I wrote an email to a developer friend of mine named Josh (great guy & a developer for the past decade!!) and I thought I should put it on my blog. So here you have it:
I've been using Treehouse for all of my code learning. Treehouse has an excellent UI and it puts you on a track to an endpoint(mine is Front End Developer), but it's $25/month.
I started out using Lynda.com, the cool thing about Lynda is you automatically have a free subscription if you have a Los Angeles Public Library Card, I'm sure it will be the same with you in San Diego.
I've also used Code Camp, its free and a great way to learn (I wish I knew about it before Treehouse so I didn't get started on a track and spend $$ ;)
Also, on iOS there's Solo Learn and Lrn. I've completed several full courses on Solo Learn.
Good stuff! Let me know if you have any more questions!
