  1. Re:quake (the game) cripples internet on Quake in Taiwan Cripples Internet · · Score: 1

    That reminds me that when I tried to play Quake 2 with a friend using a serial null-modem cable, the ping time went wild when we fired the railgun... It's a bit surprising that they didn't catch that during game testing...

    things you eat and how you behave determine some of the outcomes

    That's if you believe in free will. People who don't would say that the things you choose to eat were in fact already determined from the beginning (being dependent on the initial conditions in the big bang).
  3. Re:Ok, I'll bite. on Vista vs. Cairo - A Microsoft History Lesson · · Score: 1

    It's funny that the parent post is moderated to 5 while this reply, which is factually accurate, only has 1 point...

  4. Re:Game Theory on The Many and Varied Games We Play · · Score: 1
    A few more facts/examples might help some people to understand why Jerf is correct:

    • Consider a game such as Tic Tac Toe where both players can force a draw if they play perfectly. in this case, all the minimax algorithm will do is play for a draw, until a mistake is done by the other player. The minimax algorithm will *not* risk anything such as trying to induce the opponent into errors, since it is basically trying to minimize the worst outcome of the game.
    • Suppose that a chess engine finds that it can force a checkmate against a human player, assuming that the human player doesn't see the only way out of it, which is to make a move which will only be understood after 20 moves from each player... Even if there is a high probability that this checkmate would work against most humans, the Minimax algorithm will *not* go into it since it assumes that the human won't make that error. This is why the Minimax algorithm doesn't guarantee the best score possible against humans. If you can model the errors made by human players (and you're willing to trust that model), you can make a program which will score more points against human players than a program based on the Minimax algorithm.

    Man, you're brunch conversations with friends must be downright strange.

    Probably not stranger than writing "you're" instead of "your", however...
  6. Re:Soooo unlucky.... on Nintendo To Replace Wiimote Wrist Straps · · Score: 1
    most people tend to face their TV when using their Wii rather than the fireplace.

    This reminds me of some scene in the book Gulliver's travels... :P
  7. Re:Nothing new here on How Skype Punches Holes in Firewalls · · Score: 1

    What attack vector? The point of the story is, if you let the network make UDP connections, the network can make UDP connections to anyone. So what?

    While this is a cool technique, I had heard about NAT2NAT years ago... This is not a new technique, by any means.

  9. Re:If this keeps up... on Melting Coins Now Illegal In the U.S. · · Score: 1

    So if one really wants to save money, one should pay with cash every time the amount would be rounded down, and with card every time it would be rounded up...

    Europe and the UK? :)

    That sounds very nice, but even if it's feasible it's not the hospital's responsibility to develop such a new technology.

  12. Re:I dont *hate* Microsoft..... on Why Does Everyone Hate Microsoft? · · Score: 1
    I explained there exist a number of companies, such as Trolltech out of the EU

    Last I checked, Norway didn't belong to the EU...

    Actually, most Hello World programs aren't perfect. For example, most of them don't do error checking, and the ones in C often don't use a standard main function...

    That, of course, depends on your definition of "friend".

    What, the horrible blinding green color on that webpage? :S

  19. Re:My solution for digital photos? on Archiving Digital Data an Unsolved Problem · · Score: 1

    That's so silly. The effort of writing a C compiler (it doesn't even need to be a *good* C compiler, just a working one) is trivial... Plus, it's not actually needed, since any decent programmer should be able to understand what the code is doing and write a new decoder from scratch in whatever language is the current fashion at that time...

    What's your point? From a few google searches it seems that the speed of light in fiber optic is as much as 2/3 of the speed in a vacuum, so is it really different? Not even an order of magnitude....
