π State Capture
State capture is a type of systemic political corruption in which private interests significantly influence a state's decision-making processes to their own advantage.
The term was first used by the World Bank in 2000 to describe certain Central Asian countries making the transition from Soviet communism, where small corrupt groups used their influence over government officials to appropriate government decision-making in order to strengthen their own economic positions.
Allegations of state capture have led to protests against the government in Bulgaria in 2013β2014 and in 2020β2021 and Romania in 2017, and have caused an ongoing controversy in South Africa beginning in 2016. Turkey is considered as a post-2002 example of state capture. The term has also been used against Elon Musk by critics of U.S. President Donald Trump.

π Buffon's Needle Problem
In mathematics, Buffon's needle problem is a question first posed in the 18th century by Georges-Louis Leclerc, Comte de Buffon:
- Suppose we have a floor made of parallel strips of wood, each the same width, and we drop a needle onto the floor. What is the probability that the needle will lie across a line between two strips?
Buffon's needle was the earliest problem in geometric probability to be solved; it can be solved using integral geometry. The solution for the sought probability p, in the case where the needle length l is not greater than the width t of the strips, is
This can be used to design a Monte Carlo method for approximating the number Ο, although that was not the original motivation for de Buffon's question.

π Kei Car
Kei car (or keijidΕsha, kanji: θ»½θͺεθ», "light automobile", pronouncedΒ [keΛdΚidoΛΙa]), known variously outside Japan as Japanese city car, ultramini, or Japanese microcar, is the Japanese vehicle category for the smallest highway-legal passenger cars. Similar Japanese categories exist for microvans, and kei trucks. These vehicles are most often the Japanese equivalent of the EU A-segment (city cars).
The kei-car category was created by the Japanese government in 1949, and the regulations have been revised several times since. These regulations specify a maximum vehicle size, engine capacity, and power output, so that owners may enjoy both tax and insurance benefits. In most rural areas they are also exempted from the requirement to certify that adequate parking is available for the vehicle.
Kei cars have become very successful in Japan, consisting of over one-third of domestic new-car sales in fiscal 2016, despite dropping from a record 40% market share in 2013, after the government increased the kei-car tax by 50% in 2014. In 2018, seven of the 10 top-selling models were kei cars, including the top four, all boxy passenger vans: Honda N-Box, Suzuki Spacia, Nissan Dayz, and Daihatsu Tanto. Isuzu is the only manufacturer that has never offered a kei-sized vehicle for either private ownership or commercial trucks and microvans.
In export markets, though, the genre is generally too specialized and too small for most models to be profitable. Notable exceptions exist, though, for instance the Suzuki Alto and Jimny models, which were exported consistently from around 1980. Kei cars are not only popular with the elderly, but they are also popular with youths because of their affordability.
Nearly all kei cars have been designed and manufactured in Japan, but a version of the French-made Smart was briefly imported and officially classified as a kei car, and since then, the British Caterham 7 160 has also received such classification.

π Commons-based peer production
Commons-based peer production (CBPP) is a term coined by Harvard Law School professor Yochai Benkler. It describes a model of socio-economic production in which large numbers of people work cooperatively; usually over the Internet. Commons-based projects generally have less rigid hierarchical structures than those under more traditional business models. Oftenβbut not alwaysβcommons-based projects are designed without a need for financial compensation for contributors. For example, sharing of STL (file format) design files for objects freely on the internet enables anyone with a 3-D printer to digitally replicate the object saving the prosumer significant money.
The term is often used interchangeably with the term social production.

