I have recently begun developing using TDD/BDD and am also learning more about Agile development practices.
I'm actively involved in the local tech community and help organise the local monthly TechMeetup, where I recently gave a talk on BDD.
I try to pass on the knowledge I've gained when possible. I recently helped a friend's daughter develop a standards-compliant website using XHTML and CSS for her Duke of Edinburgh award. This summer I have been assisting four teams of MSc students at Aberdeen University with out-of-hours Rails support on their projects.
