Hello all, when Steam first announced they'd give all present and future games free to all Mesa contributors with at least 25 commits[1], I was curious to see how many people would be affected by this choice, so I ran some statistics on the number of committers (and contributions by committer) on Mesa at the time, with the following results (for April 9, 2015):
# count: 684 # min: 1 # max: 14020 # mid: 7010.5 # range: 14019 # mean: 101.35818713450293 # stddev: 652.7501707733724 # mode(s): 1 # median: 2 # quartiles: 1 2 10 # IQR: 9 Having come across an old discussion about these stats, I decided to rerun the stats now, and the results are: # count: 736 # min: 1 # max: 14310 # mid: 7155.5 # range: 14309 # mean: 102.19701086956522 # stddev: 651.6642244733528 # mode(s): 1 # median: 3 # quartiles: 1 3 12 # IQR: 11 And I would say that this counts as an improvement: the mean number of contributions per developer has gone up, but most importantly the _median_ contribution has gone up (from 2 to 3 contributions), and ditto for the upper quartile (from 10 to 12). In some sense, the 'long tail' of contributors in Mesa has _shortened_ in these 8 months, even though the number of contribution has increased! The only problem with these numbers is actually the lack of a .mailmap to normalize contributor name/emails, which obviously skews the results a little bit towards the lower end. I don't suppose someone has a .mailmap for Mesa contributors, or is interested in creating one?
