    Maybe he was too busy working on Land of the Lost? :^) (That show had quite an array of writers but ad-hoc changes were common.)

    ...most widely-used asymmetric cryptosystems these days are based on the hardness of factorising large numbers...

    Don't you mean, factoring large PRIME numbers? :)

  3. Re:While... by Angry+Pixie · · Score: 1 · on BusinessWeek on Opening Apple's iTunes DRM

    The parent shouldn't have been modded a troll. The comments on Apple's own past behavior, the hype surrounding some of Apple's product lines, and attempts to dominate markets using proprietary formats like QuickTime are all fair game.

    Add to that several attempts to control every aspect of computing on the Apple platform to include software development.

    I'm reading an interesting article that discusses how Windows 1.0 was and Windows 286 were forced into being awkward and clumsy due to legal challenges by Apple. Sadly, the article lacks any reference to Gates taking Apple code with he started working on Windows.

  4. That's not the worst of it... by Grendel+Drago · · Score: 1 · on Google Updates Its Face

    Searching for "kolmogorov zero-one", the results lead to what's essentially an outdated Wikipedia snapshot, but with popups and fucking blinking ads. The actual Wikipedia text does not appear in the first ten results.

    Buncha punks. They bury a tag at the bottom of the page mentioning that they use some Wikipedia content by the GFDL, but they're still a bunch of worthless punks...

  5. Atiyah-Singer Index Theorem by amigoro · · Score: 5, Informative · on Atiyah and Singer to Share the 2004 Abel Prize
    From MathWorld:
    A theorem which states that the analytic and topological "indices" are equal for any elliptic differential operator on an n-dimensional compact differentiable C^infinitiy boundaryless manifold.

    And this is the least technical definition I have come across so far.

    Trawling thru the USENET I found:
    The Atiyah-Singer expression is:

    { ch(V|X^g)(g) * U(N^g) * Td(X^g) / det (1-g | (N^g)*) } [X^g]


    where X is a G-manifold for G cyclic, generated by g, ch()(g) is an equivariant Chern character for trivial G-spaces, U is a combination of characteristic classes which "accounts for" the normal bundle N^g of X^g (the fixed set of X) in X, Td is the Todd class, and the determinant is evident.

    Apparently the INVARIANCE THEORY, THE HEAT EQUATION, AND THE ATIYAH-SINGER INDEX THEOREM is a good source too.

    And This book:
    "The Atiyah-Singer index theorem and Elementary number theory" F. Hirzebruch and D. Zagier (Publish or Perish)
