Thanks for taking part in this series. The goal is provide brief, but informative overviews of technologies and practices people are using in IT. That is, "what's in your stack." There are 4 questions below, and the end result (published at
http://RedMonk.com/cote) will narrow down on one of the answers with a follow-up question (and answer) from me.
The goal is to provide people with a peek at what technologies, hardware, frameworks, practices, and such others are using for their development. This isn't intended to be a discussion of business models, products, or other things like that except as a way to inform how various technologies and practices are a good, or poor, fit for those "business" goals: just a discussion of technologies used.
