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 […]
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 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 […]
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 […]
In case, like me, you use SimpleScreenRecorder on Ubuntu to do screencasts, you might be missing something: the ability to embed your webcam’s feed *inside* the screencast (like this little capture on the right side which shows how amazed I am). Well, there’s a simple, command-line based solution to that, as explained by Maarten Baert, […]
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 […]
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 […]
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 […]
Due to a licensing issue, the PHP bindings for Xapian were removed from Debian Squeeze. See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513796 for more information about this. Though, it is not really hard to build your own package from source. Here is how: sudo apt-get build-dep xapian-bindings sudo apt-get install php5-dev php5-cli apt-get source xapian-bindings cd xapian-bindings-1.2.* rm debian/control env […]
Many new videoconference systems nowadays are Flash-based. Of course, the main input for them is some sort of video device (e.g. a webcam). Under Linux, the framework responsible for this is Video4Linux (V4L), of which version 2 (aka V4L2) is current. That means that most recent webcams drivers are supported only by V4L2. Alas, some […]
This command is to be improved progressively… sudo apt-get install apache2 libapache2-mod-php5 mysql-server mysql-client php5-mysql php5-xcache php5-gd php5-xdebug screen phpmyadmin php5-imagick mercurial git php-pear php5-dev
Let’s say you want to install Chamilo on your netbook for a demo… Because Apache uses a lot of memory (and so does MySQL), it is generally considered a good practice to try and use something a bit lighter for your web server This procedure might also work, with a few minor alterations, for OLPC’s […]
