For those developers of you wanting to do more than just develop under Linux, you'll have realized that there are many things stopping you for doing proper video tutorials as easily as you would do it with some non-free (as in freedom) software. Fear not, though, as this tutorial, written at a time between Ubuntu 14.04 and 14.10 with the Gnome Shell, will help you go through it and hopefully setup a perfect environment that you will be able to re-use anytime, anywhere (with your laptop).
For one of our developments, Julio found an interesting JQuery library which allows you to change colours on the fly, find the other colours on a colour wheel, "summing up" colours (make yellow + blue = green), etc. Find out more about the xcolor plugin.
For those of you lucky enough to have tried a fixed-width layout in Dokeos, you will probably have fallen across the horrible background-color line bug that appears just below the banner...

A few weeks ago, I explained how to change the Dokeos footer to make it "float". Today, in the context of an indirect contract with the Ministry of Education in Peru, I have to change the style a little bit more. The idea is to  have a left bar showing large tools icons in the course homepage, and  have an alternative portal homepage for users, showing an introductory screen of the main general tools. This must all work on a 800x600 screen (which is a real challenge).
