The document describes a free software course for undergraduate students at Université Paris Diderot that has been offered annually since 2007. The course consists of 8 weeks of lectures covering topics like the history and philosophy of free software, followed by 4-5 weeks where students complete individual research projects on free software topics and present their findings to the class. Typical project topics include prominent figures in the free software movement, Linux distributions, free software projects like Wikipedia, and social issues related to free software. The goal is to introduce students to the concepts of free and open source software through classroom instruction and hands-on projects.
