These was previously the last 200 pages of “Rapid Rails with Hobo”. As the latter was topping 500 pages, I reorganized and refactored them into two books that can be used as “companion” texts. “Rapid Rails with Hobo” includes the 27 tutorials. “Hobo Under the Hood” drills deeply into the infrastucture of Hobo and how it significantly enhances Rails.
