Ask HN: Best place online to learn building web apps?

I am sick of having a great idea for a web app, yet no way to execute a simple version to try to get funding or help with it. Can anyone give recommendations on the best entry level language and where I can learn it online? I am thinking Ruby on Rails would be a good place to start.

Thanks in advance.

The Django Book is a great way to start with the Python Framework "Django" - Like Ruby on Rails but in Python (and thus with more awesome) - http://www.djangobook.com/en/2.0/
