If that is true, it's not even worth mentioning in a high-speed train discussion (I was under the impression it was a smidgen better than 210). Even the old Corail trainsets (180 km/h initially), once refurbished in the new Teoz service, reach a commercial speed of 200-210. And these are really plain jane classic passenger trains.
Actually, this bent track was more in the sixties, the '70s tests were around 250-280 km/h in a very straight corridor (Mulhouse-Strasbourg), and didn't actually destroy the tracks (with the amount of traffic on that line, they'd better not to:-P) More modern pendular systems such as the ones build by the Swedish, the Italians or the Canadians, achieve 230-250 in commercial speed on reasonably modern classic tracks.
Another challenge the TGV (and ICE) solved is the power supply: conventional electric feeding systems vibrate too much at 300 km/h, and even if you managed to reach that speed despite the poor contact, you'd rip the cables away. (in fact, the TGV 001 prototype, still displayed on the A35/A36 motorway near Belfort (place of construction) and Brumath (large maintenance facility), as well as its commercial predecessor, the Turbotrain (still in little use on Paris-Normandy and a few even more remote regional lines), used a gas turbine specificially to avoid this problem.
X-2000 or Pendolino would probably make a lot of sense given what I perceive should be the state of China's tracks and maintenance procedures.
Well, EUR45 is well within the price range of economy Swiss watchmaker Swatch, which is affordable by almost everyone (if you currency tanks, hold your authorities accountable for it, not us).
Then, there's plenty of quite fine domestic coffee here (OK, the raw materials come from the Americas, but you see what I mean), and finally I'm a fat penniless bastard, and I can still find cheap ski resorts with this system enabled, to which I can lug my Toyota at 130km/h not 130.1 otherwise the Prunomatic radars are going to mail me invoices I can't afford to pay.
I find this "wheee! neeew!" attitude amusing, but sometimes (not all the time, far from it), stuff which is news for the USA is soooo boring old in Europe and/or in Japan (quite more frequently the latter, actually)

Now let's lie a little bit with those numbers:
EU-15 + USA = 665M people (yeah, perhaps not the purchasing power of 665M of 'merkins, but rising faster than we here might want it to).
Strictly on basis of population (I'm going to ignore my future fellow citizens for a minute):
not even talking about purchasing parity (initially at the advantage of the USA, but now the USD is taking a dive, while the rest of the alleged west is pretty much moving along (well, the AUD is climbing even faster against the USD, if that even mattered. The only thing that matters is that the Chinese are cheating with their monkey currency).
(don't forget that when economists are talking about "western countries", some are actually including Japan, 127M of deep pockets)
I'm afraid I'm not the right guy to ask for fancy 3D graphics under Linux:
muscat%lspci | grep ATI

(in my other life (payin'bills Win32), I am doing some OpenGL stuff, but nothing which qualifies as "fancy", and most hardware available nowadays is more than adequate. Sorry!
That said, I'd stay away from any solution with binary-only drivers on Linux. Just out of principle (and, that was #1 factor in choosing the Rad7500 over similarly-priced Nvidias).
Well, guess why Kissinger doesn't want to even risk going to Canada, let alone Europe.
Several countries would love to try him (he probably has good defence devices, and he absolutely, just as you, me, and your typical Guantanamo guest, is entitled to a competent defence, but he certainly has some explanation to do over his carreer. And he gets angry real real fast (I witnessed that during a live interview) when someone just begins to hint at Cambodia or Indonesia).
If you don't think that the single example of Indonesia (by the way, the Australians aren't nice just out of philantropy), how about South America? September 11th <b>1973</b> and the like? Operation Condor? etc. ad nauseam.
Yes, France sells weapons to the bad guys occasionally (heh, ask the brits anytime). So does everybody. And the USA's not clean either. Every dirty trick in the book, every first-world nation practiced, or practices, or both, and needs very careful attention from its citizenship (where it is still "free and/or brave") to not practice again.
If you think the USA are the good guys unequivocally, I have bad news for you: a lot of people disagree, and sometimes they have decent grounds for that (and afterwards, dissent is a normal and healthy thing where Freedom exists, isn't it?).
East Timor was invaded (with mass murders and all the tralala until the Aussies went to clean up the mess recently) with Kissinger's blessing, with US-build weapons (theoretically sold for defence purposes only, but I don't see the point of H.K.'s visit a few days before the invasion started).
Here's the problem: you aren't sure that this sat will be efficient enough during these 15 years to deliver these 2GW. Perhaps 2GW at the beginning, but 0.5GW at the end (and I'm perhaps stretching the current state of technology).
Now this brings a dent in the economics of the project, doesn't it?
OTOH, you can probably count on economies of scale: if that thing works, there will probably be a couple dozens of these birds up there.
I guess that if AXA is looking at a specific 98 Dodge on an Irish Motorway, it shouldn't have too frequent false positives if it can identify the car body and trim...

where the Fine Manual = The Athlon 64 and Opteron optimization guide (PDF from AMD).
It's spelt out in full, page 225:
Future processors with more or wider multipliers and adders will achieve better throughput using SSE and SSE2 instructions (Today's processors implement a 128-bit wide SSE or SSE2 operation as two 64-bit operations that are internally pipelined).
(...)
The SIMD instructions provide a theoretical single-precision peak throughput of two additions and two multiplications per clock cycle, whereas x87 instructions can only sustain one addition and one multiplication per clock cycle.
The SSE2 and x87 double-precision peak throughput is the same, but SSE2 instructions provide better code density
(emphasis mine)
So, in other words:
SSE is twice as fast as single-precision x87
their initial implementation of SSE2 is actually just an implementation of the instruction set, the actual execution units are borrowed from the x87 and have the same throughput limitations
if you are writing really large code, you might get some benefits from SSE2 because of L1 savings (but your case has to be pretty borderline for that to make a significant difference, or you have to be able to interleave a significant amount of integer code with your FP code that using SSE2 frees enough decoder bandwith).
In the future, they might bother with spending more space for more double-precision FP units (I'd think that if they can sort out the manufacturing problems, and the HPC segment seems like the area they're selling to, then it may make sense to spend a few mm to double SSE2 performance. Depends on who actually buys Opterons once the software/OS front lines are settled)
Today's AMD64 SSE2 performance in double-precision is not going to be leaps away from their x87 stuff (unlike the P4), but you have to remember that AMD's x87 is really good.
Don't forget that in long mode, you have 16 128-bit registers, which may help your compiler make more out of SSE2/64 code than x87 code; some benchmarks with SSE/SSE2 enabled compilers would help clarifiy whether that's the case or not.
So in short, yeah, they claim a somewhat faster SSE, but their SSE2 is mostly a "yep we can run that code too" item rather than "yep, we can run that code too, and faster to boot".
No it doesn't. I'm using it with PPPoE, because I use one of the first-batch ECI HiFocus "Merkava" Ethernet bridges, and the firmware I'm stuck with won't do anything else than PPPoE with the kind of DSLAM the still-monopolistic local-loop provider is providing.
Many folks are using the alternatives, but till my modem breaks, I won't bother to fix it, especially since I don't see what I would gain from switching from PPPoE.
My ISP provides me ipv6 natively. Yep, a full/48 for me. And it's on a plain vanilla home DSL line.

Even assuming that the blob of concrete comes out undamaged of its encounter with the target, it's not that clear that the same will happen to the guidance package. Though I don't think the concrete they use is of the garden variety, I'd think that it's cost is peanuts compared to the guidance 'tronics.
Besides, you don't always want to go fetch a 500kg blob of concrete after you dropped it on hostiles, do you?
