TL;DR

Create 5GB FreeBSD image.
Install FreeBSD on xhyve.
Mount host directory.

Requisites

This is a small demo of how to create a library in Rust and call it from Python (both CPython and PyPy) using the CFFI instead of ctypes.

Based on http://harkablog.com/calling-rust-from-c-and-python.html (dead) which used ctypes

CFFI is nice because:

Reads C declarations (parses headers)
Works in both CPython and PyPy (included with PyPy)
Lower call overhead than ctypes

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

Does the design expect failures to happen regularly and handle them gracefully?
Have we kept things as simple as possible?

Installation

Installing Supervisor on OS X is simple:

sudo pip install supervisor

This assumes you have pip. If you don't:
