π K-219
K-219 was a Project 667A Navaga-class ballistic missile submarine (NATO reporting name Yankee I) of the Soviet Navy. It carried 16 R-27U liquid-fuel missiles powered by UDMH with nitrogen tetroxide (NTO), and equipped with either 32 or 48 nuclear warheads.K-219 was involved in what has become one of the most controversial submarine incidents during the Cold War on Friday 3 October 1986. The 15-year-old vessel, which was on an otherwise routine Cold War nuclear deterrence patrol in the North Atlantic 1,090 kilometres (680Β mi) northeast of Bermuda, suffered an explosion and fire in a missile tube. While underway submerged the seal in a missile hatch cover failed, allowing high-pressure seawater to enter the missile tube and owing to the pressure differential rupture the missile fuel tanks, allowing missile's liquid fuel to mix and ultimately combust. Though there was no official announcement, the Soviet Union claimed the leak was caused by a collision with the submarine USSΒ Augusta. Although Augusta was operating within the area, both the United States Navy and the commander of K-219, Captain Second Rank Igor Britanov, deny that a collision took place.
The incident was novelized in the book Hostile Waters, which reconstructed the incident from descriptions by the survivors, ships' logs, the official investigations, and participants both ashore and afloat from the Soviet and the American sides.

π Flanderization
Flanderization is the process through which a fictional character's essential traits are exaggerated over the course of a serial work. The term flanderization was coined by TV Tropes in reference to Ned Flanders of The Simpsons, who was caricatured over the show's run from a good neighbor who was religious among other characteristics into an evangelical "bible-thumper". Flanderization has been analyzed as an aspect of serial works, especially television comedies, that shows a work's decline.

π Queen Elizabeth II has died
Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 β 8 September 2022) was Queen of the United Kingdom from 6Β February 1952 until her death in 2022. Her reign of 70 years and 214 days was the longest of any British monarch and the second-longest recorded of any monarch of a sovereign country. At the time of her death, Elizabeth was queen of 14 other Commonwealth realms in addition to the UK.
Elizabeth was born in Mayfair, London, as the first child of the Duke and Duchess of York (later King GeorgeΒ VI and Queen Elizabeth). Her father acceded to the throne in 1936 upon the abdication of his brother, King EdwardΒ VIII, making Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince of Greece and Denmark, and their marriage lasted 73 years until his death in April 2021. They had four children together: Charles III; Anne, Princess Royal; Prince Andrew, Duke of York; and Prince Edward, Earl of Wessex.
When her father died in February 1952, Elizabethβthen 25 years oldβbecame queen regnant of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon (known today as Sri Lanka), as well as Head of the Commonwealth. Elizabeth reigned as a constitutional monarch through major political changes such as the Troubles in Northern Ireland, devolution in the United Kingdom, the decolonisation of Africa, and the United Kingdom's accession to the European Communities and withdrawal from the European Union. The number of her realms varied over time as territories have gained independence and some realms have become republics. Her many historic visits and meetings include state visits to China in 1986, Russia in 1994, the Republic of Ireland in 2011, and visits with five Popes.
Significant events include Elizabeth's coronation in 1953 and the celebrations of her Silver, Golden, Diamond, and Platinum Jubilees in 1977, 2002, 2012, and 2022, respectively. Elizabeth was the longest-lived and longest-reigning British monarch, and the second-longest verifiable reigning sovereign monarch in world history, only behind Louis XIV of France. She faced occasional republican sentiment and media criticism of her family, particularly after the breakdowns of her children's marriages, her annus horribilis in 1992, and the death of her former daughter-in-law Diana, Princess of Wales, in 1997. However, support for the monarchy in the United Kingdom remained consistently high, as did her personal popularity. Elizabeth died on 8 September 2022 at Balmoral Castle, Aberdeenshire. She was succeeded by her eldest son, Charles III.

