    Typically Italians are as catholic as they can get (remember, Italy is the land where the Vatican is located!). The last thing they would seduce young American boys into is anything Islamic.

    Also your post is in contradiction with both your user name and your signature.

    {0,0,1}^2 doesn't seem to be well-defined.
    Not only isn't the formula well defined at that point (division by zero), it cannot even be continuously extended to that point, because
    lim_{e->0} {e,0,1}^2 = {-1,0,0}
    while
    lim_{e->0} {0,e,1}^2 = {1,0,0}
    and even
    lim_{e->0} {e,e,1}^2 = {0,-1,0}

  5. Actually, the Mandelbrot set is already 4D on "Mandelbulb," a 3D Mandlebrot Construct, Discovered · · Score: 5, Informative

    While the Mandelbrot set as usually defined is 2D, each point has an associated Julia set, where instead of the additive constant, the starting point is varied (the original Mandelbrot set always uses zero as starting point). Together, they give a 4-dimensional set, where two dimensions are given by the starting point (zr, zi), and the other two by the additive constant (cr, ci). The original Mandelbrot set is a cut through this 4D set at the plane zr=zi=0, while the Julia sets are cuts orthogonal to theat, at planes with constant cr and ci.

  6. Re:What does this prove? on Hackers Fail To Crack Brazilian Voting Machines · · Score: 1

    But the problem is that you cannot be sure that you are faced with the machine you understand, even if you analyzed the machine which is supposed to be there up to the last detail. That's because after all, there are still humans who have to put the machine in place, feed it with the candidates to vote on, etc. And how do you know for sure that none of them tampered with the voting machine?
    With paper ballots, you only can manipulate on the day of the election (well, in principle you could manipulate the ballot by omitting a candidate, but it's quite unlikely that this would go unnoticed). With voting machines, you can manipulate days or even weeks before. The longer the time span, the harder it gets to make sure that manipulation doesn't happen. Checking that no one manipulates during a full day may be hard, but doing so for weeks, day and night, is at least an order of magnitude harder.

    And how do I, as voter, verify that at the time I'm casting my vote the machine is indeed running that exact open source software, and not some other software which presents me with the same interface, but skews the results? With paper ballots at least I can know that whatever I vote really ends up in the ballot.

  8. Re:Hmm... on Hackers Fail To Crack Brazilian Voting Machines · · Score: 1

    Counting is a highly parallelizable process. And the number of people who can count is generally proportional to the total number of people in the country. Therefore if all other things are equal, the size of population in a country should have zero effect on the time required to count the votes.

    But looking at the result of your link, I guess you could make double-redirects by creating a link for an "URL" which actually is the post-domain part of the shortened URL. For example, creating a link to - would probably ultimately lead to Slashdot.

    I disagree. Mentioning file names isn't that uncommon, and most file names have an extension starting with a dot (command.com, word.exe, example.c, myheader.h, document.tex, document.pdf, readme.txt, ...)
    However since directory names with dots are less common, and especially not with more than one letter after the dot, maybe a good pattern to look for would be .\.[a-z][a-z]+/

    Indeed, that's what I wonder, too. It doesn't matter whether it's zip or anything else (indeed, zip is probably not the best choice in this case), as long as it's a reversible algorithm. Heck, you could even build encoding and decoding it into the web browser directly, and thus remove the need of relying on third-party web sites to get to your actual destination.

    But at least, in an oxygen-containing atmosphere, it should be possible to create an inside atmosphere with just the right amount of oxygen with relatively simple technology. Especially if the oxygen level is too high, it should be trivial (assuming the air outside is not otherwise poisonous): Simply replace a smaller amount of inside air (with too little oxygen, because people consumed it) with outside air.

  16. Re:Famous last words on Micro-Black Holes Make Poor Planet Killers · · Score: 1

    No. We are trying to investigate something which happens all the time around us, except that we cannot predict when and where it will happen the next time, and cannot just build our detectors there (not to mention that even if we could perfectly predict where those events take place we'd have to move those detectors around to those places all the time, which would be just technically impossible). Therefore we built a big machine which can produce those events on demand.

    It's not that much different from using a prism to split light into its spectrum, instead of relying on finding rainbows in order to analyze the light spectrum.

    Quantum mechanics. The radiation actually originates from slightly outside the horizon, where virtual particle-antiparticle pairs are created and normally annihilated again, just like everywhere else in the vacuum. However if one of them crosses the horizon, they cannot reunite, and the remaining particle gets a real one by "stealing" energy from the black hole.

Yes, it seems crazy, and there's no theory to support it, but there's actually no confirmed record of anyone saying "oops" exactly in the middle of an eclipse, and therefore we cannot exclude that possibility. So better be careful at the next eclipse.

  25. Re:Not the Pioneer Anomaly on Rosetta Fly-By To Probe "Pioneer Anomaly" · · Score: 1

    As far as I know, it has only been seen in Pioneers, although that may be due to the particular nature of those spacecraft that make them excellent tests for this effect.

    According to Wikipedia the problem is that other spacecrafts have too much built-in disturbance (e.g. from thrusters) to measure such a small effect.

    However I wonder why no one has built a spacecraft that explicitly avoids all such disturbances so the effect can be checked with the best accuracy possible. Also, put all sorts of additional measurement devices on it (of course only of the sort that doesn't disturb the path measurement, e.g. nothing producing large amounts of heat), e.g. to look at the matter density around (maybe there's simply more gas out there than expected, which is slowing down the space craft by friction). And of course, also measure as much of the internal state as possible, in order to find out about unexpected effects like gas leaks.
