Programming languages – Wikiquote

The source code for a simple computer program written in the C programming language. When compiled and run, it will give the output “Hello, World!”

A programming language is a machine-readable artificial language designed to express computations that can be performed by a machine, particularly a computer. Programming languages can be used to create programs that specify the behavior of a machine, to express algorithms precisely, or as a mode of human communication.

A – F[edit]

  • Programs must be written for people to read, and only incidentally for machines to execute.
  • For twenty years programming languages have been steadily progressing toward their present condition of obesity; as a result, the study and invention of programming languages has lost much of its excitement. Instead, it is now the province of those who prefer to work with thick compendia of details rather than wrestle with new ideas. Discussions about programming languages often resemble medieval debates about the number of angels that can dance on the head of a pin instead of exciting contests between fundamentally differing concepts.
  • That language is an instrument of human reason, and not merely a medium for the expression of thought, is a truth generally admitted.
  • Cheatham’s amendment of Conway’s Law: If a group of N persons implements a [COBOL] compiler, there will be N-1 passes. Someone in the group has to be the manager.
  • When FORTRAN has been called an infantile disorder, full PL/1, with its growth characteristics of a dangerous tumor, could turn out to be a fatal disease.
  • The use of COBOL cripples the mind; its teaching should, therefore, be regarded as a criminal offence.
  • Write a paper promising salvation, make it a ‘structured’ something or a ‘virtual’ something, or ‘abstract’, ‘distributed’ or ‘higher-order’ or ‘applicative’ and you can almost be certain of having started a new cult.
  • About the use of language: it is impossible to sharpen a pencil with a blunt axe. It is equally vain to try to do it with ten blunt axes instead.
  • If there is ever a science of programming language design, it will probably consist largely of matching languages to the design methods they support.
  • To the designer of programming languages, I say: unless you can support the paradigms I use when I program, or at least support my extending your language into one that does support my programming methods, I don’t need your shiny new languages.

G – L[edit]

  • SQL, Lisp, and Haskell are the only programming languages that I’ve seen where one spends more time thinking than typing.
  • Typing is no substitute for thinking.
    • Richard W. Hamming cited in: John G. Kemeny, ‎Thomas E. Kurtz (1987) Structured BASIC programming. p. 118
  • At first I hoped that such a technically unsound project would collapse but I soon realized it was doomed to success. Almost anything in software can be implemented, sold, and even used given enough determination. There is nothing a mere scientist can say that will stand against the flood of a hundred million dollars.
  • My original postulate, which I have been pursuing as a scientist all my life, is that one uses the criteria of correctness as a means of converging on a decent programming language design—one which doesn’t set traps for its users, and ones in which the different components of the program correspond clearly to different components of its specification, so you can reason compositionally about it. […] The tools, including the compiler, have to be based on some theory of what it means to write a correct program.

M – R[edit]

  • Computer languages of the future will be more concerned with goals and less with procedures specified by the programmer.
  • Computer scientists have so far worked on developing powerful programming languages that make it possible to solve the technical problems of computation. Little effort has gone toward devising the languages of interaction.
  • Programmers should never be satisfied with languages which permit them to program everything, but to program nothing of interest easily.
  • When someone says “I want a programming language in which I need only say what I wish done,” give him a lollipop.

S – Z[edit]

  • If someone claims to have the perfect programming language, he is either a fool or a salesman or both.
  • Some people, when confronted with a problem, think “I know, I’ll use sed.” Now they have two problems.
