Tonight I attended a presentation on Ruby on Rails and Adobe Flex by Rob Kainz and Derrick Heffner.

We went to the presentation right after work; it was organized by the Triangle User Experience group (an Adobe Group) and sponsored by Railinc.

Rob and Derrick founded Roadierage.com, a website for the music industry. Rob has been developing the website using a combination of Ruby on Rails and Adobe Flex.

In the presentation Rob spoke about the caching and paging mechanisms that he used, including an interesting trick to cache the Ajax responses (essentially query results) as XML files on the file system to speed up repetitive queries. Using a Ruby sweeper method to invalidate the cache when model objects changed made for an elegant implementation.

My main interest was to learn more about Adobe Flex and it was useful to get hear some real world experiences; it was a well spent evening.
