1. pg_dump is a nifty utility designed to output a series of SQL statements that describes the schema and data of your database. You can control what goes into your backup by using additional flags.
   Backup: pg_dump -h localhost -p 5432 -U postgres -d mydb > backup.sql

   Restore: psql -h localhost -p 5432 -U postgres -d mydb < backup.sql

   -h is for host.
   -p is for port.
   -U is for username.
   -d is for database.

Using Swift libraries in Python

So... this is obviously totally, 100%, like for. real. not. supported. by. Apple. …yet?

But still... I thought it was pretty badass. And, seeing how there's already a Swift buildpack for Heroku you could move some slow code into Swift can call it as a library function. But, you know, not in production or anything. That would be silly, right?

Now, having said that, the actual Python/Swift interop may have bugs. I'll leave that as an exercise to the reader.

How to get Python code calling Swift functions:

#!/bin/bash

# DESCRIPTION:
#
#   Set the bash prompt according to:
#    * the active virtualenv
#    * the branch of the current git/mercurial repository
#    * the return value of the previous command
#    * the fact you just came from Windows and are used to having newlines in
#      your prompts.
