Estimating commit sizes efficiently [OSS 2009]
Authors: Philipp Hofmann, Dirk Riehle Abstract: The quantitative analysis of software projects can provide insights that let us better understand open source and other software development projects. An important variable used in the analysis of software projects is the amount of work being contributed, the commit size. Unfortunately, post-facto, the commit size can only be…

The sweet spot of code commenting in open source
In a large-scale study of active working open source projects we have found an average comment density of about 20% (= one comment line in five code lines). Given that much of open source remains volunteer work, we believe that a comment density of 20% represents the sweet spot of code commenting in open source…

Or, to be frank, I think if somebody talks about donating code to the community they probably don’t understand effective open…
