...Fountain coding makes the stream tolerant of missed, blurred, duplicated, and out-of-order frames without requesting retransmission. Each QR frame includes session and file metadata, allowing a receiver to join an active stream or reset when a new session begins. QR decoding runs through zxing-cpp compiled to WebAssembly and uses workers to process camera frames efficiently. Configurable settings control payload size, transmission speed, QR density, capture resolution, and worker count, while a final hash verifies the recovered file.

Runtime type system for IO decoding/encoding

io-ts is a TypeScript runtime type system for decoding, validating, and encoding data at application boundaries. It solves a common TypeScript limitation: static types disappear at runtime, but external inputs still need to be checked safely. The library lets developers define codecs that represent both runtime validation logic and static TypeScript types. This approach is especially useful for APIs, configuration files, JSON payloads, database results, and any data that enters a program from an unknown source. io-ts integrates closely with functional programming patterns and the fp-ts ecosystem. ...

WhoDB is a lightweight audit logging extension for PostgreSQL that helps track who accessed what data and when. It uses logical decoding and hooks into PostgreSQL internals to log query metadata, user identities, and timestamps in a separate audit schema. WhoDB is useful for compliance, security monitoring, and debugging in multi-user environments.

cloudflare-worker-jwt is a JavaScript library for handling JSON Web Tokens (JWTs) inside Cloudflare Workers. It enables authentication, token validation, and signature verification for serverless applications.

BSON parser is the core JavaScript implementation of BSON (Binary JSON), the data format used by MongoDB to represent documents on the wire and in storage. It provides encoding and decoding capabilities so JavaScript environments like Node.js and browsers can serialize rich data structures (including types not native to JSON) into the compact, efficient BSON binary representation used by MongoDB drivers and servers. Value types such as ObjectId, Binary, UTC datetime, Decimal128, and Long are provided as first-class objects, enabling precise representation of data that would otherwise be lossy or awkward in plain JSON. js-bson is designed for performance, with optimized algorithms for reading and writing binary data, minimizing overhead in database operations. ...

Skylight is an open-source project that turns a ceiling into a real-time visual map of aircraft passing overhead. It decodes ADS-B signals from an RTL-SDR radio or can use a web API for testing without radio hardware. The system renders planes onto a ceiling-pointed projector so nearby aircraft appear to move across the room as they move through the sky. It also adds a live sky layer with the sun, moon, stars, constellations, planets, satellites, and the ISS based on the user’s location and...

...All libraries are bound together by the core Common library keeping track of chain specifics and hardfork changes. They are complemented by helper packages like RLP for data encoding/decoding or Util, providing helper functionalities like (byte) conversion, signatures, types and others. Finally, the EthereumJS Execution Client (EthereumJS) has been in active development for some time now. It already serves a variety of purposes like testing, research (e.g. EIPs) and developer tooling.
