🔗 Military history 🔗 Military history/Intelligence 🔗 Journalism

Circular reporting, or false confirmation, is a situation in source criticism where a piece of information appears to come from multiple independent sources, but in reality comes from only one source. In many cases, the problem happens mistakenly through sloppy reporting or intelligence-gathering. However, the situation can also be intentionally contrived by the source or reporter as a way of reinforcing the widespread belief in its information.

This problem occurs in a variety of fields, including intelligence gathering, journalism, and scholarly research. It is of particular concern in military intelligence because the original source has a higher likelihood of wanting to pass on misinformation, and because the chain of reporting is more prone to being obscured. It is also a problem in journalism and the development of conspiracy theories, in which the primary goal of a source spreading unlikely or hard-to-believe information is to make it appear to be widely known.

The case of the 2002 Niger uranium forgeries was a classic instance of circular reporting by intelligence agencies.

Lee "Scratch" Perry (born Rainford Hugh Perry; 20/28 March 1936 – 29 August 2021) was a Jamaican record producer and singer noted for his innovative studio techniques and production style. Perry was a pioneer in the 1970s development of dub music with his early adoption of remixing and studio effects to create new instrumental or vocal versions of existing reggae tracks. He worked with and produced for a wide variety of artists, including Bob Marley and the Wailers, Junior Murvin, The Congos, Max Romeo, Adrian Sherwood, Beastie Boys, Ari Up, The Clash, The Orb, and many others.

🔗 Mathematics 🔗 Statistics

In statistical hypothesis testing, a type I error is the rejection of a true null hypothesis (also known as a "false positive" finding or conclusion), while a type II error is the non-rejection of a false null hypothesis (also known as a "false negative" finding or conclusion). Much of statistical theory revolves around the minimization of one or both of these errors, though the complete elimination of either is a statistical impossibility for non-deterministic algorithms. By selecting a low threshold (cut-off) value and modifying the alpha (p) level, the quality of the hypothesis test can be increased. The knowledge of Type I errors and Type II errors is widely used in medical science, biometrics and computer science.

🔗 Biography 🔗 Portugal

Álvaro de Campos (Portuguese pronunciation: [ˈalvɐɾu ðɨ ˈkɐ̃puʃ]; October 15, 1890 – November 30, 1935) was one of the poet Fernando Pessoa's various heteronyms, widely known by his powerful and wrathful writing style. According to his author, this alter ego was born in Tavira, Portugal, studied mechanical engineering and finally graduated in ship engineering in Glasgow. After a journey in Ireland, Campos sailed to the Orient and wrote his poem "Opiario" in the Suez Canal "onboard". He worked in 'Barrow-on-Furness' (sic) (of which Pessoa wrote a poem about) and Newcastle-on-Tyne (1922). Unemployed, Campos returned to Lisbon in 1926 (he wrote then the poem "Lisbon Revisited"), where he lived ever since. He was born in October, 1890, but Pessoa didn't put an end to the life of Campos, so he would have survived his author who died in November, 1935. Campos' works may be split in three phases: the decadent phase, the futuristic phase and the decadent (sad) phase. He chose Whitman and Marinetti as masters, showing some similarities with their works, mainly in the second phase: hymns like "Ode Triunfal", "Ode Marítima", and "Ultimatum" praise the power of the rising technology, the strength of the machines, the dark side of the industrial civilization, and an enigmatic love for the machines. The first phase (marked by the poem Opiário) shared some of its pessimism with Pessoa's friend Mário de Sá-Carneiro, one of his co-workers in Orpheu magazine. In the last phase, Pessoa drops the mask, and reveals through Campos all the emptiness and nostalgy that grew during his last years of life. In his last phase Campos wrote the poems "Lisbon Revisited" and the well-known "Tobaco Shop".

"I always want to be the thing I feel kinship with...
To feel everything in every way,
To hold all opinions,
To be sincere contradicting oneself every minute..."

