...It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. A failure or crash of one component does not directly harm others. HelenOS is therefore flexible, modular, extensible, fault tolerant and easy to understand. HelenOS does not aim to be a clone of any existing operating system and trades compatibility with legacy APIs for cleaner design. Most of HelenOS components have been made to order specifically for HelenOS so that its essential parts can stay free of adaptation layers, glue code, franken-components and the maintenance burden incurred by them.

...The name XNU stands for X is Not Unix, highlighting its origin as a combination of multiple kernel technologies—primarily the Mach microkernel from Carnegie Mellon University, integrated with substantial components from FreeBSD and Apple’s proprietary IOKit driver framework. This hybrid architecture merges the microkernel model’s message-passing flexibility with the monolithic performance and direct hardware control typical of Unix-like systems. XNU handles essential kernel responsibilities such as memory management, multitasking, interprocess communication (IPC), device I/O, system calls, security enforcement, and scheduling across both single and multi-core architectures.

resea is a small, message-passing-based operating system kernel designed with microkernel principles in mind. Written in C with minimal dependencies, it emphasizes modularity, isolation, and simplicity. resea includes a basic POSIX-like interface and supports multitasking, IPC, and user-space services. It serves as both a microkernel OS experiment and a platform for learning about low-level system design without the complexity of larger operating systems.

KISS'em is an written in C, delivering something similar to object by kernel. Each kernel module could create object and one object could have many interfaces. For example filesystem could be accessed as an file (block device) or as filesystem, referencing to the same object. KISS'em will have webassembly support with support swap webassembly program memory.

This project is an attempt to design an message passing microkernel-based Operating System for the ZX Spectrum +3e computer equipped with ZXMMC mass storage device. It was made mostly for PoC purpose.

'finddouble' application searches into a directory and all its sub directories. If it finds several times the same file, a warning message is displayed, but no other action is taken. It's main use is to help you optimize you disk usage.
