The Riverman methodologies for industrial networks.
Six frameworks, each addressing a different problem on the plant floor — from how networks are designed, to how they are secured, to how they are troubleshot, to how the people who run them learn the work. Each is small, named, and meant to be carried in the head.
Free to plant operators and industrial workers. Forever. Commercial use under the Riverman Fair License v2.0.
