SN 1006 was a supernova that is likely the brightest observed stellar event in recorded history, reaching an estimated −7.5 visual magnitude, and exceeding roughly sixteen times the brightness of Venus. Appearing between April 30 and May 1, 1006 AD in the constellation of Lupus, this "guest star" was described by observers across the modern day countries of China, Japan, Iraq, Egypt, and the continent of Europe, and possibly recorded in North American petroglyphs. Some reports state it was clearly visible in the daytime. Modern astronomers now consider its distance from Earth to be about 7,200 light-years.

Winnie-the-Pooh (1926) is the first volume of stories about Winnie-the-Pooh, written by A. A. Milne and illustrated by E. H. Shepard. The book focuses on the adventures of a teddy bear called Winnie-the-Pooh and his friends Piglet, a small toy pig; Eeyore, a toy donkey; Owl, a live owl; and Rabbit, a live rabbit. The characters of Kanga, a toy kangaroo, and her son Roo are introduced later in the book, in the chapter entitled "In Which Kanga and Baby Roo Come to the Forest and Piglet has a Bath". The bouncy toy-tiger character of Tigger is not introduced until the sequel, The House at Pooh Corner.

In 2003, Winnie the Pooh was listed at number 7 on the BBC's survey The Big Read.

This is a list of serious injuries and deaths in which one or more subjects of a selfie were killed or injured, either before, during or after having taken a photo of themselves, with the accident at least in part attributed to the taking of the photo.

The United States Department of Transportation estimated that during 2014, the so-called "year of the selfie", 33,000 people were injured while driving and using a cell-phone in some fashion, which can include talking, listening, and "manual button/control actuation" including taking, uploading, downloading, editing, or opening of selfies. A 2015 survey by Erie Insurance Group found that 4% of all drivers admitted to taking selfies while driving.

The Washington Post reported in January 2016 that "about half" of at least 27 "selfie related" deaths in 2015 had occurred in India. No official datasets on the number of people who died taking selfies in India exists, but reports show from 2014 up to August 2016, there have been at least 54 deaths in India while taking selfies. The Indian Ministry of Tourism asked states to identify and barricade 'selfie danger' areas, its first national attempt to deal with the selfie deaths. Mumbai Police identified at least 16 danger zones after a man drowned attempting to save a selfie-taker. No-selfie zones were also established in certain areas of the Kumbh Mela because organizers feared bottlenecks caused by selfie-takers could spark stampedes.

A 2018 study of news reports showed that between October 2011 and November 2017, there were 259 selfie deaths in 137 incidents reported globally, with the highest occurrences in India, followed by Russia, United States, and Pakistan. The mean age was 23 years old, with male deaths outnumbering female about three to one.

Gary Stephen Webb (August 31, 1955 – December 10, 2004) was an American investigative journalist.

He began his career working for newspapers in Kentucky and Ohio, winning numerous awards, and building a reputation for investigative writing. Hired by the San Jose Mercury News, Webb contributed to the paper's Pulitzer Prize-winning coverage of the Loma Prieta earthquake.

Webb is best known for his "Dark Alliance" series, which appeared in The Mercury News in 1996. The series examined the origins of the crack cocaine trade in Los Angeles and claimed that members of the anti-communist Contra rebels in Nicaragua had played a major role in creating the trade, using cocaine profits to finance their fight against the government in Nicaragua. It also stated that the Contras may have acted with the knowledge and protection of the Central Intelligence Agency (CIA). The series provoked outrage, particularly in the Los Angeles African-American community, and led to four major investigations of its charges.

The Los Angeles Times and other major papers published articles suggesting the "Dark Alliance" claims were overstated and, in November 1996, Jerome Ceppos, the executive editor at Mercury News, wrote about being "in the eye of the storm". In May 1997, after an internal review, Ceppos stated that, although the story was correct on many important points, there were shortcomings in the writing, editing, and production of the series. He wrote that the series likely "oversimplified" the crack epidemic in America and the supposed "critical role" the dealers written about in the series played in it. Webb disagreed with this conclusion.

Webb resigned from The Mercury News in December 1997. He became an investigator for the California State Legislature, published a book based on the "Dark Alliance" series in 1998, and did freelance investigative reporting. He died by suicide on December 10, 2004.

The "Dark Alliance" series remains controversial. Critics view the series' claims as inaccurate or overstated, while supporters point to the results of a later CIA investigation as vindicating the series. The follow-up reporting in the Los Angeles Times and other papers has been criticised for focusing on problems in the series rather than re-examining the earlier CIA-Contra claims.

The Salisbury cathedral clock is a large iron-framed tower clock without a dial, in Salisbury Cathedral, England. Supposedly dating from about 1386, it is a well-preserved example of the earliest type of mechanical clock, called verge and foliot clocks, and is said to be the oldest working clock in the world, although similar claims are made for other clocks. Previously in a bell-tower which was demolished in 1790, the clock was restored to working condition in 1956 and is on display in the North nave aisle of the cathedral, close to the West front.

Mass killings under communist regimes occurred throughout the 20th century. Death estimates vary widely, depending on the definitions of the deaths that are included in them. The higher estimates of mass killings account for the crimes that governments committed against civilians, including executions, the destruction of populations through man-made hunger and deaths that occurred during forced deportations and imprisonment, and deaths that resulted from forced labor.

In addition to "mass killings," terms that are used to define such killings include "democide", "politicide", "classicide", and "genocide."

🔗 Cryptography 🔗 Cryptography/Computer science 🔗 Citizendium Porting

Kerckhoffs's principle (also called Kerckhoffs's desideratum, assumption, axiom, doctrine or law) of cryptography was stated by Netherlands born cryptographer Auguste Kerckhoffs in the 19th century: A cryptosystem should be secure even if everything about the system, except the key, is public knowledge.

Kerckhoffs's principle was reformulated (or possibly independently formulated) by American mathematician Claude Shannon as "the enemy knows the system", i.e., "one ought to design systems under the assumption that the enemy will immediately gain full familiarity with them". In that form, it is called Shannon's maxim. This concept is widely embraced by cryptographers, in contrast to "security through obscurity", which is not.

Free Beer, originally known as Vores øl - An open source beer (Danish for: Our Beer), is the first brand of beer with an "open"/"free" brand and recipe. The recipe and trademark elements are published under the Creative Commons CC BY-SA license.

The beer was created in 2004 by students at the IT University in Copenhagen together with artist collective Superflex, to illustrate how concepts of the FOSS movement might be applied outside the digital world. The "Free Beer" concept illustrates also the connection between the long tradition of freely sharing cooking recipes with the FOSS movement, which tries to establish this sharing tradition also for the "recipes" of software, the source code. The "Free beer" concept received an overall positive reception from international press and media for the political message, was presented on many exhibitions and conferences, and inspired many breweries in adopting the concept.

Bob's Game (stylized as "bob's game") was a role-playing video game being developed by independent video game developer Robert Pelloni since 2003/2004. The project is most notable for Pelloni developing the game using open source software development tools and Nintendo's refusal to license him the official SDK as well as Bob's response to that decision.
