PC-BSD - Open Source BSD Kernel Based OS

Open Source Utilities Software

PC-BSD, or PCBSD, is a Unix-like, desktop-oriented operating system built upon the most recent releases of FreeBSD. It aims to be easy to install by using a graphical installation program, and easy and ready-to-use immediately by providing KDE SC as the pre-installed graphical user interface. It provides official binary nVidia and Intel drivers for hardware acceleration and an optional 3D desktop interface through Kwin, and Wine is ready-to-use in running Microsoft Windows software. PC-BSD is able to run Linux software, in addition to FreeBSD ports, and it has its own PBI package management system that allows users to graphically install pre-built software packages from a single downloaded executable file, which is unique for BSD operating systems.

Open Source Operating System

TinyOS is a open source component-based operating system and platform targeting wireless sensor networks (WSNs). TinyOS is an embedded operating system written in the nesC programming language as a set of cooperating tasks and processes. It is intended to be incorporated into smartdust. TinyOS started as a collaboration between the University of California, Berkeley in co-operation with Intel Research and Crossbow Technology, and has since grown to be an international consortium, the TinyOS Alliance.

Open Source Operating System

Haiku is an open source operating system currently in development that specifically targets personal computing. Inspired by the Be Operating System, Haiku is a fast, efficient, simple to use, easy to learn, and yet very powerful system for computer users of all levels. Additionally, Haiku offers something else over other open source platforms which is quite unique: The project consists of a single team writing everything from the kernel, drivers, userland services, tool kit, and graphics stack to the included desktop applications and preflets. This allows Haiku to achieve a level of consistency that provides many conveniences, and is truly enjoyable to use by both end-users and developers alike.
