random coincidences

-----BEGIN PGP SIGNED MESSAGE----- What are some of the more common "coincidences" and non-random correlations that ordinary random number generators (ones found in common computer languages that don't take extensive measures to be random) have? It seems that there's a lot of fuss about getting very random numbers, but unless the numbers produced by ordinary measures have very obvious coincidences, maybe it's a big fuss about nothing...? - -sq -----BEGIN PGP SIGNATURE----- Version: 2.6 iQCVAwUBMD12u1IP+Y8TPTdtAQECmwP/UTLcmOL1sKvOrtO7XcE5mNpr5gjou/Ht kWqIbobOroIsW3YtbL/KbdFmxBhPr9SrynYc76vlqRXG0vai5xOmqRdMyCXs+67U qWWRxlJRhEgbdGNaH2YgSU7MlEIGq64oEWW439wbABG+TMQtV225gzhOUsCEM9qg 3Bun1zOnJIc= =xhWT -----END PGP SIGNATURE-----
