git-hub/apollo-11

The source code used to program the Apollo 11 rocket has been published on GitHub. As this Quartz article points out, the history behind digitizing the code is a long and sorted tale but, ultimately, the most intriguing part about it all is the time capsule element to it. The code was, of course, written by humans in the 1960's and plenty of amusing method names and in-line comments made their way into the final product. How about a file named BURN_BABY_BURN--MASTER_IGNITION_ROUTINE? Or a comment, in the final stack, that reads TEMPORARY, I HOPE HOPE HOPE?

It goes to show, leaving amusing comments in your source code is not only beneficial to other programmers but might also end up being a time capsule into the era you wrote it.
