π Kwangmyong, the North-Korea-Wide-Web
Kwangmyong (literally βBright Lightβ) is a North Korean "walled garden" national intranet service opened in 2000.
The network uses domain names under the .kp top level domain that are not accessible from the global Internet. As of 2016 the network uses IPv4 addresses reserved for private networks in the 10.0.0.0/8 range. North Koreans often find it more convenient to access sites by their IP address rather than by URL using Latin characters. Like the global Internet, the network hosts content accessible with web browsers, and provides an internal web search engine. It also provides email services and news groups.
Only foreigners and a small number of government officials/scholars/elites are allowed to use the global Internet in North Korea, making Kwangmyong the only computer network available to most North Korean citizens. It is a free service for public use.

π St. Petersburg paradox
The St. Petersburg paradox or St. Petersburg lottery is a paradox related to probability and decision theory in economics. It is based on a particular (theoretical) lottery game that leads to a random variable with infinite expected value (i.e., infinite expected payoff) but nevertheless seems to be worth only a very small amount to the participants. The St. Petersburg paradox is a situation where a naive decision criterion which takes only the expected value into account predicts a course of action that presumably no actual person would be willing to take. Several resolutions are possible.
The paradox takes its name from its resolution by Daniel Bernoulli, one-time resident of the eponymous Russian city, who published his arguments in the Commentaries of the Imperial Academy of Science of Saint Petersburg (Bernoulli 1738). However, the problem was invented by Daniel's cousin, Nicolas Bernoulli, who first stated it in a letter to Pierre Raymond de Montmort on September 9, 1713 (de Montmort 1713).

π Organ harvesting from Falun Gong practitioners in China
Reports of forced organ harvesting from Falun Gong practitioners and other political prisoners in China have raised increasing concern within the international community. According to a report by former lawmaker David Kilgour, human rights campaigner David Matas and Victims of Communism Memorial Foundation researcher Ethan Gutmann, political prisoners, mainly Falun Gong practitioners, may be executed "on demand" in order to provide organs for transplant to recipients.
Reports on systematic organ harvesting from Falun Gong prisoners first emerged in 2006, though the practice is thought by some to have started six years earlier. Several researchersβmost notably Matas, Kilgour and Gutmannβestimate that tens of thousands of Falun Gong prisoners of conscience have been killed to supply a lucrative trade in human organs and cadavers and that these abuses may be ongoing. These conclusions are based on a combination of statistical analysis; interviews with former prisoners, medical authorities and public security agents; and circumstantial evidence, such as the large number of Falun Gong practitioners detained extrajudicially in China and the profits to be made from selling organs.
The Chinese government long denied all accusations of organ harvesting. However, the failure of Chinese authorities to effectively address or refute the charges has drawn attention and public condemnation from some governments, international organizations and medical societies. The parliaments of Canada and the European Union, as well as the U.S. Senate and House of Representatives, have adopted resolutions condemning the forced organ harvesting from Falun Gong prisoners of conscience. United Nations Special Rapporteurs have called on the Chinese government to account for the sources of organs used in transplant practices, and the World Medical Association, the American Society of Transplantation and the Transplantation Society have called for sanctions on Chinese medical authorities. Several countries have also taken or considered measures to deter their citizens from travelling to China for the purpose of obtaining organs. A documentary on organ harvesting from Falun Gong practitioners, Human Harvest, received a 2014 Peabody Award recognizing excellence in broadcast journalism. China eventually admitted that it had engaged in systematic organ harvesting from death row prisoners, though it denies that such an organ harvesting program is ongoing.
π Small Is Beautiful: Economics As If People Mattered
Small Is Beautiful: A Study of Economics As If People Mattered is a collection of essays by German-born British economist E. F. Schumacher. The phrase "Small Is Beautiful" came from a principle espoused by Schumacher's teacher Leopold Kohr (1937-1994) The concept is often used to champion small, appropriate technologies or polities that are believed to empower people more, in contrast with phrases such as "bigger is better".
First published in 1973, Small Is Beautiful brought Schumacher's critiques of Western economics to a wider audience during the 1973 energy crisis and the popularisation of the concept of globalization. In 1995 The Times Literary Supplement ranked Small Is Beautiful among the 100 most influential books published since World War II. A further edition with commentaries was published in 1999.

