The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan [9] [10] ( c. 4th century BCE), [11] referring to a historical event of 548BCE. It is also mentioned in Book XVII of the Analects of Confucius [11] and in two books written by Mencius [10] [79] ( c. 3rd century BCE). [11] In all of these works, the game is referred to as yì ( 弈). Today, in China, it is known as weiqi ( simplified Chinese: 围棋; traditional Chinese: 圍棋; pinyin: wéiqí ⓘ; Wade–Giles: wei ch'i), lit. 'encirclement board game'. Go programming language is easy to learn and it's one of the most popular programming languages out there right now. The primary concurrency construct is the goroutine, a type of green thread. [91] :280–281 A function call prefixed with the go keyword starts a function in a new goroutine. The language specification does not specify how goroutines should be implemented, but current implementations multiplex a Go process's goroutines onto a smaller set of operating-system threads, similar to the scheduling performed in Erlang. [92] :10 Eventually, the money always runs out. Let’s agree that we’ll stop withdrawing when our fund is down to its last ten dollars, and spend that money on a communal pizza to celebrate or commiserate around. Our benchmark will reflect this: // Spawn off the workers
Go is a statically typed, compiled high-level programming language designed at Google [11] by Robert Griesemer, Rob Pike, and Ken Thompson. [12] It is syntactically similar to C, but also has memory safety, garbage collection, structural typing, [6] and CSP-style concurrency. [13] It is often referred to as Golang because of its former domain name, golang.org, but its proper name is Go. [14]Frequently, the winner of the ko fight does not connect the ko but instead captures one of the chains that constituted their opponent's side of the ko. [51] In some cases, this leads to another ko fight at a neighboring location. The Go language has built-in facilities, as well as library support, for writing concurrent programs. Concurrency refers not only to CPU parallelism, but also to asynchrony: letting slow operations like a database or network read run while the program does other work, as is common in event-based servers. [90] Pike, Rob (October 25, 2012). "Go at Google: Language Design in the Service of Software Engineering". Google, Inc. "There is one important caveat: Go is not purely memory safe in the presence of concurrency." One of the most important skills required for strong tactical play is the ability to read ahead. [65] Reading ahead includes considering available moves to play, the possible responses to each move, and the subsequent possibilities after each of those responses. Some of the strongest players of the game can read up to 40 moves ahead even in complicated positions. [66]
You may have spotted an opportunity to clean things up some more now. Since we have a generic Transact command, we don’t need WithdrawCommand or BalanceCommand anymore. We’ll rewrite them in terms of transactions: func (s *FundServer) Balance() int { On day one the Go team published a collection of Go idioms, [121] and later also collected code review comments, [124] talks, [125] and official blog posts [126] to teach Go style and coding philosophy. Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 4,500 years ago and is believed to be the oldest board game continuously played to the present day. [1] [2] [3] A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go, and over 20 million current players, the majority of whom live in East Asia. [4] We’ll use a channel to send commands to our FundServer. Every benchmark worker will send commands to the channel, but only the server will receive them. In June 2020, a new draft design document [41] was published that would add the necessary syntax to Go for declaring generic functions and types. A code translation tool, go2go, was provided to allow users to try the new syntax, along with a generics-enabled version of the online Go Playground. [42]Other, less expensive woods often used to make quality table boards in both Chinese and Japanese dimensions include Hiba ( Thujopsis dolabrata), Katsura ( Cercidiphyllum japonicum), Kauri ( Agathis), and Shin Kaya (various varieties of spruce, commonly from Alaska, Siberia and China's Yunnan Province). [127] So-called Shin Kaya is a potentially confusing merchant's term: shin means 'new', and thus shin kaya is best translated 'faux kaya', because the woods so described are biologically unrelated to Kaya.

After the end of the Tokugawa shogunate and the Meiji Restoration period, the Go houses slowly disappeared, and in 1924, the Nihon Ki-in (Japanese Go Association) was formed. Top players from this period often played newspaper-sponsored matches of 2–10 games. [113] Of special note are the (Chinese-born) player Go Seigen (Chinese: Wu Qingyuan), who scored 80% in these matches and beat down most of his opponents to inferior handicaps, [114] and Minoru Kitani, who dominated matches in the early 1930s. [115] These two players are also recognized for their groundbreaking work on new opening theory ( Shinfuseki). [116]While the various rulesets agree on the ko rule prohibiting returning the board to an immediately previous position, they deal in different ways with the relatively uncommon situation in which a player might recreate a past position that is further removed. See Rules of Go §Repetition for further information. An interface system in place of virtual inheritance, and type embedding instead of non-virtual inheritance We could have made our commands channel take *pointers* to commands (`chan *TransactionCommand`). Why didn't we? Although the game was developed in China, the establishment of the Four Go houses by Tokugawa Ieyasu at the start of the 17th century shifted the focus of the Go world to Japan. State sponsorship, allowing players to dedicate themselves full-time to study of the game, and fierce competition between individual houses resulted in a significant increase in the level of play. During this period, the best player of his generation was given the prestigious title Meijin (master) and the post of Godokoro (minister of Go). Of special note are the players who were dubbed Kisei (Go Sage). The only three players to receive this honor were Dōsaku, Jōwa and Shūsaku, all of the house Hon'inbō. [112] Hon'inbō Shūsai (left), last head of house Hon'inbō, plays against then-up-and-coming Go Seigen in the game of the century.
