This one is good enough to blog twice. If you haven't seen it, check out the post on Metamorphic relations as test oracles. Fantastic paper - if you're into that sort of thing.
In addition to my blog here, I've recently started doing some contributing to the Software Quality Insights blog on IT Knowledge Exchange. The focus of my content on Software Quality Insights will be commentary on news and events related to software testing. I've added an RSS feed on the right to track my latest posts.
