Python gist to take a complicated nested object and grab a list of numbers from it.
import re
parser = re.compile('(?:[0-9\.]+)')
lambda x: [float(item) for item in parser.findall(repr(x))]

Created July 30, 2013 23:49
Takes a LaTeX *.aux file as its first argument. Outputs a sorted, unique list of all citekeys from the original document. Useful for e.g., copying formatted bibliographic entries to a new document manually. Written when I was taking Chapter 5 of my PhD thesis and turning it into a paper.

< $1 grep \\citation | cut -c 10- | sed -e "s/[{},]/\n/g" | sed -e "/^$/d" | sort -u

Common reducer object. This is a subclass of dict that may be particularly useful when accumulating results on remote workers in a parallel execution context, then doing reduce operations on these results.
class CommonReducer(dict):
'''
Object based on 'dict' that implements the binary addition (obj1 + obj1) and
accumulation (obj += obj2). These operations pass through to the entries in
the commonReducer.
Instances of commonReducer are also callable, with the syntax:
cr(key, value)
this is equivalent to cr += {key: value}.
