I have a "summer of code" project. I'm a founder of Distribute Aid [1], a Swedish ngo that builds tech tools for refugee aid groups. We're an open source project [2] and are looking for people who can contribute.
There are opportunities to join us on the ground in Europe, or to volunteer remotely. We try to take a people-first approach and will match volunteers up with tasks / projects that they are most interested in. It's a great fit for students looking to build their resume while making substantial contributions to an important project.
If anyone is interested in learning more, shoot me an email at taylor /at/ distributeaid.org
If you're interested in summer of code projects, there's a good number of orgs in this year's google summer of code https://summerofcode.withgoogle.com/organizations/
This year I'm helping mentor the ZynAddSubFX organization https://summerofcode.withgoogle.com/organizations/6487755463... . Zyn is an open source musical synthesizer, so there's skills that are used in a number of domains, ranging from technical writing skills, to user experience knowhow, to musical backgrounds, user interface coding, hard realtime programming practices, to digital signal processing.
It's zyn's first year in GSoC, so it's going to be a learning experience on both sides, but it should be a good time. Outside of the official GSoC project we're always looking for contributors who are interested in learning new things.
