Show HN: A lightweight, stateless database for agent memory 4 by anuptalwalkar | 2 comments on Hacker News. I've been working on Polign and built a small prototype around something I've been thinking about with agent memory. I have built a lightweight/stateless vector db + BM25 search which works really well with typed facts and structured queries. It uses your own S3, or GCS bucket as primary storage, and restarting a node is fairly quick.

Show HN: PicoMQ – Durable Streams over HTTP, on object storage 15 by adesh_nalpet | 0 comments on Hacker News. PicoMQ is a Rust server for Durable Streams, built on Object Store. Cheap, URL-addressable, granular streams (create/append/read/long-poll/SSE), with Pico Protocol or Durable Streams Protocol as the facade. S3Stream is the stream storage primitive, used in AutoMQ, shipped as a Rust library. Coordination is a command log in Postgres.
