Learning how to figure out why things are going wrong is one of the key aspects of developing software. We call it debugging. While dealing with REST services and clients, things can go wrong and it would help a great deal to know how to find out what is causing the problems.
In this article by Samisa Abeysinghe, we will look into the techniques such as message capturing and analyzing to get to know if things are going fine, and if not, what sort of problems are causing trouble.Read Debugging REST Web Services in full
In this two-part article by Michael Badger, we will get comfortable working with Scratch by covering some basic concepts. Each Scratch project contains sprites with costumes, scripts, blocks, and a stage with backgrounds. In the first part, we built a couple of sample scripts to demonstrate how we can control the sprites in a project. For example, we used motion to move the sprites and forever loops to keep the sprite moving.
In this part of the article, we will use broadcast messages to coordinate the actions of multiple sprites. We will conclude this article by sampling and remixing projects from Scratch's sample projects and from the Scratch web site.Read Getting Started with Scratch 1.4 (Part 2) in full
Rich Internet Applications (RIA) have garnered a lot of attention in recent times and rightly so. They offer a rich and responsive user interface and embed several Web 2.0 features that are required in today’s applications. Key features among them include rich media integration, responsiveness, real-time, offline capabilities and a desktop/web deployment model.
There are several tools/frameworks available today to develop RIAs. One of the leading frameworks that has garnered a lot of attention and developer interest over the last couple of years is the Flex Framework from Adobe Systems.
This article by Romin Irani introduces the RIA development framework Flex and its development IDE Flash Builder 4 (FB4) to the readers. The article covers the following:
- What is Flex Ecosystem
- Setting up the Development IDE, Flash Builder Beta 4
- Sample programs that take the reader through the mechanics of developing applications using Flash Builder 4.
