Aldo Cortesi's analysis of GitHub projects examines the average number of contributors, their commit responsibilities, the size of patches, and the number of files affected by these patches across over 1.5 million commits made by 20,000 contributors in 30,000 active repositories. The study provides insights through a series of graphs accompanied by commentary, highlighting the impact of language choice on project dynamics. The dataset used for this analysis is available as a PostgreSQL dump file, and Cortesi invites suggestions for further refinement or expansion, encouraging others to delve into the data.
