WikiScanner
WikiScanner (also known as Wikipedia Scanner) was a publicly searchable database that linked anonymous edits on Wikipedia to the organizations where those edits apparently originated. It did this by cross-referencing the edits with data on the owners of the associated block of IP addresses, though it did not investigate edits made under a username. It was created by Virgil Griffith and released on August 13, 2007. In his "WikiScanner FAQ" Griffith stated his belief that WikiScanner could help make Wikipedia more reliable for controversial topics. He also indicated that he had never been employed by the Wikimedia Foundation and claimed his work on WikiScanner was "100% noncommercial". On December 21, 2012, a research group from released an open-source clone of WikiScanner called ''WikiWatchdog''. By April 2013, attempts to run "WikiScanner Classic" from wikiscanner.virgil.gr returned to the WikiScanner home page, which identified itself as "WIKIWATCHER.COM"; and invoking "WikiS ...

Scanner (radio)
A scanner (also referred to as a radio scanner) is a radio receiver that can automatically tune, or ''scan'', two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases. The term ''scanner'' generally refers to a communications receiver that is primarily intended for monitoring VHF and UHF landmobile radio systems, as opposed to, for instance, a receiver used to monitor international shortwave transmissions. More often than not, these scanners can also tune to different types of modulation as well ( AM, FM, WFM, etc.). Early scanners were slow, bulky, and expensive. Today, modern microprocessors have enabled scanners to store thousands of channels and monitor hundreds of channels per second. Recent models can follow trunked radio systems and decode APCO-P25 digital transmissions. Both hand held and desktop models are available. Scanners are often used to monitor police, ...

Lexical Analysis
In computer science, lexical analysis, lexing or tokenization is the process of converting a sequence of characters (such as in a computer program or web page) into a sequence of ''lexical tokens'' (strings with an assigned and thus identified meaning). A program that performs lexical analysis may be termed a ''lexer'', ''tokenizer'', or ''scanner'', although ''scanner'' is also a term for the first stage of a lexer. A lexer is generally combined with a parser, which together analyze the syntax of programming languages, web pages, and so forth. Applications A lexer forms the first phase of a compiler frontend in modern processing. Analysis generally occurs in one pass. In older languages such as ALGOL, the initial stage was instead line reconstruction, which performed unstropping and removed whitespace and comments (and had scannerless parsers, with no separate lexer). These steps are now done as part of the lexer. Lexers and parsers are most often used for compilers, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scanners
''Scanners'' is a 1981 Canadian science fiction horror film written and directed by David Cronenberg and starring Stephen Lack, Jennifer O'Neill, Michael Ironside, and Patrick McGoohan. In the film, "scanners" are psychics with unusual telepathic and telekinetic powers. ConSec, a purveyor of weaponry and security systems, searches out scanners to use them for its own purposes. The film's plot concerns the attempt by Darryl Revok (Ironside), a renegade scanner, to wage a war against ConSec. Another scanner, Cameron Vale (Lack), is dispatched by ConSec to stop Revok. ''Scanners'' premiered in January 1981 to lukewarm reviews from critics but became one of the first films produced in Canada to successfully compete with American films at the international box office. It brought Cronenberg and his controversial style of body horror attention from mainstream film audiences for the first time and has since been reevaluated as a cult classic. It is particularly well known for a scene that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scanner (Half-Life)
The Combine ( ) is a fictional multiverse, multidimensional empire which serves as the primary antagonistic force in the 2004 video game ''Half-Life 2'', and the subsequent episodes developed by Valve Corporation, Valve. The Combine consist of organic, synthetic, and heavily mechanized elements. They are encountered throughout ''Half-Life 2'' and its Episodic game, episodic sequels, as well as ''Half-Life: Alyx'', as hostile non-player characters as the player progresses through the games in an effort to overthrow the Combine occupation of Earth. The Combine are frequently shown as cruel rulers over the citizens of Earth, suppressing dissent with brutality, policing using violence and/or using invasive surgery to transform humans into slaves. Throughout the games, the player primarily battles transformed humans as well as synthetic and mechanical enemies that are the product of Combine technology. In addition to their role within the ''Half-Life'' series, the Combine have been ada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
