I’ve just put out an 0.20 release of eMusic/J. This fixes an issue that appears only on some JVMs (in this case, it seems to be Blackdown) where System.getenv(String) isn’t supported. However, it doesn’t fail gracefully, no…it throws an Error (not just an Exception even). See these Sun bug reports for details. I think that… Read More: eMusic/J 0.20 – fix for a weird Sun decision »
I’m writing this post from my new computer, finally an upgrade from my venerable old Duron 700.

After several months of not getting around to it, I’ve finally put out a new version of eMusic/J. There aren’t a huge number of changes in this one, but there is one that will be significant for new users: it no longer requires Sun Java, any 1.4 Java environment will do the job. Thanks to… Read More: eMusic/J 0.19 released – now with less mess! »
If you want to link to an html file directly in a subversion repository, there is a problem. By default, subversion doesn’t distinguish between filetypes other than binary versus text. So when you request a (text) file directly from the repository, it comes in as text/plain, no matter what it really is. This causes all… Read More: Setting the Content-Type on a subversion file »
Here is a great explanation of when using proprietary, or at least close-format-based, software can be life-threatening. Quite a scary idea.
I was playing with a test server for something I was working on, and one of the data files got corrupted. From the look of it, half way through one write process, another started, erased the file, wrote the new content, finished. Then the first one wrote the remainder of the data. This confused me… Read More: Java file-locking issues on Linux (Ubuntu Dapper)? »
I was asked to install Ubuntu Linux on someone’s Acer Travelmate 230 laptop, and I ran into a problem that was very easily fixed, once I knew what it was. However it wasn’t documented anywhere under the laptop model, which made finding the solution hard. The problem was that X would start with only a… Read More: Installing Ubuntu on a Travelmate 230: X Issues »
If you’re packaging a set of data into a class to pass to the client side of Google’s web toolkit, there are two things you must do for it to work. One is implement IsSerializable, the other is provide a no-args constructor.
Recently I’ve been using the Google Web Toolkit (GWT) for writing a web-based application (nothing I can talk about just yet 🙂 ). It’s a very nice way of building an AJAX-type web app in pure Java. You write the client-side code in much the same way as you would a typical Java GUI application,… Read More: Google Web Toolkit »
I went for a walk today, and found a couple of interesting looking aliens. The first being a small-person-sized (and unusually dark) “grey” [click for larger images]: The other clearly demonstrates why they have arrived: they want to strip the Earth of its resources! .
