In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate a very long string. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done efficiently.

A self-replicating machine is a type of autonomous robot that is capable of reproducing itself autonomously using raw materials found in the environment, thus exhibiting self-replication in a way analogous to that found in nature. Such machines are often featured in works of science fiction.

The Hajnal line is a border that links Saint Petersburg, Russia and Trieste, Italy. In 1965, John Hajnal discovered it divides Europe into two areas characterized by different levels of nuptiality. To the west of the line, marriage rates and thus fertility were comparatively low and a significant minority of women married late or remained single; to the east of the line and in the Mediterranean and select pockets of Northwestern Europe, early marriage was the norm and high fertility was countered by high mortality.

Zaum (Russian: за́умь, lit. 'transrational') are the linguistic experiments in sound symbolism and language creation of Russian Cubo-Futurist poets such as Velimir Khlebnikov and Aleksei Kruchenykh. Zaum is a non-referential phonetic entity with its own ontology. The language consists of neologisms that mean nothing. Zaum is a language organized through phonetic analogy and rhythm. Zaum literature cannot contain any onomatopoeia or psychopathological states.

Unlambda is a minimal, "nearly pure" functional programming language invented by David Madore. It is based on combinatory logic, an expression system without the lambda operator or free variables. It relies mainly on two built-in functions (s and k) and an apply operator (written `, the backquote character). These alone make it Turing-complete, but there are also some input/output (I/O) functions to enable interacting with the user, some shortcut functions, and a lazy evaluation function. Variables are unsupported.

Unlambda is free and open-source software distributed under a GNU General Public License (GPL) 2.0 or later.

🔗 Physics 🔗 Astronomy

The Chandrasekhar limit () is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M_☉ (2.765×10³⁰ kg).

White dwarfs resist gravitational collapse primarily through electron degeneracy pressure (compare main sequence stars, which resist collapse through thermal pressure). The Chandrasekhar limit is the mass above which electron degeneracy pressure in the star's core is insufficient to balance the star's own gravitational self-attraction. Consequently, a white dwarf with a mass greater than the limit is subject to further gravitational collapse, evolving into a different type of stellar remnant, such as a neutron star or black hole. Those with masses up to the limit remain stable as white dwarfs.

The limit was named after Subrahmanyan Chandrasekhar, an Indian astrophysicist who improved upon the accuracy of the calculation in 1930, at the age of 20, in India by calculating the limit for a polytrope model of a star in hydrostatic equilibrium, and comparing his limit to the earlier limit found by E. C. Stoner for a uniform density star. Importantly, the existence of a limit, based on the conceptual breakthrough of combining relativity with Fermi degeneracy, was indeed first established in separate papers published by Wilhelm Anderson and E. C. Stoner in 1929. The limit was initially ignored by the community of scientists because such a limit would logically require the existence of black holes, which were considered a scientific impossibility at the time. The fact that the roles of Stoner and Anderson are often forgotten in the astronomy community has been noted.

🔗 United States 🔗 Skepticism 🔗 Anthropology

Nacirema ("American" spelled backwards) is a term used in anthropology and sociology in relation to aspects of the behavior and society of citizens of the United States of America. The neologism attempts to create a deliberate sense of self-distancing in order that American anthropologists might look at their own culture more objectively.

In fiction, a MacGuffin (sometimes McGuffin) is an object, device, or event that is necessary to the plot and the motivation of the characters, but insignificant, unimportant, or irrelevant in itself. The term was originated by Angus MacPhail for film, adopted by Alfred Hitchcock, and later extended to a similar device in other fiction.

The MacGuffin technique is common in films, especially thrillers. Usually, the MacGuffin is revealed in the first act, and thereafter declines in importance. It can reappear at the climax of the story but may actually be forgotten by the end of the story. Multiple MacGuffins are sometimes derisively identified as plot coupons.

The emo killings in Iraq were a string of homicides that were part of a campaign against Iraqi teenage boys who dressed in a Westernized emo style. Between 6 and 70 young men were kidnapped, tortured and murdered in Baghdad and Iraq during March 2012. In September 2012, BBC News reported that gay men in Baghdad said the killings had not abated.

The Uyghur genocide is the ongoing series of human rights abuses perpetrated by the government of China against the Uyghur people and other ethnic and religious minorities in and around the Xinjiang Uygur Autonomous Region (XUAR) of the People's Republic of China. Since 2014, the Chinese government, under the direction of the Chinese Communist Party (CCP) during the administration of CCP general secretary Xi Jinping, has pursued policies leading to more than one million Muslims (the majority of them Uyghurs) being held in secretive internment camps without any legal process in what has become the largest-scale and most systematic detention of ethnic and religious minorities since the Holocaust and World War II. Thousands of mosques have been destroyed or damaged, and hundreds of thousands of children have been forcibly separated from their parents and sent to boarding schools.

These policies have been described by critics as the forced assimilation of Xinjiang, as well as an ethnocide or cultural genocide. Some governments, activists, independent NGOs, human rights experts, academics, government officials, and the East Turkistan Government-in-Exile have called it a genocide.

In particular, critics have highlighted the concentration of Uyghurs in state-sponsored internment camps, suppression of Uyghur religious practices, political indoctrination, severe ill-treatment, as well as extensive evidence and other testimonials detailing human rights abuses including forced sterilization, contraception, abortion, and infanticides. Chinese government statistics show that from 2015 to 2018, birth rates in the mostly Uyghur regions of Hotan and Kashgar fell by more than 60%. In the same period, the birth rate of the whole country decreased by 9.69%, from 12.07 to 10.9 per 1,000 people. Chinese authorities acknowledged that birth rates dropped by almost a third in 2018 in Xinjiang, but denied reports of forced sterilization and genocide. Birth rates fell nearly 24% in 2019 (compared to a nationwide decrease of just 4.2%).

International reactions have been sharply divided, with dozens of United Nations (UN) member states issuing opposing letters to the United Nations Human Rights Council in support and condemnation of China's policies in Xinjiang in 2020. In December 2020, the International Criminal Court declined to take investigative action against China on the basis of not having jurisdiction over China for most of the alleged crimes. The United States was the first country to declare the human rights abuses a genocide, announcing its determination on January 19, 2021, although the US State Department's Office of the Legal Adviser concluded that there was insufficient evidence to prove genocide. This was followed by Canada's House of Commons and the Dutch parliament each passing a non-binding motion in February 2021 to recognize China's actions as genocide. Later, in April 2021, the United Kingdom's House of Commons unanimously passed a non-binding motion to recognize the actions as genocide. In May 2021 the New Zealand parliament unanimously declared that "severe human rights abuses" were occurring against the Uyghur people in China and the Seimas of Lithuania passed a resolution that recognized the Chinese government's abuse of the Uyghurs as a genocide.
