🔗 List of games that Buddha would not play
The Buddhist games list is a list of games that Gautama Buddha is reputed to have said that he would not play and that his disciples should likewise not play, because he believed them to be a 'cause for negligence'. This list dates from the 6th or 5th century BCE and is the earliest known list of games.
There is some debate about the translation of some of the games mentioned, and the list given here is based on the translation by T. W. Rhys Davids of the Brahmajāla Sutta and is in the same order given in the original. The list is duplicated in a number of other early Buddhist texts, including the Vinaya Pitaka.
- Games on boards with 8 or 10 rows. This is thought to refer to ashtapada and dasapada respectively, but later Sinhala commentaries refer to these boards also being used with games involving dice.
- The same games played on imaginary boards. Akasam astapadam was an ashtapada variant played with no board, literally "astapadam played in the sky". A correspondent in the American Chess Bulletin identifies this as likely the earliest literary mention of a blindfold chess variant.
- Games of marking diagrams on the floor such that the player can only walk on certain places. This is described in the Vinaya Pitaka as "having drawn a circle with various lines on the ground, there they play avoiding the line to be avoided". Rhys Davids suggests that it may refer to parihāra-patham, a form of hop-scotch.
- Games where players either remove pieces from a pile or add pieces to it, with the loser being the one who causes the heap to shake (similar to the modern game pick-up sticks).
- Games of throwing dice.
- "Dipping the hand with the fingers stretched out in lac, or red dye, or flour-water, and striking the wet hand on the ground or on a wall, calling out 'What shall it be?' and showing the form required—elephants, horses, &c."
- Ball games.
- Blowing through a pat-kulal, a toy pipe made of leaves.
- Ploughing with a toy plough.
- Playing with toy windmills made from palm leaves.
- Playing with toy measures made from palm leaves.
- Playing with toy carts.
- Playing with toy bows.
- Guessing at letters traced with the finger in the air or on a friend's back.
- Guessing a friend's thoughts.
- Imitating deformities.
Although the modern game of chess had not been invented at the time the list was made, earlier chess-like games such as chaturaji may have existed. H.J.R. Murray refers to Rhys Davids' 1899 translation, noting that the 8×8 board game is most likely ashtapada while the 10×10 game is dasapada. He states that both are race games.

🔗 Morrison Shelter
Air raid shelters, also known as bomb shelters, are structures for the protection of non-combatants as well as combatants against enemy attacks from the air. They are similar to bunkers in many regards, although they are not designed to defend against ground attack (but many have been used as defensive structures in such situations).
Prior to World War II, in May 1924, an Air Raid Precautions Committee was set up in the United Kingdom. For years, little progress was made with shelters because of the apparently irreconcilable conflict between the need to send the public underground for shelter and the need to keep them above ground for protection against gas attacks. In February 1936 the Home Secretary appointed a technical Committee on Structural Precautions against Air Attack.
By November 1937, there had only been slow progress, because of a serious lack of data on which to base any design recommendations and the Committee proposed that the Home Office should have its own department for research into structural precautions, rather than relying on research work done by the Bombing Test Committee to support the development of bomb design and strategy. This proposal was eventually implemented in January 1939.
During the Munich crisis, local authorities dug trenches to provide shelter. After the crisis, the British Government decided to make these a permanent feature, with a standard design of precast concrete trench lining. Unfortunately these turned out to perform very poorly. They also decided to issue free to poorer households the Anderson shelter, and to provide steel props to create shelters in suitable basements.
🔗 The Third Wave Experiment
The Third Wave was an experimental social movement created by California high school history teacher Ron Jones in 1967 to explain how the German population could accept the actions of the Nazi regime during the Second World War. While he taught his students about Nazi Germany during his "Contemporary World History" class, Jones found it difficult to explain how the German people could accept the actions of the Nazis, and decided to create a social movement as a demonstration of the appeal of fascism. Over the course of five days, Jones – a member of the SDS, Cubberley United Student Movement sponsor and Black Panthers supporter – conducted a series of exercises in his classroom emphasizing discipline and community, intended to model certain characteristics of the Nazi movement. As the movement grew outside his class and began to number in the hundreds, Jones began to feel that the movement had spiraled out of control. He convinced the students to attend a rally where he claimed that the classroom project was part of a nationwide movement, and that the announcement of a Third Wave presidential candidate would be televised. Upon their arrival, the students were presented with a blank channel. Jones told his students of the true nature of the movement as an experiment in fascism, and presented to them a short film discussing the actions of Nazi Germany.

