Last year, when visiting my family back home in Holland, I also stopped by my grand-parents. My grand-father, now 93 years old, had always been a very active man. However, during the presceding couple of months, he'd gone almost completely blind and now spent his days sitting in a chair.

Add go build script to your Git repo

gobuild.sh

#!/bin/bash

Elapsed and execution time display for commands in ZSH

function preexec() {
 timer=$(($(date +%s%0N)/1000000))

For when I need to think deep, debug something, or design
