I realize I haven't been blogging a lot about what I've been up to in the last few months so thought I'd better get a post out and share some of those things with you.

Cocoon P2P

The open source Cocoon P2P library has been released and got Dirk Eismann on board as a contributor after speaking at FFK11 in April. With his help we were able to take it from more of a proof of concept to a solid solution for doing local IP multicast with the Flash Player (no server required).

We have great support for device discovery, messaging and object-replication. Reworking the video streaming and fixing some bugs on the accelerometer support is still on my todo list for the very near future.

HTML5 Solutions

I've had the pleasure to work on a book called "HTML5 Solutions: Essential Techniques for HTML5 Developers" with fellow authors Marco Casario, Charles Brown, Nathalie Wormser and Cyril Hanquez.

My contribution to the book is on using the Geolocation API - which, if you haven't already tried it - is one of the most exciting features that is starting to become widely available with HTML5.

It turned out - in my humble opinion - to be a very good publication and should be shipping soon. I can't wait to get hold of my author copies and hear reader feedback when it hits the stores.

Mobile Development with Flash video training

Together with Joseph Labrecque I've recorded a video training title for Peachpit called "Mobile Development with Adobe Flash Professional CS5.5 and Flash Builder 4.5: Learn by Video" that is now available for pre-order.

We cover developing for Google Android and Apple iOS with Adobe AIR, ActionScript and the Flex framework from the very start of setting up your application, to using various APIs, debugging and finally submitting it to the marketplace and app store.

I had a great time recording this title in Graz, Austria with the nice folks at video2brain.

Mobile application development

I've been playing around with different mobile platforms - releasing a couple of applications for Window Phone 7, Google Android and Apple iOS as well as the BlackBerry PlayBook.

VAT validator on WP7 and Android

A while back I was giving the opportunity to do some development on Windows Phone 7 and have to admit it was a very nice experience and a solid development platform. Most of all the app submission and approval process was incredible, consistently taking only 2 days and getting detailed feedback on any problems they find - the best I've seen on any curated marketplace so far.

I decided to port the VAT validator app I had built some years back for iPhone in Objective-C in C#/Silverlight and did the same on Android through the Adobe AIR runtime. Also took the opportunity to test ad integration on mobile and made paid and free ad-supported versions to compare how well they do. I hope to share some statistics soon on how that goes and what model is most suitable for developers that do utility apps.

Sanskrit Clock iPad app

I thought it was high time to explore native development on Apple iOS again and see what the app store experience is like since I last tried it in 2008. Approval time has certainly improved and in less than a week after submitted, my Sanskrit Clock iPad app made it on the store.

Not sure how many people are interested in an app like this (aside from the handful of geeky Sanskrit enthusiasts like myself) but it includes optional romanized transliteration of the numerals, a couple of different color themes and a setting to disable the screen lock so you can use it as a clock on your desk or nightstand.

TWiT Live for PlayBook

TWiT Live is my second PlayBook app that lets you watch the live stream of Leo Laporte's TWiT network shows. I plan to add support for play/pause, volume control and switching between high and low quality streams some time soon.

It doesn't look like things are slowing down for me any time soon, end of next week I'm moving to London to start my new job at Google as a Rich Media Flash Developer. If I manage to find the time I'll be delving deeper into native Android development to do some experiments with widget development and other fun stuff.

Onwards and upwards!
