    I don't have a problem with companies earning money with Linux based products to have to pay for using the trademark. But non-profit uses should be cost-free.

  3. Re:It's in German... on Original Einstein Manuscript Discovered · · Score: 1

    Never dared to RTFA, did you? From the page linking to the photographs:

    Page 2 of the manuscript reports the last scientific discovery of Einstein's career: the prediction of the new state of matter now called the Bose-Einstein condensate. (The 2001 Nobel prize went to its experimental observation in a cold dilute gas.)

    Actually the referred-to part in the manuscript is the second paragraph on the second page, which I'd translate as follows:

    I claim that in this case a number of molecules growing with the overall density goes into the first quantum state (state without kinetic energy), while the other molecules ditribute according to the parameter value lambda=1. The claim is therefore that something similar occurs as with isothermal compression of steam across the saturation volume. There appears a separation: One part "condenses", the rest remains a "saturated ideal gas" (A=0, lambda=1)

    The text after it explains why this happens (i.e. it contains the calculations leading to that conclusion).

    Conservation of energy is a law of physics (ok, as long as you don't include General Relativity, at least). So you don't need carbon nanotubes to conserve energy.

    However maybe it helps with conservation of entropy :-)

  9. Re:whitespace on Perl 6 Now by Scott Walters · · Score: 1
    The difference is that with non-compiler-interpreted indenting style you are actually more expressive, because you can express things the inventor of whichever indentation style did not think of.

    Look at the following C++ "n+1/2" loop (leading spaces changed to backquotes in order to prevent slashdot from messing with the indentation):
    while (true)
    {
    ``std::cout << "Enter filename: ";
    ``std::cin >> filename;
    ``file.open(filename.c_str());
    if (file) break;
    ``std::cout << "The file \"" << filename << "\" cannot be opened.\n";
    }
    Note that the special indentation tells you something about the statement in the middle: It's part of the loop control, despite being in the middle of the loop. This allows you to quickly scan all statements which are part of the loop control, even if they are in the middle of the code.

    Now, how would you do this with significant whitespace (assuming that the designer of the language didn't consider this indentation style)?

    Also, there's the obnoxious tab width problem. With non-significant whitespace it's just annoying. With significant whitespace, the correctness of your program may depend on what tab step the system uses! (Ok, probably every language with significant whitespace will define the exact interpretation of tab. Which means that on systems which don't agree with the language's interpretation, you cannot write code that's both correct and readable.)

    (Disclaimer: I don't know what Python does with tabs; maybe it just disallows them for indentation, which IMHO would be the only sane option.)

    I so wish I lived in London so I could flagrantly violate these laws and send the authorities a big fuck you.

    Well, maybe the correct strategy would be the opposite: Obey that law to the letter and don't even mention the olympic games. Simply ignore them. TV magazines don't write the olympic game time tables (you know, they are not sponsors, so how could they mention the olympic games?), the journalists (not being sponsors either) don't report about the games (they aren't sponsors, and how could you report without using those words anyway?), ... I guess the sponsors would not like that.

    Of course the problem of this approach is that it will not really work.

    I just noticed that there should be an error check after the cd command. You don't want to shred any files if the cd fails (e.g. because some newer Mozilla version uses a slightly different directory layout), and you are therefore most likely in a completely different directory.

    The same probably also applies to the creation of cookiesnew.txt. If creation of that failed, you probably don't want to shred/replace the original cookies file.

    If you have a dynamic IP, then without either cookies or you explicitly telling so there's no way for some site to determine that you are the same person who visited the page yesterday. And even with fixed IP, it's not certain (there are firewalls/proxies, computers used by multiple users, ...). A tracking cookie gives much more reliable information about identity (not completely reliable, because two people might surf with the same user account and profile, and the same person might surf from different computers, but it's much more reliable than just tracking your IP - if it wasn't, the advertisers wouldn't be so eager to use it).
