>If you aren't familiar with tmux(or GNU screen), you owe it to yourself to become familiar. If you are a deveoper/sysop/cli-type it will act as a force multiplier.

I tend to use tmux for persistent sessions when ssh'ing to and fro between my own personal machines, but I've never really delved that deep into it when my work computer is a macbook pro and I simply use iterm2 and splits.

Likewise, over on linux, everyone raves about tiling window managers, but I've never really moved beyond a simple L/R split that's easily achievable in every decent floating wm / de.
