You're so polyglot and you don't even know it. You may be using Ruby for too much. It's not the holy grail. This talk will pull from my experience at Heroku where I use much more than Ruby everyday; and I'm not just talking JavaScript. Technologies are designed to take on problems of a specific nature. There are those that are great for systems work and those that are not. Some make generating reports a cinch. A few are remarkable at digging through data. Networking can be a nightmare in some. I'll start with a swift but gentle introduction to Ruby's good but not great suits and move us into what to replace them with.
