Getting Started with Fluidinfo
Imagine a public storage system that has a place online for structured data about everything that exists - or that could exist. This book introduces Fluidinfo, a system that enables you to store information about anything, real or imaginary, in any digital form. You'll learn how to organize and search for data, and decide who can use, modify, and extend what you've contributed.

This guide demonstrates Fluidinfo's potential to create social data, with facilities that encourage users and applications to share, remix, and reuse data in ways they may not have anticipated. You'll learn how to use tools for reading and writing data, and how to use Fluidinfo in your own applications by working with its writable API and simple query language. more »
Learning jQuery Deferreds
Orchestrating asynchronous function calls in JavaScript often leads to callback hell, but there is a reliable way to avoid this painful state of affairs. With this concise and simple guide, you'll learn how to use jQuery deferreds and promises, an elegant approach for managing asynchronous calls in both client and server applications.

This book contains 18 examples that use deferreds to solve progressively challenging real-world programming problems, along with 75 stimulating puzzles (and their solutions) that will help you understand how and when to use deferreds. You'll learn new tricks in a fun way, and become immersed in the practice of event-based programming. more »
