Hi, people:

This is the new errata sheet.  There are somenew real errors, a whole lot
of niddly grammatical errors, and a few explanatory sentences.  I am trying
desperately to get Wiley to print a corrected version of the book.  To
help the process, send your thoughts on the matter to my editor:

way of shuffling, using random (n-1) instead of random (i) so
that every position is swapped with a random position, does not
give a random distribution.
