  • 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.


  • 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.


  • 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.




  • Not an expert, but my gut reaction is not really. The panels themselves are largely glass, aluminum and silicon, with fairly small amounts of doping agents. There are electronics but since they’re outside they’re largely encased in something, wiring which would be plastic and copper or possibly aluminum, and then the structure itself which is going to be steel and concrete.

    Solar panels are significantly more sturdy than one would think given they are essentially a giant piece of glass. They’re usually rated to 12mm hail or more, which would normally absolutely devastate a crop. They don’t really go bad either they just become less efficient over time. There’s no moving parts to wear, no liquids, and in some designs very little in the way of electronics to go bad.

    Essentially, I wouldn’t be surprised if there would be more harmful contamination from a diesel tractor driving around in the field or from a nearby coal power plant than from any kind of solar array as long as it didn’t have like, lead legs or something.

    That being said, these kind of projects have been shown a lot but they’re unlikely to be used in most large scale farming - they usually interfere with any machines used to plant or harvest, and are only really well suited to a few crops. Parking lots are a much easier target for this type of solar project.
