Difference between png-Interlaced, jpg-progressive AND png-non-Interlaced, jpg-baseline
View gist:b13baec4b5142a527399693f8829547d
Interlaced image loads an early degraded version of the whole image as soon as possible and then progressively renders the image to clear state.
Non-interlaced image will load up in tiles showing clear image in each tile as it progresses to load in the image.
For .jpg the interlaced = progressive and not interlaced = baseline.

How to Run a Rails App in Production Locally
View running_app_in_production_locally.markdown
  1. Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
  2. bundle
  3. Run RAILS_ENV=production rake db:create db:migrate db:seed
  4. Run rake secret and copy the output
  5. From the command line: export SECRET_KEY_BASE=output-of-rake-secret
  6. To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
  7. Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
