The polyhedral model (also called the polytope method) is a mathematical framework for programs that perform large numbers of operations -- too large to be explicitly enumerated -- thereby requiring a compact representation. Nested loop programs are the typical, but not the only example, and the most common use of the model is for loop nest optimization in program optimization. The polyhedral method treats each loop iteration within nested loops as lattice points inside mathematical objects called polyhedra, performs affine transformations or more general non-affine transformations such as tiling on the polytopes, and then converts the transformed polytopes into equivalent, but optimized (depending on targeted optimization goal), loop nests through polyhedra scanning.

The Inca road system (often spelled Inka road system and known as Qhapaq Ñan meaning "royal road" in Quechua) was the most extensive and advanced transportation system in pre-Columbian South America. It was at least 40,000 kilometres (25,000 mi) long. The construction of the roads required a large expenditure of time and effort.

The network was composed of formal roads carefully planned, engineered, built, marked and maintained; paved where necessary, with stairways to gain elevation, bridges and accessory constructions such as retaining walls, and water drainage system. It was based on two north-south roads: one along the coast and the second and most important inland and up the mountains, both with numerous branches. It can be directly compared with the road network built during the Roman Empire, although the Inka road system was built one thousand years later. The road system allowed for the transfer of information, goods, soldiers and persons, without the use of wheels, within the Tawantinsuyu or Inka Empire throughout a territory with an extension was almost 2,000,000 km² (770,000 sq mi) and inhabited by about 12 million people.

The roads were bordered, at intervals, with buildings to allow the most effective usage: at short distance there were relay stations for chasquis, the running messengers; at a one-day walking interval tambos allowed support to the road users and the flocks of carrying llamas. Administrative centers with warehouses for re-distribution of goods were found along the roads. Towards the boundaries of the Inka Empire and in new conquered areas pukaras (fortresses) were found.

Part of the road network was built by cultures that precede the Inka Empire, notably the Wari culture in the northern central Peru and the Tiwanaku culture in Bolivia. Different organizations such as UNESCO and IUCN have been working to protect the network in collaboration with the governments and communities of the six countries (Colombia, Ecuador, Peru, Bolivia, Chile and Argentina) through which the Great Inka Road passes.

In modern times the roads see heavy use from tourism, such as the Inca Trail to Machu Picchu, well known by trekkers, connecting Ollantaytambo with Machu Picchu.

Hitsuzendō (筆禅道, "way of Zen through brush") is believed by Zen Buddhists to be a method of achieving samādhi (Japanese: 三昧 sanmai), which is a unification with the highest reality. Hitsuzendo refers specifically to a school of Japanese Zen calligraphy to which the rating system of modern calligraphy (well-proportioned and pleasing to the eye) is foreign. Instead, the calligraphy of Hitsuzendo must breathe with the vitality of eternal experience.

"Ceterum censeo Carthaginem esse delendam", or "Ceterum autem censeo Carthaginem esse delendam" (English: "Furthermore, I consider that Carthage must be destroyed"), often abbreviated to "Carthago delenda est" (English: "Carthage must be destroyed"), is a Latin oratorical phrase pronounced by Cato the Censor, a politician of the Roman Republic. The phrase originates from debates held in the Roman Senate prior to the Third Punic War (149–146 BC) between Rome and Carthage, where Cato is said to have used it as the conclusion to all his speeches in order to push for the war.

A 999-year lease, under historic common law, is an essentially permanent lease of property. The lease locations are mainly in Britain, its former colonies, and the Commonwealth.

A former colony, the Republic of Mauritius (The Raphael Fishing Company Ltd v. The State of Mauritius & Anor (Mauritius) [2008] UKPC 43 (30 July 2008)) established legal precedent on 30 July 2008 in respect of a 'permanent lease' on St. Brandon.

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.

Community Memory (CM) was the first public computerized bulletin board system. Established in 1973 in Berkeley, California, it used an SDS 940 timesharing system in San Francisco connected via a 110 baud link to a teleprinter at a record store in Berkeley to let users enter and retrieve messages. Individuals could place messages in the computer and then look through the memory for a specific notice.

While initially conceived as an information and resource sharing network linking a variety of counter-cultural economic, educational, and social organizations with each other and the public, Community Memory was soon generalized to be an information flea market, by providing unmediated, two-way access to message databases through public computer terminals. Once the system became available, the users demonstrated that it was a general communications medium that could be used for art, literature, journalism, commerce, and social chatter.

An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speed through underground pneumatic tubes to a collection station where it is compacted and sealed in containers. When the container is full, it is transported away and emptied. The system helps facilitate separation and recycling of waste.

The process begins with the deposit of trash into intake hatches, called portholes, which may be specialized for waste, recycling, or compost. Portholes are located in public areas and on private property where the owner has opted in. The waste is then pulled through an underground pipeline by air pressure difference created by large industrial fans, in response to porthole sensors that indicate when the trash needs to be emptied and help ensure that only one kind of waste material is travelling through the pipe at a time. The pipelines converge on a central processing facility that uses automated software to direct the waste to the proper container, from there to be trucked to its final location, such as a landfill or composting plant.

The illusory truth effect (also known as the validity effect, truth effect, or the reiteration effect) is the tendency to believe false information to be correct after repeated exposure. This phenomenon was first identified in a 1977 study at Villanova University and Temple University. When truth is assessed, people rely on whether the information is in line with their understanding or if it feels familiar. The first condition is logical, as people compare new information with what they already know to be true. Repetition makes statements easier to process relative to new, unrepeated statements, leading people to believe that the repeated conclusion is more truthful. The illusory truth effect has also been linked to "hindsight bias", in which the recollection of confidence is skewed after the truth has been received.

In a 2015 study, researchers discovered that familiarity can overpower rationality and that repetitively hearing that a certain fact is wrong can affect the hearer's beliefs. Researchers attributed the illusory truth effect's impact on participants who knew the correct answer to begin with, but were persuaded to believe otherwise through the repetition of a falsehood, to "processing fluency".

The illusory truth effect plays a significant role in such fields as election campaigns, advertising, news media, and political propaganda.

100 Years is an upcoming science fiction film written by John Malkovich and directed by Robert Rodriguez. Advertised in 2015 with the tagline "The Movie You Will Never See", it is due to be released on November 18, 2115. The 100 year span matches the time it takes for a bottle of Louis XIII Cognac to be properly aged before its release to consumers. The film stars an international ensemble, with American actor John Malkovich, Taiwanese actress Shuya Chang, and Chilean actor Marko Zaror.

100 Years will apparently be a short film, Rodriguez having stated in a 2019 interview with French YouTuber InThePanda: "I was making several short films for them, and I finished that one first, we shot that one first, I thought that was gonna be a commercial or something. And then I showed them the movie and they said 'Yeah, that's great, that's great. That's the one we lock away.' And I said 'What? That's the one you lock away? What about the other one with the future--' 'No, that's the commercial.' [...] The one that I was most attached to was the one they locked away."
