Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

	##
	# sudo chmod 775 /usr/local/bin/checkwifi.sh
	# crontab -e
	# /5 * * * /usr/bin/sudo -H /usr/local/bin/checkwifi.sh >> /dev/null 2>&1
	##

	## reboot on network failure
	ping -c4 192.168.1.1 > /dev/null

	if [ $? != 0 ]

	import (
	"crypto/md5"
	"encoding/hex"
	)

	func GetMD5Hash(text string) string {
	hasher := md5.New()
	hasher.Write([]byte(text))
	return hex.EncodeToString(hasher.Sum(nil))
	}

	#!/bin/bash

	CUR_DIR=$(pwd)

	echo "\n\Pulling in latest changes for all module...\n"

	for i in $(find . -name ".git" \| cut -c 3-); do
	echo "";
	echo "current directory"+$i;
	cd "$i";

	-- list all go deps

	`go list -e -json -compiled .`
