The Working Overloaded Linux Kernel (WOLK) project provides stable and development kernels for either server or testing purposes. These kernels provide a server kernel and also a service for developers and end users who can't be up-to-date with the latest kernels/patches but want to test new kernel features. Patches may be added upon request.
Visopsys is an alternative operating system for PC compatible computers. Under development since late 1997, this system is small, fast, and open source. It features a simple but functional graphical interface, real preemptive 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 or floppy disk.
User-Mode Linux lets you run Linux inside Linux. It is a safe, secure way of running Linux versions and Linux processes. Run buggy software, experiment with new Linux kernels or distributions, and poke around in the internals of Linux, all without risking your main Linux setup. User-Mode Linux gives you a virtual machine that may have more hardware and software virtual resources than your actual, physical computer. You can assign your virtual machine only the hardware access you want it to have. With properly limited access, nothing you do on the virtual machine can change or damage your real computer or its software.
NetBSD is a free, secure, and highly portable Unix-like operating system available for many platforms, from large-scale server systems to powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vivid international community. Many applications are easily available through pkgsrc, the NetBSD Packages Collection.
WinDriver automates and simplifies the development of user-mode Linux device drivers for PCI, CardBus, ISA, PMC, PCI-X, PCI-EXPRESS, and CompactPCI as well as USB 1.1/2.0. No internal OS knowledge or kernel level programming is required. It supports kernel 2.0.31 and above, including embedded Linux, x86 and PowerPC processors, and any 32-bit development environment supporting C or Delphi. Applications are source code compatible across Windows 98/Me/NT/2000/XP/XP Embedded/Server 2003/CE, Linux, Solaris, and VxWorks.
WANPIPE S-series is a family of intelligent multi-protocol WAN and ADSL adapters that support data transfer rates up to 8Mbps. All WAN protocols supported by WANPIPE are implemented in firmware and run on the card. An advantage of an intelligent adapter is that it offloads the system CPU and improves stability. By adding a Sangoma WAN/ADSL component to the Linux kernel, one can create a powerful multi-T1/ADSL router/firewall with proven reliability of Linux. Sangoma S-series cards support an optional on board T1/E1 CSU/DSU that eliminates all external components of a traditional routing solution: i.e. T1/E1 line can be directly connected to the card. WANPIPE supports the following protocols, ATM, ADSL, Frame Relay, PPP, MULTILINK PPP, CHDLC, X25(API), BitStreaming (API), BiSync(API), and SDLC(API). Furthermore, WANPIPE supports custom API development such as: Credit card verification, Voice-over IP, Satellite Comm. All device drivers are part of the standard Linux Kernel distribution.
Squashfs is a highly compressed read-only filesystem for Linux. It uses zlib to compress files, inodes, and directories. All blocks are packed to minimize the data overhead, and block sizes of between 4K and 1M are supported. It is intended to be used for archival use, for live CDs, and for embedded systems where low overhead is needed.
The ENBD (Enhanced Network Block Device) is an industrial-strength version of the Linux kernel NBD. It makes a remote disk look like a local block device, allowing cheap and safe realtime mirrors to be built over the net. It features internal block-journalling and multichannel failover.
