Summary

Finnish-American software engineer who created the Linux kernel (1991) — the operating system that runs most of the world's servers, Android phones, and supercomputers — and Git (2005) — the version control system used by virtually every software developer on Earth.

Core Contribution

Created the dominant server operating system and the universal version control system — Linux's open-source model (combined with the GPL license) proved that collaborative open-source development could build better software than corporate teams; Git's distributed model solved the fundamental problem of coordinating code changes across thousands of contributors.

Key Spikes & Highlights

  • Release Early Release Often (Linus's open source development philosophy: make your code available to the world as soon as it barely works, and incorporate contributions aggressively; this maximizes the number of people who can find and fix bugs, which produces better software faster than closed development; the internet enables the coordination that makes this work)
