Linux Clustering With MOSIX
This tutorial explains what it is, how you go about cluster-enabling your Linux system, and how you can benefit from setting up a cluster. By the end of this tutorial, you will have set up your own MOSIX cluster. MOSIX is a special transparent form of clustering that is very easy to set up and can produce positive results with only a minimal investment of time and energy.

User Ditches Mac OS X; User Finds Yellow Dog Linux
This is the story of a Linux PC user (namely a Red Hat Linux user) who buys an iBook under the... influense of Apple's "switch" campaign, but soon enough finds Mac OS X's UI unresponsive and its performance lacking. Trying to find an alternative OS for his PPC laptop, he ends up on Yellow Dog Linux and he claims to be happy ever since.

Administer Linux on the Fly
The /proc filesystem is one of Linux's great features, and this article gives you a thorough grounding in some of its most useful aspects. With it, you can administer many details of the operating system without ever having to shut down and reboot the machine, which is a boon for those who need to keep their systems as available as possible.

Beginning Eclipse for Advanced Developers
This paper on beyondCode.org describes the author's experience transitioning from emacs to the Eclipse IDE, from the point of view of a seasoned Unix programmer. It is not meant as a step-by-step tutorial, rather it is a description of the promises and perils one may encounter when adopting Eclipse.

Perl.com takes a look at: CGI::Kwiki.
"This article is about a new Perl module called CGI::Kwiki. With this module you can create a Wiki Web site in less than a minute. Now that's quick. Or more appropriately, ``That's Kwik!''"

Tool of the Month: Index and MultiTail
Unix Review takes a look at: Index and MultiTail.
"This month I'm going to talk about two smaller tools that I like. One is the ultimate in minimalist personal databases, and the other is an extension of an idea that's been with Unix for a long time."

Introduction to IP CHAINS
The kernel starts with three lists of rules; these lists are called firewall chains or just chains. The three chains are called input, output and forward. When a packet comes in (say, through the Ethernet card) the kernel uses the input chain to decide its fate. If it survives that step, then the kernel decides where to send the packet next (this is called routing). If it is destined for another machine, it consults the forward chain. Finally, just before a packet is to go out, the kernel consults the output chain.

Gentoo Emerges Victorious
Linux World reviews: Gentoo Linux.
"The 'meta-distro' Gentoo makes it possible to compile and configure everything on your system exactly the way you like, providing you with more structure and tools to ease the process and automate updates. Do I still like Debian? I absolutely love it. But until further notice, Gentoo is now my flavor of Linux. "

What If SCO Is Right?
Internet Week asks: what if SCO is right?
"Assume, as we have been, that there is proprietary Unix source code included in Linux. Assume that Linux vendors have been distributing this source code. Well, SCO is a Linux vendor too -- they announced on Wednesday that they are suspending distribution of Linux, but for years they did distribute Linux, under the same General Public License used for all Linux distributions. Since all the Linux vendors share source code, it's entirely possible that SCO was inadvertently distributing its own proprietary Unix code in its version of Linux. In that case, SCO would've already released its Unix source code into open source."

Java Theory and Practice: Urban Performance Legend
Urban legends are kind of like mind viruses; even though we know they are probably not true, we often can't resist the urge to retell them (and thus infect other gullible "hosts") because they make for such good storytelling. Most urban legends have some basis in fact, which only makes them harder to stamp out. Unfortunately, many pointers and tips about Java performance tuning are a lot like urban legends -- someone, somewhere, passes on a "tip" that has (or had) some basis in fact, but through its continued retelling, has lost what truth it once contained. This articleexamines some of these urban performance legends and sets the record straight.

Deploying Apache Tomcat on FreeBSD
When you think of platforms upon which you would deploy a Java Application Server, FreeBSD probably isn't the first one that comes to mind. However, Tony Arcieri hopes to show in this tutorial how easy it is to deploy Apache Tomcat on a FreeBSD system, complete with a native build of the JDK.
