JSLinux boots Linux entirely in the browser

Summary

Fabrice Bellard runs a Linux kernel including a user environment on a JavaScript-emulated CPU directly in the browser. A sufficiently general platform can even run systems it was never designed for. Slow but complete emulation is often more valuable for learning and portability than fast specialised simulation.

Ideas

  • A JavaScript emulator fully reproduces the processor, memory and the necessary devices.
  • Linux boots without a plugin and without executing code outside the browser sandbox.
  • The demonstration combines compiler technology, emulation and the web platform into an interactive system.

Recommendations

  • Use browser emulation for reproducible experiments without sensitive data.
  • Compare the emulated architecture, kernel configuration and limits of persistent storage.

htop explained

Pēteris Ņikiforovs explains every htop display and links it with Linux processes, the scheduler, memory management and procfs. /proc/loadavg provides load values, process counts and the most recently assigned PID. PID 1 traditionally belongs to the init process started at boot.
