main.go

package main

import (
	"fmt"
	"net/http"
	"time"
)

func main() {
	http.HandleFunc("/",
		func(w http.ResponseWriter, req *http.Request) {
			w.Write([]byte(fmt.Sprintf("yx is awesome at %s", time.Now())))
		})
	http.ListenAndServe(":80", nil)
}

Fyi, looks like port 80 doesn't work as a port option. Should likely throw an error on gitbao when it is selected. :8080 should work with this example.
