onyinyang: 2023-06-20     Last week(s):         - MSR talk         - Working toward building tor-browser with lox-wasm binary to help out with             integration work as needed: ran into many issues trying to do this with Fedora     Next week:         - Global Gathering Application         - Fix Key Rotation MR for hyper v1         - Working toward building tor-browser with lox-wasm binary to help out with             integration work as needed: resolve build issues on Fedora         - Work on outstanding milestone issues: https://gitlab.torproject.org/tpo/anti-censorship/lox/-/milestones/1#tab-iss...             - prepare for end to end testing of the Lox system with browser integration         Later:         - begin implementing some preliminary user feedback mechanism to identify bridge blocking based on Vecna's work         - improve metrics collection/think about how to show Lox is working/valuable         - sketch out Lox blog post/usage notes for forum

(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?
