Using NASA's World Wind Component in Your Java Technology
World Wind is open-source software, developed by the National Aeronautics and Space Administration (NASA) that allows you to zoom from satellite altitude into any place on earth. But it's not just a toy. As the SDN article Using NASA's World Wind Component in Your Java Technology points out, "World Wind is a Java technology component that you can integrate into your applications to incorporate 3D earth modeling. World Wind does all the hard work for you, such as dynamic image selection and retrieval for images of the earth's topography. In addition, because the software is open source and written in the Java programming language, you can build into the NASA World Wind Java 3D visualization technology. You are also free to extend or embed the component architecture for business, research, or education. "

JSR-275 And why GeoTools does not care yet
The deadline for JSR275 is coming up on July 8th, as one of the top users of the JSR108 (which was withdrawn) you would think GeoTools would care about what is going on ... here is why we don't: Java 1.4 —  Jody Garnett

Firefox profiles - A very useful feature for web development
Firefox/Mozilla have a feature called profiles that allow you to run multiple instance of the browser in same windows/linux logon without clobbering each other. This can be helpful for testing multiple users/sessions simultaneously. It can also help you keep your normal settings safe from your web development. —  Bino George

Re: J2ME on BlackBerry
I must be looking at different information than you. Both the AT&T Dev site and the Blackberry site show that most of the Blackberries from the last two years on Cingular run Java. I have in my hand a Blackberry 8700 running on Cingular that runs Java. I have only tested this one device directly. But, you have to pay the extra money per month for the blackberry data plan. — 

Re: Develop in Java or not?
Java is, at the end of the day, a wrapper on top of natively compiled code so will not out perform well written C/C++ applications. However, in the real world, people rarely write well written code, but java helps promote good code through it's excellent APIs and IDEs. To the point that in many of our feasibility studies, Java performed noticeably better than it's C/C++ counterparts in desktop and server guises with reduced development time. — 

Re: Will JFileChooser be fixed for Java7?
Guys, the new file chooser in Netbeans 6.0 contains big improvements. To be clear, it still isn't perfect, but it provides filename auto-completion and the ability to drilling into a folder by hitting ENTER while it is selected. I'm hoping the Swing team will pick this up and fold it back into the JDK. Is there anything I can do to held make this happen?  —
