Talk — Git Under the Hood
A talk about Git's storage model, commits, integrity, and the ideas hidden behind familiar commands.
What is behind Git? How does it think? What storage model does it use? What happens behind the scenes when we create a commit, and how does Git protect the integrity of its data?
Understanding that model makes it much easier to evolve a codebase with confidence. Instead of memorising commands and hoping they fit the situation, we can reason about the objects and references Git is actually changing.
The talk was designed for every level of experience. People new to Git could see what happens behind each command and build a stronger mental model from the beginning. Daily users could look more deeply at the mechanics they already relied on and use Git with greater awareness.
