  1. Re:Am I missing something here? on 'Zodiac Island' Makers Say ISP Worker Wiped an Entire Season · · Score: 2

    Probably the worker saw the FTP server full of copyrighted movies, and thought "better wipe them before we get any legal trouble; to be sure, better also delete the backups." :-)

    Actually March 31st was world backup day.

    Add to that, there's the status symbol of the "Twitter Ratio." Pretty much it's #of followers/#people you follow.

    The higher the result, the more awesomer you are.

    Well, then it's easy to get incredibly awesome: Don't follow anyone, but find at least one person who follows you. This gives you a twitter ratio of infinity. Try to beat that!

  4. Re:Phong shading? on Pioneer Anomaly Solved By 1970s Computer Graphics · · Score: 1

    The universe could well be modelled by a small black box around Pioneer with temperature 2.7 Kelvin. It "absorbs" any radiation going into it and sends 2.7 Kelvin thermal radiation. Indeed, probably they neglected the 2.7K radiation anyway, so all that remains is a black box. That's about the easiest part to model.

    However I guess Pioneer has not completely diffuse reflection (it probably has some shiny metal parts), and that would be a problem for radiosity.

  5. Re:Excuse my ignorance on Pioneer Anomaly Solved By 1970s Computer Graphics · · Score: 2

    The important part is not the mass, but the momentum. Total momentum is conserved, therefore to accelerate (i.e. to increase your momentum) you'll have to emit something carrying the momentum difference (because in space, there's nothing else you could transfer your momentum to). One way is just to throw some matter out, which then of course has backwards momentum, thus giving you forward momentum (remember, the sum must be zero). But radiation also has momentum, therefore you can also emit radiation backwards. Indeed, if only looking at the energy needed, the best propulsion method would be to send a strong laser beam out of your ship, because light has the least energy for a given momentum (according to Einstein, E^2 = (mc^2)^2 + (pc)^2, and for light, m=0).

    I didn't know that 20, 21 and 35 are prime numbers ...
    However, the three indented parentheses in the 5th-last to 3rd-last line have 19, 20 and 21 characters, in that order.

    Indeed, the last lines (those where everything is in parentheses) have the following numbers of characters in their parentheses:
    23
    19
    20
    21
    35
    11,5

    Also, the three indented parentheses look very similar; only a few characters are different between them.
    And of course, "NCBE" occurs almost everywhere at or near the end. And "TFRNE" seems also quite frequent. Also PRSE.
    Somehow I get the impression that "E" tends to be an end of a word (or code unit, or ...). The second note confirms this, because the dashes come almost always after an "E".
    "WLD" seems also a frequent combination.

    Well, apart from the encryption part, I can see how it could be used for dramatic effect: If the time is working against them, and they are of course doing other things while the disk gets imaged, and of course they constantly get to points where they really would need the information of the disk, and every time they look if it is ready, it isn't ... and then, in the last moment when everything seems lost, it's finally finished and they can look up the missing information (well, unrealistically the imaging process already decrypted that thing ...).

    The genetic software world which runs our bodies still can get viruses after billions of years. And that despite us having a quite sophisticated AV system in our bodies.

    And even our mental software is not always immune against malware. Proof: 9/11.
    Or at a lower scale: Every popular myth out there.

    Indeed, I would not be surprised if genetic viruses could manipulate our mental system in order to spread (e.g. if AIDS turned out to make infected people want more sex).

  18. Re:Goodbye Nokia, it was nice knowing you. on Nokia - No More Symbian Phones After 2012 · · Score: 1

    It wasn't about Symbian. It was about Qt, an target which would have allowed developers to program for current and future devices (and desktops).

    I wonder why they didn't port Qt to Windows Phone 7. It would have enabled to bring all the applications written for the other platforms to WP7 with minimal effort, thus giving them both the applications already developed for the other phones using Qt and the applications developed specifically for WP7.
    Given that they had Qt both running on (desktop) Windows and on (Linux based) phones, porting it should not have been that hard.

    BTW, did the current Qt copyright holders also get the rights needed for putting it on phones? If so, they could release an Android version of it ...

    Lisp is based on Lambda Calculus from the 1930's.

    Plankalkül shared an idiosyncratic notation using multiple lines with Frege's Begriffsschrift of 1879 (dealing with mathematical logic)
