== Callouts == * Releng: Trebuchet's days are numbered. If you care about these projects please get in touch with #RelEng ** These are the last remaining trebuchet projects: *** iegreview *** scholarships *** ocg *** dropwizard * Wikidata: * For weeks we see thousands of hard to track user-facing Lua errors, see https://phabricator.wikimedia.org/T170039. We believe https://phabricator.wikimedia.org/T171166 might fix it, but need help by devs willing to touch LuaSandbox build.

=== Readers === ==== Web ==== * Completing roll out of Page previews to all projects but enwiki and dewiki (likely to be stalled until post Wikimania) * RelatedArticles now renders articles in footer rather than side bar. ( https://phabricator.wikimedia.org/T165991)

==== Reading Infrastructure ==== * Blocked by: * Blocking: * Updates: ** MCS gets geo coordinates from action API instead of Parsoid. ** Got rid of action=mobilview API calls for regular pages.

=== Reading Discovery ==== * Updates ** Working on search thumbnail AB test https://phabricator.wikimedia.org/T149811

=== Contributors === ==== Collaboration ==== * Most of our team was at Wikimania. * However, we continued work on RC Filters and Echo * Echo: Merged a "Mark all as read" patch from community member and worked on additional patches (e.g. edit-user notification) * RCFilters: Small fixes * Flow: In-progress work on a feature to allow you to add inline Flow discussion linked to specific text.

== Technology ==

=== Analytics === *2 team members in wikimania, 2 on family leave, 1 of our team members coming back next week from parental leave. Not a lot happened. *We figured out issue with timeouts in varnishkafka, there was one host running too new of a version of kafka API *Still working on purging eventlogging data, moving to cluster some data out of MySQL (will make DBAs happy). Couple tables that are about 0.5 tb. *Ordering new hosts to replace eventlogging MYSQL hosts using some budget we will not need for the new Kafka cluster. *Edit History Reconstruction, made a snapshoot custom for Neil (editing data analysts) to calculate metrics on. *Wikimetrics had stop working due to some recent changes to labs db connection limits, fixed that.

=== Services === * Blockers: none * Updates: ** Wiped out Parsoid HTML cache in preparation for Cassandra 3 upgrade *** Elevated VE latencies for a while while new storage is populated

=== Technical Operations === * '''Blocked''': ** by noone * '''Blocking''': ** none * '''Updates''': ** Wikimania + Debconf week, not much happened.

=== Community Tech === *Updates: CodeMirror and LoginNotify are still coming!

=== Fundraising Tech === * looking into db replication lag - it'll get up to like 5000 sec behind, but restarting mysql on the replicated copy will make it catch up in less than a minute * continuing new API work with main credit card processor * updating our interrupted-donation-resolver to work generically so we can use it for PayPal express checkout * refinements to CiviCRM<->bulk mailer data flows * CentralNotice clone campaign feature almost ready for CR

=== Scoring platform === *Blocked **Feeling the pain of no git-fat in labs deployments (our git repos are huge!) ***https://phabricator.wikimedia.org/T171758 ***Releng, can this be prioritized? *Updates **New ORES model information available at https://ores-misc.wmflabs.org. Demo coming soon. ***Mostly an FYI for Collab Team
