Hi Jason! I read your "Clever Algorithms" book a couple of years ago, and I loved it. I never had a chance to thank you, but since you're here, thank you so much for writing such a fun and interesting book. I just loved it, and I'd recommend it to anyone interested in cool algorithms.
For people like me that are used to only reading the comments: You can read the book online, code is in ruby, example: tabu search for the traveling salesman problem.
I should suggest updating the code by using the python ecosystem: numpy, pandas, scikit-learn and enhacing the value book with a little of ML
If you like my style, I also have material on machine learning (the statistical sort) over at http://machinelearningmastery.com/
