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. They start with a super small stack that can grow (and shrink) via dynamic allocation (and freeing). They are as simple as go f(x), where f() is a function.

Recently I've been trying to modify the way that I use the word "just" when I'm at work. Merriam Webster offers a few definitions of the word; the one I'm interested in is the one that means "only", "simply", and to a lesser extent "exactly". I've been working on a new project that involves integrating a number of systems, and as I began rolling pieces out I received a lot a questions in the form of "Couldn't you just ...?" These annoyed me at first, but as I thought about it I realized I often asked questions in the same way, so I began to examine the word and the way I use it.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Application-side Interfaces in Go

By moving the interface to the application-side (application.go), you can still set the implementation-specific configuration details when you instantiate your library structs. If the interface was implemented on the library-side then you would need to provide:

type DB interface {
  Get([]byte) ([]byte, error)
  Put([]byte, []byte) error
  CacheSize() int
 SetCacheSize(int)
