The Developer's Conference Florianópolis, Brazil

by guest blogger Yara Senger

With over 2900 developers in person and another 2000 online, The Developer's Conference (TDC) in Florianópolis, Brazil, reminds us that Java is BIG in Brazil. The conference included 20 different tracks, and Java was the most popular track. Java was also a big part of the talks in the IoT, Cloud and BigData tracks. Here's my overview (in Brazilian Portguese):

Several JUGs were involved in TDC Florianópolis, serving as track leads, speakers and all-around heros, including

  • SouJava
  • SouJava Campinas
  • GUJava Santa Catarina
  • JUG Vale
  • JUG Maringá
  • Java Bahia
  • GOJava (Goinia)
  • JUG Rio do Sul
  • RS Jug (Rio Grande do Sul)

and I thank them for their support and commitment. It is a vibrant and fun community!

We saw that the IoT space is maturing rapidly. There are already some related to embedded in the region.  Java Evangelist Bruno Borges and Marco Antonio Maciel gave a view popular talk "Java: Tweet for Beer!" They demonstrated how to make a beer tap controlled by Java and connected to the Internet, using a visual application JavaFX with Java SE 8, running on a Rasperry Pi. Of course, they had to test the application quite throughly.  

We Brazilians are training the next generation of Java developers. TDC4Kids was as big success. We made a tour with the kids in all booths and almost everybody talked about Java. Java in government managment (Betha), Java on the 2048  (Oracle), Java on the popcorn machine and Java training (Globalcode & V.Office) and of course: Java & Minecraft!

OTN's Pablo Ciccarello was there to support the community.  He did several video interviews with JUG leaders and speakers (mine included). You can watch more videos on his TDC Florianópolis playlist

Thank you, Oracle and OTN for all your support. We interacted with thousands of Java developers at The Developer's Conference Florianópolis. If you want to join us, we are planning two more conferences this year:

Devoxx 2014 Vive La (Digital) Révolution!

Last week's Devoxx France conference in Paris was sold out months in advance. The conference is part of the Devoxx family and is organized by the Paris JUG for the francophone developer community.  

The conference provided an array of technical sessions, including conference sessions, hands-on labs, university sessions,  quickies, tools-in-action and birds-of-a-feather (BoF) that will become available on Parleys in coming weeks. The broad range of topics touched on Agile and DevOps methodologies, Web, HTML5, mobile, startups, cloud, Big Data, Groovy, Ceylon, Java SE and Java EE.  Senior engineer Paul Sandoz presented Java 8 lambdas in the stream, which is one of the main features of Java 8. The new feature is designed to enable bulk data. Professor José Paumard presented 50 new things that you could do with Java 8. He discussed ConcurrentHashMap, the new HashMap and Date & Time APi as well as small improvements that ease development. Not everyone will implement the lambdas right away, he said, but with Java 8 they will still be able to benefit from the new version. Java Evangelist Stephen Chin demonstrated the full power of Java 8 with lambdas running on Raspberry Pi, PandaBoard, the Lego Mindstorms EV3 and other embedded devices during his university session. 

The keynote speakers echoed this year's theme of "born to be" a developer in the digital era. They explained how developers have a strategic role and are makers of the digital revolution. For example, entrepreneur Kwam Yamgnane considers that, as craftsmen in the IT trade, the developer's job goes beyond coding to collaboration with other disciplines and understanding not just the direction of the product but also of their company and the industry. With this understanding, developers need to be creative and agile to build better products, explains senior engineer Geert Bevin. They can use the same principal to build their career and find their passion. 

The second topic of the keynote was about engineering becoming more mainstream.  With the advent of the digital revolution, everyone needs to learn about technology because of its impact on our daily lives, on our careers and on new business creation, explains INRIA researcher Serge Abiteboul. Enterpreneur Henri Fournet is training beginners in programming and business acumen at Simplon, a successful year old educational company serving low income neighborhoods. Directors Dominique Van Deth and Danny Gooris at Oracle discussed the shortage of engineers today. In order to fill out the gap, Oracle trains high school and university teachers in Java programming for free. 

