Opera is a web browser developed by Opera Software. The latest version is available for Microsoft Windows, OS X, and Linux operating systems, and uses the Blink layout engine. An earlier version using the Presto layout engine is still available, and additionally runs on FreeBSD systems.
Opera siblings – Opera Mobile, Opera Mini and Opera Coast – work on devices running Android, iOS, Windows Phone, Symbian, Maemo, Bada, BlackBerry and Windows Mobile operating systems, while Opera Mini runs on Java ME-capable devices.
According to Opera Software, the browser had more than 350 million users worldwide in the 4th quarter 2014. Total Opera mobile users reached 291 million in June 2015. Opera has been noted for originating many features later adopted by other web browsers. A prominent example is Speed Dial.
Opera began in 1994 as a research project at Telenor, the largest Norwegian telecommunications company. In 1995, it branched out into a separate company named Opera Software ASA. Opera was first released publicly with version 2.0 in 1996, which only ran on Microsoft Windows. In an attempt to capitalize on the emerging market for Internet-connected handheld devices, a project to port Opera to mobile device platforms was started in 1998. Opera 4.0, released in 2000, included a new cross-platform core that facilitated creation of editions of Opera for multiple operating systems and platforms.
Opera is a monthly British magazine devoted to covering all things related to opera. It contains reviews and articles about current opera productions internationally, as well as articles on opera recordings, opera singers, opera companies, opera directors, and opera books. The magazine also contains major features and analysis on individual operas and people associated with opera.
The magazine employs a network of international correspondents around the world who write for the magazine. Contributors to the magazine, past and present, include William Ashbrook, Martin Bernheimer, Julian Budden, Rodolfo Celletti, Alan Blyth, Elizabeth Forbes, and J.B. Steane among many others.
Opera is printed in A5 size, with colour photos, and consists of around 130 pages. Page numbering is consecutive for a complete year (e.g. September 2009 goes from p1033-1168). All issues since August 2006 are available online to current subscribers (through Exact Editions).
Based in London, the magazine was founded in 1950 by George Lascelles, 7th Earl of Harewood. It was launched at the house of Richard Buckle, under the imprint 'Ballet Publications Ltd'.
Ópera is a station on Line 2, Line 5 and Ramal of the Madrid Metro. It is located in fare Zone A, in the Plaza de Isabel II, in the central district of Madrid. The station provides access to an area with tourist landmarks such as Teatro Real, Plaza de Oriente and the Royal Palace. Its name comes from nearby Madrid opera house, the Teatro Real.
The station was opened to the public in 1925 for lines 2 and Ramal later that year. Its original name was Isabel II, under the square in which it stood. The platforms of lines 2 and Ramal are located at the same level, the former is 60 m long and the latter being shorter in the beginning, but later it was extended in length to 60 m, too.
After the proclamation of the Second Republic on 14 April 1931, the new authorities approved by Decree of 20 April the removal of all the denominations that made references to the monarchy. Therefore, on 24 June Isabel II station was renamed Ópera. That same year, the square also changed his name to Fermín Galán, one of the leaders of the failed uprising in 1930 tried to overthrow King Alfonso XIII. On 5 June 1937 the station changed its name to coincide with the square. However, after the establishment of the dictatorship of Francisco Franco there was a further change in the names of city streets, stations, etc. Therefore, in 1939 the square was again renamed Isabel II, and the metro station recovered the name Ópera.
Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).
The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares. In mathematics, the unit square is defined to have area one, and the area of any other shape or surface is a dimensionless real number.
An area is an administrative unit of The Church of Jesus Christ of Latter-day Saints (LDS Church), which typically is composed of multiple stakes and missions. Areas are the primary church administrative unit between individual stakes and the church as a whole.
The areas as they now exist were formed in January 1984. Prior to that time, general authorities served as "area supervisors" and at times resided outside of Salt Lake City. In 1984, 13 initial areas were created; by 1992 there were 22, and by early 2007 there were 31. As of August 2012 there are 25 areas.
Until 2003, each area had a president and two counselors, all of whom were typically general authorities (area seventies were sometimes asked to be counselors). This three-man body was known as the area presidency. In that year, the church eliminated area presidencies for all areas located in the United States and Canada. Each of these areas were placed under the direct supervision of one of the seven members of the Presidency of the Seventy, thus freeing more general authorities from specific area assignments. Since these areas were previously administered by area presidencies located at church headquarters in Salt Lake City, the administrative change was not as drastic as it might seem.
In graph drawing, the area used by a drawing is a commonly used way of measuring its quality.
For a drawing style in which the vertices are placed on the integer lattice, the area of the drawing may be defined as the area of the smallest axis-aligned bounding box of the drawing: that is, it the product of the largest difference in x-coordinates of two vertices with the largest difference in y-coordinates. For other drawing styles, in which vertices are placed more freely, the drawing may be scaled so that the closest pair of vertices have distance one from each other, after which the area can again be defined as the area of a smallest bounding box of a drawing. Alternatively, the area can be defined as the area of the convex hull of the drawing, again after appropriate scaling.
For straight-line drawings of planar graphs with n vertices, the optimal worst-case bound on the area of a drawing is Θ(n2). The nested triangles graph requires this much area no matter how it is embedded, and several methods are known that can draw planar graphs with at most quadratic area.Binary trees, and trees of bounded degree more generally, have drawings with linear or near-linear area, depending on the drawing style. Every outerplanar graph has a straight-line outerplanar drawing with area subquadratic in its number of vertices, If bends or crossings are allowed, then outerplanar graphs have drawings with near-linear area. However, drawing series-parallel graphs requires an area larger than n by a superpolylogarithmic factor, even if edges can be drawn as polylines.
Coming from the wilderness
Found by a little boy
Sold to some soldiers
He became their toy
But soon they saw his value
And made him one of them
He helped them fight the evil
Over and over again
Woytek – the soldier bear
Woytek – the soldier bear
He bears the shells
He eats syrup and honey
But also cigarettes
And he drinks beer

And he drinks beer
From the companies mascot
To their official emblem
The hero of the 22nd
Not like any man
Proud and tall he stands
The grenades in his paws
Marching of to war
Strong forevermore
