Now that I'm getting immersed in the conference circuit, I've got a new game to play every time I attend a session on any technology meant to ease the pain of client-side development. Based on the session abstract, I lay odds as to how long it'll take me to hear the presenter say something like this:

GWT 1.4 RC has been released. What's new? Just a sample: * Code generation is more efficient, maybe 10-20% smaller than in 1.3. * Improved loading code lowers load times by a third. * Lots of new widget enhancements, including the RichTextArea. Since a rich text editor seems to be a big requirement in lots of content managent apps, removing the need to drop in FCK or TinyMCE gets rid of a big debugging headache. * ImageBundle does the whole image concatenation thing for you. Basically, you glue all of your images into one image, and use CSS to clip just the image you want. That way you only have to do one image load instead of a few dozen for a image-rich app.

If you feel that DWR is a little too beefy for what it provides, then you might want to look at RAJAX (not to be confused with the Comet/Rajax that gets mentioned in DWR circles), a Java framework that does something similar, i.e. expose Java methods via Javascript proxies.

I've been hard at work on the next installment of my Echo2 tutorial series, which has been stalled at installment #1 (sorry about that). I decided that a nice, simple Sudoku program might be just the ticket for installment #2. Saturday was spent spelunking around, looking for some reusable Java Sudoku code. That was a bust. Everyone had their generator and solver glued to a GUI, and the actual generator code was fuggly. So the rest of Saturday was spent implementing an efficient puzzle generator.
