I have started using react.js + flux and I really like them. But I wanted to check what is your stand about the patents clause. Are you using it for your startup or are you steering clear? Also if you are a consultant/freelancer, are you using it for your client's project?

I fall in the second category and I am not sure what should be the things that I need to consider before I start using it for my client's work?

I have a reasonable understanding of relational databases. I am not so sure about NoSQL databases. Though I have used mongodb in the past. Can someone point me to resources to get a deeper understanding? How do I go about learning the trade-offs of choosing say a document store over a key value store. Also CAP theorem and related trade-offs. When is NoSQL better suited than relational etc.
