apresentação interessante: construindo Rich Interactive Applications
muitíssimo interessante essa apresentação. achei aqui. bom material para quem está se envolvendo com RIA e se interessa tanto pela parte visual quanto pela arquitetura
Josh Holmes has posted a set of slides and detailed explanation for a talk he and James Ward did about architecting rich Internet applications. The post and the slides are well worth a read. One of the things that has been both fun and terrifying to watch as Flex evolved was the increasing complexity of the applications. And with both Flash and Silverlight you have a lot of visual options at your disposal so it’s easy to focus on flashy visuals without architecting both under the hood and the overall user experience.
