writes "From the PLplot development team is the announcement of their 10,000th commit:
PLplot is a cross-platform software package for creating scientific plots that has been in continuous development since its inception 17 years ago. On May 23, 2009 the PLplot developers quietly celebrated our ten thousandth commit since our initial software repository was populated back in May 1992.
This longevity puts PLplot in some select company amongst open-source software projects. We may even be unique within this group because all PLplot development has been done by volunteers in their spare time.
The enthusiasm for PLplot development continues; we have averaged more than 100 commits per month over the last year which is double our 17-year average, and we are looking forward to the celebration of our next ten thousand commits!"Link to Original Source
