Title: Data Mining with Microsoft SQL Server 2000 Technical Reference
Publisher: Microsoft Press
Authors: Claude Seidman
Rating: 5/5
Customer opinion - 5 stars out of 5
Extremely useful

I always look for Seidman's contributions in SQL magazines and at conferences since he always has something interesting and innovative to say that is fuelled by his depth of knowledge of the subject. What's more he has a great knack of presenting complicated (and sometimes, let's face it, not very exciting) concepts in a way that makes them easy to understand and in contexts that anyone can relate to. In particular his style is reminiscient of Roger Sessions (Com+ and the Battle for the Middle Tier, etc) minus the cynicism but with equal enthusiasm. No book can be all things to all people, but this is an excellent introduction to the world of Data mining and the power behind SQL200's implementation of it. I would recommend it to anyone looking to discover those hidden trends and patterns in their data, exploit them and become their CFO's best friend.

generally good content but very badly edited

A potentially excellent book on the subject marred by: too much redundant and repetitive material, poor organization of content, and absolutely atrocious editing (very annoying!).

My favorite Perl book ever!

This book is not a good way to learn Perl, but if you're already up and running it will answer any weird question you can possibly com up with e.g. "How do you build an array of links from a page on the web" Answer: use LWP and HTML::LinkExtor.
The Q&A format is fabulous and Christiansen provides all kinds of expert insight.

Deceptively good book

I need to create a 3d math library for a project I was working on and wanted to take a look at some book on the subject. This one looked like one of the 14 year old 'how to make a video game' type books and I wasn't expecting much, however I was pleasantly suprised by the depth of the 3d mathematics in the book. As an example i was unclear about how to calculate the inverse matrix correctly for an n-dimension matrix and the book goes over calculating adjucts and determinats, and inverses for a n-dimensional matrix both supplying the general math and some C code. The code i didn't find helpful, simply because I coding in the python c api and not straight c, however it could be helpful to someone writing in C.I would recommend this book to anyone looking to brush up on quaternions, eulers, matrices, and vectors as this book is simple and to the point. I think the author did a great job balancing the complexty of the math with simplicity in the book's text. The book goes over what is really the essentials of any 3d math library.
