Frases de John Backus

John Warner Backus foi um cientista da computação estadunidense.

Conhecido por criar a primeira linguagem de programação de alto nível - o Fortran -, a notação BNF e o conceito de programação em nível de funções.

Recebeu em 1977 o Prêmio Turing, por suas contribuições para o desenvolvimento de sistemas de programação de alto nível, principalmente por seu trabalho no Fortran e por publicações sobre métodos formais na especificação de linguagens de programação. Wikipedia

John Backus: Frases em inglês

“Much of my work has come from being lazy. I didn't like writing programs, and so, when I was working on the IBM 701 (an early computer), writing programs for computing missile trajectories, I started work on a programming system to make it easier to write programs.”

Quoted in the IBM employee magazine Think in 1979. Cited by his Associated Press obituary http://www.msnbc.msn.com/id/17704662/

“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. Many creative computer scientists have retreated from inventing languages to inventing tools for describing them. Unfortunately, they have been largely content to apply their elegant new tools to studying the warts and moles of existing languages.”

"Can Programming Be Liberated From the von Neumann Style?" http://dl.acm.org/ft_gateway.cfm?id=1283933&type=pdf, 1977 Turing Award Lecture, Communications of the ACM 21 (8), (August 1978): p. 614

“Von Neumann languages do not have useful properties for reasoning about programs. Axiomatic and denotational semantics are precise tools for describing and understanding conventional programs, but they only talk about them and cannot alter their ungainly properties. Unlike von Neumann languages, the language of ordinary algebra is suitable both for stating its laws and for transforming an equation into its solution, all within the "language."”

“You need the willingness to fail all the time. You have to generate many ideas and then you have to work very hard only to discover that they don’t work. And you keep doing that over and over until you find one that does work”
