Pinterest
Pinterest is an American image sharing and social media service designed to enable saving and discovery of information (specifically "ideas") on the internet using images, and on a smaller scale, animated GIFs and videos, in the form of pinboards. The site was created by Ben Silbermann, Paul Sciarra, and Evan Sharp, and had 433 million global monthly active users as of July 2022. It is operated by Pinterest, Inc., based in San Francisco. History The idea for ''Pinterest'' emerged from an earlier app created by Ben Silberman and Paul Sciarra called Tote which served as a virtual replacement for paper catalogs. Tote struggled as a business, significantly due to difficulties with mobile payments. At the time, mobile payment technology was not sophisticated enough to enable easy on-the-go transactions, inhibiting users from making many purchases via the app. Tote users were, however, amassing large collections of favorite items and sharing them with other users. The behavior struck ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowling Pin
Bowling pins (historically also known as skittles or kegels) are the target of the bowling ball in various bowling games including tenpins, five-pins, duckpins and candlepins. Tenpins Pin specifications are set by the United States Bowling Congress (USBC). World Bowling, formerly World Tenpin Bowling Association, has adopted the USBC specifications. Pins are tall, wide at their widest point, and weigh ±. The first British made tenpin was by H Massil and sons who received the permit no.1 from the British Tenpin Bowling Association (BTBA) Duckpins and fivepins Duckpins are shorter and squatter than standard tenpins. Canadian fivepins are between duckpins and tenpins in size, but have a thick, inch-wide rubber band around the widest part of the pin to increase pin action when struck. Candlepins Candlepins are dissimilar to the others, being the tallest of all at 15-3/4 inches (40 cm), but only 2-15/16 inches wide and in weight, each pin nearly matching the maximum ...

Lapel Pin
A lapel pin, also known as an enamel pin, is a small pin worn on clothing, often on the lapel of a jacket, attached to a bag, or displayed on a piece of fabric. Lapel pins can be ornamental or can indicate the wearer's affiliation with an organization or cause. Before the popularity of wearing lapel pins, boutonnières were worn. Popular usage Lapel pins are frequently used as symbols of achievement and belonging in different organizations. Lapel pins from the organization are often collected by members and non-members alike. Businesses, corporates, & political parties also use lapel pins to designate achievement and membership.

Businesses also award lapel pins to employees more frequently to boost employee mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pin (chess)
In chess, a pin is a tactic in which a defending piece cannot move out of an attacking piece's line of attack without exposing a more valuable defending piece. Moving the attacking piece to effect the pin is called ''pinning''; the defending piece restricted by the pin is described as ''pinned''. Only a piece that can move any number of squares along a horizontal, vertical, or diagonal line (i.e. a bishop, rook, or queen) can pin. Any piece can be pinned except the king, which is the most valuable piece. The inverse of a pin is a skewer, in which a more valuable piece under direct attack may move to expose a less valuable piece to an attack. Types Absolute pin An ''absolute pin'' is one where the piece shielded by the pinned piece is the king. In this case it is illegal to move the pinned piece out of the line of attack, as that would place one's king in check (see diagram). A piece pinned in this way can still give check or defend another piece from capture by the opposing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pin (professional Wrestling)
In wrestling, a pin is achieved by holding an opponent's shoulders to the mat for a three count. Pinfall is the term used in professional wrestling which is a way to win the match for that person or team. Background A pinfall is a victory condition in various forms of professional wrestling that is met by holding (pinning) an opponent's shoulders on the wrestling mat, usually until the referee counts to three. In professional wrestling, a pinfall is a common method of winning a match. The origin of the pinfall is the pin from amateur wrestling, whereby pinning an opponent to the mat will result in a victory despite any points scored. However, while an amateur wrestling pin need be only one or two seconds, the count in professional wrestling is based on the referee's arm gestures, regardless of how much actual time elapses, and is to three slaps of the mat. The count is broken (a near-fall) if the opponent manages to raise one or both of their shoulders off the mat, commonly by ...

