@mozzadrella The active open source project that I was able to locate was youtube-dl, an open source project from developer Ricardo Garcia. This project was found via a review of weekly trending repositories through GitHub Explore, its presence no doubt influenced by a massive star rating and number of forks (see below)
Live since 2008, activity has stayed consistent since it’s peak in mid-2015 with more than 16,000 lifetime commits and 622 lifetime contributors. (see below)
While lifetime commits and contributors are of interest, they do not demonstrate current activity; for that we can instead look to recent insights. Over the past year youtube-dl has seen an average of approximately 20 commits per week, with many weeks well exceeding that average (see below)
Looking at the past month, we can see that this strong project activity has continued through the many active and closed issues, as well as nearly 100 commits from 8 different authors.
The insights provided through GitHub are incredibly valuable to assessment of group work, providing a quick-and-easy snapshot of not only who is committing but when, what and how often. This data takes so much of the guess work out of the evaluation process, allowing educators to not only make more valid and reliable assessments but to provide identify (and provide support to) students who may need a push in the right direction.
