🔗 Musical Instruments 🔗 Electronic music

The Ondioline is an electronic keyboard instrument, invented in 1941 by the Frenchman Georges Jenny, and is a forerunner of today's synthesizers. It is sometimes called the "Jenny Ondioline."

The Ondioline is capable of creating a wide variety of sounds. Its keyboard has an unusual feature: it is suspended on special springs which makes it possible to introduce a natural vibrato if the player moves the keyboard (not the entire instrument) from side to side (laterally) with their playing hand. The result is an almost human-like vibrato that lends a wide range of expression to the Ondioline. The keyboard is also pressure-sensitive, and the instrument has a knee volume lever, as well.

The firehose of falsehood, or firehosing, is a propaganda technique in which a large number of messages are broadcast rapidly, repetitively, and continuously over multiple channels (such as news and social media) without regard for truth or consistency. Since 2014, when it was successfully used by Russia during its annexation of Crimea, this model has been adopted by other governments and political movements around the world.

🔗 Languages 🔗 Argentina 🔗 Wales

Patagonian Welsh (Welsh: Cymraeg y Wladfa) is a variety of the Welsh language spoken in the Patagonia region's Y Wladfa, Welsh settlements located in Chubut Province, Argentina. Though Patagonian Welsh is distinct from the several dialects used in Wales itself, the dialects have a high degree of mutual intelligibility, and speakers from Wales and Patagonia are able to communicate readily. Numerous toponyms throughout the Chubut Valley are of Welsh origin.

Teachers are sent from Wales to teach the language and to train local tutors in the Welsh language. There is some prestige in knowing the language, even among those not of Welsh descent. Welsh education and projects are mainly funded by the Welsh Government, British Council, Cardiff University and the Welsh–Argentine Association. In 2005, there were 62 Welsh classes in the area and Welsh was taught as a subject in two primary schools and two colleges in the region of Gaiman. There is also a bilingual Welsh–Spanish language school called Ysgol yr Hendre situated in Trelew, and a college located in Esquel. In 2016, there were three bilingual Welsh–Spanish primary schools in Patagonia.

In 2024–25, the number of registered learners—encompassing students in schools and adult programs—reached 1106, a significant increase from 623 in 2020.

The formal Eisteddfod poetry competitions have been revived, and are now bilingual in Welsh and Spanish.

In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate a very long string. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done efficiently.

🔗 Sanitation

A bidet shower—also known as a handheld bidet, commode shower, toilet shower, health faucet, bum shower, shatafa (from the Arabic: شَطَّافَة [ʃɑtˤˈtˤɑːfɑ], "rinser") or bum gun—is a hand-held triggered nozzle that is placed near the toilet and delivers a spray of water used for anal cleansing and cleaning of the genitals after using the toilet for defecation and urination, popularised by Arab nations where the bidet shower is a common bathroom accessory. The device is similar to that of a kitchen sink sprayer.

In predominantly Catholic countries, the Muslim world, in the Eastern Orthodox and Hindu cultures, and in some Protestant countries such as Finland, water is usually used for anal cleansing, using a jet (bidet shower, bidet) or vessel, and a person's hand (in some places only the left hand is used).

The two envelopes problem, also known as the exchange paradox, is a brain teaser, puzzle, or paradox in logic, probability, and recreational mathematics. It is of special interest in decision theory, and for the Bayesian interpretation of probability theory. Historically, it arose as a variant of the necktie paradox. The problem typically is introduced by formulating a hypothetical challenge of the following type:

It seems obvious that there is no point in switching envelopes as the situation is symmetric. However, because you stand to gain twice as much money if you switch while risking only a loss of half of what you currently have, it is possible to argue that it is more beneficial to switch. The problem is to show what is wrong with this argument.

The cantu a tenòre (Sardinian: su tenòre, su cuncòrdu, su cuntràttu, su cussèrtu, s'agorropamèntu, su cantu a pròa; Italian: canto a tenore) is a style of polyphonic folk singing characteristic of the island of Sardinia (Italy's second largest island), particularly the region of Barbagia, though some other Sardinian sub-regions bear examples of such tradition.

In 2005, UNESCO proclaimed the cantu a tenore to be an example of intangible cultural heritage.

In an attempt to prove to a group of prospective articling students that the building's glass windows were unbreakable — a stunt he had performed without incident many times before — he threw his body against the glass; however, this time the entire window frame gave way, and Hoy fell to his death.
