Efficient architectures for creating MapReduce Pipelines 
by Fabiane Nardon, Java Champion and Big Data Expert

Crunching, aggregating, analyzing, transforming: real world data science applications usually perform several processing steps, each step adding more value to your data. Architecting and coordinating these processing pipelines in an efficient way requires a good understanding of the underlying mechanisms of MapReduce algorithms and a few tricks you only learn after you processed several terabytes. This presentation will show how to architect efficient MapReduce pipelines, how to integrate your pipelines with external datasources, like Redis, MongoDB or even relational databases, how to decide the best granularity for a job and when investing in a MapReduce architecture really pays off.

JavaScript/HTML5 Rich Clients Using Java EE 7
by Reza Rahman, Java Evangelist and Java EE Expert

The sea change in HTML5 is likely to shift the pendulum away from today's thin-client based server-side web frameworks like Struts 2 and JSF to JavaScript powered next generation rich clients. With strong support for REST, WebSocket and JSON, Java EE is well positioned to adapt to this change. In this heavily code driven session, we will show you how you can utilize today's most popular JavaScript rich client technologies like AngularJS, Backbone, Knockout and Ember to utilize the core strengths of Java EE using JAX-RS, JSR 356/WebSocket, JSON-P, CDI and Bean Validation. We will also introduce Oracle's own JavaScript rich client solution code named project Avatar.

How to Become an Embedded Developer
by Angelia Caicedo, Java Evangelist and Java Embedded Expert

Jump into the Internet of Things using embedded Java. This session walks you through the steps required to start creating embedded Java applications by showing real examples of how to use GPIO and the I2C devices. See how easy it is to program embedded devices and have some fun!

The focus of OTN's Virtual Technology Summit is technology and code--there are no product pitches. Don’t miss out on this great opportunity to learn from some of the best minds in the Java community.

So Much Happening at Devoxx

Devoxx, the premier Java conference in Europe, has been sold out for a while. The organizers (thanks Stephan and crew!) cap the attendance to make sure all attendees have a great experience, and that speaks volumes about their priorities. The speakers, hackathons, labs, and networking are all first class. The Oracle Technology Network will be there, and if you were smart/lucky enough to get a ticket, come find us and join the fun:

IoT Hack Fest

Build fun and creative Internet of Things (IoT) applications with Java Embedded, Raspberry Pi and Leap Motion on the University Days (Monday and Tuesday). Learn from top experts Yara & Vinicius Senger and Geert Bevin at two Raspberry Pi & Leap Motion hands-on labs and hacking sessions. Bring your computer. Training and equipment will be provided. Devoxx will also host an Internet of Things shop in the exhibition floor where attendees can purchase Arduino, Raspberry PI and Robot starter kits. Bring your IoT wish list!

Video Interviews

Yolande Poirier and I will be interviewing members of the Java Community in the back of the Expo hall on Wednesday and Thursday. Videos are posted on Parleys and YouTube/Java. We have a few slots left, so contact me (you can DM @Java) if you want to share your insights or cool new tip or trick with the rest of the developer community. (No commercials, no fluff. Keep it techie and keep it real.) 

Oracle Keynote

Wednesday morning Mark Reinhold, Chief Java Platform Architect, and Brian Goetz, Java Language Architect will provide an update on Java 8 and beyond.

Oracle Booth

Drop by the Oracle booth to see old and new friends.  We'll have Java in Action demos and the experts to explain them and answer your questions. We are raffling off Raspberry Pi's each day, so be sure to get your badged scanned. We'll have beer in the booth each evening. Look for @Java in her lab coat. 

See you at Devoxx!

New Java SE Version Numbering Scheme!

The releases with new functionalities and non-security fixes also called Limited Update Releases will be numbered in multiples of 20. The Critical Patch Updates (CPUs) will be calculated by adding multiples of five to the prior Limited Update and when needed adding one to keep the resulting number odd.

As an example: The next Limited Update for JDK 7 will be numbered 7u40, and the next 3 CPUs after that will be numbered 7u45, 7u51, and 7u55. The next release will be a Limited Update 7u60, followed by CPUs 7u65, 7u71, and 7u75.

This new version system will apply to JDK 5, JDK 6 and JDK 7 which are available on OTN Java SE Download page and

The change will: 
  • assign a fix/enhancement to a specific release in the bug systems. 
  • prevent the existing code from breaking. the versions will follow the format 7u44 and will not allow 7u44-2 for example.
  • leave “space” between planned releases for any potential unplanned ones.

Main Our Most Popular Tech Articles of 2011

You can stop holding your breath now. We have determined the Top 20 (meaning: most popular) Tech Articles Published by OTN in 2011!

What conclusions can we draw from this list? Well, for one: Traditionally, we publish a "Top 10" list at the end of the calendar year. But in 2011, there were so many popular articles published that this ceiling was too limiting.

Other conclusions:

  • Java developers love reading articles. Total domination of the page view numbers this year.
  • Adam Bien is not only a Java Champion, but a Page Views Champion as well. Neither Brittany Spears nor George Clooney would have been more helpful to us in that department.
  • You all seem fairly curious about Java 7, Java EE, and JavaFX.
  • If you have your own observations, let's see them in comments.

 Without further delay, here's the list:

  1. Fork and Join: Java Can Excel at Painless Parallel Programming Too! (Julien Ponge)
  2. Taking Your First Steps with Oracle Solaris 11 (Brian Leonard & Glynn Foster)
  3. Contexts and Dependency Injection in Java EE 6 (Adam Bien)
