When Not to Use Object-Oriented Techniques

Object-oriented Ruby is a hot topic in the Rails world and beyond, but it
is not always the appropriate solution.

In this talk I discuss various OO techniques, when to use them, and when
a simpler pattern exists in the functional, declarative, or procedural
world — including, yes, the Rails framework itself. You will leave knowing
when to use an aspect instead of a decorator, a mixin instead of a
presenter, or a monoid instead of a factory.

Topics will include:

• The benefits of code coupling.
• What makes Rails so anti-OO, and why that is good.
• Testing non-object oriented code.
• Good uses of classical OO design patterns.
• How to use a continuation.
