Internet of Things Workshop for Kids

Devoxx4Kids is offering workshops for kids 6th grade and older to learn the basics of the Internet of Things in Mountain View, California on Sunday, May 4th. Register your child now for the morning or afternoon session!

These workshops will cover the basic concepts applied for interfacing the real world to the digital world, like sensors and controllers, circuits, voltage, current, analog and digital signals. Kids will learn via hands-on activities using the Arduino Uno, an open-source micro-controller. It can control simple components like switches, LEDs, and light sensors. Arduino kits will be provided for hands-on experience in a shared setting. 

The Internet of Things is growing each day. Objects from everyday life, like water heaters, energy meters, and weather stations are now connecting to each other and people, computers and the Internet. Now is the time for your child to learn about this exciting area!

Internet of Things for Kids

Sunday, May 4, 2014
9:00 AM to 12:00 PM or 1:00 PM to 4:00 PM

Hackerdojo, Mountain View, CA 

Price: $10.00/per person

REGISTRATION REQUIRED, no on-site registration. 

Note: Please download and install the software as described prior to the workshop.

Devoxx4Kids is focused on educating parents to teach their kids and show that it is possible to be creative with computers. The goal is to introduce parents and their kids to programming, robotics and engineering in a fun way. This is achieved by organizing sessions where attendees can develop computer games, program robots and also have an introduction to electronics.

Building Robots with Java Embedded

Join us for the new training on building robots with Java Embedded. This training is free and will be live on hangout or YouTube, Tuesday April 15 at 10:00am Singapore time; 7:30am India Mumbai; 11:00am Tokyo Japan; 2:00am UTC. Globalcode founder and embedded expert Vinicius Senger will focus on homemade robots and the Lego Mindstorms robots.

This training offers a chance to direct questions to top experts and get you started with your own project.  Once you have your own project ready, submit a video and the code by May 30 for a chance to win a trip to JavaOne 2014.

More resources and the support forum are available online. Learn about the Challenge rules.

The six month old virtual Java user group (VJUG) has now 1,200 members. London Java Community leader and technical evangelist Simon Maple created this user group so Java Developers could connect virtually. The group organized 10 sessions, all available online: 
  • Design is a Process, not a Document by Trisha Gee
  • Drive by Contributions A GitHub session by Brent Beer and Matthew McCullough
  • Don't be that guy! Developer Security Awareness by Markus Eisele
  • Getting Started with Java EE 7 by Arun Gupta
  • How To Do Kick-Ass Software Development by Sven Peters
  • 55 New Features in Java SE 8 by Simon Ritter
  • Comparing JVM Web Frameworks by Matt Raible
  • WebSocket Applications using Java EE 7 by Arun Gupta
  • Project Lambda: Functional Prog. Constructs and Simpler Concurrency in Java SE by Simon Ritter
  • Java 8 Parallel Streams Workshop by Stuart Marks

The purpose of the group is to provide content to developers who cannot attend JUG meetings. It will never replace the experience of a face-to-face meetup.  Simon is looking for ideas to best help existing JUGs.

Java and the Board Buffet

If you missed the IoT training session on Monday, we were at the Oracle Santa Clara campus diving into the world of computer boards. Embedded Expert Vinicius Senger talked to Principal Member of the Technical Staff, Gary Collins, and Java Architect Hinkmond Wong about the Raspberry Pi and other computer boards, IoT technologies and Java Embedded. 

Hinkmond sees Java well suited for Internet of Things because Java can handle complex programming with event processing, smart devices, cloud, and business intelligence. Hinkmond gave a tour of what was on his desk. He showed us Freescale i.MX6, Raspberry Pi, Hex bug, motion detector sensor, LCD screen, and a relay board. In his blog, he develops innovative embedded projects such as a Nest-like smart sensor to inspire developers to create their startups with Java.

You can visit other training sessions about Java Embedded and the Raspberry Pi. Enter the IoT Developer Challenge by May 30 for a chance to win a trip to JavaOne

Oracle Massive Open Online Course: Develop Java Embedded Applications Using a Raspberry Pi May 2014

Start Date: Monday May 19th, 2014

Based on the overwhelming response for the Java Embedded MOOC currently underway - we are offering the course again

Have you wondered what the future of embedded devices looks like?

Have you ever wanted to create your own weather station or design a device to control the lights in your home automatically?

All of these questions will be answered in this practical hands-on course. This course introduces Java developers to the world of embedded devices and the Internet of Things (IoT). Embedded controllers are already a part of our lives. Meters read electric and water usage and send the readings to a central office. Electronic thermostats turn on the heat and air conditioning as required.

Java Embedded leverages your experience with Java to open the world of the Internet of Things by providing direct access to electronic sensors and mechanical devices.

Presented by: Tom McGinn, Angela Caicedo, Jim Weaver, Simon Ritter

Learn How to Plug Into the Internet of Things

The Internet of Things is changing everything. From the way you start your day in the morning, to the way products are manufactured and cities operate their services, machines all around you will collect data, share it with each other, and use it to recommend and even make decisions along the way. 

When building solutions for the Internet of Things, you must ensure that devices, hubs and data centers connect effectively, that systems integrate easily, and that applications and analytics work together seamlessly. Join Oracle for this business-focused Online Forum with our partners and customers on Thursday, April 24 to learn how you can manage the complexity of the Internet of Things, and take advantage of business opportunities you haven’t yet imagined. 

A global network of billions of devices sharing data is opening up unprecedented business opportunities. How well positioned is your company to take advantage of this seismic shift?

WetClipserJ: A New Kind of Tool for Java Developers

Oracle is proud to announce a brand new category of tool for developers: an Integrated Development Environment. WetclipserJ is not just a code editor, but a super code editor! "This is an area that's been previously unexplored, and we know developers are going to love it," said Lead Evangelist Peter Redienhcsztu. 

WetclipserJ provides code analyzers, sizers, and editors for working with all the latest technologies. It also has a range of new enhancements--which is pretty remarkable, considering this is the first release.  

"I went to Google to figure out what to work on next, and it started finishing my queries for me, so I thought, maybe you can do the same thing with code!" explained Imperial Grand Chief TopGuy Mark Dlohnier. "I went to take out my trash," said Engineer Architect BuilderGuy Brian Ztoeg, "and thought…nevermind." Director John Illeraccec-Noilluj expects adding functionality to this new tool in later releases, such as code templates, coding tips, and refactoring tools. Perhaps even deploying to an app server with one click! Wisely, WetclipserJ only supports Java. Multi-language support just doesn't make sense in a world where developers rarely use more than one language. "I say, pick the best and you stick with it!" exclaimed Illeraccec-Noilluj.

"We like to call this new type of tool an I-D-E, but it may take a while for that acronym to catch on." Redienhcsztu explained.

See what these community members say about WetclipserJ:

"It's great to see Oracle listening to the developer community with regards to developer needs...but what about *my* needs?"
-Martijn Grubrev

<head slap>"Why didn't I think of that?"
-Mattias Nosslrak 

"Dare I dream for a performance analyzer in this tool?"
-Kirk Enidreppep

"Developers are hungry for a tool is so advanced it requires hours of specialized training."
-Yara Regnes  

"If you get the virtual plug in, make sure you get the training, I swiped at a fly and accidentally wiped out hours of work." 
-Bruno Azuos
