I was hoping people would find those useful! :)

The ruby racer can be a replacement for Node.js but Node doesn't require you to add a gem to your app. The reason you need one of these is so that you can compile Coffeescript to Javascript (and then combine and minify it in the asset pipeline when you deploy). Node is a Javascript runtime that isn't in the browser and therubyracer gem provides one as well.

Thanks Dana! :) I definitely have some more videos like this in mind. Glad you liked it!

Is it actually causing you problems? I know the "stdin: is not a tty" seems to be more of a warning than an actual problem according to this https://github.com/mitchell...

I haven't run this on Windows yet however, so keep me posted if things don't work after finishing the tutorial. This is a very long thread but someone mentions the error and you might find a solution in here: https://github.com/mitchell...

Figaro and the new Rails 4.1 secrets.yml are ways to manage these. This episode is intented to explain what they are so when you run into things like Figaro and secrets.yml you have a better idea of what you're looking at.

Heroku has a config command that lets you view and set environment variables. More info here: https://devcenter.heroku.co...

Glad I could help! :)

Does sudo apt-get update work? It's saying something is wrong with that.

Take a look at this: http://stackoverflow.com/qu...

What did you set for your repo_url?

That's what Bundler is for. Your version of Rails is application specific, so you let Bundler manage it with your app's Gemfile.

If you have multiple versions of ruby, you'll want to set the default (or use rbenv/rvm to switch). For me, I have 1.8.7, 1.9.3, 2.0, and 2.1 installed on my machine. I set 2.1.2 as the default, but certain applications switch back to 1.9 and 1.8.7 for me.

I'd guess you just haven't set the default to 2.1.2 yet and that's what is missing.

If you've already downloaded all the gems and ruby versions, you can work offline but if you need to install anything new, you'll need an internet connection.

Great! Let me know if there's anything I can make more clear for that part.

Should be as simple as adding in the ".com" to the host thing in your production.rb that you added earlier I believe.

Yeah you'll need to run redis-server in production if you use sidekiq.

You can add config.action_mailer.default_url_options = { host: 'yourdomain.com' } to your config/production.rb file. Just change "yourdomain.com" to the domain or IP address you are using.

Well it says: Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true

So you need to set that in your different environment.rb files. Probably forgot to add that in your production.rb

You add them in. Put them under the development section.

It is inside your Rails app, inside the config directory. See this: https://www.evernote.com/sh...

You can just open that file in your favorite text editor and set the username and password keys inside it. I'd recommend using Sublime Text or something similar to do that.
