“Building Block for the Internet of Things”, Nandini Ramani, VP of Java Product Development, Oracle
Get a new perspective on how enterprises may generate value from IoT and what it takes to make IoT work. Learn about key building blocks for IoT solutions. Get an overview of how Oracle’s products, including Java, enable end-to-end IoT deployments.
“Turning Devices into a Value-Generating Application Platform with Java”, Axel Hansmann, VP Strategy and Marketing Communication M2M, Gemalto
Learn about Gemalto’s vision for the future of IoT, strategy using Java, and adoption plans for Java ME 8. Find out more about Gemalto’s technologies and how they are used, from quick IoT/M2M prototyping to full-scale enterprise solutions.
I’ll be pointing out more interesting videos and content over the next couple of weeks.
The first instance of the Massive Open Online Course (MOOC) “Develop Java Embedded Applications Using a Raspberry Pi” is currently underway.
The response has been overwhelming and we had to cut off registrations and put people on the wait list. So we are now announcing a repeat of the course starting May 19th, 2014 to give all of you who missed it the first time around another opportunity. Enroll now before space runs out again. It’s still FREE.
Here is the next Java ME 8 Developer Drop, b58. As before, this is provided “as is”, with no guarantees of stability or functionality.
To access, go to the EA #2 downloads page and look for “latest developer build”:
Oracle is running the “Internet of Things (IoT) Developer Challenge” until May 30th, 2014. Submit a video and the code of your cool project, and you may win a trip to JavaOne 2014, a laptop, or other great prizes!
Don’t know where to start? Oracle is also providing free live sessions and online training running through April to help you get going. For example, next Monday (April 7) at 6:00pm UTC the session is about the “Internet of Things, Java and Raspberry Pi”. Plus, there is more help via online forums and other resources.
Find out all about the IoT Developer Challenge at The Java Source blog.
Jim Connors published a great blog post a little while ago, describing the benefits of using the new Java SE 8 language and API features on multicore embedded systems like the Boundary Devices BD-SL-i.MX6 (built around the Freescale i.MX6 quad-core architecture).
As you can see in the above diagram, leveraging parallel Java SE 8 Lambda and stream operations can dramatically improve overall performance. What’s more, the effort on the part of the developer is minor and the resulting Java code is portable and scalable across all Java SE 8 platforms, including completely different underlying architectures such as ARM on Linux vs. x86 on Windows.
Compare that to a traditional embedded multicore application, which typically is built with specialized frameworks, knowledge, and tuning and results in platform-specific code with limited portability and scalability. Plus, potentially hard-to-find multithreading bugs …
Out-of-the-box multicore support is another great example of why Java Embedded makes a lot of sense for embedded solutions.
I just posted an expanded and updated Java ME 8 Deep Dive slide deck on SlideShare.
(apologies for the partially messed up colors and slides, SlideShare is going that during the conversion process ;-( )
The current March/April issue of Java Magazine is chock-full with embedded content:
- From Smart Grids to Microbrews: Using Java ME 8 to manage utilities infrastructure AND to brew beer
- Java ME 8 and the Internet of Things: Top features of Java ME 8
- New to Java? How to become and Embedded Java Developer in Minutes
- JavaFX and Near Field Communication on the Raspberry Pi
… along with lots of other great Java content, especially related to this week’s launch of Java 8.
PS: For more info on the beer-brewing use case, see the screencast “Developing Modular, Service-enabled Applications: Java ME 8” (go here and scroll down to see the screencast under the “Java ME 8” section).
Java Magazine is free, but requires registration. Enjoy!
Java 8 is officially launching today!
Along with todays live launch event there will be lots of new information available such as a set of brand-new screencasts:
Java ME 8 is a key part of the Java 8 launch and will be available soon. Until then, there’s plenty to get started – for example, the Java ME 8 Early Access. Or check out the new Java ME 8 screencasts:
- Be an Embedded Developer in Minutes using Java ME 8
- JSR 360 – CLDC 8: Benefits of an Optimized Implementation
- JSR 360 – CLDC 8: Java Platform for IoT
- JSR 360 – CLDC 8: Generic Networking APIs
- Unified Development Experience for Java ME 8 and Java SE 8
- Accessing H/W Devices using Java ME 8 Device I/O API
- Java ME 8: Top 10 Features
- Java ME 8: Tackling the Challenges of Embedded Software Design
- JSR 361 – MEEP 8: A New Java Profile for the Embedded World
- Developing Modular, Service-Enabled Applications with Java ME 8
Lots to learn. Exciting times.
I’m excited to be on my way to JavaLand, the brand-new German Java Community Conference. Will be speaking tomorrow, March 26 at 2 pm, on the topic of “Desktop to Internet of Things in 12 Seconds”.
Should be a great conference & hope to see you there!
I totally forgot to post this announcement by Gemalto and Qualcomm from CES. Yes, it’s a few weeks old, but it has not lost any of its relevance. Quite the opposite … with the Java ME 8 release coming up soon, the momentum is building:
“Gemalto launches next generation M2M product range adding Oracle Java ME 8 solutions capability based on chipsets from Qualcomm Technologies”
For more information, see the Gemalto press release.
