* Past meeting notes can be found at:
* https://lists.torproject.org/pipermail/tor-project/
* Tickets that need reviews: from sponsors, we are working on:

== Announcements ==
== Discussion ==
* merge requests in the snowflake webextension might stay months without review
* https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake-webext/-/merge_requests
* should we add it to triage bot? who should be in the pool of reviewers?
* yes, meskio will configure triagebot to auto asign reviews to: cohosh, shelikhoo and meskio
* Update on Analysis of speed deficiency of Snowflake in China, 2023 Q1 https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40251#note_2883879
* after a lot of research the proposed solution is to enable datagram transport on webrtc to deal with the packet loss situation
* that will convert webrtc into an unreliable channel, and snowflake will add reliablity with kcp
== Actions ==
== Interesting links ==
*
== Reading group ==
* We will discuss "" on
* Questions to ask and goals to have:
* What aspects of the paper are questionable?

onyinyang: 2023-03-30
Last week:
- Finished up the handling of changed resources in the Lox library
- Added some wiki documentation to Lox overview repo: https://gitlab.torproject.org/tpo/anti-censorship/lox/lox-overview/-/wikis/home
- Tried testing changed/gone resources in rdsys (mostly familiarizing myself with rdsys code)
- Considered how to sync Lox bridgetable for each rdsys update of new bridges
This week:
- Figure out how to test changed/gone resources and ensure the rdsys backend api is behaving as expected for handling updates from rdsys
- Start implementing a function in lox distributor/lox library to handle syncing of Lox bridgetable
Needs help with:
- Expected behaviour of rdsys on update of bridges: e.g., where all changes to bridge descriptors are recorded (i.e., networkstatus-bridges, bridge-descriptors, cached-extrainfo files), which of these trigger updates from rdsys,and how _should_ the distributor be responding (if it's working as expected)

This week:
- Tested and created a potential broker security issue (#40266)
- Stil working on #40231 -- validate SDP contains candidate at the "/client" and "/answer" endpoints broke almsot all of the unit tests
