Linux Turns 33: A Celebration

2024 marks the 33rd anniversary of Linux, the influential operating system that began as a modest project.

From a Small Hobby to Global Adoption

On August 25, 1991, 21‑year‑old Linus Torvalds posted on the comp.os.minix newsgroup that he was developing a free operating system for 386/486 AT clones, describing it as “just a small hobby”.

“Hello friends of minix— I am working on a free operating system (just a small hobby, not as big and professional as GNU) for 386/486 AT clones… I have already ported bash (1.08) and gcc (1.40)… I would like to hear your feedback.” — Linus Torvalds, 1991

Thirty‑three years later, that hobby has grown into a system that powers millions of computers worldwide, from desktops and servers to mobile phones, routers, smart appliances, televisions, satellites, supercomputers, Wall Street trading platforms, and even the International Space Station.

Linux’s Ubiquity Today

Even users who never directly interact with Linux benefit from its presence, as it silently underpins many everyday devices and critical infrastructure.

Looking Forward

As we raise a glass to Linux’s birthday, the community looks forward to continued innovation and surprises in the years ahead.
