Linux will turn 28 years old Today, On 25th August 1991, 21 years old Finnish computer science student Linus Torvalds sent a mail on a newsgroup(comp.os.minix) announcing that he was working on a new operating system which was ‘just a hobby, won’t be big and professional like GNU’.

A hobby project became the most Influential Kernel in history. Today we can say that “Linux is everywhere“, Because from super computer to stock exchanges to billboards to satellites to smartphones to windows everyone run on linux.

On 28th birthday of Linux Kernel, I am going to list out 12 interesting facts about Linux

  • Linux is not an OS, but it is the kernel, GNU Linux is the OS and it comes in several hundred flavours.
  • First Linux Kernel, version 0.01, had just 10,239 lines of code (Wikipedia)
  • The first commercial distribution of GNU/Linux was Yggdrasil and was launched in CD format in 1992.
  • Linus Torvalds release Linux under GNU General Public License (GPL). Linus Torvalds would have never written his own kernel if GNU would be having it’s own kernel and driver.
  • When Linus announced Linux, he didn’t actually announce Linux. It was not yet named, he just said “a free operating system” and that it resembled Minix. Later the name for Linux was going to be “Freax,” a combination of “free,” “freak,” and “x.” 
  • Steve Jobs offer a job to Linus Torvalds in 2000. Of course, the level of enlightenment is extremely good but comes with the condition that he stop developing the Linux project. The father of Linux (fortunately) rejected this “attractive” offer.
  • All of the 500 most powerful supercomputers run on Linux.
  • 90% of the public cloud workload runs on Linux.
  • 80% plus smartphones run on Android (based on the Linux kernel).
  • Even though Torvalds wrote 100% of Linux’s first release, his original contributions now account for less than 1% of its total code base. These days he says he’s too busy merging in code written by other contributors to do much programming himself.
  • Linux is available in many distributions, or “distros.” Most distros are based off of other distros. The most popular distro is Ubuntu, which is based off of Debian. Here’s the full Linux family tree:
  • Even Microsoft Windows — Linux’s biggest competing operating system — is embracing Linux. It recently integrated Linux kernel into the windows 10.

The Linux philosophy is ‘Laugh in the face of danger’. Oops. Wrong One. ‘Do it yourself’. Yes, that’s it.
