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:

Present.ly AIR source code at GIT Hub

Present.ly AIR Client

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.

Thanks to everyone who took the time to join the meeting. Thanks to Kyle and Chris for inviting me to present. Also thanks a lot to everyone who provided all the great feedback and questions. Dan made the journey down from the mountains to join us as well. Several attendees inquired about getting a copy of the slideshow. I think the articles that I wrote for Adobe are actually much better and cover even more material than the Powerpoint presentation. Here are the links to the articles:

Flex best practices – Part 1: Setting up your Flex project article

http://www.adobe.com/devnet/flex/articles/best_practices_pt1.html

Flex best practices – Part 2: Development practices

http://www.adobe.com/devnet/flex/articles/best_practices_pt2.html

If you would still like the Powerpoint preso email me and I’ll send it along.

There was an example application that I wanted to share as well. I’ll post it on this blog in the very near future. It utilizes many of the practices and standards covered in my presentation and the articles. I’d like to provide a little info or blog post at least along with the example…soon….

I’ll be giving this same presentation on Flex Best Practices in March at the OC Flex Users Group. Thanks to ASFusion for the invite!!

Thanks again to everyone who made it out last night. The audience was really great and had great questions and a great discussion. I appreciate everyone’s time and feedback. Thanks to Dolores for all of the help getting ready for the preso too!!

“The goal of this article is to help you gain a better understanding of the Strategy design pattern. The Strategy pattern is used to separate the areas of an application that differ from the areas of an application that remain the same. This design pattern sits on top of several fundamental OOP principals. For example the Strategy pattern uses the concept of programming to an interface rather than an implementation. Strategy also favors composition over inheritance. The reason you would use the Strategy pattern is to abstract an algorithm from a class and create a new class based on the algorithm. Using polymorphism the algorithms can be changed at runtime by the compositing class.”

Exploring the Strategy Design Pattern
November 3, 2008
http://www.insideria.com/2008/11/exploring-the-strategy-design.html

This was a great article to write and it solidified a lot of knowledge about OOP and Design Patterns. I may write another one on the Factory Method. Leave a comment if you have any interest.

In other news I’ll also have another Flex Best Practices article being published on the Adobe website soon.

I’ve also been researching Livecycle and BlazeDS a lot recently. I managed to get both set up and working on my laptop. There are a number of similarities however the default Livecycle setup runs JBoss and the default setup of Blaze runs Tomcat. So some system tweaks were needed here and there. In addition I also had an existing installation of Oracle that really hosed things up. The Oracle installer added some items to my laptops PATH variable which resulted in quite a bit of debugging. Next I installed MySQL. That was cool and I learned a lot. I’ve done the MySQL installation before however it’s been a while (4 years’ish). The next thing I did was locate a sample database from the web to play around with. I found a pretty large sample employees database on the web and installed it. Then I started trying to remember the various SQL statements needed to retrieve data, JOINs etc. While working on all of this I also found a way to expose my Blaze server to the open web, despite the dynamically assigned IP address from my ISP. That was really cool, but super slow. I was accessing the Blaze samples from my other computer across the web however it was too slow to deal with (not sure what the problem was there, more research is needed probably my upstream.) So the next steps are going to be to write some cool SQL statements to pull data from my sample database, then setup my Blaze application instance/context, write my Java classes (integrating my SQL), set up my remoting configurations and then finally I want to build a “dashboard” and pump the data into some Flex charts. I’m really busy with client work and articles right now so who knows when I’ll be able to finish but the whole experience was fun and I learned A TON.

I’ve also been working on a cool client Flex project and sneaking in time here and there for some music. Well gotta run for now, until next time… Happy Flexing!!

Mate: Event driven framework for Flex
by: Sean Moore, July 2008 for Flash Magazine
http://www.flashmagazine.com/Reviews/detail/mate_event_driven_framework_for_flex/

2007 was an AWESOME year for Flex and AIR. 2008 should continue this trend. Here are several different technologies and other items I plan on monitoring going into 2008. Some of these are bleeding edge, others are fundamentals which we’ve been studying for years.

