This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Have you tried SproutCore and MooTools (in general, not together)?
What do you think about them?
I decided to combine both frameworks in one post in order not to create another debatable thread.
