SpinLaunch is a spaceflight technology development company working on mass accelerator technology to move payloads to space.[3] As of September 2022, the company has raised US$150 million in funding, with investors including Kleiner Perkins, Google Ventures, Airbus Ventures, ATW Partners, Catapult Ventures, Lauder Partners, John Doerr, and the Byers Family.
SpinLaunch’s projected cost per kg of payload is approximately $1,250 – $2,500. This projection is significantly less expensive than SpaceX’s current price per kg of payload on the Falcon 9 of $6,000. SpaceX’s projected cost per kg on Starship, however, is less than $1,000 per kg. What real costs and prices for either SpinLaunch or Starship remains to be seen.

Slop is low-quality media—including writing and images—made using generative artificial intelligence technology. Coined in the 2020s, the term has a derogatory connotation akin to ‘spam.’ It has been variously defined as ‘digital clutter,’ ‘filler content produced by AI tools that prioritize speed and quantity over substance and quality,’ and ‘shoddy or unwanted AI content in social media, art, books and, increasingly, in search results.’ Jonathan Gilmore, a professor of philosophy at the City University of New York, describes the ‘incredibly banal, realistic style’ of AI slop as being ‘very easy to process.’
After Hurricane Helene, an AI-generated image of a girl holding a puppy while sitting in a boat floating on flooded waters circulated among Republicans, who used as evidence of failures or the Biden administration to respond to the disaster. U.S. Senator Mike Lee posted the image of the girl on social media before later deleting it. The image apparently originated on the Trump-centered Internet forum Patriots.win.

Tariff engineering refers to design and manufacturing decisions made primarily so that the manufactured good is classified at a lower rate for tariffs than it would have been absent those decisions. It is a loophole whereby an importer pays a lower tariff by changing the intended import such that the importer has a lesser tariff burden.
In contrast to tariff evasion, tariff engineering configures the design, material, or construction to legally achieve the desired classification rather than illegally misclassifying the product or good. For tariff engineering to be legal, the good being imported must be a ‘commercial reality,’ which means any tariff engineering must be a ‘genuine step in the manufacturing process’ or have a commercial use or identity as imported.

A reverse search warrant is a type of search warrant used in the U.S., in which law enforcement obtains a court order for information from technology companies to identify a group of people who may be suspects in a crime. They differ from traditional search warrants, which typically apply to specific individuals. Geofence warrants, which seek data on mobile phone users who were in a specific location at a given time, and keyword warrants, which request information on users who searched specific phrases, are two types of reverse search warrants.
Reverse location warrants were first used in 2016, and have become increasingly widely used by law enforcement. Google reported that it had received 982 reverse location warrants in 2018, 8,396 in 2019, and 11,554 in 2020. A 2021 transparency report showed that 25% of data requests from law enforcement to Google were geofence data requests. Google is the most common recipient of reverse location warrants and the main provider of such data, although companies including Apple, Snapchat, Lyft, and Uber have also received such warrants.

Speed wobble (also known as shimmy, tank-slapper, or speed wobble) is a rapid side-to-side shaking of a vehicle’s front wheel(s) that occurs at high speeds and can lead to loss of control. It presents as a quick (4–10 Hz) oscillation of primarily the steerable wheel(s) of a vehicle. It is caused by a combination of factors, including initial disturbances and insufficient damping, which can create a resonance effect. Initially, the rest of the vehicle remains mostly unaffected, until translated into a vehicle yaw oscillation of increasing amplitude producing loss of control.
Vehicles that can experience this oscillation include motorcycles and bicycles, skateboards, and, in theory, any vehicle with a single steering pivot point and a sufficient amount of freedom of the steered wheel, including that which exists on some light aircraft with tricycle gear where instability can occur at speeds of less than 80 km/h (50 mph); this does not include most automobiles. The initial instability occurs mostly at high speed and is similar to that experienced by shopping cart wheels and aircraft landing gear.

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.
