319 Leona (provisional designation A920 HE), is a dark asteroid and tumbling slow rotator from the outermost regions of the asteroid belt, approximately 70 kilometers in diameter. It was discovered on 8 October 1891, by French astronomer Auguste Charlois at Nice Observatory in southwestern France. Any reference of its name to a person is unknown. On 12 December 2023 Leona will occult Betelgeuse as seen from southern Europe.

Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "JavaScript everywhere" paradigm, unifying web-application development around a single programming language, rather than different languages for server- and client-side scripts.

Though .js is the standard filename extension for JavaScript code, the name "Node.js" doesn't refer to a particular file in this context and is merely the name of the product. Node.js has an event-driven architecture capable of asynchronous I/O. These design choices aim to optimize throughput and scalability in web applications with many input/output operations, as well as for real-time Web applications (e.g., real-time communication programs and browser games).

The Node.js distributed development project was previously governed by the Node.js Foundation, and has now merged with the JS Foundation to form the OpenJS Foundation, which is facilitated by the Linux Foundation's Collaborative Projects program.

Corporate users of Node.js software include GoDaddy, Groupon, IBM, LinkedIn, Microsoft, Netflix, PayPal, Rakuten, SAP, Voxer, Walmart, and Yahoo!.

In social psychology, fundamental attribution error (FAE), also known as correspondence bias or attribution effect, is the tendency for people to under-emphasize situational explanations for an individual's observed behavior while over-emphasizing dispositional and personality-based explanations for their behavior. This effect has been described as "the tendency to believe that what people do reflects who they are".

Ronald Lewis Graham (born October 31, 1935) is an American mathematician credited by the American Mathematical Society as being "one of the principal architects of the rapid development worldwide of discrete mathematics in recent years". He has done important work in scheduling theory, computational geometry, Ramsey theory, and quasi-randomness.

He is the Chief Scientist at the California Institute for Telecommunications and Information Technology (also known as Cal-(IT)²) and the Irwin and Joan Jacobs Professor in Computer Science and Engineering at the University of California, San Diego (UCSD).

The Voith Schneider propeller (VSP), also known as a cycloidal drive is a specialized marine propulsion system (MPS). It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries.

Distributism is an economic theory asserting that the world's productive assets should be widely owned rather than concentrated.

Developed in Europe in the late 19th and early 20th centuries, distributism was based upon the principles of Catholic social teaching, especially the teachings of Pope Leo XIII in his encyclical Rerum novarum (1891) and Pope Pius XI in Quadragesimo anno (1931). It views both capitalism and socialism as equally flawed and exploitative, and it favors economic mechanisms such as cooperatives and member-owned mutual organizations as well as small businesses, and large-scale antitrust regulations.

Some Christian democratic political parties have advocated distributism in their economic policies.

Petrodollar recycling is the international spending or investment of a country's revenues from petroleum exports ("petrodollars"). It generally refers to the phenomenon of major petroleum-exporting nations, mainly the OPEC members plus Russia and Norway, earning more money from the export of crude oil than they could efficiently invest in their own economies. The resulting global interdependencies and financial flows, from oil producers back to oil consumers, can reach a scale of hundreds of billions of US dollars per year – including a wide range of transactions in a variety of currencies, some pegged to the US dollar and some not. These flows are heavily influenced by government-level decisions regarding international investment and aid, with important consequences for both global finance and petroleum politics. The phenomenon is most pronounced during periods when the price of oil is historically high.

The term petrodollar was coined in the early 1970s during the oil crisis, and the first major petrodollar surge (1974–1981) resulted in more financial complications than the second (2005–2014).

In August 2018, Venezuela declared that it would price its oil in Euros, Yuan and other currencies.

The Eleanor crosses were a series of twelve tall and lavishly decorated stone monuments topped with crosses erected in a line down part of the east of England. King Edward I had them built between 1291 and about 1295 in memory of his beloved wife Eleanor of Castile. The King and Queen had been married for 36 years and she stayed by the King’s side through his many travels. While on a royal progress, she died in the East Midlands in November 1290, perhaps due to fever. The crosses, erected in her memory, marked the nightly resting-places along the route taken when her body was transported to Westminster Abbey near London.

The crosses stood at Lincoln, Grantham and Stamford, all in Lincolnshire; Geddington and Hardingstone in Northamptonshire; Stony Stratford in Buckinghamshire; Woburn and Dunstable in Bedfordshire; St Albans and Waltham (now Waltham Cross) in Hertfordshire; Cheapside in London; and Charing (now Charing Cross) in Westminster.

Three of the medieval monuments – those at Geddington, Hardingstone and Waltham Cross – survive more or less intact; but the other nine, other than a few fragments, are lost. The largest and most ornate of the twelve was the Charing Cross. Several memorials and elaborated reproductions of the crosses have been erected, including the Queen Eleanor Memorial Cross at Charing Cross Station (built 1865).

Roland the Farter (known in contemporary records as Roland le Fartere, Roulandus le Fartere or Roland le Petour) was a medieval flatulist who lived in twelfth-century England. He was given Hemingstone manor in Suffolk and 12 hectares (30 acres) of land in return for his services as a jester for King Henry II. Each year he was obliged to perform "Unum saltum et siffletum et unum bumbulum" (one jump, one whistle, and one fart) for the King's court at Christmas.

Roland is listed in the thirteenth-century English Liber Feodorum (Book of Fees).

🔗 Computing

In computing, an oops is a deviation from correct behavior of the Linux kernel, one that produces a certain error log. The better-known kernel panic condition results from many kinds of oops, but other instances of an oops event may allow continued operation with compromised reliability. The term does not stand for anything, other than that it is a simple mistake.

When the kernel detects a problem, it kills any offending processes and prints an oops message, which Linux kernel engineers can use in debugging the condition that created the oops and fixing the underlying programming error. After a system has experienced an oops, some internal resources may no longer be operational. Thus, even if the system appears to work correctly, undesirable side effects may have resulted from the active task being killed. A kernel oops often leads to a kernel panic when the system attempts to use resources that have been lost.

The official Linux kernel documentation regarding oops messages resides in the file Documentation/admin-guide/bug-hunting.rst of the kernel sources. Some logger configurations may affect the ability to collect oops messages. The kerneloops software can collect and submit kernel oopses to a repository such as the www.kerneloops.org website, which provides statistics and public access to reported oopses.

For a person not familiar with technical details of computers and operating systems, an oops message might look confusing. Unlike other operating systems such as Windows or macOS, Linux chooses to present details explaining the crash of the kernel rather than display a simplified, user-friendly message, such as the BSoD on Windows. A simplified crash screen has been proposed a few times, however currently none are in development.
