Install EPEL Repository on CENTOS

Just putting this here:

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

Install latest Python on Centos

This script will download, compile and install a newer version of Python on CENTOS / RedHat 5.* in a way which respects the underlying Python 2.4 used by Yum etc.

Based on http://www.venkysblog.com/install-python264-modwsgi-and-django-on-cento and http://binarysushi.com/blog/2009/aug/19/CentOS-5-3-python-2-5-virtualevn-mod-wsgi-and-mod-rpaf/.

ZSH and .zshrc

Apparently ZSH is quite good so I'm going to try it out. On most Linux distros this is going to be installed anyway, but the steps are:

yum install zsh
chsh -s /bin/zsh


Here are some links about customizing it:

Unicode

Seems like a good article, this has always seemed a little mysterious.

I especially found the part about http-equiv content type useful. It had always bothered me how you could specify the character encoding after the start of the file. As it turns out it is a compromise and I am not the only person who had wondered about it.
