π The Plague
The Plague (French: La Peste) is a novel by Albert Camus, published in 1947, that tells the story of a plague sweeping the French Algerian city of Oran. It asks a number of questions relating to the nature of destiny and the human condition. The characters in the book, ranging from doctors to vacationers to fugitives, all help to show the effects the plague has on a populace.
The novel is believed to be based on the cholera epidemic that killed a large percentage of Oran's population in 1849 following French colonization, but the novel is placed in the 1940s. Oran and its surroundings were struck by disease multiple times before Camus published this novel. According to a research report by the Centers for Disease Control and Prevention, Oran was decimated by the plague in 1556 and 1678, but all later outbreaks, in 1921 (185 cases), 1931 (76 cases), and 1944 (95 cases), were very far from the scale of the epidemic described in the novel.
The Plague is considered an existentialist classic despite Camus' objection to the label. The narrative tone is similar to Kafka's, especially in The Trial whose individual sentences potentially have multiple meanings, the material often pointedly resonating as stark allegory of phenomenal consciousness and the human condition.
Camus included a dim-witted character misreading The Trial as a mystery novel as an oblique homage. The novel has been read as an allegorical treatment of the French resistance to Nazi occupation during World War II. Additionally, he further illustrates the human reaction towards the "absurd". The Plague represents how the world deals with the philosophical notion of the Absurd, a theory that Camus himself helped to define.

π Thorium-Based Nuclear Power
Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium. According to proponents, a thorium fuel cycle offers several potential advantages over a uranium fuel cycleβincluding much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production. However, development of thorium power has significant start-up costs. Proponents also cite the low weaponization potential as an advantage of thorium due to how difficult it is to weaponize the specific uranium-233/232 and plutonium-238 isotopes produced by thorium reactors, while critics say that development of breeder reactors in general (including thorium reactors, which are breeders by nature) increases proliferation concerns. As of 2020, there are no operational thorium reactors in the world.
A nuclear reactor consumes certain specific fissile isotopes to produce energy. Currently, the most common types of nuclear reactor fuel are:
- Uranium-235, purified (i.e. "enriched") by reducing the amount of uranium-238 in natural mined uranium. Most nuclear power has been generated using low-enriched uranium (LEU), whereas high-enriched uranium (HEU) is necessary for weapons.
- Plutonium-239, transmuted from uranium-238 obtained from natural mined uranium.
Some believe thorium is key to developing a new generation of cleaner, safer nuclear power. According to a 2011 opinion piece by a group of scientists at the Georgia Institute of Technology, considering its overall potential, thorium-based power "can mean a 1000+ year solution or a quality low-carbon bridge to truly sustainable energy sources solving a huge portion of mankindβs negative environmental impact."
After studying the feasibility of using thorium, nuclear scientists Ralph W. Moir and Edward Teller suggested that thorium nuclear research should be restarted after a three-decade shutdown and that a small prototype plant should be built.

π Algocracy
Government by algorithm (also known as algorithmic regulation, regulation by algorithms, algorithmic governance, algocratic governance, algorithmic legal order or algocracy) is an alternative form of government or social ordering, where the usage of computer algorithms, especially of artificial intelligence and blockchain, is applied to regulations, law enforcement, and generally any aspect of everyday life such as transportation or land registration. The term 'government by algorithm' appeared in academic literature as an alternative for 'algorithmic governance' in 2013. A related term, algorithmic regulation is defined as setting the standard, monitoring and modification of behaviour by means of computational algorithms β automation of judiciary is in its scope.
Government by algorithm raises new challenges that are not captured in the e-government literature and the practice of public administration. Some sources equate cyberocracy, which is a hypothetical form of government that rules by the effective use of information, with algorithmic governance, although algorithms are not the only means of processing information. Nello Cristianini and Teresa Scantamburlo argued that the combination of a human society and an algorithmic regulation forms a social machine.