🔗 Climate change 🔗 Oceans 🔗 Limnology and Oceanography

The ocean temperature varies by depth, geographical location and season. Both the temperature and salinity of ocean water differs. Warm surface water is generally saltier than the cooler deep or polar waters; in polar regions, the upper layers of ocean water are cold and fresh. Deep ocean water is cold, salty water found deep below the surface of Earth's oceans. This water has a very uniform temperature, around 0-3 °C. The ocean temperature also depends on the amount of solar radiation falling on its surface. In the tropics, with the Sun nearly overhead, the temperature of the surface layers can rise to over 30 °C (86 °F) while near the poles the temperature in equilibrium with the sea ice is about −2 °C (28 °F). There is a continuous circulation of water in the oceans. Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. Warm surface currents cool as they move away from the tropics, and the water becomes denser and sinks. The cold water moves back towards the equator as a deep sea current, driven by changes in the temperature and density of the water, before eventually welling up again towards the surface.

Ocean temperature as a term is used either for the temperature in the ocean at any depth, or specifically for the ocean temperatures that are not near the surface (in which case it is synonymous with "deep ocean temperature").

It is clear that the oceans are warming as a result of climate change and this rate of warming is increasing.^: 9 The upper ocean (above 700 m) is warming fastest, but the warming trend extends throughout the ocean. In 2022, the global ocean was the hottest ever recorded by humans.

Kowloon Walled City was an ungoverned, densely populated settlement in Kowloon City, Hong Kong. Originally a Chinese military fort, the Walled City became an enclave after the New Territories were leased to the UK by China in 1898. Its population increased dramatically following the Japanese occupation of Hong Kong during World War II. By 1990, the walled city contained 50,000 residents within its 2.6-hectare (6.4-acre) borders. From the 1950s to the 1970s, it was controlled by local triads and had high rates of prostitution, gambling, and drug abuse.

In January 1987, the Hong Kong municipal government announced plans to demolish the walled city. After an arduous eviction process, demolition began in March 1993 and was completed in April 1994. Kowloon Walled City Park opened in December 1995 and occupies the area of the former Walled City. Some historical artefacts from the walled city, including its yamen building and remnants of its southern gate, have been preserved there.

🔗 Germany 🔗 Food and drink 🔗 Brands

Volkswagen currywurst is a brand of sausage manufactured by the Volkswagen car maker since 1973. It is manufactured at the company's Wolfsburg plant and sold in restaurants in its six German factories. The currywurst are also sold externally at supermarkets and football stadiums and given away to Volkswagen customers. The sausage is branded as a "Volkswagen Original Part" and has been given the part number 199 398 500 A. The product has been described as the most produced of any of Volkswagen's parts, some 6.81 million sausages being manufactured in 2018. In many recent years the company has produced more sausages than cars. A Volkswagen ketchup is also produced and sold to accompany the currywurst.

🔗 Biography 🔗 Poetry 🔗 United Kingdom

The person from Porlock was an unwelcome visitor to Samuel Taylor Coleridge during his composition of the poem Kubla Khan in 1797. Coleridge claimed to have perceived the entire course of the poem in a dream (possibly an opium-induced haze), but was interrupted by this visitor from Porlock while in the process of writing it. Kubla Khan, only 54 lines long, was never completed. Thus "person from Porlock", "man from Porlock", or just "Porlock" are literary allusions to unwanted intruders who disrupt inspired creativity.

🔗 Computing

Amoeba is a distributed operating system developed by Andrew S. Tanenbaum and others at the Vrije Universiteit Amsterdam. The aim of the Amoeba project was to build a timesharing system that makes an entire network of computers appear to the user as a single machine. Development at the Vrije Universiteit was stopped: the source code of the latest version (5.3) was last modified on 30 July 1996.

The Python programming language was originally developed for this platform.

🔗 Computing

A lace card is a punched card with all holes punched (also called a whoopee card, ventilator card, flyswatter card, or IBM doily). They were mainly used as practical jokes to cause disruption in card readers. Card readers tended to jam when a lace card was inserted, as the resulting card had too little structural strength to avoid buckling inside the mechanism. Card punches could also jam trying to produce cards with all holes punched, owing to power-supply problems. When a lace card was fed through the reader, a card knife or card saw (a flat tool used with punched card readers and card punches) was needed to clear the jam.
