Git

Anthropic merged about 2,500 changes a day in May and more than 30,000 a day in September. Git's client could not keep up, so they inverted it. Between September 16 and October 15, 2026, every major lab hit the same wall and shipped the same primitive. Storage is solved. Deciding who wins a write is not.

How to use version control _properly_, and take advantage of it to save you from disaster, collaborate with others, and quickly find and isolate problematic changes. No more `rm -rf; git clone`. No more merge conflicts (well, fewer of them at least). No more huge blocks of commented-out code. No more fretting over how to find what broke your code. No more "oh no, did we delete the working code?!".
