onyinyang: 2023-06-15
Last week:
- finished lox-distributor tests
- reorganized more things within lox-rs (i.e., moving helper
files etc. into lox_utils, adding documentation, pipelines, etc.)
- tweaked the `gone` resources from rdsys, so that the
lox-distributor can handle them appropriately
This week:
- Looking into a more reasonable way of storing Lox library
data structures:
- https://gitlab.torproject.org/onyinyang/lox/-/issues/2
- https://gitlab.torproject.org/onyinyang/lox/-/issues/3
- First changing the vectors in the bridge_table to maps
with lookup by bridge fingerprint.
(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 useable 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?
Itchy Onion: 2023-06-08
Last week:
- fixed snowflake pipeline due to outdated Debian image
- continue working on rdsys#56 implementation. Still need to do the
following:
- finish up computing bridge distribution in Kraken
- does it have to be deterministic?
- does the disproportion have to be strictly followed
- finish writing tests
- refactor code because some functions are getting extremely long
- what to do with stencil package?
This week:
- review MRs
- continue working on rdsys#56 implementation. Still need to do the
following:
- fixed a problem with vanilla bridges not being added properly
to the database
- still working on tests
- adding a migaration patch
(https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/56#note_2908572)
hackerncoder: 2023-04-20
last week:
- (py-)ooni-exporter torsf (snowflake)
- (py-)ooni-exporter web_connectivity
Next week:
- work on "bridgetester"?
- how does Iran block bridges?
