Thursday at Oracle OpenWorld marked the last day attendees could enjoy and absorb the show’s many sessions, demos, and hands-on labs. It also offered a final opportunity to amble through the canopy-covered Cloud Lounge on Howard Street—a perfect spot to sit and recover from a late night at Wednesday’s Oracle Appreciation Event, which featured headliners Sting and Gwen Stefani. This year’s concert moved from Treasure Island to AT&T Park—home of the 2010, 2012, and 2014 World Series Champion San Francisco Giants. Sting and Stefani certainly did the Giants proud, dazzling the crowd with separate high-energy sets and an electrifying duet of a timeless classic from Sting’s Police days, “Message in a Bottle.”
Also wrapping up Thursday was the JavaOne conference—the premier conference for developers who want to learn from the luminaries in their field and celebrate the world’s most popular programming language. This year’s JavaOne keynote highlighted the ways scientists are using “write once, run anywhere” Java code today.
Benjamin Wolff, staff software engineer for CERN, the European Organization for Nuclear Research, discussed CERN’s large hadron collider (LHC)—which, with its nearly 17-mile circumference, is the largest machine ever built. Wolff shared how the LHC’s Java-based Accelerator Control System orchestrates more than 100,000 devices with more than 2 million I/O endpoints.
“We’re speaking about a massive system involving more than 10 million lines of code, split over 1,500 Java artifacts,” said Wolff, who shared the stage with Oracle’s Georges Saab, vice president of development for the Java Platform Group; Anil Gaur, group vice president of engineering for the Cloud Application Foundation; and Sharat Chander, principal product manager for Java product management.
For the third year, JavaOne also hosted JavaOne4Kids, a daylong series of computer science workshops for 450 children, 300 of whom come from underserved schools. Workshops covered such topics as assembling gadgets powered by Arduino boards, coding games and websites, and learning Java through technologies such as Greenfoot, Alice, Scratch, and BlueJ.
And while the kids tried future careers in development on for size, several hundred adults got to indulge their inner child at Stephen Chin’s Java Community Keynote, which closed out the conference. Chin, Java community manager at Oracle, hosted—or rather battled—Darth Coder and the Duke Troopers as they attempted to steal modules from developers across the galaxy. Attendees helped save the Java 9 release from the evil clutches of the Imperial Army, all while discovering how Java enables technology in drones, robots, games, and the cloud.
