Creating remote server nicknames with .ssh/config
Using the ~/.ssh/config file is an easy way to give your
remote machines nicknames and reduce the number of keystrokes needed
to login with ssh, rsync,
hg push/pull/clone, access
files via Emacs Tramp
(Transparent Remote (file) Access, Multiple Protocol),
or use any other SSH-based tool.
Here is part of my ~/.ssh/config file. It defines the
nicknames turk, tyran, tuna, and tally for some EC2 servers I've been
working with.
Host turk User root HostName ec2-67-202-21-122.compute-1.amazonaws.com Host tuna User root HostName ec2-75-101-178-62.compute-1.amazonaws.com Host tyran User root HostName ec2-67-202-43-207.compute-1.amazonaws ...Read more...

If you've ever gotten this error, Django's smart_str
function might be able to help. I found this from James Bennett's
article,
Unicode in the real world. He provides a very good explanation
of Python's Unicode and bytestrings, their use in Django, and using
Django's Unicode utilities for working with non-Unicode-friendly
Python libraries. Here are my notes from his article as it applies
to the above error. Much of the wording is directly from James
Bennett's article.
