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)

/**

Ruby to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in Ruby and Rust so that programmers most comfortable with Ruby can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?

Server-Sent Events Demo

Server-Sent events is a specification for implementing server-side-push for web frontend applications, through plain-old HTTP.

It is best contrasted with WebSockets, which offer a full-duplex messaging channel over a custom protocol, operating within a single TCP connection (with an HTTP-compatible handshake).

Cheatsheet: pyenv, virtualenvwrapper, and pip

Installation (for Mac OS)

Install pyenv with brew

brew update
brew install pyenv

	# -fmodules: enables modules so you can import with `@import AppKit;`
	# -mmacosx-version-min=10.6: support older OS X versions, this might increase the binary size

	clang main.m -fobjc-arc -fmodules -mmacosx-version-min=10.6 -o main
