== Discussion ==
- Snowflake debian package is outdated:
- Is there a plan for updates? If AC-Team wants to increase the
number of snowflake standalone proxies, we need to maintain deb
packages. Should we start a call for maintainers? If so, what are the
requirements?
- MR:
https://gitlab.torproject.org/tpo/web/community/-/merge_requests/386/diffs
Please note that every new string added to the community portal is
localized. If this is a temporary issue, I don't think it worth merging
it. (gus)
- we do plan to update it but it will take some months, there will
be work as part of P146
* https://github.com/eyedeekay/blizzard/ "Blizzard: The I2P
Snowflake donor Plugin"
* should we ask them to use a diferent identifier than
"standalone" to find them in the stats?
* meskio will open an issue on their side to ask them to use a
different name
* https://github.com/eyedeekay/blizzard/issues/5
* meskio has archived
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake-mobile
* hasn't being updated in 3 years
* no complains for now
* PT binary size updates
*
https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42607
* Remove conjure from android as a last resort
* Manifest V3 Deployment pending, will proceed on next week
== Actions ==
== Interesting links ==
== Reading group ==
* We will discuss "Bridging Barriers: A Survey of Challenges and
Priorities in the Censorship Circumvention Landscape" on Aug 22, 2024
* PDF at
https://www.usenix.org/conference/usenixsecurity24/presentation/xue-bridging
* 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?

Last week(s):
- continue with key rotation integration work
Next week:
- continue with key rotation integration work
- collect issues and TODOs for all Lox work that needs to be
done before deployment
- add trusted invitation logic to tor browser integration:
https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42974
- Work on outstanding milestone issues:
in particular:
https://gitlab.torproject.org/tpo/anti-censorship/lox/-/issues/69
- key rotation automation
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?
