Jeremy Miller has some great posts about Mock Objects.
- Mock Objects and Stubs: The Bottle Brush of TDD
- Why and When to Use Mock Objects

Eric Wise has a great post on "Coding to Interfaces"

Ian Landsman's "4 Rules for the Practical Entrepeneur" is a must read if you're having a tough time coming up with ideas for products.
