Is it better to be a follower or a leader?

In most cases I would say the latter, but in this case…

Starting this week, I will be giving away some Flex books randomly to my list of followers (@esulliva).

Once a week I will be selecting someone from my list of followers for a copy of O’Reilly’s Flex 3 Cookbook.

Several times a week I will be selecting someone from my list of followers to send a copy of the Getting Started with Flex 3 Pocket Guide.

All followers are eligible, but you can only win once per prize (feel free to un-follow me after you win!) That means if you win the Flex 3 cookbook, you are not eligible to win a second Flex 3 cookbook, but you are fair game for any drawings for different giveaways.

I anticipate adding some other great giveaways into the mix after I exhaust my supply of books. Could be a cool t-shirt or a backpack…maybe even a copy of Flex Builder 3 Professional will make its way into the mix!

And even if you don’t win, you’ll still have the pleasure of being kept up to date on all the new resources made available through the Adobe Developer Connection, in addition to being exposed to any witty comments I may make throughout the day.

Note to winners: you will need to either DM me or email me your name, address and phone number in order for me to send out your book.

Happy following!!

New search/commenting for Adobe Flex Developer Center

Yesterday, we launched a couple of exciting new enhancements on the Adobe Developer Connection, specifically in the Flex Developer Center.

A new community-powered search is the first enhancement. The community powered search is designed to help people find the best answer to their question, no matter where the answer may reside. If the best answer is on someone’s blog in the community, that’s the answer we want to help people find. This will not replace the existing search on, but will be available as a new beta search. There is a team of Flex advisors who are adding URLs/domains to this search on an ongoing basis.

We have also added the ability for users to add comments to Flex Developer Center content. As most of you know, we’ve had commenting on Adobe Livedocs for a while. This is the next generation of commenting, in that the commenting functionality across these two different places is integrated. The intent of commenting is to gather feedback and deliver the best possible content; by integrating the commenting, and who reviews and acts on those comments we can strive to be as consistent as possible across content on Again, there is a team of Flex advisors moderating comments, and Hong Qiu and I will be moderating the Flex Developer Center comments. Note that all posted comments go live immediately, however, where there is inappropriate content, the moderators will scrub as needed. The coolest part is that authors can monitor comments on their articles by subscribing to the RSS feed (see link below) for Flex Developer Center.

You can see both of these enhancements on the Flex Developer Center: To find the new features:
• Flex community-powered search: Look in the right-nav in the Flex DC, and you will see the “Search Community-Powered Help” form field.
• Commenting: Browse to any article in the Flex Developer Center, and you will see the option to add your comment.
• Subscribe to the RSS feed for comments for the Flex Developer Center and see all comments, anytime:

We encourage you to try these new enhancements and send any feedback. The search results page that gets returned will have a link to a feedback survey at the top right of the page.

Happy searching and commenting!

ActionScript reference for RIA development

Mike Chambers and Frog Design have done an excellent job compiling an alphabetical reference for all native ActionScript APIs for the Adobe technology platform runtimes: Adobe Flash Player and Adobe AIR, as well as the Adobe Flex framework APIs.


Use this guide both as an API reference and a tool to learn about the ActionScript APIs available within the runtimes. Mike says that this document is released under a Creative Commons license (people can redistribute, edit, and print). You could probably even have the source Adobe InDesign file if you wanted it. It’ll definitely be handed out at conferences — and maybe even the on AIR Tour now crisscrossing Europe.

Shantanu Narayen and Kevin Lynch speak at Engage 2008

Engage 2008 came and went (what, you didn’t get the invite? neither did anyone I know, including me) but you can see what happened early in the day by viewing this 50-min. video of Adobe CEO Shantanu Narayen and CTO Kevin Lynch presenting in front of the audience of “key thought leaders and influencers.”


If you can’t get enough of Engage 2008, there’s aways Scoble’s shaky Qik videos to entertain you.

New Flex 3 content now available in the Flex Developer Center

With yesterday’s release of Flex 3, the Flex Developer Center is now having a bunch of new Flex 3 content. Apart from the videos that introduce some of the new Flex 3 features, you can read getting started tutorials and new articles about designing skins and styles with Creative Suite 3 and Flex Builder 3, ActionScript and .NET client-server class mappings, and how to read and write data to your Flex 3 app from ColdFusion. If you are looking for short and practical Flex 3 how-to tips, there are quite a few new cookbook posts that talk about integrating with PHP, JSP, and using the new and updated Flex 3 components. Enjoy and don’t forget to send me your feedback. Also, if you’re interested in writing a Flex 3 article for us, please let me know and I’ll work with you on it.
