I'm sure every developer wants to be able to change code with confidence and without fear. Readable and self-explanatory code is one aspect of that. Too much coupling is another major source of problems that prevent you from changing one part of the system without causing side-effects. In this talk, I'd like you to show you common sources of unnecessary coupling and offer you options to help prevent and/or break those. I'll talk about how principles like Don't Repeat Yourself and Dependency Injection can be a double-edge sword, how to detect too unnecessary dependencies and how to use the Dependency Inversion Principle to unravel some of those. And yes, I will also talk about controlling dependencies on the package level.
