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.

🔗 Germany 🔗 Trains 🔗 Trains/Rail transport in Germany

The Breitspurbahn (German pronunciation: [ˈbʁaɪtʃpuːɐ̯baːn], transl. broad-gauge railway) was a railway system planned and partly surveyed by Nazi Germany. Its track gauge – the distance between the two running rails – was to be 3000 mm (9 ft 10+1⁄8 in), more than twice that of the 1435 mm (4 ft 8+1⁄2 in) standard gauge used in western Europe. The railway was intended initially to run between major cities of the Greater Germanic Reich (the regime's expanded Germany) and neighbouring states.

🔗 Economics 🔗 Education 🔗 Game theory 🔗 Games

A simulation game is "a game that contains a mixture of skill, chance, and strategy to simulate an aspect of reality, such as a stock exchange". Similarly, Finnish author Virpi Ruohomäki states that "a simulation game combines the features of a game (competition, cooperation, rules, participants, roles) with those of a simulation (incorporation of critical features of reality). A game is a simulation game if its rules refer to an empirical model of reality". A properly built simulation game used to teach or learn economics would closely follow the assumptions and rules of the theoretical models within this discipline.

Sousveillance ( soo-VAY-lənss) is the recording of an activity by a participant in the activity, typically by way of small wearable or portable personal technologies. The term "sousveillance", coined by Steve Mann, stems from the contrasting French words sur, meaning "above", and sous, meaning "below", i.e. "surveillance" denotes the "eye-in-the-sky" watching from above, whereas "sousveillance" denotes bringing the camera or other means of observation down to human level, either physically (mounting cameras on people rather than on buildings), or hierarchically (ordinary people doing the watching, rather than higher authorities or architectures doing the watching).

While surveillance and sousveillance both generally refer to visual monitoring, the terms also denote other forms of monitoring such as audio surveillance or sousveillance. In the audio sense (e.g. recording of phone conversations), sousveillance is referred to as "one party consent".

Undersight (inverse oversight) is sousveillance at high-level, e.g. "citizen undersight" being reciprocal to a congressional oversight committee or the like.

Inverse surveillance is a subset of sousveillance with a particular emphasis on the "watchful vigilance from underneath" and a form of surveillance inquiry or legal protection involving the recording, monitoring, study, or analysis of surveillance systems, proponents of surveillance, and possibly also recordings of authority figures and their actions. Inverse surveillance is typically an activity undertaken by those who are generally the subject of surveillance, and may thus be thought of as a form of an ethnography or ethnomethodology study (i.e. an analysis of the surveilled from the perspective of a participant in a society under surveillance).

Sousveillance typically involves community-based recording from first person perspectives, without necessarily involving any specific political agenda, whereas inverse-surveillance is a form of sousveillance that is typically directed at, or used to collect data to analyze or study, surveillance or its proponents (e.g., the actions of police or protestors at a protest rally).

Sousveillance is not necessarily countersurveillance; i.e. sousveillance can be used to "counter" the forces of surveillance, or it can also be used together with surveillance to create a more complete "veillance" ("Surveillance is a half-truth without sousveillance"). The question of "Who watches the watchers" is dealt with more properly under the topic of metaveillance (the veillance of veillance) than sousveillance.

Add A Fact is a temporary experimental tool created by the Wikimedia Foundation's Future Audience team to learn how and if we can support making it possible to contribute productively to Wikipedia from outside of Wikipedia, and if guidance to the contributor from a large language model (LLM) could be useful in this process. The idea was developed and workshopped with Wikipedians at WikiConference North America 2023, demoed and tested with Wikipedia community members as part of our team’s regular monthly community calls.

Add A Fact is available for the Google Chrome and Mozilla Firefox browsers and can be used by any logged in, autoconfirmed English Wikipedia user. We welcome your feedback on the talk page of this page, or via the Feedback tool in the browser extension.

🔗 Computing 🔗 Computer science

In functional programming, continuation-passing style (CPS) is a style of programming in which control is passed explicitly in the form of a continuation. This is contrasted with direct style, which is the usual style of programming. Gerald Jay Sussman and Guy L. Steele, Jr. coined the phrase in AI Memo 349 (1975), which sets out the first version of the Scheme programming language.John C. Reynolds gives a detailed account of the numerous discoveries of continuations.

A function written in continuation-passing style takes an extra argument: an explicit "continuation"; i.e., a function of one argument. When the CPS function has computed its result value, it "returns" it by calling the continuation function with this value as the argument. That means that when invoking a CPS function, the calling function is required to supply a procedure to be invoked with the subroutine's "return" value. Expressing code in this form makes a number of things explicit which are implicit in direct style. These include: procedure returns, which become apparent as calls to a continuation; intermediate values, which are all given names; order of argument evaluation, which is made explicit; and tail calls, which simply call a procedure with the same continuation, unmodified, that was passed to the caller.

