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.
What do you have so far? If you haven't started, what ideas have you had? (And keep in mind that it may not be clear to everybody what "leen" is - natural logarithm? But that's generally written as "ln", not "In".)
