Developer practices for traditional and agile Java development are well understood and documented. But dynamic languages (Groovy, Ruby, and others) change the ground rules. Many of the common practices, refactoring techniques, and design patterns we have been taught either no longer apply or should be applied differently and some new techniques also come into play. In this talk, we'll relearn practices needed for dynamic languages. Along the way we will look at typing, design patterns,
refactoring, functional style, SOLID principles revisited and more.
