Welcome to my digital garden. It is freshly planted and still needs some time to grow. It is a kind of personal but publicly accessible library in which I archive information that I deem useful. Of course, you are invited to stroll around the pages, but be warned: it is constantly under construction and thus some paths may change over time. Oh, and the language switches between English and German, depending on the topic. With all that out of the way, below you find some topics out of my field of interests.
