PhD in electrical engineering (control theory); interested in preventing "systems" from "blowing up".

Also, I sometimes feel a vocation to point out oversimplified pseudo-truths, preferably in my own bubble.

Interests:
#floss
#sustainability
#science
#KnowledgeRepresentation
#politics
#detoxification of discourse
#humor
#python
#tootfinder

Posting mostly in German, but I try to set the appropriate language attribute for each toot.

I prefer a tent to a hotel and a handcart to a car. Mainly on foot (walking, hiking, running). No car of my own but a whole fleet of cars via car-sharing if necessary. Body and soul in public transportation. In fact, I love traveling by train.
