From its beginnings in the 1960s, writing software has evolved into a profession concerned with how best to maximize the quality of software and of how to create it. Quality can refer to how maintainable software is, to its stability, speed, usability, testability, readability, size, cost, security, and number of flaws or "bugs", as well as to less measurable qualities like elegance, conciseness, and customer satisfaction, among many other attributes. How best to create high quality software is a separate and controversial problem covering software design principles, so-called "best practices" for writing code, as well as broader management issues such as optimal team size, process, how best to deliver software on time and as quickly as possible, work-place "culture", hiring practices, and so forth. All this falls under the broad rubric of software engineering.

Tadeusz Kościuszko (1746–1817), a prominent figure in the history of the Polish-Lithuanian Commonwealth and the American Revolution, made several wills, notably one in 1798 stipulating that the proceeds of his American estate be spent on freeing and educating African-American slaves, including those of his friend Thomas Jefferson, whom he named as the will's executor. Jefferson refused the executorship and the will was beset by legal complications, including the discovery of later wills. Jefferson's refusal incited discussion in the 19th, 20th, and 21st centuries. Kościuszko returned to Europe in 1798 and lived there until his 1817 death in Switzerland. In the 1850s, what was left of the money in Kościuszko's U.S. trust was turned over by the U.S. Supreme Court to his heirs in Europe.

Hoag's Object is a non-typical galaxy of the type known as a ring galaxy. The galaxy is named after Arthur Hoag who discovered it in 1950 and identified it as either a planetary nebula or a peculiar galaxy with eight billion stars, spanning roughly 100,000 light years.

🔗 Singapore

No U-Turn Syndrome (NUTS) is a term first coined by Singaporean entrepreneur Sim Wong Hoo to prominently describe the social behaviour of Singaporeans having a mindset of compliance to higher authorities before proceeding with any action. He makes a comparison of traffic rules in Singapore to those found overseas, to describe the phenomenon. In Singapore, drivers are not allowed to make a U-turn unless a sign specifically allows them to do so, while in some other countries drivers may make U-turns freely so long as a "No U-turn" sign is not present. Following that, this analogy is used to explain the red tape he has encountered with hard-nosed bureaucrats, which in turn stifles the very creativity that the Singaporean government has been trying to promote in the recent years.

NUTS is also considered as one of the major criticisms of the rigid Singapore education system, where students are taught from a young age to obey instructions in an unquestioning manner, in a society where grades and paper certification are emphasised at the expense of some life skills.

In 2003, the term was referred to by Singaporean MPs during discussions about encouraging entrepreneurship. Five MPs said that "the biggest hurdle for Singaporeans in creating a pro-enterprise environment is the Nuts mentality."

🔗 Music/Music genres

Black MIDI is a music genre consisting of compositions that use MIDI files to create a song or a remix containing a large number of notes, typically in the thousands, millions, billions, or even trillions. People who make black MIDIs are known as blackers. However, there are no specific criteria of what is considered "black"; as a result, pinpointing the exact origin of black MIDI is impossible.

The Lazy Dog (sometimes called a Red Dot Bomb or Yellow Dog Bomb) is a type of small, unguided kinetic projectile used by the U.S. Air Force. It measured about 1.75 inches (44 mm) in length, 0.5 inches (13 mm) in diameter, and weighed about 0.7 ounces (20 g).

The weapons were designed to be dropped from an aircraft. They contained no explosive charge but as they fell they would develop significant kinetic energy making them lethal and able to easily penetrate soft cover such as jungle canopy, several inches of sand, or light armor. Lazy Dog munitions were simple and relatively cheap; they could be dropped in huge numbers in a single pass. Though their effects were often no less deadly than other projectiles, they did not leave unexploded ordnance (UXO) that could be active years after a conflict ended.

Lazy Dog projectiles were used primarily during the Korean and the Vietnam Wars.

🔗 Computing

OpenMusic (OM) is an object-oriented visual programming environment for musical composition based on Common Lisp. It may also be used as an all-purpose visual interface to Lisp programming. At a more specialized level, a set of provided classes and libraries make it a very convenient environment for music composition.

The Nicomachean Ethics (; Ancient Greek: Ἠθικὰ Νικομάχεια, Ēthika Nikomacheia) is the name normally given to Aristotle's best-known work on ethics. The work, which plays a pre-eminent role in defining Aristotelian ethics, consists of ten books, originally separate scrolls, and is understood to be based on notes from his lectures at the Lyceum. The title is often assumed to refer to his son Nicomachus, to whom the work was dedicated or who may have edited it (although his young age makes this less likely). Alternatively, the work may have been dedicated to his father, who was also called Nicomachus.

