Overview

C# Open Source Managed Operating System (Cosmos) is a toolkit for building GUI and command-line based operating systems, written mostly in the programming language C# and small amounts of a high level assembly language named X#. Cosmos is a backronym, in that the acronym was chosen before the meaning. It is open-source software released under a BSD license. , Cosmos encompasses an ahead-of-time (AOT) compiler named IL2CPU to translate Common Intermediate Language (CIL) into native instructions. Cosmos compiles user-made programs and associated libraries using IL2CPU to create a bootable native executable that can be run with no support. The resulting output can be booted from a USB flash drive, CD-ROM, over a network via Preboot Execution Environment (PXE), or inside a virtual machine. Recent releases also allow deploying to certain x86 embedded devices over Universal Serial Bus (USB). While C# is the primary language used by developers (both on the backend and by end users of Cosmos), many CLI languages can be used, provided they compile to pure CIL without the use of Platform Invocation Services (P/Invokes). Cosmos is mainly intended for use with .NET. Cosmos does not aim to become a full operating system, but rather a toolkit to allow other developers to simply and easily build their own operating systems using .NET. It also functions as an abstraction layer, hiding much of the inner workings of the hardware from the eventual developer. Older versions of Cosmos were released in Milestones, with the last being Milestone 5 (released August 2010). More recently, the project switched to simply naming new releases after the latest commit number. Releases of Cosmos are divided into two types: the Userkit, and the Devkit. The Userkit is a pre-packaged release that is updated irregularly, as new and improved features are added. Userkits are generally considered stable, but do not include recent changes and may lack features. The Devkit refers to the source code of Cosmos and must be built manually. The Devkits are usually somewhat stable, but they may have some bugs. The Devkit can be acquired on GitHub and uses Git as the source control management. Most work on Cosmos is currently aimed at improving debugger functionality and Microsoft Visual Studio integration. Kernel work is focused on implementing file systems, memory management, and developing a reliable network interface.

Notable quotes

“It was Pythagoras who first called heaven kosmos, because it is perfect, and "adorned" with infinite beauty and living beings.”
— Anonymous ancient author of The Life of Pythagoras, as quoted in The Pythagorean Sourcebook and Library : An Anthology of Ancient Writings which Relate to Pythagoras and Pythagorean Philosophy (1919); also quoted in The Golden Chain : An Anthology of Pythagorean and Platonic Philosophy (2004) by Algis Uzdavinys, p. 4
“We can allow satellites, planets, suns, the Universe, nay whole systems of Universes to be governed by laws; but the smallest insect, we wish to be created at once by special act.”
— The Origin of Species, Charles Darwin (1859)
“It is because the cosmos is meaningless that we must secure our individual illusions of values, direction, and interest by upholding the artificial streams which give us such worlds of salutary illusion. That is — since nothing means anything in itself, we must preserve the proximate and arbitrary background which makes things around us seem as if they did mean something.”
— H. P. Lovecraft, in a letter to James F. Morton (6 November 1930), in Selected Letters III, 1929-1931 edited by August Derleth and Donald Wandrei, p. 208
“Whatever is inconsistent with the facts must be discarded or revised. We must understand the Cosmos as it is and not confuse how it is with how we wish it to be.”
— Carl Sagan, in Cosmos (1980), p. 333
“Of the cosmic Gods some make the world be, others animate it, others harmonize it, consisting as it does of different elements; the fourth class keep it when harmonized.”
— Sallustius, in On the Gods and the Cosmos (c. 360), VI. On Gods Cosmic and Hypercosmic.
“This is the goal of all living, that the cosmos may be known, and admired, and that it may be crowned with further beauties. Nowhere and at no time, so far as we can tell, at least within our own galaxy, has the adventure reached further than in ourselves. And in us, what has been achieved is but a minute beginning. But it is a real beginning.”
— Olaf Stapledon, in Last and First Men (1930), XV. The Last Men
