Over 30 years of FreeBSD development activity, packaged for R.
This dataset covers two aspects of the FreeBSD project:
- Git commit history (1993-2026) — every commit, every author, extracted from the cloned repository
- Phabricator signups (2013-2026) — account registrations on the code review platform
No personal information is included. Authors are counted, not identified.
