I was fortunate to have met Rear Admiral Grace Hopper at a Holiday reception when I worked as a DoD contractor at the Washington Navy Yard in 1985. I had been using COBOL for programming business systems for years and had the opportunity to thank her for it. She remarked that she was 'particularly proud' of that accomplishment.
I also think that the term 'bug' meaning an error or anomaly predates digital computers. My Father was trained during WW2 by the UASAAF in avionics and told me there were a lot of 'bugs' in the early airborne radar systems. I don't think my Father knew anything at all about computers ... - 73 and good DX de Mike, K6MKF, NCDXC Secretary > -----Original Message----- > From: [email protected] <elecraft- > [email protected]> On Behalf Of Dick Dievendorff > Sent: Saturday, November 07, 2020 10:58 > To: James Driskell <[email protected]> > Cc: Elecraft Reflector <[email protected]> > Subject: Re: [Elecraft] Tuner bug > > I think the term predates computers, but I have heard the story. > > https://www.atlasobscura.com/places/grace-hoppers-bug > > 73 de Dick, K6KR > > > On Nov 7, 2020, at 10:53, James Driskell <[email protected]> wrote: > > > > The first bugs in the old large 1st generation computers were actually > > insects > (bugs) that were raising havoc with the insulation.
