๐ Edward Snowden
Edward Joseph Snowden (born June 21, 1983) is an American whistleblower who copied and leaked highly classified information from the National Security Agency (NSA) in 2013 when he was a Central Intelligence Agency (CIA) employee and subcontractor. His disclosures revealed numerous global surveillance programs, many run by the NSA and the Five Eyes Intelligence Alliance with the cooperation of telecommunication companies and European governments, and prompted a cultural discussion about national security and individual privacy.
In 2013, Snowden was hired by an NSA contractor, Booz Allen Hamilton, after previous employment with Dell and the CIA. Snowden says he gradually became disillusioned with the programs with which he was involved and that he tried to raise his ethical concerns through internal channels but was ignored. On May 20, 2013, Snowden flew to Hong Kong after leaving his job at an NSA facility in Hawaii, and in early June he revealed thousands of classified NSA documents to journalists Glenn Greenwald, Laura Poitras, and Ewen MacAskill. Snowden came to international attention after stories based on the material appeared in The Guardian and The Washington Post. Further disclosures were made by other publications including Der Spiegel and The New York Times.
On June 21, 2013, the United States Department of Justice unsealed charges against Snowden of two counts of violating the Espionage Act of 1917 and theft of government property, following which the Department of State revoked his passport. Two days later, he flew into Moscow's Sheremetyevo Airport, where Russian authorities noted that his U.S. passport had been cancelled, and he was restricted to the airport terminal for over one month. Russia later granted Snowden the right of asylum with an initial visa for residence for one year, and repeated extensions have permitted him to stay at least until 2020. In early 2016, he became the president of the Freedom of the Press Foundation, a San Francisco-based organization that states its purpose is to protect journalists from hacking and government surveillance.
On September 17, 2019, his memoir Permanent Record was published. On the first day of publication, the U.S. Department of Justice filed a civil lawsuit against Snowden over publication of his memoir, alleging he had breached nondisclosure agreements signed with the U.S. federal government. Former The Guardian national security reporter Ewen MacAskill called the civil lawsuit a "huge mistake", noting that the "UK ban of Spycatcher 30 years ago created huge demand". The memoir was listed as no. 1 on Amazon's bestseller list that same day. In an interview with Amy Goodman on Democracy Now! on September 26, 2019, Snowden clarified he considers himself a "whistleblower" as opposed to a "leaker" as he considers "a leaker only distributes information for personal gain".

๐ Perpetual Bond
A perpetual bond, also known colloquially as a perpetual or perp, is a bond with no maturity date, therefore allowing it to be treated as equity, not as debt. Issuers pay coupons on perpetual bonds forever, and they do not have to redeem the principal. Perpetual bond cash flows are, therefore, those of a perpetuity.

๐ Lewis-Mogridge Position
The LewisโMogridge position, named after David Lewis and Martin J. H. Mogridge, was formulated in 1990 and observes that as more roads are built, more traffic consequently fills these roads. Speed gains from some new roads can disappear within months, if not weeks. Sometimes, new roads help to reduce traffic jams, but in most cases, the congestion is only shifted to another junction.
The position reads traffic expands to meet the available road space (Mogridge, 1990). It is generally referred to as induced demand in the transport literature, and was posited as the "Iron Law of Congestion" by Anthony Downs. It is a special case of Jevons paradox (where the resource in question is traffic capacity), and relates to the Marchetti's constant (average commute times are similar in widely varying conditions).
Following the position, it is not generally concluded that new roads are never justified but that their development needs to consider the whole traffic system, which means understanding the movement of goods and people in detail as well as the motivation behind the movement.
The position is often used to understand problems caused by private transport such as congested roads in cities and on motorways. It can also be used to explain the success of schemes such as the London congestion charge.
The position, however, is not confined to private transport. Mogridge, a British transport researcher, concluded also that all road investment in a congested urban area will have the effect of reducing the average speed of the transport system as a whole: road and public transport. The relationship and overall equilibria are also known as the "DownsโThomson paradox". However, according to Downs, the link between average speeds on public transport and private transport applies only "to regions in which the vast majority of peak-hour commuting is done on rapid transit systems with separate rights of way. Central London is an example, since in 2001 around 85 percent of all morning peak-period commuters into that area used public transit (including 77 percent on separate rights of way) and only 11 percent used private cars. When peak-hour travel equilibrium has been reached between the subway system and the major commuting roads, then the travel time required for any given trip is roughly equal on both modes."

