onyinyang: 2023-06-29 Last week: - Finished changing vectors to maps - Started looking into db for Lox structures - Started working on Lox presentation for PETS This week: - fix up indexing of hashmaps for Lox bridgetable - Working on Lox presentation for PETS (to include some details about Tor integration) - Decide between databases to back the Lox structures (poloDB, redb, surrealdb seem like reasonable candidates) If time: - work on syncing Lox with rdsys given https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/168 - start thinking about metrics to add (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?

Itchy Onion: 2023-06-08 Last week: - fixed snowflake pipeline due to outdated Debian image - continue working on rdsys#56 implementation.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_290...)

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?
