[Haskell-cafe] SPJ's Venn diagram on type-correctness

Hi all, Sometime in the past, I came across a presentation from SPJ in which he showed a Venn diagram showing "programs that compile" and "programs that are correct". Unfortunately, I cannot remember the exact wording and I'm unable to find the slides/talk on google/youtube. Does anyone remember the exact details of the diagram? Or the title of the talk? Is there still a link to it? Thanks, Mathijs
