Some recommended books for improving as a software developer

Most software books are too language specific and go out of date too quickly. What I find has stayed with me are books about bigger concepts, such as systems thinking and complexity, and also so-called "soft skills" such as management and psychology.

User experience

These are all really about developing empathy for other people :)

; To begin demonstrating the problem, we first need some
; "legacy code" with datastructures and functionality:

;; Clojure 1.5.1
=> ; coll (fn [f acc]) renvoie (reduce f acc coll)
=> ; coll (fn [f init]) renvoie (reduce f init coll)
=> (defn fnil [f init] init)
WARNING: fnil already refers to: #'clojure.core/fnil in namespace: cljug.core, being replaced by: #'cljug.core/fnil
#'cljug.core/fnil
=> (reduce + 0 nil)
0
=> (fnil + 0)

;                    Stumbling towards Y (Clojure Version) 
; 
; (this tutorial can be cut & pasted into your IDE / editor)  
; 
; The applicative-order Y combinator is a function that allows one to create a 
; recursive function without using define. 
; This may seem strange, because usually a recursive function has to call 
; itself, and thus relies on itself having been defined. 
; 
; Regardless, here we will stumble towards the implementation of the Y combinator.
