# `nederlandskie`

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`](https://crates.io/crates/sqlx) and [`scooby`](https://crates.io/crates/scooby)
- Language of posts is determined via [`lingua-rs`](https://crates.io/crates/lingua)
- Country of residence is inferred from profile information through ChatGPT via [`chat-gpt-lib-rs`](https://crates.io/crates/chat-gpt-lib-rs)
- Feed is served via [`axum`](https://crates.io/crates/axum)
