Why I Like Go

I visited with PagerDuty yesterday for a little Friday beer and pizza. While there I got started talking about Go. I was asked by Alex, their CEO, why I liked it. Several other people have asked me the same question recently, so I figured it was worth posting.

Goroutines

The first 1/2 of Go's concurrency story. Lightweight, concurrent function execution. You can spawn tons of these if needed and the Go runtime multiplexes them onto the configured number of CPUs/Threads as needed.

	printf "\e[32mRemoving merged branches:\n\033[0m"
	git branch --merged master \| grep -v master

	read -p "Are you sure? " -n 1
	echo "\n"
	if [[ ! $REPLY =~ ^[Yy]$ ]]
	then
	exit 1

	package math

	import (
	"errors"
	m "math"
	)

	// Finds the minimum value in a slice of numbers
	func Min(xs []float64) (float64, error) {
	if len(xs) == 0 {
