Introduction

Docker.app will complain about incompatible processor, so we will use Docker Machine.

Instalation

Download Docker for Mac (Docker.app). It contains some binaries that are necessary.

brew install virtualbox docker-machine

Operation	Input	Result	Notes
map	`F[A]` , `A => B`	`F[B]`	Functor
apply	`F[A]` , `F[A => B]`	`F[B]`	Applicative
(fa, fb, ...).mapN	`(F[A], F[B], ...)` , `(A, B, ...) => C`	`F[C]`	Applicative
(fa, fb, ...).tupled	`(F[A], F[B], ...)`	`F[(A, B, ...)]`	Applicative
flatMap	`F[A]` , `A => F[B]`	`F[B]`	Monad
traverse	`F[A]` , `A => G[B]`	`G[F[A]]`	Traversable; `fa.traverse(f)` == `fa.map(f).sequence`; "foreach with effects"
sequence	`F[G[A]]`	`G[F[A]]`	Same as `fga.traverse(identity)`
attempt	`F[A]`	`F[Either[E, A]]`	Given `ApplicativeError[F, E]`

OS X 10.11 (El Capitan) / Node.js and io.js Developer Environment

Custom recipe to get OS X 10.11 El Capitan running from scratch with useful applications and Node.js Developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after fresh install.

After scouring the internet and piece-mealing together the correct way to do this, here is a step-by-step, all-in-one-place guide to making logback STFU when running your unit tests.

Here's how to do it

Save the following as logback-test.xml under src/test/resources:

<configuration>
  <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
      <pattern>%msg%n</pattern>
