Telit and Java ME Embedded 8

By Terrence Barr, from his original blog

In case you missed it, Telit and Oracle last week published a customer solutions brief titled:

Telit Brings Internet of Things Technology Faster to the Automotive Market and Other Industrial Sectors Thanks to Embedded Software Platform

Key quote:

“Oracle Java SE Embedded and Oracle Java ME Embedded are the perfect platform for our 3G and 4G wireless IoT communication modules. “

Java ME Embedded is especially well suited for enabling robust and secure intelligence on the edge in resource-constrained or deeply embedded devices and is being successfully adopted across a number of use cases and industrial sectors, from remote monitoring and industrial control, to automotive and M2M communications.

About the Latest Issue of Java Magazine!

How are engineers changing the way they test applications? This new issue of the Java Magazine focuses on test-driven development. Some companies like Atlassian are moving the quality assurance responsibility entirely to developers.  The advanced features of JUnit, a simple framework to write repeatable tests, can greatly increase developer testing abilities. User interfaces require specialized testing tools; for example, TestFX is designed to test JavaFX applications. Browser based applications can be tested with Selenium against multiple web browser types and versions.

The articles about testing are:

  • Test JavaFX apps with TestFX 
  • Eight Greatly Underused Features of JUnit 
  • Building and Automating a Functional test Grid 
  • Stress Testing Java EE Applications 
  • Think Like a Tester and Get Rid of QA 

In addition, you will find the articles about: 

  • Kotlin: A Low Ceremony, High-Integration Language 
  • Functional Programming in Java 
  • Contexts and Dependency Injection 
  • A First Look at Microservices 
  • More Ideas to Boost Your Developer Career 
The magazine is available for free!

Geek Bike Ride before JavaOne 2015

Again this year, the Silicon Valley JUG invites you to the annual Geek Bike Ride the Saturday before JavaOne (Oct 24 8:30am - noon). You will start at Pier 41 in Fisherman's Wharf and ride across the bridge and down into Sausalito, and then take a ferry back to the city. Ride starts at 8:30am so folks can get back for other JavaOne activities. (You'll make it back for sure by 12:00).

This is a beginner/intermediate ride, roughly 8 miles and takes 1.5 hours to ride. In the plan are several photograph stops, and a stop for a treat in Sausalito. There are three big hills (two steep ones going up Fort Mason and the approach to the bridge, and one fun downhill into Sausalito), but (obviously) the bridge is flat and easy. The hardest part may be dodging pedestrians on the bridge! 

All geeks and their friends are invited. Meet at Blazing Saddles bikes at Pier 41 in Fisherman's Wharf at the Blue & Gold Fleet Sausalito/Tiburon Ferry Terminal. If you want to reserve a particular bike, you can reserve it in advance online (even electric bikes!) Bike rental is $30-$40 USD and there's a 10% discount if you reserve online.
The Blue and Gold ferry from Sausalito is $10.50 USD. They are used to having bikes on board.

Transit and parking info: You can take the Historic F Line Street Car to Pier 41 to Blazing Saddles Bike Rental. Parking garages are at Fisherman's Wharf.
Wear your Java Geek bike jersey if you have one!

Sign up on the  Google+  Geek Bike Ride page. If you have trouble seeing the event, email SV JUG organizer Kevin Nilson at kevinATjavaclimberDOTcom.

Perspectives on Java Evolution!

To mark twenty years of innovation, the May/June issue of Java Magazine interviewed Mark Reinhold, chief architect of the Java Platform Group at Oracle. Reinhold described what has surprised him most about Java's evolution, discussed the importance of retaining the "feel of Java," and offered his opinion on Oracle's stewardship of Java during the interview

He also explained the recipe for how Java evolves: identifying a pain point, figuring out what abstractions are missing, and then adding those abstractions. With that recipe in mind, he discussed the two pain points that Java SE 9 will address: Java is a huge, monolithic platform and large applications tend to be brittle. Both pain points will be addressed in Java SE 9 with a common solution: modules.

In addition, Reinhold discussed his career and day-to-day activities, and he offered some advice to novice developers. Read the interview here.

Java ME Embedded 8.2 Release!

This release expands security functionality and robustness of the runtime, enables new and improved connectivity features, enhances deployment options and brings several highly effective optimizations to the Virtual Machine and core libraries. Released at the same time is Java ME SDK 8.2, which is now delivering the embedded development experience to Linux users.

Part of Java 8, Java ME Embedded 8 is a complete runtime client, optimized for ARM architecture and other resource-constrained systems. It is designed for low-power, limited memory devices requiring support for a range of network services and I/O interfaces.  

Alex Belokrylov wrote a detailed blog about the features of this release. In addition, here are some links for more information:
