This book is thin so I might have just read through it too quickly. Some of the anecdotes were pretty antiquated so they did not really appeal to me. I borrowed it from the library because it was mentioned in The Ruby Way (First Edition):

Thus spake the master programmer: “Though a program be but three lines long, someday it will have to be maintained.”

Geoffrey James, The Tao of Programming

If you plan to read it, good for you. But if you are not, there is probably nothing much that you are missing.
