Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.

Building Docker image with Packer and provisioning with Ansible

Overview

Packer

Packer is used to build image from a base image, perform provisions and store (commit) the final image.
We use provisioners and Packer templates to do the actual work to create the final image.
We use Ansible for provisioning.

What follows is a technical test for this job offer at CARTO: https://boards.greenhouse.io/cartodb/jobs/705852#.WSvORxOGPUI

Build the following and make it run as fast as you possibly can using Python 3 (vanilla). The faster it runs, the more you will impress us!

Your code should:

Download this ~2GB file: https://s3.amazonaws.com/carto-1000x/data/yellow_tripdata_2016-01.csv
Count the lines in the file
Calculate the average value of the tip_amount field.

1. Install dependencies for PHP 7.1

$ brew update
$ brew tap homebrew/dupes
$ brew install autoconf automake gmp homebrew/versions/bison27 gd freetype t1lib gettext zlib mcrypt

2. Configure PHP 7.1

$ git clone --depth=1 https://github.com/php/php-src.git
$ cd php-src

$ ./buildconf
