Adaptive Communication Environment
The Adaptive Communication Environment (ACE) is an open source software framework used for network programming. It provides a set of object-oriented C++ classes designed to help address the inherent complexities and challenges in network programming by preventing common errors. History ACE was initially developed by Douglas C. Schmidt during his graduate work at the University of California, Irvine. Development followed him to the Washington University in St. Louis, where he was employed. ACE is open-source software released by WU's Distributed Object Computer (DOC) group. Its development continued in the Institute for Software Integrated Systems (ISIS) at Vanderbilt University. Features ACE provides a standardized usage for operating system/machine specific features. It provides common data types and methods to access the powerful but complex features of modern operating systems. These include: inter-process communication, thread management, efficient memory management, etc. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts an ...

OpenVMS
OpenVMS, often referred to as just VMS, is a multi-user, multiprocessing and virtual memory-based operating system. It is designed to support time-sharing, batch processing, transaction processing and workstation applications. Customers using OpenVMS include banks and financial services, hospitals and healthcare, telecommunications operators, network information services, and industrial manufacturers. During the 1990s and 2000s, there were approximately half a million VMS systems in operation worldwide. It was first announced by Digital Equipment Corporation (DEC) as VAX/VMS (''Virtual Address eXtension/Virtual Memory System'') alongside the VAX-11/780 minicomputer in 1977. OpenVMS has subsequently been ported to run on DEC Alpha systems, the Itanium-based HPE Integrity Servers, and select x86-64 hardware and hypervisors. Since 2014, OpenVMS is developed and supported by VMS Software Inc. (VSI). OpenVMS offers high availability through clustering — the ability to distribute the ...

Application Programming Interfaces
An application programming interface (API) is a way for two or more computer programs to communicate with each other. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an ''API specification''. A computer system that meets this standard is said to ''implement'' or ''expose'' an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into the software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to ''call'' that ...

Cross-platform Support Middleware
A cross-platform support middleware (CPSM) is a software abstraction layer that guarantees the existence, and correct implementation, of a set of services on top a set of platforms. Abstraction method The abstraction method in the CPSM development is the method used to compile the concrete source code for a given platform without compromising the abstract interfaces provided. The most commonly used abstraction methods in CPSM development are: conditional compilation and directory separation of sources. The first method consists in embedding preprocessor instructions in the source code to conditionally select the source subtree compatible with a given platform. The second method takes advantage of the filesystem organization to divide the source code in different folders, one for each incompatible platform. Thus delegating the selection problem to the build system. Some distributions like MSYS and Cygwin may help build the cross-platform code in a Unix-like environment e ...

CORBA
The Common Object Request Broker Architecture (CORBA) is a standard defined by the Object Management Group (OMG) designed to facilitate the communication of systems that are deployed on diverse platforms. CORBA enables collaboration between systems on different operating systems, programming languages, and computing hardware. CORBA uses an object-oriented model although the systems that use the CORBA do not have to be object-oriented. CORBA is an example of the distributed object paradigm. Overview CORBA enables communication between software written in different languages and running on different computers. Implementation details from specific operating systems, programming languages, and hardware platforms are all removed from the responsibility of developers who use CORBA. CORBA normalizes the method-call semantics between application objects residing either in the same address-space (application) or in remote address-spaces (same host, or remote host on a network).

Communication Software
Communication software is used to provide remote access to systems and exchange files and messages in text, audio and/or video formats between different computers or users. This includes terminal emulators, file transfer programs, chat and instant messaging programs, as well as similar functionality integrated within MUDs. The term is also applied to software operating a bulletin board system, but seldom to that operating a computer network or Stored Program Control exchange. History E-mail was introduced in the early 1960's as a way for multiple users of a time-sharing mainframe computer to communicate. Basic text chat functionality has existed on multi-user computer systems and bulletin board systems since the early 1970s. In the 1980s, a terminal emulator was a piece of software necessary to log into mainframes and thus access e-mail. Prior to the rise of the Internet, computer files were exchanged over dialup lines, requiring ways to send binary files over communication syste ...

Software Design Pattern
In software engineering, a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. Rather, it is a description or template for how to solve a problem that can be used in many different situations. Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved. Patterns that imply mutable state may be unsuited for functional programming languages. Some patterns can be rendered unnecessary in languages that have built-in support for solving the problem they are trying to solve, and object-oriented patterns are not necessarily suitable for non-object-oriented langua ...

Boeing Wedgetail
The Boeing 737 AEW&C is a twin-engine airborne early warning and control aircraft based on the Boeing 737 Next Generation design. It is lighter than the 707-based Boeing E-3 Sentry, and has a fixed, active electronically scanned array radar antenna instead of a rotating one. It was designed for the Royal Australian Air Force (RAAF) under "Project Wedgetail" and designated E-7A Wedgetail. The 737 AEW&C has also been selected by the Turkish Air Force (under "Project Peace Eagle", Turkish: ''Barış Kartalı'', designated ''E-7T'', the Republic of Korea Air Force ("Project Peace Eye", Korean: "피스 아이"), and the United Kingdom (designated Wedgetail AEW1). In April 2022, the United States Air Force announced that the AEW&C will be replacing the E-3 beginning in 2027. Design and development The Australian Department of Defence evaluated industry proposals for airborne surveillance and early warning systems as early as 1986. Further studies led to the approval of the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iridium (satellite)
The Iridium satellite constellation provides L band voice and data information coverage to satellite phones, pagers and integrated transceivers over the entire surface of Earth. Iridium Communications owns and operates the constellation, additionally selling equipment and access to its services. It was conceived by Bary Bertiger, Raymond J. Leopold and Ken Peterson in late 1987 (in 1988 protected by patents Motorola filed in their names) and then developed by Motorola on a fixed-price contract from July 29, 1993, to November 1, 1998, when the system became operational and commercially available. The constellation consists of 66 active satellites in orbit, required for global coverage, and additional spare satellites to serve in case of failure. Satellites are placed in low Earth orbit at a height of approximately and inclination of 86.4°. The nearly polar orbit and communication between satellites via Ka band inter-satellite links provide global service availability (includin ...
