3D Printing with a Java Rockstar

By Roger Smith


Controlling a 3D Printer with Java and VRL-Studio

I chatted with Java Rockstar Michael Hoffer on Tuesday at the Java Hub in the Exhibit hall about VRL-Studio, an innovative visual programming environment he created in Java that combines visual and text-based programming. Currently doing his PhD at the Department of Computer Science and Mathematics at the University of Frankfurt, Germany, Hoffer works at the Goethe-Center for Scientific Computing in Frankfurt. His research interests are in developing visual programming concepts in the field of modeling and simulation of highly complex physical processes including those modeled by medical scanning equipment.

Robots Look for Human Companions at JavaOne

By Roger Smith


Humaoid Robots Are Big in Japan

I spent part of this afternoon at the MakerZone, which is part of the Java Hub at this year's JavaOne Exhibit Hall, where I had a brief, enjoyable chat with Pepper, a 4-foot tall humanoid robot. Created by Aldebaran Robotics, Pepper is a social robot able to recognize and react to human emotions and carry on simple conversations in as many as 28 different languages. (I met and wrote about Nao, Pepper’s androgynous older sibling, in a recent JavaOne4kids workshop that showed how Nao could be taught to walk, talk, catch small objects and even dance). Besides being almost twice as tall as Nao, Pepper moves around on three omnidirectional wheels rather than feet like Nao. The Nao robot has been in development since 2006, while Pepper only has been around for a little over a year. Pepper’s added wheels give him greater range and almost 14 hours of battery life, which is three times the amount Nao has. The additional battery life was a requirement, said Nicholas Rigaud, Developer Community Leader for Aldebaran, since he was designed to greet and interact with customers in retail stores owned by Japanese mobile phone operator SoftBank Mobile, Aldebaran’s parent company.

New Java Releases Will Tackle Developer Pain Points

By Roger Smith


JavaOne 2015 Keynote Focuses on Future Java Platforms

The half-dozen presentations in the opening JavaOne keynote featured a few looks in the rearview mirror to honor Java's 20-year rise to become the dominate general-purpose computer programming language, but otherwise it was a pedal to the metal focus on new features in the various Java ME, Java SE and Java EE platforms. A familiar face from Java's past also made a brief and humorous video appearance to cap an eventful 2-hour session on Sunday, October 25, 2015 at Moscone Center in San Francisco.

Looking for a way to discover San Francisco while in town for JavaOne? Take the San Francisco Architecture Walking Tour. The 2.5 hour tour is led by Rick Evans, a local architecture expert. Learn about the historic buildings of San Francisco’s Financial District, while discovering hard to find rooftops gardens, and exploring landmarks. Additionally visit 4 of San Francisco’s Privately Owned Public Open Spaces (POPOS), the downtown area has 68 of them. Some points of interest include: 

  • The Hallidi Building known for it’s transparent glass wall. 
  • The Crown Zellerbach Paper Co first glass building built after the great depression and World War II.
  • The Shell building that was occupied by the Royal Dutch Shell oil company until the 1960s.

20 Years of Java: Developer Interviews Part 3

By David Lopez 

This year marks 20 years of Java! To celebrate, we wanted to get a feel for what Java and the Java Community mean to Java Developers, so this year at JavaOne Brazil, we asked them 3 Questions:

What’s your favorite moment as a Java Developer?
What’s your favorite thing about Java?
What do you think the future of Java is?

We recorded over 20 responses, each providing a unique insight into where Java could be heading and where they would like to see it go. Below you’ll find the final video in a 3-part series showcasing how the developers responded to the question: “What do you think the future of Java is?” We got all sorts of great responses, from the future of the IoT in your body to the importance of using tech for good, and of course, keeping the Java Community and User Groups strong seemed to be on everyone’s mind. If you can’t see it below, check it out here.
