Virtual Technology Summit

Every so often, the "Powers That Be" pull together leading voices in various fields and host a virtual technology summit, free of charge to attendees. Guess what? It's that time again!

There are four different tracks, and the "summit" is actually "summits" - there will be THREE of these events, hosted at different dates/times to make it easier for anyone to attend, regardless of where on the planet they may be located. Here are the key details:


  • Java
  • Systems
  • Database
  • Middleware


  • July 9, 2014 09:00-13:00 PST Americas
  • July 10, 2014 09:00-13:00 BST / 10:00-14:00 CET / 12:00-16:00 MSK/GST EMEA
  • July 16, 2014 IST-10:00 / SG-12:30 / AEST-14:30 APAC


For the Java track, key speakers will include Dr. Fabiane Nardon, Reza Rahman, and Angela Caicedo - all respected speakers who know their stuff and convey it brilliantly. Do NOT miss this event!

Virtual Developer Day: Java ME, SE, and EE

It's an exciting time in the Java Jungle! There are a lot of things going on "in Java" right now, and as a result, there are several free webinars scheduled to provide introductions to technologies and concepts you might want to know a bit more about. Just recently, I mentioned the upcoming Introducing Java EE 7 webcast, and now there's another one you'll probably be very interested to attend. The best part(s)? You can attend from your home or workplace and it's completely free! The worst part? You may struggle to decide which track to take - they're all that good.

For this four-hour Virtual Developer Day, here are the tracks and their topics:

Separate dates/times are offered for western and eastern hemispheres; please click this link to learn more and register.

Keep the Java flowing,

Looking Through the Telescope From the Big End: Four Small Java Developments that Pack a Punch!

There are a LOT of exciting developments in Java, almost on a daily basis. Most of them make a big splash, and for good reason! But sometimes, it's the little things...

There have been a lot of small developments in Java that are pretty exciting, too. I'll pick out four of my favorites - each at a different level and/or stage of development or detail - and explain why they're a big deal. Let's get started!

Home automation

I had the privilege of watching Vinicius and Yara Senger give a presentation at Jfokus (available below at on Java EE and home automation. The Sengers developed the jHome platform and run it on GlassFish, controlling Arduino-based appliances in their home, office, and boat. I won't give away all the spoilers, and it isn't Java end-to-end...but the Sengers are demonstrating a compelling, fully open source (hardware and software!) package for Java working in harmony with even the tiniest of devices.


FIRST, or "For Inspiration and Recognition of Science and Technology", was founded by world-renowned inventor Dean Kamen. In his words:

"Our mission is to inspire young people to be science and technology leaders, by engaging them in exciting mentor-based programs that build science, engineering and technology skills, that inspire innovation, and that foster well-rounded life capabilities including self-confidence, communication, and leadership."

FIRST's vehicle for doing this is robotics. Teams of various ages use available technology components and their brains to develop and program robots to compete in some pretty tricky challenges. This isn't Robot Wars (no Real Steel destructive matches here), but it's just as engaging - for the teams and spectators alike.

The 2012 FIRST International Championship was held in St. Louis, MO, USA, and teams representing several countries participated. I was able to attend for awhile - with an event like this, you just can't see it all! - and chanced upon a team in the pit area with a homemade sign saying "We use JAVA!". I was directed to the 15 year-old programmer who proudly informed me that they use NetBeans and Java to program their robot. We had a nice conversation, and I was left with the realization that Java's original "embedded" mission is still being realized in ways that we don't often think about.

Raspberry Pi

Simon Ritter recently posted about his work with the Raspberry Pi and JavaFX 2. I had seen others relate their victories getting OpenJDK onto the little Pi, a small-but-capable computer the size of a deck of cards...but Simon (and those who provided assists in whatever form) took the bar and threw it up onto the roof. It won't win any supercomputer awards (well, not alone anyway!), but the Raspberry Pi's small size and low price now make a host of formerly-unrealistic uses possible. Even before much optimization is done, JavaFX 2 is already running. If you've ever migrated existing software (of any kind) to a new platform, you know that that first "clean" run can be elusive. I can't wait to see how far we can take this...just as I can't wait for my pre-ordered Pi to hurry up and get here!

Harmonization of Java ME, SE

Henrik Stahl was on the Java Spotlight podcast recently (link below) presenting a clear vision for the harmonization of Java Micro Edition (ME) and Standard Edition (SE). The devil is in the details, of course, but here's the good news:

1) There is a plan
2) The plan makes sense
3) The plan is being worked...diligently!

Without getting into those details or the challenges surrounding them (API synchronization, Jigsaw, etc.), a modern, consistent set of APIs and a modular architecture should excite Java developers wherever they may fall along the spectrum.

The Bottom Line

It's an exciting time to work with Java at any level, and that includes in the crevices where small and/or embedded devices often lie hidden from view. If you haven't already been involved in "Java in the small", check it out. And if you have a favorite I've missed, drop me a line or comment below! If you like it, chances are the rest of us will, too.  :-)

All the best,
