I'm a CS student at master level. I also study Game Studies, and Psychology.
- Objective-C (I have a few hundred hours under my belt :) )
I sometimes use:
- PHP, jQuery and web development in general (for fun)
- Java (heavily used for school assignments, it was required)
- Python (used in courses where I am a TA, and required for 1 course)
I would like to learn (but lack of time):
- C (hacking, low level stuff)
