I recently worked on two different C projects, and I wanted to structure them in a way that would make them easy to maintain and understand. I also wanted to make sure that the projects were easy to build and test. In this post, I will share my experience and the best practices I found for structuring C projects.

OpenID Connect (OIDC) is an authentication protocol that extends OAuth 2.0, providing a solid and standardized method for authentication often involving an ID token in the JWT (JSON Web Token) format. OIDC is the recommended way to authenticate with GitHub Enterprise Server when setting up GitHub Actions. Since the setup can be tricky, I've created a Terraform configuration that makes it easier to get started.
