  1. Re:Does the clock speed matter that much? on Apple to Announce the Power Mac G5 at WWDC? · · Score: 1
    There is only so much power that you can push through a lower clocked processor before it becomes pointless.

    *Sigh*.

    Read the above statement carefully...does it even make sense? No.

    Read my lips: clock speed has nothing to do with processor power. The exact auto engine analogy (which nobody seems to get right BTW) is RPM versus horsepower. Sure that little VW four-banger engine will rev to 8,000 RPM, but it still doesn't put out 300 horsepower like the V8 at 4,500 RPM. RPM is like computer clockspeed. Horsepower equates to physical work, while computing power equates to actually doing computing tasks.

    Some of the extremely powerful explicitly parallel computers ran fairly slow processors, clockwise. However, by using thousands of them, they got a lot of work done. Modern microprocessors use parallelism hidden within the CPU (and normal instruction stream) to accomplish more per clock cycle. How effectively this is done, and how efficiently the processor interacts with memory are just as important to system throughput (computing horsepower) as clock speed.

    The lower-clocked 64-bit offerings from AMD and the PPC 970 are both looking more interesting to me than the latest offerings from Intel. :-)

    You should never exercise stock options unless you are going to sell them immediately. You don't exercise them to hold them. That's Stock Options 101, any advisor (except maybe somebody in your company) would tell you that. If you had enough options to make "real" money then you should have spent a few bucks and got some advice. (Note, the "you" here is the hypothetical "you", not an attack on glock.)

    There are reasons to exercise them and hold, in the sense that the person may have left the company and been forced to use the options (obviously thinking the stock would have future value) while possibly not being able to sell the stock for a certain period.

    None of this applies to me personally, I did read about such circumstances though. Some were millions of dollars in debt to the IRS.

    Wrong. It was Soviets who defeated Germany. Anyone who claims otherwise doesn't know what they are talking about. Even after Normandy, about 70% of German troops were fighting the Soviets, and Soviets fought them ALOT longer than Americans did.

    The original poster said it was an important "turning point". What do you think would have happened if Germany hadn't been so worried about the Western Front? Also don't forget about American aid to the Soviets, which was crucial.

    Further, you're ignoring the important fact that America was the only power to have substantial forces involved on both fronts - and fighting the Japanese was every bit as tough (if not moreso) than fighting the Germans.

  8. Re:Basic Physics on NASA's Foam Test Offers Lesson in Kinetic Energy · · Score: 1
    This is what I don't get. The foam was not at a stand still when it hit. It was traveling at the same speed as the shuttle when it broke off and the difference in speed can be attributed to any change in acceleration, in this case negative, between the time it broke away and the time it hit. Obviously wind resistence is likely to be the primary cause of that deceleration but how much in the time/distance between breaking away and impact. That is why I think it was not as much an "aw shucks, we screwed up" kind of moment as others have been saying. There was reason to believe that the force would be low since the objects were both going at similar speeds. If anyone can explain where I am wrong I am happy to listen.

    I believe NASA analyzed the video of the foam hitting the wing to arrive at the 500 MPH impact speed. The foam was indeed mainly decelerated by the wind shear (plus the shuttle was accelerating).

    The point being, that NASA did in fact know the foam hit at high speed, early on in the process. The folks there just underestimated the potential for damage. It's not clear anything could have been done even if they had hit the panic button.

    Buuuuzzzzzz! Wrong! Nu-uh!

    That is impossible. Java has to do the same as the C code, plus the extra overhead of doing the JIT. There is no way Java can be "as fast".

    Ah, the "impossible" word. ;-)

    You're presuming that the ahead-of-time compiler can "know" everything that the JITC can. That isn't true, in many common cases.

    Another point regarding JITC compilation is that it can be for the exact target processor, something not typically the case for traditionally compiled programs.

    All that said, current JVM performance certainly varies between 'better than C++' and 'worse than C++', with pathological cases in both directions.

    The current 1.4 JVMs actually took a hit on some math operations, though that is supposed to be fixed in 1.5.

    I hope gcj gets to the point where it supports the latest language spec. The libraries are tougher, and many of them aren't needed for interesting projects. For certain applications, an ahead-of-time compiler is nice.

    By the way, for a good example of a 'fast' Java program, check out Eclipse from www.eclipse.org.

    I forgot to multiply by 10, so the actual energy is 45MJ; however, I also recalled the actual energy of a ton of TNT incorrectly; it's on the order of 4GJ. So this idea of little moon rocks having potential energy of nuclear weapons is ridiculous. (And in fact, if it was true, it would have required the Apollo CM to use nuclear weapons to slow down to return to earth).

    Thanks for the energy figures on TNT, however the 'rocks' thrown from the Moon in the story were steel-encased chunks on the order of 10 tons (10,000 kg.) IIRC. The magnetic catapults were originally used to transport grain back to Earth.

    The only energy required to make the transit from the Moon to the Earth is that required to exit the lunar gravitational field, i.e. a little over a mile per second. A magnetic catapult there is MUCH easier than on the Earth. No atmosphere is a big advantage, as is the low escape velocity. As Heinlein pointed out, the Moon sits at the top of a big gravity well relative to the Earth.

    The orbit of the catapulted rock could be calculated to directly intersect the Earth. Heinlien's setup used thrusters to perform the final entry maneuver for better control (again, this was a cargo delivery system originally). Thus you have approx. 10000 kg * (10000.0 m/s)**2 = 1.0e12 J, or 1,000 GJ. This is about 250 tons of TNT worth...not a nuclear blast by any means but significant. By the way, it was described pretty much as such in the story - Heinlein was good about getting his math/physics right. ;-)
