Running two Firefox profiles at the same time

It's helpful to have multiple FF profiles as you experiment with plugins and try out various options. I find it useful to have one profile where I disable images (cutting down distrations and have perceived faster page load times). You may have noticed that FF normally doesn't allow to run multiple profiles at the same time.

This can be averted using the following command:
firefox -P Default -no-remote

Familiar typing in Putty

I guess, almost everyone, resorts to Putty for connecting to production servers running linux from their windows desktop. I have long hated Putty's hot key interpretation. I miss my bash hotkeys Alt-B, Alt-F, Ctrl-K, etc. (even Home and End) in the Putty realm. Everything that I try gives the annoying '~'. Much recently, I stumbled upon:
http://superuser.com/questions/94436/how-to-configure-putty-so-that-home-end-pgup-pgdn-work-properly-in-bash

And my Putty frustration vanished instantly. In a nutshell, you just gotta set the terminal-type String under the Connection --> Data tab from “xterm” to “linux”.
