Learning Git branching interactively

Summary

Peter Cottle develops a visual practice environment in which Git commands change a commit graph immediately. Learn Git Branching runs in the browser. It covers rebase, cherry-pick and remotes.

Ideas

  • Every exercise has a visible starting graph and target graph.
  • Commands change branches, commits and HEAD with animation.
  • Local and remote operations are practised separately.
  • Mistakes can be undone and repeated without risk.

Insights

  • Visualisation connects commands with their actual data model.
  • Safe sandboxes encourage experiments with operations that seem risky.
  • Task-based feedback makes abstract graphs manageable.

Facts

  • The project is open source.

Recommendations

  • Solve exercises without hints first.
  • Then carry out the same workflow in a test repository.

Git flow: a successful branching model

Vincent Driessen describes a strict Git model with long-lived main branches and short-lived branches for features, releases and bug fixes. An understandable model can improve coordination and still be too heavyweight for small teams. Branching rules only work together with clear rules for tests, reviews and releases.

Linux's first Git commit and colliding SHA prefixes

Kees Cook demonstrates in practice why automated Linux tools must not treat Git commit prefixes as unique identifiers. The colliding prefix is 1da177e4c3f4. At the time, 590 Linux commits used this prefix in Fixes tags.

The biggest and weirdest Linux kernel commits

Gary Bernhardt examines extreme objects in the Linux Git history and explains how imports, tools and data formats create surprising outliers. The Linux kernel has a very large public Git history. Git addresses objects via cryptographic hash values.
