A few days back I upgraded my machine to the newest Ubuntu release. As is often the case with upgrades like this, there were a few issues. The main one is a conflict between my M2N4-SLI motherboard and the 2.6.17 kernel. I get the impression that Asus has left quite a few bugs in the… Read More: Ubuntu 6.10 (Edgy) upgrade »
Note: most of this is rambling, go to the bottom for the useful technical bit. I’m doing some work with large amounts of data (about 100 million rows), and today I tried loading it all into MySQL on my home machine, so that I could run some collaborative filtering tools over it easily. However, when… Read More: Trials of moving /var in Ubuntu »
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 »

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 »
