Recently I was lucky enough to participate in the authoring of a book on JavaScript development in AIR with Mike Chambers, Kevin Hoyt, and Dragos Georgita. What has been great about this book is how well it has been received by the community and the fact that you could download a PDF copy of it for free (you can still purchase a hard copy as well at Amazon). What wasn’t great, was that it was only in English.
Over the past few months, Mike Chambers has been working on a solution to this problem, and what he has come up with is going to be an amazing resource. The site is called toString.org and encourages developers to submit translations to the site for publishing. Mike describes the site as:
…a site that hosts books about Rich Internet Applications, with a focus on book that leverage the Adobe RIA Technology Platform (Adobe Flash Player, Adobe AIR, Adobe Flex).
Currently there are two books on the site, both the Flex and the JavaScript pocketguides for AIR development. There are already a few translations as well. Mike is not done with the site yet as well and says that many new features are coming soon, including offline support through an AIR application, REST APIs, and diffing capability for reviewing changes between updates.
