At the time it was python, databases, C, unix and java. A mixture of sys admin and development for online medical records. Part of the reason I left was because I found that I could not cope with how boring my job was. I do not compartmentalize very well. When I returned, I worked for a place that made a music player.
I worked with some of the same guys earlier in my career. However, it really was simple serendipity - they happened to be working down the street from where I was living and I ran into them.
i'm curious because i wonder what fields it's easy to find work in again after a year off.
