Here's everything you need to get yourself started, courtesy of Frank Pohlmann. 11/06/2007

Getting Familiar with GCC Parameters by Mulyadi Santosa
GCC (GNU C Compiler) is actually a collection of frontend tools that does compilation, assembly, and linking. The goal is to produce a ready-to-run executable in a format acceptable to the OS. For Linux, this is ELF (Executable and Linking Format) on x86 (32-bit and 64-bit). But do you know what some of the GCC parameters can do for you? If you're looking for ways to optimize the resulted binary, prepare for a debugging session, or simply observe the steps GCC takes to turn your source code into an executable, getting familiar with these parameters is a must. 04/05/2007

The lighttpd Web Server by Bill Lubanovic

How an Accident of Hardware Design Encouraged Open Source by Mark Rosenthal
In the early 1970s, the designers at DEC made a technical decision about memory addressing that separated their computers from the mainframes of the day. That single decision led to porting woes throughout the `80s--and, so believes Mark Rosenthal, made free and open source software more possible and appealing. 02/22/2007

An Introduction to openQRM by Kris Buytaert
Virtualization saves you the headache of managing lots of separate machines. Unfortunately, lots of virtualization can give you the headache of managing lots and lots of images. The openQRM project intends to change that. Kris Buytaert demonstrates how to simplify the administration of virtual machines in a production environment. 02/08/2007

Making Apache httpd Logs More Useful by Rich Bowen
Apache httpd's standard text logfiles are well understood and useful, but they don't always give you enough information to troubleshoot problems. Apache 2.x provides several new modules that produce more logfile information--the number of bytes transferred, the rewrite rule matching, which requests complete and why, and the complete output of all headers. Rich Bowen explores these options. 02/01/2007

Handicapping New DNS Extensions and Applications by Cricket Liu
