The Conversation is a 1974 American mystery thriller film written, produced and directed by Francis Ford Coppola and starring Gene Hackman with supporting roles by John Cazale, Allen Garfield, Cindy Williams, Frederic Forrest, Harrison Ford, Teri Garr and Robert Duvall.

The plot revolves around a surveillance expert and the moral dilemma he faces when his recordings reveal a potential murder. Coppola cited the 1966 film Blowup as a key influence. However, since the film was released to theaters just a few months before Richard Nixon resigned as President, he felt that audiences interpreted the film to be a reaction to the Watergate scandal. The Conversation has won critical acclaim and multiple accolades, including the Grand Prix du Festival International du Film, the highest honor at the 1974 Cannes Film Festival. It was nominated for three Academy Awards in 1974 and lost Best Picture to The Godfather Part II, another Francis Ford Coppola film. In 1995, it was selected for preservation in the National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".

A folk legend holds that in October 1593 a soldier of the Spanish Empire (named Gil Pérez in a 1908 version) was mysteriously transported from Manila in the Philippines to the Plaza Mayor (now the Zócalo) in Mexico City. The soldier's claim to have come from the Philippines was disbelieved by the Mexicans until his account of the assassination of Gómez Pérez Dasmariñas was corroborated months later by the passengers of a ship which had crossed the Pacific Ocean with the news. Folklorist Thomas Allibone Janvier in 1908 described the legend as "current among all classes of the population of the City of Mexico". Twentieth-century paranormal investigators giving credence to the story have offered teleportation and alien abduction as explanations.

WikimediaUI Dark mode is a gadget for enabling dark mode in modern browsers, based on experimental work of Wikimedia Design team members Volker E. and Alex Hollender in support by volunteer MusikAnimal and others.

Preview dark mode on the Main Page.

To enable, go to your gadget preferences, and enable the gadget "Dark mode toggle: Enable a toggle for using a light text on dark background color scheme".

You should now see a "Dark mode" switch at the top of pages. If you wish to enable/disable dark mode automatically based on your system colour scheme, add the following to your common.js page:

Any modern browser works with the only exception being Opera Mini, which lacks filter support.

The CSS was written with Wikipedia sites in mind (see phab:T221425) so experience on other wikis may not be optimal.

To set up the gadget on your wiki, ask an interface-admin to do the following:

• Create the pages MediaWiki:Gadget-dark-mode.css, MediaWiki:Gadget-dark-mode-toggle-pagestyles.css and MediaWiki:Gadget-dark-mode-toggle.js by copying the English Wikipedia versions. Adjust the localisation strings as appropriate.
  • While the CSS pages need to be copied to avoid FOUCs arising from slow load, for the JS page you may instead dynamically load the enwiki version:
  • Replace "Dark mode" and "Light mode" after content: in the CSS files with the localised labels.
• Add to MediaWiki:Gadgets-definition:
• Add the following to the bottom of MediaWiki:Gadgets-definition. This is an internal gadget which can't be marked as hidden, for technical reasons.
• Create the gadget description pages MediaWiki:Gadget-dark-mode-toggle (the main "dark mode" gadget) and MediaWiki:Gadget-dark-mode (this is the internal gadget – make sure the description is such that users don't enable this one).

The gadget has several limitations due to the way it achieves the dark mode. Known issues are:

• It can be slow, especially on larger pages.
• Images are colorshifted
• Native Emojis are inverted
• Text only SVGs with transparent backgrounds can be unreadable (as they are treated as images, and thus do not get dark mode)
• The color legends in captions, might not match the colors of images for maps and/or graphs.

Most problems are due to how the gadget was implemented. It first inverts and colorshifts the entire page, and then tries to 'undo' the areas you do not want inverted, such as images. The benefit to this approach is that it takes care of dark mode everywhere, without having hundreds and hundreds of lines of codes for all the nooks and crannies of Wikipedia/MediaWiki that have their own styling. The downside are the problems listed.

For an example of what to expect on invert "dark mode" and double-invert "undo", see the question pictures in this StackOverflow question. The question uses the same invert and hue-rotate filter used by this extension.

The Google effect, also called digital amnesia, is the tendency to forget information that can be found readily online by using Internet search engines. According to the first study about the Google effect people are less likely to remember certain details they believe will be accessible online. However, the study also claims that people's ability to learn information offline remains the same. This effect may also be seen as a change to what information and what level of detail is considered to be important to remember.

