A "Theoretically Secure Operating System", focused on information protection, that is provably secure provided that a specific part of the kernel would be free of bugs.
In particular, bugs in application can't be exploited to attack the system.
Hadie - Hardware Abstracting Device Independent Environment. Or just another micro kernel for embedded devices.
Supported architecture are i8051 (80515c), i166 (XC161CJ), Tricore (TC1775B), m68k (m68332) and i386.
Enhanced version of the standard Linux loopback device that makes the loopback device act more like a hard drive and allows for mounting partitions within a drive image via new loopback device names (/dev/loopa, /dev/loopa1, /dev/loopa2, etc.).
Urinel is a dynamic kernel-less operating system designed for maximum code reuse. This improves the efficiency and stability of the code and reduces the size of applications allowing a wide range of functionality to applications.
A simple operating system made for educational purposes. It will be a 32 bit multitasking open source operating system. Latest release covers interrupt handling, device drivers and shell service.

MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
The Fecundity Project has the purpose of creating a streamlined AMD64 based Operating System. We will hopefully create a stable and secure operating environment, and to investigate orthogonal persistence.
The goal of this project is to develop an Operating System. It will have a NTFS style file system and use a Windows XP compatable hardware driver system. The main focus is to allow common executable formats (windows/unix/ELF).
kissme is a free (GPLed) Java Virtual Machine. It is being developed on GNU/Linux and can run console java applications. kissme is to be used with the GNU Classpath java class library. kissme also provides support for orthogonally persistent java.
A Unix-like (Not compleatly Unix-compatible) Kernel. Right now, we have (very limited support) of 80486+ IBM-PC AT compatibles. Written in C, and assembly. No network support planned for the forseeable future.
Fireball (FSD) Amoeba is a distributed operating system. It collects a huge
varity of single machines connected over a (fast) network to one,
huge computer.It's a full Operating System Distribution. Based on Amoeba,Vrije Universiteit.
LainOS is an OpenSource project that seeks to revolutionize the the user experience by bridging the realm between \"Alien Elegance\" and Human Usability, and thus create a truly new and unique interface that is user savvy and beautiful.
The objective of this project is to provide an optimized TCP/IP stack by eliminating the data copying at the socket interface and implementing a feedback-based adaptive rate-based flow control algorithm to maximize the network bandwidth utilization.
Minerva's primary goal is security. To allow all users to feel safe and secure but have the freedom to do what ever they want. We also want a fast easy way to bring every linux and windows o/s together.
An ambitious project being undertaken by the teens of the UK, accepting new members, to create a stable yet powerful OS targeted at webhosting. And our main aim is to keep it simple for the newbies out there. ;)
The goal of llama-X is to be a cutting-edge desktop operating system for the x86 architecture. A new object-oriented filesystem, and a fresh new desktop paradigm, and an innovative multikernel subsystem are main features of the system.
