Linux Newsletter Monthly Summary

by The O'Reilly Network Editors
Linux Newsletter for 02/12/2003

Dear Reader,

In case you missed them the first time around, here are four great articles from the Linux DevCenter in the past month.

Migrating from a proprietary to a free Unix has its advantages. Speed, stability, cost, and convenience make Linux and the BSDs appealing. Unfortunately, sometimes you have an application without source and without a free counterpart. That's where binary compatibility comes in. NetBSD's Emmanuel Dreyfus is behind the Darwin and Mach binary compatibility layer, which allows running Mac OS X binaries on NetBSD. ORN interviewed him about the project, the hopes for making migrations a little easier, and a similar projects in Linux space. Read more in Emmanuel Dreyfus Interview.

Howard Wen's been looking at the state of games in Linux lately. He first found Falcon's Eye: A Graphical Makeover for Nethack. Not content to leave it there, he followed up by interviewing Jaakko Peltonen, the game's creator. Find out how Peltonen pulled off cross-platform compatibility while retaining the essential flavor of the venerable Nethack.

Spam's been getting worse this year, but there's hope. A recent paper on the statistical analysis of e-mails popularized a spam identification technique called Bayesian filtering. Of course, you don't have to be a statistician to clean up your inbox. Oktay Altunergil explains how to run a simple Bayesian filter with the impressive Sylpheed-claws mail client. Read more in Bayesian Filtering with bogofilter and Sylpheed-claws.

One of the weaknesses of the setuid model is that applications usually only need a few privileges. Having the power to do more than they need gives malicious users the opportunity for mischief. There's a movement afoot on the BSD side of the house to limit the damage with a nifty utility called systrace. Michael Lucas explains how security is made easier in Systrace Policies. (A Linux port may be found at Systrace for Linux.)

See you next month!
