Mainline DHT is the name given to the Kademlia-based Distributed Hash Table (DHT) used by BitTorrent clients to find peers via the BitTorrent protocol. The idea of utilizing a DHT for distributed tracking was first implemented in Azureus 2.3.0.0 (now known as Vuze) in May 2005, from which it gained significant popularity. Unrelated but similarly timed BitTorrent, Inc. released their own similar DHT into their client, called Mainline DHT and thus popularized the use of distributed tracking in the BitTorrent Protocol. Measurement shows by 2013 users of Mainline DHT is from 10 million to 25 million, with a daily churn of at least 10 million.

The tall poppy syndrome is the cultural phenomenon of jealous people holding back or directly attacking those who are perceived to be better than the norm, "cutting down the tall poppy". It describes a draw towards mediocrity.

Commonly in Australia and New Zealand, "Cutting down the tall poppy" is used to describe those who think too highly of themselves and it is seen by some as self-deprecating and by others as promoting modesty and egalitarianism.

"The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information" is one of the most highly cited papers in psychology. It was published in 1956 in Psychological Review by the cognitive psychologist George A. Miller of Harvard University's Department of Psychology. It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2. This has occasionally been referred to as Miller's law.

Musaeum Clausum (Latin for Sealed Museum), also known as Bibliotheca abscondita, is a tract written by Sir Thomas Browne which was first published posthumously in 1684. The tract contains short sentence descriptions of supposed, rumoured or lost books, pictures, and objects. The subtitle describes the tract as an inventory of remarkable books, antiquities, pictures and rarities of several kinds, scarce or never seen by any man now living. Its date is unknown: however, an event from the year 1673 is cited.

Like his Pseudodoxia Epidemica, Musaeum Clausum is a catalogue of doubts and queries, only this time, in a style which anticipates the 20th-century Argentinian short-story writer Jorge Luis Borges, who once declared: "To write vast books is a laborious nonsense; much better is to offer a summary as if those books actually existed."

Browne however was not the first author to engage in such fantasy. The French author Rabelais, in his epic Gargantua and Pantagruel, also penned a list of imaginary and often obscene book titles in his "Library of Pantagruel", an inventory which Browne himself alludes to in his Religio Medici.

As the 17th-century Scientific Revolution progressed the popularity and growth of antiquarian collections, those claiming to house highly improbable items grew. Browne was an avid collector of antiquities and natural specimens, possessing a supposed unicorn's horn, presented to him by Arthur Dee. Browne's eldest son Edward visited the famous scholar Athanasius Kircher, founder of the Museo Kircherano at Rome in 1667, whose exhibits included an engine for attempting perpetual motion and a speaking head, which Kircher called his Oraculum Delphinium. He wrote to his father of his visit to the Jesuit priest's "closet of rarities".

The sheer volume of book-titles, pictures and objects listed in Musaeum Clausum is testimony to Browne's fertile imagination. However, his major editors, Simon Wilkin in the nineteenth century (1834) and Sir Geoffrey Keynes in the twentieth (1924), summarily dismissed it. Keynes considered its humour too erudite and "not to everyone's taste".

Browne's miscellaneous tract may also be read as a parody of the rising trend of private museum collections with their curios of doubtful origin, and perhaps also of publications such as the so-called Museum Hermeticum (1678), one of the last great anthologies of alchemical literature, with their divulging of near common-place alchemical concepts and symbols.

The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly 2 million years.

The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier.

🔗 Economics

The Penn effect is the economic finding that real income ratios between high and low income countries are systematically exaggerated by gross domestic product (GDP) conversion at market exchange rates. It is associated with what became the Penn World Table, and it has been a consistent econometric result since at least the 1950s.

The "Balassa–Samuelson effect" is a model cited as the principal cause of the Penn effect by neo-classical economics, as well as being a synonym of "Penn effect".

Edward Louis Bernays (; German: [bɛɐ̯ˈnaɪs]; November 22, 1891 − March 9, 1995) was an Austrian-American pioneer in the field of public relations and propaganda, referred to in his obituary as "the father of public relations". Bernays was named one of the 100 most influential Americans of the 20th century by Life. He was the subject of a full length biography by Larry Tye called The Father of Spin (1999) and later an award-winning 2002 documentary for the BBC by Adam Curtis called The Century of the Self.

His best-known campaigns include a 1929 effort to promote female smoking by branding cigarettes as feminist "Torches of Freedom" and his work for the United Fruit Company connected with the CIA-orchestrated overthrow of the democratically elected Guatemalan government in 1954. He worked for dozens of major American corporations including Procter & Gamble and General Electric, and for government agencies, politicians, and non-profit organizations.

Of his many books, Crystallizing Public Opinion (1923) and Propaganda (1928) gained special attention as early efforts to define and theorize the field of public relations. Citing works of writers such as Gustave Le Bon, Wilfred Trotter, Walter Lippmann, and his own double uncle Sigmund Freud, he described the masses as irrational and subject to herd instinct—and outlined how skilled practitioners could use crowd psychology and psychoanalysis to control them in desirable ways.

Linguistic purism in English is the preference for using words of native origin rather than foreign-derived ones. "Native" can mean "Anglo-Saxon" or it can be widened to include all Germanic words. Linguistic purism in English primarily focuses on words of Latinate and Greek origin, due to their prominence in the English language and the belief that they may be difficult to understand. In its mildest form, it merely means using existing native words instead of foreign-derived ones (such as using begin instead of commence). In a less mild form, it also involves coining new words from Germanic roots (such as wordstock for vocabulary). In a more extreme form, it also involves reviving native words which are no longer widely used (such as ettle for intend). The resulting language is sometimes called Anglish (coined by the author and humorist Paul Jennings), or Roots English (referring to the idea that it is a "return to the roots" of English). The mild form is often advocated as part of Plain English, but the more extreme form has been and is still a fringe movement; the latter can also be undertaken as a form of constrained writing.

English linguistic purism is discussed by David Crystal in the Cambridge Encyclopedia of the English Language. The idea dates at least to the inkhorn term controversy of the 16th and 17th centuries. In the 19th century, writers such as Charles Dickens, Thomas Hardy and William Barnes advocated linguistic purism and tried to introduce words like birdlore for ornithology and bendsome for flexible. A notable supporter in the 20th century was George Orwell, who had a preference for plain Saxon words over complex Latin or Greek ones, and the idea continues to have advocates today.
