Quality Matters #5 republished

I've republished the fourth instalment of the Quality Matters column on Synesis Software's website. Exceptions: The Worst Form of 'Error' Handling, Except For All The Others, which was originally published in ACCU's Overload #98, August 2010, starts a series of four articles with a taxonomic analysis of program behaviour, identifying normative and non-normative, contingent, faulted, recoverable, and practically-unrecoverable behaviour.
