FreeBSD is an open source Unix operating system with a long history and large base of developers and users.

FreeBSD is a mature and relatively centralized open source organization. We have over 350 committers with write access to the revision control repository, an elected 'core team' of project leaders, and various committees for the release engineering, security officer, third-party package management, and other roles.

We take mentoring seriously for all new FreeBSD developers and we provide the support and infrastructure necessary to ensure our students can succeed.
