DotGNU

DotGNU is a decommissioned part of the GNU Project that aims to provide a free software replacement for Microsoft's .NET Framework by Free Software Foundation. Other goals of the project are better support for non-Windows platforms and support for more processors.

The main goal of the DotGNU project code base was to provide a class library that is 100% Common Language Specification (CLS) compliant.

Main development projects

Portable.NET

DotGNU Portable.NET, an implementation of the ECMA-335 Common Language Infrastructure (CLI), includes software to compile and run Visual Basic .NET, C#, and C applications that use the .NET base class libraries, XML, and Windows Forms. Portable.NET claims to support various instruction set architectures including x86, PPC, ARM, and SPARC.

phpGroupWare

phpGroupWare, a multi-user web-based GroupWare suite, which also serves to provide a collection of webservice components that can be accessed through XML-RPC so that can easily integrate them into webservice applications.

Wildebeest

The wildebeests, also called gnus or wildebai, are a genus of antelopes, Connochaetes. They belong to the family Bovidae, which includes antelopes, cattle, goats, sheep and other even-toed horned ungulates. Connochaetes includes two species, both native to Africa: the black wildebeest, or white-tailed gnu (C. gnou); and the blue wildebeest, or brindled gnu (C. taurinus). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black wildebeest changed more in order to adapt to its open grassland habitat in the south. The most obvious way of telling the two species apart are the differences in their colouring and in the way their horns are oriented.

In East Africa, the blue wildebeest is the most abundant big game species and some populations perform an annual migration to new grazing grounds but the black wildebeest is merely nomadic. Breeding in both takes place over a short period of time at the end of the rainy season and the calves are soon active and are able to move with the herd. Nevertheless, some fall prey to large carnivores. Wildebeest often graze in mixed herds with zebra which gives heightened awareness of potential predators. They are also alert to the warning signals emitted by other animals such as baboons. Wildebeest are a tourist attraction but compete with domesticated livestock for pasture and are sometimes blamed by farmers for transferring diseases and parasites to their cattle. Some illegal hunting goes on but the population trend is fairly stable and some populations are in national parks or on private land. The IUCN lists both species as being of "least concern".

GNU

GNU ⁱ/ɡnuː/ is an operating system project and an extensive collection of computer software. GNU is composed wholly of free software.

GNU is a recursive acronym for "GNU's Not Unix!", chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code. The GNU project includes an operating system kernel, GNU HURD, which was the original focus of the Free Software Foundation (FSF). However, non-GNU kernels, most famously the Linux kernel, can also be used with GNU software; and since the kernel is the least mature part of GNU, this is how it is usually used. The combination of GNU software and the Linux kernel is commonly known as Linux (or less frequently GNU/Linux; see GNU/Linux naming controversy).

GNU is still missing some components to make it a full operating system that a person can readily install and use on a computer, specifically a fully functioning kernel. In practice, most usable GNU-based operating systems are Linux distributions. They contain the Linux kernel, GNU components and software from many other free software projects.

Mach (kernel)

Mach (/mʌk/) is a kernel developed at Carnegie Mellon University to support operating system research, primarily distributed and parallel computing. Mach is often mentioned as one of the earliest examples of a microkernel. However, not all versions of Mach are microkernels. Mach's derivatives are the basis of the modern operating system kernels in GNU Hurd and Apple's products OS X, iOS, tvOS and watchOS.

The project at Carnegie Mellon ran from 1985 to 1994, ending with Mach 3.0, which is a true microkernel. Mach was developed as a replacement for the kernel in the BSD version of Unix, so no new operating system would have to be designed around it. Experimental research on Mach appears to have ended, although Mach and its derivatives exist within a number of commercial operating systems. These include NeXTSTEP and OpenStep, upon which OS X is based—all using the XNU operating system kernel which incorporates an earlier, non-microkernel, Mach as a major component. The Mach virtual memory management system was also adopted in 4.4BSD by the BSD developers at CSRG, and appears in modern BSD-derived Unix systems, such as FreeBSD.
