Ken Thompson and Dennis Ritchie briefly explain UNIX at Bell Labs

A brief look at two men who were critical to the development of the modern computer. A shame more people don't immediately recognize their names while "Steve Jobs" is a household name. These two men have gravitas like few others in the world of computers. Their importance cannot be emphasized enough. Even though the media seemed to simply gloss over the death of Dennis Ritchie, let it be said here that both of their names are sacrosanct. 

In the video below, Thompson and Ritchie touch on how UNIX is used at Bell Labs, its design and makeup, and the purpose behind UNIX. You'll even catch a few hints of the UNIX philosophy in the presentation. Needless to say, the UNIX philosophy is the touchstone and guiding rod for UNIX development and improvement. The principles are timeless. 

The video is only a couple minutes long so it warrants a few viewings.
