🔗 Video games

Doom, a first-person shooter game by id Software, was released in December 1993 and is considered one of the most significant and influential titles in video game history. Development began in November 1992, with programmers John Carmack and John Romero, artists Adrian Carmack and Kevin Cloud, and designer Tom Hall. Late in development, Hall was replaced by Sandy Petersen and programmer Dave Taylor joined. The music and sound effects were created by Bobby Prince.

The Doom concept was proposed in late 1992, after the release of Wolfenstein 3D and its sequel Spear of Destiny. John Carmack was working on an improved 3D game engine from those games, and the team wanted to have their next game take advantage of his designs. Several ideas were proposed, including a new game in their Commander Keen series, but John proposed a game about using technology to fight demons inspired by the Dungeons & Dragons campaigns the team played. The initial months of development were spent building prototypes, while Hall created the Doom Bible, a design document for his vision of the game and its story; after id released a grandiose press release touting features that the team had not yet begun working on, the Doom Bible was rejected in favor of a plotless game with no design document at all.

Over the next six months, Hall designed levels based on real military bases, Romero built features, and artists Adrian and Cloud created textures and demons based on clay models they built. Hall's level designs, however, were deemed uninteresting and Romero began designing his own levels; Hall, increasingly frustrated with his limited influence, was fired in July. He was replaced by Petersen in September, and the team worked increasingly long hours until the game was completed in December 1993. Doom was self-published by id on December 10, 1993, and immediately downloaded by thousands of players.

🔗 India 🔗 Transport 🔗 Travel and Tourism

The bus service from London, England to Calcutta, India (now Kolkata) was considered to be the longest bus route in the world. The bus service, which started in 1957, was routed to India via Belgium, Yugoslavia and North Western India. This route is also known as the Hippie Route. According to reports, it took about 50 days for the bus to reach Calcutta from London. The voyage was over 10,000 miles (16,000 km) one way and 20,300 miles (32,700 km) for the round trip. It was in service until 1976. The cost of the trip one-way was £85 in 1957 and £145 in 1973. This amount included food, travel and accommodation.

🔗 Computing

In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code. An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.

🔗 Philosophy 🔗 Philosophy/Logic 🔗 Philosophy/Ancient philosophy 🔗 Philosophy/Epistemology

"I know that I know nothing" is a saying derived from Plato's account of the Greek philosopher Socrates. Socrates himself was never recorded as having said this phrase, and scholars generally agree that Socrates only ever asserted that he believed that he knew nothing, having never claimed that he knew that he knew nothing. It is also sometimes called the Socratic paradox, although this name is often instead used to refer to other seemingly paradoxical claims made by Socrates in Plato's dialogues (most notably, Socratic intellectualism and the Socratic fallacy).

This saying is also connected or conflated with the answer to a question Socrates (according to Xenophon) or Chaerephon (according to Plato) is said to have posed to the Pythia, the Oracle of Delphi, in which the oracle stated something to the effect of "Socrates is the wisest person in Athens." Socrates, believing the oracle but also completely convinced that he knew nothing, was said to have concluded that nobody knew anything, and that he was only wiser than others because he was the only person who recognized his own ignorance.

🔗 Extinction

Breeding back is a form of artificial selection by the deliberate selective breeding of domestic animals, in an attempt to achieve an animal breed with a phenotype that resembles a wild type ancestor, usually one that has gone extinct. Breeding back is not to be confused with dedomestication.

It must be kept in mind that a breeding-back breed may be very similar to the extinct wild type in phenotype, ecological niche, and to some extent genetics, but the original gene pool of that wild type was eliminated with its extinction. A breeding-back attempt cannot actually recreate the extinct wild type of the breeding target, as an extinct wild type cannot be resurrected through it. Furthermore, even the superficial authenticity of a bred-back animal depends on the quality of the stock used to breed the new lineage. As a result of this, some breeds, like Heck cattle, are at best a vague look-alike of the extinct wild type aurochs, according to the literature.

United States involvement in regime change describes United States government participation or interference, both overt and covert, in the replacement of foreign governments. In the latter half of the 19th century, the U.S. government initiated actions for regime change mainly in Latin America and the southwest Pacific, including the Spanish–American and Philippine–American wars. At the onset of the 20th century, the United States shaped or installed governments in many countries around the world, including neighbors Panama, Honduras, Nicaragua, Mexico, Haiti, and the Dominican Republic.

During World War II, the United States helped overthrow many Nazi Germany or imperial Japanese puppet regimes. Examples include regimes in the Philippines, Korea, the Eastern portion of China, and much of Europe. United States forces were also instrumental in ending the rule of Adolf Hitler over Germany and of Benito Mussolini over Italy. After World War II, the United States in 1945 ratified the UN Charter, the preeminent international law document, which legally bound the U.S. government to the Charter's provisions, including Article 2(4), which prohibits the threat or use of force in international relations, except in very limited circumstances. Therefore, any legal claim advanced to justify regime change by a foreign power carries a particularly heavy burden.

In the aftermath of World War II, the U.S. government struggled with the Soviet Union for global leadership, influence and security within the context of the Cold War. Under the Eisenhower administration, the U.S. government feared that national security would be compromised by governments propped by the Soviet Union's own involvement in regime change and promoted the domino theory, with later presidents following Eisenhower's precedent. Subsequently, the United States expanded the geographic scope of its actions beyond traditional area of operations, Central America and the Caribbean. Significant operations included the United States and United Kingdom-orchestrated 1953 Iranian coup d'état, the 1961 Bay of Pigs Invasion targeting Cuba, and support for the overthrow of Sukarno by General Suharto in Indonesia. In addition, the U.S. has interfered in the national elections of countries, including the Philippines in 1953, and Japan in the 1950s and 1960s as well as Lebanon in 1957. According to one study, the U.S. performed at least 81 overt and covert known interventions in foreign elections during the period 1946–2000. Another study found that the U.S. engaged in 64 covert and six overt attempts at regime change during the Cold War.

Following the dissolution of the Soviet Union, the United States has led or supported wars to determine the governance of a number of countries. Stated U.S. aims in these conflicts have included fighting the War on Terror, as in the ongoing Afghan war, or removing dictatorial and hostile regimes, as in the Iraq War.

🔗 Musical Instruments 🔗 Percussion

Campanology () is the scientific and musical study of bells. It encompasses the technology of bells – how they are founded, tuned and rung – as well as the history, methods, and traditions of bellringing as an art.

It is common to collect together a set of tuned bells and treat the whole as one musical instrument. Such collections – such as a Flemish carillon, a Russian zvon, or an English "ring of bells" used for change ringing – have their own practices and challenges; and campanology is likewise the study of perfecting such instruments and composing and performing music for them.

In this sense, however, the word campanology is most often used in reference to relatively large bells, often hung in a tower. It is not usually applied to assemblages of smaller bells, such as a glockenspiel, a collection of tubular bells, or an Indonesian gamelan.
