  This week (2020-10-29):

    Reviewed Snowflake patches, rdsys patch, grant budget, and S30 report.

    Lots of rdsys and Salmon refactoring.

    Made good progress on cohosh's idea of making Salmon more privacy
preserving by not storing a social graph on the server side.

    Experimented with statsd/graphite for metrics.

    Seems very promising.

    Took a look at the recent censorship in Tanzania.

  Next week:

    Finish refactoring Salmon and start working on cohosh's "social
graph reduction" idea.
