The self-referencing doomsday argument rebuttal is an attempt to refute the doomsday argument (that there is a credible link between the brevity of the human race's existence and its expected extinction) by applying the same reasoning to the lifetime of the doomsday argument itself.

The first researchers to write about this were P. T. Landsberg and J. N. Dewynne in 1997; they applied belief in the doomsday argument to itself, and claimed that a paradox results.

The emo killings in Iraq were a string of homicides that were part of a campaign against Iraqi teenage boys who dressed in a Westernized emo style. Between 6 and 70 young men were kidnapped, tortured and murdered in Baghdad and Iraq during March 2012. In September 2012, BBC News reported that gay men in Baghdad said the killings had not abated.

This is a list of etymologies proposed for the word OK or okay. The majority can be easily classified as false etymologies, or possibly folk etymologies. H. L. Mencken, in The American Language, lists serious candidates and "a few of the more picturesque or preposterous". Allen Walker Read surveyed a variety of explanations in a 1964 article titled The Folklore of "O. K." Eric Partridge described O.K. as "an evergreen of the correspondence column."

The San Jose electric light tower, also known as Owen's Electric Tower after its creator and chief booster, was constructed in 1881 at an intersection in downtown San Jose, California, as a "high light" or moonlight tower to light the city using arc lights. A pioneer use of electricity for municipal lighting, it was later strung with incandescent bulbs and was destroyed in a storm in December 1915. A half-size replica stands at History Park at Kelley Park.

The extreme weather events of 535–536 were the most severe and protracted short-term episodes of cooling in the Northern Hemisphere in the last 2,000 years. The event is thought to have been caused by an extensive atmospheric dust veil, possibly resulting from a large volcanic eruption in the tropics or in Iceland. Its effects were widespread, causing unseasonable weather, crop failures, and famines worldwide.

🔗 Germany 🔗 Anthroponymy

Kevinism and Chantalism jokingly describe the tendency of parents in German-speaking areas to name their children with what appears to them to be unusual, exotic-sounding first names.

🔗 Ships 🔗 Egypt

The Yellow Fleet was the name given to a group of fifteen ships trapped in the Suez Canal (in the Great Bitter Lake section) from 1967 to 1975 as a result of the Israel-Egypt Six-Day War. Both ends of the canal had been blocked by the Egyptians with scuttled ships and other obstacles. The name Yellow Fleet derived from their yellow appearance as they were increasingly covered in a desert sand swept on board. After eight years, the only ships that were able to return to their home port under their own power were the West German ships Münsterland and Nordwind.

Van Eck phreaking (also known as Van Eck Radiation) is a form of eavesdropping in which special equipment is used to pick up side-band electromagnetic emissions from electronic devices that correlate to hidden signals or data for the purpose of recreating these signals or data in order to spy on the electronic device. Side-band electromagnetic radiation emissions are present in (and with the proper equipment, can be captured from) keyboards, computer displays, printers, and other electronic devices.

In 1985, Wim van Eck published the first unclassified technical analysis of the security risks of emanations from computer monitors. This paper caused some consternation in the security community, which had previously believed that such monitoring was a highly sophisticated attack available only to governments; van Eck successfully eavesdropped on a real system, at a range of hundreds of metres, using just $15 worth of equipment plus a television set.

As a consequence of this research, such emanations are sometimes called "van Eck radiation", and the eavesdropping technique van Eck phreaking. Government researchers were already aware of the danger, as Bell Labs had noted this vulnerability to secure teleprinter communications during World War II and was able to produce 75% of the plaintext being processed in a secure facility from a distance of 80 feet (24 metres). Additionally the NSA published Tempest Fundamentals, NSA-82-89, NACSIM 5000, National Security Agency (Classified) on February 1, 1982. In addition, the van Eck technique was successfully demonstrated to non-TEMPEST personnel in Korea during the Korean War in the 1950s.

While Phreaking is the process of exploiting telephone networks, it is used here because of its connection to eavesdropping. Van Eck phreaking of CRT displays is the process of eavesdropping on the contents of a CRT by detecting its electromagnetic emissions.

🔗 Public Art 🔗 Textile Arts 🔗 Graffiti

Yarn bombing (or yarnbombing) is a type of graffiti or street art that employs colourful displays of knitted or crocheted yarn or fibre rather than paint or chalk. It is also called wool bombing, yarn storming, guerrilla knitting, kniffiti, urban knitting, or graffiti knitting.
