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).

Today we release Chamilo 1.9.4, with a number of notable improvements in speed, usability and features, but you know... that's nothing compared to what we're preparing for version 1.10. We've got a pocket full of kryptonite ready to blow your eyes out this year, but let's focus on 1.9.4 for now.
