Peter Armstrong has put out an excellent PDF on integrating Adobe Flex and Ruby on Rails. He had planned to release the book in print using Lulu, however, Manning Publications has picked it up and will be publishing it for him. I am proud to say that I (Robert Dempsey) have been chosen as a reviewer for the print book. At ADS we have been looking more and more info Flex as an alternative to AJAX. Peter uses FlexibleRails to show how this combination makes for powerful, beautiful looking, browser loving web applications.

While not being about Peter’s awesome book, Ajaxian has posted a link to the PDF version of the Adobe Integrated Runtime (AIR) for JavaScript Developers Pocket Guide (Amazon). Grab it while its hot -> http://ajaxian.com/archives/adobe-air-free-book-download
