Instead i bought another book that was on my shopping list as well as a second, more exotic one
Programming collective intelligence
Having read rave reviews (e.g. here and here) it was a must buy for me. Especially since all the code samples are written in Python. Expect me to test the algorithms with the news data sets i hav at hand.
The algorithmic beauty of seashells
This book definitely falls into the category: Bought mainly becaus of aesthetics and haptics.
