In recent years, the Chamilo LMS software we develop has grown in size, to something that many people might consider unreasonable (to some extent, we do too). This article explains why the Chamilo package for Chamilo 1.11.8 weighs 1100MB (yeah, 1.1GB!) or, in its compressed form, about 285MB. We’ve heard comments of many people about […]
Since mid-2018, Chamilo is supported by all 3 major auto-installer platforms: Softaculous, Fantastico and Installatron, making it easier than ever to install on your own hosted server equiped with CPanel or anything similar. Chamilo has been growing faster and faster and has reached 20M users in August 2018. Since a few years back, Softaculous and […]
If you wanted to find a good way to record good quality audio and decided to buy a Behringer C-1U (U meaning USB connector), then connected it on your Ubuntu (or other Linux distribution) only to find that the sound recording level was so low you could barely hear it, then you’re almost like me.

The default installation of Varnish 3 on Debian-based system (including Ubuntu) will set a default timeout for sending files to users (i.e. for users files download) to 60 seconds. To change this limit, it is necessary to update your default Varnish configuration, in /etc/default/varnish. For example, if you have something like this: DAEMON_OPTS=”-a :80 […]
This must appear in one opportunity in 1000, but it happened to me, so I bet it might have just happened to you… Munin is great, Nginx is great, and SSL is great, but when you mix all of them together, you might get some frustrating behaviour. If you don’t know it already, you can […]
In Ubuntu, the shipped Firefox 15 comes with the new embedded HTML5 PDF reader disabled. It is easy to enable though. Go to “about:config”, search on “pdf” and switch the “pdfjs.disabled” entry to “false”. Restart Firefox and test it pointing to some PDF URL. In case it does not work, have a look at the […]
Munin 2.0 has been released and packaged for Debian, and even backported to Squeeze (from backports.debian.org). Even though there are still some quirks in this version (or just the Debian packaging), it is far better (more scalable, more powerful and prettier) than version 1.4. Basically, the following article should cover it all: http://munin-monitoring.org/wiki/CgiHowto2, but doesn’t […]
We are currently trying out this Fail2Ban rule on one of our server, to block simple (but very upsetting) DOS attacks on Nginx automatically (after 30 seconds). New filter in /etc/fail2ban/filter.d/nginx-dos.conf: # Fail2Ban configuration file # # Generated on Fri Jun 08 12:09:15 EST 2012 by BeezNest # # Author: Yannick Warnier # # $Revision: […]

Let’s say you got confused by a misleading fake-RAID feature on an HP Blade server and you decided to ignore that the Ubuntu installer was telling you it found 2 disks while it was supposed (if it was actual hardware RAID) to be detecting only one. And let’s say you are lucky to have 3 […]
