💡 TIL: GitHub Actions secrets become empty strings in a PR from a forked repository. Apparently it's a security feature, not a bug! We learned this the hard way and wrote up our learnings in case it's helpful to others 👉 2i2c.org/blog/2025/gi...

GitHub Action secrets are only available from non-forked repositories! | 2i2c

If you’ve worked with GitHub Actions in open source projects, you might encounter a hard-to-debug error where repository secrets are simply empty. That’s probably because the PR is from a forked…

Our new approach to foundational open source contributions focuses on two key objectives: increasing casual but returning contributors AND growing the number of maintainers in communities like JupyterHub.

2i2c @2i2c.org · 28d

Doing this is surprisingly hard! It requires thinking about upstream contributions as a group, training team members so they're comfortable doing it, and ensuring that we don't become too-imbalanced in one contribution or another.

1

2i2c @2i2c.org · 28d

To ensure we make both types of contributions strategically, we make intentional time for our team members to make each type of contribution, and own both of them as a *team* rather than a collection of individuals.

1

2i2c @2i2c.org · 28d

We think of these contributions very differently - we can't just contribute what we want when we want it, we also have to create a healthy team and community system that we can participate in - this both benefits us, and the broader ecosystem.

1

2i2c @2i2c.org · 28d

Our key strategy: differentiate "Directed" contributions (driven by our product roadmap and requests from our member communities) and "Foundational" contributions (driven by the *open source community's needs* and lead to a strong foundation).
