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. %B Open Source Software: Mobile Open Source Technologies %S IFIP Advances in Information and Communication Technology %I Springer Berlin Heidelberg %V 427 %P 202-211 %@ 978-3-642-55127-7 %U http://dx.doi.org/10.1007/978-3-642-55128-4_30 %R 10.1007/978-3-642-55128-4_30
