(翻訳)Goでのパイプラインとキャンセル - Qiita
Go's concurrency primitives make it easy to construct streaming data pipelines that make efficient use of I/O and multiple CPUs. This article presents examples of such pipelines, highlights subtleties that arise when operations fail, and introduces techniques for dealing with failures cleanly. There's no formal definition of a pipeline in Go; it's just one of many kinds of concurrent programs. Inf

Go Concurrency Patterns
Go Concurrency Patterns Rob Pike Google Video This talk was presented at Google I/O in June 2012. Watch the talk on YouTube 2 Introduction 3 Concurrency features in Go People seemed fascinated by the concurrency features of Go when the language was first announced. Questions: Why is concurrency supported? What is concurrency, anyway? Where does the idea come from? What is it good for? How do I use
Go言語の気に入ったところ/気に入らなかったところ - はこべにっき ♨
二日間ほど集中してgo言語でコード書いたので、その間に感じたことをまとめてみます。普段はだいたいPerlやJavaScriptでWebアプリケーションを書いています。 まとめの要約 go言語良い Webアプリケーション書くならPerlとかRubyが良い PerlとかRuby書ける人がミドルウェア書くならgo言語良い 気に入ったところ コンパイルエラーが親切 たとえば気楽な気持ちで以下のようなコードを書くと package main import ("fmt"; "net/http"; "log") func main() { resp := http.Get("http://hatenablog.com/") fmt.Println(math.Pi) } 以下のように丁寧に問題箇所を教えてくれます。 ./hoge.go:6: imported and not used: "log" ./h
Big Sky :: Go言語でインタフェースの変更がそれ程問題にならない理由
golang - Go言語における埋め込みによるインタフェースの部分実装パターン - Qiita [キータ] http://qiita.com/tenntenn/items/e04441a40aeb9c31dbaf golang はインタフェースがマッチしているかどうかにより処理を切り分けられる。 package main import "fmt" type Person struct { FirstName string LastName string } func (p *Person) Name() string { return p.FirstName + " " + p.LastName } func main() { person := &Person{"Taro", "Yamada"} fmt.Println(person.Name()) } メソッドを保持しているのであれ

On Go
Updated 2015-09-25: So, about six years later, people are still reading this. I'm not sure how to feel about this; Looking at it now, it's incoherent, badly argued, and a lot of the details are simply wrong. But 1000 hits a month indicate that people still get value out of it. Don't get me wrong; I still think that Go is a terrible language. I now work for a company that does a lot of it, and ever
