Strawberry  picking now needs me every day, as opposed  to less days!
But  Alisi  and Joe are letting  me just work half-days  because  I'm
writing a book. 

My chapter  one is short, but kicks off with a very dense common lisp
function that spawns hopfield net closures.  The dense code serves  a
few purposes. Latently, the closures are useable and useful in common
lisp  (and  via ecl, C).  This code is also  my own definition  of  a
binary   Hopfield  network  with  rectified   quadratic   activation,
connected  from Krotov and Hopfield 2016. However, the logic and code
itself is not very desirable to play with changing. 

Anyway, I did the deep-learning-doing-XOR  thing.  Participation  and
criticism requested! 

!  I didn't write the appendix  yet, wherein I intend to explain asdf
(basically put my cl-binry-hop/  gopher directory into ~/common-lisp/
in order to use it like chapter 1).
