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:
“Poets ... are the only people to whom love is not only a crucial, but an indispensable experience, which entitles them to mistake it for a universal one.”
