How I Got Node.js Talking on EC2's Port 80
View node-on-ec2-port-80.md

The Problem

Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

The temptingly easy but ultimately wrong solution:

Alter the port the script talks to from 8000 to 80:

}).listen(80);

Finding Twitter User IDs
View finding_twitter_user_id.md

Finding Twitter User IDs

User accounts on Twitter are commonly identified by screen name, which may be changed by operators when they take over an account, or have been sitting on an old account for a long time and want to transition it into malicious use.

User IDs, however, are permanent. There are several services out there that will try to find them for you but it seems like a bad idea to me, since you're alerting them to the fact that there's something interesting about this account. There's also plenty of bad advice that uses many long-since-abandoned Twitter API endpoints.

As of this writing (2018-02-18) you can view source and search for /profile_banners/, which will show something like this:

In the Terminal box, try this:

defaults read com.google.Chrome AppleLanguages

If you see this:

View game.js
/* use strict */
const me = {
// we could potentially set this in game.create from game["_gridWidth"]
// instead of hard-coding the number 24
board: {
height: 24,
width: 24
},
// starting score should be 0

How to turn off TinyMCE in Wordpress
View tinymce_wordpress.txt
In wordpress/wp-includes/class-wp-editor.php, look for the tinymce setting:
public static function parse_settings($editor_id, $settings) {
$set = wp_parse_args( $settings, array(
...
'tinymce' => true, // load TinyMCE, can be used to pass settings directly to TinyMCE using an array()
...
) );
Set it to false and you should be good to go.

Old School:
