<p>I have three elements consisting of 1 million, 2 million and 3 million ints respectively. I want to insert them to redis such that they all happen concurrently and the total execution time is not greater than the execution time of the 3 million ints. I tried using sync.Waitgroup but it doesn't speed up the execution. Here's...阅读全文

go Go 亦称为 Golang（译注：按照 Rob Pike 说法，语言叫做 Go，Golang 只是官方网站的网址），是由谷歌开发的一个开源的编译型的静态语言。 Golang 的主要关注点是使得高可用性和可扩展性的 Web 应用的开发变得简便容易。（译注：Go 的定位是系统编程语言，只是对 Web 开发支持较好） 既然有很多其他编程语言可以做同样的工作，如 Python，Ruby，Nodejs 等，为什么要选择 Golang 作为服务端编程语言？ 为何选择 Golang 以下是我使用 Go 语言时发现的一些优点： 并发是语言的一部分（译注：并非通过标准库实现），所以编写多线程程序会是一件很容易的事。后续教程将会讨论到，并发是通过 Goroutines 和 channels 机制实现的。 ...阅读全文

之前学过一段时间的python，偶然的情况下接触到go语言。得知高性能，高并发，完美跨平台的优势，决定开始入手go语言学习。 首先，需要下载安装go。 https://golang.google.cn/dl/ 安装完成后，可以用命令查看是否安装成功。 打开终端，输入如下 go version // 查看版本 go env // 查看配置 接下来可以开始我们的第一个程序啦。 编写一个 hello world。需要注意文件名需要为 .go 结尾。 package main func main() { print("hello, world\n") } 运行与编译。 在终端中可直接输入 go run 进行编译运行。 在终端中输入go build 可编译为当前系统的可执行文件。 go run 文件名...阅读全文
<p>The recent posts about multi-stage docker builds produced containers that were still larger than needed.
