The "programmer on the streets" should not be writing crypto code; it needs to be written or at the absolute least audited by specialists. And they have the expertise to understand these things; it's their job.
Read your own quote. Going in an unlocked door to take a look around is not "Breaking and entering dwelling house with intent to commit other misdemeanor."
"Vacuum of space" isn't just a figure of speech. The average density is about six atoms per cubic meter. Yes, occasionally a spacecraft will hit something (and frankly it makes very little difference whether you hit it at 0.5c or 0.1c, neither is going to be survivable, so the relevance to the GP's point is minimal), and it will be tragic. But space, on the whole, is very big and very empty. Most interstellar voyages would be perfectly fine without taking any precautions.
Has this actually been experimentally verified? I mean, I appreciate the purity of the theory, but it seems to give rise to problems (e.g. an object lower in a gravitational potential well has less energy than it did outside, so must it also have less mass?)
Sure, it came in a very nice sales package with a civilian agency and a great morale booster but the reason it passed was that it created lots and lots of high tech research and equipment of military value.
"The reason" is hardly accurate. It was voted through by a large group of humans with many differing agendae, and while there were doubtless many who were convinced by the military side, there were also those who genuinely favoured the aspiration to greatness. And I know for a fact that most of those presently working at NASA are doing so for those reasons, not the military benefits.
If it was about "aspiring to greatness" why would the russians break their back trying to keep up with it?
Oh, yeah, I forgot, the Russians aren't allowed to aspire. They barely get to count as humans, really.
I happen to think humanity is a good and worthwhile thing. I think a universe with humans in (or human-like aliens, which is what the descendants you refer to will be), is better and more interesting than one without.
On the flip side, if you don't think humanity is something worthwhile, then what is? Certainly not art, if you don't care about there being anyone to appreciate it. Not happiness either, otherwise you'd be in favour of having as many humanlike lives as possible (assuming you agree that a life is, on balance, happier than the absence of one; if not, then I guess you want to exterminate as many humans as possible). Science? Maybe, but it seems a bit pointless without humanity.
If we delay manned missions to other planets/moons for half a century, it won't matter.
Sure. And if we delay them for another half a century after that, it won't matter either. And if we delay them for another century after that, too, that won't matter. And another million years...
It's not as though there's something specific we're waiting for. Sure, we probably won't be able to found successful space colonies without more experience - but the only way to get that experience is to try first, and fail a few times. If we really want to make progress towards getting off this rock, we do so by starting, right now. Otherwise we as a race end up like my dad talking about how he always plans on fixing the shed someday, maybe in another ten years.
OK, well I'm glad that we can agree that the presence of Opera's servers adds some security, including authentication
If Opera's servers do the authentication then that's inducing a huge security hole - anyone who can spoof being Opera's servers gets full access.
If you find a system that protects against all known and unknown attacks, by the way, please share it.
There's no system that protects against all attacks, but there are certainly ways to protect against unknown attacks - the principle of minimal privilege, and things like base address randomization, DEP and the like all protect against some attacks even before they're known. Running your opera under a separate user with very limited privileges would give a substantial improvement to your real security; passing connections through opera's servers doesn't as far as I can see.
In all seriousness, no. They have to let enough pass through that people can download a general file from your computer, so they can't adopt a default deny/whitelist policy. So while Opera will be able to pattern-match known attacks, that doesn't actually increase security substantially - assuming you keep things up to date, you're protected against known attacks anyway, it's the unknown ones you have to worry about. And Opera's intermediate servers aren't going to be able to do a thing about them.
if you are trying to get your software raid to run this, you'd better get a really nice processor
No, you really don't need to, not these days. Modern processors are so fast (and have so many extra cores) that you won't even notice the overhead from software RAID. I'm running a 7-disk raid5 on a two-year-old processor and it uses maybe 5% cpu at peak writing to it (that's when I'm maxing out my gigabit network).
Actually, you are breaking the law. Streaming makes a copy. Not that I think it should be so, but that's how it is.
Streaming makes a copy, but it's a purely transitory copy the sole purpose of which is a legitimate usage. Which even in the UK, with the smallest set of fair use rights imaginable, is still explicitly legal.
"Toy" is unfair; it's the correct tool for certain tasks. I find myself using the "web server" built into the KDE system panel (kpf) a lot more than my apache install, because most of the time I just want to put a particular file on the internet so I can link my friends to it. For that sort of thing, unite is great.
Nothing, but your web browser will have all the "no looping", "no animation" and "no sound" options that the GP wants. That's where it differs from flash.
And seriously, how cool would a second Incredibles movie be?
Pretty poor, I would think. I don't get people's love of The Incredibles - making a dumb action film in CG doesn't make it any less of a dumb action film. (And the CG wasn't that great either - in particular, the water looks terrible)
Have you tried running japanese windows? MS may take its backwards compatibility seriously for US programs, but in Japan one hell of a lot got broken in the 9*->2K/XP transition.
Nope, I say that discarding one of the coordinates in either Cartesian or polar coordinates just because they're useless is a human construction. Altitude magically pops up again when it becomes relevant again. The Earth is in 3D, no matter how you look at it. You have to discard something for it to only be 2D.
Ok, yes, but the point is that you don't for black hole entropy - the 3D structure is exactly determined by values on a 2D surface; it's theoretically impossible for two different black holes to have the same values on that surface but somehow different entropy "inside".
(Something I'll mention because it seems relevant: the string theorists' view that space is 10D but looks 3+1D on large scales is very much analogous to the surface of the Earth being 3D but looking 2D on large scales)
Same thing for a particle's position and momentum, each are 3D values, not dimensions, because they can only be one value at the same time.
At a particular instant obviously the particles will be in one configuration - a point - which is indeed 0-dimensional. But that's just a single point in the space, just as for a particle moving in space, its current position is a 0-dimensional point in 3-dimensional space. Suppose we're considering the evolution of the system in time - the particles are moving around according to some trajectories. Now, the obvious way to view this is as a set of N different trajectories in 3D space. But we can also, absolutely equivalently, view this as a singletrajectory in 3N-dimensional space - and this representation has advantages for certain problems.
But the subject is complicated. Sure, you could expand out all those definitions - say what negative curvature means, and what a Lorentzian spacetime is and so on. But all you'd do is make the introduction much longer and harder to read for people who do know what the terms are. And for people who don't understand the terms, the links are presumably right there.

Just set your SDL_VIDEODRIVER to aalib (or better, caca, for colour). Ascii frozen bubble can be quite fun.

I'm still using a CRT; it was £5 and it goes up to 2048x1536. Let me know where I can do that with an LCD.
Uh, what? No-one should be using NAT. It breaks the internet.
Mine's five years old and going strong.

No.
Yes, and any sensible browser design would do that. Functionality should be in the program itself. /Opera user
Nothing, but your web browser will have all the "no looping", "no animation" and "no sound" options that the GP wants. That's where it differs from flash.
Terrible. They rely entirely on marketing and placebo effect; actual sound quality is if anything worse than your ordinary off-the-shelf.

Have you tried running japanese windows? MS may take its backwards compatibility seriously for US programs, but in Japan one hell of a lot got broken in the 9*->2K/XP transition.
Huh? Most japanese programs run fine under wine. Many of them better than they do under modern windows. Are you setting your locale right?
