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.

In the three years I’ve had my blog there haven’t been any off topic posts. They’ve all been related to development, most related to Flex or the Flash Platform and a few Java posts. There is a first time for everything and this marks the first non Flex/Flash/dev blog entry.

Some of you may have already checked out the live DJ shows I’ve been broadcasting over the last couple of weeks. They haven’t been on at a regular time and there isn’t really a set length or format to them yet. I’ve just posted the link to my livestream on twitter and thankfully received a lot of interest and support. It really means a lot to me personally to have this level of interest and I’d like to thank everyone who’s tuned in!

I wanted to spread the word a little further with this blog post to anyone who isn’t on twitter or doesn’t follow my updates. I’m still working out a regular time and day for a show but suspect I’ll be broadcasting as much as possible.

For now you can most likely catch me on Saturday afternoons and evenings. I do broadcast the show during the week as time permits. Some of the shows have been during the day and many devs seem to like the tunes for coding to. The service I’ve been using so far is called Livestream. It’s really awesome and is a Flash based application. You should take a minute to check it out if you haven’t before. My channel/show can be found here:

http://www.ustream.tv/channel/seantheflexguy-dj-show

I’ll continue to post twitter updates for random shows but check on Saturday if you are interested, have time and are around a computer. The show is a live video and audio feed. Right now  you can really just see the turntables and mixer and my hands but I’m looking into another camera that can show a little more of the action.

I’ve been asked a couple times about the DJ’ing so a quick word on that. I actually started DJ’ing when I was 16. I was a DJ for a Hip Hop group for a while and also DJ’d regularly around Denver (Snake Pit for example) and Seattle. I also produce music and many of my songs and older mixes can be found on my music site here:

Well that’s it for now. Be sure to check out the show. There are good tunes on the regular! I spin everything from underground hip hop to ragga jungle to reggae/dancehall/dub to jazz and punk sometimes.

Thanks again to all of the listeners for your interest and support!!!! I really, really appreciate it!!!!

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.

Download the Flex Best Practices Powerpoint Presentation here.

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

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.

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.

Sean wearing the Mindset

Read and process data from your brain in ActionScript 3.0 with this open source API that I’ve created. You’ll need the Mindset hardware to utilize the full power of the API but you can run the ThinkGear Connector in “demo” mode and it will send simulated brain data to your app.

I’ve been interested in Brain Computer Interfaces for a few years now and was pleasantly surprised to find that Neurosky is now selling an affordable headset that reads brainwave data. The development tools are available for download from the Neurosky website for free. They provide a small piece of AS3 that shows how to read data from the ThinkGear Connector through a socket using ActionScript 3.0. I’ve abstracted the raw socket code into an easy to use API with documentation. Events are generated as the connector captures brainwave data from the BCI headset. You can register to listen for these events and get notifications as the brainwave data is read in one second intervals.

I’m currently working on a dashboard that displays the data my brain is generating using this API. It’s still a little rough but you can see the beginning in the video below. I’m also working on another project that feeds the brainwave data to some particle based visualizations in Flex. I think combining the brainwave data with Flash/Flex based visualizations could produce some very interesting results!

I’m planning on making this API open source and encourage developers to get involved. I can’t think of anything more exciting than reading your brain with ActionScript 3.0, Flex, AIR, etc. I truly think BCIs are the future of computing and we’ve hardly even seen the full potential yet. I currently need more examples to add to the project so if you’re interested in contributing those or anything else to the project please get in touch.

The game market is a great area where a BCI can be utilized. There is currently a demo game included with the Mindset when you purchase one. It’s pretty cool and if you are as interested in BCIs I encourage  you to take a look.
