🔗 Indigenous peoples of North America

Several Native American tribes within the United States register motor vehicles and issue license plates to those vehicles.

The legal status of these plates varies by tribe, with some being recognized by the federal government and others not. Some nations issue plates for both tribal and personal vehicles, while others issue plates only for official tribal vehicles.

Some nations' plates indicate the U.S. state with which they are most closely associated, while others do not. This variation may even exist among the nations associated with one particular state.

Federally recognized tribes may also lease vehicles through the U.S. General Services Administration under certain circumstances. Such vehicles carry U.S. government license plates.

The Law of Jante (Danish: Janteloven) is a code of conduct known in Nordic countries that characterizes not conforming, doing things out of the ordinary, or being overtly personally ambitious as unworthy and inappropriate. The attitudes were first formulated in the form of the ten rules of Jante Law by the Dano-Norwegian author Aksel Sandemose in his satirical novel A Fugitive Crosses His Tracks (En flyktning krysser sitt spor, 1933), but the actual attitudes themselves are older. Sandemose portrays the fictional small Danish town Jante, which he modelled upon his native town Nykøbing Mors in the 1930s, where nobody was anonymous, which is typical of all small towns and communities.

Used generally in colloquial speech in the Nordic countries as a sociological term to denote a social attitude of disapproval towards expressions of individuality and personal success, it emphasizes adherence to the collective.

K-219 was a Project 667A Navaga-class ballistic missile submarine (NATO reporting name Yankee I) of the Soviet Navy. It carried 16 R-27U liquid-fuel missiles powered by UDMH with nitrogen tetroxide (NTO), and equipped with either 32 or 48 nuclear warheads.K-219 was involved in what has become one of the most controversial submarine incidents during the Cold War on Friday 3 October 1986. The 15-year-old vessel, which was on an otherwise routine Cold War nuclear deterrence patrol in the North Atlantic 1,090 kilometres (680 mi) northeast of Bermuda, suffered an explosion and fire in a missile tube. While underway submerged the seal in a missile hatch cover failed, allowing high-pressure seawater to enter the missile tube and owing to the pressure differential rupture the missile fuel tanks, allowing missile's liquid fuel to mix and ultimately combust. Though there was no official announcement, the Soviet Union claimed the leak was caused by a collision with the submarine USS Augusta. Although Augusta was operating within the area, both the United States Navy and the commander of K-219, Captain Second Rank Igor Britanov, deny that a collision took place.

The incident was novelized in the book Hostile Waters, which reconstructed the incident from descriptions by the survivors, ships' logs, the official investigations, and participants both ashore and afloat from the Soviet and the American sides.

The Hurrian songs are a collection of music inscribed in cuneiform on clay tablets excavated from the ancient Amorite-Canaanite city of Ugarit, a headland in northern Syria, which date to approximately 1400 BCE. One of these tablets, which is nearly complete, contains the Hurrian hymn to Nikkal (also known as the Hurrian cult hymn or A Zaluzi to the Gods, or simply h.6), making it the oldest surviving substantially complete work of notated music in the world. While the composers' names of some of the fragmentary pieces are known, h.6 is an anonymous work.

Conway's law is an adage stating that organizations design systems that mirror their own communication structure. It is named after computer programmer Melvin Conway, who introduced the idea in 1967. His original wording was:

Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.

The law is based on the reasoning that in order for a software module to function, multiple authors must communicate frequently with each other. Therefore, the software interface structure of a system will reflect the social boundaries of the organization(s) that produced it, across which communication is more difficult. Conway's law was intended as a valid sociological observation, although sometimes it's used in a humorous context. It was dubbed Conway's law by participants at the 1968 National Symposium on Modular Programming.

In colloquial terms, it means software or automated systems end up "shaped like" the organizational structure they are designed in or designed for. Some interpretations of the law say this organizational pattern mirroring is a helpful feature of such systems, while other interpretations say it's merely a result of human nature or organizational bias.

🔗 Lists 🔗 Languages 🔗 Endangered languages

This is a list of extinct languages sorted by their time of extinction. A language is determined to be an extinct when its last native or fluent speaker dies. When the exact time of death of the last remaining speaker is not known, either an approximate time or the date when the language was last being recorded is given.

🔗 Anthropology 🔗 Athletics 🔗 Running 🔗 Evolutionary biology

The endurance running hypothesis is the hypothesis that the evolution of certain human characteristics can be explained as adaptations to long-distance running. The hypothesis suggests that endurance running played an important role for early hominins in obtaining food. Researchers have proposed that endurance running began as an adaptation for scavenging and later for persistence hunting.

🔗 Mathematics 🔗 Statistics

In mathematics, the theory of optimal stopping or early stopping is concerned with the problem of choosing a time to take a particular action, in order to maximise an expected reward or minimise an expected cost. Optimal stopping problems can be found in areas of statistics, economics, and mathematical finance (related to the pricing of American options). A key example of an optimal stopping problem is the secretary problem. Optimal stopping problems can often be written in the form of a Bellman equation, and are therefore often solved using dynamic programming.

🔗 Military history 🔗 Military history/African military history 🔗 Ethiopia 🔗 Military history/British military history

The British Expedition to Abyssinia was a rescue mission and punitive expedition carried out in 1868 by the armed forces of the British Empire against the Ethiopian Empire. Emperor Tewodros II of Ethiopia, then often referred to by the anglicized name Theodore, imprisoned several missionaries and two representatives of the British government in an attempt to get the attention of the British government, which had decided against his requests for military assistance. The punitive expedition launched by the British in response required the transportation of a sizable military force hundreds of miles across mountainous terrain lacking any road system. The formidable obstacles to the action were overcome by the commander of the expedition, General Sir Robert Napier, who was victorious in every battle with the troops of Tewodros, captured the Ethiopian capital and rescued all the hostages. The expedition was widely hailed on its return for achieving all its objectives.

Harold G. Marcus described the action as "one of the most expensive affairs of honour in history."

The alcohol belts of Europe divide Europe by their traditional alcoholic beverages: beer, wine, or spirits. They do not necessarily correspond with current drinking habits, as beer has become the most popular alcoholic drink world-wide. The definitions of these belts are not completely objective.
