  # Class: Vash (Ruby Volatile Hash)
  # Hash that returns values only for a short time.  This is useful as a cache
  # where I/O is involved.  The primary goal of this object is to reduce I/O 
  # access and due to the nature of I/O being slower then memory, you should also
  # see a gain in quicker response times.
  #
  # For example, if Person.first found the first person from the database & cache 
  # was an instance of Vash then the following would only contact the database for
  # the first iteration:

rklemme

class HexNum < Numeric

  # Create a new instance from an int or String.
  def initialize(val)
    case val
    when String
      @i = parse_string(val)
      @s = val.frozen? ? val : val.dup.freeze
    when Numeric
      @i = val.to_i

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.
