“In the development of our understanding of complex phenomena, the most powerful tool available to the human intellect is abstraction. Abstraction arises from a recognition of similarities between certain objects, situations, or processes in the real world, and the decision to concentrate on these similarities, and to ignore for the time being the differences.”
Tony Hoare
“What is the central core of the subject [computer science]? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline? My answer to these questions is simple—it is the art of programming a computer.”
— Tony Hoare Primary source“There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies.”
— Tony Hoare Primary source“The price of reliability is the pursuit of the utmost simplicity.”
— Tony Hoare Primary source“I realised that both verification and testing were using the same technology—assertions—on a common goal of improving software products in their speed of delivery, their quality, and their reliability.”
— Tony Hoare Primary source“Now is no time to think of what you do not have. Think of what you can do with what there is.”
— Ernest Hemingway Primary source“Good design is durable. It has nothing trendy about it that might be out of date tomorrow. This is one of the major differences between well-designed products and short-lived trivial objects for a throwaway society that can no longer be justified.”
