Someone posted this awhile back. I think it was just a link to it instead of a pdf file, which, IMO, is a nice touch. ;)
Can you show me where, please? I believe you are mixing up documents. I UTFSE for the authors last name, and came up with nothing. Thus, if some one posted it already, it is as good as nothing without the information pertaining to it.
