When it comes to code, Google's support has made a big difference to the Tor Project. Providing privacy and helping to circumvent censorship online is a challenge that keeps our software developers and volunteers very busy. The Google Summer of Code brings students and mentors in the open source community together to write code for three months every year. A lot of coding got done in a few months in 2009, and Tor was lucky to get a group of students who kept on working past the summer months to improve existing projects and support users. Tor also works on Libevent with Google.
