Whatever I am today is just because of the Moral values taught by her To Dennis Ritchie and Ken Thompson - the creators of UNIX. I appreciate Ken Thompson’s work with B programming language and have been fond of programming in Ritchie’s invention: ‘C’ programming language since I was doing Engineering. I am a great admirer of the security features of Unix and used to love making shell scripts on UNIX operating sytem during my study days. Their achievments are the inspiration for the millions of programmers around the world.
