  • 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.







  • 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.


  • 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.




  • 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.


  • I think it’s a conflation of the ideas of what copyright should be and actually is. I don’t tend to see many people who believe copyright should be abolished in its entirety, and if people write a book or a song they should have some kind of control over that work. But there’s a lot of contention over the fact that copyright as it exists now is a bit of a farce, constantly traded and sold and lasting an aeon after the person who created the original work dies.

    It seems fairly morally constant to think that something old and part of the zeitgeist should not be under copyright, but that the system needs an overhaul when companies are using your live journal to make a robot call center.



  • capture card

    Hmm I need to do some research. I’m not really sure what these are for or what they do, but I’ll look into it, thanks.

    Sorry, probably should have explained. If you have a camera that has an HDMI or other video output they basically convert it to a USB camera.

    I’ll look into this as well. Seems like people have had focus issues though, based on reviews I saw.

    Most of the models they put out don’t have autofocus at all, you have to physically turn it to focus. Depending on exactly how your setup works that may or may not be viable - overhead cam like for playing magic probably doesn’t move much, but for video conferences where you shift in your chair it might be weird if the room is a bit darker.


  • If you already have a camera with HDMI output sitting around a capture card can be a great way to get really good image quality for not much money. If 720p is enough I’ve actually had really good success with these incredibly cheap ones: https://youtu.be/daS5RHVAl2U - I’ve even seen them at places like Walmart and Target under the Vivitar brand so they’re readily available.

    If you don’t look around locally for used Sony cameras. Because 1080p is only 2 mega pixels and many of the nicer old Sony cameras have clean HDMI output you can get kind of amazing image quality for very cheap. Some newer model mirrorless cameras got updates to run as a webcam directly off the USB port but they’re likely out of your budget and some require software. (Edit: make sure you check if the model you’re looking at has clean HDMI out - some do, some don’t, and some do with some tweaking. This site has a decent bit probably incomplete list: http://wasge.es/clean_output/ )

    If you want a more traditional webcam and need autofocus something like the Logitech c920 family is probably your best bet but the constant revisions may have added a software install. Most cameras are including software since realistically they’re all basically the same and most of the “features” are added in the software.

    If you don’t need autofocus, there are a number of companies taking Sony “security camera” sensors and slapping them in boxes with screw mount lenses. ELP and Mokose are examples but there are others. With enough light these generally look pretty dang good. If you pick one up and decide later to upgrade, it can probably live mounted up high just for playing magic, especially since there are a few 4k ones that will probably let you read the tiniest of text on the cards.
