  • 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.


  • 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.


  • I believe you can change the scaling algorithm obs uses? Right click the source and go to “scale filter” is what Google is telling me, not at a computer right now. I think it defaults to bicubic which should be ok though? The switch does its own internal scaling a lot of the time and that can look pretty bad though, but unless you get into some serious shenanigans that’s basically baked in.



  • As far as I’ve found, they’re both right. You shouldn’t have to wash your mushrooms, but it’s not a bad idea if you’re not buying fancy mushrooms.

    The generic button mushroom variants you’re probably getting at the grocery store are grown in compost, which often contains some manure - ie poops.

    But before growing mushrooms it’s pasteurized. Mycelium is picky, and fairly easily out-competed by other stuff, so to make sure you’re just growing mushrooms and not bacteria you basically have to sterilize the medium they’re grown in.

    But those mushrooms are often grown in open beds, and harvested by hand. And that means they get that poop dirt right up on them. Will it immediately give you super botulism? Probably not but it’s still kinda ick.

    Fancier mushroom varieties from smaller cultivars are the ones that actually don’t really need washed and often shouldn’t be. They’re grown in highly sterile environments and they fruit out of a container, so they never touched the poop. And that’s if they even used compost - lots use straw or wood.

    If you do decide to wash your button mushrooms it’s not a big deal, they aren’t actually sponges, and they don’t absorb as much water as some cooking shows say. If they get soggy it probably means they’re old, try putting them in the fridge for a few hours uncovered. It’s basically a dehydrator.


  • It might be important to put into context that Jon is warming up the crowd before the taping of the show in this clip. Yeah, he probably misses the mark on exactly what was asked, but what is he supposed to do at that point? He’s warming up the crowd. Going out and saying, “journalism and by extension traditional media is dying a slow and painful death at the hands of software companies that don’t care about truth or art using dangerously manipulative techniques and the consequences of that are likely dire for the future of society” isn’t exactly setting the mood they’re going for.

    Given the traction this clip is getting it really wouldn’t surprise me to see a more nuanced take from him in a while that has had more than almost zero thought put into it.




  • Thank you! My God, the amount of holier-than-thou “it’s your own fault” in this thread is mildly infuriating in and of itself. Auto save and versioning have been a thing in Word for at least 8 years, probably over a decade but that’s the first version mentioned in their docs, and I struggle to think much software I use regularly that doesn’t have some form of it. Hell, even the new Notepad on Windows keeps your changes when it’s accidentally closed.

    I like most open source software but this sort of attitude in the community and what seems like an absolute disdain for any UX concept from the past 20 years makes me very hesitant to recommend it almost anyone outside very specific technical circles.


  • Kind of? But hot take - their format is actually better for flat content. They seem to want people to use their “spatial video” format which seems like it can be just two videos in a QuickTime or MP4 container. It wouldn’t surprise me if you could just use ffmpeg to convert whatever into their format pretty dang quickly. It’s actually just MV-HEVC.

    Most 3D video right now is one video track with two distorted videos either side by side for flat or 180 content, or top and bottom for most 360 content. It gets encoded and played back as standard flat video and then the player does the splitting and dewarping for the headset (or for flat just correcting the aspect ratio). They don’t seem to support doing any of that in their built in player.

    Instead, with MV-HEVC, they encode one eye as the “main” video track, and do deltas to get the other eye, giving you way better resolution since you aren’t splitting the frame in half, and better efficiency since you aren’t encoding essentially the same image twice (theoretically you could have a codec that could couple copy a big chunk of the frame like that but I’m not aware of any that actually do). It also means if you play it back in 2d you just get a normal video instead of a weird distorted mess, and you can swap to the other eye if you player supports multi track video. They also do some clever stuff with captions in 3d too.

    It doesn’t seem like they support any sort of immersive 3d video (i.e. 180 or 360 degree fov) in their player at all, but I haven’t looked at it a ton. I mostly just took a glance at their developer stuff. It seems like a very apple thing to do since 180/360 video is difficult to do right.
