To monitor Tomcat with Munin 2.0 on Debian GNU/Linux (tested on Debian Squeeze with Tomcat6 and Debian Backports), you need the following steps. First, you need to install package tomcat6-admin which enables the Tomcat Manager app we will be using. # apt-get install tomcat6-admin Next, create a user with a manager role in Tomcat, editing […]
Why re-invent the wheel? This post gives ample details: http://www.cyberciti.biz/faq/find-linux-distribution-name-version-number/ cat /etc/*-release o lsb_release -a
The documentation to install BigBlueButton 0.64 on CentOS (and on most other distributions) is really excellent. However, I found that CentOS 5.5 had not been documented yet, so I tried it and run into a few problems. I explain below how to get it all sorted out. I installed CentOS5.5 from a DVD in “server” […]
BeezNest is the proud provider of the hardware and systems architecture running the main server for Mantis, the missing link between multi-species full genome comparisons and functional analysis. In February 2008, Raphaël Helaers, main developer of Mantis, working at the Université Libre de Bruxelles, and fellow student in my computer sciences studies, asked us if […]
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 […]

I can’t resist posting a link to this blog post 🙂 Takes around 1 minute to read it all… Great effort from the author. Comparative installation of simple cards game under Ubuntu and under Windows.
On Linux systems, there used to be a mildly complicated but tedious way to allow you to SSH another computer using your public key, which involved finding and copying your public key on the other host, then connecting to the host and putting this key into ~/.ssh/authorized_keys. Now there is a much simpler way to […]
Basically, I’m not going to write all this again, but this is one more of these ugly things Microsoft does that makes me sick about them. I hope we get rid of them in the next 10 years, because obviously there’s something really wrong happening every time they’re involved in progress… This one is about […]
There is an interesting article (with plenty of links, but I haven’t investigated it fully so I don’t know about the real sources of all this – probably not much usable legally) on “Boycott Novell”, a website apparently talking about the underground conspiracies of the mighty against Linux. http://boycottnovell.com.nyud.net:8080/2009/01/30/microsoft-intel-anti-linux/ I thought it would be nice […]
