    First computer bug found 64 years ago today

      Howdy,

       

      Since everyone that uses development tools has encountered bugs, I thought I'd post a fun history fact for Friday from the amazing Computer History Mesuem:

       

      September 9, 1945

       

      First instance of actual computer bug being found. At 3:45 p.m., Grace Murray Hopper records the first computer bug in her log book as she worked on the Harvard Mark II. The problem was traced to a moth stuck between a relay in the machine, which Hopper duly taped into the Mark II's log book with the explanation: First instance of actual computer bug being found.

      TGIF,

      P.S. Interesting, just noticed that Computer History Meseum states 1945 while the log book shows 1947.
