内容提要

  

    Go编程语言，通常也称为Golang（尽管这种叫法并不对），借助一些大师级开发作品以及最伟大的编程思想的高屋建瓴。着实取得了长足进步。Shopify的首席执行官Tobias  Lutke最近便声称“Go将成为未来的服务器语言”，掷地有声，雄心勃勃。Go程序员的需求量正处于高位，但更有争议的是，Go走上了以前由C和Unix程序员引领的舞台。
    Go语言的成长使其能够实现系统、网络、Web以及云应用。只要熟悉了语法，掌握库的使用并利用其语言特性、速度和效率，你将受益无穷，Go生态学正是因此而闻名。
    你多少已经知道了点Go语言的语法，也编写了一些小项目，而大多数Go程序员都面临着将Go语言技能与生产代码结合的难题。对Go编程的典型介绍往往是浅尝辄止，而本书作者将继续告诉你如何解决这个问题。
    本书提供了Go的概要，介绍了Go的实现，还有专门一章深入解释了并发、系统以及网络编程，这对于现代的原生云开发是必不可少的，读者也将从中受益。

He has written more than 250 technical articles for many publications, including Sys Admin, MacTech, Linux User and Developer,Usenix ;login:, Linux Format, and Linux Journal.
