SSH Tunneling with Firefox

Sometimes it is useful to route traffic through a different machine for testing or development. At work, we have a VPN to a remote facility that we haven't bothered to fix for routing, so the only way to access a certain machine over that VPN is via an SSH tunnel to a machine that is reachable over the VPN. Other times, I have used this technique to test internet-facing requests against sites I am developing. It is pretty easy, and if you don't use firefox regularly, you can treat Firefox as your "Proxy" browser and other browsers can use a normal configuration (Although you can also configure an entire system to use the proxy, other articles exists that discuss this potential).

  1. Open a terminal

How to download m3u8 and ts video movie streams.

m3u8 Downloading

  1. Open Chrome Developer tools and click the Network tab.
  2. Navigate to the page with the video and get it to start playing.

  4. Find master.m3u8 or index.m3u8 and click on it.
  5. Save the file to disk and look inside it.
  6. If the file contains a single m3u8 master url, copy that one instead.
  7. Run the program m3u8x.
  8. 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.

Lumen L5 compatibility helpers. That file should be added on root path of your project... and added to your composer.json
<?php
if(!function_exists('config_path'))
{
/**
* Return the path to config files
* @param null $path
* @return string
*/
function config_path($path=null)

Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions
