Comment: This project deserves better than being killed off (Score 1) 185

This project deserves not to have an experienced crew sacked in its late phase, which would most certainly kill it. It also deserves the best people, and not limit itself to those who can afford to work for free. Society throws large amounts of money at fools for going round a track really fast, for yodeling into a microphone, or generating graphs from spreadsheets somebody else filled in. So if anything, those engineers are paid too little. Anyone who thinks otherwise has so little sense of priority that I wouldn't entrust him with managing two guys with leaf blowers. Why was this modded insightful? It's the most bleak, insight-less, accounting-troll-ish thing I can imagine.

It is tempting to put that nasty stuff to a civilian use, but such a program could also be an pretext to keep up the production of weapons-grade fissile material. When conservative politicians in the 1970ies were pushing to arm West Germany with its own nuclear weapons, one of the things they did was having a breeder reactor built (thankfully it never was completed). Such a thing should definitely be avoided.

mathematical laws from? If the most reasonable explanation for ours would be that someone put them there, what kind of über-laws would his world have? And how would they come to be? By that logic, he would himself most likely be part of a larger simulation! And how much resources of his universe would it take to model ours? Surely electrons or quantum states or whatever he would be using don't come free. Much less does an potentially infinite hierarchy of model universes within model universes. I don't think the idea is even new, didn't some french dudes explore this idea?

... using it as a computer monitor, try it out, and if the shop won't let you do it, leave it. I bought a Philips tv with that intention, and it has several kinks that make it less suitable than I hoped for. Not only does it take longer to start up than my computer to boot, but also the menus are terribly cumbersome, and the tuning options for color, resolution etc. are not well suited for computer use.

Comment: I'm not sure how much stereo is in that vision (Score 2) 79

Indoors stereo vision is so hard that if the DelFly actually navigated by stereo vision, this alone would be truly groundbreaking. Especially given the limited processing power on this thing. However, judging by the papers publicly available, the actual collision avoidance on the DelFly seems to rely on optical flow, and complementary, a new model of texture analysis called "appearance variation cue". Both of which do not inherently rely on stereo vision. I might be missing something from the more current papers though.
