# Write a one-line Python generator expression that provides an infinite stream
#of unique integers that are evenly divided by any of the ascii values for
#the characters in “jean”.

# There are likely many ways to do this correctly.
# I have made some assumptions - that sequential ordering is alright,
# and that although python3 technically does not have a integer limit
# we want to have some kind of reasonable size limit based on max pointer size
# If we were in python 2 we would need to limit the range to sys.maxint
# I have explicitly imported things here as well just for clarity although

Open up your settings in Atom, select 'install' from the menu on the left and search for these helpful plugins:

1. Atom-beautify

    Probably the best of all... Clean up and indent HTML, CSS, JavaScript, PHP, Python, Ruby and more...!
    Right click to use!

2. Open-in-browser

Pretty obvious by the name, allows you to open files in your browser from Atom by right clicking!

#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault
