Official (ice hockey)

In ice hockey, an official is a person who has some responsibility in enforcing the rules and maintaining the order of the game. There are two categories of officials, on-ice officials, who are the referees and linesmen that enforce the rules during game play, and off-ice officials, who have an administrative role rather than an enforcement role.

On-ice officials

As the name implies, on-ice officials do their job on the hockey rink. They are traditionally clad in a black hockey helmet, black trousers, and a black-and-white striped shirt. They wear standard hockey skates and carry a finger whistle, which they use to stop play. They communicate with players, coaches, off-ice officials, both verbally and via hand signals. Starting in 1955 with the introduction of the black-and-white jersey, NHL on-ice officials wore numbers on their back for identification. In 1977, NHL officials removed the number and had their surnames on the back of their jerseys for identification, normally in a single row across the shoulders. (Some officials with long names would have their name in two rows, the most notable example being Andy Van Hellemond.) Starting in 1994, however, NHL officials returned to wearing numbers on their shirts, a procedure adopted by other leagues.

Referee

A referee is the person of authority in a variety of sports who is responsible for presiding over the game from a neutral point of view and making on-the-fly decisions that enforce the rules of the sport, including sportsmanship decisions such as ejection. The official tasked with this job may be known, in addition to referee, by a variety of other titles as well (often depending on the sport), including umpire, judge, arbiter, arbitrator, linesman, commissaire, timekeeper, touch judge or Technical Official (by the International Olympic Committee).

Origin

The term referee originated in association football. Originally the team captains would consult with each other in order to resolve any dispute on the pitch. Eventually this role was delegated to an umpire. Each team would bring their own partisan umpire allowing the team captains to concentrate on the game. Later, the referee, a third "neutral" official was added, this referee would be "referred to" if the umpires could not resolve a dispute. The referee did not take his place on the pitch until 1891, when the umpires became linesmen (now assistant referees). Today, in many amateur football matches, each side will still supply their own partisan assistant referees (still commonly called club linesmen) to assist the neutral referee appointed by the governing football association if one or both assistant referees are not provided. In this case, the role of the linesmen is limited to indicating out of play and cannot decide off side.

Official (American football)

In American football, an official is a person who has responsibility in enforcing the rules and maintaining the order of the game.

During professional and most college football games, seven officials operate on the field. Beginning in 2015, Division I college football conferences are using eight game officials. College games outside the Division I level use six or seven officials. Arena football, high school football, and other levels of football have other officiating systems. High school football played under the National Federation of State High School Associations (NFHS) rules typically use five officials for varsity and 3, 4, or 5 for non-varsity games.

Football officials are commonly, but incorrectly, referred to as referees, but each position has specific duties and a specific name: referee, umpire, head linesman, line judge, back judge, side judge, center judge (in Division I college football) and field judge. Because the referee is responsible for the general supervision of the game, the position is sometimes referred to as head referee or crew chief.

Trailer music

Trailer music (a subset of production music) is the background music used for film previews, which is not always from the film's soundtrack. The purpose of this music is to complement, support and integrate the sales messaging of the mini-movie that is a film trailer. Because the score for a movie is usually composed after the film is finished (which is much after trailers are released), a trailer will incorporate music from other sources. Sometimes music from other successful films or hit songs is used as a subconscious tie-in method.

The music used in the trailer may be (or may have suggestive derivatives from):

Trailer (vehicle)

A trailer is generally an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials.

Sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities, where people can camp or stay have been referred to as trailers. In earlier days, many such vehicles were towable trailers.

United States

In the United States, the term is sometimes used interchangeably with travel trailer and mobile home, varieties of trailers and manufactured housing designed for human habitation. Their origins lay in utility trailers built in a similar fashion to horse-drawn wagons. A trailer park is an area where mobile homes are placed for habitation.

In the United States trailers ranging in size from single-axle dollies to 6-axle, 13 ft 6 in (4,115 mm) high, 53 ft 0 in (16,154 mm) long semi-trailers are commonplace. The latter, when towed as part of a tractor-trailer or "18-wheeler", carries a large percentage of the freight that travels over land in North America.

CrossOver (software)

CrossOver is a Microsoft Windows compatibility layer available for Mac OS and Linux. This compatibility layer enables many Windows-based applications to run on Mac OS or Linux operating systems.

CrossOver is developed by CodeWeavers and based on Wine, an open-source Windows compatibility layer. CodeWeavers modifies the Wine source code, applies compatibility patches, adds configuration tools that are more user-friendly, automated installation scripts, and provides technical support. All changes made to the Wine source code are covered by the LGPL and publicly available on WineHQ.

Versions

CrossOver Mac

In 2005 Apple announced a transition from PowerPC to Intel processors in their computers, which allowed CodeWeavers develop a Mac OS X version of CrossOver Office called 'CrossOver Mac'

CrossOver Mac was released on January 10, 2007. With the release of CrossOver Mac 7 on June 17, 2008, CrossOver Mac was divided into Standard and Pro editions like CrossOver Linux. The Standard version included six months of support and upgrades, while the Pro version included one year of support and upgrades, along with a free copy of CrossOver Games. With the release of CrossOver Mac 11 in 2012 these different editions were all merged into a single CrossOver Mac product.

Crossover (automobile)

A crossover, also known as a crossover utility vehicle (CUV), is a vehicle built on a car platform and combining, in highly variable degrees, features of a sport utility vehicle (SUV) with features from a passenger vehicle, especially those of a station wagon or hatchback.

Using the unibody construction typical of passenger vehicles instead of the body-on-frame platform used in light trucks and the original SUVs, the crossover combines SUV design features such as tall interior packaging, high H-point seating, high center of gravity, high ground-clearance or all-wheel-drive capability – with design features from an automobile such as a passenger vehicle's platform, independent rear suspension, car-like handling and superior fuel economy.

A crossover may borrow features from a station wagon or hatchback, such as the two-box design of a shared passenger/cargo volume with rear access via a third or fifth door, a liftgate – and flexibility to allow configurations that favor either passenger or cargo volume, e.g., fold-down rear seats.
