Tilck
A Tiny Linux-Compatible Kernel
Tilck is a tiny, monolithic operating system kernel designed to be partially compatible with Linux at the binary level while maintaining extreme simplicity, low latency, and minimal resource usage. It is built primarily as an educational project, allowing developers to experiment with kernel development while still being able to run real Linux user-space applications without modification. The kernel is written in C and designed to run on architectures such as i686 and RISC-V, with future plans for broader hardware support. One of its defining characteristics is its deterministic behavior and very small memory footprint, enabling it to run on systems with extremely limited resources. Unlike Linux, tilck intentionally avoids complexity and large-scale features, focusing instead on clarity, robustness, and ease of understanding. It includes its own bootloader and supports integration with existing ones like GRUB, making it flexible for experimentation. -

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). -

Exton|OS
Exton|OS 64 bit based on Ubuntu/Debian with KDE Plasma 4:6.6.2
ABOUT Exton|OS is based on upcoming Ubuntu 26.04 LTS ("Resolute Raccoon") 64 bit and Debian "Sid". IMPORTANT ABOUT REFRACTA TOOLS Refracta tools are pre-installed in Exton|OS . Use Refracta Snapshot to create your own live installable Ubuntu 26.04 system. RUNS FROM RAM Another great thing is that Exton|OS can run from RAM. Use Boot alternative 2 (Load to RAM). When the system has booted up you can remove the disc (DVD/CD) or USB stick. You'll need at least 6 GB RAM to run Exton|OS that way. I.e. super fast! USB installation To enable persistence you can install Exton|OS to a USB stick in the same way as a hard drive installation. You can use Refracta Installer. ANDROID STUDIO You can emulate different Android systems (with GAPPS - Google Play). If you have plenty of RAM you can do it live. I.e. while running Exton|OS from a USB stick. You can't do it in VirtualBox/VMware. KERNEL Kernel 6.19.8-amd64-exton-os is used. -
