Because I switch between ColdFusion and Ruby on a weekly basis, when I work on ColdFusion I sometimes miss some of the features that I have in Ruby. Like having a hash return a nil when a key doesn't exist, rather than getting an error when a key...

I was quite confused when I saw lines like this in controllers that I was working on:
class SessionController < ApplicationController

sign_in user
redirect_to user
else
redirect_to sign_in_path
end
end
end
Sign in user? Is it that easy? Do I just type what I want in plain text and the computer will know what I’m talking about? Well, no, of course not...but as someone new to the system, these sorts of conventions can be really confusing.

Last night I wrote this fun code to see if I could display a Mandelbrot fractal in my terminal. It was easier than I thought, thanks to some pseudo-code on the Mandelbrot Set Wikipedia page, although tracking down the proper...
