By now, you've heard the sad news about Dennis Ritchie, a man more influential than any billionaire CEO. I thought it'd be good to round up the many remembrances and relevant Dennis Ritchie-related posts that are accumulating in the blogosphere.

First, stop by dmr's homepage.

The Linux community's thoughts.

Tim Bray's thoughts.

An early dmr talk.

Rob Pike's Google Plus thread.

J.D.'s take on Ritchie.

Muppetlabs' poignant tribute.

SD Times' story.

Herb Sutter on Bjarne Stroustrup on Dennis Ritchie.

The other Dennis Ritchies

An interview with Stroustrup, Gosling, and Ritchie, from 2000.

Just a quick note to remind everyone that today is a fairly significant date in the history of open source software. In 1983, RMS sent this email.

From RMS' email:

Starting this Thanksgiving I am going to write a complete 
Unix-compatible software system called GNU (for Gnu's Not Unix), and 
give it away free to everyone who can use it.  Contributions of time, 
money, programs and equipment are greatly needed. 

Going by this date, the open source movement can be sait to be 27 years old. Does that place it in the all-important "30 years from creation to mainstream adoption" technology uptake path? Perhaps. But then, we're all interacting with open source software in the mainstream already, thanks to Linux-based phones, the Apache Web server, and about a billion little development tools. Happy birthday, GNU.

Brad Feld, on his blog, notes that on Valentines Day, next weekend, Unix time will be 1234567890. It's a bit of a cheat, and he admits this, but it's still very cool. Isn't Unix time supposed to end in 2038?
