  2. Common Gateway Interface - Wikipedia

    en.wikipedia.org/wiki/Common_Gateway_Interface

    Common Gateway Interface. In computing, Common Gateway Interface ( CGI) is an interface specification that enables web servers to execute an external program to process HTTP or HTTPS user requests. Such programs are often written in a scripting language and are commonly referred to as CGI scripts, but they may include compiled programs.

  3. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java ...

  4. E (programming language) - Wikipedia

    en.wikipedia.org/wiki/E_(programming_language)

    E (programming language) E is an object-oriented programming language for secure distributed computing, created by Mark S. Miller, [1] Dan Bornstein, Douglas Crockford, [2] Chip Morningstar [3] and others at Electric Communities in 1997. E is mainly descended from the concurrent language Joule and from Original-E, a set of extensions to Java ...

  5. Forward–backward algorithm - Wikipedia

    en.wikipedia.org/wiki/Forward–backward_algorithm

    Forward–backward algorithm. The forward–backward algorithm is an inference algorithm for hidden Markov models which computes the posterior marginals of all hidden state variables given a sequence of observations/emissions , i.e. it computes, for all hidden state variables , the distribution . This inference task is usually called smoothing.

  6. Reentrancy (computing) - Wikipedia

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

    Reentrancy is a programming concept where a function or subroutine can be interrupted and then resumed before it finishes executing. This means that the function can be called again before it completes its previous execution. Reentrant code is designed to be safe and predictable when multiple instances of the same function are called ...

  7. Closure (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Closure_(computer_programming)

    In programming languages, a closure, also lexical closure or function closure, is a technique for implementing lexically scoped name binding in a language with first-class functions. Operationally, a closure is a record storing a function [a] together with an environment. [1] The environment is a mapping associating each free variable of the ...

    Screenshot of a sample Bash session in GNOME Terminal 3, Fedora 15 Screenshot of Windows PowerShell 1.0, running on Windows Vista. A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command-lines.

  9. Communicating sequential processes - Wikipedia

    en.wikipedia.org/wiki/Communicating_sequential...

    Communicating sequential processes. In computer science, communicating sequential processes ( CSP) is a formal language for describing patterns of interaction in concurrent systems. [ 1] It is a member of the family of mathematical theories of concurrency known as process algebras, or process calculi, based on message passing via channels.
