||| Primetime for Pentiums |||

It was news in 1994 [33] when the Cypherpunks broke the 429-bit key of a
challenge message ("the words are squeamish ossifrage"), working over a
period of 8 months with 1500 Unix workstations distributed around the
Internet. Now it's the Pentiums' turn [34]. George Woltman, a programmer in
Florida, wrote code for Intel machines to find Mersenne primes and en-
couraged people around the world to run it. Last month a programmer in
Paris, Joel Armengaud <joe@apsydev.com>, announced that one of 18 Pentiums
he had set to searching had found the 35th Mersenne prime: 2 to the power
1,398,269 minus 1. (The 34th Mersenne prime had been found earlier this year
using a Cray supercomputer.) Thanks to Dan Kohn <dan@teledesic.com> (as
usual) for the heads-up on this story.
