The Great Pyramid of Cholula, also known as Tlachihualtepetl (Nahuatl for "made-by-hand mountain"), is a complex located in Cholula, Puebla, Mexico. It is the largest archaeological site of a pyramid (temple) in the New World, as well as the largest pyramid by volume known to exist in the world today. The adobe brick pyramid stands 25 metres (82 ft) above the surrounding plain, which is significantly shorter than the Great Pyramid of Giza's height of 146.6 metres (481 ft), but much wider, measuring 300 by 315 metres (984 by 1,033 ft) in its final form, compared to the Great Pyramid's base dimensions of 230.3 by 230.3 metres (756 by 756 ft). The pyramid is a temple that traditionally has been viewed as having been dedicated to the god Quetzalcoatl. The architectural style of the building was linked closely to that of Teotihuacan in the Valley of Mexico, although influence from the Gulf Coast is evident as well, especially from El Tajín.

🔗 United States 🔗 Languages 🔗 United States/Mississippi

"Thank God for Mississippi" is an adage used in the United States, particularly in the South, that is generally used when discussing rankings of U.S. states. Since the U.S. state of Mississippi commonly ranks at or near the bottom of such rankings, residents of other states also ranking near the bottom may say, "Thank God for Mississippi," since the presence of that state in 50th place spares them the shame of being ranked last.

Examples include rankings of educational achievement, business opportunities, political progressiveness, obesity rates, overall health, the poverty rate, life expectancy, or other objective criteria of the quality of life or government in the 50 states. The phrase is in use even among state government officials and journalists, though occasionally with a slight twist.

Mississippi's poor reputation is such a common trope in American culture that when Mississippi does indeed rank well in something, the phrase "Thank God for Mississippi" may get brought up just to discuss how it does not apply in the given circumstance. The saying comes from Mississippi's poor ranking as compared to the other 49 states, not from a global perspective.

Gary Stephen Webb (August 31, 1955 – December 10, 2004) was an American investigative journalist.

He began his career working for newspapers in Kentucky and Ohio, winning numerous awards, and building a reputation for investigative writing. Hired by the San Jose Mercury News, Webb contributed to the paper's Pulitzer Prize-winning coverage of the Loma Prieta earthquake.

Webb is best known for his "Dark Alliance" series, which appeared in The Mercury News in 1996. The series examined the origins of the crack cocaine trade in Los Angeles and claimed that members of the anti-communist Contra rebels in Nicaragua had played a major role in creating the trade, using cocaine profits to finance their fight against the government in Nicaragua. It also stated that the Contras may have acted with the knowledge and protection of the Central Intelligence Agency (CIA). The series provoked outrage, particularly in the Los Angeles African-American community, and led to four major investigations of its charges.

The Los Angeles Times and other major papers published articles suggesting the "Dark Alliance" claims were overstated and, in November 1996, Jerome Ceppos, the executive editor at Mercury News, wrote about being "in the eye of the storm". In May 1997, after an internal review, Ceppos stated that, although the story was correct on many important points, there were shortcomings in the writing, editing, and production of the series. He wrote that the series likely "oversimplified" the crack epidemic in America and the supposed "critical role" the dealers written about in the series played in it. Webb disagreed with this conclusion.

Webb resigned from The Mercury News in December 1997. He became an investigator for the California State Legislature, published a book based on the "Dark Alliance" series in 1998, and did freelance investigative reporting. He died by suicide on December 10, 2004.

The "Dark Alliance" series remains controversial. Critics view the series' claims as inaccurate or overstated, while supporters point to the results of a later CIA investigation as vindicating the series. The follow-up reporting in the Los Angeles Times and other papers has been criticised for focusing on problems in the series rather than re-examining the earlier CIA-Contra claims.

The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. Adams described the Zone System as "[...] not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40."

The technique is based on the late 19th century sensitometry studies of Hurter and Driffield. The Zone System provides photographers with a systematic method of precisely defining the relationship between the way they visualize the photographic subject and the final results. Although it originated with black-and-white sheet film, the Zone System is also applicable to roll film, both black-and-white and color, negative and reversal, and to digital photography.

