Perl modules are very well organized in CPAN: They can usually be easily found and, thanks to tools such as the CPAN shell, they are easy to install and update even by novice users. However, when people start using Perl systems (as opposed to using Perl for writing such systems), asking them to take care of the dependencies or having them worry about different distribution architectures is a pain that should be spared from them. In my talk, I will describe how Debian (and other Free Software distributions) addresses this problem by packaging a large subset of the CPAN archive,...

This is only a first approach, and not a presentation I’d like to regard to as finished. I was asked to present this as part of a panel in Linux World Mexico Conference & Expo 2008: A brief introduction to Free Software licensing schemes.

I just spent the productive part of the last couple of days going over several alternatives, as I didn’t want to do the most obvious thing. But I ended up doing it. I think I did it carefully… And in a restricted system. Still, having a Web-facing script that executes a password-changing script running with Sudo-granted privileges… No matter how much correctness and sanity checking it involves… Makes me feel dirty.

I sent this short article for publication at the Software Gurú magazine. It describes the work we do at Debian’s pkg-perl group. This is based on my slightly earlier talk Integrating Perl in a wider distribution: The Debian pkg-perl group, shortened and translated to Spanish. It was published on the Software Gurú August-October 2008 magazine - You can get the printed version of this text as well.

I presented this talk at the II Computer Systems Engineering Conference at Nuevo León Technological Institute. Here I review general security concepts, explaining to a non-expert audience various important factors that as security experts -and as conscious users in general- we must take into account.

Are you looking for an easy to implement backup solution that allows you to have incremental backups, with low resources consumption, and allowing for immediate retrieval of your data? Rsync and the basic characteristics of any Unix filesystem can be your greatest allies. I prepared this talk for the Admin-UNAM December 2005 seminary, organized by the Computer Security Department, DGSCA, UNAM.

I wrote my final paper for graduation on implementing a generic connection wrapper that can be extended to understand and protect specific protocols. I presented this project at YAPC::NA 2001, and published a short article on Usenix’s ;login: magazine (published in the June 2002 number).

This talk was prepared for IV National Free Software Conference in Universidad Mayor, Real y Pontificia de San Francisco Xavier de Chuquisaca, Sucre, Bolivia. This is more or less the second part for my Network security talk, bringing down to earth some of the concepts to more concrete solutions (although still fairly generic). I presented it in 2005 for UNAM’s Computer Security Department’s Admin-unam internal seminar; I re-wrote it as a full-text article, also available here. Magicpoint presentation converted to HTML Full text article in PDF, with the same general structure as the presentation, but much easier to follow Magicpoint...

I presented this tutorial at Computer Security DGSCA/UNAM 2003 Conference. I talk about the basic characteristics for an Ethernet network, what is sniffing, some sniffers useful for a network administrator, and some advices for protecting against unauthorized sniffers in our network.

This talk was prepared for the National Free Software Conference CONSOL 2003 and for Computer Security DGSCA/UNAM 2003 Conference. I analize the main ideas that were used for designing Multics, which of those ideas were adapted for the Unix model, which main shortcomings the traditional Unix model has, and what ideas have evolved to make Unix better.
