Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.

Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)

  IMPORTANT: Requires this version of jquery 
             until 1.3.3 comes out http://gist.github.com/186325

  ALSO:      This is very dirty still and has not been 
             abstracted for use. It is just solving our immediate problems.

  Use cases that must pass (and should be tested someday):
    * Clicking on links updates layout
    * Click around a bit and then use back/forward buttons