π Firefox Wikipedia Page Contains Recursive Screenshot of Itself
Mozilla Firefox or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Firefox uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface. Firefox is available for Windows 7 or Windows 10, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. Firefox is also available for Android and iOS. However, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements, as with all other iOS web browsers. An optimized version of Firefox is also available on the Amazon Fire TV, as one of the two main browsers available with Amazon's Silk Browser.
Firefox was created in 2002 under the code name "Phoenix" by the Mozilla community members who desired a standalone browser, rather than the Mozilla Application Suite bundle. During its beta phase, Firefox proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft's then-dominant Internet ExplorerΒ 6. Firefox was released on November 9, 2004, and challenged Internet Explorer's dominance with 60Β million downloads within nine months. Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998 before their acquisition by AOL.
Firefox usage share grew to a peak of 32.21% at the end of 2009, with Firefox 3.5 overtaking Internet Explorer 7, although not all versions of Internet Explorer as a whole. Usage then declined in competition with Google Chrome. As of AugustΒ 2021, according to StatCounter, Firefox has 7.62% usage share as a "desktop" web browser, making it the fourth-most popular web browser after Google Chrome (68.76%), Safari (9.7%) and Microsoft Edge (8.1%), while its usage share across all platforms is lower at 3.45% in third place (after Google Chrome with 65.27% and Safari with 18.34%).

π Sure-thing principle
In decision theory, the sure-thing principle states that a decision maker who would take a certain action if he knew that event E has occurred, and also if he knew that the negation of E has occurred, should also take that same action if he knows nothing about E.
The principle was coined by L.J. Savage:
A businessman contemplates buying a certain piece of property. He considers the outcome of the next presidential election relevant. So, to clarify the matter to himself, he asks whether he would buy if he knew that the Democratic candidate were going to win, and decides that he would. Similarly, he considers whether he would buy if he knew that the Republican candidate were going to win, and again finds that he would. Seeing that he would buy in either event, he decides that he should buy, even though he does not know which event obtains, or will obtain, as we would ordinarily say. It is all too seldom that a decision can be arrived at on the basis of this principle, but except possibly for the assumption of simple ordering, I know of no other extralogical principle governing decisions that finds such ready acceptance.
He formulated the principle as a dominance principle, but it can also be framed probabilistically. Richard Jeffrey and later Judea Pearl showed that Savage's principle is only valid when the probability of the event considered (e.g., the winner of the election) is unaffected by the action (buying the property). Under such conditions, the sure-thing principle is a theorem in the do-calculus (see Bayes networks). Blyth constructed a counterexample to the sure-thing principle using sequential sampling in the context of Simpson's paradox, but this example violates the required action-independence provision.
The principle is closely related to independence of irrelevant alternatives, and equivalent under the axiom of truth (everything the agent knows is true). It is similarly targeted by the Ellsberg and Allais paradoxes, in which actual people's choices seem to violate this principle.

π Emperor Norton
Joshua Abraham Norton (February 4, 1818Β β January 8, 1880), known as Emperor Norton, was a citizen of San Francisco, California, who proclaimed himself "Norton I, Emperor of the United States" in 1859. In 1863 he took the secondary title of "Protector of Mexico" after Napoleon III invaded that country. Norton was born in England but spent most of his early life in South Africa. He sailed west after the death of his mother in 1846 and his father in 1848, arriving in San Francisco possibly in November 1849.
Norton initially made a living as a businessman, but he lost his fortune investing in Peruvian rice to sell in China due to a Chinese rice shortage. He bought rice at 12 cents per pound from Peruvian ships, but more Peruvian ships arrived in port which caused the price to drop sharply to 4 cents. He then lost a lawsuit in which he tried to void his rice contract, and his public prominence faded. He re-emerged in September 1859, laying claim to the position of Emperor of the United States. Though Norton received many favors from the city, merchants also capitalized on his notoriety by selling souvenirs bearing his name. "San Francisco lived off the Emperor Norton," Norton's biographer William Drury wrote, "not Norton off San Francisco."
Norton had no formal political power; nevertheless, he was treated deferentially in San Francisco, and currency issued in his name was honored in the establishments that he frequented. Some considered him insane or eccentric, but citizens of San Francisco celebrated his imperial presence and his proclamations, such as his order that the United States Congress be dissolved by force and his numerous decrees calling for the construction of a bridge and tunnel crossing San Francisco Bay to connect San Francisco with Oakland.
On January 8, 1880, Norton collapsed at the corner of California and Dupont (now Grant) streets and died before he could be given medical treatment. Upwards of 30,000 people lined the streets of San Francisco to pay him homage at his funeral. Norton has been immortalized as the basis of characters in the literature of Mark Twain, Robert Louis Stevenson, Christopher Moore, Morris and RenΓ© Goscinny, Selma LagerlΓΆf, and Neil Gaiman.
