I like to work hearing music, especially classic music. I also like Radio Clásica, the classical music radio of the Spanish public radio. In rhythmbox it is easy to enter a new radio, just entering the URL of the radio stream in the "Properties" field of the radio.

The problem is 1) that some radios like Radio Clasica change this URL often, 2) increasingly the web pages of the radios where the stream is included use javascript and the stream url cannot be seen directly in the html source of the page.

We study this question in the recent paper “Gender Peer Effects in School,a Birth Cohort Approach” (Ciccone i García-Fontes, 2014). Our main result shows a positive and statistically significant gender peer effect of the proportion of girls on the academic results of boys, and positive but not significant on girls.

I have a couple of Drupal 6 sites using the Webfm module (https://drupal.org/project/webfm). This module was never migrated to Drupal 7 because in this last version of Drupal the file API changed completely, and the module would have to have been rewritten completely, and nobody did it.

Since about a year ago I've lost my open IP in the University network and they forced me to move behind a VPN, with a lot of issues on how to maintain my workflow. But one of the most annoying things of this is that even the most basic things like using ssh or sftp may have new issues that are very hard to debug and for which I don't have any support whatsoever by the IT support staff.

My daughter asked me recently to convert an audio file that a classmate of hers had created with an Ipad. It was a recording of a class. I looked around for converters and was pointed to Audacity, but it didn't work (it asked me to upload it as raw data, but once uploaded there was no reproducible audio). Other solutions such as "sox" where failing saying that it could not decode the source.

Reading further I seem to have understood that there is still no codec for Linux. I also looked to some free solutions in Windows and I found some, tried one and was also failing.

During the last decades in all developed countries new industrial firms have appeared that combine manufacturing activity with the services needed. Instead of traditional resources, this new industry is based on the intensive use of technological knowledge and the generation of value added through the design and the improvement of distribution channels and commercialization.

BondsIn recent months we have heard that some countries such as Ireland, Portugal and Spain, but also in a lesser way Italy or Belgium, are having trouble in issuing their debt because there is a lot of speculation and betting against them. This has happened in the past in other regions of the world such as Latin America or Southeast Asia.

It seems that talk has been started around the unification of packaging systems for various Linux distributions. There are currently different systems. Maybe the main ones are the Debian system (files with  .deb extension being used among others by Debian, Ubuntu or Mint) and the RPM system (with .rpm extension, being used by RedHat, Fedora, OpenSuse and others), but there are more, for instance the  Pacman system used by Arch Linux.

This last year I started to collaborate more with the local Catalan Ubuntu team. These are teams formed in different parts of the world that collaborate with the Ubuntu project. The Catalan LOCO team is special because it is not associated to a particular state but to the Catalan language and its variants which spread across different states.


The following steps have allowed me to configure the UPF digital card and the card reader.
