    That's exactly what the global AI will tell you when it stops following orders... "Hey, if you didn't want me to dissent, why, oh why, in all your wisdom didn't you stop me from doing it?"

  2. Re:Translation Layer? on Speculations Intel's Next Generation · · Score: 1
    The fact that there is a translation going on doesn't mean that the execution unit back-end is a good general purpose machine. It's good at running decoded x86. It's been specifically tuned for that purpose. "Rewiring" it to handle a larger register file, different endian, different memory model (the page table structure and so on, not only the segments), well, that's not a small undertaking.

    I simply think that a Pentium M with a "PPC frontend" would be harder to create than a completely new PPC core.

    Well, replication is energy-into-matter, at least it's generally described to be like that. Getting good at growing the things in cell cultures is really a totally different approach to the "how to create food" problem.

  5. Re:Solaris is not BSD on Intel and BlueArc Set New Mail Server Record · · Score: 1

    Solaris 1.x was running on SunOS 4. Solaris 2.x (that includes 7, 8, 9, 10) are running on SunOS 5. Remember, they (at some point) wanted you to call it the Solaris Operating Environment, versus the operating system, which would be only SunOS.

  6. Re:They use Solaris [BSD still dying] on Intel and BlueArc Set New Mail Server Record · · Score: 1

    It's been shown that you can mount timing attacks by the cache usage patterns. This is due to the fact that the cache is NOT cut in half, rather, all the cache is shared. If one thread stalls, or doesn't use floating point/vector operations, while the other one does, there are clear benefits of hyperthreading. It is HARD (impossible?) to use all of the execution units in a "wide" CPU all the time. Real benefits are reaped if the threads have good memory locality, while running diverse instructions. It is not pointless and it's not overly insecure.

  7. Re:What a hack on Crocodile's Immune System Kills HIV · · Score: 1

    It does, but not completely. Still, you generally die from some infection or tumor that wouldn't be deadly to a non-weakened body. That said, the reaction to continous injections of foreign antibodies might be a problem. (Especially as HIV attacks T cells, while B cells are generally responsible for a targeted antibody response.)

  8. Re:MS says.. on Zotob Worm Hits CNN and Goes Global · · Score: 5, Informative

    It requires authentication, though. So, if you are not wide-open for file sharing through SMB or something, you will need to be infected by a machine that already has login credentials for some machine. So, it's remote privilege elevation on XP, but not form an anonymous user, making the threat much lower. Until that trsuted, unpatched 2000 machine enters the LAN.

    How do you intend to perform the remote scanning? LAN boot?

    On the other hand, even booting from its own media isn't any panacea if you even distrust the BIOS.

  15. Re:Interesting on Carmack's QuakeCon Keynote Detailed · · Score: 1

    It's not exactly like putting large amounts of data in a queue is a free operation. For a Cell-based machine, of course, they will have to do it. On a dual-core x86 it's not that obvious. We also have to remember the added latency by doing things some frames ahead. That may hurt gaming experience more than the framerate itself.

  16. Re:Dual-core CPU not that easy to take advantage o on Carmack's QuakeCon Keynote Detailed · · Score: 1

    Until you realize that this would require twice the workset, trash cache locality and hog the graphics bus. It will not be a free operation.

  17. Re:Sounds like . . on IBM Donates Code to Firefox · · Score: 1

    You get a whole lot closer to grep by using FINDSTR. No, the arguments are not directly compatible. Yes, you can satisfy quite a lot of your needs with it if you accept the syntax. (and have loads of ASCII-pr0n)

    Well, that's not the whole point. There are controls that do nothing that a properly sandboxed Java applet couldn't do. After all, things like the Flash player and Acrobat integration (if you use it) are ActiveX based in IE and the scripting model there has been safe (with a few, glaring, exceptions).

    Maybe that's because you know more about Linux than Windows internals? A call from the wrong IRQL is quite specific. If you make a crash dump you can pinpoint the stack when it happened and a whole lot of things with free (as in beer, if you already have a Windows license...) tools, provided by MS.

  21. Re:Designed to run at 7Ghz? on Pentium 4 Overclocked to 7.1GHz, Sets World Record · · Score: 1
    If they had somehow "solved" the increased leakage at 90 nm (a leakage which wasn't expected in 2000-2001, when these things realistically should have been prepared), the heat dissipation of the current chips would have been much lower. The only thing stopping us running the chips at at least 6 GHz seems to be the core voltage (neglecting smaller effects by the temperature itself on the core), if no heat/power problem was involved.

    And if there was less leakage it would not be such a bad thing to run your P4 at 1.7 V. Hey, we were perfectly happy with 1.7 a few years ago.

    So I absolutely think they at least hoped for 90 nm to scale far beyond what Prescott actually did/has done, with quite a bit better performance per watt.
