Yeah, you know me.
We just pushed the latest update to Ruby Science, including five new chapters.
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.
