🔗 Business 🔗 Games

The beer distribution game (also known as the beer game) is a type of gamification that is used to experience typical coordination problems of a supply chain process. It reflects a role-play simulation where several participants play with each other. The game represents a supply chain with a non-coordinated process where problems arise due to lack of information sharing. This game outlines the importance of information sharing, supply chain management and collaboration throughout a supply chain process. Due to lack of information, suppliers, manufacturers, sales people and customers often have an incomplete understanding of what the real demand of an order is. The most interesting part of the game is that each group has no control over another part of the supply chain. Therefore, each group has only significant control over their own part of the supply chain. Each group can highly influence the entire supply chain by ordering too much or too little which can lead to a bullwhip effect. Therefore, the order taking of a group also highly depends on decisions of the other groups.

🔗 Time

The Doomsday rule is an algorithm of determination of the day of the week for a given date. It provides a perpetual calendar because the Gregorian calendar moves in cycles of 400 years. The algorithm for mental calculation was devised by John Conway in 1973, drawing inspiration from Lewis Carroll's perpetual calendar algorithm. It takes advantage of each year having a certain day of the week, called the doomsday, upon which certain easy-to-remember dates fall; for example, 4/4, 6/6, 8/8, 10/10, 12/12, and the last day of February all occur on the same day of the week in any year. Applying the Doomsday algorithm involves three steps: Determination of the anchor day for the century, calculation of the doomsday for the year from the anchor day, and selection of the closest date out of those that always fall on the doomsday, e.g., 4/4 and 6/6, and count of the number of days (modulo 7) between that date and the date in question to arrive at the day of the week. The technique applies to both the Gregorian calendar and the Julian calendar, although their doomsdays are usually different days of the week.

The algorithm is simple enough that it can be computed mentally. Conway can usually give the correct answer in under two seconds. To improve his speed, he practices his calendrical calculations on his computer, which is programmed to quiz him with random dates every time he logs on.

A True Story (Ancient Greek: Ἀληθῆ διηγήματα, Alēthē diēgēmata; Latin: Vera Historia or Latin: Verae Historiae) is a novel written in the second century AD by Lucian of Samosata, a Greek-speaking author of Assyrian descent. The novel is a satire of outlandish tales which had been reported in ancient sources, particularly those which presented fantastic or mythical events as if they were true. It is Lucian's best-known work.

It is the earliest known work of fiction to include travel to outer space, alien lifeforms, and interplanetary warfare. As such, A True Story has been described as "the first known text that could be called science fiction". However the work does not fit into typical literary genres: its multilayered plot and characters have been interpreted as science fiction, fantasy, satire or parody, and have been the subject of much scholarly debate.

The Toba supereruption was a supervolcanic eruption that occurred about 75,000 years ago at the site of present-day Lake Toba in Sumatra, Indonesia. It is one of the Earth's largest known eruptions. The Toba catastrophe theory holds that this event caused a global volcanic winter of six to ten years and possibly a 1,000-year-long cooling episode.

In 1993, science journalist Ann Gibbons posited that a population bottleneck occurred in human evolution about 70,000 years ago, and she suggested that this was caused by the eruption. Geologist Michael R. Rampino of New York University and volcanologist Stephen Self of the University of Hawaii at Manoa support her suggestion. In 1998, the bottleneck theory was further developed by anthropologist Stanley H. Ambrose of the University of Illinois at Urbana–Champaign. Both the link and global winter theories are controversial. The Toba event is the most closely studied supereruption.

🔗 Sports

Extreme ironing (also called EI) is an extreme sport in which people take ironing boards to remote locations and iron items of clothing. According to the Extreme Ironing Bureau, extreme ironing is "the latest danger sport that combines the thrills of an extreme outdoor activity with the satisfaction of a well-pressed shirt."

Part of the attraction and interest the media has shown towards extreme ironing seems to center on the issue of whether it is really a sport or not. It is widely considered to be tongue-in-cheek.

Some other locations where such performances have taken place include a mountainside of a difficult climb; a forest; in a canoe; while skiing or snowboarding; on top of large bronze statues; in the middle of a street; underwater; in the middle of the M1 motorway; race; whilst parachuting; and under the ice sheet of a frozen lake. The performances have been conducted solo or by groups.

The dead Internet theory is a theory that asserts that the Internet now consists almost entirely of bot activity and automatically generated content, marginalizing human activity. The date given for this "death" is generally around 2016 or 2017.

In 2012, YouTube removed billions of video views from major record labels, such as Sony and Universal, as a result of discovering that they had used fraudulent services to artificially increase the views of their content. The removal of the inflated views aimed to restore credibility to the platform and improve the accuracy of view counts. The move by YouTube also signaled a change in the way the platform would tackle fake views and bot traffic.

🔗 Philosophy 🔗 Philosophy/Logic 🔗 Philosophy/Epistemology

The unexpected hanging paradox or hangman paradox is a paradox about a person's expectations about the timing of a future event which they are told will occur at an unexpected time. The paradox is variously applied to a prisoner's hanging, or a surprise school test. It could be reduced to be Moore's paradox.

Despite significant academic interest, there is no consensus on its precise nature and consequently a final correct resolution has not yet been established. Logical analysis suggests that the problem arises in a self-contradictory self-referencing statement at the heart of the judge's sentence. Epistemological studies of the paradox have suggested that it turns on our concept of knowledge. Even though it is apparently simple, the paradox's underlying complexities have even led to its being called a "significant problem" for philosophy.

