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 Java.com

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)
  4. Unit Testing for Java EE (Adam Bien)
  5. Neural Networks on the NetBeans Platform (Zoran Sevarac)
  6. Oracle Senior VP Steve Harris on Oracle’s Vision of Java (Janice J. Heiss)
  7. Oracle Database 11g Express Edition Quick Tour (Przemyslaw Piotrowski)
  8. Looking Ahead to Java SE 7 and 8: A Discussion with Oracle’s Java Language Architect, Brian Goetz (Janice J. Heiss)
  9. Working with Java SE 7 Exception Changes (Manfred Riem)
  10. Client-Side Improvements in Java 6 and Java 7 (Josh Marinacci)
  11. How I Simplified Oracle Database Installation on Oracle Linux (Ginny Henningsen)
  12. The DBA’s Guide to Setting Up Oracle RAC One Node and Oracle Data Guard (Martin Bach)
  13. Integration Testing for Java EE (Adam Bien)
  14. Build a .NET Application on the Oracle Database with Microsoft Visual Studio 2010 (John Paul Cook)
  15. Templating with JSF 2.0 Facelets (Deepak Vohra)
  16. Using Adobe Flex and JavaFX with JavaServer Faces 2.0 (Re Lai)
  17. Series: Oracle Exadata Command Reference (Arup Nanda)
  18. Better Resource Management with Java SE 7: Beyond Syntactic Sugar (Julien Ponge)
  19. Using Transitions for Animation in Oracle's JavaFX 2.0 (James L. Weaver)
  20. Scaling a PHP MySQL Web Application, Part 1 (Eli White)

Want to see your name on this list for 2012? We're always looking for good writers. Looking forward to seeing your proposals!

JavaOne India and JavaOne Russia

JavaOne India was held in Hyderabad in early May. There were approximately 3,000 developers in attendance. Sonya Barry, Community Manager for Java.Net, and I were in the Oracle Technology Network booth.

We gave away software DVDs of Pre-Built VMs for Developers.  They were a huge hit, even though the software is free and easy to download. Bandwidth is at a premium in India (the convention center was charging $40 USD a day for wifi!), so downloading 7GB can be a real challenge.  We ended up giving away all 3000 of our DVDs in a matter of hours! Once we gave away all the DVDs, traffic to the booth was slow but steady. In general, the crowd was very enthusiastic.

I had many great individual discussions. One group of developers were wondering if it's better to take a technical track and then switch to Sales, or get trained in Sales/Business and move to a technical track. I explained that IMO, it's better get technical training first, and then decide where do go from there. I also had some nice discussions about Computer Science education in India, and let some people know about Oracle's Higher Education User Group (HEUG).

It was my first trip to India. I loved the people, the food, and the India Marketing Team (thank you!!). 

Sonya also went to JavaOne Russia, her blog about both trips is here.

(thanks for the great photo, Arun!)
