  1. Not a solution on How to Win on Ebay: Snipe · · Score: 1
    The problem with this solution is that a bidding war becomes a stamina war. Who will stay at their computer longest to increment the bid by a single increment every 10 minutes?

    This has been tried in the past (especially on Yahoo auctions) and it's simply not popular).

    Sniping simply changes the auction to a sealed bid auction. When it comes to bidding, just bid what you want to pay, then see if you won.

    Full disclosure--I worked for a sniping service for 6 months. I don't work there now, but would never seriously bid without such a service

  2. Re:Man... on String Theory a Disaster for Physics? · · Score: 1
    IMO, the only thing we're missing is the "gravity to the rest of it" connection, confounded by the inconvienient fact that gravity appears to be the only force in the universe which is apparently instantainious over galactic distances. Go work any celestial orbital mechanics problem, including the orbit of the earth around the sun, and try and make it work if the gravitational attraction vector is assumed to be toward where the sun appears to be now (as opposed to where it is right now instead where it was 8 minutes ago when that light left the suns position then). By adding any delay, the orbit falls apart, and our earth would have spiraled into the sun many billions of years ago.

    Actually, that's a common misconception of people who don't do the math of GR. But you can find many articles about relativity that explain that in fact this claim is false. GR predicts that gravity propogates at the speed of light, and that the orbit of the earth is stable. However, once you put that in, you can't simply use the Newtonian equations and have to use GR properly.

    Does it really matter, though? I'd like everyone to cut down on pollution whether it'll help global warming or not

    Yes, it does matter. I don't like brown air either. However, agenda-driven science breeds cynicism and leads to backlash. We should stop the scaremongering and simply push for clean air and water. The economics of oil are driving up the price of petroleum so that alternatives are more economical--we'll start switching soon enough.

  4. The hockey stick on Earth's Temperature at Highest Levels in 400 Years · · Score: 3, Insightful

    Ah yes, the infamous hockey stick (the chart). It was what convinced me that global warming was human-caused. Until of course I found that when you put random data into the analysis, you got a hockey stick.

    What it comes down to is that more than 200 years ago we didn't have accurate temperature measurement. Everything before that is an educated guess. And the precision necessary to show a fractional degree of change is simply unattainable.

    Where are the error bars on the hockey stick? It's shown as if we had exact data for the last 1000 years--which of course we don't.

  6. Graphical apps? on DirectX 10 Only On Vista · · Score: 1
    Well, I've spent the majority of the last six years on an OpenGL application for medical imaging and simulation.

    I'm quite aware of the proprietary extensions. OpenGL has a well-documented extension process, which ATI and NVI have used extensively. Many of those extensions were rolled into standard OpenGL (pbuffers being the most important one for me) as the standard developed.

    NVI and ATI have had OpenGL 2.0 compliant drivers for some time now. Windows has never shipped with OpenGL compliance higher than 1.1, and mobile chipsets have only gotten useful in the last few years (my first efforts with mobile chipsets and OpenGL back in 2000-2001 showed mediocre implementations--especially with the stencil buffer).

  7. -1, Moron? on DirectX 10 Only On Vista · · Score: 2, Insightful
    How is OpenGL fragmenting? Do you mean the release of 2.0 which modernizes the rendering pipeline and the shading language? I'm sure you know that OpenGL wasn't sold to MS, right? The spec is produced by the OpenGL ARB, not by SGI, MS or any other single company.

    Oh, and MS left the ARB a while back.

  8. It was odd to hear Cortana swearing on SiN Episodes - Emergence Review · · Score: 1

    That is, the actress who does the voice for Jessica also does Cortana. Only difference is the swearing in SiN. The review is basically right. $15 is a more reasonable price point. My TTGM (Time-Till-God-Mode) review is pretty good. I got through the game on hardest all the way to the final level before turning on God-mode. More variety in the enemies might have improved that. (For comparison, I've completed HL2 and Halo multiple times without God-mode, and Doom3 was so unengaging that it took less than an hour for God-mode to be switched on.)

