Conquest of the Moon (Viking Press, 1953, Wernher von Braun, Willy Ley, Fred Whipple) describes a lunar expedition that could be accomplished with the technology of 1950.

Von Braun and company left no detail unexamined. One of the less obvious categories that they put a lot of effort into is navigation, or in this context, astrogation.

I ran across an engineering aphorism or principle called “Gall’s Law”:

GPP is the General Purpose Preprocessor, a macro preprocessor for various forms of structured and unstructured text.

A quine is a computer program which takes no input and produces a copy of its own source code as its only output. There’s usually a few conditions on what the program can do, like not reading it’s source code during execution.

I wrote what I believe to be the first non-vacuous quine ever in the GPP language.
