Did a presentation about Groovy on Google's App Engine at GTUG Stockholm last thursday. Had a great evening as expected.

Johan Burell (@Burre83) demoed his api and client implementation of a MIDI api for the android. The live "DJ on the Android" demo was cool even though it was impossible to actually see what he did as he used his own phone instead of the emulator during the demo. 

Mikael Kindborg (@divineprog) presented on Google Closure, a new library for JS development which comes with what seems to be a really effective JavaScript Optimizer. There was even some more Android to be had when he demoed his JS Android Client that receives JavaScript over a socket and runs it on the device. Was kinda cool when a guy on the first row held up the Mikaels Android and we could se how the ui on the phone changed as Mikael recoded it live on his computer. I have a hard time seeing the practical applications for this but it's a cool demo non the less.

I focused on how to leverage Groovy on App Engine using Gaelyk as Grails IMHO isn't really worth the effort right now (on GAE). The environment I used was SpringSource Tool Suite (Groovy support) and the Google App Engine Plugin for Eclipse.

Presentation and examples: on Github as well as on GTUG Stockholm:s page
