Abstract

This project brings together two undergraduate research initiatives focused on the Linux kernel, addressing recurring challenges in software engineering for large-scale, community-driven projects. The first initiative investigates code duplication in kernel subsystems, identifying recurring patterns, proposing refactorings, and contributing patches to the project. The second initiative aims to study and implement a Continuous Integration (CI) infrastructure, applying DevOps practices and contributing to free software tools that support automated testing in the Linux kernel development workflow. Both efforts combine hands-on activities with qualitative methods, including participant observation, to generate empirical knowledge about collaborative free software development. Expected outcomes include direct contributions to the Linux kernel, the development of support tools, and scientific publications on the technical and social dimensions of these practices. (AU)