π First Council of Nicaea
The First Council of Nicaea ( ny-SEE-Ι; Ancient Greek: Ξ£ΟΞ½ΞΏΞ΄ΞΏΟ ΟαΏΟ ΞΞΉΞΊΞ±Ξ―Ξ±Ο, romanized:Β SΓ½nodos tΓͺs NikaΓas) was a council of Christian bishops convened in the Bithynian city of Nicaea (now Δ°znik, Turkey) by the Roman Emperor Constantine I. The Council of Nicaea met from May until the end of July 325.
This ecumenical council was the first of many efforts to attain consensus in the church through an assembly representing all Christendom. Hosius of Corduba may have presided over its deliberations. Its main accomplishments were settlement of the Christological issue of the divine nature of God the Son and his relationship to God the Father, the construction of the first part of the Nicene Creed, mandating uniform observance of the date of Easter, and promulgation of early canon law.

π Shellac
Shellac () is a resin secreted by the female lac bug on trees in the forests of India and Thailand. Chemically, it is mainly composed of aleuritic acid, jalaric acid, shellolic acid, and other natural waxes. It is processed and sold as dry flakes and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and seals out moisture. Phonograph and 78Β rpm gramophone records were made of shellac until they were replaced by vinyl long-playing records from 1948 onwards.
From the time shellac replaced oil and wax finishes in the 19th century, it was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the 1920s and 1930s.

π Whipping Boy
A whipping boy was a boy educated alongside a prince (or boy monarch) in early modern Europe, who received corporal punishment for the prince's transgressions in his presence. The prince was not punished himself because his royal status exceeded that of his tutor; seeing a friend punished would provide an equivalent motivation not to repeat the offence. An archaic proverb which captures a similar idea is "to beat a dog before a lion." Whipping was a common punishment of tutors at that time. There is little contemporary evidence for the existence of whipping boys, and evidence that some princes were indeed whipped by their tutors, although Nicholas Orme suggests that nobles might have been beaten less often than other pupils. Some historians regard whipping boys as entirely mythical; others suggest they applied only in the case of a boy king, protected by divine right, and not to mere princes.
In Renaissance humanism, Erasmus' treatises "The Education of a Christian Prince" (1516) and "Declamatio de pueris statim ac liberaliter instituendis" (1530) mention the inappropriateness of physical chastisement of princes, but do not mention proxy punishment. Hartley Coleridge wrote in 1852, "to be flogged by proxy was the exclusive privilege of royal blood. ... It was much coveted for the children of the poorer gentry, as the first step in the ladder of preferment." John Gough Nichols wrote in 1857, "the whole matter is somewhat legendary, and though certain vicarious or rather minatory punishments may have been occasionally adopted, it does not seem likely that any one individual among the King's schoolfellows should have been uniformly selected, whether he were in fault or not, as the victim or scape-goat of the royal misdemeanours". In current English, a "whipping boy" is a metaphor which may have a similar meaning to scapegoat, fall guy, or sacrificial lamb; alternatively it may mean a perennial loser or a victim of group bullying.

π Circulation of Elites
The circulation of elite is a theory of regime change described by Italian social scientist Vilfredo Pareto (1848β1923).
Changes of regime, revolutions, and so on occur not when rulers are overthrown from below, but when one elite replaces another. The role of ordinary people in such transformation is not that of initiators or principal actors, but as followers and supporters of one elite or another.

π List of mass shootings in the United States in 2022
This is a list of shootings in the United States that have occurred in 2022. Mass shootings are incidents involving several victims of firearm-related violence. The precise inclusion criteria are disputed, and there is no broadly accepted definition.
Gun Violence Archive, a nonprofit research group, run by Tracy Holtan, that tracks shootings and their characteristics in the United States, defines a mass shooting as an incident in which four or more people, excluding the perpetrator(s), are shot in one location at roughly the same time. The Congressional Research Service narrows that definition, limiting it to "public mass shootings", defined by four or more victims killed, excluding any victims who survive. The Washington Post and Mother Jones use similar definitions, with the latter acknowledging that their definition "is a conservative measure of the problem", as many shootings with fewer fatalities occur. The crowdsourced Mass Shooting Tracker project has the most expansive definition of four or more shot in any incident, including the perpetrator in the victim inclusion criteria.
A 2019 study of mass shootings published in the journal Injury Epidemiology recommended developing "a standard definition that considers both fatalities and nonfatalities to most appropriately convey the burden of mass shootings on gun violence." The authors of the study further suggested that "the definition of mass shooting should be four or more people, excluding the shooter, who are shot in a single event regardless of the motive, setting or number of deaths."
