Edsger W. Dijkstra Browse All Authors Top 4 quotes by Edsger W. Dijkstra Program testing can be used to show the presence of bugs, but never to show their absence! Edsger W. Dijkstra The argument against recursive procedures was always an efficiency argument: non-re-entrant code could be executed so much more efficiently. But with the advent of multiprogramming another need for felxible storage allocation has emerged. And if there are still machines in which the use of recursive routines is punished by too heavy a penalty, then I would venture the opinion that the structure of such a machine should now be called somewhat old-fashioned. Edsger W. Dijkstra The question of whether Machines Can Think ... is about as relevant as the question of whether Submarines Can Swim. Edsger W. Dijkstra The teaching of BASIC should be rated as a criminal offence: it mutilates the mind beyond recovery. Edsger W. Dijkstra
