Tutorial I presented at Computer Security conference 2000, giving many examples of small Perl scripts that can help improve security at a site.

¿Y quién es el tal Gunnar? Administrador de sistemas en la ENEP Iztacala Si bien sé algo de programación, disto mucho de ser programador Miembro externo del DSC Administrador de sistemas desde 1993 Paranóico - La paranoia es úncamente la realidad vista a mayor resolución< ¿Y qué es Perl? Un maravilloso y últimamente muy popular lenguaje de programación de todo propósito, fácilmente extensible. El lenguaje está diseñado particularmente para buena parte de las necesidades que como administradores de sistemas podemos requerir: Procesar grandes cantidades de datos, buscar patrones en grandes cantidades de datos, manejar conexiones de red, etc. Acerca de...

Ok, the time has come. I have postponed this change too much - But finally, after three months of having hired my Dreamhost account (and stating so in this very blog), I finally made the switch from Jaws to Drupal. Now I only hope I don’t flood any planets with my RSS (I was careful to check the dates are consistent, but you never know), finish moving over my static content (I carried over about half of it already), play a bit with the theme, and… that’s it! :D Anyway, I promised my oh-so-not-generic-but-what-the-heck Jaws (0.7 at least) to Drupal...

An important note Although I am interested and work in different computer security-related projects, I am not affiliated to any kind of underground movement. I know that there are many underground groups which have made important contributions to computer security, I don’t think that attacking from the shadows to vulnerabilities is not the way to go - The correct way is, instead, to raise conciousness in users, administrators and programmers on how things should be done. To whoever can contribute in further ways, with their own research and development, please go ahead. But everything, everything in an open and public...

Dato complains that converting changelogs to be UTF8-clean is not always as simple as running iconv - One of the reasons that took me so long to migrate my blog is that, due to having migrated (at different points in time) my previous CMS (Jaws 0.4->0.5->0.7), its underlying database (MySQL 3.4 -> 4.0 -> 5.0 IIRC), the distribution (Debian Woody -> Sarge -> Etch+backports), several reinstalls and all… Well, I had a completely mixed-up database, with some tables in UTF, some tables in latin1, some tables with mixed rows, some tables that for some strange reason had double-mixed rows (that...

I have given this talk on a number of places. It answers a couple of very important questions, that for many people seem to be obvious: What is Free Software? What lies behind our movement? What implications does it have? Of course, I try to give it a different emphasis, ellaborating on Free Knowledge, on software being an expression of science.<ul> Magicpoint sources for English version English presentation (exported to PDF) LaTeX Beamer sources for Spanish presentation Spanish presentation (exported to PDF) </ul> Attachments que_es_soft_libre.pdf (254 KB) que_es_soft_libre.tex (10 KB) what_is_free_software.mgp (9 KB) what_is_free_software.pdf (18 KB) Comments Edgar Casanova Cardoz...

Tutorial (not completely finished) I gave together with Rodrigo Galladro at Congreso Nacional de Software Libre (CONSOL 2002). There are many aspects in this tutorial that are just outlined, but I hope you find it useful. You can grab the source LyX document; it is available also translated to HTML and as a PDF document. As a complement, you might be interested also in the advanced Bash tutorial outline I prepared for a talk in late 2007; it is based on Octavio Ruiz (Tacvbo)’s tutorial. It only mentions the points I went over, but still, it can be a useful...
