Another tip: use a different colored favicon. Makes identifying browser tabs much easier.

ColorfulTabs in Firefox is great for getting that behavior universally -- different domains get their own hues.

I've long been in the habit of using NEON colors for backgrounds, shell prompts, etc. as a reminder on divergent systems/logins.

When I used KDE, my ssh-to-production script used dcop to change the terminal background colour. (KDE + dcop is great technology. External access to APIs running in other processes. API discovery. Great stuff.)

Whilst gnome-terminal claims to speak dbus, I don't see any functionality exposed which would allow this. Does anyone have any pointers to achieving the same thing?

(Solutions which have occurred to me but which I find unsatisfying: run kterm under gnome, have a launcher script open a new terminal with the desired colour. I'm being picky, but my habits are such that I live in a small number of terminals. I'd like those terminals to change state as I ssh around.)

This is one of those cases where the title of the article really says it all.