Programs can be automatically transformed from direct style to CPS. Functional and logic compilers often use CPS as an intermediate representation where a compiler for an imperative or procedural programming language would use static single assignment form (SSA). SSA is formally equivalent to a subset of CPS (excluding non-local control flow, which does not occur when CPS is used as intermediate representation). Functional compilers can also use A-normal form (ANF) (but only for languages requiring eager evaluation), rather than with 'thunks' (described in the examples below) in CPS. CPS is used more frequently by compilers than by programmers as a local or global style.

🔗 Biography 🔗 Psychology 🔗 Biography/science and academia

Edwin Ray Guthrie (; January 9, 1886 in Lincoln, Nebraska – April 23, 1959 in Seattle, Washington) was a behavioral psychologist. He first worked as a mathematics teacher, and philosopher, but switched to psychology when he was 33. He spent most of his career at the University of Washington, where he became full professor and then emeritus professor in psychology.

Guthrie is best known for his theory that all learning was based on a stimulus–response association. This was variously described as one trial theory, non-reinforcement, and contiguity learning. The theory was:

"A combination of stimuli which has accompanied a movement will on its recurrence tend to be followed by that movement".

One word that his coworkers and students used to describe Guthrie and his theories was "simple", and perhaps he did prefer to use simple terms to illustrate complex ideas. However, "It is undoubtedly true that many reviews of Guthrie in the literature have mistaken incompleteness for simplicity".

His simple nature carried into his teachings where he took great pride in working with and teaching students.

DBOS is a Database-Oriented Operating System designed to simplify and improve the scalability, security and resilience of large-scale distributed applications. It started in 2020 as a joint open source project with MIT, Stanford and Carnegie Mellon University, after a brainstorm between Michael Stonebraker and Matei Zaharia on how to scale and improve scheduling and performance of millions of Apache Spark tasks.

The basic idea is to run a multi-node multi-core, transactional, highly-available distributed database, such as VoltDB, as the only application for a microkernel, and then to implement scheduling, messaging, file systems and other operating system services on top of the database.

The architectural philosophy is described by this quote from the abstract of their initial preprint:

All operating system state should be represented uniformly as database tables, and operations on this state should be made via queries from otherwise stateless tasks. This design makes it easy to scale and evolve the OS without whole-system refactoring, inspect and debug system state, upgrade components without downtime, manage decisions using machine learning, and implement sophisticated security features.

Stonebraker claims a variety of security benefits, from a "smaller, less porous attack surface", to the ability to log and analyze how the system state changes in real-time due to the transactional nature of the OS. Recovery from a severe bug or an attack can be as simple as rolling back the database to a previous state. And since the database is already distributed, the complexity of orchestration systems like Kubernetes can be avoided.

A prototype was built with competitive performance to existing systems.

🔗 Internet culture 🔗 Sociology

An edgelord is someone on the Internet who tries to impress or shock by posting edgy opinions such as nihilism or extremist views.

The term is a portmanteau derived from "edgy" and "shitlord" – a person who "basks in the bitterness and misery of others".

Merriam-Webster gave the following example:

We decided to watch It's A Wonderful Life and my dad said, “Every year I wait for Jimmy Stewart to jump off that bridge but he never does it” - merry Xmas from the original edgelord.

Edgelords were characterised by author Rachel Monroe in her account of criminal behaviour, Savage Appetites:

...internet cynics lumped the online Nazis together with the serial killer fetishists and the dumbest goths and dismissed them all as edgelords: kids who tried to be scary online. I thought of most of these edgelords as basement-dwellers, pale faces lit by the glow of their computer screen, puffing themselves up with nihilism. An edgelord was a scrawny guy with a LARP-y vibe, possibly wearing a cloak, dreaming of omnipotence. Or a girl with excessive eyeliner and lots of Tumblr posts about self-harm. The disturbing content posted by edgelords was undermined by its predictability...

It is frequently associated with the forum site 4chan.

Wootz steel is a crucible steel characterized by a pattern of bands. These bands are formed by sheets of microscopic carbides within a tempered martensite or pearlite matrix in higher carbon steel, or by ferrite and pearlite banding in lower carbon steels. It was a pioneering steel alloy developed in Southern India (Tamilakam present day Tamil Nadu and Kerala) and Sri Lanka in the 6th century BC and exported globally. It was also known in the ancient world by many different names including ukku, Hindvi steel, Hinduwani steel, Teling steel and seric iron.
