JavaLand is a community conference in Germany that is held in an amusement park. Come learn not only about Java and technology, but also about how geeks have fun!
We will have a live NightHacking stream running from the Java Community Area on Tuesday and Wednesday with an all-star interview line-up. Each day will also conclude with an exciting combined vJUG session, which you won’t want to miss!
Schedule (Time Zone is CET)
The seventh annual JVM Language Summit took place during three days earlier this week. "It is a small room gathering of JVM and language implementers" explains JVM Architect John Rose. The number of attendees is intentionally limited so they can discuss topics with presenters and each other. The talks and discussions were about " the use of the JVM to implement new languages, and language constructs. What the pain-points are and how to evolve the JVM to fix the pain-points." Watch John's interview and learn about Valhalla and Panama, two new Oracle projects related to the JVM.
The summit sessions will be available online for free in the coming weeks.
SouJava is running a Raspberry Pi and Java hackathon at Campus Party, the week-long technology gathering of geeks, developers, gamers, scientists, and students in Brazil. Sponsored by Oracle Technology Network, the hackathon is designed for enthusiasts who want to create IoT projects with Raspberry Pi and Java. The objectives are for attendees to learn, practice, and innovative while creating an IoT project
At the gamification session of the International Oracle User Group Community (IOUC), leaders discussed how to drive membership. Typically, they give away licenses, books and goodies to encourage attendance at monthly meetings. Others have used gamification to get their communities to brainstorm on mascot names, or post pictures and comments on social media. Hackathons also require the use of similar techniques to keep attendees motivated to create applications over several days. SouJava leader Bruno Souza successfully ran hackathons that combined brainstorming, team building, training, hacking sessions and prizes to keep participants engaged.
“Turn life into a game, drive engagement of audiences, make the experience more enjoyable and get users to come back ” are the key advantages of gamification according to user group leader Jim Bethancourt.
The forum platform Stack Overflow is a great example of running a thriving community of developers with its point systems. Contributors get rewarded with points for their useful entries and visitors easily find the most relevant and best-rated entries.
The ArabOUG has implemented a point system to keep its community active. The group gives out points to the members, who contribute applications, articles, and translations. It partnered with training organizations and other services to give its members free training and services in exchange for points. As a result, members don’t have to pay for services using online payments, which governments in many countries in North Africa and the Middle East don’t allow.
In an interview, ArabOUG leader Mohamed Chargui explains in more detail his experience using gamification.
Software Architect Daniel De Luca discusses Devoxx 4 Kids, a program to introduce children to software programming. "We want to teach children to be creative with computers and build games in an easy way instead of just using technology" explained Daniel De Luca. "The NAO robot is another computer with multiple sensors on their feet and hands, a sonar, and more." The events are currently planned in over 10 countries. The training resources are freely available on Devoxx4Kids. Daniel with other event organizers presented the Devoxx 4 Kids best practices session with tips and tricks to organize such events.
Today was the first day of the IoT Hack Fest at Devoxx, the Java developer conference in Belgium. The IoT Hack Fest started with the Raspberry Pi & Leap Motion hands-on lab. Vinicius Senger introduced the Java Embedded, Arduino and Raspberry Pi. Java Champion and ZeroTurnaround Geert Bevin presented the Leap Motion, a controller sensing your hands and fingers to play games by controlling the mouse for example. "Programmers are cooler than musicians because they can create an entire universe using all senses" explained Geert
Participants started building applications in teams using Raspberry Pi, sensors and relays. One team tested the performance of Tomcat, Java EE and Java Embedded Suite on the Raspberry Pi. Another used built an text animation using a LCD screen. Some teams are using the Leap Motion to close and open programs on the desktop and others are using it as a game control.
