Global Day of Coderetreat

From the coderetreat.org website:

Coderetreat is a day-long, intensive practice event, focusing on the fundamentals of software development and design. By providing developers the opportunity to take part in focused practice away from the pressures of 'getting things done', the coderetreat format has proven itself to be a highly effective means of skill improvement.

This year, the Global Day of Coderetreat is happening on December 8. It sounds cool and fun, and of course, Java Champions and Java developers around the world are involved. Here's a small sampling:

You can go to http://globalday.coderetreat.org/  to look up events near you. It's a great opportunity to practice your craft.

Here's a video from an event last year to get a flavor:

Get Started with JavaFX 2 and Scene Builder

Up on otn/java is a very useful article by Oracle Java/Middleware/Core Tech Engineer Mark Heckler, titled, “How to Get Started (FAST!) with JavaFX 2 and Scene Builder.”  Heckler, who has development experience in numerous environments, shows developers how to develop a JavaFX application using Scene Builder “in less time than it takes to drink a cup of coffee, while learning your way around in the process”.

He begins with a warning and a reassurance: “JavaFX is a new paradigm and can seem a bit imposing when you first take a look at it. But remember, JavaFX is easy and fun. Let's give it a try.”

Next, after showing readers how to download and install JDK/JavaFX and Scene Builder, he informs the reader that they will “create a simple JavaFX application, create and modify a window using Scene Builder, and successfully test it in under 15 minutes.”

Then readers download some NetBeans files:
EasyJavaFX.java contains the main application class. We won't do anything with this class for our example, as its primary purpose in life is to load the window definition code contained in the FXML file and then show the main stage/scene. You'll keep the JavaFX terms straight with ease if you relate them to the theater: a platform holds a stage, which contains scenes.

SampleController.java is our controller class that provides the ‘brains’ behind the graphical interface. If you open the SampleController, you'll see that it includes a property and a method tagged with @FXML. This tag enables the integration of the visual controls and elements you define using Scene Builder, which are stored in an FXML (FX Markup Language) file.

Sample.fxml is the definition file for our sample window. You can right-click and Edit the filename in the tree to view the underlying FXML -- and you may need to do that if you change filenames or properties by hand - or you can double-click on it to open it (visually) in Scene Builder.”

Then Scene Builder enters the picture and the task is soon done.

Devoxx!!

 Announcing Devoxx London! Taking place on  March 26th and 27th, 2013 right before Devoxx  France on March 28th and 29th, this will be the first  edition of Devoxx UK!. The call for papers begins  on December 1st for Devoxx in London and Paris.  Speakers will be able to present at the two  conferences in the same week. Oracle committed  to fully sponsor the three Devoxx conferences in  2013 with a platinum sponsorship. Over 5,000 developers are expected to attend those conferences.

Five dancing NAO robots welcomed attendees at the keynote. Stephan Janssen offers the JUGs to replicate Devoxx4Kids workshops using his content and web infrastructure.  He recommended organizing kid events because “the workshops were really fun and such rewarding experience.” Stephan also announced the redesign of Parleys with Html 5 and GlassFish. Friendlier to speakers, they will be able to post their slides online before their talks and then sync the talk's sound track with the slides.

Nandini Ramani, VP of product development explained in her keynote address the growing role of Java from enterprise application development to cloud computing to embedded machine-to-machines systems. “Java continues to drive the applications and devices that enrich our interactivity with the world around us” she said.

The Java platform has expanded its reach with the OS X and Linux ARM support on Java SE and Java embedded with two new releases, Java SE embedded and Java Embedded Suite 7.0 middleware platformComing up next year is JDK 8, which will include Project Lambda, Project Nashorn and more. As part of that release, JavaFX will offer 3D and third-party component integration. At Devoxx, the slick and interactive schedules were designed with JavaFX. The earliest version of the Java EE 7 SDK is available for download and has WebSocket support, improved JSON support and more. 

Stephen Chin arrived on stage with his bike, ending his European NightHacking tour. Check the hacking sessions online here

50 Billion Served: Java Embedded on Devices

It doesn't matter if it is 50 billion or 24 billion, just suffice it to stay that there will be MANY connected devices in the year 2020. With just 24 billion devices, they will outnumber humans six to one! So as a developer, you don't want to ignore this opportunity. What if you could use your Java skills and deploy an app to a fraction of these devices (don't be greedy, how about just, say, 118,000 of them)? Fareed Suliman, Java ME Product Manager had lots of good news for Java Developers in his presentation Modernizing the Explosion of Advanced Microcontrollers with Embedded Java at ARM TechCon in Santa Clara, CA last week. "A radical architecture shift is underway in this space, from proprietary to standards-based," he explained. 

He pointed out several advantages to using Embedded Java for devices:
  • Java is a proven and open standard.
  • Java provides connectivity, encryption, location, and web services APIs.
  • You don't have to focus on and keep reinventing the plumbing below the JVM.
  • Abstracting the software from the hardware allows you to repeat your app across many devices.
  • Abstracting the software from the hardware allows allows parallel development so you can get your app done more quickly.
  • You already know Java (or you can hire lots of Java talent).
  • Java is a full ecosystem, with Java Embedded plugins for IDEs like Eclipse and NetBeans.
  • Java ME allows for in-field software upgrades.
Suliman mentioned two ways developers can start using Java Embedded today: 

Java ME Embedded Suite 7.0

Oracle Java Embedded Suite is a new packaged solution from Oracle (including Java DB, GlassFish for Embedded Suite, Jersey Web Services Framework, and Oracle Java SE Embedded 7 platform), created to provide value added services for collecting, managing, and transmitting data to embedded devices such as gateways and concentrators.

Oracle Java ME Embedded 3.2

Oracle Java ME Embedded 3.2 is designed and optimized to meet the unique requirements of small embedded, low power devices such as micro-controllers and other resource-constrained hardware without screens or user interfaces. Think tiny. Really tiny.

And think big.
