This article is based on IEEE Spectrum’s 2014 ranking. I agree with the way the ranking is done. Most of the time this language popularity ranking skewed based on the ranking provider. This time IEEE spectrum has considered 10 sources and they are the happening places with respect to language and technology. Some of them are Google Search, Google Trends, Twitter, GitHub, Stack Overflow, etc.
