JavaOne 2007
Lets summarize the most interesting things about JavaOne 2007 while the memories are still fresh. It was one of the busiest and most enjoyable conferences for me. One of the important trends this year is moving the entire platform to the Open Source. Java as a platform has always been one of the major foundations for the open source projects, clearly a leading development platform with very diverse and numerous projects build on top of JEE and SE. With SDK itself now open source as well, the number of opportunities even greater. Java 6 is also a technological leap forward with much richer set of tools and components. I had a chance to experiment with it quite a bit and my my personal experience with it nothing short of amazing. With first JDK beta announcement in December of 1995 this is the 12th anniversary. It created huge industry with every major vendor having stake in it. But the future opportunities are even greater. Java is a the major platform for mobile devices which clearly future of computing with mobile devices outselling PCs 20:1.
I was thinking about interesting way to present the success formula for the most synergistic set of technologies and came out with this: (Java + Linux) * GPL'ed software. Your millage may very, but I find this set of technologies the most relevant and dynamic for moving forward. There is of course a number of others, but they usually occupy a niche, while Linux in Java are everywhere from cell phones and micro controllers to server farms, clusters and grids. Java is also embracing emerging languages , you can run high productivity languages such as Python and Ruby natively on JVM.
I finally got “aha” on the convergence of 3D technologies into something that may be the desktop and collaboration tool of tomorrow. The environmental challenges, commute and globally distributed teams present interesting set of problems where 3D desktop with virtual working environment may offer a solution to allow people much easier to work together and remain productive and connected (including socially). You can finally have a water cooler conversation with your coworker from thousands miles away :-) , but most importantly have a meeting and share documents and the more natural(although virtual) three dimensional environment. Java 3D Desktop looked like a cool toy few years ago, now combined with virtual world (Wonderland Project) and communication channel (Darkstar) it shapes itself into much more powerful, interactive and very advanced collaboration platform. You can also start building 3D applications while continue to use traditional 2D ones.
It would likely to take hours do describe every other interesting piece of information from the conference, instead here is list of highlights by a category with links:
