πŸ”— Taikyoku Shogi

πŸ”— Chess πŸ”— Japan

Taikyoku shōgi (Japanese: 倧局将棋) lit. "ultimate chess" is the largest known variant of shogi (Japanese chess). The game was created around the mid-16th century (presumably by priests) and is based on earlier large board shogi games. Before the rediscovery of taikyoku shogi in 1997, tai shogi was believed to be the largest playable chess variant ever. It has not been shown that taikyoku shogi was ever widely played. There are only two sets of restored taikyoku shogi pieces and one of them is held at Osaka University of Commerce. One game may be played over several long sessions and require each player to make over a thousand moves.

Because the game was found only recently after centuries of obscurity, it is difficult to say exactly what all the rules were. Several documents describing the game have been found; however, there are differences between them. Many of the pieces appear in other shogi variants but their moves may be different. The board, and likewise the pieces, were made much smaller, making archeological finds difficult to decipher. Research into this game continues for historical and cultural reasons, but also to satisfy the curious and those who wish to play what could be the most challenging chess-like game ever made. More research must be done however. This article focuses on one likely set of rules that can make the game playable in modern times but is by no means canon. These rules may change as more discoveries are made and secrets of the game unlocked.

Further, because of the terse and often incomplete wording of the historical sources for the large shogi variants, except for chu shogi and to a lesser extent dai shogi (which were at some points of time the most prestigious forms of shogi being played), the historical rules of taikyoku shogi are not clear. Different sources often differ significantly in the moves attributed to the pieces, and the degree of contradiction (summarised below with the listing of most known alternative moves) is such that it is likely impossible to reconstruct the "true historical rules" with any degree of certainty, if there ever was such a thing. It is not clear if the game was ever played much historically, as there is no record of any sets having been made.

πŸ”— Hebban Olla Vogala

πŸ”— Middle Ages πŸ”— Middle Ages/History πŸ”— Netherlands

"Hebban olla vogala", sometimes spelled "hebban olla uogala", are the first three words of an 11th-century text fragment written in Old Dutch. The fragment was discovered in 1932 on the flyleaf of a manuscript that was probably made in the abbey of Rochester, Kent and is kept in Oxford. It is usually considered to represent a West Flemish variant of Old Low Franconian.

An often cited poem, it was long believed by many Dutch people to be the only text remaining of Old Dutch. However, experts were already aware of other sources that were then not yet easily accessible. Today, more than 42,000 Old Dutch words and phrases from sources such as the Wachtendonck Psalms and the Leiden Willeram have been discovered, with the oldest definitive source being the Salian Law.

πŸ”— Peppercorn (re: Contract Law)

πŸ”— Law

In legal parlance, a peppercorn is a metaphor for a very small cash payment or other nominal consideration, used to satisfy the requirements for the creation of a legal contract. It is featured in Chappell & Co Ltd v Nestle Co Ltd ([1960] AC 87), which stated that "a peppercorn does not cease to be good consideration if it is established that the promisee does not like pepper and will throw away the corn". However, the cited passage is mere dicta, and not the basis for the decision.

Project Cybersyn was a Chilean project from 1971–1973 during the presidency of Salvador Allende aimed at constructing a distributed decision support system to aid in the management of the national economy. The project consisted of four modules: an economic simulator, custom software to check factory performance, an operations room, and a national network of telex machines that were linked to one mainframe computer.

Project Cybersyn was based on viable system model theory approach to organizational design, and featured innovative technology for its time: it included a network of telex machines (Cybernet) in state-run enterprises that would transmit and receive information with the government in Santiago. Information from the field would be fed into statistical modeling software (Cyberstride) that would monitor production indicators, such as raw material supplies or high rates of worker absenteeism, in "almost" real time, alerting the workers in the first case and, in abnormal situations, if those parameters fell outside acceptable ranges by a very large degree, also the central government. The information would also be input into economic simulation software (CHECO, for CHilean ECOnomic simulator) that the government could use to forecast the possible outcome of economic decisions. Finally, a sophisticated operations room (Opsroom) would provide a space where managers could see relevant economic data, formulate feasible responses to emergencies, and transmit advice and directives to enterprises and factories in alarm situations by using the telex network.

