  1. Re:Free Electricity on Space Elevators: Low Cost Ticket to GEO? · · Score: 2, Informative
    According to a paper commissioned by NASA, the column of ionosphere discharged would be minute, on the order of a few centimeters radius at most.

    The reason is sheer length -- even if the cable were as conductive as gold, it would have a resistance from the ionosphere down to the Earth's surface of tens of kilo-ohms (see same paper).

  2. Re:IMAP support on T-Mobile Sidekick Reviewed · · Score: 1

    I thought POP also supported getting just headers. It's less flexible and network-savvy overall, but it should be possible to delete messages without viewing their bodies or attachments. OTOH, I haven't seen a major mail client that implements this ...

  3. x86-64 has better registers on Itanium Problems · · Score: 1
    It's true that 32-bit x86 has a very poor register design compared to other architectures, but x86-64 retains them only in 32-bit legacy mode.
    • 8 additional general-purpose registers, all 64-bit (total 16)
    • 16 non-stacked FPU registers, all 64-bit
    • 8 additional registers for SSE (total 16), all 128-bit (?)
    Of course, a recompile will be necessary ...
  4. Monitor must be extra on AOL's new Linux PC · · Score: 1

    I don't see a mention of a monitor in the article -- it must be sold separately (even though one was included in the picture). Has anyone been down to Wal-Mart to check on the monitor situation?

  5. Re:Anyone remember the old school robot games? on 2002 ICFP Programming Contest · · Score: 1

    I wrote a few robots for Intergalactics -- that was fun. A simple Applet-based real-time strategy game with pluggable robot AIs.

  6. Re:Not a troll, just a question ... on AMD's Athlon XP 2700+ · · Score: 1
    You could try doing Java development with it -- that's what I do, and believe me, with current IDEs, you need every bit of horsepower you can get! Or .NET development, for that matter (although it's a bit better). I'm sure FSB speed would help too, as Java makes it easy to be a real memory hog.

    Now, admittedly, is as much about Java programs tending to be slow as it is about modern processors being fast ... (perhaps they are inextricably linked)

  7. Re:Would a reactor-style system work better? on Project Orion: The True Story of the Atomic Spaceship · · Score: 1
    You could always direct the explosions using the same design as a rocket engine.

    You might have a hard time finding nozzle material that could stand up to a fusion explosion! A pusher plate seems like about the best you could do -- you might actually want to allow some of that force to dissipate.

  8. Re:Cliff, did you READ it? on Digital Video Capture and High Frame Rates? · · Score: 1

    Seems kind of arbitrary -- why would the cycle time have to be exactly one second? C'mon, go easy on Cliff.

    Not once you see the packaging!

  10. Re:Orbital Power Plant on Going Up? · · Score: 1

    Unfortunately, as Edwards explains in his 80-page paper, a wire that long, even a gold one, would have resistance too high for feasible power transmission. I think you would need it to be superconducting.

  11. Re:Angular momentum on Going Up? · · Score: 1

    I think you could compensate at the base station.

    For all of these questions, it seems to help to think of swinging something around yourself on the end of a string. You can certainly accelerate it without touching the far end -- it just won't always go out in a straight line.

    But really, although I haven't finished reading the 80-page description by Edwards, I'll bet an answer is in there.

  12. Re:what about... on Going Up? · · Score: 1

    ... Except that that angular velocity (and its corresponding centripetal acceleration) are what keeps the thing up ...

    Lack of oxygen for 23,995 of the 24,000 miles to geosynchronous orbit -- and carrying oxygen would limit the payload of the lifters.

  14. Re:SourceDepot = Perforce != VSS on Software Engineering at Microsoft · · Score: 1
    Oh come on, can't we joke around a little? Maybe humor can even help -- if you say something completely ridiculous
    If your code <i>is capable</i> of compiling under GCC, its license is changed automatically to the GPL.
    the uninformed reader might initially respond with Whoa, that's some messed-up anti-American shit!, but I think they'd figure out pretty quickly that it was a joke.

    Or maybe it isn't ...

  15. Re:Only 128 megs? -- It can be upgraded. on Apple Offers eMacs To All · · Score: 1

    Now, I know they charge a lot for RAM when you buy it with your machine, but how are they forced to pay a very high price for it themselves? Santa Clara county issues or something? I assumed it was just a way for Apple to make a buck.

  16. Re:What about GNOME and .NET on LinuxWorld Summary · · Score: 1
    Let's be careful not to apply the same old paradigm of "wealth is limited" that Microsoft is trying to enforce in the world. I know that sounds nebulous, but what I mean is that .NET looks to be technically superior to Java, and that means it's better. Simple decision -- not naive, not corrupt. If worst comes to worst, there may be more than multiple incompatible .NET-derived platforms out there. Just as there have been, in the past, multiple incompatible C compilers.

    There's no cause to feel doomed here. I think Miguel is acting more straigtforward than we give him credit for. Besides, by his own admission, he is full of love.

  17. Re:Huh? on Ternary Computing · · Score: 1
    0.75 V is easy to detect, but hard to detect quickly and simply.

    Fast 8-bit A-D converters operate in MHz and take hundreds or thousands of integrated components (resistors, transistors). As soon as you use even two transistors in a ternary system where you could use one in a binary system, you lose efficiency.

    This Xeon is a P4-based chip. They decided that Pentium = desktop and Xeon = server (or high-end workstation?).

  19. Re:Declared war?? on Further Updates On Terrorist Attack · · Score: 1

    I would hope that unlimited spending will be conditioned by what it may be applied to -- for example, unlimited spending for reconstruction vs. unlimited spending for covert operations. Otherwise it's just too blank of a check, and I would be very nervous if Congress okayed it!

  20. Re:GAS PRICES!!! on More Links And Reports On Terrorist Attacks · · Score: 1

    Somehow, I think it would be pretty hard to find at least four capable pilots willing to commit suicide for a murderous attack of this magnitude and keep it quiet. Sure, the capability is there, but the motivation would be pretty hard to scare up.

    War in the middle east --> difficult to get oil?

    Maybe that's what people are thinking.


    We should start worrying if transportation starts breaking down though, and it gets hard to find food in the cities. But that seems pretty unlikely, since we can feed ourselves in this country. It would take a lot of panic to do that much harm.

  24. Re:Speaking as a Black Man... on Racism At Microsoft? · · Score: 1

    As a white guy, fairly privileged (strong family, good schools), I find it a constant struggle to combat racism, even in my own attitudes. It's hard not to assume all sorts of awful things about people because of their race, until I get to know them personally. I try really hard, though.

    I think the biggest problem I run into is simply the prevailing social order. I live in a midwestern town that is geographically divided -- whites live south of the tracks and blacks live north. It's really stark, and it's been this way for generations. There really are two societies . You go north, and everything is different -- language, schools, attitudes, cars, children, culture. It's hard not to get the impression that people really are different. I know that it's just a matter of history and inertia, but my goodness it's hard to overcome!
