I forgot to mention one of the most imporant effects: matter which is around a black hole tends to form accretion disks. It forms disks because it tends to have a net angular momentum about the black hole's center, and so spins. The fact that differing parts of the accretion disk move at different speeds means that there is a lot of rubbing going on -- not unlike with slashdot readers. This leads to heating of the accretion disk, often up to a very high temperature; the accretion disk is just like a very hot oven, which doesn't emit (much) in the visible region, but a lot in the x-ray region of the spectrum. There are also tremendous focusing effects of magnetic field lines (accelerating charges again), and so the emitted radiation tends to get focused along opposing "jets".
Light and x-rays are the same things (as you imply), just at differing frequencies. Visible light can escape from outside black holes' event horizons, just as easily as x-rays.
Any electrical charge undergoing an acceleration emits radiation, if it can couple to its environment. Charges which are accelerated more emit radiation at higher frequencies, and accelerations near a black hole's event horizon are very large, so x-rays are emitted preferentially over visible light. There is also an effect of higher frequency emissions from any finitely-sized source being more "focused" than lower frequencies. This leads to more concentrated "beams" of emission from finite sources.
Finally, one of the methods of radiation from black holes is that of spontaneous particle-antiparticle production in the tremendous gravitational gradient outside a black hole. Normally, these particle-antiparticle pairs recombine quickly. However, if one travels nearer a black hole than the other (they're emitted going in opposite directions relative to their center of mass, to combine linear momentum), it can get sucked down the gravity well, and the other escapes.
.... but I keep reading about how movie directors are bringing in real experts (history experts, etc., on movies like The Patriot, and science experts on all sorts of movies) to advise and make sure that mistakes aren't made (within the realm of artistic license). Then, when I see the movies, I notice all sorts of glaring errors are made (I only notice the sciency -- and a few computery -- errors. Dont' get me started on Spiderman2 or Chain Reaction). If they're going to bring in these experts, why not listen to them? Really, "whoosh" in space?
I agree with you completely. Having a father who taught graduate-level English made me extremely sensitive to transgressions. On the other hand, people are people (some, indeed, aren't native English speakers/writers, so may be forgiven for never really having learned the adverb/adjective rules), and I appreciate that the whole point of the language is to communicate.
Of course, everyone understands this at some level. I'm preaching to the choir. Just wanted to say that your pet peeve is one of mine, too, and it *should* be one of anyone who attempts to use English. Too bad there's only so much time in one's life.
In most cases, such vulnerability will be showcased as the one that would cause death and distruction of all linux deployed systems, when most vulnerabilities in windows shall be deemed fit to be ignored, under all circumstances, not to mention, for all the quoted linux vulnerabilities, windows will mostly not have a similar lines vulnerability, and if at all they exist, the official word would be that they had fixed the vulnerability before they started developing windows platform.
Not to mention the particular mindset of open-source users, who try to conserve periods and capital letters following each period and a space, thus leading to single sentences with positively Hemingwayesque qualities, oh! the horrors! when probably several sentences (or even chapters) could do the job more simply.
What makes his stories so successful?...The best blogs, we found, are not those that actually get the most page views in a day, or that get the most links. In fact, the blogs that get the most links are the ones who find the best blogs and then point the best blogs out to the rest of the world.
Thank you. That was very neat. I'd like to think that me and mine are smarter than to fall into such a hysteria, but humans do strange things. I'm going to send that link to my friends.

The new wafer plant will be built in an existing facility at Chandler, Arizona, and will feature 45nm technology - 1/1,333th the width of a human hair.
Yay for science writers using numbers in dumb ways. So glad that all humans have all the same hair thicknesses, and they're all about 59.99 microns. According to various sources (and I've measured hair diameters myself), they range from 200microns down to about 50 microns. So the article should have stated that the 45 nm technology is somewhere between 9/10000th and 9/40000th the width of a human hair. Wouldn't that be much more impressive?/sarcasm
Seriously, what's to prevent the eviil geniuses from nuying the printer a long ways away from where they actually use it and waiting a while before using the printer?
Ah-hah! You gave yourself away. You're from Van Nuys, aren't you? Better luck next time!

Very nice explanation. You've read up on your ancestry?

of course
I hate the Deaf and Disabled telecomunications program for not listening to complaints.
*cough* Of course they're not going to listen to the complaints...
... they're better than the Clappers we used when I went to school.
Now, if we got to use the crapper, that'd be OK.

"Works pretty well" damnit! Why can't anyone ever get this correct?!?!
:)
The OED has no such word as "damnit". In addition, don't you need a comma before "damnit"?
You're right -- I didn't follow any of them quite far enough to see that, eventually, the links' addresses do show. Thanks.
/bitchiness
Their summaries (beginning of the story) aren't nearly long enough to find out if those are links I want to follow, in general.
I don't like the fact that links' targets don't show when the cursor goes over them. I never quite trust sites/links that do that.

But good comments are not always necessary, sometimes subpar will do. Next question.
Wait -- we're supposed to be talking about code, not Slashdot.

Uh.... Huh?
Asking again.
Outlook hazy.

Doubtful. Ask again later.
They also don't have a dropdown menu on the back button
The dropdown menu for the forward button works for both.
They could've just put the functionality into the "Start" button...

Yeah, Epsons can be cheap, but that's not nearly going to cover ink.
Did a project in college to detect and characterize some of these "noises", but in the Earth's atmosphere. They're really very interesting.
