A charrette (American pronunciation: ), often Anglicized to charette or charet and sometimes called a design charrette, is an intense period of design or planning activity.

The word charrette may refer to any collaborative session in which a group of designers draft a solution to a design problem.

While the structure of a charrette varies, depending on the design problem and the individuals in the group, charrettes often take place in multiple sessions in which the group divides into sub-groups. Each sub-group then presents its work to the full group as material for further dialogue. Such charrettes serve as a way of quickly generating a design solution while integrating the aptitudes and interests of a diverse group of people. The general idea of a charrette is to create an innovative atmosphere in which a diverse group of stakeholders can collaborate to "generate visions for the future".

Sabbath mode, also known as Shabbos mode (Ashkenazi pronunciation) or Shabbat mode, is a feature in many modern home appliances, including ovens and refrigerators, which is intended to allow the appliances to be used (subject to various constraints) by Shabbat-observant Jews on the Shabbat and Jewish holidays. The mode usually overrides the usual, everyday operation of the electrical appliance and makes the operation of the appliance comply with the rules of Halakha (Jewish law).

Microformats (μF) are predefined HTML markup (like HTML classes) created to serve as descriptive and consistent metadata about elements, designating them as representing a certain type of data (such as contact information, geographic coordinates, events, products, recipes, etc.). They allow software to process the information reliably by having set classes refer to a specific type of data rather than being arbitrary.

Microformats emerged around 2005 and were predominantly designed for use by search engines, web syndication and aggregators such as RSS. Google confirmed in 2020 that it still parses microformats for use in content indexing. Microformats are referenced in several W3C social web specifications, including IndieAuth and Webmention.

Although the content of web pages has been capable of some "automated processing" since the inception of the web, such processing is difficult because the markup elements used to display information on the web do not describe what the information means. Microformats can bridge this gap by attaching semantics, and thereby obviating other, more complicated, methods of automated processing, such as natural language processing or screen scraping. The use, adoption and processing of microformats enables data items to be indexed, searched for, saved or cross-referenced, so that information can be reused or combined.

As of 2013, microformats allow the encoding and extraction of event details, contact information, social relationships and similar information.

Microformats2, abbreviated as mf2, is the updated version of microformats. Mf2 provides an easier way of interpreting HTML structured syntax and vocabularies than the earlier ways that made use of RDFa and microdata.

Anti-gay purges in the Chechen Republic, a part of the Russian Federation, have included forced disappearances — secret abductions, imprisonment, torture — and extrajudicial killing by authorities targeting persons based on their perceived sexual orientation. An unknown number of people, who authorities detained on suspicion of being gay or bisexual, have reportedly died after being held in what human rights groups and eyewitnesses have called concentration camps.

Allegations were initially reported on 1 April 2017 in Novaya Gazeta, a Russian-language opposition newspaper, which reported that since February 2017 over 100 men had allegedly been detained and tortured and at least three had died in an extrajudicial killing. The paper, citing its sources in the Chechen special services, called the wave of detentions a "prophylactic sweep". The journalist who first reported on the subject went into hiding. There have been calls for reprisals against journalists who report on the situation.

As news spread of Chechen authorities' actions, which have been described as part of a systematic anti-LGBT purge, Russian and international activists scrambled to evacuate survivors of the camps and other vulnerable Chechens but were met with difficulty obtaining visas to conduct them safely beyond Russia.

The reports of the persecution were met with a variety of reactions worldwide. The Head of the Chechen Republic Ramzan Kadyrov denied not only the occurrence of any persecution but also the existence of gay men in Chechnya, adding that such people would be killed by their own families. Officials in Moscow were skeptical, although in late May the Russian government reportedly agreed to send an investigative team to Chechnya. Numerous national leaders and other public figures in the West condemned Chechnya's actions, and protests were held in Russia and elsewhere. A report released in December 2018 by the Organization for Security and Cooperation in Europe (OSCE) confirmed claims that persecution of LGBT persons had taken place and was ignored by authorities.

On 11 January 2019, it was reported that another 'gay purge' had begun in the country in December 2018, with several gay men and women being detained. The Russian LGBT Network believes that around 40 persons were detained and two killed.

The Kee Bird was a United States Army Air Forces Boeing B-29 Superfortress, serial 45-21768, of the 46th Reconnaissance Squadron, that became marooned after making an emergency landing in northwest Greenland during a secret Cold War spying mission on 21 February 1947. While the entire crew was safely evacuated after spending three days in the isolated Arctic tundra, the aircraft itself was left at the landing site. It lay there undisturbed until 1994, when a privately funded mission was launched to repair and return it. During the attempted recovery, a fire broke out, resulting in the destruction and loss of the airframe on the ground.

