Your English is wonderful; my German is limited to the first word I wrote here! I think you will find much information and many helpful people at this website. Some (but not me) are very knowledgeable about computers -- with your interest in computer science, you will be very comfortable in this group.
We look forward to your participation here -- any questions are happily accepted, we don't have all the answers but we will share our thoughts. We hope you will share with us, too.
Once again, welcome, Tobi.
