Today, Linux is the most widely deployed operating system on earth, though its presence is often invisible to consumers.
Mobile Supremacy: In 2008, Google introduced Android, an operating system built on top of a modified Linux kernel. It now runs on billions of smartphones globally.
Supercomputing and Infrastructure: Linux runs 100% of the world's top 500 fastest supercomputers. It dominates the public cloud, powering the vast majority of infrastructure on AWS, Google Cloud, and Microsoft Azure.
Embedded Systems: From smart TVs and Wi-Fi routers to the infotainment systems in modern vehicles and the flight computers on SpaceX rockets, Linux serves as the standard embedded backend.
What began as a single student's self-described "hobby" project evolved into a masterclass in collaborative engineering, demonstrating that decentralized, open-source development could successfully build and maintain the digital foundation of the modern world.
This site is by a Linux user who started with Alcyon Regulus OS on a 68000 VME workstation back in 1991. Regulus was developed by Alcyon, San Diego, CA. It featured a real-time version of Unix compatible with Unix System V. It used pSOS kernel in combination with its own version of Unix. It runs 3 on 80386, 680x0, and 32000. Real-time enhancements to Regulus include multitasking priority based scheduler, memory areas that can be directly accessed and shared by tasks, and intertask event signaling.Â
