The original Apollo 11 guidance computer (AGC) source code, in assembly, for the command module and lunar module, has been uploaded to GitHub. This source code has been transcribed or otherwise adapted from digitized images of a hardcopy from the MIT Museum. The digitization was performed by Paul Fjeld, and arranged for by Deborah Douglas of the Museum. This isn't the first time the code has been accessible online, but it is bringing new attention to the comments within it left by its authors. Within hours, coders began dissecting the software, particularly looking at the code comments the AGC’s original programmers had written. In programming, comments are plain-English descriptions of what task is being performed at a given point. But as the always-sharp joke detectives in Reddit's r/ProgrammerHumor section found, many of the comments in the AGC code go beyond boring explanations of the software itself. They’re full of light-hearted jokes and messages, and very 1960s references.[For example] there's code that appears to instruct an astronaut to “crank the silly thing around." |

The AGC code has been available to the public for quite a while – it was first uploaded by tech researcher Ron Burkey in 2003, after he'd transcribed it from scanned images of the original hardcopies MIT had put online. That is, he manually typed out each line, one by one.As enormous and successful as Burkey's project has been, however, the code itself remained somewhat obscure to many of today's software developers. That was until last Thursday (July 7), when former NASA intern Chris Garry uploaded the software in its entirety to GitHub, the code-sharing site where millions of programmers hang out these days. Editor's note: Threads merged. |

Interesting story on "Easter eggs" within the code: The entire source code for Apollo 11's flight computer software was recently posted to GitHub, a collaborative platform for developers, and it's filled with tons of hidden Easter eggs including jokes, a Shakespeare quote and a reference to the Black Power movement going on at the time. | |
