Farewell, Dennis Ritchie

He was father of the C programming language and without him there would be no UNIX. His pioneering work paved the way for many modern programming / scripting languages like Objective-C, C#, Perl, Java, Go, JavaScript and PHP. Entire operating systems are written in C or build upon the UNIX legacy, most notably BSD and hence Mac OS X. Farewell, Dennis Ritchie… may you rest in peace.
