Databases

The data warehouse is essential to enterprise business intelligence, which accounts for a great part of the total enterprise cost. With the global data explosion in recent years, the business data volume grow significantly, posing a serious challenge for enterprise data warehouse to meet the diverse and complex business demands. More data, more data warehouse applications, more concurrent...

J2SE

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. An apt analogy to this point may 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...

JavaOne

I was very pleased to see the JFrog team take me up on my suggestion early this year that "Maybe the JFrog team will consider giving a presentation on how they put all this together at JavaOne this September". Unfortunately for me, the session (Building a Massively Scalable Cloud Service from the Ground Up) was already filled to capacity as I walked up to the door, so I was unable to attend....

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)...

Business

Looking back on a relatively long period of time always makes me nostalgic. I can’t help but turn into a wistful old man, preaching the value of the “good old times”. In Magnolia’s case, fortunately, this is slightly different - there are plenty of things that are still great, and on an even more positive note - they are constantly getting better! However, I’d still love give in to my penchant...

Blogging

To save 45% on JavaScript Application Designjust enter code bevacquajn at manning.com. This was taken from Nico's blog. A couple of weeks ago, my book on JavaScript Application Design and front-end processes (which I began writing a few months ago) finally went into the first review stage. Yesterday, an early access edition was made available by Manning, this version contains the first 3 chapters...

SBT in Action by Joshua Suereth and Matthew Farwell has been updated! Save 45% and just enter promo code 112113jn at manning.com. What else is new? Chapter 6, "Process & IO with sbt's libraries" has been added to the MEAP (Manning Early Access Program). Chapter 6 takes a look at how sbt allows you to run external processes easily, and how to combine them in a shell-like manner. You’ll also...

GUI

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...

NetBeans

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...

Programming

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...

IDE

If the results of the just-completed Java.net poll are at all representative of the broader Java/JVM community (our polls are not scientific, of course), the indication is that Java/JVM developers like staying pretty much up to date when it comes to their IDE. A total of 159 votes were cast in the poll, which ran for two weeks. The exact question and results were: How frequently do you...

Education

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...

J2EE

Note this blog is obsolete, see https://www.manorrock.com/blog/ for the current blog 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!

Note this blog is obsolete, see https://www.manorrock.com/blog/ for the current blog 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...
