Recently I have come upon a blog article which discussed why Swing has to be Deprecated. My understanding of the author's argument was that since Swing looks ugly compared to HTML5 and nobody uses Swing anymore that it should be deprecated in favor of JavaFX. The theory was that by deprecating Swing and forcing users to upgrade to JavaFX then all Java GUIs will be better with the...

In the previous post in this mini-series regarding the work I do on NASA Ground Systems, I showed some screenshots demonstrating data visualization. The basic tech stack involves combining the NetBeans Platform with custom JavaFX views. This pattern provides some very useful "At-a-Glance" (AoG) displays associated with daily data product generation.
AoG is typically appropriate, especially...

So you need to build a visualization of data that must loaded and interface dynamically. Good looks are important so you chose JavaFX but you are starting from an existing Swing based application. No problem right?
But what if you have a lot of data to load into your Scene? How do you maintain a positive User Experience?
Maybe you are using the NetBeans Platform because... well...

As I get closer to deploying our 4th Operational Release of the Duke's Choice award winning GEONS Ground System Software I'm combining the NetBeans Platform with custom JavaFX views. This pattern provides some very useful "At-a-Glance" displays associated with daily data product generation. I'm fortunate to have access to quite a bit of complex and timely data much of which is custom to the...

#How to run the dev test cases
All of the test cases can't be ran on the windows platform because the firefox can't support the ajax and JSF based on the windows platform very well. If you want to ran the tests, please check out all of the codes to the linux, ubuntu or mac platform.
1). Download the firefox and install it, On my platform, I...

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...

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. I wanted a meatier example than the ones where you write a query to find all the people that make more than you do so I decided to write the example around was on how to sum up all the application stopped time records...

Exciting information technologies emerge from new discoveries and re-emerge from past discoveries at a rapid rate. Despite the glamor and curiosity appeal engendered by cutting edge technologies when they debut, after the hype fades and we look at what actually is there in the cold light of reason we find ourselves turning to our pragmatic side and asking:
“Ok, but what advantages do we...

This post introduces a new Java actor based open source sub-project of the project "Learning Actors in Java". This work will develop a premises guardian system. A premises guardian system is a distributed application whose purpose is to support the physical protection of premises such as office buildings, campuses, apartment complexes, shopping malls, etc. Protecting information...

Remote systems cannot be ignored. They are the heart of actor programming. The ability of an actor application to smoothly scale out geographically is a tremendous advantage in meeting the challenges of growth. Today we will learn the basics of setting up for remote interaction between actors. If you wish to set up to try coding a set of remote actor systems and do not as yet have a...

Configuration of an actor system affects the way in which the Akka actor libraries and microkernel interact with actors. The visibility of a configuration is limited to the specific actor system with which the configuration has been associated. The effective configuration for any given actor system is a merger of three sources. In Fig. 1 below the precedence of...

This week I am presenting a coding of a simple two actor application designed to show actor creation, message passing, and actor termination. This application is called the "Fortune Cookie Application". It is the next state of the art beyond the HelloWorld program. Despite its simplicity this application shows the elements that every actor application uses.
What We Will Be...

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 the binary...

Much of what you do in Java is to define classes that package data and functionality together by concept to represent the desired problem-space element. When you instantiate a class, you create an object that has it's own piece of memory made up of other objects. Java has a peculiar means of manipulating these elements in memory. This is to say even though you treat everything as an object, you...

This is the Voice of Ground Control! NASA Ground Systems and Java Technology
I am Sean Phillips and have been a software engineer for a while now. For the last few years I've been lucky enough to be a lead developer for some NASA Ground System software that has been deployed directly into the Mission Operations Control room. (Hence the righteous reference in the title of this blog)...