🔗 Game theory

The Price of Anarchy (PoA) is a concept in economics and game theory that measures how the efficiency of a system degrades due to selfish behavior of its agents. It is a general notion that can be extended to diverse systems and notions of efficiency. For example, consider the system of transportation of a city and many agents trying to go from some initial location to a destination. Let efficiency in this case mean the average time for an agent to reach the destination. In the 'centralized' solution, a central authority can tell each agent which path to take in order to minimize the average travel time. In the 'decentralized' version, each agent chooses its own path. The Price of Anarchy measures the ratio between average travel time in the two cases.

Usually the system is modeled as a game and the efficiency is some function of the outcomes (e.g. maximum delay in a network, congestion in a transportation system, social welfare in an auction, ...). Different concepts of equilibrium can be used to model the selfish behavior of the agents, among which the most common is the Nash equilibrium. Different flavors of Nash equilibrium lead to variations of the notion of Price of Anarchy as Pure Price of Anarchy (for deterministic equilibria), Mixed Price of Anarchy (for randomized equilibria), and Bayes–Nash Price of Anarchy (for games with incomplete information). Solution concepts other than Nash equilibrium lead to variations such as the Price of Sinking.

The term Price of Anarchy was first used by Elias Koutsoupias and Christos Papadimitriou, but the idea of measuring inefficiency of equilibrium is older. The concept in its current form was designed to be the analogue of the 'approximation ratio' in an approximation algorithm or the 'competitive ratio' in an online algorithm. This is in the context of the current trend of analyzing games using algorithmic lenses (algorithmic game theory).

The Svalbard Global Seed Vault (Norwegian: Svalbard globale frøhvelv) is a secure seed bank on the Norwegian island of Spitsbergen in the remote Arctic Svalbard archipelago. Conservationist Cary Fowler, in association with the Consultative Group on International Agricultural Research (CGIAR), started the vault to preserve a wide variety of plant seeds that are duplicate samples, or "spare" copies, of seeds held in gene banks worldwide. The seed vault is an attempt to ensure against the loss of seeds in other genebanks during large-scale regional or global crises. The seed vault is managed under terms spelled out in a tripartite agreement among the Norwegian government, the Crop Trust, and the Nordic Genetic Resource Center (NordGen).

The Norwegian government entirely funded the vault's approximately 45 million kr (US$8.8 million in 2008) construction. Storing seeds in the vault is free to end users; Norway and the Crop Trust pay for operational costs. Primary funding for the Trust comes from organisations such as the Bill & Melinda Gates Foundation and from various governments worldwide.

Spermaceti is a waxy substance found in the head cavities of the sperm whale (and, in smaller quantities, in the oils of other whales). Spermaceti is created in the spermaceti organ inside the whale's head. This organ may contain as much as 1,900 litres (500 US gal) of spermaceti. It has been extracted by whalers since the 17th century for human use in cosmetics, textiles, and candles.

Theories for the spermaceti organ's biological function suggest that it may control buoyancy, may act as a focusing apparatus for the whale's sense of echolocation, or possibly both. There has been concrete evidence to support both theories. The buoyancy theory holds that the sperm whale is capable of heating the spermaceti, lowering its density and thus allowing the whale to float; in order for the whale to sink again, it must take water into its blowhole which cools the spermaceti into a denser solid. This claim has been called into question by recent research which indicates a lack of biological structures to support this heat exchange, as well as the fact that the change in density is too small to be meaningful until the organ grows to huge size. Measurement of the proportion of wax esters retained by a harvested sperm whale accurately described the age and future life expectancy of a given individual. The proportion of wax esters in the spermaceti organ increases with the age of the whale: 38–51% in calves, 58–87% in adult females, and 71–94% in adult males.

Spermaceti wax is extracted from sperm oil by crystallisation at 6 °C (43 °F), when treated by pressure and a chemical solution of caustic alkali. Spermaceti forms brilliant white crystals that are hard but oily to the touch, and are devoid of taste or smell, making it very useful as an ingredient in cosmetics, leatherworking, and lubricants. The substance was also used in making candles of a standard photometric value, in the dressing of fabrics, and as a pharmaceutical excipient, especially in cerates and ointments.

The whaling industry in the 17th and 18th centuries was developed to find, harvest and refine the contents of the head of a sperm whale. The crews seeking spermaceti routinely left on three-year tours on several oceans. Cetaceous lamp oil was a commodity that created many maritime fortunes. The light produced by a single pure spermaceti source (candle) became the standard measurement of "candlepower" for another century. Candlepower, a photometric unit defined in the United Kingdom Act of Parliament Metropolitan Gas Act 1860 and adopted at the International Electrotechnical Conference of 1883, was based on the light produced by a pure spermaceti candle.
