Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

Ruby on Rails Windows Troubleshooting Tips & Survival Guide

Intro/Overview

The Ruby on Rails Windows Troubleshooting tips & Survival Guide is a random catalogue of issues I faced working with Ruby on Rails on Windows (Windows 7 specifically). This guide is not exhaustive, but covers many of the challenges that causes Windows Ruby developers to jump ship to Linux or Mac. If you're reading this guide then you're probably new to Ruby/Rails, so also included is more general beginner advice to help you get going.

Personal Side Note

Before you follow this guide, I strongly recommend you consider using Linux or Mac OS X for Ruby Development instead. Looking to prove a point as a challenge, I ignored this strongly given advice while learning Ruby/Rails. While I eventually did succeed in getting Ruby on Rails to work in Windows, it was not easy, and I easily lost 40+ hours on StackOverFlow to Windows/Ruby configuration issues--time I could have devoted to learning more about th
