Parallel computing in hadoop with esProc instead of MapReduce
Don't ask what open source can do for you. Ask what you can contribute to open source. Adopt a zombie project and get it back to life!
In this post we will be looking at code for a system designed to integrate all of the devices used to provide surveillance and security to extensive physical premises such as malls, campuses, and industrial parks. The approach I am taking involves the actor paradigm and the Java programming language. The selection of actors for this type of application is based on a number of...
I just finished delivering a talk at Oredev 2013 on better concurrency in Java 8. With Lambda’s being the biggest new feature I naturally needed to address what they had to offer.
In memory computation in Hadoop will great enhance data processing speed and volume.
One of the most compelling features about an OOP language like Java is that it provides a way to reuse code to add functionality within the classes you create. Essentially, when writing code in Java, seldom are you required to begin from scratch because the Java library comes with a great many classes that make it easy for you to attain a minimum level of functionality with relative ease.
A key consideration for the library designer in the normal conduct of operations is maintaining the ability to make changes or improvements to the library at any time without requiring the consumers (client programmers) of that library to do the same. In Java, a library consists of a logical grouping of .class files packaged together to make a working program.
Operators in Java work much like they do in mathematics, producing a value from one or more operands. An operand is any quantity on which an operation can be performed and in Java these include primitives and objects.
Basic arithmetic operators in Java include addition (+), subtraction (-), multiplication (*), division (/) and the assignment operator (=), all of which constitute...
Just recently I was engaged to assist with an application that wasn’t behaving. The application, running in a 1.7.0_45 JVM, relied heavily on a 3rd party SAAS framework. That vendor provided my client with a list of 26 different JVM flags that should be set. When faced with this long list of flags I couldn’t resist asking why all the flags and why these flags. After all there are more than 700 product flags defined in the JVM and to be honest, I’ve only a vague idea of the effect may have on a runtime.

A method to avoid database extension
As we know, the stored procedure is designed to handle computations involving complex business logics.

What if Swing deprecated tomorrow? How much butt hurt would there be and would everyone would immediately begin porting their applications to the JavaFX?
In the twilight of 2013 does JavaFX really replace Swing or are there use cases that dictate supporting Swing?
Does it even matter when more and more younger developers are forsaking Java altogether in favor of the 'Hipster Browser Flavor of the Week Framework.js'?
When At-a-Glance" (AoG) displays associated with complex data visualization aren't enough and you need something more interactive a combination of the NetBeans Platform and JavaFX again comes to the rescue. This post is Part 2 in the ongoing mini-series discussing this pattern from the perspective of a NASA MMS Ground System software operationally deployed at the Goddard Space Flight Center.
How to build a JavaFX visualization of data that must loaded dynamically while mitigating the hit to user experience. This tutorial will show you how to visually acknowledge the user with some sort of animation to let him know... "Hey I'm still here don't worry!" The following pattern is how you can easily accomplish this either from a straight Swing interop or embedded from a NetBeans Platform application.
Combining JavaFX 2.x and the NetBeans Platform has proven complementary in making some very useful "At-a-Glance" displays associated with NASA Ground System daily data product generation. The combination has proved to be a very effective pattern to extend and this post along with some following posts will explore this. Explanation, Justification and some cool screenshots will be provided.
Tired of JavaFX Scene Builder being run in a separate process? Fed up with no real integration between your favorite IDE and JavaFX Scene Builder? There may be a solution heading towards you. Follow this small series of blog entries to join me on my journey towards an embedded JavaFX Scene Builder in NetBeans.
Finally, with the new developer preview builds of JavaFX Scene Builder 2.0 a new...
