onyinyang: 2023-03-07
Last week(s):
- continued prep for HACS/DRL meeting
- finished base64 invitation encoding
This week:
- continue prep for HACS/DRL meeting
- improve metrics collection/think about how to show Lox is
working/valuable
- sketch out Lox blog post/usage notes for forum
- attempt hyper upgrade again
(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?

Last weeks:
- Currently in the start phase of writing my master thesis
(to be finished late june 2024) in communication technology on reducing
distinguishability of DTLS. The goal is to implement a validated DTLS
anti-fingerprinting library similar to uTLS (useful for Snowflake).
Next weeks:
- Talk with Sean DuBois about contributing to adding
anti-fingerprinting capabilities to the pion library
Help with:
- Find recent data set of captured DTLS traffic
