Thanks for asking, it's fun to answer, plus the other answers are a treasure trove!

For me it currently is archery, underwater hockey, running, volunteering (as swimming instructor), keeping a (planted, tropical) fish tank, learning a new language (a local Filipino dialect), electronics (home automation).

In the (in some cases distant) past (yet could come make a come back): drums, guitar, drawing, writing, photography, origami, snowboarding, reading.

I work as a(n independent) software dev by day. So programming is my job, but it is also my all time (well, since 8) favourite hobby.
