Nice post here. A little ivory tower-ish, but interesting all the same.
Basically says, for the intents and purposes of those of us who actually do the coding, the Events system in Flex is the built-in Observer pattern.
We need to use more Observer-based custom components in Flex. Especially since Flex expects us to do so. I'm halfway through a pretty nice project right now, and I regret not taking the time to make my custom components. Instead, everything is now in 1 application MXML with custom components that are "1 level deep" if you get my meaning. I used to have the notion that, if code isn't sharable, then I can refactor that into a custom component later; let me just get it working first.
I think now that even if code isn't sharable, I still need to create a new custom component. I need to dare to go deeper than "1 deep". For my sanity's sake.

var s1: String = "gerard";
var s2: String = "gerard";
Alert.show( (s1 == s2).toString() );
In Actionscript the above displays true. Apparently there is a built in string comparison operator in Flash that compares the content, instead of the object references themselves.
This is actually intuitive. If I give anyone on the street 2 identical Bibles, and ask them "are they the same?", they would say "yes". Java devs will tell you their content is the same, but they are in fact 2 different instances of the books.
I wonder what else is Java programming doing to my brain...

Here are the steps I took to install the iOS SDK.
- Checked my OS X version: I had 10.5 (Leopard)
- Found my Snow Leopard DVD
- Upgraded Leopard to Snow Leopard. I should have done this a long time ago.
- From the same Snow Leopard DVD, I installed Xcode 3.2
- Run Xcode
- Realized that the Xcode in the DVD did not include the iOS SDK
- Made angry noises
- Downloaded the iOS SDK. The version 4.2 is about 3GB. It includes Xcode 3.2.5, and the OS X SDK as well.
- Installed Xcode, iOS SDK, OS X SDK et al
- Realized the iOS SDK will take up more than 8GB on my Macbook
- Made incredulous noises
- After installation, I ran Xcode, and created a new project. And yes, I was able to create an iOS application.
