onyinyang: 2023-11-30
Last week(s):
- Finished up remaining docs tasks for crates.io publishing
-published all relevant Lox crates to crates.io
- SOTO anti-censorship team presentation preparation
- looked into Telegram bot
- attempted hyper upgrade, many breaking changes so this will take some work

     \- continue Telegram bot dev
     \- attempt hyper upgrade again
     \- Splintercon

(long term things were discussed at the meeting!): Riseup Pad
- 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?
