Hi, I've remembered one of the challenges on: refactoring old programs. It was one of the links setting aside in my memory collecting dust. And i thought, it would be a nice quiz to cut our red teeths on. The link is: http://www.mindspring.com/~alanh/refactoring/challenge.html The idea is not new in ruby-quiz, but its a combination of http://www.rubyquiz.com/quiz26.html & http://www.rubyquiz.com/quiz31.html Even if it does not qualify as a quiz, i hope someone enjoy it as a part time excersize. Regards Ala'a M.
