FFmpeg Cheat Sheet for 360º video

Brought to you by Headjack

 
FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

 
Let's start with some basics:

• ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file

Raspberry Pi VPN Router

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to ExpressVPN.

This is adapted from SuperJamie's gist.

Requirements

I used a Raspberry Pi 3 - seems like the extra speed may be useful for running VPN.

Install HomeBrew first

brew update
brew tap caskroom/cask
brew install brew-cask

If you get the error "already installed", follow the instructions to unlink it, then install again:

#!/usr/bin/env ruby

require 'open3'
require 'json'

ffmpeg_bin = '/usr/local/bin/ffmpeg'
target_il  = -24.0
target_lra = +11.0
target_tp  = -2.0
samplerate = '48k'

These instructions will explain how to install tensorflow on mac with cuda enabled GPU suport. I assume you know what tensorflow is and why you would want to have a deep learning framework running on your computer.

Prerequisites

Make sure to update your homebrew formulas

Easy UI Regression Testing with Wraith and TravisCI

Introduction

In the past four years, I've learned the hard way about how painful it can be to try and update a codebase used by a large number of applications. Changes that seem innocent can break a specific use case that wasn't anticipated. Do enough manual regression testing and you will catch the bugs, but it's' costly and time consuming process. When things are costly and time consuming, they usually stop being done.

This is why I focus a lot of my efforts towards build process automation. Computers are fantastic about doing boring, repetitive work and never complaining. If you can get them to do the boring chores for you, you spend more time doing the fun, challenging work.

UI Regression testing is one of those spots where I'm looking for automation scripts to take over. Not only because playing "spot the difference" between your builds is boring, but also because [we're horrible at it](http://en.wikipedia.org/wiki/Chan

# as of rqrcode 10.0 (Feb 2016), it can natively render ANSI making my code irrelevant:

require 'rubygems'
require 'rqrcode'

puts RQRCode::QRCode.new("http://www.example.com/").as_ansi

class Trie
  attr_accessor :word, :trie

    @word = false
  end

  def <<(string)
    node = string.each_char.inject(self) { |node, char| node.trie[char] ||= Trie.new }

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>
