How They Built it: The Software of Apollo 11

LinuxScribe writes: When Apollo 11's Lunar Module landed on the Moon 40 years ago this week, the software that helped take humans to another celestial body was essentially built using paper-tape rolls and thick cardstock that was punched with special holes. It wasn't open source in the sense we know today, but it was built for NASA under contract, then was tested, modified and fine-tuned by NASA engineers in ways that are similar to open source projects nowadays.
