    well... not the way the WTC was designed. It was kind of neat, actually; the shell of each tower was entirely self-supporting. By having a series of small "pillars" around the outside, it prevented the need for internal columns. If the WTC had been hollow, the walls and windows would have stood with no interior support.

    The central column, with all sorts of steel beams, was actually only needed because there had to be elevators. 3 segments of about 35 floors each, as it happens. You actually had to get off at the mezzanines and switch to get to the top.

    Anyway, the floors themselves were basically a layer of concrete and steel spanning from that central column, out to the self-supporting shell. So, the floors were by their nature not designed to hold anything but themselves. Don't view the WTC as a stack of 110 pancakes; it's more like an elevator shaft within a shell, with some incidental floors because people have to go SOMEWHERE.

    People claim that C compilers can generate code that is similar to what an ASM programmer is capable of. This is not true. A well-planned and pain-stakingly optimized C program can approach a novice ASM programmer.

    You know, maybe that's true if you have a genuine 80386 or -486 chip, but with the "Family 6" of Intel processors (p 2, 3, and 4), customized compilers produced by the manufacturer know WAY more about the particular branch predicting and out of order dispatch, to name just 2, than any novice ASM hacker.

    The problem is we don't really deal with the fundamental instruction set of the processor anymore. The intel family 6 and the AMD K6 and 7 are super-pipelined beasts which re-implement the x86 instruction set by basically having a front-end block transform those macrocodes into custom micro-ops.

    So you probably still CAN produce faster code with an assembler than, for instance, "gcc -o2," but you'd better have the block diagram for the processor sitting around to guide you, and that's not exactly a task for the novice. And I'd still be willing to bet that your margin over a manufacturer's custom compiler would be razor-thin, at best.

    Plus, there is also the inherent "beauty" of well-designed ASM code that most high level languages will never reproduce.

    Well, that's an aesthetic choice, and I'll let you have it, but I'll take the inherent "beauty" of well-commented C code any day.

    First of all, in defense of Environmentally friendly weapons: it is a generally understood rule of combat among civilized countries that civilians are not to be harmed if possible. Using dirty weapons and "scorched earth" tactics does more than just kill butterflies, it also puts the general populace at risk for years to come. So it's actually very consistent with our policy against, for example, Iraq, to try and minimize civilian casualties in all ways, including environmental degradation.

    The only way stuff like this can work on a large scale is if everyone agrees to do it (or at least everyone that matters).

    Yes and no. Nulclear nonproliferation, for example, only works if all major players agree, but we regard certain tactics as "beneath" us as Americans, such as chemical warfare and assassination. If we can raise the bar a bit more and try not to do any more harm than necessary to achieve our political ends, then go us.

Here's the letter I sent to that address; feel free use it as an inspiration for a note (not flame) of your own:

    Hi -

    I recently learned that Trident has decided not to provide chipset
    documentation for the CyberBladeXP chipset to open source developers.
    The effect of this decision is that Trident customers who choose to use
    open source operating systems such as Linux or BSD with their computers
    will not enjoy the full functionality of their CyberBladeXP video
    systems. In fact, the systems may not work at all.

    Besides being rude and alienating to your own customers, this news of
    these non-functioning systems will spread by word of mouth, and people
    will avoid Trident chipsets intentionally. At first, it will only be
    certain chipsets that they try to avoid. But, as I'm sure you know, once
    a company's name has been associated with a poor product, it becomes
    difficult to trust that company for other products, as well.

    In short, I'm not sure if I would even have bought a CyberBladeXP chip
    from any vendor. But now that I know it won't work on my system, I will
    be sure to avoid it. And now that I know Trident is upsupportive of my
    software, I will probably have to avoid your products altogether in the
    future.

    Please reconsider your decision about the chipset documentation.

Anyway, people understand golf scores, where lower is better -- they can be made to understand that lower CPI is better. So why doesn't AMD come out with an ad campaign saying, "The pentium 4's average CPI is 97, and ours is just 2. Therefore, our chip is FIVE TIMES as fast as a p4 at the same clock rate!!"
