Being able to ssh <build farm> && tmux attach to reconnect to your development environment is powerful, especially when your testing environment consists of connecting to a number of different systems at once.

Examle, a persistent tmux session with splits on a big monitor, Vim/Editor in one pane with live-UT results in another and documentation/misc details (scratch?) in another kicked off as I save.

Once kiddo's go to bed I can simply 'tmux attach' from any machine with access and be up and running.

I use IDEs and Vim, but there is clear value to working completely inside the terminal.
