This walkthrough gives you:

Auto-generated controls in the addons panel
Auto-generated controls in your Docs

An introduction to the future of CSF

DOM Performance

How the browser renders the document
- Receives the data (bytes) from the server.
- Parses and converts into tokens (<, TagName, Attribute, AttributeValue, >).
- Turns tokens into nodes.
- Turns nodes into the DOM tree.
Builds CSSOM tree from the css rules.

How to Eyeball Your ‘This’ Context in Javascript

by zach.dev

The early programmer struggles with the Javascript keyword this. But understanding your this context is easier than it seems.

This is all about where a function is invoked. Often, early programmers worry about where the function was declared. Perhaps the function was declared in a specific file or a particular object. Surely this changes it's this!

Nope.

Macbook Pro - Ubuntu Install

Requirements

2 USB drives > 2GB

Pre-Install

Create bootable USB drive

Grab the latest Ubuntu Desktop iso image

	#!/bin/sh
	#
	# File: macos-installer-to-iso.sh
	#
	# Create a bootable ISO image from a macOS installer to install VMware ESXi guests.

	# Debug on: set -x
	set -eux

	{
	"Statement": [
	{
	"Action": [
	"apigateway:*",
	"cloudformation:CancelUpdateStack",
	"cloudformation:ContinueUpdateRollback",
	"cloudformation:CreateChangeSet",
	"cloudformation:CreateStack",
	"cloudformation:CreateUploadBucket",

	// what if this was something browsers just gave us?
	const { vdom } = document;

	// this is same idea as React.createElement
	// or any of the other similar appraoches
	const newVirtualDom = vdom('div', {className: 'some-class'}, [
	vdom('p', null, 'hi')
	])

	// if preferred, someone could easily use JSX and precompile it

	public class Solution {

	public static void main(String[] args) {
	String[] input = { "5", "4+203", "203+4", "20+20+20+4", "444" };
	for (String test : input)
	System.out.printf("%s = %d%n", test, eval(test));
	}

	private static int eval(String input) {
	int sum = 0;

	- Open Automator
	- File -> New -> Service
	- Change "Service Receives" to "files or folders" in "Finder"
	- Add a "Run Shell Script" action
	- Change "Pass input" to "as arguments"
	- Paste the following in the shell script box: open -n -b "com.microsoft.VSCode" --args "$*"
	- Save it as something like "Open in Visual Studio Code"
