The illumos project has been accepted as a mentoring organization for the 2013 Google Summer of Code (this marks our third year of participation in GSoC). The illumos project is a community-driven open source operating system development project derived from the former OpenSolaris project. Google's Summer of Code program promotes student involvement in open source communities by sponsoring summer internships for students to work on projects like illumos. Members of the illumos community (including Nexenta and Joyent) support this program by offering experienced staff members willing to mentor student projects.

If you might like to apply for one of these internships, or just want to learn more about our involvement in this program, please see the illumos GSoC page. OpenIndiana is also participating, under the illumos umbrella.
