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 […]
This guide will take you through the process of installing the Chamilo e-learning portal, version 1.11.4 on a fresh Digital Ocean instance,on an Ubuntu 17.04 64bit distribution (also works with minor changes with Ubuntu 18.04) To follow this guide, you should be familiar with the notion of SSH keys and installing/configuring server software on Ubuntu […]
As a web developer configuring SSL certificates on websites you deliver, as we do, you might be faced, one day, with a small issue about configuring a 301 redirect from HTTP to HTTPS that has to be reverted. It so happens that browsers *really* take it to heart to cache an HTTP 301 (permanent redirect) […]
This article can be considered an update of our first article on installing Chamilo (on a Raspberry Pi B+). This time, we are testing it with Raspberry 3, as of the 1st of April 2017 (no joke intended). Last time, we were testing with Chamilo 1.9, which is arguably less load-intensive, considering it doesn’t include […]
Redmine is a project management system and a support ticket management system. See other articles on this blog and my video on YouTube about a previous version of Redmine for more info. At some point (and this only happened to us after years of use and more than 10.000 tickets/issues registered), you might want to […]
If you have to maintain an open source project written in PHP, like we do with Chamilo at BeezNest, you’ll have to test your software on multiple versions of PHP to make sure of how well your code is supported on these versions. Of course, being open source, you can publish it on Github and […]
In Chamilo LMS 1.9.* (meaning 1.9.0 up to 1.9.10), deleting some files from the web interface don’t always delete them on disk. While this means that, sadly, you don’t get to get space back when cleaning up your courses, you can at least recover them (or your administrator can) if you deleted them by mistake. […]
This is a short note for ourselves, but it might help others considering the (new for now) rules of Google indexing of non-mobile sites. Drupal 6 does not really provide all the stuff that would be really useful to switch the theme of your site depending on the browser being on a mobile device or […]
This command mentionned by Pete Doherty, found on in the comments of this article http://gitready.com/intermediate/2009/03/04/pick-out-individual-commits.html, is simply awesome: git log –graph –pretty=format’:%C(yellow)%h%Cblue%d%Creset %s %C(white) %an, %ar%Creset’ It will show something like this (in the terminal)
dirname(__FILE__) and __DIR__ give exactly the same result in PHP, although one (__DIR__) is evaluated at compile-time, while the other (dirname(__FILE__)) has at least part of it (the function) evaluated at execution time. Ever wondered what the difference is, in terms of efficiency, between the two? I’ve written a *very* simple script to try it […]
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 […]
This article is an extension of the previous article about storing sessions in Memcached with PHP. Using Memcached for sessions storage is generally a matter of speed (storing them in memory is faster than on disk) and of scalability (using a Memcached server allows you to have several web servers serving the same PHP application […]
