This thing is definitely cool. The other posters were right in pointing out that it regains the energy via converting solar energy into momentum by applying a current to the Earth's Magnetic field. I just wanted to point out the purpose of the devices name:
Momentum-eXchange: this refers to how the tether adds momentum to the spacecraft
Electrodynamic Reboost: this refers to the mechanism that recharges the orbit
The one poster is right about the momentum-exchange working both ways in that spacecraft coming back could tether down and reboost the device. However, in most cases the craft will be leaving a payload up there (such as a satillite, or even just burned fuel/oxygen) so it would never regain as much momentum as it lost. The electrodynamic reboost ensure it keeps flying.
It's not so much the location of the power supply that changed as the location of the chip and the length of the motherboard. On ATXs the chip is required to be right under the power suppy, so that the fans int he power supply are used as part of the cooling. If you put an ATX in a small AT case, this means the chip will be right where the AT power supply is (I only know this because I mistakenly tried to put an ATX mb into my small AT case).
On a full tower, the AT power supply should be well out of the way.
The connections at the back wouldn't have anywhere to go since ATX cases have a rectangular bland are that allows the motherboard manufactuers to put whatever they want. By contrast AT cases have a specific place for the keyboard and then cutouts for serial and parallel ports (which are on ribbons, so you can reposition them). So I'm guessing you cut up the back of your case (or found an AT mb for a P3 which I didn't realize existed), which is also not something many people would do, especially since it can kill airflow if you do it incorrectly.
I haven't seen the video in question, but if it wasn't a full tower like yours, then the power supply would have had to be relocated, since the chip would be where the power supply on an AT is supposed to be.
techniaclly, tar | gzip does this, because gzip only sees one file: the tar archive that has all the files.
However, I'm not sure if it uses a dictionary for the whole thing (requiring the tar file to be loaded into memory so that it can do a 2-pass, one to build the dictionary, one to compress), or if it modifies the dictionary as the stream goes by.
Or maybe the market for games is this demographic because of the games that are offered. For example, "the Sims" appealed to a wider demographic (notably females) and is the number one selling PC game of all time.
You say this like XP doesn't have a BSOD. But I've had it happen to me (repeatedly). It doesn't look like the old BSOD (a darker blue and smaller left-aligned text), but it's still blue and it still occurs when the system dies.
In this day and age how many people don't know what a harddrive is who need to use the "My Computer" icon on windows? I'm hard pressed to think of an example.
C'mon. You've never heard people say "I only have 3G of memory left, and that's why my computer it running so slow." Practically everyone I know who can't put a computer together will say this.
Yeah, but a rifle is nothing compared to a 120mm, attached to an Abrams tank or not.
There are many guns that you do need permits for, at least in most states (There could be states that don't require one). Now you are right in that most rifle's you don't have to have a permit for, but this limits you even more in your selection of weapons. And you still need to go through a background check.
As for the "You commit a felony, and get sentenced, you don't get a gun" philosophy, this is exactly why voting and gun ownership are priveledges. I've never heard of a right that can be taken away. The way we work now, a felony law can be put up for some common behaviour of a specific group, and then enforced strongly on that group to take these "rights" away. Now I understand if you prefer it that way, but don't insult the ideal of freedom by claiming we have it.
>No, you don't necessarily have a "right to a gun"
Oh, I don't? Sorry, pal, in my country I do.
You must not live in the States. The way it works here is that you have priveledge of being able to own from a short list of weapons, all much weaker than military hardware and completely unable to provide the security of a free state if an enemy or civil government were to attack us, and this priveledge can be taked away in many cases from incorrectly filing for your permit or being convicted of a felony. The latter allows the government to enact laws that target a certain demographic, such as criminal processing for smoking or ingesting indigenous horiculture, and thus reduce the amount of people in that demographic who can own a firearm (the same process is used to take away the priveledge to vote).
Radians are poor in computer calculations because they cannot be accurately represented (since pretty much any normal division is an irrational number). Instead, you get truncated numbers that are near the real answer. After enough operations, your calculations are wildly out.

essentially, it's a momentum capacitor.

Well, maybe you should just ignore him.

Quite an impressive accomplishment... it took them 25 years to reach the billions, but they estimate that they will hit 2 billion by only 2007
I guess every 25 years, the consumption of microprocessors quintuples.
But there are also PCS systems, which are low power mobile phones that need to be near a basestation. They are common in cities.
5) ...
6) Profit!
Psst.

I downloaded a copy of Ghost Dad and it was pretty similar. It wasn't dubbed, and didn't have subtitles, it just really sucked.
"and that's why my computer is so slow"
they don't really know

Canada isn't much better.
It's called Irritable Male Syndome and is coloquially called Male PMS (google gives more results for the latter).
It doesn't even matter if they are on target, because buildings ted to catch fire when bombed, and fire tends to spread to other buidlings.
Doesn't anyone use sed anymore?
