Quotes

A quotation from Yan-Xi-Shan (unrelated to Yan-Xi Liu)

Symmetry is a complexity reducing concept (co-routines include sub-routines); seek it everywhere.

By Alan J. Perlis, Epigrams on Programming, ACM's SIGPLAN journal, 1982.

(April 1, 1922 - February 7, 1990: He was born in Pittsburgh, Pennsylvania. He was the first recipient of the Turing Award, in 1966. He was the first head of the Computer Science Department of Carnegie Mellon University. Alan Perlis was a professor of Computer Science at Yale University. )
