Greg DeKoenigsberg's POSSE program -- Professor's Open Source Summer Experience -- is a week-long immersion in the world of community-based open source open to any professor teaching programming.
This is a fantastic opportunity to get up to speed on open source development: working (1) at scale, on large codebases used on production systems, and (2) in community, collaborating on a global scale and leveraging the network effects of an open source community.
The application deadline for POSSE is this Friday, April 3. Red Hat is picking up all costs except for transportation -- you just have to get yourself there. Don't delay: read the wiki page and send your application!
