That's a great blog post, and the video alludes to it. But it covers the same ideas in only the loose sense that it's about some of the same topics since it's by the same author. But it's 13 years older than the video.

It seems to me that the technique goes back at least to the battle of Monterey during the American invasion of Mexico: https://www.gutenberg.org/cache/epub/4367/pg4367-images.html... .
