  1. Re:Use of GPUs or PS3 chips? on Steve Chen Making China's Supercomputer Grid · · Score: 1

    IIRC, IBM is going to deliver a system that's based on POWER and Cell chips for this exact reason - no commodity chip currently beats the Cell in floating-point brute force and POWER is quite good on everything else (including floating-point).

    We will see some very interesting machines in the next few years.

    As far as killing him of leukemia 6 months from now, this would not be enough to contain any information he migh have - 6 months is time enough to write a biography.

    If this is a case of silencing him because he was about to disclose something really nasty, why not run over him with a truck or hit him with a falling brick or, even better, making him vanish without a trace? That's nothing a boat and a pair of cement shoes couldn't achieve. Although it's unclear if anyone was ever murdered with cement shoes, I could bet some money it's more frequent than with Polonium.

    If I am ever to have information people would kill me to avoid spreading, I would spread it as fast and wide as I could, leaving my potential killers scrambling for damage control and lower my value as a target.

    Of course, they might kill me later, for revenge, but later is better than sooner.

    But remaining a high value target is something really dumb to do.

  3. Re:I'd like to make a suggestion... on LSI Patents the Doubly-Linked List · · Score: 2, Interesting

    The royalties part may not work, but, certainly, bearing the costs of an invalidation and, eventually, having to pay damages for a bad patent would be quite an interesting change.

    BTW, it should be required that the patent applicant should prove it made a reasonable effort to find about prior art and demonstrate it found none.

    This patent, obviously, would fail in that regard.

  4. Re:Am I the only one? on AMD Fusion To Add To x86 ISA · · Score: 4, Insightful

    As added benefits:

    - With a public and standard ISA, you will have Linux-compatible drivers shortly

    - With a public and standard ISA, people will have a single standard to code against. Library support should be excellent.

    - While your über-FPUs/vector accelerators/stream processors (what GPUs are made of) are not GPU-ing something, they can accelerate SSL, physics processing and any other vector-friendly activity you may have. Playing Flash content, maybe.

    - GPUs are memory-hungry. The added memory bandwidth will benefit all software, not only graphics-intensive stuff.

    - There is nothing that precludes you from using a stand-alone GPU, provided you have the drivers. But your CPU will have a couple high performance units that can give it a hand. Think asymmetric SLI.

    We will see how well the idea performs by watching the Cell processor (a CPU with 8 "GPU"s attached) in the PS3. That's roughly the same idea.

    In the meantime, I bet it will work just fine.

  10. Capital punishment for torture and mass-murder on Saddam Hussein Sentenced to Death · · Score: 1

    I am not sure what this could imply for the current US administration.

    As far as I get, they are responsible for invading two countries, one of them without much of a reason, after bombing it back to stone-age (the other was pretty fucked up before they got there) and establishing a network of illegal prisons and deportations that allow prisoners to be tortured and held without right to the slightest semblance of due process.

    It's sad we came to this. Saddam should not have never been supported. The same goes to the Shah and Khomeini (who wasn't supported by the US, anyway) and a very long list of small dictators.

    It would be better to have a good enough telescope in a serviceable orbit than having a super-fancy telescope in an utterly difficult to get at orbit.

    Ease of maintenance is directly related to operational cost and, therefore, to the lifespan of the equipment.

    And, being easily serviceable would mean new instruments could be attached and old instruments removed with much more ease.

    As someone else said, there must be something escaping me. After all, there must be a good reason I am not building spaceships myself.

    BTW, why not a Moon-based one?

  14. Re:Backup for the shuttle on The Hubble Lives On · · Score: 1

    That's why we need cheap, expendable vehicles with cheap, expendable crews.

    Now seriously, wouldn't it be incredibly useful to have a transfer vehicle docked to the ISS at all times, able to pick up a stranded shuttle crew and carry them back to the ISS?

    It could even be a simple, Progress-like vehicle. How much fuel would be needed for a couple orbit transfers? And in potential rescue missions like this, it could use an ion engine to take it to the pick-up point several weeks after undocking from the ISS. It would be viable for an unmanned vehicle to take months to do an orbit change. Chemical rockets would only be used to carry the crew back to the ISS.

    Even better would be something that could attach to the now unmanned shuttle and take it to the ISS for further damage assessment and possible repairs. Ion engines could be useful here too - there would be no hurry to take the damaged shuttle to the ISS.

    I don't know if anyone noticed that, but the Pixel vehicle seems somewhat unstable with its single engine.

    You can see it here http://media.armadilloaerospace.com/2006_09_23/Pix elQualification.wmv, later in the hover, when it starts to oscilate the engine thrust vector in order to stabilize the craft. The oscilation seems to be increasing, but it's hard to tell since the hover itself is too short.

    I know they _are_ rocket scientists and, no doubt, know about this. But it seems to be a major obstacle to achieve the 180-second hover goal.

    I wonder what can be done to improve it without compromising the single-engine simplicity.

  21. Re:85 vs. 8086 on Why Apple Failed in the 90s · · Score: 1

    Of course, doing fancy things on the 8086/8088 was horrible, but the fact that it was source-compatible with the 8085 (I think) made it possible to directly port many CP/M programs and have some titles ready to run very early.

    Of course, they wouldn't be able to address more than 64K of memory, but it was not a big issue since the original PC came in configurations with as little as 16K of RAM.

    And when compared to the crazy (and brilliant) things computer designers were doing with 8-bit computers to use more than 64K of memory (Apple II, Apple III, various 8085/Z-80 designs), the 8086 is easy to program. I did a lot of bank-switching in my Apple II days and I can tell you the PC was rather boring and unchallenging in comparison.

    Again, the 68000 was so much nicer.

    When time travel becomes available we will be able to directly test these ideas.

    The PC had a fortunate spy incident in which IBM OS basics were stolen before the PC came out.

    What?! Can you explain that?

    The 8086 was very similar to the 8085, so it was trivial to translate ASM code that ran on 8085 to 8086 (if not the other way around). MD-DOS was, more or less very similar to CP/M, and porting software was easy.

    There is also IBM's misjudgement that the BIOS alone could stop clone makers, even if the PC was made with off-the-shelf parts. This, and the non-exclusive agreement on MS-DOS between IBM and MS made the clone industry possible.

    So, what spy incident are you talking about?
