Azure SDK for Go and Azure REST API examples

This document details how to create credentials to use when making Azure REST API calls or when using the Azure SDK for Go.

I created this gist because my Golang app was returning empty results and when using the REST API I would see this error message:

{
    "error": {
        "code": "AuthorizationFailed",
        "message": "The client '3c470957-xxxxxx' with object id '3c470957-xxxxxx' does not have authorization to perform action 'Microsoft.Resources/resources/read' over scope '/subscriptions/3dcd5fea-zzzzzz' or the scope is invalid. If access was recently granted, please refresh your credentials."
 }

Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
Microsoft Windows 7 SP1 as the host OS
A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

Rails 6 + ActionCable + Stimulus example for pushing updates to the view.

This example will show how to push updates to the view for a Model instance that has changed without the user having to refresh the page.

This example focuses more on getting ActionCable working with Stimulus. If you don't already have stimulus setup in your app, here's a great write up on how to set it up: https://medium.com/better-programming/how-to-add-stimulus-js-to-a-rails-6-application-4201837785f9

Example scenario

You have a Scan model with attributes.
You have a ScanController#show action.
A user is viewing a Scan through the show.html.slim|haml|erb view template.

Rails 5 and ActionCable

Assumptions: The application already exists. You have two models article.rb and comment.rb. Articles have two attributes, title and text. Comments have two attributes, text and article_id. See these instructions if you need help getting started.

Routes

Assuming that you are nesting your :comments resources inside of :articles, mount ActionCable and make sure you have a root.

config/routes.rb

Rails.application.routes.draw do

Toggle Wireless Mode

This script will allow switching between managed and monitor mode for a wireless adapter.

Managed mode is the default wireless adapter mode.

Monitor mode allows monitoring all traffic received on a wireless channel and allows packets to be captured without having to associate with an access point.
