ODHack 2.0


ODHack is back!

Mark your calendars: March 18-24 2024!

Remember, first comes, first serves so be prepared for D-Day! Issues tend to be assigned on the very first day.

We're excited to roll out the second edition of ODHack, building on the success of the first event! A big thank you to everyone who participated last time—we're aiming to make this edition even more impactful based on your feedback.

ODHack is set to become a regular event to support the open-source journey, which we know can sometimes feel like a solo adventure. The first ODHack set a solid foundation, creating a space where contributors could engage with open issues tailored to their skill sets, and we're eager to build on that.

This is why we want to make the ODhacks a monthly event - virtually and physically. This aims to welcome newcomers, promote open-source contribution, and support regular contributors interested in exploring new projects. It is also to help give projects a boost looking to onboard new contributors to further advance their goals!

So what’s up in this edition:

  • Continued rewards (& merch): Just like the first edition, we'll be recognizing your contributions with rewards, ensuring your efforts don't go unnoticed.
  • Global meetups: For the first time, we're hosting meetups in India (Indore), Costa Rica (San José), and Nigeria (Kaduna), offering you the chance to connect, collaborate, and share with fellow contributors in person!
  • Telegram Group: Join our new Telegram group to stay updated, follow through with projects more easily, and support one another. This community space is where we'll share important announcements and facilitate discussions!
  • Issues for all levels: A number of issues have been opened with many “good first issues” and others spanning different difficulty levels.

How to join the ODHack:

  1. Register on OnlyDust: If you haven't already, make sure to sign up on OnlyDust to participate and qualify for rewards.
