Devoxx France 2015 Explores The Future of Technology

2500 developers attended 4th Devoxx France this year, an increase of over a thousand attendees from last year. The organizers announced a new member of the Devoxx family: Devoxx Morocco, a conference that will take place in Casablanca during the third week of November.

In this 20th year of Java, the theme of Devoxx France 2015 was about innovations in technology over the next 20 years. In his keynote, Java architect Brian Goetz described a development approach that keeps up with the technical needs of developers. Java 9 will deliver a modular platform tuned to hardware requirements. CEO Quentin Adam of Clever Cloud considers that engineering roles are entering an age of specialization. Dan Allen, an open source advocate, author, and world renowned speaker, discussed the responsibility of developers to preserve digital information for future generations. CCO Stephan Tual discussed Ehereum, an open source and decentralized platform allowing the creation of P2P businesses with new infrastructure, communication and privacy.

Rodolphe Gelin, research director of Aldebaran, explains that Romeo, a new line of humanoid robots will become a companion capable of understanding emotions and anticipate situations in the every day life. “Robots are an additional platform for development” he commented. Pierre Yves Oudeyer, research director at INRA, discussed cutting-edge artificial intelligence research, in which robots are programmed to be curious and learn by experimenting like children. They become aware of themselves and their environment. They can even develop their own language. The humanoid robot Poppy is an open source robot for laboratories and research centers to collaborate on the artificial intelligence project. Eric Filiol, the head of ESIEA research lab called on developers’ civic responsibility to educate politicians who are passing laws about internet, and privacy without understanding technology. He made the room laugh when he suggested that “after Devoxx4Kids, we really need a Devoxx4politicians.”

All the keynote speakers agreed that no one can predict the disruptive technologies in the next 20 years like no one could have predicted the internet and its ubiquity in our lives today. Again this year was Seed Networking, where developers, startups and venture capitalists discuss business opportunities. New this year was the Café Philo to discuss about the digital world and the future of society. Devoxx4kids took place last Saturday. 50 kids were learning Java using Scratch and Lego Mindstorms.

Creative and Fun Hunting at Devoxx

Get the full development story of the Hunt Game with those two interviews. The hunt was about tracking beacons at the Devoxx venue and throughout Antwerp for points. Peters and Seghers share details about the phone application design, user experience, and beacon placements.

Hear from Johan Vos and Peter Kuterna about the programming challenge between the front-end designed by Peter and the back-end Johan built with Java EE 7, Glassfish 4.1 and Java 8 APIs.

Game Goodness: Devoxx Hunt

Was I really walking the streets of Antwerp at midnight, staring at my phone, hoping to find a beacon? I was! Attendees of Devoxx Belgium got to play Devoxx Hunt, a game to find sensors throughout the venue and city of Antwerp. In this video, game creators Johan Vos and Peter Kuterna discuss the how they built the game. Learn more about Devoxx Hunt at

Playground, Hackergarten, and Nighthacking at Devoxx!

The Devoxx Java conference, the premier Java conference which is running from November 10 to 14, 2014 in Antwerp, Belgium, is so popular because it was designed by developers for developers. In this interview, Tori Wieldt and I talk about some of the highlights including the new Playground, the place for developers to experiment with code. Other items on the 'not to miss' list are the Hackergarten, Nighthacking and the OTN interviews. Join any of these activities located in the exhibit hall for as long as you want.

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!
