  1. Re:The Plans are obvious.. on The ROBOlympic Games · · Score: 2, Funny

    Actually, it reads:

    Entrance is free for children under 7."

    Children that tall are usualy still in their mother's womb..

  2. equivalent on Fast CD-R Drives Make For Twice the Piracy · · Score: 1

    "the equivalent of 421 CD-burners"

    Obviously they mean "CD-burners of which the total speed equals that of 421 single-speed burners".
    Or about 9 48-speed burners..

    Hey, I've got that at home!

  3. neurosurgeon on What's It Like to be Google's Boss Techie? · · Score: 1

    In the staff section you say you have a neurosurgeon on payroll. I can't possibly imagine what job he/she has, except for operating on linux-machines with hart problems (yes, linux has a hart!).

  4. scrolling errors on First Reviews of Mozilla 1.0 Roll In · · Score: 1

    I've been using mozilla over a year now in linux. It has never failed me, that is in pages that are written in good html, not that crappy stuff some people write: When it runs under ms internet explorer they are happy because, well everybody uses internet explorer, right?

    The only thing that I experience while scrolling is that text is broken: at some height IN a text line, all pixels above are just one pixel to the right (or the left) of the pixels underneath.
    I have experienced it mostly on /. , because it is a site that needs scrolling, and has a lot of text :)

    Has anyone else noticed this?

  5. holographic storage on Terrabit Per-Square-Inch Hard Drive · · Score: 1

    This is an old article, but apparently they never got any further on the subject:
    http://www.sciam.com/askexpert/computers/computers 2.html
    I suppose that if one can get mirrors to move fast (9ms to be faster than normal harddrives) and accurate, wich is probably just what they already can with normal hardrive heads moving much faster (the average access time from harddisk drives is determined by the speed the disk spins, not the speed of the heads), the only problem left is getting the data-density up..

  6. Using worms for security on How to Own the Internet In Your Spare Time · · Score: 1

    What if microsoft wrote worms to close security holes in their software?
    They could write a worm like they can write a service pack, but with the advantage that people who don't frequently check for service packs, also are protected against future attacks.

    The worm's instructions could be:
    - download security patch (however this could take down the security-patch-server)
    - apply security patch
    - spread
    - kill self (after some time, or after all possible ip's are scanned, or ...)

    While it is the system administrator's duty to keep the server secure, this method could secure the server when he is getting a nap, or some coffee. Especially since the paper describes attacks in less than 15 minutes.

    It could be implemented using a "yes, I want that service"-box, so that one who doesn't like this can opt out of the security check.

    Also, one could use some registration check, so that only people that payed for it, can get this service.

  7. multitasking games; windows vs linux on GeForce3 and Linux · · Score: 1

    The one thing that still disturbs me, is that an untweaked linux-system can't get the same gameplay as an average windows-system (yes i know; `system' may be a bit high up the ladder :)
    Sure you can get higher average and maximum framerate's, windows just has better gameplay.

    The reason for this is that linux is a real multitasking system. Unlike in windows, where the system is totally taken over by the program that uses the most cpu-time (or is in the foreground), linux just leaves it all running at the same performance.
    This means that if you are playing some 3d game, and someone accesses your server, of perhaps just some program you are running just needed disk access, that program gets all cpu (for just a very short time). It results in a sudden drop in framerate.
    One can try to set the priority of the 3d game to -20 for example, but another program will always get the cpu for a short time.
    The current solution for this (the problem also shows up at decoding dvd or mpeg) is running only programs that are really needed. Or off course buying a dual-processor system :).

    But perhaps there can be something done at multitasking-priority level. Getting the system to switch faster between the programs maybe (because an actual multitasking-system would need a cpu for every possible task it's running), or perhaps a whole different approach: instead of giving a program the cpu for a short period of time, getting tiny bits of the lower-prioritized program processed in between the other program (game in this case). It could be however that this causes a higher use of cache, but I am not that good informed about that..

    In any case, this is the real reason why people still want windows for playing games, and as long as this problem isn't handled, it will always be a bit more confortable fragging on windows.

  8. Re:Bernoulli Effect on What Bernoulli Missed About Flight · · Score: 2

    Big airplanes, like Boeing 747, are actualy very slow and heavy objects. They have to use all possible advantages they have. That's why they have their wings shaped like that. And you can say whatever you want, but is isn't easy to get a boeing 747 flying upside down. Just try it sometime in some flight simulator.
    It's just as qwertykid says; The airflow sticks to the airwing. If one should take flat wings, the angle of attack is too big, and the plane would stall (which means that the lift from the top of the wing is gone, the lift from the bottom is still there).
    The solution to this, when building your own model-plane, is getting a better engine. Then the plane would fly faster, and the lift you would't get from the top of the wing is compensated with the lift you'd get from the bottom of the wing.
    This is why boeing has its wings shaped like that. One can't compare this to an F16 that has to be as manouverable as possible, and has to be able to pull negative G's.
    There are other solutions for getting the plane in the air, but this is the optimal one.
