🔗 Food and drink

Portable soup was a kind of dehydrated food used in the 18th and 19th centuries. It was a precursor of meat extract and bouillon cubes, and of industrially dehydrated food. It is also known as pocket soup or veal glew. It is a cousin of the glace de viande of French cooking. It was long a staple of seamen and explorers, for it would keep for many months or even years. In this context, it was a filling and nutritious dish. Portable soup of less extended vintage was, according to the 1881 Household Cyclopedia, "exceedingly convenient for private families, for by putting one of the cakes in a saucepan with about a quart of water, and a little salt, a basin of good broth may be made in a few minutes."

Cyclomatic complexity is a software metric used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program's source code. It was developed by Thomas J. McCabe, Sr. in 1976.

Cyclomatic complexity is computed using the control-flow graph of the program: the nodes of the graph correspond to indivisible groups of commands of a program, and a directed edge connects two nodes if the second command might be executed immediately after the first command. Cyclomatic complexity may also be applied to individual functions, modules, methods or classes within a program.

One testing strategy, called basis path testing by McCabe who first proposed it, is to test each linearly independent path through the program; in this case, the number of test cases will equal the cyclomatic complexity of the program.

The Sayfo or the Seyfo (lit. 'sword'; see below), also known as the Assyrian genocide, was the mass slaughter and deportation of Assyrian/Syriac Christians in southeastern Anatolia and Persia's Azerbaijan province by Ottoman forces and some Kurdish tribes during World War I.

The Assyrians were divided into mutually antagonistic churches, including the Syriac Orthodox Church, the Church of the East, and the Chaldean Catholic Church. Before World War I, they lived in mountainous and remote areas of the Ottoman Empire (some of which were effectively stateless). The empire's nineteenth-century centralization efforts led to increased violence and danger for the Assyrians.

Mass killing of Assyrian civilians began during the Ottoman occupation of Azerbaijan from January to May 1915, during which massacres were committed by Ottoman forces and pro-Ottoman Kurds. In Bitlis province, Ottoman troops returning from Persia joined local Kurdish tribes to massacre the local Christian population (including Assyrians). Ottoman forces and Kurds attacked the Assyrian tribes of Hakkari in mid-1915, driving them out by September despite the tribes mounting a coordinated military defense. Governor Mehmed Reshid initiated a genocide of all of the Christian communities in Diyarbekir province, including Syriac Christians, facing only sporadic armed resistance in some parts of Tur Abdin. Ottoman Assyrians living farther south, in present-day Iraq and Syria, were not targeted in the genocide.

The Sayfo occurred concurrently with and was closely related to the Armenian genocide, although the Sayfo is considered to have been less systematic. Local actors played a larger role than the Ottoman government, but the latter also ordered attacks on certain Assyrians. Motives for killing included a perceived lack of loyalty among some Assyrian communities to the Ottoman Empire and the desire to appropriate their land. At the 1919 Paris Peace Conference, the Assyro-Chaldean delegation said that its losses were 250,000 (about half the prewar population); the accuracy of this figure is unknown. They later revised their estimate to 275,000 dead at the Lausanne Conference in 1923. The Sayfo is less studied than the Armenian genocide. Efforts to have it recognized as a genocide began during the 1990s, spearheaded by the Assyrian diaspora. Although several countries acknowledge that Assyrians in the Ottoman Empire were victims of a genocide, this assertion is rejected by the Turkish government.

🔗 Books

The Victorian Internet: The Remarkable Story of the Telegraph and the Nineteenth Century's On-Line Pioneers is a 1998 book by Tom Standage. The book was first published in September 1998 through Walker & Company and discusses the development and uses of the electric telegraph during the second half of the 19th century and some of the similarities the telegraph shared with the Internet of the late 20th century.

The central thesis of the book argues that of these two technologies, it was the telegraph that was the more significant, since the ability to communicate globally at all in real-time was a qualitative shift, while according to Standage the change brought on by the modern Internet was merely a quantitative shift.

🔗 Novels

I, Libertine is a literary hoax novel that began as a practical joke by late-night radio raconteur Jean Shepherd who aimed to lampoon the process of determining best-selling books. After generating substantial attention for a novel that didn't actually exist, Shepherd approved a 1956 edition of the book written mainly by Theodore Sturgeon — which became an actual best-seller, with all profits donated to charity.

Yakovlevian torque (also known as occipital bending (OB) or counterclockwise brain torque) is the tendency of the right side of the human brain to be warped slightly forward relative to the left and the left side of the human brain to be warped slightly backward relative to the right. This is responsible for certain asymmetries, such as how the lateral sulcus of the human brain is often longer and less curved on the left side of the brain relative to the right. Stated in another way, Yakovlevian Torque can be defined by the existence of right-frontal and left-occipital petalias, which are protrusions of the surface of one hemisphere relative to the other. It is named for Paul Ivan Yakovlev (1894–1983), a Russian-American neuroanatomist from Harvard Medical School.

In computer science, Linda is a model of coordination and communication among several parallel processes operating upon objects stored in and retrieved from shared, virtual, associative memory. It was developed by Sudhir Ahuja at AT&T Bell Laboratories in collaboration with David Gelernter and Nicholas Carriero at Yale University in 1986.

🔗 Urban studies and planning

Marchetti's constant is the average time spent by a person for commuting each day, which is approximately one hour. It is named after Italian physicist Cesare Marchetti, though Marchetti himself attributed the "one hour" finding to transportation analyst and engineer Yacov Zahavi. Marchetti posits that although forms of urban planning and transport may change, and although some live in villages and others in cities, people gradually adjust their lives to their conditions (including location of their homes relative to their workplace) such that the average travel time stays approximately constant. Ever since Neolithic times, people have kept the average time spent per day for travel the same, even though the distance may increase due to the advancements in the means of transportation. In his 1934 book Technics and Civilization, Lewis Mumford attributes this observation to Bertrand Russell:

Mr. Bertrand Russell has noted that each improvement in locomotion has increased the area over which people are compelled to move: so that a person who would have had to spend half an hour to walk to work a century ago must still spend half an hour to reach his destination, because the contrivance that would have enabled him to save time had he remained in his original situation now—by driving him to a more distant residential area—effectually cancels out the gain.

A related concept is that of Zahavi, who also noticed that people seem to have a constant "travel time budget", that is, "a stable daily amount of time that people make available for travel." David Metz, former chief scientist at the Department of Transport, UK, cites data of average travel time in Britain drawn from the British National Travel Survey in support of Marchetti's and Zahavi's conclusions. The work casts doubt on the contention that investment in infrastructure saves travel time. Instead, it appears from Metz's figures that people invest travel time saved in travelling a longer distance, a particular example of Jevons paradox described by the Lewis–Mogridge position. Because of the constancy of travel times as well as induced travel, Robert Cervero has argued that the World Bank and other international aid agencies evaluate transportation investment proposals in developing and rapidly motorizing cities less on the basis of potential travel-time savings and more on the accessibility benefits they confer.

Mike the Headless Chicken (April 20, 1945 – March 17, 1947), also known as Miracle Mike, was a Wyandotte chicken that lived for 18 months after his head had been cut off. Although the story was thought by many to be a hoax, the bird's owner took him to the University of Utah in Salt Lake City to establish the facts.
