Eh, kind of. There's a no atheists allowed rule last I checked (A belief in a supreme being and scripture is a condition of membership), but they're not picky about what god(s) you might worship.
You say that like those are impossible obstacles. It's been a while since I rode a school bus, but the driver wasn't exactly adult supervision, and there was plenty of vandalism already. If anything, a self-driving school bus would be a positive as it would then allow the former driver to actually focus on the kids.
Not sure I agree with the idea that others could be fooled by where it's going in traffic, given that it's programmed to obey traffic laws.
Yep, I was a bit annoyed to find stuff like the Boomerang in here. Most people don't realize that losing the critical engine on a multi can be much more dangerous that losing both. Burt's Boomerang is probably one of the least ridiculous designs out there, as the asymmetric design of the wings is there to negate the adverse effects of a critical engine failure.
You're correct, OEM hot swap trays are only tool-less once it's screwed into the tray (Though the OEMs do tend to ship most drives preinstalled to their trays). The OCP stuff is designed to drop the bare drive into the JBOD/Server.
Don't have anything to link to, but you're right, everything still ends up in a 2U, technically OU (Open U, 2 inches per OU instead of 1.75), chassis. Each ODM has their own unique sled setup for the server nodes, but everything ends up in a 2OU framework for the busbar connection.
