OpenGL vs. DirectX: A Comparison

Share this post!

Vote this!

The competition between OpenGL and DirectX is possibly as well known as the wars waged between AMD and Intel enthusiasts. This topic has sparked the fires of many flame wars throughout the years, and I don't anticipate that changing anytime soon. I won't preach why I prefer OpenGL over DirectX, but rather lay out the facts and let you make that decision. So let's dive in!
Perhaps the most obvious difference is that DirectX, as opposed to OpenGL, is more than just a graphics API. DirectX contains tools to deal with such components of a game as sound, music, input, networking, and multimedia. On the other hand, OpenGL is strictly a graphics API. So what aspect of OpenGL sets it apart from the DirectX graphics component?  more...

5 things you didn't know about everyday Java tools

Some Java™ tools defy categorization and are frequently collected under the rubric of "things that work." This installment of 5 things offers up a collection of tools you'll be glad to have, even if you end up storing them in your kitchen drawer.
The Java platform is full of "bits of string" — useful command-line tools and libraries that most Java developers will never even know about, let alone use.Many of them don't fit neatly into any of the programming categories I've covered so far in the 5 things series, but try them out anyway: some could still earn a place in your virtual kitchen drawer.

5 things you didn't know about enhancing Swing

Share this post!

Vote this!

Swing is an older toolkit, developed long before the advent of beautiful user interfaces, and it's missing some of the components you might need for building rich UIs. Fortunately, open source projects like Substance, SwingX, and the Java™ Look-and-Feel Graphics Repository make up the difference. Author Steven Haines shows you how to painlessly add tree tables, syntax highlighting, and more to your Swing UIs.
User interface design and development have changed a lot in recent years, and some would say the Java platform hasn't really kept up. Swing, released in 1997, is still the standard toolkit for building user interfaces into the JVM. On the upside, it's a familiar standard and easy to work with; on the downside, it's missing some features that have become common to rich UI design.  more...

Best practices for developing Eclipse plugins

This tutorial highlights best practices when marking information to resources using markers, and then introduces annotations and decorators that you use to highlight markers within the workbench. By extending extension points, you can reuse and adapt the built-in functions in Eclipse and perform advanced resource marking, such as moving a text marker when editing text. We discuss methods that take advantage of the plugin model, which allows for an efficient, high performance, and integrated look and feel plugin.

Introduction
When developing a plugin for an IDE Eclipse environment, you have several design considerations. These considerations ensure that you:

• Do not lock up the user interface thread.
• Decorate the UI without impacting performance.
• Process data in the background.  more...

Efficient JavaScript unit testing

JavaScript code that runs on one browser does not necessarily mean it will work on others. Without unit testing this code, organizations pay money for testing and re-testing web applications when deciding to upgrade or support new browsers. In this article, learn how efficient unit testing of your JavaScript can reduce testing costs and make it easier for you to support more browsers.

A broken JavaScript code example
One of the biggest challenges facing web applications is the support of web browsers with different versions. JavaScript code running on Safari does not necessarily work on Windows® Internet Explorer (IE), Firefox, or Google Chrome. This challenge is inherited from the lack of testing the JavaScript code living in the presentation tier from day one. Without unit testing this code, organizations may pay for repeated testing of web applications after upgrading or supporting new browsers. This article shows you how to reduce testing costs using efficient unit testing for JavaScript code.  more...

Separating the GUI and Logic with a StateManager

Share this post!

Vote this!

One of the biggest mistakes new programmers make, especially when beginning to work with GUIs, is to mix the business logic with the UI code. This is poor practice for a number of reasons. First, it makes it difficult to isolate the data to ensure it's integrity. There is a saying in this industry- if a piece of data is in two places at once, it is wrong at both places. Redundancy in this fashion makes it difficult to ensure data integrity. For example, if one class modifies a count variable, and a corresponding variable is contained in another class, that second variable may not be updated in the second location. By separating the business logic from the UI, this problem can easily be avoided.

A second reason not separating the business logic from the UI is that it makes it hard to move to another UI platform. For example, by separating the business logic, it is easily develop to use a Swing GUI, a console application, or an Android application without rewriting more portions of the framework than necessary.  more...

N-Tier Application Manageability

Share this post!

Vote this!

While it is a fact that N-Tier applications tend to provide almost limitless scalability, the desire to change or add new forms of functionality can present a challenge in more than one arena. Growth on a large scale can make capacity planning quite hard. When available resources have been exhausted by applications, then there must be some sort of provision made to borrow resources in order to support unexpected workloads. This is where manageability becomes key. 
Manageability entails the sharing of resources, simplicity, and centralized management. Organizations are forced by complexity to maintain competitive levels of service via a flexible architecture that allows for reactive scalability as a means of having a positive impact on both cost and service level.  more...
