I know I'm just nitpicking, but the grammar in the title of the video ("_Whats_ the best way to learn coding?") kills my confidence. Admittedly that isn't indicative of the quality of the product but it's something best avoided.

I spend my summer teaching high school students to code, but I doubt this resource would help at all. To be honest, I'm not sure what the target audience is for this. The tutorial assumes knowledge of Unix (otherwise you're copying commands such as mv, cd, touch, ...) without explanation, meaning it's not necessarily about coding anymore. Yes, knowledge of the Unix command line is important, but that complexity should either be approached explicitly or hidden away, especially with a tag line "the best way to learn coding". Coding is quite independent of the OS you're using.

I'd also question using RoR as "the best way to learn coding". This is nothing against the framework, simply the complexity and the amount that's magically set up for you defeats or complicates the learning process. If they really want to go with that tag line, I'd be more specific -- something like "the best way to learn RoR/webapp coding".

There's also a lack of information on the CodeLearn site. Is it a pay service after the beta ends?

I signed up for the site and got the error message below. I really like the idea of what they're doing, but if they're going to be teaching rails, shouldn't they know better than to show all that information to users?

ActiveRecord::StatementInvalid in Devise::RegistrationsController#create SQLite3::BusyException: database is locked: commit transaction

Rails.root: /home/ubuntu/codelearn

This is typically a sign of having the SQLite DB open in a DB browser such as SQLite DB Browser.

I do agree with you on this point though. Hide this type of information behind a user-friendly error page.

agree with you on the fact that this needs to be abstracted. however, i guess its their pre release beta version, so work can be expected.
