The Git Parable - a different approach to understanding Git (90 min)
summary
90 minutes that builds a tiny Git-like VCS from a text editor and filesystem up so you see exact mechanics: snapshots become SHA-1 named objects, files become blobs and directories trees, snapshots become commit objects that point to parents, branches/tags are 40‑byte pointers, merges create commits with two parents, and the staging area controls what goes into each commit. Covers git commands (init add commit fetch merge rebase stash gc reflog), packfiles and delta compression, and Git LFS tradeoffs.