“I’m sure that Flex skills will be one of the hottest skills to have in 2008.” – Yakov Fain

ActionScript 3.0
Essential ActionScript 3.0
Personally I plan on digging into the nitty-gritty details of the language. This includes refining knowledge of Errors, Events, Exceptions, Interfaces, Bitmap API, Display API and Namespaces to name a few. I’ll be reading Essential ActionScript 3.0 to do so.

Adobe AIR
http://labs.adobe.com/technologies/air/
The first full release of AIR should be coming in 2008. With the rapid growth and massive interest already I cannot even speculate what 08 will bring for this exciting, young technology.

Adobe Astro
http://labs.adobe.com/wiki/index.php/Astro
“The next major release of Flash Player, codename “Astro,” was first previewed at Adobe MAX 2007. The preview highlighted a few of the new capabilities the Flash Player team is working on for Astro: advanced text layout, simple 3D effects, and custom filters, blend modes and effects.”

Adobe BlazeDS
http://labs.adobe.com/technologies/blazeds/
http://livedocs.adobe.com/labs/blazeds/html/index.html
“BlazeDS is the server-based Java remoting and web messaging technology that enables developers to easily connect to back-end distributed data and push data in real-time to Adobe® Flexâ„¢ and Adobe AIRâ„¢ applications for more responsive rich Internet application (RIA) experiences.”

API’s
http://programmableweb.com/apis/directory/1?sort=date
I always keep an eye on this area of Programmable Web for new ideas for applications and mashups.

ASDoc
Using ASDoc
“ASDoc is a command-line tool that you can use to create API language reference documentation as HTML pages from the classes in your Flex application. The Adobe Flex team uses the ASDoc tool to generate the Adobe Flex 2 Language Reference.”

Brain-computer interface
http://en.wikipedia.org/wiki/Brain-computer_interfaces
http://www.techrivet.com/2007/07/23/NeuroSkyMovingBeyondConceptBCI.aspx
“brain-computer interface (BCI), sometimes called a direct neural interface or a brain-machine interface, is a direct communication pathway between a human or animal brain (or brain cell culture) and an external device.” The WII in Flash was cool, let’s see one of these plugged into the Flash Platform!!!

Cairngorm
http://labs.adobe.com/wiki/index.php/Cairngorm
http://www.cairngormdocs.org/
“The Cairngorm Microarchitecture is a lightweight yet prescriptive framework for rich Internet application (RIA) development.”

Cloud Computing
http://tnerd.com/2007/10/14/cloud-computing-the-next-big-thing-is-cloud/
Cloud_computing_wp_final_8Oct.pdf
“is a computing paradigm shift where computing is moved away from personal computers or an individual server to a “cloud” of computers. Users of the cloud only need to be concerned with the computing service being asked for, as the underlying details of how it’s achieved are hidden”

Design Patterns
http://www.javacamp.org/designPattern/
http://www.exciton.cs.rice.edu/JAvaResources/DesignPatterns/default.htm
ActionScript 3.0 Design Patterns: Object Oriented Programming Techniques
“In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations”

E4X
http://www.adobe.com/devnet/flex/articles/training_e4x.html
http://www.ecma-international.org/publications/standards/Ecma-357.htm
E4X: A new approach to XML processing
http://www.w3schools.com/e4x/default.asp
“E4X offers a natural, fluent set of language constructs for manipulating XML. In contrast to traditional XML-parsing APIs, XML with E4X performs like a native data type of the language. E4X streamlines the development of applications that manipulate XML by drastically reducing the amount of code needed.”

EcmaScript 4.0
http://www.ecmascript.org/
http://www.ecmascript.org/es4/spec/evolutionary-programming-tutorial.pdf
Microsoft trying to derail ECMAScript 4?
“ECMA-262 Edition 4 is the next-generation version of ECMAScript being developed currently by the ECMA TG1 working group.” This space is heating up, keep a watch on this one I have a feeling this is going to shape the future of the web in major ways.

Flash Media Server
http://www.adobe.com/products/flashmediaserver
“an enterprise-grade data and media server from Adobe Systems Inc. This server works together with the Flash Player runtime to create media driven, multiuser RIA’s.”

Flex 3 & Flex 4
http://labs.adobe.com/technologies/flex/
Keep an eye on Adobe Labs. Flex 3 will be coming out in 2008 and who knows we may even see at least some more talk about or get to provide additional input on the future of Flex.

