Register today for the Oracle Java ME Embedded MOOC!

By Guest Blogger Tom McGinn 

We are pleased to announce that the Oracle Massive Open Online Course: Develop Java                             Embedded Applications Using a Raspberry Pi is open for enrollment.

The course will start March 31st!

Enroll

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.

This free course, designed for Java developers, is delivered over 5-weeks. Take the course                                       at your own pace - weekly we will add new lessons, quizzes and homework assignments.

You will work on a real-world application to:

  • Read input data from switches and drive LED's using the GPIO interface
  • Read temperature and barometric pressure from an I2C device
  • Read the device's current location using a GPS UART device
  • Store and manage data collected
  • Report data to a client through a variety of communication options
  • And more!

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.

An Overview of Batch Processing in Java EE 7

Up on otn/java is a new article by Oracle senior software engineer Mahesh Kannan, titled “An Overview of Batch Processing in Java EE 7.0,” which explains the new batch processing capabilities provided by JSR 352 in Java EE 7. Kannan explains that “Batch processing is used in many industries for tasks ranging from payroll processing; statement generation; end-of-day jobs such as interest calculation and ETL (extract, load, and transform) in a data warehouse; and many more. Typically, batch processing is bulk-oriented, non-interactive, and long running—and might be data- or computation-intensive. Batch jobs can be run on schedule or initiated on demand. Also, since batch jobs are typically long-running jobs, check-pointing and restarting are common features found in batch jobs.”

JSR 352 defines the programming model for batch applications plus a runtime to run and manage batch jobs. The article covers feature highlights, selected APIs, the structure of Job Scheduling Language, and explains some of the key functions of JSR 352 using a simple payroll processing application. The article also describes how developers can run batch applications using GlassFish Server Open Source Edition 4.0.

Kannan summarizes the article as follows:

“In this article, we saw how to write, package, and run simple batch applications that use chunk-style steps. We also saw how the checkpoint feature of the batch runtime allows for the easy restart of failed batch jobs. Yet, we have barely scratched the surface of JSR 352. With the full set of Java EE components and features at your disposal, including servlets, EJB beans, CDI beans, EJB automatic timers, and so on, feature-rich batch applications can be written fairly easily.”

JavaFX Open Source Update!

Oracle has started to open source JavaFX, the rich client platform for Java applications. The list of open sourced projects will be growing in the next couple of weeks with an additional 7 projects. "We are also going to open source our iOS and Android implementations over the next couple of months" announced Richard Bair, architect of the JavaFX platform, in his blog.

Open Data, Government and Transparency

A new track at TDC (The Developer's Conference in Sao Paulo, Brazil) is titled Open Data. It deals with open data, government and transparency. Saturday will be a "transparency hacker day" where developers are invited to create applications using open data from the Brazilian government.  Alexandre Gomes, co-lead of the track, says "I want to inspire developers to become "Civic hackers:" developers who create apps to make society better." It is a chance for developers to do well and do good. There are many opportunities for developers, including monitoring government expenditures and getting citizens involved via social networks.

The open data movement is growing worldwide. One initiative, the Open Government Partnership, is working to make government data easier to find and access. Making this data easily available means that with the right applications, it will be easier for people to make decisions and suggestions about government policies based on detailed information. Last April, the Open Government Partnership held its annual meeting in Brasilia, the capitol of Brazil. It was a great success showcasing the innovative work being done in open data by governments, civil societies and individuals around the world. For example, Bulgaria now publishes daily data on budget spending for all public institutions.
Alexandre Gomes Explains Open Data

At TDC, the Open Data track will include a presentation of examples of successful open data projects, an introduction to the semantic web, how to handle big data sets, techniques of data visualization, and how to design APIs.

The other track lead is Christian Moryah Miranda, a systems analyst for the Brazilian Government's Ministry of Planning. "The Brazilian government wholeheartedly supports this effort. In order to make our data available to the public, it forces us to be more consistent with our data across ministries, and that's a good step forward for us," he said. He explained the government knows they cannot achieve everything they would like without help from the public. "It is not the government versus the people, rather citizens are partners with the government, and together we can achieve great things!" Miranda exclaimed.

Saturday at TDC will be a "transparency hacker day" where developers will be invited to create applications using open data from the Brazilian government. Attendees are invited to pitch their ideas, work in small groups, and present their project at the end of the conference. "For example," Gomes said, "the Brazilian government just released the salaries of all government employees and I can't wait to see what developers can do with that."
