Veteran developers' contributions and motivations: An open source perspective

Decades of psychology and sociology research demonstrate that humans change cognitively and socially as they age, so it stands to reason that software developers likewise undergo changes that may affect their work. In this paper, we investigate age-related differences in software developers through the lens of open source software, which is built in communities that tend not to include older software developers. We report on the results of a qualitative panel discussion, then quantitatively analyze such veteran developers' activities on StackOverflow, to understand why few veteran software developers' participate in open source, and how their contributions to software development differ from their younger peers. Our results suggest that veterans' are less motivated by social interactions than their younger peers. Our results also suggest that veterans could contribute a broader knowledge of software development than their younger peers, as well as knowledge of old technologies that can be applied to newer technologies.
