GNU Tools Cauldron 2025

Measuring the health of the GCC community
2025-09-26 , Auditorium B032 (80)

In this short talk, I look at how data mining of repository activity and mailing lists can give insight to the health of a community project. The talk offers no prescriptions, its purpose is to share techniques that may be useful to the community.


All the interactions of an open source project are publicly visible. This includes commits to repositories, activity on bug trackers and interactions on mailing lists. In this talk I will show how this data can be mined to measure the health of community. Which backends are healthy, and which are languishing, how large are the groups maintaining different parts of the project. We can even start to consider factors such as how inclusive our community is.
