Hacking with Raspberry Pi and Java

Two new videos about Raspberry Pi GPIO with Java are now available. This hands-on training  is part of the IoT Developer Challenge and will help you to create a winning project to submit. This is a great opportunity to win a trip to JavaOne 2014! Submissions are accepted until May 30, 2014

In the first video, you will learn about the Raspberry Pi set up and the installation of Java SE Embedded and JavaFX. In the second video below, expert Vinicius Senger explains the Raspberry Pi GPIO and protocols as well as how to use the Pi4J project, a set of libraries enabling the access of the Raspberry Pi with Java. Vinicius also gives several demonstrations using a camera, LED lights, buttons and a relay board to connect to appliances. You can download the code of his demonstrations, including Pi4J Helloworld, PiPicture, Twitter4Pi and Lcdl2C

Compete in the IoT Developer Challenge!


Show the world your embedded Java + Internet of Things (IoT) application for a chance to win a trip to JavaOne 2014! 12 winners will receive a trip to JavaOne 2014, the #1 place to meet world-renowned Java experts. In addition, six students will receive laptops and certification vouchers. Team up and submit the video and code of your project  by May 30, 2014.

Don't know how to start? We are providing eight free online training sessions in March and April. They will introduce you to embedded Java Embedded, IoT, Raspberry Pi and more. Everyone who registers gets a chance to win a Raspberry Pi starter kit.  

Need just a little bit of help? We will provide experts along the way -- regular "office hours." Ask questions on the Challenge forums and check the online resources. There may be some source code and solutions you can use for your project.  

At previous developer challenges, we've had developers:

  • Connect a doorbell to a camera, taking a picture and sending it to a cell phone when someone rings the doorbell.
  • Help blind people figure out which recycling container to use ("put it in the blue can" doesn't help!)
  •  Control a toy monster truck from a phone (Monster Truck As A Service!) 
  •  Connect a heart monitor to Google glass so your doctor or trainer can see your heart rate.

This short video shows them in action: 

Entries will be judged based on their implementation, innovation and usefulness:

  • Quality: a well-implemented project that uses Oracle Java Embedded with computer boards, devices or IoT Technologies
  • Innovation: a new and innovative way of using Java Embedded.
  • Usefulness: a project that meets a business need.

Java EE Curriculum Survey


 Take this survey and help us better understand which APIs and Java versions are the most important to you as a Java  EE developer. The results of the survey will enable us to update our training material and certifications for Java EE 7 to better suit the Java community. 

The survey will take you ~5 minutes. Your answers will remain anonymous and you won't be contacted by Oracle as a result of answering this survey

Want to be in the Java Magazine?

Writing a Fix This code challenge is the easiest way to get published in Java Magazine. Give readers the chance to flex their brain muscles, have fun, and learn something new.

Java Magazine reaches more than 150,000 subscribers and is loaded with technical articles, community news, and success stories from an array of businesses. The magazine's success is the result of the expert writers who write about technologies that they have first hand experience with.

Pick a topic you are most familiar with and send as many code challenges as you want. The challenge can be about any Java technology, whether it is Java SE, Java EE, Java ME, or Java Embedded.

Submit a Fix This challenge today!  Just follow these simple steps:   

1. State the problem, including a short summary of the tool/technique, in about 75 words.

2. Send us the code snippet, with a short set-up so readers know what they are looking at (such as, "Consider the following piece of code to have database access within a Servlet.")

3. Provide four multiple-choice answers to the question, "What's the fix?"

4. Give us the answer, along with a brief explanation of why.

5. Tell us who you are (name, occupation, etc.)

6. Email the above to JAVAMAG_US at ORACLE.COM with "Fix This Submission" in the title.

Devoxx France Plays to a Full House!

Devoxx France started with the return of the Grrrail from Devoxx UK by le papa (the father) of Devoxx Stephan Janssen. As he announced to great acclaim during the keynote, the Devoxx 2013 sessions will be freely available on Parleys. He also received applause for his demo of the new Html5 version. 

The conference was sold out again this year with 1,480 attendees, which is 250 more than last year.  The conference was packed with Java related tracks touching on the web, architecture, Java technologies and infrastructure to name a few. The labs, quickies, conference sessions, tools in action catered to the ever-evolving needs of developers.

The sessions about Java EE 7, JavaFX and Java SE were all well-received with more attendees than available seating. The upcoming Java EE 7 generated a lot interest and especially for Websocket and standardized batch processing.  Oracle was a European partner; a premium sponsor for the 3 Devoxx conferences: London, Paris and Moscow.

The Devoxx France team did a fantastic job of managing the following parallel activities, in addition to the packed conference. They included a CTO track, a day on DevOps methodology, coding days and competitions. Developers coded for an afternoon to win the code competition. They also coded, created documentation, fixed bugs for open source projects in the Hackergarden.  Devops Mercenaries tackled multiple versions of native packages and the use of Kanban approach to prioritize in an all day event. CTOs and CEOs came to the decision maker afternoon to learn and share their cloud strategies in enterprise. 

6 to 14 year olds attended Programatoo, a programming workshop for a day during the conference. They learned to program with Lego windstorms. According to Nicolas Martignole, co-founder of Devoxx France, Programatoo was Devoxx's best investment for the future.As he announced to great acclaim during the keynote, the Devoxx 2013 sessions are freely available on Parleys. He also received applause for his demo of the new Html5 version.

Devoxx UK Highlights

The London Java community really put on a smashing first Java conference that was coloured with local flavour. The conference began on a keynote of patriotic fun as the national anthem was played as a picture of the Queen was displayed with the quote: "One likes to code". The participants stood politely, but did not sing.

The title of the keynote was "The Programmer" and was all about the act of programming, insights into who programmers are and tips to get better at it. Kevlin Henney received applause and cheers when he stated: "We didn't get into programming because we wanted to deliver business value. That's what we say during interviews." His knowledgeable presentation backed up with research was spot on and it's worth any developer's time to watch the replay on Parleys.

Oh, and do "mind the gap" between the train and platform as we are admonished nonstop by the station minders. As well, Mind the Geek, the clever tagline of the conference. But, if I don't mind the geek, what do I risk? Broken code, twisted error messages, suffering a memory leak or worse, I'm sure. Let us all mind our inner geeks, then?

With Devoxx UK, the number of Devoxxians will reach 5,500 across Europe this year. The hands-on labs, talks, quickies, birds-of-a-feather and bash run from 9:30am to 10:00pm in the spacious business design center with its mezzanine. 75 speakers talked in 50 sessions in 7 tracks about cloud, Java SE, methodologies, Java EE, web & big data, new languages on the JVM, and future Devoxx.

As if you didn't know, the French have already got a Holy Grail, and so refused to assist King Arthur and his Kiniggits in their quest. That was then, now the Brits borrowed the Grail from the French for the two-day conference and will return it for the beginning of Devoxx France starting tomorrow.
