Linux was announced by Linus Torvalds 35 years ago today — humble OS started with 10,000 lines of code but has now grown to 40 million, dominates global infrastructure

Thirty-five years have passed since Linus Torvalds announced Linux.

Linux grew from a hobby kernel of about 10,000 lines into a project with tens of millions of lines of code.

It now underpins global computing infrastructure, including web servers, supercomputers, Android devices, and embedded systems.

Built on an open-source model, Linux has become a major alternative to proprietary software.
