Chad Woolley has put together a helpful blog post called "ruby-debug in 30 seconds (we don't need no stinkin' GUI!)" that covers how to use the ruby-debug command line debugger to debug Ruby applications. Also of interest will be this cheat sheet by the guys over at ErrFree.

Note: This post was drafted before DHH's "The deal with shared hosts" post, but as it covers similar ground, it's worth reading too. DHH's opinion appears to be that shared hosts should put up or shut up, but I disagree and suggest this is something we need to solve as a community.
