This is an open-source experiment in how far we can reconstruct a real environment using only public geospatial data, rendered entirely in the browser.

No GIS software, no install.

Everything increasingly runs on Ed25519 keypairs, but Ed25519 public keys can be encoded as text in dozens of surface-incompatible different ways: hexadecimal, Base64 (OpenSSH), Base32z (iroh, pkdns), Base58 (NEAR), and Multibase (IPFS, libp2p), just for starters.

Edky is a command-line tool and Rust library that converts between these Ed25519 surface encodings, aiding use of the same underlying keypair across e.g. an iroh endpoint, a libp2p peer, or a NEAR Protocol account. (Surprisingly, a conversion utility like this didn't yet exist!)

Hi, inspired by Andrej Karpathy's autoresearch, I built autoretrieval, a small framework that lets an AI agent improve a RAG pipeline by running experiments against an evaluation dataset.

The agent edits the retrieval pipeline, runs an eval, checks whether the F-beta score improved, keeps or discards the change, and repeats. It can try different chunking strategies, chunk sizes, the number of retrieved chunks, embedding models, keyword retrieval, and more, while keeping a log of every experiment.

The repo also includes a script that generates question and reference-highlight pairs from any document collection. This makes it possible to optimize a RAG pipeline for domain-specific data.

On one of my own RAG pipelines, it more than doubled the F3 score after a few hours of running experiments.

I'd love to hear any feedback or ideas.
