Shelikhoo: 2024-01-16 Last Week: - [Pending] snowflake broker update/reinstall(cont.): https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf... - [Awaiting Review] Unreliable+unordered WebRTC data channel transport for Snowflake rev2 (cont.)( https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf... ) improvements - Merge request reviews - Automate bridgeline update for snowflake(https://gitlab.torproject.org/tpo/anti-censorship/connectivity-measurement/p... ) Next Week/TODO: - Merge request reviews - [Resume] Unreliable+unordered WebRTC data channel transport for Snowflake rev2 (cont.)( https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf... ) improvements
onyinyang: 2025-01-16 Last week(s): - Get conjure up and running (at least locally) - WIP Conjure stuff for Project 173 Next week: - Continue on getting conjure up and running (at least locally) - implement utls for conjure - start implementation of alternative registration methods As time allows: - Continue work on implementing issuer efficiency for check-blockage and trust-promotion protocols - Work on outstanding milestone issues: - key rotation automation
Later: pending decision on abandoning lox wasm in favour of some kind of FFI? https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43096): - add pref to handle timing for pubkey checks in Tor browser - add trusted invitation logic to tor browser integration: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42974 - 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!): - 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?
theodorsm: 2024-01-16 Last weeks:
Next weeks: - Fix merge conflicts in MR (https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf...). - Write instructions on how to configure covert-dtls with snowflake client - Condensing thesis into paper (on hold) Help with: - Test stability of covert-dtls in snowflake MR