Flex Custom Components
http://www.adobe.com/devnet/flex/articles/creating_components.html
Flex Component Kit Alpha for Flex 2.0.1
http://www.adobe.com/devnet/flash/articles/creating_as3_components.html
I think creating custom components for Flex is going to increase in demand in 2008.

Flex Performance and Memory Profiling
Performance and Memory Profiling
“Memory profiling lets you look at objects being created, take snapshots and compare them. Performance profiling allows snapshots for looking at cumulative and internal time.”

Flex Persistent Framework Caching
http://weblogs.macromedia.com/jd/archives/2007/08/player_update_p.cfm

Flex Refactoring
http://labs.adobe.com/technologies/flex/videos/refactoringdemo/

Flex Skinning
http://www.adobe.com/devnet/flex/articles/flex_skins.html
http://www.scalenine.com/resources.html
“If you want to redesign the appearance of the Flex components more radically, you can do so by creating a new set of skins for the Flex components that completely replace the built-in Halo Aeon theme.”

Hibernate
http://www.hibernate.org/
“Hibernate is a powerful, high performance object/relational persistence and query service. Hibernate lets you develop persistent classes following object-oriented idiom – including association, inheritance, polymorphism, composition, and collections.”

Hydra / Adobe Image Foundation
http://labs.adobe.com/wiki/index.php/AIF_Toolkit
“The Adobe Image Foundation (AIF) Toolkit preview release includes a high-performance graphics programming language that Adobe is developing for image processing, codenamed Hydra, and an application to create, compile and preview Hydra filters and effects.”

http://www.sun.com/training/catalog/courses/SL-275-SE6.xml
http://www.sun.com/training/catalog/courses/CX-310-065.xml
Here are a few links with training recommended for Java certification. Might be something to think about for the future.

JavaFX
http://www.sun.com/software/javafx/index.jsp
“The JavaFX product family delivers the ability to create interactive content, applications and services from the desktop to mobile devices to the living room.”

Microformats
http://microformats.org/
“Designed for humans first and machines second, microformats are a set of simple, open data formats built upon existing and widely adopted standards.” Microformats are being used in conjunction with Adobe AIR.

Occasionally Connected Apps
Monitoring network connectivity
One of the draws to using Adobe AIR is the ability to monitor network connectivity. This is one area I want to work with and research a bit more in 2008.

OOP
http://www.friendsofed.com/book.html?isbn=1590598458
http://www.adobe.com/devnet/actionscript/articles/oop_as3.html
“Object-oriented programming (OOP) is a programming paradigm that uses “objects” and their interactions to design applications and computer programs. It is based on several techniques, including encapsulation, modularity, polymorphism, and inheritance. It was not commonly used in mainstream software application development until the early 1990s. Many modern programming languages now support OOP.”

Papervision 2.0
http://blog.papervision3d.org/
http://papervision3d.googlecode.com/svn/trunk
http://blog.zupko.info/?p=76
“Features: Faster! ShadeMaterials, Shaders, ASCollada (animation support), Frustrum Culling, Multiple Viewports, Render to Scene and more. More features expected soon.”

Prisim
http://labs.mozilla.com/2007/10/prism/
“Unlike Adobe AIR and Microsoft Silverlight, we’re not building a proprietary platform to replace the web. We think the web is a powerful and open platform for this sort of innovation, so our goal is to identify and facilitate the development of enhancements that bring the advantages of desktop apps to the web platform.”

Refactoring
http://www.refactoring.com/
“Refactoring is a disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior. Its heart is a series of small behavior preserving transformations. Each transformation (called a ‘refactoring’) does little, but a sequence of transformations can produce a significant restructuring.”

Spring
http://www.springframework.org/
http://www.theserverside.com/tt/articles/article.tss?l=IntrotoSpring25
“The Spring Framework is probably best known for offering features required to effectively create complex business applications outside of the programming models that historically have been dominant in the industry. Next to that it is also credited for introducing previously unfamiliar functionalities into today’s mainstream development practices, even beyond the Java platform.”

SQLite
http://www.sqlite.org/
http://sqlitebrowser.sourceforge.net/
“SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.” This is used in google gears and Adobe AIR. Firefox also uses SQLite.