🔗 Economics 🔗 Taxation

A land value tax (LVT) is a levy on the value of land without regard to buildings, personal property and other improvements. It is also known as a location value tax, a site valuation tax, split rate tax, or a site-value rating,

Land value taxes are generally favored by economists as they do not cause economic inefficiency, and reduce inequality. A land value tax is a progressive tax, in that the tax burden falls on land owners, because land ownership is correlated with wealth and income. The land value tax has been referred to as "the perfect tax" and the economic efficiency of a land value tax has been accepted since the eighteenth century. Economists since Adam Smith and David Ricardo have advocated this tax because it does not hurt economic activity or discourage or subsidize development.

LVT is associated with Henry George, whose ideology became known as Georgism. George argued that taxing the land value is most logical source of public revenue because the supply of land is fixed and because public infrastructure improvements would be reflected in (and thus paid for) by increased land values.

Land value taxation is currently implemented throughout Denmark, Estonia, Lithuania, Russia, Singapore, and Taiwan; it has also been applied to lesser extents in parts of Australia, Mexico (Mexicali), and the United States (e.g., Pennsylvania).

🔗 Internet culture

I Can Eat Glass was a linguistic project documented on the early Web by then-Harvard student Ethan Mollick. The objective was to provide speakers with translations of the phrase "I can eat glass, it does not hurt me" from a wide variety of languages; the phrase was chosen because of its unorthodox nature. Mollick's original page disappeared in or about June 2004.

As Mollick explained, visitors to a foreign country have "an irresistible urge" to say something in that language, and whatever they say usually marks them as tourists immediately. Saying "I can eat glass, it does not hurt me", however, ensures that the speaker "will be viewed as an insane native, and treated with dignity and respect".

The project grew to considerable size since web surfers were invited to submit translations. The phrase was translated into over 150 languages, including some that are fictional or invented, as well as into code from various computer languages. It became an Internet meme.

🔗 Aviation 🔗 Aviation/aircraft

A propfan, also called an open rotor engine, or unducted fan, is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop. A propfan is typically designed with a large number of short, highly twisted blades, similar to a turbofan's bypass compressor (the fan itself). For this reason, the propfan has been variously described as an "unducted fan" or an "ultra-high-bypass (UHB) turbofan."

🔗 Computing

Constraint logic programming is a form of constraint programming, in which logic programming is extended to include concepts from constraint satisfaction. A constraint logic program is a logic program that contains constraints in the body of clauses. An example of a clause including a constraint is A(X,Y) :- X+Y>0, B(X), C(Y). In this clause, X+Y>0 is a constraint; A(X,Y), B(X), and C(Y) are literals as in regular logic programming. This clause states one condition under which the statement A(X,Y) holds: X+Y is greater than zero and both B(X) and C(Y) are true.

As in regular logic programming, programs are queried about the provability of a goal, which may contain constraints in addition to literals. A proof for a goal is composed of clauses whose bodies are satisfiable constraints and literals that can in turn be proved using other clauses. Execution is performed by an interpreter, which starts from the goal and recursively scans the clauses trying to prove the goal. Constraints encountered during this scan are placed in a set called constraint store. If this set is found out to be unsatisfiable, the interpreter backtracks, trying to use other clauses for proving the goal. In practice, satisfiability of the constraint store may be checked using an incomplete algorithm, which does not always detect inconsistency.

🔗 Video games 🔗 Video games/Nintendo

The video game crash of 1983 (known as the Atari shock in Japan) was a large-scale recession in the video game industry that occurred from 1983 to 1985, primarily in the United States. The crash was attributed to several factors, including market saturation in the number of game consoles and available games, and waning interest in console games in favor of personal computers. Revenues peaked at around $3.2 billion in 1983, then fell to around $100 million by 1985 (a drop of almost 97 percent). The crash abruptly ended what is retrospectively considered the second generation of console video gaming in North America.

Lasting about two years, the crash shook the then-booming industry, and led to the bankruptcy of several companies producing home computers and video game consoles in the region. Analysts of the time expressed doubts about the long-term viability of video game consoles and software.

The North American video game console industry eventually recovered a few years later, mostly due to the widespread success of the Nintendo Entertainment System (NES) in 1985; Nintendo designed the NES as the Western branding for its Famicom console originally released in 1983 in order to avoid the missteps which caused the 1983 crash and avoid the stigma which video games had at that time.
