After not attending FOSDEM for a few years, this year I decided to attend and also give a talk about “Debian packaging for beginners”, a replay of a talk given by Gergely Nagy in Debconf11.

For a non-insider (that is, someone who is not an official Debian Developer), getting a package into the Debian distribution and, by proxy, into the Ubuntu distribution requires getting the attention of someone with sufficient interest and privilege to do the actual upload. It’s called finding a sponsor in Debian parlance, and it’s sometimes a [...]

Time for another installment of my ongoing mission to convert the world to Python 3! This time, a little Debian packaging-fu for modifying an existing Python 2 package to include support for Python 3 from the same source package

I’m a big fan of iRedMail, which is basically a packaged version of Postfix and the other bits that make Postfix cool, like Spamassassin, greylisting and an LDAP or MySql back-end. One thing I wanted with iRedMail is Mailman, my favourite mailing list server. Integrating the two can be a mission though, so here’s some [...]

This manual is to help install java (jdk) in Ubuntu / Debian Linux. Previously we discussed about how java’s installation has evolved over a period, then I promised to write an article on installing java on Linux. Yes I love Linux!

After going to the Apple Store with a friend and seeing the $300+ Apple Time Capsule I decided to see if I could do the same thing with Netatalk. Turns out I could but if you’re using Debian stable like me you need to get at netatalk 2.2.x before it’ll work with OSX Lion 10.7.x.

Now it’s possible to install a full-blown Linux operating system on the TouchPad using some of the same tools you would use to install Android. The end result is a tablet that lets you choose whether to run webOS or another operating system when you turn it on.

Recently I needed to test against an FTPS server. No big deal, I thought to myself, I’ll just set one up real quick. Boy did I end up having a hard time with that. Not because the task was actually hard but because there’s a bit of a general haziness about the whole idea of [...]

Have a look at this excellent infographic for Debian – it shows the history, release process and the different user groups.
