There's no doubt that it's a very extensive book on software development and a very good one but I personally don't recommend it. If one really wants to know about software development, I find that it's much better to join an open source project and discuss the development of the project with other people than just reading about software development. It's almost the same thing as learning everything about an internal combustion engine but having no idea how to fix one.
In hindsight perhaps I shouldn't have bought the kindle edition of the book (Code Complete) because it's a very large book and it's not those kinds of books where we must read from cover to cover and I don't think it's very practical to read those books in a kindle but perhaps it's just me. Just my 2 cents.
