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...

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)...

There are a great many sessions at JavaOne 2013 that feature JavaFX. But only one of them dared people to attend the session. That session would be No Guts, No Glory! A Deep Dive into the Internals of JavaFX [BOF5802], presented by Steve Northover, Kevin Rushforth, and Richard Bair (all of Oracle). At first, I was wondering if the challenge would mean I'd arrive at the session, only to find...

Visual Library is a library in NetBeans, which you can use in standalone Java apps, for doing beautiful, complex, animated layouts. JUNG is a library for exploring graphs of connected data. What if we put those two things together? That's what I did. The result is on GitHub.
Video demo and more info over on my timboudreau.com blog.

In Java, implementing via SQL is a well-developed practice for database computation. However, the structured data is not only stored in the database, but also in the text, Excel, and XML files. Considering this, how to compute appropriately regarding the structured data from non-database files? This article raises 3 solutions for your reference: implement via Java API, convert to database...

In the most recently completed Java.net poll, a large majority of developers stated that they have not yet done any development using JavaFX. Java.net polls are not scientific, of course, but it's unusual for the polls to produce such a decisive result.
Participation in the poll was high: 2120 votes were cast, and three comments were posted. The exact question and results were:
Have you done...

According to research, most complex report development work can be simplified by performing the data source computation in advance. For example, find out the clients who bought all products in the given list, and then present the details of these clients.
In developing such reports, it is the “computation” part and not the “presentation” part that brings about major difficulties. In which stage...

In Java development, the typical data computation problems are characterized with:
Long computation procedure requiring a great deal of debugging
Data may from database, or Excel/Txt
Data may from multiple databases, instead of just one.
Some computation goals are complex, such as relative position computation, and set-related computation
Just suppose a sales department needs to make statistics...

In report development, we may need to present the data from multiple databases in one report, such as data from MSSQL database for CRM and Oracle database for ERP. If the reporting tool like iReport only supports single data source, then we need to consolidate the multiple data sources into a single data source.
The Crystal, BIRT, and other so-called reporting tools for multiple data source can...

The data computation layer in between the data persistent layer and the application layer is responsible for computing the data from data persistence layer, and returning the result to the application layer. The data computation layer of Java aims to reduce the coupling between these two layers and shift the computational workload from them. The typical computation layer is characterized with...

Recently, I read Why Big Data Projects Fail by Stephen Brobst. I can’t agree more with his opinions which exposed the problem I’ve been worried about. In this article, I am going to further discuss this topic to remind the enterprises to beware of falling into such pitfall of failure.
Let’s have a look on a positive example. As a successful enterprise in leveraging big data, how does Google make...

In Java development, we may encounter the complex set operations. Java alone is not powerful enough to save programmers’ efforts in implementing the computation details, which is time-consuming and poor in code reuse. In view of this, programmers usually resort to dynamic calculation script for set operation.
SQL is surely the first kind of script that comes into most programmers’ mind. However,...

Acteur is a pattern for pipelining work - a little DI functional goodness for Java. I might have been speaking Swahili when I wrote about Acteur last month. So here's a simple explanation of the design pattern behind it, with a simple sample project.
