onyinyang: 2023-11-09
         Last week(s):
             - Continued work on Lox telegram bot
             - Hackweek: Docs for Lox https://gitlab.torproject.org/tpo/community/hackweek/-/issues/20
         This week:
             - Hackweek: Docs for Lox https://gitlab.torproject.org/tpo/community/hackweek/-/issues/20
             - Publish Lox crates to crates.io

(long term things were discussed at the meeting!): https://pad.riseup.net/p/tor-ac-community-azaleas-room-keep
                         - brainstorming grouping strategies for Lox
buckets (of bridges) and gathering context on how types of bridges are
distributed/use in practice
                         Question: What makes a bridge usable for a
given user, and how can we encode that to best ensure we're getting the
most appropriate resources to people?
                                 1. Are there some obvious grouping
strategies that we can already consider?
                                  e.g., by PT, by bandwidth (lower
bandwidth bridges sacrificed to open-invitation buckets?), by locale (to
be matched with a requesting user's geoip or something?)
                                 2. Does it make sense to group 3
bridges/bucket, so trusted users have access to 3 bridges (and untrusted
users have access to 1)? More? Less?
