RobotLegs is an IoC framework that’s been rising on the Flex framework scene. It’s a pure AS3 microarchitecture so it can be used in non-Flex projects as well. One thing that I like about the framework is that it does a pretty good job of telling you what’s wrong when you’re building your app. For example it’ll let you know if you’ve missed adding a class to the context. In this presentation I’ll show you how to set up a Flex app from the ground up using RobotLegs. In addition I’ll show you how to set up Flex Unit with RobotLets so that you can write unit tests or do test driven development for your project. I’ve worked with several Flex frameworks and RobotLegs is one of my favorites so far. This will be more of a live coding session than a theoretical talk about IoC. In this session you’ll learn how to set up your package structure, create a context, create a central data model, map events to commands, create and communicate with services, set up your views and use mediators as backing classes that will contain the ActionScript for them. I’ll also share a technique that I’ve been using that splits the context up so there isn’t one giant class to manage.

San Diego Flash Users Group: Flex Best Practices Presentation

To start 2009 off I gave my first presentation to an awesome group of Flash and Flex developers in San Diego. The presentation was created from the two articles I wrote in 2008 for the Adobe Developer Connection on Best Practices for Flex development. I’ve kept the Powerpoint presentation offline until now. Some of the content is a little dated but it’s probably still worth checking out. I may update this presentation with everything I’ve learned over the last year and for the upcoming changes coming in Flex 4, if time permits.

Java Programming II at UCSD

After wanting to learn more about Java for many years I decided to go back to school and take a structured class. This was the first time I’d set foot in a classroom since about 1998. It was through the UCSD Extension program but classes were held on the UCSD campus. It was pretty cool to walk around the campus and see the “college” life again after so long. In addition this was the first time I’d ever taken a class at a University, my previous college experience was at a community college. The instructor Kent Yang was really awesome and the class was killer! I learned a lot more about Java, OOP, Unit Testing and Design Patterns. This knowledge was all transferable into AS3/Flex so the experience was well worth the time and investment.

Check out the class details here.

The Flex Show Episode 71: OOP w/ Sean Moore

The Flex Show is awesome, simply stated. Jeffry Houser has done an excellent job with the podcast and I’ve been a fan for a few years now. One of my goals was to be a guest on The Flex Show and in 2009 in became a reality. I was able to put together a talk about OOP in regards to Flex and ActionScript development. The Java class helped solidify my knowledge of OOP so hopefully the talk will help others grasp some of the fundamental OO concepts. It was an honor to be on the show and I really appreciate the opportunity. Hopefully I can do another show sometime in the future. Maybe on the Mindset BCI work I’ve been doing lately.

You can listen to my talk on The Flex Show here.

Orange County Flex Users Group: Flex Best Practices Presentation

Laura Arguello was kind enough to invite me to give my Flex Best Practices preso at the OCFlex Users Group in March. This gave me a chance to visit the ASFusion office before the preso and hang out with Jeremy Saenz (aka The Flex Gangster) a bit as well. The crowd at OCFlex was really great and very patient as I got set up and had some trouble finding a room at the venue big enough for everyone. Thanks again to ASFusion and the OCFlex Users Group for inviting me to present. It was a great experience!

Technical Authoring for O’Reilly InsideRIA

2008 was a big year for me and authoring. I wrote articles for Adobe, Flash Magazine and O’Reilly’s InsideRIA. I continued the trend in 2009 by writing three featured articles for InsideRIA. Rich Tretola is one of the coolest guys I know and such a pleasure to work with. He helped me a ton with the articles I wrote this year through the good and the bad. Another person I really have to thank is Matt Chotin. His feedback on my Flex 4 article was a huge help and I really appreciate his time and input! You can check out the articles I wrote for InsideRIA below:

Round up of ActionScript 3.0 and Flex optimization techniques and practices

Overview of Flex 4 (Gumbo)

Decorator Design Pattern

Technical Reviews for Manning Publications

Reviewing books is great for a lot of reasons, it helps your writing skills, you get a preview of the books before they’re published and you get to contribute to the quality of the books being published. I do the reviews on a volunteer basis and really enjoy and appreciate the opportunity to do so. In 2009 I had the privilege of reviewing three books for Manning. They are all great titles and I encourage you to check them out.

