Aleksei Voronov 419f72f3bb Store Bluesky firehose host as part of subscription state 
The host has changed recently and the cursors are, apparently, incompatible with each
other, so we need to migrate to the new one, and this seems like the easiest way to
do it:

1. Store the host as part of the subscription state
2. Roll out the version that uses that new column as part of all queries
3. Switch to the new host
4. Roll out the version with the new host
   - The new instance will start processing messages with a 0 cursor and so start anew
   - The old instance will die off

A Bluesky feed generator written in Rust.

The specific algorithm indexes and serves posts written in Russian language, by people living in Netherlands.

  • Posts are stored in PostgreSQL via sqlx and scooby
  • Language of posts is determined via lingua-rs
  • Country of residence is inferred from profile information through ChatGPT via chat-gpt-lib-rs
  • Feed is served via axum

Deployed in production at https://nederlandskie.plansfortheday.org/

Published on Bluesky at https://bsky.app/profile/did:plc:376mcc6k4s5p7qbtyjrgph5k/feed/nederlandskie.

Setup

  1. Set up a PostgreSQL database

  2. Create tables using SQL provided in [sql/01_create_tables.sql].

  3. Copy .env.example into .env and set up the environment variables within:

    • PUBLISHER_BLUESKY_HANDLE to your Bluesky handle
    • PUBLISHER_BLUESKY_PASSWORD to Bluesky app password that you created in settings
    • CHAT_GPT_API_KEY for your ChatGPT key
    • DATABASE_URL for PostgreSQL credentials
    • FEED_GENERATOR_HOSTNAME to the hostname of where you intend to host the feed

  4. Determine your own DID and put it in PUBLISHER_DID env variable in .env:

    cargo run --bin who_am_i

Running

Populate and serve the feed

cargo run

The feed will be available at http://localhost:3030/.

Determine your own did for publishing

cargo run --bin who_am_i

Publish the feed

cargo run --bin publish_feed -- --help

Force a profile to be in a certain country

cargo run --bin force_profile_country -- --help
