How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
VPC with NAT, The best of both worlds, AWS services and web.

Make Flashlight work on 10.10.4

Install SIMBL http://culater.net/software/SIMBL/SIMBL.php

Copy Flashlight.osax to ~/Library/ScriptingAdditions/ (b)
Disable Flashlight
Enable Flashlight
Open Script Editor on your Mac (look for "Script Editor In Spotlight") and paste the following code (don't change Snow Leopard for Yosemite)

tell application "Spotlight" to inject SIMBL into Snow Leopard

Default

Powerlevel10k

If you're like me you have a dir like ~/Workspace/Github where all your git repos live. I often find myself making a change in a repo, getting side tracked and ending up in another repo, or off doing something else all together. After a while I end up with several repos with modifications. This script helps me pick up where I left off by checking the status of all my repos, instead of having to check each one individually.

Usage:

git-status [directory]

This will run git status on each repo under the directory specified. If called with no directory provided it will default to the current directory.
