Sorry, but that fact is not relevant here. See many other postings regarding that in this story. Having a partial pressure of oxygen "equivalent to 10,000 feet" but with a "normal" atmospheric pressure, translates to an oxygen percentage of about 15%. The total atmospheric pressure at 10K ft. is 10.1 psi. Normal air at that altitude is still 21%, so things burn normally as you irrelevantly pointed out. Big whoop. Some people (especially young Navy kids) can function quite well at 10K ft. equivalent for quite a long time. (150 kPa O2 vs 210 kPa O2 partial pressure). Others will suffer the effects in the article you linked to. YMMV. But cigarettes won't stay lit in 15% O2 unless you're dragging really, really hard. Believe me, it works. Not that you would want to go through this experience for long though. Headaches were common, and the tobacco junkies quite unbearable. The A-gangers got the O2 generator working after a few miserable days. Go put yourself on the dink list, skimmer!
A few decades ago I served on a submarine. The oxygen generator stopped working for a while, and for operational reasons we couldn't snorkel for fresh air. The percentage of oxygen dropped below the point where combustion is supported, so the smokers were out of luck. People's lungs respond to the partial pressure of oxygen in air, not the absolute percentage, so the crew including myself were fine, since we were only at about the equivalent of 10,000 feet (US units). I always wondered wouldn't it be safer from a fire prevention standpoint to always operate like that.
The policy regarding original research may understandably seem counter-intuitive in cases such as you cite, but that policy results in a verifiable set of facts. Just as in Science, when an experiment is not repeatable or verifiable, a result (however interesting it may be) belongs in some other category until it can be repeated.
Editorial comments which violate the
Neutral Point of View should be removed, regardless of their apparent truthiness.
I've got over a hundred pages on my watchlist, and although I'll revert blatant vandalism immediately and minor vandalism when I get around to it, if something is just a little questionable, I'll typically leave it alone until I get the time to properly research it. Sometimes that just never happens since I've got a lot more to do than make minor tweaks to Wikipedia pages.
If more Slashdotters would dive in and
help, keeping Wikipedia healthy and useful would be easier.
they were remote copying from one Unix that had 14 (or more, can't remember) char limit on file names
Back in the day, when I was first exposed to Unix in the form of 4.2BSD running
on a VAX/11-750, the limit on file name length was 14 characters. I had been using
Data General AOS, which had a 31 character limit, so I was initially unimpressed.

