In economics, the Gini coefficient ( JEE-nee), sometimes called the Gini index or Gini ratio, is a measure of statistical dispersion intended to represent the income or wealth distribution of a nation's residents, and is the most commonly used measurement of inequality. It was developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper Variability and Mutability (Italian: Variabilità e mutabilità).

The Gini coefficient measures the inequality among values of a frequency distribution (for example, levels of income). A Gini coefficient of zero expresses perfect equality, where all values are the same (for example, where everyone has the same income). A Gini coefficient of one (or 100%) expresses maximal inequality among values (e.g., for a large number of people, where only one person has all the income or consumption, and all others have none, the Gini coefficient will be very nearly one). For larger groups, values close to one are very unlikely in practice. Given the normalization of both the cumulative population and the cumulative share of income used to calculate the Gini coefficient, the measure is not overly sensitive to the specifics of the income distribution, but rather only on how incomes vary relative to the other members of a population. The exception to this is in the redistribution of income resulting in a minimum income for all people. When the population is sorted, if their income distribution were to approximate a well-known function, then some representative values could be calculated.

The Gini coefficient was proposed by Gini as a measure of inequality of income or wealth. For OECD countries, in the late 20th century, considering the effect of taxes and transfer payments, the income Gini coefficient ranged between 0.24 and 0.49, with Slovenia being the lowest and Mexico the highest. African countries had the highest pre-tax Gini coefficients in 2008–2009, with South Africa the world's highest, variously estimated to be 0.63 to 0.7, although this figure drops to 0.52 after social assistance is taken into account, and drops again to 0.47 after taxation. The global income Gini coefficient in 2005 has been estimated to be between 0.61 and 0.68 by various sources.

There are some issues in interpreting a Gini coefficient. The same value may result from many different distribution curves. The demographic structure should be taken into account. Countries with an aging population, or with a baby boom, experience an increasing pre-tax Gini coefficient even if real income distribution for working adults remains constant. Scholars have devised over a dozen variants of the Gini coefficient.

Verlan (French pronunciation: ​[vɛʁlɑ̃]), (verlan is the reverse of the expression "l'envers") is a type of argot in the French language, featuring inversion of syllables in a word, and is common in slang and youth language. It rests on a long French tradition of transposing syllables of individual words to create slang words. The name verlan itself is an example: it is derived from inverting the sounds of the syllables in l'envers ([lɑ̃vɛʁ], "the inverse", frequently used in the sense of "back-to-front").

🔗 Computing 🔗 Computing/Software

Delphi is an event-driven programming language based on Object Pascal and an associated integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies.

Delphi's compilers generate native code for Microsoft Windows, macOS, iOS, Android and Linux (x64 only). Since 2016, there have been new releases of Delphi every six months, with new platforms being added approximately every second release.

Delphi includes a code editor, a visual designer, an integrated debugger, a source code control component, and support for third-party plugins. The code editor features Code Insight (code completion), Error Insight (real-time error-checking), and refactoring. The visual forms designer has traditionally used Visual Component Library (VCL) for native Windows development, but the FireMonkey (FMX) platform was later added for cross-platform development. Database support in Delphi is very strong. A Delphi project of a million lines of code can compile in a few seconds – one benchmark compiled 170,000 lines per second.

Delphi was originally developed by Borland as a rapid application development tool for Windows as the successor of Turbo Pascal. Delphi added full object-oriented programming to the existing language, and since then the language has grown to support generics and anonymous methods, and native Component Object Model (COM) support. In 2006, Borland’s developer tools section was transferred from Borland to a wholly owned subsidiary known as CodeGear, which was sold to Embarcadero Technologies in 2008. In 2015, Embarcadero was purchased by Idera Software, but the Embarcadero mark was retained for the developer tools division.

Delphi and its C++ counterpart, C++Builder, are interoperable. They share many core components, notably the IDE, VCL, and much of the runtime library. In addition, they can be used jointly in a project. For example, C++Builder 6 and later can consume Delphi source code and C++ in one project, while packages compiled with C++Builder can be used from within Delphi. In 2007, the products were released jointly as RAD Studio, a shared host for Delphi and C++Builder, which can be purchased with either or both.

The Lockheed bribery scandals encompassed a series of bribes and contributions made by officials of U.S. aerospace company Lockheed from the late 1950s to the 1970s in the process of negotiating the sale of aircraft.

The scandal caused considerable political controversy in West Germany, Italy, the Netherlands and Japan. In the U.S., the scandal nearly led to Lockheed's downfall, as it was already struggling due to the commercial failure of the L-1011 TriStar airliner.

