Designer, implementor, user, writer A Fragment by Donald Knuth dl.acm.org Thus, I came to the conclusion that the designer of a new system must not only be the implementor and the first large-scale user; the designer should also write the first user manual. The separation of any of these four components would have hurt TeX significantly. If I had not participated fully in all these activities, literally hundreds of improvements would never have been made, because I would never have thought of them or perceived why they were important.

Fucking up the world City Hall by Rafael Moneo, Logroño, La Rioja, Spain. Alexander : At least my experience tells me, that when a group of different people set out to try and find out what is harmonious, what feels most comfortable in such and such a situation, their opinions about it will tend to converge, if they are mocking up full-scale, real stuff. Of course, if they're making sketches or throwing out ideas, they won't agree. But if you start making the real thing, one tends to reach agreement. My only concern is to produce that kind of harmony. The thing that strikes me about your friend's building – if I understood you correctly – is that somehow in some intentional way it is not harmonious. That is, Moneo intentionally wants to produce an effect of disharmony. Maybe even of incongruity. Eisenman: That is correct. Eisenman: I find that incomprehensible. I find it very irresponsible. I find it nutty. I feel sorry for the man. I also feel incredibly angry because he is fucking up the world.
