The Council of Trent (Latin: Concilium Tridentinum), held between 1545 and 1563 in Trent (or Trento), now in northern Italy, was the 19th ecumenical council of the Catholic Church. Prompted by the Protestant Reformation at the time, it has been described as the embodiment of the Counter-Reformation.

The Council issued condemnations of what it defined to be heresies committed by proponents of Protestantism, and also issued key statements and clarifications of the Church's doctrine and teachings, including scripture, the biblical canon, sacred tradition, original sin, justification, salvation, the sacraments, the Mass, and the veneration of saints. The Council met for twenty-five sessions between 13 December 1545 and 4 December 1563. Pope Paul III, who convoked the Council, oversaw the first eight sessions (1545–47), while the twelfth to sixteenth sessions (1551–52) were overseen by Pope Julius III and the seventeenth to twenty-fifth sessions (1562–63) by Pope Pius IV.

The consequences of the Council were also significant with regard to the Church's liturgy and practices. In its decrees, the Council made the Latin Vulgate the official biblical text of the Roman Church (without prejudice to the original texts in Hebrew and Greek, nor to other traditional translations of the Church, but favoring the Latin language over vernacular translations, such as the controversial English-language Tyndale Bible). In doing so, they commissioned the creation of a revised and standardized Vulgate in light of textual criticism, although this was not achieved until the 1590s. The Council also officially affirmed (for the second time at an ecumenical council) the traditional Catholic Canon of biblical books in response to the increasing Protestant exclusion of the deuterocanonical books. The former dogmatic affirmation of the Canonical books was at the Council of Florence in the 1441 bull Cantate Domino, as affirmed by Pope Leo XIII in his 1893 encyclical Providentissimus Deus (#20). In 1565, a year after the Council finished its work, Pius IV issued the Tridentine Creed (after Tridentum, Trent's Latin name) and his successor Pius V then issued the Roman Catechism and revisions of the Breviary and Missal in, respectively, 1566, 1568 and 1570. These, in turn, led to the codification of the Tridentine Mass, which remained the Church's primary form of the Mass for the next four hundred years.

More than three hundred years passed until the next ecumenical council, the First Vatican Council, was convened in 1869.

Kopi luwak (Indonesian pronunciation: [ˈkopi ˈlu.aʔ]), also known as civet coffee, is a coffee that consists of partially digested coffee cherries, which have been eaten and defecated by the Asian palm civet (Paradoxurus hermaphroditus). The cherries are fermented as they pass through a civet's intestines, and after being defecated with other fecal matter, they are collected. These civets are increasingly caught in the wild and traded for this purpose.

Kopi luwak is produced mainly on the Indonesian islands of Sumatra, Java, Bali, Sulawesi, and in East Timor. It is also widely gathered in the forest or produced in farms in the islands of the Philippines, where the product is called kape motit in the Cordillera region, kapé alamíd in Tagalog areas, kapé melô or kapé musang in Mindanao, and kahawa kubing in the Sulu Archipelago.

Kopi luwak is also produced in Palawan's Langogan Valley. The beans from droppings of the Asian palm civet and Palawan binturong (Arctictis binturong whitei) are collected from the forest floor and cleaned.

Producers of the coffee beans argue that the process may improve coffee through two mechanisms: selection, where civets choose to eat only certain cherries; and digestion, where biological or chemical mechanisms in the animals' digestive tracts alter the composition of the coffee cherries.

The traditional method of collecting feces from wild Asian palm civets has given way to an intensive farming method, in which the palm civets are kept in battery cages and are force-fed the cherries. This method of production has raised ethical concerns about the treatment of civets and the conditions they are made to live in, which include isolation, poor diet, small cages, and a high mortality rate.

Although kopi luwak is a form of processing rather than a variety of coffee, it has been called one of the most expensive coffees in the world, with retail prices reaching $100 per kilogram ($45/lb) for farmed beans and $1,300 per kilogram ($590/lb) for wild-collected beans. Another epithet for it is the "Holy Grail of coffees".

Al pastor (from Spanish, "shepherd style"), tacos al pastor, or tacos de trompo is a preparation of spit-grilled slices of pork originating in the Central Mexican region of Puebla and Mexico City, although today it is a common menu item found in taquerías throughout Mexico. The method of preparing and cooking al pastor is based on the lamb shawarma brought by Lebanese immigrants to the region. Al pastor features a flavor palate that uses traditional Mexican adobada (marinade). It is a popular street food that has spread to the United States. In some places of northern Mexico and coastal Mexico, such as in Baja California, taco al pastor is known as taco de trompo or taco de adobada. A similar dish also from Puebla that uses a combination of middle eastern spices and indigenous central Mexican ingredients is called tacos árabes.

