JavaOne: Day 2
Gavin King’s packed Web Beans technical session
Monday’s CommunityOne crowd was manageable and pretty much what I expected. Tuesday’s crowd was larger, but I walked straight into the technical sessions without a problem. This morning I stepped outside for a few minutes, and when I came back in, there was a line stretching across the entire large hallway and down an adjacent narrow one. Then I realized that was the line I wanted to be in.
At the end of that long (but quickly moving) line, Gavin King from JBoss spoke to a standing-room-only crowd about the basics of Web Beans. The presentation included a lot of example code, stepping everyone through binding types, deployment types, producer methods, and more.
If you’re interested in hearing Gavin yourself, we have a video interview of him talking about Web Beans .
Mapping Mars
This afternoon, I went to hear Saadat Anwar, Scott Dickenshield, and Eric Engle talk about JMARS
, which is an open source Java application for working with Mars data. As of April 30, 2008, it is licensed under GPLv3. It’s a vital part of the planning process for NASA’s Mars satellites, and anybody who wants to can freely access both the pretty pictures and the cold, raw data.
JMARS began as a targeting tool for THEMIS and the HiRISE mission. Now it’s a GIS browser, and from the demo I saw, the mapping looks pretty nice. To solve the eternal mapping problem of round planet, flat screen, they wrote their own project code and built a custom WMS map server capable of ingesting their standard data formats and returning only the necessary part of the image, which means getting a few megabytes instead of terabytes.
Those interested in getting involved or just digging into the code can find the project at oss.mars.asu.edu/trac and oss.mars.asu.edu/svn . If you’re a teacher or have kids, you might be interested in the Mars Student Imaging Project . They’ve also consolidated a lot of the relevant links at http://jmars.asu.edu/javaone2008 .
