๐ Trojan Room Coffee Pot
The Trojan Room coffee pot was a coffee machine located in the Computer Laboratory of the University of Cambridge, England. Created in 1991 by Quentin Stafford-Fraser and Paul Jardetzky, it was migrated from their laboratory network to the web in 1993 becoming the world's first webcam.
To save people working in the building the disappointment of finding the coffee machine empty after making the trip to the room, a camera was set up providing a live picture of the coffee pot to all desktop computers on the office network. After the camera was connected to the Internet a few years later, the coffee pot gained international renown as a feature of the fledgling World Wide Web, until being retired in 2001.

๐ Planck Scale
In particle physics and physical cosmology, Planck units are a system of units of measurement defined exclusively in terms of four universal physical constants: c, G, ฤง, and kB. Expressing one of these physical constants in terms of Planck units yields a numerical value of 1. They are a system of natural units, defined using fundamental properties of nature (specifically, properties of free space) rather than properties of a chosen prototype object. Originally proposed in 1899 by German physicist Max Planck, they are relevant in research on unified theories such as quantum gravity.
The term Planck scale refers to quantities of space, time, energy and other units that are similar in magnitude to corresponding Planck units. This region may be characterized by particle energies of around 1019ย GeV or 109ย J, time intervals of around 10โ43ย s and lengths of around 10โ35ย m (approximately the energy-equivalent of the Planck mass, the Planck time and the Planck length, respectively). At the Planck scale, the predictions of the Standard Model, quantum field theory and general relativity are not expected to apply, and quantum effects of gravity are expected to dominate. One example is represented by the conditions in the first 10โ43 seconds of our universe after the Big Bang, approximately 13.8 billion years ago.
The four universal constants that, by definition, have a numerical value 1 when expressed in these units are:
- c, the speed of light in vacuum,
- G, the gravitational constant,
- ฤง, the reduced Planck constant, and
- kB, the Boltzmann constant.
Variants of the basic idea of Planck units exist, such as alternate choices of normalization that give other numerical values to one or more of the four constants above.
๐ Tragedy of the Anticommons
The tragedy of the anticommons is a type of coordination breakdown, in which a commons does not emerge, even when general access to resources or infrastructure would be a social good. It is a mirror-image of the older concept of tragedy of the commons, in which numerous rights holders' combined use exceeds the capacity of a resource and depletes or destroys it. The "tragedy of the anticommons" covers a range of coordination failures, including patent thickets and submarine patents. Overcoming these breakdowns can be difficult, but there are assorted means, including eminent domain, laches, patent pools, or other licensing organizations.
The term originally appeared in Michael Heller's 1998 article of the same name and is the thesis of his 2008 book. The model was formalized by James M. Buchanan and Yong Yoon. In a 1998 Science article, Heller and Rebecca S. Eisenberg, while not disputing the role of patents in general in motivating invention and disclosure, argue that biomedical research was one of several key areas where competing patent rights could actually prevent useful and affordable products from reaching the marketplace.

๐ Today Is International Day of Happiness
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 โHappiness For All, Together'โ. 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 โTell 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 aย 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.
On the 3rd ever international day of happiness, UN Secretary Ban Ki moon said,

๐ GNU Guix
GNU Guix () is a functional cross-platform package manager and a tool to instantiate and manage Unix-like operating systems, based on the Nix package manager. Configuration and package recipes are written in Guile Scheme. GNU Guix is the default package manager of the GNU Guix System distribution.
Differing from traditional package managers, Guix (like Nix) utilizes a purely functional deployment model where software is installed into unique directories generated through cryptographic hashes. All dependencies for each software are included within each hash. This solves the problem of dependency hell, allows multiple versions of the same software to coexist and makes packages portable and reproducible. Performing scientific computations in a Guix setup has been proposed as a promising response to the replication crisis.
The development of GNU Guix is intertwined with the GNU Guix System, an installable operating system distribution using the Linux-libre kernel and GNU Shepherd init system.
๐ Erdstall
An erdstall is a type of tunnel found across Europe. They are of unknown origin but are believed to date from the Middle Ages. A variety of purposes have been theorized, including that they were used as escape routes or hiding places, but the most prominent theory is that they served a religious or spiritual purpose.

๐ Overburden Conveyor Bridge F60
F60 is the series designation of five overburden conveyor bridges used in brown coal (lignite) opencast mining in the Lusatian coalfields in Germany. They were built by the former Volkseigener Betrieb TAKRAF in Lauchhammer and are the largest movable technical industrial machines in the world. As overburden conveyor bridges, they transport the overburden which lies over the coal seam. The cutting height is 60ย m (200ย ft), hence the name F60. In total, the F60 is up to 80ย m (260ย ft) high and 240ย m (790ย ft) wide; with a length of 502ย m (1,647ย ft), it is described as the lying Eiffel tower, making these behemoths not only the longest vehicle ever madeโbeating Seawise Giant, the longest shipโbut the largest vehicle by physical dimensions ever made by humankind. In operating condition, it weighs 13,600ย metricย tons making the F60 also one of the heaviest land vehicles ever made, beaten only by Bagger 293, which is a giant bucket-wheel excavator. Nevertheless, despite its immense size, it is operated by only a crew of 14.
The first conveyor bridge was built from 1969 to 1972, being equipped with a feeder bridge in 1977. The second was built from 1972 to 1974, having been equipped with a feeder bridge during construction. The third conveyor bridge was built from 1976 to 1978, being provided with a feeder bridge in 1985. The fourth and fifth conveyor bridges were built 1986โ1988 and 1988โ1991 respectively.
There are still four F60s in operation in the Lusatian coalfields today: in the brown coal opencast mines in Jรคnschwalde (Brandenburg, near Jรคnschwalde Power Station), Welzow-Sรผd (Brandenburg, near Schwarze Pumpe Power Station), Nochten and Reichwalde (Saxony, both near Boxberg Power Station). The fifth F60, the last one built, is in Lichterfeld-Schacksdorf and is accessible to visitors.

๐ Here is one hand
Here is one hand is an epistemological argument created by George Edward Moore in reaction against philosophical skepticism and in support of common sense.
The argument takes the following form:
- Here is one hand,
- And here is another.
- There are at least two external objects in the world.
- Therefore, an external world exists.
๐ Hokkaido characters
The Hokkaido characters (ๅๆตท้็ฐไฝๆๅญ, hokkaidล itai moji), also known as Aino characters (ใขใคใใขใธ, aino moji) or Ainu characters (ใขใคใๆๅญ, ainu moji), are a set of characters discovered around 1886 on the Japanese island of Hokkaido. At the time of their discovery, they were believed to be a genuine script, but this view is not generally supported today.
