Create Apps with the Gemalto Concept Board

"The Gemalto concept board has 2G and 3G support, so you can send text messages, place a call, write Java Midlets and Arduino shields support" explains Vinicius Senger.

In this video, he presents step-by-step tutorials on how to configure the Gemalto boards and to create a project controlling LED lights. You can download this project as well as the fan caller demo here. Visit the IoT Developer Challenge website for more training videos. Once you have a working project, submit a video and the code of your project for a chance to win a JavaOne trip! 

In the video below, Vinicius explains how to create a fan caller

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.
