Hall (concept)

The meanings attributed to the word hall have varied over the centuries, as social practices have changed. The word derives from the Old Teutonic (hallâ), where it is associated with the idea of covering or concealing. In modern German it is Halle where it refers to a building but Saal where it refers to a large public room though the distinction is blurred:(Halle (Architektur) (de)). The latter may arise from a genitive form of the former. The French salle is borrowed from the German.

Simple beginnings

The Oxford English Dictionary gives nine meanings of hall relevant to buildings with a root of the word meaning "...to cover, conceal." A hall is, fundamentally, a relatively large space enclosed by a roof such as a market hall. Coming from the Old English language, it was brought into Britain in the fifth century.

A hall is also a large, public or stately room in a building.

Hall also may refer to a building itself where meetings or events occur such as Westminster Hall, a concert hall, a Guild hall, town hall.

Concept (band)

Concept is an Italian progressive power metal band, formed in 2000.

History

After a short experience under the name of A.T.T. (About Traverse Tracks) and after releasing the EP "Abstractive Fallacy" in September 1999, Mariano Croce, Andrea Mastroianni, Gianni Carcione and David Folchitto (now Stormlord, Prophilax), in January 2000, formed the band Concept, producing their first EP "Time Before" in February 2000. In June 2000 they signed a deal with the record label Underground Symphony. Soon after, the bass player Andrea Arcangeli (now DGM) joined the band.

Their first full-length cd Reason and Truth was recorded in the spring of 2001 at the Zenith Studios (Lucca – Italy); because of some negative circumstances, the cd will be mixed only in October 2002, at the New Sin Studio (Loria (TV) – Italy), and released in 2003.
On March 1, 2005, the band released their second album, The Divine Cage, recorded between May and June 2004 at the Cromas Studios (Rome - Italy) and at the New Sin Studio by Luigi Stefanini.

Concept (generic programming)

In generic programming, a concept is a description of supported operations on a type, including syntax and semantics. In this way, concepts are related to abstract base classes but concepts do not require a subtype relationship.

Language use

The term was in use as early as 1998 for STL, as this was one of the first libraries that extensively used templates.

In the C++ 1998 standard, the Concept term was introduced to name just a simple description of the requirements for particular type, usually being a template parameter. It was not encoded in the language explicitly – the concept was expressed only by what operations are tried to be performed on objects of that type and what is expected to work (that is, to compile correctly). There was a proposal to add concepts as an explicit language feature in C++11, though it was rejected as "not ready".

As generics in Java and C# have some similarities to C++'s templates, the role of concepts there is played by interfaces. However, there is one important difference between concepts and interfaces: when a template parameter is required to implement a particular interface, the matching type can only be a class that implements (explicitly) that interface. Concepts bring more flexibility because they can be satisfied by two ways:

Hall

In architecture, a hall is a relatively large space enclosed by a roof and walls. In the Iron Age, a mead hall was such a simple building and was the residence of a lord and his retainers. Later, rooms were partitioned from it, and the space next to the front door became the entrance hall. Today, the (entrance) hall of a house is the space next to the front door or vestibule leading to the rooms directly and/or indirectly. Where the hall inside the front door of a house is elongated, it may be called a passage, corridor (from Spanish corredor used in El Escorial and 100 years later in Castle Howard) or hallway.

Other meanings

The term hall is often used to designate a British or Irish country house such as a hall house, or specifically a Wealden hall house, and manor houses.

In later medieval Europe, the main room of a castle or manor house was the great hall. In a medieval building, the hall was where the fire was kept. With time, its functions as dormitory, kitchen, parlour and so on were divided off to separate rooms or, in the case of the kitchen, a separate building.

Hall (cyclecar)

The Hall Cycle and Plating company was a maker of Cycle cars in Waco, Texas from 1914-1915.

History

In 1914, a man named John B. Fisher designed a cyclecar for the Hall Cycle and Plating Company. It had an underslung frame.Lawrence Hall, president of the company, did a test run from Waco to Dallas, covering 104 miles while consuming only 2.5 gallons of gasoline. The cyclecar had a 4-cylinder, 18 hp engine(the prototype only had a two-cylinder engine) with a 100" wheelbase. The company reorganized in 1915 as the Hall Motor car Company. Production ended in 1915, and Lawrence Hall moved to Los Angeles.
