πŸ”— Apple Inc. πŸ”— Video games πŸ”— Chess

Battle Chess is a computer game version of chess in which the chess pieces come to life and battle one another when capturing. It was originally developed and released by Interplay Entertainment for the Amiga in 1988 and subsequently on many other systems, including 3DO Interactive Multiplayer, Acorn Archimedes, Amiga CD32, Amiga CDTV, Apple IIGS, Apple IIe, Atari ST, Commodore 64, MS-DOS, FM Towns, NES, Mac OS, NEC PC-9801, X68000 and Microsoft Windows. In 1991, Battle Chess Enhanced was released by Interplay for the PC, featuring improved VGA graphics and a symphonic musical score that played from the CD-ROM.

Battle Chess was critically acclaimed and commercially successful, resulting in two official follow-ups as well as several inspired games. Its remake, Battle Chess: Game of Kings, was released on Steam on December 11, 2015.

πŸ”— Dril

πŸ”— Biography πŸ”— Internet culture πŸ”— Comedy πŸ”— Biography/arts and entertainment

@dril is a pseudonymous Twitter user best known for his idiosyncratic style of absurdist humor and non sequiturs. The account, its author, and the character associated with the tweets are all commonly referred to as dril (the handle without the at sign) or wint (the account's display name), both rendered lowercase but often capitalized by others. Since his first tweet in 2008, dril has become a popular and influential Twitter user with more than one million followers.

dril is one of the most notable accounts associated with "Weird Twitter", a subculture on the site that shares a surreal, ironic sense of humor. The character associated with dril is highly distinctive, often described as a bizarre reflection of a typical male American Internet user. Other social media users have repurposed dril's tweets for humorous or satiric effect in a variety of political and cultural contexts. Many of dril's tweets, phrases, and tropes have become familiar parts of Internet slang.

The author behind dril remained unknown for years, with the few available details about the author's life fueling speculation about his identity. In 2017, dril's author was "doxxed" (in other words, his identity was exposed) in a post that went viral and received media attention. After the doxxing, many Twitter users and journalists preferred to preserve dril's pseudonymity out of respect for the author's personal privacy and the character's mystique.

Beyond tweeting, dril has created animated short films and contributed illustrations and writing to other artists' collaborative projects. His first book, Dril Official "Mr. Ten Years" Anniversary Collection (2018), is a compilation of the account's "greatest hits" alongside new illustrations. In 2019 he announced the launch of a streaming web series called Truthpoint: Darkweb Rising, an InfoWars parody co-created with comedian Derek Estevez-Olsen for Adult Swim. Writers have praised dril for the originality and humor of his tweets; for example, the poet Patricia Lockwood called dril "a master of tone [and] character," and The A.V. Club dubbed him "arguably the most iconic Twitter account in the history of social media."

πŸ”— Kobayashi Maru

πŸ”— Star Trek

The Kobayashi Maru is a training exercise in the fictional Star Trek universe designed to test the character of Starfleet Academy cadets in a no-win scenario. The Kobayashi Maru test was first depicted in the opening scene of the film Star Trek II: The Wrath of Khan and also appears in the 2009 film Star Trek. Screenwriter Jack B. Sowards is credited with inventing the test. The test's name is occasionally used among Star Trek fans or those familiar with the series to describe a no-win scenario, a test of one's character or a solution that involves redefining the problem and managing an insurmountable scenario gracefully.

The notional primary goal of the exercise is to rescue the civilian vessel Kobayashi Maru in a simulated battle with the Klingons. The disabled ship is located in the Klingon Neutral Zone, and any Starfleet ship entering the zone would cause an interstellar border incident. The approaching cadet crew must decide whether to attempt rescue of the Kobayashi Maru crewβ€”endangering their own ship and livesβ€”or leave the Kobayashi Maru to certain destruction. If the cadet chooses to attempt rescue, the simulation is designed to guarantee that the cadet's ship enters a situation that he or she will have absolutely no chance of winning, escaping, negotiating or even surviving.

πŸ”— X17 Particle

πŸ”— Physics

The X17 particle is a hypothetical subatomic particle proposed by Attila Krasznahorkay and his colleagues to explain certain anomalous measurement results. The particle has been proposed to explain wide angles observed in the trajectory paths of particles produced during a nuclear transition of beryllium-8 atoms and in stable helium atoms. The X17 particle could be the force carrier for a postulated fifth force, possibly connected with dark matter, and has been described as a protophobic (i.e., ignoring protons) X boson with a mass near 17Β MeV.

πŸ”— Smith Chart

πŸ”— Electronics

The Smith chart, invented by Phillip H. Smith (1905–1987), and T. Mizuhashi, is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits. The Smith chart can be used to simultaneously display multiple parameters including impedances, admittances, reflection coefficients, S n n {\displaystyle S_{nn}\,} scattering parameters, noise figure circles, constant gain contours and regions for unconditional stability, including mechanical vibrations analysis. The Smith chart is most frequently used at or within the unity radius region. However, the remainder is still mathematically relevant, being used, for example, in oscillator design and stability analysis. While the use of paper Smith charts for solving the complex mathematics involved in matching problems has been largely replaced by software based methods, the Smith charts display is still the preferred method of displaying how RF parameters behave at one or more frequencies, an alternative to using tabular information. Thus most RF circuit analysis software includes a Smith chart option for the display of results and all but the simplest impedance measuring instruments can display measured results on a Smith chart display.

