🔗 Lloyd's Coffee House
Lloyd's Coffee House was a significant meeting place in London in the 17th and 18th centuries.
It was opened by Edward Lloyd (c. 1648–15 February 1713) on Tower Street in 1686. The establishment was a popular place for sailors, merchants and shipowners, and Lloyd catered to them by providing reliable shipping news. The shipping industry community frequented the place to discuss maritime insurance, shipbroking and foreign trade. The dealings that took place led to the establishment of the insurance market Lloyd's of London, Lloyd's Register and several related shipping and insurance businesses.
The coffee shop relocated to Lombard Street in December 1691. Lloyd had a pulpit installed in the new premises, from which maritime auction prices and shipping news were announced. Candle auctions were held in the establishment, with lots frequently involving ships and shipping. From 1696–1697 Lloyd also experimented with publishing a newspaper, Lloyd's News, reporting on shipping schedules and insurance agreements reached in the coffee house. In 1713, the year of Edward Lloyd's death, he modified his will to assign the lease of the coffee house to his head waiter, William Newton, who then married one of Lloyd's daughters, Handy. Newton died the following year and Handy subsequently married Samuel Sheppard. She died in 1720 and Sheppard died in 1727, leaving the coffee house to his sister Elizabeth and her husband, Thomas Jemson. Jemson founded the Lloyd's List newspaper in 1734, similar to the previous Lloyd's News. Merchants continued to discuss insurance matters here until 1774, when the participating members of the insurance arrangement formed a committee and moved to the Royal Exchange on Cornhill as the Society of Lloyd's.

🔗 Coffin Texts
The Coffin Texts are a collection of ancient Egyptian funerary spells written on coffins beginning in the First Intermediate Period. They are partially derived from the earlier Pyramid Texts, reserved for royal use only, but contain substantial new material related to everyday desires, indicating a new target audience of common people. Ordinary Egyptians who could afford a coffin had access to these funerary spells and the pharaoh no longer had exclusive rights to an afterlife.
As the modern name of this collection of some 1,185 spells implies, they were mostly inscribed on Middle Kingdom coffins. They were also sometimes written on tomb walls, stelae, canopic chests, papyri and mummy masks. Due to the limited writing surfaces of some of these objects, the spells were often abbreviated, giving rise to long and short versions, some of which were later copied in the Book of the Dead.

🔗 Strč Prst Skrz Krk
Strč prst skrz krk (pronounced [str̩tʃ pr̩st skr̩s kr̩k] (listen)) is a Czech and Slovak tongue-twister meaning "stick a finger through the throat".
The sentence is well known for being a semantically and syntactically valid clause without a single vowel, the nucleus of each syllable being a syllabic r, a common feature among many Slavic languages. It is often used as an example of such a phrase when learning Czech or Slovak as a foreign language.
In fact, both Czech and Slovak have two syllabic liquid consonants, the other being syllabic l. (There is also the syllabic bilabial nasal m in sedm in Czech.) As a result, there are plenty of words without vowels. Examples of long words of this type are scvrnkls, čtvrthrst, and čtvrtsmršť, the latter two being artificial occasionalisms.
There are other examples of vowelless sentences in Czech and Slovak, such as prd krt skrz drn, zprv zhlt hrst zrn, meaning "a mole farted through grass, having swallowed a handful of grains".
The longest Czech vowelless sentence (with 25 words and 82 consonants) as of 2013 is Škrt plch z mlh Brd pln skvrn z mrv prv hrd scvrnkl z brzd skrz trs chrp v krs vrb mls mrch srn čtvrthrst zrn. The meaning of the sentence is: Stingy dormouse from Brdy mountains fogs full of manure spots firstly proudly shrank a quarter of handful seeds, a delicacy for mean does, from brakes through bunch of Centaurea flowers into scrub of willows. IPA pronunciation of this sentence is [ʃkr̩t pl̩x zml̩x br̩t pl̩n skvr̩n zmr̩f pr̩f ɦr̩t st͡svrn̩kl̩ zbr̩st skr̩s tr̩s xr̩p fkr̩s vr̩p ml̩s mr̩x sr̩n t͡ʃtvrdɦr̩st zr̩n].

