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.
# Based on https://gist.github.com/clarkdave/6529610
require 'active_support/duration'
# add a native DB type of :interval
ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::NATIVE_DATABASE_TYPES[:interval] = { name: 'interval' }
# 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

Compile FFmpeg on Ubuntu

This guide supports Ubuntu Precise Pangolin 12.04, Ubuntu Oneiric Ocelot 11.10, Ubuntu Natty Narwhal 11.04, and Ubuntu Maverick Meerkat 10.10. Separate guides are available for Ubuntu Lucid Lynx 10.04 and Ubuntu Hardy Heron 8.04. This guide will enable several external encoding and decoding libraries: libfaac (AAC encoder), libfdk-aac (AAC encoder), libmp3lame (MP3 encoder), libopencore-amr (AMR encoder/decoder), librtmp (for additional RTMP protocols), libtheora (Theora encoder), libvorbis (Vorbis encoder), libvpx (VP8 encoder/decoder), and libx264 (H.264 encoder). These are optional and may be omitted if desired. This guide will also install many filters (see the filter list in the [Filtering Guide](https://ffmpeg.org/trac/ffmpeg/wiki/Fi

Setup Rails app with Paperclip 5, Amazon S3 and Heroku

Setting Amazon S3 for Paperclip and Heroku

The latest Paperclip release 5.1.0 has changed a little bit the way to set it up with Amazon S3 service (Amazon Simple Storage Service). Moreover, after googling a lot here and there, we could see many solutions and settings, some of them being outdated, some - often different and did not work well. So I decided to summarize in one replace all the steps needed to set up your Rails application deployed on Heroku and be able to use it with Paperclip 5 and Amazon S3 service.

In case you don't know, Heroku does not allow your Rails application to write and offers read only access. What means that you can't use Paperclip and save your files to Heroku's file system.

So you will have to find a way to upload/store/read your files. As stated in Paperclip documentation, Paperclip ships with 3 storage adapters:

# gradual engagement is needed, to allow admin creation of users
# users should create authorization data only when they need to
# access some system feature that requires authentication
# So ... our gradual engagement scheme for authlogic:
# 1. admin creates user, setting only name and phone number (required)
# admin may set email address (optional)
# 2. user is sent email invitation with link to activate their account
# admin can re-send email at user's request
# 3. user sets login and password/password_confirmation using activation form
