in reply to Which non-Perl books made you a better (?:Perl )?Programmer?
The Pragmatic Programmer: From Journeyman to Master is reasonably good. More around coding than about coding, Hackers and Painters is also good. Agile and Iterative Development: A Manager's Guide is a nice introduction to agile methods and why they work (in simple language that even non-programmers can get).
