50 years Unix

How I used Unix to get things done

“UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.” ~ Dennis Ritchie

Dennis Ritchie – created the C programming language and, with long-time colleague Ken Thompson, the Unix operating system.
Ken Thompson – an American pioneer of computer science and worked at Bell Labs for most of his career where he designed and implemented the original Unix operating system.
Brian Kernighan – a Canadian computer scientist who worked at Bell Labs and contributed to the development of Unix alongside Unix creators Ken Thompson and Dennis Ritchie.

Avoid vendor lock-in: looking forward to use open-source Linux for the next 50y 😉
