Yeah, it's worse than that -- many of the structural elements are made of steel, smelted, cast, and machined using processes that go back even further than Diesel.
OMG y dont we kill these jiants insted of stand on there sholdiers!
If you think that's bad, the guys using the LHC are Homo Sapiens. That's like 200000 years old, it should be run by iPhones, or something...
The latest version of Linux offers a whole host of new features – for example a USB 3.0 infrastructure, drivers for the Sound Blaster X-Fi, KMS support for Radeon chips and improved versions of Btrfs and Ext4. As is traditional with new Linux versions in the main development branch, however, this is only the tip of the iceberg.
Whenever we go to select a laptop for flying, we have a certification process to determine the best ones. We'll test it for how well it withstands radiation. [The ISS is exposed to as much radiation in a day as computers down on Earth are in a year.] We also test for off-gassing, in case the computer emits chemicals that could create fumes on the Station. You'd be surprised at how many computers would survive on the ISS. I can't think of an occurrence when we've have a computer fail from the radiation itself. It may reduce the lifetime of how long we can keep the equipment in orbit, but most of the time the failures are just like the ones here on the ground -- we'll have a hard-drive failure or we'll have an application problem and end up reloading the machine
Mach 1 at the throat is calculated as sqrt(gamma*R*T) where T is in kelvin if R=287. Gamma will most likely be 1.4 and is pretty constant for ideal gases. T can vary greatly, but 3000K is around the right order of magnitude.
Uh? R=287 is true for air, with 29 g/mol, with pure water, it's 462, and more for the mixture of water and hydrogen that comes out of the nozzle.
It's Mach 1 in the exhaust. But even if the flow won't go at more than Mach 1, the speed of sound is proportionnal to the square root of the temperature, so even if the Mach number is fixed at the throat, you can have a faster flow if you can get a hotter gas.
Of course the problem is that with any rocket engine, the gas are already hot enough to melt the nozzle: I've worked on Vulcain 2 and the nozzle is cooled with liquid hydrogen at 20K... I guess other rocket engines use similar solutions.
It can run a root shell, but the manufacturer and carrier, together, can't add items to the interface? What, is the firmware burned into ROM or something? Obviously I'm missing something here, since I thought Maemo was quite customizable.
For carriers, customizing means "shoving our shit down the customer's throat", and Nokia plans to give full control of the N900 to the customer, not the carrier.
on our side of the pond we have cities with more cell towers than your entire country and we want coverage in every little corner in the US even if no one lives for miles around
Maybe my geography or astronomy are off - Feel free to correct/bitch-slap me if I'm confused.
How does a satellite in geosynchronous orbit get 24-hours/day of sunlight?
/bitch-slap
The equator and the ecliptic are not on the same plane, which means the only times when a geosynchronous satellite is in eclipse is around the equinoxes. In the worst case it can last up to 80 minutes of shadow.
The whole point of meters was to encourage people to be quick and move on, freeing up parking so others can patronize the same businesses. That's why there are time limits and feeding the meter is illegal in many places, even if you own the car.
Perhaps instead it's time to rethink the whole concept of meters and find a better way to accomplish the task.
It already exists, it's called a zone bleue:
it's a free parking but limited to 1h30.
You do realize it is "FICTION". Fiction is not necessarily suppose to be scientific. The purpose of Sci-Fi in my opinion is to deal with issues of the day in a format where people won't necessarily reject it out right. Many issues are dealt with and warnings are issued. Lucas screwed up the Star Wars universe with the newest trilogy in my opinion to warn against blind trust in Government, the pitfall of hubris and other things that were pertinent at the time and ring true throughout time. I don't appreciate the poor screenplay or crapping writing, but I understand what he was trying to say.
I won't even bother to do anything more than copy-paste this:
This silly opinion implies that the word "fiction" nullifies the word "science." Since it is "fiction", and fiction is by definition "not true", then we can make "not true" any and all science that gets in the way, right?
Hogwash. By the same logic, the term "detective fiction" gives the author license to totally ignore standard procedures and techniques used by detectives, the term "military fiction" allows the author to totally ignore military tactics and strategy, and the term "historical fiction" allows the author to totally ignore the relevant history.
Imagine a historical fiction novel where Napoleon at Waterloo defeated the knights of the Round Table by using the Enola Gay to drop an atom bomb. It's OK because it is "fiction", right?
This non-argument is the favorite of science fiction fans who like all the zipping spaceships and ray guns but who actually know practically nothing about real science. And who cannot be bothered to go learn.
They more than likely have used it on some special demo machine with the specs and thorough setup to make it usable. Just like Mojave, when users try it in a custom environment designed to make them like it, they'll like it. But that's not what they're getting on their Compaq POS-9000.
Yeah, it's not like the beta and the RC1 have been publicly available for months now...
I've always described this effect with the axiom, "People who feel the need to call themselves experts rarely are. The same can be said for those who call themselves professionals." I'm glad somebody finally got around to studying this effect and giving it a name.

When making accusations that can damage the relations of the two largest economies in the World, we should be damn sure of what we are doing.
And how exactly would accusing China damage the relation between the EU and the US?
The speed of sound decreases as the air gets thinner^Wcolder too.
Fixed that for you.
Actually, he typed *******, but it shows as hunter2 on your side.

Spain's president? seriously?

...That I read the title as "Vulcan Debates Possibility of Alien Life?"
It says you should go back to elementary school?
"The delay in sending or receiving data from Mars takes between three-and-a-half to 20 minutes at the speed of light. "
How are they coming up with that? I thought it was closer to 90 minutes...
I may be wrong, but I think they divided the minimum and the maximum distance between the Earth and Mars by the speed of light...
Well it is the year 5770 in Israel.
And still no flying cars...

I'd like to know the relative orientations of the galactic and solar system ecliptics.
About 60 degrees.

Tell me, which city has over 70000 cell towers?
...24 hours of sun...

Actually the mix of lube and shit is named after the senator...
Instead of making shit up, you can probably help this guy. And before you start bullshitting again, yes, you have a root access.
 Wireless. Bigger than an iPhone. Lame. Â
Yeah, a wired mobile phone is so much more practical...

So has Theo, but things do seem to find a way of getting done.
Perhaps Alan can come over to the FreeBSD camp where we are a bit more friendly. He's a good guy and will compliment any project he latches onto.
Well that's not exactly hard:
