If we have nils for taggable_id in tag_items, then when I go to 
  http://localhost:3000/collection_items/b 
the server log looks OK, like this (hey I only put this in for comparison, 
no need to read it (yet?)), skip on below


~/01rails/social-museum 0 $ rails s

OK Ive created a Subscription model, and expect somewhat to hang stuff off there

class Subscription < ActiveRecord::Base
  belongs_to :user
  belongs_to :page
end

There is an indexed id in the table cause I created it thus

class CreateSubscriptionsTable < ActiveRecord::Migration

# so I want to dry up this kind of method, which occurs only four times, but since I anticipate using this construct a few more times, and page.rb is looking long, the effort of metaprogramming seems worthwhile

# with I guess moving the defn of spec attr acessor out into an included module

# so here is the code to dry, shown for categories

def categories=(c)
    if history.last.try(:new_record?)
      history.last.categories = c
    else

For someone who denies being able to see into the future, Sutherland has a remarkable record of helping to create it. In the late 1960s, the Bell Helicopter Company used low-light cameras to help pilots land at night, and devised a system which turned the camera when the pilot turned his head. Sutherland, by then a professor at the University of Utah, wondered why the camera couldn’t be replaced with a computer. With the assistance of Bob Sproull, he created a gizmo — with the wonderful name The Sword of Damocles — which let a user peer into a computer-generated graphical display which, like Bell’s remote camera, adjusted automatically to head turns.
