This is a quick tutorial explaining how to get a static website hosted on Heroku.

Why do this?

Heroku hosts apps on the internet, not static websites. To get it to run your static portfolio, personal blog, etc., you need to trick Heroku into thinking your website is a PHP app. This 6-step tutorial will teach you how.

Rails Generating & Scaffolding

Rails' use of strict naming conventions means a lot of core code SHOULD be in the same format whoever writes it? It could be written by a friend, colleague or a computer... it shouldn't matter because the same Rails rules apply to everyone.

This means that Rails can actually do some tasks for you! It can actually build things and write code on your behalf...

Coming from another language like PHP, this can seem like magic.
