Programmers tend to have a lot of free time. You'd be hard-pressed to find a hobby that isn't popular among programmers

[throwaway675309]

Anecdotally but I find the following hobbies weirdly overly represented in IT:

1. Micro brew or craft brewing of some kind, Or at the very least an obsession with beer

2. Swing dancing

3. Frisbee golf

4. Cooking

As an engineer myself my hobbies don't intersect unfortunately:

1. Juggling and card manipulation

2. Sparta running training

3. Piano composition

4. Aviation
