I read today (“Dennis Ritchie, Father of C and Co-Developer of Unix, Dies“) that Dennis Ritchie had died. As anyone familiar with computer science knows he made huge contributions to the advancement of computing. He was the creator of my favorite (and still widely used) programming language C. He was also a key contributor to the development of the Unix Operating System. From Unix were derived Linux and macOS, both of which are widely used today alongside Unix.
He will be missed!
