How to import the sakila database into MySQL

##The old method, via phpmyadmin The first time I downloaded the sakila database, I did it via phpmyadmin using Import at the Server level. I did not use a command line. I did not create a database called Sakila and then populate it: the .sql files delete and re-create the database anyway. I imported the schema file and then the data file, ignoring the .mwb file, which is only useful if you have MySQL Workbench installed, at which point it supplies you a database diagram. A nice-to-have, but not critical in creating a database.

When I imported the files, I had to untick the box that said "Allow the interruption of an import in case the script detects...". I also had to temporarily change MySQL's maximum import size (using a line of SQL I found online): https://dev.mysql.com/doc/refman/5.5/en/packet-too-large.html

Today I find this method does not work. I get an error about geometry (which is due to a commented out line in the SQL). Even when I remove the commented out lines (whose purpose is to create spa

Vagrant Cheat Sheet

Typing vagrant from the command line will display a list of all available commands.

Be sure that you are in the same directory as the Vagrantfile when running these commands!

Creating a VM

  • vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
  • vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

  • vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)

Python merge sort in place, so space complexity is O(1)
import random
def merge_sort(xs):
"""Inplace merge sort of array without recursive. The basic idea
is to avoid the recursive call while using iterative solution.
The algorithm first merge chunk of length of 2, then merge chunks
of length 4, then 8, 16, .... , until 2^k where 2^k is large than
the length of the array