Meanwhile, the Whitehouse published
this memo last Friday.
It's about time, IMHO.
There has always been a multi-modal distribution of computer literacy, but I've seen a shift of the truely clueless to the Windows platform, and most Linux geeks I know use OS X also. Any OS geek of any stripe understands the need to be vigilant with patches and configuration, but that still leaves a large middle ground of the moderately informed user.
It is these Mac users who will contribute to a future OS X security debacle. When Apple releases a Security Update, the geeks will apply the updates right away, and the clueless will do as told. But the middle ground still has the dangerous attitude that security updates on the Mac aren't important since the OS is so secure already. This is a problem.
The best substitute I've found so far is the Radio Shack Pro 35A. They are 1) Light, 2) Sound OK, 3) Inexpensive ($20). For air travel, the Maxell noise-cancelling headphones available at Walmart for $35 are a good bargain, but don't sound as good as the cheaper Radio Shack headphones. Just say no to earbuds.
nobody's re-buying the old Pink Floyd albums they already own in another format
I don't know how many years it's been since my last copy of "Dark Side of the Moon" was
either liberated by a roommate or just otherwise lost, but I bought that album
from the ITMS just last night, along with some vintage Elvis. Before that, I bought some
Miles Davis, Van Cliburn's Rachmaninoff Preludes, and the Fleetwood Mac Rumours album
for what must be the seventh or eighth time in the past 30 years.
I owned my 30G iPod Photo for about six months, loading my 200 CD's onto it first before
tapping the local public library's collection.
I only recently began buying from the ITMS, and I've probably spent $200 so far, buying
old familiar but long lost albums, along with some new stuff.
My elderly father really likes the Dragnet episodes, which are quite unintentionally funny.
And my daughter loves the Pixar Shorts. You've really got to take a look at the Birds and
the one with the dancing lamb. Those are easily worth the $1.99.
So, if my buying habits are reflected by very many folks, Apple is in no way holding back anything.
Why does Science always have to move forward? What about old discarded theories, such as Phlogiston theory. I propose that any Chemical Engineering course teach about phlogiston along with the "dephlogisticated air" theory, otherwise known as oxygen.
Maybe Astronomy classes should give equal time to the
Ptolemaic system. And what about Tycho Brahe's system? Copernicus Shopernicus, it's just a plot by telescope manufacterers to sell fancy schmancy equitorial mounts and clock drives.
Math classes could spend a little time working on
Squaring the circle
and finding a counter example to the
Four color theorem.
The students could even use crayons or finger paints.
This could all make school so much fun! And the students so stupid. One second thought, maybe those are really bad ideas. They could grow up to be
President of the United States.
We have one oftheir products a few miles down the road from where I work.
From a Panasas press release:
The Panasas storage cluster can scale from Gigabytes to Petabytes in capacity and still be managed as a single system. Key attributes include: a single virtualized global namespace, dynamic load balancing and Quality of Service attributes. These combine to simplify ongoing operation of the system while maintaining peak effectiveness.
I was (and still am) a Linux zealot for 13 years. I've been an Apple zealot for two years now. You can get your start with the Mac mini, 'though I'd wait for Wednesday's "Red Velvet Curtain" announcement in case something really interesting is in the wings for Macs. At least wait until the Mac mini upgrades are official and included with every order.
If you feel comfortable with a pair of putty knives, that approach would certainly be the smarter way to go.
Looking at Activity Monitor, I see that the Wired+Active memory is frequently above 512MB, so I'm glad I opted for 1GB. Had I been a little more adventurous, I could have saved about $125 (not counting the putty knife price).
The main problem with these new systems is that it doesn't appear easy to order a system without Bluetooth or Airport. Where I work, both of those are not allowed (for security reasons), so those little antennae will have to be removed.
I got a maxed-out Mac mini about two months ago with 1GB RAM, Superdrive, Bluetooth and Airport. That package cost $1,023. The very same configuration today is $874. That's quite a nice improvement. Do I regret not waiting? Maybe a little, but that's the way things have always been with computers. For anyone considering a Mac mini, I'd recommend going for the 1GB option now rather than later.
Switching between Qwerty and one of the more common Cyrillic keyboard layouts is also not a problem, even when only one key "c" is in the same position, "a" and "f" are reversed, and the rest are totally scrambled. Although I've never used Dvorak, I suspect that it shouldn't be very much different than switching languages with different alphabets, which is quite easy for me. Others may have a different experience. I remember a co-worker who had problems switching between keyboards where the caps lock key and the control key were reversed, so as usual, YMMV.
When Rush Limbaugh is available via podcasting, it's mainstream. Regardless of your opinion of Rush, he's
staying up with technology.
I just updated to iTunes 4.9, so I guess it's time to run out and get my first iPod. So many choices, but it looks like the $299 new color iPod will be the one I'll get.
Of course, I knew what the writer really meant.
But the Bable Fish translation into French produces
exactly the meaning which I first parsed when reading that headline.

If machine translation become more common, perhaps English writers will have to be a little more careful.
Make the entire wall a whiteboard.
Here is the first thing I found on Google. I'm sure there are more. When I visited Emerson Process Controls recently, they used something like this in their training center. The instructor could draw anywhere, as long as it was on the correct wall.
Wow, that's a lot of code for a project that started out with:
Do you pine for the nice days of minix-1.1, when men were men and wrote
their own device drivers? Are you without a nice project and just dying
to cut your teeth on a OS you can try to modify for your needs? Are you
finding it frustrating when everything works on minix? No more all-
nighters to get a nifty program working? Then this post might be just
for you:-)
Ethanol will also freeze when cooled sufficiently (i.e., -114 C). Just don't try to eat it. Did you have a point? Thick syrup gets even thicker when cooled, and thinner when heated.
I think the point was that substances can behave in unexpected ways. Water does not appreciably change its viscosity when cooled to near its freezing point, yet ethanol does thicken before it freezes.
A really neat experiment is to melt some chunks of solid sulfur and slowly raise the temperature of the melt. It starts out as a slightly viscous straw-colored liquid when the sulfur molecules are little donuts of S8. Then, as the temperature rises, the donuts break apart and reattach to each other, making long strands which become entangled, and the liquid darkens and thickens.
What does this have to do with Ethanol splashes? Not much, but it's interesting nonetheless.

Just pick how many digits/letters you want from either the beginning or the end, and pick a passphrase which you can correctly and exactly remember.

This is just a simple SVO sentence. So, which plans of Lockeed Martin unmanned which aircraft, and how? Inquiring minds want to know.