🔗 Cultural Revolution
The Cultural Revolution, formally the Great Proletarian Cultural Revolution, was a sociopolitical movement in China from 1966 until 1976. Launched by Mao Zedong, Chairman of the Communist Party of China (CPC), its stated goal was to preserve Chinese Communism by purging remnants of capitalist and traditional elements from Chinese society, and to re-impose Mao Zedong Thought (known outside China as Maoism) as the dominant ideology in the CPC. The Revolution marked Mao's return to the central position of power in China after a period of less radical leadership to recover from the failures of the Great Leap Forward, which led to approximately 30 million deaths in the Great Chinese Famine only five years prior.
Launching the movement in May 1966 with the help of the Cultural Revolution Group, Mao soon called on young people to "bombard the headquarters", and proclaimed that "to rebel is justified". In order to eliminate his rivals within the CPC and in schools, factories, and government institutions, Mao charged that bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. He insisted that revisionists be removed through violent class struggle, to which China's youth, as well as urban workers, responded by forming Red Guards and "rebel groups" around the country. They would begin to hold struggle sessions regularly, and grab power from local governments and CPC branches, eventually establishing the revolutionary committees in 1967. The groups often split into rival factions, however, becoming involved in 'violent struggles' (simplified Chinese: 武斗; traditional Chinese: 武鬥; pinyin: wǔdòu), to which the People's Liberation Army had to be sent to restore order.
Having compiled a selection of Mao's sayings into the Little Red Book, which became a sacred text for Mao's personality cult, Lin Biao, Vice Chairman of the CPC, was written into the constitution as Mao's successor. In 1969, Mao suggested the end of the Cultural Revolution. However, the Revolution's active phase would last until at least 1971, when Lin Biao, accused of a botched coup against Mao, fled and died in a plane crash. In 1972, the Gang of Four rose to power and the Cultural Revolution continued. After Mao's death and the arrest of the Gang of Four in 1976, the Cultural Revolution finally came to an end.
The Cultural Revolution damaged China's economy and traditional culture, with an estimated death toll ranging from hundreds of thousands to 20 million. Beginning with the Red August of Beijing, massacres took place across China, including the Guangxi Massacre, in which massive cannibalism also occurred; the Inner Mongolia incident; the Guangdong Massacre; the Yunnan Massacres; and the Hunan Massacres. Red Guards destroyed historical relics and artifacts, as well as ransacking cultural and religious sites. The 1975 Banqiao Dam failure, one of the world's greatest technological catastrophes, also occurred during the Cultural Revolution. Meanwhile, tens of millions of people were persecuted: senior officials, most notably Chinese president Liu Shaoqi, along with Deng Xiaoping, Peng Dehuai, and He Long, were purged or exiled; millions were accused of being members of the Five Black Categories, suffering public humiliation, imprisonment, torture, hard labor, seizure of property, and sometimes execution or harassment into suicide; intellectuals were considered the "Stinking Old Ninth" and were widely persecuted—notable scholars and scientists such as Lao She, Fu Lei, Yao Tongbin, and Zhao Jiuzhang were killed or committed suicide. Schools and universities were closed with the college entrance exams cancelled. Over 10 million urban intellectual youths were sent to the countryside in the Down to the Countryside Movement.
In 1978, Deng Xiaoping became the new paramount leader of China and started the "Boluan Fanzheng" program which gradually dismantled the Maoist policies associated with the Cultural Revolution, and brought the country back to order. Deng then began a new phase of China by initiating the historic Reforms and Opening-Up program. In 1981, the Communist Party of China declared that the Cultural Revolution was "responsible for the most severe setback and the heaviest losses suffered by the Party, the country, and the people since the founding of the People's Republic."

🔗 Dené–Yeniseian Languages
Dené–Yeniseian is a proposed language family consisting of the Yeniseian languages of central Siberia and the Na-Dené languages of northwestern North America.
Reception among experts has been largely, though not universally, favorable; thus, Dené–Yeniseian has been called "the first demonstration of a genealogical link between Old World and New World language families that meets the standards of traditional comparative-historical linguistics," besides the Eskimo–Aleut languages spoken in far eastern Siberia and North America.

🔗 History of software engineering
From its beginnings in the 1960s, writing software has evolved into a profession concerned with how best to maximize the quality of software and of how to create it. Quality can refer to how maintainable software is, to its stability, speed, usability, testability, readability, size, cost, security, and number of flaws or "bugs", as well as to less measurable qualities like elegance, conciseness, and customer satisfaction, among many other attributes. How best to create high quality software is a separate and controversial problem covering software design principles, so-called "best practices" for writing code, as well as broader management issues such as optimal team size, process, how best to deliver software on time and as quickly as possible, work-place "culture", hiring practices, and so forth. All this falls under the broad rubric of software engineering.

🔗 Yakhchāl
Yakhchāl (Persian: یخچال "ice pit"; yakh meaning "ice" and chāl meaning "pit") is an ancient type of evaporative cooler. Above ground, the structure had a domed shape, but had a subterranean storage space. It was often used to store ice, but sometimes was used to store food as well. The subterranean space coupled with the thick heat-resistant construction material insulated the storage space year round. These structures were mainly built and used in Persia. Many that were built hundreds of years ago remain standing.
