Guidelines for better Ruby and Rails Code:

1.) All OO Rules including this guideline should be treated like guidelines and not as rules / laws

2.) Use class-level interfaces only for building objects, Refactoring specific

3.) Use Dependency Injection for objects which need collaborators or configuration

4.) Immutability - use ValueObjects, or Objects without a public interface for changing its instance vars (mutable state will be your dead)

5.) Know and respect Sandi's Rules:

Classes can be no longer than one hundred lines of code.
Methods can be no longer than five lines of code.
Pass no more than four parameters into a method. Hash options are parameters.
Controllers can instantiate only one object. Therefore, views can only know about one instance variable and views should only send messages to that object

6.) Convenience vs Explicitness

7.) Relationship

"has-a" -> Person has a Car -> Composition
"acts like" -> Mixin
"is-a" -> Inheritance
