"The Leap Motion controller is a tiny device that measures the position of your hands in 3D space and it gives you a bunch of information so you can do things with that data." explained ZeroTurnaround Senior Engineer Geert Bevin. He created an application that allows users to make music with their hands; another that maps a series of gestures for keyboard and mouse commands for games. He showcased how to use it to control a computer and a game.

In this video interview, senior architects Andres Almiray and Swen Reimers discussed hackagarten event taking place during the conferences. "A hackergarten is group of people coming together for a couple of hours. We decide the open source projects we want to code on. It can be fixing a bug, adding a new feature, creating a screencast, testing features and giving feedback to the project. The goal is to contribute to an open source project" explained Andres.
Devoxx Hackergarten focused on Java EE Lambda projects this year. Swen was the project lead and mentor for the Lambda projects. Some of them worked on JavaFX and Lambda event threads. "We discussed why things would not fit in an API, the lambda syntax, and what is available or not" Swen mentioned. They are running hackergarten around the world. The next ones will be at JFokus, JavaLand and the monthly events in Basel, Switzerland.

The robot is connected to touch and color sensors, has a gyroscope to orient and prevent it from falling, 2 motors for the wheels and another for arms, and an infrared sensor for the remote control.

Geert Bevin created an application controlling multi-colored led strip with hand gestures. The Leap Motion controller detects hand position in 3D-space and sends the X/Y/Z data straight to the led strip to control the intensity of the red/green/blue lights. The led strip was connected to a Raspberry PI with an Arduino bridge and could be piloted through REST calls running on an embedded Java server. In this video, Geert explains the project.

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.

Java Evangelist Stephen Chin is back on the road for a new NightHacking Tour. He is meeting with James Gosling at Kona, Hawaii, the launch base of the Wave Glider. The Glider is an aquatic robot which communicates real-time data from the surface of the ocean. It runs on an ARM chip using Java SE Embedded.

“People may not realize that we’ve recently added new functionality to JDK 7,” he said. “So with JDK 7 u40, we added Mission Control and Flight Recorder to the JDK, something we're very proud of. Flight recorder is a feature that works a little like the flight recorder on a plane; you leave it on and it doesn’t really impact your production. It simply runs, and if you encounter an issue, you can go back and discover what triggered it after the fact. It’s quite useful in debugging horrible problems that occur only in production that you cannot really catch when you’re developing because you need it to be going for 15 days with a slow memory leak, but you don’t want to have to reproduce that because it’s costly and you don’t know when it happens. With flight recorder you just leave it on, set a trigger, and when something goes bad, it helps you figure out what triggered that event.”
I asked him about Java SE 8, which is scheduled for release in March of 2014.
“If you want to play with it, go to https://jdk8.java.net/ and download the developer preview. We’d like you to first try your existing projects, which should work just fine. Then after that, you should start playing with the new features like lambda and JSR 310, the Date and Time API. Lambda is the biggest change to the developer programming model. We are very excited about this.”
