Tip of the day is Coding Blocks episode 16, Design Patterns Part 2 – Oh behave!, length 63:08.
A while back Coding Blocks had a discussion on
Design Patterns from the Gang of Four book. In this episode they continue their discussion now on Behavioral Patterns; Template, Strategy and Null Object Pattern. As usual they have an in-depth discussion and share real life examples and a detailed description on each pattern.
