Definitions

The co-developers are developers who have modified the same file in an OSS project. The hop is the number of co-authors between two developers. Assume developers X and Y are co-authors, and developers Y and Z are co-authors, but developers X and Z are not co-authors. In this case, the hop between X and Y is 1, and the hop between X and Z is 2.

Findings

• There are about 90,000 developers in the database and 95% of them are connected with a few hops.
