Hello Flex 4 Review

Average Reviews:

(More customer reviews)If you've been thinking about Flex, or know someone who wants to get a basic understanding in a very short amount of time you'll want to check out Hello Flex 4 by Peter Armstrong.
This short 234 paged book is an action packed light hearted casual read for programmers who are curious about Flex but may not be at the point where they want to invest a ton of time until they get a general understanding of how it works and if it's a right match for them.
The tone of the book is laid back, and Peter doesn't bore you with exhaustive detail, while at the same time there are small cartoons to keep it fun. Structure wise the approach uses sessions/labs to demonstrate concepts, and these sessions provide real working code. As each session progresses it builds upon the last - leading up to a full blown application.
So the examples are small and easy to understand, while at the same time being practical that you could then apply for you own purposes. In the very last chapter he's a bit gutsy by incorporating the Cairngorm MVC framework as part of the lab... Cairngorm is a pretty heavy duty topic, so my reaction was would using it in a introductory book be good idea?
Well, if you really wanted to get an honest quick feel if Flex is right for you, you might as well get a taste of what a framework driven Flex application would look like. To my surprise though, Peter pulls it off, and makes Cairngorm digestible (especially considering the reader may not have any prior Flex/ActionScript exposure) by keeping it simple, to the point, and clear about what it's role is in a Flex application.
So overall, for a quick read and low price, this is a great way to jumpstart your Flex skills. There's currently a promotion where you can get the book for a measly $10 by using discount code hf410 (I think it ends at the end of the month).

Flex 4 is an open-source tool that allows developers to easily add life to web applications with dynamic user features, colorful transitions, and eye-catching animations. Flex also provides powerful data handling for industrial-strength applications.

We think it should be just as much fun to learn Flex as it is to use it. And we know that fun learning gets better results. Hello! Flex 4 demonstrates how to get started without getting bogged down in technical detail or academic edge cases. In this book, User Friendly cartoon characters offer commentary and snide side comments, as the book moves quickly from Hello World into practical techniques. Each one is illustrated with a hands-on example. Along the way, readers will build a unique Flex application that mashes Yahoo Maps with Twitter to keep track of friends.
