I saw a really great post on the Freakonomics blog talking about how hidden connections almost sunk Chicago. I've seen situations like this all too often during my career. At least in the software world, we can try to prevent this by developing modules that are more loosely coupled. Of...

Do we really need ServiceInterface, ServiceImpl, DaoInterface, and DaoImpl? Or can we just say the EntityManager is the DAO, and blow away a generally unnecessary layer? On CRUD apps, 9x out of 10, the service layer is merely a pass-through to the DAO. Is there time to...
