Kernel Housekeeping, Private Networks, Identity, and Binary Files

by chromatic
Linux Newsletter for 12/17/2002

It's that time again; time for the O'Reilly Linux Newsletter! 2002 may be almost done, but rest assured that we have great articles left to publish. Take, for example, the new articles for this week.

You might remember Jerry Cooperstein from his excellent article on the competing multithreading implementations for Linux 2.6. We're pleased to welcome him back this week. In Linux 2.6 Vanishing Features, he examines the evolutionary dead-ends that won't be in 2.6. What got cut? What's changed? Coop has the story.

Having dissected SSH and its configuration, FreeBSD columnist Dru Lavigne lays into VPNs. If you've ever wondered how to communicate securely over a public network, the latest installment in the Cryptosystems series explains the concepts and terms. Read more in VPNs and IPSec Demystified.

For the PHP fans in the audience, we're pleased to report that John Coggeshall is back to continue his overview of PHP file handling. This week, in Working with Files in PHP, Part 2, he demonstrates how to handle binary files. (Does anyone remember when the Web was text-only? Was that only ten years ago?)

If you're working with MySQL, and if you're practicing your normalization skills, you're probably using AUTO_INCREMENT columns. They're great, except when they're not. Luckily, Paul DuBois has provided two recipes excerpted from the MySQL Cookbook that demonstrate how to handle AUTO_INCREMENTs in multiple tables. Read more at Cooking with MySQL.

For the Open Source and Music fan in the house, Nat Torkington offers a tempting review of Slim Devices' SliMP3 player. (Your editor likes the fact that the SliMP3 code is available.)

As for extra content, it's hard not to point to Tim O'Reilly's Piracy is Progressive Taxation... and say, "Yeah, I wish I'd said that." Your editor wishes he'd said that.

No wonder we're tired ... but that won't slow us down next week. Watch for the return of Emmanuel Dreyfus and his wonderful article on threading and for Rafael Garcia-Suarez discussing Subversion for multiuser projects.

And now for a long winter's nap,
