Go's Pseudo-random number generator isn't very pseudo. In fact, it's not random at all.

package main
import (
	"fmt"
	"time"
	"math/rand"
)
var out = make(chan string, 3)
var done = make(chan bool)
func f(c chan<- string) {
    for i := 0; i<10 ; i++ {
        c<-(time.Millisecond * time.Duration(rand.Intn(1000))).String()
    }
    time.Sleep(time.Millisecond * 10)
    done<-true
}
func printer(c <-chan string) {
    for {fmt.Println(<- c)}
}
//initialize the random seed to the current time
func init(){
    rand.Seed(time.Now().UnixNano())
}
func main() {
    go f(out)
    go printer(out)
    <-done
}
