RATIONALE OpenBSD is a stable, robust and secure operating system. Systems administrators running OpenBSD tend to be also more security conscious than administrators running other operating systems. Nevertheless, patching an OpenBSD system can be a tedious process for many people. If a person manages multiple OpenBSD servers, patching each of them can be a long and repetitive task, ideal for automatization. Tepatche will periodically check the FTP site we indicate it to, and if there is a new patch to be applied, downloads, applies, builds and installs it. Tepatche mantains a small status database to know in what is the...

This talk is basically the result of mixing What is Free Software and Quality Assurance in Free Software projects, emphazising in the knowledge production aspects related to Free Software. This talk was first given at the UNAM Economical Research Institute, April 12, 2005.

SmbGate is a little program written in Perl (using the Embperl framework) that allows users to connect to their home directories in a SMB server (be it Samba running on an Unix-like environment or Windows). It implements read-only access, using a Web-based interface. Attachments SmbGate-1.0.tar_.gz (488 KB)

The Web development framework “Ruby on Rails” has gained adepts with an impressive speed. What brings this success on? Ruby is a very comfortable and expressive language, and clearly a young language. Even being quite a nontypical language at a first look -to say the least-, after not such a long time, it becomes just natural and we start wondering how we managed to go by without it. But Ruby’s comfortability is nothing but the first step towards Rails. Rails’ complete style keeps in the programmer’s mind the best way to go through the easiest path - And I mean...

Free Software has many advantages against propietary software in many areas. However, when we talk about the government, this goes soon beyond convenience - It is necessary that, if a government dependency hires or carries a given development, it should demand that the license it is made on is free and it is built over a free infrastructure. I gave this talk in Mexico city’s Government’s Encuentro de Informática de Otoño 2003, explaining the reasons for these demenads.<ul> Source Magicpoint format Converted to HTML </ul> Attachments soft_libre_gobierno.mgp (11 KB)

Perl is one of the most popular languages today. Many people, however, do not think it is a good language to do objet-oriented programming, that it is a difficult task to do it or similar things, and leve Perl for tasks that are just too simple. In this tutorial I present an introduction to object-oriented programming in general, and show how to use this technique in Perl.<ul> PDF (27 pages) Converted to HTML HTML Document sources in LyX </ul> Attachments poo_perl.html (162 KB) poo_perl.pdf (294 KB) poo_perl_lyx.tar_.gz (38 KB)

This talk was prepared for Congreso GNU/Linux 2002, prepared by GULEV in Veracruz, December 2002. Here I talk about the process leading to the creation of this new version of Perl, and the main changes we can expect for this language. I wrote the presentation in Magicpoint; you can download the source Magicpoint file, or if you prefer, open the presentation converted to HTML. Attachments perl6.tar_.gz (55 KB)

This talk is heavily based on QA in Free Software projects; it has basically been reformatted, rearranged and updated. So yes, if it sounds familiar… it is because it is so. Source LaTeX beamer presentation Converted to PDF Attachments partic_proy_sl.pdf (518 KB) partic_proy_sl.tex (36 KB)

A system I wrote while working for FES Iztacala. It helps a network administrator on his tough job relating MAC and IP addresses, generating configurations for the DHCP server and for ARP. Several years later, already working at IIIEc UNAM, I practically re-wrote it from scratch, cleaner, with an object-oriented layer, using the Template Toolkit for the presentation, and as an Apache module (with mod_perl). Both versions are useful and usable - here you have both. Both are, however, in a “snapshot” state, lacking smaller bits of functionality and documentation.
