  2. TLA+ - Wikipedia

    en.wikipedia.org/wiki/TLA+

    For example, the TLA + function Double[x \in Nat] == x*2 is an element of the set [Nat -> Nat] so Double \in [Nat -> Nat] is a true statement in TLA +. Functions are also defined with [x \in S |-> e] for some expression e, or by modifying an existing function [f EXCEPT ![v 1] = v 2]. Records are a type of function in TLA +.

  3. Timeout (computing) - Wikipedia

    en.wikipedia.org/wiki/Timeout_(computing)

    Specific examples include: In the Microsoft Windows and ReactOS [2] command-line interfaces, the timeout command pauses the command processor for the specified number of seconds. [3] [4] In POP connections, the server will usually close a client connection after a certain period of inactivity (the timeout period). This ensures that connections ...

  4. Multiple dispatch - Wikipedia

    en.wikipedia.org/wiki/Multiple_dispatch

    Multiple dispatch or multimethods is a feature of some programming languages in which a function or method can be dynamically dispatched based on the run-time (dynamic) type or, in the more general case, some other attribute of more than one of its arguments. [1]

  5. Child process - Wikipedia

    en.wikipedia.org/wiki/Child_process

    This technique pertains to multitasking operating systems, and is sometimes called a subprocess or traditionally a subtask. There are two major procedures for creating a child process: the fork system call (preferred in Unix-like systems and the POSIX standard) and the spawn (preferred in the modern (NT) kernel of Microsoft Windows , as well as ...

  6. Inter-process communication - Wikipedia

    en.wikipedia.org/wiki/Inter-process_communication

    A grid computing system that connects many personal computers over the Internet via inter-process network communication. In computer science, interprocess communication (IPC) is the sharing of data between running processes in a computer system.

  7. Piggybacking (data transmission) - Wikipedia

    en.wikipedia.org/wiki/Piggybacking_(data...

    This can be solved by enabling a counter (receiver timeout) when a data frame is received. If the count ends and there is no data frame to send, the receiver will send an ACK control frame. The sender also adds a counter (emitter timeout). If the counter ends without receiving confirmation, the sender assumes packet loss, and sends the frame ...

  8. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})

  9. HTTP persistent connection - Wikipedia

    en.wikipedia.org/wiki/HTTP_persistent_connection

    However, the default connection timeout of Apache httpd 1.3 and 2.0 is as little as 15 seconds [6] [7] and just 5 seconds for Apache httpd 2.2 and above. [8] [9] The advantage of a short timeout is the ability to deliver multiple components of a web page quickly while not consuming resources to run multiple server processes or threads for too ...
