I currently work for SGI (perhaps better known by its previous name: Silicon Graphics) where I provide technical support for SGI's flavor of UNIX (IRIX), and also for Linux. This section contains some links to work-related stuff, including my resume, of course.

Here is my (more or less) current resume, which is also available in ASCII, PDF, ODF Text, MS Word 2000/XP and MS Word 2007/2010 XML formats.
I put this together while I was preparing for my own Red Hat Certified Engineer (RHCE) test. As you can imagine, it doesn't contain any information whatsoever about the actual questions that were asked during the test (that would be a breach of the non-disclosure agreement I had to sign), but rather a nice collection of tips that you should know about before taking the test. Of course, it can also be used as a simple list of tidbits of information on Red Hat Linux. One of these days I may find the time to update it to the newer releases of the OS. The document was originally published on the LinuxNovice website.
Resources to guide you through the world of Debian GNU/Linux, perhaps the most important Linux distribution designed and developed solely by a global community of volunteers.
Links to resources on OpenBSD, the secure BSD operating system.
A collection of resources on shell scripting.
Links to resources on LaTeX, the software system for document preparation.
While full of flaws and way too manual for my liking, the reality is that RPM has become the de facto standard for packaging applications in the Linux world.
Resources with information for anybody interested in the Python programming language: books, sites, documentation, etc. Python is a very easy, clean and yet powerful programming language that I would definitely recommend to anyone interested in learning the basics of programming.
List of computer-related classes freely available online that I am following in order to learn more about certain topics.
As the name itself indicates, a self-guided course around the topic of systems analysis, including introduction to basic concepts, algorithms, data structure, systems programming, C language, programming, etc.
Notes taken while studying the world of cluster computing, typically deployed in high-performance computing environments.
Self-guided studies of the Linux kernel and other OS design concepts, using mainly documentation freely available online as well as reading the source code itself.
After quite a few years working in the field, I decided to put together this handbook, hoping that it would prove a useful reference for me and others. Perhaps not very comprehensive, and definitely not very eloquent. It was conceived as a gathering of summaries and schemas, more than a lengthy explanation of the main topics about system administration. In other words, it assumes some prior knowledge, and is therefore good only as a reference.
