Yazi is a high-performance terminal file manager written in Rust, utilizing non-blocking async I/O for efficient file management.

ChaosSQL is a deterministic concurrency and isolation fuzzer for PostgreSQL, MySQL and SQLite. It schedules concurrent transactions, detects invariant violations such as lost updates and write skew, shrinks failures to minimal reproductions, and can guard CI pipelines against regressions.

A personal Elixir/OTP game-automation bot for a 2D MMORPG, using screen capture and synthetic input on macOS. It features a supervised process fleet, pure decision logic, and fail-safe actuation controls.

findDupes is a Go command-line tool that finds duplicate files by SHA-256 content hash across one or more directories concurrently, filtering candidates by file size and a 4 KiB prefix hash before fully hashing matches.

Swoole is an event-driven, asynchronous, coroutine-based concurrency library for PHP, offering coroutines, runtime hooks that convert blocking I/O, TCP/HTTP/WebSocket servers, clients, timers and channels.

Effect is a comprehensive TypeScript library designed for building robust, type-safe, production-grade applications with built-in support for typed errors and dependency injection.

Simgit provides disk-efficient, isolated Git worktrees using copy-on-write (CoW) for running multiple AI agents or parallel development on a single repository. It leverages native filesystem features (APFS, reflink) or fuse-overlayfs to minimize disk usage, offering significant savings compared to full worktree copies.

Yew is a Rust/Wasm framework for building multi-threaded front-end web apps. It uses a JSX-like macro for HTML in Rust, minimizes DOM calls, supports web workers, and interoperates with JavaScript and NPM packages.

Actix is an actor framework for Rust that enables building concurrent applications using the actor model, featuring async and sync actors, typed messages, actor supervision, and integration with the Tokio runtime on stable Rust 1.88+.

NeoHaskell is a beginner-friendly Haskell dialect designed for productivity, with tooling, testing, and documentation built-in for easy app development.

Promise is a statically-typed programming language designed for AI agents to write correct, maintainable code. It features explicit ownership, goroutine-style concurrency, algebraic error handling, generics, and pattern matching. Compiles natively to LLVM for Linux, macOS, Windows, and WASM.

Hatchet is an open-source orchestration engine for background tasks, AI agents, and durable workflows. Supports Python, TypeScript, Go, and Ruby via self-hosting or Hatchet Cloud. Features task retries, cron jobs, DAGs, real-time monitoring, and multi-tenancy.
