Crimson Contagion was a simulation administered by the U.S. Department of Health and Human Services from January to August 2019 that tested the capacity of the U.S. federal government and twelve U.S. states to respond to a severe influenza pandemic originating in China. The exercise involves a scenario in which tourists returning from China spread a respiratory virus in the United States, beginning in Chicago. In less than two months the virus had infected 110 million Americans, killing more than half a million. The report issued at the conclusion of the exercise outlines the government's limited capacity to respond to a pandemic, with federal agencies lacking the funds, coordination, and resources to facilitate an effective response to the virus.

Gregory F. Packer (born December 18, 1963), is a retired American highway maintenance worker from Huntington, New York, best known for frequently being quoted as a "man on the street" in newspapers, magazines and television broadcasts from 1995 to the present. He has been quoted in hundreds of articles and television broadcasts as a member of the public (that is, a "man on the street" rather than a newsmaker or expert). Although he always gives his real name, he has admitted to making things up to get into the paper.

Packer's status as a frequent interviewee is due to a number of factors, including seeking out members of the press and appearing friendly, although mostly it is due to his hobby of attending public appearances of celebrities and other media events and attempting to be first in line on such occasions. This has led to him being dubbed a professional line sitter. It has also led to Packer's other claim to fame: being the first person in the world to buy an iPhone, on June 29, 2007 at Apple Fifth Avenue in New York City, after having camped out for five days in front of the store. (He tried to similarly be the first to buy an iPad in 2010, but was bumped from the first position in line due to not having a reservation.) His efforts to be first in line have also allowed him to meet people including Mariah Carey, Garth Brooks, Dennis Rodman and Ringo Starr, as well as at least four presidents of the United States: Jimmy Carter, Bill Clinton, George W. Bush and (before he became president) Donald Trump.

Tilt! How to get bias into a Wikipedia article

To all you budding propagandists in Wikiland: too many of you are working like a bunch of amateurs. Sorry to be so negative, but you have to understand that getting bias into the Wikipedia is a skill; it requires practice, finesse and imagination. It has to be learned; it is not a natural thing, though some have more talent for it than others.

I have been following the Middle East Wikipedia battleground for a few years now, and have been very impressed with the skill of some editors in introducing bias into articles. To ingenuous editors, some of these techniques may seem innocuous enough; in many cases, it is hard to see how proposed edits are biasing an article one way or another. It is, in fact, only in the last few months that I have been able to define what these techniques are and how they work to introduce bias.

The first thing you need to know as a budding propagandist is this: there are two levels at which bias is introduced into the Wikipedia: at the article level, and at the topic level. You need to set your sights high: you don't want to merely bias a single article, you want the entire Wikipedia on your side. Without understanding the importance of topic bias, it is hard to understand many of the article-level techniques, so I will start with the topic level.

International Talk Like a Pirate Day is a parodic holiday created in 1995 by John Baur (Ol' Chumbucket) and Mark Summers (Cap'n Slappy), of Albany, Oregon, U.S., who proclaimed September 19 each year as the day when everyone in the world should talk like a pirate. An observer of this holiday would greet friends not with "Hello, everyone!" but with "Ahoy, maties!" or "Ahoy, me hearties!" The holiday, and its observance, springs from a romanticized view of the Golden Age of Piracy.

The blinking twelve problem is a term used in software design. It usually refers to features in software or computer systems which are rendered unusable to most users by the complexity of the interface to them.

The usage emanates from the 'clock' feature provided on many VCRs manufactured in the late 1980s or early 1990s. The clock could be set by using a combination of buttons provided on the VCR in a specific sequence that was found complicated by most users. As a result, VCR users were known to seldom set the time on the VCR clock. This resulted in the default time of '12:00' blinking on the VCR display at all times of the day, which is the origin of this term.

"In most surveys, the majority of people have never time-shifted just because they don't know how to program their machines," said Tom Adams, a television analyst for Paul Kagan Associates, a media research firm, in 1990.

In software, 'the blinking twelve problem' thus refers to any situation in which features or functions of a program go unused for reasons that the designers never anticipated, largely because developers were unable to anticipate the level of understanding the users would have of the technology. The term may also refer to the challenge faced by developers of addressing the real causes of users' difficulties, as well as the challenge of providing helpful documentation or technical support without knowing beforehand how well the user understands their own problem.

