 * Discussions Trey completed the analysis for optimizing language identification for the Dutch Wikipedia (nlwiki). The results were good (F0.5 = 82.3%) but not great. The small proportions of queries in the Romance languages and in German led to many more false positives than true positives and so they had to be excluded. Future work on improving confidence may help.
 * We could use help translating (via translatewiki) the relevant "showing results from" messages into Dutch. We'll need English, Chinese, Arabic, Korean, Greek, Hebrew, Japanese, and Russian translations.
 * Analysis team had a discussion on how to use better wording for phrases like "users were 1.07 times more likely to do X" and decided on using phrases similar to "we can expect 2-9 more sessions to click on a search result when they have the new feature"
 * Search team wrapped up researching the ElasticSearch instabilities on the eqiad search cluster on Aug 6, 2016; nothing conclusive was found.
 * Interactive:
 * &lt;maplink> has been enabled on all wikis (announced via email to wikitech-l)
 * Geoshapes data service is now integrated into all maps info
 * Search:
 * turned off BM25 A/B test, awaiting analysis
 * pushed into production a change that implemented ascii-folding for French
 * Improved balance of nodes across rows for ElasticSearch eqiad cluster
 * Portal:
 * Currently blocked on this check-in to gerrit
 * Our elasticsearch clusters now have "row aware shard allocation". This means that we can theoretically lose one row of servers in our datacenter and still serve search traffic.

 * Did you know? A study came out yesterday showing that giraffes are actually four distinct species, rather than one. (Original article and BBC report.) Of course, the English and German Wikipedia pages on giraffes have already been updated!
