Unmuting Twitch VODs

As you know, Twitch has made a weird decision to mute VODs if it finds copyrighted content in videos.

Here's how to enjoy VODs without this annoying mute feature.

• Install Fiddler (tested on 4.4.9.2 on Windows).
• Enable HTTPS decryption. If you are using Firefox, you will need to do this.
• Rules -> Customize Rules...
• Paste the following code in the OnBeforeResponse method:

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000