๐ Incident Pit
An incident pit is a conceptual pit with sides that become steeper over time and with each new incident until a point of no return is reached. As time moves forward, seemingly innocuous incidents push a situation further toward a bad situation and escape from the incident pit becomes more difficult. An incident pit may or may not have a point of no return such as an event horizon.
It is a term used by divers, as well as engineers, medical personnel, and technology management personnel, to describe these situations and more importantly to avoid becoming ensnared.

๐ Eiffel programming language
Eiffel is an object-oriented programming language designed by Bertrand Meyer (an object-orientation proponent and author of Object-Oriented Software Construction) and Eiffel Software. Meyer conceived the language in 1985 with the goal of increasing the reliability of commercial software development; the first version becoming available in 1986. In 2005, Eiffel became an ISO-standardized language.
The design of the language is closely connected with the Eiffel programming method. Both are based on a set of principles, including design by contract, commandโquery separation, the uniform-access principle, the single-choice principle, the openโclosed principle, and optionโoperand separation.
Many concepts initially introduced by Eiffel later found their way into Java, C#, and other languages. New language design ideas, particularly through the Ecma/ISO standardization process, continue to be incorporated into the Eiffel language.

๐ James while John had had had ... had had had a better effect on the teacher
"James while John had had had had had had had had had had had a better effect on the teacher" is an English sentence used to demonstrate lexical ambiguity and the necessity of punctuation, which serves as a substitute for the intonation,stress, and pauses found in speech. In human information processing research, the sentence has been used to show how readers depend on punctuation to give sentences meaning, especially in the context of scanning across lines of text. The sentence is sometimes presented as a puzzle, where the solver must add the punctuation.
It refers to two students, James and John, required by an English test to describe a man who had suffered from a cold in the past. John writes "The man had a cold", which the teacher marks incorrect, while James writes the correct "The man had had a cold". Since James's answer was right, it had had a better effect on the teacher.
The sentence is much easier to understand with added punctuation and emphasis:
James, while John had had "had", had had "had had"; "had had" had had a better effect on the teacher.
In each of the five "had had" word pairs in the above sentence, the first of the pair is in the past perfect form. The italicized instances denote emphasis of intonation, focusing on the differences in the students' answers, then finally identifying the correct one.

๐ Uncleftish Beholding
"Uncleftish Beholding" (1989) is a short text by Poul Anderson designed to illustrate what English might look like without its large number of loanwords from languages such as French, Greek, and Latin. Written in a form of "Anglish," the work explains atomic theory using Germanic words almost exclusively and coining new words when necessary; many of these new words have cognates in modern German, an important scientific language in its own right. The title phrase uncleftish beholding calques "atomic theory."
To illustrate, the text begins:
For most of its being, mankind did not know what things are made of, but could only guess. With the growth of worldken, we began to learn, and today we have a beholding of stuff and work that watching bears out, both in the workstead and in daily life.
It goes on to define firststuffs (chemical elements), such as waterstuff (hydrogen), sourstuff (oxygen), and ymirstuff (uranium), as well as bulkbits (molecules), bindings (compounds), and several other terms important to uncleftish worldken (atomic science). Wasserstoff and Sauerstoff are the modern German words for hydrogen and oxygen, and in Dutch the modern equivalents are waterstof and zuurstof. Sunstuff refers to helium, which derives from แผฅฮปฮนฮฟฯ, the Ancient Greek word for "sun." Ymirstuff references Ymir, a giant in Norse mythology similar to Uranus in Greek mythology.
The vocabulary used in Uncleftish Beholding does not completely derive from Anglo-Saxon. Around, from Old French reond (Modern French rond), completely displaced Old English ymbe (cognate to German um) and left no "native" English word for this concept. The text also contains the French-derived words rest, ordinary and sort.
The text gained increased exposure and popularity after being circulated around the Internet, and has served as inspiration for some inventors of Germanic English conlangs. Douglas Hofstadter, in discussing the piece in his book Le Ton beau de Marot, jocularly refers to the use of only Germanic roots for scientific pieces as "Ander-Saxon."
