Victoria,
I thought it was related to Ruby on Rails as well until I found the following on their site:
Rails Girls Summer of Code is programming language agnostic, and students have contributed to an overall of 76 unique Open Source projects such as Bundler, Rails, Discourse, Tessel, NextCloud, Processing, Babel, impress.js, Lektor CMS, Hoodie, Speakerinnen, Lotus (now Hanami) and Servo.
Maybe they've changed as the name is misleading when compared to that statement. So if OpenStack wanted to get involved we would submit an application and have some mentors/projects lined up similar
to Outreachy and Google Summer of Cone.
Thanks,
