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.

Crossed post from: https://blogs.oracle.com/poonam/entry/updates_to_the_java_troubleshooting
Mattis Castegren who is my manager at Oracle, and is the guest writer for this blog post would like to share some details on the Java Troubleshooting Guide. Here's what he has to say:--
With the release of JDK 8, the official Java Troubleshooting Guide got a big overhaul. All pages were looked over and updated for JDK 8, and the two previous guides for the JVM and for Desktop Technologies were merged into one.
In the last month, with the release of 8u40, we have launched the next phase in this project. In this phase, we have added a lot of chapters about the new supportability tools that have been introduced in Java over the last few years.
The biggest new additions are a set of pages on how to use the Java Flight Recorder (JFR). If you haven't used JFR before, you should definitely check out the following chapters:
These chapters contain step by step instructions on how to record a JFR and also goes through what to look for in a recording to find common issues. The chapters contain lots of screen shots and details on how to interpret the data.
Once you have learned the basics, you can also look at the following two chapters on how to use JFR to debug specific issues:
When you have read through these chapters, you will be ready to use this great tool to find bottle necks in your own application.
Other new additions to the troubleshooting guide is a new chapter on how to set up Java for better troubleshooting: Prepare Java for Troubleshooting, as well as a lot of minor updates and clarifications.
