A Brief Introduction to GNU Screen: How to Make the Command Line Work for You
A brief introduction to GNU Screen. Screen is part of the GNU project, and is an overlooked utility that can make working on the command line much easier. Screen is a terminal multiplexer that allows for disconnecting remote sessions, multiple ways to enhance viewing of your command line sessions, and better ways to capture data from those sessions. Murph will show you how to use all of this, as well as how to install it under several GNU/Linux (and other) operating systems.

Create Your Portable CentOS Homelab in About an Hour
Need to learn about Linux servers? Get a self-contained CentOS lab up and running in no time. What's required: a host computer with virtualization tools installed, a CentOS (or other RedHat-based) ISO file to install, and about an hour. It should interest anyone looking to quickly set up an environment to study Linux, either for an exam like RHCSA/CE or just to learn how it works. The workshop will be interactive, with questions encouraged. If the audience members have a laptop with a VM host installed and a Red-Hat based .ISO file, they can follow along (quickly).
