The Delphi method or Delphi technique ( DEL-fy; also known as Estimate-Talk-Estimate or ETE) is a structured communication technique or method, originally developed as a systematic, interactive forecasting method which relies on a panel of experts. The technique can also be adapted for use in face-to-face meetings, and is then called mini-Delphi or Estimate-Talk-Estimate (ETE). Delphi has been widely used for business forecasting and has certain advantages over another structured forecasting approach, prediction markets.

Delphi is based on the principle that forecasts (or decisions) from a structured group of individuals are more accurate than those from unstructured groups. The experts answer questionnaires in two or more rounds. After each round, a facilitator or change agent provides an anonymised summary of the experts' forecasts from the previous round as well as the reasons they provided for their judgments. Thus, experts are encouraged to revise their earlier answers in light of the replies of other members of their panel. It is believed that during this process the range of the answers will decrease and the group will converge towards the "correct" answer. Finally, the process is stopped after a predefined stop criterion (e.g., number of rounds, achievement of consensus, stability of results), and the mean or median scores of the final rounds determine the results.

Special attention has to be paid to the formulation of the Delphi theses and the definition and selection of the experts in order to avoid methodological weaknesses that severely threaten the validity and reliability of the results.

The Chrysler Turbine Car is an experimental two-door hardtop coupe powered by a turbine engine and manufactured by Chrysler from 1963–1964. The bodywork was constructed by Italian design studio Carrozzeria Ghia and Chrysler completed the final assembly in Detroit. A total of 55 cars were manufactured: five prototypes and a limited run of 50 cars for a public user program. All have a signature metallic paint named "turbine bronze", roughly the color of root beer. The car was styled by Elwood Engel and the Chrysler studios and featured power brakes, power steering, and a TorqueFlite transmission.

The Chrysler turbine engine program that produced the Turbine Car began during the late 1930s and created prototypes that completed long-distance trips in the 1950s and early 1960s. The A-831 engines that powered the Ghia-designed Turbine Car could operate on many fuels, required less maintenance, and lasted longer than conventional piston engines, although they were much more expensive to produce.

After testing, Chrysler conducted a user program from October 1963 to January 1966 that involved 203 drivers in 133 cities in the United States cumulatively driving more than one million miles (1.6 million km). The program helped the company determine problems with the cars, notably with their complicated starting procedure, relatively unimpressive acceleration, and sub-par fuel economy and noise. The experience also revealed advantages of the turbine engines, including their remarkable durability, smooth operation, and relatively modest maintenance requirements.

After the user program ended in 1966, Chrysler reclaimed the cars and destroyed all but nine; Chrysler kept two cars, six are displayed at museums in the United States, and one is in a private collection. Chrysler's turbine engine program ended in 1979, largely due to the failure of the engines to meet government emissions regulations, relatively poor fuel economy, and as a condition of receiving a government loan in 1979.

🔗 Computing

Technical debt (also known as design debt or code debt, but can be also related to other technical endeavors) is a concept in software development that reflects the implied cost of additional rework caused by choosing an easy (limited) solution now instead of using a better approach that would take longer.

As with monetary debt, if technical debt is not repaid, it can accumulate 'interest', making it harder to implement changes. Unaddressed technical debt increases software entropy. Technical debt is not necessarily a bad thing, and sometimes (e.g., as a proof-of-concept) is required to move projects forward. On the other hand, some experts claim that the "technical debt" metaphor tends to minimize the impact, which results in insufficient prioritization of the necessary work to correct it.

As a change is started on a codebase, there is often the need to make other coordinated changes in other parts of the codebase or documentation. Changes required that are not completed are considered debt, and until paid, will incur interest on top of interest, making it cumbersome to build a project. Although the term is used in software development primarily, it can also be applied to other professions.

The kóryos (Proto-Indo-European: "army, people under arms" or "detachment, war party") refers to the hypothetical Proto-Indo-European brotherhood of warriors in which unmarried young males served for a number of years before their full integration to the host society, in the context of a rite of passage into manhood.

Subsequent Indo-European traditions and myths feature parallel linkages between property-less adolescent males, perceived as an age-class not yet fully integrated into the community of the married men; their service in a "police-army" sent away for a part of the year in the wild (where they hunted animals and raided foreign communities) and defending the host society during the remaining part of the year; their mystical self-identification with wolves and dogs as symbols of death, promiscuity, lawlessness, and warrior fury; and the idea of a liminality between invulnerability and death on one side, and youth and adulthood on the other side.

Internet 0 is a low-speed physical layer designed to route 'IP over anything.' It was developed at MIT's Center for Bits and Atoms by Neil Gershenfeld, Raffi Krikorian, and Danny Cohen. When it was invented, a number of other proposals were being labelled as "internet 2." The name was chosen to emphasize that this was designed to be a slow, but very inexpensive internetworking system, and forestall "high-performance" comparison questions such as "how fast is it?"

Effectively, it would enable a platform for pervasive computing -- everything in a building could be on the same network to share data gathering and actuation. A light switch could turn on a light bulb by sending a packet to it, they can be linked together by the user.

Chanakya (IAST: Cāṇakya, pronunciation ) was an ancient Indian teacher, philosopher, economist, jurist and royal advisor. He is traditionally identified as Kauṭilya or Vishnugupta, who authored the ancient Indian political treatise, the Arthashastra, a text dated to roughly between the 3rd century BCE and the 3rd century CE. As such, he is considered the pioneer of the field of political science and economics in India, and his work is thought of as an important precursor to classical economics. His works were lost near the end of the Gupta Empire in the 6th century CE and not rediscovered until the early 20th century.

Chanakya assisted the first Mauryan emperor Chandragupta in his rise to power. He is widely credited for having played an important role in the establishment of the Maurya Empire. Chanakya served as the chief advisor to both emperors Chandragupta and his son Bindusara.

In criminal law, Blackstone's ratio (also known as the Blackstone ratio or Blackstone's formulation) is the idea that:

It is better that ten guilty persons escape than that one innocent suffer.

As expressed by the English jurist William Blackstone in his seminal work, Commentaries on the Laws of England, published in the 1760s.

The idea subsequently became a staple of legal thinking in Anglo-Saxon jurisdictions and continues to be a topic of debate. There is also a long pre-history of similar sentiments going back centuries in a variety of legal traditions. The message that government and the courts must err on the side of innocence has remained constant.

🔗 Internet culture 🔗 Skepticism

Time Cube was a personal web page, founded in 1997 by the self-proclaimed "wisest man on earth," Otis Eugene "Gene" Ray. It was a self-published outlet for Ray's theory of everything, called "Time Cube," which polemically claims that all modern sciences are participating in a worldwide conspiracy to teach lies, by omitting his theory's alleged truth that each day actually consists of four days occurring simultaneously. Alongside these statements, Ray described himself as a "godlike being with superior intelligence who has absolute evidence and proof" for his views. Ray asserted repeatedly and variously that "academia" had not taken Time Cube seriously.

Otis Eugene Ray died on March 18, 2015 at age 87. Ray's website domain names expired in August 2015, and Time Cube was last archived by the Wayback Machine on January 12, 2016. (January 10–14)