π Fuzzy Logic
Fuzzy logic is a form of many-valued logic in which the truth values of variables may be any real number between 0 and 1 both inclusive. It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false. By contrast, in Boolean logic, the truth values of variables may only be the integer values 0 or 1.
The term fuzzy logic was introduced with the 1965 proposal of fuzzy set theory by Lotfi Zadeh. Fuzzy logic had, however, been studied since the 1920s, as infinite-valued logicβnotably by Εukasiewicz and Tarski.
Fuzzy logic is based on the observation that people make decisions based on imprecise and non-numerical information. Fuzzy models or sets are mathematical means of representing vagueness and imprecise information (hence the term fuzzy). These models have the capability of recognising, representing, manipulating, interpreting, and utilising data and information that are vague and lack certainty.
Fuzzy logic has been applied to many fields, from control theory to artificial intelligence.

π MΓ©nage Problem
In combinatorial mathematics, the mΓ©nage problem or problΓ¨me des mΓ©nages asks for the number of different ways in which it is possible to seat a set of male-female couples at a round dining table so that men and women alternate and nobody sits next to his or her partner. This problem was formulated in 1891 by Γdouard Lucas and independently, a few years earlier, by Peter Guthrie Tait in connection with knot theory. For a number of couples equal to 3, 4, 5, ... the number of seating arrangements is
- 12, 96, 3120, 115200, 5836320, 382072320, 31488549120, ... (sequence A059375 in the OEIS).
Mathematicians have developed formulas and recurrence equations for computing these numbers and related sequences of numbers. Along with their applications to etiquette and knot theory, these numbers also have a graph theoretic interpretation: they count the numbers of matchings and Hamiltonian cycles in certain families of graphs.

π Cyclomatic Complexity
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.

π OK Soda
OK Soda was a soft drink created by The Coca-Cola Company in 1993 that courted the American Generation X demographic with unusual advertising tactics, including neo-noir design, chain letters and deliberately negative publicity. After the soda did not sell well in select test markets, it was officially declared out of production in 1995 before reaching nationwide distribution. The drink's slogan was "Things are going to be OK."

π Duenos Inscription
The Duenos inscription is one of the earliest known Old Latin texts, variously dated from the 7th to the 5th century BC. It is inscribed on the sides of a kernos, in this case a trio of small globular vases adjoined by three clay struts. It was found by Heinrich Dressel in 1880 on the Quirinal Hill in Rome. The kernos is part of the collection of the Staatliche Museen in Berlin (inventory no. 30894,3).
The inscription is written right to left in three units, without spaces to separate words. It is difficult to translate, as some letters are hard to distinguish, particularly since they cannot always be deduced by context. The absence of spaces causes additional difficulty in assigning the letters to the respective words.

π Teasmade
A teasmade is a machine for making tea automatically, which was once common in the United Kingdom and some British Commonwealth countries. Teasmades generally include an analogue alarm clock and are designed to be used at the bedside, to ensure tea is ready first thing in the morning. Although crude versions existed in Victorian times, they only became practical with the availability of electric versions in the 1930s. They reached their peak in popularity in the 1960s and 1970s, since when their use has declined, but they are now enjoying a revival, partly as a retro novelty item.
The name teasmade is an example of a genericised trademark, now commonly used to refer to any automatic tea-making appliance.
π Vim, 25 years since initial release
Vim (; a contraction of Vi IMproved) is a clone, with additions, of Bill Joy's vi text editor program for Unix. Vim's author, Bram Moolenaar, based it upon the source code for a port of the Stevie editor to the Amiga and released a version to the public in 1991. Vim is designed for use both from a command-line interface and as a standalone application in a graphical user interface. Vim is free and open-source software and is released under a license that includes some charityware clauses, encouraging users who enjoy the software to consider donating to children in Uganda. The license is compatible with the GNU General Public License through a special clause allowing distribution of modified copies "under the GNU GPL version 2 or any later version".
Since its release for the Amiga, cross-platform development has made it available on many other systems. In 2006, it was voted the most popular editor amongst Linux Journal readers; in 2015 the Stack Overflow developer survey found it to be the third most popular text editor, and the fifth most popular development environment in 2019.
