Maximilian Capraro, a member of our research group, wrote his Master Thesis based on work he performed at Boston-based start-up Black Duck Software (BDS). At BDS Max worked on the ohloh.net open source data service, specifically bug-tracker-based metrics gathering and reporting. That work has now gone live with a preview on ohloh.net. If you are interested in the research behind this work, check out his Master thesis on bug tracker metrics.
