Linux running in a PDF? This hack is as bizarre as it is brilliant

A high school student created a Linux environment that runs within a PDF file viewed in Chrome. The system uses a JavaScript-based RISC-V emulator to run a stripped-down Linux kernel, displaying output as ASCII characters. Users can access a terminal prompt and execute basic Linux commands using an on-screen keyboard. While slow and potentially raising security concerns, this project demonstrates the possibility of adding computational power to PDFs. Future applications could include interactive documents with calculation and automation capabilities.
