I am only 50% through. No code samples or object diagrams in this book. It’s more about how to approach what I do as opposed to specifically how to do it. I like have been thinking more about this myself and am finding this book very interesting.
I liked the book by the same author (with others) called Pragmatic Programmer. Bernie turned me onto that book when it first came out and I recommend it highly. It’s still as pertinent as the day it was written.
