The paradox of hedonism, also called the pleasure paradox, refers to the practical difficulties encountered in the pursuit of pleasure. For the hedonist, constant pleasure-seeking may not yield the most actual pleasure or happiness in the long run—or even in the short run, when consciously pursuing pleasure interferes with experiencing it.

The utilitarian philosopher Henry Sidgwick was first to note in The Methods of Ethics that the paradox of hedonism is that pleasure cannot be acquired directly. Variations on this theme appear in the realms of ethics, philosophy, psychology, and economics.

British Airways Flight 9, sometimes referred to by its callsign Speedbird 9 or as the Jakarta incident, was a scheduled British Airways flight from London Heathrow to Auckland, with stops in Bombay, Kuala Lumpur, Perth, and Melbourne.

On 24 June 1982, the route was flown by the City of Edinburgh, a Boeing 747-200. The aircraft flew into a cloud of volcanic ash thrown up by the eruption of Mount Galunggung (approximately 110 miles (180 km) south-east of Jakarta, Indonesia), resulting in the failure of all four engines. The reason for the failure was not immediately apparent to the crew or air traffic control. The aircraft was diverted to Jakarta in the hope that enough engines could be restarted to allow it to land there. The aircraft glided out of the ash cloud, and all engines were restarted (although one failed again soon after), allowing the aircraft to land safely at the Halim Perdanakusuma Airport in Jakarta.

The crew members of the accident segment had boarded the aircraft in Kuala Lumpur, while many of the passengers had been aboard since the flight began in London.

Yuri Alekseyevich Gagarin  (9 March 1934 – 27 March 1968) was a Soviet Air Forces pilot and cosmonaut who became the first human to journey into outer space, achieving a major milestone in the Space Race; his capsule Vostok 1 completed one orbit of Earth on 12 April 1961. Gagarin became an international celebrity and was awarded many medals and titles, including Hero of the Soviet Union, his nation's highest honour.

Born in the village of Klushino near Gzhatsk (a town later renamed after him), in his youth Gagarin was a foundryman at a steel plant in Lyubertsy. He later joined the Soviet Air Forces as a pilot and was stationed at the Luostari Air Base, near the Norwegian border, before his selection for the Soviet space programme with five other cosmonauts. Following his spaceflight, Gagarin became deputy training director of the Cosmonaut Training Centre, which was later named after him. He was also elected as a deputy of the Soviet of the Union in 1962 and then to the Soviet of Nationalities, respectively the lower and upper chambers of the Supreme Soviet.

Vostok 1 was Gagarin's only spaceflight but he served as the backup crew to the Soyuz 1 mission, which ended in a fatal crash, killing his friend and fellow cosmonaut Vladimir Komarov. Fearing for his life, Soviet officials permanently banned Gagarin from further spaceflights. After completing training at the Zhukovsky Air Force Engineering Academy on 17 February 1968, he was allowed to fly regular aircraft. Gagarin died five weeks later when the MiG-15 training jet he was piloting with his flight instructor Vladimir Seryogin crashed near the town of Kirzhach.

🔗 Law 🔗 United Kingdom 🔗 Politics of the United Kingdom

The Statute of Anne, also known as the Copyright Act 1710 (cited either as 8 Ann. c. 21 or as 8 Ann. c. 19), is an act of the Parliament of Great Britain passed in 1710, which was the first statute to provide for copyright regulated by the government and courts, rather than by private parties.

Prior to the statute's enactment in 1710, copying restrictions were authorized by the Licensing of the Press Act 1662. These restrictions were enforced by the Stationers' Company, a guild of printers given the exclusive power to print—and the responsibility to censor—literary works. The censorship administered under the Licensing Act led to public protest; as the act had to be renewed at two-year intervals, authors and others sought to prevent its reauthorisation. In 1694, Parliament refused to renew the Licensing Act, ending the Stationers' monopoly and press restrictions.

Over the next 10 years the Stationers repeatedly advocated bills to re-authorize the old licensing system, but Parliament declined to enact them. Faced with this failure, the Stationers decided to emphasise the benefits of licensing to authors rather than publishers, and the Stationers succeeded in getting Parliament to consider a new bill. This bill, which after substantial amendments was granted Royal Assent on 5 April 1710, became known as the Statute of Anne owing to its passage during the reign of Queen Anne. The new law prescribed a copyright term of 14 years, with a provision for renewal for a similar term, during which only the author and the printers to whom they chose to license their works could publish the author's creations. Following this, the work's copyright would expire, with the material falling into the public domain. Despite a period of instability known as the Battle of the Booksellers when the initial copyright terms under the Statute began to expire, the Statute of Anne remained in force until the Copyright Act 1842 replaced it.

The statute is considered a "watershed event in Anglo-American copyright history ... transforming what had been the publishers' private law copyright into a public law grant". Under the statute, copyright was for the first time vested in authors rather than publishers; it also included provisions for the public interest, such as a legal deposit scheme. The Statute was an influence on copyright law in several other nations, including the United States, and even in the 21st century is "frequently invoked by modern judges and academics as embodying the utilitarian underpinnings of copyright law".

Hugin () is a cross-platform open source panorama photo stitching and HDR merging program developed by Pablo d'Angelo and others. It is a GUI front-end for Helmut Dersch's Panorama Tools and Andrew Mihal's Enblend and Enfuse. Stitching is accomplished by using several overlapping photos taken from the same location, and using control points to align and transform the photos so that they can be blended together to form a larger image. Hugin allows for the easy (optionally automatic) creation of control points between two images, optimization of the image transforms along with a preview window so the user can see whether the panorama is acceptable. Once the preview is correct, the panorama can be fully stitched, transformed and saved in a standard image format.

