There are 2 commands to generate the SSH key, one creates a RSA encryption and the other creates a DSA encryption:

RSA:

ssh-keygen -t rsa

DSA:

ssh-keygen -t dsa

Commands to create larger EBS filesystem then came:

First choose your AMI - you should know that.

# check information on you AMI like size of root mount.
ec2-describe-images <ami-xxxxxxxx>

# Start a new server based on the ami with a 30GB size root mount 
ec2-run-instances --key <KEY RING NAME> --block-device-mapping /dev/sda1=:30 <ami-xxxxxxxx>

Decided to get started using RVM on my Mac, unfortunately, right before continuing development on an otherwise sturdy app.

Upon start-up, there were errors in the log starting with


/!\ FAILSAFE /!\ Sat Dec 11 17:17:47 -0600 2010
Status: 500 Internal Server Error

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 screencast 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 then a phone call or screen sharing.
