Fine-tuning a Keras model. Updated to the Keras 2.0 API.
'''This script goes along the blog post
"Building powerful image classification models using very little data"
from blog.keras.io.
It uses data that can be downloaded at:
https://www.kaggle.com/c/dogs-vs-cats/data
In our setup, we:
- created a data/ folder
- created train/ and validation/ subfolders inside data/
- created cats/ and dogs/ subfolders inside train/ and validation/
- put the cat pictures index 0-999 in data/train/cats

Drop-in utility to test your app subdomains with Capybara, Rspec, and a Javascript driver (Poltergeist, Webkit, or Selenium)
# Support for Rspec / Capybara subdomain integration testing
# Make sure this file is required by spec_helper.rb

def switch_to_subdomain(subdomain)
# lvh.me always resolves to 127.0.0.1
hostname = subdomain ? "#{subdomain}.lvh.me" : "lvh.me"
