More Flash, Flex and Ruby E-Zines
In search of ever more content to clog up my Kindle, I’ve come across the following two e-zines worth checking out. Both are free downloads in PDF format. The Rubyist feels a little bit like the Pragmatic Programmer e-zine, but focused entirely on the world of Ruby. It has the same kind of smorgasboard of [...]

The Adobe Flex in a Week Video Training series is like attending a week-long [...]
Creating a Mac Desktop Icon in AIR

Adobe’s AIR installer on the whole provides a good user experience, and it creates a nice icon on the desktop for Windows users. But it does not create a desktop icon for Mac users, who then [...]
Automating Unit Tests in Flex
My company’s development culture is very test-driven, enabled in large part by our use of Rails on the server side. But we also feature an Adobe AIR application as part of our customer offering.
