[code] The lines of code that changed everything … A list of software that changed the world. ‘The Apollo 11 Lunar Module’s BAILOUT Code – The [Apollo Guidance Computer] software team knew there were eventualities they couldn’t plan for. So they created BAILOUT. When the computer was at risk of running out of space (or “overflow”), the AGC triggered BAILOUT to schedule less important data and operations so it could keep the vital ones up and running. As the Eagle lander descended toward the moon’s surface, at 30,000 feet the AGC flashed a “1202” alarm, which neither Neil Armstrong nor the flight controller in Houston immediately recognized. But in less than 30 seconds, the computer experts in Mission Control relayed that the AGC software was doing just what it was supposed to: drop lower-priority work and restart the important jobs (so quickly that it was imperceptible to the crew).’
