History Of Linux

  1. 1. History of Linux Anand vasudevan
  2. 2. • Linux evolved from a project started by a university student to the robust OS it is now
  3. 3. • In June 1971, Richard Matthew Stallman joined MIT Artificial Intelligence Laboratory as a programmer where he gained popularity with the hacker community and came to be known by his now popular name RMS. • At that time, all the programmers used to share their code freely among each other cutting across various institutions
  4. 4. Richard Matthew Stallman
  5. 5. • In 1980, with the advent of portable software - ie software that can be compiled to run on different computers, a business model emerged. • So the companies developing the code refused to share the code with their clients and began restricting copying and redistribution of their software by copyrighting it.
  6. 6. • In response to this trend, Stallman, who believed in the principle that software has to be free always, founded the Free Software Foundation and in 1985, published the GNU Manifesto. • This manifesto outlined his motivation for creating a free OS called GNU, which would be compatible with Unix. • He along with a group of like minded programmers started work in developing the tools needed to make a complete OS
  7. 7. • In the same year (1985), a professor by name Andy Tanenbaum wrote a Unix like Operating system from scratch for the Intel i386 platform. • He named it Minix.

  9. 9. • In 1989, Stallman released the first program independent GNU General Public Licence now popularly known as GPL or copyleft. • Now the only thing that GNU lacked was a completely free OS kernel
  10. 10. • In 1990, A finnish student by name Linus Torvalds studying in the University of Helsinki came into contact with Andy Tanenbaum's OS, Minix. • Linus wanted to upgrade Minix by putting in more features and improvements. • But he was prohibited by Tanenbaum to do so. • Then Linus decided to write his own kernel and released it under GPL. • This kernel is now popularly known as Linux

  12. 12. Tux the penguin: Linux’s Dear Logo
  13. 13. • The logo of Linux is a penguin • His cute logo has a very interesting history • Initially no logo was selected for Linux.
  14. 14. • Once Linus went to the southern hemisphere on a vacation • There he encountered a penguin • As he tried to pat it, the penguin bit his hand. • This amusing incident led to the selection of a penguin as the logo of Linux sometime later.
  15. 15. Linus Speak • “If you want to travel around the world and be invited to speak at a lot of different places, just write a Unix operating system”
