JavaLand4Kids Celebrates A Successful Premiere!

14 boys and girls of 3rd and 4th grades discovered that programming is easy during JavaLand4Kids. "For the children it was really a great experience and it was great to see how much fun they had exploring" explained Jörn Diercks, one of the teachers.  

In one workshop, girls and boys learned the programming language "Scratch", which has a graphical user interface. This language uses colored blocks that can be dragged & dropped to program sounds, images, movements and more. This allowed young developers to quickly learn the basics of programming and to develop their first games.

In a "QuadroCopter" workshop, children controlled a drone that was programmed specifically for this event. After they learned the basic commands, they were able to complete many maneuvers. The girls and boys also showed great interest in the electronics kit "TinkerForge". The electronic components can be combined with Legos. 

“From now on, JavaLand4Kids is going to be an integral part of the JavaLand Conference. So, this is a call to arms for my friends and speakers” commented Markus Eisele, who is the one of the organizers of JavaLand.  Visit his blog for more details. Get in touch with Markus if you want to get involved with the next JavaLand4Kids.

New Java Champion Martin Thompson

Congratulations to the new Java Champion Martin Thompson 

Martin is a consultant, trainer, and coach specializing in designing high-performance and low-latency systems. In the performance space, he has changed expectations about what is possible with Java by showing that Java can compete with and even outperform native applications. His passions include concurrent programming (the Disruptor being one of his creations) and teaching people how to write algorithms that best utilize modern hardware. He started the Mechanical Sympathy blog and forum, a popular forum of high-performance systems to get guidance for understanding the implications of running their code on modern hardware and for producing code that works in harmony with hardware to be significantly more efficient and robust. Follow Martin on Twitter @mjpt777

Martin is a very active open source contributor. He wrote the initial release of LMAX  Disruptor, an inter thread event processing framework, which won the Duke Choice Award. He also contributed to Aeron, a high throughput, and low latency message transport, surpass native C/C++ implementations by the top commercial vendors in the financial trading space. He contributed to SBE, a message codec that is typically 20X faster than Google Protobufs. 

Martin is a frequent presenter at global conferences. His techniques in high-performance application development have become a standard in every low latency industry and have influenced millions in finance, gaming, and everywhere that high-performance is required.

Two Live Streaming Java Sessions from vJUG

The vJUG, a virtual Java user group, presents live streaming technical sessions about topics related to Java, JVM, Java EE, Internet of Things and more. Organized by Mani Sarkar and Simon Maple from the London Java Community, their aim is to get the greatest minds and speakers of the Java industry to give talks and presentations in the form of webinars and live streaming from JUG meetups.

First session: How is Java/JVM built?  Tuesday, March 24, 2015 at 14:45 UTC, 15:45 in Germany, 10:45am in New York, 7:45am in San Francisco, and 22:45 in Beijing

Mani Sarkar and Daniel Bryant will give an overview of the Adopt OpenJDK program. They’ll explain why developers should get involved, how to participate, and how front-end developers can take advantage of the Adopt OpenJDK. Watch the session live at http://nighthacking.com/event/javaland-2015/

Second session: What's coming in Java.Next? Wednesday, March 25, 2015 at 14:45 UTC, 15:45 in Germany, 10:45am in New York, 7:45am in San Francisco, and 22:45 in Beijing

Learn from Heather VanCura how you can take part in Java technology by Adopting a JSR. This session give a brief overview of the Adopt-a-JSR program. Andres Almiray will discuss JSR 377, Desktop|Embedded Application API; Anatole Tresch will discuss JSR 354, Money & Currency API; and Ed Burns will discuss the two JSRs he is currently leading, JSR 369, Java Servlet 4.0 Specification and JSR 372, JavaServer Faces (JSF 2.3) Specification.

Two sessions are scheduled for next week. They are live from the JavaLand Conference in Germany, in partnership with the Nighthacking community.  You can watch them online at http://nighthacking.com/event/javaland-2015/

Minecraft Modding Course at Elementary School - Teach Java to Kids

By Guest Blogger Arun Gupta

Cross posted from weblogs.java.net/blog/arungupta/archive/2015/03/22/minecraft-modding-course-elementary-school-teach-java-kids

Exactly two years ago, I wrote a blog on Introducing Kids to Java Programming using Minecraft. Since then, Devoxx4Kids has delivered numerous Minecraft Modding workshops all around the world. The workshop material is all publicly accessible at bit.ly/d4k-minecraft. In these workshops, we teach attendees, typically 8 - 16 years of age, how to create Minecraft Mods. Given the excitement around Minecraft in this age range, these workshops are typically sold out very quickly.

One of the parents from our workshops in the San Francisco Bay Area asked us to deliver a 8-week course on Minecraft modding at their local public school. As an athlete, I'm always looking for new challenges and break the rhythm. This felt like a good option, and so the game was on!

My son has been playing the game, and modding, for quite some time and helped me create the mods easily. We've also finished authoring our upcoming O'Reilly book on Minecraft Modding using Forge so had a decent idea on what needs to be done for these workshops.

Minecraft Modding Workshop Material

All the workshop material is available at bit.ly/d4k-minecraft.

Getting Started with Minecraft Modding using Forge shows the basic installation steps.

These classes were taught from 7:30am - 7:45am, before start of the school. Given the nature of workshop, the enthusiasm and concentration in the kids was just amazing.

Java 9 and Beyond

In his keynote at EclipseCon last week, Chief Java Architect Mark Reinhold talked about the main features of Java 9. It will introduce modularity to create a scalable and more secure platform.  The flexibility of modules will allow developers to use just a small part of SE, whether they are constrained by a small device or multiple virtual instances in a cloud environment. 


There are four main JEP (JDK enhancement proposal) for Java 9, which are: 

- JEP 200 defines the modular structure

- JEP 201 modularize the source code

- JEP 220 introduced modular runtime images

- The last JEP will be delivered hand in hand with JSR 376 introducing the actual module system for the Java platform.

There are two projects about features beyond Java 9. Project Valhalla is about value types, generic specialization and Var handles. Project Panama is about a foreign function interface (FFI), data layout control and Arrays 2.0
