Fewer Shuffles Suffice

An anonymous reader writes "You may have heard that it takes about seven shuffles to mix up a deck of cards to near randomness. Turns out, though, that most of the time, perfect randomness is more than you need. In blackjack, for example, you don't care about suits. The same mathematician who developed the original result now says that for many games, four shuffles is enough. And the result isn't only important for card sharks. It helps reveal the math underlying Markov Chain Monte Carlo simulations, telling applied mathematicians when they can stop their simulations."

    This is true. It is racist, and therefore the worst thing ever in the history of history, not to consider negroes as magical super-human beings who are our superiors in every way.

    It should be a federal offense if you don't allow a negro superman to have his way with your wife, daughter, your own asshole (for the "downlows"), etc., whenever he wants. And it should be a capital offense not to worship Barack Obama for the African god that he is.

    Then, and only then, can our dream world (as depicted in Planet of the Apes) come true.
