Recap of JavaOne Kids Day 2014

Do you remember JavaOne Kids Day 2014?

It was quite a blast with ~135 kids learning Python, Minecraft modding, Arduino, NAO, Greenfoot and lots of other technologies using hands-on workshops. Satisfying and rewarding are the two words that will summarize helping with the event last year!

Just to recap, here are some pictures from the last year’s event:

One of the most vocal feedback from the event was:

Based upon this very popular attendee request, and extremely positive feedback from everywhere else, JavaOne 2015 is taking that event to a much bigger scale. However this event will only be successful if you are share your passion and time to educate kids.

How can I help JavaOne4Kids 2015?

  • Are you a technology educator?
  • Are you a school teacher who would like to deliver a workshop at a professional conference?
  • Are you involved with CoderDojo or Devoxx4Kids instructor who would like to give a workshop in San Francisco?
  • Do you like to tinker with Tynker, Scratch, Blockly, Greenfoot or any other such technology?
  • Have you been giving workshops on LEGO, Arduino, RaspberryPi, Intel Galileo, or any other fancy boards?
  • Would you like to show a real practical use case of Internet of Things to kids using simple software and hardware?
  • How about some Java, JavaScript, Scala, HTML5, CSS, Python, Ruby?
  • Building simple mobile applications using Android or iOS?

JavaOne Call For Papers is open. There is a special track for developers and educators who are interested in delivering a two-hour hands-on workshop targeted at children 10 to 18 years old. Presenters will be responsible for preparing all the content and required hardware and software for 50 children—exclusive of laptops, which will be provided.

If you’ve submitted talks for the main conference, then this would be a great opportunity to bring your kids. They can either attend the workshop, or even deliver a workshop.

We love young presenters!

To submit a JavaOne4Kids Day talk, select “JavaOne4Kids Day” as the session type. Even though you are required to populate a primary track, this field will be ignored.

Java Magazine New Edition


Want to know how to optimize Java performance, whether your applications are in a cloud environment or on the JVM?  

In this new edition, Kirk Pepperdine examines parallelism using the fork/join framework to boost performance. Michael Heinrichs, in “The Quantum Physics of Java,” looks at modern chip design and its effect on Java programs. Chris Newland discusses the effects of small source code changes and Java HotSpot VM switches in Java just-in-time (JIT) compilation, and Josh Juneau explores incorporating performance tuning into the development lifecycle. Our JCP Executive Series features Anil Kumar, a performance architect at Intel. And, check out the big data panel from JavaOne 2014. 

Finally, our cover story showcases Netflix, which fulfills 2 billion content requests every day. The company can do so because most of the services running in its architecture are built on Java and the JVM.

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.