In other instances, it can be used to reference the lack of basic user-friendly features in complex systems; stemming from the lack of a backup battery to keep the clock setting in a $300 VCR during even the briefest power interruption, when a $10 clock would have one.

The terms is usually used mostly by geeks, often in discussion forums. The term appears in the 1999 essay In the Beginning... Was the Command Line by Neal Stephenson.

Nihilistic violent extremism (NVE), or nihilistic extremism, is a term used by law enforcement agencies to refer to extremism and violence lacking an ideological motivation, instead motivated by a misanthropic worldview and generalized hatred for society. It is closely associated with groups such as 764 and No Lives Matter. Despite nihilistic violent extremism's characterization as being unmotivated by genuine ideology, groups or individuals falling under this umbrella may adopt the aesthetics or tactics of, or have sympathies for, other extremist ideologies like neo-Nazism, the variant of Satanism associated with the Order of Nine Angles, and accelerationism. It is also closely associated with sexual misconduct, such as solicitation, production, or possession of child pornography, and sextortion, as well as general violence.

In traditional Japanese aesthetics, wabi-sabi (侘寂) is a world view centered on the acceptance of transience and imperfection. The aesthetic is sometimes described as one of beauty that is "imperfect, impermanent, and incomplete". It is a concept derived from the Buddhist teaching of the three marks of existence (三法印, sanbōin), specifically impermanence (無常, mujō), suffering (苦, ku) and emptiness or absence of self-nature (空, kū).

Characteristics of the wabi-sabi aesthetic include asymmetry, roughness, simplicity, economy, austerity, modesty, intimacy, and appreciation of the ingenuous integrity of natural objects and processes.

C-- (pronounced C minus minus) is a C-like programming language. Its creators, functional programming researchers Simon Peyton Jones and Norman Ramsey, designed it to be generated mainly by compilers for very high-level languages rather than written by human programmers. Unlike many other intermediate languages, its representation is plain ASCII text, not bytecode or another binary format.

There are two main branches:

• C--, the original branch, with the final version 2.0 released in May 2005
• Cmm, the fork actively used as the intermediate representation (IR) in the Glasgow Haskell Compiler (GHC)

Teuvo Kalevi Kohonen (11 July 1934 – 15 December 2021) was a prominent Finnish academic (Dr. Eng.) and researcher. He was professor emeritus of the Academy of Finland.

Prof. Kohonen made many contributions to the field of artificial neural networks, including the Learning Vector Quantization algorithm, fundamental theories of distributed associative memory and optimal associative mappings, the learning subspace method and novel algorithms for symbol processing like redundant hash addressing. He has published several books and over 300 peer-reviewed papers.

Kohonen’s most famous contribution is the Self-Organizing Map (also known as the Kohonen map or Kohonen artificial neural networks, although Kohonen himself prefers SOM). Due to the popularity of the SOM algorithm in many research and in practical applications, Kohonen is often considered to be the most cited Finnish scientist. The current version of the SOM bibliography contains close to 8000 entries.

During most of his career, Prof. Kohonen conducted research at Helsinki University of Technology (TKK). The Neural Networks Research Centre of TKK, a center of excellence appointed by Academy of Finland was founded to conduct research related to Teuvo Kohonen's innovations. After Kohonen's retirement, the center was led by Prof. Erkki Oja and later renamed to Adaptive Informatics Research Centre with widened foci of research.

Teuvo Kohonen was elected the First Vice President of the International Association for Pattern Recognition from 1982 to 1984, and acted as the first president of the European Neural Network Society from 1991 to 1992.

For his scientific achievements, Prof. Kohonen has received a number of prizes including the following:

• IEEE Neural Networks Council Pioneer Award, 1991
• Technical Achievement Award of the IEEE Signal Processing Society, 1995
• IEEE Frank Rosenblatt Award, 2008

The bamboo-copter, also known as the bamboo dragonfly or Chinese top (Chinese zhuqingting (竹蜻蜓), Japanese taketonbo 竹蜻蛉), is a toy helicopter rotor that flies up when its shaft is rapidly spun. This helicopter-like top originated in Jin dynasty China around 320 AD, and was the object of early experiments by English engineer George Cayley, the inventor of modern aeronautics.

