I'm no scientist, but I am aware that liquid oxygen or LOX as it's reffered tho happens to be compressed oxygen (approx. 4000 times the amount that in the air), and this will dramatically increase the speed that a shuttle will be incinerated during a disaster, as the LOX will feed the explosions.
The current shuttle uses liquid oxygen, by the way, along with(surprise) liquid hydrogen. Together they fuel the orbiter's engines. The boosters on the side are solid-fuel motors and once they're lit, they don't go out until the fuel's burned.
Incidentally, every rocket fuel of one kind or another has to have some oxidizer, or it won't work in space(think that one through.) Most rockets for non-space applications have oxidizers, too, because it's hard to get oxygen from the air mixed in with fuel fast/well enough to be useful(this is why ramjets were so 'neat', they don't need to carry oxidizer, but can generate enormous amounts of thrust at incredible speeds.)
The orbiter also uses hydrazine for the auxiliary power units and firing thrusters(I think), and a half dozen other things that go 'boom' or are very nasty. That's the whole point behind rocket fuel- burning it has to release a LOT of energy for its weight.
I think Taco is trying to tell us something, but for the love of me I don't know what it is.

Seriously though, this is pretty lame after about repost #3- we get the idea. What would have been MUCH funnier would have been an announcement that Jon Katz was back on staff as an editor, adding his own two dollars to every story before it was posted.

I distinctly remember my professor say that there is a tarrif on lcd screens for the US market.
It was established in 1991, removed in 1993...and it applied only to components, not finished products, if I read it correctly:

Where are all the high-res LCDs from laptops?

LCD Price Fixing?

Here's another question- why don't we see any of the laptop screens in desktop versions? Among other things, it would make the screens cheaper for both uses.
For example, I'd love a 15"(which is equal to my 17" CRT) which supported 1280x1024. My CRT does that easily- but to get 1280x1024 in an LCD monitor, I have to slap down some serious cash and get a much larger 17"(equal to a 19" CRT- and 19" cRTs can easily do 1600x1200.) I mean, hell, you can easily get laptops with 15" 1600x1200 screens. They've been around For at least a year.
Why is it that the ONLY thing you can get standalone is a 15" 1024x768, or a 17" 1280x1024?
Whoops, sorry- it's a technicolor spinning disk cursor that served as MacOS X's "I'm busy" indicator. It got its nickname because in early versions of OS X(ie, 10.0), it would appear ALL the time; subsequent versions improved matters dramatically.
Sometimes it was only one application that would show it(ie, you could switch to another app and keep using the other app), other times you'd get it in all applications.
A friend, who did a lot of OS X development and attended WWDC and such, said that the cursor indicates when the application has stopped responding to events.
I've been running the 2.5 kernel on my laptop for a couple of weeks now to get the new cpufreq support.
This reminds me- one problem I've always had is that new stuff that gets thrown into the kernel isn't clearly explained- in the most basic ways. Ie, what the heck is it? I remember lots of versions of 2.4 had features and options with no help to explain what they did. Google searches don't always turn up anything handy- often they turn up lots of hits on patches or posts talking about the feature, but not describing what it actually is.
Anyway, For those wondering what the heck cpufreq is...From a kerneltrap interview:
JA: You also mentioned working on the x86 side of Russell King's cpufreq code. We spoke with Russell King in an earlier interview, but we didn't talk about cpufreq. What is it?
Dave Jones: Quite a few CPUs these days allow changing of the voltage/multiplier/bus speed through software. Russell and Erik Mouw did a bunch of work on the ARM CPUs that support this feature, and started writing a generic framework for this type of technology so that he wouldn't have to duplicate code that for eg, recalculates loops_per_sec in every speed scaling.
most of the original Macintosh's ROM was taken up by a COLOR image of the Macintosh development team.
Technical correction on this one- I can't find any 'google evidence' to collaborate the above, so I might be wrong, it might have been black and white, and I've probably got the wrong Original Mac model(there were a number of them- the Plus, the 128k, 512k, 1MB...then there's the SE, SE/30...yadda yadda.) Oh well. Sorry folks.
I am positive about the 660AV having the beach party picture- there was a program you could download that would extract it from the ROM, and I gave it a try- amused me greatly:-)
I remember the happy mac startup icon from 1984... when the Mac was happy, *I* was happy. When the Mac had a twisted mouth and Xs for eyes, I wasn't.
Some folks may remember the happy mac actually winked at you during startup in one of the OS 8 versions. It was quickly yanked- Apple supposedly got a backlash(or feared one) from cultures/countries where winking is offensive; search on google and you'll find a ton of links about it.
Similarly, they yanked at one point the Chimes Of Death(doo wee do doooooo) that accompanied the dead-mac(and error code dump), usually caused by severe hardware or software problems during booting in older macs. It genuinely freaked people out(I know it scared the shit out of me the first time i heard it.)
Random trivia- most of the original Macintosh's ROM was taken up by a COLOR image of the Macintosh development team. My 660AV's ROM contained an image of the team(much larger) at a beachparty. It is so sad to see that easter eggs have pretty much been killed off for years now in apple hardware/software.
Curious- Did she design the Spinning Pizza of Death, in OS x?
Obligitory slashdotting joke: Her site could use the SPOD right about now:-)
Get some perspective, man, there are far more dangerous things to worry about than falling VW- sized rocks.
Likewise, we're flushing billions down the drain just on domestic security, all because twelve guys crashed a plane into a bunch of buildings and killed about 3,000 people(total, across all the scenes.)
Wanna guess how many people die, every year :
On our highways? 42,000
From smoking? 170,000+
From heart disease? 710,000
Yessir, we've really got our priorities in order. Let me put it this way- is your town's fire department buying defibrilators, or chemical suits? is the government buying advertising for telling people how to eat better, or warning them to "be prepared" with duct tape and plastic sheeting?
Not even willing to put up a fight, unwilling to take a stance.
Actually, they're taking a VERY clear stance- the war is wrong. Europeans have repeatedly made it clear that they don't really hate Americans, they hate the Bush administration..
Meanwhile, Americans are too stupid to figure out the subtle distinctions between, say:
-supporting "the troops" versus being against the war.
-national security policy of preemption, versus "its about the oil!"
-a dictator who MIGHT have some weapons of mass destruction, versus a legitimate threat to US national security

When it runs low on pressure, do you have to pump the little plunger a zillion times until you're back to full-blast?