The principal architect of the system was British operations research scientist Stafford Beer, and the system embodied his notions of organisational cybernetics in industrial management. One of its main objectives was to devolve decision-making power within industrial enterprises to their workforce in order to develop self-regulation of factories.

Versions of MCL up to and including 5.1 are proprietary. Version 5.2 has been open sourced.

In 2009 a new different version of MCL has been open sourced: RMCL. RMCL is based on MCL 5.1 and does run under Rosetta on Intel-based Macs.

πŸ”— Esterel – Synchronous programming language for complex, reactive systems

πŸ”— Computing πŸ”— Computer science

Esterel is a synchronous programming language for the development of complex reactive systems. The imperative programming style of Esterel allows the simple expression of parallelism and preemption. As a consequence, it is well suited for control-dominated model designs.

The development of the language started in the early 1980s, and was mainly carried out by a team of Ecole des Mines de Paris and INRIA led by GΓ©rard Berry in France. Current compilers take Esterel programs and generate C code or hardware (RTL) implementations (VHDL or Verilog).

The language is still under development, with several compilers out. The commercial version of Esterel is the development environment Esterel Studio. The company that commercialize it (Synfora) initiated a normalization process with the IEEE in April 2007 however the working group (P1778) dissolved March 2011. The Esterel v7 Reference Manual Version v7 30 – initial IEEE standardization proposal is publicly available.

πŸ”— Thomas of Cana Copper Plates

πŸ”— India πŸ”— India/Kerala πŸ”— India/Indian history

The Thomas of Cana copper plates (Malayalam: Knai Thoma Cheppedu), or Knanaya copper plates, dated variously between 345 C.E. and 811 C.E., are a lost set of copper-plate grants issued by the unidentified Chera/Perumal king of Kerala "Co-qua-rangon" to Syriac Christian merchants led by Knai Thoma (anglicized as Thomas of Cana) in the city of "Makotayar Pattinam" (present day Kodungallur), south India. The royal charters were reportedly engraved in ”Malabar”, Chaldean and Arabic on both sides of two copper plates (joined by a ring). Archbishop Francis Ros notes in his 1604 account M.S. ADD 9853 that the plates were taken to Portugal by the Franciscan Order.

Scholar M.G.S. Narayanan tentatively identifies king β€œCo-qua-rangon” with king Rama Rajasekhara (Co-qua-rangon β†’ Ko Kotai Iraman β†’ Rajadhiraja Rama) of the 9th century Chera Empire.

The Knanaya or the people of Knai Thoma were historically associated with the southern portion of the Chera/Perumal headquarters Kodungallur until in 1524 they were dispersed from the city due to conflict between the Kingdom of Cochin and the Kingdom of Calicut. The plate was cherished by the Knanaya as evidence of their arrival in Kerala under the leadership of Knai Thoma as well as a notation of the historical, economic, and social rights bestowed upon them by the Chera Perumal. The native Christian tradition places the arrival of Thomas of Cana in 345 C.E.

Translations of the existing Kollam Syrian Plates of the 9th century made by the Syrian Christian priest Ittimani in 1601 as well as the French Indologist Abraham Anquetil Duperron in 1758 both note that the one of the plates mentioned a brief of the arrival of Knai Thoma.It is believed that this was a notation of the previous rights bestowed upon the Christians by Cheraman Perumal. The contemporary set however does not mention this paragraph and is believed to be incomplete or a later inscription. Scholar of Early Christian history IstvΓ‘n Percvel theorizes that at one time the Kollam Syrian plates and the Thomas of Cana plates were kept together.
