Alto Trek is a computer game, developed by Gene Ball and Rick Rashid for the Xerox Alto while they were graduate students at the University of Rochester during the late 1970s. It is one of the first networked multiplayer games.

🔗 Religion 🔗 Classical Greece and Rome 🔗 Mythology

Glycon (Ancient Greek: Γλύκων Glýkōn, gen: Γλύκωνος Glýkōnos), also spelled Glykon, was an ancient snake god. He had a large and influential cult within the Roman Empire in the 2nd century, with contemporary satirist Lucian providing the primary literary reference to the deity. Lucian claimed Glycon was created in the mid-2nd century by the Greek prophet Alexander of Abonoteichos. Lucian was ill-disposed toward the cult, calling Alexander a false prophet and accusing the whole enterprise of being a hoax: Glycon himself was supposedly a hand puppet.

🔗 Companies 🔗 Computing

The STacy is a portable computer version of the Atari ST.

The computer was originally designed to operate on 12 standard C cell flashlight batteries for portability. When Atari realized how quickly the machine would use up a set of batteries (especially when rechargeable batteries of the time supplied insufficient power compared to the intended alkalines), they simply glued the lid of the battery compartment shut.

The STacy has features similar to the Macintosh Portable, a version of Apple's Macintosh computer which contained a built in keyboard and monitor.

With built-in MIDI, the STacy enjoyed success for running music-sequencer software and as a controller of musical instruments among both amateurs and well-known musicians.

Cairo (stylized as cairo) is an open-source graphics library that provides a vector graphics-based, device-independent API for software developers. It provides primitives for two-dimensional drawing across a number of different back ends. Cairo uses hardware acceleration when available.

Kakure kirishitan (Japanese: 隠れキリシタン, lit. 'hidden Christians') is a modern term for a member of the Catholic Church in Japan that went underground at the start of the Edo period in the early 17th century due to Christianity's repression by the Tokugawa shogunate.

🔗 Physics 🔗 Astronomy

The berserker hypothesis, also known as the deadly probes scenario, is the idea that humans have not yet detected intelligent alien life in the universe because it has been systematically destroyed by a series of lethal Von Neumann probes. The hypothesis is named after the Berserker series of novels (1963-2005) written by Fred Saberhagen.

The hypothesis has no single known proposer, and instead is thought to have emerged over time in response to the Hart–Tipler conjecture, or the idea that an absence of detectable Von Neumann probes is contrapositive evidence that no intelligent life exists outside of the Sun's Solar System. According to the berserker hypothesis, an absence of such probes is not evidence of life's absence, since interstellar probes could "go berserk" and destroy other civilizations, before self-destructing.

In his 1983 paper "The Great Silence", astronomer David Brin summarized the frightening implications of the berserker hypothesis: it is entirely compatible with all the facts and logic of the Fermi paradox, but would mean that there exists no intelligent life left to be discovered. In the worst-case scenario, humanity has already alerted others to its existence, and is next in line to be destroyed.

There is no need to struggle to suppress the elements of the Drake equation in order to explain the Great Silence, nor need we suggest that no [intelligent aliens] anywhere would bear the cost of interstellar travel. It need only happen once for the results of this scenario to become the equilibrium conditions in the Galaxy. We would not have detected extra-terrestrial radio traffic – nor would any [intelligent aliens] have ever settled on Earth – because all were killed shortly after discovering radio.

🔗 Africa 🔗 Africa/Ghana 🔗 Anthroponymy 🔗 Africa/Togo 🔗 Africa/Benin 🔗 Africa/Ivory Coast

The Akan people of Ghana frequently name their children after the day of the week they were born and the order in which they were born. These "day names" have further meanings concerning the soul and character of the person. Middle names have considerably more variety and can refer to their birth order, twin status, or an ancestor's middle name.

This naming tradition is shared throughout West Africa and the African diaspora. During the 18th–19th centuries, enslaved people in the Caribbean from the region that is modern-day Ghana were referred to as Coromantees. Many of the leaders of enslaved people's rebellions had "day names" including Cuffy, Cuffee or Kofi, Cudjoe or Kojo, Quao or Quaw, and Quamina or Kwame/Kwamina.

Most Ghanaians have at least one name from this system, even if they also have an English or Christian name. Notable figures with day names include Ghana's first president Kwame Nkrumah and former United Nations Secretary-General Kofi Annan.

In the official orthography of the Twi language, the Ashanti versions of these names as spoken in Kumasi are as follows. The diacritics on á a̍ à represent high, mid, and low tone (tone does not need to be marked on every vowel), while the diacritic on a̩ is used for vowel harmony and can be ignored. (Diacritics are frequently dropped in any case.) Variants of the names are used in other languages, or may represent different transliteration schemes. The variants mostly consist of different affixes (in Ashanti, kwa- or ko- for men and a- plus -a or -wa for women). For example, among the Fante, the prefixes are kwe-, kwa or ko for men and e-, arespectively. Akan d̩wo or jo(Fante) is pronounced something like English Joe, but there do appear to be two sets of names for those born on Monday.

🔗 Mathematics 🔗 Philosophy 🔗 Philosophy/Logic 🔗 Philosophy/Epistemology

In the philosophy of mathematics, intuitionism, or neointuitionism (opposed to preintuitionism), is an approach where mathematics is considered to be purely the result of the constructive mental activity of humans rather than the discovery of fundamental principles claimed to exist in an objective reality. That is, logic and mathematics are not considered analytic activities wherein deep properties of objective reality are revealed and applied, but are instead considered the application of internally consistent methods used to realize more complex mental constructs, regardless of their possible independent existence in an objective reality.

🔗 Cryptography 🔗 Cryptography/Computer science

Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605. A message is concealed in the presentation of text, rather than its content. Bacon cipher is categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces).
