Check out Facebook’s worldwide coding competition:
The 2011 Facebook Hacker Cup is the first annual Facebook programming contest where hackers compete against each other for fame, fortune, glory and a shot at the coveted Hacker Cup. […] Many will enter, but only one will claim title as champion and take home the $5,000 USD cash prize and be immortalized on the Hacker Cup.
Registration opens on December 20th 2010.
On a side note, I love that poster design. :)
