    Not all algorithms can be parallelized that easily. Imagine e.g. a parser: You cannot parse text by having a million processors looking at one character each.

    There is a natural limit to how much cooling you can do (it tops out somewhere before -273.15 degrees celcius)

    Cooling beyond the boling point of nitrogen (-195,8 deg. C) would already cause major problems.

    I guess if the ribbon had been introduced in some OSS program instead, there would be loud complaints from all sides how the author could only be so stupid to break with the long-known standard, and would stress the importance of consistency, which obviously and blatantly is violated by those new ribbons ...

    Of course, you also have to oppose antibiotic medicine. Think of it: You are killing millions of bacteria just to save your own single life. What is it that you consider your single life more valuable than those millions of lives? Would you also kill millions of people to save your life? Probably not. But with those poor little bacteria you don't care, just because they are different enough from yourself. Bacteria have rights as well! Save the bacteria! Stop antibiotics!

    Ok, let's do the math for some realistic example: Say, you want to generate energy from the waste heat of an Athlon 64 3000+ (I've taken this model because that's the first one I've found the required technical data..

    Now the maximum temperature allowed for this procesor is 65C (that's 149F, according to Google), or 338K. Now let's assume that it's in a room with 18C (64.4F, according to Google), or 291K. Now let's assume you attach an ideal heat engine to your Athlon 64 (i.e. a heat engine which converts as much heat into usable energy as is allowed by the laws of thermodynamics). Such a heat engine has an efficiency of (338K - 291K)/291 K = 16%. Given that the thermal design power of this processor is 28W to 35W, you'd get an energy output of 4.5W to 5.6W. But note that this assumes
    • that you constantly run your processor at maximum allowed temperature (which certainly isn't a good idea; note that lowering the processor's temperature to a more reasonable 40C (104F) would about already halve the ideal efficiency),
    • that the heat engine would have a waste heat output of about 24W to 29W, which would inevitably heat up the heat engine's heat sink and thus again reduce the efficiency (unless you do a really good cooling, which probably eats up most of the energy you originally won), and finally
    • that you can actually use an ideal heat engine, and a real heat engine would have an even less efficiency (indeed, I'd be surprised if half the theoretical efficiency could be reached).

    In short: It's simply not worth the effort.

    (BTW, Slashdot ate all my degree signs; it's not my fault that they are missing.)

    When following your link, I get "Nothing for you to see here. Please move along." While I agree that not seeing the code is indeed a major obstacle to reusing it, I strongly doubt that it's what you meant to link to.

  22. Licensing on Finding New Code · · Score: 5, Insightful

    I think in order to be really useful for not reinventing the wheel, it should allow intelligent searching for licensing. That is, it should allow to restrict your search to codes with certain licenses, or even better, to code under a license compatible with any given license (or set of licenses).

    For example, if you are working on code which you want to release as BSD, it's not much help if you find code licensed under the GPL, even if that code on its own is great. Likely, if you are writing GPLed code, you are not interested in code under licenses incompatible with the GPL (like e.g. the MPL).

    Of course, the search engine cannot make a guarantee that the license will fit your needs, but then, it cannot guarantee that about the code's functionality either.
