Ruby's share drops on github, Perl's stays
Java moves to 3rd position to replace Python which is now in the 4th. Perl's place stays the same at the 9th, as well as its share at 4%. Ruby's share drops pretty significantly from 14% to 12%. More precise numbers are not provided.
I guess this is just a normalization process as Ruby projects were the early adopters at github. Kind of reminds me about the current normalization process where other languages replace Perl for web applications, because Perl used to dominate and was the early language during the pre-dotcom-boom/bust era.
