The definitive deep dive into the .git folder

on YouTube ↗01h 07m

" summary

Shows exactly how commits, trees and blobs live inside .git by opening objects, inflating zlib blobs with a homemade unzipper node lib, walking hashes with git cat-file, and building a live commit explorer visualization that maps nodes and parents (it works, displays merges and dangling commits). Demonstrates pushing to a bare server, how git gc packs objects, that a repo stayed 48 KB locally, and that dangling commits are removed after ~2 weeks.
