Universal Computer-constructor
Codd designed a self-replicating computer in the cellular automaton, based on Wang's W-machine. However, the design was so colossal that it evaded implementation until 2009, when Tim Hutton constructed an explicit configuration. There were some minor errors in Codd's design, so Hutton's implementation differs slightly, in both the configuration and the ruleset.

Famous quotes containing the word universal:
“The world still wants its poet-priest, a reconciler, who shall not trifle with Shakspeare the player, nor shall grope in graves with Swedenborg the mourner; but who shall see, speak, and act, with equal inspiration. For knowledge will brighten the sunshine; right is more beautiful than private affection; and love is compatible with universal wisdom.”
—Ralph Waldo Emerson (1803–1882)
