Beerware is a somewhat tongue-in-cheek term for software released under a very relaxed license (beerware licensed software). It provides the end user with the right to use a particular program (or do anything else with the source code).

🔗 Caves

Snottite, also snoticle, is a microbial mat of single-celled extremophilic bacteria which hang from the walls and ceilings of caves and are similar to small stalactites, but have the consistency of nasal mucus. In the Frasassi Caves in Italy, over 70% of cells in Snottite have been identified as Acidithiobacillus thiooxidans, with smaller populations including an archaeon in the uncultivated 'G-plasma' clade of Thermoplasmatales (>15%) and a bacterium in the Acidimicrobiaceae family (>5%).

The bacteria derive their energy from chemosynthesis of volcanic sulfur compounds including H₂S and warm-water solution dripping down from above, producing sulfuric acid. Because of this, their waste products are highly acidic (approaching pH=0), with similar properties to battery acid. Researchers at the University of Texas have suggested that this sulfuric acid may be a more significant cause of cave formation than the usual explanation offered of the carbonic acid formed from carbon dioxide dissolved in water.

Snottites were brought to attention by researchers Diana Northup and Penny Boston studying them (and other organisms) in a toxic sulfur cave called Cueva de Villa Luz (Cave of the Lighted House), in Tabasco, Mexico. Snottites were first discovered in this cave by Jim Pisarowicz in 1986, who also coined the term.

The BBC series Wonders of the Solar System saw Professor Brian Cox examining snottites and positing that if there is life on Mars, it may be similarly primitive and hidden beneath the surface of the Red Planet.

Potoooooooo or variations of Pot-8-Os (1773 – November 1800) was an 18th-century thoroughbred racehorse who won over 30 races and defeated some of the greatest racehorses of the time. He went on to be a sire. He is now best known for the unusual spelling of his name, pronounced 'Potatoes'.

🔗 China 🔗 Psychology

Guanxi (simplified Chinese: 关系; traditional Chinese: 關係; pinyin: guānxi) defines the fundamental dynamic in personalized social networks of power, and is a crucial system of beliefs in Chinese culture. In Western media, the pinyin romanization of this Chinese word is becoming more widely used instead of the two common translations of it—"connections" and "relationships"—as neither of those terms sufficiently reflects the wide cultural implications that guanxi describes.

Guanxi plays a fundamental role within the Confucian doctrine, which sees the individual as part of a community and a set of family, hierarchical and friendly relationships. In particular, there is a focus on tacit mutual commitments, reciprocity, and trust, which are the grounds of guanxi and guanxi networks.

Guanxi also has a major influence on the management of businesses based in Mainland China, and businesses owned by Overseas Chinese in Southeast Asia (the latter is known as the bamboo network).

Closely related concepts include that of ganqing, a measure which reflects the depth of feeling within an interpersonal relationship, renqing (人情 rénqíng/jen-ch'ing), the moral obligation to maintain a relationship, and the idea of "face" (面子, miànzi/mien-tzu), which refers to social status, propriety, prestige, or a combination of all three. Other related concepts include wu-lune, which supports the idea of a long term, developing relationship between a business and its client, and yi-ren and ren, which respectively support reciprocity and empathy.

🔗 United States 🔗 Skepticism 🔗 United States/Washington - Seattle 🔗 United States/Washington

The Seattle windshield pitting epidemic is a phenomenon which affected Bellingham, Seattle, and other communities of Washington state in April, 1954; it is considered an example of a mass delusion. It was characterized by widespread observation of previously unnoticed windshield holes, pits and dings, leading residents to believe that a common causative agent was at work. It was originally thought to be the work of vandals but the rate of pitting was so great that residents began to attribute it to everything from sand flea eggs to nuclear bomb testing.

Originating in Bellingham in March, police initially believed the work to be vandals using BB guns. However the pitting was soon observed in the nearby towns of Sedro Woolley and Mount Vernon and by mid-April, appeared to have spread to the town of Anacortes on Fidalgo Island.

Within a week, the news and the so-called "pitting epidemic" had reached metropolitan Seattle. As the newspapers began to feature the story, more and more reports of pitting were called in. Motorists began stopping police cars to report damage. Car lots and parking garages reported particularly severe attacks.

Several hypotheses for the widespread damage were postulated:

• Some thought that a new million-watt radio transmitter at nearby Jim Creek Naval Radio Station was producing waves that caused physical oscillations in glass;
• Some believed it to be the work of cosmic rays;
• Some reported seeing glass bubbles form right before their eyes, believing it to be the work of sand fleas.

