# We've been storing some JSON in a string field in our database,
# and needed to extract it to get something resembling reasonable
# performance on queries.
# 
# Building a manual query of either INSERT INTO () SELECT or
# UPDATE forms, use it like:
# 
#   SELECT #{json('login')}
# 
# If you have integer fields that are sometimes null or not present:

#!/usr/bin/env ruby

# Sets up remote tracking if you forgot to --track a branch,
# or if you're setting up a new branch.
# Save in ~/bin/ or somewhere else on your path.

# Usage:
#   git track [[remote] branch]
# remote defaults to 'origin'
# branch defaults to the name of the current local branch

If one was inclined to use the acts_as_yaffle pattern, they would probably use the second one, rather than the heavily cargo-culted first one.

# For "Classic" style/top-level type of apps do something like: 
#
# configure :development do
#   require File.join(File.dirname(__FILE__), 'sinatra_reloader')
#   set :reload_paths, [File.join(File.dirname(__FILE__), '**', '*.rb')]
# end
#
# For "Modular" style/Sinatra::Base subclasses:
#
# configure :development do

Usage:

./vimeo.rb video-id [password] [output filename, no extension]

Known issues:

I should put some better arg handling in, if you download a video w/ password it will use the password as output filename.

# TODO: self, blog this.

# NUTSHELL: Have a database column with some JSON in it that you'd maybe like to pull out and index on?
# Here's your solution. The generated sql looks pretty gnarly but mysql ran through it stupidly fast.
# I shudder to think how long it'd take activerecord to load and update each record individually.

# USAGE: In a migration.
