Site Notice

All content on is carefully reviewed and published with best intentions of the creator. If you nevertheless find a mistake or misconception, please contact me. Go to this page to do so.

If not stated differently, all source code posted on this site and on my github belongs to the public domain and can be used in whatever form you wish (I deliberately resist to specify a certain license, because my programs partially build on other third party software which in turn only allows usage of its components under conditions).
