"i am lonely will anyone speak to me" is the title of a thread that was posted on the Internet forum of the video codec downloads site Moviecodec.com, and had become "the web's top hangout for lonely folk". The thread began July 14, 2004; it was the first hit when the phrase "I am lonely" was entered into the Google search engine though it has since dropped.

It was featured in the magazines Wired, Guardian Unlimited, and The New Yorker. Bjarne Lundgren, the webmaster of Moviecodec.com, has stated "Like-minded people tend to flock together and, in this case, Google helped in flocking them together on my site".

Mark Griffiths, a researcher in internet psychology at Nottingham Trent University in the UK, also addressed this question, stating: "There are a lot of lonely people out there. Some people rely heavily on technology and end up treating it as an electronic friend, a sounding board—just writing it down can make you feel better... That doesn't change their psychological world at that moment, but creating a kinship with like-minded people can help. You're all in this virtual space together."

Due to its large community, Bjarne created a new forum entitled "A Lonely Life", for the thread's numerous lonely inhabitants to move to. The original thread is now located on Moviecodec.com's branch site, The Lounge Forums.

As of December 24, 2016, the website the thread is hosted on was shut down and can no longer be accessed.

The 2020 United States Postal Service crisis is a series of events that have caused backlogs and delays in the delivery of mail by the United States Postal Service (USPS). The crisis stems primarily from changes implemented by Postmaster General Louis DeJoy shortly after taking office in June 2020. The delays have had substantial legal, political, economic, and health repercussions.

There is controversy and speculation about whether the delays are unintended consequences of restructuring operations, or if they were intentionally created for political and/or financial gain. DeJoy has supported and donated to President Donald Trump, who has publicly linked his opposition to emergency funding for the Postal Service to his desire to restrict voting by mail in the 2020 elections.

On August 18, 2020, under heavy political and legal pressure, DeJoy announced that he would be "suspending" the policy changes until after the November 2020 election. He testified to the Senate on August 21, and to the House of Representatives on August 24, concerning the changes and their effects.

🔗 Computer science 🔗 Mathematics 🔗 Systems

An L-system or Lindenmayer system is a parallel rewriting system and a type of formal grammar. An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial "axiom" string from which to begin construction, and a mechanism for translating the generated strings into geometric structures. L-systems were introduced and developed in 1968 by Aristid Lindenmayer, a Hungarian theoretical biologist and botanist at the University of Utrecht. Lindenmayer used L-systems to describe the behaviour of plant cells and to model the growth processes of plant development. L-systems have also been used to model the morphology of a variety of organisms and can be used to generate self-similar fractals.

International Day to End Violence Against Sex Workers is observed annually on December 17 by sex workers, their advocates, friends, families and allies. Originally conceived as a memorial and vigil for the victims of the Green River Killer in Seattle Washington, United States (US), it has evolved into an annual international event. The day calls attention to hate crimes committed against sex workers worldwide, as well as the need to remove the social stigma and discrimination that have contributed to violence against sex workers and indifference from the communities they are part of. Sex worker activists also state that custom and prohibitionist laws perpetuate such violence.

🔗 Biography 🔗 Biography/science and academia 🔗 Egypt

Taqi al-Din Muhammad ibn Ma'ruf ash-Shami al-Asadi (Arabic: تقي الدين محمد بن معروف الشامي‎, Ottoman Turkish: تقي الدين محمد بن معروف الشامي السعدي‎, Turkish: Takiyüddin) (1526-1585) was an Ottoman polymath active in Cairo and Istanbul. He was the author of more than ninety books on a wide variety of subjects, including astronomy, clocks, engineering, mathematics, mechanics, optics and natural philosophy.

In 1574 the Ottoman Sultan Murad III invited Taqī ad-Dīn to build the Constantinople observatory. Using his exceptional knowledge in the mechanical arts, Taqī ad-Dīn constructed instruments like huge armillary and mechanical clocks that he used in his observations of the Great Comet of 1577. He also used European celestial and terrestrial globes that were delivered to Istanbul in gift-exchange.

The major work that resulted from his work in the observatory is titled "The tree of ultimate knowledge [in the end of time or the world] in the Kingdom of the Revolving Spheres: The astronomical tables of the King of Kings [Murād III]" (Sidrat al-muntah al-afkar fi malkūt al-falak al-dawār– al-zij al-Shāhinshāhi). The work was prepared according to the results of the observations carried out in Egypt and Istanbul in order to correct and complete Ulugh Beg's Zij as-Sultani. The first 40 pages of the work deal with calculations, followed by discussions of astronomical clocks, heavenly circles, and information about three eclipses which he observed at Cairo and Istanbul. For corroborating data of other observations of eclipses in other locales like Daud ar-Riyyadi (David the Mathematician), David Ben-Shushan of Salonika.

As a polymath, Taqī al-Dīn wrote numerous books on astronomy, mathematics, mechanics, and theology. His method of finding coordinates of stars were reportedly so precise that he got better measurements than his contemporaries, Tycho Brahe and Nicolas Copernicus. Brahe is also thought to have been aware of al-Dīn's work.

Taqī Ad-Dīn also described a steam turbine with the practical application of rotating a spit in 1551. He worked on and created astronomical clocks for his observatory. Taqī Ad-Dīn also wrote a book on optics, in which he determined the light emitted from objects, proved the Law of Reflection observationally, and worked on refraction.

Occasionally, some long-time users come to believe they are more important than other editors, and act in ways to seek regular validation of that belief. Validation is obtained by delivering and obtaining compliance with ultimatums, such as threatening to storm off the project in a huff – a "retirement" or long wikibreak. Other examples including threats to make vexatious claims at noticeboards, or to cease all work in a particular topic area. These dramatics are usually accompanied by a long diatribe about whatever petty issue is driving them away this time.

The writer hopes that this fit of pique will attract a flood of "please don't go" messages, along with plenty of support for their side of the dispute that triggered their round of unreasonable demands. The end result sought is that the "high-maintenance" editing behavior gets the editor exactly what they crave – validation and support – leading to a triumphant return to the project or article, at least until the next petty conflict. Because Wikipedia is not therapy (even if it was, this behavior would be undesirable) or, more importantly, not a soapbox, and most other editors can see through this sort of behavior, such an outcome is unlikely, and becomes decreasingly likely the more times such a door-slamming conniption is attempted, until people hope the editor really quits.

Threats to "leave and never come back" inevitably invite the response: don't let the door hit you on the way out.

🔗 Physics 🔗 Astronomy

In astrophysics and physical cosmology, Olbers' paradox, named after the German astronomer Heinrich Wilhelm Olbers (1758–1840), also known as the "dark night sky paradox", is the argument that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe. In the hypothetical case that the universe is static, homogeneous at a large scale, and populated by an infinite number of stars, any line of sight from Earth must end at the surface of a star and hence the night sky should be completely illuminated and very bright. This contradicts the observed darkness and non-uniformity of the night.

The darkness of the night sky is one of the pieces of evidence for a dynamic universe, such as the Big Bang model. That model explains the observed non-uniformity of brightness by invoking spacetime's expansion, which lengthens the light originating from the Big Bang to microwave levels via a process known as redshift; this microwave radiation background has wavelengths much longer than those of visible light, and so appears dark to the naked eye. Other explanations for the paradox have been offered, but none have wide acceptance in cosmology.

🔗 Linguistics 🔗 Linguistics/Etymology

OK (spelling variations include okay, O.K., and ok) is an English word (originally American English) denoting approval, acceptance, agreement, assent, acknowledgment, or a sign of indifference. OK is frequently used as a loanword in other languages. It has been described as the most frequently spoken or written word on the planet. The origins of the word are disputed.

As an adjective, OK principally means "adequate" or "acceptable" as a contrast to "bad" ("The boss approved this, so it is OK to send out"); it can also mean "mediocre" when used in contrast with "good" ("The french fries were great, but the burger was just OK"). It fulfills a similar role as an adverb ("Wow, you did OK for your first time skiing!"). As an interjection, it can denote compliance ("OK, I will do that"), or agreement ("OK, that is fine"). It can mean "assent" when it is used as a noun ("the boss gave her the OK to the purchase") or, more colloquially, as a verb ("the boss OKed the purchase"). OK, as an adjective, can express acknowledgement without approval. As a versatile discourse marker or back-channeling item, it can also be used with appropriate intonation to show doubt or to seek confirmation ("OK?", "Is that OK?").

🔗 Sociology

The circulation of elite is a theory of regime change described by Italian social scientist Vilfredo Pareto (1848–1923).

Changes of regime, revolutions, and so on occur not when rulers are overthrown from below, but when one elite replaces another. The role of ordinary people in such transformation is not that of initiators or principal actors, but as followers and supporters of one elite or another.

🔗 Paranormal 🔗 Scientology

Xenu (), also called Xemu, was, according to Scientology founder L. Ron Hubbard, the dictator of the "Galactic Confederacy" who brought billions of his people to Earth (then known as "Teegeeack") in DC-8-like spacecraft 75 million years ago, stacked them around volcanoes, and killed them with hydrogen bombs. Official Scientology scriptures hold that the thetans (immortal spirits) of these aliens adhere to humans, causing spiritual harm.

These events are known within Scientology as "Incident II", and the traumatic memories associated with them as "The Wall of Fire" or "R6 implant". The narrative of Xenu is part of Scientologist teachings about extraterrestrial civilizations and alien interventions in earthly events, collectively described as "space opera" by Hubbard. Hubbard detailed the story in Operating Thetan level III (OT III) in 1967, warning that the "R6 implant" (past trauma) was "calculated to kill (by pneumonia, etc.) anyone who attempts to solve it".

Within the Church of Scientology, the Xenu story is part of the church's secret "Advanced Technology", considered a sacred and esoteric teaching, which is normally only revealed to members who have completed a lengthy sequence of courses costing large amounts of money. The church avoids mention of Xenu in public statements and has gone to considerable effort to maintain the story's confidentiality, including legal action on the grounds of copyright and trade secrecy. Officials of the Church of Scientology widely deny or try to hide the Xenu story. Despite this, much material on Xenu has leaked to the public via court documents and copies of Hubbard's notes that have been distributed through the Internet. In commentary on the impact of the Xenu text, academic scholars have discussed and analyzed the writings by Hubbard and their place within Scientology within the contexts of science fiction, UFO religions, Gnosticism and creation myths.
