Well, in fact the truth is a right in the middle. Linpack is VERY easy to parallize. Earth simulator and other vector machines get over 85% of their theoretical processing power with linpack, and even clusters with relatively abyssmal interconnects are still in the 50% range.
Lots of computational problems need orders of magnitutes more inter-node communication, up to the point where linpack doesnt even matter anymore and clusters and vector computers with the same linpack score are a factor of 10 or 20 apart.
You are misstaken. We didnt STALL at 30Gflops, its just that the 30Gflops were SO much better than everything else available that it took a couple of years to catch up and overtake it.
If you average over the last 10 years, the the Earth simulator was a bump above moores law and now we are back on track.
Er, sorry, it was late at night, and it wasnt a spelling misstake, but a mixup. (pfitzer is a perfectly good name). And yes, like the other poster (who is deeper in the field than me, i only do astrophysics as a hobby besides my normal physics) already told, the VLT is built to be used as an interferometer using all 4 mirrors and 40m or what it was as baselenght.
hehe. and i guess what bad impressions hubble would make with the aliens... "Oh what a low civilisation, they actually put a wrong mirror into that telescope..."
er, well you are a trolling hippie, because the few tons of material that deorbit every year (and the few parts that actually hit the botton and not evaporate) are SOOOOOO important against all that crap thats thrown into the sea otherwise (trash, sinking of boards, sewage, crashing airplanes, ect). Or not. I guess it will take a few decades until even the equivalent of a single sunk ship from WW2 will have deorbited. So it really doesnt matter.
Fact is its not better anymore. At least in the visible range the VLTI is better. But of course there is no alternative to a space based telescopy in the UV and IR (which is now done by the pfitser), but the main problem is that keeping it up there isnt the problem, but the fact that its getting OLD. Nearly everything needs an overhaul.
Well, you arent done with changing the controller, because there is still the password on the discs. So you need to get access to them and erase the old password in order for a "blank" bios not to find a password mismatch.
Well, because of you being an anounymous ASSHOLE, you get a 0 mod and dont even apear on my screen if i dont click on the "1 reply below your threshold" link.
If people talk shit about stuff they dont know SHIT about, its only just to tread them like the shitheads they are.
And what? What is your point? yeah, they buy the stuff with mass rabattes. Yes, the stuff comes from cheap countries (or it would be even more expensive). Chipsets are too expensive? Well, you only need 200mm^2 of monocrystal SI fabbed a 0.13um grade fab (pricepoint 1Billion$ min). Even if it would cost nothing to grow the SI and run the vast cleanrooms (a cleanroom can cost a few millions per month only for the electricity of the blowers),also people work for free, no maintainmence, ect, you would need to sell 50 million of those chipsets to only get the fab in. The only reason why those things are only 20$ is because old CPU fabs/lines can be recycled.
Maybe its BECAUSE you are from one of these "developing countries" (a VERY vague thing, btw) that you have such a warped sense of price/overprice.
A mainboard costs less than filling up the gastank of my car, or a ticket for a bigger concert, or an dinner for two. They are REDICULOUSLY cheap compared to any other kind of machinery.
Sorry, no. The 3 months turnover STARTS with finished, nicely polished monocrysal wafers. The zone-melting and crystal growing stuff doesnt even count into it.
Yeah right. I mean, 50$-70$ for a Motherboard whose chipset alone costs 20$ from intel or via, not to mention the few 100 little (or not so little, like the elkos and fets of the voltage regulation stage) other parts, assembling and testing,... Its way overpriced, i see...
With this decrease of time between stories, in about 25 minutes the universe will melt because of a division by zero in slashdot HQ. And we all will be happy....
LOL Those are the best 2 i have seen this year. NIce one. Especially the "takeover" pix with the commando on wikipedia and the google "storage comparison" sketch....
Yeah, i agree about the undying ships... when trying all weapons out to find which works against shilds, at first nothing worked. I thought "damn, what am i doing wrong?" but found out that you are supposed to need 5 ships hitting one small target for 5 minutes nonstop until the shield are even half down...

And thats in a hypothetical full version that nobody has ever build or bought...

Its fallout from friday, that scared many people away temporaly.

errr...
I guess there is a slight missunderstanding about the meaning of the word "deorbiting".
Read again.

INstallers arent a problem.
There are traps that intercept them and run an installshield/ect emulation.
Sorry, no.

In soviet russia, respect gets you!
vernor vinge, a deepness in the sky.
Everything more would be a major spoiler....
To you and all the others:
I meant they didnt do a cover up (replacing their frontpage and claim "it was an accident"), but still keep the spammy one.
Well, the other reason would be: Very high signal/noise ratio.
People dont search for a word like"mesothelioma" just for fun, so its very likely to get "useful" hits.
