Abstraction in Software Design

Abstractions are the most fundamental elements and the most important tenet of Software Design. Yet, most of us can't explain it, or can't recognize good from bad abstractions. In this video I attempt to explain how to design abstractions as well as how to recognize weak and strong abstractions and when to even attempt to abstract.
