    Windows 95 in Electron

    Windows 95 in Electron

    Windows 95 in Electron. Runs on macOS, Linux, and Windows

    windows95 in Electron is a quirky, nostalgia-driven project that ports a complete emulation of Microsoft Windows 95 into a desktop application that runs on modern operating systems like Windows, macOS, and Linux. It essentially wraps an emulator — preconfigured to boot Windows 95 — inside a user-friendly app built with web technologies so developers and hobbyists can explore the look and feel of that classic OS without needing legacy hardware or complicated setup. Users can interact with familiar UI elements like the Start menu, File Explorer, and retro applications in a sandboxed environment that evokes early personal computing. Beyond being a playful trip down memory lane, the project demonstrates how emulation can be packaged using modern frameworks & how legacy operating systems can be encapsulated as distributable desktop experiences. It’s become an example of how software preservation and creative programming can intersect, inspiring others to bring historic systems to life.

    AnduinOS

    AnduinOS

    AnduinOS is a custom Ubuntu-based Linux distribution

    AnduinOS is a personal/experimental operating system–style project and collection of components built to explore how a desktop-like environment and tooling could be organized under one coherent repo. It combines configuration, scripts, and UI elements to form a workstation experience that is more opinionated and automation-friendly than a vanilla setup. The project leans toward developer productivity: quick access to tools, reproducible configuration, and a unified place to evolve the environment. Because it is open source, users can inspect how the author wires services, handles packaging, or defines UI/UX conventions. It’s well suited for people who want to understand how to bootstrap and maintain a bespoke, code-driven desktop environment rather than relying on distro defaults. Over time it can serve as a living example of infrastructure-as-code principles applied to a personal OS setup.
