Misquotations are the only quotations that are never misquoted.

~Hesketh Pearson

Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots.
So far, the Universe is winning.

John Donne (1572-1631). It appears in Devotions Upon Emergent Occasions, Meditation XVII:

"All mankind is of one author, and is one volume; when one man dies, one chapter is not torn out of the book, but translated into a better language; and every chapter must be so translated...As therefore the bell that rings to a sermon, calls not upon the preacher only, but upon the congregation to come: so this bell calls us all: but how much more me, who am brought so near the door by this sickness....No man is an island, entire of itself...any man's death diminishes me, because I am involved in mankind; and therefore never send to know for whom the bell tolls; it tolls for thee."

I'll be floating like a butterfly and stinging like a bee.
Muhammad Ali

"Gentlemen, get the thing straight once and for all — the policeman isn't there to create disorder, the policeman is there to preserve disorder."

the late Mayor Richard J. Daley, Chicago, 1968
