Found Work

I have not been updating lately, but maybe that will change. Back in March I started a new job. Getting back on top of things has taken a while, but within the bounds of protecting the privacy of my new employer, I'll have to say you will not be reading much about my new job here.

I think there is plenty else that I can talk about that will be fun to blog about.
