1. Add gem 'will_paginate', '~> 3.0' to Gemfile
2. Add %w(will_paginate will_paginate/active_record).each {|lib| require lib} to config.ru
3. Assuming modular Sinatra, open Sinatra::Base and add include WillPaginate::Sinatra::Helpers so that all views can use will_paginate
4. In controller, @users = User.paginate(:page => params[:page], :per_page => 30)
5. In view, = will_paginate @users will generate the pagers

If you want to style your pagers

• Include this css in your layout
• Style it

# There are 3 levels of git config; project, global and system.

# project: Project configs are only available for the current project and stored in .git/config in the project's directory.
# global: Global configs are available for all projects for the current user and stored in ~/.gitconfig.
# system: System configs are available for all the users/projects and stored in /etc/gitconfig.

# Create a project specific config, you have to execute this under the project's directory.
$ git config user.name "John Doe"

# Create a global config

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
