一、ABC

• Go by Example
• Popular sites, blogs and tutorials for learning and mastering Go Language
• Learn Go with tests

1.1 Install

• https://go.googlesource.com/go/

tar -C /usr/local/go-$version -xvf go-$version.tar.gz

cd /usr/local/go-$version/src
./all_bash

#compile,build and test

unset GOROOT
unset GOPATH
unset GOAPPATH

export GOROOT=/usr/local/go
export GOPATH=$GOROOT/bin
export GOAPPATH=$GOROOT/bin/bin
export PATH=$PATH:$GOPATH:$GOAPPATH

1.2 Go Version Manage

## 交叉编译

build-linux:
	export CGO_ENABLED=0 && export GOOS=linux && export GOARCH=amd64 && go build
build-wins:
	export CGO_ENABLED=0 && export GOOS=windows && export GOARCH=amd64 && go build
build-solaris:
  export CGO_ENABLED=0 && export GOOS=solaris && export GOARCH=amd64 && go build

## Go supports Solaris 11 on amd64, but not sparc.To build for sparc you need to use gccgo.

## 压缩
go build -ldflags '-w -s'

二、基于 Golang 的应用

2.1 基于Go语言构建RESTful JSON API

2.2 基于Kafka构建事件溯源模式的微服务

讨论如何借助Kafka实现分布式消息管理，使用事件溯源（Event Sourcing）模式实现原子化数据处理，使用CQRS模式（Command-Query Responsibility Segregation ）实现查询职责分离，使用消费者群组解决单点故障问题，理解分布式协调框架Zookeeper的运行机制。整个应用的代码实现使用Go语言描述。

2.3 开源技术架构漫谈：应用程序开发中的日志管理

2.4 网络数据包的捕获、过滤和分析(Packet Capturing)

• What is Packet Capturing
• How can it be used
• What is libpcap
• What is tcpdump & winpcap & snoop
• What is BPF
• What is gopacket

2.5 数据可视化（五）基于网络爬虫制作可视化图表

• 基于网络爬虫的可视化图表:golang,goquery
• 案例：最近十年全国彩票销售变化情况
• 案例：中国科学院院士分布
• 数据可视化技术方案:基于 SVG (D3、Raphael)、基于 Canvas（Echarts）

三、Golang 最佳实践

3.1 Grammar Tips & Simple Demo

• Port Forwarding with Go (zupzup.org)
• A guide to understanding HTTP Request handling and processing in Go

• How did I improve latency by 700% using sync.Pool

The interface is a tool so that you can wire dependencies just by their behaviour, not by how they implement that behaviour.

• Golang Interfaces
