Expert Oracle Exadata ReviewThis is a fantastic technical tome on all things Exadata. Outstanding coverage includes intro of the technology, hardware configurations, administration tasks, performance monitoring and diagnostics, wait events, backup & recovery, and application SQL tuning. Quite easily one of the two best books I've ever read regarding any Oracle technology (The other being Guy Harrison's Oracle Performance Survival Guide). I've met some of the book's authors over the years at various Oracle events (e.g. Hotsos) and thus knew these guys were top notch. But this book still totally blew me away even expecting it to be great knowing who it was coming from. I've been doing Oracle databases for over 20 years, written nine book myself, taught for Oracle Education, and worked extensively with all things Oracle. In fact I'm an Oracle ACE. So I know a good book when I see one - and this book is tops. You will not be disappointed - worth every penny.Expert Oracle Exadata Overview
Throughout history, advances in technology have come in spurts. A single great idea can often spur rapid change as the idea takes hold and is propagated, often in totally unexpected directions. Exadata embodies such a change in how we think about and manage relational databases. The key change lies in the concept of offloading SQL processing to the storage layer. That concept is a huge win, and its implementation in the form of Exadata is truly a game changer. Expert Oracle Exadata will give you a look under the covers at how the combination of hardware and software that comprise Exadata actually work. Authors Kerry Osborne, Randy Johnson, and Tanel Põder share their real-world experience, gained through multiple Exadata implementations with the goal of opening up the internals of the Exadata platform. This book is intended for readers who want to understand what makes the platform tick and for whom-"how" it does what it is does is as important as what it does. By being exposed to the features that are unique to Exadata, you will gain an understanding of the mechanics that will allow you to fully benefitfrom the advantages that the platform provides.

The ActionScript 3.0 Quick Reference Guide: For Developers and Designers Using Flash: For Developers and Designers Using Flash CS4 Professional (Adobe Developer Library) ReviewI was browsing at Borders at Park Ave and 57th, where they had exactly one copy of this. I'd heard of this book but hadn't seen it yet--it was announced over the summer but O'Reilly kept delaying publication so the book could be current with Flash CS4. I looked up a few items in the ToC and index, and went straight to the checkout queue. I had to have this book right away! even if Amazon could sell it to me cheaper!
Okay, why is the book good? I've spent more time with it now. I'll give you my three biggest reasons:
1) It's readable. It really is. It's friendly and accessible. Did you ever enjoy those juvenile histories and biographies and How-and-Why science books that started out with something like, "Hi! This is a fun book, and we're going to take you on a fun journey, step-by-step. This is a great subject to be interested in! Aren't you happy? Well, we are!!!"?
Well, did you like books like that? I did, and I've always resented scholarly and technical books that didn't introduce themselves along those lines. So many of them are written like resentful documentation: "Go away. We hate you. This is only for ugly, squirrelly, socially backward people like US."
This book is overtly addressed to users of ActionScript 1.0 and 2.0, and those already using 3.0; to artists, designers, and developers of all stripes. It's all-inclusive. Like Rich Shupe's Learning ActionScript 3.0, it has a friendly, hand-holding attitude that goes through the length of the book.
2) A personal obsession: this book has a good section on how to write XML loaders that use HTML. This is a very poorly documented area of Flash. The ActionScript 3.0 Cookbook had a little bit on it, but the explanation was hard to follow and the code was buggy.
3) Another personal interest: SWF loaders and unloaders. This is the first book I've seen that tells you how to unload both the thing loaded and the "event listener" that keeps sitting there, using up processor time and space.
The book is also current with the less traditional Flash-related technologies, such as FlashDevelop and Flex.The ActionScript 3.0 Quick Reference Guide: For Developers and Designers Using Flash: For Developers and Designers Using Flash CS4 Professional (Adobe Developer Library) Overview
"No matter what your background, the pages that follow will provide you with some excellent knowledge, insight, and even a little bit of wisdom in the realm of Flash and ActionScript. Happy learning!" -- Branden Hall, from the Foreword Written by Flash insiders with extensive knowledge of the technology, this guide is designed specifically to help Flash designers and developers make the leap from ActionScript 2.0 to the new object-oriented ActionScript 3.0 quickly and painlessly. Formatted so you can find any topic easily, ActionScript 3.0 Quick Reference Guide explains:

Object-oriented programming (OOP) concepts, such as packages and classes
ActionScript 3.0 features and player enhancements that improve performance
Workflow differences between ActionScript 2.0 and ActionScript 3.0 including tools, code editing, component sets, and image and font rendering
Where did it go? A guide to help you find familiar features in ActionScript 3.0, such as global functions, operators, properties, and statements
How do I? Step-by-step solutions for performing tasks with ActionScript 3.0, including input, sound, video, display, events, text, and more

Also included are overviews of Flash and ActionScript features and workflows. ActionScript 3.0 is a huge upgrade to Flash's programming language -- and this guide helps you upgrade your skills to match it.
