I always forget what kinds of crazy things you can do with Ruby's blocks and their parameters, so here's a little write-up on them. I regularly forget things I've learned (must be an age thing), and I found that not even books on the Ruby language fully cover all the gory details on block (and method) parameters. So consider this my personal reference of crazy Ruby block syntax features for future use.

As you might know, yesterday morning we had Monday talks at the office! Oriol talked about Object Oriented Nirvana , inspired by an old post about how to improve Object Oriented skills by using certain constraints while you're coding.

Over the years, I've saved the Ruby techniques that have surprised other Rubyists I know. Now past 100, I'm making an e-book of them! It'll be free in all forms, except on the Kindle where it'll be just a few bucks (I want to see if cheap, fun programming Kindle books can work.) To start, I've picked 24 random "tricks" to show off in the video below. Enjoy! (And remember, this is a bit of frivolity, not an exercise in Ruby best practices ;-))
