Bots for beginners
Having been in attendance for most of this year's Community Corner mini-talks, one thing that impressed me was how the robots on the other side of the booth were accurately simulated in the Greenfoot programming environment, as displayed in several mini-talks. Credit for this goes to the trackbot-greenfoot project , which allows you to try out the very simple trackbot API before downloading it onto a real device.
To get people interested in trying out trackbot programming and setting them loose in the maze, Shawn Silverman gave a daily mini-talk introducing the trackbots, their API, and the Greenfoot environment. The first of these is
today's JavaOne Community Corner Podcast . In
j1-2k8-mtT04: TrackBots, Greenfoot, and the RoboSim Contest: a How-To , Shawn
describes the basics of how to simulate a TrackBot using the Greenfoot environment. By the end of the session, attendees should understand how to use the robot's sensors to interact with the environment.
In Java Today ,
the Red Hat Magazine article Open source project: OpenJDK by Andrew Haley offers a history of the incorporation of OpenJDK into Fedora 9. "At the 2006 JavaOne conference, Sun announced plans to open source Java. This wasn
