Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

XCode is installed (via the App Store)
XCode command line tools are installed (xcode-select --install will prompt up a dialog)
Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Trigonometry

const float PI = 3.1415926535897932384626433832795;
const float PI_2 = 1.57079632679489661923;
const float PI_4 = 0.785398163397448309616;

float PHI = (1.0+sqrtf(5.0))/2.0;

Vagrant with Ansible Provisioner on Windows

Long story short, ansible does not work on a Windows control machine, so you basically have to:

either run ansible --connection=local ... in the target vm
set up a separate control vm where ansible is installed via shell provisioner

Below are Vagrantfile examples for both approaches

Within the Target VM

“It ain’t what you don’t know that gets you in trouble. It’s what you know for sure that just ain’t so.” -- Mark Twain

CPU

64-bit, 2-core, 4-thread, 8G 1333MHz DDR3 2-channel, 2.3 ~ 2.9 GHz, GPU 650 MHz ~ 1.3 GHz dual monitor

Post Manjaro install

This is my little Christmas-break experiment trying to (among other things) reduce the amount of generated code for containers.

THIS CODE WILL CONTAIN BUGS AND IS ONLY PRESENTED AS AN EXAMPLE.

The C++ STL is still an undesirable library for many reasons I have extolled in the past. But it's also a good library. Demons lie in this here debate and I have no interest in revisiting it right now.

The goals that I have achieved with this approach are:

	; ___ _ __ ___ __ ___
	; / __\|_ _ __ _\| \|_____ / /\| __\|/ \_ )
	; \__ \ ' \/ _` \| / / -_) _ \__ \ () / /
	; \|___/_\|\|_\__,_\|_\_\___\___/___/\__/___\|

	; An annotated version of the snake example from Nick Morgan's 6502 assembly tutorial
	; on http://skilldrick.github.io/easy6502/ that I created as an exercise for myself
	; to learn a little bit about assembly. I think I understood everything, but I may
	; also be completely wrong :-)

	# Hello, and welcome to makefile basics.
	#
	# You will learn why `make` is so great, and why, despite its "weird" syntax,
	# it is actually a highly expressive, efficient, and powerful way to build
	# programs.
	#
	# Once you're done here, go to
	# http://www.gnu.org/software/make/manual/make.html
	# to learn SOOOO much more.

	// Normalize input position to unit sphere to simplify required ops
	float3 P = normalize(position);

	// Get octant index
	float3 side = P >= 0 ? 1 : 0;
	float octant_index = side.x + side.y * 2 + side.z * 4;

	// Project onto octahedron face, then onto each x/y plane
