Frases Donald Knuth

„The important thing, once you have enough to eat and a nice house, is what you can do for others, what you can contribute to the enterprise as a whole.“

—  Donald Ervin Knuth

„The psychological profiling [of a programmer] is mostly the ability to shift levels of abstraction, from low level to high level. To see something in the small and to see something in the large.“

„Beware of bugs in the above code; I have only proved it correct, not tried it.“

—  Donald Ervin Knuth
Donald Knuth's webpage http://www-cs-faculty.stanford.edu/~knuth/faq.html states the line was used to end a memo entitled Notes on the van Emde Boas construction of priority deques: An instructive use of recursion (1977)

„The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.“

—  Donald Ervin Knuth
p. 671 Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. Variant in Knuth, "Structured Programming with Goto Statements" http://pplab.snu.ac.kr/courses/adv_pl05/papers/p261-knuth.pdf. Computing Surveys 6:4 (December 1974), pp. 261–301, §1. Knuth refers to this as "Hoare's Dictum" 15 years later in "The Errors of Tex", Software—Practice & Experience 19:7 (July 1989), pp. 607–685. However, the attribution to C. A. R. Hoare is doubtful. http://shreevatsa.wordpress.com/2008/05/16/premature-optimization-is-the-root-of-all-evil/ All three of these papers are reprinted in Knuth, Literate Programming, 1992, Center for the Study of Language and Information
