So passes a real hero of the computing age

I just heard that Dennis Ritchie passed away:

Dennis was co-inventor of the C Programming Language, which all modern computer operating systems are based upon, with Brian Kernighan, and co-inventor of Unix, with Ken Thompson.

Ritchie, Thompson and Kernighan were all big heroes and inspirations for me in my early career. Their influence is great; many, many people will not ever know how much influence these people have had on their daily lives.

RIP, Dennis. :’(
