I'm a CS student at master level. I also study Game Studies, and Psychology.

I'm learning:

• 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)
