Installation

In case sudo yum install iperf3 doesn't work:

git clone https://github.com/esnet/iperf.git

cd iperf

Run, from within the instance:

curl http://169.254.169.254/latest/meta-data/

It will list available properties. For instance, to get current instance type:

CORS issues when running via Webstorm

Jetbrains had a Chrome extension where you could configure Webstorm to include CORS headers just fine, but it seems to not be working anymore (setting the field and hitting the apply button has no effect - reloading the extension configuration page shows that the field is still empty).

This comment was what helped me, but it was not enough. I reply to that comment with the extra instructions needed. Here's the full conversation in case that page goes down:

Ekaterina Prigara says:

Things I learned while playing with Cordova

use Webstorm to develop your app
deploy via Webstorm (it has a Cordova configuration template)
try your app in Chrome by clicking the Chrome button in Webstorm
configure JetBrains IDE plugin in Chrome to allow for cross-origin requests
your Android app will complain about cross-origin requests as well
you can debug your deployed Android app via Chrome through chrome://inspect
if you're previewing your page in Chrome, you may need to disable web security in order to use fetch() pointing to other domains. See this

Using HTML templates in Javascript

This is the proper way to have HTML templates and clone them in Javascript.

First add the template to your HTML:

<template id="example-template">
    <div class="example">

Plex Media Server on Ubuntu

Install it by following the instructions on the web site.

Troubleshooting Plex not seeing media files

Make sure your directories and files have the right permissions:

find . -type f -exec chmod 644 {} ; find . -type d -exec chmod 755 {} ;

	// @include my-script.js
	// @include "some other script.js"
	/* @include third-script.js */

	setup(); // `setup` is defined in `my-script.js`

	#!/bin/bash
	curl http://169.254.169.254/latest/meta-data/instance-type

	.foo {}

	/* @include other.css */

	.bar {}
