	abstract = {Researchers continue to demonstrate the benefits of Mining Software Repositories (MSR) for supporting software development and research activities. However, as the mining process is time and resource intensive, they often create their own distributed platforms and use various optimizations to speed up and scale up their analysis. These platforms are project-specific, hard to reuse, and offer minimal debugging and deployment support. In this paper, we propose the use of MapReduce, a distributed computing platform, to support research in MSR. As a proof-of-concept, we migrate J-REX, an optimized evolutionary code extractor, to run on Hadoop, an open source implementation of MapReduce. Through a case study on the source control repositories of the Eclipse, BIRT and Datatools projects, we demonstrate that the migration effort to MapReduce is minimal and that the benefits are significant, as running time of the migrated J-REX is only 30\% to 50\% of the original J-REX{\textquoteright}s. This paper documents our experience with the migration, and highlights the benefits and challenges of the MapReduce framework in the MSR community.},

	abstract = {Open source developers communicate with each other via various online outlets. Thus far, mailing lists have been the main coordination mechanism. However, our previous study shows that the use of developer IRC meetings is increasing in recent years. In this paper, we perform a study on the IRC meetings of two large open source projects: the GTK+ and Evolution projects. We explore three dimensions: who participates in the meetings, what do they discuss and how do they run the meetings. We find (1) that a small and stable number of the participants contribute the majority of messages in meetings, (2) that there are commonly discussed topics as well as project specific topics (3) that meeting styles vary across different projects.},

	abstract = {Developers of open source projects are distributed across the world. They rely on email, mailing lists, instant messaging, IRC channels and more recently IRC meetings to communicate. Most of the studies thus far focus on the use of mailing lists by OSS developers, however, an increasing number of open source projects are using IRC meetings to hold developer meetings. In this paper, we mine the $\#$gtk-devel IRC meeting channel and study the usage of the IRC meetings held by the GNOME GTK+ core developers and maintainers. We look at three different dimensions: the discussion volume of the meetings, the number of participants attending the meetings and the activity of these participants. Our findings show that IRC meetings are gaining popularity among open source developers and maintainers: the IRC meeting discussions are increasing in volume, have increasing attendance levels, and the participants actively contribute to the meetings. To the best of our knowledge, this is the first study on the use of developer IRC meetings by OSS developers.},

This is a potential problem since outdated comments may confuse or mislead developers who perform future development. Using data recovered from CVS, we study the evolution of code comments in the PostgreSQL project. Our study reveals that over time the percentage of commented functions remains constant except for early fluctuation due to the commenting style of a particular active developer.},