🔗 M-Pesa – a mobile-phone based money transfer and microfinancing service
M-Pesa (M for mobile, pesa is Swahili for money) is a mobile phone-based money transfer, financing and microfinancing service, launched in 2007 by Vodafone for Safaricom and Vodacom, the largest mobile network operators in Kenya and Tanzania. It has since expanded to Afghanistan, South Africa, India and in 2014 to Romania and in 2015 to Albania. M-Pesa allows users to deposit, withdraw, transfer money and pay for goods and services (Lipa na M-Pesa) easily with a mobile device.
The service allows users to deposit money into an account stored on their cell phones, to send balances using PIN-secured SMS text messages to other users, including sellers of goods and services, and to redeem deposits for regular money. Users are charged a small fee for sending and withdrawing money using the service.
M-Pesa is a branchless banking service; M-Pesa customers can deposit and withdraw money from a network of agents that includes airtime resellers and retail outlets acting as banking agents.
M-Pesa has spread quickly, and by 2010 had become the most successful mobile-phone-based financial service in the developing world. By 2012, a stock of about 17 million M-Pesa accounts had been registered in Kenya. By June 2016, a total of 7 million M-Pesa accounts have been opened in Tanzania by Vodacom. The service has been lauded for giving millions of people access to the formal financial system and for reducing crime in otherwise largely cash-based societies.

🔗 PACELC theorem for distributed databases – improves on CAP theorem
In theoretical computer science, the PACELC theorem is an extension to the CAP theorem. It states that in case of network partitioning (P) in a distributed computer system, one has to choose between availability (A) and consistency (C) (as per the CAP theorem), but else (E), even when the system is running normally in the absence of partitions, one has to choose between latency (L) and consistency (C).

🔗 FE-Schrift
The FE-Schrift or Fälschungserschwerende Schrift (forgery-impeding typeface) is a sans serif typeface introduced for use on licence plates. Its monospaced letters and numbers are slightly disproportionate to prevent easy modification and to improve machine readability. It has been developed in Germany where it has been mandatory since November 2000.
The abbreviation "FE" is derived from the compound German adjective "fälschungserschwerend" combining the noun "Fälschung" (falsification) and the verb "erschweren" (to hinder). "Schrift" means font in German. Other countries have later introduced the same or a derived typeface for license plates taking advantage of the proven design for the FE-Schrift.

🔗 Aral Sea
The Aral Sea ( ARR-əl; Kazakh: Арал теңізі, romanized: Aral teñızı; Uzbek: Орол денгизи, romanized: Orol dengizi; Karakalpak: Арал теңизи, romanized: Aral teńizi; Russian: Аральское море, romanized: Aral'skoye more) was an endorheic lake lying between Kazakhstan (Aktobe and Kyzylorda Regions) in the north and Uzbekistan (Karakalpakstan autonomous region) in the south which began shrinking in the 1960s and had largely dried up by the 2010s. The name roughly translates as "Sea of Islands", referring to over 1,100 islands that had dotted its waters. In the Mongolic and Turkic languages aral means "island, archipelago". The Aral Sea drainage basin encompasses Uzbekistan and parts of Tajikistan, Turkmenistan, Kyrgyzstan, Kazakhstan, Afghanistan, and Iran.
Formerly the fourth largest lake in the world with an area of 68,000 km2 (26,300 sq mi), the Aral Sea began shrinking in the 1960s after the rivers that fed it were diverted by Soviet irrigation projects. By 1997, it had declined to 10% of its original size, splitting into four lakes: the North Aral Sea, the eastern and western basins of the once far larger South Aral Sea, and the smaller intermediate Barsakelmes Lake.
By 2009, the southeastern lake had disappeared and the southwestern lake had retreated to a thin strip at the western edge of the former southern sea. In subsequent years occasional water flows have led to the southeastern lake sometimes being replenished to a small degree. Satellite images by NASA in August 2014 revealed that for the first time in modern history the eastern basin of the Aral Sea had completely dried up. The eastern basin is now called the Aralkum Desert.
In an ongoing effort in Kazakhstan to save and replenish the North Aral Sea, the Dike Kokaral dam was completed in 2005. By 2008, the water level had risen 12 m (39 ft) above that of 2003. Salinity has dropped, and fish are again present in sufficient numbers for some fishing to be viable. The maximum depth of the North Aral Sea was 42 m (138 ft) (as of 2008).
United Nations Secretary General Ban Ki-moon called the shrinking of the Aral Sea "one of the planet's worst environmental disasters". The region's once-prosperous fishing industry has been devastated, bringing unemployment and economic hardship. The water from the diverted Syr Darya river is used to irrigate about two million hectares (5,000,000 acres) of farmland in the Ferghana Valley. The Aral Sea region is heavily polluted, with consequent serious public health problems. UNESCO has added historical documents concerning the Aral Sea to its Memory of the World Register as a resource to study the environmental tragedy.

