  1. Re:Buy gallium futures? on 40% Efficiency Solar Cells Developed · · Score: 1

    At least if they're operating at "100s of sun" intensities, then they only need 1/100th of the cells. Last time I looked, mirrors were still much cheaper than solar cells; so this could be useful for commercial generation. (Though not, admittedly, for your roof.)

  2. Just need to spin this the right way... on Linux (Car) Crashes At Indy 500 · · Score: 1

    In this timing benchmark, the Tux car was first to complete the race.

  3. Re:Didn't they used to use powers of 2? on The First Terabyte Hard Drive Reviewed · · Score: 1

    Let's see...

    The first disk drive used 50 disks of 100 tracks/side, each track holding 500 characters of 7 bits. It had a claimed capacity of 5MB.

    Questions?

    We should ask people with more than one to return them. 128-bit numbers are a limited resource! (Especially those that start with one or more zeroes.)

    Does anyone have random small block write performance figures?

  10. Re:Geosynchronous on Orbital Express Launches Tonight · · Score: 1

    Apparently I didn't miss it. Boeing (who built the thing) says it's only going up to 492km (circular). See Mission Overview link at this page.

    Given they're spec'ing a 1000km rendezvous range, I think the OE will have to be beefed up a bit for GEO. ("Sure we can service your satellite in, um, 37 years.")

  11. Re:Great Weapon on Orbital Express Launches Tonight · · Score: 1

    Or perhaps you contact Blofeld, set up a base in a Japanese volcano, and kidnap astronauts to take over the world!

    BTW, the article didn't mention geosynchronous orbits at all. Did I miss it?

  12. Re:Count yourself lucky you have a retail store. on CompUSA Closing More Than 50 Percent of Stores · · Score: 1, Informative

    I agree with you on the weird stocking practices---and it's true here in Silicon Valley as well as online and abroad. For example, when I ask why the shelves are empty of some item in the supermarket, the clerk says something along the lines of, "well, we don't sell many of them". Duh! You won't sell many if you're always out of them!

    P.S., For more electronic selection, try Halted (HSC) in Santa Clara.

  13. Producer countermeasures on Interview with Developer of BackupHDDVD · · Score: 0

    I haven't looked at the HD-DVD protection scheme in detail, but if it's like DVD then the content producers (CP) do have a way to retaliate. All HD-DVD players I've seen so far have a network connection on them "for updates", so....

    • On a new HD-DVD title, the CP revokes the keys of the compromised player type.
    • As soon as the compromised player tries to run the new HD-DVD, it gets disabled.
    • The disabled player gets a software update to "correct" the keys-in-memory problem (either over the update port, or new firmware is supplied on the new HD-DVD).

    So old discs can still be played, but new content retains protection on all players (vulnerable and non-vulnerable).

  14. Re:I just did that! on The Well-Tempered Debian desktop · · Score: 0

    If you're using ACPI, try downgrading to linux-kernel-2.6.16. On my A31p, resume is broken on later kernels.

  18. Why not just password protection? on Why Not Use Full Disk Encryption on Laptops? · · Score: 0

    If it's just theft you're worried about, the regular disk password schemes should be fine.

    1. You enter a password to access the drive.
    2. No performance hit.
    3. It's overridable with an admin password.
    4. You can recover the data if you're willing to pay several times the cost of the drive (i.e., thieves won't bother, espionage agents might).
    5. It's secure.
    6. It's OS independent.
    7. It's already built into your laptop (and maybe your desktop too).

    But if you're suggesting 1 2 3 4 5 to me, then the chances are that you've suggested it to someone else, and so my numbers (not yours) are likely to give me a better payoff.

  23. Re:Don't vote - go to court on Was the 2004 Election Stolen? · · Score: 0

    I was thinking along the lines of, "The government borrowing money or issuing bonds will /increase/ your long term tax burden. True or false?" and sticking in on the voting ballot. If you can't answer correctly that vote doesn't count. The questions should only discriminate against people who don't understand the issues.

    Your point about which party sets the questions is well taken though. (I can imagine things like "A pre-emptive strike is justified to prevent falling oil prices. True or False?" would stir the pot a bit.)

  24. Don't vote - go to court on Was the 2004 Election Stolen? · · Score: 0

    I think you've inadvertantly come up with a fantastic suggestion:

    People who don't vote get mandatory jury duty that year!

    Easy to enforce, and a terrific incentive to get out and vote.

    (I'd like to advocate a testing section on the voting form too---you have to get some civics questions correct in order for your vote to count---but that's a different debate.)
