Re: J2SE 5.0_05 has significant performance improvements
I just noticed something with 1.5.0_04. I'm not sure how long this has been around but I think it's way cool. I ran the swingset demo on my windows xp machine and also launched the windows task mgr. I was surprised to see what happened when I minimized the demo. The memory it was using dropped from 30 megs to 1 meg and stayed there. I know what you're thinking. If I restore the window, I'll have to watch it slowly repaint.....Wrong. It restores perfectly without any delay to user interaction. By the way, I noticed that internet explorer behaves the same way. Am I crazy or is this a new performance feature? Having multiple java desktop apps running at the same time looks possible now. —
Re: Java2D font rasterizer status
Basically we implemented an MS extension to the TrueType standard that MS implemented and used in a couple of key fonts. That was the major fix. There are still some open issues for us to pursue. Definitely issues in key UI fonts such as Tahoma, Microsoft Sans Serif, and the C* fonts (I forget all their names) that are coming up in Vista will be of particular priority. Very specific reports of point size (indicating java or native size) and font and O/S platform help a lot. PNG images help even more .. —

New Splash-Screen Functionality in Mustang
One desirable trait of a desktop application's "splash screen" is to come up as early as possible, providing feedback about the application's startup and to hold the user's attention for a second while the app initializes. You can do this with Swing, but then you have to wait for both the JVM and Swing to load and initialize. Another option is coming: according to the SDN article New Splash-Screen Functionality in Mustang, Java SE 6 "provides a solution that allows the application to show the splash screen much earlier, even before the virtual machine starts. Now, a Java application launcher is able to decode an image and display it in a simple nondecorated window ."
What Is Open Source
"Answering the question 'What is open source?' used to be a lot simpler than it is today." Open Source for the Enterprise author Dan Woods says that open source software is usually released under licenses "that ensure that the source code is available to everyone to inspect, change, download, and explore as they wish." Usually. Things have gotten more complex, and in What Is Open Source, Dan explores what the term now means, and whose definitions are different.
