| # This is a modification of the blogpost on how to use Mongoid and Sinatra. | |
| # Here is the original blogpost http://www.garrensmith.com/2010/09/11/Mongoid-sinatra.html | |
| # The modification lets you use Mongoid 3.0 with the new Moped driver | |
| # The new Moped driver uses the Sessions component to define the MongoDB connection rather | |
| # than the Mongo::Connection.new that is used in the case of the default Ruby driver. | |
| # Moped::Session.new vs Mongo::Connection.new | |
| # Mongoid.load!(yaml_config.yml) is used to build the config hash. Alternatively, the hash can | |
| # be built manually by using Mongoid.config {|config| ...} syntax. The config.sessions hash |

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

psql -U postgresSome 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)
