If that is so, should there be @ least 1 scheduler provided as default? I mean, who wants to end up with an uncompiled kernel? In no time, we'll end up with different versions of kernels, forks of plugins, and we'll end up in a pit of compatibility issues. A default one can be used as part of the failsafe.

Submission + - LA Airport Uses Random Numbers To Catch Terrorists

Submitted by Anonymous Coward on Sunday September 30, 2007 @01:34AM

An anonymous reader writes: Los Angeles International Airport (LAX) is using randomization software to determine the location and timing of security checkpoints and patrols. The theory is that random security will make it impossible for terrorists to predict the actions of security forces. The ARMOR software, written by computer scientists at the University of Southern California, was initially developed to solve a problem in game theory. Doctoral student Praveen Paruchuri wrote algorithms on how an agent should react to an opponent who has perfect information about the agent's choices.

Submission + - Novel method for universal email authentication (spamfizzle.com)

Email authentication schemes such as SPF attempt to foil spoofing by having domain administrators publish a list of their approved outgoing mail servers. SPF is sharply limited by incomplete domain participation and failure to authenticate forwarded email. A paper describes a novel method to rapidly generate a near-perfect global SPF database independent of the participation of domain administrators. A single email from an unauthenticated domain is bounced and then resent — this previously unauthenticated domain and the server listed in the return path of the resent bounce are entered into a globally accessible database. All future emails sent from this domain via this server will be authenticated after checking this new database. Mechanisms to authenticate forwarded email and to nullify subversion of this anti-spam system are also described."
