Cité (Paris Métro)

Cité (French pronunciation: ​[site]) is a metro station on Line 4 of the Paris Métro in the 4th arrondissement of Paris.

Location

Cité station lies underneath the Île de la Cité, one of two islands on the Seine within the historical boundaries of Paris. In relation to the rest of the city, it lies within the 4th arrondissement, near Kilometre Zero, the official geographical and historical centre of Paris. The only station on the Île de la Cité, it lies near many famous landmarks, the most famous being the Cathedral of Notre Dame. To the west are the Sainte-Chapelle chapel and the Palace of Justice, while Notre Dame and the Hôtel-Dieu are to the east.

History

The station was opened on 10 December 1910 on the section of the line under the Seine between Châtelet and Raspail. This section of the line had actually opened on 9 January 1910 but trains passed through the station without stopping until the December of that year.

Tunnels were later built linking the station to the nearby Prefecture of Police of Paris and the Palais de Justice. However, for security reasons, these tunnels have now been closed for more than thirty years.

Types of municipalities in Quebec

The following is a list of the types of local and supralocal territorial units in Quebec, including those used solely for statistical purposes, as defined by the Ministry of Municipal Affairs, Regions and Land Occupancy and compiled by the Institut de la statistique du Québec.

Not included are the urban agglomerations of Quebec, which, although they group together multiple municipalities, exercise only what are ordinarily local municipal powers.

A list of local municipal units in Quebec by regional county municipality can be found at List of municipalities in Quebec.

Local municipalities

All municipalities (except cities), whether township, village, parish, or unspecified ones, are functionally and legally identical. The only difference is that the designation might serve to disambiguate between otherwise identically-named municipalities, often neighbouring ones. Many such cases have had their names changed, or merged with the identically-named nearby municipality since the 1950s, such as the former Township of Granby and City of Granby merging and becoming the Town of Granby in 2007.

Keynote (presentation software)

Keynote is a presentation software application developed as a part of the iWork productivity suite by Apple Inc. Keynote 6.0 was announced on October 23, 2013 and is the most recent version for the Mac. On January 27, 2010, Apple announced a new version of Keynote for iPad with an all new touch interface.

History

Keynote began as a computer program for Apple CEO Steve Jobs to use in creating the presentations for Macworld Conference and Expo and other Apple keynote events. Prior to using Keynote, Jobs had used Concurrence, from Lighthouse Design, a similar product which ran on the NeXTSTEP and OpenStep platforms.

The program was first sold publicly as Keynote 1.0 in 2003, competing against existing presentation software, most notably Microsoft PowerPoint.

In 2005 Apple began selling Keynote 2.0 in conjunction with Pages, a new word processing and page layout application, in a software package called iWork. At the Macworld Conference & Expo 2006, Apple released iWork '06 with updated versions of Keynote 3.0 and Pages 2.0. In addition to official HD compatibility, Keynote 3 added new features, including group scaling, 3D charts, multi-column text boxes, auto bullets in any text field, image adjustments, and free form masking tools. In addition, Keynote features three-dimensional transitions, such as a rotating cube or a simple flip of the slide.

Database index

A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.

An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by letting developers create indices on functions or expressions. For example, an index could be created on upper(last_name), which would only store the upper case versions of the last_name field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Key (music)

In music theory, the key of a piece is the tonic note and chord that provides a subjective sense of arrival and rest. Other notes and chords in the piece create varying degrees of tension, resolved when the tonic note or chord returns. The key may be major or minor, although major is assumed in a phrase like "this piece is in C." Popular songs are usually in a key, and so is classical music during the common practice period, about 1650–1900. Longer pieces in the classical repertoire may have sections in contrasting keys.

Methods that establish the key for a particular piece can be complicated to explain, and vary over music history. However, the chords most often used in a piece in a particular key are those that contain the notes in the corresponding scale, and conventional progressions of these chords, particularly cadences, orient the listener around the tonic.

The key signature is not a reliable guide to the key of a written piece. It does not discriminate between a major key and its relative minor; the piece may modulate to a different key; if the modulation is brief, it may not involve a change of key signature, being indicated instead with accidentals. Occasionally, a piece in a mode such as Mixolydian or Dorian is written with a major or minor key signature appropriate to the tonic, and accidentals throughout the piece.
