For developers who want to improve their art there's no shortage of published, promoted and proclaimed principles they can choose from to shape their style and craft their code. Whether it's the alphabet soup of SOLID principles or old school classics like Information Hiding and the Separation of Concerns, there's a lot of advice out there. Some of it even makes sense.
