Rust and Travis CI cache

Using Travis CI's cache is very useful and helps cut Rust job times way, way down. However, the way that the default caching for Cargo is set up means it will quickly bloat.

Travis currently checks ~/.cargo and target/ for any changes from the current cache after a build. There will always be changes in target/ if the source has changed, which it usually does when a Travis build runs. This means new incremental object files, fingerprints, and build script compilation files are being added to the cache every build.

About

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:

Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
Simple - This solution has few dependencies, readily available packages and minimal configuration.
Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43

Prerequisites

This is a userscript with a light-on-dark content-centered style for plain/text documents.

Installation

To install this userscript in Chrome, save the JavaScript file and drag it onto the chrome://extensions page.

If you use ViolentMonkey, TamperMonkey, or GreaseMonkey, install from one of these links:

New home: https://github.com/glebm/render-whitespace-on-github

This lets you load application JavaScript asynchronously from <head>. Compatible with Turbolink v2, v5.0, v5.1, jquery-turbolinks, and no Turbolinks. Compatible with all browsers and IE9+ (only IE10+ will actually benefit from this though).

How to use this:

Add the HTML snippet just before the closing </body> tag.
Add the on_page_load.js script to the beginning of your application.js, and use window.App.onPageLoad(...) instead of document.addEventListener('DOMContentLoaded', ...) and jQuery(($) -> ...) everywhere.
Include your JavaScript like so:
```
<head>
```

	# View registry settings
	Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Enum\HID\\\Device` Parameters FlipFlopWheel -EA 0

	# Change registry settings
	# Reverse mouse wheel scroll FlipFlopWheel = 1
	# Normal mouse wheel scroll FlipFlopWheel = 0
	Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Enum\HID\\\Device` Parameters FlipFlopWheel -EA 0 \| ForEach-Object { Set-ItemProperty $_.PSPath FlipFlopWheel 1 }

	# Restore default scroll direction
	# Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Enum\HID\\\Device` Parameters FlipFlopWheel -EA 1 \| ForEach-Object { Set-ItemProperty $_.PSPath FlipFlopWheel 0 }
