FOUND: Minimal linux os runs in a 6mb pdf document in chrome linuxpdf leverages risc v emulator - What They Never Told You

Linux
LinuxPDF screens, from a project by Ading2210.

A version of the Linux operating system can now be run inside a PDF opened by a Chromium-based browser. The brains behind the coding gymnastics involved in this 6MB LinuxPDF project belong to high school student Ading2210. If the name is familiar, it might be because the same person created DoomPDF, which we reported on in January.

Ading2210 explains that Linux runs in the PDF within a modified version of the TinyEMU RISC-V emulator. The developer notes that LinuxPDF "works in a very similar way to my previous DoomPDF project." Like DoomPDF, this Linux-in-a-doc project also has a bit of a performance problem, as it is claimed to be "over 100x slower" than it should be.
