Hedge Fund Analytics in Flex

Bernhard Kappe, Monday, June 1, 2009 @ 9:37 am

We just published a case study on a Hedge Fund Analytics application developed in Flex. It's an extensible Flex based platform for real time analysis of hedge fund performance data, with dynamically updating charts, graphs and sophisticated filters for cumulative performance, return distribution, alpha, beta and correlations, commissions and fees, credit and sector exposure.

The system is designed as a modular platform which can consume data services from multiple sources, and can integrate multiple custom components. Custom components were designed to conform to a standard API. Components expose standard flex component properties and events so that properties and method references could be passed. This allowed individual dashboard applications to be built, fed data and customized at run time. Take a look at a video demo or read the longer case study on the Pathfinder site.

Learning PureMVC the Hard Way (is there any other way?)

Dietrich Kappe, Tuesday, December 23, 2008 @ 1:29 pm

This ends week one of my investigations into PureMVC. So far I'm impressed with the framework itself in it's many versions and incarnations, but the documentation and tutorials for platforms other than Flex leave something to be desired. To all those folks that claim that Cairngorm is easier to learn than PureMVC, I can agree, but only because of this lack of good documentation.

So what should we Java/GWT developers do? Taking a cue from my colleague Noel Rappin, we should Read the Source, Luke. This code reading is a triangulation excercise worthy of Bill Clinton, involving API docs, source in other languages and source in other versions and platforms.

Underwhelmed by JavaFX 1.0

Ivan Moscoso, Saturday, December 6, 2008 @ 5:52 pm

By any measure, I should be a perfect candidate developer for JavaFX in its 1.0 release. All the more painful, then to recognize its deficiencies so early on.

While I work with a wide number of languages and frameworks, my career has focused on Java for most of the past ten years.

I mention this because there are some who might say that 24 hours is not enough time to make educated judgments on JavaFX. Perhaps, but it has been my experience that a day is enough time to develop a sense of curiosity or excitement about a new technology or framework, even if you don't completely "get it" yet. This happened for me the first time I played with Spring, with Squeak, Groovy, Rails, GWT, iPhone development, Flex, jQuery, etc. The list goes on and on. Without a sense of curiosity or excitement, one finds it hard to invest much time working with those technologies. And when something fails to stimulate a certain level of curiosity or excitement off the bat, it leads me to conclude one of two things:

• I must not be the target audience.
• There is little or no value in its current form.

Only in this case, I feel pretty certain that I am the target audience for JavaFX. I must be, right? But sadly, I'm left to conclude that there's not much to see here. Here's a list of things which I didn't much care for:

Defining RIA Interaction Patterns on time in Flex Agile Development

Sasha Dzeletovic, Friday, October 17, 2008 @ 2:19 am

Putting more attention to User Interaction Design is naturally becoming a standard practice with RIA.

With RIA technologies, classic Interaction Patterns are only building blocks, not solutions. With raised possibilities, Patterns have become more complex.
