The objective of the TPM Emulator project is the implementation of a software-based TPM and MTM emulator as well as of an appropriate TCG Device Driver Library (TDDL).

Haiku is an open-source operating system currently in development designed from the ground up for desktop computing. Inspired by the BeOS, Haiku aims to provide a computing experience that is simple yet powerful, and free of any unnecessary complexities.

Home-made operating system, developed in C and asm for x86 architectures.

This project is aimed at providing (open) software to support pure virtual interface for Linux Kernel. All Linux networking functionality will be supported on these interfaces. For Release 1.1 1) Adds support for connectivity between the vnics of two different systems by way of creating overlays. (VXLAN style) 2) On a virtual environment it can either run on hypervisor or inside a VM (as applicable). - Dipjyoti Saikia (Developer/Admin) <dipjyoti.saikia@gmail.com>

Graphical OS Kernel compiled with gcc 4.6.1 and nasm 2.09.08

HelloOS is a simple free operating system for i386

Nupkux is a small kernel for an Unix-like operating system, developped on x86-architecture. It aims to offer a POSIX-compatible interface.

M String is a microkernel based on some part of oskit libs. It's designed to be small, simple, and have a simple API for server interprocess communication.

portsman is an ncurses based, graphical front-end to manage the FreeBSD (NetBSD & OpenBSD planned) ports collection(s). It behaves like a package manager and comes with many features.

Our mission is to explore and develop new operating system concepts aimed at producing a more efficient computing environment where both the machine and user time are taken in consideration.

Agnix is a small operating system kernel for i386, supporting 32-bit protected memory mode, paging, hardware switched tasks, memory tests, PCI bus, devices, PCI IRQ routing, RT timers and network protocols.

cvsfs4hurd is a translator for the GNU Hurd, which allows to "mount" a CVS module into your local filesystem. It allows to view version controlled files as like they were regular files on your disk, however saving much network bandwidth.

Note: the project is basically dead, as I started rewriting it but I don't have much free time to work on it. It's basically a micro-kernel, but on top of that, instead of having multiple servers running as standalone processes, it has a modular kernel, so that each server is a module of this kernel. The micro-kernel contains only the scheduler, memory management and drivers for high-speed devices (like gigabit ethernet NICs or video cards).

A simple Embedded System Framework that allows rapid development of applications build for AVR family. System is based on a super-loop architecture with check and skip (no-wait) flag event driver system. Supports: UART, SysTick Timer, ADC, SPI, EEPROM, PWM. Also supports: Xilinx FPGA configuration, FPGA SSI interface, smart card reader etc. Tested partially (different modules in each case) on ATMega163/16/32/323/8. Awards CodeProject 2010, Third Prize, Hardware and Device...

Driver module using rtc-driver allowing multiple users to use the real-time-clock. Each task opening the timer device gets its own image of the RTC. Except setting the RTC, all features can be used on a per task basis without frequency restriction.

A basic operating system that can realize some basic functions. It is developing for educational purposes. It is being developed simultaneously with sslib, the Simple Standard Library for developers program no-OS apps, program NuOS commands or program an operating system.

Linux build, cross toolchain & root fs to run on Mikrotik's RB1000 unit

several vaguely related projects worked on by me: a 3d engine with a javascript-like scripting language (pdsys); an older scheme dialect (vmsys); ... (2009-04-28: I have been gone for years, may try to put up some newer stuff...).

μString microkernel is the part of Jari OS project. It's a preemptible, real-time microkernel that used in Jari OS platform.

Jari OS is a real-time microkernel operating system which runs in terms of multi-service architecture. Core system consists of its own microkernel μString, core and system services, set of device drivers launched as trusted services.

U-tube monitors the memory usage of each VM to detect its memory pressure, and periodically adjusts its memory allocation via memory hotplug. It is implemented as a loadable device driver to coordinate guest OS’ MMU with underlying hypervisor. In contrast to the popular ballooning mechanism, memory hotplug can dynamically expand a guest OS’s physical memory space beyond its maximum configured at booting time.
