Added Haskell and Lua programming languages to the Ranking Overview.
Closed questions (and their related answers and votes) will not be taken into account from now. Less than 5% of StackOverflow questions are closed (due to bad practices) so it doesn't make a crucial impact, but keeps the charts more accurate.

StackOverkill Help - Frequently Asked Questions
What are those charts?
These charts represent the "popularity coefficient" of the different programming languages and technologies (frameworks, libraries, software...) based on StackOverflow's activity (tags, questions, answers & votes).
What is the grey region at the end of every chart?
The grey region represents the trending prediction for languages and technologies. This prediction is based on a polynomial regression algorithm. The rest of the data reflects the real activity.
Why is the current month within the prediction region?
These charts are calculated from the public StackOverflow's dataset, which is released every 3-4 months (read more in the About section). This website's data cannot be updated until the next dataset is released.
