给博客添加了代码高亮

使用的是Google Code Prettify

因为这个js是google code用的，所以各种语言支持比较全面（当然主要是因为Golang才用的）

直接用的默认css

所以和博客主题不是很搭

准备有时间自己修改一下（目测这几个月内是不行了）

来一段测试一下：

package main

import (
	"fmt"
	"math/rand"
	"sync/atomic"
	"time"
)

type readOp struct {
	key  int
	resp chan int
}
type writeOp struct {
	key  int
	val  int
	resp chan bool
}

func main() {

	var ops int64

	reads := make(chan *readOp)
	writes := make(chan *writeOp)

	go func() {
		var state = make(map[int]int)
		for {
			select {
			case read := <-reads:
				read.resp <- state[read.key]
			case write := <-writes:
				state[write.key] = write.val
				write.resp <- true
			}
		}
	}()

	for r := 0; r < 100; r++ {
		go func() {
			for {
				read := &readOp{
					key:  rand.Intn(5),
					resp: make(chan int)}
				reads <- read
				<-read.resp
				atomic.AddInt64(&ops, 1)
			}
		}()
	}

	for w := 0; w < 10; w++ {
		go func() {
			for {
				write := &writeOp{
					key:  rand.Intn(5),
					val:  rand.Intn(100),
					resp: make(chan bool)}
				writes <- write
				<-write.resp
				atomic.AddInt64(&ops, 1)
			}
		}()
	}

	time.Sleep(time.Second)

	opsFinal := atomic.LoadInt64(&ops)
	fmt.Println("ops:", opsFinal)
}
