  1. Re:And she didn't move??? on Meteorite Hits Girl · · Score: 3, Informative

    Why would you think it would be radioactive? The vast majority of meteorites aren't.

    And it's not surprising that her leg wasn't reduced to "smoldering remains." No doubt the meteorite did get quite hot on the upper atmosphere, but by the time it got nearer ground level (and went through England's usual cloud cover ;) it had shed quite a bit of both thermal and kinetic energy. And finally -- I've found meteorites that looked very much like the one in the picture, and one of the surprising things about them is how light they are. They're not solid chunks of rock; their outer surfaces are a kind of frozen rock foam, presumably because of what happens to them on their way through the atmosphere. So I have no problem believing that one of these could hit someone on the foot without doing serious damage.

    Parent isn't a troll, just doesn't quite have the facts straight. ;)

    More accurate to say that AIDS is a disease resulting from HIV infection. HIV is itself a virus (Human Immunodeficiency Virus) which attacks the key cells of the human immune system, leaving it open to all kinds of infection -- viral, bacterial, fungal, and parasitical. Drugs which fight these opportunistic infections can (and do) help AIDS patients quite a bit, but it is indeed possible -- and more useful in the long run -- to develop drugs which fight HIV directly. We have plenty such drugs, but none of them work as well or as long as they should. This may be the best of the bunch, if we're lucky.

    [rant] I'm consistently amazed at the basic lack of understanding of infectious disease displayed any time a subject like this comes up. People seem to have a quasi-magical conception of pathogens roughly equivalent to believing that stars are holes poked in the roof of the sky, through which the Divine Light shines through. [/rant]

    Antiviral medications do exist. None of them are as effective against viruses ([ob] no such word as "viri" [/ob]) as the best antibiotics are against bacteria, but they're out there and getting better. I think that what you're thinking of is vaccines, which do "train" the body to detect and resist infection (viral, bacterial, or other) and can be very effective -- depending on the target. Smallpox and polio, fortunately, turn out to be fairly easy to make vaccines for. HIV, unfortunately, doesn't.

    Um ... we know perfectly well what they do: make copies of themselves. Now, the circumstances under which they make copies of themselves, and close analogues of themselves in RNA, is in most cases still an open question -- but simulations like this are an important step on the road to figuring that out. Of course it's trial and error; that's how science works.

    I believe the system works, despite its flaws, when it is used the way it was designed. In the case of the government, we have a perfectly good design: the Constitution. The problem is that the current government is ignoring that design. The "valid alternative" you're looking for is simple: follow the design (which, BTW, was laid down by people with much more historical knowledge, and in some cases direct personal experience with tyranny, than the vast majority of modern Americans.) Why is this so hard to understand?

    No, they do make the hypospray-type things, or at least they used to; we used them to administer mass immunizations when I was a medic in the Air Force, because you can inject a lot of people a lot faster with them than you can with a needle. You know why they never caught on for general use? Because one thing Star Trek never showed you is how much the damn things hurt. I mean, a hell of a lot worse than a needle. And they leave nasty welts. And if you twitch, even a bit, while the injection is being given, you'll end up with a deep cut -- again, much worse than what you'd get from a needle. No fun at all.

  11. Re:Isn't it time web development moved on? on Web Development with Apache and Perl · · Score: 5, Insightful

    Old-school Perl CGI is relatively slow, yes, though an awful lot of that has to do with the quality of the back-end code. But mod_perl is unbelievably fast -- and I say that as someone who makes his living developing and maintaining a database with a Web interface written in PHP, so it's not like I'm prejudiced in Perl's favor. "Serious webmasters" choose whichever tool gets the job done best, and if they're also good programmers, they write good, clean code that executes fast enough that the client doesn't have to care what's driving the site.

    That being said (anti-flamebait!) I'm amazed you mentioned ASP, not because of of its flamebait value, but because, um, it sucks. I swear to God, there must be "if(client != "IEWin"){slow_down(); crash_unpredictably();}" in the source somewhere. Even these days, old-school Perl CGI is often the right tool for the job. Unless you're developing 100% for IEWin, IIS, and MS-SQL, ASP never is.

  15. Re:Slavery is bad, mmkay? on How The Postman Almost Owned E-Mail · · Score: 2

    Yawn. The states that seceded did so because they thought (rightly or wrongly) that Lincoln would be an abolitionist President. The purpose of the fighting for the North may have been to preserve the Union, but the cause of the war was Southern secession over the issue of slavery. Generations of Confederate apologists have managed to introduce some doubt on this issue into people's minds, but a reading of the letters and speeches of the time makes it clear that if not for slavery (and abolitionism, to be sure) the secession, and thus the war, would not have happened.

On the other hand, the sense of everything flowing just right in the ER was something I experienced maybe once or twice a year, because the kind of shifts required to get that feeling didn't happen very often.

I've experienced it while running, while coding, while writing, while having sex (okay, lately I haven't been practicing that last as much as I'd like, though things do show signs of turning around soon ... ;) Hell, I used to sometimes get that same feeling back when I was an ER medic -- a busy night shift in the ER is no one's idea of fun, but there's a definite flow to it, a rhythm, and when you really get into it, when you're triaging mass casualty victims or running a code and everything is going just right, it's a powerful experience.

It's designed to blow up or disable vehicles, artillery emplacements, etc. Might people nearby be blinded by reflections? Sure, and people nearby when a bomb hits might be blinded (or worse) by shrapnel. I think this is much ado about nothing, to tell the truth. Battlefields are dangerous places.
