If you design your icons in SVG with Inkscape and wonder how to quickly make an “inactive” icon in grayscale, here’s a quick fix (at least for Linux users): inkscape -f teacher_na.svg –verb EditSelectAll –verb org.inkscape.color.desaturate.noprefs –verb FileSave –verb FileQuit This will edit your file in-place (so you need to take a copy first) and […]
For those of you looking for a guide to install Chamilo 1.10 on CentOS, have a look here for a great community contribution by Arun Pyasi: http://linoxide.com/tools/setup-chamilo-e-learning-system-ubuntu-15-04-centos-7
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 […]
If you’re ever stuck with broken tables in MySQL or MariaDB and you don’t know which, you can use the mysqlcheck command to repair them all, one by one (you can also use the –optimize argument). mysqlcheck -u root -p –auto-repair –all-databases
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 […]
If you’ve been using or maintaining support for NuSOAP lately, you’ve certainly realized that it does not work properly anymore. This is because NuSOAP isn’t maintained anymore, so a lot of things are bound to stop working as PHP versions drop support (or tolerance) for specific code. Well apparently, there are fixes around. Notably, for […]
When you play a lot with branches and kind of keep track of what should or shouldn’t be merged between them, there’s kind of a magical set of commands to force-overwrite your code with a specific branch: git fetch –all git reset –hard origin/master Make sure you have commited all your changes to some branch […]
If you have bought an HP LaserJet 100 printer and have it connected on the network, but somehow fail to scan from it, here’s how: sudo apt-get install hplip (chances are you already did that, but in the worst case this will do nothing) sudo hp-setup (this launches a new window) search network (if you […]
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 […]
