Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

• Single Responsibility Principle: a class should have only a single responsibility
• Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
• Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
• Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

Growing Rails Applications in Practice

• How to use discipline, consistency and code organization to make your code grow more gently.

• As you cycle through patterns, your application is becoming a patchwork of different coding techniques.

  All those new techniques actually help, or if you are just adding layers of inderection.

• Large applications are large so what we can do is organize a codebase in a way that "scales logarithmically".
