Tech Talk: Linus Torvalds on git

Caption notes

In a 2007 Google Tech Talk, Linus Torvalds draws on Linux kernel maintenance to explain how distributed version control changes collaboration. Teammates can commit in their own repositories, pull and test each other’s changes, and then ask a maintainer to integrate the work. When a conflict calls for expertise he lacks, Torvalds asks someone familiar with the code to resolve it in their own repository and send a new pull request. He also explains why fast merges were an early Git design goal: the cost of merging affects when and how often developers integrate changes. This guide focuses on the workflow described at the time. Performance and security claims were not independently verified, and early implementation details are not presented as current specifications.