On 2 April 1979, spores of anthrax were accidentally released from a Soviet military research facility near the city of Sverdlovsk, Russia (now Yekaterinburg). The ensuing outbreak of the disease resulted in approximately 100 deaths, although the exact number of victims remains unknown. The cause of the outbreak was denied for years by the Soviet authorities, which blamed the deaths on consumption of tainted meat from the area, and subcutaneous exposure due to butchers handling the tainted meat. All medical records of the victims were removed to hide serious violations of the Biological Weapons Convention. The accident is sometimes referred to as "biological Chernobyl".

The Affero General Public License (Affero GPL and informally Affero License) is a free software license. The first version of the Affero General Public License (AGPLv1), was published by Affero, Inc. in March 2002, and based on the GNU General Public License, version 2 (GPLv2). The second version (AGPLv2) was published in November 2007, as a transitional license to allow an upgrade path from AGPLv1 to the GNU Affero General Public License (a variant of the original Affero GPL license that is compatible with GPLv3).

Both versions of the Affero GPL were designed to close a perceived application service provider (ASP) loophole in the ordinary GPL, where, by using but not distributing the software, the copyleft provisions are not triggered. Each version differs from the version of the GNU GPL on which it is based in having an added provision addressing use of software over a computer network. This provision requires that the full source code be made available to any network user of the AGPL-licensed work, typically a web application.

A nuclear close call is an incident that could lead to, or could have led to at least one unintended nuclear detonation/explosion. These incidents typically involve a perceived imminent threat to a nuclear-armed country which could lead to retaliatory strikes against the perceived aggressor. The damage caused by international nuclear exchange is not necessarily limited to the participating countries, as the hypothesized rapid climate change associated with even small-scale regional nuclear war could threaten food production worldwide—a scenario known as nuclear famine.

Despite a reduction in global nuclear tensions and major nuclear arms reductions after the end of the Cold War (in 1989), estimated nuclear warhead stockpiles total roughly 15,000 worldwide, with the United States and Russia holding 90% of the total.

Though exact details on many nuclear close calls are hard to come by, the analysis of particular cases has highlighted the importance of a variety of factors in preventing accidents. At an international level, this includes the importance of context and outside mediation; at the national level, effectiveness in government communications, and involvement of key decision-makers; and, at the individual level, the decisive role of individuals in following intuition and prudent decision-making, often in violation of protocol.

The Satellaview is a satellite modem peripheral produced by Nintendo for the Super Famicom in 1995. Containing 1 megabit of ROM space and an additional 512K of RAM, Satellaview allowed players to download games, magazines and other forms of content through satellite broadcasts provided by Japanese company St.GIGA. To use Satellaview, players had to purchase a special broadcast satellite (BS) tuner directly from St.GIGA or rent one for a six-month fee, and to pay monthly maintenance fees to both St.GIGA and Nintendo. It was attached to the bottom of the Super Famicom via the system's expansion port. It featured heavy support from third-party developers, including Squaresoft, Taito, Konami, Capcom and Seta.

Satellaview was the result of a collaboration between Nintendo and St.GIGA, the latter being known in Japan for its "Tide of Sound" nature sound music. By 1994, St.GIGA was struggling financially due to the Japanese Recession affecting the demand for its music; Nintendo initiated a "rescue" plan by purchasing a stake in the company. Satellaview was produced by Nintendo Research & Development 2, the same team that designed the Super Famicom itself, and was made to cater towards a more adult-oriented market. By 1998, Nintendo's relationship with St.GIGA was beginning to collapse due to the company refusing to go forward with a debt-management plan and failing to secure a government broadcasting license. Nintendo withdrew support for Satellaview in March 1999, with St.GIGA continuing to supply content until June 30, 2000, when it was ultimately discontinued.

The rise of technologically-superior consoles such as the Sega Saturn and PlayStation and its high cost made consumers reluctant to purchase Satellaview, especially due to it only being sold via mail order, or through specific electronic store chains. Despite this, St.GIGA reported seeing over 100,000 subscribers by March 1997. Retrospectively, Satellaview has been praised by critics for its technological accomplishments and the overall quality of its games, particularly those from the Legend of Zelda series. In recent years, it has gained a strong cult following due to much of its content being deemed lost, with video game preservation groups being formed to dump and preserve its games and other services online.

Ishikawa diagrams (also called fishbone diagrams, herringbone diagrams, cause-and-effect diagrams, or Fishikawa) are causal diagrams created by Kaoru Ishikawa that show the causes of a specific event.

Common uses of the Ishikawa diagram are product design and quality defect prevention to identify potential factors causing an overall effect. Each cause or reason for imperfection is a source of variation. Causes are usually grouped into major categories to identify and classify these sources of variation.