🔗 Trains

In rail transportation, a rolling highway or rolling road is a form of combined transport involving the conveying of road trucks by rail, referred to as Ro-La trains. The concept is a form of piggyback transportation.

The technical challenges to implement rolling highways vary from region to region. In North America, the loading gauge is often high enough to accommodate double stack containers, so the height of a semi-trailer on a flatcar is no issue. However, in Europe, except for purpose built lines such as the Channel Tunnel or the Gotthard Base Tunnel, the loading gauge height is much smaller, and it is necessary to transport the trailers with the tires about 30 cm (11.81 in) above the rails, so the trailers cannot be simply parked on the surface of a flat car above the wagon wheels or bogies. Making the wagon wheels smaller limits the maximum speed, so many designs allow the trailer to be transported with its wheels lower than the rail wagon wheels. An early approach in France was the Kangourou wagon with modified trailers. This technology did not survive, due to the market resistance to modified trailers. Today, three designs for these special wagons are in commercial service, "Modalohr", "CargoBeamer" and "Niederflurwagen" .

During a rolling-highway journey, if the drivers accompany the trailer, they are accommodated in a passenger car or a sleeping car. At both ends of the rail link there are purpose-built terminals that allow the train to be easily loaded and unloaded.

I Get This Call Every Day is a 2012 point-and-click video game developed and published by Toronto-based developer David S Gallant. It was released for Microsoft Windows and OS X on December 21, 2012. It focuses on a call received by an employee of a customer service call centre; the player must navigate through the call without irritating the caller or breaking confidentiality laws. Gallant was fired from his job at a call centre as a direct result of publishing the game.

Pink noise or ​¹⁄_f noise is a signal or process with a frequency spectrum such that the power spectral density (energy or power per frequency interval) is inversely proportional to the frequency of the signal. In pink noise, each octave (halving or doubling in frequency) carries an equal amount of noise energy.

Pink noise is one of the most common signals in biological systems.

The name arises from the pink appearance of visible light with this power spectrum. This is in contrast with white noise which has equal intensity per frequency interval.

🔗 Urban studies and planning 🔗 Cooperatives 🔗 Israel

A kibbutz (Hebrew: קִבּוּץ‎ / קיבוץ‎, lit. "gathering, clustering"; plural: kibbutzim קִבּוּצִים‎ / קיבוצים‎) is a collective community in Israel that was traditionally based on agriculture. The first kibbutz, established in 1909, was Degania. Today, farming has been partly supplanted by other economic branches, including industrial plants and high-tech enterprises. Kibbutzim began as utopian communities, a combination of socialism and Zionism. In recent decades, some kibbutzim have been privatized and changes have been made in the communal lifestyle. A member of a kibbutz is called a kibbutznik (Hebrew: קִבּוּצְנִיק‎ / קיבוצניק‎; plural kibbutznikim or kibbutzniks).

In 2010, there were 270 kibbutzim in Israel. Their factories and farms account for 9% of Israel's industrial output, worth US$8 billion, and 40% of its agricultural output, worth over $1.7 billion. Some kibbutzim had also developed substantial high-tech and military industries. For example, in 2010, Kibbutz Sasa, containing some 200 members, generated $850 million in annual revenue from its military-plastics industry.

Currently the kibbutzim are organised in the secular Kibbutz Movement with some 230 kibbutzim, the Religious Kibbutz Movement with 16 kibbutzim and the much smaller religious Poalei Agudat Yisrael with two kibbutzim, all part of the wider communal settlement movement.

🔗 Systems 🔗 Systems/Control theory

In control theory, a bang–bang controller (2 step or on–off controller), also known as a hysteresis controller, is a feedback controller that switches abruptly between two states. These controllers may be realized in terms of any element that provides hysteresis. They are often used to control a plant that accepts a binary input, for example a furnace that is either completely on or completely off. Most common residential thermostats are bang–bang controllers. The Heaviside step function in its discrete form is an example of a bang–bang control signal. Due to the discontinuous control signal, systems that include bang–bang controllers are variable structure systems, and bang–bang controllers are thus variable structure controllers.
