As an “expert” (maybe experienced is better description?) programmer, I’ve found that most books are extremely beginner oriented and of little value. Yet, there are others I’ve found that as of my last reading improved my thought process, or expanded my mind in beneficial / fun ways.
One such book (which I read 5 years ago or more) is Bentley’s classic Programming Pearls. But, even this targets the early career in a lot of ways.
So, Lobsters, what books do you recommend for the mind expansion of a mid-career, individual contributor path programmer?
