"The Californian Ideology" is a 1995 essay by English media theorists Richard Barbrook and Andy Cameron of the University of Westminster. Barbrook describes it as a "critique of dotcom neoliberalism". In the essay, Barbrook and Cameron argue that the rise of networking technologies in Silicon Valley in the 1990s was linked to American neoliberalism and a paradoxical hybridization of beliefs from the political left and right in the form of hopeful technological determinism.

The original essay was published in Mute magazine in 1995 and later appeared on the nettime Internet mailing list for debate. A final version was published in Science as Culture in 1996. The critique has since been revised in several different versions and languages.

Andrew Leonard of Salon called Barbrook & Cameron's work "one of the most penetrating critiques of neo-conservative digital hypesterism yet published."

🔗 Sports

Extreme ironing (also called EI) is an extreme sport in which people take ironing boards to remote locations and iron items of clothing. According to the Extreme Ironing Bureau, extreme ironing is "the latest danger sport that combines the thrills of an extreme outdoor activity with the satisfaction of a well-pressed shirt."

Part of the attraction and interest the media has shown towards extreme ironing seems to center on the issue of whether it is really a sport or not. It is widely considered to be tongue-in-cheek.

Some other locations where such performances have taken place include a mountainside of a difficult climb; a forest; in a canoe; while skiing or snowboarding; on top of large bronze statues; in the middle of a street; underwater; in the middle of the M1 motorway; race; whilst parachuting; and under the ice sheet of a frozen lake. The performances have been conducted solo or by groups.

Biophilic design is a concept used within the building industry to increase occupant connectivity to the natural environment through the use of direct nature, indirect nature, and space and place conditions. Used at both the building and city-scale, it is argued that this idea has health, environmental, and economic benefits for building occupants and urban environments, with few drawbacks. Although its name was coined in recent history, indicators of biophilic design have been seen in architecture from as far back as the Hanging Gardens of Babylon.

JScript is Microsoft's dialect of the ECMAScript standard that is used in Microsoft's Internet Explorer.

JScript is implemented as an Active Scripting engine. This means that it can be "plugged in" to OLE Automation applications that support Active Scripting, such as Internet Explorer, Active Server Pages, and Windows Script Host. It also means such applications can use multiple Active Scripting languages, e.g., JScript, VBScript or PerlScript.

JScript was first supported in the Internet Explorer 3.0 browser released in August 1996. Its most recent version is JScript 9.0, included in Internet Explorer 9.

JScript 10.0 is a separate dialect, also known as JScript .NET, which adds several new features from the abandoned fourth edition of the ECMAScript standard. It must be compiled for .NET Framework version 2 or version 4, but static type annotations are optional.

Mean world syndrome is a cognitive bias where people perceive the world to be more dangerous than it actually is due to long-term, moderate to heavy exposure to violence-related content on mass media.

Mean world syndrome asserts that viewers who are exposed to violence-related content can experience increased fear, anxiety, pessimism and heightened state of alert in response to perceived threats. This is because media (namely television) consumed by viewers has the power to directly influence and inform their attitudes, beliefs and opinions about the world.

Dr. George Gerbner, who coined the term mean world syndrome in the 1970s, began his research on the effects of violent media on individuals’ attitudes by claiming that a major cultural shift was taking place, where "who tells the stories of a culture really governs human behavior. It used to be the parent, the school, the church, the community. Now it's a handful of global conglomerates that have nothing to tell, but a great deal to sell."

Since TV was becoming an ever increasing presence in the average American household and the amount of violence on TV was growing exponentially, Gerbner conducted several large-scale studies that upheld his hypothesis: those who watched moderate to large amounts of TV believed the world to be a more dangerous place.

Since the 1970s, numerous studies have corroborated Gerbner's findings that moderate to heavy viewing of violence-related content on TV increased depression, fear, anxiety, anger, pessimism, post-traumatic stress and substance use. For example, in 2009, the American Academy of Pediatrics released a policy statement on media violence which concluded that “extensive research evidence indicates that media violence can contribute to aggressive behavior, desensitization to violence, nightmares, and fear of being harmed.”

🔗 Psychology

Inductive reasoning aptitude (also called differentiation or inductive learning ability) measures how well a person can identify a pattern within a large amount of data. It involves applying the rules of logic when inferring general principles from a constellation of particulars.

Measurement is generally done in a timed test by showing four pictures or words and asking the test taker to identify which of the pictures or words does not belong in the set. The test taker is shown a large number of sets of various degrees of difficulty. The measurement is made by timing how many of these a person can properly identify in a set period of time. The test resembles the game 'Which of These Is Not Like the Others'.

Inductive reasoning is very useful for scientists, auto mechanics, system integrators, lawyers, network engineers, medical doctors, system administrators and members of all fields where substantial diagnostic or data interpretation work is needed. Inductive reasoning aptitude is also useful for learning a graphical user interface quickly, because highly inductive people are very good at seeing others' categorization schemes. Inductive reasoning aptitude is often counter-productive in fields like sales where tolerance is very important, because highly inductive people tend to be good at seeing faults in others.

A hydraulic empire, also known as a hydraulic despotism, hydraulic society, hydraulic civilization, or water monopoly empire, is a social or government structure which maintains power and control through exclusive control over access to water. It arises through the need for flood control and irrigation, which requires central coordination and a specialized bureaucracy.

Often associated with these terms and concepts is the notion of a water dynasty. This body is a political structure which is commonly characterized by a system of hierarchy and control often based on class or caste. Power, both over resources (food, water, energy) and a means of enforcement such as the military, is vital for the maintenance of control.
