For a great example of redundancy in action, take a look in the mirror. You have individual cells dying by the millions every minute. Your memory is fuzzy at best, your pattern-recognition in your brain frequently sees things that aren't there, and you make stupid mistakes every single day. And that's fine, because the overall system is pretty damned redundant and resilient. A mash of protein goo and calcium deposits able to sustain one of the most complex information systems around, reliably, 24x7, for an average of 70 years or so apiece.
24x7? They take mine down for maintenance every day!
Every energy production that has such a dangerous by-product is not the solution to our problem. Then again, we should think whether the hydrogen is. Don't want to sound like an asshole, but that water vapor those hydrogen-fueled cars produce is not going to vanish either.
If you use water as your hydrogen source it sure is, after the process to separate hydrogen from water becomes efficient enough.
Actually, you's probably want a multiple of 28 years, so that the days of the week line up. For a short period of time, a multiple of 7 is probably OK, but if you pass over any leap years, they'll throw things off.
That works fine for 28/56/84 year "anniversaries" but once you cross 100 things start getting wonky, especially once you cross 1582 (the year).
1995 called...and wanted to remind Apple what happened the last time they got away from their core business of making computers and operating system software.
2001 called, and wanted to remind you that Apple's core business isn't making computers and operating system software.
You put the car at freeway speeds in traffic. How about we put the GA craft in a similar situation? You're at 500' over a major metropolitan area doing some sightseeing, and your engine dies. Do you see the magnitude of the difference in difficulty here?
"Situational-awareness monitor?" Do you mean TCAS, or some sort of fantasy system you made up using an aviation term?
Also, manned aircraft don't use GPS altitude, they use an altimeter; that's one of the reasons it's so shocking there haven't been midair collisions between manned and unmanned aircraft yet. If vertical separation between aircraft is 500' and the error between GPS altitude and altimeter setting is 400' you're asking for trouble anyplace there are lots of both manned and unmanned aircraft.
The reason GPS isn't required for flight is that it's considered a "backup navigational aid" -- it's a lot more failure-prone than an altimeter and a compass. Aviation procedures are focussed on reliability before all else, and understandably so. If you're driving your Chrysler down the road and the engine decides to quit, then you pull over to the side of the road and call AAA. If you are flying your Cessna somewhere, you can a) restart the engine, b) find a suitable place to land if one exists, or c) crash the aircraft.
Had they truly been geniuses in the sense you suggest, they'd have specified the algorithm for determination of the copyright period, instead of just the value.
They left reverse-engineering of the algorithm as an exercise for the reader.
Dude, what? You're acting like "telephone" isn't a native construction in English, and that it wasn't immediately obvious in Chinese which pronunciation was the loan word, and where it came from.
Also, I'm not absolutely sure on the "telephone" example, but a lot of words in Chinese/Korean/Japanese that were imported from English in the late 19th/early 20th century were forcibly replaced with native substitutions during World War II, because we were the "bad guys" according to the Japanese who ran things in the area at that point. The word for baseball is a good example of that.
But with English -- unlike almost any other language -- you can look at a word and immediately know that its roots are in Greek, or Latin, or French, or Celtic, or whether it's a modern loan word. This has massive benefits for advanced literacy, as it means you actually know more words than you think you do, and can quite accurately guess at the meaning of new words you encounter -- which is of far greater utility than simply knowing how to say the word. Get the sound wrong and people will correct you almost immediately, so what's the problem?
Nonsense. I only know a little bit about a few languages, but off the top of my head Japanese and Korean are both much better at sorting out word origins. Japanese even has a separate syllabary for modern loan words.
In Korean, you know if a word is pure Korean (no associated Chinese character, different verb structure), Chinese (associated character, verb structure) or loan word (tend to be very long, uses Chinese verb structure).
What "any other language" were you thinking of there?
Right, but a even couple degrees worth of course correction makes ballistic intercept impossible (and greatly complicates guided intercept). You'd have to have quite the missile to be able to hit a target at 100k feet (~19 miles up) in a radius large enough to encompass the places the plane could reasonably get to in the time it takes the missile to climb to altitude.
If it's intended as a satellite-replacement in case of reconnaissance satellites being destroyed by ASAT weaponry, wouldn't there be some issues in remotely controlling an aircraft with "transcontinental" range without relying on communications satellites that would also presumably be destroyed by the point this aircraft is needed?

That's not a weather report, it's part of an airfield survey.
Sure 2000 was, but 1900 wasn't, and that's 112 years ago.

He said "magnet" not "katamari."
How about a smoke & fumes incident? I don't know how easy (possible?) it is to ventilate the cabin on a passenger jet.
Obviously it's time for a good old-fashioned War on Spam. Send in the Marines!

Very *high* temperature. Superconductors at low temps are (relatively) easy.
In the NPR interview http://www.npr.org/templates/story/story.php?storyId=15739280&ft=1&f=1003 on this topic, they did indeed mention that the cost had gone down for other telecommunications services. Repeatedly.
How about the Marshall Plan?
It's more expensive, but it's possible to send images.
"Google Earth" was taken.
Sanity, right?
Unsolicited e-mail, regardless of origin, is spam. It may not be legally actionable spam, but it remains spam.

+4 Insightful? I understand both the RIAA and Microsoft are cool to hate, but that doesn't make Microsoft part of the RIAA. Bravo, Slashdot mods.

Good point, see also: Robert Heinlein and the waterbed.
