Git Branches: Intuition and Reality
Summary: In this post, Julia Evans discusses the intuitive mental model people have about git branches and how it differs from git's actual representation. She explains that while the intuitive model sees a branch as an offshoot with a parent, git defines a branch as the full history of every previous commit. Despite the differences, the intuitive model aligns with how git is used in practice, such as in rebases, merges, and pull requests. However, git's lack of hierarchy between branches can be confusing, as it requires users to explicitly specify the relationship between branches when running git commands.

Write libraries instead of services, where possible
Summary: Write libraries instead of services when possible to lower costs for developers and provide the same functionality to users. Libraries are user-run software like shared objects, modules, and servers, while services depend on a provider for functionality. Libraries prevent users from negatively impacting others by not sharing state or resources, saving administration costs. Both standalone servers and importable code are equally expressive and cheap to administrate, benefiting both developers and users.
