New Java Champion Pratik Patel

Welcome New Java Champion Pratik Patel

Pratik Patel is a long time Java expert, advocate and community organizer. While working as a graduate student at the University of North Carolina’s SunSITE research lab (which was sponsored by Sun Microsystems), he learned about Java and was immediately hooked by the potential of the platform and the language. That year, in 1996, he co-authored the 2nd book on Java. The following year, he wrote the first book on enterprise Java. He went on to implement large-scale Java based systems in investment banking, health-care and telco in various places in the world including New York, London, and Hong Kong.

Starting in 2005, Pratik became involved with the Atlanta Java User’s Group (AJUG), and later became a board member. His work in bringing the world’s experts on Java technology to Atlanta have helped make DevNexus one of the largest community run Java centric conferences in the world. Around the same time, he started to share his deep knowledge of Java and the JVM to developers in the USA and around the world. He is a frequent speaker at the No Fluff Just Stuff tour and other Java-centric conferences. He also is the primary organizer of DevNexusJr, a venture that is part of AJUG to bring the joy of programming to the next generation of developers. Follow him at @prpatel

New Java Champion Henri Tremblay

Welcome the new Java Champion Henri Tremblay!

Henri Tremblay has been developing with Java since 1998. In 2003, he became a main contributor of  the EasyMock open source project and created the concept of class mocking. He also invented and coined the term "partial mocking". He is now the lead developer of EasyMock and Objenesis, both of which are projects used by numerous frameworks. Ojenesis is a technical project allowing class creation without calling the constructor. He has also contributed to many Java open source projects. He is currently helping on the JEP 260: Encapsulate Most Internal APIs.

Henri is also the founder of the PerfUG, a user group dedicated to performance. The group currently has more than 400 members. It recently received Java speakers including Kirk, Heinz, Richard Warburton and Jean-Philippe Bempel. He is now involved with the Montreal JUG. 

Henri is a frequent speaker at Java conferences. One of his JavaOne sessions was a hands-on lab with Java champions Heinz Kabutz, Kirk Pepperdine, Ben Evans and Martijn Verburg. Follow him @henri_tremblay

NightHacking Tour of Germany

Java Community Lead Stephen Chin and Freelancer Sebastian Daschner are touring Java User Groups in Germany. And, you can watch them live at NightHacking during JavaLand. 

In his presentation, Stephen will walk you through how to build your own retro handheld console that is powered by Java, runs on a Raspberry Pi, and is printed on a 3D printer. Some of the topics that he will cover along the journey include: hacking Java on the Raspberry Pi
, rigging input devices with Pi4J, Insane performance tuning on the JVM
, why your boss [or SO] needs to buy you a 3D printer!
 And of course your retro gaming mettle will be put to the test, so make sure to dust off your old 8 and 16 bit consoles to prepare. This presentation is about the most fun you can have while still legitimately calling this conference “work.” 

Sebastian will give an introduction of RESTful web services with Hypermedia as the engine of application state, what the benefits and costs of using this approach are and show different approaches how to realize such REST services with JavaEE 7 and JAX-RS. Most of the time will be spend demonstrating different implementations (plain JavaEE 7, existing libraries, etc.) with live coding. The session is held in English.

Java User Groups: Changing the World, One Line of Code at a Time!

What is the impact of user groups on their members, society and the extended Java community? In this article, Daniel deOliveira presents a detailed analysis of Java user groups, their governance and influence. Also known as Dr. JUG, Daniel is the founder of the Federal District Java Users Group (DFJUG) in Brazil, and is passionate about the benefits of Java user groups (JUGs).

Daniel shows the value of JUGs, which accrue not only from the core members of a JUG but also, perhaps surprisingly, from peripheral members and outsiders. In fact, he advises that "if you run into a problem and need solid information, important advice, or support, look for people in the core group, which is where the knowledge is clustered. But if you need fresh ideas or innovation, look for the people in the periphery."

He sees the power of JUGs as teaching machines and as forces for social good. "Teaching kids Java for free always receives the enthusiastic support of colleagues. Some groups "go the extra mile" by conducting educational activities in underprivileged communities or teaching Java to the deaf, the blind, and wheelchair users." Find out more insights about Java user groups in his article

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:
