A plumber's guide to Git

Alex Chan | Friday 14:30 | Room J

Git is a key part of many modern development workflows. It's incredibly powerful, but its complexity and idiosyncratic user interface means we often treat it as a magic black box. How does it actually work?

When we understand our tools, we become more confident and effective users. In this workshop, we'll take a low-level look at how Git works under the hood.

We'll use Git plumbing commands to reproduce a typical Git workflow (add, commit, branch, and so on) -- and peer inside the .git directory to see what's really going on. Along the way, we'll answer questions like:

  • Where does Git store information? And how?
  • What's behind a branch?
  • What happens when we run checkout or reset?

Familiarity with basic Git will be helpful.
