20 years gone — what can we learn from Git's history?
summary
Covers Git’s origin in 2005 when Linux moved off BitKeeper and a new version-control tool was created quickly as self-hosting scripts. Explains key design choices—content-addressed objects (blob/tree/commit using SHA‑1), minimal plumbing APIs that enable features like stash and reflog, and the distributed model tuned for performance (first Linux kernel merge in ≈10 days, tracked ~4.5M LOC). Notes ongoing work to add SHA‑256 support to address hashing concerns.
