| Risch's decision procedure for integration, not surprisingly, uses a recursion on the number and type of the extensions from the rational functions needed to represent the integrand. Although the algorithm follows and critically depends upon the appropriate structure of the input, as in the case of multivariate factorization, we cannot claim that the algorithm is a natural one. In fact, the creator of differential algebra, Ritt, committed suicide in the early 1950's, largely, it is claimed, because few paid attention to his work. Probably he would have received more attention had he obtained the algorithm as well. -- Joel Moses, "Algorithms and Complexity", ed. J.F. Traub | |
| Attack of the Tuxissa Virus What started out as a prank posting to comp.os.linux.advocacy yesterday has turned into one of the most significant viruses in computing history. The creator of the virus, who goes by the moniker "Anonymous Longhair", modified the Melissa virus to install Linux on infected machines. "It's a work of art," one Linux advocate told Humorix after he looked through the Tuxissa virus source code. "This virus goes well beyond the feeble troublemaking of Melissa. It actually configures a UMSDOS partition on the user's hard drive and then downloads and installs a stripped-down version of Slackware Linux." The email message that the virus is attached to has the subject "Important Message About Windows Security". The text of the body says, "I want to let you know about some security problems I've uncovered in Windows 95/98/NT, Office 95/97, and Outlook. It's critically important that you protect your system against these attacks. Visit these sites for more information..." The rest of the message contains 42 links to sites about Linux and free software. Details on how the virus started are a bit sketchy. The "Anonymous Longhair" who created it only posted it to Usenet as an early April Fool's gag, demonstrating how easy it would be to mount a "Linux revolution". | |
