ActiveRecord ETL

I created this to help me run benchmarks/comparisons against Universal ID, but it could serve as the foundation for a robust ETL data pipeline... and it's less than 70 LOC right now! 🤯 🚀

It handles the extract and transform parts of an ETL process and supports the following options:

• only - specify which attributes to include

import { Controller } from '@hotwired/stimulus'

export default class extends Controller {
  connect () {
    this.element.addEventListener('change', this.handleChange.bind(this))
  }

  handleChange (event) {
    this.traverseDown(event.target, event.target.checked)

Keyboard-only Mac Cheatsheet

Hi, I'm Lorna and I don't use a mouse. I have had RSI issues since a bad workstation setup at work in 2006. I've tried a number of extra hardware modifications but what works best for me is to use the keyboard and only the keyboard, so I'm in a good position and never reaching for anything else (except my coffee cup!). I rather unwisely took a job which required me to use a mac (I've been a linux user until now and also had the ability to choose my tools carefully) so here is my cheatsheet of the apps, tricks and keyboard shortcuts I'm using, mostly for my own reference. Since keyboard-only use is also great for productivity, you may also find some of these ideas useful, in which case at least something good has come of this :)

Apps List

There's more detail on a few of these apps but here is a quick overview of the tools I've installed and found helpful
