I am also Roman Catholic and very happy about that.

I am also on Facebook, not very hard to find, and on LinkedIn (but just for work stuff). Currently I am on Twitter, but considering deleting it, I guess after I get more comfortable here.


In the past, I was more "cypherpunk" than now. I got involved in scraping/archiving Pirate Bay, I got involved in bitcoin development and tooling around that (at one point in 2012, I owned about 30000 BTC, lol).

Nowadays I am not.
