Today I am grateful for.
Ken Thompson, Dennis Ritchie, Douglas McIlroy, Joe Ossanna, Brian Kernighan, and Peter G. Neumann.
If these names don't ring a bell, without them the thing you are reading this on might be very different. They and others, (i am sure i am forgetting someone), developed the first iteration of UNIX. The grandfather of all modern computer operating systems.
And, yes, LINUX runs the world, but its roots were planted by these guys.
