And those of us who worked with Joe knew him in all of his sometime irascible, often funny moods. Joe was always one of our favorite people, and we are devastated to report that he died at home, unexpectedly, last night.
Joe Barr was a reporter and editor for Linux.com, which is owned by the same company that owns Slashdot."

Any system which depends on human reliability is unreliable.
