CouchDB: The Definitive Guide: Time to Relax (Animal Guide) ReviewThe book does a good job covering the features that make CouchDB such an exciting technology - schema-free document-based storage, REST API, MapReduce, powerful replication, embedded applications, etc. I'd recommend it for developers with a good background in web programming that are looking for a new way of building and scaling applications. Database administrators will also benefit from its coverage of replication and sharding.
The organization and editing are, unfortunately, not so good. Topics seem strangely ordered, cross references are awkward, and chapters alternate between repeating material unnecessarily and assuming knowledge of material that has not yet been covered. I'd guess this comes from merging the work of three authors, but O'Reilly usually does a better job cleaning up the inevitable collisions.
That aside, this is still a good introduction to the subject, and will give you enough background to start exploring CouchDB without getting (too) lost. Well worth a place on your NoSQL bookshelf.CouchDB: The Definitive Guide: Time to Relax (Animal Guide) Overview
Three of CouchDB's creators show you how to use this document-oriented database as a standalone application framework or with high-volume, distributed applications. With its simple model for storing, processing, and accessing data, CouchDB is ideal for web applications that handle huge amounts of loosely structured data. That alone would stretch the limits of a relational database, yet CouchDB offers an open source solution that's reliable, scales easily, and responds quickly.

CouchDB works with self-contained data that has loose or ad-hoc connections. It's a model that fits many real-world items, such as contacts, invoices, and receipts, but you'll discover that this database can easily handle data of any kind. With this book, you'll learn how to work with CouchDB through its RESTful web interface, and become familiar with key features such as simple document CRUD (create, read, update, delete), advanced MapReduce, deployment tuning, and more.

Understand the basics of document-oriented storage and manipulation
Interact with CouchDB entirely though HTTP using its RESTful interface
Model data as self-contained JSON documents
Handle evolving data schemas naturally
Query and aggregate data in CouchDB using MapReduce views
Replicate data between nodes
Tune CouchDB for increased performance and reliability

The Definitive Guide to Lift: A Scala-Based Web Framework (Expert's Voice in Open Source) ReviewFive stars for the authors, and zero star (if that was possible) for the publisher.
This book is a rip-off. The authors have done a great work but the publisher has provided no value except putting the book on paper. No index! The appendices mentionned in the text are missing from the book!
Also, the title is a blatant lie, 'The Definitive Guide to Lift: A Scala-based Web Framework' is just a snapshot of an ongoing work. If Lift seems mostly stable, the book needs more work. Nothing definitive here even if the authors have done a great work.
The up to date pdf is available on the web with a more modest title "exploring lift". This is the first apress book I bought and probably the last. Shame on apress.
You need to know scala to read the either the book or the pdf. Lift seems a great framework.The Definitive Guide to Lift: A Scala-Based Web Framework (Expert's Voice in Open Source) OverviewLift is a Scala based Web application framework, for being productive and useful with Scala. It takes Scala out of academia, and puts it in the real world, making Scala quite pragmatic as this functional programming language continues to grow.Exploring Lift will be the first Lift book to market, and endorsed by the Lift Founder/Lead David Pollak.