In addition, there were several activities where developers could collaborate, code or just explore. At the hackergarten, developers and open source committers contributed to a dozen of open source projects.  At the future lab and hackathons, there were a number of homemade and fun projects. Attendees could learn and change the interface of JavaFX games. A robotic xylophone was controlled by Raspberry Pi and Arduino. Wafting dry-ice fog exposed the green beams of a musical light show. You could fly the Crazyflie Quadcopter and meet the development team. Stay tuned for the video made by the Devoxx France team with the Crazyflie strafing the crowd during the keynote and meet and greet reception. The Nao robot was programmed onsite to dance to M.J.'s Thriller and other music.  Home automation applications controlled temperature, water heater and lights.  At the Code-Story, experts coded applications in front of the audience. For the third year,  the Devops Mercenaries presented tools, expert accounts, and guidelines for engineering teams to implement the methodology. More focused on entrepreneurship was the 'afternoon of deciders' where developers and industry leaders met to discuss big data, as well as Seed Networking, a speed dating session between entrepreneurs and developers. Devoxx4Kids welcomed a dozen children to learn programming with the Nao robot and other programming tools like Scratch and Greenfoot. 

Join us next at Devoxx UK June 12 and 13 in London. This is going to be another amazing Devoxx experience!

Richmond JUG: Java and the Internet of Things

Join the Richmond, Virginia JUG for a special evening learning about Java and IoT. Sharada Achanta, VP of Product Management for Oracle Fusion Middleware, will discuss latest on development on Java for IoT. He'll cover what's new in Java 8 and Oracle Event Processing for Embedded Java, as well as example use cases where there is a convergence of IoT, Big Data/Fast Data and the Cloud.

Richmond JUG Meeting
University of Richmond
Jepson Hall, Richmond, VA
Wednesday, March 19, 2014
5:30 PM 

Come early to network and enjoy food. Announcements and a quick raffle of cool products from the Richmond JUG and meeting sponsors follow the presentation.

The demand for smart, connected products continues to grow, and this is a huge opportunity for Java developers. Estimates are there will be 20 to 50 billion connected devices by 2020, generating US$14.4 trillion in value. However, the IoT value chain is highly fragmented and complex, especially when it involves edge devices. Machine-to-machine development can be complex, and current options are closed and monolithic. We need new value business models and seamless device-to-data-center platforms to truly enable the "Internet of Things". Java enables an open, standards-based platform to deploy highly integrated, end-to-end, device-to-data-center solutions. If you are in the Richmond area, come learn how Java and IoT go together.

vJUG: Worldwide Virtual JUG Created

London Java Community leader and technical evangelist Simon Maple has created a Meetup called vJUG, with aim toward connecting Java Developers in the virtual world.

The aim for vJUG is:

  • Get technical leaders from around the world to present to the vJUG members (without travel cost concerns!).
  • Work with local JUGs to provide worldwide content to their members and help JUGs present to a worldwide audience.
  • Provide content to devs without access to a local JUG.
  • Be a hub that will stream content from other JUG sessions live. 

The vJUG is not intended to replace local JUG efforts. "The vJUG can never be, and will never be, as vibrant and valuable to its members as a proper local JUG can. Why? Because the true value in JUG meetings are the face to face interactions and personal networking," said Maple. "However, many people do not have access to a really active JUG with great speakers and awesome content. Or, like me, the closest JUG is about 90 mins away." WebEx and Google Hangouts are great, Maple explained, he hopes vJUG will provide more coordination of online events. 

Maple hopes that in the future, vJUG will provide

  • An Events calendar with reminders and links to up coming meetings.
  • A Newsletter with what's coming up and links to previous sessions.
  • Coordination of links to IRC channels which are active during presentations (to create a feeling of virtual community).
  • Comments and forums around sessions and presentations
  • A place where physical JUGs could advertise their sessions (i.e. a NY JUG event) to a worldwide audience, when streamed, via an event that people can sign up to.
  • A common Webex or Hangout.

Maple encourages both people who need a JUG and existing JUG members to join vJUG. "I'm looking forward to talking with many of you one to get members, speakers, and JUG support!" Join vJUG now!