Hello! Flex 4

Flex On Java

Flex 4 In Action

Present.ly AIR Client Development

This is one of the larger apps that I worked on completely by myself. Dave at Intridea got in touch with a request to help them refactor an existing AIR application to best practices. This project was one of the best projects I’ve ever had the pleasure of working on. The app was cool, the concept was cool and the client was cool. The Present.ly service is a private Twitter like service for businesses, if you haven’t already taken a minute to check it out I encourage you to do so. Another really awesome aspect of this project is that the codebase for the AIR app is totally open source and available for download on GIT Hub. I was able to use Cairngorm and Flex Unit on this project which I feel really helped the codebase and application’s stability and scalability. You can check out the codebase and the finished app by following the links below:

Game Consulting and Development

A game development company contacted me for some assistence with consulting and development for a Flex and Flash based game. This was my first experience doing any game dev and it was really great. This was another awesome client. They are not public yet so there aren’t any links to share. I did want to note that game development is something that I’d like to do more of and hopefully 2010 will present more opportunities to do so.

Parsley

Learning Parsley was been on my radar for quite some time. I’ve been able to work with the framework quite a bit over the last few months and really like it so far. It’s quite a bit different than Cairngorm development but it offers more flexibility and is the preferred direction by many developers. IoC frameworks are all the rage and I am glad to be learning how to use them.

Presentation Model

This design pattern is great. It enables better unit testing for your applications and helps to decouple logic from views. Using the Presentation Model wasn’t totally clear at first but after working with it for a while I’m really beginning to like it. Having a bunch of code in MXML files wasn’t really ever all that appealing to me and using the Presentation Model really helps to separate this code out into pure AS3 classes.

ThinkGear Brain Computer Interface API

In an effort to end 2009 with a bang I released my ThinkGear API. This API enables the Neurosky Mindset Brain Computer Interface to communicate with AS3 based applications. So far I’ve been able to build a rough dashboard that uses my brainwaves as its data source. In addition I was able to tie my brainwaves into some AS3 based particle visualizations. You can see my demo video and learn more here. Control ActionScript with your mind!!!

Well here’s looking to 2010. I can’t believe it’s already been a decade since Y2K. It’s been a great decade for the Flash Platform we’ve all come a long way.

After reviewing the example that Chris provided I wanted to take things s step further and integrate Hibernate and MySQL into the project. I wrestled with the JAR’s, the classpath, the Spring and Hibernate XML markup, and the Hibernate Annotations for a while and then realized that I needed to get a firm understanding of some Spring fundamentals. Manning’s Spring in Action was recommended by a colleague and so far has been really shedding some light.

I was able to create a simple Spring project (no Flex, no BlazeDS, no Hibernate… yet) to help me understand some of the core Spring concepts. The IoC Container and AOP are two very important pieces of the Spring framework. This very simple project only utilizes the IoC Container. Aspect Oriented Programming is very cool and I also recommend checking it out. AOP is not covered in this example. (Check out cross cutting concerns.)

There is a simple Ant task to compile, jar and run the application. You’ll also need the latest version of the JDK for this application.

You can download the project using a Subversion client using the following URL:

http://seantheflexguy.com/applicationcontextex/

You can also download a zipped version of the project here:

http://seantheflexguy.com/java/ApplicationContextExample.zip

To run the project navigate to the directory where you downloaded the project, and extracted if you grabbed the zip. Then from the project root using a Terminal or Command Prompt issue the command: ant to compile and: ant run to run the application.

The first version of the application used a BeanFactory. This second version uses the ApplicationContext class instead. BeanFactory is in Spring’s core module, it’s the main Spring container that provides DI. The ApplicationContext module builds on BeanFactory providing additional capabilities such as: internationalization and validation support and access to the application event lifecycle.

The Simple Spring Example Project should help you understand the most basic level Spring mechanics. The only JARs required by the project are spring.jar and the commons-logging-1.1.1.jar, both are included with the project. The Ant build file will set the CLASSPATH for these JARs, if you bypass Ant make sure to set these on the CLASSPATH prior to compiling the application.

So far Spring really looks like a powerful way to organize and manage Java application development. You should take a moment to check it out. Also be sure to check out the Spring BlazeDS Integration.
