Architecture, Backup and Recovery

I’m proud to say that I’ve only lost one job in my life. I was a grocery store bagger when the store came under pressure to increase their percentage of minority workers. They laid off all of the Caucasian baggers, but I’m not bitter. I actually loved bagging groceries, and if I hadn’t been laid…
