A collaborative "Fake OS" running in the browser, with a custom backend written in Odin for raw performance. All connected users share the same in-memory Virtual File System and can interact in real-time using terminal commands.

• Backend: Odin (Core, WebSockets, HTTP)
• Frontend: HTML/CSS, Vanilla JS, xterm.js for the terminal interface

• Environment setup (Odin 2026-04).
• Implement base HTTP/WebSocket server in Odin.
• Frontend creation (xterm.js + WebSocket connection).
• Reverse Proxy (Nginx) & SSL Setup (Certbot Let's Encrypt).
• In-memory Virtual File System (VFS) implementation (basic).
• Basic command parsing (ls, cat, echo, whoami, wall).
• Asynchronous service execution (Systemd) with automatic restarts.
• Complete directory system (mkdir, cd, pwd, rmdir) and memory management (Extended VFS).
• Advanced TAB Autocomplete feature (for commands and files/folders).
• Account system and prompt customization (login/nick and color), interconnected with broadcast events (wall).
• Commands with global visual impact (clearall for all visitors and matrix for responsive HTML5 Canvas digital rain animations on all screens).

• More advanced file editing system (e.g. multi-line text editor like nano/vim).
• Persistent state (saving the VFS to disk instead of memory).
