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 […]

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 […]
For those of you pushing your MySQL instances to higher levels, you’ll have realized at some point that all InnoDB tables share their indexing space into a single file (ibdata1, usually). This has several very bad outcomes: the ibdata1 file becomes huge after some time (we’ve seen it pass the 8GB bar) starting the MySQL […]
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, […]
