Anti-censorship work meeting pad

Next meeting: Thursday September 12th 17:00 UTC

Weekly meetings, every Thursday at 17:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress).

== Goal of this meeting ==

Weekly checkin about the status of anti-censorship work at Tor.
Coordinate collaboration between people/teams on anti-censorship at Tor.

== Links to Useful documents ==

    * Our anti-censorship roadmap: https://dip.torproject.org/torproject/anti-censorship/roadmap/boards
        * Our roadmap consists of a subset of trac tickets.
    * The anti-censorship team's wiki page: https://trac.torproject.org/projects/tor/wiki/org/teams/AntiCensorshipTeam
    * GetTor's roadmap: https://dip.torproject.org/torproject/anti-censorship/gettor/boards

    * Tickets that need reviews: https://trac.torproject.org/projects/tor/query?status=needs_review&component=%5eCircumvention&col=id&col=summary&col=component&col=owner&col=type&col=priority&col=milestone&col=reviewer&order=priority

--- 12th September 2019 ---

== Announcements ==


== Discussion ==

    * Any services left that aren't monitored or restarted on crash/reboot?
        * Set up systemd user script for GetTor (based on <https://help.torproject.org/tsa/doc/services/>)

== Actions ==


== Interesting links ==

    * https://google.github.io/eng-practices/review/reviewer/
        * Google's guide on how to do code reviews. Worth a skim. My personal take-aways:
            * Make sure that patches improve the health of the existing code. They won't be perfect.
            * "One business day is the maximum time it should take to respond to a code review request (i.e. first thing the next morning)"
                * However, never interrupt your focused work to do a code review.

== Updates ==
