So, linode bailed (http://yfrog.com/kkrk4p) while I was in the middle of working on the band website (http://www.thebonscotts.com)

That annoyed me somewhat.

Here's what I did to move it off linode in under one hour (except for DNS TTLs, obvs):

• logged in to my (already extant) AWS account
• created an elastic IP

How to calculate an hourly rate.

Hi,

I've been watching job boards for Ruby related contracts lately and have noticed some low rates being offered with high expectations. It's happening frequently enough that I wanted to post my understanding of how to calculate an hourly rate. Setting reasonable standards of pay for the appropriate level of expertise is vital. There's a lot to say on the matter, so I've tried to be brief.

For some reason it's very easy for software developers to match their experience and knowledge to a full-time rate, but for contracting there is less awareness.

The difference between full-time employment and self employment.
