/*

A (very) WIP collection of optimized/recommended jQuery plugin patterns
from @addyosmani, @cowboy, @ajpiano and others.

Disclaimer:
-----------------------
Whilst the end-goal of this gist is to provide a list of recommended patterns, this
is still very much a work-in-progress. I am not advocating the use of anything here 
until we've had sufficient time to tweak and weed out what the most useful patterns

from django.db import connection

# If using cursor without "with" -- it must be closed explicitly:
with connection.cursor() as cursor:
    cursor.execute('select column1, column2, column3 from table where aaa=%s', [5])
    for row in cursor.fetchall():
        print row[0], row[1], row[3]

# Better, using a small image since our app has no dependency on Ubuntu
