In philosophy and mathematics, Newcomb's paradox, also referred to as Newcomb's problem, is a thought experiment involving a game between two players, one of whom is able to be able to predict the future.

Newcomb's paradox was created by William Newcomb of the University of California's Lawrence Livermore Laboratory. However, it was first analyzed in a philosophy paper by Robert Nozick in 1969, and appeared in the March 1973 issue of Scientific American, in Martin Gardner's "Mathematical Games." Today it is a much debated problem in the philosophical branch of decision theory.

Sixel, short for "six pixels", is a bitmap graphics format supported by terminals and printers from DEC. It consists of a pattern six pixels high and one wide, resulting in 64 possible patterns. Each possible pattern is assigned an ASCII character, making the sixels easy to transmit on 7-bit serial links.

Sixel was first introduced as a way of sending bitmap graphics to DEC dot matrix printers like the LA50. After being put into "sixel mode" the following data was interpreted to directly control six of the pins in the nine-pin print head. A string of sixel characters encodes a single 6-pixel high row of the image.

The system was later re-used as a way to send bitmap data to the VT200 series and VT320 terminals when defining custom character sets. A series of sixels are used to transfer the bitmap for each character. This feature is known as soft character sets or dynamically redefinable character sets (DRCS). With the VT240, VT241, VT330, and VT340, the terminals could decode a complete sixel image to the screen, like those previously sent to printers.

Wife acceptance factor, wife approval factor, or wife appeal factor (WAF) is an assessment of design elements that either increase or diminish the likelihood a wife will approve the purchase of expensive consumer electronics products such as high-fidelity loudspeakers, home theater systems and personal computers. Stylish, compact forms and appealing colors are commonly considered to have a high WAF. The term is a tongue-in-cheek play on electronics jargon such as "form factor" and "power factor" and derives from the idea that men are predisposed to appreciate gadgetry and performance criteria whereas women must be wooed by visual and aesthetic factors.

On 19 July 2024, a faulty update to security software produced by CrowdStrike, an American cybersecurity company, caused innumerable computers and virtual machines running Microsoft Windows to crash. Businesses and governments around the globe were affected by what one expert called the "largest IT outage in history".

Among the industries that were disrupted were airlines, airports, banks, hotels, hospitals, stock markets, and broadcasting; governmental services such as emergency numbers and websites were also affected. The error was discovered and a fix was made on the same day, but the outage continued to delay airline flights, cause problems in processing electronic payments, and disrupt emergency services.

James Ephraim Lovelock (26 July 1919 – 26 July 2022) was a British independent scientist, environmentalist and futurist. He was best known for proposing the Gaia hypothesis, which postulates that the Earth functions as a self-regulating system.

With a PhD in medicine, Lovelock began his career performing cryopreservation experiments on rodents, including successfully thawing frozen specimens. His methods were influential in the theories of cryonics (the cryopreservation of humans). He invented the electron capture detector, and using it, became the first to detect the widespread presence of chlorofluorocarbons in the atmosphere. While designing scientific instruments for NASA, he developed the Gaia hypothesis.

In the 2000s, he proposed a method of climate engineering to restore carbon dioxide–consuming algae. He was an outspoken member of Environmentalists for Nuclear, asserting that fossil fuel interests have been behind opposition to nuclear energy, citing the effects of carbon dioxide as being harmful to the environment, and warning of global warming due to the greenhouse effect. He authored several environmental science books based upon the Gaia hypothesis from the late 1970s.

A magic eye tube or tuning indicator, in technical literature called an electron-ray indicator tube, is a vacuum tube which gives a visual indication of the amplitude of an electronic signal, such as an audio output, radio-frequency signal strength, or other functions. The magic eye (also called a cat's eye, or tuning eye in North America) is a specific type of such a tube with a circular display similar to the EM34 illustrated. Its first broad application was as a tuning indicator in radio receivers, to give an indication of the relative strength of the received radio signal, to show when a radio station was properly tuned in.

The magic eye tube was the first in a line of development of cathode ray type tuning indicators developed as a cheaper alternative to the needle movement meters. It was not until the 1960s that needle meters were made economically enough in Japan to displace indicator tubes. Tuning indicator tubes were used in vacuum tube receivers from around 1936 to 1980 before vacuum tubes were replaced by transistors in radios. An earlier tuning aid which the magic eye replaced was the "tuneon" neon lamp.

🔗 Musical Instruments

The Siemens Synthesizer (or "Siemens Studio für Elektronische Musik") was developed in Germany in 1959 by the German electronics manufacturer Siemens, originally to compose live electronic music for its own promotional films.

From 1956 to 1967, it had a significant influence on the development of electronic music. Among others, Mauricio Kagel, Henri Pousseur, Herbert Brün and Ernst Krenek completed important electronic works there.

The Sámi National Day is an ethnic national day for the Sámi (Saami) people that falls on February 6, the date when the first Sámi congress was held in 1917 in Trondheim, Norway. The congress was the first time that Norwegian and Swedish Sámi came together across national borders to work on finding solutions to common problems.

In 1992 at the 15th Sámi Conference in Helsinki, Finland, a resolution was passed that Sámi National Day should be celebrated on February 6 to commemorate the first Sámi congress in 1917, that Sami National Day is for all Sámi, regardless of where they live, and on that day the Sámi flag should be flown and the Sámi anthem sung in the local Sámi language. The first time Sami National Day was celebrated was in 1993, when the International Year of Indigenous People was proclaimed open in Jokkmokk, Sweden by the United Nations.

Since then, celebrating the day has become increasingly popular. In Norway, it is compulsory for municipal administrative buildings to fly the Norwegian flag, and optionally also the Sami flag, on February 6. Particularly notable is the celebration in Norway's capital Oslo, where the bells in the highest tower of Oslo City Hall play the Sami national anthem as the flags are raised. Some larger places have taken to arranging festivities in the week around the Sami National Day. The National Day has been included in the almanacs published by the University of Helsinki since 2004. The Norwegian, Swedish, and Finnish authorities recommend general flagging on the day.

By coincidence, February 6 was also the date representatives of the Sámi of the Kola Peninsula gathered annually to meet with Russian bureaucrats to debate and decide on issues of relevance to them. This assembly, called the Kola Sobbar, has been dubbed the "first Sámi Parliament" by the researcher Johan Albert Kalstad. However, the founding of the Kola Sobbar did not influence the choice of the date for Sámi People's Day, as the assembly existed only during the late 1800s and was largely forgotten until the early 2000s.

🔗 Video games

Far Cry is a 2004 first-person shooter game developed by Crytek and published by Ubisoft. It is the first installment in the Far Cry franchise. Set on a mysterious tropical archipelago, the game follows Jack Carver, a former American special operations forces operative, as he searches for journalist Valerie Constantine, who accompanied him to the islands but went missing after their boat was destroyed by mercenaries. As Jack explores the islands, he begins to discover the horrific genetic experiments being conducted on the local wildlife and must confront the mad scientist behind them.

The game was the first to use Crytek's CryEngine, and was designed as an open-ended first-person shooter, though it lacks most of the freedom its successors would offer to the player. While players can freely explore the game's world like in later Far Cry titles, they are most often discouraged from doing so due to the linear structure of missions and the lack of side content. Despite this, the gameplay formula established in Far Cry—placing the player in a foreign environment occupied by enemy forces where they must use various weapons and tools, as well as their surroundings to overcome any threat—would prove essential in defining the series' identity going forward.

Far Cry was released for Microsoft Windows in March 2004 to generally positive reviews, being praised for its visuals, gameplay mechanics, and the level of freedom given to players. The game was also a commercial success, selling over 730,000 units within four months of release and over 2.5 million units in its lifetime. The success of Far Cry led to a series of standalone sequels developed by Ubisoft, starting with Far Cry 2 in 2008. A remake of the game with a different storyline and new mechanics, Far Cry Instincts, was released for the Xbox in 2005, and for the Xbox 360 in 2006 as part of the Far Cry Instincts: Predator compilation. A loose film adaptation was released in 2008. The original version of Far Cry, updated with HD graphics, was re-released under the title Far Cry Classic for the PlayStation 3 and Xbox 360 in 2014.
