Access SilverStripe framework outside of typical page controller. Rapid prototyping.
<?php
/**
* Include this file if you wish to tie into the SilverStripe framework to test your code in a separate workbench area
* without having to build a page controller, data object and then go through the full request cycle. This is good for
* rapid prototyping before rolling out any sort of final code. NOTE: This *is* suitable for use in the command line as
* well.

Hack to handle multiple Exception types with a single block
<?php
class Foo extends Exception {}
class Bar extends Foo {} // Bar is a technically different but Foo-like exception.
class Baz extends Exception {}
try {
throw new Foo();
} catch (Foo $e) {
echo 'Case 1';
} catch (Baz $e) {

When you're too stupid to realize you need to "git checkout [branch]" and not "cd" into it.
cd() {
if [ -d .git ] && [ ! -d $@ ]; then
git checkout "$@"
else
command cd "$@"
fi

Example of how you can ensure you have programmatic encapsulation and capture of all SilverStripe generated errors.
<?php
/**
* SilverStripe doesn't typically use exceptions, but we may still need a programmatic method of encapsulating code
* and catching errors. Here we can wrap code in a callback which will trigger an exception instead of user_error()'s.
*
* @param callable $closure
* @throws Exception
*/

Shader functions to facilitate rotation of vertex around point with a quaternion (Unity / HLSL / Cg)
// Full shader example demonstrating how to use a quaterionion to rotate a vertex around a specific point. Note that this is just a plain
// vanilla unlit shader which includes the necessary functions (see section below) and example code in the vertex shader.

// Forked from https://gist.github.com/nkint/7449c893fb7d6b5fa83118b8474d7dcb
// Converted from GLSL to Cg. For help with that, see https://alastaira.wordpress.com/2015/08/07/unity-shadertoys-a-k-a-converting-glsl-shaders-to-cghlsl/

using Valve.VR;
/// <summary>
/// Override the material and texture of the HTC Vive controllers, with your own material after SteamVR has loaded and
