Create a Meteor app and put the client_/server_ files in a client/server directories. Also, create a public dir to save the uploaded files.

// This gist is meant to help you load a json datafile into a Meteor application.  More specifically, it's useful to migrate or bootstrap a Mongo datacollection.
// The easiest way to do this task is to open up three command shell windows.  
// As a few of the commands will take over the command shell and direct their output to stdout.  


// first, export your data to a file
// data.json

// run mongod so we can create a staging database
// not that this is a separate instance from the meteor mongo and minimongo instances

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo
