The Gulf by Jack E. Davis. A history of the development of the Gulf of Mexico over the last 300 years sounds like it could be dull, but it is actually pretty interesting, though there is a ton of detail in here. Enjoying it — if I ever planned to the move to the Gulf Coast, this would be essential.
Concurrency in Go by Katherine Cox-Buday. Ok this is the far more essential book to read about Go, the intro to Go book I previously read should have had all this material. This is the interesting stuff.
