ABC x Hacktoberfest

Personal development
Useful for first-year students

October is Hacktoberfest, and GEWIS is joining the global celebration of open source! Throughout the entire month, we invite all members, especially first-years, to dive into the world of open source software and contribute to the projects that power our association.

Hacktoberfest is a worldwide event that encourages people to learn, collaborate, and give back to the open source community. At GEWIS, the ABC manages the software that keeps our association running smoothly. This month, we are opening up our projects to anyone eager to learn new skills, write some code, and make meaningful contributions.

You can participate at any time during October. Whether you want to fix a small issue, improve documentation, or add a new feature, there’s something for everyone. The ABC (and other GEWIS developers) will be available throughout the month to help you get started and guide you through the process.

You can contribute to any of the following projects:

  • SudoSOS Backend: The logic behind our bar system, written in TypeScript. It powers transactions in the GEWIS room and at social drinks. You can see the GitHub repository.
  • SudoSOS Frontend and POS: The web interface at sudosos.gewis.nl and the Point of Sale system on the kitchen screens, both part of the same monorepo. Written in TypeScript and now fully migrated to Vue 3. You can see the GitHub repository.

How to Join:

  1. Register for Hacktoberfest at hacktoberfest.com
  2. Pick a project that interests you — or find one with the hacktoberfest tag on GitHub or GitLab
  3. Start contributing anytime during October
  4. Ask for help from the ABC or other GEWIS developers — we’re here to guide you 
  5. Have a chance to win one of our cool prizes!
