🔗 Computer science

In computer science, a succinct data structure is a data structure which uses an amount of space that is "close" to the information-theoretic lower bound, but (unlike other compressed representations) still allows for efficient query operations. The concept was originally introduced by Jacobson to encode bit vectors, (unlabeled) trees, and planar graphs. Unlike general lossless data compression algorithms, succinct data structures retain the ability to use them in-place, without decompressing them first. A related notion is that of a compressed data structure, in which the size of the data structure depends upon the particular data being represented.

Suppose that ${\displaystyle Z}$ is the information-theoretical optimal number of bits needed to store some data. A representation of this data is called:

• implicit if it takes ${\displaystyle Z+O(1)}$ bits of space,
• succinct if it takes ${\displaystyle Z+o(Z)}$ bits of space, and
• compact if it takes ${\displaystyle O(Z)}$ bits of space.

For example, a data structure that uses ${\displaystyle 2Z}$ bits of storage is compact, ${\displaystyle Z+{\sqrt {Z}}}$ bits is succinct, ${\displaystyle Z+\lg Z}$ bits is also succinct, and ${\displaystyle Z+3}$ bits is implicit.

Implicit structures are thus usually reduced to storing information using some permutation of the input data; the most well-known example of this is the heap.

🔗 Books 🔗 Anthropology 🔗 Mythology

An Instinct for Dragons is a book by University of Central Florida anthropologist, David E. Jones, in which he seeks to explain the universality of dragon images in the folklore of human societies. In the introduction, Jones conducts a survey of dragon myths from cultures around the world and argues that certain aspects of dragons or dragon-like mythical creatures are found very widely. He claims that even the Inuit have a reptilian dragon-like monster, even though (living in a frigid environment unsuited for cold-blooded animals) they had never seen an actual reptile.

Jones then argues against the common hypothesis that dragon myths might be motivated by primitive discoveries of dinosaur fossils (he argues that there are widespread traits of dragons in folklore which are not observable from fossils), and claims that the common traits of dragons seem to be an amalgam of the principal predators of our ancestral hominids, which he names as the raptors, great cats (especially leopards) and pythons.

The hypothesis to which Jones conforms is that over millions of years of evolution, members of a species will evolve an instinctive fear of their predators, and he proposes ways in which these fearful images may be merged in artistic or cultural expression to create the dragon image and, perhaps, other kinds of hybrid monster.

Finally he suggests sociological reasons for why such images may be perceived differently at different stages of a culture to try to explain why Chinese dragons are considered basically good and representative of government, but the great majority (although not all) European dragons are evil and often represent chaos.

The International Day of Happiness is celebrated worldwide every year on 20 March, and was originally conceptualized and founded in 2006 by Jayme Illien, CEO of the United Nations New World Order project, to advance happiness as a fundamental human right for all human beings, and happytalism, as new economic system, theory, and philosophy, which achieves the United Nations global goals, and the happiness, well-being, and freedom of all life on earth.

The next international day of happiness is March 20, 2021.

The 2020 International Day of Happiness campaign theme is ‘Happiness For All, Together'”. To celebrate, UNIDOHappiness, the UN secretariat for the International Day Of Happiness, is calling on all 7.8 billion people and all 206 nations and territories, to take the "Ten Steps to Global Happiness" challenge and call to action. The ten steps to global happiness are "ten easy steps any individual, organization, or country, can take on the international day of happiness, and throughout happiness week, to celebrate the international day of happiness, while also advancing the happiness, wellbeing, and freedom of all life on earth by 2050, when the United Nations forecasts global population to reach 10 billion". The first step is “Tell Everyone", which is designed "spread the word" to increase global awareness about the very existence of the international day of happiness, and the UN's unanimous recognition of happiness as a human right, as well as happiness as an approach to sustainable economic and human development.

The 2006 origin and inspiration for creating the international day of happiness initially came from founder Jayme Illien's belief that the happiness, wellbeing, and freedom of all life on earth is the ultimate purpose of every human being, nation, and society. Illien developed his vision for global happiness as humanity's ultimate purpose, through a life spent on the frontlines saving orphaned and abandoned children fleeing war, genocide, and extreme poverty, and theorizing about solutions to the human condition, and the great challenges facing humankind, after he himself was abandoned as an orphan, and rescued from a roadside in India in 1980, by missionaries of Mother Teresa, who first named him Adam, and sent him to live in America.

In 2006, Illien first presented the new economic theory, "happytalism", as a new economic system for the 21st century and beyond, to replace old world economic systems (from 5th to 20th century) such as capitalism, communism, socialism, mercantilism, colonialism, feudalism, racism, and sexism, among others - all created more than 150-1000 years ago. In 2006, Illien successfully demonstrated to prominent economists, academics, political scientists, philosophers, presidents, prime ministers, and heads of state, all in a position to advance happytalism as a solution to the great challenges facing humankind, that the new economic theory was the solution to the world's most pressing and greatest human development challenges and opportunities. However, despite Illien's successful proof of happytalism as a new economic system to replace capitalism and other old world, archaic, obsolete economic systems and models, this eminent multidisciplinary group of experts rejected the idea, and refused to further evaluate or consider the new economic theory due to what Illien, and co founder, Ndaba Mandela, believed were "old world and obsolete tyranny of the status quo, entrenched racist and sexist bias, mindset, incompetence, failed intelligence and intellectual vitality, and an archaic, potentially criminal world view that is a gross violation of global ethical norms, and implicit fiduciary responsibility to all humanity, incapable of seeing and doing what is right and necessary to advance humanity forward".

