Comment where's the link? playing whack-a-mole to find it (Score 1) 32

I'm sorry, I guess I'm just stupid, but when I read a story titled "Report from HOPE", I expect to find a link to a video of the presentation, or a transcript, or something. Probably I missed it -- maybe the audio link that I took for the 2008 presentation? I didn't get past the lame apologies. This has happened before: can't slashdot have an asterisk or something to indicate THE MAIN LINK REFERRED TO IN THE STORY TITLE???!! Sorry, bit frustrated here, even tho, yes, the wiki article on open source hardware is nice, but really ... . And if there is no link, which was the conclusion I finally reached after a lot of useless clicking, could you please indicate it, as you do by saying "paywalled" -- maybe "user report only, no direct link" or some such, to save readers' time?

Comment One Big Data Center idea (Score 1) 241

Yes, the whole idea in that film was that central control (hmm, like Ma Bell?) was crucial. But even then DEC was showing that IBM's fanatically controlled One Big Data Center idea was crazy. The failure of Japan's 5th Generation, France's central system, AOL, etc. followed. To date myself, I remember working at HEW in 1973, and bringing my punched cards to the computer center, where I was at the mercy of the arbitrary manager. I hated it! The control freaks ruled (but soon after, we got a timeshare system and were liberated). So AT&T wanted a centralized government subsidized telecommunications system run by guess who. Not surprising. I guess I should throw in Ada, too: centralized, government sponsored language. What is surprising is how effective decentralized open source projects have been.

Comment developing countries growth one of 2 great stories (Score 1) 412

Heh, the growth of the Asian tigers and then Special Economic Zones in China and India is one of the 2 great stories in our age, leading billions of people out of dollar-a-day-income poverty levels. (The other is women's rights for half the population, so 4 billion or so.) It's a really incredible story -- check out Ezra Vogel's recent book on Deng Xiaoping for very cool info. For example, right after Deng got back in power in 1977, with responsibility for education, he made the universities use impartial entrance exams rather than the recommendations of party officials; of course, this caused problems so late and schools opened a bit late! But yes, it's good that outsiders try to improve these facilities; the complaints are just. But please don't forget the ENORMOUS benefits in lifting so many people out of poverty. Frankly, I never thought I'd see it in my lifetime.

Submission + - Ask Slashdot: how to build a homebrew supercompute

eoi writes: Hi, I've been thinking about building a home computer, and realized that I'd really like to try an inexpensive hpc computer, if possible. I do math research in combinatorics, and most of my problems are exponential, so this is actually a real need for me. The tail end of the HPC 500 (top500.org) list has about 50 teraflops, so I thought 5 teraflops might be a good goal. But the Wiki flops page http://en.wikipedia.org/wiki/FLOPS lists the cost last March as $1.80 per gigaflops. Is the cost less now? Is the right method gpu's or cpu's? Or PS3's? I wonder what you could build for $2000 or even $1000.