🔗 Climate change 🔗 Meteorology 🔗 Chemistry

In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body or similar space. Water or various other chemicals may compose the droplets and crystals. On Earth, clouds are formed as a result of saturation of the air when it is cooled to its dew point, or when it gains sufficient moisture (usually in the form of water vapor) from an adjacent source to raise the dew point to the ambient temperature.

They are seen in the Earth's homosphere (which includes the troposphere, stratosphere, and mesosphere). Nephology is the science of clouds, which is undertaken in the cloud physics branch of meteorology.

The two methods of naming clouds in their respective layers of the atmosphere are Latin and common. Cloud types in the troposphere, the atmospheric layer closest to Earth's surface, have Latin names due to the universal adoption of Luke Howard's nomenclature. Formally proposed in 1802, it became the basis of a modern international system that divides clouds into five physical forms that appear in any or all of three altitude levels (formerly known as étages). These physical types, in approximate ascending order of convective activity, include stratiform sheets, cirriform wisps and patches, stratocumuliform layers (mainly structured as rolls, ripples, and patches), cumuliform heaps, and very large cumulonimbiform heaps that often show complex structures. The physical forms are divided by altitude level into 10 basic genus-types.

The Latin names for applicable high-level genera in the troposphere carry a cirro- prefix, and an alto- prefix is added to the names of the mid-level genus-types. Clouds with sufficient vertical extent to occupy more than one altitude level are officially classified as low- or mid-level according to the altitude range at which each initially forms. However they are also more informally classified as multi-level or vertical, which along with low level clouds, do not carry any altitude related prefixes. Most of the genera can be subdivided into species and further subdivided into varieties. Very low stratiform clouds that extend down to the Earth's surface are given the common names fog and mist, but have no Latin names.

Several cloud types that form higher up in the stratosphere and mesosphere have common names for their main types, which may have the appearance of stratiform sheets, cirriform wisps, or statocumuliform bands or ripples. They are seen infrequently, mostly in the polar regions of Earth. Clouds have been observed in the atmospheres of other planets and moons in the Solar System and beyond. However, due to their different temperature characteristics, they are often composed of other substances such as methane, ammonia, and sulfuric acid, as well as water.

The tabular overview that follows is very broad in scope. It draws from several methods of cloud classification, both formal and informal, used in different levels of the Earth's homosphere by a number of cited authorities. Despite some differences in methodologies and terminologies, the classification schemes seen in this article can be harmonized by using a cross-classifation of form and level to derive the 10 tropospheric genera, the fog and mist that forms at surface level, and several additional major types above the troposphere. The cumulus genus includes four species that indicate vertical size and structure. This table should therefore not be seen as a strict or singular classification, but as an illustration of how various major cloud types are related to each other and defined through a full range of altitude levels from Earth's surface to the "edge of space".

A Request for Comments (RFC), in the context of Internet governance, is a type of publication from the Internet Engineering Task Force (IETF) and the Internet Society (ISOC), usually describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems.

Almost every April Fools' Day (1 April) since 1989, the Internet RFC Editor has published one or more humorous Request for Comments (RFC) documents, following in the path blazed by the June 1973 RFC 527 called ARPAWOCKY, a parody of Lewis Carroll's nonsense poem "Jabberwocky". The following list also includes humorous RFCs published on other dates.

🔗 Psychology 🔗 Cognitive science

Functional fixedness is a cognitive bias that limits a person to use an object only in the way it is traditionally used. The concept of functional fixedness originated in Gestalt psychology, a movement in psychology that emphasizes holistic processing. Karl Duncker defined functional fixedness as being a "mental block against using an object in a new way that is required to solve a problem". This "block" limits the ability of an individual to use components given to them to complete a task, as they cannot move past the original purpose of those components. For example, if someone needs a paperweight, but they only have a hammer, they may not see how the hammer can be used as a paperweight. Functional fixedness is this inability to see a hammer's use as anything other than for pounding nails; the person couldn't think to use the hammer in a way other than in its conventional function.

When tested, 5-year-old children show no signs of functional fixedness. It has been argued that this is because at age 5, any goal to be achieved with an object is equivalent to any other goal. However, by age 7, children have acquired the tendency to treat the originally intended purpose of an object as special.

The acquisition of Sun Microsystems by Oracle Corporation was completed on January 27, 2010. Significantly, Oracle, previously only a software vendor, now owned both hardware and software product lines from Sun (e.g. SPARC Enterprise and Java, respectively).

A major issue of the purchase was that Sun was a major competitor to Oracle, raising many concerns among antitrust regulators, open source advocates, customers, and employees. The EU Commission delayed the acquisition for several months over concerns of Oracle's plans for MySQL, Sun's competitor to the Oracle Database. The commission finally approved the takeover, apparently pressured by the United States to do so, according to a WikiLeaks cable released in September 2011.

XeTeX ( ZEE-tekh or ; see also Pronouncing and writing "TeX") is a TeX typesetting engine using Unicode and supporting modern font technologies such as OpenType, Graphite and Apple Advanced Typography (AAT). It was originally written by Jonathan Kew and is distributed under the X11 free software license.

Initially developed for Mac OS X only, it is now available for all major platforms. It natively supports Unicode and the input file is assumed to be in UTF-8 encoding by default. XeTeX can use any fonts installed in the operating system without configuring TeX font metrics, and can make direct use of advanced typographic features of OpenType, AAT and Graphite technologies such as alternative glyphs and swashes, optional or historic ligatures, and variable font weights. Support for OpenType local typographic conventions (locl tag) is also present. XeTeX even allows raw OpenType feature tags to be passed to the font. Microtypography is also supported. XeTeX also supports typesetting mathematics using Unicode fonts that contain special mathematical features, such as Cambria Math or Asana Math as an alternative to the traditional mathematical typesetting based on TeX font metrics.
