Portable Distributed Objects
Portable Distributed Objects (PDO) is an application programming interface (API) for creating object-oriented code that can be executed remotely on a computer network, network of computers. It was created by NeXT Computer, Inc. using their OpenStep system, whose use of Objective-C made the package very easy to write. It was characterized by its very light weight and high speed in comparison to similar systems such as CORBA. Versions of PDO were available for Solaris (operating system), Solaris, HP-UX and all versions of the OPENSTEP system, although an agreement was also announced for a version to be made for Digital Unix, then still known as OSF/1, with delivery anticipated after versions for SunOS and Solaris had been released. Product licence pricing for these platforms varied from $2,500 for use on a "small server" up to $10,000 for use on a "large server". A version that worked with Microsoft Object Linking and Embedding, OLE was also available called ''D'OLE'', allowing distri ...

Application Programming Interface
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 ...

MacOS APIs
macOS (; previously OS X and originally Mac OS X) is a Unix operating system developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac (computer), Mac computers. Within the market of desktop and laptop computers it is the Usage share of operating systems#Desktop and laptop computers, second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. macOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT Computer, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. All releases from Mac OS X Leopard, Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X Lion, OS X 10. ...

Apple Computer
Apple Inc. is an American multinational technology company headquartered in Cupertino, California, United States. Apple is the largest technology company by revenue (totaling in 2021) and, as of June 2022, is the world's biggest company by market capitalization, the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet, Amazon, Meta, and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977 and the company's next computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user interfaces, in ...

Cocoa (API)
Cocoa is Apple's native object-oriented application programming interface (API) for its desktop operating system macOS. Cocoa consists of the Foundation Kit, Application Kit, and Core Data frameworks, as included by the Cocoa.h header file, and the libraries and frameworks included by those, such as the C standard library and the Objective-C runtime.Mac Technology Overview: OS X Frameworks Developer.apple.com.

GNUstep
GNUstep is a free software implementation of the Cocoa (formerly OpenStep) Objective-C frameworks, widget toolkit, and application development tools for Unix-like operating systems and Microsoft Windows. It is part of the GNU Project. GNUstep features a cross-platform, object-oriented IDE. Apart from the default Objective-C interface, GNUstep also has bindings for Java, Ruby, GNU Guile and Scheme. The GNUstep developers track some additions to Apple's Cocoa to remain compatible. The roots of the GNUstep application interface are the same as the roots of Cocoa: NeXTSTEP and OpenStep. GNUstep thus predates Cocoa, which emerged when Apple acquired NeXT's technology and incorporated it into the development of the original Mac OS X, while GNUstep was initially an effort by GNU developers to replicate the technically ambitious NeXTSTEP's programmer-friendly features. History GNUstep began when Paul Kunz and others at Stanford Linear Accelerator Center wanted to port HippoDraw f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WebObjects
WebObjects was a Java web application server and a server-based web application framework originally developed by NeXT Software, Inc. WebObject's hallmark features are its object-orientation, database connectivity, and prototyping tools. Applications created with WebObjects can be deployed as web sites, Java WebStart desktop applications, and/or standards-based web services. The deployment runtime is pure Java, allowing developers to deploy WebObjects applications on platforms that support Java. One can use the included WebObjects Java SE application server or deploy on third-party Java EE application servers such as JBoss, Apache Tomcat, WebLogic Server or IBM WebSphere. WebObjects was maintained by Apple for quite a while. However, because Apple has stopped maintaining the software, it now is instead maintained by an online community of volunteers. This community calls it "Project Wonder". WebObjects now also has a few competitors: see below. History NeXT creates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strong Typing
In computer programming, one of the many ways that programming languages are colloquially classified is whether the language's type system makes it strongly typed or weakly typed (loosely typed). However, there is no precise technical definition of what the terms mean and different authors disagree about the implied meaning of the terms and the relative rankings of the "strength" of the type systems of mainstream programming languages. For this reason, writers who wish to write unambiguously about type systems often eschew the terms "strong typing" and "weak typing" in favor of specific expressions such as "type safety". Generally, a strongly typed language has stricter typing rules at compile time, which implies that errors and exceptions are more likely to happen during compilation. Most of these rules affect variable assignment, function return values, procedure arguments and function calling. Dynamically typed languages (where type checking happens at run time) can also be stro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Run Time System
In computer programming, a runtime system or runtime environment is a sub-system that exists both in the computer where a program is created, as well as in the computers where the program is intended to be run. The name comes from the compile time and runtime division from compiled languages, which similarly distinguishes the computer processes involved in the creation of a program (compilation) and its execution in the target machine (the run time). Most programming languages have some form of runtime system that provides an environment in which programs run. This environment may address a number of issues including the management of application memory, how the program accesses variables, mechanisms for passing parameters between procedures, interfacing with the operating system, and otherwise. The compiler makes assumptions depending on the specific runtime system to generate correct code. Typically the runtime system will have some responsibility for setting up and managing ...

Distributed Objects Everywhere
Distributed Objects Everywhere (DOE) was a long-running Sun Microsystems project to build a distributed computing environment based on the CORBA system in the 'back end' and OpenStep as the user interface. First started in 1990 and announced soon thereafter, it remained vaporware for many years before it was finally released as NEO in 1995. It was sold for only a short period before being dropped (along with OpenStep) in 1996. In its place is what is today known as Enterprise JavaBeans. Background In the early 1990s the 'next big thing' in computing was to use desktop microcomputers to display and edit data being provided by Mainframe computer, mainframes and minicomputers. Although a number of methods for this sort of access already existed, the division of labor was not at all even. For instance, SQL required the workstation to download huge data sets and then process them locally, whereas use of terminal emulators left all of the work to the server and provided no GUI.
