After a successful first try in 2005, Google’s Summer of Code has been expanded this year to cover 630 students. With Google paying $4,500 to each student and $500 per student to each mentoring company/project; that amounts to over $3m of development sponsorship.

The Open Source Development Labs, which is home to Linux creator, Linus Torvalds, and Linux maintainer Andrew Morton, has also joined the project for the first time, mentoring four students across the world.

Student from the Indian Institute of Technology, the University of Zagreb in Croatia, the University of the Philippines, and the Federal University of Pernambuco in Brazil will work on projects involving NSFx4 fault recovery, the Linux Ethernet Bridging project, SendPage enhancements, and TBC-E fair-use respectively.
