    "Your world view is rather depressive."

    How about changing that to "requires funding beyond the life of current political trolls", and an asteroid that would be hitting earth sooner than that? There's no "safe harbor" for no kind of personal pension fund that's safe against an asteroid impact, and even a stupider-than-average politician (or the lobbyists manipulating him) understand that...

    Nope according to quantum theory they didn't exist before because we couldn't measure them. Or was that intelligent design? I always get the two confused. Both require the belief that in the beginning there was nothing and then it exploded.

    Ah, but in quantum mechanics, once we observe something ("cause the the wave function to collapse into a determined state", to be technical), we retroactively determine it's existence at least as far back from the observation as uncertainty principle allows us to theoretically calculate.

    So even if an asteroid doesn't exist now, if we observe it as a fiery ball hurtling across the sky and getting rapidly bigger, it's existence will get retroactively established back through the history of the universe.

    The only protection is to observe that an asteroid is not in a certain location, and thus snuff out the possibility of one popping up there magically just to annoy (and kill) us. Once we have observed all possible locations where a rogue asteroid could be, we can be sure none will pop out of nothingness.

    Or alternatively, if you think magically appearing asteroids are not a plausible idea, you can think the asteroid was there all the time, but that's boring... ;-)

    This will probably confuse the paleontologists in the future, since they'll see a mass extinction during a crossing of the galactic plane, but won't see any evidence at all of the impact that presumably caused it. They'll also see the evidence of a species with high intelligence, but of course that couldn't be the cause, because you wouldn't expect a highly-intelligent species to destroy its own ecosystem, right? So the extinction event will remain a mystery.

    Nah, you're thinking too positively. They'll see the mass (and subsequent self-) extinction caused by technological civilization, they'll rally the support of their society to fight it (sort of like current global warming thing), yet they'll end up destroying themselves anyway, despite their best efforts.

    Exponential population growth is a bitch, when the things that can keep it in check (disease, predators, starvation...) can be temporarily staved off by technology.

    But you are right on a point. If we were extinct two hundred years ago, nearly no evidence would remain. Future geologist would be very luck to gather a piece of glass, nothing else would remain. We'd probably disapear by then.

    Hardly. Just think of the buried stuff archaeologists are digging up today. If there were no archaeologist now, most of that stuff would still be very recognisable after millions, even billions of years, assuming it didn't get eroded, destroyed by a volcano or subducted into the mantle.

    And already a few hundred years ago we had littered the planet with stone buildings, increasingly more precisely shaped stone blocks (and bricks and concrete counts as stone here), unnatural pieces of not only glass (which you mention) but also gold and other jewellery. And it's not just in small spots here and there, just think about the sprawling fortifications and sewer and canal systems for instance, dating back much more than a few hundred years. Not to mention all kinds of large blocks of iron, such as cannons and ship anchors, which I'm pretty sure will get fossilized much in the same way as biological remnants can get fossilized (except they rust to nothingness much more slowly than even bone, so there's much more time for them to get buried). Then there are mines and other tunnels, which often are in pretty stable places geologically, and very clearly created with tools, and would be preserved pretty much until eroded all away or subducted.

    Forget variable names. It's the identical capitalization of them that makes me think twice about this.

    Capitalization of variable names is usually defined by the coding style (be it formal style guide or personal style of an experienced coder).

    Anyway, I always assumed (i)cnremental and j/k neatly followed in the alphabet.

    That's probably far more common reason than some archaic Fortran convention. Also it could just mean "integer loop variable" without any relation to Fortran, or whatever an individual programmer was thinking when using it. It's just a co-incidence that "integer", "incrementing" and "iteration" start with same letter, and it's not very unlikely co-incidence that many people used it and applied same alphabetical logic to related variables.

    Now tell me why we use i,j,k... so often.

    I use i for iteration, and the letters after that in alphabet are one logical way to do nested iteration loops.

    Except I hardly ever use single letters (sometimes x and y but that's about it), because it's a pain to grep for, and to search-replace. For non-nested loop I usually use ii, and for nested loops it's usually i1, i2, i3...

So is it like, if you're poor enough, government will keep you alive as long as you live, and if you're rich enough, your insurance or your family will keep you alive.

    I'm surprised that China doesn't go with a more aggressive stance towards the problem of HIV/AIDS. (Keep in mind this was suggested to me by my great-uncle as he was dying of AIDS in the early 90's:) After having a positive test and confirming with a second more controlled test for HIV/AIDS, have the person immediately euthanized. And before any of you try the cop out of "My relation/friend had AIDS I don't want them killed," keep in mind had we done that 25 or 30 years ago it would have saved MILLIONS of lives since. The deaths from AIDS in it's entire history would have been in the hundred thousands. My uncle would gladly have been euthanized after being diagnosed had the law allowed it.

    Eh, you're suggesting compulsory HIV tests, and anybody with positive results would be immediately arrested, and if followup test showed positive result (or perhaps, in especially in a country like China, somebody in power decided that this person clearly has HIV because of his political activities...), then *BANG*?

    And you're from China...? If a lot of people think that it's ok for government to wield that kind of power, no wonder things are as they are over there... Well, I guess it's a cultural thing.

    Which incidentally is the reason why trying to control human population is rather hopeless in the long term... Our only hope is to develop technology faster than human population grows, because if we don't, we'll hit the carrying capacity of the ecosystem. Even with interstellar travel, expansion probably is ultimately limited by lightspeed in 3 dimensions, which leads to polynomial growth of living volume, while population growth is exponential.

    IOW, we're screwed. Wether we deal with the problem intentionally, or let nature take it's course, it won't be pretty. All I can hope is, we don't hit the limit in my lifetime, perhaps not even in the lifetime of anyone I know directly.
