Distributed Data Management Architecture (DDM) is IBM's open, published software architecture for creating, managing and accessing data on a remote computer. DDM was initially designed to support record-oriented files; it was extended to support hierarchical directories, stream-oriented files, queues, and system command processing; it was further extended to be the base of IBM's Distributed ...
Data diffusion machine (DDM) is a historical virtual shared memory architecture where data is free to migrate through the machine. Shared memory machines are convenient for programming but do not scale beyond tens of processors. The DDM overcomes this problem by providing a virtual memory abstraction on top of a distributed memory machine. A ...
With DDM (Dynamic Device Mapping) Technology, the communication between shared peripherals and all connected systems are maintained 100% of the time, even as a user switches between the KVM ports. This makes generic device emulation unnecessary as the DDM allows each connected computer system to believe all connected I/O devices are remaining ...
A program running on a web server (server-side scripting) is used to generate the web content on various web pages, manage user sessions, and control workflow. Server responses may be determined by such conditions as data in a posted HTML form , parameters in the URL , the type of browser being used, the passage of time, or a database or server ...
Structure and Interpretation of Computer Programs (SICP) is a computer science textbook by Massachusetts Institute of Technology professors Harold Abelson and Gerald Jay Sussman with Julie Sussman. It is known as the "Wizard Book" in hacker culture . [ 1 ]
JSX (JavaScript XML, formally JavaScript Syntax eXtension) is an XML-like extension to the JavaScript language syntax. [1] Initially created by Facebook for use with React , JSX has been adopted by multiple web frameworks .
In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
The program generated a unique serial number which then called the author's BBS via a dialup modem connection. Upon connection, the serial number was validated. A unique "key" was returned which allowed the program to continue for a trial period. If two D'Bridge systems communicated using the same key, the software deliberately crashed.
