Hey,

This is the 15th weekly update from revision scoring team that we have sent
to this mailing list.

*New developments:*

   - We'll no longer unnecessarily load the models into memory on the web
   workers[1].


   - We can now score multiple models against the same revision ID for
   (essentially) free[2].


   - Our precaching system will take advantage of this to drop load by
   about 3X[3].


   - Update wmflabs deploy repo for new version of ORES[4].


*Documentation & maintenance:*

   - We completed deployment and maintenance docs for Wiki labels[5], which
   means we've now got complete docs for our systems[6].


   - We implemented basic continuous integration tests for the ORES
   extension[7].


*Downtime:*

   - We had a 1 hour long downtime while trying to deploy new code to
   ores.wikimedia.org[8].  We've filed two critical tasks for making sure
   we don't make the mistake again[9,10].


1. https://phabricator.wikimedia.org/T134606 - Score multiple models with
the same cached dependencies
2. https://phabricator.wikimedia.org/T139407 - Don't load models into
memory of web workers
3. https://phabricator.wikimedia.org/T141376 - Update precached to group
requests by model
4. https://phabricator.wikimedia.org/T141377 - Update wmflabs deploy repo
for new version of ORES
5. https://phabricator.wikimedia.org/T131768 - Wikilabels deployment docs
6. https://phabricator.wikimedia.org/T106271 - Document maintenance tasks
7. https://phabricator.wikimedia.org/T140455 - CI test for ORES extension
8. https://wikitech.wikimedia.org/wiki/Incident_documentation/20160801-ORES
9. https://phabricator.wikimedia.org/T141823 - Set up password on ORES Beta
redis server
10. https://phabricator.wikimedia.org/T141825 - Config beta ORES extension
to use the beta ORES service

Sincerely,
Aaron from the Revision Scoring team
