How to Get Started

STEP 1
THE STORY (3 minutes)
  1. September 9, 1947 at Harvard University
  2. Grace Hopper and team working on the Mark II computer
  3. The computer (huge, room-sized, using mechanical relays) kept malfunctioning
  4. They opened it up and found... an actual moth stuck in relay #70
  5. Grace taped the moth in the logbook with note: 'First actual case of bug being found'
  6. The moth is still preserved at the Smithsonian!
STEP 2
THE CONTEXT (3 minutes)
  1. 'Bug' already meant malfunction in engineering (Thomas Edison used it in 1870s)
  2. But this was the first literal bug causing a computer problem
  3. Mark II used electromechanical relays - physical switches clicking on/off
  4. Insects were attracted to the warmth and light
  5. Modern computers don't have this problem (solid state, sealed)
  6. 'Debugging' became official term for fixing computer problems
STEP 3
GRACE HOPPER'S LEGACY (2 minutes)
  1. Grace Hopper: pioneering computer scientist, Rear Admiral US Navy
  2. Invented first compiler (translates human-readable code to machine code)
  3. Popularized term 'debugging' through this incident
  4. She'd later say: 'From then on, when anything went wrong, we said we were debugging the computer'
  5. Phrase spread throughout computing world
STEP 4
CONNECTION TO TODAY
  1. Every time a programmer 'debugs' code, they're referencing this 1947 moth
  2. The moth photo is one of computing's most famous images
  3. Reminds us that even revolutionary technology had humble, humorous moments
