Perfomance regressions: I was wondering this morning if it might make sense to write unit tests to verify performance of specific operations. The basic idea is that we have a unit test that prepares the run and executes a certain operation; a wrapper test then executes this performance test a ...

Utilities Servers: I've been thinking more about Nailgun, the server which hosts small Java programs to be run from the command line. One question is, why can't (or don't we) use Java more often for common utility tasks? Think of all the command line utilities written as executable (binary) or ...

Cool Swing/3D demo! Just checked out a Swing-based Java3D demo from Romain Guy's Weblog and it looks pretty cool. You see books as 3D images from Amazon, and see them rotate in real time to display the spline as well as the front cover. To run it, you'll need to ...

I was thinking about the MVC (Model-View-Architecture) design model while looking at an application with notifications. The application is mainly accessed through a complicated GUI client.

Working on my Website (Part II)
I started to work on this website again couple of weeks ago. Last year I'd written the content of my website in XML, and generated working XHTML with XSL. All of that was working, but there were problems, namely that I was terrified of changing ...

Writing and Markup
What I really want is just to writeup my website without worrying about markup, and to have full control when I finally present it. The website pages are written and stored as XML, before being converted to the XHTML that visitors see.The downside is the amount of typing ...

I was working with NetBeans the other day, debugging some of my
own code. I had been running the debugger repeatedly, tracing through
the code over and again. NetBeans gradually slowed down, and stepping
through lines of code became downright painful. I finally stopped and

Dynamic Language Integration in the JVM
I've been interested to see the different languages built on top of the JVM. If you do a web search for "jvm languages", you'll find a whole slew of them listed, some of which are still in active maintenance. One newish one, Groovy, has been ...
