    Six easy pieces of quantitatively analyzing open source projects

    I’ll be giving a talk at the Open Source Business Conference 2009 in San Francisco on March 24, 2009. The talk will present an easily accessible summary of our data-driven analytical work on how open source software development works. Here is the abstract: For the first time in the history of software engineering, we can…

  • Open source labor economics…

    Open source labor economics…

    …is not nearly as sexy a title for an industry talk as is “Open Source Hacker Careers” so it had to go. The result you can observe at the 2009 Open Source Meets Business conference in Nuremberg, Germany, on January 28th, 2009, when I will be giving a talk (almost) so named. Open Source Software…

  • How open source comments (by programming language)

    How open source comments (by programming language)

    We recently looked at the commenting practice of active working open source projects. It is quite impressive: The average comment density of open source is around 19%. (Comment density is the percentage of text that are comments, or, more formally: comment density = comment lines / (comment lines + source code lines); for example, two…

    Fabrizio Capobianco made the slides from his OSS 2008 keynote available. This is the same conference where we reported about the total (exponential) growth of open source. Unfortunately I had to leave right after our talk for the Wiki Symposium so I didn’t catch him nor could I listen to his talk. His slides, however,…

  • The dominance of small code contributions

    The dominance of small code contributions

    What is the most common size of code contributions to open source? Maybe 30 lines of source code? 200 lines? Or just one line? What’s your guess?

  • The commit size distribution of open-source software [HICSS 2009]

    The commit size distribution of open-source software [HICSS 2009]

    Authors: Oliver Arafat, Dirk Riehle Abstract: With the growing economic importance of open source, we need to improve our understanding of how open source software development processes work. The analysis of code contributions to open source projects is an important part of such research. In this paper we analyze the size of code contributions to…
