Ask HN: Learning Ruby beyond Codeacademy

I've been learning Ruby of late - my background includes some coding, mostly enough-to-get-by Javascript and PHP, but I'm in marketing and not currently any sort of engineer. However, I've got a side project I want to get going and I'd really like to do it myself... at least get it up and running, as much for ego as anything else. So, I'm teaching myself Ruby (at 33 and married, going back to school isn't a particularly feasible idea).

I've gone through quite a bit of the Codeacademy classes, but I'm not sure where else I should be looking. I'm also curious what complementary technologies I should be looking into - Rails, I assume, but should I be digging more into things like cloud server administration? I've set up web servers on AWS, but never anything particularly complicated.

Thanks,
