Fred Fish (November 4, 1952 – April 20, 2007) was a computer programmer notable for work on the GNU Debugger and his series of freeware disks for the Amiga.

The Amiga Library Disks – colloquially referred to as Fish Disks (a term coined by Perry Kivolowitz at a Jersey Amiga User Group meeting) – became the first national rallying point, a sort of early postal system. Fish would distribute his disks around the world in time for regional and local user group meetings, which in turn duplicated them for local distribution. Typically, only the cost of materials changed hands. The Fish Disk series ran from 1986 to 1994. In it, one can chart the growing sophistication of Amiga software and see the emergence of many software trends.

The Fish Disks were distributed at computer stores and Amiga enthusiast clubs. Contributors submitted applications and source code and the best of these each month were assembled and released as a diskette. Since the Internet was not yet in popular usage outside military and university circles, this was a primary way for enthusiasts to share work and ideas. He also initiated the "GeekGadgets" project, a GNU standard environment for AmigaOS and BeOS.

Fish worked for Cygnus Solutions in the 1990s before he left for Be Inc. in 1998.

In 1978, he self-published User Survival Guide for TI-58/59 Master Library, which was advertised in enthusiast newsletters covering the TI-59 programmable calculator.

Core War is a 1984 programming game created by D. G. Jones and A. K. Dewdney in which two or more battle programs (called "warriors") compete for control of a virtual computer. These battle programs are written in an abstract assembly language called Redcode.

The Tractatus Logico-Philosophicus (widely abbreviated and cited as TLP) is the only book-length philosophical work by the Austrian philosopher Ludwig Wittgenstein that was published during his lifetime. The project had a broad goal: to identify the relationship between language and reality and to define the limits of science. Wittgenstein wrote the notes for the Tractatus while he was a soldier during World War I and completed it during a military leave in the summer of 1918. It was originally published in German in 1921 as Logisch-Philosophische Abhandlung (Logical-Philosophical Treatise). In 1922 it was published together with an English translation and a Latin title, which was suggested by G. E. Moore as homage to Baruch Spinoza's Tractatus Theologico-Politicus (1670).

The Tractatus is written in an austere and succinct literary style, containing almost no arguments as such, but consists of altogether 525 declarative statements, which are hierarchically numbered.

The Tractatus is recognized by philosophers as one of the most significant philosophical works of the twentieth century and was influential chiefly amongst the logical positivist philosophers of the Vienna Circle, such as Rudolf Carnap and Friedrich Waismann and Bertrand Russell's article "The Philosophy of Logical Atomism".

Wittgenstein's later works, notably the posthumously published Philosophical Investigations, criticised many of his ideas in the Tractatus. There are, however, elements to see a common thread in Wittgenstein's thinking, in spite of those criticisms of the Tractatus in later writings. Indeed, the legendary contrast between ‘early’ and ‘late’ Wittgenstein has been countered by such scholars as Pears (1987) and Hilmy (1987). For example, a relevant, yet neglected aspect of continuity in Wittgenstein’s central issues concerns ‘meaning’ as ‘use’. Connecting his early and later writings on ‘meaning as use’ is his appeal to direct consequences of a term or phrase, reflected e.g. in his speaking of language as a ‘calculus’. These passages are rather crucial to Wittgenstein’s view of ‘meaning as use’, though they have been widely neglected in scholarly literature. The centrality and importance of these passages are corroborated and augmented by renewed examination of Wittgenstein’s Nachlaß, as is done in "From Tractatus to Later Writings and Back - New Implications from the Nachlass" (de Queiroz 2023).

Atomic gardening is a form of mutation breeding where plants are exposed to radioactive sources, typically cobalt-60, in order to generate mutations, some of which have turned out to be useful.

The practice of plant irradiation has resulted in the development of over 2000 new varieties of plants, most of which are now used in agricultural production. One example is the resistance to verticillium wilt of the "Todd's Mitcham" cultivar of peppermint which was produced from a breeding and test program at Brookhaven National Laboratory from the mid-1950s. Additionally, the Rio Star Grapefruit, developed at the Texas A&M Citrus Center in the 1970s, now accounts for over three quarters of the grapefruit produced in Texas.

Greco-Buddhism, or Graeco-Buddhism, is the cultural syncretism between Hellenistic culture and Buddhism, which developed between the 4th century BC and the 5th century AD in Gandhara, in present-day north-western Pakistan and parts of north-east Afghanistan.

It was a cultural consequence of a long chain of interactions begun by Greek forays into the Indian subcontinent from the time of Alexander the Great. A few years after Alexander's death, the Easternmost fringes of the empire of his general Seleucus were lost in a war with the Mauryan Empire, under the reign of Chandragupta Maurya. The Mauryan Emperor Ashoka would convert to Buddhism and spread the religious philosophy throughout his domain, as recorded in the Edicts of Ashoka. This spread to the Greco-Bactrian kingdom, which itself seceded from the Seleucid empire. Within its borders, the Greek fondness for statuary produced the first statues of the Buddha, leading ultimately to the modern tradition.

Following the collapse of the Mauryan Empire, Greco-Buddhism continued to flourish under the Greco-Bactrian Kingdom, Indo-Greek Kingdoms, and Kushan Empire. Mahayana Buddhism was spread from the Gangetic plains in India into Gandhara and then Central Asia during the Mauryan Era, where it became the most prevalent branch of Buddhism in Central Asia. Mahayana Buddhism was later transmitted through the Silk Road into the Han Dynasty during the Kushan era under the reign of Emperor Kanishka. Buddhist tradition details the monk, Majjhantika of Varanasi, was made responsible for spreading Buddhism in the region by Emperor Ashoka.

🔗 Biology 🔗 Palaeontology 🔗 Geology

The Boring Billion, otherwise known as the Mid Proterozoic and Earth's Middle Ages, is the time period between 1.8 and 0.8 billion years ago (Ga) spanning the middle Proterozoic eon, characterized by more or less tectonic stability, climatic stasis, and slow biological evolution. It is bordered by two different oxygenation and glacial events, but the Boring Billion itself had very low oxygen levels and no evidence of glaciation.

The oceans may have been oxygen- and nutrient-poor and sulfidic (euxinia), populated by mainly anoxygenic purple bacteria, a type of chlorophyll-based photosynthetic bacteria which uses hydrogen sulfide (H₂S) instead of water and produces sulfur instead of oxygen. This is known as a Canfield ocean. Such composition may have caused the oceans to be black- and milky-turquoise instead of blue. (By contrast, during the much earlier Purple Earth phase the photosynthesis was retinal-based.)

Despite such adverse conditions, eukaryotes may have evolved around the beginning of the Boring Billion, and adopted several novel adaptations, such as various organelles, multicellularity, and possibly sexual reproduction, and diversified into plants, animals, and fungi at the end of this time interval. Such advances may have been important precursors to the evolution of large, complex life later in the Ediacaran and Phanerozoic. Nonetheless, prokaryotic cyanobacteria were the dominant lifeforms during this time, and likely supported an energy-poor food-web with a small number of protists at the apex level. The land was likely inhabited by prokaryotic cyanobacteria and eukaryotic proto-lichens, the latter more successful here probably due to the greater availability of nutrients than in offshore ocean waters.
