Do you manage (or plan to) at least one unix/linux server? If you do, and don't use any configuration management tool yet, I'd like to show you Ansible - simple but powerful tool for automating things on remote machines.
Workshop takes 2-3 hours and you'll be able to try stuff on VMs prepared for you - bring your own laptop with your favorite linux distro.
