In time of COVID-19, we are (relatively obviously) inundated with calls and e-mails from people inquiring not only for Chamilo hosting (and other) services, but also for asynchronous communications for students and teachers alike. Suffice to say that there are already several options to do that in Chamilo: a global chat box allows you to […]
On the line of my latest post about Linagora, a European data researcher recently published the results of a study concluding in that the European Community is saving 450 billion euros per year thanks to Open Source software. In the same orientation, the APRIL (French Association for digital freedom) published a study reporting the substantial […]
Today I just saw one of the most beautiful examples of what our efforts (as a community of free software, standards, formats and knowledge evangelists) are all leading to. In short, I’m talking about the Wikipedia page in English for the OGG standard, which I’m publishing a capture of below. “So, what’s so special?” you […]
The recommended filesystem for Squid on OpenSolaris is ZFS: http://wiki.squid-cache.org/BestOsForSquid It is also recommended to disable the atime property on the filesystem holding the cache, and you may want to avoid using any type of RAID. To achieve this on Nexenta (or OpenSolaris, whatever), first create the ZFS filesystem: # zfs create -o atime=off -o […]
Disclaimer: this article does not pretend to be a complete picture of using swap on UNIX. Most of the time, recent GNU/Linux distributions insist on creating a swap area. Swap is generally used to temporarily store memory used by running(/sleeping) applications, but might as well be used to store a copy of RAM to disk […]
GNU/Linux supports swapping to a file on any filesystem, with reasonable performance impact since kernel 2.4. This might be useful whenever needing a temporary increase in available memory, I’m writing this article with that goal in mind. Create a zero-filled regular file (following example would create a 1024x1M=1G swap size): dd if=/dev/zero of=/.swapfile bs=1024 count=1M […]
I had a problem with a very old Compaq PC not detecting the keyboard anymore. I used the PC as a local server, not a real problem, except that the BIOS didn’t allow the PC to boot when the keyboard was not plugged in. One solution there might have been to use some USB keyboard […]
If you are a free software activist like me and want people you expose free software to in conference, large meetings and other gatherings like that (preferably developer-oriented) to understand what the value of free software is, here is a game proposal for you to try out (please report on the success of this method […]
There’s an interesting document from Pentaho about Open Source Business Model. I like the link at the end.
Herodoto is joining the Dokeos development team as an independent (and distant) developer today. He will be in charge of integrating the wiki tool, under my coaching. The wiki was previously a separate plugin in Dokeos, so we hope it will be stabilised and integrated in time for 1.8.6 at the beginning of October. Herodoto […]
Following an internal meeting at BeezNest, we decided to officially provide services for OpenERP before the end of the year, through an official partnership with Tiny SPRL, the company behind the product. We found a lot of little bugs and usability problems, and submitted our first bug report following the little comment by Stéphane Wirtel, […]
Wow… this is great news for us. Mike Melanson, the developer of the Linux version of the Flash plugin, just announced on his blog that Flash plugin 10 beta 2 will start supporting V4L2! For Dokeos, this means that we will now be able to use the video recording of our little webcams directly from […]
