goroutineで複数の値を並列に生成して全部生成できたら結果を返す - はこべにっき ♨
表題のような処理はたいへん良くあって、似たようなものをみなさん書かれていると思う。自分のコードでも何度か出てきたので、ParallelGenerateという関数に抽象化しつつまとめてみたというメモ的エントリーです。 ParallelGenerate ParallelGenerateは値の生成手段の列を受け取って、値を並列に生成し、結果の列を受け取るためのチャンネルを返す、汎用的な関数。 import ( "sync" ) type Generator interface { Generate() (interface{}, error) } func ParallelGenerate(generators []interface{}) chan []interface{} { generated := make(chan interface{}) finish := make(chan b

New Super Fast Droplet Console. Thanks, Golang! | DigitalOcean
**We think Go is awesome! **A year ago we started looking into Go as a potential language to standardize our backend around. Since then we’ve been looking for every excuse to rewrite some of our services in Go. The first publicly visible service we’ve rewritten is our new web console. Using Go, we were able to dramatically decrease load and connection times from seconds to milliseconds. Aside from
On Go's Web Application Ecosystem
Go just had its fourth birthday, and it’s finding a lot of popularity as a systems/operations language. Tools like Packer (from the creator of Vagrant) and Serf are great examples of how Go’s headline features (concurrency, ease-of-deployment) are well-suited to these use-cases. But it’s also finding some life as a web programming language. A big part of this is owed to how great Go’s included net
ffjson: faster JSON serialization for Golang | Paul Querna
ffjson is a project I have been hacking on for making JSON serialization faster in the Go programing language. ffjson works by generating static code for Go’s JSON serialization interfaces. Fast binary serialization frameworks like Cap’n Proto or Protobufs also use this approach of generating code. Because ffjson is serializing to JSON, it will never be as fast as some of these other tools, but it
Go (“golang”) and Android – Dennis Forbes
EDIT: Own an Android device? Check out Gallus on the Play Store. It’s like Instagram brought Hyperlapse to Android, only a lot better. Readers know that I am a fan of Go: The ease with which you can build highly-concurrent apps is an absolute delight. Let me broaden that a bit: The ease with which you can build pretty much any kind of system or console style app, from a web service layer, a utilit
