In computer programming, COMEFROM (or COME FROM) is an obscure control flow structure used in some programming languages, originally as a joke. COMEFROM is roughly the opposite of GOTO in that it can take the execution state from any arbitrary point in code to a COMEFROM statement.

The point in code where the state transfer happens is usually given as a parameter to COMEFROM. Whether the transfer happens before or after the instruction at the specified transfer point depends on the language used. Depending on the language used, multiple COMEFROMs referencing the same departure point may be invalid, be non-deterministic, be executed in some sort of defined priority, or even induce parallel or otherwise concurrent execution as seen in Threaded Intercal.

A simple example of a "COMEFROM x" statement is a label x (which does not need to be physically located anywhere near its corresponding COMEFROM) that acts as a "trap door". When code execution reaches the label, control gets passed to the statement following the COMEFROM. This may also be conditional, passing control only if a condition is satisfied, analogous to a GOTO within an IF statement. The primary difference from GOTO is that GOTO only depends on the local structure of the code, while COMEFROM depends on the global structure – a GOTO transfers control when it reaches a line with a GOTO statement, while COMEFROM requires scanning the entire program or scope to see if any COMEFROM statements are in scope for the line, and then verifying if a condition is hit. The effect of this is primarily to make debugging (and understanding the control flow of the program) extremely difficult, since there is no indication near the line or label in question that control will mysteriously jump to another point of the program – one must study the entire program to see if any COMEFROM statements reference that line or label.

Debugger hooks can be used to implement a COMEFROM statement, as in the humorous Python goto module; see below. This also can be implemented with the gcc feature "asm goto" as used by the Linux kernel configuration option CONFIG_JUMP_LABEL. A no-op has its location stored, to be replaced by a jump to an executable fragment that at its end returns to the instruction after the no-op.

The Kee Bird was a United States Army Air Forces Boeing B-29 Superfortress, serial 45-21768, of the 46th Reconnaissance Squadron, that became marooned after making an emergency landing in northwest Greenland during a secret Cold War spying mission on 21 February 1947. While the entire crew was safely evacuated after spending three days in the isolated Arctic tundra, the aircraft itself was left at the landing site. It lay there undisturbed until 1994, when a privately funded mission was launched to repair and return it. During the attempted recovery, a fire broke out, resulting in the destruction and loss of the airframe on the ground.

The Code of Hammurabi is a well-preserved Babylonian code of law of ancient Mesopotamia, dated to about 1754 BC (Middle Chronology). It is one of the oldest deciphered writings of significant length in the world. The sixth Babylonian king, Hammurabi, enacted the code. A partial copy exists on a 2.25-metre-tall (7.5 ft) stone stele. It consists of 282 laws, with scaled punishments, adjusting "an eye for an eye, a tooth for a tooth" (lex talionis) as graded based on social stratification depending on social status and gender, of slave versus free, man versus woman.

Nearly half of the code deals with matters of contract, establishing the wages to be paid to an ox driver or a surgeon for example. Other provisions set the terms of a transaction, the liability of a builder for a house that collapses, or property that is damaged while left in the care of another. A third of the code addresses issues concerning household and family relationships such as inheritance, divorce, paternity, and reproductive behavior. Only one provision appears to impose obligations on a government official; this provision establishes that a judge who alters his decision after it is written down is to be fined and removed from the bench permanently. A few provisions address issues related to military service.

The code was discovered by modern archaeologists in 1901, and its editio princeps translation published in 1902 by Jean-Vincent Scheil. This nearly complete example of the code is carved into a diorite stele in the shape of a huge index finger, 2.25 m (7.4 ft) tall. The code is inscribed in the Akkadian language, using cuneiform script carved into the stele. The material was imported into Sumeria from Magan - today the area covered by the United Arab Emirates and Oman.

It is currently on display in the Louvre, with replicas in numerous institutions, including the Oriental Institute at the University of Chicago, the Northwestern Pritzker School of Law in Chicago, the Clendening History of Medicine Library & Museum at the University of Kansas Medical Center, the library of the Theological University of the Reformed Churches in the Netherlands, the Pergamon Museum of Berlin, the Arts Faculty of the University of Leuven in Belgium, the National Museum of Iran in Tehran, the Department of Anthropology, National Museum of Natural History, Smithsonian Institution, the University Museum at the University of Pennsylvania, the Pushkin State Museum of Fine Arts in Russia, the Prewitt-Allen Archaeological Museum at Corban University, Garrett-Evangelical Theological Seminary, and Museum of the Bible in Washington, DC.

Taarof or Tarof (also transliterated as Taʿârof; Persian: تعارف‎) is a Persian word which refers to an Iranian form of civility or art of etiquette that emphasizes both deference and social rank.

Etymologically the origins of the word trace back to an Arabic word meaning "acquaintance" or "knowledge", but Iranians have transformed taarof into something "uniquely Iranian" and tend to understand it as a ritual politeness that levels the playing field and promotes equality in a hierarchical culture. Taarof between friends, or a host and guest, emphasizes the value of friendship as a priority to everything else in the world. Another understanding is that taarof is a way of managing social relations with decorous manners. It could be used as a basis for mutual goodwill (positively) or as "a social or political weapon that confuses the recipient and puts him at a disadvantage" (negatively). Those who are intimately familiar with Iranian culture seem to agree that taarof is one of the most fundamental things to understand about Iranian culture.

According to Middle East scholar William O. Beeman, "Taarof is an extraordinarily difficult concept encompassing a broad complex of behaviors which mark and underscore differences in social status." For example, in Iranian culture, whoever walks through a doorway first gets a form of status, but the person who makes the other go through the door first also gains status by having made the other person do it through their show of grace and deference. When it comes to matters of rank, "one defers to superiors (tribute), and confers on inferiors (favor), presses honor on equals (neither tribute nor favor) or accepts the honor from a proper source, and thereby "wins". Status is relative for individuals in different interactions, according to Beeman, and rights and obligations shift constantly with changes in social environments.

Carcinisation (or carcinization) is an example of convergent evolution in which a crustacean evolves into a crab-like form from a non-crab-like form. The term was introduced into evolutionary biology by L. A. Borradaile, who described it as "one of the many attempts of Nature to evolve a crab".

British Airways Flight 9, sometimes referred to by its callsign Speedbird 9 or as the Jakarta incident, was a scheduled British Airways flight from London Heathrow to Auckland, with stops in Bombay, Kuala Lumpur, Perth, and Melbourne.

On 24 June 1982, the route was flown by the City of Edinburgh, a Boeing 747-200. The aircraft flew into a cloud of volcanic ash thrown up by the eruption of Mount Galunggung (approximately 110 miles (180 km) south-east of Jakarta, Indonesia), resulting in the failure of all four engines. The reason for the failure was not immediately apparent to the crew or air traffic control. The aircraft was diverted to Jakarta in the hope that enough engines could be restarted to allow it to land there. The aircraft glided out of the ash cloud, and all engines were restarted (although one failed again soon after), allowing the aircraft to land safely at the Halim Perdanakusuma Airport in Jakarta.

The crew members of the accident segment had boarded the aircraft in Kuala Lumpur, while many of the passengers had been aboard since the flight began in London.

The Hokkaido characters (北海道異体文字, hokkaidō itai moji), also known as Aino characters (アイノモジ, aino moji) or Ainu characters (アイヌ文字, ainu moji), are a set of characters discovered around 1886 on the Japanese island of Hokkaido. At the time of their discovery, they were believed to be a genuine script, but this view is not generally supported today.
