Profanity Filter
A wordfilter (sometimes referred to as just "filter" or "censor") is a script typically used on Internet forums or chat rooms that automatically scans users' posts or comments as they are submitted and automatically changes or censors particular words or phrases. The most basic wordfilters search only for specific strings of letters, and remove or overwrite them regardless of their context. More advanced wordfilters make some exceptions for context (such as filtering "butt" but not "butter"), and the most advanced wordfilters may use regular expressions. Functions Wordfilters can serve any of a number of functions. Removal of vulgar language A ''swear filter'', also known as a ''profanity filter'' or ''language filter'' is a software subsystem which modifies text to remove words deemed offensive by the administrator or community of an online forum. Swear filters are common in custom-programmed chat rooms and online video games, primarily MMORPGs. This is not to be confused with ...

Whitespace Character
A whitespace character is a character data element that represents white space when text is rendered for display by a computer. For example, a ''space'' character (, ASCII 32) represents blank space such as a word divider in a Western script. A printable character results in output when rendered, but a whitespace character does not. Instead, whitespace characters define the layout of text to a limited degree, interrupting the normal sequence of rendering characters next to each other. The output of subsequent characters is typically shifted to the right (or to the left for right-to-left script) or to the start of the next line. The effect of multiple sequential whitespace characters is cumulative such that the next printable character is rendered at a location based on the accumulated effect of preceding whitespace characters. The origin of the term ''whitespace'' is rooted in the common practice of rendering text on white paper. Normally, a whitespace character is ''not' ...

Soft Hyphen
In computing and typesetting, a soft hyphen (Unicode ) or syllable hyphen, is a code point reserved in some coded character sets for the purpose of breaking words across lines by inserting visible hyphens if they fall on the line end but remain invisible within the line. Two alternative ways of using the soft hyphen character for this purpose have emerged, depending on whether the encoded text will be broken into lines by its recipient, or has already been preformatted by its originator. Text to be formatted by the recipient The use of SHY characters in text that will be broken into lines by the recipient is the application context considered by the post-1999 HTML and Unicode specifications, as well as some word-processing file formats. In this context, the soft hyphen may also be called a discretionary hyphen or optional hyphen. It serves as an invisible marker used to specify a place in text where a hyphenated break is allowed without forcing a line break in an inconvenient ...

IDN Homograph Attack
The internationalized domain name (IDN) homograph attack (sometimes written as homoglyph attack) is a method used by malicious parties to deceive computer users about what remote system they are communicating with, by exploiting the fact that many different characters look alike (i.e., they rely on homoglyphs to deceive visitors). For example, the Cyrillic script, Cyrillic, Greek alphabet, Greek and Latin script, Latin alphabets each have a letter that has the same shape but represents different sounds or phonemes in their respective writing systems. This kind of spoofing attack is also known as script spoofing. Unicode incorporates numerous scripts (writing systems), and, for a number of reasons, similar-looking characters such as , Greek Ο, , Latin O, and , Cyrillic О were not assigned the same code. Their incorrect or malicious usage is a possibility for security attacks. Thus, for example, a regular user of may be lured to click on it unquestioningly as an apparently famil ...

