Dennis Ritchie Home Page
Using Stumble Upon!, I, well, stumbled upon Dennis Ritchie’s page. He’s famous as the creator of C and an early influential developer of Unix. Back when I was in school, we all learned C by reading Kernighan and Ritchie’s The C Programming Language. His homepage has some nice papers about the history of Unix, as well as some others on topics like cryptography and programming language design. Great stuff.