In 2008, in response to the rejection of Illien's concept of "happytalism" as a new economic theory, and convinced of happytalism as the solution to humanity's great challenges and opportunities in the 21st century and beyond, Illien launched the United Nations New World Order project with co founder Ndaba Mandela, grandson of Nelson Mandela, former president of South Africa, who led the revolution and movement that ended apartheid, and "gave birth to a new nation, a new political party, and a new era of democratic governance in South Africa, and the African Continent.". The United Nations New World Order Project launched in 2008 envisioned, among several UN based policy initiatives, the creation of a United Nations sanctioned "international day of happiness", as a global day of awareness that commemorates and recognizes happiness as a human right, and a fundamental, universal human goal, and calls for a new happiness centric human development paradigm which achieves the happiness, wellbeing, and freedom of all life on earth.

Illien drew inspiration for the idea of establishing the international day of happiness from the founders of the United States of America, and authors of the US Declaration of Independence, as well as, the founders of the United Nations, and UN Day, and the authors of the United Nations Charter. Illien believed that an "international day of happiness", established with, and recognized by, a new UN resolution, with the support of all 193 UN member countries, would provide the essential, unique, and broad-based, wide-ranging democratic support, international credibility, and worldwide legal legitimacy, for a new global day of happiness for humanity, which in turn, would enable future generations to eventually, objectively consider the concept of happytalism as a new economic system to solve to the great challenges facing humanity, thereby placing the fate and future of happytalism directly in the hands of the people and future generations.

In 2012, the United Nations General Assembly adopted UN resolution 66 281: International Day of Happiness with the unanimous consensus of all 193 Member States, and the support of then UN Secretary General Ban Ki moon, declaring March 20 as the international day of happiness. Illien chose 20 March for its significance as the March equinox, a universal phenomenon felt simultaneously by all of humankind.

In 2012, the United Nations also hosted the first high level meeting on Happiness and Well-being: Defining A New Economic Paradigm, at which UN Secretary General Ban Ki moon declared:

Later in 2012, then UN Secretary General Ban Ki moon stated in his closing remarks to the 66th session of the UN General Assembly:

On January 22, 2013, then UN Secretary General Ban Ki moon stated in an address to the UN General Assembly:

On March 20, 2013, the first ever international day of happiness was celebrated with the launch of UNIDOHappiness, and the "Ten Steps to Global Happiness" campaign theme, which has since become an annual tradition.

Every 20 March since 2013, the International Day of Happiness is celebrated in 193 UN Member states, 2 observer states, and 11 territories.

🔗 Olympics 🔗 Athletics

The men's marathon at the 1904 Summer Olympics in St. Louis, United States, took place on August 30 of that year, over a distance of 24.85 miles (40 km).

The race was run during the hottest part of the day on dusty country roads with minimal water supply; while thirty-two athletes representing four nations competed, only 14 managed to complete the race, which was a bizarre affair due to poor organization and officiating. While Fred Lorz was greeted as the apparent winner, he was later disqualified as he had hitched a ride in a car for part of the race. The actual winner, Thomas Hicks, was near collapse and hallucinating by the end of the race, a side effect of being administered brandy, raw eggs, and strychnine by his trainers. The fourth-place finisher, Andarín Carvajal, took a nap during the race after eating spoiled apples.

The Boirault machine (French: Appareil Boirault), was an early French experimental landship, designed in 1914 and built in early 1915. It has been considered as "another interesting ancestor of the tank", and described as a "rhomboid-shaped skeleton tank without armour, with single overhead track". Ultimately, the machine was deemed impractical and was nicknamed Diplodocus militaris. It preceded the design and development of the English Little Willie tank by six months.

🔗 Psychology

Cabin fever refers to the distressing claustrophobic irritability or restlessness experienced when a person, or group, is stuck at an isolated location or in confined quarters for an extended period of time. A person may be referred to as stir-crazy, derived from the use of stir to mean 'prison'.

A person may experience cabin fever in a situation such as being isolated within a vacation cottage out in the country, spending long periods underwater in a submarine, or being otherwise isolated from civilization. During cabin fever, a person may experience sleepiness or sleeplessness, have a distrust of anyone they are with, or have an urge to go outside even in adverse conditions such as poor weather or limited visibility. The concept is also invoked humorously to indicate simple boredom from being home alone for an extended period of time.

Cabin fever is not itself a disease and there is no prognosis. However, related symptoms can lead the sufferer to make irrational decisions that could potentially threaten their life or the life of the group with whom they are confined. Some examples would be suicide or paranoia, or leaving the safety of a cabin during a terrible snow storm that one may be stuck in.

🔗 Board and table games

18XX is the generic term for a series of board games that, with a few exceptions, recreate the building of railroad corporations during the 19th century; individual games within the series use particular years in the 19th century as their title (usually the date of the start of railway development in the area of the world they cover), or "18" plus a two or more letter geographical designator (such as 18EU for a game set in the European Union). The games 2038, set in the future, and Poseidon and Ur, 1830 BC, both set in ancient history, are also regarded as 18XX titles as their game mechanics and titling nomenclature are similar despite variance from the common railroad/stock-market theme.

The 18XX series has its origins in the game 1829, first produced by Francis Tresham in the mid-1970s. 1829 was chosen as it was the year of the Rainhill Trials. 1830 was produced by Avalon Hill in 1986, and was the first game of the series widely available in the United States; it is seen as the basic 18XX game by the U.S. audience.

In addition to traditionally published games, the 18XX series has spawned self-published variants and games published by low-volume game companies.

With few exceptions (such as 2038), 18XX titles are multiplayer board games without random variables in their game mechanics.
