Back from Argentina, back from DebConf. As always, the ~3 weeks I spent there were really great, in as many fronts as I can imagine or describe. But I won’t go into that now - For the purposes of this posting, the single thing that I got out of DebConf was looking with envy at all the people that had something that used to be called a sub-notebook some time ago, and now morphed into the more modern(?) name netbook. Several people were seen with their tiny Asus Eee machines, of various models. And I definitively decided I want one...

Ruby on Rails has become a very popular framework for Web-based applications. And, even though Rails itself is neatly packaged and integrated in Debian, supporting Rails applications (specially in a large-scale provider) can prove rather difficult. Besides the core application, we face problems such as handling plugins, concurrent versions, and the like. In this BoF session we discussed the different problems we face, looking towards adequate solutions. This talk was presented at DebConf 8, Mar del Plata, Argentina.

Several weeks ago, the people in charge of maintaining the Windows machines in my institute were desperate because of a series of virus outbreaks - Specially, as expected, in the public lab - but the whole network smell virulent. After seeing their desperation, I asked Rolman to help me come up with a solution. He suggested me to try replacing the Windows workstations by substituting local installations by a server having several virtual machines, all regenerated from a clean image every day, and exporting rdesktop sessions. He suggested using Xen for this, as it is the virtualization/paravirtualization solution until now...

Last week (July 7-13) was basically hell on Earth, for me and for the group that somehow got the name Cabras locas, of which I am part since I joined the National Pedagogical University, where I worked full-time 2003-2005. It was, yes, the first of my officially three weeks of Summer holiday at IIEc-UNAM, so no problems here. So, why hell on Earth? Because we were in charge basically of anything related with information flow, retrieval and manipulation at the 11th International Congress on Mathematical Education, in Monterrey. What we thought would basically be one or two days of hard...

Cruzando por esa reja, puedes subir el cerro...

Via Planetalinux.mx, I read this post by César Espino refering to Wordle. Quoting from Wordle’s main page: Wordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends. I could not resist it. I even went to a computer with a...

Firefox 3 allowed me to grant an exception on a self-signed SSL certificate for penta.debconf.org. The connection is crypted… But it seems Firefox does not realize it Attachments (27 KB) Comments Anonymous 2008-06-26 00:15:13 True, “Not encrypted” is True, “Not encrypted” is wrong, and “partially encrypted” would better describe the connection. But because the browser gets the images/css through a plaintext link, a lot of information can/will leak: the adress of the https page will be available in the clear (broweser submits it in the referer field) if the site encodes login&passwd in the URL (..?id=123&pass=456), this infocmation is available...
