Hunt for Red October was the very first thing I thought of when seeing the title on here. Nice reconstruction of ping.

  Ping goes back a long way. It was originally written by Mike Muuss while at the U. S. Army Ballistic Research Laboratory, in 1983, before I was born.

Back when my serious LOC output years were really starting to ramp up .. fun times.

I recall Ping being late to board his sailing vessel, and took a countermeasure to his backside.

To Wit:

*Excellent, heart-warming tale of exploration and discovery. Using deft allegory, the authors have provided an insightful and intuitive explanation of one of Unix’s most venerable networking utilities. Even more stunning is that they were clearly working with a very early beta of the program, as their book first appeared in 1933, years (decades!) before the operating system and network infrastructure were finalized.*
