Even more: if you don't optimize the code specifically for the GPU-based supercomputer, your performance goes down the drain. I wouldn't be surprised if they obtained a speedup of an order of magnitude or more from the aggressive code optimisation.
The idea is: the original code would run faster on a 8 Core2Duo machine than on the 8 GPUs. Even more optimising of the code will do little for the Core2Duos, due to limited memory bandwidth, FSB bandwidth, and so on.
Meanwhile, optimising a pipelining sistem (load, compute, store) in the GPU would be greatly improved by huge bandwidth (50GB/s on current systems), huge number of computation units (128 or more) and so on.
Because floating point operation goes on a dedicated path, while the integer operations does not have a dedicated integer-only path. Also, it's possible that loading floating points operands and storing results in actual code can be pipelined, while integer operations are not pipelined.

Rail transport was big in my country in the past - the big manufacturing companies had rail tracks inside their yards.
However, lacking this, railway transport means road transport to the train station, load transfer to boxcars, railway transport (which might take a while, as passenger trains have priority over cargo), then load transfer to trucks at the destination, and finally transport to destination.
As long as your transport can take a long way on the road, and you can send a train or at least several boxcars, using trains is a good idea. On long distances, trains might get faster than trucks (trains can go all day long, changing engineers, but truck drivers must sleep).
Officially, encrypted data on the hard drive is lost if the password is forcefully changed (by any means other than , Change Password or a dialog where the old password is introduced too).
Resetting a password (when you have a working administrator account) is as simple as going to Control Panel, Users, Advanced, and "Change password" (or use the User Management in Computer Management)
Your Dell comes with a 15.4" display, better resolution, better processor, more memory, bigger non-volatile storage, a normal keyboard, and maybe other things.
And weigh three times as much as the EeePC. There is a market for lower performance, light computers.
The EeePC is equipped with storage similar with what was mainstream some 10 years ago, with a processor (600MHz) from 7 years ago, and its 512MB RAM is pretty current (not more than two years ago in the mainstream). Its graphic resolution, unfortunately, is from more than 10 years ago, and is a quarter (by pixels) of what is now current.
With a bigger display (600 lines instead of 480, and more than 7") I would buy one. For comparation, most of the installation screens in Windows I've seen doesn't fit in 640 lines, the OK, Next, Back, Cancel buttons are out of the visible screen.
"The DivX/XviD version comes to about 95mb. The exact same thing encoded in h.264 at the exact same quality (720x480) clocks in at about 45mb"
You should mention the other side of the equation:
The processing power needed for the h.264 file (encoding, decoding or both) is vastly larger than for the DivX/XviD version (I don't know if the H.264 codec is optimised for decoding - it could be, usually making encoding a much more time intensive operation).

The only chance for radar detection would come from an overhead radar - the visible horizon for something as low in the water (the area where it could be detected too) is no larger than a few miles.
And surveillance, airborne radar probably are much better than the big ship mounted counterparts - yet, they might not suffice.
Sonar signature? Check, as close to nothing as possible (you might still have transients if the moving equipment starts to squeak). Radar signature? If you make it entirely from plastics (or at least the hull), you could get that Heat signature? The surface of the boat will heat/cool faster than the surrounding water. But if you put a generator on it, there will probably be a heat signature.

Flamebait, but I'll bite.
First, the US Department of Justice decided Microsoft was a monopoly, so the European Union could very well take this for granted (the supervision for Microsoft as an monopoly is still active, with a recent two years added span).
Second, while the EU might fund Airbus, Boeing is an equal competitor to Airbus (at about equal size). Microsoft doesn't have competition of similar size - not even in a tenth of their size.
If an european citizen would be fined for parking in New York, those money would go toward reducing the taxes paid by the US citizens, increasing their capacity to compete against the Europeans.
I think the americans lost the stomach for competing against Microsoft in its main area of expertise: Novell Netware is just a shadow of its former past (and Windows networks dethroned it), I haven't heard lately news about Word Perfect (once leader of the word processing world), Netscape (once leader of web browser world), let's not even talk about Winsock Trumpet. I even remember a Corel Linux (rumours say Microsoft paid them out of the idea).
Microsoft's idea of "laissez faire" competition is to be alone in the world, and had taken steps for this (why buy now OS/2 when you can wait one year for our new Windows Chicago). For better or worse, OS/2 - once a competitor of Windows - is out of the marketplace for good.

You can use a GPL licensed product in any way you wish.
GPL imposes limits on you only if you distribute GPL code (or the result of its compilation)

Hopefully there will be competition and it will decrease the prices to an even lower level. At least I can hope

How about your house be for auction every 10 years or so, and if someone outbids you, he will pay you the money he bid and see you on your way?
