In case you didn't know, October is the month of open source. Why? DigitalOcean organizes Hacktoberfest, a program where you contribute to open-source and get a super-cool shirt (and some stickers) in return.

But it isn't just DigitalOcean. Multiple organizations will also give you swag if you contribute to their repositories on Hacktoberfest. Here's a complete list of all promotions:
