| | The GNU Mach Reference Manual: Introduction |
 | | GNU Mach is the microkernel of the GNU Project. | | | Mach has been used in many operating systems in the past, usually as the base for a single UNIX server. | | | The rest of this manual is a technical discussion of the Mach programming interface and its implementation, and would not be helpful until you want to learn how to extend the system or modify the kernel. |

| | Mach and Ehrenfels: Foundations of Gestalt Theory |
| | Mach, it will turn out, was unable successfully to incorporate his descriptions of complex perception within his general atomistic framework in no small part because his understanding of dependence was in a quite specific sense too narrow. | | | A first provisional formulation of Mach's account of the relation of dependence might run as follows: two variables (continuously variable quantities) are dependent if and only if the variation in one is reflected in a simultaneous variation in the other. | | | It is important not only because Mach was almost certainly the first to have addressed the problem of providing such a theory without appeal to extraneous and ambiguous or unexplained notions like that of causality. |

| | Ernst Mach - Iridis Encyclopedia |
| | Mach held that scientific laws are summaries of experimental events, constructed for the purpose of human comprehension of complex data. | | | In the area of sensory perception, he is best known for an optical illusion called the Mach band. | | | Mach's paper on this subject was published in 1877 and correctly describes the sound effects observed during the supersonic motion of a projectile. |

| | The user can also enter a velocity or a Mach number at that altitude and the calculator will compute the corresponding airspeeds. | | | The Mach number (M) is simply the ratio of the vehicle's velocity (V) divided by the speed of sound at that altitude (a). | | | For example, an aircraft flying at Mach 0.8 is traveling at 80% of the speed of sound while a missile cruising at Mach 3 is traveling at three times the speed of sound. |

| | GNU Hurd - Wikipedia, the free encyclopedia |
| | In the original Mach efforts, this sort of "set of servers" was considered to be one of the main goals of the design, but the Hurd appears to be the first Mach-based system to actually be implemented in this fashion (whereas QNX is similar but based on its own microkernel). | | | It is a set of servers (or daemons, in Unix-speak) that work on top of either the GNU Mach microkernel or the L4 microkernel; together, they form the kernel of the GNU operating system. | | | It has been under development since 1990 by the GNU Project and is distributed as free software under the GPL. |

| | MACH is designed to support computing environments consisting of networks of uniprocessors and multiprocessors. | | | To enhance performance, a memory manager may allow a MACH kernel to maintain its memory cache for a memory object after all virtual address space references to it are gone, by asserting the caching parameter to the memory_object_set_attributes call. | | | Ports of MACH to other computers are in progress. |

| | GNU Hurd definition of GNU Hurd in computing dictionary - by the Free Online Dictionary, Thesaurus and Encyclopedia. |
| | Currently there are free ports of the Mach kernel to the Intel 80386 IBM PC, the DEC PMAX workstation, the Luna 88k and several other machines, with more in progress, including the Amiga and DEC Alpha-3000 machines. | | | Porting the GNU Hurd and GNU C Library is easy (easier than porting GNU Emacs, certainly easier than porting GCC) once a Mach port to a particular platform exists. | | | Mach's virtual memory management and message-passing facilities are extensively used by the Hurd. |

| | Microkernel-based OS Efforts |
| | That makes them a bad target for a microkernel, and the primary reason why Mach and Minix are so bad - they want to emulate Unix on top of a microkernel. | | | New kinds of deadlocks and other error conditions are possible between system components that would not be possible with a monolithic kernel. | | | The microkernel architecture abstracts lower-level os facilities, implementing them in kernel space, and moves higher-level facilities to processes in user space. |
