π Chomski virtual machine
pattern parsing virtual machine (previously called 'chomski' after Noam Chomsky) and pp (the pattern parser, also a provisional name) refer to both a command line computer language and utility (interpreter for that language) which can be used to parse and transform text patterns and (formal mathematical) languages. The utility reads input files character by character (sequentially), applying the operation which has been specified via the command line or a pp script, and then outputs the line. It was developed from 2006 in the C language. Pp has derived a number of ideas and syntax elements from Sed, a command line text stream editor.

π Benjamin Franklin's 13 virtues
Benjamin Franklin (January 17, 1706 [O.S. January 6, 1705]Β β April 17, 1790) was an American polymath and one of the Founding Fathers of the United States. Franklin was a leading writer, printer, political philosopher, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia's first fire department and the University of Pennsylvania.
Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States Ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In a Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."
Franklin became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies, publishing the Pennsylvania Gazette at the age of 23. He became wealthy publishing this and Poor Richard's Almanack, which he authored under the pseudonym "Richard Saunders". After 1767, he was associated with the Pennsylvania Chronicle, a newspaper that was known for its revolutionary sentiments and criticisms of British policies.
He pioneered and was the first president of Academy and College of Philadelphia which opened in 1751 and later became the University of Pennsylvania. He organized and was the first secretary of the American Philosophical Society and was elected president in 1769. Franklin became a national hero in America as an agent for several colonies when he spearheaded an effort in London to have the Parliament of Great Britain repeal the unpopular Stamp Act. An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco-American relations. His efforts proved vital for the American Revolution in securing shipments of crucial munitions from France.
He was promoted to deputy postmaster-general for the British colonies in 1753, having been Philadelphia postmaster for many years, and this enabled him to set up the first national communications network. During the revolution, he became the first United States Postmaster General. He was active in community affairs and colonial and state politics, as well as national and international affairs. From 1785 to 1788, he served as governor of Pennsylvania. He initially owned and dealt in slaves but, by the late 1750s, he began arguing against slavery and became an abolitionist.
His life and legacy of scientific and political achievement, and his status as one of America's most influential Founding Fathers, have seen Franklin honored more than two centuries after his death on coinage and the $100 bill, warships, and the names of many towns, counties, educational institutions, and corporations, as well as countless cultural references.

π The Covox Speech Thing
The Covox Speech Thing is an external audio device attached to the computer to output digital sound. It was composed of a primitive 8-bit DAC using a resistor ladder and an analogue signal output, and plugged into the printer port of the PC.
The Speech Thing was introduced on December 18, 1987 by Covox, Inc of Eugene, Oregon, for about US$70 (US$79.95 as of 1989), but as its parts were much cheaper than the complete plug, and as its design was fairly simple, people soon started to build their own variants. The plug was used long into the 1990s, as sound cards were still very expensive at that time. The plug was also quite popular in the demoscene.
An inherent problem of the design is that it requires very precise resistors. If normal parts are used, the values get shuffled, especially for quiet sounds, resulting in distortion. Nevertheless, the sound quality of the Covox plug is far superior compared to the PC speaker; even today, a self-built Covox plug is still an inexpensive way to give old computers sound capabilities.

π James-Lange Theory
The JamesβLange theory is a hypothesis on the origin and nature of emotions and is one of the earliest theories of emotion within modern psychology. It was developed by philosopher John Dewey and named for two 19th-century scholars, William James and Carl Lange (see modern criticism for more on the theory's origin). The basic premise of the theory is that physiological arousal instigates the experience of emotion. Previously people considered emotions as reactions to some significant events or their features, i.e. events come first, and then there is an emotional response. James-Lange theory proposed that the state of the body can induce emotions or emotional dispositions. In other words, this theory suggests that when we feel teary, it generates a disposition for sad emotions; when our heartbeat is out of normality, it makes us feel anxiety. Instead of feeling an emotion and subsequent physiological (bodily) response, the theory proposes that the physiological change is primary, and emotion is then experienced when the brain reacts to the information received via the body's nervous system. It proposes that each specific category of emotion is attached to a unique and different pattern of physiological arousal and emotional behaviour in reaction due to an exciting stimulus.
The theory has been criticized and modified over the course of time, as one of several competing theories of emotion. Modern theorists have built on its ideas by proposing that the experience of emotion is modulated by both physiological feedback and other information, rather than consisting solely of bodily changes, as James suggested. Psychologist Tim Dalgleish states that most modern affective neuroscientists would support such a viewpoint. In 2002, a research paper on the autonomic nervous system stated that the theory has been "hard to disprove".

