"This book is perfect for hands-on readers, wanting to achieve specific goals without getting entangled in formal definitions by getting right to the point. Here is an analogy: a Common Kite is depicted on the front cover of the book and as the bird waiting for its prey, youll be able to analyse the situation, understand it and take a clear decision after this read."
--Mathieu Hanna, Adviso
"This book offers a deep approach to real world tasks. There is much more text than code...It is hard to fault this book except perhaps that at nearly 500 pages, it is too short! "
--Neil McNaughton, Oil IT Journal
"Data analysis using open source tools is a straightforward, well explained and practical book which does not give just a laundry list of techniques but also useful pointers in how to use them intelligently. The book...is strongly recommended."
--Manoj Rengarajan, BookPleasures.com
