Trash generated in the household per cup of coffee, you mean. I wonder how much waste is produced by the whole supply chain of coffee beans -> your home? It's like that electric car thing where you still need to generate power somewhere, and if you're not using clean energy, you're just moving the location of the pollution.

Okay the cups are probably greater magnitude of waste but still, unused coffee does have a higher cost than just "pour it down the drain".

Maybe with more of a PC bent, but I'm not sure how I'd pull that off without a big stash of old hardware. Probably worth it for Doom and Quake, but the real gem will be text adventure games. Sitting on my dad's lap while he played them was a big part of how I learned to read.

I think the party line is that DRM is onerous and hurts paying customers, and that sometimes a legitimate owner of the game will also need to crack the DRM to make it work on their own weird computer. I don't pirate things, but I also don't buy things with nasty DRM, especially the always-online checkers, and I think many people here are the same.

Are you crazy? Lots of places--most notably comment boards on news sites of every political stripe--are known for having a bunch of sockpuppets who collectively flag posts of people they don't like. Sheer volume lets them silence opposing opinions.

That's one thing Slashdot got right with metamoderation...probably people who are known to do that, don't get mod points again, and only active users get mod points at all (so sockpuppeting takes more effort than you get benefit).

Individual hardware is the cheap part--although it does also need to be pretty goddamn ruggedized.

Departments need new infrastructure: Servers, docking stations, stuff like that. No it's not as easy as plug it in with USB and drag and drop your files--you want this to be a lot more secure than a mountable media drive. Infrastructure is an ongoing cost too, especially with public record requests.

Training isn't zero, either. Not only do you have to teach people how to operate them (and these aren't all technical people, which means that either training is nontrivial or that docking station really is fancy and expensive), but you also need to teach them policy, really drill it in there. Call it four hours of education and training per user, and the number of users is pretty close to the number of cameras. It's paid training time, so you're covering their salary, management, the organization per-department of those training sessions, hell probably research to make sure you're giving effective training... Look, training and meetings suck, but doing them _right_ is important and it's _expensive_, and you get what you pay for.

The cost sounds realistic to me.

Personally I'd be happy to hack my car's windows in the opposite direction. On the driver side only, if you tap "up", it rolls up all the way--you have to hold it down for it to not do that. Which means if you want to adjust it a quarter of an inch, you have to go down and then up, or up too far and then back down.

If you had a program that could generate a scale invariant hash of an image, and given a command line tool that could tell you the resolution of an image (which exist, just don't know the names), I'm pretty sure you could do that in a single line in bash.

Wouldn't be surprised if there was a program that generated an image hash. Even better if it generates a value where stronger features are higher bits and smaller features (that could be lost in scaling) are lower bits, so you could truncate and compare? That might be too fiddly.
