During a long time, software engineering research has been trying to better understand open-source communities and uncover two fundamental questions: (i) who are the contributors and (i) why they contribute. Most of these researches focus on well-known OSS projects, but little is known about the OSS movement in emerging countries. In this paper, we attempt to fill this gap by presenting a picture of the Brazilian open-source contributor. To achieve this goal, we examined activities from more than 12,400 programmers on Github, during the period of a year. Subsequently, we correlate our findings with a survey that was answered by more than 1,000 active contributors. Our results show that exists an OSS trend in Brazil: most part of the contributors are active, performing around 30 contributions per year, and they contribute to OSS basically by altruism.

These mechanisms may have different effects on peer impression formation. This paper describes a social network analysis of the WikiMedia project to determine which type of interaction has the most favorable characteristics for impressions formation. The results suggest that due to lower centralization, high interactivity, and high degree of interactions between participants, the code review interactions have the most favorable characteristics to support impression formation among FOSS participants.},

In this paper, we propose a layered approach to managing risks in OSS projects. We define three layers: the first one for defining risk drivers by collecting and summarising available data from different data sources, including human-provided contextual information; the second layer, for converting these risk drivers into risk indicators; the third layer for assessing how these indicators impact the business of the adopting organisation. The contributions are: 1) the complexity of gathering data is isolated in one layer using appropriate techniques, 2) the context needed to interpret this data is provided by expert involvement evaluating risk scenarios and answering questionnaires in a second layer, 3) a pattern-based approach and risk reasoning techniques to link risks to business goals is proposed in the third layer.

We analyzed peer code review data of the Android Open Source Project (AOSP) to understand whether code changes that introduce security vulnerabilities, referred to as vulnerable code changes (VCC), occur at certain intervals. Using a systematic manual analysis process, we identified 60 VCCs. Our results suggest that AOSP developers were more likely to write VCCs prior to AOSP releases, while during the post-release period they wrote fewer VCCs.
