Initially, I created this project four years ago as a way to learn Python. At that time, it wasn't named ProcyonCLS or DonutCLS; I simply referred to it as Simple CLI. As I continued to learn, I renamed it Py-DOS, even though it wasn't an actual operating system. Eventually, I stopped working on it, thinking it was pointless—after all, who uses a CLI application that does nothing in the age of GUIs? However, last month, after completing my final exam for the third semester of my BCA degree, I revisited the project out of boredom. This time, instead of a single Python file, I developed a bootloader, kernel, and shell to demonstrate to some friends the basics of how a real operating system functions. It wasn't a true OS, but it served as a useful illustration. Later, I decided to upload it to my GitHub, regardless of whether it would be used or not. The first GitHub release of ProcyonCLS was version 0.5, back when the release name '2025' had not been established, and it was simply known as "ProcyonCLS Codename Munnar."
In the late 1990s, Microsoft embarked on an ambitious project to revolutionize its operating systems. Codenamed Neptune , this project aimed to create a consumer-oriented version of Windows based on the Windows NT codebase. Although it never saw an official release, Neptune played a crucial role in shaping the future of Windows. The Genesis of Neptune Neptune was conceived as a successor to Windows 98 and Windows Me. The goal was to merge the stability and advanced features of Windows NT with a user-friendly interface suitable for home users. The project began in 1999 and was led by a dedicated team within Microsoft. Key Features and Innovations Neptune introduced several groundbreaking features that were ahead of their time: Activity Centers : One of the most notable innovations was the introduction of Activity Centers. These task-based user interfaces focused on daily activities such as browsing the internet, communication, document management, and entertainment. The idea was to...