Safety Pin
The safety pin is a variation of the regular pin which includes a simple spring mechanism and a clasp. The clasp forms a closed loop to properly fasten the pin to whatever it is applied to and covers the end of the pin to protect the user from the sharp point. Safety pins are commonly used to fasten pieces of fabric or clothing together. Safety pins, or more usually a special version with an extra safe cover, called a nappy or loincloth pin, are widely used to fasten cloth diapers (nappies), or modern loincloths. They're preferred as their safety clasp, while remaining an ingestion hazard, prevents the baby from being jabbed or pricked. Safety pins can be used generally to patch torn or damaged clothing. They can also be used as an accessory in all kinds of jewelry including: earrings, chains, and wristbands. Sometimes they're used to attach an embroidered patch. Safety pins are divided into numbered size categories. With size 3 pins often being used in quilting and may be labelle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Media
Social media are interactive media technologies that facilitate the creation and sharing of information, ideas, interests, and other forms of expression through virtual communities and networks. While challenges to the definition of ''social media'' arise due to the variety of stand-alone and built-in social media services currently available, there are some common features: # Social media are interactive Web 2.0 Internet-based applications. # User-generated content—such as text posts or comments, digital photos or videos, and data generated through all online interactions—is the lifeblood of social media. # Users create service-specific profiles for the website or app that are designed and maintained by the social media organization. # Social media helps the development of online social networks by connecting a user's profile with those of other individuals or groups. The term ''social'' in regard to media suggests that platforms are user-centric and enable communal ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bobby Pin
A bobby pin (also known as a kirby grip or hair grip in the United Kingdom) is a type of hairpin, usually of metal or plastic, used in coiffure to hold hair in place. It is a small double-pronged hair pin or clip that slides into hair with the prongs open and then the flexible prongs close over the hair to hold it in place. They are typically plain and unobtrusively colored, but some are elaborately decorated or jeweled. Bobby pins became popular in the 1920s to hold the new bobbed hairstyles. Uses The main use of a bobby pin is to hold hair in place. In addition to bobbed hair, bobby pins are often used in up-dos, buns, and other hair styles where a sleek look is desired. To use a bobby pin in hair hold the hair in the desired position and push the bobby pin (straight side up) into place. Bobby pins can also be used to hold head coverings such as headbands, bandanna A kerchief (from the Old French ''couvrechief'', "cover head"), also known as a bandana, bandanna, or "Wil ...

Split Pin
A split pin, also known in the United States of America as a cotter pin or cotter key, is a metal fastener with two tines that are bent during installation, similar to a staple or rivet. Typically made of thick wire with a half-circular cross section, split pins come in multiple sizes and types. The British definition of "cotter pin" is equivalent to U.S. term " cotter". To avoid confusion, the term split cotter is sometimes used for a split pin. A further use of the term "cotter pin" is the "crank cotter pin" used to lock bicycle pedal cranks to the bottom bracket axle. These are not "split" at all and are wedge shaped. Construction A new split pin (see figure A) has its flat inner surfaces touching for most of its length so that it appears to be a split cylinder (figure D). Once inserted, the two ends of the pin are bent apart, locking it in place (figure B). When they are removed they are supposed to be discarded and replaced, because of fatigue from bending.

Clevis Pin
A clevis fastener is a two-piece fastener system consisting of a ''clevis'' and a ''clevis pin head''. The clevis is a U-shaped piece that has holes at the end of the prongs to accept the clevis pin. The clevis pin is similar to a bolt, but is either partially threaded or unthreaded with a cross-hole for a split pin. A ''tang'' is a piece that is sometimes fitted in the space within the clevis and is held in place by the clevis pin. The combination of a simple clevis fitted with a pin is commonly called a shackle, although a clevis and pin is only one of the many forms a shackle may take. Clevises are used in a wide variety of fasteners used in farming equipment and sailboat rigging, as well as the automotive, aircraft and construction industries. They are also widely used to attach control surfaces and other accessories to servo controls in airworthy model aircraft. As a part of a fastener, a clevis provides a method of allowing rotation in some axes while restricting rotat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drawing Pin
A drawing pin (in British English) or thumb tack (in North American English) is a short nail or pin used to fasten items to a wall or board for display and intended to be inserted by hand, usually using the thumb. A variety of names is used to refer to different designs intended for various purposes. Thumb tacks made of brass, tin or iron may be referred to as brass tacks, brass pins, tin tacks or iron tacks, respectively. These terms are particularly used in the idiomatic expression ''to come'' (or ''get'') ''down to brass'' (or otherwise) ''tacks'', meaning to consider basic facts of a situation. History The drawing pin was invented in name and first mass-produced in what is now the United States in the mid/late 1750s. It was first mentioned in the Oxford English Dictionary in 1759. It was said that the use of the newly invented drawing pin to attach notices to school house doors was making significant contribution to the whittling away of their gothic doors. Modern dra ...
