I'm admittedly very biased when it comes to this question, because I really love development in Linux and do think it is better, but in the case of Ruby, I also think it makes everything easier. That said, I feel like I owe you more of an explanation than simply "I also think it makes everything easier", so you'll find that explanation below... with my opinions inevitably mixed in. :)

First off, yes, Ruby does run on Windows! I've only ever run Ruby on Windows once (testing a script I wrote for a friend, using my mom's desktop), but I think I used RubyInstaller to get it installed.

I do have a few concerns about Ruby in Windows though:

1. Ruby is designed and built for the most part by people on *nix (Unix and Linux) systems, and then adapted for use in Windows; the vast majority of people in the community are on *nix systems; and Ruby applications running in production are almost always running on Linux. Because of this, I've always felt that support for Ruby in Linux has

Easy Minecraft Server on AWS EC2

Note: "easy", assuming you're familiar with Linux, have an AWS account, and already have a .pem registered there.

I hunted this information down from a handful of places, so nothing particularly new here, but hopefully this tl;dr saves someone else some time.

• create a new Ubuntu EC2 instance
• select type t2.small (for 2GB of RAM)
