null is not an object

Way back in May of this year (I have been thinking about this post for a while now!) Andre and I were down at JavaOne to give a presentation and also had the chance to take part in the always interesting (at least two years in a row now) RedMonk CommunityOne session. It was good to take part in the cloud computing, twitter and open source discussions - one great take away was “don’t drink and tweet”. I digress.

Of most interest to me was the round table discussion about “what is an RIA?“. There were various opinions on this that I will not repeat here and let you read over on RedMonk.

What didn’t come through on the RedMonk review was what I thought, arrived at through the great discussion, was really the defining characteristic of Rich Internet Applications. In the end it was not about flashy graphics or animations. The one defining characteristic of an RIA is that there is no page refresh.

That’s it. That is all there is to RIA. If you have an application running over the network that does not have a page refresh then that is an RIA - be it using Flash, Ajax or a Java Applet. The discussion went back and forth until Jeremiah Stone from SAP finally talked some sense (afterwards we had a very interesting discussion and I really need to follow up with him) saying that good design is dependent on the context of the problem being solved. Now this is a really important idea since if you are used to working with a keyboard accessible green screen application, a visual mouse driven GUI will probably be far less usable. It is all context dependent. I may take longer to learn the green screen application but it will likely pay dividends in productivity down the road.

At any rate, long story short, the one common theme that people presented was that an RIA is defined by an application that has no page refresh, whether it is made for a user of a terminal or a new web 2.0 application.

I had my epiphany at the very end of the session and was pretty much lost on deaf ears of people who were about ready for a cold one (aside from Duane who was thoroughly liquored already ;)) . However, I felt somewhat vindicated when I was reading James’ post about the session when I noticed that there was a comment from David Mendels of Adobe, who was possibly responsible for defining the term while at Macromedia in the early 2000’s. Indeed David suggested that the original definition of an RIA was an application with no page refresh.

Based on that I think that the case of the meaning of RIA can be considered closed.

RIA == No page refresh

Despite it occurring on one of the nicest days of the year so far in Vancity, sixteen people came over to the Nitobi offices and hacked the day away. The beer arrived early so those of us who’s projects made a turn for the worse were getting sauced already by two or three - just after the pizza lunch.

When everything was said and done, Yohei came out on top with a Papervision3D version of the Nitobi office! It was pretty damn cool and you can play with it below.

Alexei also showed his NitobiBug tool that is a cross-browser Ajax debugging tool similar to FireBug.

Thanks to everyone for coming out despite the amazing weather (which you can see out the windows of the model of the office below) and the opening of the new Vancouver Apple store
We will be having the next one some time in the fall I think.
