Build your own git from scratch, and watch its hashes match the real thing

Short summary

Learn how git works by rebuilding it in ~150 lines of Python. The tutorial explains git's content-addressed architecture through working code that produces byte-for-byte identical output to real git. Discover that branches are just text files, commits are snapshots, and git's power comes from content hashing and object deduplication.

• •Rebuild git's core in ~150 lines of Python with output matching real git exactly
• •Understand content addressing: identical content produces identical hashes, enabling efficient storage
• •Learn git internals: blobs (files), trees (directories), commits (snapshots), and branches (text file pointers)
