Installing rbx-2.0.0-dev with Ruby 1.9 support using rbenv can be a tad tricky. This is what I did to get up and running, you'll need another version of ruby already installed as well as rake.

The basic outline:

1. Clone Rubinius HEAD from github
2. Configure installation for rbenv and 1.9 support
3. Install Rubinius
4. Configure your $PATH to use Rubinius gems
5. Start using Rubinius

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

The reason why you might get certificate errors in Ruby 2.0 when talking HTTPS is because there isn't a default certificate bundle that OpenSSL (which was used when building Ruby) trusts.

Update: this problem is solved in edge versions of rbenv and RVM.

$ ruby -rnet/https -e "Net::HTTP.get URI('https://github.com')"
net/http.rb:917:in `connect': SSL_connect returned=1 errno=0 state=SSLv3
  read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)

You can work around the issue by installing a certificate bundle that you trust. I trust Mozilla and curl.

EC2 Instance Connect meets AWS Session Manager via SSH

Both things have been introduced recently, and let you access even private ec2 instances

1. Without VPN
2. No open SSH port
3. Authentication / Authorization is fully delegated to IAM
