The Groom of the Stool (formally styled: "Groom of the King's Close Stool") was the most intimate of an English monarch's courtiers, responsible for assisting the king in excretion and ablution.

The physical intimacy of the role naturally led to his becoming a man in whom much confidence was placed by his royal master and with whom many royal secrets were shared as a matter of course. This secret information—while it would never have been revealed, for it would have led to the discredit of his honour—in turn led to his becoming feared and respected and therefore powerful within the royal court in his own right. The office developed gradually over decades and centuries into one of administration of the royal finances, and under Henry VII, the Groom of the Stool became a powerful official involved in setting national fiscal policy, under the "chamber system".

Later, the office was renamed Groom of the Stole. The Tudor historian David Starkey classes this change as classic Victorianism: "When the Victorians came to look at this office, they spelt it s-t-o-l-e, and imagined all kinds of fictions about elaborate robes draped around the neck of the monarch at the coronation;" however, the change is in fact seen as early as the 17th century.

Commonplace books (or commonplaces) are a way to compile knowledge, usually by writing information into books. They have been kept from antiquity, and were kept particularly during the Renaissance and in the nineteenth century. Such books are essentially scrapbooks filled with items of every kind: recipes, quotes, letters, poems, tables of weights and measures, proverbs, prayers, legal formulas. Commonplaces are used by readers, writers, students, and scholars as an aid for remembering useful concepts or facts. Each one is unique to its creator's particular interests but they almost always include passages found in other texts, sometimes accompanied by the compiler's responses. They became significant in Early Modern Europe.

"Commonplace" is a translation of the Latin term locus communis (from Greek tópos koinós, see literary topos) which means "a general or common topic", such as a statement of proverbial wisdom. In this original sense, commonplace books were collections of such sayings, such as John Milton's example. Scholars now understand them to include manuscripts in which an individual collects material which have a common theme, such as ethics, or exploring several themes in one volume. Commonplace books are private collections of information, but they are not diaries or travelogues.

In 1685 the English Enlightenment philosopher John Locke wrote a treatise in French on commonplace books, translated into English in 1706 as A New Method of Making Common-Place-Books, "in which techniques for entering proverbs, quotations, ideas, speeches were formulated. Locke gave specific advice on how to arrange material by subject and category, using such key topics as love, politics, or religion. Commonplace books, it must be stressed, are not journals, which are chronological and introspective."

By the early eighteenth century they had become an information management device in which a note-taker stored quotations, observations and definitions. They were used in private households to collate ethical or informative texts, sometimes alongside recipes or medical formulae. For women, who were excluded from formal higher education, the commonplace book could be a repository of intellectual references. The gentlewoman Elizabeth Lyttelton kept one from the 1670s to 1713 and a typical example was published by Mrs Anna Jameson in 1855, including headings such as Ethical Fragments; Theological; Literature and Art. Commonplace books were used by scientists and other thinkers in the same way that a database might now be used: Carl Linnaeus, for instance, used commonplacing techniques to invent and arrange the nomenclature of his Systema Naturae (which is the basis for the system used by scientists today). The commonplace book was often a lifelong habit: for example the English-Australian artist Georgina McCrae kept a commonplace book from 1828-1865.

Degrowth (French: décroissance) is a political, economic, and social movement based on ecological economics, anti-consumerist and anti-capitalist ideas. It is also considered an essential economic strategy responding to the limits-to-growth dilemma (see The Path to Degrowth in Overdeveloped Countries and post-growth). Degrowth thinkers and activists advocate for the downscaling of production and consumption – the contraction of economies – arguing that overconsumption lies at the root of long term environmental issues and social inequalities. Key to the concept of degrowth is that reducing consumption does not require individual martyring or a decrease in well-being. Rather, "degrowthers" aim to maximize happiness and well-being through non-consumptive means—sharing work, consuming less, while devoting more time to art, music, family, nature, culture and community.

