\* https://github.com/theodorsm/covert-dtls
\* trouble integrating it into snowflake \- dependency/version issues
\* breaking changes with the version of pion/stun used in snowflake
\* but snowflake is already using the latest pion/stun?
\* theodorsm forked the older version of pion/dtls used by snowflake and re\-applied the covert\-dtls changes
\* snowflake is using pion/dtls v2\.2\.7 while latest is v2\.2\.11, but unreleased code is needed \(should come with v2\.2\.12\)
\* as specified by current pion/webrtc v3\.2\.42 https://github.com/pion/webrtc/blob/v3.2.42/go.mod#L7

* Questions to ask and goals to have:
* What aspects of the paper are questionable?
* Are there immediate actions we can take based on this work?
* Are there long-term actions we can take based on this work?
* Is there future work that we want to call out in hopes that others will pick it up?

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: Lox Ready for Open Testing Call · Milestones · The Tor Project / Anti-censorship / lox · GitLab
- 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?
