script for extracting the turbulence around a photo of a building.

% correct the rotation
I2 = imrotate(I1, -90);
% crop it to the area of interest
I3 = imcrop(I2,[378.5 0.5 948 814]);
% focus on an roi to isolate just the sky from the building...

This Rack middleware for Rails3 lets you see a call-trace of the lines of ruby code in your application invoked during a single request. Only code within your app is considered (i.e. in the /app folder). This expands on my previous attempt (https://gist.github.com/3077744). Example of output in comments below.
require 'singleton'
# outputs a colored call-trace graph to the Rails logger of the lines of ruby code
# invoked during a single request.
#
# Example:
#
# 1) Make sure this file is loaded in an initializer
#
# 2) Add the following to your application.rb in Rails3:

a set of diophantine equations relating father and son...
# Interesting relationships:
# Say the father's age is 72 and the son's age is 40.
# The father was born in 1940 and the son in 1972.
# Isn't that curious?
# In english, the dad's age is the current year minus the dad's birth year,
# the right-most 2 digits of the dad's birth year is the son's age,
