fountain-codes

Optimized implementation for color-icon-matrix barcodes

Ultra-fast offline file and text transfer over animated QR codes with WASM fast_qr, ZXing and RaptorQ.

atp — fountain-coded file transfer (RaptorQ over UDP/QUIC) that outruns tuned rsync on real networks. Verified end-to-end, fail-closed.

fast compact rateless codec

Blazing Fast Erasure-Coding with Random Linear Network Coding (RLNC)

A free and open implementation of Raptor codes

Multiplexed, coroutine-powered reliable UDP for Kotlin using fountain codes

Fountain codes implemented in Rust

Interactive visual deep-dive into RaptorQ (RFC 6330) fountain codes — 5 hands-on visualizations, Python demos, and a first-principles walkthrough of the protocol that turns files into mathematical liquid

Maintained fork of bashalarmistalt/decimen-optical-transfer with arbitrary file transfer, PWA support, and image optimization.

Move files between devices with a screen and a camera — offline optical transfer of RVF cognitive containers and WASM artifacts over animated QR codes. Mobile-first, no network, no accounts, SHA-256 verified.

Narrated, 3Blue1Brown-style 4K math explainer videos built in Rust with franken_manim (native TeX, no LaTeX, no Python) and voiced by FrankenTTS. Every number computed and oracle-checked, every line ASR-verified and never time-stretched, every frame looked at, with a warm procedural score under the voice.

experimental data transceiver using QR codes

C++20 research system for adaptive FEC, cross-layer control, and resilient heterogeneous networking under energy and link constraints.

ATAK plugin for MeshCore LoRa mesh radios — off-grid position, chat and CoT with no TAK server, no cell service, and no amateur licence. GPL-3.0, with a normative wire spec and golden test vectors.

A highly configurable peer-to-peer FRC scouting web app.

Air-gapped file transfer by light: one screen strobes a file as QR frames, a camera rebuilds it — RaptorQ fountain, CRC-gated, BLAKE3-verified. No network, no pairing, no server.

Implementation of "Progressive decoding of DNA-stored JPEG data with on-the-fly error correction"

Send a file straight from one device to another. A QR code carries the key; the file goes over WebRTC; nothing in between ever holds a readable copy.

Air-gapped file transfer over screen and camera — LT fountain codes + animated QR. Pure TS core + React Native bindings.
