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/

Nighthacking at JavaLand

By Guest Blogger Stephen Chin

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!

Catch the action at http://nighthacking.com/, and follow the NightHacking Twitter handel for late-breaking updates.

Schedule (Time Zone is CET)

Announcing Java SE 8 Update 40

Improved performance, scalability and administration in Java SE 8 Update 40 will allow Java developers to innovate faster and improve application services. Here are some features and changes including JavaFX updates: 

JVM Reaction to Memory Pressure: “Memory pressure” is a property that represents the total memory usage (RAM) on the system. This new feature can be leveraged to reduce the amount of memory used on a system where multiple JVMs are deployed and control the amount of memory designated to be consumed by each JVM, avoiding Out of Memory Errors (OOMEs) from occurring.

Improvements to the native packager: Enables developers to create native-feel applications that do not require clients to have an existing Java Runtime installed. These self-contained applications can then be deployed into areas like the Mac app store. The application developer has full control over the runtime and application entry points.

Ability to modernize the JavaFX stack on Mac OS X: The JavaFX media stack has been ported on Mac OS X® from QTKit and Quicktime, which have been deprecated, to the newer AVFoundation framework. With this, developers using the JavaFX media stack can now gain Mac App Store acceptance and have the opportunity to have their applications released on the Mac App Store. 

Nashorn Support: Numerous Nashorn optimizations including support for dynamic languages are incorporated into this release. Also added is a Nashorn Class Filter, which provides fine-grained control over access to Java classes from JavaScript code via a new filtering interface. 

New Time Zone Date Updater Tool: This tool can consume the ‘raw’ time zone data (tzdata) rules from the IANA time zone registry database and convert those to the necessary format required by the JRE. This provides users with the ability to immediately update the JDK/JRE time zone rules with the latest updates from IANA.

Voxxed, a New Java Portal!

In this interview, Mark Hazel and Lucy Carey discuss a new Java knowledge sharing platform called Voxxed. The website is a “concentration of outstanding content from conferences. It includes tutorials, articles, blogs, and interviews” explains Mark. The topics cover the entire Java ecosystem: JVM, methodology, cloud, future, and mobile.Visit Voxxed.com

JVM News from the JVMLS!

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.

Java Magazine: The Java Virtual Machine

by Caroline Kvitka, Java Magazine Editor in Chief

The July/August issue of Java Magazine explores the Java Virtual Machine (JVM), and includes a JavaOne preview. While often overshadowed by the Java language, the Java Virtual Machine is the cornerstone of the Java platform. It gives Java its hardware and operating system independence, small compiled code size, and protection from malicious programs. We’ve dedicated almost an entire issue to the JVM, so if you haven’t paid much attention to it lately, buckle up and get ready for the ride.

One of the most notable things about the JVM is that it can run hundreds of programming languages besides the Java language—providing developers with flexibility and freedom of choice. In our cover story, “Alternative Languages for the JVM,” Raoul-Gabriel Urma takes a look at eight JVM languages and some of the benefits of using them. In “Performing 10 Routine Operations Using Different JVM Languages,” Venkat Subramaniam further explores the benefits of alternative languages—while also showing how Java SE 8 handles certain tasks. Developing JavaFX applications? Check out Josh Juneau’s article, “JavaFX with Alternative Languages,” to discover how alternative languages and custom APIs can speed development. 

We also focus on things you can do to make the JVM work better for you. Julien Ponge shares advice on avoiding benchmarking pitfalls on the JVM, and Cas Saternos gets us up to speed on server-side deployment on the JVM. In addition, Marcus Hirt introduces us to a profiling and diagnostics tool for Java applications running on the JVM and Ben Evans gives us a primer on just-in-time compilation.

Want more? Make sure to register for JavaOne, September 28–October 2 in San Francisco, California, which features a dedicated JVM Languages track (and check out our JavaOne conference preview [with speaker previews and coffeeshop recommendations]).

Java Magazine is a FREE, bi-monthly, online publication. It includes technical articles on the Java language and platform; Java innovations and innovators; JUG and JCP news; Java events; links to online Java communities; and videos and multimedia demos. Subscriptions are free, registration required.

Java Rocks More Than Ever

In a series of blogs full of technical detail and cross-platform comparison, senior developer Geert Bevin from ZeroTurnaround gives 10 reasons why Java is a great technology. He built software for musical instruments using C++, with Juce Library and CPython, and realized that he missed a lot from the Java ecosystem.

He has written the first six blogs, which include Java Compiler, the core API, Open Source, the Java Memory Model, HighPerformance VM and Bytecode. In his first blog about Java Compiler, he gives examples and recommendations on how to use the JVM's just-in-time, the compiler code versus the architecture, runtime rather than static or dynamic linking. 

Upcoming topics include: 
Intelligent IDEs
Profiling Tools
Backwards Compatibility
Maturity With Innovation
