This is an introductory textbook on systems programming, designed to demystify low-level computing concepts. It provides a structured, open-source curriculum for students learning about operating systems, memory management, and hardware interaction. Primarily created for University of Illinois courses, it's a valuable resource for any student or educator in computer science and engineering.

Madeira is a project that enables you to play x86-64 Windows PC games on non-jailbroken iOS devices. It solves the problem of iOS's locked-down ecosystem by combining FEX-Emu, Wine, and DXMT to create a compatibility layer. This is for gamers and enthusiasts who want to access their Windows game library directly on their iPhone or iPad.

codebase-memory-mcp is an MCP server that indexes repositories into a persistent knowledge graph of functions, classes, and dependencies. It solves the problem of AI agents inefficiently reading files one-by-one, enabling structural queries with ~120x fewer tokens. It's for developers and teams using AI coding assistants like Claude Code who need fast, local, and deep codebase understanding.

colibrì is a pure C, zero-dependency engine that runs frontier-scale Mixture-of-Experts models on hardware you already own. It solves the problem of massive model size by streaming expert weights from disk instead of loading them entirely into RAM, enabling a 2.8-trillion-parameter model to run on a 32 GB machine. It's for developers, researchers, and anyone curious who wants to open up and run state-of-the-art AI models outside of sealed datacenters.

ArmorPaint is a standalone, GPU-accelerated software for physically-based texture painting on 3D models. It solves the problem of slow, complex texturing workflows by offering a node-based, real-time painting experience with ray-traced baking and viewport rendering. It's designed for 3D artists, texture painters, and game developers who need to create high-quality materials and textures efficiently, from indie creators to professionals.

Dopamine is a semi-untethered jailbreak tool designed for iOS versions 15 through 26.0.1. It solves the problem of users wanting to customize and gain deeper control over their iPhones and iPads beyond Apple's standard restrictions. This tool is primarily for advanced iOS users, developers, and enthusiasts who seek to modify system behavior, install unauthorized apps, and personalize their device's core functionality.

ds4 is a local inference engine for DeepSeek 4 Flash and PRO models. It solves the problem of needing cloud API access or expensive infrastructure by enabling efficient local deployment. It's designed for developers and researchers who want to run state-of-the-art LLMs on their own hardware with support for Metal (Apple Silicon), CUDA (NVIDIA), and ROCm (AMD) platforms.

Lighthouse is a game engine built for developers and creators to build 3D games and interactive experiences. It solves the problem of complex, proprietary engines by providing a free, open-source alternative with a focus on performance and ease of use. It's ideal for indie developers, hobbyists, and educational projects looking for a powerful yet accessible toolset.

Microsoft PowerToys is a set of free, open-source utilities designed to enhance and customize the Windows user experience. It solves common productivity bottlenecks by providing tools for window management, file renaming, color picking, and more, right out of the box. It's for power users, developers, and anyone looking to streamline their daily tasks and unlock advanced Windows functionality.
