🔗 France

La Bougie du Sapeur (French: [la bu.ʒi dy sa.pœʁ]) is a French satirical newspaper launched in 1980 that is published only on Leap Day, making it the world's least frequently published newspaper. The editor-in-chief is Jean d'Indy, who works for France Galop and has been involved in producing the paper since 1992.

🔗 Law 🔗 English Language

"The exception that proves the rule" (sometimes "the exception proves the rule") is a saying whose meaning is contested. Henry Watson Fowler's Modern English Usage identifies five ways in which the phrase has been used, and each use makes some sort of reference to the role that a particular case or event takes in relation to a more general rule.

Two original meanings of the phrase are usually cited. The first, preferred by Fowler, is that the presence of an exception applying to a specific case establishes ("proves") that a general rule exists. A more explicit phrasing might be "the exception that proves the existence of the rule." Most contemporary uses of the phrase emerge from this origin, although often in a way which is closer to the idea that all rules have their exceptions. The alternative origin given is that the word "prove" is used in the archaic sense of "test". In this sense, the phrase does not mean that an exception demonstrates a rule to be true or to exist, but that it tests the rule, thereby proving its value. There is little evidence of the phrase being used in this second way.

🔗 Star Trek

Star Trek Continues is an American fan-made web series set in the Star Trek universe. Produced by the nonprofit charity Trek Continues, Inc. and Dracogen, and initially co-produced by Far from Home LLC and Farragut Films, the series consists of 11 episodes released between 2013 and 2017. The series is an unofficial direct continuation of Star Trek: The Original Series, and emulates its visual and storytelling features to achieve the same look and feel. Those who made the show have said in interviews that the intent was to finish the original five-year mission of the show, and this is borne out in the plot lines of the final two episodes.

The series was fan-created and all episodes were released to watch on YouTube. As with all such Star Trek fan productions, use of copyrighted and trademarked properties from the original series was allowed so long as the production was not commercial. A portion of the funds necessary to produce the episodes was raised through successful Kickstarter and Indiegogo campaigns, to which thousands of backers contributed.

Star Trek Continues won a Webby Award for "People's Choice – Long Form Drama" in 2016, a Geekie Award for "Best Web Series" in 2014, and numerous Telly and Accolade awards. The series was very positively received by critics, who praised the quality of the production and stated that the show set a new standard for Star Trek fan films.

After the 11th episode was released in late 2017, the Star Trek Continues series ended.

🔗 Mathematics 🔗 Germany 🔗 Germany/Prussia

The Seven Bridges of Königsberg is a historically notable problem in mathematics. Its negative resolution by Leonhard Euler in 1736 laid the foundations of graph theory and prefigured the idea of topology.

The city of Königsberg in Prussia (now Kaliningrad, Russia) was set on both sides of the Pregel River, and included two large islands—Kneiphof and Lomse—which were connected to each other, or to the two mainland portions of the city, by seven bridges. The problem was to devise a walk through the city that would cross each of those bridges once and only once.

By way of specifying the logical task unambiguously, solutions involving either

1. reaching an island or mainland bank other than via one of the bridges, or
2. accessing any bridge without crossing to its other end

are explicitly unacceptable.

Euler proved that the problem has no solution. The difficulty he faced was the development of a suitable technique of analysis, and of subsequent tests that established this assertion with mathematical rigor.

A zip bomb, also known as a zip of death or decompression bomb, is a malicious archive file designed to crash or render useless the program or system reading it. It is often employed to disable antivirus software, in order to create an opening for more traditional viruses.

Rather than hijacking the normal operation of the program, a zip bomb allows the program to work as intended, but the archive is carefully crafted so that unpacking it (e.g. by a virus scanner in order to scan for viruses) requires inordinate amounts of time, disk space or memory.

Most modern antivirus programs can detect whether a file is a zip bomb, to avoid unpacking it.

🔗 Climate change 🔗 Environment 🔗 Meteorology 🔗 Urban studies and planning

An urban heat island (UHI) is an urban area or metropolitan area that is significantly warmer than its surrounding rural areas due to human activities. The temperature difference is usually larger at night than during the day, and is most apparent when winds are weak. UHI is most noticeable during the summer and winter. The main cause of the urban heat island effect is from the modification of land surfaces. Waste heat generated by energy usage is a secondary contributor. As a population center grows, it tends to expand its area and increase its average temperature. The term heat island is also used; the term can be used to refer to any area that is relatively hotter than the surrounding, but generally refers to human-disturbed areas.

Monthly rainfall is greater downwind of cities, partially due to the UHI. Increases in heat within urban centers increases the length of growing seasons, and decreases the occurrence of weak tornadoes. The UHI decreases air quality by increasing the production of pollutants such as ozone, and decreases water quality as warmer waters flow into area streams and put stress on their ecosystems.

Not all cities have a distinct urban heat island, and the heat island characteristics depend strongly on the background climate of the area in which the city is located. Mitigation of the urban heat island effect can be accomplished through the use of green roofs and the use of lighter-colored surfaces in urban areas, which reflect more sunlight and absorb less heat.

