Today is the 66th anniversary of the first computer bug

Sixty-six years ago today (on 1947-09-09) operators of the Mark II Aiken Relay Computer being tested at Harvard found a dead moth trapped between points of Relay #70 in Panel F. Dr. Grace Hopper made an entry in the Mark II log book and identified it as the "first actual case of bug being found". (source)
