Okay, to be technical, we get the raw values for each metric: say the number of job ad that mention language X, or the number of Google search results. Then, using R/R Studio, we normalize the the raw values so they range from 0 to 100, with 100 fixed as the highest valued language in each group. Then the metrics are summed, using different weights for the Spectrum default, Jobs, and Trending. The results are normalized again to produce the 3 rankings. In previous years all this weighting and combining was done client-side, so you could try your own weights if you didn't like ours, but for the reasons I give the article we dropped this feature in favor of precomputed results this time out.