Concerns have been raised about possible contribution from urban heat islands to global warming. While some lines of research did not detect a significant impact, other studies have concluded that heat islands can have measurable effects on climate phenomena at the global scale.

🔗 Internet 🔗 Computing 🔗 Computing/Computer Security 🔗 Computing/Websites 🔗 Computing/Networking

Domain fronting is a technique for Internet censorship circumvention that uses different domain names in different communication layers of an HTTPS connection to discreetly connect to a different target domain than is discernable to third parties monitoring the requests and connections.

Due to quirks in security certificates, the redirect systems of the content delivery networks (CDNs) used as 'domain fronts', and the protection provided by HTTPS, censors are typically unable to differentiate circumvention ("domain-fronted") traffic from overt non-fronted traffic for any given domain name. As such they are forced to either allow all traffic to the domain front—including circumvention traffic—or block the domain front entirely, which may result in expensive collateral damage and has been likened to "blocking the rest of the Internet".

Domain fronting does not conform to HTTP standards that require the SNI extension and HTTP Host header to contain the same domain. Many large cloud service providers, including Amazon, Microsoft, and Google, actively prohibit domain fronting, which has limited it as a censorship bypass technique. Pressure from censors in Russia and China is thought to have contributed to these prohibitions, but domain fronting can also be used maliciously.

A newer variant of domain fronting, domain hiding, passes an encrypted request for one resource (say, a website), concealed behind an unencrypted (plaintext) request for another resource whose DNS records are stored in the same cloud. It has much the same effect. Refraction networking is an application of the broader principle.

Modafinil, sold under the brand name Provigil among others, is a medication to treat sleepiness due to narcolepsy, shift work sleep disorder, or obstructive sleep apnea. While it has seen off-label use as a purported cognitive enhancer, the research on its effectiveness for this use is not conclusive. It is taken by mouth.

Common side effects include headache, anxiety, trouble sleeping, and nausea. Serious side effects may include allergic reactions such as anaphylaxis, Stevens–Johnson syndrome, misuse, and hallucinations. It is unclear if use during pregnancy is safe. The amount of medication used may need to be adjusted in those with kidney or liver problems. It is not recommended in those with an arrhythmia, significant hypertension, or left ventricular hypertrophy. How it works is not entirely clear. One possibility is that it may affect the areas of the brain involved with the sleep cycle.

Modafinil was approved for medical use in the United States in 1998. In the United States it is classified as a schedule IV controlled substance. In the United Kingdom it is a prescription only medication. It is available as a generic medication. In the United Kingdom it costs the NHS about £105.21 a month as of 2018. In the United States the wholesale cost per month is about US$34.20 as of 2018. In 2016, it was the 284th most prescribed medication in the United States, with more than a million prescriptions.

🔗 New Zealand 🔗 Maps

New Zealand has often been omitted from maps of the world, which has caught the attention of New Zealanders. It is considered that this is because of the widespread use of the Mercator projection, a map projection putting Europe in the center which leaves New Zealand in the bottom right-hand corner of maps, sometimes making it go overlooked by mapmakers, easily removed by an accidental crop, or simply not added for convenience, ignorance or laziness.

New Zealand has been excluded from maps at the National Museum of Natural History in Washington, D.C. in the United States, in IKEA stores, on the map of the board games Pandemic and Risk, on the map of the 2014 Nuclear Security Summit in which Prime Minister of New Zealand John Key participated, at a world map seal at the United Nations Office at Geneva in Switzerland, on the newspaper Daily Mail, on Government Executive's newsletter Defense One, on the magazine Forbes, on the digital media platform Mashable, on the Pyongyang International Airport in North Korea and on the logo of the Flat Earth Society. It was also excluded from maps promoting the 2015 Rugby World Cup even though New Zealand was the then world champion.

This recurrent occurrence has become a meme for New Zealanders. There is a community on Tumblr titled World Maps Without New Zealand and a Reddit community known as r/MapsWithoutNZ both focused on this issue with 10,000 and 30,000 members respectively as of 2017. In 2019, a user in r/MapsWithoutNZ noticed that a map, "BJÖRKSTA world map", on sale for 30 dollars at an IKEA store on Washington, D.C., did not portray New Zealand. Subsequently, IKEA apologized and removed the product from its stores. On Reddit, there also are communities about the omission of Flevoland in the Netherlands, Hawaii in the United States and Tasmania in Australia from world maps.

The New Zealand Government has acknowledged this phenomenon, and it features a map of the world in which the country is deliberately not included on the 404 error page of its official website; the page states that "something's missing". Furthermore, in 2018, a tourism campaign video was published in which the Prime Minister of New Zealand Jacinda Ardern and the New Zealander actor and comedian Rhys Darby discussed why New Zealand was being left off world maps. On the video, Darby jokingly said that it was the result of a conspiracy against New Zealand. The video promoted the hashtag #getnzonthemap.
