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. -

MINIBIAN image for Raspberry Pi
MINIBIAN is a MINImal RaspBIAN-based Linux image for Raspberry Pi
The main focus is to have a small, updated and stable distribution that is fully compatible with official Raspbian image, without GUI and unneeded tools. So this image is perfect for embedded projects, or wherever you need to use all RPi resources for your specific tasks. The main advantage is that MINIBIAN has a very small footprint, boots in some seconds and uses just few of precious RPi RAM. Unlike other similar projects, MINIBIAN has not been obtained purging unneeded packages from original image, neither recompiling the source code: it’s just a customized Raspbian installation obtained from the same repository used for official RPi image. So kernel and binary files are exactely the same you will find on standard image, with the difference that MINIBIAN fit on 1GB SD Card, is fastest, and updated more often. -

MultiBootUSB-Live
Portable System for installing many Linux Distros on to a Pen drive
This project provides a Live DVD for the multibootusb program, for installing multiple Linux Distros on to a single Pen drive and able to boot from it. This is a portable system, which does not require any installation. Video Below. This system can be started through the DVD Drive OR VirtualBox (See Below). This .iso file can also be written on to a small dedicated pen drive ( ~ 1 GB ) through this DVD's multibootusb program and further used for writing linux images on to other pen drives ( not on the same ! ) thereby making everything portable. Note: Click "+ Other Locations" on the file manager for opening local disks, while browsing for images to write through this dvd's multibootusb program. Also note that the pen drive needs to be in fat32 format for proper booting. if in other formats, for eg. ntfs, you can use the GParted program that is in this dvd, to reformat it to fat32 ( will cleanup all data ). Watch https://www.youtube.com/watch?v=CjQRkISnHQ4 before format. See Wiki -
