  3. Re:That's what happens when the Sun is Quiet on Cosmic Ray Intensity Reaches Highest Levels In 50 years · · Score: 1

    i don't know for sure,
    but i'm assuming that the solad wind shields us from some degree of cosmic rays.
    [ah - yep]

    the article summary is pretty bad, IMO.
    it gives the impression that the number of cosmic rays out there is more,
    when in fact it's just that the solar system's shielding is cyclic,
    and we happen to be in an extra-low minimum.

  5. Re:How convincing is the quiz? on Facebook App Exposes Abject Insecurity · · Score: 1

    by all means, share this quiz with your facebook-using friends.
    it does a great job of illustrating the issue.
    first, it shows you a bunch of stuff about you: recent posts, recent photos, birthday, etc, which your thinking facebookster probably figures the app is going to have access to. then it shows a bunch of information about random friends of yours: their hometowns, birthdays, recent status updates, political affiliations, etc. this second-order lack of privacy will probably surprise most FB users.

  7. Re:Clear up a bit of confusion here: on Initial Tests Fail To Find Gravitational Waves · · Score: 1

    great post.
    the thing i don't quite understand is why the laser is not affected by the gravity wave. that is, if it's the geometry of space itself which is contracting, it seems like the laser will be subject to that as well.

  8. Re:Thanks on Alan Cox Quits As Linux TTY Maintainer — "I've Had Enough" · · Score: 2, Informative

    this particular exercise can be a bit subtle, at least in windows. (i know this is a linux discussion, but it may apply)
    if the image is a Link, then what gets "dropped" onto the target application is the URL of the link, which many apps handle just fine. if it's not a link (ie it's an image tag not wrapped in an anchor tag) then what gets dropped is the binary data of the image itself, which fewer apps handle because it's a pita.

  9. as a hiring manager on Which Language Approach For a Computer Science Degree? · · Score: 1

    the main thing i'm going to look for is
    * someone who can think like a computer, i don't care in what language
    * someone with a portfolio: what have you actually built, and can you show it to me ?

    i would suggest focusing on the advanced conceptual stuff as much as possible. you'll pick up whatever languages you need along the way, but it's much more difficult to just ambiently pick up a proper understanding of algorithms, computational complexity, math, and statistics (and physics if you're interested in say game programming).

    i guess that's so.

    that's an interesting idea.

  13. Re:Like This on Lightning Strikes Delay Shuttle Launch · · Score: 3, Informative

    the lasers work by ionizing the air between the cloud and the source of the laser, effectively creating a guide wire which the lightning then follows from the cloud to .. the source of the laser. which in the case of an airplane would pretty much have to be the airplane, so i'm not sure it's quite what you want.

  14. Re:Just Call ChaCha on Searching Google, Where Internet Access is Scarce · · Score: 1

    indeed. just 1-800-2-cha-cha from a cell phone and leave a voice message with your question. any question. you usually get an answer in like two minutes or so. i believe it's powered by farming the voice-to-text-converted Qs out to extremely bored folks who then search google. i think you eventually can earn a bit of money if your answers are consistently 'good'. i like to ask things like "how do i weigh my own boob" or "who's the fairest of them all" or "who's cooler, cathector or cmdr taco" or "how do i drive safely in sleet".

    can this be right ?
    "The size of each knot is about five times as big as Pluto's orbit in the Solar System"

    ie, that the size of each of those little knots is 5x the size of our entire solar system ? wow.

    from http://www.naoj.org/Pressrelease/2009/07/02/fig2.jpg and http://www.naoj.org/Pressrelease/2009/07/02/fig4.jpg i would estimate the size of the entire nebula to be about 400 to 500 times the size of the solar system.

  19. Re:Nice thought, bad planning on Bike Projector Makes Lane For Rider · · Score: 1

    ot, but re "It's not like coherent light carries more energy", i recently learned that while it's true that coherent light doesn't strictly carry more energy, in tactical situations it does pack more of a punch. consider a laser versus a non-coherent light source with the same photon density/make-up. the coherent photons will have greater destructive power because they're all in phase and don't cancel each other out.

    i think the key is trusting the equations.
    ftfs: One of the many curious properties of Bose Einstein Condensates (BECs) is that the flow of sound through them is governed by the same equations that describe how light is bent by a gravitational field.

    but w/r/t the aether, i'm kind of intrigued recently by this guy who posits that the aether theory is in fact correct and that the mistake in the michaelson/morley era was assuming that matter was not itself a [standing] wave propogating though the aether.
