This as with many of my other posts, was inspired by my Software Carpentry instructor training. Nearly, three years later and so much of what I learned still rattles around my brain and often out my mouth.
To start with, many thanks to all the people who posted encouraging comments on my first post. I really appreciate all the support and shared experiences.
