Google Summer of Code, informally called GSoC, is a global, online mentoring program focused on introducing new contributors to open source software development. GSoC contributors work on a 12+ week programming project with the guidance of mentors from their open source organization. At 52°North, we pair the contributors with mentors and embed their work in the context of ongoing research projects. Hence, GSoC contributors gain valuable exposure to real-world software development scenarios and have the opportunity to work in areas related to their career pursuits. In turn, we are able to improve our software projects, as well as identify and draw in new developers more easily.
