Phantom OS
Encyclopedia
Phantom OS is an operating system
mostly made by Russian programmers.
Phantom OS is based on a concept of persistent virtual memory, and is managed-code oriented. Phantom OS is one of a few OSes that are not based on classical concepts of UNIX-like systems. Its primary goal is to achieve simplicity and effectiveness in both the operating system and applications at the same time.
Phantom lays on a principle "Anything is an object", differently from the Unix
-like approach "Anything is a file".
Global address space: Very effective and inexpensive IPC.
Single (flat) address space allows transfer of objects from one process (application) to another been done by transferring links to that object. Security is achieved through the absence of pointer arithmetic and the inability of an application to get linked to an object other than by calling a public method.
Persistence: Application code does not see OS restarts and could live forever—this makes the concept of a file obsolete and any variable or data structure could be stored forever and at the same time be available directly through a pointer. Differently from hibernation that is done in other OSs, persistence lies in the very core principles of the Phantom OS core. It is done transparently for applications; in most cases it does not require re-programming of an application. Persistence stays even if the computer crashes.
architecture is in the works works (currently being tested, transfer is not yet done) and transfer to mips
and amd64
has been started. Kernel operations have been demonstrated at the biggest Russian IT-conferences RIT 2011, ADD 2010, CC 2010, and 2009.

Basics
Managed code: Memory protection on object level, rather than on process level; absence of pointer arithmetic in managed code avoids many problems that are present in unmanaged code.Global address space: Very effective and inexpensive IPC.

x86-64 is an extension of the x86 instruction set. It supports vastly larger virtual and physical address spaces than are possible on x86, thereby allowing programmers to conveniently work with much larger data sets. x86-64 also provides 64-bit general purpose registers and numerous other...
