  1. Where does the energy come from? on Gravity Lamp Grabs Green Prize · · Score: 1, Redundant
    Energy for 50lb weight (22.7 kg) dropping 4 ft (1.22 m), g = 9.8 m/s/s:

    E = mgh = 271 J

    Assume LEDs 100% efficient and standard lightbulb 2% efficient: 2% of 40W is 0.8W.

    0.8W * 4 hrs * 3600 s/hr = 11520 J.

    Have I made some horrible miscalculation or are they claiming over 4000% efficiency for this device.

  12. Re:Image on Microsoft Challenges Google · · Score: 2, Insightful
    But what happens when Google is dead and the search engine market is cornered my Microsoft? Then the Microsoft search engine has little or no competition and development of search engine technology stalls.

    Microsoft might even start charging for searchs, now the competition is out of business and the barrier for entry into the search engine market is high what's to stop them?

    Or maybe "Microsoft Search" won't work with other browsers or operating systems. They could use each of their monopolies to support the others. Sooner or later you need to use a Microsoft search engine with a Microsoft browser on a Microsoft OS just to use the web effectively.

    If you think this is unlikely, consider how much this would benefit Microsoft and how ineffective the DOJ has been in controling their illegal activities.

    A well integrated search engine might be convienient for you now, but think of the future you would be commiting yourself to.

  13. Re:Image on Microsoft Challenges Google · · Score: 5, Insightful
    No, Microsoft searches only have to be "good enough" so the average user sees no need to change the default search engine. Then Google is dead.

    You might say that "it's easy to change your default search engine" but it's not always easy for the average user to do this. And Microsoft are hardly likely to make this any easier.

    This is why anti-trust laws exist. Microsoft can destroy another company not by producing a better product, but by producing a slightly worse product and using their existing monopoly/monopolies to push their product down the customers throat.

    I see three posibilities for the next five years.

    • Microsoft decide that the search engine market is not profitable enough and pull out.
    • The DOJ intervene and stop Microsoft from entering the search engine market.
    • Google becomes the next Netscape.

  19. Re:No, you don't have to be able to compile it, bu on Linksys Still In Violation of the GPL? · · Score: 1
    The spirit of the GPL clearly frowns apon what Linksys are doing but I'm not convinced the letter of the GPL prohibits it.
    Oh, the above was a purely theoretical discussion and has nothing to do with the Linksys case. Linksys is in violation, because the statically compiled part contains stuff that is not part of the released source. The above was about the case: "what if Linksys used a home-made compiler".
    Yes, I should have been clearer on that point.
    In my opinion where Linksys may be in violation of the GPL is that they did not release the source code in the "preferred form of the work for making modifications to it".
    Now I am curious. What do you refer to specifically?
    Say I create my own programming language (lets call it G) and write a compiler for it and keep it both the language specification and compiler secret. Then I write a program linking to GPL code and release the source code (in G).

    I think most people would agree that I have not released the source code in the preferred form for making modifications to it (as nobody has a G compiler except me). If I release my G compiler (with source code) everyone would be happy.

    Now the question is whether code for a C compiler, unavailable to the general public, which may have incompatabilities with other widely available compilers, can ever be the preferred form for distribution of GPLed code. There is no way for another developer to recreate the distributed executable with the distributed source code.

  20. Re:No, you don't have to be able to compile it, bu on Linksys Still In Violation of the GPL? · · Score: 1
    My reading of this section of the GPL is slightly different.
    The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable.
    This sentence does not say that anything about distributing executables required to build the work, only source code.
    However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
    This sentence says that you don't need to distribute source for any major component shipped with your OS unless the component is distributed with your work. It says nothing about components not shipped with your OS. It provides exceptions to the requirement to distribute source code, not additional requirements.

    The spirit of the GPL clearly frowns apon what Linksys are doing but I'm not convinced the letter of the GPL prohibits it.

    In my opinion where Linksys may be in violation of the GPL is that they did not release the source code in the "preferred form of the work for making modifications to it".

  23. Re:Umm, guys, Oregon got it right on How Would You Design the Voting Technology? · · Score: 1
    The problem is, not everybody has time to wait in line an hour to vote ...
    If they're not prepared to take a hour to vote every few years maybe they shouldn't be voting. There's been a lot of talk here in the UK recently about voter apathy causing low turnout at elections. The "solution": make it easier to vote! This doesn't solve the real problem of disillusionment with the political system and politicians in general but it does increase the turnout.

    So we have more people who aren't interested in politics voting, and no increase in the number of of people who are interested (which should be the real aim). I'm not convinced apathetic voters who spend little time considering who to vote for produce the best government.
