The AROS Research Operating System is an effort to implement an Open Source and portable operating system that is compatible with AmigaOS(TM). Originally, it was meant as a direct reimplementation, but already has features not existing in AmigaOS.
Syllable Desktop is a complete operating system that is easy to use, powerful, lightweight and extraordinarily fast and responsive. It has its own kernel, filesystem, GUI and applications. Syllable Server is a matching small and efficient Linux server.
An open source identity and IT infrastructure management solution
Univention Corporate Server (UCS) is the free to use, innovative platform to efficiently operate and manage server applications and complete IT infrastructures. UCS is optimally suited for the management of distributed, heterogeneous and virtualized IT environments, no matter whether you deploy Microsoft Windows, Mac OS X or Linux systems. The integrated identity and infrastructure management system allows the secure administration of applications and provision of infrastructure services as well as the central, cross-location and cross-platform management of server and desktop systems via an intuitive web interface. Thanks to open interfaces and easy-to-use connectors, UCS can be effortlessly integrated in existing environments. Via the integrated App Center, it offers a large number of enterprise applications, which can be operated with a few clicks. Extensive Active Directory functions allow both the integration as well as the migration from Microsoft.
Alternative operating system for x86 computers
Visopsys is an alternative operating system for PC compatible computers. In development since 1997, this system is small, fast, and open source. It features a simple but functional graphical interface, pre-emptive multitasking, and virtual memory. Though it attempts to be compatible in a number of ways, Visopsys is not a clone of any other operating system. You can demo the distribution from a “live” CD/DVD or floppy disk
Written in pure ASM and Exode with cloud computing in mind.
Cloudium OS is being written in pure ASM. It's designed for speed and ease, having cloud computing in mind. It also is secure (without requiring constant user input like Windows). But, how are we going to do this? Well every os wants/says these kind of things, so to accomplish our goals we follow these simple rules: keep it simple (that's way better then these complex interfaces etc. almost nobody wants), generalize (this makes things easier and more useful without extra complexity) and be inventive (sometimes doing it the classical way just doesn't work). Note: development peace will be temporarily lowered until February the fifth. Please check out our OS and Project site!
The CK 64-Bit Kernel Operating System
This project is a implementation of layers. Use Virtual machines & virtual adapters alike an onion! Another operating solution instead of Microsoft Windows Server operating system. It is to be used via remote controlling. The special new "Cktool32" will make it easy to handle *Ck64Krnl*.
New Linux Based OS primarily for smart devices and PDA's, laptops, and eventually desktops. It offers an alternative to the "embedded" approach. All OS versions and applications will be hosted and then made available to the subscribers of cloud svs
An operating system written in C & assembly.
An operating system written in C & assembly. FruityOrange uses the concept of a monolithic kernel and GRUB as bootloader for the kernel and some modules. There is still no release. If you want do try the development-version, get the Sourcecode and build by yourself!
This project intends to port the "Android Open Source Project "on the Samsung Galaxy GT-i7500. We are working with the Eclair 2.1 branch of the Android Open Source Project. This project use modified framework, core and settings from Cyanogen.
Customize Kernel 64-Bit Operating System
An Open Source Solution usable instead of Microsoft Windows. The ck64os enables server operating system tasks but is downgradable to an End-User software distribution for Tablet-PCs. It's Microsoft Windows application programming interface compability bases on incorporated virtualization layers.
