  1. Re:Use the GPU and a suitable language on CPUs/Compilers for Numerical Simulations? · · Score: 1

    That paper is probably out of date now. The new PCI Express boards are supposed to directly address the bandwidth issues.

  2. Use the GPU and a suitable language on CPUs/Compilers for Numerical Simulations? · · Score: 1

    In terms of sheer numerical processing ability modern GPUs leave CPUs standing in the dust. Get a top of the line nVidia graphics card. Preferably PCI Express because the big bottleneck is getting data back out of the card. The hardest part is that the code typically needs to be 'disguised' as a rendering problem but if you use a programming language like Brook you can write in a C-like way and get amazing performance without having to touch a graphics API. One catch is precision - but many iterative algorithms are fairly robust in the face of imprecision.

  3. Re:Lower the volume instead of muting it! on Lucasfilms Nixes Star Wars Live Screening · · Score: 1

    They do have such a law. Lucasfilm enter into a contractual arrangement with theaters and they have some pretty precise rules about how the sound is played as part of that contract.

  4. Re:Ok, even I have to cry "Lefty" on this one on US Presidents on Presidential Power · · Score: 2, Insightful

    Since when has "plain text" ceased to be a suitable medium for news? Do we only accept something as newsworthy if the text is full of hyperlinks and wrapped around animated ads?

  5. 2 dozen people on Astronaut Wants Space Program With No Frills · · Score: 1
    I really don't think so. The number of material scientists in the world is pretty large and the number of people working with buckytubes is not inconsiderable too.

    Additionally I think you can make pretty good judgements simply by looking at the record of achievement by people in related fields. Without knowing anything about the fabrication of electronic components I can probably make pretty accurate estimates of the processing speed of fast CPUs in 5 years time, say. I don't see why this procedure should magically fail for material science.

  6. Re:Nothing will further space exploration more tha on Astronaut Wants Space Program With No Frills · · Score: 0, Troll
    People like you and I (and Bush) shouldn't waste our time strainging our tiny little brains to figure out why it won't work
    Speak for yourself (and Bush). We're not all HTML and Java weenies round here.
  7. Re:My god on Automotive Tires Without Air · · Score: 1

    I was thinking of applying for a job with the guy who designed it!

  8. Re:Nothing will further space exploration more tha on Astronaut Wants Space Program With No Frills · · Score: 1

    I think a Warp Drive might be more useful. Or maybe transporters. Just as feasible too.

  9. You don't have to check your tire pressure on Automotive Tires Without Air · · Score: 3, Interesting

    Some cars check it for you.

  10. Can we just switch policy? on Carbon Nanotube Antenna for Light · · Score: 3, Funny

    And post stories only when people discover things you can't do with nanotubes?

  11. I'm making the movies, so I should have it my way on George Lucas Speaks on Trilogy Changes · · Score: 2, Interesting

    That's from George Lucas and it typifies what I've always believed about directors - they work best when under financial and artistic constraints. A great example is The Matrix. The Wachowskis had a fairly limited budget and created a masterpiece. For the sequels they had a vastly larger budget and made turkeys. In fact, I think their best movie was the fairly low budget Bound. The same is true of many other directors including Lucas. Left to their own devices they'll make a mess of things. It really makes me cringe when a director says "now I can make the movie I've always wanted to make". When that happens you get self-indulgent crap. But the goal of film is to indulge the audience, not the director.

  12. RHex is also cool because it swims on Cockroach-Like Robot to Help Explain Animal Movement · · Score: 4, Interesting

    I discovered this by reading the story about RHex here.

  13. The engineers at google must suck... on Google's Math Puzzle · · Score: 1

    ...if they need to display posters like that in order the find the solutions to their problems. And they're not even offering to pay the people who solve them.

  14. Re:100% secure? on A Working, Quantum-Encrypted Intranet · · Score: 1

    That's like saying that you don't need to heat water to boil it, just wait for the atoms, by chance, to arrange themselves into steam. If you use a big enough RSA key, one that is still practical for sending things like emails, there is no group on earth with enough compute power to be sure of cracking your key using the best algorithms known to mathematicians working in the field today. RSA, with big enough keys, is as good as uncrackable.

  15. the primary value on Steel Bolt Hacking · · Score: 1

    Erm...that's what you say to the mainstream media but you can tell the truth here on slashdot. You know full well that very few competitive lockpickers are doing it for anything other than entertainment and very few are actually going to feed back their knowledge to help lock manufacturers improve their products.

  16. Re:100% secure? on A Working, Quantum-Encrypted Intranet · · Score: 1

    Except that codes that are more or less uncrackable already exist. Systems get hacked, not because the code is cracked, but because the weakest link in the chain is typically not the code itself.

  17. Are your neighbors uglier than you? on Replace Your Windows With LCD Panels · · Score: 4, Funny

    Well they tried exorcism on the individual pixels first and that didn't seem to work.

  20. Some people are just good... on Red Brains vs. Blue Brains? · · Score: 1

    Except that conservatives like to believe that gays 'choose' their orientation and that kids are easily 'perverted' by exposure to homosexuality. The truth is that conservatives and liberals have an agenda quite different to what you are talking about and will pick and choose whichever part of nature/nurture serves their ends.

    It might be that a gene that predisposes you to cancer makes you prefer to live somewhere that gives you clear reception of the local cheesy pop music channel.
