Rails (2 & 3) Rake console
A little script (./script/taskrunner) to run a little rake console without having to start up the env everytime, works with environment variables too.
to get it set up, run this from your rails project directory:
curl -o ./script/taskrunner https://raw.github.com/gist/1072723/61b9eb6d458e643b3ea9e679d6501c388f3d3377/taskrunner.rb
chmod +x ./script/taskrunner
./script/taskrunner
