The Appian Way (Latin and Italian: Via Appia) is one of the earliest and strategically most important Roman roads of the ancient republic. It connected Rome to Brindisi, in southeast Italy. Its importance is indicated by its common name, recorded by Statius, of Appia longarum... regina viarum ("the Appian Way, the queen of the long roads").

The road is named after Appius Claudius Caecus, the Roman censor who began and completed the first section as a military road to the south in 312 BC during the Samnite Wars.

🔗 Video games

In video games, grinding is performing repetitive tasks, usually for a gameplay advantage or loot but in some cases for purely aesthetic or cosmetic benefits. Many video games use different tactics to implement, or reduce, the amount of grinding in the gameplay. The general use of grinding is for "experience points", or to improve a character's level. In addition, the behavior is sometimes referred to as pushing the bar (leveling up), farming (acquiring loot repeatedly from one source), or catassing.

🔗 Computing

Amoeba is a distributed operating system developed by Andrew S. Tanenbaum and others at the Vrije Universiteit Amsterdam. The aim of the Amoeba project was to build a timesharing system that makes an entire network of computers appear to the user as a single machine. Development at the Vrije Universiteit was stopped: the source code of the latest version (5.3) was last modified on 30 July 1996.

The Python programming language was originally developed for this platform.

Patentleft (also patent left, copyleft-style patent license or open patent) is the practice of licensing patents (especially biological patents) for royalty-free use, on the condition that adopters license related improvements they develop under the same terms. Copyleft-style licensors seek "continuous growth of a universally accessible technology commons" from which they, and others, will benefit.

Patentleft is analogous to copyleft, a license which allows distribution of a copyrighted work and derived works, but only under the same or equivalent terms.

🔗 Mathematics

Wang tiles (or Wang dominoes), first proposed by mathematician, logician, and philosopher Hao Wang in 1961, are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them.

The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern.

In multi-objective optimization, the Pareto front (also called Pareto frontier or Pareto curve) is the set of all Pareto efficient solutions. The concept is widely used in engineering.^{: 111–148} It allows the designer to restrict attention to the set of efficient choices, and to make tradeoffs within this set, rather than considering the full range of every parameter.^{: 63–65 : 399–412}

Hachikō (ハチ公, November 10, 1923 – March 8, 1935) was a Japanese Akita dog remembered for his remarkable loyalty to his owner, Hidesaburō Ueno, for whom he continued to wait for over nine years following Ueno's death.

Hachikō was born on November 10, 1923, at a farm near the city of Ōdate, Akita Prefecture. In 1924, Hidesaburō Ueno, a professor at the Tokyo Imperial University, brought him to live in Shibuya, Tokyo, as his pet. Hachikō would meet Ueno at Shibuya Station every day after his commute home. This continued until May 21, 1925, when Ueno died of a cerebral hemorrhage while at work. From then until his death on March 8, 1935, Hachikō would return to Shibuya Station every day to await Ueno's return.

During his lifetime, the dog was held up in Japanese culture as an example of loyalty and fidelity. Well after his death, he continues to be remembered in worldwide popular culture, with statues, movies, books, and appearances in various media. Hachikō is known in Japanese as chūken Hachikō (忠犬ハチ公) "faithful dog Hachikō", hachi meaning "eight" and the suffix -kō indicating affection.

Tired mountain syndrome is a condition in which underground nuclear testing fractures and weakens rock, increasing permeability and the risk of release of radionuclides and radioactive contamination of the environment. Locations said to have undergone the syndrome include the French Polynesian island of Moruroa, Rainier Mesa in the United States, the Dnepr 1 nuclear test site on the Kola Peninsula in Russia, possibly Mount Lazarev in the Novaya Zemlya Test Site in Russia, and Mount Mantap in North Korea.
