Use jQuery to add forms to a django formset
/*
Given the following HTML (a form generated by a django formset), I want to be able to
clone the form elements inside the div#book-form-container, omitting any values
<form action="/books/add/" method="post">
<div id="book-form-wrapper"> <input type="hidden" name="form-TOTAL_FORMS" value="1" id="id_form-TOTAL_FORMS" /> <input type="hidden" name="form-INITIAL_FORMS" value="0" id="id_form-INITIAL_FORMS" />
<div class="book-form-container">
<input type="hidden" name="form-0-id" id="id_form-0-id" />

Use PIL to find a list of colors in an image
import Image
def get_color_list(path_to_image):
"""
Returns a list of tuples for RGB colors: (R, G, B)
This is gonna be slow and memory-intensive. Use at your own risk.
Requires PIL
"""
def _get_color(t): return t[1]

So, converting a float to a decimal yields a TypeError. You first have to convert to a string, then a decimal.
In [14]: Decimal(2.0 * 3.0)

Counting the frequency with which files change in a mercurial repo
# Step 1: Create a style for the output of "hg log"
# See: http://hgbook.red-bean.com/read/customizing-the-output-of-mercurial.html
# I put this in: ~/.hg/templates/fileonly
changeset = '{files}'
file = '{file}\n'
# Step 2: Use the above style and sort/count your output
hg log --style ~/.hg/templates/fileonly --date="2011-01-01 to 2011-04-01" | sort | uniq -c | sort -r