  10. GPS to stay? Not necessarily. on Ship Logs Suggest Upcoming Polar Reversal · · Score: 3, Informative

    As the Earth's magnetic field fluctuates during transition (which we're already seeing), it affects more than the compasses. Our protection from solar radiation substantially decreases as well. Which means that cancers on Earth will go up, but also that satellites will be more likely to fail. So those satellites might just fall out of the sky sooner than you think. Nova had a really good special on the topic a while back, called Magnetic Storm.

    Try rendering medical image data as a 3D texture (well three textures actually, one for each primary image). With 300 images, 256KB per image, x3 textures, that comes out to 225MB just for the textures. I deal with datasets like these routinely, and more video memory is a welcome development.

  14. Re:Evolution/IEducation on Utah Votes 'No' to Darwin's Critics · · Score: 1

    As a Mormon in good standing, I can tell you that I don't believe the Earth was created 6000 years ago. When I taught Sunday School, I repeated the importance of understanding that science is not an enemy of religion. The LDS church has no official position on evolution.

  15. DRM on Halo 2 Only on Vista · · Score: 1
    Surely this will be a DRM flagship product?

    I loved Halo one the PC, and refuse to use console controls for playing an FPS. I tried Halo 2 on xbox and the controller was pretty much unusable. All of the Halo fans who want to play on windows will have to lock in to DRM.

    And I've already decided I won't be using Vista, so I guess I won't be playing Halo 2. No big loss since from what I hear (and from the hour or so I played it) it's more like Halo 1.5.

    Since I'm also boycotting starforce, I probably won't be playing many more PC games in the future. Time to grow up I guess.

    Right, but that's really 2 CPU packages. We run dual-CPU dual-core Athlons at work quite frequently on XP Pro. My understanding is that MS has said that per-package license will continue to be policy. I'm really hoping AMD can cram 4 CPU-cores on a package in the near future.
  19. For future performance on NVIDIA and Dell Display Quad-SLI System · · Score: 4, Informative
    Actually, one value for this is in predicting future generations of video cards early in the dev cycyle. When I worked at Intel, the research group would freon-cool the newest chip off the assembly line. They told us it basically did the job of showing us how the next (18 months away) shrink would perform.

    The same would go for graphics performance. In theory this should allow a game company to design for the next gen of graphics processors today from a performance perspective, though not from a feature perspective.

  20. Re:Worth it? on Bjarne Stroustrup Previews C++0x · · Score: 1
    And you can tell the compiler "I know" by casting properly.
    Define "casting properly". The language precisely defines the conversions. I used the conversions as the language specifies. What you're saying is that I should add a cast to tell the compiler "yes I really mean this", but that's an arbitrary decision about numerical conversions. What other programming styles do you think the compiler should enforce? I don't get a warning if I write:
    if (i==0)
    instead of
    if (0==i)
    Even though many people recommend the second style to avoid the mistype of
    if (i=0)
    Why should the compiler enforce your style choice over mine?

    The compiler is free to add the ability to turn on these "newbie" warnings. But experienced programmers should easily be able to leave them off. And extraneous casts shouldn't be added when the language has clearly defined conversions.

    If you type x = y * 3; where x is an unsigned integer and y is a float, a "type safe" language would generate a type-mismatch error at compile.
    Heaven help us from such "type safe" languages.

    In C and C++ the arithmetic conversions are a bit less strict than I'd like, but they at least allow you to do work. I know what the conversions do, and I use them appropriately. And it's a pain in the butt when a compiler tells me, "oooooh if you convert to an int you may lose data!"

    Thanks Mr. Compiler. I knew that, but I had to grow my integer-sized buffer by 1.5 and I want that integer result. At least 90% of the warnings of these conversions are this kind of worthless warning.

    UDTs don't have implicit conversions but you can define them, which is a good thing. If a language doesn't have strict typing, I'd expect it to have some sort of contract enforcement. Otherwise it's really hard to define safe interfaces.