Cyrillic Script
The Cyrillic script ( ) is a writing system used for various languages across Eurasia. It is the designated national script in various Slavic languages, Slavic, Turkic languages, Turkic, Mongolic languages, Mongolic, Uralic languages, Uralic, Caucasian languages, Caucasian and Iranian languages, Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia, and East Asia, and used by many other minority languages. , around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union on 1 January 2007, Cyrillic became the third official script of the Languages of the European Union#Writing systems, European Union, following the Latin script, Latin and Greek alphabet, Greek alphabets. The Early Cyrillic alphabet was developed during the 9th century AD at the Preslav Literary School in the First Bulga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leet
Leet (or "1337"), also known as eleet or leetspeak, or simply hacker speech, is a system of modified spellings used primarily on the Internet. It often uses character replacements in ways that play on the similarity of their glyphs via reflection or other resemblance. Additionally, it modifies certain words on the basis of a system of suffixes and alternative meanings. There are many dialects or linguistic varieties in different online communities. The term "leet" is derived from the word '' elite'', used as an adjective to describe skill or accomplishment, especially in the fields of online gaming and computer hacking. The leet lexicon includes spellings of the word as ''1337'' or ''leet''. History Leet originated within bulletin board systems (BBS) in the 1980s,Mitchell.An Explanation of l33t Speak. where having "elite" status on a BBS allowed a user access to file folders, games, and special chat rooms. The Cult of the Dead Cow hacker collective has been credited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Character (computing)
In computing and telecommunications, a character is the internal representation of a character (symbol) used within a computer or system. Examples of characters include letters, numerical digits, punctuation marks (such as "." or "-"), and whitespace. The concept also includes control characters, which do not correspond to visible symbols but rather to instructions to format or process the text. Examples of control characters include carriage return and tab as well as other instructions to printers or other devices that display or otherwise process text. Characters are typically combined into '' strings''. Historically, the term ''character'' was used to denote a specific number of contiguous bits. While a character is most commonly assumed to refer to 8 bits (one byte) today, other options like the 6-bit character code were once popular, and the 5-bit Baudot code has been used in the past as well. The term has even been applied to 4 bits with only 16 possible valu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASCII Art
ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) character (computing), characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII). The term is also loosely used to refer to #Other text-based visual art, text-based visual art in general. ASCII art can be created with any text editor, and is often used with free-form languages. Most examples of ASCII art require a Monospaced font, fixed-width font (non-proportional typeface, fonts, as on a traditional typewriter) such as Courier (typeface), Courier or Consolas for presentation. Among the oldest known examples of ASCII art are the creations by computer-art pioneer Kenneth Knowlton from around 1966, who was working for Bell Labs at the time.

Imageboard
An imageboard is a type of Internet forum that focuses on the posting of images, often alongside text and discussion. The first imageboards were created in Japan as an extension of the textboard concept. These sites later inspired the creation of a number of English-language imageboards. Characteristics Imageboards, similar to bulletin board systems, are used for discussions of a variety of topics. The primary focus of imageboards, however, is directed away from text posts, and is instead placed on picture posts. The two share many of the same structures, including separate forums for separate topics, as well as similar audiences. Imageboards are much more transitory with content—on some boards (especially highly trafficked ones), the thread deletion time can be as little as 10 minutes. The most popular English language imageboard, 4chan, similarly has a large variety of topics. Imageboards are also different from online galleries in that most of the works posted are not mad ...

Textboard
A textboard is a simple kind of Internet forum; most textboards require neither registration nor entry of a screen name. Textboards, like imageboards, were invented in Japan, but they remain relatively unknown outside it, in contrast to imageboards (such as 4chan). Features One of the key differences between textboards and traditional forums is that textboards allow users to post without registration, and often encourage anonymous discussion. Hiroyuki Nishimura, the founder of 2channel, says that the philosophy behind anonymous posting is that "all information is treated equally; only an accurate argument will work". Many textboards support a form of pseudo-registration by allowing users to use tripcodes, although users tend to post anonymously. Textboards tend to be much simpler than traditional forums. While forums software such as phpBB or vBulletin supports image or other media embedding, private messaging, polls, and various other features, textboards allow only the ...

Spam (electronic)
Spamming is the use of messaging systems to send multiple unsolicited messages (spam) to large numbers of recipients for the purpose of commercial advertising, non-commercial proselytizing, or any prohibited purpose (especially phishing), or simply repeatedly sending the same message to the same user. While the most widely recognized form of spam is email spam, the term is applied to similar abuses in other media: messaging spam, instant messaging spam, Newsgroup spam, Usenet newsgroup spam, spamdexing, Web search engine spam, spam in blogs, wiki spam, classified advertising, online classified ads spam, mobile phone spam, mobile phone messaging spam, Forum spam, Internet forum spam, junk fax, junk fax transmissions, social spam, spam mobile apps, television advertising and file sharing spam. It is named after Spam (food), Spam, a luncheon meat, by way of a Spam (Monty Python sketch), Monty Python sketch about a restaurant that has Spam in almost every dish in which Vikings annoyi ...
