A Linux operating system targeting embedded devices
OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned. -

Design OS
The missing design process between your product idea and your codebase
Design OS is an open-source product planning and UI design framework that sits at the intersection of design thinking and generative AI, guiding creators through a repeatable process from product idea to structured design deliverables. It fills what the maintainers describe as the “missing design process” in AI-first development, helping users define product visions, model data, map user flows, and lay out interfaces before a coding agent begins implementation. The tool is poised to produce production-ready UI components and artifacts that any AI coding tool can consume, encouraging a disciplined front-to-backend workflow that avoids disjointed, reactive design prompts. Design OS emphasizes clarity of intent, consistency of design systems, and exporting usable components rather than just static mockups, which aligns better with automated build pipelines and agent-driven development. -

Debian 13 Mate
Debian Trixie with the Mate desktop environment
EFI SUPPORT: Download the efi iso if you need efi support here: https://sourceforge.net/projects/debian-mate/files/current/ This is debian 13 mate. Built with debian tools, packages, and currently based on the stable branch (Trixie). Here I try not to use software from outside of the debian repositories. For all intents and purposes, this is just debian paired with the mate desktop environment with a lot of hardware support taken care of. Debian mate doesn't force you into new conformancy. We use the mate desktop environment here; no gnome 4 or unity for anyone. With a start menu and a taskbar, you're good to go. This is just another decent desktop use operating system, but better. Take a good long stare at my packages (check readme.txt). -
