Ruby on Rails Dave Thomas(not Wendy's Dave Thomas):
The fact that you don't have have any of the options for date formatting in your Programming Ruby is a fucking letdown. Sort of like your book. You treat Ruby like a glorified version of Perl, ignoring most of the closure goodness.
So fuck you. And for good measure, fuck you David Heinemeier Hansson. I hate your fauxhawk and your framework still sucks. The only reason it's been adapted at all is that it sucks less than other action-based frameworks out there.
The date formatting stuff is at the back of Programming Ruby....doh!