Li Wenliang (Chinese: 李文亮; pinyin: Lǐ Wénliàng; 12 October 1986 – 7 February 2020) was a Chinese ophthalmologist who worked as a physician at Wuhan Central Hospital. Li warned his colleagues in December 2019 about a possible outbreak of an illness that resembled severe acute respiratory syndrome (SARS), later acknowledged as COVID-19. He became a whistleblower when his warnings were later shared publicly. On 3 January 2020, Wuhan police summoned and admonished him for "making false comments on the Internet". Li returned to work, later contracted the virus from an infected patient (who had been originally treated for glaucoma) and died from the disease on 7 February 2020, at age 33. A subsequent Chinese official inquiry exonerated him and the Communist Party formally offered a "solemn apology" to his family and revoked its admonishment of him.

The Tiananmen Square protests, also known as the June Fourth Incident (Chinese: 六四事件; pinyin: liùsì shìjiàn) in China, were student-led demonstrations held in Tiananmen Square, Beijing during 1989. In what is known as the Tiananmen Square Massacre (Chinese: 天安门大屠杀; pinyin: Tiān'ānmén dà túshā), troops armed with assault rifles and accompanied by tanks fired at the demonstrators and those trying to block the military's advance into Tiananmen Square. The protests started on 15 April and were forcibly suppressed on 4 June when the government declared martial law and sent the People's Liberation Army to occupy parts of central Beijing. Estimates of the death toll vary from several hundred to several thousand, with thousands more wounded. The popular national movement inspired by the Beijing protests is sometimes called the '89 Democracy Movement (Chinese: 八九民运; pinyin: Bājiǔ mínyùn) or the Tiananmen Square Incident (Chinese: 天安门事件; pinyin: Tiān'ānmén shìjiàn).

The protests were precipitated by the death of pro-reform Chinese Communist Party (CCP) general secretary Hu Yaobang in April 1989 amid the backdrop of rapid economic development and social change in post-Mao China, reflecting anxieties among the people and political elite about the country's future. The reforms of the 1980s had led to a nascent market economy that benefited some people but seriously disadvantaged others, and the one-party political system also faced a challenge to its legitimacy. Common grievances at the time included inflation, corruption, limited preparedness of graduates for the new economy, and restrictions on political participation. Although they were highly disorganized and their goals varied, the students called for greater accountability, constitutional due process, democracy, freedom of the press, and freedom of speech. At the height of the protests, about one million people assembled in the Square.

As the protests developed, the authorities responded with both conciliatory and hardline tactics, exposing deep divisions within the party leadership. By May, a student-led hunger strike galvanized support around the country for the demonstrators, and the protests spread to some 400 cities. Among the CCP's top leadership, Premier Li Peng and Party Elders Li Xiannian and Wang Zhen called for decisive action through violent suppression of the protesters, and ultimately managed to win over Paramount Leader Deng Xiaoping and President Yang Shangkun to their side. On 20 May, the State Council declared martial law. They mobilized as many as ~300,000 troops to Beijing. The troops advanced into central parts of Beijing on the city's major thoroughfares in the early morning hours of 4 June, killing both demonstrators and bystanders in the process. The military operations were under the overall command of General Yang Baibing, half-brother of President Yang Shangkun.

The international community, human rights organizations, and political analysts condemned the Chinese government for the massacre. Western countries imposed arms embargoes on China. The Chinese government made widespread arrests of protesters and their supporters, suppressed other protests around China, expelled foreign journalists, strictly controlled coverage of the events in the domestic press, strengthened the police and internal security forces, and demoted or purged officials it deemed sympathetic to the protests. More broadly, the suppression ended the political reforms begun in 1986 and halted the policies of liberalization of the 1980s, which were only partly resumed after Deng Xiaoping's Southern Tour in 1992. Considered a watershed event, reaction to the protests set limits on political expression in China that have lasted up to the present day. Remembering the protests is widely associated with questioning the legitimacy of CCP rule and remains one of the most sensitive and most widely censored topics in China.

International Workers' Day, also called Labour Day in some countries and often referred to as May Day, is a celebration of labourers and the working classes that is promoted by the international labour movement and occurs every year on 1 May, or the first Monday in May.

Traditionally, 1 May is the date of the European spring festival of May Day. The International Workers Congress held in Paris in 1889 established the Second International for labor, socialist, and Marxist parties. It adopted a resolution for a "great international demonstration" in support of working-class demands for the eight-hour day. The date was chosen by the American Federation of Labor to commemorate a general strike in the United States, which had begun on 1 May 1886 and culminated in the Haymarket affair on 4 May. The demonstration subsequently became a yearly event. The 1904 Sixth Conference of the Second International, called on "all Social Democratic Party organisations and trade unions of all countries to demonstrate energetically on the First of May for the legal establishment of the eight-hour day, for the class demands of the proletariat, and for universal peace".

The 1st of May, or first Monday in May, is a national public holiday in many countries, in most cases known as "International Workers' Day" or a similar name. Some countries celebrate a Labour Day on other dates significant to them, such as the United States and Canada, which celebrate Labor Day on the first Monday of September. In 1955, the Catholic Church dedicated 1 May to "Saint Joseph the Worker". Saint Joseph is the patron saint of workers and craftsmen, among others.
