Linux Is 25 Years Old

25 years ago, sometimes irascible and often potty-mouthed Linux creator Linus Torvalds gave us the Linux kernel, which led to the Linux operating system and it's derivatives. Linux is now found in most supercomputers, many web servers and a ton of mobile devices.
In 1984, Richard Stallman started working on GNU, a Unix-clone that stands, paradoxically, for “GNU’s not Unix.” By 1991, Stallman and company had successfully rewritten most of Unix, but they were missing one crucial component: the kernel, which is the fundamental core of an operating system—the part that talks to the hardware and translates the basic input from your keyboard, mouse, and touchscreen into something the software can understand. So Torvalds decided to create a kernel.
