ICBM Address
ICBM (intercontinental ballistic missile) address or missile address is hacker slang for one's longitude and latitude (preferably to seconds-of-arc accuracy) when placed in a signature or another publicly available file. Origin The form that used to register a site with the Usenet mapping project, before Internet connectivity became commonplace for Usenet sites, included a field for longitude and latitude, preferably to seconds-of-arc accuracy. This was actually used for generating geographically-correct maps of Usenet links on a plotter; however, it became traditional to refer to this as one's ICBM address or missile address, and some people include it in their sig block with that name. A typical tag might read "ICBM Address: 36.8274040 N, 108.0204086 W". Modern use Today, using the ICBM method of coordinates is one method of geotagging webpages or other online material. Some projects parse ICBM address included in webpages via meta tags, which can then be used to map o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trident C4 First Launch
A trident is a three- pronged spear. It is used for spear fishing and historically as a polearm. The trident is the weapon of Poseidon, or Neptune, the God of the Sea in classical mythology. The trident may occasionally be held by other marine divinities such as Tritons in classical art. Tridents are also depicted in medieval heraldry, sometimes held by a merman-Triton. In Hinduism, it is the weapon of Shiva, known as '' trishula'' (Sanskrit for "triple-spear"). Etymology The word "trident" comes from the French word ''trident'', which in turn comes from the Latin word ' or ': ''tri'' meaning "three" and ''dentes'' meaning "teeth", referring specifically to the three prongs, or "teeth", of the weapo The Greek language, Greek equivalent is (''tríaina''), from Proto-Greek ''trianja'', meaning "threefold". The Greek term does not imply three of anything specific, and is vague about the shape, thus the assumption it was originally of "trident" form has been challenge ...

Meta Tags
Meta elements are tags used in HTML and XHTML documents to provide structured metadata about a Web page. They are part of a web page's head section. Multiple Meta elements with different attributes can be used on the same page. Meta elements can be used to specify page description, keywords and any other metadata not provided through the other head elements and attributes. The meta element has two uses: either to emulate the use of an HTTP response header field, or to embed additional metadata within the HTML document. With HTML up to and including HTML 4.01 and XHTML, there were four valid attributes: content, http-equiv, name and scheme. Under HTML 5, charset has been added and scheme has been removed. http-equiv is used to emulate an HTTP header, and name to embed metadata. The value of the statement, in either case, is contained in the content attribute, which is the only required attribute unless charset is given. charset is used to indicate the character set of the document ...

Intercontinental Ballistic Missiles
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Slang
Internet slang (also called Internet shorthand, cyber-slang, netspeak, digispeak or chatspeak) is a non-standard or unofficial form of language used by people on the Internet to communicate to one another. An example of Internet slang is "LOL" meaning "laugh out loud". Since Internet slang is constantly changing, it is difficult to provide a standardized definition.Yin Yan (2006) World Wide Web and the Formation of the Chinese and English "Internet Slang Union". Computer-Assisted Foreign Language Education. Vol. 1. However, it can be understood to be any type of slang that Internet users have popularized, and in many cases, have coined. Such terms often originate with the purpose of saving keystrokes or to compensate for small character limits. Many people use the same abbreviations in texting, instant messaging, and social networking websites. Acronyms, keyboard symbols, and abbreviations are common types of Internet slang. New dialects of slang, such as leet or Lolspeak, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geotagging
Geotagging, or GeoTagging, is the process of adding geographical identification metadata to various media such as a geotagged photograph or video, websites, SMS messages, QR Codes or RSS feeds and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though they can also include altitude, bearing, distance, accuracy data, and place names, and perhaps a time stamp. Geotagging can help users find a wide variety of location-specific information from a device. For instance, someone can find images taken near a given location by entering latitude and longitude coordinates into a suitable image search engine. Geotagging-enabled information services can also potentially be used to find location-based news, websites, or other resources. Geotagging can tell users the location of the content of a given picture or other media or the point of view, and conversely on some media platforms show media relevant to a given location.

