Direnv and SDKMAN integration

Motivation

In a time when you work on multiple projects with different development environments (mostly in JVM ecosystem), It's hard and repetitive work to change your env or java version, etc. I found the integration between sdkman and direnv as a solution for myself.

Requirments

• Install sdkman SDKMAN! is a tool for managing parallel versions of multiple Software Development Kits on most Unix based systems.
• Install direnv direnv is an extension for your shell. It augments existing shells with a new feature that can load and unload environment variables depending on the current directory.

Category theory jargon cheat sheet

A primer/refresher on the category theory concepts that most commonly crop up in conversations about Scala or FP. (Because it's embarassing when I forget this stuff!)

I'll be assuming Scalaz imports in code samples, and some of the code may be pseudo-Scala.

Functor

A functor is something that supports map.

Installing Supervisor on OS X is simple:

sudo pip install supervisor

This assumes you have pip. If you don't:
