There is one required reading (beyond this web site): the following chapter on "ego-less programming" of the following book

• Weinberg. The Psychology of Computer Programming. Ch 4 "The Programming Group" Van Nostrand Reinhold Co., 1971

  This incredibly old book contains a lot of astute observations about the relationship between code and its creator, the software developer. Don’t get scared just because it uses code snippets from COBOL. The observations, and Weinberg’s suggestions on how to think about/react to them are good ones.
