A potato cannon is a pipe-based cannon that uses air pressure (pneumatic) or combustion of a flammable gas (aerosol, propane, etc.) to fire projectiles, usually potatoes. A simple design consists of a pipe sealed on one end, with a reducer on the other end to lower the diameter of the pipe, which has the corresponding lower-diameter pipe attached to it, called the barrel. Generally, the operator loads the projectile into the barrel, then utilizes a fuel or air pressure (or sometimes both) to propel the projectile out of the cannon.
The range of the cannon depends on many variables, including the type of fuel used, the efficiency of the fuel/air ratio, the combustion chamber/barrel ratio, and the flight characteristics of the projectile. Common distances vary from 100–200 meters (330–660 feet), and there is a reported case of a cannon exceeding 500 meters (1,600 feet) of range. The potato cannon can trace its origin to the World War II-era Holman Projector, which was a shipboard anti-aircraft weapon.

A party line (multiparty line, shared service line, party wire) is a local loop telephone circuit that is shared by multiple telephone service subscribers. Party line systems were widely used to provide telephone service, starting with the first commercial switchboards in 1878.
Party lines provided no privacy in communication. They were frequently used as a source of entertainment and gossip, as well as a means of quickly alerting entire neighborhoods of emergencies such as fires, becoming a cultural fixture of rural areas for many decades. Objections about one party monopolizing a multi-party line were a staple of complaints to telephone companies and letters to advice columnists for years and eavesdropping on calls remained an ongoing concern.

The Kia Challenge is a viral TikTok trend to which a series of motor vehicle thefts is attributed, targeting Kia and Hyundai vehicles in the U.S. manufactured between 2011 and 2021. The trend, which began in October 2022, has led to eight fatalities, according to the National Highway Traffic Safety Administration.
Until 2011, most Kia vehicles were manufactured with immobilizers—electronic security devices that prevent the engine from being started unless a proper key is inserted—a system present in most Hyundai vehicles until 2016. In Kia Sportage models manufactured in 2010, the immobilizer system comprised a transponder in the ignition key, an antenna coil in the key cylinder, and a SMARTRA unit. Kia vehicles manufactured from 2011 to 2021 and Hyundai vehicles manufactured from 2016 to 2021 that use a steel key, in comparison to a key fob and a push-button start mechanism, lack immobilizers.

The Hum is a name often given to widespread reports of a persistent and invasive low-frequency humming, rumbling, or droning noise audible to many but not all people. Hums have been reported all over the world. They are sometimes named according to the locality where the problem has been particularly publicized, such as the ‘Taos Hum’ in New Mexico and the ‘Windsor Hum’ in Ontario.
The Hum does not appear to be a single phenomenon. Different causes have been attributed, including local mechanical sources, often from industrial plants, as well as manifestations of tinnitus or other biological auditory effects.

The Sloot Digital Coding System is an alleged data sharing technique that its inventor claimed could store a complete digital movie file in 8 kilobytes of data — violating Shannon’s source coding theorem (which establishes the statistical limits to data compression) by many orders of magnitude. The alleged technique was developed in 1995 by Romke Jan Bernhard Sloot (1945-1999), a Dutch electronics engineer.
In 1999, just days before the conclusion of a contract to sell his invention, Sloot died suddenly of a heart attack. The source code was never recovered, and the technique and claim have never been reproduced or verified.

According to a false conspiracy theory, medbeds (an abbreviation of ‘medical bed’ or ‘meditation bed’) are secret beds that can miraculously heal humans and extend life. The plausibility of such devices is pseudoscience. Medbed conspiracy theories often involve claims that the devices are utilized by members of a ‘deep state’ and billionaires and that the former President of the United States, John F. Kennedy, is still alive, lying on a medbed.
Belief in these devices is popular among QAnon influencers such as Michael Protzman, Romana Didulo, and YamatoQ. Various companies sell devices or access to beds that supposedly heal ailments via imaginary technologies while also including fine print on their websites disclaiming that no diagnoses, treatment, or cures are provided.

EleutherAI is a grass-roots non-profit artificial intelligence (AI) research group. The group, considered an open-source version of OpenAI, was formed in a Discord server in July 2020 to organize a replication of GPT-3. In early 2023, it formally incorporated as the EleutherAI Foundation, a non-profit research institute. EleutherAI began as a Discord server on July 7, 2020 under the tentative name ‘LibreAI’ before rebranding to ‘EleutherAI’ later that month, in reference to eleutheria, an ancient greek term for liberty.
On December 30, 2020, EleutherAI released The Pile, a curated dataset of diverse text for training large language models.

Muda [moo-duh] is a Japanese word meaning ‘futility,’ ‘uselessness,’ or ‘wastefulness,’ and is a key concept in lean process thinking such as in the Toyota Production System (TPS), denoting one of three types of deviation from optimal allocation of resources. The other types are known by the Japanese terms ‘mura’ (‘unevenness’) and ‘muri’ (‘overload’). Waste in this context refers to the wasting of time or resources rather than wasteful by-products.
From an end-customer’s point of view, value-added work is any activity that produces goods or provides a service for which a customer is willing to pay; muda is any constraint or impediment that causes waste to occur.

Q* (pronounced ‘Q-star’) is an alleged internal project by OpenAI dedicated to the application of artificial intelligence in logical and mathematical reasoning. In November 2023, certain employees of OpenAI reportedly raised concerns with the company’s board, suggesting that Q* might signify the imminent emergence of artificial general intelligence. The reported work involves performing math on the level of grade-school students.
Math requires abstract reasoning and a firm grasp of logical principles. It’s not just about recognizing patterns or processing language, but about understanding and applying mathematical concepts and rules. Mathematics also demands precision and consistent application of rules, unlike many language tasks where approximations or multiple interpretations can be acceptable. An AI model that can reliably perform grade-school level math marks a significant advancement in the field, indicating progress towards more sophisticated and logically rigorous AI systems.

Roko’s basilisk [bas-uh-lisk] is a thought experiment which states that an otherwise benevolent artificial superintelligence (AI) in the future would be incentivized to create a virtual reality simulation to torture anyone who knew of its potential existence but did not directly contribute to its advancement or development, in order to incentivize said advancement.
It originated in a 2010 post at discussion board LessWrong, a technical forum focused on analytical rational enquiry. The thought experiment’s name derives from the poster of the article (Roko) and the basilisk, a mythical creature capable of destroying enemies with its stare.

A tachyonic [tak-ee-on-ik] antitelephone is a hypothetical device in theoretical physics that could be used to send signals into one’s own past. Albert Einstein in 1907 presented a thought experiment of how faster-than-light signals can lead to a paradox of causality, which was described by Einstein and Arnold Sommerfeld in 1910 as a means ‘to telegraph into the past.’ The same thought experiment was described by physicist Richard Chace Tolman in 1917; thus, it is also known as Tolman’s paradox.
A device capable of ‘telegraphing into the past’ was later also called a ‘tachyonic antitelephone’ by science fiction writer and astrophysicist Gregory Benford. According to current understanding of physics, no such faster-than-light transfer of information is actually possible.
