For most hobbyists, even $100 is too much.  I was simply astounded at the
chutzpah of the seller--right there on the Amazon list--who was asking
nearly $1500 for a copy.

Well, I was going to point that out to my friend Ralph, but I see that
it is a different book with the same title, by one Stephen Longo, which
has been stolen.

Rather, adapted from Ralph's early course notes (he was teaching the
class at Stanford for a few years before the book was published) by
Frank da Cruz and Chris Ryland.  I know that Frank and Ralph were
friendly, so I'm not surprised that Ralph shared his notes.

No, that's an HTMLized version of the INFO file that accompanies the
original EMACS (the one written in MIT AI Lab TECO for the PDP-10).


So David, there are alternatives to the Gorin textbook.  I simply prefer
it for paedogogical reasons.
