DESCRIPTION:It is common for complicated systems which work perfectly in a
  test deployment to fail horribly in a production one\, and a large propor
 tion of the time needed to fix such failures is spent determining which as
 pects of the production environment were inadequately captured by the test
  one. Experienced programmers are fully aware of this difficulty\, and so 
 the vast majority of realistic systems include some mechanisms to simplify
  it. In particular\, they almost always include some ad-hoc\, manually-ins
 erted logging of ``interesting'' events. In this talklet\, I will argue th
 at this kind of logging should instead be systematic and automated\, and s
 uggest some (very\, very preliminary) ideas for arranging this.
