One-way Compression Function/the Merkle-damg%C3%A5rd Construction

Famous quotes containing the words compression, function and/or construction:

    Do they [the publishers of Murphy] not understand that if the book is slightly obscure it is because it is a compression and that to compress it further can only make it more obscure?
    Samuel Beckett (1906–1989)

    As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.
    Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)

    There’s no art
    To find the mind’s construction in the face.
    William Shakespeare (1564–1616)
