Gangstead's 6-Step Plan to Terraform Happiness

1. Use Terragrunt
   • If you hit a rough edge with Terraform it's probably addressed by Terragrunt
2. Look at plan before proceeding with apply
3. Thou shalt not use someone else's module
   • Look at the module's source and copy/paste the terraform therein

• You can make your TF simpler and you won't have to keep up with the multiple updates per month, with breaking changes, that the module makes.

FORscan is windows only software. You want to run on a Mac. You can download a big windows VirtualBox image (20 GB), run Boot camp, or pay for something like Parallels ($80) or CrossOver ($60, built on Wine).

Instead you can pay with your time and try to get wine running. Problem: wine development for MacOS seems to have died with Catalina (10.15) dropped any support for 32 bit applications. Also every wine setup tutorial you find for a Mac is tightly coupled to the exact version of Mac/Wine/direction of the wind/ shoe size of the author on the day the tutorial was made and will not work for you. With that said here's what it took for me:

Wineskin. Kegworks Sikarugir

Edit 2/13/25 Wineskin appears to have been renamed to Kegworks

Edit 5/18/26 Kegworks is no more, the current successor is Sikarugir

For the 2026 update I am on a new computer with an Apple silicon chip so had to start from scratch. Imagine my surprise when there's yet another wine wrapper project. This worked for me

## Happy path
# Create a new branch to put your code on
git checkout -b my-new-branch

# Add all your changed files to a commit (will not start tracking new files)
git commit -am "description of my new changes"

# Push your new branch to github.  Then go to github to make a PR
git push -u origin my-new-branch

// Print report very similar to iam users home https://console.aws.amazon.com/iam/home
// But output is in a more easily digestable format (hint: it goes in a spreadsheet)
// 0a. Make sure you have aws cli 2.0 installed and configured
// 0b. `npm install` there should be a package.json with this, but you need lodash, moment, bluebird
// 1. Usage: `node list-users.js`

const exec = require("child_process").exec;
const _ = require("lodash");
const B = require("bluebird");
const moment = require("moment");

Rapture Art of One-liner - Jon Pretty @propensive

rapture.io -collection of libraries for scala

jawn json parser. Quicker than Jackson, and I guess Jackson must normally be considered the quickest.

My thoughts: Awesome talk. Look into rapture, looks useful. Jon is smart.
