Enables PostgreSQL interval datatype support (as ActiveSupport::Duration) in Ruby on Rails from 4.1 to 6.0
# Enables PostgreSQL interval datatype support (as ActiveSupport::Duration) in Ruby on Rails 4.1.

# add the interval type to the simplified_type list. because this method is a case statement
# we can't inject anything into it, so we create an alias around it so calls to it will call

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)

A proof that Promises/A is a Monad
//-------------------------------------------------------------
//
// Hypothesis:
//
// Promises/A is a Monad
//
// To be a Monad, it must provide at least:
// - A unit (aka return or mreturn) operation that creates a corresponding
// monadic value from a non-monadic value.
// - A bind operation that applies a function to a monadic value
