The Trans-African Highway network comprises transcontinental road projects in Africa being developed by the United Nations Economic Commission for Africa (UNECA), the African Development Bank (ADB), and the African Union in conjunction with regional international communities. They aim to promote trade and alleviate poverty in Africa through highway infrastructure development and the management of road-based trade corridors. The total length of the nine highways in the network is 56,683 km (35,221 mi).

In some documents the highways are referred to as "Trans-African Corridors" or "Road Corridors" rather than highways. The name Trans-African Highway and its variants are not in wide common usage outside of planning and development circles, and as of 2014 one does not see them signposted as such or labelled on maps, except in Kenya and Uganda where the Mombasa–Nairobi–Kampala–Fort Portal section (or the Kampala–Kigali feeder road) of Trans-African Highway 8 is sometimes referred to as the "Trans-Africa Highway".

It's often said that Wikipedia is dying. This is the latest in a long line of technological deaths. Earlier, the WikiWikiWeb died. Before that, Usenet died.

Reasons why Wikipedia is dying include and may not be limited to:

• most of the major editors are leaving
• most edits are now made by robots
• article syntax is too complicated for readers and new editors
• pop culture articles are longer than science or history articles
• power-hungry administrators are warring against content creators so they can delete everything and rule a perfect, empty wiki [Is this right? -- Ed.]
• the people with the most time to edit are also those with the most time and inclination to argue in perpetuity
• the Great Space Wombat said it is dying
• bias is going to destroy the entire neutral point of view we uphold so much
• vandalism. No elaboration required.
• the WMF is more corrupt than governments
• discussion here is more toxic than on Twitter
• nobody is donating (why else do they keep asking for money?)
• people will stop visiting the main site and just get blurbs from search engines or chatbots instead
• insert additional reasons here

Wikipedia has been dying since at least 100 years ago.

🔗 Medicine 🔗 China 🔗 Plants 🔗 Pharmacology 🔗 Psychoactive and Recreational Drugs

For over two millennia, texts in Chinese herbology and traditional Chinese medicine have recorded medicinal plants that are also hallucinogens and psychedelics. Some are familiar psychoactive plants in Western herbal medicine (e.g., Chinese: 莨菪; pinyin: làngdàng, i.e. Hyoscyamus niger), but several Chinese plants have not been noted as hallucinogens in modern works (e.g.,Chinese: 雲實; pinyin: yúnshí; lit. 'cloud seed', i.e. Caesalpinia decapetala). Chinese herbals are an important resource for the history of botany, for instance, Zhang Hua's c. 290 Bowuzhi is the earliest record of the psilocybin mushroom xiàojùn 笑菌 (lit. "laughing mushroom", i.e. Gymnopilus junonius).

🔗 Chess

The Immortal Game was a chess game played by Adolf Anderssen and Lionel Kieseritzky on 21 June 1851 in London, during a break of the first international tournament. The bold sacrifices made by Anderssen to secure victory have made it one of the most famous chess games of all time. Anderssen gave up both rooks and a bishop, then his queen, checkmating his opponent with his three remaining minor pieces. In 1996, Bill Hartston called the game an achievement "perhaps unparalleled in chess literature".

A warrant canary is a method by which a communications service provider aims to inform its users that the provider has been served with a government subpoena despite legal prohibitions on revealing the existence of the subpoena. The warrant canary typically informs users that there has not been a court-issued subpoena as of a particular date. If the canary is not updated for the period specified by the host or if the warning is removed, users are to assume that the host has been served with such a subpoena. The intention is to allow the provider to warn users of the existence of a subpoena passively, without technically violating the court order not to do so.

Some subpoenas, such as those covered under 18 U.S.C. §2709(c) of the USA Patriot Act, provide criminal penalties for disclosing the existence of the subpoena to any third party, including the service provider's users.

National Security Letters (NSL) originated in the 1986 Electronic Communications Privacy Act and originally targeted those suspected of being agents of a foreign power. Targeting agents of a foreign power was revised in 2001 under the Patriot Act to allow NSLs to target those who may have information deemed relevant to both counterintelligence activities directed against the United States and terrorism. The idea of using negative pronouncements to thwart the nondisclosure requirements of court orders and served secret warrants was first proposed by Steven Schear on the cypherpunks mailing list, mainly to uncover targeted individuals at ISPs. It was also suggested for and used by public libraries in 2002 in response to the USA Patriot Act, which could have forced librarians to disclose the circulation history of library patrons.

🔗 United States 🔗 Skepticism 🔗 United States/Washington - Seattle 🔗 United States/Washington

The Seattle windshield pitting epidemic is a phenomenon which affected Bellingham, Seattle, and other communities of Washington state in April, 1954; it is considered an example of a mass delusion. It was characterized by widespread observation of previously unnoticed windshield holes, pits and dings, leading residents to believe that a common causative agent was at work. It was originally thought to be the work of vandals but the rate of pitting was so great that residents began to attribute it to everything from sand flea eggs to nuclear bomb testing.

