Git from the Ground Up

" summary

Shows concrete internals: actual commands and outputs (git clone, git cat-file, git add/commit/push), prints SHA-1s and object contents, and inspects .git/objects layout. Demonstrates four object types (blob/tree/commit/tag objects), pack format details (a 17 MB pack file holding ~50k objects), and the delta-compression heuristic that sorts by type/name/size then applies a sliding-window delta compression. Explains fast‑forward vs recursive merge vs rebase with real commit parents.
