Slides for my talk at OSCON, Portland, 2014. Video: https://vimeo.com/105213660
Understanding the inner life of free / open source software projects is of fundamental importance to developers, users and decision makers. This talk helps to understand what's happening behind the curtains in the most relevant open cloud platforms, by analyzing the rich data obtained from their developing repositories.
The talk covers, for the four analyzed projects, the following topics:
* How open is their development model, and to which extent they provide access to their development data.
* Some parameters related to the overall activity and effort put into the development and maintenance of their products.
* The main characteristics of their development community: size, diversity, engagement, attraction, etc.
* The main parameters characterizing their performance, such as time-to-fix tickets or time-to-review patches.
* Some visualizations of the most relevant aspects.
All the tools used to produce the analysis presented in this talk are free, open source software, based on the Grimoire technology http://vizgrimoire.github.io
