Cooperative Linux is the first method for optimally running Linux on Windows and other operating systems natively. It is a port of the Linux kernel and support code that allows it to run cooperatively without emulation along with another operating system.

This is a small library that allows comunicating with a Webasto (tm) W-Bus capable car heating system. Runs on Personal Computers or for embedded devices (slim design). Easily portable. Includes a Heater manager, heater controller program and more. The GIT repository (CVS is deprecated) also includes a control unit application to control W-Bus capable devices, a W-Bus compatible heater unit firmware application and a heater simulator for testing purposes. Also, a serial port loop back driver for linux is included to simulate OBD II K-Line adapters.

This project reimplements from scratch the RPL language made popular by HP programmable calculators, in portable C/C++. The main goal is to release a complete computing environment for various targets. There's currently 4 active targets: the HP 50g, HP39gs and HP40gs calculators and a PC simulator (see the downloads section!). Other ports are planned for the future.

TinyOS is an operating system for embedded sensors and networks. Versions 2.0 and later of TinyOS should be downloaded from www.tinyos.net.

AO-RTOS is a pure object-oriented small footprint real-time operating system for embedded devices. The project is using Active Object (or Actor) concurrency model and finite state machine (FSM) design template as implementation base.

TORO is demonstrating an innovative operating system by integrating at the same ring level both kernel and the user application server. The threads of the user application server are distributed evenly on all CPUs and running independently in parallel. The memory model chosen is NUMA without pagination. During the initialization, the memory is divided proportionally for each processor installed on the system. When a thread needs memory, the memory allocator returns a free block of memory depending on which CPU the thread is running. In the same way, TORO can dedicate resources to specific processor, i.e. a FileSystem. This only CPU then can access to this instance of FileSystem. The scheduler is based on the cooperative threading model, therefore due to this design, TORO can migrate threads between CPUs and send messages between threads without using any lock instruction. TORO is well suited for integrated system to run at high pace application servers like web servers.

xinco [eXtensibe INformation COre] is a powerful Web-Service based Information and Document Management System (DMS) for files, text, URLs and contacts, featuring ACLs, versioning, full text search, an FTP-like client (easy install, J2EE+MySQL/PostgreSQL)

SuperWaba is a Virtual Machine for handhelds. Runs in PalmOS, Windows CE, Win32, and is fully emulated under JDK/browser. Supports Exceptions, has a complete set of UI controls (Palm/WinCE), double and long, grayscale/color, sockets/serial/IR/Bluetooth

UZIX is a UNIX Implementation for MSX machines, based on UZI written by Douglas Braun. It is a multiuser, multitask operating system, implementing almost all 7th Edition AT&T UNIX kernel functionality.

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

UFFS: Ultra-low-cost Flash File System, designed for NAND flash working in embedded system. UFFS typically consumes less then 200K ram for 1Gb(page 512)/4Gb(page 2K) NAND flash. It supports direct flash interface, works with or without OS.

Boiler-template (source) file generator. Automates (source) file generation from template files: speeds up developement of redundant or re-usable software and more. An example template for Linux Kernel Device Drivers generation, is included.

Neptune is a kernel and a complete operating system. The Neptune kernel can be used in any of your projects and the Neptune operating system depends on the Neptune kernel. For information on customizing Neptune, go to: http://neptuneos.eu.pn/devel.html

OSLib is a collection of low level functions aimed to help programmers in developing system software, ranging from small programs for embedded systems to complex Operating System kernels.

Gobudgie is using the powerfull Budgie desktop combined with the Ubuntu base. The user interface is designed for Android users so we're using a material theme. Gobudgie offers several ways to easily access or install applications. We integrated the Chromium OS Web Store the standard Ubuntu Software Center, an Android App runtime, PlayOnLinux and Wine.

The cache-optimized concurrent skip list is a set of algorithms for maintaining dynamic ordered mappings. Top-down balancing algorithms minimize cache-misses while using a per-node read-write spinlock to coordinate shared access. Designed for Linux 2.4.

Covert Linux is technology of instalation for Linux without repartition the disk and running from native system, e.g. you can install Linux from ,say, Windows by grabbing some SETUP.EXE, launching it and then clicking on desktop icon.

Dreamos is an operating system developed on Sega Dreamcast to be ported to an array of embedded devices. The goal of the project is to be able to run non-ported Unix programs on the Sega Dreamcast and other embedded devices with ease and POSIX compliance

The L4Ka microkernel is an L4 compatible microkernel running on multiple platforms (x86, ARM, MIPS, PPC, 68K). Its official name is now L4Ka::Hazelnut. This kernel has been discontinued in favor of L4Ka::Pistachio. See http://l4ka.org/

MikeOS is a an open source 16-bit operating system for x86 PCs, written in assembly language, which boots from a floppy disk or CD-ROM. It is designed as a learning tool for x86 assembler and basic OS design.

Sets out to be an innovative new operating system while retaining compatibility with POSIX and Win32

XOA-DOS is a DOS-like operating system implemented in x86 assembly, syntax NASM. It intends to be an educational project.

Committed to the development of fundamental ACPI (Advanced Configuration and Power Interface) components for Linux. This includes a generic ACPI table parser, AML interpreter, bus and device drivers, policy, user interface, and support tools.
