I look for authentic problems that are worth studying and ultimately solving.
I've written my own open source tools:

I pontificate regularly and engage with my community of fellow testers and developers:
• http://testerstories.com
I've published papers and poems and stuff:

I'm a generalist when it comes to programming languages and I'm happy to test any application, written in any language. My true love is the dynamic language and, when writing test solutions, Ruby makes me the happiest with JavaScript becoming a close second.
