Me too, Manchester uni was good. I have written non-trivial systems deployed in 20 different sites that have never had a bug ever. My best are usually second systems, focus on simplicity, standardisation and resist scope creep. 100% coverage with unit tests. 100% coverage with integration tests. I've written a many things with zero bugs after delivery. (and other that were never ending quality nightmares) If I am under pressure to deliver I get strict with TDD, since no time for bug fixing.