Originating in Bellingham in March, police initially believed the work to be vandals using BB guns. However the pitting was soon observed in the nearby towns of Sedro Woolley and Mount Vernon and by mid-April, appeared to have spread to the town of Anacortes on Fidalgo Island.

Within a week, the news and the so-called "pitting epidemic" had reached metropolitan Seattle. As the newspapers began to feature the story, more and more reports of pitting were called in. Motorists began stopping police cars to report damage. Car lots and parking garages reported particularly severe attacks.

Several hypotheses for the widespread damage were postulated:

• Some thought that a new million-watt radio transmitter at nearby Jim Creek Naval Radio Station was producing waves that caused physical oscillations in glass;
• Some believed it to be the work of cosmic rays;
• Some reported seeing glass bubbles form right before their eyes, believing it to be the work of sand fleas.

By April 15, close to 3,000 windshields had been reported as affected. Mayor Allan Pomeroy contacted Washington Governor Arthur B. Langlie, then President Dwight D. Eisenhower asking for assistance.

Finally, Sergeant Max Allison of the Seattle police crime laboratory stated that the pitting reports consisted of "5 per cent hoodlum-ism, and 95 per cent public hysteria." By April 17, the pitting suddenly stopped.

The "Seattle Windshield Pitting Epidemic" as it is called has become a textbook case of collective delusion (not "mass hysteria" as reported). Although natural windshield pitting had been going on for some time, it was only when the media called public attention to it that people actually looked at their windshields and saw damage they had never noticed before.

Non-explosive demolition agents are chemicals that are an alternative to explosives and gas pressure blasting products in demolition, mining, and quarrying. To use non-explosive demolition agents in demolition or quarrying, holes are drilled in the base rock as they would be for use with conventional explosives. A slurry mixture of the non-explosive demolition agent and water is poured into the drill holes. Over the next few hours the slurry expands, cracking the rock in a pattern somewhat like the cracking that would occur from conventional explosives.

Non-explosive demolition agents offer many advantages including that they are silent and do not produce vibration the way a conventional explosive would. In some applications conventional explosives are more economical than non-explosive demolition agents. In many countries these are available without restriction, unlike explosives which are highly regulated.

The active ingredient is typically calcium oxide, "burnt lime," and is typically mixed with Portland cement and modifiers.

These agents are much safer than explosives, but they have to be used as directed to avoid steam explosions during the first few hours after being placed.

Many patents describe non-explosive demolition agents containing CaO, SiO₂ and/or cement.

The Thousand Character Classic (Chinese: 千字文; pinyin: Qiānzì Wén), also known as the Thousand Character Text, is a Chinese poem that has been used as a primer for teaching Chinese characters to children from the sixth century onward. It contains exactly one thousand characters, each used only once, arranged into 250 lines of four characters apiece and grouped into four line rhyming stanzas to make it easy to memorize. It is sung, much as children learning the Latin alphabet sing an "alphabet song." Along with the Three Character Classic and the Hundred Family Surnames, it has formed the basis of literacy training in traditional China.

The first line is Tian di xuan huang (traditional Chinese: 天地玄黃; simplified Chinese: 天地玄黄; pinyin: Tiāndì xuán huáng; Jyutping: tin1 dei6 jyun4 wong4; lit. 'Heaven and Earth Dark and Yellow') and the last line, Yan zai hu ye (焉哉乎也; Yān zāi hū yě; yin1 zoi1 fu4 jaa5) explains the use of the grammatical particles "yan", "zai", "hu", and "ye".

The Pizza Meter refers to sudden increases of pizza orders from U.S. government offices, such as the White House and The Pentagon, before large events such as the Iraqi invasion of Kuwait, the Panama Invasion, and the Grenada invasion.

On the night of August 1, 1990, the night before the Iraqi invasion of Kuwait, military personnel at The Pentagon came together to discuss issues in the Middle East. According to Frank Meeks, the owner of Washington, D.C.'s Domino's Pizza franchise of 45 restaurants, the CIA ordered a record-breaking 21 pizzas from Domino's that night. Between January 7 to January 16, 1991, the number of pizza deliveries to the Pentagon past 10 p.m reached 101, with another 55 pizzas delivered to the White House on January 16 between 10 p.m. and 2 a.m.

Meeks tied the influx of pizza orders from the Pentagon, White House, and the CIA to oncoming major announcements from the White House, publicizing his observations. Consequently, the public nicknamed the event "The Pizza Meter". Shortly after Meeks' comments were released, government offices no longer ordered from Domino's branches in Washington, opting to buy pizza at separate times or at different pizza joints.
