Chamilo LMS 1.9.8 comes with an OpenMeetings plugin. This means that you can organize OpenMeetings videoconference rooms directly from your Chamilo courses. Now this setup requires a few essential things.

If you're in a hurry/on speed, know this:

• this procedure is slightly more difficult (so longer) than installing the charm on Amazon
• you can skip directly to "Installing Juju"
• if you already have juju installed, you can skip to the last 2 lines of the "Installing juju" section
• if you already have juju-docean installed and configured, you can skip directly to "Provisioning VMs"
• otherwise, just continue reading, it's worth a few minutes...

This tutorial regroups a lot of advanced notions, so if you want to know more about one of the follo

In a growing world with growing education needs, one would think that systems like Chamilo or Moodle would have a continuous growth ensured, year after year. Well, this is certainly true for Chamilo LMS (for now), as it is apparently gaining about 100,000 new users per month (average over the last 12 months), but I am a little in shock at how Moodle is (since a year or so) loosing a considerable amount of sites and users over the last 12 months.

Note: this article was originally written for Chamilo 1.9 but it is also valid for all versions 1.10 and 1.11. We seldom receive a request from users of Chamilo LMS saying their sessions are cut in the middle of their activity. And sure, it might so happen that you are in the middle of the redaction of a very large answer to an open question, or diserting on how the course is going to help you in the forum. And we get that it's super-frustrating to click "submit" and then get an error page.

This Sunday 15th of June 2014, we will be releasing version 1.9.8 of Chamilo LMS. This will be the last big version of the 1.9 branch (version 1.9.0 was released in August of 2012, about 2 years ago).

Sometimes you find a perl in some code and it might take you a while to understand. In the sessions management code of Chamilo, I found this the other day, then decided to leave it for later because I was in a hurry. Then today, I found it again, and again...

Supposedly, Gallery 2 has a process to clean this table periodically (through Cron, which you should always configure), but apparently sometimes this doesn't get to execute correctly. As a result, the rest of the cleanup will happen but this stable might not get cleaned, leading you to millions of rows of purely useless years-old cache junk. Fix it manually by issuing a "TRUNCATE [prefix]_ImageBlockCacheMap;" in your database, or install a more recent version of Gallery, or something like that, but make sure you always keep an eye on its size.

Just in case you ever fall on that issue, please note that there is an option to enable as platform admin in Chamilo LMS 1.9 that allows for the use of iframe in the online editor area. I leave a link to the related task in Spanish in our tracking system, in case you would need it. https://support.chamilo.org/issues/6992  

Just in case you would be in this situation (and given the fact I couldn't find online information about it), if you are ever installing the mysql2 gem on a Debian Wheezy system with MariaDB 10 (I would guess a rather rare situation), you might get this error:

# gem install mysql2 -v=0.3.11
Building native extensions. This could take a while...
ERROR: Error installing mysql2:
