Internet of Things (IoT) Hackathon in Brazil

SouJava is running a Raspberry Pi and Java hackathon at Campus Party, the week-long technology gathering of geeks, developers, gamers, scientists, and students in Brazil. Sponsored by Oracle Technology Network, the hackathon is designed for enthusiasts who want to create IoT projects with Raspberry Pi and Java. The objectives are for attendees to learn, practice, and innovative while creating an IoT project

Java evangelist Angela Caicedo opened the hackathon with an overview of IoT and Java development. Over two days, participants will build teams, brainstorm, attend training, get a kit from the organizers and hack on their own project. Onsite experts will be available to help participants. They are veteran Java developers of web, enterprise and embedded development. Among them are GlobalCode founder Vinicius Senger, senior developer Rubens Saraiva, SouJava leader Bruno Souza, Java Champion Yara Senger, product manager Bruno Borges and senior mobile developer Ricardo Ogliari

Java 8 is Coming to EclipseCon

By Guest Blogger Ian Skerrett

We are very pleased to announce that we have added a Java 8 Day to EclipseCon 2014. Java 8 is scheduled to be released in March, close to the same time as EclipseCon, so we thought it would be great to have EclipseCon attendees participate in the launch of the new Java release.

In collaboration with Oracle, a new 1 day event has been added to the EclipseCon schedule. EclipseCon attendees will have the opportunity to learn about Java 8 from Oracle and Eclipse experts. There will be sessions about Lambda’s, JDT support for type annotations, the new Java 8 compact profile, JavaFX, api design with Java 8 and more. It will be a great way to accelerate your adoption of Java 8. Check out the complete schedule.

The Java 8 Day will take place on Tuesday, March 18 at the Hyatt Regency Hotel San Francisco Airport. We will be offering $200 day passes for developers that just want to attend the Java 8 content. Of course all EclipseCon attendees will also be able to attend.

Register today to take advantage of the early prices.

Java EE 8 Community Survey - Part 2!

By Guest BloggerDavid Delabassee 

The second part of the Java EE 8 Community Survey is now open!

During the last 5 weeks, we have been positively surprised by the community responses on the first part of the survey. We have received a lot of valuable feedback! That means we have *a lot of data* to process, a really nice problem to face! Thanks to all who participated in Part 1! If you haven't, there still time to answer Part 1.

Part 2 of the survey is focusing on topics such as Cloud, Security, Logging, Deployment, Testability, etc. We are again soliciting your feedback on those different topics.

In a few weeks from now, once the results of the 2 parts have been distilled and summarized, we will share those results with the community. The next step would then be to ask you to help us prioritize those features.

Thanks in advance for helping us to set the initial directions of Java EE 8 by participating in Part 2 of the Community Survey.

Java Rocks More Than Ever

In a series of blogs full of technical detail and cross-platform comparison, senior developer Geert Bevin from ZeroTurnaround gives 10 reasons why Java is a great technology. He built software for musical instruments using C++, with Juce Library and CPython, and realized that he missed a lot from the Java ecosystem.

He has written the first six blogs, which include Java Compiler, the core API, Open Source, the Java Memory Model, HighPerformance VM and Bytecode. In his first blog about Java Compiler, he gives examples and recommendations on how to use the JVM's just-in-time, the compiler code versus the architecture, runtime rather than static or dynamic linking. 

Upcoming topics include: 
Intelligent IDEs
Profiling Tools
Backwards Compatibility
Maturity With Innovation

Internet of Things Interview

Java Evangelist Jim Weaver, Senior Engineer Gerrit Grunwald and Community Manager Yolande Poirier discussed the Internet of Things(IoT), Java Embedded, and the new IoT community page on Java.net. The page gathers blogs, resources and many sample applications from Java developers who create embedded applications with Java. "If we prepare developers correctly to be able to program those devices and put structures in place that monitor and control those devices, then we can have a very productive world of development: one that is powered by Java, that has the underline security and needed APIs, and that leverages Java developer expertise" Jim explained. 

"I use one Raspberry Pi with Open Dophin and many sensors to synchronize data instead of multiple Raspberry Pi's" explained Gerrit Grunwald. "Over the last 10 years, the server side was prepared very well and now it is time for the embedded side to catch up and combine everything in one big Java world" he added

At the Java Demogrounds: What’s Happening with Java SE?

Over at the Java SE demo booth, Oracle’s Aurelio Garcia-Ribeyro, Senior Group Product Manager, briefly discussed JDK 7 and  JDK 8.

“People may not realize that we’ve recently added new functionality to JDK 7,” he said. “So with JDK 7 u40, we added Mission Control and Flight Recorder to the JDK, something we're very proud of. Flight recorder is a feature that works a little like the flight recorder on a plane; you leave it on and it doesn’t really impact your production. It simply runs, and if you encounter an issue, you can go back and discover what triggered it after the fact. It’s quite useful in debugging horrible problems that occur only in production that you cannot really catch when you’re developing because you need it to be going for 15 days with a slow memory leak, but you don’t want to have to reproduce that because it’s costly and you don’t know when it happens. With flight recorder you just leave it on, set a trigger, and when something goes bad, it helps you figure out what triggered that event.”

I asked him about Java SE 8, which is scheduled for release in March of 2014.

“If you want to play with it, go to https://jdk8.java.net/ and download the developer preview. We’d like you to first try your existing projects, which should work just fine. Then after that, you should start playing with the new features like lambda and JSR 310, the Date and Time API. Lambda is the biggest change to the developer programming model. We are very excited about this.”
