    Python Playground▲12

    Hey HN! I built Python Playground, a Chrome extension that gives you a ready-to-use Python environment right in your browser - no installation needed. It runs Python locally via Pyodide (WebAssembly) with most popular libraries included out of the box, plus a package manager to install additional modules from PyPI. The environment supports inline data visualization with Matplotlib and Plotly, file upload/download through a sandboxed filesystem, and the ability to save and reload snippets. Everything executes entirely on the client, so it works offline and nothing ever leaves your…

    Run – a CLI universal code runner I built while learning Rust▲96

    Hi HN — I’m learning Rust and decided to build a universal CLI for running code in many languages. The tool, Run, aims to be a single, minimal dependency utility for: running one-off snippets (from CLI flags), running files, reading and executing piped stdin, and providing language-specific REPLs that you can switch between interactively. I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL…

    Python running on the Super Nintendo (in-browser demo)▲7

    MicroPython (lexer, compiler and VM) on the SNES: 3.58 MHz 65816, 56 KB Python heap, 16-bit int. The REPL runs right inside the post via EmulatorJS and also works on real hardware via flashcart. I did this as a benchmark for Claude Fable. When the export ban hit, switching to Opus got the project stuck for three weeks; Fable came back and found the real bug in ninety minutes. Along the way: 23 compiler bugs and 4 MicroPython bugs, each root-caused with a minimal reproducer and filed upstream. If you run it on real hardware, I want a picture!
