We provide a wide range of competencies due to a lot of experiences in setting up IT systems and developing software. The observation and the active participation in the free and open source movement brought a lot of possibilities to study operating systems, software development and setup of whole IT environments based on free tools.

The most exciting things in the last two decades were the development of the Linux kernel and the GNU operating system and the growth of the free and open source movement in parallel. The world got new operating systems presented which can be used in daily life and even in productive environments. Additionally a large set of comprehensive, high quality software packages were developed over the last years for free use.
