How to copy production database on AWS RDS(postgresql) to local development database.
  1. Change your database RDS instance security group to allow your machine to access it.
    • Add your ip to the security group to acces the instance via Postgres.
  2. Make a copy of the database using pg_dump
    • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
    • you will be asked for postgressql password.
    • a dump file(.sql) will be created
  3. Restore that dump file to your local database.
    • but you might need to drop the database and create it first
    • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>
  • the database is restored

A Rubocop wrapper that checks only added/modified code
#!/usr/bin/env ruby
# A sneaky wrapper around Rubocop that allows you to run it only against
# the recent changes, as opposed to the whole project. It lets you
# enforce the style guide for new/modified code only, as opposed to
# having to restyle everything or adding cops incrementally. It relies
# on git to figure out which files to check.
#
# Here are some options you can pass in addition to the ones in rubocop:

Ruby 2.0 CA cert issue fix
# If you're having cert issues on ruby 2.0.0-p0, the issue is most likely that ruby can't
# find the required intermediate certificates. If you built it via rbenv/ruby-build, then
# the certs are already on your system, just not where ruby expects them to be.
# When ruby-build installs openssl, it installs the CA certs here:
~/.rbenv/versions/2.0.0-p0/openssl/ssl/cacert.pem
# Ruby is expecting them here:
$(ruby -ropenssl -e 'puts OpenSSL::X509::DEFAULT_CERT_FILE')
# Which for me, is this path:

Inspired by @JEG2's talk at Rubyconf... Any ruby object, as a webapp! 'Cause we can. :-)
require 'rubygems'
require 'rack'

class << self
define_method :call do |env|
func, *attrs = env['PATH_INFO'].split('/').reject(&:empty?)
[200, {}, send(func, *attrs)]
