@leptonette: Nice screen name. However, I feel obliged to point out that black body radiation is quantum mechanics, and is the origin of quantum mechanics, in fact. Without quantization of electron energy levels, black-body radiation would be infinite power.

@MercerCh00x: It's about support structure. If you're a lone nutter, it's hard to get your hands on everything without arousing suspicion. But for every person that's sympathetic to your cause, the difficulty cuts in half.

@Korrupt: And did the TSA catch him?

No, the problem with 'national opt-out day' is the 'day' part. If you think the system is an infringement on your rights, opt out every time you fly.

@The Dewd: Nicely demonstrated.

@OverThereInThemTrees: A back of the napkin estimate tells me that if you stick a big block of copper in the way, this will melt a 5mm blob of it... about the size of a small ant. Tungsten melts at a higher temperature, but has less than half the thermal conductivity. You'd need a layer of tungsten about twice as…

@OverThereInThemTrees: I can tell you the actual temperature without having to measure a thing: it's ~5750C (9750F), the same temperature as all sunlight hitting the earth.

@Nick Burns, Your Company's Computer Guy: Graphite would burn. The most likely thing to survive this would be a large block of copper.

@Ahubbuch: You're focusing light down to a very tiny point. Yes, it can get very hot at that one point, but only at that very small, single point. So while the temperature at that point is very high, there's still not that much actual heat flowing into it.

@OverThereInThemTrees: Except the figures in video were in Celsius, not Fahrenheit.

@Nick Burns, Your Company's Computer Guy: They were talking in celsius. 6400F = 3500C, which is how hot the focal point gets.

@Ioncloud9: It's a rocket being launched from the US, returning to the US, through US airspace.

@Slinkytech: There is a fair use defence to trademark infringement. You'd probably be okay with fuckfacebook.com, although you might end up the recipient of a sternly worded letter.

@92BuickLeSabre: If they want their trademark to be worth anything, they've got to defend it against dilution. Which means either Apple licenses 'Face' from Facebook, Facebook sues Apple for trademark infringement, or they do nothing and Facebook loses the trademark.

@Antubis: Your example is an ex post facto law, and is explicitly forbidden in the US Constitution (article 1, section 9). And no, Facebook can't go after Apple's previous use of the name 'Facetime.'

@redman042: Not everyone's. I rotate my monitors into vertical when possible; it's a better format for working with text.

@gffuentes: That's why there's a rule about bringing liquids on-board.

@Cris Lehman: As much as I agree with the sentiment, I hope you realize the TSA aren't screening for drugs. They're not allowed to.

Didn't Mythbusters have one of these on their show years ago?

@A Magician Named Gob: DLNA is a standard, not a user experience. If a DLNA device is hard to setup (and most of them aren't at all), that's a fault of the device.