The theme of the work is a Socratic question previously explored in the works of Plato, Aristotle's friend and teacher, of how men should best live. In his Metaphysics, Aristotle described how Socrates, the friend and teacher of Plato, had turned philosophy to human questions, whereas pre-Socratic philosophy had only been theoretical. Ethics, as now separated out for discussion by Aristotle, is practical rather than theoretical, in the original Aristotelian senses of these terms. In other words, it is not only a contemplation about good living, because it also aims to create good living. It is therefore connected to Aristotle's other practical work, the Politics, which similarly aims at people becoming good. Ethics is about how individuals should best live, while the study of politics is from the perspective of a law-giver, looking at the good of a whole community.

The Nicomachean Ethics is widely considered one of the most important historical philosophical works, and had an important impact upon the European Middle Ages, becoming one of the core works of medieval philosophy. It therefore indirectly became critical in the development of all modern philosophy as well as European law and theology. Many parts of the Nicomachean Ethics are well known in their own right, within different fields. In the Middle Ages, a synthesis between Aristotelian ethics and Christian theology became widespread, in Europe as introduced by Albertus Magnus. While various philosophers had influenced Christendom since its earliest times, in Western Europe Aristotle became "the Philosopher". The most important version of this synthesis was that of Thomas Aquinas. Other more "Averroist" Aristotelians such as Marsilius of Padua were controversial but also influential. (Marsilius is for example sometimes said to have influenced the controversial English political reformer Thomas Cromwell.)

A critical period in the history of this work's influence is at the end of the Middle Ages, and beginning of modernity, when several authors such as Francis Bacon and Thomas Hobbes, argued forcefully and largely successfully that the medieval Aristotelian tradition in practical thinking had become a great impediment to philosophy in their time. However, in more recent generations, Aristotle's original works (if not those of his medieval followers) have once again become an important source. More recent authors influenced by this work include Alasdair MacIntyre, G. E. M. Anscombe, Hans-Georg Gadamer, Martha Nussbaum and Avital Ronell.

🔗 Urban studies and planning

The Lewis–Mogridge position, named after David Lewis and Martin J. H. Mogridge, was formulated in 1990 and observes that as more roads are built, more traffic consequently fills these roads. Speed gains from some new roads can disappear within months, if not weeks. Sometimes, new roads help to reduce traffic jams, but in most cases, the congestion is only shifted to another junction.

The position reads traffic expands to meet the available road space (Mogridge, 1990). It is generally referred to as induced demand in the transport literature, and was posited as the "Iron Law of Congestion" by Anthony Downs. It is a special case of Jevons paradox (where the resource in question is traffic capacity), and relates to the Marchetti's constant (average commute times are similar in widely varying conditions).

Following the position, it is not generally concluded that new roads are never justified but that their development needs to consider the whole traffic system, which means understanding the movement of goods and people in detail as well as the motivation behind the movement.

The position is often used to understand problems caused by private transport such as congested roads in cities and on motorways. It can also be used to explain the success of schemes such as the London congestion charge.

The position, however, is not confined to private transport. Mogridge, a British transport researcher, concluded also that all road investment in a congested urban area will have the effect of reducing the average speed of the transport system as a whole: road and public transport. The relationship and overall equilibria are also known as the "Downs–Thomson paradox". However, according to Downs, the link between average speeds on public transport and private transport applies only "to regions in which the vast majority of peak-hour commuting is done on rapid transit systems with separate rights of way. Central London is an example, since in 2001 around 85 percent of all morning peak-period commuters into that area used public transit (including 77 percent on separate rights of way) and only 11 percent used private cars. When peak-hour travel equilibrium has been reached between the subway system and the major commuting roads, then the travel time required for any given trip is roughly equal on both modes."

🔗 Psychology

The curse of knowledge is a cognitive bias that occurs when an individual, communicating with other individuals, unknowingly assumes that the others have the background to understand. This bias is also called by some authors the curse of expertise, although that term is also used to refer to various other phenomena.

For example, in a classroom setting, teachers have difficulty teaching novices because they cannot put themselves in the position of the student. A brilliant professor might no longer remember the difficulties that a young student encounters when learning a new subject. This curse of knowledge also explains the danger behind thinking about student learning based on what appears best to faculty members, as opposed to what has been verified with students.
