Notable Action items[edit]


Amir Ahroni

  • Working on the new main page for
  • Working on stats for Google on translations in Wikimedia and In contact with Dan for that. Will need to run some scripts on the cluster.
  • Translate is running into multiple higher severity issues that are caused by master/slave setups in Wikimedia and the inherent replication lag it sometimes suffers form, however small. There is no development environment where this can be tested. How can we get such an environment, so that we can fix the open issues, and in the future possibly even create tests that count on the replication lag? IMO the ideal situation would be that beta labs always has at least one second of replication lag, and that there's a puppet package that allows setting up a master/slave lagged environment in labs.
    Faidon suggests to get in contact with Ops.
