Haskell pair programming server via Vagrant

Installation

on a local virtualbox

1. Clone this repo
2. Install Vagrant and VirtualBox
3. vagrant up
4. vagrant ssh

This will create a clean dev environment with the newest GHC and Cabal. It also includes haskell-vim-now, a vim configured to be a Haskell IDE.

on a public pair programming server

1. Clone this repo
2. Install Vagrant
3. Sign up at DigitalOcean
4. Fill out your DigitalOcean client ID and API key in Vagrantfile
5. vagrant up --provider=digital_ocean
6. vagrant ssh

You'll be logged in to a newly created DigitalOcean "droplet."

ps: for some reason I had to create a ssh key with a password otherwise I could not get ssh access to the box

Included software

1. Ubuntu 14.04
2. GHC 7.8.4, Cabal 1.22
3. haskell-vim-now
4. SixArm git config
5. Firewall, hardened OpenSSH, Fail2ban
6. Oh My ZSH, Tmux/wemux

Pairing

To pair program with someone you can give them login access by running

pair github_name

They connect to your server by ssh-add'ing their Github SSH key and running ssh friend@[your-server-ip].

When you're done working with them, run

unpair