Gregory F. Packer (born December 18, 1963), is a retired American highway maintenance worker from Huntington, New York, best known for frequently being quoted as a "man on the street" in newspapers, magazines and television broadcasts from 1995 to the present. He has been quoted in hundreds of articles and television broadcasts as a member of the public (that is, a "man on the street" rather than a newsmaker or expert). Although he always gives his real name, he has admitted to making things up to get into the paper.

Packer's status as a frequent interviewee is due to a number of factors, including seeking out members of the press and appearing friendly, although mostly it is due to his hobby of attending public appearances of celebrities and other media events and attempting to be first in line on such occasions. This has led to him being dubbed a professional line sitter. It has also led to Packer's other claim to fame: being the first person in the world to buy an iPhone, on June 29, 2007 at Apple Fifth Avenue in New York City, after having camped out for five days in front of the store. (He tried to similarly be the first to buy an iPad in 2010, but was bumped from the first position in line due to not having a reservation.) His efforts to be first in line have also allowed him to meet people including Mariah Carey, Garth Brooks, Dennis Rodman and Ringo Starr, as well as at least four presidents of the United States: Jimmy Carter, Bill Clinton, George W. Bush and (before he became president) Donald Trump.

50 Cent Party, 50 Cent Army and wumao ( WOO-mow) are terms for Internet commentators who are hired by the authorities of the People's Republic of China to manipulate public opinion and disseminate disinformation to the benefit of the governing Chinese Communist Party (CCP). It was created during the early phases of the Internet's rollout to the wider public in China.

The name is derived from the allegation that such commentators are paid RMB¥0.50 for every post. These commentators create comments or articles on popular Chinese social media networks that are intended to derail discussions which are critical of the CCP, promoting narratives that serve the government's interests and insulting or spreading misinformation about political opponents of the Chinese government, both domestic and abroad. Some of these commentators have labeled themselves ziganwu (Chinese: 自干五, short for 自带干粮的五毛, lit. 'wumao who bring their own dry rations'), claiming they are not paid by authorities and express their support for the Chinese government out of their own volition.

Authors of a paper published in 2017 in the American Political Science Review estimate that the Chinese government fabricates 488 million social media posts per year. In contrast to common assumptions, the 50 Cent Party consists mostly of paid bureaucrats who respond to government directives and rarely defend their government from criticism or engage in direct arguments because "... the goal of this massive secretive operation is instead to distract the public and change the subject." Around 80% of the analysed posts involve pro-China cheerleading with inspirational slogans, and 13% involve general praise and suggestions on governmental policies. Despite the common allegation of the commentators getting paid for their posts, the paper suggested there was "no evidence" that they are paid anything for their posts, instead being required to do so as a part of their official party duties.

Research by professors at Harvard, Stanford, and UC San Diego indicated a "massive secretive operation" to fill China's Internet with propaganda, and has resulted in some 488 million posts written by fake social media accounts, representing about 0.6% of the 80 billion posts generated on Chinese social media. To maximize their influence, such pro-government comments are made largely during times of intense online debate, and when online protests have a possibility of transforming into real life actions. The colloquial term wumao has also been used by some English speakers outside of China as an insult against people with perceived pro-CCP bias.

Zhima Credit (Chinese: 芝麻信用; pinyin: Zhīma Xìnyòng), also known as Sesame Credit, is a private credit scoring and loyalty program system developed by Ant Financial Services Group (AFSG), an affiliate of the Chinese Alibaba Group. It uses data from Alibaba's services to compile its score. Customers receive a score based on a variety of factors based on social media interactions and purchases carried out on Alibaba Group websites or paid for using its affiliate Ant Financial's Alipay mobile wallet. The rewards of having a high score include easier access to loans from Ant Financial and having a more trustworthy profile on e-commerce sites within the Alibaba Group.

