Linux just turned 28 years old. From its modest beginnings as an interesting project to the OS that now empowers all 500 of the top 500 supercomputers, along with a huge variety of tiny embedded devices, its place in today's computing world is unparalleled.\nI was still working with SunOS at the time that Linux was announced \u2014 a couple years before it evolved into the System V based Solaris. The full ramifications of what it would mean to be "open source" weren't clear at the time. I was in love with Unix, and this clearly related newborn was of some interest, but not enough to draw me away from the servers I was managing and articles I was writing in those days.\n\nIt didn't take long for it to get my attention, along with that of a growing fan base. Over time, the open-source nature of Linux meant it was possible for well over 10,000 developers to help improve, add features, and enhance the security of the OS. It allowed others to tailor it to specific needs and specific devices. It also made it possible for developers to bundle software and make the OS easier to install and update.\nEven if you're walking around offices still dominated by Windows desktops, Linux is winning big time in some of the most important markets and remains the beating heart of the open source movement."\nToday, there are nearly 300 active distributions. Some target specific audiences and come prepackaged with special-purpose tools, such as Kali for penetration testing. Others are very general purpose.\nBy some accounts, more than 95% of the top 1 million web servers run Linux, along with over 90% of the public cloud and well over 80% of smartphones. So, even if you're walking around offices still dominated by Windows desktops, Linux is winning big time in some of the most important markets and remains the beating heart of the open source movement.\nHappy birthday, Linux! Here's to wishing you many decades of continued success, dedicated contributers, and happy users.
