For about a month, I’ve been improving a set of scirpts to calculate statistics on the Qt Project. What I wanted to know, at first, was how well I was doing, how much I was contributing. Another question I had in mind and I know many others did too was “how much is the Qt Project dependent on Nokia?”
First it started with a simple “|wc -l” depending on whose statistics I wanted to get. This week, I decided to make graphs, so I spent a great deal of time learning gnuplot instead of doing other work. I’ll blog about the script itself on my next blog.
The statistics are online now. You can see it at http://macieira.org/blog/qt-stats. And come back every week, as it will update itself every Sunday to Monday evening.
Let me just point out the overall graph:
As you can see from the graph, the commit rate for the Qt Project was at its lowest during two days-off periods: New Years (week 52 of last year and week 1 of this year) and Easter (week 14). Aside from the first week of the project’s existence, it’s constantly been over 400 commits a week, and over 600 commits for 6 of the past 8 weeks. That’s impressive!
And answering the question of how much the project depends on Nokia, take a look at this other one:
You can see that the participation from Nokia developers still is quite high (and will probably remain so), at around 80%. But in turn that means around 20% of the commits going to the Qt Project come from other people, employed by other companies or in their free time, and this less than 6 months after the official launch of the Qt Project.
More than that, note the trend: Nokia’s participation tends to diminish, not because they’re doing less, but because others are doing more. The following graph, with Nokia’s numbers removed, shows the trend participation from others:
