Code ● “As you will find in multivariable calculus, there is often a number of solutions for any given problem.”― John Nash - Beautiful Mind ● The mythical man month - The joys of the Craft ● “I like solving problems, Commander. And Enigma is the most difficult problem in the world.” - Alan Turing - The Imitation Game ● The art of computer programming - Donald E. Knuth (fundamental, seminumerical, sorting and searching, combinatorial, mathematics preliminares redux, backtracking, dancing links and satisfiability)
