The long s (ſ) is an archaic form of the lower case letter s. It replaced the single s, or the first s in a double s (e.g. "ſinfulneſs" for "sinfulness" and "ſucceſs" for "success"). The long s is the basis of the first half of the grapheme or the German alphabet ligature letter ß, which is known as the Eszett. The modern letterform is known as the short, terminal, or round s.

The Tennessee Valley Authority (TVA) is a federally owned electric utility corporation in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. While owned by the federal government, TVA receives no taxpayer funding and operates similarly to a private for-profit company. It is headquartered in Knoxville, Tennessee, and is the sixth-largest power supplier and largest public utility in the country.

The TVA was created by Congress in 1933 as part of President Franklin D. Roosevelt's New Deal. Its initial purpose was to provide navigation, flood control, electricity generation, fertilizer manufacturing, regional planning, and economic development to the Tennessee Valley, a region that had suffered from lack of infrastructure and even more extensive poverty during the Great Depression than other regions of the nation. TVA was envisioned both as a power supplier and a regional economic development agency that would work to help modernize the region's economy and society. It later evolved primarily into an electric utility. It was the first large regional planning agency of the U.S. federal government, and remains the largest.

Under the leadership of David E. Lilienthal, the TVA also became the global model for the United States' later efforts to help modernize agrarian societies in the developing world. The TVA historically has been documented as a success in its efforts to modernize the Tennessee Valley and helping to recruit new employment opportunities to the region. Historians have criticized its use of eminent domain and the displacement of over 125,000 Tennessee Valley residents to build the agency's infrastructure projects.

Timsort is a hybrid stable sorting algorithm, derived from merge sort and insertion sort, designed to perform well on many kinds of real-world data. It was implemented by Tim Peters in 2002 for use in the Python programming language. The algorithm finds subsequences of the data that are already ordered (runs) and uses them to sort the remainder more efficiently. This is done by merging runs until certain criteria are fulfilled. Timsort has been Python's standard sorting algorithm since version 2.3. It is also used to sort arrays of non-primitive type in Java SE 7, on the Android platform, in GNU Octave, on V8, and Swift.

It uses techniques from Peter McIlroy's 1993 paper "Optimistic Sorting and Information Theoretic Complexity".

Guy Fawkes Night, also known as Guy Fawkes Day, Bonfire Night (predominantly Newfoundland) and Firework Night, is an annual commemoration observed on 5 November, primarily in the United Kingdom. Its history begins with the events of 5 November 1605 O.S., when Guy Fawkes, a member of the Gunpowder Plot, was arrested while guarding explosives the plotters had placed beneath the House of Lords. Celebrating the fact that King James I had survived the attempt on his life, people lit bonfires around London; and months later, the introduction of the Observance of 5th November Act enforced an annual public day of thanksgiving for the plot's failure.

Within a few decades Gunpowder Treason Day, as it was known, became the predominant English state commemoration, but as it carried strong Protestant religious overtones it also became a focus for anti-Catholic sentiment. Puritans delivered sermons regarding the perceived dangers of popery, while during increasingly raucous celebrations common folk burnt effigies of popular hate-figures, such as the pope. Towards the end of the 18th century reports appear of children begging for money with effigies of Guy Fawkes and 5 November gradually became known as Guy Fawkes Day. Towns such as Lewes and Guildford were in the 19th century scenes of increasingly violent class-based confrontations, fostering traditions those towns celebrate still, albeit peaceably. In the 1850s changing attitudes resulted in the toning down of much of the day's anti-Catholic rhetoric, and the Observance of 5th November Act was repealed in 1859. Eventually the violence was dealt with, and by the 20th century Guy Fawkes Day had become an enjoyable social commemoration, although lacking much of its original focus. The present-day Guy Fawkes Night is usually celebrated at large organised events, centred on a bonfire and extravagant firework displays.

Settlers exported Guy Fawkes Night to overseas colonies, including some in North America, where it was known as Pope Day. Those festivities died out with the onset of the American Revolution. Claims that Guy Fawkes Night was a Protestant replacement for older customs like Samhain are disputed, although another old celebration, Halloween, has lately increased in popularity in England, and according to some writers, may threaten the continued observance of 5 November.

🔗 Mining 🔗 South Africa

Mponeng is a gold mine in South Africa's Gauteng province. Previously known as Western Deep Levels #1 Shaft, the underground and surface works were commissioned in 1987. It extends over 4 kilometres (2.5 mi) below the surface, and is considered to be one of the most substantial gold mines in the world. It is also currently the world's deepest mine from ground level, reaching a depth of 4 km (2.5 mi) below ground level. The trip from the surface to the bottom of the mine takes over an hour.

Over 5400 metric tonnes of rock are excavated from Mponeng each day. At a price of $19.4 per gram of gold, the mine only needs to extract 10 grams of gold per ton excavated to remain profitable. The mine contains at least two gold reefs, with the deepest one metre thick.

Harmony Gold purchased Mponeng from AngloGold Ashanti in September 2020. Along with AGA's Mine Waste Solutions, Harmony paid approximately $300m.

🔗 Biography 🔗 New York City 🔗 Biography/science and academia 🔗 Anthropology 🔗 Anarchism

David Rolfe Graeber (; February 12, 1961 – September 2, 2020) was an American anthropologist, anarchist activist, and author known for his books Debt: The First 5000 Years (2011), The Utopia of Rules (2015) and Bullshit Jobs: A Theory (2018). He was a professor of anthropology at the London School of Economics.

As an assistant professor and associate professor of anthropology at Yale from 1998 to 2007, Graeber specialized in theories of value and social theory. Yale's decision not to rehire him when he would otherwise have become eligible for tenure sparked an academic controversy. He went on to become, from 2007 to 2013, reader in social anthropology at Goldsmiths, University of London.

His activism includes protests against the 3rd Summit of the Americas in Quebec City in 2001, and at the 2002 World Economic Forum in New York City. Graeber was a leading figure in the Occupy Wall Street movement, and is sometimes credited with having coined the slogan "we are the 99%". He accepted credit for the description "the 99%" but said that others had expanded it into the slogan.

33 Thomas Street (formerly the AT&T Long Lines Building) is a 550-foot-tall (170 m) skyscraper in Civic Center, Lower Manhattan, New York City. It stands on the east side of Church Street, between Thomas Street and Worth Street. The building is an example of the Brutalist architectural style. It is a telephone exchange or wire center building which contained three major 4ESS switches used for interexchange (long distance) telephony, as well as a number of other switches used for competitive local exchange carrier services. However, it is not used for incumbent local exchange carrier services, and is not a central office. The CLLI code for this facility is NYCMNYBW. The building has also been described as the likely location of a National Security Agency (NSA) mass surveillance hub codenamed TITANPOINTE.

TWINKLE (The Weizmann Institute Key Locating Engine) is a hypothetical integer factorization device described in 1999 by Adi Shamir and purported to be capable of factoring 512-bit integers. It is also a pun on the twinkling LEDs used in the device. Shamir estimated that the cost of TWINKLE could be as low as $5000 per unit with bulk production. TWINKLE has a successor named TWIRL which is more efficient.
