Neckbeard, but I am unable to grow a beard.

I'm a polish software engineer by trade (and passion) working on #Ruby on Rails in a SASS. But my true heartbeat is the #foss #RetroComputing rhythm: I love my #emacs #freebsd combo. I am very much into #smallweb and all that it stands for.

I love good #SciFi but recently I've been reading good #fantasy - which is a shock to me. There are great fantasy books out there!

Piracy is the only answer to streaming services.
