Overview
Asynchronous callback nightmares stalk JavaScript developers, both in their traditional hunting grounds in the browser and in their new territory on the server. The smart folks at jQuery have figured out better ways to deal with these terrors, building a new approach called deferreds into their library. It works on both the client (of course!) and on the server (for the Node folks). Callbacks are added to Deferred objects corresponding to outstanding asynchronous calls. When the result of the asynchronous tasks become known, the callbacks are run. As a distinct object, with simple formal semantics for handling future results, Deferreds provide concise and flexible expressive power to programmers working with asynchronous events.

Author Information
Terry hates computers but loves programming; Fluidinfo is a natural consequence of these conflicting passions. Terry was previously a postdoc in Zoology at the University of Cambridge (2004-07) where he spent time helping the WHO design part of the human influenza vaccine. He was also a part-time professor in CS at the Universitat de Pompeu Fabra (2005-06), CTO of Eatoni Ergonomics in New York (2000-04), a postdoc in Cognitive Science at UCSD (1998-99), CEO of Teclata in Barcelona (1996-98), and a postdoc and graduate fellow at the Santa Fe Institute (1992-96). He has a Ph.D. in CS from the University of New Mexico, an M.Math from the University of Waterloo, and a B.Sc. in CS from Sydney University. Nicholas is a classically trained musician, philosophy graduate, teacher, writer and software developer. He's been programming since 1984 when he taught himself BBC Basic at junior school. He currently works at Fluidinfo where he gets to do all sorts of fun and exciting things like trying to change the world of linked data. Prior to working as a developer Nicholas was a senior teacher in an inner-city state secondary school in the UK. He has extensive experience working with students of all ages and abilities and still indulges his passion for teaching and learning by helping to run the London Python Code Dojo. A graduate of the Royal College of Music (Nicholas used to play professionally) he also has an MA in Philosophy of Education and financed his MSc in Computing by writing reviews and articles for the UK edition of Computer Shopper.
