PhD in InfoSec, but quit academia right away. I just can't. I am into FOSS, privacy, and human rights. I work in data by day, but I'm a fulltime human rights activist and have spoken at various fora against digital dictatorship and BigTech's shitfuckery.

Outside of my activism, I enjoy walking my dog, Heidi, vegan food, gaming, socialism, programming and makeup. Hope to connect to like-minded people (or not, challenge me)

Working at front lines of the IT and having fun there. Been around the Internet since 1992 and still in awe what has become of that little baby.

Personal interests:

- Books (mostly F&SF)
- IT Security
- Computer Games & RPG
- Cooking
- Movies
- Everything that blinks, has buttons to press and looks remotely gadgetoid

Everything i write, post, tweet, blog or blurp is just my personal opinion and is not the opinion or policy of my employer, my cat or my goldfish.

I post in English and German. Will try to mark each post correctly, but errors happen. Sorry for that.

I appologize if I am not following you back. This happens as my stream is already getting more posts than I can read.
