GUI

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...

J2SE

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...

Education

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...

Introduction 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...

Introduction 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...

Programming

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...

Each of these objects can be described in terms of the classes or types to which they belong for instance a maple tree belongs to the class of tree or is a type of tree, a bicycle is a type of cycle, a car is a type of vehicle. OOP is thus a very powerful language abstraction that allows you to simplify the complexity of a problem while retaining its value. Java is an Object Oriented...

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...

JavaOne

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)...

J2EE

JavaEE 7 and Glassfish 4.0 were released a little while ago. What is in the future? Well, see the Aquarium blog for the latest Glassfish Roadmap. And that is it. Enjoy!

If you started reading because of the title I got you! Anyway all jokes aside the JCP process is quite unique. It has been serving the purpose of the Java community for quite a while. In the past people have complained that you could only file or influence JSRs if you were part of a big company. Well that has been a thing from the past. For a while now it is possible to join the JCP in different...

Tyrus 1.3 has been released, get more information here. Or download it from here. Glassfish users should take all the Tyrus JAR files and replace them in the modules directory with the downloaded ones to get Tyrus 1.3 working in Glassfish. And that is it. Enjoy!

See the release notes for what was fixed. If you want to download it, see this page for more information. Enjoy!

Databases

If you are having a problem with your JPA queries and you are trying to understand what SQL queries it actually sends below the covers you can configure the JPA runtime to show the actual SQL statements it sends over. How? Well for EclipseLink you would add the following to your persistence.xml file.   <property name="eclipselink.logging.level" value="FINEST"/>...

Business

a little discussion in a television series here that i am the speaker. the topic is Java. The host, TV Excelence, said any update for Java and why Java is silence now. I said there are Java worlds which use Java but we cannot said it is Java, but use Java. 1. BigData with Hadoop under Apache , is a new ecosystem that based on Java. 2. Smartphone/Gadget with Android under Google with Apache...

NetBeans

At JavaOne 2013, I had the privilege of speaking for 10-15 minutes with Sean Phillips, Senior Software Engineer at a.i. solutions. a.i. solutions was a JavaOne 2013 Duke's Choice Award winner, and Sean had come to the Java.net table in the JavaOne Exhibition Hall seeking me. This was fortuitous, because among all of this year's Duke's Choice Award winners, the one that's closest in its...
