onyinyang: 2023-02-29
Last week(s):
- continued prep for HACS/DRL meeting
- Thought about/work on other Lox test deployment milestone pieces
-Lox Ready for Open Testing Call · Milestones · The Tor Project / Anti-censorship / lox · GitLab
- worked on better invitation encoding issue: Better Invitation Encoding (#58) · Issues · The Tor Project / Anti-censorship / lox · GitLab, implemented base64 serialization/deserialization but waiting for more feedback from the wider team
- looked into bridge blockage reporting: Create a detailed workflow for investigating and responding to blocked Lox bridges (#57) · Issues · The Tor Project / Anti-censorship / lox · GitLab
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!): Riseup Pad
- 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
