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.

How to setup your VMWare Fusion images to use static IP addresses on Mac OS X

At Crush + Lovely, we use Railsmachine's Moonshine to automate the configuration of our servers. When writing our deployment recipes, VMWare Fusion's ability to take snapshots and rollback to these snapshots is a huge timesaver because it takes just seconds to roll a server image to it's original state.

When you're just configuring a single server, having a static IP address for your server image isn't too important, but when you're configuring multi-server setups, it can be useful to duplicate a number of server images and give each a static IP address so you can consistently deploy to them. While not documented well at all, it turns out that this is relatively easy to accomplish in four simple steps.

1. Determine the MAC address of your guest machine

Let's say you have a guest machine with the name ubuntu-lucid-lynx-base a

# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.
