Beyond Angular and Backbone with Unidirectional apps

What is a unidirectional app?

Unidirectional is a term coined by React engineers to describe the data flow of an application. Unidirectional apps employ functional reactive programming techniques such as immutability, purity, and most importantly unidirectional (as opposed to bidirectional) data flow.

A unidirectional app is defined by no mutable references no two-way references between concerns.

Located in alphabetical order (not prefer)

ab – slow and single threaded, written in C
apib – most of the features of ApacheBench (ab), also designed as a more modern replacement, written in C

baloo – Expressive end-to-end HTTP API testing made easy, written in Go (golang)

Here's how to install PostgreSQL and have it run automatically at startup, on an Ubuntu 10.04 virtual machine using Vagrant. This took me a while to figure out:

Add the default lucid32 base box to your vagrant, if you haven't already:

host> vagrant box add lucid32 http://files.vagrantup.com/lucid32.box

Now make a new lucid32 virtual machine and install postgresql on it:

	val scalacOptions = Seq(
	"-encoding",
	"utf-8", // Specify character encoding used by source files.
	"-Ybackend-parallelism", //
	"8",
	"-explaintypes", // Explain type errors in more detail.
	"-feature", // Emit warning and location for usages of features that should be imported explicitly.
	"-unchecked", // Enable additional warnings where generated code depends on assumptions.
	"-Xcheckinit", // Wrap field accessors to throw an exception on uninitialized access.
	// "-Ymacro-annotations", // Enable support for macro annotations, formerly in macro paradise.
