[kwlug-disc] screen is keen

Screen is pretty amazing. If you use Ubuntu, there's a package 
containing some nice wrappers for screen named "Byobu". I highly 
recommend. Warning: you may never leave the terminal ever again.

I find screen amazing for coding as I can keep code in one split, and 
compiler messages in the other. I hear VIM is capable of building code, 
but I haven't got around to learning that yet, so screen is very handy.

If you appreciate screen, you might appreciate window managers like 
xmonad or ratpoison. No idea if they support multi-user sessions, but 
they embody the simple-yet-powerful (and minimalist) philosophy 
characteristic of screen.

I couldn't imagine sharing control of a session. Multi-user sessions 
don't look that hard to set up:
