Vector 2022 is a desktop skin developed between 2019 and 2023 by the Wikimedia Foundation Web team with the goal of making the interface more welcoming and usable for readers and maintaining utility for existing editors.

It introduces changes to the navigation and layout of the site, adds persistent elements such as a sticky header and Table of Contents, and makes changes to the overall styling of the page. Currently (early January 2023), the skin is the default on more than 300 projects of various sizes, accounting for about 1.5 billion page views per month. Before the deployment, on English Wikipedia, it was the most popular non-default skin, with more active editors using it than any other non-default skin (Monobook, Timeless, etc).

The skin was ready for deployment to English Wikipedia after completing the changes specified by the consensus of the Request for Comment. Today (January 18, 2023), the skin was turned on as the default on the desktop site. Users of non-default skins (Monobook, Timeless, etc.) will not see any changes.

If you decide to try it out, we, the Web team, suggest trying it for at least one week prior to deciding whether to switch to one of our older skins. It usually takes a few days to begin feeling comfortable with the new interface. That said, if you are unsatisfied, you can switch to any of our other skins at any time.

In programming language theory and proof theory, the Curry–Howard correspondence (also known as the Curry–Howard isomorphism or equivalence, or the proofs-as-programs and propositions- or formulae-as-types interpretation) is the direct relationship between computer programs and mathematical proofs.

It is a generalization of a syntactic analogy between systems of formal logic and computational calculi that was first discovered by the American mathematician Haskell Curry and logician William Alvin Howard. It is the link between logic and computation that is usually attributed to Curry and Howard, although the idea is related to the operational interpretation of intuitionistic logic given in various formulations by L. E. J. Brouwer, Arend Heyting and Andrey Kolmogorov (see Brouwer–Heyting–Kolmogorov interpretation) and Stephen Kleene (see Realizability). The relationship has been extended to include category theory as the three-way Curry–Howard–Lambek correspondence.

Hitsuzendō (筆禅道, "way of Zen through brush") is believed by Zen Buddhists to be a method of achieving samādhi (Japanese: 三昧 sanmai), which is a unification with the highest reality. Hitsuzendo refers specifically to a school of Japanese Zen calligraphy to which the rating system of modern calligraphy (well-proportioned and pleasing to the eye) is foreign. Instead, the calligraphy of Hitsuzendo must breathe with the vitality of eternal experience.

The Satanic panic is a moral panic consisting of over 12,000 unsubstantiated cases of Satanic ritual abuse (SRA, sometimes known as ritual abuse, ritualistic abuse, organized abuse, or sadistic ritual abuse) starting in the United States in the 1980s, spreading throughout many parts of the world by the late 1990s, and persisting today. The panic originated in 1980 with the publication of Michelle Remembers, a book co-written by Canadian psychiatrist Lawrence Pazder and his patient (and future wife), Michelle Smith, which used the discredited practice of recovered-memory therapy to make sweeping lurid claims about satanic ritual abuse involving Smith. The allegations, which afterwards arose throughout much of the United States, involved reports of physical and sexual abuse of people in the context of occult or Satanic rituals. In its most extreme form, allegations involve a conspiracy of a global Satanic cult that includes the wealthy and elite in which children are abducted or bred for human sacrifices, pornography, and prostitution.

Nearly every aspect of the ritual abuse is controversial, including its definition, the source of the allegations and proof thereof, testimonies of alleged victims, and court cases involving the allegations and criminal investigations. The panic affected lawyers, therapists, and social workers who handled allegations of child sexual abuse. Allegations initially brought together widely dissimilar groups, including religious fundamentalists, police investigators, child advocates, therapists, and clients in psychotherapy. The term satanic abuse was more common early on; this later became satanic ritual abuse and further secularized into simply ritual abuse. Over time, the accusations became more closely associated with dissociative identity disorder (then called multiple personality disorder) and anti-government conspiracy theories.

Initial interest arose via the publicity campaign for Pazder's 1980 book Michelle Remembers, and it was sustained and popularized throughout the decade by coverage of the McMartin preschool trial. Testimonials, symptom lists, rumors, and techniques to investigate or uncover memories of SRA were disseminated through professional, popular, and religious conferences as well as through talk shows, sustaining and further spreading the moral panic throughout the United States and beyond. In some cases, allegations resulted in criminal trials with varying results; after seven years in court, the McMartin trial resulted in no convictions for any of the accused, while other cases resulted in lengthy sentences, some of which were later reversed. Scholarly interest in the topic slowly built, eventually resulting in the conclusion that the phenomenon was a moral panic, which, as one researcher put it in 2017, "involved hundreds of accusations that devil-worshipping paedophiles were operating America's white middle-class suburban daycare centers."

Of the more than 12,000 documented accusations nationwide, investigating police were not able to substantiate any allegations of organized cult abuse.

The Bogle–Chandler case refers to the mysterious deaths of Gilbert Bogle and Margaret Chandler on the banks of the Lane Cove River in Sydney, Australia on 1 January 1963. The case became famous because of the circumstances in which the bodies were found and because the cause of death could not be established. In 2006 a filmmaker discovered evidence to suggest the cause of death was hydrogen sulphide gas. In the early hours of 1 January an eruption of gas from the polluted river bed may have occurred, causing the noxious fumes to pool in deadly quantities in the grove.

🔗 Judaism

Tza'ar ba'alei chayim (Hebrew: צער בעלי חיים‎), literally "suffering of living creatures", is a Jewish commandment which bans causing animals unnecessary suffering. This concept is not clearly enunciated in the written Torah, but was accepted by the Talmud as being a biblical mandate. It is linked in the Talmud from the biblical law requiring people to assist in unloading burdens from animals (Exodus 23:5).

🔗 Elements

Alternative periodic tables are tabulations of chemical elements differing in their organization from the traditional depiction of the periodic system.

Over a thousand have been devised, often for didactic reasons, as not all correlations between the chemical elements are effectively captured by the standard periodic table.

The St. Petersburg paradox or St. Petersburg lottery is a paradox related to probability and decision theory in economics. It is based on a particular (theoretical) lottery game that leads to a random variable with infinite expected value (i.e., infinite expected payoff) but nevertheless seems to be worth only a very small amount to the participants. The St. Petersburg paradox is a situation where a naive decision criterion which takes only the expected value into account predicts a course of action that presumably no actual person would be willing to take. Several resolutions are possible.

The paradox takes its name from its resolution by Daniel Bernoulli, one-time resident of the eponymous Russian city, who published his arguments in the Commentaries of the Imperial Academy of Science of Saint Petersburg (Bernoulli 1738). However, the problem was invented by Daniel's cousin, Nicolas Bernoulli, who first stated it in a letter to Pierre Raymond de Montmort on September 9, 1713 (de Montmort 1713).

The Unix philosophy, originated by Ken Thompson, is a set of cultural norms and philosophical approaches to minimalist, modular software development. It is based on the experience of leading developers of the Unix operating system. Early Unix developers were important in bringing the concepts of modularity and reusability into software engineering practice, spawning a "software tools" movement. Over time, the leading developers of Unix (and programs that ran on it) established a set of cultural norms for developing software; these norms became as important and influential as the technology of Unix itself; this has been termed the "Unix philosophy."

The Unix philosophy emphasizes building simple, short, clear, modular, and extensible code that can be easily maintained and repurposed by developers other than its creators. The Unix philosophy favors composability as opposed to monolithic design.

🔗 Musical Instruments 🔗 Electronic music

The Ondioline is an electronic keyboard instrument, invented in 1941 by the Frenchman Georges Jenny, and is a forerunner of today's synthesizers. It is sometimes called the "Jenny Ondioline."

The Ondioline is capable of creating a wide variety of sounds. Its keyboard has an unusual feature: it is suspended on special springs which makes it possible to introduce a natural vibrato if the player moves the keyboard (not the entire instrument) from side to side (laterally) with their playing hand. The result is an almost human-like vibrato that lends a wide range of expression to the Ondioline. The keyboard is also pressure-sensitive, and the instrument has a knee volume lever, as well.
