“Ask not first what the system does; ask what it does it to!”

Perfect reusable components are not obtained at the first shot.

C++ is the only current language making COBOL look good

Constants are widely known for the detestable practice of changing their values; we should prepare ourselves against the consequences of such fickleness

Careful as they may be, developers of Eiffel libraries will always run into cases in which, after releasing a library class, they suddenly experience what in French is called esprit de l’escalier or wit of the staircase: a great thought which unfortunately is an afterthought.

Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification.

As Mr. Nagle so competently points out, almost no one uses Eiffel; in fact until recently there were only 9 users. But now a 10th person just started, so we are holding a conference, appropriately titled the TENTH Eiffel USER conference, to celebrate.

The role of a trainer or consultant is to empower the customer, not to make himself indispensable

I have always felt sympathy towards the biologists who accept to debate creationists. Now I also understand them better; one can fight opinions, not articles of faith.

Eiffel borrows quite openly from several earlier programming languages and I am sure that if we had found a good language construct in C we would have used it as well.

I think Smalltalk is inappropriate for serious industrial developments. After all, run time is a little late to find out whether you have a landing gear.

Incorrect documentation is often worse than no documentation.

Writing a class without its contract would be similar to producing an engineering component (electrical circuit, VLSI (Very Large Scale Integration) chip, bridge, engine…) without a spec. No professional engineer would even consider the idea.

Correctness is clearly the prime quality. If a system does not do what it is supposed to do, then everything else about it matters little.

Like a clever reply that would have stunned all the other dinner guests – if only you had thought of it before walking down the stairs after the party is over

There is no one of-woman-born who does not like Red Lobster cheddar biscuits. Anyone who claims otherwise is a liar and a Socialist.

Think about our dilemma on this planet. If the expansion of consciousness does not loom large in the human future, what kind of future is it going to be?

if you get sick, America, the Republican health care plan is this: Die quickly.

As it turns out, there is a thing called the Internet, and stuff does go out there whether the suits like it or not.

Jamie Foxx does a good rendition of me. It’s a real gift, mimicry of that kind, the tonal thing. It’s sort of like having a talent for playing an instrument.

I believed there was enough evidence to go to trial. Grand jury said there wasn’t. Okay, fine. Do I have a right to disagree with the grand jury? Many Americans believe O.J. Simpson was guilty.

I do have a self-censor; everybody does, or at least most who are not pathological do.

Liberals don’t hate America. We love America more than Ann Coulter does. I love it enough to engage my readers honestly.