By April 15, close to 3,000 windshields had been reported as affected. Mayor Allan Pomeroy contacted Washington Governor Arthur B. Langlie, then President Dwight D. Eisenhower asking for assistance.

Finally, Sergeant Max Allison of the Seattle police crime laboratory stated that the pitting reports consisted of "5 per cent hoodlum-ism, and 95 per cent public hysteria." By April 17, the pitting suddenly stopped.

The "Seattle Windshield Pitting Epidemic" as it is called has become a textbook case of collective delusion (not "mass hysteria" as reported). Although natural windshield pitting had been going on for some time, it was only when the media called public attention to it that people actually looked at their windshields and saw damage they had never noticed before.

A planimeter, also known as a platometer, is a measuring instrument used to determine the area of an arbitrary two-dimensional shape.

🔗 Politics

In popular discourse, the horseshoe theory asserts that the far-left and the far-right, rather than being at opposite and opposing ends of a linear continuum of the political spectrum, closely resemble each other, analogous to the way that the opposite ends of a horseshoe are close together. The theory is attributed to the French philosopher and writer of fiction and poetry Jean-Pierre Faye in his 2002 book Le Siècle des idéologies ("The Century of Ideologies").

Several political scientists, psychologists, and sociologists have criticized the horseshoe theory. Proponents point to a number of perceived similarities between extremes and allege that both have a tendency to support authoritarianism or totalitarianism; this does not appear to be supported by scholars in the field of political science, and the few instances of peer-reviewed research on the subject are scarce. Existing studies and comprehensive reviews often find only limited support and only under certain conditions; they generally contradict the theory's central premises.

The OODA loop is the cycle observe–orient–decide–act, developed by military strategist and United States Air Force Colonel John Boyd. Boyd applied the concept to the combat operations process, often at the operational level during military campaigns. It is now also often applied to understand commercial operations and learning processes. The approach explains how agility can overcome raw power in dealing with human opponents. It is especially applicable to cyber security and cyberwarfare.

The OODA loop has become an important concept in litigation, business, law enforcement, management education, and military strategy. According to Boyd, decision-making occurs in a recurring cycle of observe–orient–decide–act. An entity (whether an individual or an organization) that can process this cycle quickly, observing and reacting to unfolding events more rapidly than an opponent, can thereby "get inside" the opponent's decision cycle and gain the advantage.

SHRDLU was an early natural language understanding computer program, developed by Terry Winograd at MIT in 1968–1970. In it, the user carries on a conversation with the computer, moving objects, naming collections and querying the state of a simplified "blocks world", essentially a virtual box filled with different blocks.

SHRDLU was written in the Micro Planner and Lisp programming language on the DEC PDP-6 computer and a DEC graphics terminal. Later additions were made at the computer graphics labs at the University of Utah, adding a full 3D rendering of SHRDLU's "world".

The name SHRDLU was derived from ETAOIN SHRDLU, the arrangement of the letter keys on a Linotype machine, arranged in descending order of usage frequency in English.

🔗 Women 🔗 Women's History 🔗 Japan 🔗 Japan/History 🔗 Japan/Culture 🔗 Japan/Law and government 🔗 Feminism

Feminism in Japan began with women's rights movements that date back to antiquity. The movement started to gain momentum after Western thinking was brought into Japan during the Meiji Restoration in 1868. Japanese feminism differs from Western feminism in that less emphasis is placed on individual autonomy.

Prior to the late 19th century, Japanese women were bound by the traditional patriarchal system where senior male members of the family maintain their authority in the household. After the reforms brought by Meiji Restoration, women's status in Japanese society also went through series of changes. Trafficking of women was restricted, women were allowed to request divorces, and both boys and girls were required to receive elementary education. Further changes to women's status came about in the aftermath of World War II. Women received the right to vote, and a section of the new constitution drafted in 1946 was dedicated to guarantee gender equality.

In 1970, in the wake of the anti–Vietnam War movements, a new women's liberation movement called ūman ribu (woman lib) emerged in Japan from the New Left and radical student movements in the late 1960s. This movement was in sync with radical feminist movements in the United States and elsewhere, catalyzing a resurgence of feminist activism through the 1970s and beyond. The activists forwarded a comprehensive critique of the male-dominated nature of modern Japan, arguing for a fundamental change of the political-economic system and culture of the society. What distinguished them from previous feminist movements was their emphasis on sexual liberation (性の解放, sei no kaihō). They did not aim for equality with men, but rather focused on calling for men's liberation from the oppressive aspects of a patriarchal and capitalist system.

In 1979, the Convention on the Elimination of All Forms of Discrimination Against Women was adopted by the United Nations General Assembly. The Japanese government ratified it in 1985.