Geo (microformat)
Geo is a microformat used for marking up WGS84 geographical coordinates (latitude;longitude) in (X)HTML. Although termed a "draft" specification, this is a formality, and the format is stable and in widespread use; not least as a sub-set of the published hCalendar and hCard microformat specifications, neither of which is still a draft. Use of Geo allows parsing tools (for example other websites, or Firefox's Operator extension) to extract the locations, and display them using some other website or mapping tool, or to load them into a GPS device, index or aggregate them, or convert them into an alternative format. Usage *If latitude is present, so must be longitude, and vice versa. *The same number of decimal places should be used in each value, including trailing zeroes.''Must'' and ''should'' are used per the IETF document The Geo microformat is applied using three HTML classes. For example, the marked-up text: Belvide: 52.686; -2.193 becomes: Belvide: ; by addin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LOC Record
In the Domain Name System, a LOC record (experimental ) is a means for expressing geographic location information for a domain name. It contains WGS84 Latitude, Longitude and Altitude (ellipsoidal height) information together with host/subnet physical size and location accuracy. This information can be queried by other computers connected to the Internet. Record format The LOC record is expressed in a master file in the following format: LOC ( d1 1.html"_;"title="1_[s1">1_[s1__d2_[m2_[s2 _____________________________alt["m".html" ;"title="1">1_[s1__d2_[m2_[s2.html" ;"title="1.html" ;"title="1 [s1">1 [s1 d2 [m2 [s2">1.html" ;"title="1 [s1">1 [s1 d2 [m2 [s2 alt["m"">1">1_[s1__d2_[m2_[s2.html" ;"title="1.html" ;"title="1 [s1">1 [s1 d2 [m2 [s2">1.html" ;"title="1 [s1">1 [s1 d2 [m2 [s2 alt["m"[siz["m"] [hp["m"] [vp["m" ) (The parentheses are used for multi-line data as specified in RF ...

Geographic Coordinate System
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

Schema
The word schema comes from the Greek word ('), which means ''shape'', or more generally, ''plan''. The plural is ('). In English, both ''schemas'' and ''schemata'' are used as plural forms. Schema may refer to: Science and technology * SCHEMA (bioinformatics), an algorithm used in protein engineering * Schema (genetic algorithms), a set of programs or bit strings that have some genotypic similarity * Schema.org, a web markup vocabulary * Schema (logic) ** Axiom schema, in formal logic * Image schema, a recurring pattern of spatial sensory experience * Database schema * XML schema Other * Body schema, a neural representation of one's own bodily posture * Galant Schemata, stock phrases in Galant music * Schema (Kant), in philosophy * Schema (psychology), a mental set or representation * Schema Records, a jazz record label in Milan, Italy *, a solemn vow of asceticism of a monk in Orthodox monasticism ** Great Schema, the highest degree of Orthodox monasticism * ''Schema'' (fly) ...

Geo URI Scheme
The geo URI scheme is a Uniform Resource Identifier (URI) scheme defined by the Internet Engineering Task Force's RFC 5870 (published 8 June 2010) as: a Uniform Resource Identifier (URI) for geographic locations using the 'geo' scheme name. A 'geo' URI identifies a physical location in a two- or three-dimensional coordinate reference system in a compact, simple, human-readable, and protocol-independent way. The current revision of the vCard specification supports geo URIs in a vCard's "GEO" property, and the GeoSMS standard uses geo URIs for geotagging SMS messages. Android based devices support geo URIs, although that implementation is based on a draft revision of the specification, and supports a different set of URI parameters and query strings. A geo URI is not to be confused with the former website of ''GeoURL'' (which had implemented ICBM addresses). Example A simple geo URI might look like: :geo:37.786971,-122.399677 where the two numerical values represent latitu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Database
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an appli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