A cognitive distortion is an exaggerated or irrational thought pattern involved in the onset and perpetuation of psychopathological states, especially those more influenced by psychosocial factors, such as depression and anxiety. Psychiatrist Aaron T. Beck laid the groundwork for the study of these distortions, and his student David D. Burns continued research on the topic. Burns, in Feeling Good the new Mood Therapy , described personal and professional anecdotes related to cognitive distortions and their elimination.

Cognitive distortions are thoughts that cause individuals to perceive reality inaccurately. According to the cognitive model of Beck, a negative outlook on reality, sometimes called negative schemas (or schemata), is a factor in symptoms of emotional dysfunction and poorer subjective well-being. Specifically, negative thinking patterns reinforce negative emotions and thoughts. During difficult circumstances, these distorted thoughts can contribute to an overall negative outlook on the world and a depressive or anxious mental state.

Challenging and changing cognitive distortions is a key element of cognitive behavioral therapy (CBT).

In Marxist theory, the Lumpenproletariat (German: [ˈlʊmpn̩pʁoletaʁi̯ˌaːt] ; ) is the underclass devoid of class consciousness. Karl Marx and Friedrich Engels coined the word in the 1840s and used it to refer to the unthinking lower strata of society exploited by reactionary and counter-revolutionary forces, particularly in the context of the revolutions of 1848. They dismissed the revolutionary potential of the Lumpenproletariat and contrasted it with the proletariat. Among other groups, criminals, vagabonds, and prostitutes are usually included in this category.

The Social Democratic Party of Germany made wide use of the term by the turn of the 20th century. Vladimir Lenin and Leon Trotsky followed Marx's arguments and dismissed the group's revolutionary potential, while Mao Zedong argued that proper leadership could harness it. The word Lumpenproletariat, popularized in the West by Frantz Fanon's The Wretched of the Earth in the 1960s, has been adopted as a sociological term. However, what some consider to be its vagueness and its history as a term of abuse has led to some criticism. Some revolutionary groups, most notably the Black Panther Party and the Young Lords, have sought to mobilize the Lumpenproletariat.

A stanhope or stanho-scope is an optical device that enables the viewing of microphotographs without using a microscope. They were invented by René Dagron in 1857. Dagron bypassed the need for an expensive microscope to view the microscopic photographs by attaching the microphotograph at the end of a modified Stanhope lens. He called the devices bijoux photo-microscopiques or microscopic photo-jewelry.

Jazelle DBX (direct bytecode execution) is an extension that allows some ARM processors to execute Java bytecode in hardware as a third execution state alongside the existing ARM and Thumb modes. Jazelle functionality was specified in the ARMv5TEJ architecture and the first processor with Jazelle technology was the ARM926EJ-S. Jazelle is denoted by a "J" appended to the CPU name, except for post-v5 cores where it is required (albeit only in trivial form) for architecture conformance.

Jazelle RCT (Runtime Compilation Target) is a different technology based on ThumbEE mode; it supports ahead-of-time (AOT) and just-in-time (JIT) compilation with Java and other execution environments.

The most prominent use of Jazelle DBX is by manufacturers of mobile phones to increase the execution speed of Java ME games and applications. A Jazelle-aware Java virtual machine (JVM) will attempt to run Java bytecode in hardware, while returning to the software for more complicated, or lesser-used bytecode operations. ARM claims that approximately 95% of bytecode in typical program usage ends up being directly processed in the hardware.

The published specifications are very incomplete, being only sufficient for writing operating system code that can support a JVM that uses Jazelle. The declared intent is that only the JVM software needs to (or is allowed to) depend on the hardware interface details. This tight binding facilitates the hardware and JVM evolving together without affecting other software. In effect, this gives ARM Holdings considerable control over which JVMs are able to exploit Jazelle. It also prevents open source JVMs from using Jazelle. These issues do not apply to the ARMv7 ThumbEE environment, the nominal successor to Jazelle DBX.
