This article introduces Codebase Navigator, a tool designed to simplify the process of understanding large, unfamiliar GitHub repositories. By pasting a repository URL, users can interact with an AI assistant that provides a live dependency graph built from actual import statements, a code viewer, and a full file tree. Unlike standard AI assistants that often hallucinate file paths, this tool uses real data to visualize connections between files in real time. Built with a modern tech stack including Next.js, CopilotKit, and React Flow, the project can be run entirely for free using local LLMs via Ollama. The author provides a deep dive into the architecture, the technical implementation of the dependency resolution, and how the tool maintains state across multiple UI panels.
Developer Lyra Rebane has created an emulator for a basic Intel x86-based computer entirely using CSS, proving the language's Turing-completeness. The emulator runs in-browser and requires no JavaScript, though a script tag is used for a faster clock. It's not practical for performance, but a fun demonstration of what's possible with CSS.
Paris-based Open Tools is developing an open-source inkjet printer that uses standard mechanical components and refillable ink cartridges, controlled by a Raspberry Pi Zero W. It can print on both sheets and rolls of paper, automatically cutting the latter to size, and aims to provide a repairable, upgradeable alternative to traditional printers.