Struts
http://struts.apache.org/
“An open source framework for building Servlet/JSP based web applications based on the Model-View-Controller (MVC) design paradigm.”

Subversion
http://subversion.tigris.org/
http://svnbook.red-bean.com/
http://svnbook.red-bean.com/en/1.4/svn-book.pdf
“Subversion (SVN) is a version control system initiated in 2000 by CollabNet Inc. It allows users to keep track of changes made to any type of electronic data, typically source code, web pages or design documents.”

Surface Computing
http://www.microsoft.com/surface/
“Surface computing is the use of a specialized computer GUI in which traditional GUI elements are replaced by intuitive, everyday objects. Instead of a keyboard and mouse, the user interacts directly with a touch-sensitive screen, replicating the familiar hands-on experience of everyday object manipulation.”

Swing
Java Swing By Marc Loy
http://java.sun.com/docs/books/tutorial/uiswing/
“Swing is a widget toolkit for Java. It is part of Sun Microsystems’ Java Foundation Classes (JFC) — an API for providing a graphical user interface (GUI) for Java programs. Swing includes GUI widgets such as text boxes, buttons, split-panes, and tables.”

Thermo
http://labs.adobe.com/wiki/index.php/Thermo
“Thermo” is an upcoming Adobe product that makes it easy for designers to create rich Internet application UIs. Thermo allows designers to build on familiar workflows to visually create working applications that easily flow into production and development.

Technological singularity
http://en.wikipedia.org/wiki/Technological_singularity
“There is no clear definition, but usually the Singularity is meant as a future time when societal, scientific and economic change is so fast we cannot even imagine what will happen from our present perspective, and when humanity will become posthumanity.”

TouchLib
http://www.whitenoiseaudio.com/touchlib/
“Touchlib is our library for creating multi-touch interaction surfaces. It handles tracking blobs of infrared light for you and sends your programs multitouch events, such as ‘finger down’, ‘finger moved’, and ‘finger released’. It includes a configuration app and a few demos to get you started. It interaces with most major types of webcams and video capture devices”

UML
http://www.uml.org
http://en.wikipedia.org/wiki/Unified_Modeling_Language
“In the field of software engineering, the Unified Modeling Language (UML) is a standardized specification language for object modeling. UML is a general-purpose modeling language that includes a graphical notation used to create an abstract model of a system, referred to as a UML model.”

Unit Testing
http://code.google.com/p/as3flexunitlib/
http://www.adobe.com/devnet/flex/articles/unit_testing.html
“Unit testing is a procedure used to validate that individual units of source code are working properly. A unit is the smallest testable part of an application. In procedural programming a unit may be an individual program, function, procedure, etc., while in object-oriented programming, the smallest unit is a method; which may belong to a base/super class, abstract class or derived/child class.”

WebKit
http://webkit.org/
http://webkit.org/blog/
“WebKit is an open source web browser engine.” This is the browser used within Adobe AIR.

Here are a number of podcasts regarding software development. All of these topics are valid for Flex development. Enjoy!

Cairngen - Free
http://www.ericfeminella.com/blog/cairngen
This tool provides AS3 code generation for Cairngorm based Flex projects. You’ll need to have Ant installed and know how to run and modify Ant scripts so there is a barrier of entry here. It would be great if Cairngen had a GUI.

VASGen – Free
http://selfmummy.com/vasgen
There are a few issues with VASGen, like no package name support, but the AS3 code generation is pretty good. This tool is definitely worth checking out, especially considering the price. If you aren’t planning on using Cairngorm and you want a free tool this might be the solution.

UMLet – Free
http://www.umlet.com
This app can be set up as a Flex/Eclipse plug in. Pretty cool, no code generation from what I could tell though.

Enterprise Architect – $239-$135
http://www.sparxsystems.com.au/products/ea.html
At one point I had a trial copy of EA that was generating AS3, if memory serves me it did take a few hours of changing settings and research to get the code gen working though. Unfortunately the current price tag is out of my reach so no further information is available.

Visual Paradigm – $70-$59
http://www.visual-paradigm.com/product/vpuml/personaledition.jsp
Visual Paradigm claims AS3 generation but I’ve seen some concerns, and have my own (that doesn’t look like AS3 to me, notice the lack of a package?).
