Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly
encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with
newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth
of experience available to Ruby developers for their own daily work."
—Steve Metsker, Managing Consultant with Dominion Digital, Inc.
This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting
to overly technical explanations. Written in a precise, yet almost informal style, this book covers
enough ground that even those without prior exposure to design patterns will soon feel confident
applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject
into such an engaging and even occasionally humorous read.

This book is a practical guide for developers and information technology managers. It is focused on conveying what elements make up a portal and how to construct these elements using the Microsoft development platform. It is a combination of introductions to key concepts, suggestions for portal planning, and limited detailed technical instruction by way of examples that relate to all the main portal elements. Most chapters describe what to build and then show how to build it.

The most important section for managers is the first five chapters. These chapters address the portal from the perspective of a user and provide valuable background that can help managers form reasonable project expectations. The focus is not on individual products and features. Indeed, portals with the functionality described here could be implemented with a number of different technologies and products, and these are introduced in the second part of the book.

Developers will spend more time with the remainder of the book to understand how to fill the gap between products and where each portal service belongs. They will want to review the early chapters to understand the vision for a .NET portal and to ensure that the IT manager doesn't know something that they don't. These later chapters do not attempt to restate the vast amount of information in help files and product documentation for the products used in our examples. Rather, our goal is to create a higher-level overview that encompasses multiple products and puts each product and feature in its proper place. We also highlight best practices and hints that are not found in the product documentation but can save many hours of work or frustration.

There are no prerequisites for grasping the material in this book, as it explains the anatomy of a portal from the ground up. Our goals are to provide a compelling vision for portals that can be applied to your business requirements and to explain in detail how this vision maps to the Microsoft .NET Framework and web services.

Web mining aims to discover useful information or knowledge from the Web hyperlink structure, page content and usage log. Based on the primary kind of data used in the mining process, Web mining tasks are categorized into three main types: Web structure mining, Web content mining and Web usage mining. The goal of this book is to present these tasks, and their essential algorithms. It is written for advanced undergraduate students, graduate students, researchers and development professionals in the field. No prior knowledge of data mining or statistics is assumed. In fact, the book covers the essential topics of data mining as well.
