Last week, Dennis Richie 1941-2011 died. He was a man that had a very profound impact on our world. In the 1970s, with Ken Thompson, he created an operating system called UNIX at the Bell Labs. To develop UNIX, he created a computer programming language called C.
In today's computer and photography world, everybody is using his “stuff.” Every major modern computer operating system is written in C, the language that Dennis Ritchie created. Almost all operating systems are either derived or based on UNIX.
