“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.”

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

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

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.

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

A holiday is when you celebrate something that’s all finished up.

We rarely get a definitive look at just how complicated and sometimes dangerous their everyday lives were. In fact,

When reading about what may be described as the lesser celebrated heroic figures of the Harlem Renaissance,

The singular historic moment millions now celebrate could have been tragically lost to guerrilla decontextualization.
