It's a very solid broad programming book! I thought it was going to be too generic or over hyped, but it was solid. That said, I do find the most interesting software books to be about specifics, but that's nothing against this book.

Out of the classic broad books that get recommended all the time, this is one of the best IMO. I really don't like Clean Code (Martin's follow up, Clean Architecture is fantastic, though). Refactoring by Fowler is also a great generalist language and system book (but a specific topic).
