City builder game. Includes save system tutorial in README.

C encoder/decoder for customs declaration formats. WCO Data Model XML, JSON, compact binary with CRC32 integrity.

POLER Quantum Weights (.poler/.pqw): zero-dependency Rust serialization - phase trits + sparse LENS topology + mmap zero-copy + McWeeny invariant P^2=P

An advanced, dependency-free decentralized clock synchronization and microsecond drift reconciliation engine written from scratch in pure C++17. Features hyper-compact packed data layouts (.zvn format), bare-metal single-dimension Kalman filters, and minimalist command prompt shells.

CLI archiver with Hamming error-correcting codes. Combines multiple files into one fault-tolerant archive with a custom binary format. C++17.

Simple movie database written in C for "Basics of programing (winter 2018)" course.

Open legacy Protel PCB board files in KiCad. Reads Autotrax, Easytrax, Advanced PCB, Protel for Windows, Protel PCB ASCII and .ddb design databases - no Protel, no Altium, no licence. Pure Python, zero dependencies.

Zero-allocation serialisation library for Go utilising in-place pointer resolution (SBC-IPR) and binary-search schema indexing (HIBI)

Go RAP binary codec for DayZ/Arma: decode/encode config.bin with rvcfg AST integration.

Java command-line tool that packs multiple files from a directory into a single archive and restores them — custom binary header format, stream-based I/O, incremental implementation.

A working Git implementation built from scratch in Java. Implements the real binary object store, DIRC index format, branching, three-way merge, and conflict detection. Compatible with the real Git.

C++20 market-data recorder with binary log format, deterministic replay, latency/throughput benchmarking, and replay-based scanners.

The LIPTK specification

A small browser-first binary container I built to package collection metadata and JPEGs into one deterministic, lazy-loadable file.

Open-source toolkit for lossless, reference-based reconstruction of large binary artifacts using deterministic CDC and compact SBD1 seeds.

Pure-Python Spine 4.1 .skel binary reader and writer, with a byte-identical round-trip. No dependencies.

Binary Format — independent third-party profile of a public API surface, by API Evangelist. Binary format refers to data encoding and serialization methods that use binary rather than text representations, including formats like Protocol Buffers, MessagePack, Avro, Thrift, CBOR, and others used in APIs and data storage systems for efficiency.

C89, single header, nostdlib raw geometry format

An efficient image archiving system with a GUI packer and a powerful, serverless web viewer.
