onyinyang: 2023-08-24
Last week(s):
- Vacation!
- Finalized db implementation in sled
- Working on a different approach for getting resources from rdsys since Lox requires knowledge of bridge state over time: Add Functionality needed to appropriately handle resources from rdsys (#8) · Issues · The Tor Project / Anti-censorship / lox-rs · GitLab
This week:
- Continue with refactoring of rdsys_backend_api and integration with lox-distributor
- Work on adding metrics
(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?
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- fixed snowflake pipeline due to outdated Debian image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 (Consider persistent storage of bridge information (#56) · Issues · The Tor Project / Anti-censorship / rdsys · GitLab)
