In the practical world of computing, it is rather uncommon that a program, once it performs correctly and satisfactorily, remains unchanged forever.

Clearly, programming courses should teach methods of design and construction, and the selected examples should be such that a gradual development can be nicely demonstrated.

Software development is technical activity conducted by human beings.

Nevertheless, I consider OOP as an aspect of programming in the large; that is, as an aspect that logically follows programming in the small and requires sound knowledge of procedural programming.

It is evidently necessary to generate and test candidates for solutions in some systematic manner.

Usually its users discover sooner or later that their program does not deliver all the desired results, or worse, that the results requested were not the ones really needed.

Our ultimate goal is extensible programming (EP). By this, we mean the construction of hierarchies of modules, each module adding new functionality to the system.

I have never designed a language for its own sake.

Many people tend to look at programming styles and languages like religions: if you belong to one, you cannot belong to others. But this analogy is another fallacy.

But active programming consists of the design of new programs, rather than contemplation of old programs.

Experience shows that the success of a programming course critically depends on the choice of these examples.

My duty as a teacher is to train, educate future programmers.

The idea that one might derive satisfaction from his or her successful work, because that work is ingenious, beautiful, or just pleasing, has become ridiculed.

Indeed, the woes of Software Engineering are not due to lack of tools, or proper management, but largely due to lack of sufficient technical competence.

Program construction consists of a sequence of refinement steps.

My being a teacher had a decisive influence on making language and systems as simple as possible so that in my teaching, I could concentrate on the essential issues of programming rather than on details of language and notation.

A good designer must rely on experience, on precise, logic thinking; and on pedantic exactness. No magic will do.

The possible solutions to a given problem emerge as the leaves of a tree, each node representing a point of deliberation and decision.

Programming is usually taught by examples.

But quality of work can be expected only through personal satisfaction, dedication and enjoyment. In our profession, precision and perfection are not a dispensible luxury, but a simple necessity.

In the practical world of computing, it is rather uncommon that a program, once it performs correctly and satisfactorily, remains unchanged forever.

Yet, I am convinced that there is a need for high quality software, and the time will come when it will be recognized that it is worth investing effort in its development and in using a careful, structured approach based on safe, structured languages.

Software is getting slower more rapidly than hardware becomes faster.

Johnny Winter is one of the best blues players in the world. He's very underrated.

The world is... the natural setting of, and field for, all my thoughts and all my explicit perceptions. Truth does not inhabit only the inner man, or more accurately, there is no inner man, man is in the world, and only in the world does he know himself.

You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand.

Well concerning the world records that I did, I think it helps a lot to me, yeah. I think it's a very individual thing because I heard some people say, like, oh I don't like it at all. But I definitely, for me it really made a big difference.

Christians should never fail to sense the operation of an angelic glory. It forever eclipses the world of demonic powers, as the sun does a candle's light.

I do believe there are leaders who are like lightning and they come along and they lead. The Lincolns of the world, the Alexander the Greats, they do exist. They have existed.

The people of England are the most enthusiastic in the world.

You've got to realize. In the western world, regardless of what color you are, what title the music is, it's all played by the same notes.

Most fathers don't see the war within the daughter, her struggles with conflicting images of the idealized and flawed father, her temptation both to retreat to Daddy's lap and protection and to push out of his embrace to that of beau and the world beyond home.

Scientific corporations might well become almost independent states and be enabled to undertake their largest experiments without consulting the outside world - a world which would be less and less able to judge what the experiments were about.

To see a world in a grain of sand and heaven in a wild flower Hold infinity in the palms of your hand and eternity in an hour.

The painter... does not fit the paints to the world. He most certainly does not fit the world to himself. He fits himself to the paint. The self is the servant who bears the paintbox and its inherited contents.

The world has fundamentally changed. It fundamentally changed when the Berlin Wall came down and the 'evil empire' ceased to exist. We are engaged around the world whether we like it or not.

I think having eight kids evens things out a bit. You learn about the world; you learn about the world; you learn you've got to get along. We're all - if anything - very adjustable.

The bravest sight in the world is to see a great man struggling against adversity.

It's about how to bring together the seemingly contradictory aspects of the memorial, which is about a tragedy and how it changed the world, but also about creating a vital and beautiful city of the 21st century.

The world remains ever the same.

Education is a private matter between the person and the world of knowledge and experience, and has little to do with school or college.

A true critic ought to dwell upon excellencies rather than imperfections, to discover the concealed beauties of a writer, and communicate to the world such things as are worth their observation.

I still feel that a movie has to attempt to say something - even if it fails miserably. But I've sort of given up on believing that I'm going to change the world with every film I choose to act in.

In their greatest hour of need, the world failed the people of Rwanda.

90 percent of my time is spent on 10 percent of the world.

I was stuck at home in bed with me and got more and more involved with the Internet. I used it to keep in contact with friends and to make sure I was up to date with everything that was going on in the world.

There is one thing higher than Royalty: and that is religion, which causes us to leave the world, and seek God.

When I was starting to get noticed as an actor in the 1970s for something other than the third cowboy on the right who ended up dying in every movie or episode, Burt Reynolds was the biggest star in the world.

Without art, the crudeness of reality would make the world unbearable.
