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)

Config. file uploader task for Capistrano 3
# lib/capistrano/tasks/config_files.cap
#
# Capistrano task to upload configuration files outside SCM
# Jesus Burgos Macia

# This allows us to have server's config files isolated from development ones.
# That's useful for several reasons, but the most important is that you can
# ignore files from repository.
#
# The task will upload all files found in

Multiple Python installations on OS X

Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9
