The Siege of Caffa was a 14th-century military encounter when Jani Beg of the Golden Horde sieged the city of Caffa, (today Feodosia) between two periods in the 1340s. The city of Caffa, a Genoese colony, was a vital trading hub located in Crimea. The city was then part of Gazaria, a group of seven ports located in Crimea and belonging to the maritime empire of the Republic of Genoa. The event is historically significant primarily because it is believed to be one of the earliest instances of biological warfare.

The siege of Caffa was characterized by intense military tactics from both sides. After several years of siege, the armies of the Horde were forced to withdraw. The siege is famous for a story recounted by Italian notary Gabriel de Mussis, which attributed the subsequent spread of the Black Death to plague-infested corpses having been launched over the walls at the end of the siege.

The fog of war (German: Nebel des Krieges) is the uncertainty in situational awareness experienced by participants in military operations. The term seeks to capture the uncertainty regarding one's own capability, adversary capability, and adversary intent during an engagement, operation, or campaign. Military forces try to reduce the fog of war through military intelligence and friendly force tracking systems. The term has become commonly used to define uncertainty mechanics in wargames.

Norway is not a member state of the European Union (EU). However, it is associated with the Union through its membership in agreements in the European Economic Area (EEA) established in 1994, and by virtue of being a founding member of the European Free Trade Association (EFTA) which was founded in 1960, one of the two historically dominant western European trade blocs. Norway had considered joining the European Community and the European Union twice, but opted to decline following referendums in 1972 and 1994.

On 13 February 2017, the eldest son of Kim Jong-il and half-brother of Kim Jong-un, Kim Jong-nam, was attacked with the nerve agent VX at Kuala Lumpur International Airport in Malaysia. He had been exiled from North Korea in 2003 and had been living abroad.

Following his visit to the resort island Langkawi, Kim Jong-nam had arrived at terminal 2 sometime before 9:00 a.m. to take a 10:50 a.m. AirAsia flight to Macau. At approximately 9:00 a.m., two women attacked Kim Jong-nam with the VX nerve agent. He died about 15 to 20 minutes later.

The women were identified as Siti Aisyah, an Indonesian and Đoàn Thị Hương, a Vietnamese. Both were charged with the murder of Kim Jong-nam. The charges were dropped, although Hương pled guilty to "voluntarily causing hurt by dangerous weapons or means" and received a sentence of three years and four months. Four North Korean suspects left the airport shortly after the assassination and reached Pyongyang without being arrested. Other North Koreans were arrested but were released without charge.

It is widely believed that Kim Jong-nam was murdered on the orders of Kim Jong-un.

🔗 Novels

Celine's Laws are a series of three laws regarding government and social interaction attributed to the fictional character Hagbard Celine from Robert Anton Wilson's and Robert Shea's Illuminatus! Trilogy. Celine, a gentleman anarchist, serves as a mouthpiece for Wilson's libertarian, anarchist and sometimes completely uncategorizable ideas about the nature of humanity. Celine's Laws are outlined in the trilogy by a manifesto titled Never Whistle While You're Pissing. Wilson later goes on to elaborate on the laws in his nonfiction book, Prometheus Rising, as being inherent consequences of average human psychology.

A piece entitled Celine's Laws appears in Robert Anton Wilson's The Illuminati Papers, which features articles written by Wilson under the guise of many of his characters from The Illuminatus! Trilogy alongside interviews with the author himself. One article pulls from another, as well as from the original Trilogy.

Celine, in his manifesto, recognizes these are generalities, but also says that their basic principles can be used to find the source of every great decline and fall of nations, and goes on to claim they are as universal as Newton's Laws in applying to everything.

Phantom OS is an operating system mostly made by Russian programmers. Phantom OS is based on a concept of persistent virtual memory, and is managed-code oriented. Phantom OS is one of a few OSes that are not based on classical concepts of Unix-like systems. Its primary goal is to achieve simplicity and effectiveness in both the operating system and applications at the same time.

Phantom is based on the principle that "Everything is an object", in contrast to the Unix-like approach of "Everything is a file".

The Peirce quincuncial projection is a conformal map projection developed by Charles Sanders Peirce in 1879. The projection has the distinctive property that it can be tiled ad infinitum on the plane, with edge-crossings being completely smooth except for four singular points per tile. The projection has seen use in digital photography for portraying 360° views. The description quincuncial refers to the arrangement of four quadrants of the globe around the center hemisphere in an overall square pattern. Typically the projection is oriented such that the north pole lies at the center.

Sailing stones (also known as sliding rocks, walking rocks, rolling stones, and moving rocks), are a geological phenomenon where rocks move and inscribe long tracks along a smooth valley floor without human or animal intervention. The movement of the rocks occurs when large ice sheets a few millimeters thick and floating in an ephemeral winter pond start to break up during sunny days. Frozen during cold winter nights, these thin floating ice panels are driven by wind and shove rocks at speeds up to 5 meters per minute.

Trails of sliding rocks have been observed and studied in various locations, including Little Bonnie Claire Playa in Nevada, and most famously at Racetrack Playa, Death Valley National Park, California, where the number and length of tracks are notable.

The surprisingly popular answer is a wisdom of the crowd technique that taps into the expert minority opinion within a crowd. For a given question, a group is asked both "What do you think the right answer is?" and "What do you think the popular answer will be?" The answer that maximizes the average difference between the "right" answer and the "popular" answer is the "surprisingly popular" answer.

Sir Basil Zaharoff, GCB, GBE, born Vasileios Zacharias (Greek: Βασίλειος Zαχαρίας Ζαχάρωφ; October 6, 1849 – November 27, 1936), was a Greek arms dealer and industrialist. One of the richest men in the world during his lifetime, Zaharoff was described as a "merchant of death" and "mystery man of Europe". His success was forged through his cunning, often aggressive and sharp, business tactics. These included the sale of arms to opposing sides in conflicts, sometimes delivering fake or faulty machinery and skilfully using the press to attack business rivals.

Zaharoff maintained close contacts with many powerful political leaders, including British Prime Minister David Lloyd George, Greek Prime Minister Eleftherios Venizelos and Ottoman Sultan Abdul Hamid II; he served as a primary inspiration for Ian Fleming's fictional James Bond villain Ernst Stavro Blofeld.
