The Valeriepieris circle is a South China Sea-centered circular region on the world map that is about 4,000 kilometers (2,500 mi) in radius and contains more than half the world’s population. It was named after the Reddit username of Ken Myers, a Texas ESL teacher who first drew attention to the phenomenon in 2013. The map became a meme and was featured in numerous forms of media.

In 2015, the circle was tested by Danny Quah, who verified the claim but moved the circle slightly to exclude most of Japan, and used a globe model rather than a map projection as well as more specific calculations. He calculated that, as of 2015, half of the world's population lived within a 3,300-kilometer (2,050 mi) radius of the city of Mong Khet in Myanmar.

The most common visual of the circle, originally used by Myers and also featured by io9 and Tech in Asia, used the Winkel tripel projection.

Laika (Russian: Лайка; c. 1954 – 3 November 1957) was a Soviet space dog who was one of the first animals in space and the first to orbit the Earth. A stray mongrel from the streets of Moscow, she flew aboard the Sputnik 2 spacecraft, launched into low orbit on 3 November 1957. As the technology to de-orbit had not yet been developed, Laika's survival was never expected. She died of overheating hours into the flight, on the craft's fourth orbit.

Little was known about the impact of spaceflight on living creatures at the time of Laika's mission, and animal flights were viewed by engineers as a necessary precursor to human missions. The experiment, which monitored Laika's vital signs, aimed to prove that a living organism could survive being launched into orbit and continue to function under conditions of weakened gravity and increased radiation, providing scientists with some of the first data on the biological effects of spaceflight.

Laika died within hours from overheating, possibly caused by a failure of the central R‑7 sustainer to separate from the payload. The true cause and time of her death were not made public until 2002; instead, it was widely reported that she died when her oxygen ran out on day six or, as the Soviet government initially claimed, she was euthanised prior to oxygen depletion. In 2008, a small monument to Laika depicting her standing atop a rocket was unveiled near the military research facility in Moscow that prepared her flight. She also appears on the Monument to the Conquerors of Space in Moscow.

🔗 Computing 🔗 Systems

Tab-separated values (TSV) is a simple, text-based file format for storing tabular data. Records are separated by newlines, and values within a record are separated by tab characters. The TSV format is thus a delimiter-separated values format, similar to comma-separated values.

TSV is a simple file format that is widely supported, so it is often used in data exchange to move tabular data between different computer programs that support the format. For example, a TSV file might be used to transfer information from a database to a spreadsheet.

The Strategikon or Strategicon (Greek: Στρατηγικόν) is a manual of war traditionally regarded as written in the late 6th century and usually attributed to the Byzantine Emperor Maurice. It is moreover a practical manual, "a rather modest elementary handbook" in the words of its introduction, "for those devoting themselves to generalship". This book gives a general guide, handbook, of the Byzantine military's strategies. In his introduction to his 1984 translation of the text, George T. Dennis noted "The Strategikon is written in a very straightforward and generally uncomplicated Greek."

The Strategikon may have been written in an effort to codify the military reforms brought about by the soldier-emperor Maurice. There is debate in academic circles as to the true author of the Strategikon. Maurice may have only commissioned it; perhaps his brother Peter, or another general of his court, was the true author. The dating is also debated. If it was written in the 6th century, the Strategikon may have been produced to codify the experience of the Balkan and Persian campaigns, or the campaigns may have been carried out in compliance with the manual. However, starting in the late 19th century, some historians have argued for a later date in the eighth or ninth century, on philological or technological grounds. In any case, it is considered one of the most important military texts of the medieval years, along with the 10th century military treatises attributed to the Byzantine emperors Leo VI (Tactica) and Nicephorus Phocas (De velitatione and Praecepta Militaria); Leo's Tactica in particular drew heavily from the Strategikon.

The text consists of 12 chapters, or "books", on various aspects of the tactics employed by the Byzantine military of the 6th and 7th century A.D. It is primarily focused on cavalry tactics and formations, yet it also elaborates on matters of infantry, sieges, baggage trains, drilling and marching. The author was familiar with classical military treatises, especially Onasander and Aelian, which he used as conceptional models rather than sources of content. Each book has a general topic to be discussed, and each book goes into great detail even separating each book further into subsections and including maps. These maps are not large and extravagant but more symbols to show positions and a standard design of the formations the Byzantine military used at this time. Books seven and eight contain practical advice to the General in the form of instructions and maxims. The eleventh book has ethnographic interest, with its portrayal of various Byzantine enemies (Franks, Lombards, Avars, Turks, and Slavs). The Strategikon also belongs to Byzantine legal literature, since it contains a list of military infractions and their suitable penalties.

🔗 Climate change 🔗 Environment 🔗 Science

There is a nearly unanimous scientific consensus that the Earth has been consistently warming since the start of the Industrial Revolution, that the rate of recent warming is largely unprecedented,^{: 8 : 11} and that this warming is mainly the result of a rapid increase in atmospheric carbon dioxide (CO₂) caused by human activities. The human activities causing this warming include fossil fuel combustion, cement production, and land use changes such as deforestation,^: 10–11 with a significant supporting role from the other greenhouse gases such as methane and nitrous oxide.^: 7 This human role in climate change is considered "unequivocal" and "incontrovertible".^{: 4 : 4}

Nearly all actively publishing climate scientists say humans are causing climate change. Surveys of the scientific literature are another way to measure scientific consensus. A 2019 review of scientific papers found the consensus on the cause of climate change to be at 100%, and a 2021 study concluded that over 99% of scientific papers agree on the human cause of climate change. The small percentage of papers that disagreed with the consensus often contain errors or cannot be replicated.

