As a Google Summer of Code student at AnitaB.org Open Source, I got to propose a project to be implemented from scratch and work on it on many levels and from the perspective of both contributor and maintainer. So in this talk, I will provide my insights over why it can be helpful to your career to contribute to Open Source, where you can get started with it (OS communities, initiatives, projects, etc) and how you can actually contribute in multiple ways to Open Source, whether you’re a developer, designer, tester… or just a curious person who wants to contribute to a project you care about.
