Threads, Cartography, GRUB, and Routing

by chromatic
Linux Newsletter for 11/11/2002

Linux has long had a love/hate relationship with threads. Some of the POSIX standards are vague, others are obscure. Fortunately, the upcoming 2.6 (or 3.0) kernel supports two competing POSIX-compatible threading implementations. Jerry Cooperstein explores both in "Linux Multithreading Advances".

A few graphics here and there can really spice up your dynamic Web site, and where better to find inspiration than Hollywood? David Sklar, coauthor of the upcoming "PHP Cookbook," has combined PHP, census data, and cartography in "Trip Mapping with PHP." Is he ready for a stint at Lucasfilms? Maybe.

Third in a series on the "Top Five Open Source Packages for System Administrators," Æleen Frisch explains GRUB. Though the free Unixes don't require rebooting often, making that process easier may make your life easier. To configure GRUB for Linux, FreeBSD, or even Windows, read more.

Finally, Iljitsch van Beijnum, author of BGP, admits that he is warming up to host-based routers. In "Running Zebra on a Unix Machine," he explains how he installed and configured Zebra to act like a "real" router. Is this alternative for everyone? No, but it may be an alternative for you.

Next week, we'll have reports from a couple of recent conferences--Trustsecure 2002 in Poland, and the Independent Game Developers Conference in Oregon. Yes, that means we'll be publishing more game articles in the near future.

As a side note, if you have a burning desire to see us cover something Linux- or LAMP-related, or if you have a great author in mind, please drop me a note. We're always looking for the best possible content.

That's all for this week. Enjoy the falling or budding leaves, depending on your hemisphere.

O'Reilly Network Linux Devcenter Top Five Articles Last Week

2. Single-User Subversion
   Revision control isn't just for distributed, multi-developer teams. Rafael Garcia-Suarez introduces Subversion and explains how to use it for personal projects.

3. Simple Things to Improve Your System's Security
   Jacek Artymiak returns with a grab bag of simple ways to enhance the security of your system. These techniques apply to OpenBSD in specific, the BSDs in general, and most Unixes.

4. Top Five Open Source Packages for System Administrators
   The countdown continues this week with number three, GRUB. This is the third installment in a five-part series on the most useful and widely applicable open source administrative tools, by AEleen Frisch, author of Essential System Administration, 3rd Edition.
