It's possible that I'm not familiar enough with it, but in my experience OpenSCAD makes the vast majority of projects take way longer compared to non-scripting-based CAD software. I learned Onshape for a class and haven't used OSCAD since. (though it definitely still has some niche uses)

AV1 is very efficient (around twice as good as h264), but a filesize that low was almost definitely because the default encoding settings were more conservative than the ones used to encode the blu-ray. The perceptual quality of that 1.5gb file will be noticeably lower than the 44gb one

I've never administrated a Lemmy instance, but I can't shake the feeling that the traffic and activity that would generate would be a massive blow to the infrastructure we have right now. I can't name anybody at the moment, but maybe we should start with someone a bit smaller?
