A version of Django's UserCreationForm that uses email instead of username, with some nifty features. (Maybe not super robust yet, in terms of concurrency...)

from django.contrib.auth.forms import UserCreationForm
class UniqueUserEmailField(forms.EmailField):

An EmailField which only is valid if no User has that email.

The only simple way to do SSH in Python today is to use subprocess + OpenSSH...
#!/usr/bin/python
# All SSH libraries for Python are junk (2011-10-13).
# Too low-level (libssh2), too buggy (paramiko), too complicated
# (both), too poor in features (no use of the agent, for instance)
# Here is the right solution today:
import subprocess
import sys

python jinja2 examples
#!/usr/bin/env/python

# More of a reference of using jinaj2 without actual template files.
# This is great for a simple output transformation to standard out.
#
# Of course you will need to "sudo pip install jinja2" first!
#
# I like to refer to the following to remember how to use jinja2 :)

SSL setup with Nginx + Gunicorn + Django 1.3 or 1.4

Configuring Nginx to serve SSL content is straight forward, once you have your certificate and key ready: server {    listen 443 default ssl;    root /path/to/source;    server_name mydomain;

   ssl_certificate      /path/to/cert;    ssl_certificate_key  /path/to/key;

An example of using Firebase and WordPress together. The idea is to use WP's custom post types and metaboxes to make content management easy, and sync with Firebase so that your websites have access to a real-time JSON feed of your custom data.
<?php
/**
* All custom functions should be defined in this class
* and tied to WP hooks/filters w/in the constructor method
*/
class Custom_Functions {
// Custom metaboxes and fields configuration
