HTTP/2 is here. Now let's encrypt and use it with nginx!

HTTP/2 has arrived in most recent browsers and is therefore ready to use (http://caniuse.com/#search=http2).

Generate lets-encrypt certificates

The Let's-Encrypt project allows you to generate SSL certificates for free. To start using it clone letsencrypt from github:

$ git clone https://github.com/letsencrypt/letsencrypt

Let's Encrypt with Nginx

Here's how I set up a tiny Nginx/Rails server that uses HTTPS via a Let's Encrypt issued certificate.

Server

I use the smallest DigitalOcean droplet (512 MB) here, which is built from the "Ubuntu Ruby on Rails on 14.04" image provided by them.

Here's a little walkthrough of how Yannick and I are using feature branches and pull requests to develop new features and adding them to the project. Below are the steps I take when working on a new feature. Hopefully this, along with watching the process on Github, will serve as a starting point to having everyone use a similar workflow.

Questions, comments, and suggestions for improvements welcome!

Start with the latest on master

When starting a new feature, I make sure to start with the latest and greatest codebase:

git checkout master

WebSockets - An Introduction

WebSockets is a modern HTML5 standard which makes communication between client and server a lot more simpler than ever. We are all familiar with the technology of sockets. Sockets have been fundamental to network communication for a long time but usually the communication over the browser has been restricted. The general restrictions

• The server used to have a permanent listener while the client (aka browser) was not designated any fixed listener for a more long term connection. Hence, every communication was restricted to the client demanding and the server responding.
• This meant that unless the client requested for a particular resource, the server was unable to push such a resource to the client.
• This was detrimental since the client is then forced to check with the server at regular intervals. This meant a lot of libraries focused on optimizing asynchronous calls and identifying the response of asynchronous calls. Notably t
