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).

m3u8 Downloading

Open Chrome Developer tools and click the Network tab.
Navigate to the page with the video and get it to start playing.
Filter the list of files to "m3u8".
Find master.m3u8 or index.m3u8 and click on it.
Save the file to disk and look inside it.
If the file contains a single m3u8 master url, copy that one instead.
Run the program m3u8x.
Paste the same m3u8 url in both textboxes (URL and Quality URL) and click "Headers" and set the referral url and user-agent from the request as found in Chrome.

Update 28 July 2019: An updated version of this guide for Ubuntu Server 18.04 LTS is now available. Feel free to check it out.

Update 23 May 2020: This guide is ALREADY OUTDATED and might no longer work with new versions of Ubuntu and VirtualBox. Please consider switching to the updated guide instead. I will no longer respond to the replies to this gist. Thank you.

Mounting VirtualBox shared folders on Ubuntu Server 16.04 LTS

This guide will walk you through steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest. Tested on Ubuntu Server 16.04.3 LTS (Xenial Xerus)

Here's how you could create custom error classes in Node.js using latest ES6 / ES2015 syntax.

I've tried to make it as lean and unobtrusive as possible.

Defining our own base class for errors

errors/AppError.js

Let's migrate a Symfony 2.8 LTS application to Symfony 3 LTS

Handle deprecations

First of all, ensure you don't have any deprecated!

The Symfony documentation explains it well, but let's sum up:

install the phpunit bridge ($ composer require --dev symfony/phpunit-bridge)
also check all your pages using web profiler and be ensure there is no deprecation error handled
found errors and need help about how to fix it ? I did a sort of guide.

Set up cmder to use msysgit / bash by default

Install cmder_mini (msysgit is already installed, so no need for full version)
In Cmder, open settings: Win + Alt + P
Under Startup > Tasks, add a task called {bash} with the following settings:
- Task parameters (set icon):
  - For Cmder icon: /icon "%CMDER_ROOT%\cmder.exe"
  - For Git icon: /icon "C:\Program Files (x86)\Git\etc\git.ico"
- Commands (open Git's bash shell):
"C:\Program Files (x86)\Git\bin\sh.exe" -l -new_console:d:%USERPROFILE%