🔗 Ariel School UFO Incident
On September 16, 1994, there was a UFO sighting outside Ruwa, Zimbabwe. 62 students at the Ariel School aged between six and twelve claimed that they saw one or more silver craft descend from the sky and land on a field near their school. One or more creatures dressed all in black then approached the children and telepathically communicated to them a message with an environmental theme.
The Fortean writer Jerome Clark has called the incident the “most remarkable close encounter of the third kind of the 1990s”. Skeptics have described the incident as one of mass hysteria. Not all the children at the school that day claimed that they saw something. Several of those that did maintain that their account of the incident is true.
🔗 Tupolev Tu-144
The Tupolev Tu-144 (Russian: Tyполев Ту-144; NATO reporting name: Charger) is a retired jet airliner and commercial supersonic transport aircraft (SST). It was the world's first commercial SST (maiden flight – 31 December 1968), the second being the Anglo-French Concorde (maiden flight – 2 March 1969). The design was a product of the Tupolev design bureau, headed by Alexei Tupolev, of the Soviet Union and manufactured by the Voronezh Aircraft Production Association in Voronezh, Russia. It conducted 102 commercial flights, of which only 55 carried passengers, at an average service altitude of 16,000 metres (52,000 ft) and cruised at a speed of around 2,000 kilometres per hour (1,200 mph) (Mach 1.6).
The prototype's first flight was made on 31 December 1968, near Moscow from Zhukovsky Airport, two months before the first flight of Concorde. The Tu-144 first went supersonic on 5 June 1969 (Concorde first went supersonic on 1 October 1969), and on 26 May 1970 became the world's first commercial transport to exceed Mach 2. The aircraft used a new construction technique which resulted in large unexpected cracks, which resulted in several crashes. A Tu-144 crashed in 1973 at the Paris Air Show, delaying its further development. The aircraft was introduced into commercial service on 26 December 1975. In May 1978, another Tu-144 (an improved version, the Tu-144D) crashed on a test flight while being delivered. The aircraft remained in use as a cargo aircraft until 1983, when the Tu-144 commercial fleet was grounded. The Tu-144 was later used by the Soviet space program to train pilots of the Buran spacecraft, and by NASA for supersonic research until 1999, when the Tu-144 made its last flight (26 June 1999).

🔗 Hyperion (Tree)
Hyperion is a coast redwood (Sequoia sempervirens) in California that is the world's tallest known living tree, measured at 116.07 metres (380.8 ft) tall in 2019.
Hyperion was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor. The tree height of 115.55 m (379.1 ft) was verified by Stephen Sillett in 2006 using both a laser range finder and a fiberglass tape to measure the tree from the base to the crown. The tree has grown since then to reach 116.07 metres (380.8 ft) recorded in 2019. Hyperion was found in a remote area of Redwood National Park, inside of the originally designated park boundaries of 1968. The park also houses the second-, fourth- and fifth-tallest known trees, coast redwoods named Helios, Icarus, and Daedalus, which respectively measured 377, 371 and 363 feet in 2022.
The tree was named after the titan Hyperion from Greek mythology.
Hyperion is estimated to be between 600 and 800 years old and contain 530 m3 (18,600 cu ft) of wood.
The exact location of Hyperion is nominally secret but is available via internet search. However, in July 2022, the Redwood Park superintendent closed the entire area around the tree, citing "devastation of the habitat surrounding Hyperion" caused by visitors. Its base was trampled by the overuse and as a result ferns no longer grow around the tree. Anyone who gets too close could face up to six months in jail and a $5,000 maximum fine.
