Buildpacks

Heroku uses buildpacks to compile your application into a slug that is used across dynos for scaling horizontally quickly. A slug is a tar.gz archive of your app’s repository with certain pre-deploy features baked into the filesystem. Since everything to run your application is included in the archive, scaling becomes a simple matter of transferring it to a dyno, unpacking, and running the appropriate process. This is how Heroku achieves scaling-by-moving-a-slider.

For example, the Ruby buildpack will:

• install ruby locally
• install the jvm/jruby (if you’re using it)
• install/run bundler and install your gems to Rails.root/vendor
• create your database.yml (which ends up reading from your app’s environment variables)

# Given a weight, break down into buildup to work weight
# 45, 50, 65, 70, 75-80, 90, 100
#
# weight sizes: 2.5, 5, 10, 15, 25, 35, 45
# bar weight: 45
#
# example: final weight 155
#
# 45%: 69.75 - 45 = 24.75 / 2 = 12.375. we can choose 15 (for 75lbs or 48%), or 10 + 2.5 for something close but more weights
# TODO: choose less weights
