    Microsoft was already months into a massive project aimed at taking down Google when the truth began to dawn on Bill Gates. It was December 2003. He was poking around on the Google company website and came across a help-wanted page with descriptions of all the open jobs at Google.

  5. shared FSB (intel) or not (AMD); other benchmarks on Dual Cores Taken for a Spin in Multitasking · · Score: 4, Informative
    After reading the article, I realised that the frontside bus was shared. I didn't expect that. It seems to be a transitory solution in order to have the "first dual-core" CPUs on the market. When AMD releases theirs I expect them to have a superior solution.
    AMD64 has had the circuitry for dual-core on-chip memory controllers from the very first -- they just didn't have the second CPU core. For a good discussion of the differences, see http://www.linuxhardware.org/features/05/04/21/174 7217.shtml at LinuxHardware.

    A "work made for hire" is--
    (1) a work prepared by an employee within the scope of his or her employment; or

    (2) a work specially ordered or commissioned for use as a contribution to a collective work, as a part of a motion picture or other audiovisual work, as a translation, as a supplementary work, as a compilation, as an instructional text, as a test, as answer material for a test, or as an atlas, if the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire. For the purpose of the foregoing sentence, a "supplementary work" is a work prepared for publication as a secondary adjunct to a work by another author for the purpose of introducing, concluding, illustrating, explaining, revising, commenting upon, or assisting in the use of the other work, such as forewords, afterwords, pictorial illustrations, maps, charts, tables, editorial notes, musical arrangements, answer material for tests, bibliographies, appendixes, and indexes, and an "instructional text" is a literary, pictorial, or graphic work prepared for publication and with the purpose of use in systematic instructional activities.

    If your work was not in the course of your normal duties, and if it was not *specifically* commissioned by your employer, then as I read it, Federal law says the work is yours, unless you executed a proper transfer of ownership.

  11. Re:hardly unfortunate on How Not to Write FORTRAN in Any Language · · Score: 1
    It is *possible* to write C that runs as fast as Fortran for heavy math. However, it involves hand-optimizing your C until this happens.
    It is a matter of record that during the early phases of gcc and development, Craig Burley had an enormous problem convinding Richard Stallman that a family of optimizations associated with "true" arrays were worthwhile, and in fact necessary for the back end of the system. Once they were put in, performance was approximately doubled for a broad range of Fortran codes.

    And you're telling me that all this hand-optimization can be done by a routine "good" programmer, when one of the premier C programmers of the age couldn't see its value ?!

  16. My reply to Dr. Brown on Tocqueville Blames U.S. IT Troubles On Free Software · · Score: 1

    Dear Dr. Brown:

    I had one reaction to your recent article about Linux and other open source software:

    What did de Tocqureville himself say about voluntary community associations in America, how they were _uniquely American_, and uniquely effective because of the way they got out from under the rigid guild-and-government strictures of the Old World? And how are the current IP-law trends different from an attempt to reimpose those guild-and-government strictures on voluntary community associations that now (thanks to the Internet) can span the world?
    and, generally, in reaction to trends in copyright and other IP law over the past century, a further question:
    How is the present unlimited copyright term consistent with the demands of the Constutution? (Given that (1) when copyright term may be extended at will by Congress, that term is by definition NOT limited in mathematical terms (note that I _am_ a professional mathematician (Ph.D.1978, MIT)); (2) when there is no experiment that I can perform which distinguishes current copyright term from unlimited term, then that term is operationally unlimited; and (3) when no work I can find has had its copyright term expire during my lifetime, _nor can I expect such an expiration to happen during the actuarial remainder thereof_, then copyright term is not limited in human terms.)
    Absent a satisfactory answer on these mattters, I can only conclude that your claim to follow de Tocqueville is hypocritical at best.

    Sincerely--

    In very informal English:
    A manifold is a generalization of a surface (on a surface like a torus, you can move in two independent directions at any point; on an n dimensional manifold, you can move in n independent directions. Space-time is a 4-manifold.) Manifolds are the most general sorts of objects you can write differential equations and integrals on.

    Elliptic differential equations (very informally speaking) are differential equations that act like the equations for equilibrium problems.

    THEOREM Elliptic differential equation systems have finite dimensional solution sets (Hodge, Fredholm). (That dimensionality is an integer)

    THEOREM That dimensionality is a topological invariant of the manifold. (de Rham).

    The Heat Equation solution technique for elliptic differential equations leads to the computation of an integral over the manifold (not sure the best reference here, probably Friz John from NYU-Courant). (The result of that integral is a real number.)

    Theorem (Atiyah-Singer) The (real-number) integral coming from the Heat Equation solution technique is the same as the (integer) topological invariant coming from the dimensionality of the solution space.

    This says that the topology ("how many holes in the torus?") is intimately tied up with the solvability of differential equations (an entirely different branch of math); moreover, the differential equations (as occur in mathematical physics) have solution properties that generate integers (tying in to quantum mechanics).

    An interesting alternative is to flip the coin so that it lands on a smooth floor, spinning on a vertical axis. Then the uneven distribution of mass between the head-side and the tail-side will cause a bias.
