science/art/craft/trade/racket of software design and development

Je viens de retrouver un extrait d'un livre, dont j'ai perdu la référence.

Voici le titre du chapitre 3

"A test for practitioners of the science/art/craft/trade/racket of software design and development"

et ces deux citations :
"Ignorance, when voluntary, is criminal, and a man may be properly charged with that evil which he neglected or refused to learn how to prevent."
Samuel Johnson (1709-1784)

"Pure mathematices do remedy and cure many defects in the wit and faculties of individuals; for if the wit be dull, they sharpen it; if too wandering, they fix it; if too inherent in the sense, they abstract it."

Francis Bacon (1561-1626)
