Let me take this occasion to point out that John Gustafson
and William Kahan have agreed to participate in
The Great Debate: The End of Error?
at the upcoming ARITH23 conference on July 12, in Santa Clara:

I will be the "moderator", if that is possible. It may be more
appropriate to think of this as the computer arithmetic
version of the movie "Rocky", so "referee" may be a better
description of my role :) .
