Internet of Things (IoT) Hackathon in Brazil

SouJava is running a Raspberry Pi and Java hackathon at Campus Party, the week-long technology gathering of geeks, developers, gamers, scientists, and students in Brazil. Sponsored by Oracle Technology Network, the hackathon is designed for enthusiasts who want to create IoT projects with Raspberry Pi and Java. The objectives are for attendees to learn, practice, and innovative while creating an IoT project

Java evangelist Angela Caicedo opened the hackathon with an overview of IoT and Java development. Over two days, participants will build teams, brainstorm, attend training, get a kit from the organizers and hack on their own project. Onsite experts will be available to help participants. They are veteran Java developers of web, enterprise and embedded development. Among them are GlobalCode founder Vinicius Senger, senior developer Rubens Saraiva, SouJava leader Bruno Souza, Java Champion Yara Senger, product manager Bruno Borges and senior mobile developer Ricardo Ogliari

Gamification for User Groups

At the gamification session of the International Oracle User Group Community (IOUC), leaders discussed how to drive membership. Typically, they give away licenses, books and goodies to encourage attendance at monthly meetings. Others have used gamification to get their communities to brainstorm on mascot names, or post pictures and comments on social media. Hackathons also require the use of similar techniques to keep attendees motivated to create applications over several days. SouJava leader Bruno Souza successfully ran hackathons that combined brainstorming, team building, training, hacking sessions and prizes to keep participants engaged.

“Turn life into a game, drive engagement of audiences, make the experience more enjoyable and get users to come back ” are the key advantages of gamification according to user group leader Jim Bethancourt.

The forum platform Stack Overflow is a great example of running a thriving community of developers with its point systems. Contributors get rewarded with points for their useful entries and visitors easily find the most relevant and best-rated entries.

The ArabOUG has implemented a point system to keep its community active. The group gives out points to the members, who contribute applications, articles, and translations. It partnered with training organizations and other services to give its members free training and services in exchange for points. As a result, members don’t have to pay for services using online payments, which governments in many countries in North Africa and the Middle East don’t allow.

In an interview, ArabOUG leader Mohamed Chargui  explains in more detail his experience using gamification.

Java EE 8 Community Survey - Part 2!

By Guest BloggerDavid Delabassee 

The second part of the Java EE 8 Community Survey is now open!

During the last 5 weeks, we have been positively surprised by the community responses on the first part of the survey. We have received a lot of valuable feedback! That means we have *a lot of data* to process, a really nice problem to face! Thanks to all who participated in Part 1! If you haven't, there still time to answer Part 1.

Part 2 of the survey is focusing on topics such as Cloud, Security, Logging, Deployment, Testability, etc. We are again soliciting your feedback on those different topics.

In a few weeks from now, once the results of the 2 parts have been distilled and summarized, we will share those results with the community. The next step would then be to ask you to help us prioritize those features.

Thanks in advance for helping us to set the initial directions of Java EE 8 by participating in Part 2 of the Community Survey.

Hackergarten at Conferences

In this video interview, senior architects Andres Almiray and Swen Reimers discussed hackagarten event taking place during the conferences. "A hackergarten is group of people coming together for a couple of hours. We decide the open source projects we want to code on. It can be fixing a bug, adding a new feature, creating a screencast, testing features and giving feedback to the project. The goal is to contribute to an open source project" explained Andres.

Devoxx Hackergarten focused on Java EE Lambda projects this year. Swen was the project lead and mentor for the Lambda projects. Some of them worked on JavaFX and Lambda event threads. "We discussed why things would not fit in an API, the lambda syntax, and what is available or not" Swen mentioned. They are running hackergarten around the world. The next ones will be at JFokus, JavaLand and the monthly events in Basel, Switzerland.

Lego, Robots and Java!

In this video, Java Evangelist Angela Caicedo talked about her new Duchess robot built with Lego Mindstorm. "We are moving into the Internet of Things and I am looking for cool devices that we can connect and use Java" said Angela   

The robot is connected to touch and color sensors, has a gyroscope to orient and prevent it from falling, 2 motors for the wheels and another for arms, and an infrared sensor for the remote control.

Don't Miss Out at Devoxx!!!

Come by IoT Hack Fest which starts with the session: kickstart your Raspberry Pi and/or Leap Motion project, part II on Tuesday from 9:30am to 12:00pm to learn how to start a project with the Raspberry Pi and Leap Motion. In the afternoon, you can still join a project and create your own project with the help of experts on Raspberry Pi, Leap Motion and other boards. 

At the Oracle booth, Java experts will be available  to answer your  questions and demo the new features of the Java Platform, including Java Embedded, JavaFX, Java SE and Java EE. This year, the chess game that was first demoed at JavaOne keynotes last September will be showcased at Devoxx.

Hack Fest Going Strong!

Today was the first day of  the IoT Hack Fest at Devoxx, the Java developer conference in Belgium.  The IoT Hack Fest started with the Raspberry Pi & Leap Motion hands-on lab. Vinicius Senger introduced the Java Embedded, Arduino and Raspberry Pi. Java Champion and ZeroTurnaround Geert Bevin presented the Leap Motion, a controller sensing your hands and fingers to play games by controlling the mouse for example. "Programmers are cooler than musicians because they can create an entire universe using all senses" explained Geert

Participants started building applications in teams using Raspberry Pi, sensors and relays. One team tested the performance of Tomcat, Java EE and Java Embedded Suite on the Raspberry Pi. Another used built an text animation using a LCD screen. Some teams are using the Leap Motion to close and open programs on the desktop and others are using it as a game control.

Hands on with Oracle Java Cloud Service in Java Magazine

The latest issue of Java Magazine, which takes as its theme “Seize the Cloud,” has an article by IndicThreads founder Harshad Oak, titled “Hands on with Oracle Java Cloud Service, Part One,” that provides an introduction to Oracle’s platform-as-a-service (PaaS) Java offerings. PaaS is about renting a software platform and running a custom business application on it, thus enabling developers to focus on the business application and not have to worry about the hardware or core software platform, according to Oak.

Oak points out that, “Java EE has been the primary software platform for enterprise and server-side development for more than a decade, and it is increasingly the platform of choice even on the cloud.”

He explains that Oracle’s cloud push began in 2011, and has subsequently launched several cloud solutions that support more than 25 million cloud users worldwide. “Oracle Java Cloud Service and Oracle Database Cloud Service have been Oracle’s most visible PaaS solutions so far,” comments Oak. “Oracle’s other PaaS offerings are Oracle  Developer Cloud Service, Oracle Storage Cloud Service, and Oracle Messaging Cloud Service. Oracle Developer Cloud Service simplifies development with an automatically provisioned development platform that supports the complete development lifecycle. Oracle Storage Cloud Service enables businesses to store and manage digital content in the cloud. Oracle Messaging Cloud Service provides an infrastructure that enables communication between software components by sending and receiving messages via a single messaging API, establishing a dynamic, automated business workflow environment.”

All in all, the article examines the Java PaaS space and presents guidelines in selecting a Java PaaS service. It offers a basic description of Oracle’s Java PaaS solution—Oracle Java Cloud Service—and its capabilities. Looking ahead, Part 2 will go deeper into Oracle Java Cloud Service by showing how to develop and deploy a Java EE application on it.
