Fifth-generation warfare (5GW) is warfare that is conducted primarily through non-kinetic military action, such as social engineering, misinformation, cyberattacks, along with emerging technologies such as artificial intelligence and fully autonomous systems. Fifth generation warfare has been described by Daniel Abbot as a war of "information and perception". There is no widely agreed upon definition of fifth-generation warfare, and it has been rejected by some scholars, including William S. Lind, who was one of the original theorists of fourth-generation warfare.

The Third Wave was an experimental social movement created by California high school history teacher Ron Jones in 1967 to explain how the German population could accept the actions of the Nazi regime during the Second World War. While he taught his students about Nazi Germany during his "Contemporary World History" class, Jones found it difficult to explain how the German people could accept the actions of the Nazis, and decided to create a social movement as a demonstration of the appeal of fascism. Over the course of five days, Jones – a member of the SDS, Cubberley United Student Movement sponsor and Black Panthers supporter – conducted a series of exercises in his classroom emphasizing discipline and community, intended to model certain characteristics of the Nazi movement. As the movement grew outside his class and began to number in the hundreds, Jones began to feel that the movement had spiraled out of control. He convinced the students to attend a rally where he claimed that the classroom project was part of a nationwide movement, and that the announcement of a Third Wave presidential candidate would be televised. Upon their arrival, the students were presented with a blank channel. Jones told his students of the true nature of the movement as an experiment in fascism, and presented to them a short film discussing the actions of Nazi Germany.

🔗 History 🔗 Ancient Near East 🔗 Malta 🔗 Phoenicia

The Cippi of Melqart are a pair of Phoenician marble cippi that were unearthed in Malta under undocumented circumstances and dated to the 2nd century BC. These are votive offerings to the god Melqart, and are inscribed in two languages, Ancient Greek and Phoenician, and in the two corresponding scripts, the Greek and the Phoenician alphabet. They were discovered in the late 17th century, and the identification of their inscription in a letter dated 1694 made them the first Phoenician writing to be identified and published in modern times. Because they present essentially the same text (with some minor differences), the cippi provided the key to the modern understanding of the Phoenician language. In 1758, the French scholar Jean-Jacques Barthélémy relied on their inscription, which used 17 of the 22 letters of the Phoenician alphabet, to decipher the unknown language.

The tradition that the cippi were found in Marsaxlokk was only inferred by their dedication to Heracles, whose temple in Malta had long been identified with the remains at Tas-Silġ. The Grand Master of the Order of the Knights Hospitaller, Fra Emmanuel de Rohan-Polduc, presented one of the cippi to the Académie des Inscriptions et Belles-Lettres in 1782. This cippus is currently in the Louvre Museum in Paris, while the other rests in the National Museum of Archaeology in Valletta, Malta. The inscription is known as KAI 47.

A pencil ( ) is a writing or drawing implement with a solid pigment core in a protective casing that reduces the risk of core breakage, and keeps it from marking the user's hand.

Pencils create marks by physical abrasion, leaving a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which dispense liquid or gel ink onto the marked surface.

Most pencil cores are made of graphite powder mixed with a clay binder. Graphite pencils (traditionally known as "lead pencils") produce grey or black marks that are easily erased, but otherwise resistant to moisture, most chemicals, ultraviolet radiation and natural aging. Other types of pencil cores, such as those of charcoal, are mainly used for drawing and sketching. Coloured pencils are sometimes used by teachers or editors to correct submitted texts, but are typically regarded as art supplies, especially those with cores made from wax-based binders that tend to smear when erasers are applied to them. Grease pencils have a softer, oily core that can leave marks on smooth surfaces such as glass or porcelain.

The most common pencil casing is thin wood, usually hexagonal in section but sometimes cylindrical or triangular, permanently bonded to the core. Casings may be of other materials, such as plastic or paper. To use the pencil, the casing must be carved or peeled off to expose the working end of the core as a sharp point. Mechanical pencils have more elaborate casings which are not bonded to the core; instead, they support separate, mobile pigment cores that can be extended or retracted (usually through the casing's tip) as needed. These casings can be reloaded with new cores (usually graphite) as the previous ones are exhausted.

MISRA C is a set of software development guidelines for the C programming language developed by The MISRA Consortium. Its aims are to facilitate code safety, security, portability and reliability in the context of embedded systems, specifically those systems programmed in ISO C / C90 / C99.

There is also a set of guidelines for MISRA C++ not covered by this article.

🔗 Australia 🔗 Organizations 🔗 Men's Issues

Men's sheds or community sheds are non-profit local organisations that provide a space for craftwork and social interaction. The movement originated in Australia around the 1980s as a way to improve the health and wellbeing of older men. However some have expanded their remit to anyone regardless of age or gender, and have similar aims and functions to hackerspaces. There are over 900 located across Australia, with thousands of active members. Men's sheds can also be found in the United Kingdom, Ireland, United States, Canada, Finland, Estonia, New Zealand and Greece.

The slogan for men's sheds is "Shoulder To Shoulder", shortened from "Men don't talk face to face, they talk shoulder to shoulder", adopted after the 2008 Australian Men's Shed Association (AMSA) conference. The users of men's sheds are known as "shedders". In 2014, Professor Barry Golding coined the term "shedagogy" to describe "a distinctive, new way of acknowledging, describing and addressing the way some men prefer to learn informally in shed-like spaces mainly with other men." Sheds as a venue for mentoring other men and Inter-generational mentoring is a growing outcome. Academics are using men's sheds as a research venue and research partner in exploring men's health and social needs.

The Hinterkaifeck murders occurred on the evening of 31 March 1922, when six inhabitants of a small Bavarian farmstead, located approximately 70 kilometres (43 mi) north of Munich, Germany, were murdered by an unknown assailant. The six victims were Andreas Gruber (aged 63), his wife Cäzilia Gruber (aged 72), their widowed daughter Viktoria Gabriel (aged 35), Viktoria's children, Cäzilia (aged 7) and Josef (aged 2), and the maid, Maria Baumgartner (aged 44). They were all found struck dead with a mattock, also known as a "grub axe". The perpetrator(s) lived with the six corpses of their victims for three days. The murders are considered one of the most gruesome and puzzling unsolved crimes in German history.

Four of the dead bodies were found stacked up in the barn, the victims having been lured there, one by one. Prior to the incident, the family and their former maid reported hearing strange noises coming from the attic, which led to that maid leaving. The case remains unsolved to this day.

🔗 Spaceflight

A diffractive solar sail, or diffractive lightsail, is a type of solar sail which relies on diffraction instead of reflection for its propulsion. Current diffractive sail designs use thin metamaterial films, containing micrometer-size gratings based on polarization or subwavelength refractive structures, causing light to spread out (i.e. diffract) and thereby exert radiation pressure when it passes through them.
