Many new videoconference systems nowadays are Flash-based. Of course, the main input for them is some sort of video device (e.g. a webcam). Under Linux, the framework responsible for this is Video4Linux (V4L), of which version 2 (aka V4L2) is current. That means that most recent webcams drivers are supported only by V4L2. Alas, some proprietary editors (of which Skype and Adobe with Flash) still only support V4L1.

This command is to be improved progressively... sudo apt-get install apache2 libapache2-mod-php5 mysql-server mysql-client php5-mysql php5-xcache php5-gd php5-xdebug screen phpmyadmin php5-imagick mercurial git php-pear php5-dev

Let's say you want to install Chamilo on your netbook for a demo... Because Apache uses a lot of memory (and so does MySQL), it is generally considered a good practice to try and use something a bit lighter for your web server This procedure might also work, with a few minor alterations, for OLPC's XO laptops.

I will be presenting Chamilo and our intention to make a Chamilo package for Ubuntu this year at the Ubuntu Developers Summit in Brussels, on Friday 14th of May (at the beginning of the afternoon).

After Ubuntu's decision to default to OpenJDK for 10.04 (which is a good decision, IMHO), Sun's (but is it still Sun, or Oracle?) JAVA somewhat "disappeared" from Ubuntu (multiverse). That being said, some people may still need features only available in Sun's JRE/JDK, which might not yet have been Freed. Actually, Ubuntu is still shipping it, but in its "partner" section.

This one is tricky... (and not so practical just yet) So let's say you have a 120 pages document, written using MS-Word, and which is understood pretty well by OpenOffice.org Writer (v2). Now let's say your document is a technical document and, as such, it is half-full of screenshots taken from a software interface (in this case Dokeos) directly into the language of the document. See what I mean? Now, let's say this document is in French and you want to translate it to English (or Spanish, the problem is exactly the same).

Due to a few missing bits in the DOKUDA video-editing team, I had to turn my MacBookPro on Ubuntu 8.10 into a FireWire (ieee1394) video recording device, through the reading of the DV tapes in a Panasonic PV-GS9 video recording camera. Surprisingly, this did not work out of the box. It should have worked with a simple "dvgrab", but when connecting the camera to the FW port, it seemed to remain undetected. After a few trials (including a reboot), I realized the FireWire module (raw1394) should be loaded into the operating system.

This is a quick report on my first trial as a local group coach for the PHP TestFest 2009 for the PHP Perú group. Assistance: 20 people (all more or less PHP developers, some very fresh) Preparation time: about 6 hours of readings, downloading, slides preparation, etc Teaching time: 2 x 1/2h.

Most of you playing with a laptop or a PC with a beamer will have noticed that when you change the resolution of your screen, applying the changes suddendly blocks your screen in a high frequency that prevents you from changing back to normal. Didier Misson (one of my fellow BxLUGers) wrote an article about that desktop resolution bug (in French) and how to fix it changing the /home/[user]/.config/monitors.xml file. Might help...
