This is Matthias Kirschner's private blog. In my day job, I am the president of the Free Software Foundation Europe (FSFE). I have been involved in Free Software since the late 90ies, so many of the posts here are about Free Software (also called Open Source Software). Recently, in my spare time, I have written the book "Ada & Zangemann - A Tale of Software, Skateboards, and Raspberry Ice Cream", which is available at publishers in English and in German and translated into Arabic and Ukrainian.
