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...

Well, no, of course not...but as someone new to the system, these sorts of conventions can be really confusing. If you find yourself in this position, then you are probably coming from another language where class inheritance worked differently from Ruby.  -
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...
