Communication and development networks represent the interactions among software developers. We explored the statistical relationships between file change proneness and a set metrics extracted from the issue tracker and version control system data to find the relative importance of each metric inunderstanding the evolution of file changes in the Rails project. Using hierarchical analysis, we found that code churn, number of past changes, and number of developers explain the evolution of changes in the Rails project better than Social NetworkAnalysis (SNA) metrics. Considering the relative importance of each predictor, wegot the same results. We also conducted a factor analysis and found that social metrics contribute to explain a group of files different from those explained by process metrics.

These communities’ sur-vival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers’ perceived efficacy is influenced by the use of an envi-ronment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSScoach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers’ self-efficacy by conducting a ques-tionnaire before and after the assignment. We found that pre-senting the information according to the model of barriers had a positive influence on newcomers’ self-efficacy, empowered the newcomers, making them more confident and comfortable dur-ing the contribution process. However, there is also some indica-tion that FLOSScoach did not lower the technical barriers.
