Temporal characteristics of collaboration in the Penumbra and GitHub. Comparison of GitHub and Penumbra samples on a variety of temporal metrics. The age of repository is given by the time between the first and latest commit. Panels (b-d) look at the heterogeneity of time between events. We first compare the distribution of mean interevent time to the distribution of ratios of age to number of commits, then show the distribution of index of dispersion per repository. Panels (e-f) compare how collaborative repositories actually are, or whether they are dominated by a single committer
