== Discussion ==
* Snowflake Enable Distributed Snowflake Support at broker src shell
*
https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/95
* old proxies were rejected starting monday of this week
* everything seems smooth, we saw a drop in polls as expected,
but we still seem to be mostly in capacity and it looks worth it to move
forward.
* plan to make a community announcement about the rejection of
old proxies
* Iran:
* Anything (resources, work, support) that may be needed to
help circumvent censorship in Iran right now?
* There are multiple reports of snowflake not working in Iran
in some ISPs, but so far we didn't receive a more detailed report.
* Should we try out new PTs? dnstt, etc?
* Get snowflake in Tor Browser updated to support utls
* meskio will explore if orbot has support for uTLS in
snowflake or if that could be added to be able to see if uTLS solves the
problem of snowflaked
* telegram download bot
* apart from a minor issue that needed a one-line fix, launch
went well
* external contributors have also participated
* heavy focus on building new features (especially android
builds without downloads.json), which in turn either requires a lot of
refactoring
* lots of issues concerning third-party libraries again, most
bug reports/feature requests have been made to upstream developers
* logging has been replaced with aiologger to protect the
bot from "hugs of death"
* aiologger does not show dates in files. hacky solution:
obtain the date when methods of the logger are called, maintainers are
not very active
* we depend on undocumented behavior. After doing research,
it seems OK here
* are new versions with regressions OK?
* translations
* a recent change in how exceptions are communicated to the
user has pushed the readiness of translations back
* will be expanded once development (mostly) stagnates
* existing translations will not be touched until that happens
* comments are still a TODO
* new experimental gettor backend
* authored in go, could potentially be merged together with rdsys
* makes sharing large files through platforms with download
limits under 100 MB (unless if you pay, or not) possible (by splitting
them and providing the users with an app to put it back together)
* relies on commands like the other gettor implementations
* uses mongodb as a backend
* android versions work too
* currently private
* built-in bridgdes vs 'settings' pool: do we need more built-in
obfs4 bridges?
-------NEW TOPIC BELOW-----------
* Release a new version of snowflake webext proxy src shell
* loss of bandwidth at snowflake-01 bridge
* dynamics are the same as at the time of 2022-10-06 meeting
* the cause of the loss of bridge bandwidth is still unknown
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40207
https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/96#note_2840481
* shelikhoo will do a temporary reversion of the broker
deployment of 2022-10-03 that rejected old proxies
(https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40193)
on 2022-10-17, just as a test
* even though the deployment of 2022-10-03 does not quite
match up in time with the bandwidth drop
== Actions ==
== Interesting links ==
*
https://www.digitalrights.community/blog/tools-resources-actions-to-support-irans-feminist-uprising
== Reading group ==
* We will discuss "" on
*
* 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?

Itchy Onion: 2022-10-13
Last week:
- testing two more RACE snowflake plugin fixes (using
io.Copy() to send message and connection pool)
This week:
- bump snowflake plugin to version 2.3.2
- trying to trace where the message dropping happens in the
snowflake library used by RACE. (I've been back and forth on this one,
but now I believe message dropping and unclosed TCP sockets are not the
same issue. The CI tests that are failing doesn't send that many
messages for a system resource issue to kick in. I've traced the message
in the plugin code, and see they are all sent to the snowflake library
code without dropping. So maybe an issue with the version of snowflake
lib that's used in RACE)
