Other intermediate-advanced ruby/rails websites?

Hi,

I don't know if it's allowed here, to talk about other resources to learn Rails and ruby, but I'm looking for more intermediate-advanced guides and/or screencasts that are up-to-date

I'm really enjoying GoRails but I always want more :p

Absolutely! Two of my favorites are RubyTapas (i'm on the homepage!) and Destroy All Software

Also, for some practice/challenges checkout http://exercism.io/ and http://www.codewars.com/ :)

I've been playing with exercism and it's pretty cool, but I'm really digging codewars to practice up on Ruby. Great share!
