Callback (computer Programming)
In computer programming, a callback or callback function is any reference to executable code that is passed as an argument to another piece of code; that code is expected to ''call back'' (execute) the callback function as part of its job. This execution may be immediate as in a synchronous callback, or it might happen at a later point in time as in an asynchronous callback. Programming languages support callbacks in different ways, often implementing them with subroutines, lambda expressions, blocks, or function pointers. Design There are two types of callbacks, differing in how they control data flow at runtime: ''blocking callbacks'' (also known as ''synchronous callbacks'' or just ''callbacks'') and ''deferred callbacks'' (also known as ''asynchronous callbacks''). While blocking callbacks are invoked before a function returns (as in the C example below), deferred callbacks may be invoked after a function returns. Deferred callbacks are often used in the context of I/O o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callback Verification
Callback verification, also known as callout verification or Sender Address Verification, is a technique used by SMTP software in order to validate e-mail addresses. The most common target of verification is the sender address from the message envelope (the address specified during the SMTP dialogue as " MAIL FROM"). It is mostly used as an anti-spam measure. Purpose Since a large percentage of e-mail spam is generated from forged sender ("mfrom") addresses, some spam can be detected by checking whether forging resulted in an invalid address, using this method. A related technique is "call forwards", in which a secondary or firewall mail exchanger can verify recipients at the primary mail exchanger for the domain in order to decide whether the address is deliverable. Process The receiving mail server verifies the sender address, by verifying both parts of the sender address - the domain name (part after the @ character), and the local part (part before the @ character).

The Callback
"The Callback" is the second episode of the American television series '' Smash''. The episode aired on February 13, 2012. It was written by series creator Theresa Rebeck and directed by Michael Mayer, who also directed the pilot. Plot As Ivy Lynn (Megan Hilty) and Karen Cartwright (Katharine McPhee) both attempt to please Derek Wills (Jack Davenport) in order to win the role of Marilyn, Julia Houston (Debra Messing) and her husband Frank ( Brian d'Arcy James) become frustrated by the process of their international adoption and Eileen's (Anjelica Huston) acrimonious divorce complicates her attempt to finance the musical. We are shown that Karen in callbacks is very slow to pick up the dance routines, and has problems with acting (Derek tells her she isn't giving him "anything," Marilyn or otherwise). In the end, Ivy wins the role of Marilyn after impressing Derek with her eloquent and vulnerable scenework in callbacks. Derek is moved by Ivy's work to make an advance, and the two b ...

Callback (telecommunications)
In telecommunications, a callback or call-back occurs when the originator of a call is immediately called back in a second call as a response. International calling A callback, in this sense is a method of making low-cost international calls via a third country, usually the United States, where call charges are considerably lower. One variation of this technology was developed by IDT Corporation in 1991. IDT Corp used a hardware solution that was never widely accepted and ultimately failed and was surpassed by a software solution concurrently developed by Jorge Blanco at MCI Telecommunications for The United Nations Development Programme and their staff Wolfgang Scholtes and Kumar Navaratnum. In order to use a callback service, a subscriber is allocated a unique number in, for example, the US, which must first be dialled in order to trigger a return call. This is known (in the US) as a Direct Inbound Dialing (DID) number, or in the UK as a Direct Dial-In (DDI) number. Where Calle ...

Web Callback
Web callback is a technology where a person can enter his or her telephone number in a form on a web site. The company who owns that Web site will then receive the Web callback request and a call center agent will call the person who made the request back on the number they entered. In some implementations, the Web callback service provider will place outgoing calls to the owner of the web site, and the user, then connect the calls together. An alternative approach is for the web site owner to receive a SMS text message, so they can initiate the call to the web site user. Some Web callback service providers allow the callback form to be embedded into the web site, sometimes matching the look and feel of the existing site. Others simply add a hyperlink to the site, which is linked to the service providers own site. Web Callback vs Click To Call Different than a simple computer Click To Call ( CTC), Web Callbacks are not calls generated from the users computer, but will call a ...

Audition
An audition is a sample performance by an actor, singer, musician, dancer or other performer. It typically involves the performer displaying their talent through a previously memorized and rehearsed solo piece or by performing a work or piece given to the performer at the audition or shortly before. In some cases, such as with a model or acrobat, the individual may be asked to demonstrate a range of professional skills. Actors may be asked to present a monologue. Singers will perform a song in a popular music context or an aria in a Classical context. A dancer will present a routine in a specific style, such as ballet, tap dance or hip-hop, or show his or her ability to quickly learn a choreographed dance piece. The audition is a systematic process in which industry professionals select performers, which is in some ways analogous to a job interview in the regular job market. In an audition, the employer is testing the ability of the applicant to meet the needs of the job and asse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Callback (comedy)
A callback, in terms of comedy, is a joke that refers to one previously told in the set. It is also known as an internal allusion, a literary device that helps give structure to the piece of writing. Television In television, the term callback has come to mean a joke or line that refers to a previous episode (or sometimes, in rare cases, movies). Particularly in earlier sitcoms—though even until the early 1990s—callbacks were rare and often frowned upon by networks, because they threaten to alienate a viewer who is new to the series, or who has missed episodes, particularly if the callback is tied to previous episodes (this is especially a threat to a show's syndication value, as shows in which the episodes are self-contained, and thus can be rerun out of order, can fetch a higher sale price than shows that must be run in sequence). ''Seinfeld'', a show built around stand-up comedy, regularly used callbacks in its scripts; its use of the strategy commonly kept the callbacks ...
