Hello, I created a browser-based operating system called CinnaOS. It features a DIY-made command prompt; this entire project was handcrafted. Thank you for visiting. I spent two full days on this project, and I will provide better updates soon. This is the 3rd version (version 3.0). lol trololo

NEVER RUN sudo rm -rf /* let me explain so I was dual-booting Windows 10 and Linux Ubuntu. I was curious about sudo rm -rf /* and then I typed it and pressed enter and it started to delete as many files in its path and then even touched windows 10 and bricked my pc now no ssd shows up and it keeps booting in bios/uefi and yea :/ Not everything in life will be good.

The owner reviewing CinnaOS: I reviewed cinnaos.neocities.org, and it's a charming simulated web-based operating system! The interface features a retro aesthetic, complete with a taskbar and various applications, including Terminal, Notepad, Clock, Calendar, Settings, and Paint. Each app opens within the browser, providing a nostalgic desktop-like experience. cinnaos.neocities.org The Paint application allows for drawing directly on the canvas, and the Save Drawing button functions correctly, enabling you to download your artwork as a PNG file. The overall design is cohesive and user-friendly, making it a delightful project to explore.
