If you are Linux newbie or are still unsure about how to setup your Linux box/slice/server, take a serious look at the Slicehost Articles. Other articles include setup of Apache, Nginx, Postfix, MySQL, Ruby on Rails, Capistrano, SSH, Self-signed certificates, Django, etc.
For all the Only Windows guys who read this, these articles are a great way to get your feet wet with Linux. Can’t hurt your pocket book. It’s free. Ubuntu is currently my favorite distribution.
I’ve tweeted about this a number of times.
These articles are phenomenal.