The evidence for global warming due to human influence has been recognized by the national science academies of all the major industrialized countries. In the scientific literature, there is a very strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases. No scientific body of national or international standing disagrees with this view. A few organizations with members in extractive industries hold non-committal positions, and some have tried to persuade the public that climate change is not happening, or if the climate is changing it is not because of human influence, attempting to sow doubt in the scientific consensus.

🔗 Law

In contract law, a non-compete clause (often NCC), or covenant not to compete (CNC), is a clause under which one party (usually an employee) agrees not to enter into or start a similar profession or trade in competition against another party (usually the employer). Some courts refer to these as "restrictive covenants". As a contract provision, a CNC is bound by traditional contract requirements including the consideration doctrine.

The use of such clauses is premised on the possibility that upon their termination or resignation, an employee might begin working for a competitor or start a business, and gain competitive advantage by exploiting confidential information about their former employer's operations or trade secrets, or sensitive information such as customer/client lists, business practices, upcoming products, and marketing plans.

However, an over-broad CNC may prevent an employee from working elsewhere at all. English common law originally held any such constraint to be unenforceable under the public policy doctrine. Contemporary case law permits exceptions, but generally will only enforce CNCs to the extent necessary to protect the employer. Most jurisdictions in which such contracts have been examined by the courts have deemed CNCs to be legally binding so long as the clause contains reasonable limitations as to the geographical area and time period in which an employee of a company may not compete.

The extent to which non-compete clauses are legally allowed varies per jurisdiction. For example, the state of California in the United States invalidates non-compete-clauses for all but equity stakeholders in the sale of business interests.

In a jury trial, a Chewbacca defense is a legal strategy in which a criminal defense lawyer tries to confuse the jury rather than refute the case of the prosecutor. It is an intentional distraction or obfuscation.

As a Chewbacca defense distracts and misleads, it is an example of a red herring. It is also an example of an irrelevant conclusion, a type of informal fallacy in which one making an argument fails to address the issue in question. Often an opposing counsel can legally object to such arguments by declaring them irrelevant, character evidence, or argumentative.

The name Chewbacca defense comes from "Chef Aid", an episode of the American animated series South Park. The episode, which premiered on October 7, 1998, satirizes the O. J. Simpson murder trial—particularly attorney Johnnie Cochran's closing argument for the defense. In the episode, Cochran (voiced by Trey Parker) bases his argument on a false premise about the 1983 film Return of the Jedi. He asks the jury why a Wookiee like Chewbacca would want to live on Endor with the much smaller Ewoks when "it does not make sense". He argues that if Chewbacca living on Endor does not make sense—and if even mentioning Chewbacca in the case does not make sense—then the jury must acquit.

In the Simpson murder trial, the real Johnnie Cochran tried to convince jurors that a glove found at the crime scene, alleged to have been left by the killer, could not be Simpson's because it did not fit Simpson's hand. Because the prosecution relied on the glove as evidence of Simpson's presence at the scene, Cochran argued that the lack of fit proved Simpson's innocence: "It makes no sense; it doesn't fit; if it doesn't fit, you must acquit." "If it doesn't fit, you must acquit" was a refrain that Cochran also used in response to other points of the case.

🔗 Economics

An Information cascade or informational cascade is a phenomenon described in behavioral economics and network theory in which a number of people make the same decision in a sequential fashion. It is similar to, but distinct from herd behavior.

An information cascade is generally accepted as a two-step process. For a cascade to begin an individual must encounter a scenario with a decision, typically a binary one. Second, outside factors can influence this decision (typically, through the observation of actions and their outcomes of other individuals in similar scenarios).

The two-step process of an informational cascade can be broken down into five basic components:

1. There is a decision to be made – for example; whether to adopt a new technology, wear a new style of clothing, eat in a new restaurant, or support a particular political position

2. A limited action space exists (e.g. an adopt/reject decision)

3. People make the decision sequentially, and each person can observe the choices made by those who acted earlier

4. Each person has some information aside from their own that helps guide their decision

5. A person can't directly observe the outside information that other people know, but he or she can make inferences about this information from what they do

Social perspectives of cascades, which suggest that agents may act irrationally (e.g., against what they think is optimal) when social pressures are great, exist as complements to the concept of information cascades. More often the problem is that the concept of an information cascade is confused with ideas that do not match the two key conditions of the process, such as social proof, information diffusion, and social influence. Indeed, the term information cascade has even been used to refer to such processes.

Cancer Alley (French: Allée du Cancer) is the regional nickname given to an 85-mile (137 km) stretch of land along the Mississippi River between Baton Rouge and New Orleans, in the River Parishes of Louisiana, which contains over 200 petrochemical plants and refineries. This area accounts for 25% of the petrochemical production in the United States. Environmentalists consider the region a sacrifice zone where rates of cancer caused by air pollution exceed the federal government's own limits of acceptable risk. Others have referred to the same region as "Death Alley".

Community leaders such as Sharon Lavigne have led the charge in protesting the expansion of the petrochemical industry in Cancer Alley, as well as addressing the associated racial and economic disparities.