In China, the earliest known flying toys consisted of feathers at the end of a stick, which was rapidly spun between the hands and released into flight. "While the Chinese top was no more than a toy, it is perhaps the first tangible device of what we may understand as a helicopter."

The Jin dynasty Daoist philosopher Ge Hong's (c. 317) book Baopuzi (抱樸子 "Master Who Embraces Simplicity") mentioned a flying vehicle in what Joseph Needham calls "truly an astonishing passage".

Some have made flying cars [feiche 飛車] with wood from the inner part of the jujube tree, using ox-leather (straps) fastened to returning blades so as to set the machine in motion [huan jian yi yin chiji 環劍以引其機]. Others have had the idea of making five snakes, six dragons and three oxen, to meet the "hard wind" [gangfeng 罡風] and ride on it, not stopping until they have risen to a height of forty li. That region is called [Taiqing 太清] (the purest of empty space). There the [qi] is extremely hard, so much so that it can overcome (the strength of) human beings. As the Teacher says: "The kite (bird) flies higher and higher spirally, and then only needs to stretch its two wings, beating the air no more, in order to go forward by itself. This is because it starts gliding (lit. riding) on the 'hard wind' [gangqi 罡炁]. Take dragons, for example; when they first rise they go up using the clouds as steps, and after they have attained a height of forty li then they rush forward effortlessly (lit. automatically) (gliding)." This account comes from the adepts [xianren 仙人], and is handed down to ordinary people, but they are not likely to understand it.

Needham concludes that Ge Hong was describing helicopter tops because "'returning (or revolving) blades' can hardly mean anything else, especially in close association with a belt or strap"; and suggests that "snakes", "dragons", and "oxen" refer to shapes of man-lifting kites. Other scholars interpret this Baopuzi passage mythologically instead of literally, based on its context's mentioning fantastic flights through chengqiao (乘蹻 "riding on tiptoe/stilts") and xian (仙 "immortal; adept") techniques. For instance, "If you can ride the arches of your feet, you will be able to wander anywhere in the world without hindrance from mountains or rivers … Whoever takes the correct amulet and gives serious thought to the process may travel a thousand miles by concentrating his thoughts for one double hour." Compare this translation.

Some build a flying vehicle from the pith of the jujube tree and have it drawn by a sword with a thong of buffalo hide at the end of its grip. Others let their thoughts dwell on the preparation of a joint rectangle from five serpents, six dragons, and three buffaloes, and mount in this for forty miles to the region known as Paradise.

This Chinese helicopter toy was introduced into Europe and "made its earliest appearances in Renaissance European paintings and in the drawings of Leonardo da Vinci." The toy helicopter appears in a c. 1460 French picture of the Madonna and Child at the Musée du Palais de Tesse’ in Mans depicting the Child holding a toy copter sitting in Mary’s lap next to St Benôit (unknown artist), and in a 16th-century stained glass panel at the Victoria and Albert Museum in London. A picture from c. 1560 by Pieter Breughel the Elder at the Kunsthistorisches Museum in Vienna, Children's Games, depicts a helicopter top with three airscrews.

"The helicopter top in China led to nothing but amusement and pleasure, but fourteen hundred years later it was to be one of the key elements in the birth of modern aeronautics in the West." Early Western scientists developed flying machines based upon the original Chinese model. The Russian polymath Mikhail Lomonosov developed a spring-driven coaxial rotor in 1743, and the French naturalist Christian de Launoy created a bow drill device with contra-rotating feather propellers.

In 1792, George Cayley began experimenting with helicopter tops, which he later called "rotary wafts" or "elevating fliers". His landmark (1809) article "On Aerial Navigation" pictured and described a flying model with two propellers (constructed from corks and feathers) powered by a whalebone bow drill. "In 1835 Cayley remarked that while the original toy would rise no more than about 20 or 25 feet (6 or 7.5 metres), his improved models would 'mount upward of 90 ft (27 metres) into the air'. This then was the direct ancestor of the helicopter rotor and the aircraft propeller."

Discussing the history of Chinese inventiveness, the British scientist, sinologist, and historian Joseph Needham wrote, "Some inventions seem to have arisen merely from a whimsical curiosity, such as the 'hot air balloons' made from eggshells which did not lead to any aeronautical use or aerodynamic discoveries, or the zoetrope which did not lead onto the kinematograph, or the helicopter top which did not lead to the helicopter."
