How can I make a little bit of money during the school year on the side?

I need to make a little bit of money. I don’t require a lot of money but I need a little bit coming in during the school year. Unfortunately, since it’s during school I won’t have a lot of time.

Do any of you here at fluther have any ideas as to how I can make a little bit of money online without a huge time commitment? I only have programming skills, which don’t lend themselves to short projects very easily, so it’d be nice to have something not difficult or with too many prerequisites.

Thanks!
