The final keynotes of JavaOne took place on Thursday, with the Intel, Technical, and Community keynotes. These keynotes cast strong glances both backward and forward at the platform and celebrated new technologies, especially related to the Internet of Things.
Intel Joins OpenJDK
Intel’s Michael Greene, vice president of system technologies and optimization at Intel’s Software and Services Group, took the stage and announced that Intel is joining the Open Java Development Kit (OpenJDK) community and will contribute math library functions that should boost big data analytics performance for machine learning.
Mark Reinhold appeared and briefly reprised his Technical keynote. Then Brian Goetz offered a vision of Java extending to Java 9 and beyond that would include value classes. Look to Project Valhalla and Project Panama for more information.
James Gosling Reflects on Java
Next, several Java luminaries—including the father of Java, James Gosling—took questions. After being asked if he regretted null pointers, Gosling quickly replied that he did not because all of the available alternatives at the time were far worse.
Gosling went on to explore why Java did not have generics from the beginning. Bill Joy, Java’s cofounder, wanted to include generics, a source of considerable conflict in 1994, but Gosling insisted that there was an insurmountable problem: Which generics do you use? Dozens of languages with generics already existed, and they all had problems. Gosling stuck to a basic principle he adhered to in creating Java: Never do the wrong thing.
When asked when Java would become obsolete, Gosling confessed that for a decade he has been expecting Java’s demise, but that Java is a kind of organism grounded in the community that is well understood and flexible and has strong staying power.
Later, Gosling reminisced about the origins of Java. “Everyone says that Java is approaching its 20th anniversary, but for me it’s the 25th,” he explained. He said that many Sun engineers were troubled in 1990 by the very primitive processors they saw in much consumer electronics—they thought the world was missing out. They took a long trip to Europe and Asia and studied primitive cell phones, elevators, lighting systems, and other gadgetry, and discovered that electrical engineers were needlessly reinventing old computer science problems. At the time, the internet was solid but not popular. Gosling credited Mike Sheridan, who was a business development person on the team, with inventing Java because he invented the reason for Java.
James Weaver: Java Show-and-Tell
Next, Oracle’s genial Java Technology Ambassador James Weaver took the stage, and reminded attendees that all sessions could be viewed on Parleys.com. A parade of talented developers and technologists followed.
Andra Kay, director at Silicon Valley Robotics, said, “By 2020 your household robot will be your house.”
Bruno Maisonnier, CEO at Aldebaran, a world leader in humanoid robots, presented a video showing robots teaching children mathematics in schools, and interacting with customers in stores. Maisonnier said that robots must (1) be cute, so that people enjoy them; (2) interact naturally in their body language and gestures; and (3) be easy to use.
Paul Perrone of Perrone Robotics lamented the 30,000 deaths from auto accidents each year in the United States, and showed a video about his automated vehicle testing system with an advanced braking system that could save lives—a first step toward cars with full autonomy.
