Ruby Science: You Down with OCP?

Yeah, you know me.

We just pushed the latest update to Ruby Science, including five new chapters. Previous purchasers and Prime subscribers can grab the update on Learn.

New chapters this week discuss:

  • Using the Single Responsibility Principle to create readable, reusable classes.
  • Applying the Open/Closed Principle to reduce churn and prevent breakage while keeping objects easy to change.
  • Applying the Dependency Inversion Principle to create flexible, reusable objects.
  • Using the Law of Demeter to prevent application dependencies from becoming a tangled mess.
  • Choosing Composition Over Inheritance to make simpler, more flexible software.

The book is a work in progress, and is currently 230 pages long. Your purchase gets you access to the current release of the book, all future updates, and the companion example application.