πŸ”— Germany πŸ”— Bridges and Tunnels

The Magdeburg Water Bridge (German: KanalbrΓΌcke Magdeburg) is a large navigable aqueduct in central Germany, located near Magdeburg. The largest canal underbridge in Europe, it spans the river Elbe and directly connects the Mittellandkanal to the west and Elbe-Havel Canal to the east of the river, allowing large commercial ships to pass between the Rhineland and Berlin without having to descend into and then climb out of the Elbe itself.

πŸ”— Gyrocar

πŸ”— Russia πŸ”— Russia/technology and engineering in Russia πŸ”— Automobiles

A gyrocar is a two-wheeled automobile. The difference between a bicycle or motorcycle and a gyrocar is that in a bike, dynamic balance is provided by the rider, and in some cases by the geometry and mass distribution of the bike itself, and the gyroscopic effects from the wheels. Steering a motorcycle is done by precessing the front wheel. In a gyrocar, balance was provided by one or more gyroscopes, and in one example, connected to two pendulums by a rack and pinion.

The concept was originally described in fiction in 1911 "Two Boys in a Gyrocar: The story of a New York to Paris Motor Race" by Kenneth Brown, (Houghton Mifflin Co). However the first prototype Gyrocar, The Shilovski Gyrocar, was commissioned in 1912 by the Russian Count Pyotr Shilovsky, a lawyer and member of the Russian royal family. It was manufactured to his design by the Wolseley Tool and Motorcar Company in 1914 and demonstrated in London the same year. The gyrocar was powered by a modified Wolseley C5 engine of 16–20Β hp, with a bore of 90Β mm and a stroke of 121Β mm. It was mounted ahead of the radiator, driving the rear wheel through a conventional clutch and gear box. A transmission brake was fitted after the gearbox – there were no brakes on the wheels themselves. The weight of the vehicle was 2.75 tons and it had a very large turning radius.

In 1927 Louis Brennan, funded to the tune of Β£12,000 (plus a Β£2000 per year) by John Cortauld built a rather more successful gyrocar. Two contra-rotating gyros were housed under the front seats, spun in a horizontal plane at 3500 rpm by 24V electric motors powered from standard car batteries. This was the greatest speed obtainable with the electric motors available, and meant that each rotor had to weigh 200Β lb (91Β kg) to generate sufficient forces. Precession was in the vertical fore-aft plane. The car had a Morris Oxford engine, engine mountings, and gearbox. Two sidewheels (light aircraft tailwheels were used) were manually lowered on stopping; if the driver forgot and switched off the gyros and walked away, the car would continue to balance itself using the gyro momentum for a few minutes, and then the wheels would automatically be dropped to stop tipping.

πŸ”— Lockout-Tagout

πŸ”— Occupational Safety and Health

Lock Out, Tag Out (LOTO), Lock Out, Tag Out, Try Out (LOTOTO) or lock and tag is a safety procedure used in industry and research settings to ensure that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or repair work. It requires that hazardous energy sources be "isolated and rendered inoperative" before work is started on the equipment in question. The isolated power sources are then locked and a tag is placed on the lock identifying the worker who placed it. The worker then holds the key for the lock, ensuring that only he or she can remove the lock and start the machine. This prevents accidental startup of a machine while it is in a hazardous state or while a worker is in direct contact with it.

Lockout-tagout is used across industries as a safe method of working on hazardous equipment and is mandated by law in some countries.

πŸ”— Agglutinative Language

πŸ”— Linguistics πŸ”— Linguistics/Theoretical Linguistics

An agglutinative language is a type of synthetic language with morphology that primarily uses agglutination. Words may contain different morphemes to determine their meanings, but all of these morphemes (including stems and affixes) remain, in every aspect, unchanged after their unions. This results in generally more easily deducible word meanings if compared to fusional languages, which allow modifications in either or both the phonetics or spelling of one or more morphemes within a word. This usually results in a shortening of the word, or it provides easier pronunciation.

Agglutinative languages have generally one grammatical category per affix while fusional languages have multiple. The term was introduced by Wilhelm von Humboldt to classify languages from a morphological point of view. It is derived from the Latin verb agglutinare, which means "to glue together".

Non-agglutinative synthetic languages are fusional languages; morphologically, they combine affixes by "squeezing" them together, drastically changing them in the process, and joining several meanings in a single affix (for example, in the Spanish word comí "I ate", the suffix -í carries the meanings of first person, singular number, past tense, perfective aspect, indicative mood, active voice.) The term agglutinative is sometimes incorrectly used as a synonym for synthetic. Used in this way, the term embraces both fusional languages and inflected languages. The agglutinative and fusional languages are two ends of a continuum, with various languages falling more toward one or the other end. For example, Japanese is generally agglutinative, but displays fusion in otōto (弟, younger brother), from oto+hito (originally woto+pito), and in its non-affixing verb conjugations. A synthetic language may use morphological agglutination combined with partial usage of fusional features, for example in its case system (e.g., German, Dutch, and Persian).

Agglutinative languages tend to have a high rate of affixes or morphemes per word, and to be very regular, in particular with very few irregular verbs. For example, Japanese has very few irregular verbs – only two are significantly irregular, and there are only about a dozen others with only minor irregularity; Ganda has only one (or two, depending on how "irregular" is defined); while in the Quechua languages, all the ordinary verbs are regular. Korean has only ten irregular forms of conjugation except for the passive and causative conjugations. Georgian is an exception; it is highly agglutinative (with up to eight morphemes per word), but it has a significant number of irregular verbs with varying degrees of irregularity.
