  • Modeling micro-blogging adoption in the enterprise [AMCIS 2009]

    Modeling micro-blogging adoption in the enterprise [AMCIS 2009]

    Abstract: Despite a broad range of collaboration tools already available, enterprises continue to look for ways to improve internal and external communication. Micro-blogging is such a new communication channel with some considerable potential to improve intra-firm transparency and knowledge sharing. However, the adoption of such social software presents certain challenges to enterprises. Based on the…

    Micro-blogging in the enterprise: Focus groups evaluation results

    A couple of weeks ago, Oliver Günther and I reported about the results of the Micro-Blogging in the Enterprise Focus Groups we had undertaken in December 2008. The report was an internal talk at SAP Labs LLC in Palo Alto and drew a record audience. I’m glad to report that we can publish the slides…

  • Estimating commit sizes efficiently [OSS 2009]

    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

    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…

  • The comment density of open-source software code [ICSE NIER 2009]

    The comment density of open-source software code [ICSE NIER 2009]

    Author: Oliver Arafat, Dirk Riehle Abstract: The development processes of open source software are different from traditional closed source development processes. Still, open source software is frequently of high quality. Thus, we are investigating how open source software creates high quality and whether it can maintain this quality for ever larger project sizes. In this…

  • There is no “donating code to the community”

    There is no “donating code to the community”

    There, he said it again, at the Open Source Meets Business conference in Nuremberg, Germany: “We would like to donate this code to the community.” Sounds great, doesn’t it? Well, I’m not so sure. Or, to be frank, I think if somebody talks about donating code to the community they probably don’t understand effective open…
