I am thinking of creating a new society at my college. I'd like to bring together some hackers; the idea is to be able to meet like-minded people. Typically, societies meet up once or twice a week.

My question: any ideas on what could be done during such a meeting (typically 1-2 hours)? Some possible things include:

- short (10min) lectures on interesting stuff

- programming competitions

- forming up into teams to work on individual projects

- ...

However, this is all still very rough. If you guys have any better/more concrete ideas, I'd be very glad to hear them!
