Developing Rich Internet Applications (RIA’s) by combining Flex with Turbogears.

Fred Sells did this presentation for the OrlandoJUG. Here's the writeup and I'll attach the source code to this discussion so we can work through it. Stay tuned for the code!

"Flex is a (mostly) open source IDE from Adobe that uses seamlessly combines XML layout definitions with ActionScript programming to create Flash applications. A fairly robust application can be built using the xml layout definitions with minimal ActionScript programming. Flex applications support a wide variety of server-side API’s, including XML and JSON.

Turbogears is an open source web framework written in Python that is similar to Ruby on Rails. Turbogears supports all the major RDBMS’s and uses either SqlAlchemy or SqlObject to provide Object-Relationship-Mapping (ORM) to simplify server side coding. A basic web application can be implemented in just two files: a database model and a controller containing the business logic. Although Turbogears is primarily used with any one of several HTML templating engines, it also supports JSON."

This presentation will focus on rapid development of RIA’s using Flex on the client side with static XML files to simulate server-side responses, then migrate to JSON with a Turbogears backend."

Podcast: Safely Changing Software to Avoid Incidents: A Conversation with Justin Sheehy

In this podcast, Michael Stiefel spoke with Justin Sheehy about how to safely put software into production without creating production incidents. Among the topics discussed were the futility of root cause analysis, and the importance of having a shared language for discussing incidents. This discussion included the need for software to be malleable as well as observable.