🔗 Computing

In computer programming, program slicing is the computation of the set of program statements, the program slice, that may affect the values at some point of interest, referred to as a slicing criterion. Program slicing can be used in debugging to locate source of errors more easily. Other applications of slicing include software maintenance, optimization, program analysis, and information flow control.

Slicing techniques have been seeing a rapid development since the original definition by Mark Weiser. At first, slicing was only static, i.e., applied on the source code with no other information than the source code. Bogdan Korel and Janusz Laski introduced dynamic slicing, which works on a specific execution of the program (for a given execution trace). Other forms of slicing exist, for instance path slicing.

🔗 Philosophy 🔗 Philosophy/Contemporary philosophy 🔗 Philosophy/Ethics

Master–slave morality (German: Herren- und Sklavenmoral) is a central theme of Friedrich Nietzsche's works, particularly in the first essay of his book, On the Genealogy of Morality. Nietzsche argued that there were two fundamental types of morality: "master morality" and "slave morality". Master morality values pride and power, while slave morality values kindness, empathy, and sympathy. Master morality judges actions as good or bad (e.g. the classical virtues of the noble man versus the vices of the rabble), unlike slave morality, which judges by a scale of good or evil intentions (e. g. Christian virtues and vices, Kantian deontology).

For Nietzsche, a morality is inseparable from the culture which values it, meaning that each culture's language, codes, practices, narratives, and institutions are informed by the struggle between these two moral structures.

🔗 Technology 🔗 Computing 🔗 Computing/Early computers

The Water Integrator (Russian: Гидравлический интегратор) was an early analog computer built in the Soviet Union in 1936 by Vladimir Sergeevich Lukyanov. It functioned by careful manipulation of water through a room full of interconnected pipes and pumps. The water level in various chambers (with precision to fractions of a millimeter) represented stored numbers, and the rate of flow between them represented mathematical operations. This machine was capable of solving inhomogeneous differential equations.

The first versions of Lukyanov's integrators were rather experimental, made of tin and glass tubes, and each integrator could be used to solve only one problem. In the 1930s it was the only computer in the Soviet Union for solving partial differential equations.

In 1941, Lukyanov created a hydraulic integrator of modular design, which made it possible to assemble a machine for solving various problems. Two-dimensional and three-dimensional hydraulic integrators were designed.

In 1949–1955, an integrator in the form of standard unified units was developed at the NIISCHETMASH Institute. In 1955, the Ryazan plant of calculating and analytical machines began the serial production of integrators with the factory brand name “IGL” (russian: Интегратор Гидравлический Лукьянова - integrator of the Lukyanov hydraulic system). Integrators were widely distributed, delivered to Czechoslovakia, Poland, Bulgaria and China.

A water integrator was used in the design of the Karakum Canal in the 1940s, and the construction of the Baikal–Amur Mainline in the 1970s. Water analog computers were used in the Soviet Union until the 1980s for large-scale modelling. They were used in geology, mine construction, metallurgy, rocket production and other fields.

Currently, two hydraulic integrators are kept in the Polytechnic Museum in Moscow.

🔗 Languages 🔗 Iceland

The Basque–Icelandic pidgin was a Basque-based pidgin spoken in Iceland in the 17th century. It consisted of Basque, Germanic and Romance words.

Basque whale hunters who sailed to the Icelandic Westfjords used the pidgin as a means of rudimentary communication with locals. It might have developed in Westfjords, where manuscripts were written in the language, but since it had influences from many other European languages, it is more likely that it was created elsewhere and brought to Iceland by Basque sailors. Basque entries are mixed with words from Dutch, English, French, German and Spanish. The Basque–Icelandic pidgin is thereby not a mixture between Basque and Icelandic, but between Basque and other languages. It was named from the fact that it was written down in Iceland and translated into Icelandic.

Only a few manuscripts have been found containing Basque–Icelandic glossary, and knowledge about the pidgin is limited.