π Ever Dream This Man?
This Man, according to a website created in 2008 by Italian marketer Andrea Natella named Ever Dream This Man?, was a person who was claimed to have been repeatedly seen in dreams by the whole world since 2006, but was never found in the real world. Natella created the site in 2008, but it was not until October 2009 that it gained attention from the press and online internet users. This Man's notoriety spawned several internet memes that spoofed flyers of the website, references in films and television shows like The X-Files, and a manga series based on the hoax by Weekly Shonen Magazine.

π Scientific Consensus on Climate Change
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,:β8β:β11β 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,:β10β11β with a significant supporting role from the other greenhouse gases such as methane and nitrous oxide.:β7β This human role in climate change is considered "unequivocal" and "incontrovertible".:β4β:β4β
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.
π Pumpable Ice Technology
Pumpable ice (PI) technology is a technology to produce and use fluids or secondary refrigerants, also called coolants, with the viscosity of water or jelly and the cooling capacity of ice. Pumpable ice is typically a slurry of ice crystals or particles ranging from 5 micrometers to 1 cm in diameter and transported in brine, seawater, food liquid, or gas bubbles of air, ozone, or carbon dioxide.

π Pyrotherapy
Pyrotherapy (artificial fever) is a method of treatment by raising the body temperature or sustaining an elevated body temperature using a fever. In general, the body temperature was maintained at 41Β Β°C (105Β Β°F). Many diseases were treated by this method in the first half of the 20th century. In general, it was done by exposing the patient to hot baths, warm air, or (electric) blankets. The technique reached its peak of sophistication in the early 20th century with malariotherapy, in which Plasmodium vivax, a causative agent of malaria, was allowed to infect already ill patients in order to produce intense fever for therapeutic ends. The sophistication of this approach lay in using effective anti-malarial drugs to control the P. vivax infection, while maintaining the fever it causes to the detriment of other, ongoing, and then-incurable infections present in the patient, such as late-stage syphilis. This type of pyrotherapy was most famously used by psychiatrist Julius Wagner-Jauregg, who won the Nobel Prize for Medicine in 1927 for his elaboration of the procedure in treating neurosyphilitics.

π The Indian state of Kerala has a communist government and India's highest HDI
Communism in Kerala refers to the strong presence of communist ideas in the Indian state of Kerala. In addition to Kerala, the Indian states of West Bengal and Tripura have had multiple democratically elected Marxist governments, and change takes place in the government by regular multiparty electoral processes. Communism of Kerala has provided Indian communist stalwarts such as M. N. Govindan Nair, C. Achutha Menon, K. Damodaran, T. V. Thomas, N. E. Balaram, E. M. S. Namboodiripad, A. K. Gopalan, K. R. Gouri Amma, P. K. Vasudevan Nair and C. K. Chandrappan
Today the two largest communist parties in Kerala politics are the Communist Party of India (Marxist) and the Communist Party of India. The Left Democratic Front is a coalition of left-wing political parties in the state of Kerala and is one of the two major political coalitions in Kerala, each of which have been in power alternatively for the last two decades. The coalition led by the Communist Party of India (Marxist) consists of the Communist Party of India, the Janata Dal (Secular), the Nationalist Congress Party, the Indian National League, the Kerala Congress (Anti-merger Group), and the Indian National Congress (Socialist).
