Tutorial on creating a URL shortener
I think it would be fun to build a URL shortener together. Whether it's a Rails app or a Ruby app served by Sinatra. I've seen your URLs from excid3.com and would like to learn how to generate shortened URLs from scratch. There's several gems/apps/3rd-party that does this but it would be fun to roll our own.
It would be cool when the user creates a profile (via devise or etc...) and then it automatically create the short url with a custom domain
Great idea. I built one of these for when I was learning Python and Django. It was a really good learning experience.
