Drop and recreate test database

I would recommend dropping your test database, then re-create it and migrate:

bundle exec rake db:drop RAILS_ENV=test
bundle exec rake db:create RAILS_ENV=test
bundle exec rake db:schema:load RAILS_ENV=test

Shorter:

Creating a valid email address from a name and email, using the Ruby Mail library. Used to prevent invalid headers.

If you are taking user input for name and email, then unless you very carefully validate or escape the name and email, you can end up with an invalid From header by simply concatenating strings. Here is a safe way:

require 'mail'
address = Mail::Address.new email # ex: "john@example.com"
address.display_name = name # ex: "John Doe"
# Set the From or Reply-To header to the following:
address.format # returns "John Doe <john@example.com>"

The introduction to Reactive Programming you've been missing

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.
