http://korma.wmflabs.org/browser/who_contributes_code.html contains information outdated, including
- "People 2013 Q4" table
- "How is the weight of the WMF evolving?" graph ending in August 2014
- "The evolution of the total amount of merged commits" graph ending in February 2015
There is no way to tell whether the other metrics are updated, but seeing their neighbors it is impossible to trust them either.
