if people in the thread are actually familiar with the scale.

    I'm fairly far north and I'm considering turning off my g3 email alerts and just leaving the bigger ones since it's generally a nothingburger.

  • Long watch on war gaming, how it works, morality and its impacts on regular gaming.
  • Yeah, it feels like the entire time he's really trying to link these games to actual deaths during war that seems pretty tenuous, largely due to his own "ick" factor that "his thing" is being used by the military.

    The section in the middle where he essentially asks all his interviewees basically "have you killed anyone" is pretty awkward. Like, of course these people don't really want to talk about that. Nobody wants to go around thinking they're directly responsible for preventable deaths. It's like he wants someone to just say "Am i the baddie?" like that Mitchel and Webb sketch.

    It also completely glosses over the way that "play" is often just training for something more violent. Tag is a fun game until someone brings a knife. But there's a world of difference between "you sunk my battleship" and the Bismarck. It's like he's somehow taken the stance that video games cause violence in the most roundabout way possible.

    It's a shame because the video is good but it could be so much more interesting diving into examples about how these games actually work and are used instead of hemming and hawing the whole time over his imagined Cluedo to murder piperine.

  • It genuinely upsets me that Valve spent their time and resources on another Dota variation
  • Ok, I'm a bit out of the loop but is Deadlock actually any good? Like, most of what I've heard is that it just isn't very fun. Even though they kinda fell apart the auto battler and the card game from Valve were generally fairly well received from what I remember. But everything I've heard about Deadlock is that it's not fun, and is bringing the worst elements of DOTA with it.

    Maybe since it's barely even a thing yet, it might wildly change since that's part of the Valve MO.

  • Unifi AP behind an extra switch: 2.4Ghz network stops working after ~30 minutes
  • Ah, ok. The Unifi stuff is a bit weird like that. I recommend installing the controller on a computer if you continue to have issues. You don't have to run it all the time, just use it for config and then turning it off is fine. It'll give you way more information and control over exactly how the AP is set up.

  • Unifi AP behind an extra switch: 2.4Ghz network stops working after ~30 minutes
  • Which model is it? As far as I'm aware all the Unifi APs need the controller for config. It doesn't need to stay running unless you want a couple features for large deployments but you do need to run it to set things up initially. The Air Max / uisp lines are the ones with web based config.

  • Unifi AP behind an extra switch: 2.4Ghz network stops working after ~30 minutes
  • Do you have a continuously running unifi controller or is it only running when you do the config? Does it do the same thing with the controller opposite to how it is now (ie if you aren't running it does it do it when you leave the controller on)?

    Are you running the 2.4 and 5 as separate SSIDs or the same one?

    Are you on the latest controller and firmware?

  • I Worked For MrBeast, He's A Sociopath
  • 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.

  • I Worked For MrBeast, He's A Sociopath
  • 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.

  • [Feature Request]? Open post / community / instance with different account.

    So, this will probably be possible when the link handler is implemented, but it would be really handy to be able to switch what account you are viewing a post with. I'm guessing it would be possible to share the post to the link handler and then there would be an account selector, but it would be nice if there was a slightly less roundabout way to do it.

    I'm on a smaller instance and browse all from the anonymous Lemmy.World account sometimes, but when I find a post from community that I'd like to subscribe to I have to copy and edit the post link to get the community link to search with. If anyone knows an easier way I'd love to know it.

    How do you backup things to your server?

    So, I've found that there are a lot of ways to backup a server and anything on it, but I'm somewhat at a loss for what to use to backup everything else to that server.

    For most stuff I personally can grab the files I need and back them up using a simple SMB share or rsync or whatever, but for my SO or anyone else who wants to back up is going to have a hard time. That doesn't even cover phones - which you would want to back up fairly regularly since, you know, they get dropped. Sure, I personally can hook up tailscale and split tunnel it, and then set up sync on certain folders, but nobody else I know is going to be able to.

    In a perfect world there would be a backup app that had its own little wireguard tunnel built in that could run all the traffic from wherever to my server, and would easy to set up on Android and Windows, but I don't think that exists. So what does everyone use that does exist?
