One possible annoying element of Chamilo is it can only answer to one address at a time. This simply comes from a very old codebase and the fact that, at some point in the past, it wasn’t that easy to get the address from the URL or the HTTP headers in a reliable way. Nowadays, […]
With the Command Line Interpreter for PHP (most of the time called php-cli or php5-cli), you can check if one single file contains syntax errors by simply calling php5 -l file.php The problem with that is, if you have many files to check, on the command line you might easily spend your time typing filenames. […]
(Read the update below before starting to copy-paste) To install Xhprof on PHP5.4 on Ubuntu (assuming you’ve already got PHP5.4 from Andrej or somewhere safe) in order to measure the load of Chamilo 1.10 dev (you need to have a mercurial clone, otherwise the “tests” directory will not exist), follow this procedure (all lines prefixed […]
If you ever want to install the amazing multiplayer SoulFu medieval-fantasy game from Aaron Bishop (up to 4 players with joysticks & keyboard on a single computer) on your Ubuntu 12.04 (Precise) 64bit, follow the howto below. The most problematic point is that it depends on libjpeg62 compiled in a 32bit version. To install this […]
This article is co-authored by Jérôme Warnier, from work mostly done by him with my occasional support. Kudos go to him. We couldn’t find any valuable manual to install Redmine 2.1 on Debian Squeeze, and we sure met a lot of resistance along the way, so we came up with the following step-by-step guide… Sources […]
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 […]
The written proceedings of the 2011’s International Conference on e-Learning in Serbia caught my eye with an article called “HYBRID MODEL FOR E-LEARNING QUALITY EVALUATION” by Suzana Savić, Miomir Stanković and Goran Janaćković, not actually for the hybrid model (although it has its merits), but mainly for listing projects analysing different aspects of e-learning quality […]
Tagalog is the national language of Philippines and, although it’s now written mainly in latin fonts (as Wikipedia reports), it can also be found written using the Baybayin script.Well, somehow, it seems difficult to find any relevant information on how to display Baybayin fonts in your browser in Ubuntu. After a little bit of common […]
A really good guide on branching is available here: http://stevelosh.com/blog/2009/08/a-guide-to-branching-in-mercurial/ In my case, I wanted to branch a previous version of my code to launch a parallel branch for bug-fixing of the previous release. I used the Chamilo code repository on google code. I already had a local copy (in /var/www/chamilo), so what I did […]
If you’ve been into website development, and in particular website optimization, you probably have stumbled upon that question at least once: what HTTP headers do the different browsers send when the user presses F5 or (even better) CTRL+F5, to make the web server bypass the cache system? Well, the user “some” on Stackoverflow answered that […]
This is the life-saver cheatsheet you need if you’re ever going to want to understand complex rewrite rules like the ones generated by the Boost module in Drupal: http://www.askapache.com/htaccess/mod_rewrite-variables-cheatsheet.html In particular, in RewriteRule .* – [S=5], the [S=5] rule means “skip the next 5 lines”. It can represent a considerable efficiency boost! Same thing can […]
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 […]
