_{This is a response for one of our apprentices who wanted to learn more about how structs work.}

TL;DR

Part of this is a response and part of it a challenge. If you are only interested in the challenge clone the repo and run rake (more detailed instructions here).

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