π Black Hours, Morgan MS 493
The Black Hours, MS M.493 (or the Morgan Black Hours) is an illuminated book of hours completed in Bruges between 1460 and 1475. It consists of 121 pages (leaves), with Latin text written in Gothic minuscule script. The words are arranged in rows of fourteen lines and follow the Roman version of the texts. The lettering is inscribed in silver and gold and placed within borders ornamented with flowers, foliage and grotesques, on pages dyed a deep blueish black. It contains fourteen full-page miniatures and opens with the months of the liturgical calendar (folios 3 verso β 14 recto), followed by the Hours of the Virgin, and ends with the Office of the Dead (folio 121v).
MS M.493 has been in the collection of the Morgan Library & Museum, New York, since 1912. It is one of seven surviving black books of hours, all originating from Bruges and dated to the mid-to-late 15th century. They are so named for their unusual dark blueish appearance, a colourisation achieved through the expensive process of dyeing the vellum with iron gall ink. This dye is very corrosive and the surviving examples are mostly badly decomposed; MS M.493 is in relatively good condition due to its very thick parchment.
The book is a masterpiece of Late Gothic manuscript illumination. However, no records survive of its commission, but its uniquely dark tone, expense of production, quality and rarity suggest ownership by privileged and sophisticated members of the Burgundian court. The book is often attributed, on stylistic grounds, to a follower of Willem Vrelant, a leading and influential Flemish illuminator.

π Inco Superstack
The Inco Superstack in Sudbury, Ontario, with a height of 381 metres (1,250Β ft), is the tallest chimney in Canada and the Western hemisphere, and the second tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It is also the second tallest freestanding structure of any type in Canada, behind the CN Tower but ahead of First Canadian Place. It is the 51st tallest freestanding structure in the world. The Superstack is located on top of the largest nickel smelting operation in the world at Vale's Copper Cliff processing facility in the city of Greater Sudbury.
In 2018, Vale announced that the stack would be decommissioned and dismantled beginning in 2020. Two new, smaller stacks were constructed under the company's Clean Atmospheric Emissions Reduction Project. In July 2020, Vale announced that the Superstack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in the event of a malfunction in the new system, following which the dismantling of the Superstack would begin. As of August 2021, however, Vale has not yet announced the awarding of a demolition contract on the Superstack, and it remains unknown when demolition will actually begin.
In addition to further reducing sulphur dioxide emissions by 85 per cent, the decommissioning of the stack is expected to cut the complex's natural gas consumption in half.

π Types of Prostitution in Modern Japan
Prostitution in modern Japan, as defined under Japanese law, is the illegal practice of sexual intercourse with an 'unspecified' (unacquainted) person in exchange for monetary compensation, which was criminalised in 1956 by the introduction of article 3 of the Anti-Prostitution Law (ε£²ζ₯ι²ζ’ζ³, Baishun bΕshi hΕ). However, the definition of prostitution made illegal under this law is strictly limited to sexual intercourse with an 'unspecified person', and does not criminalise the sale of numerous other acts performed by sex workers in exchange for compensation, such as oral sex, anal sex, mammary intercourse, and other non-coital sex acts; the Businesses Affecting Public Morals Regulation Law of 1948 (ι’¨δΏεΆζ₯εη· ζ³, FΕ«zoku eigyΕ torishimari hΕ), also known as the "Law to Regulate Adult Entertainment Businesses", amended in 1985, 1999 and 2005, regulates these businesses, making only one definition of prostitution in Japan illegal.
Following the criminalisation of payment for sexual intercourse, the sex industry in Japan has developed into a number of varied businesses and offering services not prohibited under Japanese law. These fall into a number of categories known by various euphemistic names, such as soaplands, fashion health shops, and pink salons, with the term "health" commonly being a euphemism for sexual services. These businesses typically operate out of physical premises, either with their own employees or freelancers such as call girls, who may operate via Internet dating sites known as deai sites (Internet dating sites) or via delivery health services.

π Continuation-Passing Style
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.
